Description

Technical Field

[0001] The invention belongs to the technical field of electric power equipment installation, and in particular relates to an installation device for an insulating sheath insulating rod of a power distribution line. Background Art

[0002] With the rapid development of my country's distribution network, the construction process of distribution network projects has become more standardized, scientific and technical, and the equipment used has become more advanced. With the continuous development of power technology and the increasing social demand for power supply safety and stability, safe operation is becoming more and more important to power companies. Live working is a method of operation for maintenance and testing of high-voltage electrical equipment without power outage. Electrical equipment needs to be tested, inspected and repaired frequently during long-term operation. Live working is an effective measure to avoid power outages for maintenance and ensure normal power supply. Live working has been developed for many years. During the operation, it will bring inconvenience and losses to residents and businesses, and also bring a heavy workload to operators. During this period, more serious live working accidents have occurred, causing irreparable loss of life and property. From the lessons of the accident, it is deeply realized that most of the accidents in the construction of distribution lines are caused by mistakes made by personnel during the operation. Relying solely on the requirements of safety technical regulations cannot fundamentally prevent the occurrence of accidents. Inventing and designing targeted special tools can improve this problem well.

[0003] In the prior art, when installing the insulating sheath of the distribution line, the workers are mainly transported to a high place for installation by an insulating boom truck, that is, the workers wear insulating safety helmets and full sets of insulating clothing to operate the insulating boom truck and the insulating bucket to approach the installation position of the sheath for operation. The front-line team reported that the existing operation method for installing the insulating sheath has the following problems: First, it is easily restricted by terrain conditions. If the pole is in complex terrain such as mountains and orchards, the insulating boom truck cannot reach the operation position and cannot carry out the operation; second, the operation cost is high, a large number of workers need to be dispatched, and an insulating boom truck is required for installation; third, the workers need to come into close contact with the live body, which poses a safety risk. The distribution lines are compact, the electrical equipment is densely arranged, and the operation range is narrow. The workers are close to the live body, which is prone to phase-to-ground short circuit or phase-to-phase short circuit. Fourth, the working efficiency of the insulating sheath is low, the operation steps are many, the procedures are complicated, and the work is time-consuming.

[0004] In order to solve the shielding problem of drop-out fuses and lightning arresters, a set of insulating rod insulating sheath installation tools is designed to improve the safety and convenience of operating operations, the firmness of the installation of the insulating sheath of the distribution line, reduce the labor intensity of operators, and improve the efficiency of non-stop operations.

It should be noted that the hand-held rod 100, the first transmission rod 205, and the rotating rod 408 are all made of insulating plastic to ensure that the staff can perform power application. The hand-held rod 100, the first transmission rod 205, and the rotating rod 408 are all made of insulating plastic; the other end of the rotating rod 408 passes through the first transmission rod 205, the transmission box 201 and one of the H-shaped brackets 406 and is connected to a driving gear 409, the driving gear 409 is connected to a driven gear 411 through an intermediate gear 410, the intermediate gear 410 is rotatably connected to one of the H-shaped brackets 406, the driven gear 411 is fixedly sleeved on the outside of the second worm 412, the two ends of the second worm 412 are respectively rotatably connected to the two H-shaped brackets 406, the fixed A second worm gear 413 is coaxially fixed on the fixed shaft 306, and the second worm 412 is meshed with the second worm gear 413; when working, the driving gear 409 can be driven to rotate by rotating the handle 407, and the driving gear 409 drives the second worm gear 413 to rotate through the intermediate gear 410, the driven gear 411, and the second worm 412, thereby driving the fixed shaft 306 to rotate, and finally changing the angle of the clamping mechanism 300 to adjust the angle of the insulating sheath clamped by the clamping plate 305; since the worm gear structure has self-locking properties, the stability of the fixed tube 301 and the entire clamping mechanism 300 can be guaranteed during operation.

[0035] In order to reduce the self-locking load of the second worm 412 and the second worm wheel 413, the present invention designs a locking assembly, which is arranged on the fixed shaft 306. The locking assembly includes an annular member 414 coaxially fixed on the fixed shaft 306, and the circumferential side walls of the annular member 414 are evenly distributed with card slots 415. A card block 416 is fixed to the end of the driving gear 409 away from the rotating rod 408, and a spring 417 is sleeved on the outer side of the end of the rotating rod 408 close to the driving gear 409. One end of the spring 417 is against the driving gear 409, and the other end of the spring 417 is against one of the H-shaped brackets 406. The elastic force of the spring 417 is used to push the card block 416 into the card slot 415. It is worth mentioning that the front end of the card block 416 is set to a pointed head, which is more conducive to inserting into the card slot 415 during actual operation.

[0036] When the present invention is used, the crank 202 is first turned to drive the first bevel gear 203 and the second bevel gear 204 to rotate. The second bevel gear 204 drives the third bevel gear 206, the face gear 307, and the fourth bevel gear 308 to rotate through the first transmission rod 205. The fourth bevel gear 308 drives the first worm 310 and the two first worm gears 303 to rotate through the second transmission rod 309. The synchronous rotation of the two first worm gears 303 realizes the opening and closing of the two clamping rods 304 and the clamping plates 305. When the clamping plates 305 are closed, the insulating sheath can be clamped. The staff then holds the hand lever 100 to install the insulating sheath on the outside of the power device to be shielded. When the installation angle of the insulating sheath needs to be adjusted, it can be adjusted to the first position. Pull down the handle 407, drive the driving gear 409 to mesh with the intermediate gear 410 through the rotating rod 408, and then rotate the handle 407, drive the driving gear 409, the intermediate gear 410, the driven gear 411, and the second worm 412 to drive the second worm gear 413 to rotate through the rotating rod 408, so as to adjust the angle of the clamping mechanism 300. When the angle is adjusted to a suitable position, release the handle 407 and rotate it back and forth slightly. When the block 416 and the slot 415 are aligned, the spring 417 will push the block 416 to be inserted into the slot 415, so as to lock the fixed shaft 306 and the entire clamping mechanism 300, and prevent the insulating sheath from changing its angle during the installation operation.
