Description

Technical Field

[0001] The utility model relates to the technical field of wheel chocks for passenger elevators, in particular to an apron-pushed handheld wheel chock. Background Art

[0002] A handheld wheel chock is a device that is composed of a car wheel chock with a handheld bar added. It is used to assist the braking of the passenger ladder when docking with an aircraft, and can prevent accidental collisions between the passenger ladder and the aircraft. The traditional integrated handheld wheel chock is designed as an integral whole. In actual use on the apron, it is heavy and difficult to move. When aiming at the wheels of the passenger ladder, it is easy to collide with the front bumper of the vehicle if the angle is not careful, which may lead to the hidden danger of unsafe incidents. In addition, the existing handheld wheel chocks are heavy, which makes it inconvenient for the passenger ladder commander to operate them. It is even more difficult to use the handheld wheel chock while commanding the passenger ladder. Therefore, it is necessary to improve the defects of the traditional handheld wheel chock and design an apron push-type handheld wheel chock. Utility Model Content

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. The apron-pushed handheld wheel chock uses a fixed rod one and a fixed rod two to move the fixed rod two in the direction away from the clamping block, then rotate the fixed rod one while rotating the fixed rod two until the bottom of the fixed rod one overlaps with the top of the fixed rod two, then rotate the clamping frame until the inner wall of the clamping frame limits the side of the positioning block, then rotate the fixed plate on the inner wall of the U-shaped frame, thereby using the fixed plate to drive the wheel chock body to move, and then set up the device. Compared with traditional devices, this device ensures that the wheel chock support bar is level with the ground, can effectively prevent collision with the passenger elevator, and is easy to tie up and can be placed on the passenger elevator.

[0012] 2. The apron-pushed handheld wheel chock uses the inner frame of the handrail in coordination with the outer frame of the handrail to move the inner frame of the handrail away from the outer frame of the handrail. At this time, the inner frame of the handrail is pulled and moved using the universal wheel and roller auxiliary devices, and the wheel chock body is assisted in limiting the position using the card block.
