Description

Technical Field

[0001] This utility model belongs to the technical field of power maintenance devices, specifically relating to a maintenance device suitable for power maintenance. Background Technology

[0002] Currently, the maintenance and repair of power equipment inevitably involves power equipment installed at high positions. When maintaining and repairing such equipment, such as applying anti-corrosion paint and adding lubricating oil, the height limitation can create obstacles for the workers. Therefore, it is necessary to use retractable power maintenance and repair devices when maintaining and repairing such power equipment. However, current power maintenance and repair devices are generally manually operated to avoid climbing, which is not conducive to the operation of workers.

[0003] A prior art patent, CN110459977A, discloses a live-line inspection and maintenance device for power equipment. This device includes a telescopic rod and a clamping mechanism. The clamping mechanism includes a base plate, a worm gear, a worm, and a linkage mechanism. The mobility of the linkage mechanism serves to clamp the device. The worm gear and worm drive the linkage mechanism. The base plate is located on both sides of the clamping mechanism to install and protect the worm gear and worm device. However, in actual operation, this live-line inspection and maintenance device requires adjustment of the clamping part before the corresponding inspection and maintenance operations can be performed. This results in low automation and low work efficiency. Utility Model Content

[0004] The technical problem solved by this utility model is to overcome the defects existing in the prior art and provide a maintenance device suitable for power maintenance.

[0005] The technical solution adopted in this utility model is as follows:

[0006] The present invention discloses a maintenance device suitable for power maintenance, comprising a telescopic mechanism and a clamping mechanism connected together, the telescopic mechanism and the clamping mechanism being connected by a threaded mechanism; the telescopic mechanism includes a telescopic rod I and a telescopic rod II, the telescopic rod II being disposed inside the telescopic rod I; the clamping mechanism is an axisymmetric structure, including a limiting rod, a linkage rod, a clamping arm, a connecting block and a fixing block, one end of the clamping arm being connected to a clamping claw, one end of the linkage rod being movably connected to the clamping arm, and the other end being movably connected to the connecting block, the linkage rod including parallel linkage rod I and linkage rod II, one end of the limiting rod being movably connected to linkage rod II, and the other end being movably connected to the fixing block.

[0007] The telescopic boom I is equipped with a motor, a transmission mechanism I, and a transmission mechanism II. The motor is connected to the transmission mechanism I via a transmission shaft I, and the transmission mechanism I is connected to the transmission mechanism II via a transmission track.

[0008] The telescopic rod II has a matching gear and rack inside. The gear is connected to the transmission mechanism II through the transmission shaft II, and the rack is located on the inner wall of the telescopic rod II.

[0009] The telescopic rod II has symmetrical slots, and the drive shaft II passes through the inside of the slots.

[0010] The clamping mechanism also includes a hydraulic device, which includes a hydraulic rod connected to the connecting block.

[0011] The telescopic rod I is equipped with a motor control button and a hydraulic control button. The motor control button is electrically connected to the motor, and the hydraulic control button is electrically connected to the hydraulic device.

[0012] The limiting rod has a through groove I in the middle, and the clamping arm has a through groove II in the middle. The linkage rod passes through the interior of through groove I and through groove II.

[0013] The inner side of the gripper is equipped with an insulating and anti-slip layer.

[0014] This utility model has the following beneficial effects:

[0015] 1. The cooperation between the telescopic mechanism and the clamping mechanism reduces the difficulty of operation when maintaining and repairing power equipment installed at high positions, while ensuring the personal safety of the operators.

[0016] 2. The practical combination of motors and motor control buttons, along with hydraulic devices and hydraulic control buttons, enables semi-automated operation of power equipment maintenance and repair, enhancing convenience and improving work efficiency.

[0017] 3. The combined action of drive shaft I, drive shaft II, transmission mechanism I, transmission mechanism II, transmission track, gears and racks enables the automatic extension and retraction of the telescopic mechanism, improves the automation level of the telescopic mechanism, facilitates operation by operators, and saves labor costs.

[0018] 4. The hydraulic rod, connecting block and several connecting rods work together to realize the automatic clamping or releasing operation of the clamping mechanism, which improves the automation level of the clamping mechanism and avoids the problem of repeated manual debugging during maintenance and repair, thus effectively improving work efficiency.

