Description

Technical Field

[0001] The invention relates to the technical field of switch cabinet brackets, and in particular to a mobile switch cabinet bracket device. Background Art

[0002] Switchgear is an electrical equipment, mainly used in power generation, transmission, distribution and power conversion of power systems. Switchgear can effectively control the equipment in the power system. By operating the switch, it can realize the on-off control of the circuit, thereby meeting the operation requirements of different equipment.

[0003] In order to prevent moisture from the bottom from entering the switch cabinet, a bracket is generally placed at the bottom of the switch cabinet, and some brackets are also equipped with universal wheels at the bottom of the bracket to facilitate the small-range movement of the switch cabinet, so that the switch cabinet can be moved at will.

[0004] At present, most brackets need to have extremely strong load-bearing effects, so general brackets are made of metal materials such as channel steel or I-beam, plus the weight of the switch cabinet, the weight of the bracket and the switch cabinet will be concentrated on the connection between the moving wheel and the bracket, and most of the connections are movable connections. With the increase of usage time, the connection between the moving wheel and the bracket is prone to deformation, resulting in immobility. Severe damage to the moving wheel will also cause the bracket to tilt, causing the switch cabinet to tilt and cause safety accidents. Although some brackets without moving wheels will not have this situation, a large number of workers are required to move the switch cabinet, which takes a lot of time, and manual movement is impossible in some small spaces, resulting in more laborious movement of the switch cabinet. Summary of the invention

[0005] Technical issues to be solved

[0006] The purpose of the present invention is to overcome the deficiencies of the prior art, meet practical needs, and provide a mobile switch cabinet bracket device to solve the above technical problems.

[0007] Technical Solution

[0008] In order to achieve the purpose of the present invention, the technical solution adopted by the present invention is:

[0009] A mobile switch cabinet bracket device comprises a switch cabinet, wherein the bottom of the switch cabinet is fixedly connected to the bracket via a cover plate, and the cover plate is fixedly connected to the switch cabinet, the bottom of the bracket is provided with universal wheels in a rectangular array, the bracket comprises a bottom bracket fixedly connected to the cover plate, and a shaft rod mounting hole for a driving support rod and a placement belt groove for placing a toothed belt are provided on a side of the bracket close to the cover plate, wherein the shaft rod mounting holes are distributed in a rectangular array, and each of the shaft rod mounting holes is communicated with the placement belt groove;

[0010] A steering cavity is also provided on the inner side of the bottom support plate, and the steering cavity is communicated with both ends of the placement belt groove, wherein steering wheels are symmetrically installed in the steering cavity, and the steering wheels are movably connected to the bottom support plate through a pin shaft.

[0011] As a further technical solution of the present invention, a toothed belt is placed in the belt placement groove, and the toothed belt bypasses the outer side of the steering wheel when passing through the steering cavity. A mounting groove is also provided on the side of the bottom support plate, and the mounting groove is connected to the side of the belt placement groove, and the mounting groove is located below the belt placement groove;

[0012] A positioning tooth is provided at the upper end of the side surface of the installation groove, and a first thread is provided below the positioning tooth.

[0013] As a further technical solution of the present invention, a driving support rod is installed in each of the shaft mounting holes, and the driving support rod has a support column movably connected to the shaft mounting hole, and an installation bearing is interference fit at one end of the support column close to the shaft mounting hole, and the outer ring of the installation bearing is interference fit with the shaft mounting hole.

[0015] When the toothed belt moves, the toothed belt and the synchronous pulley are meshed with each other, so that the synchronous pulley drives the support column to rotate. Since the support column is installed in the shaft mounting hole through the mounting bearing, the support column will rotate in the shaft mounting hole, and each synchronous pulley is meshed with the toothed belt, thereby driving multiple support columns to rotate simultaneously through the toothed belt.

[0016] As a further technical solution of the present invention, a lifting support plate is provided under the driving support rod, and the lifting support plate has a center plate located in the middle position and edge plates located on both sides, and the center plate and the edge plates are respectively located under the bottom support plate, and through holes corresponding to the support columns are also opened in the center plate and the edge plates.

