Semi-suspension type single-beam crane

Abstract

The invention belongs to the technical field of hoisting equipment, and particularly relates to a semi-suspension type single-beam crane which comprises a base, a stand column, a walking track, an electric travelling crane and an electric hoist. The stand column is vertically fixed to the top face of the base, the walking track is installed on the stand column in an overhanging mode, the electric travelling crane is movably installed on the walking track, the electric hoist is fixed to the bottom of the electric travelling crane, and limiting damping assemblies are installed on the front side face and the rear side face of the electric travelling crane correspondingly. An auxiliary walking structure is further mounted on the electric travelling crane, and the auxiliary walking structure comprises a mounting plate and a connecting frame. According to the semi-suspension type single-beam crane, through the configured auxiliary walking structure, it is guaranteed that the electric travelling crane is more stable during moving, moving friction is reduced, and the service life of equipment is prolonged; by arranging the limiting damping assemblies, the safety of the electric travelling crane is guaranteed, and the situation that the electric travelling crane collides with the walking track in the moving process and is damaged is avoided.

Description

technical field [0001] The invention belongs to the technical field of hoisting equipment, and in particular relates to a semi-suspended single-girder crane. Background technique [0002] A crane refers to a multi-action hoisting machine that vertically lifts and horizontally transports heavy objects within a certain range, also known as a crane, aeronautical crane, and crane; a single-girder suspension crane is used to suspend and fix the beam on the building's walking track (I-beam) For the crane on the crane, the setting position and span of the walking track can be set freely. It is most suitable for the production line and other places, and the crane can run freely under the elevated single girder. [0003] In the original semi-suspended single-girder crane, the electric hoist moves directly on the walking track, which is difficult to ensure the smooth movement, especially in the case of lifting different heavy objects, it is easy to cause the electric hoist to shake an...

Problems solved by technology

[0003] In the original semi-suspended single-girder crane, the electric hoist moves directly on the walking track, which is difficult to ensure the smooth movement, especially in the case of lifting different heavy objects, it is easy to cause the electric hoist to shake and cause different degrees of wear, which affects the crane. service life
