Description

Technical Field

[0001] The present invention relates to the technical field of substation operation and maintenance, and in particular to an auxiliary lifting structure for power maintenance. Background Art

[0002] The substation operation and maintenance station is responsible for the management of the unmanned substations and the substations with few staff on duty, and is fully responsible for the operation and maintenance, switching operations, accident and abnormality handling, equipment inspections, and regular equipment testing and rotation of the substations under its jurisdiction. In substation operation and maintenance, staff often need to repair and check high-altitude power equipment. Therefore, an auxiliary lifting structure for power maintenance is needed.

[0003] Most of the existing auxiliary lifting structures for power maintenance use telescopic rods to drive the folding frame to rise and fall. However, the stability of one set of telescopic rods and folding frames is poor, and the staff cannot work safely on the lifting platform. Although the use of two sets of telescopic rods and folding frames can increase stability, the cost of two sets of telescopic rods is high, which is not conducive to mass production. Moreover, most of the existing lifting mechanisms for substation operation and maintenance still feel shaking after the rollers are fixed, which affects the work of the staff. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides an auxiliary lifting structure for electric power maintenance.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0006] An electric power maintenance auxiliary lifting structure comprises a base plate and a mounting frame arranged on the top of the base plate, wherein the bottom of the base plate is fixedly connected to a motor, one end of the motor output shaft vertically penetrates the base plate and the mounting frame in sequence and is fixedly connected to a worm, and the top of the mounting frame is rotatably connected to a rotating gear matched with the worm through a rotating frame, the number of the rotating gears is set to at least three, and they are evenly arranged on the outer periphery of the worm, the rotating shaft of the rotating gear is fixedly connected to an arc rod through a fixing frame, the outer end of the arc rod is rotatably connected to a linkage rod, and the outer end of the linkage rod is rotatably connected to the lifting plate above the worm.

[0007] Preferably, a rotating block is fixedly provided on the bottom side of the lifting plate, and the outer end of the linkage rod is rotatably connected to the corresponding rotating block.

[0008] Preferably, both left and right sides of the top of the bottom plate are rotatably connected with horizontal threaded sleeves through a rotating frame, the threaded sleeve is threadedly connected with a first threaded rod through the outer end, and the inner end of the threaded sleeve is connected with a rotating mechanism for driving the threaded sleeve to rotate;

[0009] The left and right sides of the top of the bottom plate are both provided with horizontal sliding grooves, the sliding grooves are slidably connected with sliders, and the outer surface of the sliders is fixedly connected to the outer surface of the first threaded rod via a fixing frame;

[0010] The outer end of the first threaded rod is connected with a supporting claw.

[0011] Preferably, the supporting claw comprises a threaded block fixedly connected to the outer end of the first threaded rod, and the threaded block is threadedly connected to a vertical second threaded rod;

[0012] The bottom end of the second threaded rod is fixedly connected with a fixing claw.

[0013] Preferably, the rotating mechanism comprises a first bevel gear fixedly connected to the inner end of the threaded sleeve, and a second bevel gear matched with the first bevel gear is fixedly connected to the output shaft of the motor.

[0014] Preferably, movable wheels are provided at the bottom of the base plate.

[0015] Preferably, a safety guardrail is fixedly connected to the top of the lifting platform.

[0016] Beneficial Effects

[0017] The present invention provides an auxiliary lifting structure for power maintenance. Compared with the existing technology, it has the following beneficial effects:

[0018] (1) When the power maintenance auxiliary lifting structure is working, the bottom plate, mounting frame, motor, worm, rotating gear, arc rod, linkage rod and lifting plate are arranged. The motor is started to drive the worm to rotate, the worm drives the rotating gear to rotate the arc rod, and the arc rod drives the linkage rod to raise the lifting plate. Only one motor power source is needed to complete the lifting, thereby saving production costs. In addition, there are at least three arc rods and linkage rods, which can stably support the lifting plate, thereby making the device more stable, so that the staff can work on the lifting plate with confidence.

[0019] (2) The electric power maintenance auxiliary lifting structure cooperates with the threaded sleeve, the first threaded rod, the threaded block, the second threaded rod, the fixed claw, the first bevel gear, the second bevel gear, the sliding groove and the sliding block. The electric motor drives the worm to rotate and drives the second bevel gear to rotate at the same time. The rotation of the second bevel gear drives the first bevel gear to rotate the threaded sleeve. Due to the limitation of the sliding groove, the rotation of the threaded sleeve causes the first threaded rod to extend. The first threaded rod drives the threaded block to extend the second threaded rod. The second threaded rod is rotated to fix the fixed claw to the ground, thereby increasing the stability of the device, thereby reducing the shaking feeling of the staff on the lifting plate, and at the same time increasing the work safety of the staff.
