Description
Technical field
The utility model is related to mine equipment, and in particular to a kind of mine hydraulic bracket is slipped after drawing very heavy to be connected with round-link chain
Device.
Background technology
At present, domestic hydraulic support slips very heavy and round-link chain connection after drawing, universal to be attached more using chain link deck,
As shown in Figure 1.Chain link deck is casting, heavier mass, is unfavorable for the control of enterprise's production cost；Additionally by chain link deck
It is attached, Comparision is cumbersome, is unfavorable for being rapidly assembled and disassembled for underground labour.
The content of the invention
The purpose of this utility model is to provide a kind of simple in construction, convenient disassembly, lower-cost mine hydraulic bracket and drawn
After slip very heavy and circular ring chain connection apparatus.
The technical solution adopted in the utility model is：A kind of attachment means, including jack piston club head, circle are slipped after drawing
Loop chain, bearing pin, split pin；Jack piston club head is slipped after the drawing provided with round-link chain groove, one end of round-link chain is assembled to
Slipped after drawing in the round-link chain groove of jack piston club head；Slip and set between jack piston club head and round-link chain after the drawing
There is bearing pin；The bearing pin top is provided with split pin.
Further, the split pin is the split pin to locking pin axle.
Further, the size of the round-link chain groove and one end of round-link chain match.
Further, the bearing pin is passed across to slip after drawing and set between jack piston club head and round-link chain.
Further, the bearing pin is cylinder or square column type.
Advantage of the present utility model：
The utility model is simple and reliable for structure, and installation, convenient disassembly, cost are relatively low, and technique is simple, and maintenance cost is low, just
With popularization and application.
In addition to objects, features and advantages described above, the utility model also has other purposes, feature and excellent
Point.Below with reference to figure, the utility model is described in further detail.
Brief description of the drawings
The accompanying drawing for constituting the part of the application is used for providing further understanding to of the present utility model, of the present utility model
Schematic description and description is used to explain the utility model, does not constitute to improper restriction of the present utility model.
Fig. 1 is the current domestic attachment means connected by chain link card generally used；
Fig. 2 is the structural representation of the attachment means of the utility model embodiment.
Reference：
1 be draw after slip jack piston club head, 2 be round-link chain, 3 be bearing pin, 4 be split pin, 11 be piston rod head,
12 it is the first bearing pin, 13 be chain link card, 14 be the second bearing pin, 15 is the first round-link chain.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain this
Utility model, is not used to limit the utility model.
With reference to Fig. 2, a kind of attachment means as shown in Figure 2, including slipped after drawing jack piston club head 1, round-link chain 2,
Bearing pin 3, split pin 4；Jack piston club head 1 is slipped after the drawing provided with round-link chain groove, one end of round-link chain 2 is assembled to
Slipped after drawing in the round-link chain groove of jack piston club head 1；Slipped after the drawing jack piston club head 1 and round-link chain 2 it
Between be provided with bearing pin 3；The top of bearing pin 3 is provided with split pin 4.
The split pin 4 is the split pin 4 to locking pin axle 3.
The size of the round-link chain groove and one end of round-link chain 2 match.
The bearing pin 3 is passed across to slip after drawing and set between jack piston club head 1 and round-link chain 2.
The bearing pin 3 is cylinder or square column type.
This practical principle：By round-link chain one end, the round-link chain groove that jack piston club head is slipped after drawing is assembled to
It is interior, corresponding bearing pin is then plugged, and use opening pin locked, that is, complete connection.
This kind of connected mode mainly by improve draw after slip very heavy piston rod head structure, make it is very heavy can be with round-link chain
Directly connected by bearing pin, do not use chain link card.
This practical attachment means, by improving the head construction of original jack piston rod so that jack with
Round-link chain only just can fast and effectively complete connection with a bearing pin.
The utility model is simple and reliable for structure, and installation, convenient disassembly, cost are relatively low, and technique is simple, and maintenance cost is low, just
With popularization and application.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc. should be included in guarantor of the present utility model
Within the scope of shield.
