Development of automatic support device for pipe pile mould

2019-07-26


At present, concrete pipe piles are widely used in various infrastructure engineering fields as an emerging cement product. The pipe pile mold is composed of two upper and lower semi-cylindrical molds, and the upper and lower molds are locked by bolts and produced by centrifugation. In order to improve the structural strength of the mold, an annular reinforcing rib plate is evenly distributed along the axial direction of the outer surface of the mold, and each reinforcing rib plate is respectively disposed on the outer peripheral section of the mold, and the outer surface of the mold is further distributed along the axial direction thereof for facilitating centrifugation. Multiple running wheels. On the lower mold of the mold, a plurality of mold bolts are hingedly fixed by a pin shaft. When the upper mold and the lower mold are closed, the mold bolts on the lower mold need to be turned into the grooves of the upper mold side, and then the mold bolts are The locking is performed to fasten the upper and lower molds together to form a cylindrical mold. In the production process of the pipe piles, during the process of transferring the various processes of the mold, due to the accuracy of the lifting machinery and other transfer machinery, the joints of the upper and lower molds of the mold are inclined at a certain angle with the horizontal plane. Under the inclined attitude of the mold, the joint bolt is lower than the horizontal line, and the mold bolts that are lifted up are easy to fall under the action of gravity, which increases the labor intensity of the worker repeatedly lifting the bolts, and causes difficulty to lift the lifting equipment during the lifting and transporting process. At the same time, when the automation of each process of the production line is realized, it is impossible to accurately locate and detect due to the uncertainty of the position. Therefore, how to design a mold correction device and a correction system that can solve the above technical problems is a subject that the team has devoted research.
 
First, the experimental design
 
The object of the present invention is to provide a mold correcting device and a correction system, which can detect whether the joint of the mold is inclined with the horizontal plane in real time, and can quickly correct the mold back to be parallel with the horizontal plane when tilting, and the structure design is simple and convenient to use.
 
In order to achieve the above objectives, the structure and control system of the calibration device are designed by the working principle, and the design selection is based on the weight of the production line mold, the operation mode, the transfer operation of each process, and detailed analysis and calculation;
 
According to the calculation result, the motor is selected (Fig. 2): After the selection of the drive system and the detection mechanism of the device is completed, the overall mechanism is optimized and designed. The whole mechanism comprises a detecting mechanism mounted on the trolley for detecting the inclination angle of the mold joint and feeding back the mold state to the driving mechanism, and the upper surface of the platform of the trolley is installed with at least two rollers for placing the mold in the front-rear direction, one of which The roller is connected with a driving mechanism for rotating the driving mechanism. The driving mechanism performs the operation according to the detection result fed back by the detecting mechanism. When the detecting mechanism detects the inclination of the mold opening, the driving mechanism drives the mold to rotate until the opening is parallel with the horizontal plane.
 
Second, the basic principles
 
At least two rollers are mounted through the bearing housing at the front and rear positions of the upper surface of the platform of the trolley. The driving mechanism comprises a motor mounted on the trolley, the sprocket is mounted on the output shaft of the motor, and the driving auxiliary sprocket is connected to one end of the roller connected to the driving mechanism, and the main sprocket and the auxiliary sprocket are connected by a chain, adopting three-phase asynchronous AC motor drive.
 
The detecting mechanism adopts a sensor and a sliding control mechanism. The sensor is mounted on the sliding control mechanism. The sensor reciprocally scans along the front and rear direction of the mold through the sliding control mechanism, and transmits the scanning signal to the motor. The motor performs work according to the scanning signal, and the sliding control mechanism adopts a linear mode. The sensor is mounted on the sliding table of the linear module. The auxiliary design adopts a blowing device for cleaning the dust of the sensor. The blowing device is connected with the electromagnetic valve. The blowing device is controlled by a solenoid valve and is installed on the side of the trolley. The group is mounted on the base, the support plate is connected to the base, and the air blowing device is mounted on the support plate.
 
After adopting the above scheme, when the mold is transferred to the process, the device and the automatic control system are provided with a detecting mechanism on the lifting trolley, which can detect the inclination angle of the joint of the mold placed on the trolley and the horizontal plane in real time, and feedback the detected state of the trolley. For the driving mechanism, the driving mechanism performs the forward/reverse movement or the stop according to the detection result. When the detection of the inclination angle is not equal to zero, the driving mechanism drives the mold to rotate, so that the angle between the mold opening and the horizontal plane is zero, thereby effectively preventing the movement. The problem that the mold bolt is easy to fall when the joint is inclined with the horizontal plane eliminates the need for the worker to repeatedly support the mold bolt, reduces the labor intensity, and at the same time, the positioning is accurate when automatically lifting and transporting, and the detection and grasping is convenient, and the work efficiency is improved. The overall structure is simple in design and easy to use.
 
Third, the conclusion
 
The traditional production process of concrete pipe piles is relatively mature, and it belongs to the labor-intensive, high-intensity production mode. With the development of society and the change of labor structure, the production cost of this production mode is gradually increasing, and the labor force of this structure is coming. The lack of it, therefore, as a concrete pipe pile production enterprise to survive, the improvement of production process, the upgrading of production mode is urgent, the improvement of production process and the upgrading of automated equipment are essential, the application of automation equipment is relatively current production process and production. Mode, it is imperative to improve the equipment of the traditional production line and increase the auxiliary mechanism to adjust and improve the overall precision of the production line. The mold transfer is the most important part of the production process, and the research and development of the mold correction device and the overall control system is also the trend of the times.
 
The research on the mold calibration device and system has a great influence on the overall production process of the concrete prestressed pipe pile production process, the labor intensity of the employees, and the production efficiency. It provides conditions for the automation of the production process and the installation of the single-process automation equipment. The foundation for the improvement and improvement of process automation.
