Description
Technical Field
The utility model relates to the technical field of coal mine operation, in particular to a coal mine drill rod fixer.
Background
Currently, the drilling machines used in underground coal mines comprise a mechanical drilling machine, a hydraulic drilling machine and a pneumatic drilling machine. Compared with other types of drilling machines, the ZQJC-380/8.0 type and ZQJC-800/11.3S type pneumatic column-type drilling machine has the advantages of light weight, simple structure and convenience in maintenance, is practical equipment in underground drilling operation of coal mines in China at present, and is widely used. The drilling machine uses compressed air as power, and can use a high-efficiency spiral drill rod to perform drilling operation. However, the construction of the column-type drilling machine in the roadway has the phenomenon of affecting the normal passing of the monorail crane and the skip car, at the moment, all drill rods in the drill hole have to be pulled out, or the drill rods are unlocked from the hole opening, so that the drill rods slide out of the drill hole to hurt people or fall into the hole depth completely,
the prior patent application with the application number of CN201310574268.1 discloses a drill rod cushion fork, which comprises a U-shaped fork head, wherein the rear end of the U-shaped fork head is provided with a long handle, a connecting part is arranged between the U-shaped fork head and the long handle, a handle is arranged on the connecting part, the outer diameter of the connecting part is larger than that of the long handle, and the height of the connecting part is the same as that of the U-shaped fork head; the drill rod fork is convenient to take, carry and assemble and disassemble, but sometimes the force is too large when the drill rod is screwed and disassembled, and the constructor is stressed too much when holding the handle, so that the fork is inclined and can not fix the drill rod, the drill rod falls off from the U-shaped fork opening, and the drilling tool falls into the hole to cause an accident in the hole, thereby being heavy in tragic.
Disclosure of Invention
The present utility model aims to solve the above problems, and thus provides a coal mine drill rod holder capable of securing a drill rod.
The utility model solves the problems, and adopts the following technical scheme:
the utility model provides a colliery drilling rod fixer, includes the ring flange, parallel fixation has two bracing pieces on the ring flange top surface, and two bracing pieces use the ring flange centre of a circle to set up and all are located ring flange access way top as central point symmetry, and the top of two bracing pieces is provided with solid fixed ring jointly.
Compared with the prior art, the utility model adopting the technical scheme has the outstanding characteristics that:
the flange plate is fixedly connected with the orifice pipe through the bolts, the cushion fork is horizontally inserted between the flange plate and the fixed ring along the two support rods, the cushion fork is inserted along the bayonet of the drill rod when the cushion fork is limited all around, the drill rod is fixed by the fixer while the cushion fork is fixed, and the drill rod can be unlocked by operating the drilling machine when the cushion fork is clamped firmly, so that the drill rod remained in the hole can be effectively prevented from loosening, sliding out and damaging people and falling into the hole.
Preferably, the utility model further adopts the technical scheme that:
the circle centers of the fixed ring and the flange plate are opposite.
The diameters of the circular holes in the middle of the fixed ring and the passage opening of the flange are both larger than the diameter of the drill rod.
The distance between the two support rods is matched with the width of the cushion fork, and the distance between the flange plate and the fixing ring is matched with the thickness of the cushion fork.

FIG. 2 is a schematic diagram of a front view structure of an embodiment of the present utility model;
FIG. 3 is a schematic diagram of a fork structure used in an embodiment of the present utility model;
marked in the figure as: flange 1, bracing piece 2, solid fixed ring 3, pad fork 4.
Description of the embodiments
The utility model is further described below in connection with the following examples which are provided for the purpose of better understanding of the present utility model and are, therefore, not to be construed as limiting the scope of the utility model.
The utility model provides a colliery drilling rod fixer, includes ring flange 1, and parallel fixation has two bracing pieces 2 on the ring flange 1 top surface, and bracing piece 2 adopts the thick steel bar preparation, and 2 horizontal welding of bracing piece are on ring flange 1 top surface, and two bracing pieces 2 use ring flange 1 centre of a circle as central point symmetry setting and all are located ring flange 1 access opening top, and the top of two bracing pieces 2 is provided with solid fixed ring 3 jointly, gu fixed ring 3 horizontal welding is on bracing piece 2.
The circle centers of the fixed ring 3 and the flange plate 1 are opposite, so that dislocation after penetration of the drill rod is prevented.
The diameters of the middle round hole of the fixed ring 3 and the passage opening of the flange plate 1 are both larger than the diameter of the drill rod, and the diameter of the middle round hole of the fixed ring 3 is smaller than the diameter of the passage opening of the flange plate 1.
The interval of two bracing pieces 2 and cushion fork 4 width looks adaptation, the interval of ring flange 1 and solid fixed ring 3 and cushion fork 4 thickness looks adaptation, and is spacing about the upper and lower of cushion fork 4, prevents that cushion fork 4 from taking place the slope.
The flange plate is fixedly connected with the orifice pipe through the bolts, the cushion fork is horizontally inserted between the flange plate and the fixed ring along the two support rods, the cushion fork is inserted along the drill rod bayonet when the cushion fork is limited all around, the drill rod is fixed by the fixer while the cushion fork is clamped firmly, and the drill rod can be unlocked by the operating drill machine, so that the drill rod remained in the hole can be effectively prevented from slipping out to hurt people and falling into the hole, the safety of drilling work is improved, the accident of the drill rod slipping out to hurt people can be effectively avoided, the cost is greatly reduced, and the time is saved.
The foregoing description of the preferred embodiments of the utility model is not intended to limit the scope of the claims, but rather to cover all equivalent modifications within the scope of the present utility model as defined by the appended claims.
