Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic car unloading machines, in particular to a hydraulic car unloading machine lifting flap left and right synchronous anti-tilting mechanical device. Background Art

[0002] The hydraulic unloader uses a hydraulic system to unload cargo ranging from several tons to hundreds of tons in a few minutes. The process is to drive the truck to the hydraulic unloading platform, start the vehicle blocking device to block the wheels, and use the hydraulic system to lift one side of the platform, so that the platform tilts to a certain angle, allowing the bulk cargo to slide down automatically.

[0003] Publication No. CN212024680U discloses an intelligent unloading machine with an anti-tilting mechanism. The patent drives the truck onto the unloading platform and then starts the push rod motor, which is controlled by a control switch. The moving plate drives the clamping plate to move, and the clamping plate fixes the top of the truck. At the same time, the moving plate drives two steel ropes to move, and the two steel ropes respectively drive two large pulleys and two small pulleys to rotate. At the same time, the two steel ropes drive two mounting plates to move, and the two mounting plates stretch two limit springs, and the two limit springs absorb energy. At the same time, the two mounting plates drive two extrusion plates to move, and the two extrusion plates fix and clamp the two walking wheels, and fix and clamp the truck and the walking wheels, thereby preventing the truck from tilting during unloading, causing material spillage, causing losses and safety hazards to people. However, the patent still has the following problems in actual use:

[0004] The top of the truck is fixed by a clamping plate, and the two running wheels are fixedly clamped by two extrusion plates. The truck and the running wheels are fixedly clamped to prevent the truck from tilting during unloading and causing material spillage. However, in actual use, the truck is lifted by a connecting seat during unloading. After the connecting seat is lifted, the overall gravity of the truck is pressed on the top of the connecting seat. The connecting seat is not supported on both sides during the lifting process. If the truck is not stopped in the middle of the connecting seat, the connecting seat will be unevenly stressed after it is lifted, and the connecting seat is prone to tilting, which affects the unloading of the truck and poses certain safety hazards.

[0005] A hydraulic unloading machine lifting flap synchronous left and right anti-tilt mechanical device is proposed to solve the above-mentioned problems. Utility Model Content
