Description

Technical Field

[0001] The present invention relates to the technical field of distribution cabinet installation, and particularly relates to an installation device for a distribution cabinet. Background Art

[0002] A distribution cabinet is a core device in a power system that realizes power distribution, circuit protection, control, and monitoring through the coordinated operation of components such as circuit breakers, contactors, relays, and current transformers. Its essence is a "power transportation hub" that ensures the safe and accurate transmission of electrical energy to each load through hierarchical protection, intelligent control, and real-time feedback, and is widely used in industrial, commercial, residential, and other places.

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

[0004] For the horizontal calibration of the distribution cabinet, usually the first distribution cabinet is placed in position, and then tools such as a spirit level and a laser level are used to measure the front-back and left-right levels. After ensuring the overall accuracy, it is reinforced. During this calibration process, auxiliary tools are needed for positioning and calibration, and the operation steps are complicated.

Detailed implementation manners

[0022] Next, a specific embodiment of the present invention will be elaborated in detail with reference to the attached Figure 1 - attached Figure 5 drawings.

[0023] Referring to the attached Figures 1 - 5 drawings, an installation device for a power distribution cabinet includes a transport rack 1, on which a sliding frame 13 is slidably connected. Two symmetrically distributed bearing plates 18 are slidably connected to the sliding frame 13. The two bearing plates 18 are concavely and convexly interlocked to form an integral plate structure. The power distribution cabinet to be installed is received by the two bearing plates 18. To facilitate the transportation of the power distribution cabinet to be installed to the destination, universal wheels are installed on the transport rack 1.

[0024] According to the background technology, in the parallel installation of multiple power distribution cabinets, horizontal calibration is a key step to ensure the safe and stable operation of the power distribution system. The purpose of horizontal calibration is to prevent the power distribution cabinet from tilting, which may cause mechanical stress deformation after long-term operation and affect the normal operation of the power distribution cabinet. At the same time, when the internal components of the power distribution cabinet are operating, they generate a large amount of heat. If tilted, it will lead to uneven distribution of hot air and local overheating, affecting the service life. Conventional calibration usually uses a level to detect the levelness of the cabinet body. This method requires relevant personnel to detect the front, rear, left, and right levelness of the cabinet body, and then fix the position with bolts after adjusting the cabinet body. The calibration efficiency is low. Based on this, the present device improves the calibration efficiency through a calibration assembly.

[0025] Referring to Figure 1 , Figure 3, Figure 4 , the calibration assembly includes an electric slide rail 2 installed on the transport rack 1. Two symmetrically distributed sliders 21 are slidably connected to the electric slide rail 2. Limit rods 23 are rotatably connected to the sliders 21. The two sliders 21 drive the limit rods 23 to move. The purposes are as follows: one is to use the two limit rods 23 to limit the power distribution cabinet on the bearing plate 18 to prevent the power distribution cabinet from shaking left and right when the transport rack 1 moves; the other is to calibrate the power distribution cabinet to be installed and the previous power distribution cabinet through the two limit rods 23.

[0026] Two symmetrically distributed telescopic members 26 are installed on the transport rack 1. Guide frames 25 are provided at the telescopic ends of the telescopic members 26. A sinking groove (not shown in the figure) is provided on the guide frame 25. A flange 33 is provided on the limit rod 23. The stable connection between the limit rod 23 and the guide frame 25 is realized through the clamping fit between the sinking groove and the flange 33.

[0027] The power distribution cabinet to be installed is placed on the bearing plate 18. The transport rack 1 is moved to the destination. The sinking groove is matched with the flange 33, and the limit rod 23 is stably connected to the guide frame 25. According to the position of the previous power distribution cabinet, the slider 21 is adjusted, and the limit rod 23 is controlled to move. That is, the front ends of the two limit rods 23 are positioned on the left and right sides of the previous power distribution cabinet. The power distribution cabinet to be installed is clamped between the two limit rods 23. As the limit rod 23 moves, the guide frame 25 is controlled to move, and the telescopic end of the telescopic member 26 extends. Based on the two limit rods 23, the effect of aligning the left and right sides of the power distribution cabinet to be installed with the previous power distribution cabinet is realized.

