Abstract
The utility model discloses a coal mine blasting mining face vehicle withstanding device, which is characterized in that a holding pile is disposed on a tunnel base plate and on one side of a conveyor; the holding pile is a plate body disposed on the tunnel base plate; columnar blind holes are disposed in a surface of the plate body; hydraulic pillars are arranged with bottom ends pressed against the columnar blind holes in the holding pile and the top ends pressed against a tunnel top plate; a push jack is disposed between the holding pile and the conveyor; the top end of the push jack is pressed against a side part of the conveyor; and a pedestal of the push jack is fixed to a side part of the holding pile. The coal mine blasting mining face vehicle withstanding device realizes pushing and rolling of the conveyor and automatic movement through retraction of the jack via remote flow feed, thereby saving time and power, improving working efficiency greatly, reducing labor intensity, and protecting workers.
Description
Technical field
The utility model relates to the applied car device that supports in the blast mining face in coal mine pushing and sliding operation.
Background technology
At present, the pushing and sliding operation is to be crossbeam with the i iron on the China's coal-mine blast mining face, and the mode of using hydraulic prop to support car advances.In actual the use, because hydraulic prop and i iron are rigid components, the position that offsets is easy to skid, and skids in case produce, and the casualty accident that flies out is unavoidable; On the other hand, because installation site and form limits, when using hydraulic prop to realize to car, move very inconvenience to car, cause to the car time longlyer, it is passive to have caused to production.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, provide a kind of operating process not only to save time but also laborsaving, can increasing work efficiency effectively, guarantee that the colliery working face of keeping the safety in production supports the car device.
The utility model technical solution problem adopts following technical scheme:
The design feature that the utility model colliery working face supports the car device is:
On roadway floor, the side that is positioned at transporter is provided with overlord's stake, said overlord's stake is the plate body that is placed on the roadway floor, on the surface of plate body the column blind hole is arranged; Hydraulic column is set, and the bottom of said hydraulic column is butted in overlord's stake in the column blind hole, and the top of hydraulic column is butted on back; Between said overlord's stake and transporter, the passing jack is set, the top of said passing jack is butted on the sidepiece of transport vehicle, and the base of passing jack is fixed in the sidepiece of overlord's stake.
Compared with present technology, the utility model beneficial effect is embodied in:
The utility model is to cooperate with overlord's stake to pass jack; Utilize stretching of jack to accomplish the pushing and sliding of transporter and support the work that moves certainly of car device through remote feed flow, not only save time but also laborsaving, greatly improved operating efficiency; Reduce labour intensity, guaranteed worker's safety.

Fig. 3 passes jack for the utility model and stretches out view;
Label among the figure: 1 roadway floor; 2 transporters; 3 overlord's stakes; 3a column blind hole; 4 hydraulic columns; 5 backs; 6 pass jack; 7 ribs.
The specific embodiment
Referring to Fig. 1, Fig. 2, in the present embodiment, on roadway floor 1, the side that is positioned at transporter 2 is provided with overlord's stake 3, overlord's stake 3 has column blind hole 3a for to be placed on the plate body on the roadway floor 1 on the surface of plate body; Hydraulic column 4 is set, and the bottom of hydraulic column 4 is butted in overlord's stake 3 among the column blind hole 3a, and the top of hydraulic column 4 is butted on back 5; Between overlord's stake 3 and transporter 2, be provided with and pass jack 6, the top of passing jack 6 is butted on the sidepiece of transporter 2, and transporter 3 is in a side at rib 7 places, and the base of passing jack 6 is fixed in the sidepiece of overlord's stake 3.
The utility model utilizes the flexible car mode of supporting of having broken away from traditional hydraulic prop of hydraulic jack, and capable of expansion and contraction, moving the time of saving increased the working face extraction time, improved and supported car power, makes to transport steadily, advance fast; Adopt remote feed flow effectively to avoid supporting personnel's injury that car skids and causes by pillar.
