Description

Technical Field

[0001] This utility model relates to the technical field of parking facilities for apron vehicles, and in particular to wheel chock devices for apron vehicles. Background Technology

[0002] In the unique working environment of an airport apron, the safe parking of vehicles on the apron is of paramount importance. Due to the potential for slight slopes on the apron surface, the influence of wind (especially the powerful wake generated during aircraft takeoff and landing), and the varying load conditions of the vehicles (whether empty or fully loaded), relying solely on the vehicle's parking brake system poses safety risks.

[0003] Wheel chocks, as auxiliary parking devices, can prevent vehicles from accidentally sliding by physically blocking them and avoid collisions with ground equipment and personnel on the tarmac. In daily operation, tarmac vehicles are usually equipped with wheel chocks on both the front and rear sides of each individual wheel, that is, each wheel is equipped with two wheel chocks. After the tarmac vehicle is parked, staff need to place a wheel chock in front of and behind each wheel in turn, which is cumbersome to use and inconvenient to remove. Utility Model Content

[0004] The purpose of this invention is to provide a wheel chock device for apron vehicles that is relatively easy to pick up and use.

[0005] This utility model is implemented by the following technical solution: a wheel stop device for apron vehicles, comprising two wheel stops, one of which has an L-shaped telescopic rod fixed to its side wall, and a telescopic limiting sleeve sleeved on the L-shaped telescopic rod; the other wheel stop has a connecting handle fixed to its side wall, the end of the telescopic limiting sleeve is connected to the connecting handle, the telescopic limiting sleeve has several limiting holes, and a limiting clip is connected to the telescopic rod, the limiting clip being movably placed in the corresponding limiting hole.

[0006] Furthermore, the limiting device includes a limiting spring and a locking post. The L-shaped telescopic rod has an installation hole. The bottom end of the limiting spring is fixed to the bottom of the installation hole. The top end of the limiting spring is connected to the bottom end of the locking post. The locking post slides along the installation hole. The top end of the locking post is spherical.

[0007] Furthermore, both of the wheel stops have arc-shaped surfaces on their force-bearing surfaces, and anti-slip textures are provided on the force-bearing surfaces of the wheel stops.

[0008] Furthermore, the wheel chock is made of rubber.

[0009] Furthermore, the end of the telescopic limiting sleeve is hinged to the connecting handle.

[0010] Furthermore, a handle is bent and fixed at the end of the connecting handle, and a return spring is connected between the handle and the telescopic limiting sleeve.

[0011] Furthermore, the sidewalls of the two wheel stops are respectively fixed with connecting plates by screws, and the L-shaped telescopic rod and the connecting handle are welded and fixed to the corresponding connecting plates.

[0012] The advantages of this invention are as follows: Two wheel stops are connected together by an L-shaped telescopic rod, a telescopic limiting sleeve, and a limiting clip, making them easy to handle and carry. Depending on the size of the vehicle's tires, the distance between the two wheel stops can be adjusted simply by extending the L-shaped telescopic rod along the telescopic limiting sleeve to accommodate the corresponding vehicle tire. Under the action of the return spring, the connecting handle drives the corresponding wheel stop to rotate inward, further securing it under the wheel and providing a more effective blocking effect.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figures 1 to 3 As shown, this embodiment provides a wheel chock device for apron vehicles, comprising two wheel chocks 1 made of rubber. The force-bearing surfaces of the two wheel chocks 1 are arranged opposite each other and are both arc-shaped. The force-bearing surfaces of the wheel chocks 1 are provided with anti-slip textures to effectively increase the friction with the vehicle tires. The sidewalls of the two wheel chocks 1 are respectively fixed with connecting plates 8 by screws for easy assembly and disassembly. The plate surface of the connecting plate 8 of one wheel chock 1 is welded and fixed to one end of an L-shaped telescopic rod 2. A telescopic limiting sleeve 3 is slidably fitted on the other end of the L-shaped telescopic rod 2. A connecting handle 4 is welded and fixed to the connecting plate 8 of the other wheel chock 1, and the end of the telescopic limiting sleeve 3 is connected to the connecting handle 4. Connecting the two wheel chocks 1 together makes them easy to handle and carry. Depending on the size of the vehicle tires, the distance between the two wheel chocks 1 can be adjusted by adjusting the telescopic extension of the L-shaped telescopic rod 2 along the telescopic limiting sleeve 3 to meet the needs of the corresponding vehicle tires.

[0021] The telescopic limiting sleeve 3 has several limiting holes 3.1. A limiting clip 5 is connected to the telescopic rod. The limiting clip 5 includes a limiting spring 5.1 and a clip 5.2. The L-shaped telescopic rod 2 has a mounting hole 2.1. The bottom end of the limiting spring 5.1 is fixed to the bottom of the mounting hole 2.1. The top end of the limiting spring 5.1 is connected to the bottom end of the clip 5.2. The clip 5.2 slides along the mounting hole 2.1. The top end of the clip 5.2 is spherical. The top end of the clip 5.2 of the limiting clip 5 is movably placed in the corresponding limiting hole 3.1. When the distance between the two wheel stops 1 is adjusted, under the action of the limiting spring 5.1, the top end of the clip 5.2 will engage in the corresponding limiting hole 3.1, which plays an effective limiting role, keeps the distance between the two wheel stops 1 unchanged, and effectively blocks the vehicle.

[0022] The end of the telescopic limiting sleeve 3 is hinged to the connecting handle 4, and the connecting handle 4 can rotate around the hinge point; the end of the connecting handle 4 is bent and fixed with a handle 6, and a return spring 7 is connected between the handle 6 and the telescopic limiting sleeve 3; when the device needs to be placed under the wheel, hold the handle 6 to compress the return spring 7, and the connecting handle 4 drives the wheel stop 1 to rotate outward, making it easier to place the two wheel stops 1 under the wheel. Then release the handle 6, and under the action of the return spring 7, the connecting handle 4 drives the wheel stop 1 to rotate inward, which is more conducive to locking under the wheel and playing a more effective blocking role.

[0023] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
