Description
Technical field
The utility model belongs to Coal-seam Gas Recovery Technologies field, more particularly to a kind of closed mining heating cable fixes dress
Put.
Background technology
Solve hypotonic drainage from coal seam problem under mine is to increase gas permeability of coal seam at all, but the coal seam of China more than 50%
Do not possess protective layer Depressurized mining condition, this considerably increases the difficulty that coal seam is anti-reflection；Prior art is in order to solve low-permeable
Technical sophistication that coal seam is anti-reflection, coal seam is heated by heating cable to increase gas permeability of coal seam.Because digging distance in colliery is longer, add
The hot time is longer, and heating cable is directly arranged in drilling, easily cause heating cable surface insulation shelling damage, bending, fold,
Surface contamination is difficult to clean.Run into the brill that collapses and easily cause heating cable and fracture, cause heating cable short-circuit, potential safety hazard be present,
Influence the efficiency of heating surface.
Utility model content：
The technical problems to be solved in the utility model：A kind of closed mining heating cable fixing device is provided, to solve
Prior art solves the anti-reflection technical sophistication of low air permeability coal seam, heats coal seam by heating cable to increase gas permeability of coal seam.By
Longer in colliery digging distance, the heat time is longer, and heating cable is directly arranged in drilling, easily causes heating cable surface
Insulated hull abrasion, bending, folding, surface contamination are difficult to clean.Run into the brill that collapses and easily cause heating cable and fracture, cause heating electric
, potential safety hazard be present, influence the technical problems such as the efficiency of heating surface in cable short circuit.
Technical solutions of the utility model：
A kind of closed mining heating cable fixing device, it includes two symmetrical semicircular shells, and two symmetrical
Fixed body is respectively arranged with semicircular shell, opens up fluted, the groove pair on two fixed bodies on two fixed bodies respectively
Claim to set；Two symmetrical semicircular shells are bolted one oval-shaped shell of composition.
The quantity of groove is more than one group.
Sealing gasket is provided with fixed body.
Semicircular shell is stretched out at the width both ends of fixed body respectively, and the width both ends of fixed body pass through spiral shell respectively
Screw bolt and nut is fixedly connected.
Two symmetrical semicircular shell length are 1.2-1.5 rice；Material is that light metal alloys or thermal conductivity are good
Non-metallic material.
Fixed body both ends and centre position are fixed by screw bolt and nut.
Two adjacent groups half elliptic housing is connected by the attachment spacers on fixed body.
A kind of fixing means of described closed mining heating cable fixing device, it includes：
Step 1, heating cable is fixed in the groove on fixed body；
Step 2, the fixed body on two symmetrical semicircular shells is fixedly connected by bolt and nut, forms a circle
Shape housing；
Step 3, two adjacent groups half elliptic housing connected by attachment spacers, extended.
The beneficial effects of the utility model：
Heating cable is enclosed in the groove of oval-shaped shell by the utility model, then whole device is put into drilling
Portion, and directly contacted with drill hole inner wall against drill hole inner wall；It can effectively avoid heating cable frictional dissipation, heating cable bending short
Road and heating cable surface contamination are difficult to clean, and improve the efficiency of heating surface and job security；Using the utility model heating cable
Fixing device, heating cable frictional dissipation, heating cable bending short circuit and heating cable surface contamination can be effectively avoided to be difficult to clearly
Wash, improve the efficiency of heating surface and job security；Solve prior art heating cable fixing device to be directly arranged in drilling, it is close
Envelope property it is poor, easily cause heating cable surface pollution be difficult to clean, run into brills that collapse, drilling in coal petrography extrude easily cause heating electric
Cable fractures, and causes heating cable short-circuit, potential safety hazard be present, influence the technical problems such as the efficiency of heating surface.
