[0041] like Figure 1 As shown, this embodiment provides a maintenance auxiliary trolley, including a support base 1 and a protective frame 2. The bottom of the support base 1 is provided with movable rollers 11. The protective frame 2 is elastically supported on the support base 1 by an elastic component. The protective frame 2 is used to carry workpieces. The protective frame 2 has a loaded state with workpieces and an unloaded state with workpieces unloaded, so that the elastic component has a compressed state and a reset state. When the protective frame 2 is in the loaded state, the movable rollers 11 and the protective frame 2 are simultaneously supported on the ground. When the protective frame 2 is in the unloaded state, the movable rollers 11 are supported on the ground, and there is a gap between the protective frame 2 and the ground.

[0042] When the protective frame 2 is under load, it supports and protects the workpiece. At this time, the moving roller 11 and the protective frame 2 support the ground simultaneously, which can provide relatively stable support for the workpiece, prevent the workpiece and maintenance trolley from tipping over, and reduce safety risks. When the protective frame 2 is unloaded, there is a gap between the protective frame 2 and the ground. The moving roller 11 supports the ground and moves the maintenance trolley to the required position. The maintenance trolley can ensure stability during maintenance and can also be moved when unloaded.

[0043] In this embodiment, the protective frame 2 is made of channel steel, making it sturdy and durable. In other embodiments, the protective frame 2 is not limited to channel steel and can be made of other materials, as long as they meet the usage requirements.

[0044] Optionally, the protective frame 2 includes a protective base 21 and protective railings 22. The protective base 21 is elastically supported on the support base 1 by an elastic component. Protective railings 22 are provided on opposite sides of the protective base 21. The protective frame 2 supports the protective railings 22 through the protective base 21 and is elastically supported on the support base 1 through the protective base 21. The protective railings 22 can support the workpiece and prevent it from tipping over.

[0045] Optionally, the protective frame 2 also includes a connecting frame 23, which connects the two sets of protective railings 22. The connecting frame 23 enhances the stability of the protective frame 2.

[0046] Optionally, the protective frame 2 also includes a reinforcing frame 24. Reinforcing frames 24 are provided on both sides of the protective railing 22. One end of the reinforcing frame 24 is connected to the protective railing 22, and the other end is connected to the protective base frame 21. The reinforcing frame 24, the protective railing 22, and the protective base frame 21 form a triangular structure. This structure provides good stability for the protective frame 2.

[0047] Furthermore, the protective base frame 21 includes a base frame body 211 and support legs 212. The base frame body 211 is elastically supported on the support base 1 by an elastic component, and the protective railing 22 is disposed on the base frame body 211. The support legs 212 are disposed on the side of the base frame body 211, and the support legs 212 can support the ground or have a gap with the ground. The base frame body 211 is used to support the protective railing 22, and the support legs 212 are disposed on the side of the base frame body 211, and can support the ground through the support legs 212, thus playing a supporting role.

[0048] In this embodiment, the support base 1 is a rectangular structure, and the base frame body 211 is also a rectangular structure. Protective railings 22 are provided at both ends of the base frame body 211 along its length direction. The support base 1 extends out from both sides of the base frame body 211. Support feet 212 are located on the outside of the support base 1. Each of the four top corners of the base frame body 211 is provided with a support foot 212. The bottom surface of the support foot 212 is lower than the bottom surface of the base frame body 211. When the protective frame 2 is under the gravity of the workpiece, the support foot 212 can be stably supported on the ground.

[0049] Furthermore, the base frame body 211 includes an outer frame 2111 and support plates 2112 disposed within the outer frame 2111. The outer frame 2111 is a rectangular frame, and the support feet 212 are disposed at the bottom of the outer frame 2111. The support plates 2112 extend along the width direction of the rectangular frame. In this embodiment, two sets of support plates 2112 are provided, and the two sets of support plates 2112 are arranged at intervals along the length direction of the rectangular frame, thereby enhancing the support strength of the base frame body 211. In other embodiments, the number of sets of support plates 2112 is not limited to two sets, but may be one set, three sets, or more sets, which is not specifically limited here.

[0050] Optionally, the support base 1 is provided with multiple sets of limiting guide members 12, and the support plate 2112 is limited between each set of limiting guide members 12. The protective frame 2 can move along the height direction of the limiting guide members 12 to avoid movement in other directions.

[0051] In this embodiment, a limiting guide 12 is provided on the side of the two sets of support plates 2112 that are away from each other. The installation position of the protective frame 2 is limited by the limiting guide 12. Moreover, the limiting guide 12 extends in the vertical direction. The setting of the limiting guide 12 makes the protective frame 2 only able to move in the height direction (vertical direction) of the limiting guide 12, so as to avoid the protective frame 2 from being deviated in position.

[0052] When two or more sets of support plates 2112 are provided, the limiting guide 12 can be located on the side opposite to each other of any two sets of support plates 2112; when one set of support plates 2112 is provided, the limiting guide 12 can be located on opposite sides of the support plates 2112, which can also play the role of limiting and guiding.

[0053] like Figure 1 As shown, the elastic component includes multiple elastic elements 3, and the protective frame 2 is elastically mounted on the support base 1 via the multiple elastic elements 3. The elastic mounting of the protective frame 2 on the support base 1 via the multiple elastic elements 3 facilitates the elastic installation of the protective frame 2 on the support base 1.

[0054] In this embodiment, elastic elements 3 are provided at the four top corners of the support base 1, which can make the protective frame 2 more stable during elastic movement and avoid the phenomenon of the protective frame 2 tilting.

[0055] It should be noted that the elastic element 3 is a built-in spring sleeve, and its structure is existing technology, so it will not be described in detail here.

[0056] In this embodiment, the movable roller 11 is a swivel wheel, which allows for easy adjustment of the travel direction of the maintenance assistance trolley, thus facilitating its movement.

[0057] Optionally, the maintenance assistance trolley also includes a pusher 13, which is connected to the support base 1, and the pusher 13 facilitates the movement of the maintenance assistance trolley.

[0058] In this embodiment, the maintenance auxiliary trolley is used when the C-hook is being repaired. When the protective frame 2 carries the C-hook, the protective frame 2 supports the C-hook and prevents it from tipping over. The elastic element 3 between the protective frame 2 and the support base 1 is compressed, and the support foot 212 and the moving roller 11 of the protective frame 2 are simultaneously supported on the ground, which can provide relatively stable support for the C-frame and prevent the C-frame and the maintenance auxiliary trolley from tipping over. When the protective frame 2 is unloaded, the elastic element 3 returns to its original position, the protective frame 2 rises, and the support foot 212 of the protective frame 2 leaves the ground. At this time, only the moving roller 11 is in contact with the ground, and the moving roller 11 facilitates the movement of the trolley.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
