Abstract

The utility model 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

Minor crane girder

Technical field

The utility model belongs to hoisting 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 girder design are complicated, tooling cost is high, and industrial and mining enterprises are because scale is different, space, place is different, this just needs different, hoisting crane more suitably, even often need special processing and manufacturing, and traditional design, when change one place part, other parts all will be changed, what have will change processing technology, design and tooling cost have so just been increased, 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 purpose of this utility model be to provide a kind of simple in structure, convenient and practical, tooling cost is low, length is flexibly adjustable and be particularly useful for the minor crane girder in the little place of industrial and mining enterprises.

The technical solution of the utility model:

Advantage of the present utility model and good effect are:

1, this minor crane girder comprises crossbeam, accessory plate, girder, girder be whole through cutting the high-quality I-beam section that is applicable to length, its length can need intercepting arbitrarily according to scene, its upper end has the strip hole being 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 fixedly plate hole above, and two ends are connected with accessory plate below, the steel plate that accessory plate is thick 10mm, and have 2 strip holes, and wide with girder, be fixed on 4 oblique angles of girder.The utility model is ingenious utilizes existing section bar, rational deployment, and processing technology is simple, has reduced productive costs, stressed even, thereby increase bulk strength, increase the service life and improved safety, girder length flexibility and changeability, be applicable to different mine and factories, mounting process is simple, reasonable in design.

2, this minor crane girder 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 minor crane girder to carry out scene and install, wall can be fixed on bar hole in its one end, and the other end is fixed on column, save space, make hoisting crane can more approach material and scene, shorten transportation range, cost-saving, alleviated staff's labour intensity.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

1-crossbeam in figure; 2-accessory plate; 3-girder.

The specific embodiment

Minor crane girder comprises crossbeam 1, accessory plate 2, girder 3, girder 3 is to be formed through cutting suitable length by whole high-quality I-beam section, length can need intercepting arbitrarily according to scene, its upper end has the strip hole being 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 to be welded on girder 3 two ends by channel-section steel, its side has knock hole, open fixedly plate hole above, two ends are connected with accessory plate 2 below, 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 utility model is ingenious utilizes existing section bar, rational deployment, stressed evenly, processing technology is simple, reduce costs, thereby increased bulk strength, increase the service life and improved safety, girder length flexibility and changeability, be applicable to different mine and factories, mounting process is simple, reasonable in design.

Principle of work of the present utility model:

As shown in Figure 1, minor crane girder is by crossbeam, accessory plate, girder forms well-set rectangle, girder is as track, crane carriage is installed on it, dolly can lifting heavy, then move to the other end and unload weight, the crossbeam of minor crane girder and girder be ingenious utilizes existing section bar, rational deployment, stressed even, processing technology is simple, reduced cost, thereby increasing bulk strength increases the service life, girder length flexibility and changeability, be applicable to different mines and factory, mounting process is simple, reasonable in design, and weight-lifting equipment is widely applied.
