Description
Technical field
The utility model belongs to hoisting machinery process equipment field, particularly the L shaped turner of a kind of crane girder biaxial tension.
Background technology
Crane girder, need to be to welding between upper and lower cover plate and major and minor web in manufacturing process, and will have the higher accuracy of manufacture, and the wheel that guarantee is installed on it can normally move along crane runway.When it is carried out to weld job, need to repeatedly overturn.At present, when crane girder overturns in processing and manufacturing process, adopt artificial and auxiliary appliance to carry out more.Although this method can be overturn, but, for the large crane of lifting capacity, because its girder volume is also too huge, weight is very heavy, when causing crane girder to need reverse welding in manufacturing process, upset difficulty, needs more manpower, sometimes also will assemble personnel temporarily, waste time and energy and have many unsafe factors, meanwhile, in switching process crane girder also easily occur colliding with, distortion, distortion, machining accuracy is reduced, affect machining accuracy, and then cause quality of products; In order to reduce above-mentioned error, to the following process of girder, also to carry out error correction, this must strengthen the input of cost.Upset during crane girder processing and manufacturing, becomes problem of feeling more headache of manufacturing enterprise.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of for crane girder, in processing and manufacturing process, overturn simple in structure, make easily, the personnel that take are few, working strength is low, easy operation, the L shaped turner of crane girder biaxial tension that time saving and energy saving, product quality is guaranteed, safe.
The technical scheme that the utility model is taked for the turning problem solving in crane girder manufacture process is:
The L shaped turner of crane girder biaxial tension, is characterized in that: the first support arm, the second support arm and bearing pin, consist of, between the first support arm and the second support arm, by bearing pin, be fixedly mounted with and become L shapedly, in the outer end of the first support arm and the second support arm, be all fixed with hanger.
And described the first support arm, the second support arm form by web, cover plate, top board, dividing plate, web, cover plate, top board enclose and are solidly installed, and dividing plate is installed in web, cover plate.
And the inner end of described the first support arm is provided with ears connecting plate, the inner end of the second support arm is provided with connecting plate, and the ears connecting plate of the first support arm and the connecting plate of the second support arm fixedly mount by bearing pin.
And, on the hanger being fixedly mounted with in the outer end of the first support arm or the second support arm, shackle is installed.
Advantage and the good effect that the utlity model has are:
1. when the L shaped turner of this crane girder biaxial tension uses, the first support arm is connected by bearing pin with the second support arm, the girder of preparing upset in manufacture process is placed on the first support arm (or second support arm), make the first support arm and the second support arm be close to cover plate and the web of girder, then with crane, sling and be through the steel wire rope of hanger on the first support arm or the second support arm, (or counterclockwise) half-twist clockwise, thereby complete the upset of girder, so not only can alleviate the working strength of operator in manufacturing grider overturning process increases work efficiency, can also be reduced in the error that the torsional deformation in switching process causes, improved machining accuracy, for the security performance of switching process provides guarantee.
2. the L shaped turner of this crane girder biaxial tension, can greatly reduce personal injury accident, safe.
3. the L shaped turner of the utility model crane girder biaxial tension, occurs colliding with in the time of can effectively avoiding crane grider overturning, distortion, distortion, and product quality is guaranteed.
4. the L shaped turner of the utility model crane girder biaxial tension, scientific structure design is reasonable, have simple in structure, make easily, the advantage such as the personnel that take are few, working strength is low, easy operation, time saving and energy saving, product quality is guaranteed, security is high, be a kind of L shaped turner of crane girder biaxial tension with higher innovation.

The specific embodiment
For further understanding utility model content of the present utility model, Characteristic, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
The L shaped turner of crane girder biaxial tension, is comprised of the first support arm 1, the second support arm 3, bearing pin 2, between the first support arm and the second support arm, by bearing pin, is solidly installed, and in the outer end of the first support arm and the second support arm, is all fixed with hanger 5.Shackle 4 is installed on hanger.Because wire line hitch cannot directly be connected with hanger, can be connected by buckle, and the relatively round and smooth wearing and tearing that reduce steel wire rope of shackle.
The first support arm, the second support arm form by web 9, cover plate 10, top board 8, dividing plate 6, web, cover plate, top board are two, web, cover plate, top board mutually enclose and are solidly installed, and dividing plate is installed in web, cover plate, and hanger is installed on the top board of outer end.Dividing plate is that one to four the utility model is two, uniform being installed in web, cover plate.
The inner end that the inner end of described the first support arm is provided with ears connecting plate 7, the second support arms is provided with the ears connecting plate of connecting plate 11, the first support arms and the connecting plate of the second support arm fixedly mounts by bearing pin.
The operation principle of the L shaped turner of the utility model crane girder biaxial tension is as follows:
While needing to overturn in crane girder processing and manufacturing process, according to the size of crane girder, the L shaped turner 2-3 of the utility model crane girder biaxial tension is placed in near ground crane girder to be flipped, crane girder is placed on the second support arm, the first support arm and the second support arm are close to web and the cover plate of girder, then buckle and put on steel wire rope and hang on crane hook being arranged on unloading on the second support arm hanger, now start crane, the second support arm and the first support arm rotate around bearing pin, suspension hook rising, until the first support arm turn over rotate to parallel to the ground, the second support arm rotates to the position that the first support arm starts most, girder is followed to turn over and is turn 90 degrees, complete whole switching process.Upset, moves the same afterwards.According to reverses direction, girder is placed on the first support arm and also can.