[0018] When the toothed belt drives multiple set support columns to rotate simultaneously, the threaded column and the threaded sleeve at the bottom of the support column cooperate with each other, and the threaded cooperation at the connection point pushes the center plate and the edge plate to rise and fall simultaneously. When descending, the lifting bracket and the driving support rod cooperate to lift the bracket until the universal wheel is separated from the ground, and the multiple driving support rods will evenly distribute the load on the bracket, thereby increasing the load-bearing performance of the switch cabinet bracket, and can also prevent damage to the connection between the universal wheel and the bracket.

[0019] As a further technical solution of the present invention, an adjusting turntable is movably connected in the installation groove, and the adjusting turntable has an anti-skid turntable and a driving pulley arranged in an integrated manner, wherein the driving pulley is located above the anti-skid turntable, and the driving pulley is meshed with the toothed belt, and a molded limit block is arranged above the driving pulley, and the limit block is engaged with the toothed belt during the downward movement, and the anti-skid turntable is located below the toothed belt, and one side of the anti-skid turntable extends to the side of the bottom support plate;

[0021] Since the anti-slip turntable and the driving pulley are integrated into one, the worker only needs to rotate the anti-slip turntable, and through the mutual engagement of the driving pulley and the toothed belt, the toothed belt is driven to move on the inner side of the belt groove, thereby driving all the support columns to rotate synchronously. No separate adjustment is required, which saves a lot of time. In addition, there is no need to remove the switch cabinet from above the bottom pallet when rotating the support column, which makes it more convenient for workers to move the switch cabinet.

[0022] As a further technical solution of the present invention, the upper part of the driving pulley is movably connected to the cover plate through a bearing, the toothed belt is located below the cover plate, and the top of the steering wheel is movably connected to the cover plate through a pin shaft.

[0023] As a further technical solution of the present invention, the universal wheel is located between the center plate and the edge plate, and the universal wheel can rotate between the center plate and the edge plate.

[0024] (3) Beneficial effects:

[0025] A. In the present invention, a lifting support plate that can be raised and lowered is provided at the bottom of the bracket, and a driving support rod for transmission is provided between the bracket and the lifting support plate. The lifting and lowering of the lifting support plate is controlled by the driving support rod, and the bearing pressure of the universal wheel is reduced, thereby preventing the bracket and the universal wheel from being damaged due to long-term force.

[0026] B. In the present invention, since each support column is provided with a synchronous pulley at the end thereof, and each synchronous pulley is connected in series through a toothed belt, when the anti-skid turntable drives the driving pulley to rotate, the driving pulley and the toothed belt are meshed with each other, so that the multiple support columns are rotated simultaneously under the meshing of the toothed belt and the synchronous pulley, thereby ensuring the normal lifting of the lifting pallet, and the moving distance of each support column is the same, ensuring the uniform distribution of the load on the bracket, and also facilitating the workers to simultaneously control multiple driving struts;

[0027] C. In the present invention, a corresponding threaded sleeve is provided at the bottom of each support column. When the support column rotates, the center plate and the edge plate are synchronously raised or lowered through the threaded cooperation between the support column and the threaded sleeve. When the switch cabinet is in use, the bracket can be lifted as a whole to prevent gravity from being applied to the connection between the universal wheel and the bracket for a long time, thereby preventing the connection between the bracket and the universal wheel from being deformed and damaged after long-term use, thereby extending the service life;

[0028] D. In the present invention, the operator presses down the anti-skid turntable so that the positioning slot is connected with the positioning tooth at the installation groove position. After reaching the bottom, the operator rotates the fastening base.

[0042] A steering cavity 54 is also provided on the inner side of the bottom support plate 51, and the steering cavity 54 is connected to both ends of the placement groove 53, wherein a steering wheel 55 is symmetrically installed in the steering cavity 54, and the steering wheel 55 is movably connected to the bottom support plate 51 through a pin shaft to ensure the normal rotation of the steering wheel 55 inside the steering cavity 54.

