Description

Technical Field

[0001] This invention belongs to the field of subway power distribution system maintenance technology, and in particular relates to a gantry for removing power distribution cabinets. Background Technology

[0002] Subway lines require numerous electrical distribution cabinets for operation. These cabinets house many electrical components to ensure the stable operation of the subway power system. To save space, multiple distribution cabinets in the subway control room are often arranged in rows, forming distribution cabinet groups. When an inner distribution cabinet needs inspection or maintenance, it is usually manually lifted out before the operation can be performed. Since subway line maintenance can only be carried out during specific evening hours, time constraints are very tight. The current method of manually lifting the distribution cabinet is time-consuming, labor-intensive, and also carries certain risks. Therefore, it is necessary to design a device that facilitates the removal of distribution cabinets. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and proposes a gantry for removing power distribution cabinets.

[0004] To achieve the above objectives, the technical solution created by this invention is implemented as follows:

[0006] Each support frame has a sleeve at its top end, and the sleeves on the two support frames are arranged at the same height. Both ends of the crossbeam are inserted into the corresponding sleeves and are detachably connected to the corresponding sleeves through connectors. The sliding frame includes two parallel seat plates. A top pulley is provided between the two seat plates on the upper side of the crossbeam, and a bottom pulley is provided between the two seat plates on the lower side of the crossbeam. An elongated hole is provided on at least one seat plate, and several fixing holes are provided at intervals on the crossbeam. The height of each fixing hole corresponds to the elongated hole on the seat plate. Lifting holes are symmetrically arranged on the lower side of the two seat plates.

[0007] Furthermore, several bottom reinforcing plates are provided between the base frame and the foundation frame.

[0008] Furthermore, several top reinforcing plates are provided between the sleeve and the top frame.

[0009] Furthermore, the surface of the seat plate facing the crossbeam is provided with a PTFE plate.

[0010] Furthermore, the connector is made of bolts.

[0011] Furthermore, the base frame has an extension frame fixing position corresponding to the extension frame, and the extension frame has a top frame fixing position corresponding to the top frame.

[0012] Furthermore, the expansion frame fixing position includes an expansion frame fixing groove, an expansion frame positioning pin is provided in the expansion frame fixing groove, and the expansion frame is provided with several expansion frame positioning holes of different heights.

[0013] Furthermore, the top frame fixing position includes a top frame fixing groove, a top frame positioning pin is provided at the top frame fixing groove, and the extension frame is provided with several top frame positioning holes of different heights.

[0014] Compared with existing technologies, the present invention has the following advantages:

[0015] This invention features a rationally designed structure. The gantry frame can be easily moved across the top of the distribution cabinet, making it simple to use and saving time and effort. By installing an electric hoist on the lifting hole on the lower side of the sliding frame, the distribution cabinet is lifted off the ground. Then, the distribution cabinet to be repaired is pushed to move it horizontally out of the assembled distribution cabinets. After that, the gantry frame is pushed out by aligning the distribution cabinets.

[0026] A type of gantry frame for removing power distribution cabinets, such as Figures 1 to 5 As shown, it includes two symmetrically arranged support frames 1, with a crossbeam 2 between the two support frames, and a sliding frame 3 slidably mounted on the crossbeam; the support frame includes a base frame 4 and a foundation frame 5 on the base frame, an extension frame 6 is installed at the upper end of the foundation frame with adjustable height, a top frame 7 is installed at the upper end of the extension frame with adjustable height, and symmetrically arranged traveling wheels 8 at the lower part of the base frame; each support frame has a sleeve 9 at the upper end of the top frame, and the sleeves on the two support frames are arranged at the same height.

[0027] In an optional embodiment, the crossbeam adopts a telescopic structure, specifically including a base beam 20 and an extension beam 21 inserted into the base beam. The base beam is provided with a fastener for fixing the extension beam. By loosening the fastener, the length of the extension beam extending beyond the base beam can be easily adjusted to accommodate the needs of distribution cabinets of different widths or thicknesses. After adjusting the extension beam to the desired position, it can be relocked using the fastener.

[0029] The sliding frame includes two parallel seat plates 10. A top pulley 11 is located between the two seat plates on the upper side of the crossbeam, and a bottom pulley 12 is located between the two seat plates on the lower side of the crossbeam. An elongated hole 13 is provided on at least one seat plate. Several fixing holes 14 are spaced apart on the crossbeam, and the height of each fixing hole corresponds to the elongated hole on the seat plate. Lifting holes 15 are symmetrically arranged on the lower side of the two seat plates. It should be noted that the lifting holes in the attached drawings are only schematic representations, and the size and shape of the lifting holes can be designed according to actual needs.

[0030] Preferably, the surface of the seat plate facing the crossbeam is provided with a PTFE plate to increase the lubrication between the sliding frame and the crossbeam and prevent jamming. The PTFE plate is detachably installed on the inside of the seat plate and can be replaced according to the wear condition.

By installing an electric hoist on the lifting hole on the lower side of the sliding frame, the distribution cabinet is lifted off the ground. Then, the distribution cabinet to be repaired is pushed to move it horizontally out of the distribution cabinet group. After that, the gantry frame is pushed out by moving the distribution cabinet group horizontally.
