Abstract
The invention relates to an oil cylinder counter-supporting type reinforced gripper. A normally-opened gripper used as a common hydraulic gripper generally requires larger oil cylinders or higher system pressure and is hard to open when spring force is under level. The oil cylinder counter-supporting type reinforced gripper provided is a normally-opened hydraulic gripper which is high in clamping force, small in outline size and simple in structure. Reinforcing devices are bilaterally symmetrically arranged, and upper slip seats and lower slip seats are arranged on the left and the right of the gripper respectively and are hinged through pin positioning shafts which are fixed in a casing. Dowel bars are respectively arranged between the four slip seats and two pistons, balls are respectively arranged at two ends of the dowel bars, and ball sockets are arranged on the slip seats and the pistons. The oil cylinder counter-supporting type reinforced gripper can convert clamping force of a small oil cylinder into large clamping force and can effectively guarantee clamping reliability of a drilling rod.
Description
Technical field
But the present invention 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 clamp, oil cylinder and unclamps.In order to guarantee that clamper can produce large clamping force and larger opening amount, usually to select the spring of larger specification and more number to consist of.Simultaneously, in order to open reliably clamper, also need to configure larger oil cylinder, to produce the cylinder thrust greater than butterfly spring tension force.So just make the holder structure size larger, it is used at underground drill rig be subject to certain restriction.
Clamper open in usual mostly is by oil cylinder clamping, spring and unclamps.In order to guarantee that clamper can produce larger clamping force, larger 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 occur, and makes clamper open difficulty.This just requires, and guarantees in a certain size the situation of oil cylinder force-increasing mechanism to be set, and opens hard problem to solve clamper.Single oil cylinder also has use to top scissors reinforced gripping device, but this class clamper exists opening degree little, the large deficiency that waits of physical dimension, and discomfort is used at underground drill rig.
Summary of the invention
It is large that technical problem solved by the invention 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 present invention takes:
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 slip spider setting up and down, 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-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 invention has the beneficial effects as follows:
The dowel bar of this clamper, ball, slip spider and latch locating shaft have formed a cover step-up system.By this step-up system, can be converted into larger clamping force to the clamping force that small oil tank produces, can effectively guarantee the reliability of drill-rod clamping.

The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
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 slip spider 5 setting up and down, 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-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.
Oil cylinder 10 links to each other with overhead gage 1, lower baffle plate 11, front apron 15 and backboard 12 by screw.
