Abstract
The utility model provides a clamp used for a drilling machine capable of horizontally and directionally drilling into laid pipes. The clamp comprises a front clamp and a rear clamp; a front clamp body, a pair of holding oil cylinders and a pair of slips' bowls are mounted on the front clamp; the slips' bowls can jam a drill rod joint of the drilling machine after moving; the holding oil cylindersare fixed at two ends of the front clamp respectively; a through hole for the passing of the drill rod is formed in the front clamp body; a rear clamp body, a holding oil cylinder, a shackle oil cylinder and a moving slips' bowl and a fixed slips' bowl are mounted on the rear clamp; the moving slips' bowl and the fixed slips' bowl can tightly jam the drill rod joint of the drilling machine; the moving slips' bowl is mounted on the piston rod of the holding oil cylinder; the fixed slips' bowl is mounted on one side of the rear clamp body; and the piston rod of the shackle oil cylinder is connected with the rear clamp body. In the utility model, only one holding oil cylinder is arranged on the rear clamp of the clamp used for a drilling machine capable of horizontally and directionally drilling into laid pipes, so that the size of the rear clamp is small.
Description
[technical field]
The utility model relates to a kind of horizontal orientation and creeps into pipe laying rig clamper.
[background technology]
Horizontal orientation creeps into pipe laying rig clamper, is mainly used in the unloading drill rod thread, is the crucial building block of rig, handles frequent.The clamper commonly used pair oil cylinders that adopt make that the appearance and size of clamper is bigger more, and the shackle oil cylinder of the back clamper of clamper all is installed in the bottom, and the shackle oil cylinder is subjected to the high restriction in the center of clamper, and shackle moment is little and the shackle angle of revolution is little.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of horizontal orientation to creep into pipe laying rig clamper, and its appearance and size is little.
For solving the problems of the technologies described above, the technical solution of the utility model is: provide a kind of horizontal orientation to creep into pipe laying rig clamper, described clamper comprises front clamp device and back clamper, the slip spider that can block the borer drill rod joint after front clamp body, a pair of clamping oil cylinder and a pair of the moving is installed on the front clamp device, and the clamping oil cylinder is separately fixed at the two ends of front clamp body; The front clamp body is provided with the through hole that passes through for drilling rod; Back clamping body, a clamping oil cylinder, shackle oil cylinder, the moving slip spider that can tighten the borer drill rod joint and a quiet slip spider are installed on the back clamper, moving slip spider is installed on the piston rod of clamping oil cylinder, and quiet slip spider is installed in a side of back clamping body; The piston rod of described shackle oil cylinder connects with back clamper sports association.
Compared with prior art, above-mentioned horizontal orientation creeps on the back clamper of pipe laying rig with clamper and only is provided with a clamping oil cylinder, and appearance and size is little.
[description of drawings]
Fig. 1 is the front elevational schematic of the forward and backward clamper of the utility model one preferred embodiment tool.
Fig. 2 is the schematic side view of middle front clamp device embodiment illustrated in fig. 1.
Fig. 3 is the schematic side view of middle back embodiment illustrated in fig. 1 clamper.
Fig. 4 be along K among Fig. 3 to cross-sectional schematic.
[specific embodiment]
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clear more in order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
See also Fig. 1 to Fig. 4, be that the utility model horizontal orientation creeps into the preferred embodiment of pipe laying rig with clamper, described clamper comprises front clamp device 1 and back clamper 2 (also being the shackle clamper), and front clamp body 10, front clamp device support 11, a pair of clamping oil cylinder 12 and a pair of slip spider 14 are installed on the described front clamp device 1.Described front clamp body 10 is by being bolted on the front clamp device support 11, and described clamping oil cylinder 12 is separately fixed at the two ends of front clamp body 10, on the described slip spider 14 slips bar 16 is installed.Described front clamp body 10 is provided with through hole 18.During work, the drilling rod (not shown) is located in through hole 18 places, and the rodless cavity of two clamping oil cylinders 12 is oil supply simultaneously, and two slip spiders 14 are to through hole 18 central motions, and blocking needs the tool joint of unloading (not shown).
After front clamp device 1 and back clamper 2 are all clamped the drilling rod connection, the rodless cavity oil-feed of shackle oil cylinder 23, the piston rod of shackle oil cylinder 23 is by shackle bearing pin 27, promote back clamping body 20 and on the gripper brackets 21 of back, rotate an angle around the drilling rod center, make tool joint thread dismantle first button, both finished and dismantled the drilling rod action.After this clamping oil cylinder 22 rod chamber oil-feeds, moving slip spider 24 and quiet slip spider 25 unclamp drilling rod, the 23 rod chamber oil-feeds of shackle oil cylinder, back clamper 2 resets.
Above-mentioned horizontal orientation creeps on the back clamper 2 of pipe laying rig with clamper and only is provided with a clamping oil cylinder 22, and appearance and size is little; Described back clamper 2 is placing shackle oil cylinder 23 on the clamp bracket 21 of back under the situation that guarantees enough chucking powers, soon shackle oil unloads on 23 and puts, can not be subjected to the high restriction in center of clamper, increase shackle moment and shackle and angle of revolution, and the front and back width of clamper is less, and the slips bar 240 of the fine assurance slip spider 24 of energy is stuck in the joint area of drilling rod very soon.Shackle bearing pin 27 on the described shackle oil cylinder 23 has sliding tray, and the direction of motion of restriction shackle oil cylinder 23 makes that shackle oil cylinder 23 force-bearing situations are good, can improve application life.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
