Problems solved by technology
There are certain defects in this kind of driving structure: it is necessary to find the center point of the beam, and then hook it with a hook. If the center point of the beam is not found, it is easy to cause the beam to be out of balance and tilt during the process of transporting the beam. If there is an imbalance, it is easy for the beam to slip from the hook and hit the ground, resulting in casualties and a very large safety hazard

The invention belongs to the technical field of crane maintenance, and particularly relates to a special train for a crane. The train comprises a movable rack, a climbing mechanism and two control mechanisms which are symmetrically arranged on two sides of the climbing mechanism, wherein rollers are arranged at the bottom of the movable rack; the control mechanism comprises a supporting table, a rotary plate, a connecting rod, a driving rack, a gear, a driven rack, a sucker and a clamping part; when the climbing mechanism moves upward along with a cross beam, the rotary plate rotates upward, and the clamping part is opened; when the cross beam is sucked by the sucker, the rotary plate rotates downward, and the clamping part is closed. According to the scheme, the center point of the crossbeam is not required to be searched, the cross beam is effectively prevented from hitting the ground in the moving process, and the cross beam moving safety of a crane can be improved.
Description
technical field [0001] The invention belongs to the technical field of crane maintenance, and in particular relates to a crane special crane. Background technique [0002] Some working characteristics of lifting equipment are intermittent movements, that is, in a working cycle, the corresponding mechanisms for retrieving, moving, unloading and other actions work alternately. The development and use of cranes in the market are becoming more and more extensive. Common cranes are mainly composed of beams, cart running mechanism, trolley running mechanism, lifting mechanism and electrical equipment, among which the beam plays a vital role in the working efficiency and safe operation of the whole crane. In order to ensure the safe operation of the crane, it is often necessary to repair and maintain the beam of the crane. In order to ensure the load-bearing capacity of the crane, the material of the beam is mostly metal alloy. In the process of repairing the beam, it is often ne...
