There is an existing trolley positioning device that enables the trolley to be accurately positioned on the casting production line. How to make the trolley positioning device accurately positioned, have a longer service life, be convenient and fast in replacing parts, and save costs is a problem that needs to be solved. Summary of the Invention
[0003] In order to solve the above technical problems, the utility model provides a trolley positioning device with a long service life, simple structure, high safety, and capable of accurately transporting the formwork.
[0004] The technical solution adopted by the utility model is a lifting trolley positioning device, which includes a bracket, a driving hook, a driven hook, a linkage rod, a linkage pin shaft, a cylinder, a hook pin shaft, a cylinder tail pin shaft, a brake block, and a self-lubricating rod end joint bearing. The driving hook and the driven hook are fixed on the bracket by the hook pin shaft. Both ends of the linkage rod are connected with self-lubricating rod end joint bearings. The two rod end joint bearings are respectively fixed on the driving hook and the driven hook through the linkage pin shaft. The shaft passes through the hook and the rod end joint bearing. The cylinder head is connected with the tail of the driving hook, and the cylinder tail is connected with the bracket through the cylinder tail pin shaft.
[0005] Furthermore, the bracket is connected to the mounting frame by bolts.
[0006] Furthermore, the self-lubricating rod end joint bearing and the rod end joint bearing are fixed at both ends of the linkage rod by nuts.
[0007] Furthermore, the hook pin shaft and the cylinder tail pin shaft are fixed on the bracket by bolts.
[0008] Furthermore, the brake block is respectively fixed on the driving hook and the driven hook by bolts.
[0009] Compared with the prior art, the utility model has remarkable advantages and beneficial effects:
[0010] (1) Under the condition of ensuring production and safety, the mechanism controls the angle of the driving hook through the extension of the cylinder, and then can appropriately adjust the angle of the extended driven hook through the rod end joint bearing, so that the hook is in close contact with the trolley, preventing the trolley from sliding relative to the mechanism due to the shaking or inaccurate positioning of the trolley during operation, thus avoiding unnecessary losses and injuries caused by subsequent action deviations. The appearance of the trolley positioning device further improves the safety and stability of the trolley during transportation.
[0011] (2) This design has a simple structure, saves working hours, and is easy to disassemble and assemble. For the hook with a large degree of wear, only the brake block at the front end of the hook needs to be replaced; the telescoping of the cylinder provides a stable tension force for the manipulator.
