Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution cabinets and relates to a support for a power distribution cabinet, in particular to a support seat for a power distribution cabinet capable of changing height and adjusting balance. Background Art

[0002] With the accelerated development of the electrification era, the power distribution load in projects is getting bigger and bigger, and the components of the distribution cabinet are increasing. Due to the limitation of space, the distribution cabinet is getting heavier and heavier. When the foundation sinks and abnormal vibration occurs, it may cause the distribution cabinet to tilt, which can easily cause electrical accidents. In addition, due to the change of power distribution load, it is sometimes necessary to change the height of the distribution cabinet. The general engineering practice is to fix the channel steel on the ground and the distribution cabinet on its upper part, which cannot coordinate the weightlessness balance.

[0003] There is an urgent need for a distribution cabinet support that can adjust the balance and height when the foundation of the distribution cabinet settles, so as to avoid electrical accidents. Utility Model Content

[0004] The utility model aims to provide a distribution cabinet support seat capable of changing height and adjusting balance, so as to solve the problem of electrical accidents caused by foundation settlement of the distribution cabinet.

[0010] The thickness of the idler gear and the transmission gear b is greater than the thickness of the main gear a and the main gear b.

[0011] When in use, first place the scissor jack a and the scissor jack b on the ground, then assemble the transmission gear a, transmission gear b and pulley a, pulley b through the support shaft or welding, the main gear a, the main gear b are fixedly connected to the screw rods of the scissor jack a, the scissor jack b respectively, the main gear a, the idler gear and the transmission gear a are meshed with each other and then rotated and supported on the gear holder a which can be freely extended and retracted up and down, the main gear b and the transmission gear b are meshed and then rotated and supported on the gear holder b which can be freely extended and retracted up and down, and finally the conveyor belt is put on the pulley a and the pulley b.

[0012] If scissor jack a sinks, turn the screw of scissor jack a through the handle, and scissor jack a starts to rise. At the same time, the screw drives the main gear a to rotate, the main gear a drives the idler wheel to rotate, the idler wheel drives the transmission gear a to rotate, the transmission gear a and pulley a rotate synchronously, and the pulley a rotates during the rotation of the conveyor belt, which in turn drives the pulley b to start rotating, the pulley b and the transmission gear b rotate synchronously, the transmission gear b drives the main gear b to rotate, the main gear b and the screw of scissor jack b rotate synchronously, and scissor jack b starts to fall. At a certain moment, scissor jack a and scissor jack b achieve left-right balance and the horizontal height is consistent, and then stop rotating the screw of scissor jack a.

[0013] It is further preferred that the conveyor belt further comprises a pulley c, the conveyor belt is adjustable in length, and the idler wheel and the pulley c are coaxially fixed together. When in use, the scissor jack a and the scissor jack b achieve left-right balance, and after the horizontal heights are consistent, the conveyor belt is adjusted and put on the pulley c and the pulley b, and then the screw rod of the scissor jack a or the scissor jack b is rotated to achieve the increase and decrease of the overall height of the distribution cabinet.

[0014] Further preferably, if it is desired to accurately determine whether the scissor jack a and the scissor jack b are balanced, after visually checking the balance, an electronic mobile balance measuring device may be installed on the conveyor belt for precise measurement.

[0015] Further preferably, in order to better realize the rotation of the main gear a and the main gear b, the gear holder a rotates the screw rod supporting the scissor jack a through the threaded hole, and the gear holder b rotates the screw rod supporting the scissor jack b through the threaded hole.

[0024] The specific embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0025] The utility model discloses a distribution cabinet support seat for changing height and adjusting balance, comprising a scissor jack a11, a scissor jack b12, a main gear a21, a main gear b22, an idler gear 23, a transmission gear a24, a transmission gear b25, a pulley a and a pulley b.

The main gear a21 is meshed with the idler gear 23, and the idler gear 23 is meshed with the transmission gear a24. One side of the transmission gear a24 is coaxially fixed to the pulley a, and one side of the transmission gear b25 is coaxially fixed to the pulley b.

[0027] Pulley a and pulley b are connected by a conveyor belt 3, a transmission gear b25 is meshed with a main gear b22, and the main gear b22 is fixed to an end of a screw rod of a scissor jack b12 without a handle.

