Description

Technical Field

[0001] The utility model belongs to the field of mechanical production auxiliary equipment, and specifically provides an assembly workbench for a switch cabinet. Background Art

[0002] Switchgear is an important power equipment, mainly used for switching and control of medium voltage power system. It is mainly composed of cabinet and circuit breaker, with functions such as overhead incoming and outgoing lines, cable incoming and outgoing lines, busbar connection, etc. The cabinet is composed of shell, electrical components (including insulation parts), various mechanisms, secondary terminals and connections.

[0003] In the prior art, the production and assembly of medium-voltage switchgear such as TGP and TGS are all carried out on simple fixed flat workbenches. Workers need to work around the workbench, and assembly at high and low places is extremely inconvenient. At the same time, the workbench surface is not on the same plane as the loading surface of the existing transfer vehicle. After the medium-voltage switchgear is assembled, multiple workers are often required to lift the switchgear onto the transfer vehicle together, which is time-consuming and labor-intensive, and is also prone to safety hazards.

[0004] Therefore, there is an urgent need for a switch cabinet assembly workbench that is convenient for workers to assemble and carry the switch cabinet. Utility Model Content

[0005] The utility model provides an assembly workbench for a switch cabinet, which is particularly suitable for the assembly of a medium-voltage switch cabinet. It can greatly optimize the operating experience of workers when assembling the switch cabinet, reduce labor intensity, and can also be adapted to existing transfer tooling vehicles to facilitate the transportation of assembled switch cabinets.

[0006] The technical solution of the utility model is as follows:

[0007] An assembly workbench for a switch cabinet comprises a base, a vertical lifting component is arranged at the center of the base, a workbench is arranged at the output end of the lifting component, a linear guide rail is vertically arranged on the base, a sliding block is fixedly connected to the bottom surface of the workbench through a sliding column, and the sliding block slides on the linear guide rail.

[0008] In this solution, the lifting and lowering of the workbench is controlled by the lifting assembly, and the linear guide rail plays a lifting and guiding role while also having sufficient torsion resistance. Workers assemble the switch cabinet on the liftable workbench, and can freely adjust the installation plane through the lifting assembly, which makes assembly more convenient; at the same time, after the assembly is completed, the height of the workbench surface can be adjusted to be consistent with the loading surface height of the transfer vehicle, and the switch cabinet can be directly pushed into the transfer vehicle, which is efficient and fast, and effectively reduces labor intensity.

[0009] Preferably, the workbench includes a lifting end and a working end, the center of the lifting end is fixedly connected to the output end of the lifting assembly, a roller assembly is provided on the lifting end, the roller assembly abuts against the bottom of the working end, and the center of the working end is horizontally rotatably connected to the center of the lifting end.

[0010] In this solution, the working end can rotate relative to the lifting end. During the assembly of the switch cabinet, the switch cabinet can be rotated by rotating the working end to assemble the sides and back. Workers do not need to hold parts around the workbench for assembly, which greatly increases the convenience of installation and reduces labor intensity.

[0011] Preferably, a limited support block is provided on the upper surface of the base.

[0012] In this solution, a limit block is provided on the upper surface of the base to limit the minimum height to which the workbench can be lowered, thereby preventing components on the bottom of the workbench from colliding and being damaged with the upper surface of the base during the lowering process.

[0013] Preferably, the roller assembly comprises a horizontally arranged support shaft and a rotating bearing passing through the support shaft, and the roller assembly is arranged in an array along the central circumference of the lifting end.

[0014] In this solution, the roller assembly not only supports the working end, but also makes the working end rotate more smoothly, ensuring that the working surface is always stable during rotation.

[0015] Preferably, the working end is a cylindrical structure. The working end is set as a cylindrical structure to avoid the corners from injuring workers or bumping against other parts when the working end is rotated during the assembly process.

[0016] It should be noted that, since the switch cabinet needs to be pushed onto the transfer vehicle after assembly, the working surface of the workbench has a certain friction, and it will be difficult to push. In order to solve this problem, preferably, the working end includes a rotating bottom surface and a working surface, and the rotating bottom surface and the center of the working surface are hinged. A slider is provided on one side of the rotating bottom surface, and the lower surface and upper surface of the slider respectively abut between the rotating bottom surface and the working surface, and slide along the radius of the rotating bottom surface. On the sliding path of the slider, the distance between the rotating bottom surface and the working surface gradually decreases, and the slider slides toward the center of the rotating bottom surface, and the working surface tilts.

[0017] In this solution, when workers need to push the assembled switch cabinet onto the operating tooling vehicle, they rotate the screw to make the slider slide toward the center of the rotating bottom surface, and the slider presses the working surface upward. Since the center of the working surface is hinged to the rotating bottom surface, the working surface will have a certain inclination. By rotating the working end, the lowest end of the working surface is placed on the operating tooling vehicle. Due to the downward inclination angle, the switch cabinet is easier to push, thereby reducing the work intensity of the workers.

[0018] Preferably, support columns are evenly arranged on a side of the rotating bottom surface away from the sliding block, and holes corresponding to the support columns are arranged on the working surface.

