Description

Technical Field

[0001] The invention relates to the technical field of power distribution cabinet assembly, in particular to an electric power distribution cabinet assembly platform. Background Art

[0002] An electric power distribution cabinet is a closed, metal device that is usually placed in a power room within a building or industrial facility. Various electrical devices such as circuit breakers, switches, contactors, fuses, transformers, etc. are installed on the rails inside. These components work together to achieve the distribution and control of electrical energy.

[0003] Existing power distribution cabinets are all fixed with side panels, and each side panel is evenly spaced with multiple straight slots to facilitate the installation of guide rails. Workers need to install the guide rails on the side panels first, and then install various electrical equipment on the guide rails. During the installation of the guide rails, workers need to hold the guide rails and fit them to the side panels (such as Fig.10 As shown), and the distance between the two guide rails needs to be adjusted according to the model of the electrical equipment. After the distance between the two guide rails is adjusted and the two guide rails are aligned with the straight grooves of the side panels, the staff installs the two guide rails in the distribution cabinet by connecting and fixing them with bolts.

[0004] When workers install guide rails in power distribution cabinets, the following problems and defects exist: 1. At present, when workers hold the guide rails and fit them to the side panels, it is difficult to ensure that the length direction of the guide rails is perpendicular to the length direction of the side panels by manually placing the guide rails. It is easy for the two guide rails to tilt with the side panels, causing the electrical equipment installed on the guide rails to also tilt with the side panels, thereby affecting the subsequent installation process of the electrical equipment and causing the center of gravity of the electrical equipment to shift, reducing the stability of the equipment; 2. When workers install two guide rails, it is difficult to ensure that the two guide rails are parallel, and some electrical equipment needs to use two parallel guide rails as the installation base during installation. Therefore, the above problems can easily make it difficult to install some electrical equipment on two non-parallel guide rails, so that workers need to correct and debug the position of the guide rails to ensure that the two guide rails are parallel and adjust the spacing. This not only increases the alignment time and reduces the installation efficiency, but also increases the difficulty of installation. Summary of the invention

DETAILED DESCRIPTION

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0033] like Figure 1 and Figure 2 As shown, an assembly platform for a power distribution cabinet includes a base 1, an upper end surface of the base 1 is fixedly provided with a mounting seat, a push rod 2 with an axis extending from front to rear slidingly penetrates the mounting seat, the push rod 2 is driven to move left and right by an external cylinder (not shown in the figure), a rear end surface of the push rod 2 is fixedly provided with a circular plate 3 in a circular shape, two horizontal plates 31 are slidably provided on the circular plate 3 and penetrated, a U-shaped frame 32 with an opening facing upward is fixedly provided on the rear end surfaces of the two horizontal plates 31, two connecting springs 33 sleeved on the horizontal plates 31 are jointly provided between the U-shaped frame 32 and the annular plate 3, a first guide plate 5 with a cavity inside is fixedly provided on the rear end surface of the U-shaped frame 32, the left and right ends of the first guide plate 5 are both open, and a guiding mechanism 4 is provided on the first guide plate 5.

[0034] like Figure 2 and Figure 3As shown, the guiding mechanism 4 includes a fixed shaft 41 whose axis extends from front to back, two fixed shafts 41 opposite to each other are fixedly arranged in the cavity of the first guide plate 5, a clamping unit 45 is arranged between the two fixed shafts 41, a first rotating plate 42 is rotatably sleeved on each fixed shaft 41, and a positioning assembly 421 is arranged on the two first rotating plates 42, two second rotating plates 43 rotatably sleeved on the fixed shaft 41 are rotatably arranged on the first guide plate 5, and the two second rotating plates 43 are both located at the rear side of the corresponding first rotating plates 42, sliding grooves are opened on the first rotating plate 42 and the second rotating plate 43, and a fixed rod 44 with an axis extending from front to back is slidably arranged in the sliding groove along its length direction through a sliding block.