[0028] The main gear a21, the idler gear 23 and the transmission gear a24 are rotatably supported on a gear holder a26 which is freely retractable up and down, and the main gear b22 and the transmission gear b25 are rotatably supported on a gear holder b27 which is freely retractable up and down. Figure 1 As shown, the gear holder a26 and the gear holder b27 include a horizontal support rod and a vertical support rod. The horizontal support rod of the gear holder a26 rotatably supports the main gear a21, the idler gear 23 and the transmission gear a24, and the horizontal support rod of the gear holder b27 rotatably supports the main gear b22 and the transmission gear b25. The vertical support rods of the gear holder a26 and the gear holder b27 can be freely extended up and down in a manner similar to a telescopic antenna.

[0029] The thickness of the idler wheel 23 and the transmission gear b25 is greater than the thickness of the main gear a21 and the main gear b22. Preferably, the thickness of the idler wheel 23 and the transmission gear b25 is slightly greater than the screw stroke length of the scissors jack a11 and the scissors jack b12, so that during the movement of the utility model, the main gear a21 always remains in meshing with the idler wheel 23, and the main gear b22 always remains in meshing with the transmission gear b25.

[0030] Preferably, the idler gear 23 and the transmission gear a24 are rotationally connected to the gear holder a26 via a support shaft, and the transmission gear b25 is rotationally connected to the gear holder b27 via a support shaft.

[0031] Preferably, the main gear a21 is fixed together with the screw rod of the scissors-type jack a11, and the screw rod can be rotatably supported on the gear holder a26 through a smooth hole or a threaded hole; the main gear b22 is fixed together with the screw rod of the scissors-type jack b12, and the screw rod can be rotatably supported on the gear holder b27 through a smooth hole or a threaded hole.

[0033] When in use, first place the scissor jack a11 and the scissor jack b12 on the ground, then assemble the transmission gear a24, transmission gear b25 and pulley a and pulley b through a support shaft or welding, and fix the main gear a21 and the main gear b22 to the screw rods of the scissor jack a11 and the scissor jack b12 respectively, and then mesh the main gear a21, the idler gear 23 and the transmission gear a24 with each other and rotate and support them on the gear holder a26 which can be freely extended and retracted up and down, and then mesh the main gear b22 and the transmission gear b25 and rotate and support them on the gear holder b27 which can be freely extended and retracted up and down, and finally put the conveyor belt 3 on the pulley a and the pulley b.

[0034] If the scissor jack a11 sinks, the screw of the scissor jack a11 is rotated by the handle, and the scissor jack a11 starts to rise. At the same time, the screw drives the main gear a21 to rotate, the main gear a21 drives the idler wheel 23 to rotate, the idler wheel 23 drives the transmission gear a24 to rotate, the transmission gear a24 and the pulley a rotate synchronously, and the pulley a drives the conveyor belt 3 to move during the rotation of the pulley, and then drives the pulley b to start rotating, the pulley b and the transmission gear b25 rotate synchronously, the transmission gear b25 drives the main gear b22 to rotate, the main gear b22 and the screw of the scissor jack b12 rotate synchronously, and the scissor jack b12 starts to descend. At a certain moment, the scissor jack a11 and the scissor jack b12 achieve left-right balance and the same horizontal height, so that the scissor jack a11 and the scissor jack b12 are balanced, effectively solving the tilt of the distribution cabinet caused by unstable foundation and foundation vibration, thereby avoiding the occurrence of electrical accidents. At this time, the screw rod of the scissor jack a11 is stopped. If you want to accurately determine whether the left and right sides of the utility model are balanced, you can visually check the balance and then add an electronic mobile balance measuring device 4 to the conveyor belt 3 to accurately measure whether the scissor jacks on both sides are balanced.

[0035] Preferably, the scissor jack a11 and the scissor jack b12 achieve left-right balance, and after the horizontal height is consistent, the conveyor belt 3 is adjusted and put on the pulley c and the pulley b, and then the screw rod of the scissor jack a11 or the scissor jack b12 is rotated to achieve the increase and decrease of the overall height of the distribution cabinet. Due to the problem of space height, sometimes the height of the distribution cabinet needs to be changed, and now it can be achieved by adjusting the height of the scissor jack, avoiding manual removal of cables and moving the distribution cabinet, effectively saving funds and losses caused by power outages.
