Description

Orifice Fixing Device for Capsule Sealing Fluid Pressure Measurement Equipment

technical field

The utility model relates to an orifice fixing device used for pressure measuring equipment for capsule sealing fluid, which belongs to the field of coal mine safety. the

Background technique

Capsule sealing fluid pressure measurement equipment is currently the most widely used coal seam gas pressure measurement device with the highest pressure measurement success rate. When this device measures coal seam gas pressure, especially when drilling at a large angle, capsules may rush out and capsules may fall, etc. ACCIDENT. the

Utility model content

In order to prevent the occurrence of the above-mentioned accidents, the utility model proposes an orifice fixing device for the pressure measuring equipment of the capsule sealing liquid. , to ensure that the hole sealer will not move relatively to the borehole during the pressure measurement stage, and improve the safety of the gas pressure measurement work. the

The utility model is achieved through the following technical solutions: the orifice fixing device used for capsule sealing liquid pressure measuring equipment includes an annular tie hoop that can be movably connected with the four branch pipes of the hole sealing device; one side of the tie hoop is open And connected by bolt two; the other side of the tie is connected with a fixing piece with a screw hole, and a bolt one is screwed inside the fixing piece with a screw hole, and the bottom end of the bolt one is connected with a shaft sleeve; Both sides of the fixing part with screw holes are respectively hinged with X-shaped movable feet, and the bottom ends of the X-shaped movable feet are hinged with the shaft sleeve. the

The X-shaped movable foot is formed by hinges of two rod bodies, and its outer end is provided with a sharp angle, which can be inserted into the wall of the pressure-measuring borehole and fixed with the pressure-measuring borehole. the

The beneficial effects of the utility model are: the orifice fixing device used for the capsule sealing fluid pressure measurement equipment can ensure that the hole sealer will not move relatively to the borehole during the pressure measurement stage, which improves the safety of the gas pressure measurement work sex. the

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described. the

Accompanying drawing 1 is the structural diagram of the opening state of the orifice fixing device used in the capsule sealing liquid pressure measuring equipment. the

Accompanying drawing 2 is the side view of the orifice fixing device used in the capsule sealing fluid pressure measuring equipment. the

Accompanying drawing 3 is the structural diagram of the closing state of the orifice fixing device used for the capsule sealing liquid pressure measuring equipment. the

In the figure, 1. Bolt 1, 2. Quarter pipe, 3. Tie hoop, 4. Fixing piece with screw holes, 5. X-shaped movable foot, 6. Bushing, 7. Pressure measuring drilling, 8. Bolt 2 . the

Detailed ways

As can be seen from the accompanying drawings, the orifice fixing device used for capsule sealing liquid pressure measuring equipment includes an annular tie 3 that can be flexibly connected to the quadrant pipe 2 of the hole sealer; one side of the tie 3 is open and Connected by bolt two 8; the other side of the clamp 3 is connected with a fixing piece 4 with a screw hole, and a bolt one 1 is screwed inside the fixing piece 4 with a screw hole, and the bottom end of the bolt one 1 is connected with Axle sleeve 6 ; X-shaped movable feet 5 are respectively hinged on both sides of the fixed member 4 with screw holes, and the bottom end of the X-shaped movable foot 5 is hinged with the axle sleeve 6 . the

The X-shaped movable foot 5 is hinged by two rod bodies, and its outer end is provided with a sharp angle, which can be inserted into the wall of the pressure measurement borehole 7 and fixed with the pressure measurement borehole 7 . the

After completing the installation of the hole sealer, the orifice fixing device described in the utility model is fixed on the four-point pipe 2 at the orifice of the pressure measuring borehole 7 through the tie hoop 3, and the bolt two 8 is tightened to ensure that the orifice The fixing device does not move relative to the four branch pipe 2. It can be seen from the accompanying drawing 3 that the orifice fixing device is closed at this time, and then the bolt 1 is tightened so that the X-shaped movable foot 5 bears against the wall of the pressure measuring hole 7 ( See attached drawing 1), when accidents such as capsule rushing out or capsule dropping occur in the hole sealer, the X-type movable feet 5 can ensure that the hole sealer does not move relatively relatively to the pressure measuring hole 7, and prevent accidents from causing large losses . the
