[0002] At present, the existing container spreaders in the port generally use machining to process the shaft hole and ear plate hole on the small end beam first, and put a margin of 20mm in diameter. After the overall manufacturing and welding of the beam is completed, the overall structure is bored and processed by the gantry milling machine for the shaft hole, the ear plate hole and the plane, so as to ensure that the size of the shaft hole and the ear plate hole meets the requirements of the drawing. Large, and the relative distance between the shaft holes is not easy to guarantee, so the production is more difficult, and the accuracy of the spreader cannot be well guaranteed after the production

[0022] Such as figure 1 and figure 2 Shown is a specific embodiment of the present invention a kind of overall manufacturing method of container hanger spreader, comprises the following steps:
[0023] A. Make auxiliary tooling for spreader:
[0024] a. Prepare two first square tubes 1 and two second square tubes 2, and fix the two first square tubes 1 and two second square tubes 2 into a rectangular underframe by welding. The support devices are welded on the top, the two support devices at the front are both fixed supports 3, and the two support devices at the rear are both adjustment supports 4 for fine-tuning in four directions: front, rear, left, and right;
[0025] b. Weld two support frames 5 respectively on the positions where the two first square tubes 1 are located between the two support devices, and weld side beam supports 6 on the upper surfaces of the four support frames 5, each The upper surface of the side beam support 6 is provided with grooves 7;

Description
technical field [0001] The invention relates to an overall manufacturing method of a container crane spreader. Background technique [0002] At present, the existing container spreaders in the port generally use machining to process the shaft hole and ear plate hole on the small end beam first, and put a margin of 20mm in diameter. After the overall manufacturing and welding of the beam is completed, the overall structure is bored and processed by the gantry milling machine for the shaft hole, the ear plate hole and the plane, so as to ensure that the size of the shaft hole and the ear plate hole meets the requirements of the drawing. Large, and the relative distance between the shaft holes is not easy to guarantee, so the production is more difficult, and the accuracy of the spreader cannot be well guaranteed after production. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide an overall manufacturin...
