Silent single-beam European style crane

Abstract

The invention discloses a silent single-beam European style crane. The crane comprises a cross beam, wherein a mounting frame is movably arranged at the bottom of the cross beam; a telescopic outer rod is movably arranged on the mounting frame; a telescopic inner rod is movably arranged at the inner side of the telescopic outer rod; two auxiliary connecting arms are arranged below a main connecting arm; and two electromagnetic chucks are fixedly arranged at the bottom of the auxiliary connecting arms. By arranging a first electromagnet, a first coil winding, a second electromagnet and a second coil winding, a movable rack is kept stable in the running process, a first pulley and a second pulley are prevented from colliding with a track, and noise is avoided; the movable rack and the track are wrapped through the cross beam, sound is effectively isolated, and the sound is absorbed through a sponge plate in the cross beam, so that the silence performance of the crane is greatly improved; the telescopic outer rod and the telescopic inner rod are high in stability in the carrying process, the possibility of collision is avoided, and sound is prevented; and the crane can meet the carrying requirements of objects at different positions and is wide in applicability.

Description

technical field [0001] The invention relates to a crane, in particular to a silent single-girder European-style crane. Background technique [0002] Single girder crane is a kind of common lifting machinery, including beam frame, cart, trolley, electric hoist and control mechanism and other parts: the beam frame is composed of end beams on both sides and the main beam connecting the end beams, and the end beam is composed of carts The drive runs on the end beam track, and the electric hoist runs on the main beam track with the trolley, thereby lifting the workpiece at the corresponding position through the hook; the traditional single-girder European-style crane is under heavy pressure when it is working, and collisions between the pulley and the track are prone to occur And misalignment, easy to generate noise, poor mute ability, traditional single-girder European-style cranes are lifted by ropes, prone to bumps, resulting in noise, poor safety, and traditional single-girde...

AI Technical Summary

Problems solved by technology

[0004] The following problems are solved: the traditional single-girder European-style crane is under heavy pressure, and the pulley and the track are prone to collision and misalignment, which is easy to generate noise and has poor mute ability; the traditional single-girder European-style crane is lifted by rope, which is prone to bumping Noisy, poor safety; the traditional single-girder European-style crane has only one hook, which cannot lift multiple items, and has poor applicability
