Description

Technical Field

[0001] The utility model relates to the technical field of transmission cabinet maintenance tools, in particular to an auxiliary tool for facilitating the disassembly and assembly of a transmission cabinet. Background Art

[0002] The transmission cabinet, also known as the transmission control cabinet, is a device used to control the operation of the motor. It is mainly composed of two parts: electronic control components and a casing. It can start, stop, forward and reverse the motor and other control actions. It is an indispensable equipment in industrial production. The transmission control cabinet is widely used in petrochemical, pharmaceutical, metallurgical, textile, electric power and other fields.

[0003] Some screws of the inverter unit of the transmission cabinet are not particularly convenient to disassemble and assemble. First, the busbar screws are too tight and cannot be unscrewed or tightened using ordinary sockets. Second, some screws are blocked by the cabinet body and cannot be tightened, which makes it take more time to tighten the screws during emergency repairs.

[0004] For example, in a Chinese patent with publication number CN112563939A, an outdoor electrical control cabinet that is easy to disassemble and fix is ​​provided, including a control cabinet, a bottom plate is connected to the bottom end of the control cabinet, a mounting structure is set up below the bottom plate, a plug plate is connected inside the mounting structure, an adjustment structure is connected to the bottom side wall of the mounting structure, a lifting rod is set up in the adjustment structure, a placement base is connected to the end of the adjustment structure away from the mounting structure, an auxiliary structure is connected to one side wall of the control cabinet, and a hook is connected to the card plate to hang the control cabinet on the wall. When disassembly is required, the control cabinet only needs to be lifted up to separate the hook from the card plate. Due to the characteristics of the threaded connection, when the screw is rotated, The movement of the plug board can be controlled. By plugging the plug board into the slot, the control cabinet can be firmly connected to the mounting plate, thereby completing the installation of the control cabinet. When disassembly is required, only the screw needs to be reversed to pull the plug board out of the slot. However, when part of the inverter unit in the transmission cabinet is damaged, the staff needs to disassemble the damaged inverter unit alone. At this time, since the interior of the transmission cabinet is relatively narrow, when some screws are close to the cabinet body, it is inconvenient to disassemble the screws, and the efficiency is low. At the same time, when the disassembly action is large, the hand will inevitably hit the components inside the transmission cabinet, causing bruises or scratches on the hand, making it easy for the staff to be injured at work, and there are certain safety hazards.

[0022] In order to more clearly understand the technical means of the utility model and implement it according to the contents of the specification, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0023] See attached Figure 1-4 As shown, an auxiliary tool for facilitating the disassembly and assembly of a transmission cabinet in the first embodiment includes: a support column 1 and a transmission rod 4; a rotating cavity 11 is opened in the support column 1, and a rotating rod 2 which can rotate around the center of the support column 1 as an axis is provided inside the rotating cavity 11, and the top of the rotating rod 2 extends upward to the outside of the support column 1, and a support plate 3 is fixedly installed on one side of the top of the support column 1, and a connecting component is provided on the surface of the support plate 3; the connecting component includes a connecting seat 5 arranged on the support plate 3, and a sleeve 54 is detachably provided on the top of the connecting seat 5.

[0024] A mounting block 55 is fixedly installed at the bottom of the sleeve 54, a mounting groove compatible with the mounting block 55 is opened inside the connecting seat 5, a magnet 51 that can assist in fixing the mounting block 55 is provided on the inner wall of the connecting seat 5, and the internal thread of the mounting block 55 is connected with a bolt, and a threaded hole compatible with the bolt is opened on the surface of the connecting seat 5, and the mounting block 55 is detachably connected to the connecting seat 5 through the bolts.

[0025] By disassembling the sleeve 54, when there are different screw specifications inside the transmission cabinet, the fixing of the mounting block 55 can be released by the screws, and then the sleeve 54 can be taken out for replacement. The sleeve 54 can be replaced and adjusted to increase the applicability of the tool.

[0026] The bottom end of the connecting seat 5 is rotatably connected to a sliding seat 52, the top of the rotating rod 2 is fixedly installed with a lower transmission shaft 14, the top of the lower transmission shaft 14 is provided with a universal joint 13, and the other end of the universal joint 13 is provided with an upper transmission shaft 53, the top of the upper transmission shaft 53 passes through the sliding seat 52 and is fixedly connected to the bottom end of the connecting seat 5, the sliding seat 52 is slidably connected to the support plate 3, and the surface of the support plate 3 is provided with a damping groove for the movement of the sliding seat 52, and the damping groove is arranged in a semi-arc shape.

