Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet installation technology, and more specifically to an installation device for power distribution cabinets. Background Technology

[0002] A distribution cabinet is a core piece of equipment in a power system that uses components such as circuit breakers, contactors, relays, and transformers to work together to achieve power distribution, circuit protection, control, and monitoring. Essentially, it is a "power transportation hub" that ensures the safe and accurate delivery of power to every load through hierarchical protection, intelligent control, and real-time feedback. It is widely used in industrial, commercial, and residential applications.

[0003] The installation quality of distribution cabinets directly affects the safety and stability of the power system. In the installation scenario of long rows of large distribution cabinets, horizontal calibration is a key step to ensure the safe and stable operation of the power distribution system. If the cabinet is not calibrated, it may lead to problems such as mechanical stress, poor electrical contact, uneven heat dissipation, and even affect the life of the equipment.

[0004] The leveling of power distribution cabinets usually involves placing the first power distribution cabinet in place, and then using tools such as a level and laser to measure the front and back, left and right levels to ensure overall accuracy before reinforcement. This calibration process requires the use of auxiliary tools for positioning and calibration, and the operation steps are complicated.

[0005] Therefore, the inventors propose an installation device for a power distribution cabinet that combines handling and calibration. Summary of the Invention

[0006] In response to the problems raised in the background art, the present invention provides an installation device for a power distribution cabinet to solve them, and the present invention will be further described below.

Detailed Implementation

[0022] Next, we will combine the appendix Figure 1 -Appendix Figure 5 A specific embodiment of the present invention will be described in detail below.

[0023] Reference Appendix Figures 1-5 An installation device for a power distribution cabinet includes a transport frame 1, on which a sliding frame 13 is slidably connected. Two symmetrically distributed support plates 18 are slidably connected to the sliding frame 13. The two support plates 18 interlock to form a single plate structure. The power distribution cabinet to be installed is supported by the two support plates 18. To facilitate the transportation of the power distribution cabinet to be installed to its destination, casters are installed on the transport frame 1.

[0024] As described in the background technology, in the parallel installation of multiple distribution cabinets, horizontal calibration is a crucial step to ensure the safe and stable operation of the power distribution system. Horizontal calibration aims to prevent the distribution cabinet from tilting, which can lead to mechanical stress deformation after long-term operation, affecting the normal operation of the distribution cabinet. At the same time, the internal components of the distribution cabinet generate a lot of heat during operation. If it is tilted, it will cause uneven distribution of hot air, local overheating and affecting the service life. Conventional calibration usually uses a level to check the levelness of the cabinet. This method requires relevant personnel to check the front and back, left and right levelness of the cabinet, and then the cabinet is adjusted and fixed in place with bolts. The calibration efficiency is low. Based on this, this device improves the calibration efficiency by using a calibration component.

[0025] refer to Figure 1 , Figure 3, Figure 4 The calibration assembly includes an electric slide rail 2 mounted on a transport frame 1. Two symmetrically distributed sliders 21 slide on the electric slide rail 2. Each slider 21 is connected to a limit rod 23. The two sliders 21 drive the limit rods 23 to move. The purpose is twofold: first, to limit the position of the distribution cabinet on the support plate 18 by means of the two limit rods 23, so as to prevent the distribution cabinet from swaying left and right when the transport frame 1 moves; and second, to calibrate the distribution cabinet to be installed and the previous distribution cabinet by means of the two limit rods 23.

[0026] The transport frame 1 is equipped with two symmetrically distributed telescopic components 26. Each telescopic end of the telescopic component 26 is provided with a guide frame 25. The guide frame 25 is provided with a groove (not shown in the figure). The limiting rod 23 is provided with a flange 33. The limiting rod 23 and the guide frame 25 are stably connected by the groove and the flange 33 engaging.

[0027] The distribution cabinet to be installed is placed on the support plate 18. The transport frame 1 is moved to the destination. The groove and flange 33 are engaged. The limiting rod 23 is stably connected to the guide frame 25. According to the position of the previous distribution cabinet, the slider 21 is adjusted. The limiting rod 23 is moved in a controlled manner. That is, the front end of the two limiting rods 23 is positioned on the left and right sides of the previous distribution cabinet. The distribution cabinet to be installed is clamped between the two limiting rods 23. As the limiting rods 23 move, the guide frame 25 moves in a controlled manner. The telescopic end of the telescopic component 26 extends. Based on the two limiting rods 23, the distribution cabinet to be installed is aligned with the left and right sides of the previous distribution cabinet.

