Description
Technical field
The utility model relates to a kind of elevating mechanism, specifically a kind of lifting gear of the two-arm hydraulic anchor rod drill carriage platform for colliery operation.
Background technology
In recent years, because bolt support is a kind of quick, safe, economic colliery tunnel support mode, therefore roofboltier is widely used in coal mining operation.Especially the low price of two-arm colliery hydraulic anchor rod drill carriage, technology maturation, operates fast and convenient, fully can ensure construction safety simultaneously, thus be widely used.Platform lifting mechanism is the requisite ingredient of two-arm colliery hydraulic anchor rod drill carriage, and the height of traditional platform lifting mechanism can not regulate.According to the difference of operating mode, when running into the situation of the too high and ultra-wide in tunnel, the elongation that so two-arm colliery hydraulic anchor rod drill carriage inevitable requirement two-arm is tried one's best is raised and puts wide, when two-arm colliery hydraulic anchor rod drill carriage complete machine width and length because of tunnel operating mode restrained, traditional replacing drilling rod and operation, need external aerial device to operate, and need to move according to drill carriage the position adjusting external aerial device at any time, so not only not easy to operate but also poor stability, efficiency are low.In view of the technical problem existed in prior art, therefore, a kind of new elevating mechanism of exigence solves the problems of the technologies described above.
Summary of the invention
The utility model is just for the technical problem existed in prior art, the platform lifting device of a kind of two-arm colliery hydraulic anchor rod drill carriage is provided, this device when two-arm colliery hydraulic anchor rod drill carriage car load restricted width according to the height of different regulating working conditions platform, overall construction design is ingenious, easy to operate, effectively reduce the labour intensity of operating personnel.
To achieve these goals, the technical solution adopted in the utility model is, a kind of platform lifting device of two-arm hydraulic anchor rod drill carriage, and comprise rotation and walk on stage, telescopic oil cylinder, lifting linking member, lifting is walked on stage, spacing connecting rod.By described spacing connecting rod pivot joint between described lifting is walked on stage and described rotation is walked on stage, form a parallel-crank mechanism, under the effect of described telescopic oil cylinder, described lifting linking member raises or reduces, this parallel-crank mechanism generation deformation, the described lifting relative altitude of walking on stage with described rotation of walking on stage is changed, and then realizes the function of adjustment podium level.Described telescopic oil cylinder and described rotation walk on stage between by pinned connection, walked on stage by lifting described in pinned connection in one end of described lifting linking member, its other end is by telescopic oil cylinder described in pinned connection.The ingenious practicality of whole Technical Design, easy to operate, further increase the mechanization degree of drill carriage.
When the large arm of drill carriage needs to bore top-portion apertures or front square hole, described telescopic oil cylinder pulls described lifting linking member to walk on stage rotation around described rotation by shrinking cylinder body, and under the effect of described spacing connecting rod, described lifting is walked on stage increase, when described lifting walk on stage reach suitable operating position time, lock described telescopic oil cylinder, thus realize free operant.
Improve as one of the present utility model, the quantity of described spacing connecting rod is 4.
Relative to prior art, advantage of the present utility model is as follows, 1) overall structure is simple and reliable, and disassembly and assembly convenient maintenance and replacement, cost are lower; 2) this device can realize freely being elevated of drill carriage lift platform according to different applying working conditions, and integrated operation is easy, and can ensure that drill carriage car load is in a relatively stable safe duty all the time when operation; 3) this device overcomes traditional external aerial device, not only ensure that the personal safety of operating personnel, simultaneously the mechanization degree of also drill carriage.

Detailed description of the invention
In order to deepen understanding and cognition of the present utility model, below in conjunction with accompanying drawing the utility model be further described and introduce.
As Fig. 1-Fig. 3, a kind of platform lifting device of two-arm hydraulic anchor rod drill carriage, comprises rotation and walks on stage 1, telescopic oil cylinder 2, lifting linking member 3, lifting walks on stage 4, spacing connecting rod 5, described lifting walk on stage 4 and described rotation walk on stage between 1 by the pivot joint of described spacing connecting rod 5, form a parallel-crank mechanism, under the effect of described telescopic oil cylinder 2, this parallel-crank mechanism generation deformation, make described lifting walk on stage 4 position change, and then realize adjustment podium level function.Described telescopic oil cylinder 2 and described rotation are walked on stage by pinned connection between 1, and one end of described lifting linking member 3 walks on stage 4 by lifting described in pinned connection, and its other end is by telescopic oil cylinder 2 described in pinned connection.The ingenious practicality of whole Technical Design, easy to operate, further increase the mechanization degree of drill carriage.
As Fig. 1-Fig. 3, improve as one of the present utility model, the quantity of described spacing connecting rod is 4.All the other structures are identical with embodiment 1 with advantage.
As shown in Figure 1, when the large arm of drill carriage is in high-rise working, the oil return of described telescopic oil cylinder 2 and pull described lifting linking member 3 around described rotation walk on stage 1 pin joint rotate, described lifting linking member 3 rises and lifts described lifting and walks on stage 4, meanwhile described spacing connecting rod 5 is followed lifting and is walked on stage 4 and be raised to suitable position, lock the length of described telescopic oil cylinder 2 subsequently, lifting is walked on stage and 4 is in this position all the time until end of operation.
As shown in Figures 2 and 3, when the large arm of drill carriage is in lower operation, the oil-feed of described telescopic oil cylinder 2 and promote described lifting linking member 3 around rotate walk on stage 1 pin joint rotate, described lifting linking member 3 declines and falls lifting and walks on stage 4, and meanwhile spacing connecting rod 5 is followed lifting and walked on stage and 4 drop to extreme lower position.
It should be noted that above-described embodiment, be not used for limiting protection domain of the present utility model, equivalents done on the basis of technique scheme or the alternative scope all falling into the utility model claim and protect.