[0027] Through the semi-arc setting of the damping slide groove, when the position of the screw inside the transmission cabinet is relatively high, the sliding seat 52 can be slid to make the sliding seat 52 slide on the damping slide groove, and rotate and adjust around the universal joint 13. Then the sleeve 54 is put on the nut, and the rotating rod 2 is rotated. Through the transmission of the universal joint 13, the upper transmission shaft 53 drives the connecting seat 5 to rotate around the axis of the connecting seat 5 itself, thereby realizing the function of the sleeve 54 to loosen and disassemble the screw.

[0028] The bottom end of the rotating rod 2 extends downward to the outside of the supporting column 1 , and a transmission rod 4 is fixedly mounted on the bottom end of the rotating rod 2 , and handles 7 are provided at both ends of the transmission rod 4 .

[0029] By setting the handle 7, when the screw needs to be removed, lift the support column 1, align the sleeve 54 with the nut on the screw, then put the sleeve 54 on the nut, and then apply a certain force to one side of the handle 7 with one hand. At this time, the other hand tightly holds the support column 1, and then applies a certain force to one side of the handle 7, so that the handle 7 drives the transmission rod 4 to rotate around the rotating rod 2 as the center, and then the rotating rod 2 drives the connecting seat 5 to rotate through the universal joint 13, so that the connecting seat 5 drives the sleeve 54 to rotate around itself as the axis, so that the sleeve 54 loosens the nut on the screw, and then the screw is removed.

[0030] An adjustment cavity 42 is provided inside the transmission rod 4, and an adjustment component capable of adjusting the length of the handle 7 is provided inside the adjustment cavity 42. The adjustment component includes an adjustment rod 6, and a sliding groove for horizontal movement of the adjustment rod 6 is provided on the inner wall of the adjustment cavity 42. One end of the adjustment rod 6 extends to the outside of the transmission rod 4, and the end of the adjustment rod 6 located outside the transmission rod 4 is fixedly connected to the handle 7.

[0031] The adjustment component also includes an active cavity opened inside the adjustment rod 6, and the inner cavity of the adjustment rod 6 is rotatably and laterally provided with a support rod 63, the surface of the support rod 63 is rotatably connected to the limiting rod 61, and a pressing piece is provided on the upper surface of one end of the limiting rod 61, and a support spring 62 is telescopically and vertically provided between the upper surface of the other end of the limiting rod 61 and the inner wall of the adjustment rod 6, and a limiting block 64 is provided on the lower surface of the limiting rod 61 and at a corresponding position of the support spring 62, and a plurality of limiting grooves 41 for matching the limiting blocks 64 are provided on the inner wall of the adjustment cavity 42 at intervals along the horizontal direction.

[0032] When the screw to be twisted is deeper, the pressing piece is pressed down, so that one end of the limit rod 61 is forced to move downward, and the limit rod 61 rotates around the support rod 63. Then the other end of the limit rod 61 moves upward and squeezes the support spring 62, so that the support spring 62 contracts and generates elastic force. Then the limit rod 61 drives the limit block 64 to disengage from the limit groove 41. At this time, pulling the handle 7 outward can drive the adjustment rod 6 to move outward, so that the length of the handle 7 can be adjusted so that the staff can better turn the rotating rod 2.

[0033] Furthermore, the limiting rod 61 is rotatably connected to the support rod 63 via a bearing, and both ends of the adjusting rod 6 are provided with openings for the pressing member and the limiting block 64 to move, and the surface of the handle 7 is provided with a flexible grip sleeve.

[0034] By providing the bearing, the limiting rod 61 is made more flexible when rotating, and the limiting rod 61 and the supporting rod 63 are prevented from directly contacting each other, which would cause the limiting rod 61 to have a larger friction force when rotating, thus making the rotation more strenuous.

[0035] Furthermore, the diameter of the handle 7 is the same as the diameter of the transmission rod 4 , and the bottom of the support column 1 is opened.

[0036] Furthermore, the rotating rod 2 is rotatably connected to the support column 1 through a bearing, and a sleeve 12 is provided on the surface of the support column 1. By providing the sleeve 12, it is convenient for a staff member to hold the area of ​​the sleeve 12 with one hand to fix the support column 1, and then rotate the handle 7 with the other hand, so that the handle 7 drives the transmission rod 4 to rotate about the central axis of the rotating rod 2.

[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
