Abstract
A kind of crane pre-assembly method, it is characterized by comprising support bases, walking beam is fixed at support base both ends, traveling wheel is equipped in walking beam, the fixed flexible leveling guide post in walking beam upper end stretches and reinforces fixing by fixation steel plate between leveling guide post and support base, support base middle position is equipped with lift cylinders, lead screw is fixedly mounted on the upper surface of lift cylinders and flexible leveling guide post, and two sides respectively set an end carriage on lead screw, and lift cylinders are hydraulic cylinder or pneumatic linear actuator.Advantages of the present invention: crane pre-assembly method of the present invention, have it is easy to operate, it is easy for assemble or unload, it is time saving and energy saving, save production cost the advantages that.
Description
Technical field
The present invention relates to a kind of crane preassembling toolings, specifically provide a kind of crane pre-assembly method.
Background technique
Existing crane entirety preassembling is usually used first on the ground by the reality between the end carriage at crane girder both ends
The support of several Simple horizontals is respectively welded at distance, for placing end carriage, then by end carriage by the way of spot welding with it is horizontally-supported
It is fixed, finally crane main tank beam is placed again and realizes main beam of crane and end carriage on end carriage, is walked on stage and girder, track and girder
Assembly and welding between all parts, but this traditional method such as requires both ends horizontal to support it there are many defects
Between distance must be just the same with gross data, this just wastes the plenty of time, and assembled speed is slow, low efficiency, and due to water
The levelness of flat support is uncontrollable, so high to horizontally-supported requirement for horizontality, difficulty is increased, and quality can not protect
Card, there is also a degree of waste of material, and there are security risk, product quality be cannot be guaranteed.
Summary of the invention
The purpose of the present invention is to solve above-mentioned technical problems, have provided a kind of crane pre-assembly method.
The present invention provides a kind of crane pre-assembly methods, it is characterised in that: including support base, the fixed row in support base both ends
Walk beam, be equipped with traveling wheel in walking beam, the fixed flexible leveling guide post in walking beam upper end, leveling guide post of stretching and support base it
Between reinforce fixing by fixation steel plate, support base middle position is equipped with lift cylinders, and lead screw is fixedly mounted on lift cylinders and flexible adjusts
The upper surface of flat guide post, two sides respectively set an end carriage on lead screw, and lift cylinders are hydraulic cylinder or pneumatic linear actuator.
Advantages of the present invention:
Crane pre-assembly method of the present invention, have it is easy to operate, easy for assemble or unload, time saving and energy saving, saving is produced into
This advantages that.
Specific embodiment
Embodiment 1
Present embodiments provide a kind of crane pre-assembly method, it is characterised in that: including support base, the fixed walking in support base both ends
Beam, walking beam is interior to be equipped with traveling wheel, the fixed flexible leveling guide post in walking beam upper end, between flexible leveling guide post and support base
Reinforce fixing by fixation steel plate, support base middle position is equipped with lift cylinders, and lead screw is fixedly mounted on lift cylinders and flexible leveling
The upper surface of guide post, two sides respectively set an end carriage on lead screw, and lift cylinders are hydraulic cylinder or pneumatic linear actuator.
