Description
Technical Field
The utility model relates to a mining field, concretely relates to coal mining belt aircraft nose drive division does not have basic base.
Background
The coal mining belt head driving part is formed by fixing a driving part motor and a speed reducer on a 4cm thick steel plate and welding I-shaped steel below the steel plate, and is placed and fixed in the past. The ground level that needs to be cleared up is floated the waste rock and is looked for ground level, digs the foundation pit at ground level's coal bottom plate, then pours concrete and dries (this process is 30 hours consuming time) on the horizon to the foundation pit on the horizon, carries out belt aircraft nose drive unit equipment fixing by the installation team at last, wholly causes like this that installation belt feeder drive unit wastes time and energy, and the cost also has certain potential safety hazard than higher in addition.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems existing in the prior art, the utility model provides a coal mining belt aircraft nose drive division does not have basic base.
The utility model discloses a realize through following technical scheme:
the utility model provides a coal mining belt aircraft nose drive division does not have basic base, is used for placing the coal bottom plate of coal mining belt aircraft nose drive division in the tunnel including the pit, it has a plurality of to be the drilling of square arrangement to open on the coal bottom plate, place the stock that is used for fixed coal mining belt aircraft nose drive division in the drilling, open at the central authorities of stock has central filling hole, evenly open the lower part of stock has the filling hole of a plurality of and central filling hole intercommunication, the drilling lower part is filled through central filling hole and filling hole has the anchoring agent that is used for fixed stock.
Preferably, the top of the central injection hole extends to the top end of the anchor rod, and the bottom of the central injection hole extends to the lower part of the anchor rod.
Preferably, the coal bottom plate is arranged in a leveling mode.
Compared with the prior art, the beneficial effects of the utility model are that: this practicality need not to carry out concrete placement to the fixed process of coal mining belt aircraft nose drive division, and the construction security improves greatly, and the engineering time significantly reduces, also descends by a wide margin to the cost simultaneously, and construction operation is comparatively simple, and the practicality is strong. The device can be recycled, and is more convenient to install and dismantle.
Drawings
FIG. 1 is a schematic view of the knot of the present invention;
FIG. 2 is a cross-sectional view of the anchor rod of the present invention;
FIG. 3 is a schematic view of a conventional mounting structure;
in the figure: the coal bed plate comprises a coal bed plate 1, a drilling hole 2, an anchor rod 3, an anchoring agent 4, a speed reducer 5, a center injection hole 6 and a filling hole 7.
Detailed Description
The invention will be described in further detail with reference to the following detailed description and accompanying drawings:
as shown in fig. 1, 2 and 3, a base of a driving part of a coal mining belt head without a foundation comprises a coal bottom plate 1 used for placing the driving part of the coal mining belt head in an underground roadway, wherein a plurality of drilling holes 2 arranged in a square shape are formed in the coal bottom plate 1, an anchor rod 3 used for fixing the driving part of the coal mining belt head is placed in each drilling hole 2, a central injection hole 6 is formed in the center of each anchor rod 3, a plurality of filling holes 7 communicated with the central injection hole 6 are uniformly formed in the lower part of each anchor rod 3, and an anchoring agent 4 used for fixing the anchor rod 3 is filled in the lower part of each drilling hole 2 through the central injection hole 6 and the filling holes 7.
The top of the center injection hole 6 extends to the top end of the anchor rod 3, and the bottom of the center injection hole 6 extends to the lower part of the anchor rod 3.
The coal bottom plate 1 is arranged in a leveling mode.
The working principle is as follows: when in operation, firstly a tunneling team cleans up the floating gangue and finds the ground level on a coal bottom plate 1 needing to be provided with a driving part of a head of the coal mining belt, a drilling machine is adopted to drill a vertical drilling hole 2 on the coal bottom plate 1, an anchor rod 3 is placed in the drilling hole 2, then, an oil gun filled with an anchoring agent is used for injecting the anchoring agent 4 into a central injection hole 6 at the top of the anchor rod 3, the anchoring agent 4 enters a filling hole 7 at the lower part of the anchor rod 3 through the central injection hole 6 and fills the bottom of the drill hole 2 along the filling hole, like this can be quick effectual the packing of realization anchoring agent 4, guarantee anchor rod 3's quick fixed, anchor rod 3 fixes coal mining belt aircraft nose drive division after fixed the accomplishing, and whole fixed process need not to carry out concrete placement, and the construction security improves greatly, and the engineering time significantly reduces, also descends by a wide margin to the cost simultaneously, and construction operation is comparatively simple, and the practicality is strong. The device can be recycled, and is more convenient to install and dismantle.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
