Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary maintenance devices for electrical construction, and in particular to a mobile maintenance device. Background Technology

[0002] During the installation and commissioning of electrical work, workers inevitably encounter situations where the electrical equipment is installed at a height higher than themselves. When inspecting and maintaining electrical equipment at heights that are higher than the workers' height, auxiliary maintenance devices are needed. Workers can use these auxiliary maintenance devices, such as A-frame ladders, to raise their height so that they can inspect and maintain electrical equipment at high locations.

[0003] When inspecting electrical equipment at multiple heights, lateral adjustments are inevitable. Existing mobile maintenance devices, such as A-frame ladders, require workers to move them laterally, which necessitates repeated climbing, significantly impacting work efficiency and convenience, and causing inconvenience to staff. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a mobile maintenance device that can effectively improve work efficiency and convenience, and bring convenience to staff.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mobile maintenance device, comprising a base, a lateral movement mechanism, and a drive mechanism. The lateral movement mechanism includes a moving frame. Two sets of convex connecting plates are symmetrically fixedly connected to the top of the base, and two sets of guide columns are symmetrically fixedly connected between the two sets of convex connecting plates. Two sets of guide plates are symmetrically fixedly mounted on the moving frame, and the two sets of guide plates are slidably fitted onto the two sets of guide columns. Two sets of wheel axles are symmetrically fixedly mounted at the lower front and rear ends of the moving frame, and moving wheels are rotatably mounted on all four sets of wheel axles. The wheels are all supported on the base. Multiple sets of crossbars are symmetrically and equidistantly arranged on the mobile frame. The drive mechanism includes a motor, which is fixedly installed on the top inner side of the mobile frame. A horizontal plate is fixedly connected to the bottom of the mobile frame. A transmission worm is rotatably installed on the horizontal plate. The output end of the motor is fixedly connected to the top of the transmission worm. A transmission shaft is rotatably installed on the lower inner side of the mobile frame. A worm wheel is fixedly sleeved in the middle of the transmission shaft. The worm wheel meshes with the transmission worm. Two sets of gears are symmetrically fixedly sleeved on the transmission shaft. Two sets of racks are symmetrically fixedly installed on the base. The two sets of gears mesh with the two sets of racks respectively.

[0007] Preferably, the movable frame is equipped with two sets of handrails fixedly at both the front and rear ends, symmetrically.

[0008] Preferably, storage boxes are fixedly connected to the upper sides of both the left and right ends of the mobile frame.

[0009] Preferably, an anti-slip pad is fixedly connected to the top of the mobile frame.

[0010] Preferably, a reinforcing rod is fixedly connected between the outer side of both sets of convex connecting plates and the top of the base.

[0011] Preferably, four sets of anti-slip pads are fixedly connected to the bottom of the base, and the four sets of anti-slip pads are distributed at the four corners of the bottom of the base.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, workers can step on the horizontal bar to adjust their height according to the position of the electrical equipment. Furthermore, disassembled electrical equipment can be placed on the top of the mobile frame to serve as a maintenance platform. When horizontal movement is required, the motor is started, driving the transmission worm gear to rotate. The worm gear, through meshing with the worm wheel, drives the transmission shaft to rotate clockwise. The transmission shaft, through the meshing of the gear and rack, moves the mobile frame to the right, and vice versa. Guided by the guide plate and guide column, the mobile frame moves smoothly. The mobile frame drives the moving wheels to roll on the base, providing support. This ensures that the gear and rack only mesh, preventing the gear from pressing on the rack. Thus, workers no longer need to repeatedly climb, effectively improving work efficiency and convenience, and bringing convenience to the workers. Attached Figure Description

