[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides a technical solution, please refer to Figure 1 and Figure 2 An electrical maintenance and repair vehicle includes: a base 1, a scissor lift platform 2, a load-bearing plate 3, and a fence 4. The scissor lift platform 2 is mounted on the upper end of the base 1, and the load-bearing plate 3 is mounted on the upper end of the scissor lift platform 2. The fence 4 is mounted on the upper end of the load-bearing plate 3. The right side of the fence 4 is designed with an opening, and a side plate 5 is connected to the right side of the fence 4 by a hinge. A roller 51 is connected to the inside of the side plate 5 by a bearing with a seat. Limiting arms 52 are connected to both sides of the left side of the side plate 5. Limiting mechanisms 6 are mounted on both sides of the inside of the fence 4.

[0026] The base 1 supports the scissor lift platform 2, which is a common lifting device in the prior art. It is used to drive the fence 4 to lift. The load-bearing plate 3 supports the fence 4. The fence 4 prevents workers and workpieces from falling from the top of the load-bearing plate 3. The side plate 5 can close the fence 4. At the same time, the roller 51 facilitates the feeding and unloading of materials. The limiting arm 52 can fix the position of the side plate 5.

[0027] Please see Figure 3 , Figure 4 and Figure 5 The limiting mechanism 6 includes a gear 61, and a first rack 62 and a second rack 63 are respectively meshed on both sides of the gear 61. The second rack 63 is T-shaped, and hollow columns 64 are evenly distributed on the top of the second rack 63. A trapezoidal block 65 is slidably connected to the top of the hollow column 64. A spring is connected between the trapezoidal block 65 and the hollow column 64. The first rack 62 is inserted into the bottom of the fence 4.

[0028] The gear 61 can drive the first rack 62 and the second rack 63 to move up and down by rotating. The first rack 62 can be pushed up by the base 1 when the fence 4 is lowered. The second rack 63 can drive the hollow column 64 and the trapezoidal block 65 to move. The trapezoidal block 65 can retract into the hollow column 64. The cooperation between the trapezoidal block 65 and the hollow column 64 allows the limiting arm 52 to be inserted into the fence 4, but it cannot return to its original position.

[0029] The fence 4 has a slot, and the inside of the slot is connected to a door panel 41 by a hinge. The door panel 41 facilitates the entry of workers into the inside of the fence 4. Both sides of the inside of the fence 4 have L-shaped slots 42. The inside of the L-shaped slots 42 is connected to a gear 61 by a seated bearing. The L-shaped slots 42 facilitate the assembly of the limiting mechanism 6.

[0030] The second rack 63 is externally connected to a slider 67, and the slider 67 is externally slidably connected to a slotted block 66. The slotted block 66 is connected to the L-shaped groove 42. A first spring 68 is connected between the slider 67 and the slotted block 66. The slotted block 66, in conjunction with the slider 67, can guide the second rack 63 to move linearly. When the fence 4 rises, the first spring 68 can pull the second rack 63 to rise and return to its original position, and at the same time drive the first rack 62 to return to its original position through the gear 61.

[0031] The bottom of the limiting arm 52 is evenly provided with grooves that are slidably connected to the trapezoidal block 65, and the limiting arm 52 is connected to the fence 4 through a track hinge. The grooves facilitate the insertion of the trapezoidal block 65, thereby fixing the position of the limiting arm 52. The bottom of the base 1 is evenly provided with casters 11, and there are at least four sets of casters 11. The casters 11 facilitate the movement of the base 1.

[0032] This solution first drives the scissor lift platform 2 to return the fence 4 to its original position. At this time, the first rack 62 inside the fence 4 is pushed up by the top of the base 1, which then drives the gear 61 to rotate. This drives the second rack 63, hollow column 64 and trapezoidal block 65 to descend, releasing the fixation of the limiting arm 52. The side plate 5 is then pushed so that it contacts the ground. Workers can use the roller 51 to push goods into the inside of the fence 4 for collection. Then the side plate 5 is returned to its original position, and the scissor lift platform 2 is started to lift the fence 4. At this time, the first rack 62 returns to its original position by gravity, driving the second rack 63 to rise, which drives the trapezoidal block 65 to engage inside the limiting arm 52, thus restricting the position of the side plate 5.

[0033] During electrical maintenance and repair, the added side plate 5 and roller 51 facilitate the quick placement of maintenance tools and workpieces inside the enclosure 4 for collection, avoiding the inability to drive quickly due to the excessive size and weight of the workpieces. At the same time, the added limiting mechanism 6 can quickly lock and unlock the side plate 5 according to the working status of the enclosure 4, thereby improving the overall intelligence of the device and making it convenient for staff to use.
