Abstract

The invention discloses an S-shaped pipe valve for a mining shotcrete machine and a connection assembly thereof. The S-shaped pipe valve comprises an adjustable flange (3) and an adjustment gasket (15), wherein the adjustable flange (3) is connected with a transparent cover I (6) through a bolt after being welded with a discharged concrete receiving pipe (2), and the adjustment gasket is arranged between a hopper rear wall (1-2) and a bearing chamber II (10). An S-shaped pipe valve body (5-1) of an S-shaped pipe valve assembly and a pivot shaft (5-4) are cast integrally. A wear-resisting plate (5-3) of the S-shaped pipe valve assembly is welded with a guide pipe (5-2) and then installed and welded onto the S-shaped pipe valve body, and the guide pipe is in a shape of a parabola with an upward opening. By additionally arranging the adjustment gasket between the hopper rear wall and the bearing chamber II and matching the adjustment gasket with the adjustable flange, a reasonable gap between the wear-resisting plate on the S-shaped pipe valve assembly and a concrete conveying cylinder wear plate is kept all the time, and sparks generated by friction are avoided. The wear-resisting plate is welded with the guide pipe and then installed and welded to the S-shaped pipe valve body, so that working efficiency of the mining shotcrete machine is increased.

Description

A kind of concrete for mines spraying machine S shape pipe valve and coupling assembling thereof

Technical field

The present invention 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, the concrete wet spraying machine conveying principle of down-hole adopts on ground the very ripe pump technology of dragging more, but in use there are the following problems for technique:

1) in the time carrying out concrete conveyance operation, S shape pipe valve is wanted the cheater plate friction on moment and hopper rear wall, the normal way adopting is to be provided with rubber spring in the end of S shape pipe valve at present, by wearing plate is connected with rubber spring, under the effect of rubber spring, make together with wearing plate abuts against with cheater plate, but in the time of 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 under coal mine;

2) because concrete needs conversion pathway in entering concrete cylinder, in concrete piston cylinder, be full of all the time concrete if make, just require concrete to have the enough large slump, once be low slump concrete in hopper, concrete is difficult to fast concrete cylinder is full of 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 form air duct, by air inspiration concrete cylinder, reduce concrete transfer efficiency.

Summary of the invention

The invention 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, ensure the safety in production under coal mine; S pipe valve assembly adopts gravity guidance mode that a large amount of concrete are imported in concrete cylinder smoothly, effectively improves concrete ejection efficiency under coal mine, thereby 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, after welding is taken in described adjustable flanges and concrete discharging and transparent cover I be bolted, and with nut check, adjusting 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 and mozzle weld rear and S pipe valve assembly welding; Described mozzle comprises left mozzle and right mozzle, and the two formation is 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, by increasing and regulate pad and coordinate adjustable flanges between hopper rear wall and bearing chamber II, by placing suitable adjusting pad quantity, then regulate the axial displacement of adjustable flanges, wearing plate and concrete conveying cylinder cheater plate on S pipe valve assembly remain rational gap, have avoided, because pyrophoric phenomenon is produced in the two friction, having met environmental requirement under coal mine; Wearing plate and mozzle weld rear and S pipe valve assembly welding, because mozzle is parabolic shape and opening up, in the time that S pipe valve commutates, can make low slump concrete flow into smoothly concrete cylinder piston rod, prevent that in concrete cylinder piston rod and S shape pipe valve, concrete is interrupted importing interruption, avoid forming air duct, thereby improved the operating efficiency of concrete for mines wet spraying machine.

Detailed description of the invention

Below in conjunction with accompanying drawing, the present invention is further described.

As shown in Fig. 1,2,3 and 4, this concrete for mines spraying machine S shape pipe valve and coupling assembling thereof, comprise 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, the S pipe valve 5-1 of 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 bolted with transparent cover I 6 after taking over 2 welding with concrete discharging, and locks with nut 4, and adjusting pad 15 is 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 and mozzle 5-2 weld rear and S pipe valve 5-1 assembly welding; Described mozzle 5-2 comprises left mozzle 5-2.1 and right mozzle 5-2.2, and the two formation is opening up parabolic shape.
