Description

Technical Field

[0001] The invention belongs to the technical field of switch cabinet CT replacement auxiliary equipment, and in particular relates to a switch cabinet CT disassembly and assembly equipment and a use method thereof. Background Art

[0002] The magnitude of the current in the power generation, transformation, transmission, distribution and power consumption lines varies greatly, ranging from a few amperes to tens of thousands of amperes. In order to facilitate measurement, protection and control, it needs to be converted into a relatively uniform current. The current transformer (abbreviated as "CT") plays the role of converting and electrically isolating the current. At present, the CT of the switch cabinet in the system is arranged on the top or front and back sides of its cable room. When replacing the switch cabinet CT (current transformer), multiple people are required to cooperate with each other. After removing the relevant drainage busbars and line joints, there are special people to support it. The operator holds the CT upward at the bottom of the cable room, and other personnel also need to squeeze into the cable room to cooperate with the removal of the CT fixing bolts and then work together to move it out of the cabinet. It is time-consuming and laborious. Improper operation can easily damage the current transformer and injure the staff. Therefore The existing problems in the disassembly and assembly process of the switch cabinet CT are: the switch cabinet space is small, and multiple people are required to cooperate in the CT disassembly and assembly work, which is inconvenient and difficult to operate. Moreover, someone needs to lift the CT during disassembly, and other operators need to perform the disassembly, which requires the cooperation of multiple people, low work efficiency, and time-consuming and labor-intensive. In addition, due to the high labor intensity, it is not easy for the operators who lift the CT to persist for a long time, and they need to take multiple breaks and adjust before lifting again, resulting in time-consuming and labor-intensive disassembly, a long maintenance time, low work efficiency, and safety accidents may occur due to physical exhaustion of the lifters, resulting in low safety. Therefore, it is very necessary to provide a switch cabinet CT disassembly and assembly equipment and a method of use that has a reasonable structure, flexible and convenient operation, saves time and effort, does not require the cooperation of multiple people, and is safe and reliable.

DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with the accompanying drawings. Example 1

[0024] like Figure 1-7 As shown, a switch cabinet CT disassembly and assembly equipment comprises a mobile chassis 1 and a clamping and lifting mechanism 7, wherein a lifting mechanism 2 which is installed on the mobile chassis 1 in a telescopic connection manner is arranged above the mobile chassis 1, an angle adjustment mechanism 3 is arranged on the top of the lifting mechanism 2, a translation mechanism 4 is arranged above the angle adjustment mechanism 3, a bottom plate 5 is installed inside the translation mechanism 4, a single-axis moving platform 6 is installed above the bottom plate 5, a clamping and lifting mechanism 7 is installed above the single-axis moving platform 6, the clamping and lifting mechanism 7 is located inside a current transformer body 8 to realize the operation of clamping the current transformer body 8, and cooperates with the lifting mechanism 2, the angle adjustment mechanism 3, the translation mechanism 4 and the single-axis moving platform 6 to realize the height adjustment, angle adjustment and multi-directional horizontal movement adjustment of the current transformer body 8, so as to facilitate the disassembly and assembly of the current transformer body 8.

[0025] The mobile base frame 1 includes a multi-rod mobile frame 11, and the free ends of the multi-rod mobile frame 11 are each provided with a universal wheel seat 12, and the universal wheel seat 12 is equipped with a self-locking universal wheel 13. The inner connecting part of the multi-rod mobile frame 11 is provided with a vertically upward sleeve 14, and a longitudinal groove 15 is opened on one side of the sleeve 14.

[0026] The lifting mechanism 2 includes a lifting rod 21 located inside the sleeve 14 and slidably connected to the sleeve 14 . A tooth plate 22 is provided on one side of the lifting rod 21 corresponding to the longitudinal slot 15 and the tooth plate 22 extends out of the longitudinal slot 15 .

[0027] The lifting mechanism 2 also includes a locking sleeve 23 of a clamp-type structure located outside the sleeve 14, and the opening end of the locking sleeve 23 is provided with a rotating shaft seat 24. The rotating shaft seat 24 is provided with a driving roller 25 that meshes with the tooth plate 22 for transmission. The driving roller 25 is axially connected to the handle 26.

