[0009] In this utility model, the limiting high chassis vehicle maintenance teaching auxiliary device includes a limiting structure and a pad structure symmetrically arranged on both sides of the limiting structure.

[0010] Each of the pad structures includes a support and a pad block. The pad block is inserted and fixed along the vertical direction of the support. The end of the pad block away from the ground is an inclined end, and the lower inclined end is the end away from the support and is flush with the ground. A lifting plate is provided on the support. The lifting plate is installed on the support by a driving component. The driving component controls the lifting plate to move up or down in the vertical direction.

[0011] The lifting plate lifts the vehicle tires through an arc-shaped concave shape.

[0012] The limiting structure includes an auxiliary block, on which multiple limiting grooves are formed, and the opening direction of each limiting groove is consistent with the length direction of the vehicle when it is being lifted.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] This application provides a limited-position high-chassis vehicle maintenance teaching auxiliary device, which solves the problem in the prior art where, when trainees lie flat on a trolley to maintain high-chassis vehicles, the trolley operated by the trainees deviates significantly due to the trainees' lack of practical experience. This achieves efficient teaching of high-chassis vehicle maintenance.

[0034] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0035] Example:

[0036] like Figures 1-3 As shown, a limiting type high chassis vehicle maintenance teaching auxiliary device includes a limiting structure 2 and a pad structure 1 symmetrically arranged on both sides of the limiting structure 2.

[0037] Each of the pad structures 1 includes a support 10 and a pad block 11. The pad block 11 is inserted and fixed along the vertical direction of the support 10. The end of the pad block 11 away from the ground is an inclined end, and the lower inclined end is the end away from the support 10 and flush with the ground. A lifting plate 102 is provided on the support 10. The lifting plate 102 is installed on the support 10 by a driving member 101. The driving member 101 controls the lifting plate 102 to move up or down in the vertical direction.

[0038] The lifting plate 102 lifts the vehicle tires through the arc-shaped recess 103;

[0039] The limiting structure 2 includes an auxiliary block 20, on which a plurality of limiting grooves 21 are provided, and the opening direction of each limiting groove 21 is consistent with the length direction of the vehicle when it is being lifted.

[0040] A movable structure 3 is installed on the limiting structure 2. The movable structure 3 slides along the limiting groove 21 to the vehicle's maintenance position via pulleys.

[0041] Specifically, the two pad structures 1 are located on both sides of the limiting structure 2 and are installed and fixed to the ground in a detachable manner. The detachable manner is achieved by using ground bolts for detachable fixing, so as to limit the limiting structure 2 and the two pad structures 1 during use.

[0042] Specifically, the fixed end of the driving component 101 is fixedly connected to the support 10, and the moving end of the driving component 101 is fixedly connected to the lifting plate 102, controlling the lifting plate 102 to move vertically upward or downward.

[0043] Specifically, the mobile structure 3 is a mobile flatbed vehicle. The maintenance personnel lie flat on the mobile flatbed vehicle, and the mobile flatbed vehicle slides to the bottom of the high chassis vehicle through the limiting groove 21 for maintenance.

[0044] By setting the auxiliary teaching device in the form of a limiting structure 2 and two pad structures 1, the front of the vehicle is lifted by the two pad structures 1, and the angle of the lifting of the front of the vehicle is controlled by the drive component 101, so as to facilitate the maintenance operation of the maintenance personnel.

[0045] Meanwhile, the setting of the limiting structure 2 can realize the limiting of the moving structure 3 during the movement process, which makes it easy to control the moving structure 3 to drive the maintenance personnel to the maintenance position. This solves the problem that in the current teaching process, when students lie flat on the trolley to maintain high chassis vehicles, due to the students' lack of practical experience, the trolley operated by the students deviates significantly, making it difficult to accurately control the trolley to reach the chassis to be maintained position, resulting in low teaching efficiency for high chassis vehicle maintenance.

[0046] It should be noted that the maintenance teaching aid in this application is used when the teacher teaches each component of the chassis of a high-chassis vehicle to the whole class of students one by one, and each student needs to practice one by one. It overcomes the problem that students' learning efficiency in high-chassis vehicle maintenance teaching is low within the limited class time, making it difficult to complete the teaching task within the limited class time.

[0047] like Figures 1-2 As shown, the inclined end of the pad 11 has a hollow opening, and multiple triangular steps 112 are arranged in the hollow opening, with a gap 111 formed between two adjacent triangular steps 112.

