Transverse moving mechanism of portal crane

Abstract

The invention provides a portal crane transverse moving mechanism which comprises a clamping box, a connecting sleeve and a support, a motor is installed on one side of the clamping box through bolts, a clamping belt is arranged on the inner side of the clamping box in a sleeving mode, a support is welded to the bottom of the support, a guide rail is welded to the bottom of the clamping box, clamping wheels are installed at the bottom of the support, and the clamping wheels are connected with the connecting sleeve. According to the transverse moving mechanism of the portal crane, external sundries can be prevented from falling into the clamping box, the sundries are prevented from affecting the support and stable movement, meanwhile, rainwater is prevented from falling into the clamping box, the clamping box is not prone to falling into the clamping box, the clamping box is not prone to falling into the clamping box, and the service life of the clamping box is prolonged. Components in the clamping box are prevented from being eroded by rainwater, it is guaranteed that the support and the clamping wheel completely move in the direction of the guide rail, the situation that the support and the clamping wheel deflect is avoided, the situation that a lead screw is bent due to foundation sinking is avoided, normal movement of the portal crane is guaranteed, and the transverse movement device is suitable for being used for transverse movement of the portal crane.

Description

technical field [0001] The invention relates to the technical field of gantry crane traverse equipment, in particular to a gantry crane traverse mechanism. Background technique [0002] Gantry crane is a commonly used lifting equipment. When the gantry crane is moved horizontally, it is necessary to use the gantry crane lateral movement equipment. The advantages of good stability and long service life can meet the requirements for the stable lateral movement of the gantry crane. However, for the existing gantry crane lateral movement equipment, on the one hand, when in use, the moving track is exposed on the outside , it is easy to cause sundries to fall to the inner side of the track, which hinders the movement of the gantry crane. A group of synchronous motors drives the two sides of the gantry crane to move. Once the two groups of motors fail, it is easy to cause inconsistent displacement on both sides, and it is easy to cause damage to the guide rail and card wheel, whi...

[0002] Gantry crane is a commonly used lifting equipment. When the gantry crane is moved horizontally, it is necessary to use the gantry crane lateral movement equipment. The advantages of good stability and long service life can meet the requirements for the stable lateral movement of the gantry crane. However, for the existing gantry crane lateral movement equipment, on the one hand, when in use, the moving track is exposed on the outside , it is easy to cause sundries to fall to the inner side of the track, which hinders the movement of the gantry crane. A group of synchronous motors drives the two sides of the gantry crane to move. Once the two groups of motors fail, it is easy to cause inconsistent displacement on both sides, and it is easy to cause damage to the guide rail and card wheel, which is not conducive to ensuring the safety of the gantry crane. On the other hand, when After a long period of use, once a slight depression appears in the foundation, it is easy to cause the drive screw to be bent, which is not conducive to ensuring the safety of the gantry crane.
