Abstract
The utility model relates to a drill-rod hydraulic clamper for coal mine, comprising a left clamping device and a right clamping device, characterized in that: the left clamping device comprises a left oil cylinder body (1), a left oil cylinder piston (2), a large positioning sleeve (4), a sleeve (5), a disk spring (6), a top axle (7), a small positioning sleeve (8), a left spider seat (15) and a left spider (16); the right clamping device comprises a top pillar (10), a right oil cylinder body (11), a right oil cylinder piston (12), a right spider seat (13) and a right spider (14); the blind hole is arranged on the left spider seat (15) at the position corresponding with the top pillar (10), the spring is arranged in the blind hole; the left oil cylinder body (1), the left spider seat (15), the right spider seat (13) and the right oil cylinder body (11) are connected and locked by long bolts (3). The drill-rod hydraulic clamper for coal mine has features of simple structure, small volume, convenient opening, flexible use, no limit in the relative small situation and wide application range.
Description
(1) technical field
The utility model relates to a kind of colliery drilling rod hydraulic gripper.Be mainly used on the all-hydraulic drill with interlock function drilling tool in the clamping hole.
(2) background technology
Colliery at present commonly used can be divided into normally closed type and two kinds open in usual with the drilling rod hydraulic gripper by the state of its slips when working.
The normally closed type clamper unclamps by spring clamping, oil cylinder, the size of its clamping force depends on the tension force that spring produces, for guaranteeing enough clamping forces, need big specification or more spring, need further compression spring when unclamping clamper, need to be equipped with the oil cylinder of big section successively or improve opening pressure to produce bigger thrust.The clamper of this kind structure, volume is bigger, and opening pressure is bigger, and efficient is low.
Clamper open in usual two ends all clamp with oil cylinder, and spring unclamps, and it is more simple in structure than the normally closed type, but open the both sides slips of clamper and the external force that slip spider need be bigger, and the lateral length of clamper is longer, and less occasion is used and is restricted in the space.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide a kind of simple in structure, volume is little, open conveniently, use colliery drilling rod hydraulic gripper flexibly.
The purpose of this utility model is achieved in that a kind of colliery drilling rod hydraulic gripper, comprise left clamping device and right clamping device, it is characterized in that: described left clamping device comprises left cylinder block, left oil cylinder piston, big positioning sleeve, sleeve, disk spring, apical axis, little positioning sleeve, left slip spider and left slips; Described left oil cylinder piston is arranged in the left cylinder block, described left oil cylinder piston ejects end and links to each other with the apical axis left end, be set with disk spring on the described apical axis, locate with big positioning sleeve and little positioning sleeve described disk spring both sides, described disk spring is outside equipped with sleeve, described apical axis right-hand member links to each other with left slip spider, and described left slip spider is provided with left slips;
Described right clamping device comprises fore-set, right cylinder block, right oil cylinder piston, right slip spider and right slips; Described right oil cylinder piston is arranged in the right cylinder block, described right oil cylinder piston ejects end one side and is provided with right slip spider, described right slip spider is provided with right slips, and described right slip spider upper and lower laterally is provided with through hole, is provided with fore-set in the described through hole;
Be provided with blind hole with the left slip spider of described fore-set correspondence position, be provided with spring in the described blind hole, described spring matches with fore-set;
Described left cylinder block, left slip spider, right slip spider and right cylinder block all are connected by stay bolt and lock.
The utility model colliery has the following advantages with the drilling rod hydraulic gripper:
The utility model colliery drilling rod hydraulic gripper, simple in structure, volume is little, open conveniently, use flexibly, the less occasion in space is used unrestricted, applied widely.
