Abstract

The utility model relates to a lifting device for live-wire operation. The lifting device comprises a lifting rod which is driven by a hydraulic device, and a working platform which is arranged on the top of the lifting rod. The lifting device can be arranged at any place below cables, so that the live-wire operation performed by an operator in a mode of climbing electric poles can be eliminated; and the lifting rod is only driven by a hydraulic driver of the hydraulic device, so that the lifting device is quite convenient to mount and dismount.

Description

Lifting device for live working

technical field

The utility model relates to a lifting device for live work.

Background technique

In the fields of electric power and communication, most of them use electric poles to carry high-voltage cables, communication transmission optical cables and other power supply equipment. When the cables or optical cables or power supply equipment on the poles are erected or installed or when there is a breakdown or the trees are close to the cables or optical cables, mechanical equipment and manual climbing are usually used to climb to the poles or trees to perform inspections on the cables or optical cables or power supply equipment. erection or repair. The mechanical equipment is composed of a motor vehicle and a liftable insulation bucket installed on the motor vehicle. For the section where there is a house or no car under the pole, when repairing cables or optical cables or power supply equipment, it cannot be used The mechanical equipment is placed in a designated place, so in some mountainous areas, when repairing cables or optical cables or power supply equipment, it is usually done by manual electrification. When working with live electricity, people use foot buckles to climb electric poles or trees. The foot buckles include two and one end is fixed to form a clamping arm that is approximately circular. The clamping arm is provided with a saw-shaped Teeth, and there is a pedal at the fixed part of the two clamping arms. The first problem reflected by the foot buckle of this structure is that the distance between the two clamping arms cannot be adjusted at will, because the thickness of the pole and the tree is different. , climbers rely on the angle of inclination between the clamp arm and the pole to climb, and if this angle is not well grasped, it is prone to tripping, so it is not safe to use this kind of foot buckle; secondly, the saw-shaped teeth set on the clamp arm It is only suitable for climbing wooden poles, not for climbing rigid poles such as cement; in addition, whether the distance between the two clamping arms and the diameter of the required climbing pole is suitable is a major factor determining the speed, while climbing The climbing speed directly affects the efficiency of cable installation or troubleshooting, and the inability to adjust the distance between the clamp arms of the foot buckle will affect the climbing speed.

Contents of the invention

The purpose of this utility model is to provide a lifting device for live working which solves the above problems in a way that can be easily installed and disassembled.

The lifting device for live work proposed by the utility model includes a lifting rod driven by a hydraulic device and a working platform installed on the top of the lifting rod.

The upper area of the lifting pole is also equipped with a positioning assembly connected with the electric pole. The positioning assembly has an insulating telescopic slideway that is connected with a rolling bearing arranged on the elevating rod at one end.

The working platform is composed of insulating buckets.

The lifting device for live work proposed by the utility model adopts a lifting rod and a working platform installed on the top of the lifting rod, so the device can be installed anywhere under the cable, so as to avoid the operator from using the climbing pole At the same time, the lifting rod is only driven by the hydraulic drive, which is very convenient for installation and disassembly; in addition, the positioning component can make the lifting rod and the electric pole fixed by connecting, so as to ensure that the constructor safety.

Description of drawings:

Accompanying drawing 1 is the appearance structure diagram of an embodiment of the lifting device for live work proposed by the utility model.

Detailed ways:

Referring to Fig. 1, this figure shows the overall structure of the appearance of an embodiment of the lifting device for live working proposed by the utility model. The device includes a hydraulic driver 1 and a lifting rod 2, as well as a working table 3 installed on the top of the lifting rod 2. The hydraulic driver 1 wherein can be fixed on the ground surface by a rope 11 or other similar parts, and a control box 12 is installed on the top of the hydraulic driver 1, and the control box 12 is used to control the lifting action of the elevating rod 2. Lifting rod 2 has a plurality of mutually nested rods, and a workbench 3 is installed on the top of the top elevating rod. This workbench 3 is similar to an insulating bucket, and the operator performs construction work in the workbench 3 . The upper area of the elevating mast 2 is also equipped with a positioning assembly 4 connected to the electric pole 5 . The positioning assembly 4 has a rolling bearing 41 and a telescopic slideway 42 installed on the uppermost pole member 21 of the lifting rod 2 . One end of the telescopic slideway 42 is sleeved on the rolling bearing 41 , and the other end can be connected with the pole 5 . The telescopic slideway 42 can be made of rods or plates nested in each other. The function of the telescopic slideway 42 is to solve the problem that when the distance between the lifting device and the pole 5 is far or close, the two can be stretched in a telescopic manner. can connect to each other.
