Abstract
The invention discloses the coal-mine hydraulic support of a kind of adjustable support point, it includes base, back timber and jack, described top beam rear end is connected with inclined-plane, described base front upper place is provided with slideway, it is movably equipped with slide on described slideway, being fixed with connection seat on described slide, described jack is movably connected be connected seat, and the top of jack is movably connected with back timber.This hydraulic rack structure is simple and reliable, can require to change Support Position according to Minepit environment.
Description
Technical field
The present invention relates to coal mine machinery field, be specifically related to the coal-mine hydraulic support of a kind of adjustable support point.
Background technology
The 7th, the world of Natural Resources In China total amount row, about 40,000 tons of standard coals of energy resources total amount occupy third place in the world.In
State's coal reserves is 10024.9 hundred million tons.When coal mining, hydraulic support is one of important in coal mining equipment,
Also one of safe necessaries being to ensure that miner, due to the back timber length of hydraulic support, to be that the hole diameter according to mine comes fixed,
When the hole diameter of mine is oversize, needs additionally to increase advanced guard beam in the back timber front end of hydraulic support, ensure miner's
Personal safety.The current hydraulic jack on hydraulic support is all fixed, often can arrange four groups of hydraulic pressure below back timber
Oil cylinder, and this hydraulic support is only suitable for big ore deposit and uses, and then cannot use in little ore deposit, therefore, applicant is just for different
The Coal Mine Design hydraulic support of a kind of adjustable support point, can change Support Position according to practical situation, and easy to operate,
Safety is high.
Summary of the invention
The technical problem to be solved is to provide the coal-mine hydraulic support of a kind of adjustable support point, this liquid
Pressure supporting structure is simple and reliable, can require to change Support Position according to Minepit environment.
The technical problem to be solved realizes by the following technical solutions.
The coal-mine hydraulic support of a kind of adjustable support point, it includes base, back timber and jack, described back timber
Back end activity connects inclined-plane, and described base front upper place is provided with slideway, described slideway is movably equipped with slide, in described cunning
Being fixed with connection seat on Zuo, described jack is movably connected be connected seat, and the top of jack is movably connected with back timber.
Further, described base is also fixed with support seat.
Further, described support seat is movably connected with inclined-plane by support cylinder.
Further, the described seat rear that connects is connected with described support seat by hydraulic jack.
Further, the base in described slide front is additionally provided with limit base.
Compared with prior art, the invention has the beneficial effects as follows: advanced by hydraulic jack and make jack tilt, thus come
The regulation change to mine Support Position；Operation is simple and reliable for the present invention, practical, can enter according to the difference of mine situation
Row sum-equal matrix, thus ensure the personal safety of miner.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram；
Fig. 2 is state diagram of the present invention.
Detailed description of the invention
For the technological means making invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with
It is specifically illustrating, the present invention is expanded on further.
As shown in Figure 1-2, the coal-mine hydraulic support of a kind of adjustable support point, it includes base 1, back timber 2 and thousand
Jin top 3, described back timber 2 back end activity connects has inclined-plane 4, described base 1 front upper place to be provided with slideway 5, and described slideway 5 is lived
Moving and be provided with slide 6, be fixed with connection seat 7 on described slide 6, described jack 3 is movably connected be connected seat 7, and thousand
The top on jin top 3 is movably connected with back timber 2.
Support seat 8 also it is fixed with on described base 1.Described support seat 8 is moving phase with inclined-plane 4 by support cylinder 9
Even.Described seat 7 rear that connects is connected with described support seat 8 by hydraulic jack 10.On the base in described slide front
It is additionally provided with limit base 11.
The ultimate principle of the present invention, principal character and advantage have more than been shown and described.The technical staff of the industry should
Understanding, the present invention is not restricted to the described embodiments, and the simply explanation present invention's described in above-described embodiment and description is former
Reason, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, these changes and improvements
Both fall within scope of the claimed invention.Claimed scope is by appending claims and equivalent circle thereof
Fixed.
