Description

Screw lifting device

technical field

The utility model relates to the technical field of electric construction lifting tools.

Background technique

In the field of electric power construction, it often involves high-altitude operations. The tools and materials needed for such high-altitude operations need to be carried or pulled up with construction transfer ropes. It is very inconvenient to carry, which makes climbing difficult and makes construction operations uncomfortable. Convenience reduces work efficiency and increases danger. If the pulley is used to pull the construction rope, the tool or material hanging on one end of the construction rope will shake too much, which will easily cause decoupling accidents, and the tool will rise to the working position. At the height of the personnel, because the operators are working, it is difficult to grasp the tools or materials with a relatively large degree of shaking. There is no remaining space to pull the construction rope, and there is often no suitable position for hanging or binding the construction rope at high places.

For above-mentioned needs a kind of lifting device that can transport simple small tool or material to high place now.

After being lifted in place, the manual wheel at the bottom can be fixed, and the lifting ring can be stabilized on the side of the operator, so that the operator can pick up and hang the tools at any time.

In order to solve the above problems, the technical solution adopted by the utility model is to provide a screw lifting device, which is characterized in that: it includes a vertically arranged screw and a screw nut on the screw, and the sliding screws on both sides of the screw nut and the screw. The bottom end of the slide rod is fixed on the base plate, the lower end of the lead screw is hinged with the base plate through the lower bearing, the screw nut is connected with a hook that can move up and down with the lead screw nut, and the lead screw is The manual wheel connected with the sheave on the lead screw body through a belt rotates.

Preferably, the top ends of the two slide bars are connected by a cross bar, the top end of the lead screw is hinged to the upper bearing at the lower part of the cross bar, and a vertical through hole is provided on the lead screw nut, and the lead screw nut Sliding fit with a slide rod passing through the through hole.

Preferably, a lift ring fixedly connected with the lead screw nut is provided around the lead screw nut, and the hook is arranged on the lift ring.

Preferably, the manual wheel is arranged horizontally, the manual wheel is hinged to the base plate through a rotating shaft, and a rocker is provided on the manual wheel.

The beneficial effect of adopting the above technical solution is that the hook of the lifting device can carry multiple tools, and the lifting stability is good, and it can accurately stop at the position of the operator at a high place without shaking. Fix the manual wheel at the bottom, stabilize the lifting ring on the side of the operator, and the operator can pick up and hang the tools at any time.
