Hoisting machine cross beam translation device

Abstract

The invention discloses a horizontal beam translation device of a crane, in which a sliding oil cylinder support is fixed on both sides below the connecting end of the beam and a column, two sets of hydraulic oil cylinders are arranged in the middle of the sliding oil cylinder support, and the two ends of the hydraulic oil cylinder are fixed On the sliding support, there is a locking device between the two sets of hydraulic cylinders, and a locking track parallel to it between the two sets of hydraulic cylinders. The upper part of the hydraulic cylinders in the beam is equipped with a pumping station of a lateral movement mechanism, and the pumping station is connected to the cylinder pipeline. , the sliding oil cylinder support is provided with a hinge support near the middle of the main beam, the upper part of the hinge support is fixed to the beam, and the lower sliding surface of the hinge support is a polytetrafluoroethylene plate fixed at the bottom of the hinge support. The lower sliding surface of the seat is in contact with the lower sliding plate below it, and the bottoms on both sides of the hinge support are in contact with the sliding pressure plate, and the lower sliding plate and the vertical beam of the sliding pressure plate are axially fixed on the column. Moving mode, stable movement, good overall support of the crane, simple structure, good stability and convenient operation.

Description

technical field [0001] The invention belongs to the technical field of cranes, in particular to a crane beam translation device. Background technique [0002] At present, whether it is a gantry crane or a mobile crane, in order to adjust the hoisting position, the existing cranes generally use the overall movement of the crane, or use the hoist to move on the beam. The overall movement of the crane is supported by the movable connection between the crane and the track. In this way, the overall support of the crane cannot meet the requirements of large-tonnage hoisting, while the hoist can only move along the direction of the beam when the hoist is on the beam-moving crane. The structures of the two methods determine that objects of large tonnage cannot be lifted. Contents of the invention [0003] The object of the present invention is to improve the deficiencies of the prior art and provide a crane beam translation device that adopts beam sliding mode, moves smoothly, has...

[0002] At present, whether it is a gantry crane or a mobile crane, in order to adjust the hoisting position, the existing cranes generally use the overall movement of the crane, or use the hoist to move on the beam. The overall movement of the crane is supported by the movable connection between the crane and the track. In this way, the overall support of the crane cannot meet the requirements of large-tonnage hoisting, and the hoist can only move along the direction of the beam when the hoist is on the beam mobile crane. The structures of the two methods determine that objects of large tonnage cannot be lifted.