[0035] like Figure 2 , Figure 6 and Figure 7 As shown, two left-right opposite vertical plates 6 are fixedly provided on the lower end surface of the horizontal section of the U-shaped frame 32, a centering component 722 is provided on the vertical plate 6, an adjustment mechanism 7 is provided between the two vertical plates 6, a second guide plate 8 is provided below the first guide plate 5, a clamping unit 45 is also provided on the second guide plate 8, base plates 71 are hinged on the left and right sides of the second guide plate 8, and an adjustment unit 72 is provided on each base plate 71.

[0036] During work, the staff places the distribution cabinet 9 horizontally on the base 1 and makes the opening of the distribution cabinet 9 parallel to the rear end surface of the mounting seat. Then, the two guide rails 92 are clamped and fixed on the first guide plate 5 and the second guide plate 8 respectively through the clamping unit 45. Then, the staff adjusts the distance between the first guide plate 5 and the second guide plate 8 through the adjustment mechanism 7, that is, adjusts the distance between the two guide rails 92, so that the staff can install different sizes and types of electrical equipment, thereby enhancing the flexibility and adaptability of the device.

[0037] Then the external cylinder works to drive the push rod 2 close to the distribution cabinet 9, and the push rod 2 drives the annular plate 3 to move synchronously, and the annular plate 3 drives the cross plate 31 and the connecting spring 33 to move synchronously, and the two cross plates 31 drive the U-shaped frame 32 and the first guide plate 5 to move. At this time, the annular plate 3 gradually compresses the connecting spring 33 and makes the cross plate 31 slide on the annular plate 3 until the first guide plate 5 inserts the fixing rod 44 into the straight groove of the side plate 91 through the positioning assembly 421, and clamps the first guide plate 5 on the side plate 91 through the clamping unit 45, so that the guide rail 92 on the first guide plate 5 is vertically fitted with the side plate 91.

[0038] During this process, the second guide plate 8 gradually approaches the side plate 91, and through the cooperation of the clamping unit 45 and the adjustment unit 72, the guide rail 92 on the second guide plate 8 is also vertically fitted with the side plate 91. The staff installs the two guide rails 92 horizontally on the side plate 91. The two horizontally distributed guide rails 92 provide a stable support for the electrical equipment, preventing the electrical equipment from shaking during operation, thereby improving the stability and safety of the equipment.

[0039] like Figure 2 , Figure 3 and Figure 5 As shown, the clamping unit 45 includes a fixed cylinder 451, the annular plate 3 is fixedly provided with the fixed cylinder 451, the fixed cylinder 451 is rotatably provided with a spiral rod 452 whose axis extends from front to back, and the spiral rod 452 rotates and penetrates the first guide plate 5, the inner wall of the fixed cylinder 451 is fixedly provided with two upper and lower opposite protrusions 453, and the spiral section of the spiral rod 452 cooperates with the protrusion 453, the rear end surface of the spiral rod 452 is fixedly provided with a driving gear 454, and two left and right opposite card plates are slidably provided in the cavity of the first guide plate 5 457, a connecting strip 456 is provided on one side of the two locking plates 457 away from the driving gear 454, and a locking spring 458 is provided between the two locking plates 457 and the corresponding connecting strip 456. Two rack plates 455 meshing with the driving gear 454 are provided in the cavity of the first guide plate 5 through the left and right sliding of the transverse plate. The two rack plates 455 are symmetrical about the axis of the fixed cylinder 451, and the two rack plates 455 are fixedly connected to the corresponding connecting strip 456. A clamping assembly 459 is provided on the two locking plates 457.

[0040] like Figure 3 and Figure 4 As shown, the clamping assembly 459 includes a fixed plate 4591, and each of the positioning plates 457 is fixedly provided with two upper and lower opposite fixed plates 4591, and each of the fixed plates 4591 is slidably provided with two symmetrical and L-shaped clamping plates 4592, and both sides of the vertical section of each clamping plate 4592 are chamfered, and a clamping spring 4593 is commonly provided between the horizontal section of each clamping plate 4592 and the corresponding positioning plate 457.

