Description

The novel long draw structure of a kind of working device of loader and loader

Technical field

The utility model discloses novel long draw structure and the loader of a kind of working device of loader.

Background technology

Along with the demand accounting of working device of loader lengthening swing arm is gradually increased, the design of relatively long draw also gets more and more. But seem simple long draw structure and there is also some problems.At present long draw structure has two kinds of versions, common shape and adding Strong type, there is thickness of slab from heavy problem in plain edition, reinforced there is the big yielding problem of structure complexity welding capacity.Therefore exist Meet under reliability premise, work out a kind of from heavy and light, the simple long draw of technique, be also the research of current working device of loader A problem.

Existing working device of loader long draw structure mainly has two kinds, and one is plain edition (shown in accompanying drawing 1), Yi Zhongshi Reinforced (shown in accompanying drawing 2-1,2-2,2-3).Plain edition pull bar is made up of the round pasting board 2 of draw-bar guide 1 and four；Reinforced is by drawing Bar plate 1, four 2, two reinforcements 3 of round pasting board form:

Existing working device of loader long draw is primarily present following shortcoming:

1) there are two problems in plain edition long draw, and one to be that draw-bar guide 1 steel plate thickness thickness causes conducting oneself with dignity the heaviest, and two is that it is single Plate structure bending resistance difference is yielding；

2) reinforced long draw can solve medium-sized two problems, but there are two reinforcements that new problem is strip Muscle 3 blanking is yielding and welding capacity relatively big (four road weld seams) is easily caused long draw bulk deformation.

Utility model content

This utility model is primarily directed to the deficiencies in the prior art, innovative design from structure, solves prior art and deposits In problem.Compared with plain edition long draw, improve bending resistance, alleviate deadweight, reduce product cost；With reinforced Long draw is compared, decrease component parts quantity, decrease weld seam quantity, avoid two pieces strip reinforcement blanking become Shape, avoid the series of problems such as long draw postwelding bulk deformation.

The technical scheme that this utility model provides is as follows:

The novel long draw structure of a kind of working device of loader, including draw-bar guide, the two ends of draw-bar guide are provided with connection Hole, along the direction at described draw-bar guide axis place, is provided with a coupled cover plate, described lid in the side of draw-bar guide The plane at plate place is mutually perpendicular to the plane at draw-bar guide place.

Further, two ends of described connecting hole are provided with the round pasting board being fitted on draw-bar guide.

Further, described cover plate is respectively symmetrically relative to around draw-bar guide.

Further, described cover plate cross section be shaped as a rectangle, and along draw-bar guide axial direction, rectangle two The width of end is that isoceles triangle shape is gradually reduced.

A kind of loader, its operating position uses long draw to be foregoing long draw structure.

The beneficial effect that technical solutions of the utility model are brought:

The long draw structure of this utility model working device of loader is independent innovational design, solves long draw existing The deficiency of technology；

1, compared with plain edition long draw, the setting of cover plate makes the bending resistance of long draw improve, bending resistance Improve 1.5～2.5 times, pull bar weight reduction 10%～20%, product cost reduce about 15%；

2, compared with reinforced long draw, reduce by 1 part, decrease 2 long weld seams, avoid adding of two pieces strip Strong muscle blanking deforms, avoids the problems such as long draw postwelding bulk deformation, and comprehensive manufacturing cost reduces by 6%～10%.

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will be to embodiment Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, the accompanying drawing in describing below is this Some embodiments of utility model, for those of ordinary skill in the art, on the premise of not paying creative work, also Other accompanying drawing can be obtained according to these accompanying drawings.

Fig. 1, medium-sized long draw structural representation；

Fig. 2-1,2-2,2-3 are reinforced long draw structural representation.

Fig. 3-1,3-2,3-3 are long draw structural representation of the present utility model.

In figure: 1 draw-bar guide, 2 circle pasting boards, 3 reinforcements, 4 cover plates.

Detailed description of the invention

Below in conjunction with the accompanying drawings this utility model is described in detail:

There is various problem, this utility model in existing plain edition pull bar and reinforced pull bar as described in background Solve prior art existing problems；Compared with plain edition long draw, improve bending resistance, alleviate deadweight, reduce Product cost；Compared with reinforced long draw, decrease component parts quantity, decrease weld seam quantity, to avoid two pieces long The reinforcement blanking of strip deforms, avoids the series of problems such as long draw postwelding bulk deformation；Concrete structure is as follows:

Embodiment 1

As shown in Fig. 3-1,3-2,3-3, the novel long draw structure of a kind of working device of loader, including draw-bar guide 1, The two ends of draw-bar guide 1 are provided with connecting hole, are provided with a coupled cover plate 4, the plane at cover plate 4 place at draw-bar guide 1 top It is mutually perpendicular to the plane at draw-bar guide 1 place.

Top described here is according to long draw structure in use, the description that its placement location is carried out, if non- Use state, the concept that top described here is relative,

Further, two ends of described connecting hole are provided with the round pasting board 2 being fitted on draw-bar guide.

Further, described cover plate 4 is respectively symmetrically relative to around draw-bar guide 1.

Further, the thickness of described draw-bar guide 4 is thinner than the draw-bar guide thickness of plain edition pull bar, such as: 20 series The thickness of the existing draw-bar guide of loader is 25mm, and after structure of the present utility model is improved, thickness can be designed to 20mm；30 are The thickness of the existing draw-bar guide of loader of row is 36mm, and after structure of the present utility model is improved, thickness can be designed to 30mm； The thickness of the existing draw-bar guide of loader of 50 series is 50mm, and after structure of the present utility model is improved, thickness can be designed to 45mm；

Further, described cover plate 4 cross section be shaped as a rectangle, and along draw-bar guide axial direction, rectangle The width at two ends is that isoceles triangle shape is gradually reduced.

Embodiment 2

A kind of loader, it uses the long draw structure described in embodiment 1.

This utility model is compared with plain edition long draw, and the setting of cover plate 4 makes the bending resistance of long draw improve, tool Body be bending resistance improve 1.5～2.5 times, pull bar weight reduction 10%～20%, product cost reduce about 15%；

With compared with reinforced long draw, the position of cover plate is different from the position of reinforcement, and if comparing in quantity, subtracts Few 1 reinforcement, decrease 2 long weld seams, avoid the reinforcement blanking deformation of two pieces strip, avoid long draw postwelding The problems such as bulk deformation, comprehensive manufacturing cost reduces by 6%～10%.

Although detailed description of the invention of the present utility model is described by the above-mentioned accompanying drawing that combines, but not new to this practicality The restriction of type protection domain, one of ordinary skill in the art should be understood that on the basis of the technical solution of the utility model, ability Field technique personnel need not to pay various amendments or deformation that creative work can make still at protection model of the present utility model Within enclosing.