[0043] Furthermore, a toothed belt 8 is placed in the belt placement groove 53, and the toothed belt 8 bypasses the outer side of the steering wheel 55 when passing through the steering cavity 54. A mounting groove 56 is also provided on the side of the bottom support plate 51. The mounting groove 56 is connected to the side of the belt placement groove 53, and the mounting groove 56 is located below the belt placement groove 53. The toothed belt 8 will pass through each shaft mounting hole 52 when the belt placement groove 53 moves.

[0044] To be more specific, a driving support rod 10 is installed in each of the shaft mounting holes 52. The driving support rod 10 has a support column 101 movably connected to the shaft mounting hole 52, and an installation bearing 103 is interference fit at one end of the support column 101 close to the shaft mounting hole 52, and the outer ring of the installation bearing 103 is interference fit with the shaft mounting hole 52, so that the support column 101 can only rotate horizontally on the inner side of the shaft mounting hole 52. Since a cover plate 4 is installed on the top, the support column 101 can be prevented from moving up and down in the shaft mounting hole 52.

[0045] Furthermore, the end of the support column 101 passes through the shaft mounting hole 52 and extends into the placement belt groove 53, and the end of the support column 101 is fixedly connected with a synchronous pulley 104, and each of the synchronous pulleys 104 is engaged with the toothed belt 8 placed in the placement belt groove 53.

[0046] By adopting the above technical solution, when the toothed belt 8 moves, the toothed belt 8 and the synchronous pulley 104 are meshed with each other, so that the synchronous pulley 104 drives the support column 101 to rotate. Since the support column 101 is installed in the shaft mounting hole 52 by installing the bearing 103, the support column 101 will rotate in the shaft mounting hole 52, and each synchronous pulley 104 is meshed with the toothed belt 8, thereby driving multiple support columns 101 to rotate simultaneously through the toothed belt 8.

[0047] In this embodiment, a lifting support plate 6 is provided below the driving support rod 10, and the lifting support plate 6 has a center plate 61 located in the middle position and edge plates 62 located on both sides, and the center plate 61 and the edge plates 62 are respectively located below the bottom support plate 51, and through holes corresponding to the support columns 101 are also opened in the center plate 61 and the edge plates 62.

[0048] Specifically, the bottom of each support column 101 is integrally provided with a threaded column 102, and one end of each threaded column 102 away from the support column 101 is threadedly matched with a threaded sleeve 63, and the threaded sleeve 63 is respectively fixed on the center plate 61 and the edge plate 62 in a rectangular array, and the mounting bearing 103 corresponds to the through holes on the center plate 61 and the edge plate 62;

[0049] By adopting the above technical solution, when the toothed belt 8 mobilizes multiple set support columns 101 to rotate simultaneously, the threaded column 102 at the bottom of the support column 101 cooperates with the threaded sleeve 63, and the threaded cooperation at the connection pushes the center plate 61 and the edge plate 62 to rise and fall simultaneously. When descending, the lifting support plate 6 and the driving support rod 10 cooperate to lift the bracket 5 until the universal wheel 7 is separated from the ground, and the multiple set driving support rods 10 will evenly distribute the load on the bracket 5, thereby increasing the load-bearing performance of the switch cabinet bracket, and can also prevent the connection between the universal wheel 7 and the bracket 5 from being damaged.

[0050] An adjusting turntable 9 is movably connected in the mounting groove 56, and the adjusting turntable 9 has an anti-skid turntable 91 and a driving pulley 92 which are arranged in an integrated manner, wherein the driving pulley 92 is located above the anti-skid turntable 91, and the driving pulley 92 is meshed with the toothed belt 8, while the anti-skid turntable 91 is located below the toothed belt 8, and one side of the anti-skid turntable 91 extends to the side of the bottom support plate 51;

[0051] By adopting the above technical solution, since the anti-skid turntable 91 and the driving pulley 92 are integrally arranged, the worker only needs to rotate the anti-skid turntable 91, and through the mutual engagement of the driving pulley 92 and the toothed belt 8, the toothed belt 8 is driven to move on the inner side of the belt groove 53, thereby driving all the support columns 101 to rotate synchronously, without the need for separate adjustment, thus saving a lot of time, and when the support column 101 is rotated, there is no need to remove the switch cabinet from above the bottom pallet 51, so it is more convenient for workers to move the switch cabinet.

