Description

Technical Field

[0001] The utility model specifically relates to a three-dimensional protective device for electric power construction operations, belonging to the technical field of electric power construction operations. Background Art

[0002] In the power system, it is necessary to set up line cables or to repair the power engineering lines at high places. When the staff engaged in substation maintenance perform maintenance on the power facilities, they must climb to a height to carry out their work, so a lifting machine is used to perform three-dimensional power construction. A construction platform is fixed on the lifting machine, and a certain height is lifted under the action of the lifting rod to send the staff to the power maintenance position. For example, the Chinese patent publication number: CN116425094A discloses a three-dimensional power construction operation auxiliary device, whose structure includes a controller, a moving wheel, a hydraulic lifting frame, an operating device and a frame. The device When the device is in use, the worker stands on the construction platform, and the protection frame and door panel surround the construction platform in a fenced state. The two can cooperate with each other to protect the construction platform, effectively ensuring the work safety of the workers; however, the construction platform of this structure can only be set outside the pole, and the operator cannot approach the maintenance part of the pole. Moreover, when laying or replacing the cable, it is affected by the gravity of the cable itself. During the process of fixing the cable to the installation position, it is easy for the cable to slip to the ground and need to be re-pulled. In addition, when the existing construction platform is lifted to a high position, the platform is prone to shaking in windy weather. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes a three-dimensional power construction operation protection device, which can improve the wind resistance. At the same time, it can facilitate the construction of power facilities in the space around the utility poles, and can assist in pulling the cables and temporarily locking the cable position.

[0004] The utility model of the three-dimensional protection device for electric power construction comprises:

[0005] A pedestal, the pedestal being fixed to the lifting end of the hydraulic lift; a slideway with a hollow end is provided in the middle of the pedestal;

[0006] The fence includes a fixed fence and a movable fence, one side of the fixed fence is hollow, and the fixed fence is fixed to the edge of the pedestal; the movable fence is hinged to the hollow side of the fixed fence; the pedestal is fixed with a limit rail at the hollow end of the fixed fence; the movable fence is movably connected with the limit rail;

[0007] An anti-fall hanging unit, the anti-fall hanging unit comprises an anti-fall rod and a safety rope, the anti-fall rod is fixed to the top surface of the fixed fence through a column, and the two ends of the anti-fall rod are fixed with limit columns; one end of the safety rope is slidably installed with the anti-fall rod through a C-shaped sliding buckle; the other end of the safety rope is fixed with a buckle; the buckle is hung with the anti-fall safety belt;

[0008] A cable pulling assembly is arranged on both sides of a fixed fence, and the cable pulling assembly includes a seat plate fixed to the fixed fence, a wire drum unit and a one-way wire biting unit are fixed on the outer side of the seat plate, a rocker is fixed to the rotating end of the wire drum unit, and a plurality of wire clamps are fixed to the wire end of the wire drum unit; the one-way wire biting unit includes two clamping blocks slidably arranged on the seat plate, and a limiting spring is installed at one end of the two clamping blocks away from each other; a one-way ratchet unit is fixed to the inner surface of the clamping block, and a clamping wheel is rotatably arranged on the outside of the clamping block; the rod body of the clamping wheel is fixed to the rotating end of the one-way ratchet unit.

[0009] During power construction, the movable fence is rotated and flipped up along the hinged position so that the movable fence is pressed against the limit rail on one side. At this time, the slide of the pedestal can be fully exposed. At this time, the slide of the pedestal can be flexibly engaged with the outside of the electric pole, or after rising to the construction position, the slide can be flexibly engaged with the electric pole; then, the movable fence is reset so that the movable fence is flexibly engaged with another limit rail; during the lifting process of the hydraulic lift, the staff needs to wear a fall-proof safety belt and flexibly engage the fall-proof safety belt with the buckle of the safety rope. When the staff needs to walk on the pedestal, they slide along the anti-fall rod through the slide buckle. At the same time, the bottom of the slide buckle is hollow and can pass through the column smoothly;

[0010] When the cable needs to be pulled, the wire clamp is separated from the fixed fence, and the wire drum unit is driven by the rocker to unwind and lower the wire. When the wire clamp reaches the ground, the wire clamp and the cable are clamped. Then, the wire drum unit is driven by the rocker to reel it in. At this time, the cable is pulled to the fixed fence position. Then, the clamp block is pulled outward to compress the limit spring, and the cable is clamped between the two clamping wheels. The cable can be bitten and clamped by the limit spring. At this time, the wire clamp is pressed to separate the wire clamp from the cable; then, the cable is pulled to the installation position. During traction, the two clamping wheels rotate unidirectionally. When the cable is separated from the installation position, since the unidirectional ratchet unit rotates unidirectionally, the two clamping wheels do not rotate at this time, and the cable is directly clamped; after the cable is installed at the installation position, the clamp block is pulled outward to compress the limit spring to separate the cable from the two clamping wheels.

