Abstract
The utility model discloses a kind of clamper that can slide, comprise a pedestal, the both sides of described pedestal are provided with briquetting, described briquetting is provided with a support plate, described support plate is interconnected by bearing pin and briquetting, and described pedestal is provided with telescopic oil cylinder, and the two ends of described telescopic oil cylinder are respectively arranged with the first ear seat and the second ear seat, telescopic oil cylinder is connected with support plate, and described support plate is provided with detachable clamper.Advantageous Effects of the present utility model is: clamper is movable, can move forward and backward, when changing the drilling tools such as reamer like this, fixture directly moves toward unit head direction, can allow out, carry out handling drilling tool and do not need active well to be opened greatly, is directly split into rig length scale in the original space of clamper according to guide rail.
Description
Technical field
The utility model relates to a kind of clamper, particularly relates to a kind of clamper that can slide.
Background technology
Clamper above current Wicresoft no-dig technique horizontal drill be all cannot move integrally, when making the drilling tools such as the upper and lower reamer of rig like this, to have before drilling machine clamp holder leave about 1 meter space, make at least large than rig length more than 1 meter of the active well of constructing like this, therefore waste a lot of manpower and materials, dig out the environment that more earth can destroy periphery simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of clamper that can slide, and solves the shortcoming that prior art exists.
The utility model adopts following technical scheme to realize:
A kind of clamper that can slide, it is characterized in that, comprise a pedestal, the both sides of described pedestal are provided with briquetting, and described briquetting is provided with a support plate, described support plate is interconnected by bearing pin and briquetting, described pedestal is provided with telescopic oil cylinder, the two ends of described telescopic oil cylinder are respectively arranged with the first ear seat and the second ear seat, and telescopic oil cylinder is connected with support plate, and described support plate is provided with detachable clamper.
Advantageous Effects of the present utility model is: detachable clamper is movable, can move forward and backward according to guide rail, when changing the drilling tools such as reamer like this, fixture directly moves toward unit head direction, can allow out in the original space of clamper, carry out handling drilling tool and do not need active well to open greatly, being directly split into rig length scale.

Detailed description of the invention
By below to the description of embodiment; to more contribute to public understanding the utility model; but the restriction that the specific embodiment given by applicant can't be considered as technical solutions of the utility model, any definition to parts or technical characteristic change and/or to overall structure do form and immaterial conversion all should be considered as the protection domain that the technical solution of the utility model limits.
The clamper that can slide as shown in Figure 1 to Figure 3, comprise a pedestal 1, the both sides of pedestal 1 are provided with briquetting 2, briquetting 2 is provided with a support plate 3, support plate 3 is interconnected by bearing pin 4 and briquetting 2, and pedestal 1 is provided with telescopic oil cylinder 7, the two ends of telescopic oil cylinder 7 are respectively arranged with the first ear seat 5 and the second ear seat 6, telescopic oil cylinder 7 is connected with support plate 3, support plate 3 is provided with detachable clamper 10, and support plate 3 is also provided with the first backing plate 8 and the second backing plate 9.Detachable clamper 10 is movable, can move forward and backward according to guide rail, when changing the drilling tools such as reamer like this, fixture directly moves toward unit head direction, can allow out in the original space of clamper, carry out handling drilling tool and do not need active well to open greatly, being directly split into rig length scale.Further improvement can also be made on the basis of above-described embodiment: carry out colliery creep into gas drainage under suction do hole time, gas extraction hole is mostly inclination angle boring upwards, at this moment rig should equipment be the clamper of normally closed type structure, and be that clamping drilling rod on rig needs to adopt and increases normally closed type and be the clamping force of drilling machine clamp holder or set up auxiliary oil cylinder, but clamping force increase can cause the physical dimension of normally closed type clamper to increase severely, hydraulic performance decline under the impact of oil pressure, the problem that the present embodiment will solve makes clamper volume reduce exactly and performance is reliable equally.In the present embodiment, clamper is provided with slips, slips is the strength member of anchor packer, is common tailor-made mechanism of weighing anchor.Slips is arranged with master cylinder and auxiliary oil cylinder, and master cylinder comprises master cylinder cylinder body and main oil cylinder piston, and auxiliary oil cylinder comprises auxiliary oil cylinder cylinder body and auxiliary oil cylinder piston, main oil cylinder piston and auxiliary oil cylinder piston reverse motions; Slips periphery is arranged with right slip spider and left slip spider, master cylinder cylinder body is connected with right slip spider by the fore-set being set in left slip spider inside, butterfly spring is provided with inside auxiliary oil cylinder cylinder body, cylindrical spring is provided with between right slip spider and left slip spider, utilize the pretightning force of spring to overcome drilling tool deadweight like this, make master cylinder unclamp clamper.Promote master cylinder cylinder body to move right when hydraulic oil enters master cylinder, by fore-set, power is passed to right slip spider, right slip spider moves to right, and disc spring is compressed.Simultaneously under the effect of cylindrical spring, left slip spider moves to left and unclamps drilling tool.Overcome the pretightning force of spring and auxiliary oil cylinder with joint efforts making a concerted effort of drilling tool deadweight and rig torque, the present embodiment has that volume is little, structure simple, the feature of dependable performance, and clamps drilling tool when also can realize unexpected power-off.
Certainly; the utility model can also have other various embodiments; when not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and distortion according to the utility model, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the utility model.