[0041] During operation, the staff pushes the guide rail 92 to contact the vertical section of the clamping plate 4592, and causes the clamping plate 4592 to gradually compress the clamping spring 4593, and then fixes the two guide rails 92 to the first guide plate 5 and the second guide plate 8 respectively through the compressed clamping spring 4593. Then, when the annular plate 3 drives the first guide plate 5 and the second guide plate 8 to approach the side plate 91, the first guide plate 5 first contacts the side plate 91, and the annular plate 3 continues to move toward the side plate 91, so that the annular plate 3 drives the fixing cylinder 451 and the protrusion 453 to move simultaneously. The fixing cylinder 451 and the protrusion 453 drive the screw rod 452 to rotate, the screw rod 452 drives the driving gear 454 to rotate synchronously, the driving gear 454 drives the two rack plates 455 to rotate, the two rack plates 455 drive the corresponding connecting strips 456 to move, the connecting strips 456 drive the positioning springs 458 and the positioning plates 457 to move synchronously, so that the two positioning plates 457 drive the corresponding clamping plates 4592 to move away from each other, ensuring that the left and right sides of the guide rail 92 are evenly stressed during installation, thereby improving the stability of the guide rail 92 during installation.

[0042] During this process, the two locking plates 457 are in contact with the corresponding first rotating plate 42 and second rotating plate 43, so that the first rotating plate 42 and the second rotating plate 43 rotate around the fixed axis 41, and the first rotating plate 42 and the second rotating plate 43 drive the corresponding fixed rod 44 to slide on the inner wall of the straight groove of the side plate 91 until the first rotating plate 42 and the second rotating plate 43 no longer rotate and are fixed by the locking plates 457. At this time, the guide rail 92 is in contact with the side plate 91, and the length direction of the guide rail 92 is perpendicular to the length direction of the side plate 91, ensuring that the position of the guide rail 92 in the distribution cabinet 9 is stable, and preventing the guide rail 92 from tilting with the side plate 91 due to the offset of the center of gravity of the guide rail 92.

[0043] During the contact between the second guide plate 8 and the side plate 91, the connecting strip 456 on the first guide plate 5 gradually compresses the locking spring 458, and then the clamping unit 45 on the second guide plate 8 drives the clamped guide rail 92 to fit and fix with the side plate 91, so that the two guide rails 92 are vertically fitted with the side plate 91, which facilitates the fixed installation of the two guide rails 92 on the side plate 91. Secondly, it avoids the problem of electrical equipment being unable to be installed due to the inclination between the two guide rails 92, thereby improving the installation accuracy.

[0044] like Figure 3 and Figure 6As shown, the positioning assembly 421 includes two left-right symmetrical guide plates 4212, a rectangular plate 4211 is fixedly provided on the two first rotating plates 42, an L-shaped guide plate 4212 is fixedly sleeved on the two first rotating plates 42, and a guide spring 4213 is commonly provided between the vertical section of each guide plate 4212 and the rectangular plate 4211. Taking the left guide plate 4212 as an example, the front side surface of the vertical section of the left guide plate 4212 is inclined backward from left to right.

[0045] During operation, when the first guide plate 5 approaches the side plate 91, the vertical section of the guide plate 4212 contacts the side plate 91, so that the guide plate 4212 gradually compresses the guide spring 4213. After the inclined surface of the guide plate 4212 is no longer in contact with the side plate 91, the compressed guide spring 4213 of the guide plate 4212 is reset and pressed against one side of the side plate 91. Since the distance from the fixing rod 44 to the vertical section of the guide plate 4212 is equal to the distance from one side of the side plate 91 to the straight slot, and the guide plate 4212 and the fixing rod 44 move synchronously with the first guide plate 5, the guide plate 4212 drives the fixing rod 44 to be accurately inserted into the straight slot of the side plate 91, which simplifies the operation process, saves the time of the staff in aligning the fixing rod 44 and the straight slot, and improves the work efficiency and installation accuracy.