[0028] In order to improve the alignment effect between the distribution cabinet to be installed and the previous distribution cabinet, that is, to improve the calibration accuracy of this device and avoid errors, the following settings are made: multiple triggers 3 are slidably connected to the limiting rod 23, each trigger 3 is provided with a wedge 32, a tension spring 31 is compressed between the trigger 3 and the limiting rod 23, and a limiting frame 24 is slidably connected to the limiting rod 23, which is intended to limit the front and rear of the distribution cabinet through the transport frame 1 and the limiting frame 24 to prevent the distribution cabinet from tilting forward and backward.

[0029] refer to Figure 4 A linear spring 34 is compressed between the limiting frame 24 and the limiting rod 23. The limiting frame 24 has pin holes 241 corresponding to the number of trigger elements 3. Each pin hole 241 is fitted with a second pin 35. That is, the pin hole 241 and the second pin 35 form a positioning pin mechanism. The second pin 35 passes through the pin hole 241 and is engaged with the guide frame 25.

[0030] Initially, the second pin 35 engages with the pin hole 241, the linear spring 34 is in a compressed state, and the limit bracket 24 is stable on the guide bracket 25.

[0031] The inclined block 32 on the trigger 3 can be pressed and engaged with the second pin 35 to release the positioning pin of the second pin 35. The key point is that the inclined block 32 on the trigger 3 of this device simultaneously applies equal force and distance to the second pin 35, and only then does the second pin 35 push upward and disengage from the pin hole 241. This determines the complete calibration effect between the power distribution cabinet to be installed and the previous power distribution cabinet. Otherwise, there is a calibration deviation, which forms a foolproof structure. Only under the condition of complete calibration will the second pin disengage.

[0032] As explained above, the front ends of the two limiting rods 23 are positioned on the left and right sides of the front distribution cabinet. Adjusting the slider 21, the limiting rods 23, the trigger 3, and the limiting frame 24 move synchronously under control. The distribution cabinet to be installed is clamped between the two limiting rods 23. At this time, the trigger 3 contacts the distribution cabinet to be installed and generates pressure. There are two possible scenarios: First, if the distribution cabinet to be installed and the front distribution cabinet are aligned on both sides, multiple triggers 3 slide simultaneously, and the inclined block 32 on the trigger 3 interacts with the second pin 35. When pressure is applied, the second pin 35 is simultaneously pushed up, disengaging from the pin hole 241 and being pushed upwards. Due to the presence of the linear spring 34, the limit frame 24 slides, thus the device completes calibration. Secondly, the left and right sides of the distribution cabinet to be installed and the front distribution cabinet are not aligned. The inclined block 32 on the trigger 3 exerts different forces on the second pin 35, preventing the second pin 35 from disengaging from the pin hole 241. The second pin 35 and the limit frame 24 do not move, thus indicating that there is a calibration deviation and adjustment is required.

[0033] After calibration, the distribution cabinet to be installed needs to be detached from the transport frame 1 and installed at the target location in its original calibrated position. Therefore, the following settings are made: an electric push rod 12 is connected to the transport frame 1 via a fixing member 11. The output shaft of the electric push rod 12 is fixedly connected to the sliding frame 13. The sliding frame 13 is connected to two bearing plates 18 via two pairs of distributed support rod assemblies 14. The purpose is that by the action of the electric push rod 12, in conjunction with the action of the sliding frame 13, the two support rod assemblies 14 can be retracted and extended, thereby connecting the two bearing plates 18 to support the distribution cabinet, or the two bearing plates 18 can slide in opposite directions to allow the distribution cabinet to fall to its original calibrated position.

[0034] Before calibration, the two support rod assemblies 14 are retracted, the two bearing plates 18 are connected, and the distribution cabinet to be installed is placed on the two bearing plates 18. After calibration, the second pin 35 is pushed upward and disengaged from the pin hole 241. The electric push rod 12 is activated, the sliding frame 13 moves down, and the two bearing plates 18 and the distribution cabinet to be installed on them move down in conjunction with each other. The purpose is to lower the center of gravity of the distribution cabinet to be installed so that it can fall smoothly from the bearing plate 18.