[0048] Each of the aforementioned triangular steps 112 is welded to the pad block 11;

[0049] Each of the triangular steps 112 has one edge that contacts the wheel passing over the pad 11.

[0050] By setting multiple triangular steps 112 on the pad block 11, the vehicle tires are limited by the multiple triangular steps 112, thereby increasing the stability of the tires when they slide on the inclined end of the pad block 11.

[0051] like Figure 1 As shown, a rubber pad 12 is provided at the bottom of the pad structure 1. The rubber pad 12 increases the friction between the pad structure 1 and the ground, thereby further improving the stability of the pad structure 1 after it is installed on the ground.

[0052] Specifically, the rubber pad 12 is bonded to the ground of the pad structure 1;

[0053] Alternatively, a protrusion can be provided on the rubber pad 12, and a corresponding recess can be provided at the bottom of the pad structure 1. The corresponding limiting of the protrusion and the recess can be used to achieve the initial limiting of the rubber pad 12 and the pad structure 1.

[0054] like Figure 3 As shown, a storage cart 30 is provided on the movable structure 3, and the storage cart 30 slides along the slotting direction of the limiting groove 21 via pulleys;

[0055] The storage cart 30 is fixed to the movable structure 3 at one end near the movable structure 3.

[0056] Specifically, the storage cart 30 can be fixed to the movable structure 3 by welding.

[0057] By setting up a storage cart 30 on the side of the mobile structure 3, and placing conventional tools for maintenance inside the storage cart 30, maintenance personnel can access the tools for maintenance and complete the teaching work on the maintenance of high chassis vehicles.

[0058] When working, first, place the limiting structure 2 on the floor of the high chassis vehicle maintenance training room;

[0059] Next, the pad 11 is inserted and assembled into pad structure 1 along the vertical direction of support 10, and the rubber pad 12 is installed at the bottom of pad structure 1. The two assembled pad structures 1 are then symmetrically placed on both sides of limiting structure 2.

[0060] The limiting structure 2 and the two pad structures 1 together form a teaching auxiliary device for high chassis vehicle maintenance, which is used to assist in the practical operation of high chassis vehicle maintenance teaching and meet the needs of efficient classroom teaching.

[0061] After the auxiliary device is placed, the wheels on both sides of the high chassis vehicle used for teaching slide along the pads 11 on the two pad structures 1 until the wheels move along the pads 11 into the arc-shaped recess 103 for a limit.

[0062] During the training, the lifting range of the vehicle's front end is controlled by the drive component 101. While the drive component 101 adjusts the lifting range of the front end, other lifting devices are needed to lift the vehicle's front end. The assistance of the lifting device can further prevent the front end from falling off the lifting plate 102 and improve the safety of the maintenance process after the front end is lifted. The lifting device can be any existing lifting device and is not the protection point of this application, so it will not be described in detail here.

[0063] Then, the maintenance personnel lie flat on the movable structure 3 with their upper bodies, and use their leg strength to move the movable structure 3 and the storage cart 30 fixed to the movable structure 3 to the maintenance position to carry out the corresponding maintenance teaching task.

[0064] It should be noted that, in practical applications, it has been found that extending the side of the limiting structure 2 closest to the pad structure 1 beyond the length of at least one moving structure 3 of the pad structure 1 is necessary. Specifically, as shown below... Figure 4 As shown, this design allows maintenance personnel to lie flat on the movable structure 3, so that they can slide to the corresponding maintenance location using the movable structure 3.

[0065] In summary, compared with existing technologies, it has the following beneficial effects:

[0066] 1. By setting the auxiliary teaching device in the form of a limiting structure 2 and two pad structures 1, the front of the vehicle is lifted by the two pad structures 1, and the angle of the lifting of the front of the vehicle is controlled by the driving component 101, so as to facilitate the maintenance operation of the maintenance personnel.

[0067] Meanwhile, the setting of the limiting structure 2 can realize the limiting of the moving structure 3 during the movement process, which makes it easy to control the moving structure 3 to drive the maintenance personnel to the maintenance position. This solves the problem that in the current teaching process, when students lie flat on the trolley to maintain high chassis vehicles, due to the students' lack of practical experience, the trolley operated by the students deviates significantly, making it difficult to accurately control the trolley to reach the chassis to be maintained position, resulting in low teaching efficiency for high chassis vehicle maintenance.

[0068] 2. By setting up a storage cart 30 on the side of the mobile structure 3, and placing conventional tools for maintenance inside the storage cart 30, maintenance personnel can access the tools for maintenance and complete the teaching work of high chassis vehicle maintenance.
