Abstract
The utility model relates to a kind of monorail crane pull bar, comprise knuckle, bearing pin, draw-bar seat, connecting body, described bearing pin is provided with at least two round nuts on one end, on described draw-bar seat, be fixed with the connecting head that sectional shape is convex shape structure, the described connecting head the other end is positioned at connecting body inside, described connecting body can rotate around connecting head, between described connecting head and connecting body, is provided with wear-resistant material layer.The utility model is simple in structure, reasonable in design, by connecting head is set on draw-bar seat, can realizes the draw-bar seat of one end on pull bar and freely rotate, and is convenient to the connection of each parts on monorail crane, can make the applicability of pull bar wider; By multiple round nuts are set on bearing pin, can be simple and quick realize the fastening of bearing pin.
Description
Technical field
The utility model relates to mining equipment field, relates in particular to a kind of monorail crane pull bar.
Background technique
Old pull bar is used for connecting the each large parts of monorail crane, is main stressed member.The connection of domestic monorail crane pull bar adopts ball-type bearing pin more, manufacturing process complexity, and cost is high, and when turning, wearing and tearing are larger.Therefore, be necessary monorail crane pull bar to improve.The new type mining monorail crane pull bar of announcing according to Chinese patent CN203023250U, not only can effectively meet the connection of the each large parts of monorail crane, and can also realize turning to of monorail crane, but this pull bar still has problems, when one end, connecting port of parts in monorail crane is vertical layout, the other end is horizontal arrangement, and the pull bar in this patent just can not satisfy the demands, and in this patent, employing is that axle end baffle plate is fixed bearing pin, is not very reliable like this.For the problems referred to above, a kind of technological scheme of solution is now proposed.
Model utility content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of monorail crane pull bar is provided.
The utility model is to be achieved through the following technical solutions:
A kind of monorail crane pull bar, comprise knuckle, bearing pin, draw-bar seat, connecting body, described bearing pin is provided with at least two round nuts on one end, on described draw-bar seat, be fixed with the connecting head that sectional shape is convex shape structure, the described connecting head the other end is positioned at connecting body inside, described connecting body can rotate around connecting head, between described connecting head and connecting body, is provided with wear-resistant material layer.
As preferably, described connecting head and draw-bar seat welding or one-body molded.
As preferably, the small end of described connecting head is than the little 10mm～50mm of Outside diameter.
As preferably, described wear-resistant material layer is arranged on connecting body internal surface or on connecting head outer surface, and its thickness is 1mm～5mm.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, by connecting head is set on draw-bar seat, can realize the draw-bar seat of one end on pull bar freely rotates, be convenient to the connection of each parts on monorail crane, can make the applicability of pull bar wider; By multiple round nuts are set on bearing pin, can be simple and quick realize the fastening of bearing pin.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1. knuckle; 2. bearing pin; 3. draw-bar seat; 4. round nut; 5. connecting body; 6. connecting head; 7. wear-resistant material layer.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of monorail crane pull bar, comprises knuckle 1, bearing pin 2, draw-bar seat 3, connecting body 5, and described bearing pin is provided with at least two round nuts 4 on 2 one end, can be simple and quick realize the fastening of bearing pin 2.On described draw-bar seat 3, being fixed with sectional shape is the connecting head 6 of convex shape structure, described connecting head 6 the other ends are positioned at connecting body 5 inside, described connecting body 5 can rotate around connecting head 6, the draw-bar seat 3 that can realize one end on pull bar freely rotates, be convenient to the connection of each parts on monorail crane, can make the applicability of pull bar wider.Between described connecting head 6 and connecting body 5, be provided with wear-resistant material layer 7.
Further, described connecting head 5 welds with draw-bar seat 3 or is one-body molded.
Further, the small end of described connecting head 6 is than the little 10mm～50mm of Outside diameter.
Further, described wear-resistant material layer 7 is arranged on connecting body 5 internal surfaces or on connecting head 6 outer surfaces, and its thickness is 1mm～5mm.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