[0019] In this scheme, in order to prevent the workbench from having limited load-bearing capacity and uneven force causing the work surface to tilt when assembling the switch cabinet, support columns are provided to provide auxiliary support to the work surface. At the same time, when transporting the switch cabinet, the work surface can be tilted so that the support columns can extend out of the work surface to support the switch cabinet instead of the work surface. The contact area between a single support column and the bottom of the switch cabinet is small, so the friction is small, making the switch cabinet easier to push.

[0020] Preferably, the height of the support column is flush with the height of the working surface when it is not tilted, sharing the load of the working surface. At the same time, when the working surface is tilted, it is ensured that only a slight tilt is required to expose the support column for support, thereby reducing the force required for the sliding end of the slider.

[0021] Preferably, the rotating bottom surface is evenly provided with a plurality of support blocks on the side of the slider to support the working surface, increase the force bearing capacity of the side of the slider, and prevent the working surface from tilting in other directions.

[0022] Preferably, the upper surface of the support column is hemispherical, which further reduces the friction force when the support column supports the switch cabinet;

[0023] Since the support columns are all on the same horizontal plane, and half of the bottom of the switch cabinet is an inclined working surface, the switch cabinet may also be tilted. However, when the inclination angle of the working surface is too large, the bottom surface of the switch cabinet and the circumference of the support column are likely to interfere with each other. Therefore, preferably, the inclination angle α of the working surface does not exceed 3°. Since the height of the support column is flush with the height of the working surface when it is not inclined, a slight inclination of the working surface can expose the support column to support the switch cabinet, which is also convenient for pushing; at the same time, it can also avoid that the holes set on the working surface and the support column are too large, and a large gap is generated between the support column.

[0024] Beneficial effects of the utility model:

[0025] The utility model controls the lifting of the workbench through the lifting component, and the linear guide rail plays a lifting and guiding role while also having sufficient torsion resistance. Workers assemble the switch cabinet on the liftable workbench, and can freely adjust the installation plane through the lifting component, which makes it more convenient to assemble; at the same time, after the assembly is completed, the height of the workbench surface can be adjusted to be consistent with the loading surface height of the transfer vehicle, and the switch cabinet can be directly pushed into the transfer vehicle, which is efficient and fast, and effectively reduces labor intensity.

DETAILED DESCRIPTION

[0034] In conjunction with the accompanying drawings, the technical solution of the present invention is clearly and completely described through the specific implementation methods of the embodiments of the present invention.

[0035] Embodiment 1:

[0036] like Figure 1 and Figure 2 An assembly workbench 2 of a switch cabinet shown in the figure comprises a base 1, a vertical lifting component 11 is arranged at the center of the base 1, a workbench 2 is arranged at the output end of the lifting component 11, a linear guide rail 23 is vertically arranged on the base 1, and a sliding block 22 is fixedly connected to the bottom surface of the workbench 2 through a sliding column 21, and the sliding block 22 slides on the linear guide rail 23.

[0037] Specifically, since the assembled switch cabinet has a certain weight, the lifting component 11 can select the lifting cylinder of the external pump station to apply force. A manual switch 14 can be set next to the base 1 to control the lifting range of the lifting cylinder. At the same time, multiple linear guides 23 are evenly arranged on the base 1 to ensure the stability of the workbench 2 and prevent eccentricity during up and down movements. The lifting and lowering of the workbench 2 is controlled by the lifting component 11. The linear guide 23 not only plays a lifting and guiding role, but also has sufficient torsion resistance. Workers assemble the switch cabinet on the liftable workbench 2, and can freely adjust the installation plane through the lifting component 11, which can make assembly more convenient; at the same time, after the assembly is completed, the table height of the workbench 2 can be adjusted to be consistent with the loading surface height of the transfer vehicle, so that the switch cabinet can be directly pushed into the transfer vehicle, which is efficient and fast, and effectively reduces labor intensity.

[0038] Furthermore, the workbench 2 includes a lifting end 24 and a working end 25. The center of the lifting end 24 is fixedly connected to the output end of the lifting assembly 11. A roller assembly 26 is provided on the lifting end 24. The roller assembly 26 abuts against the bottom of the working end 25. The center of the working end 25 is horizontally rotatably connected to the center of the lifting end 24.

[0039] Specifically, the roller assembly 26 includes a horizontally arranged support shaft 261 and a rotating bearing passing through the support shaft 261. The roller assembly 26 is arranged in an array along the central circumference of the lifting end 24. The roller assembly 26 not only supports the working end 25, but also makes the working end 25 rotate more smoothly, ensuring that the working surface 252 is always stable during rotation. The lifting end 24 is provided with a tapered roller bearing, and the rotating shaft is assembled from standard aluminum profiles and connected to the working end 25 by bolts to facilitate subsequent adjustment and movement.

[0040] Furthermore, a limit support block 13 is provided on the upper surface of the base 1. The limit block is provided on the upper surface of the base 1 to limit the minimum height of the workbench 2 to ensure the accuracy of the return and avoid the collision and damage of the components on the bottom of the workbench 2 and the upper surface of the base 1 during the lowering process.

