Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of adjusting pressure assembly, according to the pressure condition of roadway surrounding rock, can allow in time and press or supercharging.
To achieve these goals, a kind of adjusting pressure assembly of the present invention, comprise its interior piston, pressure sensor, tumbler and stretch board of oil cylinder, oil cylinder both sides arrange respectively otic placode, in otic placode, offer the fixedly bellmouth of steel hinge line, pressure sensor is arranged on the front end of oil cylinder through piston, and tumbler is arranged on piston, in the front portion of pressure sensor, stretch board is positioned at the end of piston, offers the fixedly bellmouth of steel hinge line on stretch board.
Further, tumbler comprises screw rod, screw thread, bearing, handle, brake(-holder) block and stops bar, on a base inner surface, a plurality of prevention bars is set, bearing screw rod is axially set, screw thread is set on screw rod, the arranged outside brake(-holder) block of screw rod, the end of screw rod is connected with handle.
Further, pressure sensor is piezoelectric transducer.
Compared with prior art, according to the actual condition of roadway surrounding rock, when anchor cable needs supercharging, by swinging handle, carry out adjustable brake sheet, deasil rotary handle, drives the screw thread on screw rod to be rotated counterclockwise, steel hinge line, away from the direction motion of stretch board, makes anchor cable supercharging; When anchor cable need to allow pressure, by swinging handle, carry out adjustable brake sheet, rotate in the counterclockwise handle, drive the screw thread on screw rod to turn clockwise, make steel hinge line towards the direction motion of stretch board, make anchor cable allow pressure, after repressurize.Compared with prior art, this adjusting pressure assembly can allow press again can supercharging, and to reducing roof fall and deformation of the surrounding rock in tunnel, subside etc., disaster is of great importance.It is simple in structure, easy to use, practical.

The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As depicted in figs. 1 and 2, a kind of adjusting pressure assembly of the present invention, comprise oil cylinder 1 and interior piston 2, pressure sensor 4, tumbler 5 and stretch board 6 thereof, oil cylinder 1 both sides arrange respectively otic placode 3, in otic placode 3, offer the fixedly bellmouth of steel hinge line, pressure sensor 4 is arranged on the front end of oil cylinder 1 through piston, and tumbler 5 is arranged on piston 2, in the front portion of pressure sensor 4, stretch board 6 is positioned at the end of piston 2, offers the fixedly bellmouth of steel hinge line on stretch board 6.
Further this enters in the present invention, as shown in Figure 3, tumbler 5 comprises screw rod 51, screw thread 52, bearing 53, handle 54, brake(-holder) block 55 and stops bar 56, a plurality of prevention bars 56 are set on bearing 53 inner surfaces, bearing 53 screw rod 51 is axially set, on screw rod 51, screw thread is set, the arranged outside brake(-holder) block 55 of screw rod 51, the end of screw rod 51 is connected with handle 54.
Adjusting pressure assembly of the present invention, is best suited in anchor beam rete cord Combined Support Technology and according to the actual pressure size in roadway surrounding rock region, anchor cable is allowed and pressed or supercharging, in this pressure assembly, can have the steel hinge line in multiple directions.
Operating principle; According to the actual pressure situation of roadway surrounding rock, when anchor cable needs supercharging, by swinging handle 54, carry out the state of adjustable brake sheet 55, deasil rotary handle 54, drive the screw thread 52 on screw rod 51 to be rotated counterclockwise, make steel hinge line away from the direction motion of stretch board 6; When anchor cable need to allow pressure, by swinging handle 54, carry out the state of adjustable brake sheet 55, rotate in the counterclockwise handle 54, drive the screw thread 52 on screw rod 51 to turn clockwise, make steel hinge line towards the direction motion of stretch board 6, after allowing and pressing, repressurize.
Embodiment:
In this adjusting pressure assembly, have four steel hinge lines, two steel hinge lines on otic placode 3 are motionless, by adjusting steel hinge line on stretch board 6, give to allow with it, press or supercharging.First pressure sensor 4 is preset to maximum pressure value N1 and minimum pressure values N2, the force value that tunnel detected when pressure sensor 4 is greater than N1, can send warning, because steel hinge line continues in this state, can cause roof fall disaster, operating personnel's swinging handle, make brake(-holder) block 55 in the state shown in Fig. 5, rotate in the counterclockwise ground handle 54, drive the screw thread 52 on screw rod 51 to turn clockwise simultaneously, make steel hinge line to the direction motion of stretch board 6, the steel strand on this stretch board 6 are in allowing pressure condition; Owing to stoping the effect of bar 56, rotary handle clockwise direction can not move.After allowing and pressing, operating personnel's swinging handle 54, make brake(-holder) block 55 in the state shown in Fig. 4, deasil rotary handle 54, drive the screw thread 52 on screw rod 51 to be rotated counterclockwise simultaneously, make steel strand away from the direction motion of stretch board 6, the steel hinge line on this stretch board 6 is in pressurized state, the pressure of supercharging is not less than N2, can control by pressure sensor 4.
Under the extruding force effect in roadway surrounding rock region, the pressure that anchor cable bears is reducing, and its value is less than N2, and pressure sensor 4 can send warning, if give not in time anchor cable supercharging, also can cause failure of cable, makes roadway surrounding rock occur large deformation and is caving.Operating personnel's swinging handle 54 makes brake(-holder) block 55 in the state shown in Fig. 4, handle 54 turns clockwise, drive the screw thread 52 on screw rod 51 to be rotated counterclockwise, make steel hinge line away from the direction motion of stretch board 6, steel strand on this stretch board 6 are in pressurized state, the pressure of supercharging is not more than N1, by pressure sensor 4, controls its pressure size.
The pressure sensor 4 that the present invention adopts can be piezoelectric transducer, and it has highly sensitive, simple in structure, lightweight, is particularly suitable for the engine request on mine.
