Description

An electric hoist suspension system

technical field

The utility model relates to the technical field of cranes, in particular to an electric hoist suspension system.

Background technique

Electric hoist is a relatively light lifting equipment, which is installed on the crane and gantry crane. Electric hoist has the characteristics of small size, light weight, simple operation and convenient use. It is used in industrial and mining enterprises, storage terminals and other places. In the prior art, the electric hoist suspension system usually includes a stand, a crossbeam and an electric hoist. The crossbeam is fixed on the stand. The slide rail of the beam moves back and forth and carries heavy objects. However, in the prior art, the stand and the crossbeam of the electric hoist suspension system are fixed, and the crossbeam cannot move at the upper end of the stand, which limits the lifting range of the electric hoist; moreover, the two ends of the crossbeam are usually not set Limiting device, the electric hoist is easy to hit the stand at the end of the beam during the back and forth movement.

Utility model content

The technical problem to be solved by the utility model is to provide an electric hoist suspension system which has a large lifting range and can limit the maximum moving distance of the electric hoist, aiming at the deficiencies of the above-mentioned prior art.

In order to solve the above technical problems, the technical solution of the present invention is: an electric hoist suspension system, including a stand, a beam, an electric hoist and a control device; At the upper end of the stand; the lower end of the beam has a slide rail, and the electric hoist can move back and forth along the slide rail, and a limit device is respectively arranged at both ends of the slide rail to limit the maximum moving distance of the electric hoist; The control device is electrically connected with the electric hoist to control whether the electric hoist works or not.

As a further elaboration of the utility model:

The limit device includes a limit baffle and a contact sensor on one side of the limit baffle, the contact sensor is electrically connected to the control device, and when the contact sensor touches the electric hoist, it immediately feeds back a contact signal to the control device, After the control device receives the contact signal, it controls the electric hoist to stop moving immediately.

The electric hoist includes a body on which an electric trolley, a reel, a steel cable, a hook device, a lifting motor and a reducer are installed; the lifting motor, the reel and the reducer are connected in sequence, and the steel cable is set On the reel, the hook device is connected to the steel cable, and the lifting motor drives the reel to rotate through the reducer, and then pulls the hook device on the steel cable to lift heavy objects; the electric trolley is equipped with two The set of wheels includes a set of driving wheels and a set of driven wheels. The driving wheels and driven wheels can roll back and forth on the slide rail of the crossbeam.

The beneficial effects of the utility model are: since one end of the beam of the utility model is rotatably installed on the upper end of the stand, the hoisting range of the electric hoist suspension system is changed from a straight line range to a range with the beam as the radius and the stand as the center. Round, which greatly improves the lifting range and lifting efficiency; because a limit device is installed at both ends of the slide rail to limit the maximum moving distance of the electric hoist, thus avoiding the problem that the electric hoist hits the stand at the end of the beam .
