Description

Concrete for mines spraying machine S shape pipe valve and coupling assembling thereof

Technical field

The utility model relates to a kind of parts of concrete for mines spraying machine, specifically a kind of concrete for mines spraying machine S shape pipe valve and coupling assembling thereof.

Background technology

At present, very ripely on concrete wet spraying machine conveying principle many employings ground of down-hole drag pump technology, but in use there are the following problems for technique:

1) when carrying out concrete conveyance operation, S shape pipe valve wants the cheater plate friction on moment and hopper rear wall, the normal way adopted is provided with rubber spring in the end of S shape pipe valve at present, by wearing plate is connected with rubber spring, make together with wearing plate abuts against with cheater plate under the effect of rubber spring, but when delivering concrete, along with S shape pipe valve swings rapidly, friction between wearing plate and cheater plate will produce spark unavoidably, brings certain potential safety hazard to the production of underground coal mine;

2) because concrete needs conversion pathway when entering concrete cylinder, all the time concrete is full of in concrete piston cylinder if make, just require that concrete has the enough large slump, once be low slump concrete in hopper, then concrete is difficult to be full of by concrete cylinder fast at short notice, can make concrete generation disruption in concrete cylinder and S shape pipe valve, because S shape pipe valve swings rapidly in hopper, can air duct be formed, by air inspiration concrete cylinder, reduce concrete transfer efficiency.

Summary of the invention

The utility model provides a kind of concrete for mines spraying machine S shape pipe valve and coupling assembling thereof, can avoid due to S pipe valve wearing plate and the fricative pyrophoric behavio(u)r of concrete conveying cylinder cheater plate, ensures the safety in production of underground coal mine; S pipe valve assembly adopts gravity guidance mode to import in concrete cylinder smoothly by a large amount of concrete, effectively improves the concrete ejection efficiency of underground coal mine, thus improves concrete transfer efficiency.

For achieving the above object, this concrete for mines spraying machine S shape pipe valve and coupling assembling thereof comprise hopper, hopper antetheca, hopper rear wall, concrete discharging adapter, S pipe valve assembly, bearing chamber I, bearing I, bearing chamber II, bearing II and support tilt cylinder crank, and the S pipe valve of S pipe valve assembly is connected with the hopper antetheca of hopper by bearing I, bearing chamber I, transparent cover I; Pivot one end of S pipe valve assembly is connected with the hopper rear wall of hopper by bearing II, bearing chamber II, transparent cover II, and the other end is connected with support tilt cylinder crank by spline, and is bolted; Also comprise adjustable flanges and regulate pad, described adjustable flanges and concrete discharging take overs and to be welded afterwards and transparent cover I is bolted, and with nut check, adjustment pad is placed between hopper rear wall and bearing chamber II; The S pipe valve of S pipe valve assembly and pivot integrally casting; S pipe valve assembly wearing plate welds rear and S pipe valve assembly welding with mozzle; Described mozzle comprises left mozzle and right mozzle, and the two is formed in opening up parabolic shape.

Spacer plate shape is semicircle.

Compared with existing equipment, this concrete for mines spraying machine S shape pipe valve and coupling assembling thereof, regulate pad by increasing between hopper rear wall and bearing chamber II and coordinate adjustable flanges, by placing suitable adjustment pad quantity, then the axial displacement of adjustable flanges is regulated, wearing plate on S pipe valve assembly and concrete conveying cylinder cheater plate remain rational gap, avoid due to the two friction and produce pyrophoric phenomenon, meeting underground coal mine environmental requirement; Wearing plate welds rear and S pipe valve assembly welding with mozzle, due to mozzle parabolically shape and opening up, when S pipe valve commutates, low slump concrete can be made to flow into concrete cylinder piston rod smoothly, concrete in concrete cylinder piston rod and S shape pipe valve is prevented to be interrupted to import and to interrupt, avoid the formation of air duct, thus improve the operating efficiency of concrete for mines wet spraying machine.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is further illustrated.

As Fig. 1,2, shown in 3 and 4, this concrete for mines spraying machine S shape pipe valve and coupling assembling thereof, the S pipe valve 5-1 comprising hopper 1, hopper antetheca 1-1, hopper rear wall 1-2, concrete discharging adapter 2, S pipe valve assembly 5, bearing chamber I 7, bearing I 8, bearing chamber II 10, bearing II 11 and support tilt cylinder crank 13, S pipe valve assembly 5 is connected with the hopper antetheca 1-1 of hopper 1 by bearing I 8, bearing chamber I 7, transparent cover I 6; Pivot 5-4 one end of S pipe valve assembly 5 is connected with the hopper rear wall 1-2 of hopper 1 by bearing II 11, bearing chamber II 10, transparent cover II 12, and the other end is connected with support tilt cylinder crank 13 by spline 5-4.1, and is fixed by bolt 14; Also comprise adjustable flanges 3 and regulate pad 15, described adjustable flanges 3 is welded with concrete discharging adapter 2 afterwards and transparent cover I 6 is bolted, and locks with nut 4, regulates pad 15 to be placed between hopper rear wall 1-2 and bearing chamber II 10; The S pipe valve 5-1 of S pipe valve assembly 5 and pivot 5-4 integrally casting; S pipe valve assembly 5 wearing plate 5-3 welds rear and S pipe valve 5-1 assembly welding with mozzle 5-2; Described mozzle 5-2 comprises left mozzle 5-2.1 and right mozzle 5-2.2, and the two is formed in opening up parabolic shape.