[0028] In this embodiment, the driving roller and tooth plate adopt TCG rack (standard type) CRE&CPA series. The CRE series and CRA / CRC series share the same roller CPA; TCG rack, through the rolling engagement of the roller pin and the rack tooth surface, realizes a lighter rotary-linear transmission; the gap of the meshing part can be eliminated by pre-pressure adjustment to achieve zero backlash transmission; rolling engagement can minimize the collision and friction between metal parts, achieve low wear, low dust generation and good maintenance-free performance; high-precision rack splicing can be easily achieved, which is more convenient for long-stroke mechanical transmission; The working principle of the lifting mechanism is: when the CT needs to be lifted, just turn the handle, the handle drives the driving roller to rotate, the driving roller drives the tooth plate to move, and then drives the lifting rod to move up and down along the inner wall of the sleeve, so as to achieve flexible lifting and lowering, and lift the CT to the required height. Manually adjusting the handle is convenient for controlling the lifting height position (in actual users, electric devices can also be used instead of manual operation), which can ensure stable and reliable lifting of the CT, and does not require other operators to lift the CT from the side. Therefore, only one operator needs to enter the cabinet to install the CT, which is very suitable for the installation and disassembly of CT in narrow switch cabinets.

An adjustment arc groove 34 is opened below the adjustment plate 32, and an adjustment screw 35 that passes through the push rod 31 is provided inside the adjustment arc groove 34.

[0030] In this embodiment, the working principle of the angle adjustment mechanism is: the flexible direction adjustment of the angle adjustment mechanism is realized by cooperating with the adjustment plate, the push rod and the shaft pin.

Both ends of the optical rod 66 are connected to the side opening frame 61 through guide shaft supports 67.

[0033] The movable fixed fixture table 68 is located on the upper part of the side opening frame 61, and includes a base plate 81. The base plate 81 is slidably connected to the corresponding light rod 66 through a group of linear bearings 69. The base plate 81 is transmission connected to the lead screw 65 through the lead screw 601. A side clamp 82 is arranged above the base plate 81. A mounting plate 83 for connecting the clamping and lifting mechanism 7 is arranged in front of the side clamp 82. Both ends of the mounting plate 83 are fixedly connected to the side clamp 82 through an elbow-type quick fixing clamp 84 arranged on the side clamp 82.

[0034] In this embodiment, the guide shaft support adopts the STHWSBL12b open and extended guide shaft support; the lead screw adopts the MTSRC12-600-T2-Q7-S2-E4 30-degree trapezoidal lead screw; the coupling adopts the MCGSC32-12-12 type; the lead screw adopts the MTSBHR12 type widened square nut lead screw seat; the linear bearing adopts the LHBB-MX12 type linear bearing with a lubricated support; the elbow-type quick fixing clamp adopts the MC01-1 elbow clamp.

[0035] The working principle of the single-axis mobile platform is as follows: the hydraulic cylinder of the clamping and lifting mechanism is installed on the mounting plate, and the mounting plate is reliably and firmly fixed by a set of elbow-type quick-fix clamps to complete the installation of the clamping and lifting mechanism and the single-axis mobile platform, and then the stepper motor is started. The stepper motor drives the lead screw to rotate through the coupling, and the lead screw drives the mobile fixed fixture table to move horizontally through the lead screw. During the lateral translation of the mobile fixed fixture table, it moves synchronously along the light rod through the linear bearing to ensure the smooth and reliable displacement of the mobile fixed fixture table.

The free end of the transverse tie rod 73 is installed with an arc-shaped inner support plate 77, and the arc-shaped inner support plate 77 is connected to the transverse tie rod 73 through a group of ribs 78.

[0037] In this embodiment, the working principle of the clamping and lifting mechanism is: start the hydraulic cylinder, the hydraulic cylinder pushes and pulls the connecting rod through the hydraulic rod, the connecting rod drives the transverse tie rods on both sides to rotate around the shaft rod, thereby realizing the transverse tie rods on both sides to move closer to or away from each other, thereby driving the arc-shaped inner support plates on both sides to move accordingly, thereby realizing the tightening and relaxation of the inner wall of the current transformer body, thereby realizing the clamping operation of the current transformer body, and facilitating the disassembly and assembly of the current transformer body.
