Abstract
The utility model relates to a claw type support mechanism for a tunnel drilling rig, which comprises a hydraulic cylinder, a support arm and a support base. One end of the support arm is hinged to a body of the tunnel drilling rig, the other end of the support arm is hinged with the support base, an extending end of the piston rod of the hydraulic cylinder is hinged to a body of the support arm, the rear end of a body of the hydraulic cylinder is hinged to the body of the tunnel drilling rig, and the support base is in a claw structure. Radial size of the drilling rig is reduced, the hydraulic cylinder and the support arm are matched with each other so that support is faster and more powerful according to the lever principle, each claw support is capable of rotating independently, and the support base is wedged into ground, so that the support mechanism can adapt to roughness of the ground better, and requirements of pulling and feeding force of the drilling rig in drilling can be met.
Description
Technical field
The utility model belongs to the mining equipment field, relates to the underground drill rig supporting mechanism, especially a kind of underground drill rig pawl formula supporting mechanism.
Background technology
Digging down-hole drive is previous work necessary in the coal mine operation, and underground drill rig is the capital equipment of present most of mine operation.In the process that underground drill rig creeps in underground passage, can be subjected to the powerful drag of and rich variation powerful from the coal seam, this very easily causes rig generation overvibration, skew, so the quality of rig bracing or strutting arrangement performance directly influences the height of drilling efficiency, drilling quality and the performance of rig other technologies performance.
Existing underground drill rig bracing or strutting arrangement directly supports with hydraulic prop mostly.Hydraulic pressure supports and need not to add extra bracing or strutting arrangement on rig, utilize hydraulic drive strength big, be easy to the characteristics transmitting and dispose, by hydraulic prop rig is realized multi-point support, can construct at complicated ground; But hydraulic pressure supports and moves inconvenience, is subjected to the hydraulic prop systematic pipeline restriction under the coal mine bigger, is difficult to the effect of playing stably in place higher or that top board is softer, last top.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of underground drill rig pawl formula supporting mechanism is provided, this pawl formula supporting mechanism adopts hydraulic cylinder as driving force, by the rational articulated structure of each parts, and with ground contact surface on be provided with and grab ground structure, reach simple in structure, supporting ﹠ stablizing and can effectively be suitable for the purpose of complicated ground.
The purpose of this utility model solves by the following technical programs:
This kind underground drill rig pawl formula supporting mechanism comprises hydraulic cylinder, support arm and supporting seat, and an end of described support arm is hinged on the body of underground drill rig, the hinged supporting seat of the other end of support arm; The piston rod external part of described hydraulic cylinder is hinged on one's body the arm of described support arm, and the rear end of the cylinder block of hydraulic cylinder is hinged on the body of underground drill rig; Described supporting seat is a pawl formula structure.Described supporting seat is the equilateral triangle structure, and the triangle drift angle and the described support arm of supporting seat upper end are hinged, and the lower surface of described supporting seat is provided with the sawtooth of grabbing ground.And the articulated position of the rear end of the cylinder block of described hydraulic cylinder and the body of underground drill rig is higher than the articulated position of the body of described support arm and underground drill rig.In preferred embodiment of the present utility model, the articulated position of the piston rod external part of hydraulic cylinder and described support arm arm body is near an end of the hinged described supporting seat of support arm.
The utility model has following beneficial effect than prior art:
Relative conventional support structure in the past, the utility model has shortened the radial dimension of rig, and hydraulic cylinder cooperates support arm to make support faster strong by lever principle; And each pawl formula supporting mechanism can both independent rotation, and the supporting seat of pawl formula structure can be wedged ground, better adapts to the uneven of ground, can satisfy and work the needs that pull out with centripetal force when rig creeps into.
Description of drawings
Fig. 1 is a structural principle schematic diagram of the present utility model;
Fig. 2 is the structure chart of preferred embodiment of the present utility model;
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1, underground drill rig pawl formula supporting mechanism of the present utility model comprises hydraulic cylinder 1, support arm 2 and supporting seat 3.Wherein an end of support arm 2 is hinged on the body of underground drill rig, the hinged supporting seat 3 of the other end of support arm 2.The piston rod external part of hydraulic cylinder 1 is hinged on one's body the arm of support arm 2, and the rear end of the cylinder block of hydraulic cylinder 1 is hinged on the body 5 of underground drill rig.
In preferred embodiment of the utility model, require the articulated position of the body 5 of the rear end of the cylinder block of described hydraulic cylinder 1 and underground drill rig to be higher than the articulated position of support arm 2 and the body 5 of underground drill rig, hydraulic cylinder 1 and support arm 2 form a leg-of-mutton structure together with the body 5 of underground drill rig like this, piston rod movement by hydraulic cylinder 1, utilize lever principle, making support arm 2 is the center of circle along vertically to rotation with the pin joint on the body 5 of underground drill rig, realizes the rise of supporting seat 3 and puts down.In order to make hydraulic cylinder 1 laborsaving, require the end of the articulated position of the piston rod external part of hydraulic cylinder 1 and described support arm 2 arm bodies near support arm 2 hinged supporting seats 3.
Supporting seat 3 of the present utility model is a pawl formula structure.Shown in Figure 1 is wherein a kind of structure of the present utility model, this supporting seat 3 is the equilateral triangle structure, the triangle drift angle and the described support arm 2 of supporting seat 3 upper ends are hinged, the lower surface of supporting seat 3 is provided with the sawtooth 4 that is used to grab ground, this supporting seat 3 with serrated face can better adapt to broken terrain, make its grab ground more firm.
Referring to Fig. 2, underground drill rig pawl formula supporting mechanism of the present utility model can be separately positioned on underground drill rig body around, quantity is set does not limit, as long as guarantee that the body of rig is supported stable.Underground drill rig pawl formula supporting mechanism of the present utility model needs the cooperation of hydraulic control system, and hydraulic control system is controlled stretching out of hydraulic cylinder or regained.Hydraulic cylinder 1 promotion support arm 2 is done along the line shaft on the body 5 (pin joint) and is clockwise rotated during work, then driving pawl formula supporting seat 3 moves downward, because the amplification of lever makes the very short stroke of 3 need of oil cylinder just can make pawl formula supporting seat 3 in place fast, catches ground.The pawl formula supporting mechanism that is installed on the underground drill rig can be controlled respectively by hydraulic control system, thereby makes each pawl formula supporting mechanism require to be lowered into different height according to different ground respectively.
In sum, the utility model has improved the firm speed of base, improve effective drilling time of underground drill rig, and all supporting legs of the utility model (being underground drill rig pawl formula supporting mechanism) can control independently, make rig being more prone in the firm change of complicated ground.