[0046] like Figure 6 , Figure 7 and Figure 8 As shown, the adjusting mechanism 7 includes a positioning plate 721 with a hollow interior, and the lower end surfaces of the two vertical plates 6 are jointly fixed with a positioning plate 721, and the left and right ends of the positioning plate 721 are both open. A rotating roller 73 with an axis extending from top to bottom is rotatably provided on the positioning plate 721, and the rotating roller 73 is connected to an external motor (not shown in the figure). Two left and right opposite screw rods 74 are rotatably provided at the bottom of the inner cavity of the positioning plate 721, and the screw rods 74 pass through the upper end surface of the positioning plate 721, and a belt 75 is commonly provided between the two screw rods 74 and the rotating roller 73. A movable plate 76 is slidably sleeved up and down on each screw rod 74, and a movable plate 76 is slidably provided on each vertical plate 6, and the two movable plates 76 are threadedly matched with the corresponding screw rods 74, and the second guide plate 8 is slidably provided on the lower end surfaces of the two movable plates 76.

[0047] like Figure 5 , Figure 6 and Figure 7As shown, a horizontal plate 77 is provided on the inner wall of the annular plate 3 for sliding up and down, and a fixed cylinder 451 is also fixed on the horizontal plate 77. Two sliding plates 78 opposite to each other are fixed on the front end face of the second guide plate 8, and each sliding plate 78 is slidably arranged on the positioning plate 721 forward and backward. The centering component 722 includes a centering plate 7221. Two left-right symmetrical centering plates 7221 are slidably arranged in the inner cavity of the positioning plate 721, and a mounting plate 7223 is fixedly provided on the front end face of each centering plate 7221. The left centering plate 7221 is taken as an example for explanation. The left end face of the left centering plate 7221 is inclined backward from left to right, and a centering spring 7222 is commonly arranged between each centering plate 7221 and the horizontal plate 77.

[0048] During operation, after the staff has pre-fixed the guide rail 92 on the first guide plate 5 and the second guide plate 8, the staff drives the rotating roller 73 to rotate through an external motor, so that the rotating roller 73 drives the two screw rods 74 to rotate synchronously through the belt 75, so that the two movable plates 76 move upward or downward synchronously with the rotation of the corresponding screw rods 74, and the two movable plates 76 drive the second guide plate 8 and the guide rail 92 to move synchronously, and the second guide plate 8 drives the two sliding plates 78 to move synchronously, so that the two sliding plates 78 drive the horizontal plate 77 and the fixed cylinder 451 to move synchronously. After the distance between the first guide plate 5 and the second guide plate 8 meets the preset requirements, the external motor stops working, so that the staff can adjust the distance between the two guide rails 92 according to the models and sizes of different electrical equipment, thereby enhancing the flexibility and adaptability of the device, and by adjusting the spacing of the guide rails 92, the distribution of electrical equipment in the distribution cabinet 9 is made more compact, thereby improving the space utilization rate of the distribution cabinet 9.

[0049] Subsequently, the annular plate 3 and the positioning plate 721 are pushed by the pushing rod 2 to approach the side plate 91, and the inclined surfaces of the two centering plates 7221 contact the two sides of the door frame of the distribution cabinet 9, so that the two centering plates 7221 are close to each other and squeeze the corresponding centering springs 7222, ensuring that the positioning plate 721 and the annular plate 3 are aligned with the center of the distribution cabinet 9, so that the first guide plate 5 and the second guide plate 8 drive the corresponding guide rails 91 to smoothly enter the distribution cabinet 9, which helps to guide the fixing rod 44 to insert into the straight groove of the side plate 91 and assist the guide rails 92 to be installed in the distribution cabinet 9, which helps to improve the installation accuracy and quality, and the mounting plate 7223 moves synchronously with the centering plate 7221, so that the guide rails 92 on the second guide plate 8 are aligned with the center of the second guide plate 8, which is convenient for the subsequent guiding installation of the guide rails 92.