[0035] As the sliding frame 13 moves down, the two support rod assemblies 14 move in opposite directions, that is, the two support rod assemblies 14 open up, causing the two bearing plates 18 to slide apart in opposite directions, and the power distribution cabinet falls. To further ensure the stability of the power distribution cabinet falling, each of the bearing plates 18 is provided with an inclined surface, which is intended to allow the power distribution cabinet to fall at a low position along the inclined surface as the support rod assemblies 14 open up and the two bearing plates 18 separate.

[0036] refer to Figure 5 The support plate 18 is also provided with ball bearings 181 and rollers 182, which are designed to facilitate the sliding of the support plate 18 relative to the distribution cabinet.

[0037] The transport frame 1 is connected to two symmetrically distributed guide plates 17 via a rotating shaft 171. Specifically, the rotating shaft 171 is rotatably connected to the transport frame 1, and the guide plates 17 are fixed to the rotating shaft 171. The two guide plates 17 are distributed on the left and right sides of the transport frame 1 and are connected to the adjacent support plate 18. The purpose of the two guide plates 17 is to connect the support plate 18 to the ground, so as to facilitate the movement of the power distribution cabinet onto the support plate 18. The power distribution cabinet to be installed moves along the guide plates 17 onto the support plate 18. In order to facilitate the smooth movement of the power distribution cabinet to be installed on the guide plates 17, the guide plates 17 are also provided with ball bearings 181, which are intended to reduce the friction between the guide plates 17 and the power distribution cabinet to be installed.

[0038] refer to Figure 2 Each guide plate 17 is fixedly connected to a straight rod 172, and each straight rod 172 is provided with a first pin 19. The bearing plate 18 is provided with a locking hole 183, which engages with the first pin 19. The purpose of the locking hole 183 and the first pin 19 is to achieve a stable positioning effect for the guide plate 17. A gear 16 is fixedly connected to the rotating shaft 171. A rack 15 is provided on the sliding frame 13. The rack 15 meshes with the gear 16. A protrusion 131 is also provided on the sliding frame 13. The protrusion 131 presses against the side of the guide plate 17 to limit the rotation angle of the guide plate 17.

[0039] As the sliding frame 13 moves downward, the rack 15 moves downward in a controlled manner. The rack 15 meshes with the gear 16, the rotating shaft 171 rotates, and the linkage guide plate 17 and the straight rod 172 rotate synchronously until the side of the guide plate 17 touches the protrusion 131 and remains stationary. The first pin 19 engages with the locking hole 183, and the guide plate 17, the straight rod 172 and the bearing plate 18 form a stable semi-enclosed triangular structure.

[0040] During the process of the distribution cabinet to be installed falling to its original calibrated position, the stable semi-enclosed triangular structure formed by the guide plate 17, the straight rod 172 and the bearing plate 18, as well as the trigger 3 and the limit rod 23, protect the distribution cabinet to be installed and prevent it from tipping over during the falling process.

[0041] Specifically, before the calibration operation, in order to facilitate the smooth movement of the distribution cabinet to be installed onto the support plate 18, the limiting rod 23 should be positioned out of place. During the calibration operation, the limiting rod 23 should be kept in a clamping state on the distribution cabinet to be installed. Based on this, the following settings are made: the transport frame 1 is provided with two symmetrically distributed compression frames 22. The compression frames 22 are distributed on both sides of the transport frame 1 and are provided with wedge blocks. The positioning effect is achieved by the compression cooperation between the limiting rod 23 and the wedge blocks of the compression frames 22.

[0042] The two sliders 21 move in opposite directions, and the two limiting rods 23 move in a controlled manner. The groove on the guide frame 25 engages with the flange 33 on the limiting rod 23, and the guide frame 25 moves in a controlled manner. The telescopic end of the telescopic member 26 extends until the limiting rod 23 presses against the wedge block of the extrusion frame 22. The limiting rod 23 moves upward along the wedge block of the extrusion frame 22, and the flange 33 on the limiting rod 23 and the groove on the guide frame 25 disengage. Then, the limiting rod 23 moves upward smoothly, removing the obstruction to the distribution cabinet to be installed and achieving the positioning effect. The distribution cabinet to be installed can then be smoothly moved from the guide plate 17 to the bearing plate 18. Subsequently, the two sliders 21 move in opposite directions, and the two limiting rods 23 move in a controlled manner. The groove on the guide frame 25 engages with the flange 33 on the limiting rod 23 again, and the guide frame 25 and the limiting rod 23 form a stable structure, allowing the above calibration action to be performed.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
