A horizontal adjustment device for the hoisting device of a trackless gantry crane

Abstract

The invention relates to a transverse adjustment device for a lifting device of a trackless portal crane. The transverse adjustment device is characterized in that two adjustment devices (2) are connected to the rack (1), wherein a first adjustment rack (3) and a second adjustment rack (4) are correspondingly connected to the two adjustment devices (2) and connected with a fixing and lifting device (5); each adjustment device comprises a dead plate (6) and a guide slot (7) formed in the dead plate; an adjusting plate (8) is connected to the interior of each guide slot in a sliding and guiding manner; a two-way oil cylinder (9) is fixedly connected to the lower side of each adjusting plate; piston rods on two sides of each two-way oil cylinder are hinged to the corresponding dead plate; an adjustment bar (10) is arranged on the upper side of each adjusting plate; and the adjustment bars are connected with the first adjustment rack or the second adjustment rack. The transverse adjustment device has the following advantages: the lifting device can be horizontally and transversely moved or horizontally swing on a horizontal plane, so that the lifting position accuracy of the lifting device is improved, and positive conditions are provided for lifting goods.

Description

technical field [0001] The invention relates to a track laying equipment, in particular to a transverse adjustment device for a hoisting device of a trackless gantry crane. Background technique [0002] In recent years, my country has gradually become the country with the most railway operating mileage in the world. In order to ensure the high-speed operation of trains, the track structure is required to have a strong integrity. Once the foundation is greatly deformed or the force transmission parts of the track are damaged, the track structure It is difficult to guarantee the stability and smoothness of the train, which may lead to the speed limit of the train, or cause a safety accident. In practical application, during the track construction of railways and subway tunnels, track slabs, sleepers, formwork, rail rows, steel rails and turnouts all need to be hoisted, and track structural components may be damaged during service, and track slabs or Concrete base plate is crac...