[0019] 5. The insulating and anti-slip layer ensures that the clamped parts are firmly held in place, preventing them from falling off. It also allows for live operation of electrical equipment during maintenance and repair, ensuring the safety of workers and overcoming the problem of repeated power outages and restorations during maintenance.

[0028] like Figures 1 to 7 As shown, the present invention provides a maintenance device suitable for power maintenance, comprising a telescopic mechanism and a clamping mechanism connected together, which are connected by a threaded mechanism; the telescopic mechanism includes a telescopic rod I1 and a telescopic rod II2, with the telescopic rod II2 located inside the telescopic rod I1; the clamping mechanism is an axisymmetric structure, including a limiting rod 3, a linkage rod, a clamping arm 6, a connecting block 18, and a fixing block 24; one end of the clamping arm 6 is connected to a clamping claw 7; one end of the linkage rod is movably connected to the clamping arm 6, and the other end is movably connected to the connecting block 18; the linkage rod includes parallel linkage rods I4 and II5; one end of the limiting rod 3 is movably connected to the linkage rod II5, and the other end is movably connected to the fixing block 24.

[0029] The telescopic rod I1 is equipped with a motor 8, a transmission mechanism I 9 and a transmission mechanism II 10. The motor 8 is connected to the transmission mechanism I 9 through a transmission shaft I 11, and the transmission mechanism I 9 is connected to the transmission mechanism II 10 through a transmission track 12.

[0030] The telescopic rod II 2 has a matching gear 13 and rack 14 inside. The gear 13 is connected to the transmission mechanism II 10 through the transmission shaft II 15, and the rack 14 is located on the inner wall of the telescopic rod II 2.

[0031] The telescopic rod II 2 is provided with a symmetrical strip groove 16, and the drive shaft II 15 passes through the inside of the strip groove 16.

[0032] The clamping mechanism also includes a hydraulic device 17, which includes a hydraulic rod 19 connected to a connecting block 18.

[0033] The telescopic rod I1 is equipped with a motor control button 22 and a hydraulic control button 23. The motor control button 22 is electrically connected to the motor 8, and the hydraulic control button 23 is electrically connected to the hydraulic device 17.

[0034] The limiting rod 3 has a through groove I 20 in the middle, and the clamping arm 6 has a through groove II 21 in the middle. The linkage rod passes through the interior of the through groove I 20 and the through groove II 21.

[0035] The inner side of the gripper 7 is provided with an insulating and anti-slip layer.

[0036] Specifically, the telescopic mechanism is the handheld part of the operator. The operator can control the forward and reverse rotation of the motor 8 through the motor control button 22, thereby realizing the relative displacement between the telescopic rod I1 and the telescopic rod II 2, and thus realizing the extension and retraction of the telescopic mechanism.

[0037] Specifically, when the motor control button 22 is pressed, the motor 8 starts and drives the transmission mechanism I9 to rotate via the transmission shaft I11. The transmission mechanism I9 drives the transmission mechanism II 10 to rotate via the transmission track 12. The transmission mechanism II 10 drives the gear 13 to rotate via the transmission shaft II 15. The gear 13 drives the rack 14 to move. The rack 14 is located on the inner wall of the telescopic rod II 2. The two are integrated. The rack 14 drives the telescopic rod II 2 to move.

[0038] Specifically, the telescopic rod II 2 is provided with a symmetrical strip groove 16, and the drive shaft II 15 passes through the inside of the strip groove 16, so that the drive shaft II 15 will not obstruct the telescopic rod II 2's extension and retraction.

[0039] Specifically, pressing the hydraulic control button 23 controls the hydraulic rod 19 to move. When the hydraulic control button 23 controls the hydraulic rod 19 to retract into the hydraulic device 17, the connecting block 18 drives the linkage rod I 4 and linkage rod II 5 to move, which in turn drives the clamping arm 6 to move to achieve the clamping operation. Conversely, when the hydraulic control button 23 controls the hydraulic rod 19 to push out of the hydraulic device 17, the releasing operation is achieved.
