There is a chute extending along the length direction of the straight side, and the two sides of the support ring are provided with sliders that can be stuck in the chute in the two straight sides of the n-type. The hydraulic lifting device for the electric cover also includes: Suspension beam, the suspension beam can pass through two support rings, a suspension rope is also arranged on the suspension beam, a suspension hook is provided at the lower end of the suspension rope, and casters are provided at the bottom of the support base.

The hydraulic lifting device for the electric power cover of the utility model is provided with a group of n-shaped brackets, and the brackets are set on the base, and then a hydraulic jack is set on the base, and a support ring is set at the end of the piston rod of the jack. Sliders are set on both sides of the ring, so that the support ring can be accurately positioned and run in the N-shaped bracket and load-bearing. Using the casters installed on the base, the two lifting brackets can be moved conveniently, which can greatly reduce labor intensity. When using The two support frames can be easily pushed to or from the desired position. When lifting is required, push the support frames to the two sides of the power cover with hoisting holes, and then use the hook hanging on the suspension beam to hook on the power cover. on the board, and then start the hydraulic jack to realize the lifting of the electric cover. After lifting, push the support frame away from the electric cover and perform corresponding operations. Return of the cover.

The movable detachable connection between the support ring and the piston rod is either a plug-in connection or a threaded connection.

The casters on the bottom of the support base are composed of two directional wheels and two universal wheels.

The directional wheels are set as front wheels, and the universal wheels are set as rear wheels.

With this arrangement, it has the advantages of stable straight-line walking test, good turning control, and good gravity balance.

The hanging beam is composed of several sections, and the sections are connected by threads.

The hanging beam is composed of several sections, which can be conveniently stored and transported.

Positioning holes and latches are provided at both ends of the suspension beam.

When the hanging beam passes through the support ring and is supported on the support ring, the two ends are locked with pins through the positioning holes, which can prevent the lifting beam from slipping from the support ring during the movement of the two lifting brackets during operation and damage the electric cover Or hit the staff.

The sliders on both sides of the support ring are rollers or rolling bearings.

A cart-type handle is arranged on the support base.

The purpose of setting the trolley handle is to facilitate the movement of the lifting bracket.

The sling is a sling. The suspension chain is suspended on the suspension beam through suspension rings.

The support base is a square frame welded by hollow channel steel, and a steel plate is set on the square frame as a support surface.

The support base adopting this structure has the advantages of light weight, portability and good structural support performance.

In summary, the utility model has the following advantages compared with the prior art:

The hydraulic lifting device of the electric power cover of the utility model, 1. Solve the problem that construction personnel only rely on simple tools such as steel shovels and crowbars to manually pry, excavate, lift, and drag and drop a large number of heavy cable cover plates, which requires high labor intensity and difficult work. A state of inefficiency.

2. Avoid personal injury to construction workers during the opening or reset of the electric cover, and improve construction safety.

3. Reduce the opening or reset time of the power cover, saving time for power cable construction or emergency repair of cable accidents, and improving economic benefits.

4. Avoid damage to the power cover during opening or resetting, save the cost of maintenance and replacement of the power cover, ensure the safe operating environment of the power cable, and improve the reliability of power supply.