[0050] like Figure 6 , Figure 7 and Figure 8As shown, each base plate 71 is provided with a positioning groove 723, and the adjustment unit 72 includes an adjustment plate 724. An adjustment plate 724 is slidably arranged in each positioning groove 723. An adjustment spring 727 is commonly arranged between the two positioning plates 721 and the second guide plate 8. A direction plate 725 is fixedly arranged on the rear end face of each adjustment plate 724, and a limiting cylinder 726 is fixedly arranged on the front end faces of the two direction plates 725. The limiting cylinder 726 is composed of a conical section and a cylindrical section from front to back.

[0051] like Figure 5 and Figure 7 As shown, two left-right symmetrical auxiliary plates 321 are arranged on the vertical section of the U-shaped frame 32 to slide left and right and penetrate through the auxiliary plates 321. The auxiliary plates 321 are L-shaped, and an auxiliary spring 322 is arranged between each vertical section of the auxiliary plate 321 and the corresponding vertical section of the U-shaped frame 32. Taking the left auxiliary plate 321 as an example, the left end surface of the left auxiliary plate 321 is inclined backward from left to right, and a toggle plate 323 is fixedly arranged on the horizontal sections of the two auxiliary plates 321.

[0052] During operation, in the process that the annular plate 3 and the positioning plate 721 are pushed close to the side plate 91 by the pushing rod 2, the inclined surfaces of the two auxiliary plates 321 contact the inner walls on both sides of the distribution cabinet 9, so that the two auxiliary plates 321 approach each other and gradually squeeze the corresponding auxiliary springs 322, and the auxiliary plates 321 assist the annular plate 3 to be aligned with the left and right centers of the distribution cabinet 9, thereby further improving the installation accuracy of the guide rail 92, and the two toggle plates 323 move synchronously with the corresponding auxiliary plates 321, so that the guide rail 92 and the first guide plate 5 and the second guide plate 8 on which they are placed are centered, so that the distances from the left and right sides of the installed guide rail 9 to the inner walls of the distribution cabinet 9 are consistent, ensuring that the guide rail 92 can enter the distribution cabinet 9 and fit with the side plates 91, thereby avoiding the problem that the guide rail 92 cannot be installed in the distribution cabinet 9 due to one side of the guide rail 9 being blocked by the distribution cabinet 9.

[0053] After the guide rail 92 on the first guide plate 5 is vertically fitted with the side plate 91, the push rod 2 and the annular plate 3 push the second guide plate 8 close to the side plate 91 through the sliding plate 78. At this time, the two limiting cylinders 726 are in contact with the corresponding fixing rods 44 on the second rotating plate 43, so that the two limiting cylinders 726 drive the corresponding direction plates 725 to move, and the direction plates 725 drive the corresponding adjustment plates 724 to slide on the inner wall of the positioning groove 723, and the adjustment plates 724 gradually stretch the adjustment springs 727 until the two fixing cylinders 451 are inserted into the cylindrical sections of the corresponding limiting cylinders 726, and the position of the second guide plate 8 is adjusted. Fix so that the second guide plate 8 and the guide rail 92 are synchronously centered with the side plate 91, ensuring that the length directions of the two guide rails 92 are perpendicular to the length direction of the side plate 91, avoiding the problem that the electrical equipment cannot be installed due to the inclination between the two guide rails 92. Secondly, in the process of horizontally fixing the first guide plate 5 and the side plate 92, the second guide plate 8 uses the first guide plate 5 as the installation reference and cooperates with the fixing rod 44 and the limiting cylinder 726, so that the limiting cylinder 726 and the first guide plate 5 guide the installation of the guide rail 92 on the second guide plate 8, which helps to reduce errors during the installation process and improve the installation accuracy and system stability.
