Description

Technical Field

[0001] This utility model relates to the field of power operation and maintenance technology, and in particular to a safety relocation device for high-voltage switchgear trolleys. Background Technology

[0002] When maintaining high-voltage switchgear, it is necessary to move the trolley. Traditionally, this is done manually or by pushing a simple cart. Existing relocation devices are usually kept horizontal with the trolley, requiring force to pull it out. This method requires considerable strength and is prone to tipping over during movement, posing a safety hazard. While some devices can assist in movement, they do not simplify the retrieval process and still rely on manual operation. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where most moving devices maintain the trolley at a horizontal position, requiring manual pulling to remove the trolley. Therefore, this invention proposes a safe moving device for high-voltage switchgear trolleys.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-voltage switchgear trolley safety relocation device includes a relocation trolley body, a tray for placing the trolley is provided on the upper side of the relocation trolley body via four lifting wheels, and movable wheels are fixed at the four corners of the bottom of the relocation trolley body;

[0006] The tray has two first grooves, and each of the two first grooves has a track plate that allows the trolley's moving wheels to slide. The two track plates and the two first grooves respectively form guide grooves, and the trolley's moving wheels on both sides are respectively located in the two guide grooves.

[0007] To facilitate the opening or closing of the guide slot, an adjustment assembly is provided on the underside of the tray. The adjustment assembly is used to drive the two track plates to adjust their angle, thereby opening or closing the guide slot.

[0008] In one possible design, the adjustment assembly includes a first mounting plate and a second mounting plate fixed to the bottom of the tray. Two limiting rods are fixed between the first mounting plate and the second mounting plate. The surfaces of the two limiting rods are slidably provided with the same threaded plate. Sliding columns are fixed at both ends of the threaded plate. Connecting blocks are fixed at the bottom ends of the two track plates. Sliding grooves are opened in the two connecting blocks. The two sliding columns slide in the two sliding grooves respectively.

[0009] The mechanism involves moving a threaded plate, which in turn moves two sliding columns. As the two columns move outward, they slide within a groove, causing the connecting block to shift relative to the track plate. This causes the track plate to flip away from the first groove, forming a guide groove. At this point, pulling the trolley outward causes the wheels on the trolley to move into the inclined track plate. The trolley can then be easily removed using its own weight. Moving the two sliding columns inward causes the connecting block to shift upward relative to the track plate, returning it to the first groove. This keeps the track plate and the tray level, making it easier to push the trolley back into the switch cabinet.

[0010] In one possible design, the adjustment assembly further includes a lead screw that rotates between a first mounting plate and a second mounting plate. The outer wall of the lead screw is fitted with a slider that engages with a helical groove of the lead screw. The slider is fixed inside a threaded plate. The lead screw moves outward through the side end of the second mounting plate and is fixed with a handle.

[0011] The screw is rotated by turning the handle, which makes it easy to control the position movement of the threaded plate, and it can maintain self-locking after movement.

[0012] In one possible design, the tops of both track plates are polished.

[0013] In one possible design, a limit post is fixed to the top of the tray to limit the movement of the handcart.

[0014] In one possible design, a push handle is fixed to the side of the tray.

[0015] In this application, the screw is rotated by turning the handle, which facilitates the position movement of the threaded plate and maintains self-locking after movement.

[0016] The threaded plate is moved by a drive mechanism, which in turn moves two sliding columns. As the two columns move outward, they slide within a groove, causing relative displacement of the connecting block. This drives the track plate away from the first groove and flips to form a guide groove. At this point, pulling the trolley outward causes its wheels to move into the inclined track plate. The trolley's own weight allows for easier removal. Moving the two sliding columns inward then drives the connecting block upward, causing relative displacement of the track plate back into the first groove. This keeps the track plate and tray level, facilitating the pushing of the trolley back into the switch cabinet.

[0017] Beneficial effects: In this utility model, the high-voltage switchgear trolley safety shifting device achieves safe loading and unloading by adjusting the angle of the track plate and utilizing the trolley's own weight, thus avoiding the risks of manual lifting;

[0018] In this utility model, the safety shifting device for the high-voltage switchgear trolley, with its guide groove and track plate design, ensures smooth shifting of the trolley and reduces jamming. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In one embodiment: Refer to Figures 1-3 The relocation device includes a relocation vehicle body 1, a tray 3, and an adjustment assembly. The relocation vehicle body 1 has a rectangular frame structure, with four casters 2 bolted to its four corners for easy overall movement. The tray 3 is mounted on the upper side of the relocation vehicle body 1 via four lifting casters 6, which can adjust the height of the tray 3 to accommodate different switch cabinet heights.

[0025] Two first grooves 4 are formed on the surface of the tray 3, and a track plate 5 is rotatably installed in each first groove 4 via a rotating shaft. The track plate 5 is an L-shaped metal plate, and its top is polished to reduce friction. When the track plate 5 is horizontal, it forms a guide groove with the side wall of the first groove 4, and the moving wheels on both sides of the handcart are respectively embedded in the two guide grooves to achieve lateral limitation;

[0026] The adjustment assembly includes a first mounting plate 8, a second mounting plate 9, a lead screw 12, and a threaded plate 10. The first mounting plate 8 and the second mounting plate 9 are fixed to the bottom of the tray 3 by bolts, and two limiting rods 11 are welded between them. A through hole is formed on the surface of the threaded plate 10, and the limiting rods 11 pass through the through hole to achieve sliding guidance.

[0027] The lead screw 12 is rotatably mounted on the first mounting plate 8 and the second mounting plate 9 via bearings at both ends. A helical groove is machined on its outer wall, engaging with a slider embedded in the threaded plate 10. The outer end of the lead screw 12 passes through the second mounting plate 9 and is welded with a handle 13.

[0028] A connecting block 7 is welded to the bottom of the track plate 5, and an inclined groove 14 is formed inside the connecting block 7. Sliding columns 15 are welded to both ends of the threaded plate 10, and the sliding columns 15 are embedded in the groove 14.

[0029] During operation, rotating the handle 13 clockwise drives the lead screw 12 to rotate, causing the threaded plate 10 to move outward along the limit rod 11, which in turn causes the slide column 15 to slide within the slide groove 14, forcing the connecting block 7 to move down and flip the track plate 5, thus opening the guide groove; rotating the handle 13 counterclockwise resets the track plate 5 to a horizontal state, closing the guide groove.

[0030] In another embodiment: Reference Figures 1-3 The high-voltage switchgear trolley safety relocation device is used in the field of power operation and maintenance technology. Four limiting posts 16 are welded to the top of the tray 3 and distributed at the four corners of the trolley to prevent the trolley from slipping during relocation. Push handles 17 are welded to the sides of the tray 3 and covered with anti-slip rubber to facilitate pushing by the operator.

[0031] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