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0019] Example

[0020] Please see Figures 1-4 This utility model discloses a mobile maintenance device, comprising a base 1, with two sets of convex connecting plates 3 symmetrically fixedly connected to the top of the base 1, and two sets of guide columns 4 symmetrically fixedly connected between the two sets of convex connecting plates 3. Two sets of guide plates 5 are symmetrically fixedly mounted on the mobile frame 2, and the two sets of guide plates 5 are slidably fitted onto the two sets of guide columns 4. Two sets of wheel axles 6 are symmetrically fixedly mounted at the lower front and rear ends of the mobile frame 2, and four sets of moving wheels 7 are rotatably mounted on each of the four sets of wheel axles 6. All four sets of moving wheels 7 are supported on the base 1. Multiple sets of crossbars 8 are symmetrically and equidistantly arranged on the front and back of the mobile frame 2. A motor 9 is fixedly installed on the top inner side of the mobile frame 2. A horizontal plate 10 is fixedly connected to the bottom of the mobile frame 2. A transmission worm gear 11 is rotatably mounted on the horizontal plate 10. The output end of the motor 9 is fixedly connected to the top end of the transmission worm gear 11. A transmission shaft 12 is rotatably mounted on the lower inner side of the mobile frame 2. A worm wheel 13 is fixedly sleeved in the middle of the transmission shaft 12, meshing with the transmission worm gear 11. Two sets of gears 14 are symmetrically fixedly sleeved on the transmission shaft 12. Two sets of gears 14 are symmetrically fixedly mounted on the base 1. The system consists of two sets of racks 15 and two sets of gears 14 meshing with each other. During use, workers can step on the crossbar 8 to adjust their height according to the location of the electrical equipment. Disassembled electrical equipment can also be placed on top of the mobile frame 2 as a maintenance platform. When horizontal movement is required, the motor 9 is started, driving the transmission worm gear 11 to rotate. This worm gear 11, through meshing with the worm wheel 13, drives the transmission shaft 12 to rotate clockwise. The transmission shaft 12, through meshing with the gears 14 and racks 15, moves the mobile frame 2 to the right, and vice versa. Guided by the guide plate 5 and guide column 4, the mobile frame 2 moves smoothly. The mobile frame 2 drives the moving wheels 7 to roll on the base 1, supporting the mobile frame 2 and ensuring that there is only meshing between the gears 14 and racks 15, preventing the gears 14 from pressing on the racks 15. This eliminates the need for repeated climbing, effectively improving work efficiency and convenience.

[0021] The mobile frame 2 is symmetrically equipped with two sets of handrails 16 at both the front and rear ends. By setting the handrails 16, the staff can hold onto the handrails 16 when climbing, which makes it easier to grip the handrails and improves the safety of climbing.

[0022] Storage boxes 17 are fixedly connected to the upper sides of both the left and right ends of the mobile frame 2. By setting up storage boxes 17, when workers climb onto the mobile frame 2 to perform maintenance operations, they can temporarily place the tools they need in the storage boxes 17 for easy access at any time.

[0023] The top of the mobile frame 2 is fixedly connected to an anti-slip pad 18; by setting the anti-slip pad 18, the friction on the top of the mobile frame 2 can be increased, so that it is not easy for workers to slip when standing on the mobile frame 2 or for electrical equipment to be placed.

[0024] Both sets of convex connecting plates 3 are fixedly connected to the outer side of the base 1 and the top of the base 1 with reinforcing rods 19; by setting reinforcing rods 19, the connection between the convex connecting plates 3 and the base 1 can be made more firm and stable.

[0025] The base 1 is fixedly connected to four sets of anti-slip rubber pads 20, which are distributed at the four corners of the bottom of the base 1. By setting the anti-slip rubber pads 20, the base 1 is less likely to slip on the placement surface when it is placed.

[0026] This utility model discloses a mobile maintenance device. In operation, workers can step on the horizontal bar 8 to adjust their height according to the location of the electrical equipment. Disassembled electrical equipment can be placed on the top of the mobile frame 2 as a maintenance platform. When lateral movement is required, the motor 9 is started, driving the transmission worm gear 11 to rotate. The worm gear 11, through meshing with the worm wheel 13, drives the transmission shaft 12 to rotate clockwise. The transmission shaft 12, through meshing with the gear 14 and rack 15, moves the mobile frame 2 to the right, and vice versa. Guided by the guide plate 5 and guide column 4, the mobile frame 2 moves smoothly. The mobile frame 2 drives the mobile wheels 7 to roll on the base 1, supporting the mobile frame 2. This ensures that the gear 14 and rack 15 are only meshed, preventing the gear 14 from pressing on the rack 15, thus eliminating the need for repeated climbing by the workers.

[0027] The mobile maintenance device of this utility model uses common mechanical methods for installation, connection, or setting. Any method that can achieve the desired beneficial effect can be implemented. The motor of the mobile maintenance device of this utility model is purchased from the market. Technical personnel in this industry only need to install and operate it according to the accompanying instruction manual.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