[0028] In the above, in order to improve the alignment effect of the power distribution cabinet to be installed and the previous power distribution cabinet, that is, to improve the calibration accuracy of the device and avoid errors, the following settings are made: A plurality of trigger members 3 are slidably connected to the limit rod 23. Inclined blocks 32 are provided on the trigger members 3. Tensile springs 31 are compressed between the trigger members 3 and the limit rod 23. A limit frame 24 is slidably connected to the limit rod 23, aiming to limit the front and back of the power distribution cabinet through the transport rack 1 and the limit frame 24 to prevent the power distribution cabinet from tipping forward and backward.

[0029] Reference Figure 4 , a linear spring 34 is compressed between the limit frame 24 and the limit rod 23. Pin holes 241 corresponding to the number of trigger members 3 are formed on the limit frame 24. Second pins 35 are fitted in the pin holes 241 respectively. That is, the pin holes 241 and the second pins 35 constitute a positioning pin mechanism, and the second pins 35 penetrate through the pin holes 241 and are clamped on the guide frame 25.

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

[0031] The cam 32 on the trigger 3 can be in extrusion fit with the second pin 35 to achieve the effect of releasing the locating pin of the second pin 35. The key point is that the cam 32 on the trigger 3 of this device simultaneously exerts an equal-force and equal-distance extrusion on the second pin 35, and only then will the second pin 35 jack up and disengage from the pin hole 241. From this, it can be determined whether the switchgear to be installed is fully aligned with the previous switchgear. Otherwise, there will be a calibration deviation, that is, an anti-fooling structure is formed. Only when fully calibrated, the second pin can be disengaged.

[0032] As described above, the front ends of the two limit rods 23 are positioned on the left and right sides of the previous switchgear. By adjusting the sliding block 21, the limit rods 23, the trigger 3, and the limit frame 24 move synchronously and are controlled. The switchgear to be installed is clamped between the two limit rods 23. At this time, the trigger 3 contacts the switchgear to be installed and generates extrusion. There are the following two judgment situations: First, if the switchgear to be installed is aligned with the left and right sides of the previous switchgear, multiple triggers 3 slide simultaneously, and the cams 32 on the triggers 3 exert the same force on the second pins 35. The second pins 35 jack up synchronously, and the second pins 35 disengage from the pin holes 241 and jack up. Due to the existence of the linear spring 34, the limit frame 24 slides. From this, it can be obtained that the calibration of this device is completed. Second, if the left and right sides of the switchgear to be installed and the previous switchgear are not aligned, the cams 32 on the triggers 3 exert different forces on the second pins 35. The second pins 35 cannot disengage from the pin holes 241, and the second pins 35 and the limit frame 24 do not move. Therefore, it can be determined that there is a calibration deviation and adjustment is required again.

[0033] After calibration, the switchgear to be installed needs to be detached from the transport rack 1 and installed in place at the target location according to the calibrated position. Therefore, the following settings are made: An electric push rod 12 is connected to the transport rack 1 through a fixing member 11. The output shaft of the electric push rod 12 is fixedly connected to the sliding rack 13. The sliding rack 13 is respectively connected to the two bearing plates 18 through two pairs of distributed support rod assemblies 14. The purpose is to, through the action of the electric push rod 12 and the combined action of the sliding rack 13, realize the closing and opening actions of the two support rod assemblies 14, and then the two bearing plates 18 are joined to carry the switchgear, or the two bearing plates 18 slide away from each other so that the switchgear falls according to the calibrated position.

[0034] Before calibration, the two support rod assemblies 14 are closed, and the two bearing plates 18 are joined. The switchgear to be installed is placed on the two bearing plates 18. After calibration, the second pin 35 jacks up and disengages from the pin hole 241. The electric push rod 12 is started, and the sliding rack 13 moves downward, driving the two bearing plates 18 and the switchgear to be installed thereon to move downward. The purpose is to lower the center of gravity of the switchgear to be installed so that it can fall smoothly from the bearing plate 18.

