Description

A high-pressure aerial work elevator

technical field

The invention relates to an elevator, in particular to an elevator used for high-altitude operations on high-voltage lines in power systems. the

Background technique

In the field of electric power transmission industry, high-altitude operation on high-voltage lines is a common job. The vertical distance from the ground is getting higher and higher. In the past, the general throwing height was 25 meters, and the modern UHV line can reach a height of 50 meters to 60 meters. On the high-altitude lines, it is necessary to repair and replace small spacers, A, B, and C phases. When installing spacer rods and other devices, the staff generally use the traditional soft ladder to go up and down. The soft ladder is easily affected by the windy weather at high altitude, so that the staff cannot move up and down effectively, and their personal safety is threatened. the

Contents of the invention

The object of the present invention is to provide a high-pressure high-altitude work elevator with simple structure, convenient operation and economical application.

The technical scheme adopted in the present invention is:

A high-pressure high-altitude operation lift, characterized in that it includes a pulley, a hand rocker arm and a main frame, a connecting rope is wound on the pulley, a hook is provided at one end of the connecting rope, the main frame includes a support rod, and a pulley splint is fixed at one end of the support rod , the pulley splint includes a left splint and a right splint, the left splint and the right splint are provided with symmetrical central holes, and the pulley and the pulley splint are clamped by a hand rocker arm.

The lift also includes positioning pins. the

A plurality of pin holes are arranged around the center hole of the right splint. the

The right side of the pulley is provided with a plurality of positioning pin grooves, and the positioning pins pass through the pin holes and fall into the positioning pin grooves. the

The upper end of the support rod is also provided with a safety belt socket. the

The center of the pedal is provided with a rope hole, and the connecting rope passes through the rope hole of the pedal. the

The main frame is made of aluminum alloy. the

The pin hole is matched with the positioning pin groove. the

The invention uses a hook to hang the elevator on the high-voltage line that needs to be operated, and wraps the pulley around the connecting rope connected to the hook. The worker stands on the pedal, and at the same time, the safety belt is fastened to the elevator through the sleeve. , the manual mechanically shakes the rocker arm, and uses the principle of the pulley to move up and down. Further, it prevents the pulley from detaching from the connecting rope, and uses the positioning pin for a more stable fixed connection. The structure is simple, easy to operate, economical and applicable, and saves time and effort. Reduce potential safety hazards and improve work efficiency. the

Detailed ways

As shown in Figures 1 and 2, the present invention includes a pulley 3, a rocker arm 9 and a main frame, the pulley 3 is wound with a connecting rope 2, and one end of the connecting rope is provided with a hook 1, and the main frame includes a support rod 4, a support rod 4 One end is fixed with a pulley splint. The pulley splint includes a left splint 13 and a right splint 12. The left splint 13 and the right splint 12 are provided with symmetrical central holes. 13 center holes of the left clamping plate fix the pulley 3 and the pulley clamping plate, the elevator also includes positioning pins 7, a plurality of pin holes 8 are provided around the center hole of the right clamping plate 12, and a plurality of positioning pin grooves 10 are provided on the right side of the pulley 3 , the positioning pin 7 passes through the pin hole 8 and falls into the positioning pin groove 10, the pin hole 8 matches the positioning pin groove 10, the center of the pedal 5 is provided with a rope hole 11, and the connecting rope 2 passes through the pedal 5 rope hole 11. The upper end of the support rod 4 is also provided with a safety belt socket 6, and the main frame is made of aluminum alloy. the

In this embodiment, the hook 1 can adopt a semi-closed structure or a fully closed structure, and the connecting rope 2 can adopt a high-strength nylon rope or palm rope to ensure that it can carry all the weight of the staff. weight. The main frame is made of solid aluminum alloy material, and the lower end of the main frame is provided with a pedal 5 . When the present invention is in use, the suspension hook 1 is hung on the high-voltage line that needs to be operated, and the staff steps on the pedal 5 . The operating hand rocker arm 9 drives the pulley 3 to run to control the up and down movement of the elevator. The elevator is also provided with a positioning pin 7. The positioning pin 7 passes through the pin hole 8 and falls into the positioning pin groove 10, which can fix the position of the elevator in the air. , the safety belt cover 6 is used for staff to hang personal safety belts. Connecting rope 2 is wound one turn on pulley 3, according to the selected connecting rope 2 material situation, also can be wound twice for increasing frictional force. The rotating structure of the pulley 3 adopts a flywheel structure similar to that of a bicycle, which can only rotate in one direction. When rotating to a desired position, manually tighten the positioning pin 7 screws to fix the position in the air. the

The invention is not only limited to high-altitude operation of electric power, but also applicable to high-altitude operations such as communication line maintenance and building construction. the
