Abstract
The invention provides a small crane main beam. The small crane main beam comprises transverse beams, auxiliary plates and main beams, wherein each main beam is formed by cutting the whole high-quality I-shaped steel into a proper length; the length can be optionally set according to the needs; strip-shaped holes which are symmetrically distributed are formed in the upper end of each main beam; a bevel angle of 30 degrees is formed between each of two ends of the lower part of each main beam and the horizontal direction; two main beams in one group and the transverse s form a rectangle; the transverse beams are welded at two ends of the main beams through channel steel, positioning holes are formed in the side faces of the transverse beams, fixing plate holes are formed in the upper surfaces of the transverse beams, and two ends of the lower sides of the transverse beams are connected with the auxiliary plates; each auxiliary plate is a steel plate with the thickness of 10mm, is provided with two strip-shaped holes, has the same width as each main beam and is respectively fixed on four bevel angles of the main beams. The existing profiles are ingeniously utilized, the small crane main beam is reasonable in layout, uniform in stress and simple in processing technology, the cost is reduced, and the overall strength is improved, so that the service life is prolonged, the operating safety is improved, the lengths of the main beams are flexible and variable, and the small crane main beam can be matched with different mines and plants and is simple in mounting process and reasonable in design.
Description
Technical field
The invention belongs to crane field, especially a kind of minor crane girder.
Background technology
At present, hoisting crane is all the design of fixed single, length and width are fixed, crossbeam and main beam design complexity, tooling cost is high, and industrial and mining enterprises are due to scale difference, space, place is different, this just needs different, more suitably hoisting crane, even often need special processing and manufacturing, and traditional design, when change one place's part, other parts all will be changed, what have will change processing technology, which adds design and tooling cost, and the design of existing crane girder and crossbeam is complicated, tooling cost is high, Fabrication procedure is complicated, very unfavorable to popularizing of hoisting crane.
Summary of the invention
The object of the present invention is to provide that a kind of structure is simple, convenient and practical, tooling cost is low, length-flexible is adjustable and be particularly useful for the minor crane girder in the little place of industrial and mining enterprises.
Technical scheme of the present invention:
Advantage of the present invention and good effect are:
1, a kind of minor crane girder comprises crossbeam, accessory plate, girder, girder be whole through cutting the high-quality I-beam section of applicable length, its length can need to intercept arbitrarily according to scene, its upper end has the strip hole be arranged symmetrically with, two ends, bottom and horizontal direction are cut into 30 ° of oblique angles, and two one group forms a rectangle with crossbeam; Crossbeam is welded on girder two ends by channel-section steel, and its side has knock hole, opens fixing plate hole above, and following two ends are connected with accessory plate, and accessory plate is the steel plate of thick 10mm, and has 2 strip holes, wide with girder, is fixed on 4 oblique angles of girder.The present invention is ingenious utilizes existing section bar, rational deployment, and processing technology is simple, reduces productive costs, uniform force, increase bulk strength thus increase the service life and improve safety, girder length-flexible is variable, be applicable to different mines and factory, mounting process is simple, reasonable in design.
2, the present invention is pure physical construction, not only long service life, good reliability, also have processing technology simple, without plurality of advantages such as specialized maintenance, low, lightweight, the convenient installations of cost.
3, use the present invention to carry out in-site installation, wall can be fixed on bar hole in its one end, and the other end is fixed on column, save space, make hoisting crane more close to material and scene, transportation range can be shortened, cost-saving, alleviate the labour intensity of staff.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
1-crossbeam in figure; 2-accessory plate; 3-girder.
Detailed description of the invention
A kind of minor crane girder comprises crossbeam 1, accessory plate 2, girder 3, girder 3 is formed through cutting suitable length by whole high-quality I-beam section, length can need to intercept arbitrarily according to scene, its upper end has the strip hole be arranged symmetrically with, oblique angle is cut into from the horizontal by 30 ° of angles in two ends, bottom, two one group forms a rectangle with crossbeam 1, crossbeam 1 is welded on girder 3 two ends by channel-section steel, its side has knock hole, open fixing plate hole above, following two ends are connected with accessory plate 2, accessory plate 2 is steel plates of thick 10mm, and have 2 strip holes, wide with girder 3, be fixed on 4 oblique angles of girder 3.The present invention is ingenious utilizes existing section bar, rational deployment, uniform force, and processing technology is simple, reduce costs, add bulk strength thus increase the service life and improve safety, girder length-flexible is variable, be applicable to different mines and factory, mounting process is simple, reasonable in design.
Principle of work of the present invention:
As shown in Figure 1, a kind of minor crane girder is by crossbeam, accessory plate, girder forms well-set rectangle, girder is as track, it installs crane carriage, dolly can lifting heavy, then move to the other end and unload weight, the crossbeam of minor crane girder and girder is ingenious utilizes existing section bar, rational deployment, uniform force, processing technology is simple, reduce cost, increase bulk strength thus increase the service life, girder length-flexible is variable, be applicable to different mines and factory, mounting process is simple, reasonable in design, and weight-lifting equipment is widely applied.
