Description

Technical Field

[0001] This utility model relates to the field of pull-out electrical cabinet technology, and in particular to a pull-out electrical cabinet for signal equipment used in subways. Background Technology

[0002] As an efficient and high-capacity public transportation system, the subway not only effectively alleviates urban traffic pressure, shortens commuting time, and improves residents' quality of life, but also enhances the city's image, reflects its technological level and comprehensive strength, and is an important symbol of urban modernization. The subway brings together diverse people, records urban changes, and becomes a carrier of culture and spirit. However, the increasing number of people choosing the subway for travel has led to overcrowding. To further improve the public transportation experience for citizens, subway trains are becoming increasingly intelligent and automated, resulting in a growing number of electrical components in the train control system. However, the space available for installing these components and equipment inside the subway car is limited. Against this backdrop, it is necessary to utilize every possible space to install electrical components. This utility model's electrical cabinet allows the signal cabinet inside to be pulled out, and electrical components can be arranged on the side of the signal cabinet, reducing the pressure on equipment installation and wiring. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a pull-out electrical cabinet for signal devices used in subways, which can pull the entire signal cabinet out of the electrical cabinet, so that the electrical components arranged on the side of the signal cabinet are clearly visible, which facilitates inspection and maintenance, reduces maintenance costs, makes reasonable use of space, and effectively alleviates the pressure of insufficient installation space for electrical components.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a pull-out electrical cabinet for a signal device used in a subway, comprising an outer frame, a tray, a first L-shaped bracket, a second L-shaped bracket, a first slide rail, a second slide rail, a third slide rail, a sliding bracket, and a sliding support.

[0005] The bottom of the outer frame is fixedly equipped with two or more crossbeams;

[0006] The first L-shaped bracket and the second L-shaped bracket are fixed on the crossbeam. The tray is slidably connected to the first L-shaped bracket via the first slide rail, and the tray is slidably connected to the second L-shaped bracket via the second slide rail.

[0007] The tray has a bearing surface that matches the bottom profile of the signal device;

[0008] A sliding bracket is fixedly installed on one side of the upper part of the outer frame, and the sliding bracket is slidably connected to the sliding bracket through a third slide rail;

[0009] The sliding bracket is fixedly connected to the signal device.

[0010] Furthermore, a metal frame is provided inside the outer frame, and the metal frame is embedded in the tray.

[0011] Furthermore, at least two pins are fixedly installed at the pull-out end of the tray.

[0012] Furthermore, a press lock is provided on the first slide rail and the second slide rail.

[0013] Furthermore, a mounting bracket or mounting plate is provided on one side of the outer frame for mounting electrical components.

[0014] Furthermore, a handle is also fixedly provided on the pull-out end of the tray.

[0015] Furthermore, a handle for dragging is provided at the top of the metal frame.

[0016] Through the above design scheme, this utility model can bring the following beneficial effects: Since most signal cabinets weigh more than 100kg, most signal cabinets are currently fixedly installed inside the electrical cabinet. Unless for maintenance or modification, the signal cabinet will not be moved, resulting in serious waste of space around the signal cabinet. Therefore, the existing solution can no longer meet the operational needs. This utility model is a pull-out electrical cabinet for signal cabinets. High load-bearing slide rails are used to pull the entire signal cabinet out of the electrical cabinet. In this way, the electrical components on the side of the signal cabinet are fully visible, which is very convenient for inspection and maintenance, reduces maintenance costs, and makes reasonable use of space.

[0024] The present invention will now be described in further detail with reference to specific embodiments. However, this should not be construed as limiting the scope of protection of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0025] like Figure 1-5 As shown, this embodiment provides a pull-out electrical cabinet for signal devices used in subways, including an outer frame 1, a tray 2, a first L-shaped bracket 3, a second L-shaped bracket 4, a first slide rail 5, a second slide rail 6, a third slide rail 7, a sliding bracket 8, and a sliding support 9.

[0026] Among them, the first slide rail 5, the second slide rail 6 and the third slide rail 7 are high load-bearing slide rails, and the slide rail length and slide rail stroke are completely consistent.

[0027] The bottom of the outer frame 1 is fixedly provided with two or more crossbeams 10;

[0028] The first L-shaped bracket 3 and the second L-shaped bracket 4 are fixed on the crossbeam 10. The tray 2 is slidably connected to the first L-shaped bracket 3 via the first slide rail 5, and the tray 2 is slidably connected to the second L-shaped bracket 4 via the second slide rail 6.

[0029] The tray 2 has a bearing surface that matches the bottom profile of the signal device;

[0030] A sliding bracket 8 is fixedly installed on one side of the upper part of the outer frame 1, and the sliding bracket 8 is slidably connected to the sliding bracket 9 through the third slide rail 7;

[0031] The sliding bracket 9 is fixedly connected to the signal device.

[0032] Furthermore, a metal frame 11 is provided inside the outer frame 1, and the metal frame 11 is embedded in the tray 2.

[0033] Furthermore, at least two pins 12 are fixedly installed at the pull-out end of the tray 2.

[0034] Furthermore, a press lock 13 is provided on the first slide rail 5 and the second slide rail 6.

[0035] Furthermore, a mounting bracket or mounting plate is provided on one side of the outer frame 1 for mounting electrical components.

[0036] Furthermore, a handle 14 is fixedly installed on the pull-out end of the tray 2. Because the signal device is relatively heavy, carbon steel reinforcing ribs are welded to the bottom of the tray 2 to reduce the deformation when the signal device cabinet is pulled out.

[0037] Furthermore, the top of the metal frame 11 is also provided with a handle for dragging.

[0038] This invention places the signal cabinet on a tray 2. A first slide rail 5 and a second slide rail 6 are installed on the front and rear sides of the tray 2, respectively. The two bottom slide rails have built-in limiters, but because the signal cabinet is relatively heavy, two pins 12 are used for secondary limiters to prevent it from breaking through the limiters due to inertia during subway operation. A third slide rail 7 is also used on the upper side to facilitate pulling out the signal cabinet. In use, the pins 12 are rotated 90 degrees and pulled upwards to the fixed position. Then, the push lock 13 of the slide rail is pressed, and the signal cabinet can be pulled out using the handle 14 for easy inspection and maintenance of the side electrical components.

[0039] On the inner side after the signal is pulled out, there is a mounting bracket or mounting plate for arranging electrical components. This makes reasonable and effective use of space, reduces the pressure of component arrangement, and facilitates maintenance, saving costs and time.
