Abstract
The utility model provides a development cover support under coal mine. The utility model aims at horizontal layered coal mining method of existing cover support or solves the problem of difficult when coal layer thickness or inclination angle changes. The development cover support under coal mine comprises a pedestal (1); a crawler belt apparatus (2) is connected to the lower part of the pedestal; the pedestal is connected with a column (4) through a rotating shaft (3); the column is connected to a top frame; and a hydraulic oil cylinder (6) is connected between the column and the pedestal. The development cover support under coal mine in the utility model is used for temporary cover when a fully-mechanized coal winning machine works.
Description
Technical field:
The utility model relates to a kind of coal mining equipment, is specifically related to tunnel shield support under a kind of coal mine.
Background technology:
Stope at half-edge coal seam generally need to be installed shield support, and goaf and working space are separated, and the workman carries out back production under support shielding.In section, across pitch is divided into the band of 20～30m, and 4 milling coal holes at a distance of 6m of driving, connect section haulage way and tailgate in each band.Expand in advance lane in tailgate and install a long 24m, wide than the little 0.5m of coal seam thickness with interior shield support.Adopt the coal that falls and certainly slip to haulage way through milling coal hole, along with back production, shield support is caving the thrust of rock by deadweight and top, along tilting automatically to move down, until adopted whole bands.Last striking.The engineering quantity of this driving method tunnelling is large, and coal dust is large, and condition of labor is poor.And need the shield support autonomous under this situation, exploitation difficulty while for horizontal slicing or coal seam thickness and inclination angle, changing.
Summary of the invention:
The purpose of this utility model is that the problem for above-mentioned existence provides under a kind of coal mine and tunnels shield support, shield support can controlledly be advanced, be applicable to different coal seam thicknesses and the variation at inclination angle, make the down-hole drivage efficiency be improved, and its safety also greatly improves.
Above-mentioned purpose realizes by following technical scheme:
Tunnel shield support under coal mine, comprise base, connecting band track device below described base, connect column by rotating shaft on described base, and described column connects upper frame, connecting fluid compressing cylinder between described column and described base.
Tunnel shield support under described coal mine, described upper frame comprises the crossbeam that is connected with described column, and one group of top board is installed on described crossbeam.
Beneficial effect:
1. the utility model adopts crawler attachment as the drive disk assembly that advances, because crawler attachment can overcome under coal mine with a varied topography, the situation that environment is abominable, mobility strong, so guaranteed job stability, trafficability characteristic to not base slab and leaping over obstacles is also better, rock-steady structure is also fine to the applicability of inclined shaft, after fully-mechanized digging machine driving one end distance, control the shield support of the present utility model end distance of advancing, the exploitation work safety of being convenient to down-hole carries out, connect column by rotating shaft on base of the present utility model simultaneously, described column connects upper frame, connecting fluid compressing cylinder between described column and described base, can be by the extension and contraction control column of controlling hydraulic jack and the angle that base forms certain inclination, the less distance thereby the drive top board moves forward at any time, can adapt to the shielding of small distance, security performance is high.
2. one group of top board is adopted at top of the present utility model, is convenient to change, keep in repair.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
In figure: 1, base, 2, crawler attachment, 3, rotating shaft, 4, column, 5, crossbeam, 6, hydraulic jack, 7, top board.
The specific embodiment:
Embodiment 1:
As shown in Figure 1: tunnel shield support under coal mine of the present utility model, comprise base 1, connecting band track device 2 below described base, connect columns 4 by rotating shaft 3 on described base, described column connects upper frame, connecting fluid compressing cylinder 6 between described column and described base.
Embodiment 2:
Tunnel shield support under the described coal mine of embodiment 1, described upper frame comprises the crossbeam 5 that is connected with described column, and one group of top board 7 is installed on described crossbeam.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises by above technical characterictic and is equal to the technical scheme that replacement forms.Unaccomplished matter of the present utility model, belong to those skilled in the art's common practise.
Claims (2)
1. tunnel shield support under a coal mine, comprise base, it is characterized in that: connecting band track device below described base connects column by rotating shaft on described base, described column connects upper frame, connecting fluid compressing cylinder between described column and described base.
2. tunnel shield support under coal mine according to claim 1, it is characterized in that: described upper frame comprises the crossbeam that is connected with described column, and one group of top board is installed on described crossbeam.
