Abstract
The utility model discloses a underground hydraulic punching device with a range being extended, and relates to a high pressure water device, in particular to a hydraulic punching device with a range being extended for hydraulic slotting in a tunnel underground a coal mine. The device comprises a water inlet hose connected with a water inlet pipe, wherein an operation board is arranged at a water inlet of the water inlet pipe; the water inlet pipe is connected with an extension pipe joint; the extension pipe joint is connected with one end of a telescopic sleeve; the other end of the telescopic sleeve is connected with a sleeve of a water outlet pipe; a telescopic bracket is welded at the middle part of the water inlet pipe for supporting; the bottom of the telescopic bracket is welded with a base; the bottom of the base is welded with back-double-brake universal wheels; a seal ring is mounted at a water outlet of the water outlet pipe and connected with a cone-shaped nozzle by a tight nut; and an end cylindrical cavity is arranged at the front of the cone-shaped nozzle. The device is scientific and reasonable in structure, can slot a deeper slotted hole, effectively releases gas, avoids extrusion, and has the characteristics of deepness in slotting, convenience in operation, safety, reliability and the like.
Description
Technical field
The utility model relates to a kind of high-pressure water device, particularly a kind of colliery underworkings waterpower slotting hydraulic flushing in hole device that prolongs range.
Background technology
Remain a kind of outburst prevention measures of colliery underworkings speedy drivage at present in China's waterpower slotting, be to arrange the high pressure water injection device at digging laneway, utilize water under high pressure that work plane the place ahead coal body is washed away, form the groove hole of certain depth and sectional area, thereby reach the purpose that gas discharges pressure-relief outburst-prevention.Hydraulic flushing in hole is mainly realized by giant, and utilize the water under high pressure of booster pump pressurization to penetrate through giant by high-pressure water pipeline, and the degree of depth that facts have proved the waterpower easer is more dark, the drawing-off gas effect in its deep is more good, after but devices such as booster pump and giant are connected and fixed at present, its water under high pressure range is also fixing, can't utilize giant to draw out required darker slotted eye.
Summary of the invention
The utility model is at the problems referred to above, aims to provide that a kind of coal mine gas protrusion-dispelling uses, and has liftable prolongation range effect hydraulic flushing in hole high-pressure installation.
Structure implementation of the present utility model is: comprise, water supply hose is connected with water inlet pipe, water inlet pipe water inlet setting operation dish, and water inlet pipe is connected with the prolongation tube coupling, prolong tube coupling and be connected with extension sleeve one end, the extension sleeve other end is connected with the sleeve of outlet pipe; The water inlet pipe middle part is welded with telescoping shoring column and supports, and the telescoping shoring column bottom is welded with base, the two very universal wheels processed in welding back, base bottom; Sealing ring is equipped with at the delivery port place of outlet pipe, is connected with conical nozzle by clamp nut, and an end cylindrical cavity is set before the conical nozzle.
The utility model utilizes the prolongation tube coupling that is connected between water inlet pipe and the outlet pipe, be implemented in the waterpower slotting process, when first time punching finishes, gas density is down to normal concentration when following, personnel enter the scene, second joint is prolonged tube coupling be connected on the outlet pipe, personnel remove safety place again, start high-pressure hydraulic pump, carry out the punching second time, can draw out darker slotted eye, discharge gas effectively, prevent from giving prominence to.Characteristics such as it is darker to have slotting, easy to operate, safe and reliable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to Fig. 1, the utility model is that water supply hose 8 is connected with water inlet pipe 1, water inlet pipe 1 water inlet setting operation dish 9, water inlet pipe 1 is connected with prolongation tube coupling 2, prolong tube coupling 2 and be connected with extension sleeve 11 1 ends, extension sleeve 11 other ends are connected with outlet pipe sleeve 3, and water inlet pipe 1 middle part is welded a telescoping shoring column 6 and supported, the telescoping shoring column bottom is welded with base 7, the two very universal wheels 10 processed in welding back, base 7 bottoms; Be equipped with sealing ring and be connected with conical nozzle 5 by clamp nut 4 at the delivery port place of outlet pipe, and an end cylindrical cavity 12 is set before the conical nozzle.Prolong tube coupling 2, extension sleeve 11, outlet pipe and conical nozzle 5 concentrics.
Before carrying out operation, prolong the quantity of tube coupling 2 according to on-the-spot slotted eye degree of depth needs, movable base 7 fixed-site universal wheels 10, where dual brake universal wheel processed can be in office guarantees the utility model balance and stability under the condition, regulate the height of telescoping shoring column 6 then, utilize water supply hose 8 high-pressure water pipe to be connected to the increase water pump of far-end, then can begin to carry out waterpower slotting operation, when the punching first time finishes, gas density is down to normal concentration when following, and personnel enter the scene, and prolongation tube couplings such as second joint or three joints are connected on the outlet pipe, personnel remove safety place again, start high-pressure hydraulic pump, carry out the punching second time, can draw out darker slotted eye, discharge gas effectively, prevent from giving prominence to.Characteristics such as it is darker to have slotting, easy to operate, safe and reliable.
