Description
Technical field
The utility model belongs to underground coal road driving technology field, more particularly to a kind of to be used to be 5~6.3m, height to width
Spend the advance support of double cutting units anchor driving machines of the tunnel cutting formation for 3.5~5.3m.
Background technology
Coal mining, driving are leading.Coal road drilling depth accounts for more than the 80% of mine total footage, and it is to alleviate ore deposit to do a good job of it coal road drilling depth
Well excavation replacement is nervous, keeps coal mine excavation balance, realizes the key of mine high-yield and high-efficiency.
Develop comparatively fast in terms of coal roadway tunneling technique and equipment, form " fully-mechanized digging machine --- monomer jumbolter operation
Line ", " fully-mechanized digging machine --- hydraulic anchor rod drill carriage production line ", " continuous milling machine --- hydraulic anchor rod drill carriage production line " and " pick anchor one
A variety of coal roadway tunneling techniques such as machine " and the general layout deposited, guarantee is provided for mine safety production.But all these driving dresses
It is that drivage efficiency does not give full play to for main problem is still suffered from, and restricts safety in production and the high-yield and high-efficiency of mine, improves
It is single imperative into level.
Existing equipment is primarily present one of problem
Continuous milling machine and fully-mechanized digging machine only have tunneling function, not branch protective function, bad adaptability big to unsupported back span：It is only applicable to
The good situation of roof condition, minimum unsupported back span are big, it is impossible to immediate support.
The content of the invention
The utility model aims to solve the problem that the problem of, bad adaptability big to unsupported back span in existing equipment skill, there is provided one kind has
Adaptability is good
To achieve these goals, the technical solution of the utility model is：
A kind of advance support of double cutting units anchor driving machines, including level-one telescopic oil cylinder (903), level-one sleeve (904), two
Level telescopic oil cylinder (905), two-level sleeve (906), push rod (907), top braces (909), the two-level sleeve are inserted into one
In level sleeve, and advance support arm is formed together；Top braces are hinged on push rod 907；The level-one telescopic oil cylinder is one
Outside level sleeve, and it is connected with level-one sleeve, two-level sleeve；The two-stage telescopic cylinder in two-level sleeve, and with level-one set
Cylinder, push rod connection；It is characterized in that：Further include fixed platform (901), overturning oil cylinder (902) and anti-skidding platform (908)；Wherein：
The level-one sleeve is hinged in fixed platform, and the anti-skidding platform is connected with fixed platform, anti-skidding platform and fixed platform
On the cantilever segment of cutting units；The overturning oil cylinder is hinged on fixed platform and level-one sleeve.
Compared with prior art, advance support turns round and carries out immediate support the utility model with cutting units, in cut operation
Shunk during with walking, solve the big safety problem of unsupported back span so that operating personnel is safer.
Brief description of the drawings
Fig. 1 is the utility model advance support front view.

Embodiment
As depicted in figs. 1 and 2, a kind of advance support of double cutting units anchor driving machines of the utility model, including fixed platform
901st, overturning oil cylinder 902, level-one telescopic oil cylinder 903, level-one sleeve 904, two-stage telescopic cylinder 905, two-level sleeve 906, push rod
907th, anti-skidding platform 908, top braces 909；The anti-skidding platform 908 is connected with fixed platform 901, anti-skidding platform 908 with
Fixed platform 901 is installed on the cantilever segment of cutting units；The level-one sleeve 904 is hinged in fixed platform 901, two level set
Cylinder 906 is inserted into level-one sleeve, and forms advance support arm together；The top braces 909 are hinged on push rod 907；
The level-one telescopic oil cylinder 903 is connected outside level-one sleeve, and with level-one sleeve, two-level sleeve 906, i.e.,：One
The cylinder body of level telescopic oil cylinder 903 is hinged on outside level-one sleeve, and the plunger and two-level sleeve 906 of level-one telescopic oil cylinder 903 are hinged, and one
Level telescopic oil cylinder 903 promotes two-level sleeve 906 to stretch in level-one sleeve 904；
The two-stage telescopic cylinder 905 is connected in two-level sleeve, and with level-one sleeve, push rod 907；I.e.：Two level is stretched
The cylinder body of contracting oil cylinder 905 is hinged in two-level sleeve, and with two-level sleeve, the plunger of two-stage telescopic cylinder 905 in push rod with
Push rod 907 connects；Two-stage telescopic cylinder 905 promotes push rod 907 to stretch in two-level sleeve 906；The top braces 909 with
Connected in push rod 907, top braces 909 are used at the top of supported laneway；
The overturning oil cylinder 902 is hinged on fixed platform 901 and level-one sleeve；Overturning oil cylinder 902 is by advance support
Arm overturns supporting, and is folded on fixed platform 901, in order to which cutting units works.
Holding state of the advance support on the cantilever of cutting units.The advance support of double cutting units anchor driving machines be divided into it is left,
Right advance support, its structure are identical.Left and right advance support is attached separately on the cantilever segment of two cutting units in left and right.
As shown in figure 3, the fundamental diagram of advance support, advance support is in contraction state in driving and walking,
When leting speeper and bolting and rope support operation, the cantilever of cutting units, which is stopped, is placed on low spot, and overturning oil cylinder will on advance support
Advance support upset is vertical state position, and the level-one telescopic oil cylinder of level-one cartridge exterior promotes two-level sleeve, according to different height
Degree, two-level sleeve elongation；Two-stage telescopic cylinder is filled with two-level sleeve, two-stage telescopic cylinder elongation will be that push rod is shifted onto in sleeve
Top, the top plate on such top braces top to tunnel, realizes the top plate protection to job area.
Anti-skidding platform is the operating platform being fixed on the cantilever of cutting units, and operating personnel stand upper, play safety support
Support acts on.Advance support is mainly to realize machinery support net and protect safety of the operating personnel under empty push up, and plays gib
Effect.
