Abstract
The utility model discloses a gripper of a horizontal position drilling machine, which comprises a fixed gripper body (9), a turnover gripper body (7) and a turnover oil cylinder (2), wherein the fixed gripper body (9) and the turnover gripper (7) are respectively provided with a position oil cylinder (3) and gripping oil cylinder (5) which are on the same gripping axis and are oppositely arranged, and the gripping axes of the fixed gripper body (9) and the turnover gripper body (7) are downwards inclined to one side of the turnover oil cylinder (2). The utility model provides the gripper of the horizontal position drilling machine, which has high effect of disassembling and assembling buttons, accurate position, simple structure and reliable property.
Description
Technical field
The utility model relates to a kind of clamper, particularly relates to a kind of horizontal directional drilling machine clamper.
Background technology
Clamper is the parts of the loading and unloading drilling rod of horizontal directional drilling machine, is characterized in the operating frequency height, requires accurate positioning.Clamper structure such as Fig. 1 and Fig. 2 of present domestic most horizontal directional drilling machine producer, when being screwed into a drilling rod, overturn before this oil cylinder rodless cavity oil-feed in the cramping body, piston rod stretches out, promote the fixture block assembly and clamp the public silk end of this drilling rod, utilize the unit head rotation torque to screw in female silk end of drilling rod again, overturn then cylinder rod chamber oil-feed in the cramping body, the piston rod withdrawal, the fixture block assembly unclamps, the oil cylinder rodless cavity oil-feed in the fixed clamp body, piston rod stretches out, promote the fixture block assembly and clamp the female silk end of another root drilling rod, unit head advances simultaneously, rotation screws in the female silk end of drilling rod that the fixed clamp body clamps with the public silk end of the drilling rod of front; When drilling rod of dismounting, unit head retreated the public silk end of this drilling rod was retreated to movable clamper before this, and clamp the public silk end of this drilling rod by upset cramping body oil cylinder, and clamp the female silk end of another drilling rod that links to each other with the palpus dismounting drilling rod by fixed clamp body oil cylinder, overturning oil cylinder rodless cavity oil-feed then, piston rod stretches out, the upset cramping body upwards overturns, and (interstitial hole with the fixed clamp body is the center, before installing on the upset cramping body, back centring ring cooperates with interstitial hole) thus unscrew the drilling rod that the upset cramping body clamps, and then the overturn cylinder rod chamber oil-feed of cramping body, unclamp drilling rod, drive the drilling rod screw thread by the unit head rotation and all unclamp.After two drilling rod ends unclamped, the upset cramping body clamped drilling rod again, utilized the unit head rotation torque to screw out the other end of palpus dismounting drilling rod.
In sum, clamper just requires accurate positioning, is swift in motion, good reliability.And in real work, because the resistance of oil cylinder itself is different, the distance of oil pipe and flowed friction are also inequality, thereby cause piston rod to stretch out inconsistent drilling rod and the unit head center decentraction that causes clamping of speed, perhaps two drilling rod male and female screw thread decentraction often cause screw thread not twist or the phenomenon of screw thread serious wear.And because the axis horizontal of cramping body is placed, the shortcoming one of existence is that operator's sight line is bad, can not see the situation in the drilling rod cargo handling process at any time clearly; The 2nd, the turnover angle of upset cramping body is little, makes the loading and unloading button efficient of clamper not high.
The utility model content
Technical problem to be solved in the utility model provides a kind of high horizontal directional drilling machine clamper of button efficient that loads and unloads.
In order to solve the problems of the technologies described above, the horizontal directional drilling machine clamper that the utility model provides, comprise fixed clamp body and upset cramping body and overturning oil cylinder, described fixed clamp body and upset cramping body are equipped with and are in a positional cylinder and clamping oil cylinder that is oppositely arranged on the same clamping axis, the positional cylinder that is oppositely arranged is connected with hydraulic pump by reversal valve with the clamping oil cylinder, described overturning oil cylinder one side direction of the clamp axis alignment setting that has a down dip of described fixed clamp body and upset cramping body.
The clamping axis of described fixed clamp body and upset cramping body and the angle [alpha] that horizontal plane is obliquely installed are 5～20 °.
Adopt the horizontal directional drilling machine clamper of technique scheme, because the clamping axis and the horizontal plane of fixed clamp body and upset cramping body are obliquely installed, 2 benefits are arranged: the one, can make operator's sight line better, can see the situation in the drilling rod cargo handling process at any time clearly; The 2nd, under the situation that does not increase the distance on plane on drilling rod center and the crossbeam, the upset turnover angle of cramping body bigger (2 α), thus make the loading and unloading button efficient of clamper higher.
In sum, the utility model is a kind of button efficient height, clamper accurate positioning and horizontal directional drilling machine clamper simple in structure, dependable performance of loading and unloading.
Description of drawings
Fig. 1 is that original clamper structure master looks schematic diagram;
Fig. 2 is that schematic diagram is looked on original clamper structure left side;
Fig. 3 is that the utility model structure master looks schematic diagram;
Fig. 4 is that schematic diagram is looked on the utility model structure left side.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 3 and Fig. 4, overturning oil cylinder 2 one end free bearings 10 are hinged, the other end is hinged with upset cramping body 7, fixed clamp body 9 and upset cramping body 7 are equipped with and are in a positional cylinder 3 and clamping oil cylinder 5 that is oppositely arranged on the same clamping axis, positional cylinder 3 is installed on fixed clamp body 9 or the upset cramping body 7 by bearing pin and baffle plate 1, prelocalization circle 6 that is equipped with on the upset cramping body 7 and back centring ring 8, settings that have a down dip of clamp axis alignment overturning oil cylinder 2 one side direction of fixed clamp body 9 and upset cramping body 7, fixed clamp body 9 and overturn the clamping axis of cramping body 7 and the angle [alpha] that horizontal plane is obliquely installed are 5～20 °.
Referring to Fig. 3 and Fig. 4, the setting because clamp axis alignment overturning oil cylinder 2 one side direction of fixed clamp body 9 and upset cramping body 7 have a down dip, the clamping axis of fixed clamp body 9 and upset cramping body 7 and the angle [alpha] that horizontal plane is obliquely installed are 5～20 °, 2 benefits are arranged: the one, can make operator's sight line better, at any time can see the situation in drilling rod 11 cargo handling processes clearly, A is a direction of visual lines among Fig. 3; The 2nd, under the situation that does not increase the distance on plane on drilling rod 11 centers and the crossbeam, upset cramping body 7 turnover angles bigger (2 α=10～40 °), thus make the loading and unloading button efficient of clamper higher.
