Description
Technical Field
The utility model relates to a hydraulic prop field for the colliery, concretely relates to hydraulic prop interlock prevents turning back device.
Background
The two gate groove advanced sections of the coal mine fully mechanized mining face are both defined as rock burst dangerous areas, and the anti-impact work is considered to meet the advanced requirements of the two gate grooves: all adopt the support mode of hydraulic prop cooperation articulated back timber, hydraulic prop cooperation metal articulated back timber support roof, the positive cantilever of articulated back timber uses. In the prior art, each single hydraulic prop is firmly fastened by an anti-falling rope made of two steel wire ropes, the rope head is fixed on a top plate metal net by a hook, the anti-falling effect can be achieved under certain conditions, and when the single hydraulic prop falls or the metal net is corroded and the anti-falling hook deforms and releases, the single hydraulic prop falls easily to hurt people, and the safety measures are not firm.
SUMMERY OF THE UTILITY MODEL
The utility model provides an easy askew problem of falling to current hydraulic prop existence, the utility model provides a hydraulic prop interlock prevents tilting device.
The utility model adopts the following technical proposal:
an interlocking anti-falling device for single hydraulic props is characterized in that two adjacent single hydraulic props are connected in series through an interlocking structure, the interlocking structure comprises a first fixing buckle, a second fixing buckle and an anchor rod, the first fixing buckle and the second fixing buckle respectively comprise a sleeve joint part and a connecting part, the sleeve joint part is sleeved in the middle of the single hydraulic prop, an upper through hole and a lower through hole are formed in the connecting part, two ends of the anchor rod respectively penetrate through the upper through holes of the first fixing buckle and the second fixing buckle, and two ends of the anchor rod are fixed through anchor rod caps, so that the two adjacent single hydraulic props are connected in series;
the second fixing buckle of the front interlocking structure is used as the first fixing buckle of the rear interlocking structure, and the two ends of the anchor rod of the rear interlocking structure respectively penetrate through the lower through holes of the first fixing buckle and the second fixing buckle of the rear interlocking structure and are fixed by anchor rod caps.
Preferably, the first fixing buckle and the second fixing buckle are both made of strip-shaped belts, after two ends of each belt are folded in half, connecting portions are formed at the connecting portions, and the portions surrounded by the middle portions form the sleeving portions.
Preferably, the upper part of the single hydraulic prop is connected with two anti-falling ropes, the top of each anti-falling rope is connected with a hook, and the hook is connected to the metal net of the top plate.
The utility model has the advantages that:
the utility model provides a device is prevented down to hydraulic prop interlocking establishes ties two hydraulic prop that will link to each other through interlocking structure together, can effectually prevent that certain hydraulic prop is askew to hinder the people, simultaneously, cooperates two to prevent down the rope, further strengthens hydraulic prop's protectiveness, strengthens hydraulic prop's reliability and aesthetic property.
Drawings
FIG. 1 is a schematic diagram of a single hydraulic prop interlocking fall prevention device.
Detailed Description
The utility model is described in detail with the following figures:
referring to fig. 1, an interlocking fall prevention device for single hydraulic props, two adjacent single hydraulic props 1 are connected in series through an interlocking structure.
The upper portion of the single hydraulic prop is connected with two anti-falling ropes 2, the tops of the anti-falling ropes are connected with hooks, and the hooks are connected to a metal net of the top plate.
The interlocking structure and the fall prevention rope are protected, and the fall prevention performance of the single hydraulic prop is enhanced.
Interlocking structure includes that first fixed knot 3, the second is fixed to be detained 4 and stock 5, and first fixed knot all includes cup joint portion and connecting portion 6 with the fixed knot of second, and cup joint portion cup joints at hydraulic prop's middle part, is provided with through-hole and lower through-hole on the connecting portion.
The first fixing buckle and the second fixing buckle are both made of strip-shaped belts, after two ends of each belt are folded in half, connecting parts are formed at the connecting parts, and the parts surrounded by the middle parts form the sleeving parts.
The belt utilizes waste belts under the mine, and the anchor rod utilizes a recovered anchor rod, so that the economic cost is saved.
Example 1
The both ends of stock pass the last through-hole of first fixed knot and the fixed knot of second respectively to fix the both ends of stock with stock cap 7, thereby be in the same place two adjacent monomer hydraulic prop series connection.
The second fixing buckle of the front interlocking structure is used as the first fixing buckle of the rear interlocking structure, and the two ends of the anchor rod of the rear interlocking structure respectively penetrate through the lower through holes of the first fixing buckle and the second fixing buckle of the rear interlocking structure and are fixed by anchor rod caps.
Example 2
The both ends of stock pass the lower through-hole of first fixed knot and the fixed knot of second respectively to the both ends of stock are fixed to the stock cap, thereby are in the same place two adjacent hydraulic prop series connection.
The second fixing buckle of the front interlocking structure is used as the first fixing buckle of the rear interlocking structure, two ends of the anchor rod of the rear interlocking structure respectively penetrate through the upper through holes of the first fixing buckle and the second fixing buckle of the rear interlocking structure, and two ends of the anchor rod are fixed through anchor rod caps.
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also belong to the protection scope of the present invention.
