A normally-opening clamp holder which is used as a common hydraulic clamp holder is usually provided with a large oil cylinder or uses high system pressure, elastic force is not enough, and the clamp holder cannot be opened easily. The oil cylinder abutting type clamp holder capable of increasing force is high in clamping capacity, small in appearance size and simple in structure. According to the oil cylinder abutting type clamp holder, force increasing devices are arranged symmetrically on the left and the right, slip bowls are arranged on the upper portion and the lower portion on the left and the right of the clamp holder, the slip bowls are hinged through an inserting pin locating shaft which is fixed in a shell body, force transmission rods are respectively arranged between four slip bowl groups and two piston groups, balls are respectively arranged at two ends of each force transmission rod, and ball sockets are arranged on the slip bowls and pistons. The clamp holder can convert clamping force generated by a small oil cylinder to large clamping force, and reliability of clamping of a drilling rod can be effectively guaranteed.
Description
Technical field
But the utility model relates to a kind of oil cylinder of reinforcement to top formula clamper, drilling tool in the clamping hole when creeping into near-horizontal hole for all-hydraulic drill.
Background technology
Hydraulic gripper commonly used can be divided into normally closed type and open in usual usually.
The normally closed type clamper mostly is by spring clamping, oil cylinder and unclamps.In order to guarantee that clamper can produce big clamping force and bigger opening amount, to select for use the spring of big specification and more number to constitute usually.Simultaneously, in order to open clamper reliably, also need to dispose bigger oil cylinder, to produce the cylinder thrust greater than butterfly spring tension force.So just make the clamper physical dimension bigger, it is used at underground drill rig be subjected to certain restriction.
Clamper open in usual mostly is by oil cylinder clamping, spring and unclamps.In order to guarantee that clamper can produce bigger clamping force, bigger oil cylinder to be set usually or adopt high system pressure.Because the existence of back pressure, oil cylinder is excessive, and the spring force deficiency can take place, and makes clamper open difficulty.This just requires, and guarantees under a certain size the situation of oil cylinder force-increasing mechanism to be set, and opens the problem of difficulty to solve clamper.Single oil cylinder also has use to top scissors reinforcement clamper, but this class clamper exists opening degree little, the big deficiency that waits of physical dimension, and discomfort is used at underground drill rig.
The utility model content
It is big that the technical problem that the utility model solves provides a kind of clamping ability, the hydraulic gripper open in usual that appearance and size is little, simple in structure.
For solving above-mentioned technical problem, the technical scheme that the utility model is taked:
But a kind of oil cylinder of reinforcement is to top formula clamper, and its clamper adopts the square chest structure, comprises oil cylinder, back-moving spring, dowel bar, slip spider, pull bar, pull-rod spring, location-plate; Two oil cylinders are symmetricly set on the clamper two ends, be provided with piston in the oil cylinder, slips is arranged in the slip spider, pull-rod spring is sleeved on the pull bar, back-moving spring is sleeved on the dowel bar, its special character is: respectively at the upper and lower settings slip spider, upper slips seat and lower slips seat are hinged by the latch locating shaft about described clamper, and the latch locating shaft is fixed in the housing; Between four groups of slip spiders and two groups of pistons dowel bar is set respectively, the dowel bar two ends are respectively arranged with ball, on slip spider and the piston ball-and-socket are set, and ball becomes sphere to contact with ball-and-socket type.Piston, upper slips seat, lower slips seat are realized whole location by ball and dowel bar.
Above-mentioned clamper square chest structure is made of overhead gage, lower baffle plate, front apron, backboard.
The square chest of above-mentioned clamper is arranged on the base, and the guide-track groove that is not communicated with is set on the front and rear baffle, and square chest can slide at base within the specific limits along guide-track groove.
The oil cylinder of above-mentioned clamper links to each other with overhead gage, lower baffle plate, front apron and backboard by screw.
The pull bar of above-mentioned clamper is arranged in location-plate by pilot hole and is threaded with upper slips seat, lower slips seat.Adjusting yoke is threaded into the resilience pretightning force that the degree of depth can change pull-rod spring in upper slips seat, lower slips seat.
The beneficial effects of the utility model are:
The dowel bar of this clamper, ball, slip spider and latch locating shaft have been formed a cover step-up system.By this step-up system, can be converted into bigger clamping force to the clamping force that small oil tank produces, can effectively guarantee the reliability that drilling rod clamps.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, but a kind of oil cylinder of reinforcement to top formula clamper, its clamper adopts square chest structure, comprises oil cylinder 10, back-moving spring 2, dowel bar 3, slip spider 5, pull bar 7, pull-rod spring 8, location-plate 14; Two oil cylinders 10 are symmetricly set on the clamper two ends, be provided with piston 9 in the oil cylinder 10, slips 6 is arranged in the slip spider 5, pull-rod spring 8 is sleeved on the pull bar 7, back-moving spring 2 is sleeved on the dowel bar 3, respectively at upper and lower settings slip spider 5, upper slips seat and lower slips seat are hinged by latch locating shaft 13 about described clamper, and latch locating shaft 13 is fixed in the housing; Between four groups of slip spiders 5 and two groups of pistons 9, dowel bar 3 is set respectively, dowel bar 3 two ends are respectively arranged with ball 4, on slip spider 5 and the piston 9 ball-and-socket is set, ball 4 becomes sphere to contact with ball-and-socket type, and piston 9, slip spider 5 are realized whole the location by ball 4 and dowel bar 3.
Clamper square chest structure is made of overhead gage 1, lower baffle plate 11, front apron 15, backboard 12.
The clamper square chest is arranged on the base 16, and the guide-track groove 17 that is not communicated with is set on the front and rear baffle, and square chest can slide at base 16 within the specific limits along guide-track groove 17.
Operating principle of the present utility model is:
