Description

Technical Field

[0001] The utility model relates to the field of low-voltage switch cabinets, and more specifically, to a fixing mechanism for a low-voltage switch cabinet. Background Technique

[0002] A switch cabinet is an electrical device. The external wires of the switch cabinet first enter the main control switch inside the cabinet, and then enter the sub-control switch. Each branch is set as required, such as meters, automatic controls, motor magnetic switches, various AC contactors, etc. Some also have high-voltage and low-voltage switch cabinets, with high-voltage busbars, such as in power plants, etc. Some also have low-frequency load shedding to protect the main equipment. Low-voltage switch cabinets are applicable to industries such as power plants, petroleum, chemical industry, metallurgy, textile, and high-rise buildings, and are used for power transmission, power distribution, and power conversion.

[0003] After the low-voltage switch cabinet is used for a long time, its normal use will be affected due to equipment aging. Therefore, it is necessary to replace the switch cabinet as a whole. However, some existing low-voltage switch cabinets are fixedly connected to the concrete base, and the concrete base may need to be damaged during the replacement process of the switch cabinet, which is not convenient for the subsequent installation of the switch cabinet. Therefore, in order to solve the above problems, we propose a fixing mechanism for a low-voltage switch cabinet. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides a fixing mechanism for a low-voltage switch cabinet, and adopts the following technical solutions:

[0005] A fixing mechanism for a low-voltage switch cabinet includes a base and a frame arranged above the base. Installation blocks are fixedly installed on both sides of the base, and support blocks are fixedly installed on both sides of the frame. Two symmetrically distributed embedded bolts are arranged in each of the two installation blocks. A support plate is fixedly installed inside the frame, and a limit frame is fixedly installed at the top of the frame. A double-axis cylinder is fixedly installed at the top of the support plate. Limit pads are fixedly installed on the inner walls of both sides of the limit frame. A clamping assembly is provided on the double-axis cylinder and the limit frame.

[0006] By adopting the above technical solution, when the device is in use, the staff sets the base at a suitable installation location. Subsequently, the staff sleeves the frame on the side wall of the base, so that the supporting blocks installed on the side wall of the frame are in contact with the tops of the same group of mounting blocks, and the embedded bolts arranged at the tops of the mounting blocks pass through the mounting holes opened at the tops of the supporting blocks and are screwed with the existing mounting nuts, which can play a role in fixing the frame. After the frame is fixed, the staff places the switch cabinet in the limiting frame. There is a limiting pad in the limiting frame, which can play the role of the switch cabinet and achieve the effect of limiting and positioning the switch cabinet, which is beneficial to maintaining the stability of the switch cabinet installation. Subsequently, the clamping assembly is driven to operate by the double-axis cylinder, which can play a role in clamping and fixing the switch cabinet. When the switch cabinet needs to be replaced, the clamping assembly is driven to move in the reverse direction by the double-axis cylinder, so that the clamping assembly is separated from the switch cabinet. Subsequently, the switch cabinet can be taken out, and the effect of disassembling the switch cabinet can be achieved without damaging the base, reducing the waste of materials and facilitating subsequent reinstallation.

[0007] Further, first support blocks are fixedly installed at the ends of the two output shafts of the double-axis cylinder. Second support blocks are fixedly installed at the tops of the two first support blocks. The tops of the two second support blocks slidably penetrate through the frame. Pillars are fixedly installed on the opposite sides of the two second support blocks. Moving grooves are formed on the opposite sides of the two pillars. Support rods are slidably installed in the two moving grooves. Spring are fixedly connected between the opposite sides of the two support rods and the inner walls of the moving grooves on the same side of the same group. Clamping plates are fixedly installed at the opposite ends of the two support rods.

[0008] By adopting the above technical solution, after the switch cabinet is placed inside the limiting frame, the double-axis cylinder is used to drive the first support block of the same group to move. The first support block drives the second support block of the same group to move. The second support block drives the pillars, support rods and clamping plates of the same group to move synchronously, so that the clamping plate contacts the opposite side of the switch cabinet, which can play a role in clamping and fixing the switch cabinet and is beneficial to maintaining the stability of the switch cabinet placement. When the clamping plate contacts the opposite side of the switch cabinet, the clamping plate pushes the support rod of the same group to slide in the moving groove of the same group under the driving force of the double-axis cylinder, and the support rod pushes the spring of the same group to contract. The spring gives a rebound force to the support rod of the same group, which can play a buffering role and is beneficial to reducing the deformation and damage of the switch cabinet due to excessive extrusion force.

[0009] Further, two symmetrically distributed limiting blocks are fixedly installed on the side walls of the opposite ends of the two support rods. Limiting grooves matching the limiting blocks of the same group are formed on the inner walls of the two moving grooves.

[0010] By adopting the above technical solution, when the support rod slides in the moving groove of the same group, the support rod drives the limiting block to slide in the limiting groove on the same side. Through the cooperation of the limiting block and the limiting groove, it is beneficial to maintain the stability of the support rod sliding and help to prevent the support rod from disengaging from the moving groove of the same group.

[0011] Further, stabilizing plates are fixedly installed on both sides of the upper sections of the two clamping plates. Through holes are formed on the surfaces of the stabilizing plates, fixing bolts are arranged in the through holes, fixing nuts are sleeved on the side walls of the fixing bolts, and anti-slip pads are fixedly installed on the inner sides of the same group of clamping plates and stabilizing plates.

[0012] By adopting the above technical solution, after the two clamping plates complete the clamping of the switch cabinet, the staff passes the fixing bolts through the holes formed in the side wall of the switch cabinet and makes the fixing bolts pass through the through holes formed in the surface of the stabilizing plate, and then screwing the fixing nut with the fixing bolt can play a role in fixing the stabilizing plate, and further play a role in further fixing the switch cabinet, which is beneficial to maintaining the stability of the placement of the switch cabinet.

[0013] Further, mounting plates are fixedly installed on both sides of the lower section of the limiting frame, and two symmetrically distributed stabilizing rods are fixedly installed between the two mounting plates. Both ends of the two stabilizing rods slidably penetrate through the same group of first support blocks.

[0014] By adopting the above technical solution, when the double-shaft cylinder drives the first support block to move, the two first support blocks slide on the two stabilizing rods. Through the cooperation of the two stabilizing rods, the first support block is stabilized, which is beneficial to maintaining the stability of the movement of the two first support blocks.

[0015] Further, four symmetrically distributed positioning columns are fixedly installed on the top ends of the bases, and positioning holes matching the positioning columns are formed on the surface of the support plate.

[0016] By adopting the above technical solution, through the arrangement of the positioning columns at the top end of the base, when the frame is placed on the upper section of the base, the positioning columns are engaged with the positioning holes formed at the top end of the support plate, which plays a role in positioning and stabilizing the frame and is beneficial to maintaining the accuracy of the installation of the frame.

[0017] Further, two symmetrically distributed sliders are fixedly installed on the inner walls of both sides of the frame, and sliding grooves matching the same group of sliders are formed on both sides of the base.

[0018] By adopting the above technical solution, when the frame slides on the side wall of the base, the frame drives the sliders to slide in the sliding grooves formed on the side wall of the base. Through the cooperation of the sliders and the sliding grooves, the frame is positioned and stabilized.

[0019] In summary, the utility model includes the following beneficial technical effects:

[0020] (1) In the present utility model, through the setting of the clamping assembly, it plays a role in clamping and fixing the switch cabinet, facilitating subsequent disassembly by the staff. Moreover, through the cooperation of the embedded bolts and the support blocks, the frame can be fixed, and thus the switch cabinet can be fixed. When the switch cabinet needs to be replaced, only the switch cabinet needs to be removed, without damaging the base, which is convenient for subsequent reinstallation and helps reduce material waste.

[0021] (2) In the present utility model, through the cooperation of the stabilizing plate, the fixing bolt and the fixing nut, after the side of the clamping plate in contact with the switch cabinet, the staff passes the fixing bolt through the switch cabinet and penetrates the stabilizing plate of the same group, and then through the screwing of the fixing bolt and the fixing nut, it can play a role in assisting in fixing the switch cabinet, which is beneficial to improving the installation stability of the switch cabinet.

[0031] The following further elaborates on the present utility model in conjunction with the attached Figures 1-4 drawings.

[0032] Please refer to Figures 1-4 , a fixing mechanism for a low-voltage switchgear, comprising a base 1 and a frame 5 arranged above the base 1. Installation blocks 2 are fixedly installed on both sides of the base 1, support blocks 4 are fixedly installed on both sides of the frame 5, two symmetrically distributed embedded bolts 3 are provided in each of the two installation blocks 2, a support plate 14 is fixedly installed inside the frame 5, a limit frame 8 is fixedly installed at the top of the frame 5, a double-shaft cylinder 16 is fixedly installed at the top of the support plate 14, limit pads are fixedly installed on the inner walls of both sides of the limit frame 8, four symmetrically distributed positioning columns 15 are fixedly installed at the top of the base 1, positioning holes matching the positioning columns 15 are formed on the surface of the support plate 14, two symmetrically distributed sliders 17 are fixedly installed on the inner walls of both sides of the frame 5, and sliding grooves matching the sliders 17 in the same group are formed on both sides of the base 1.

[0033] When the device is in use, the staff member sets the base 1 at a suitable installation location. Subsequently, the staff member slips the frame 5 over the side wall of the base 1, making the supporting blocks 4 installed on the side wall of the frame 5 fit against the tops of the same-group mounting blocks 2, and causing the embedded bolts 3 provided at the tops of the mounting blocks 2 to pass through the mounting holes opened at the tops of the supporting blocks 4. By screwing with existing mounting nuts, the frame 5 can be fixed. Due to the provision of the positioning posts 15 at the top of the base 1, when the frame 5 is placed on the upper section of the base 1, the positioning posts 15 are engaged with the positioning holes opened at the tops of the support plates 14, playing a role in positioning and stabilizing the frame 5, which is conducive to maintaining the accuracy of the installation of the frame 5. When the frame 5 slides on the side wall of the base 1, the frame 5 drives the slider 17 to slide within the chute opened on the side wall of the base 1. Through the cooperation of the slider 17 and the chute, the frame 5 is positioned and stabilized.

[0034] The double-axis cylinder 16 and the limit frame 8 are provided with clamping components. At the ends of the output shafts of both sections of the double-axis cylinder 16, first support blocks 6 are fixedly installed. On the tops of the two first support blocks 6, second support blocks 9 are fixedly installed. The two second support blocks 9 slide through the frame 5 at the top. On the opposite sides of the two second support blocks 9, columns 10 are fixedly installed. On the opposite sides of the two columns 10, movable grooves 18 are opened. In the two movable grooves 18, support rods 11 are slidably installed. Between the opposite sides of the two support rods 11 and the inner walls of the opposite sides of the same-group movable grooves 18, springs 19 are fixedly connected. At the opposite ends of the two support rods 11, clamping plates 12 are fixedly installed.

[0035] After the frame 5 is installed, the staff member places the switch cabinet in the limit frame 8. The limit frame 8 is provided with a limit pad, which can play the role of the switch cabinet and achieve the effect of limiting and positioning the switch cabinet, being conducive to maintaining the stability of the installation of the switch cabinet. After the switch cabinet is placed inside the limit frame 8, the double-axis cylinder 16 is driven to move the first support blocks 6 of the same group. The first support blocks 6 drive the second support blocks 9 of the same group to move. The second support blocks 9 drive the columns 10, support rods 11, and clamping plates 12 of the same group to move synchronously, making the side of the clamping plate 12 opposite to the switch cabinet come into contact, which can play the role of clamping and fixing the switch cabinet, being conducive to maintaining the stability of the placement of the switch cabinet. When the side of the clamping plate 12 opposite to the switch cabinet comes into contact, the clamping plate 12 drives the support rod 11 of the same group to slide within the movable groove 18 of the same group under the driving force of the double-axis cylinder 16, and the support rod 11 pushes the spring 19 of the same group to contract. The spring 19 gives a rebounding force to the support rod 11 of the same group, which can play a buffering role and is conducive to reducing the deformation and damage of the switch cabinet due to excessive extrusion force.