[0011] Furthermore, it also includes a position-adjusting ladder unit, which includes a slide column fixed on both sides of the slide; a slide table is slidably provided on the slide column, and a ladder is hinged on the slide table; a locking block is movably engaged with the bottom surface of the slide table; a slide rail is fixed on the inner side of the slide, and a protective tooth plate is slidably provided on the slide rail; the protective tooth plate is movably engaged with the end of the slide; a first rocker is rotatably provided on the locking block, and a locking gear device elastically locked with the protective tooth plate is provided at one end of the locking block away from the slide table; a second rocker that is clamped with the protective tooth plate is screwed on the base;

[0012] When the pedestal rises to the construction position, the protective tooth plate is pushed to abut the electric pole, and then the second rocker is rotated to lock the pedestal and the protective tooth plate through the second rocker. When it is necessary to climb to the high position of the electric pole for construction, the ladder is swung and pressed against the electric pole. Then, it is unlocked by the lock gear and the slide is slid along the slide column to make the slide slide to the predetermined position, and it is locked again by the lock gear. Then, the slide position is locked by the first rocker. At this time, the slide position limit is completed. At this time, the slide, ladder and electric pole form a triangular support structure, which is convenient for workers to climb the ladder and enter the construction position for construction; when it is necessary to construct power facilities at the extension part of the electric pole, the ladder is swung so that the ladder is overlapped with the fixed fence. Then, according to the above steps, the ladder position is adjusted. At this time, a triangular support structure is formed by the fixed fence, ladder and slide. At this time, the workers climb and step on the ladder to enter the construction position for construction.

[0013] Furthermore, the tooth lock includes a support fixed on a base, a handle is slidably provided on the support, and a locking tooth block is fixed on the bottom surface of the handle; a locking spring is provided between the locking tooth block and the support; in a natural state, the locking spring presses the locking tooth block toward the protective tooth plate, thereby locking the protective tooth plate and the locking block. When unlocking is required, the handle is lifted to compress the locking spring. At this time, the locking tooth block and the protective tooth plate are separated, thereby unlocking the protective tooth plate and the locking block.

[0014] Furthermore, the fixed fence is fixed with sliding cylinders on both sides near one hollow end, and a Y-shaped windproof locking rod is slidably arranged on the inner side of the sliding cylinder, and a bolt body which is locked with the windproof locking rod is screwed on the sliding cylinder; the two windproof locking rods are staggered up and down; when raised to the construction position, the windproof locking rod is slid along the sliding cylinder, and the inner surfaces of the two windproof locking rods are respectively clamped and limited to the outer surface of the electric pole, and then the position of the windproof locking rod is locked by the bolt body, at this time, the windproof locking rod is limited to the electric pole, thereby increasing the installation stability of the pedestal and the fence, and improving the wind resistance of the pedestal and the fence.

[0015] Furthermore, a tooth groove is provided on the top surface of the windproof locking rod; through the cooperation between the tooth groove and the bolt body, the windproof locking rod can be stably locked.

[0016] Furthermore, a plurality of anti-skid grooves are spaced apart on the outside of the clamping wheel, and the anti-skid grooves of the two clamping wheels are staggered. When the clamping wheels clamp the cable, the anti-skid groove of one clamping wheel is pressed onto the surface of the cable, and the surface of the non-anti-skid groove of the other clamping wheel is pressed onto the cable, thereby achieving three-point clamping of the cable and ensuring a tight bite of the cable.

[0017] Furthermore, the top surface of the pedestal is a mesh structure, which can reduce the deadweight of the pedestal.

[0018] Compared with the prior art, the three-dimensional protective device for electric power construction of the utility model has a pedestal that can be clamped with the electric pole and movable limited, which can not only realize the wind resistance of the pedestal and ensure that the pedestal provides a stable construction platform during the construction process, but also facilitate the construction of power facilities in the space around the electric pole. For the extreme position, an expansion platform with triangular support can be provided by adjusting the ladder unit, and the ladder unit can provide a suitable temporary construction height according to needs, without the need for frequent hydraulic lifts to find a suitable construction position; when the cable is pulled, the cable traction is realized by the cable traction assembly, and the cable is unidirectionally pulled and laid out to prevent the cable from falling to the ground during the construction process.
