Description

Technical Field

[0001] This utility model relates to the field of DC cabinet technology for rail transit, specifically a height-adjustable trolley slide. Background Technology

[0002] With the popularization of urban rail transit, rail transit travel is becoming increasingly popular, and the application of DC switchgear will become more and more widespread.

[0003] Currently, through on-site surveys within the traction substations, it has been found that the floor height of each station is different, making it difficult for maintenance personnel to push the handcart into the cabinet. Forcibly pushing the handcart would damage the cabinet's anti-rust coating and insulation board. Therefore, there is an urgent need for a height-adjustable handcart slide. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable height trolley slide to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adjustable height trolley slide, including a column, a height plate, a movable plate, an extension plate, a screw, a hinge, and a flat plate. The column, flat plate, and screw are welded and fixed. The height plate and movable plate are riveted together by the hinge. Both the extension plate and movable plate have oblong holes. The extension plate is fitted onto the screw through the oblong holes and is clamped and fixed by nuts. The height plate has hexagonal holes on both sides. Bolts pass through the hexagonal holes to fix the height plate to the column. The column has oblong holes for the height plate to move up and down. Both the height plate and movable plate have round holes adapted to the screw. The height plate and movable plate are fitted onto the screw through the corresponding round holes and are clamped and fixed by nuts.

[0006] Preferably, the height plate can move up and down along the elongated oval hole on the column.

[0007] Preferably, the movable plate is rotatable about the hinge.

[0008] Preferably, the extension plate is movable along the screw and its own elongated oval hole.

[0009] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0010] This utility model can precisely adapt to the ground height of different sites by moving the height plate up and down along the long oval hole of the column, adjusting the angle of the movable plate around the hinge, and adjusting the extension plate along the screw and its own long oval hole. This ensures that the slope angle of the handcart's pushing path is gentle, eliminating the need to forcibly push the handcart, greatly reducing the difficulty of operation and maintenance, and preventing damage to the anti-rust coating and insulation board of the cabinet when the handcart is pushed into the cabinet. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the overall structure of this utility model.

[0012] The components include: 1. uprights; 2. height plate; 3. movable plate; 4. extension plate; 5. screw; 6. hinge; 7. flat plate. Detailed Implementation

[0013] 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.

[0014] This utility model provides the following technical solution:

[0015] Please see Figure 1 An adjustable height trolley slide includes a column 1, a height plate 2, a movable plate 3, an extension plate 4, a screw 5, a hinge 6, and a flat plate 7. The column 1 is welded and fixed to the flat plate 7 and the screw 5. The height plate 2 and the movable plate 3 are riveted together by the hinge 6. Both the extension plate 4 and the movable plate 3 have oblong holes. The extension plate 4 is fitted onto the screw 5 through the oblong holes and is clamped and fixed by nuts. The height plate 2 has hexagonal holes on both sides. Bolts pass through the hexagonal holes to fix the height plate 2 to the column 1. The column 1 has oblong holes for the height plate 2 to move up and down. Both the height plate 2 and the movable plate 3 have round holes that match the screw 5. The height plate 2 and the movable plate 3 are fitted onto the screw 5 through the corresponding round holes and are clamped and fixed by nuts.

[0016] The height plate 2 can move up and down along the elongated oval hole on the column 1.

[0017] The movable plate 3 can rotate around the hinge 6.

[0018] The extension plate 4 can move along the screw 5 and its own elongated oval hole.

[0019] Through the above technical solution, the column 1 is welded and fixed to the plate 7 and the screw 5. The height plate 2 and the movable plate 3 are riveted and installed with hinges 6. The extension plate 4 and the movable plate 3 each have an oblong hole, which is fixed to the screw 5 and clamped with nuts. The height plate 2 has hexagonal holes on both sides, which are fixed to the column 1 with bolts. At the same time, the circular holes on the height plate 2 and the movable plate 3 are installed on the screw 5 and clamped with nuts. Since the height plate 2 is fixed in the oblong hole of the column 1 with screws, it can move up and down. The movable plate 3 is connected to the height plate 2 with hinges 6, which can be adjusted according to the height and angle. The extension plate 4 and the movable plate 3 share a stud for fixing, which can be extended and shortened according to the height to ensure a gentle slope angle. When the height is adjusted to meet the current site's ground requirements, the height plate 2 is tightened to the column 1 and the screw 5, and the upper and lower nuts of the screw 5 to the height plate 2, the movable plate 3, and the extension plate 4 are tightened. In this way, the entire trolley slide is adjusted and the trolley can be easily pushed into the cabinet.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