[0036] At opposite ends of the two support rods 11, two symmetrically distributed limit blocks are fixedly installed on the side walls. Limit grooves matching the limit blocks of the same group are formed on the inner walls of the two movable grooves 18. When the support rod 11 slides within the movable groove 18 of the same group, the support rod 11 drives the limit block to slide within the limit groove on the same side. Through the cooperation of the limit block and the limit groove, it is beneficial to maintain the stability of the sliding of the support rod 11 and helps to prevent the support rod 11 from disengaging from the movable groove 18 of the same group.

[0037] On both sides of the upper section of the two clamping plates 12, stabilizing plates 13 are fixedly installed. Through holes are formed on the surfaces of the stabilizing plates 13. Fixing bolts are provided within the through holes. Fixing nuts are sleeved on the side walls of the fixing bolts. Anti-slip pads are fixedly installed on the inner sides of the clamping plates 12 and the stabilizing plates 13 of the same group. After the two clamping plates 12 complete the clamping of the switch cabinet, the staff passes the fixing bolts through the holes formed on the side wall of the switch cabinet and makes the fixing bolts pass through the through holes formed on the surface of the stabilizing plate 13. Subsequently, by screwing the fixing nut with the fixing bolt, the stabilizing plate 13 can be fixed, and further, the switch cabinet can be fixed, which is beneficial to maintaining the stability of the placement of the switch cabinet.

[0038] On both sides of the lower section of the limit frame 8, mounting plates 7 are fixedly installed. Between the two mounting plates 7, two symmetrically distributed stabilizing rods are fixedly installed. Both ends of the two stabilizing rods slide through the first support blocks 6 of the same group. When the double-axis cylinder 16 drives the first support blocks 6 to move, the two first support blocks 6 slide on the two stabilizing rods. Through the cooperation of the two stabilizing rods, the first support blocks 6 are stabilized, which is beneficial to maintaining the stability of the movement of the two first support blocks 6.

[0039] The implementation principle of the embodiment of the present utility model is as follows: When the device is in use, the staff sets the base 1 at a suitable installation location. Subsequently, the staff sleeves the frame 5 on the side wall of the base 1, makes the support blocks 4 installed on the side wall of the frame 5 fit with the tops of the mounting blocks 2 of the same group, and makes the embedded bolts 3 provided at the tops of the mounting blocks 2 pass through the mounting holes formed on the tops of the support blocks 4. By screwing with the existing mounting nuts, the frame 5 can be fixed. After the frame 5 is fixed, the staff places the switch cabinet within the limit frame 8. A limit pad is provided within the limit frame 8, which can play the role of the switch cabinet and achieve the effect of limiting and positioning the switch cabinet, which is beneficial to maintaining the stability of the installation of the switch cabinet. Subsequently, by driving the clamping assembly to operate through the double-axis cylinder 16, the role of clamping and fixing the switch cabinet can be achieved. When the switch cabinet needs to be replaced, by driving the clamping assembly to move in the reverse direction through the double-axis cylinder 16, the clamping assembly can be disengaged from the switch cabinet. Subsequently, the switch cabinet can be taken out, and the effect of disassembling the switch cabinet can be achieved, without damaging the base 1, reducing the waste of materials, and being convenient for subsequent reinstallation.

[0040] The above are all preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present utility model shall be covered within the protection scope of the present utility model.
