Description

Technical Field

[0001] The utility model relates to the technical field of weighing platforms, in particular to an anti-collision device for a weighing platform. Background Art

[0002] The vehicle weighing platform is used to check the weight of vehicles passing through the platform. It is used in cement, building materials, logistics, chemical and other transportation weighing industries to calculate the weight of the vehicle for overweight detection. The sensor is the core component of the vehicle weighing platform and can simply and clearly reflect the weight of the vehicle. The vehicle weighing platform is usually used with a barrier machine so that vehicles can wait for detection in an orderly manner, and the interception plate of the barrier machine can also prevent vehicles from escaping detection.

[0003] After searching, an anti-collision device for a vehicle weighing platform disclosed in the prior art (application number: CN202222957035.7) records in the text that "a connecting concave plate is rotatably installed on one side of the barrier machine body, and an interception plate is snap-fitted and installed on one side of the connecting concave plate. Protective mechanisms are symmetrically arranged on both sides of the interception plate. The protective mechanism includes a hollow rod, one side of the hollow rod is evenly distributed on the interception plate, and an insertion rod is slidably installed on one side of the hollow rod. Threaded springs are evenly arranged on both sides of the interception plate, and the threaded springs are sleeved on the outside of the hollow rod and the insertion rod, and one end of the threaded spring is connected to a transverse plate."; Through the protective mechanism set up in this device, the vertical plates are squeezed, the vertical plates increase the contact surface with the vehicle body, increase the resistance, and squeeze the threaded springs. The spring allows the inserted rod to slide inside the hollow rod, allowing multiple threaded springs to work simultaneously to reduce the impact force, thereby protecting the interception plate body. However, when the device is actually used, only one side of the interception plate is likely to be hit. Therefore, the horizontal plate and vertical plates set on the other side of the interception plate do not provide corresponding beneficial effects for anti-collision, and will also increase the load on the interception plate when it rotates, thereby increasing the overall production cost of the device. At the same time, with the cooperation of the horizontal plate, vertical plate and threaded spring, although it can assist in reducing the impact force, the impact force still acts on the interception plate, thereby increasing the probability of bending and deformation of the interception plate, and the device is not provided with a corresponding distance warning device, which makes it impossible for the owner to accurately grasp the distance between the vehicle and the anti-collision device, thereby increasing the probability of a collision event.

At the same time, the moving plate and the extension blocks together form a structure in the shape of the Chinese character '丰' (feng).

[0010] Preferably, the extension block has a square tube structure. The size of the outer side surface of the extension block is adapted to the thickness size of the moving plate, and one end of the extension block away from the moving plate is fixedly connected to a cover plate through a buckle.