[0035] As the sliding frame 13 moves downward, the two support rod assemblies 14 move backwards, that is, the two support rod assemblies 14 are spread apart, driving the two bearing plates 18 to slide backwards and apart, and the distribution cabinet falls. In order to further ensure the stability of the fall of the distribution cabinet, the bearing plates 18 are provided with inclined surfaces, so that as the support rod assemblies 14 are spread apart, the two bearing plates 18 are separated to make the distribution cabinet fall at a low position along the inclined surface.

[0036] refer to Figure 5 The bearing plate 18 is also provided with a ball 181 and a roller 182 to facilitate the bearing plate 18 to slide relative to the distribution cabinet.

[0037] The transport frame 1 is provided with two symmetrically distributed guide plates 17 via a rotating shaft 171, i.e., the rotating shaft 171 is rotatably connected to the transport frame 1, and the guide plates 17 are fixedly connected 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 bearing plates 18, so that the two guide plates 17 connect the bearing plates 18 to the ground, so as to facilitate moving the power distribution cabinet onto the bearing plates 18, and the power distribution cabinet to be installed moves onto the bearing plates 18 along the guide plates 17. 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, so as to reduce the friction between the guide plates 17 and the power distribution cabinet to be installed.

[0038] refer to Figure 2 The guide plates 17 are all fixedly connected with straight rods 172, and the straight rods 172 are all provided with first latches 19. The carrier plate 18 is provided with a positioning hole 183, and the positioning hole 183 is engaged with the first latch 19, so as to achieve the positioning and stabilization effect of the guide plate 17 through the engagement of the positioning hole 183 with the first latch 19. The rotating shaft 171 is fixedly connected with a gear 16, and the sliding frame 13 is provided with a rack 15, and the rack 15 is meshed with the gear 16. The sliding frame 13 is also provided with a protrusion 131, and the protrusion 131 is press-fitted with the side of the guide plate 17, so as to limit the flipping 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 guide plate 17 and the straight rod 172 rotate synchronously until the side of the guide plate 17 abuts against the protrusion 131 and remains stationary, the first latch 19 is engaged with the locking hole 183, and then the guide plate 17, the straight rod 172 and the supporting plate 18 form a stable semi-enclosed triangular structure.

[0040] When the power distribution cabinet to be installed falls in the calibration position, the stable semi-enclosed triangle structure formed by the guide plate 17, the straight rod 172 and the bearing plate 18, and the trigger member 3 and the limit rod 23 protect the power distribution cabinet to be installed to prevent it from tipping over during the falling process.

[0041] Specifically, before the calibration operation, to facilitate the smooth movement of the distribution cabinet to be installed onto the bearing plate 18, the limiting rod 23 should avoid interference. During the calibration operation, the limiting rod 23 should maintain a clamping state on the distribution cabinet to be installed. Based on this, the following settings are made: There are two symmetrically distributed extrusion frames 22 on the transport rack 1. The extrusion frames 22 are distributed on both sides of the transport rack 1 and are provided with wedge-shaped blocks thereon. The avoidance effect is achieved through the extrusion cooperation between the limiting rod 23 and the wedge-shaped blocks of the extrusion frames 22.

[0042] Move the two sliders 21 away from each other, and the two limiting rods 23 are controlled to move. The sunk grooves on the guiding frame 25 cooperate with the flanges 33 on the limiting rods 23, and the guiding frame 25 is controlled to move. The telescopic end of the telescopic member 26 extends until the limiting rod 23 presses against the wedge-shaped blocks of the extrusion frame 22. The limiting rod 23 moves upward along the wedge-shaped blocks of the extrusion frame 22, and the cooperation between the flange 33 on the limiting rod 23 and the sunk groove on the guiding frame 25 is cancelled. Then, the limiting rod 23 smoothly moves upward, canceling the blockage of the distribution cabinet to be installed, achieving the avoidance effect. The distribution cabinet to be installed can smoothly move onto the bearing plate 18 through the guiding plate 17. Subsequently, move the two sliders 21 towards each other, and the two limiting rods 23 are controlled to move. The sunk grooves on the guiding frame 25 and the flanges 33 on the limiting rods 23 cooperate again, and the guiding frame 25 and the limiting rod 23 form a stable structure, and the above-mentioned calibration operation can be performed.

[0043] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
