Abstract
The utility model discloses a prevent stock tray device that collapses, including the stock, the stock passes through the rope to be fixed on the roof of country rock below in the shaft bottom tunnel, the upper end of stock is passed in the roof embedding country rock. This prevent stock tray device that bursts off, simple structure easily makes and the cost is lower, and the accessible prevents directly from the country rock after the stock became invalid and bursts off on fixing the stock on the roof of country rock below, avoids taking place the casualty accident.
Description
Technical Field
The utility model belongs to the colliery supporting equipment field relates to a prevent stock tray device that collapses.
Background
When a coal mine tunnel is exploited, once the tunnel is excavated, the stress of surrounding rocks is out of balance. In order to maintain the balance state of the rock, the stress is redistributed, and if the strength of the rock is insufficient in the distributing process, the surrounding rock loses stability, and the roadway is damaged. Therefore, control measures must be taken with respect to the surrounding rock.
At present, most mines adopt anchor rods to control surrounding rocks, namely anchor rod supporting, along with the continuous increase of mining depth, mine pressure is more complex and changeable, the deformation of surrounding rocks of a roadway is more difficult to control, once the strength of the anchor rod supporting cannot adapt to the pressure of the surrounding rocks, the anchor rods can fail to collapse out of the surrounding rocks, and casualty accidents can be caused very easily. Therefore, how to prevent the anchor rod from collapsing and ensure the safety of underground operators is a problem which needs to be solved urgently in most mines.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a prevent stock tray device that collapses for collapse from the country rock after avoiding the stock inefficacy, cause the casualty accident.
The utility model provides a technical scheme who adopts is, a prevent that stock tray collapses device, including the stock, the stock passes through the rope to be fixed on the roof of country rock below in the shaft bottom tunnel, and in the roof was passed and the country rock was embedded to the upper end of stock, the stock contained the external screw thread section, the screw thread was equipped with the nut in the external screw thread section, and the cover is equipped with the tray on the stock, the tray is located the top of nut, the quotation top of tray are at the lower surface of roof, and the upper end top of nut is in the bottom of tray.
The utility model is also characterized in that,
the lower end of the anchor rod is provided with a through hole, the rope penetrates through the through hole, and two ends of the rope are respectively fixed on the top plate.
The lower surface of the top plate is provided with two joists or metal nets for tying ropes, and two ends of each rope are tied to one joists or metal nets respectively.
The bottom of tray is provided with the aligning groove, the equipartition has a plurality of aligning balls in the aligning groove.
The rope is a steel wire rope with the diameter not less than 6 mm.
The utility model has the advantages that: the utility model discloses a prevent that stock tray collapses device, simple structure, easily make and the cost is lower, and the accessible prevents directly from collapsing from the country rock after the stock became invalid on fixing the roof of country rock below the stock, avoids taking place the casualty accident.
Drawings
Fig. 1 is a schematic structural view of the device for preventing the anchor rod tray from collapsing.
In the figure: 1. anchor rod, 2 external screw thread section, 3 anchor rod tray, 4 nut, 5 aligning ball, 6 steel wire rope, 7 steel bar joist, 8 roof.
Detailed Description
The technical solution of the present invention will be further described in detail with reference to the accompanying drawings and the detailed description.
As shown in fig. 1, the utility model discloses a prevent stock tray device that collapses, including stock 1, stock 1 passes through rope 6 to be fixed on roof 8 of country rock below in the shaft bottom tunnel, and in roof 8 and embedding country rock were passed to the upper end of stock 1, stock 1 contained external screw thread section 2, and external screw thread section 2 goes up the screw thread and is equipped with nut 4, and the cover is equipped with tray 3 on stock 1, and tray 3 is located the top of nut 4, tray 3's quotation top is at the lower surface of roof 8, and the upper end top of nut 4 is in the bottom of tray 3.
It should be noted that generally can set up a plurality of roofs 8 in the tunnel country rock below in colliery, generally all can install a plurality ofly on every roof 8 the utility model discloses a prevent that stock tray collapses device for support and fix it, unless the installation prevent that stock tray collapses the whole inefficacy of device and can't form the support, roof 8 just can fall.
As shown in fig. 1, the utility model discloses a prevent stock tray device that collapses, its principle lies in: for a single anchor rod tray collapse prevention device, after the anchor rod 1 of the anchor rod tray collapse prevention device fails, and when the anchor rod 1 tends to collapse from surrounding rocks, the anchor rod 1 is fixed on the top plate 8 through a steel wire rope with the diameter not smaller than 6mm, so that the anchor rod 1 can be supported to a certain extent, and the purpose of preventing the anchor rod 1 from directly falling due to failure and avoiding casualties is achieved.
The utility model discloses an among the device of preventing stock tray from collapsing, the cover is equipped with tray 3 on stock 1, and tray 3 passes through nut 4 fastening at the lower surface of roof 8, can play better fastening and supporting role to tray 3, has further strengthened the security performance.
As shown in fig. 1, in the device for preventing a tray of an anchor rod from collapsing of the present invention, as a preferred technical solution of the anchor rod 1, a through hole may be provided at the lower end thereof, and the rope 6 may pass through the through hole and fix both ends of the rope 6 on the top plate 8, respectively, and it should be noted that the through hole may also be provided in the middle of the anchor rod 1 or other positions.
Above-mentioned stock 1's design, its structure is comparatively simple, and easy dismounting can also play fine restriction effect.
As shown in fig. 1, the utility model discloses an in preventing stock tray caving in device, as the preferred fixed mode of rope 6, can be used for the joist 7 of rope in two of the lower fixed surface of roof 8, the both ends of rope 6 are respectively can accomplish fixedly on a joist 7, and it is convenient to dismantle, and stability is better, less intensity of labour greatly.
Therefore, the utility model discloses a prevent that stock tray collapses device, its overall structure is simple, easily makes and the cost is lower, and the accessible prevents directly from collapsing from the country rock after 1 became invalid of stock with stock 1 fix on roof 8 of country rock below, avoids taking place the casualties accident.
