Description

Technical Field

[0001] The utility model relates to the technical field of aircraft wheel chocks, in particular to an aircraft wheel chock with an alarm function. Background Art

[0002] When an aircraft is parked, aircraft wheel chocks are usually used to brake the aircraft wheels to prevent the aircraft from slipping. Most aircraft wheel chocks are black rubber or yellow metal blocks.

[0003] Currently, the aircraft wheel chocks used at airports are all single units. After the aircraft lands, one wheel chock is placed in front of and behind the tire respectively to prevent the tire from slipping. However, since personnel need to lift and place the wheel chocks one by one when placing and removing them, it may cause mistakes when personnel place the wheel chocks, resulting in the wheel chocks not fitting the aircraft tire, affecting the braking of the aircraft tire. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose an aircraft wheel chock with an alarm function.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: an aircraft wheel chock with an alarm function, including two wheel chock bodies. Sensors are arranged on one side of each of the two wheel chock bodies. An adjusting device is arranged between the two wheel chock bodies. Auxiliary devices are arranged on one side of each of the two wheel chock bodies. The adjusting device includes a round hole frame. The inner wall of the round hole frame is rotatably connected with a bidirectional screw. The thread shape on the surface of the bidirectional screw is arranged symmetrically in opposite directions. Two screw hole blocks are symmetrically threadedly connected to the surface of the bidirectional screw. The two screw hole blocks are respectively fixedly connected to the two wheel chock bodies. The middle of the bidirectional screw is fixedly connected with an operation block. The operation block is located inside the round hole frame.

[0006] The effects achieved by the above components are as follows: By setting the adjusting device, first manually move the two wheel chock bodies. When the two wheel chock bodies move to the front and rear positions of the aircraft tire, make the round hole frame fit the ground. At this time, manually press the round hole frame and manually rotate the operation block, so that the operation block drives the bidirectional screw to rotate along the inside of the round hole frame, so that the bidirectional screw drives the two screw hole blocks to move towards each other, so that the two screw hole blocks drive the two wheel chock bodies to move towards each other. When the two wheel chock bodies move towards each other to the position where they simultaneously fit the surface of the aircraft tire, the two wheel chock bodies respectively block the front and rear positions of the aircraft tire, thereby completing the rapid blocking of the aircraft tire, reducing the situation that the wheel chock body does not fit the surface of the aircraft tire when personnel place it, and improving the convenience and efficiency of using the wheel chock body.

[0007] Preferably, a plurality of anti-slip strips are fixedly connected to the surface of the operation block, and the plurality of anti-slip strips are arranged at equal distances.

[0008] The effect achieved by the above components is that by setting the anti-slip strips, the anti-slip strips can increase the friction between the hand and the surface of the operation block, and reduce the situation of hand slipping when manually rotating the operation block.

[0009] Preferably, baffles are fixedly connected to both sides of the bidirectional screw away from the round hole frame, and the surface of the baffle is larger than the inner wall of the screw hole block.

[0010] The effect achieved by the above components is that by setting the baffles, the baffles can intercept the screw hole block during the moving process, and reduce the situation of the screw hole block detaching from the surface of the bidirectional screw.

[0011] Preferably, an anti-slip bottom plate is fixedly connected to one side of the round hole frame, and a plurality of anti-slip protrusions are provided on the surface of the anti-slip bottom plate.

[0012] The effect achieved by the above components is that by setting the anti-slip bottom plate, the anti-slip bottom plate can increase the contact area and friction between the round hole frame and the ground, improve the use stability of the round hole frame, and at the same time reduce the situation of the round hole frame sliding.

[0013] Preferably, round hole blocks are fixedly connected to one side of the two screw hole blocks, and two positioning rods are symmetrically and fixedly connected to the surface of the round hole frame. The surfaces of the two positioning rods are respectively slidably connected to the inner walls of the two round hole blocks.

[0014] The effect achieved by the above components is that by setting the positioning rods and the round hole blocks, the positioning rods can be located inside the round hole blocks to intercept and limit the screw hole blocks and the wheel block body, and reduce the situation of shaking when the bidirectional screw drives the screw hole blocks to move.

[0015] Preferably, the auxiliary device includes a circular groove opened on one side of the wheel block body. A circular rod is slidably connected to the inner wall of the circular groove. A rectangular rod is fixedly connected to one side of the circular rod. A spring is provided inside the circular groove. One end of the spring is fixedly connected to the circular rod, and the other end of the spring is fixedly connected to the inner wall of the circular groove.

[0016] The effect achieved by the above-mentioned components is as follows: by setting up the auxiliary device, first, under the expansion and contraction action of the spring, the spring drives the round rod to move toward the inside of the circular groove, so that the round rod drives the rectangular rod to move toward the direction close to the wheel chock body, thereby achieving automatic recovery of the rectangular rod; when the wheel chock body needs to be moved, the rectangular rod is manually pulled, so that the rectangular rod cooperates with the round rod to drive the wheel chock body to move, thereby achieving convenient movement of the wheel chock body, reducing the lack of fulcrums on the wheel chock body, causing people to slip when manually moving the wheel chock body, causing the wheel chock body to fall and be damaged, and improving the convenience and stability of people carrying or moving the wheel chock body.

[0017] Preferably, the surface of the rectangular rod is covered with a rubber sleeve, and the surface of the rubber sleeve is provided with a plurality of protrusions.

[0018] The effect achieved by the above components is: by arranging the rubber sleeve, the rubber sleeve can increase the contact resistance between the manual hand and the rectangular rod, and reduce the situation of hand slipping when manually moving the rectangular rod.

At this time, manually press the round hole frame 21 and manually rotate the operating block 23, so that the operating block 23 drives the bidirectional screw 22 to rotate along the inside of the round hole frame 21, so that the bidirectional screw 22 drives the two screw hole blocks 28 to move towards each other, so that the two screw hole blocks 28 drive the two wheel chock bodies 1 to move towards each other. When the two wheel chock bodies 1 move towards each other to the position where they simultaneously fit the surface of the aircraft tire, make the two wheel chock bodies 1 respectively block the front and rear positions of the aircraft tire, thus completing the rapid blocking of the aircraft tire, reducing the situation that the wheel chock body does not fit the surface of the aircraft tire when personnel place the wheel chock body, and improving the use convenience and efficiency of the wheel chock body 1.

[0029] Refer to Figure 2 and Figure 3 As shown in the figure, this embodiment discloses that a plurality of anti-slip strips 24 are fixedly connected to the surface of the operating block 23.

When the two wheel chock bodies 1 move towards each other to the position where they are simultaneously in contact with the surface of the aircraft tire, the two wheel chock bodies 1 respectively block the front and rear positions of the aircraft tire, thereby completing the rapid blocking of the aircraft tire. At the same time, when the aircraft tire accidentally moves, the sensor 4 detects its position and emits a sound or light to the outside, giving an alarm prompt to the staff outside.

[0034] First, under the telescopic action of the spring 35, the spring 35 drives the round rod 33 to move towards the inside of the round groove 31, and the round rod 33 drives the rectangular rod 34 to move towards the wheel chock body 1, thereby achieving the automatic retraction of the rectangular rod 34. When it is necessary to move the wheel chock body 1, manually pull the rectangular rod 34, so that the rectangular rod 34 cooperates with the round rod 33 to drive the wheel chock body 1 to move, thereby achieving the convenient movement of the wheel chock body 1.