[0041] Furthermore, the working end 25 can be in any shape, preferably a cylindrical structure. The working end 25 is set as a cylindrical structure to avoid the corners from injuring workers or bumping against other parts when the working end 25 is rotated during the assembly process.

[0042] Embodiment 2:

[0043] In the first embodiment, since the switch cabinet needs to be pushed onto the transfer vehicle after assembly, the working surface 252 of the workbench 2 has a certain friction force, and pushing it will be more difficult. Figures 3 to 5 As shown, an improved structure of a working end 25 is provided. The working end 25 comprises a rotating bottom surface 251 and a working surface 252, wherein the rotating bottom surface 251 and the working surface 252 are hinged at their centers, and a slider 27 is provided on one side of the rotating bottom surface 251, wherein the lower surface and the upper surface of the slider 27 abut between the rotating bottom surface 251 and the working surface 252 respectively, and slide along the radius of the rotating bottom surface 251, and the distance between the rotating bottom surface 251 and the working surface 252 gradually decreases on the sliding path of the slider 27, and the working surface 252 is tilted when the slider 27 slides toward the center of the rotating bottom surface 251.

[0044] Specifically, the center hinge of the rotating bottom surface 251 and the working surface 252 can be connected by a joint bearing. When the worker needs to push the assembled switch cabinet onto the operating tooling vehicle, the slider 27 slides toward the center of the rotating bottom surface 251, and the slider 27 presses the working surface 252 upward. Since the center of the working surface 252 is hinged to the rotating bottom surface 251, the working surface 252 will have a certain inclination. By rotating the working end 25, the lowest end of the working surface 252 is placed on the operating tooling vehicle. Due to the downward inclination angle, the switch cabinet is easier to push, thereby reducing the work intensity of the workers.

[0045] The slider 27 can be a screw slider, which is guided and driven by a screw guide rail fixed on the rotating bottom surface 251. The worker controls the rotation of the screw 253 by turning the rotating handle 255 exposed outside the working end 25, thereby controlling the sliding of the slider 27. The part where the slider 27 contacts the working surface 252 is a spherical structure, which can adapt to the angle of the deflection of the working surface 252. It should be noted that a locking structure (not shown in the figure) is provided on the slider 27 and the rotating bottom surface 251, and the locking structure can be a bolt locking, etc.

[0046] Furthermore, in order to ensure the overall stability of the working end 25 and to prevent the working surface 252 from tilting due to uneven force due to limited load-bearing capacity of the workbench 2 when assembling the switch cabinet, support columns 28 are evenly arranged on the side of the rotating bottom surface 251 away from the slider 27, and holes corresponding to the support columns 28 are arranged on the working surface 252. The support columns 28 are arranged to provide auxiliary support for the working surface 252; at the same time, when the switch cabinet is transported, the support columns 28 can be extended out of the working surface 252 by tilting the working surface 252, and the working surface 252 can be used to support the switch cabinet. The contact area between a single support column 28 and the bottom of the switch cabinet is small, and the friction is small, so that the switch cabinet is easier to be pushed.

[0047] Furthermore, the height of the support column 28 is flush with the height of the working surface 252 when it is not tilted, sharing the load of the working surface 252. At the same time, when the working surface 252 is tilted, it is ensured that only a slight tilt is required to expose the support column 28 for support, thereby reducing the force required for the end of the slider 27 to slide. The rotating bottom surface 251 is evenly provided with a plurality of support blocks 29 on the side of the slider 27 to support the working surface 252, increase the force bearing capacity of the side of the slider 27, and prevent the working surface 252 from tilting in other directions. At the same time, an elastic member 254 is provided on the rotating bottom surface 251 on the side away from the slider 27 to provide an upward elastic force for the working surface 252. In addition, a buffer pad can be provided at the bottom of the rotating bottom surface 251 on the side away from the slider 27 to buffer the force when the switch cabinet is transported, thereby preventing the working end 25 from being deformed or damaged due to excessive force. It should be noted that the upper surface of the support column 28 is hemispherical, which further reduces the friction when the support column 28 supports the switch cabinet, and also reduces the possibility of interference between the bottom edges and corners of the switch cabinet and the support column 28 when the switch cabinet is tilted.

[0048] Furthermore, since the support columns 28 are all in the same horizontal plane and half of the bottom of the switch cabinet is an inclined working surface 252, the switch cabinet may also tilt. However, when the inclination angle α of the working surface 252 is too large, interference is likely to occur between the bottom surface of the switch cabinet and the support columns 28 in the circumferential direction.

[0049] Specifically, the inclination angle α of the working surface 252 does not exceed 3°. Since the height of the support column 28 is flush with the height of the working surface 252 when it is not inclined, a slight inclination of the working surface 252 can expose the support column 28 to support the switch cabinet, which is also convenient for implementation; at the same time, it can also avoid the holes on the working surface 252 that are directly arranged in opposition to the support column 28 being too large, resulting in a large gap between the support column 28.

[0050] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of protection claimed by the utility model.
