[0003] Currently, the maintenance of the upper components of automated equipment is relatively mature. However, since the lower equipment is in contact with the ground, inspection and maintenance usually require lifting the entire lower equipment using forklifts or other equipment before operators can inspect it. However, lifting the lower equipment as a whole carries the risk of it falling, posing a certain safety hazard.

[0004] Therefore, it is necessary to propose a vehicle that can ensure the safety of the working environment to solve the above problems. Utility Model Content

[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] like Figure 1 As shown, this utility model embodiment provides a trolley for equipment inspection and maintenance, including a frame 10, a bracket 20, and an electric lifting assembly 30; the frame 10 includes an upper frame 101 and a lower frame 102, the bracket 20 includes a first bracket 201 and a second bracket 202 that are rotatably connected, and the electric lifting assembly 30 includes a motor 301, a reducer 302, and a lead screw 303. The reducer 302 is connected to the output end of the motor 301, and the lead screw 303 is connected to the output end of the reducer 302; wherein, the upper frame 101 and the lower frame 102 each have corresponding openings in the opposite side frames along the length direction at the same end. A sliding groove 103 is provided, in which the two ends of the top rod of the first support 201 and the two ends of the bottom rod of the second support 202 are slidably connected to the upper frame 101 and the lower frame 102 respectively. The two ends of the bottom rod of the first support 201 and the two ends of the top rod of the second support 202 are fixed in the frames on opposite sides of the lower frame 102 and the upper frame 101 along the length direction respectively. The motor 301 and the reducer 302 are fixed at one end of the lower frame 102, and the lead screw 303 is set along the length direction of the lower frame 102. The bottom rod of the second support 202 is provided with a movable block 40, the two ends of which are connected through the lead screw 303.

[0035] When in use, the bottom device 90 is placed on the upper frame 101, and the motor 301 and reducer 30 are started to drive the lead screw 303 to rotate, so that the movable block 40 moves linearly on the lead screw 303, thereby causing the movable block 40 to drive the second bracket 202 to rotate relative to the first bracket 201, so as to achieve the purpose of raising and lowering the bottom device 90.

[0036] The trolley used for equipment inspection and maintenance supports the bottom equipment 90 through the frame 10 and bracket 20, reducing the risk of the equipment falling and ensuring the safety of the operator's working environment.

[0037] In actual use, to prevent the bottom device 90 on the upper frame 101 from falling off, such as Figures 2-3 As shown, the upper frame 101 has second sliding grooves 1011 on the top of opposite sides along its length. A fixing member 50 is slidably connected within the second sliding groove 1011, securing the bottom device 90 and further ensuring the stability of the device. Additionally, the top of the upper frame 101 has anti-slip textured surfaces, effectively preventing the bottom device 90 from sliding on the upper frame 101.

[0038] Specifically, the fixing member 50 includes a screw 501 and a nut 502 adapted to the screw 501. The screw 501 is slidably connected to the second slide groove 1011. In this embodiment, there are four screws 501 and four nuts 502, with two nuts 502 on each of the second slide grooves 1011. In use, the screw 501 is slid to both ends of the bottom device 90, and then the screw 501 is fixed by the nut 502, thereby limiting the position of the bottom device 90.

[0039] More specifically, nut 502 is a wing nut to facilitate the operator in loosening and tightening nut 502.

[0040] Generally speaking, equipment maintenance needs to be carried out on the maintenance platform. In order for the trolley to bring the bottom equipment 90 to the maintenance platform, the bottom of the lower frame 102 is equipped with casters 60.

[0041] Specifically, the caster wheel 80 is equipped with a brake to facilitate the movement and fixation of the trolley.

[0042] To facilitate the operator in pushing the trolley, a platform 1021 extends from one end of the lower frame 102. A support rod 70 is provided on the platform 1021, and a pusher 80 is provided on the support rod 70.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