[0052] In this embodiment, the upper portion of the driving pulley 92 is movably connected to the cover plate 4 via a bearing, the toothed belt 8 is located below the cover plate 4, and the top of the steering wheel 55 is movably connected to the cover plate 4 via a pin shaft.

[0053] In this embodiment, the universal wheel 7 is located between the center plate 61 and the edge plate 62 , and the universal wheel 7 can rotate between the center plate 61 and the edge plate 62 .

[0054] In this embodiment, the switch cabinet comprises an incoming cabinet 1, a control cabinet 2 and an outgoing cabinet 3, and the incoming cabinet 1, the control cabinet 2 and the outgoing cabinet 3 are fixedly connected in sequence from left to right, and the bottoms of the incoming cabinet 1, the control cabinet 2 and the outgoing cabinet 3 are fixedly connected to the cover plate 4 respectively.

[0055] The working principle of the present invention is as follows: when in use, the switch cabinet is first fixed to the cover plate 4, so that the switch cabinet is installed above the bracket 5, and then the position of the bracket 5 is adjusted by the universal wheel 7, and then the position of the switch cabinet is adjusted. After moving to the appropriate position, the staff rotates the anti-skid turntable 91. Since the anti-skid turntable 91 and the driving pulley 92 are integrally arranged, the anti-skid turntable 91 will drive the driving pulley 92 to rotate, and the driving pulley 92 and the toothed belt 8 are meshed with each other, so that the movable toothed belt 8 moves on the inner side of the placement groove 53, and when the toothed belt 8 moves, the toothed belt 8 and the synchronous pulley 104 are meshed with each other, so that the synchronous pulley 104 drives the support column 101 to rotate. The bearing 103 is installed in the shaft mounting hole 52, so the support column 101 will rotate in the shaft mounting hole 52, and each of the synchronous pulleys 104 is meshed with the toothed belt 8, so that the multiple support columns 101 are driven to rotate simultaneously through the toothed belt 8. At this time, through the threaded cooperation between the threaded column 102 at the bottom of the support column 101 and the threaded sleeve 63, the center plate 61 and the edge plate 62 are synchronously lowered until the lifting bracket 6 and the driving support rod 10 cooperate to lift the bracket 5. At this time, the universal wheel 7 is separated from the ground, and the multiple driving support rods 10 set will evenly distribute the load on the bracket 5, thereby increasing the load-bearing performance of the switch cabinet bracket, and can also prevent the connection between the universal wheel 7 and the bracket 5 from being damaged;

[0056] After completing the above adjustment, the operator presses down the anti-skid turntable 91 so that the positioning slot 912 is connected with the positioning tooth 57 at the position of the installation groove 56. After reaching the bottom, the operator rotates the fastening base 910. At this time, the second thread 911 on the inner wall of the fastening base 910 is connected with the first thread 58 at the position of the installation groove 56 to fix it. At the same time, the driving pulley 92 at the top of the anti-skid turntable 91 moves downward synchronously, driving the limit block 93 at its top to engage with the toothed belt 8, thereby preventing the support column 101 from falling due to the overall weight, thereby maintaining the current state;

[0057] On the other hand, to release this state, it is only necessary to rotate the fastening base 910 in the opposite direction. At this time, the second thread 911 is separated from the first thread 58. Under the action of the spring 914, the anti-slip turntable 91 will move upward according to its elastic properties. Finally, the toothed belt 8 and the driving pulley 92 are engaged, and the adjustment process is carried out again.

[0058] The embodiments of the present invention disclose preferred embodiments, but are not limited thereto. A person skilled in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not deviate from the spirit of the present invention, they are all within the protection scope of the present invention.
