Problems solved by technology

[0002] Double-girder bridge crane (crane) is an indispensable core equipment in the production of enterprises. It has become an important part of the main equipment on the production line. Considering the purchase and maintenance costs and installation space, the lifting weight of the crane in the general factory is based on During routine production and maintenance, it is necessary to design the weight of the lifting object. For some large items that need to be lifted occasionally, the lifting capacity of a single crane cannot meet the requirements. Using a truck crane sometimes requires a lot of auxiliary work due to site constraints. Such as building Dalin, dismantling some equipment, etc., will bring a lot of trouble to the lifting of large pieces
[0003] In order to solve the problem of insufficient lifting capacity of a single crane and meet the production needs of enterprises, it is necessary to invent an intermediate transition tool for lifting large parts with double cranes.

Embodiment 1

[0035] The present invention is a kind of tooling for hoisting and transporting large parts with double cranes, which includes a main beam formed by welding two side-by-side H-shaped steel 1 along the upper and lower flanges, and the side of the flange that is welded on each H-shaped steel 1 A number of lining plates 4 are welded on the "匚"-shaped part; two driving lugs 2 are welded symmetrically on the upper side of the main girder along the longitudinal centerline of the main girder, and a large lifting lug 3 is welded in the middle of the lower part; Both sides of the two driving lugs 2 and the large lifting lug 3 are respectively symmetrically welded with ribs 5, and the bottom of each rib 5 is welded and fixed to the upper surface of the flange of the H-shaped steel 1 of the main beam. The present invention uses H-shaped steel 1 as the material of the main girder, and fully utilizes its characteristics such as light weight, high strength, high stability, and ease of machin...

Embodiment 2

[0040] The present invention is a kind of method for making the tooling used in the above-mentioned embodiment for double-travel hoisting and transporting large pieces, comprising the following steps:

[0041] 1) Determine the length of the two H-shaped steels 1 constituting the main girder according to the safety distance when the two vehicles run parallel, and determine the height and width of the liner 4 according to the thickness and height of the flanges of the two H-shaped steels 1; at the same time, Prepare two driving lugs 2, large lifting lugs 3 and several ribs 5 with grooves on the bottom;

[0042] 2), remove oil stains and surface rust on the outer surfaces of the two flanges of the selected two H-shaped steels 1, and then correct the two H-shaped steels 1 and cut each H-shaped steel 1 by a semi-automatic flame cutting machine. One-sided V-shaped grooves are respectively made on the same side of the flange, and then straightened by flame and polished with an angle ...

Abstract

The invention discloses a tool for lifting big pieces for double travelling cranes. The tool comprises a main beam, wherein the main beam is formed in a way that two parallel H-shaped beams are weldedalong upper and lower flanges, and a plurality of lining plates are welded in the U-shaped position of the flange, which is welded, on each H-shaped beam; two travelling crane lifting lugs are symmetrically welded above the main beam from left to right along the longitudinal center line of the main beam, and a big piece lifting lug is welded in the middle below the main beam; and rib plates are symmetrically welded respectively on both sides of the two travelling crane lifting lugs and the big piece lifting lug, and the bottoms of the rib plates are fixedly welded with the upper surface of the flanges of the H-shaped beams of the main beam. The invention further discloses a manufacturing method of the tool for lifting the big pieces for the double travelling cranes. By applying the tool,two travelling cranes can be used for lifting the big pieces in parallel, the tool has the advantages of rapidity, convenience, safety, low investment cost and high working efficiency, the onsite actual demand can be satisfied, and the production cost is reduced.
