Abstract
The utility model provides a chain type clamping device which essentially comprises a V-shaped support, dental laminas, a chain, an adjusting device and a locking device, wherein, the supporting end surface of the V-shaped support is provided with two dental laminas; one end of the chain is locked by the locking device, and the other end goes through the locking device, and fixed on the V-shaped support by the adjusting device consisting of an adjusting nut and an adjusting screw, to form the clamping device. The locking device consists of a locking handle with a lower end in bulge type, a locking piece and a clamping pin. The chain type clamping device clamps the locking device and the adjusting device by the chain, and has higher clamping precision; the chain has large scope of applicable length, can uniformly clamp circular pipe fittings, and prevents drill shells from deforming. The chain type clamping device does not skid and bite the surface of a work piece when shackling and unshackling, has the advantages of simple operation and low cost, and is a claming device with wide scope of application.
Description
Technical field
The utility model relates to all kinds of oil of dismounting, the geology technical field with the tubing string workpiece device that is threaded, and relates in particular to a kind of being used under the oil well, the clamping device of instrument assembling and disassembling stand.
Background technology
At present, the clamping device of assembling and disassembling stand has cam clamped-in style and double V-shaped clamped-in style etc.The cam clamped-in style is that the cam block teeth directly contact with workpiece, damages workpiece easily; Double V-shaped clamped-in style is to adopt the clamping device of two V-types to block cylinder simultaneously, and cylinder discontinuity when this form clamps makes the cylinder distortion easily, and under the gripping range of this kind form, can only clamp the very interior cylinder of narrow diameter scope.
And for example a kind of tool clamp, it mainly is contained in respectively in the fan-shaped chamber of three off-centre operations in the housing along its off-centre operation cambered surface synchronously by three fan-shaped block teeth, and positive and negative transferring clamps or unclamps workpiece (drilling rod, downhole tool) around the center of circle of housing, and three block teeth are that cambered surface contacts with workpiece.This device can clamp automatically, and regulates the size of its clamping force automatically with the size of operation torque, and skid level is less.But this device ratio of precision is lower, and it is little to bear moment of torsion, and intensity is low, and it is big to adapt to pipe diameter, precision prescribed height, the dismounting of the workpiece that last shackle moment of torsion is big.
When we do not need especially accurate clamping pressure, when not having condition to adopt hydraulic pressure or other modes to the cylinder tube grip of different-diameter yet, just need a kind of simple to operate, clamping degree height, the tight diameter range of adjustable clamp, clamping device with low cost.
The utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of chain-type clamping device to be used for all kinds of oil, geology with the tubing string workpiece assembling and disassembling stand that is threaded, and goes up, the clamping work pieces during shackle.
The structure of the utility model chain-type clamping device comprises: V-type support, chain, adjusting device and locking device are formed, and its concrete structure is:
The support end face of V-type support is provided with two dental laminas; Chain one end is by locking device locking, and the other end passes locking device and is fixed on the V-type support by adjusting device, forms clamping device.
Described adjusting device is by adjusting nut and adjusting leading screw and form, and wherein, the adjustment nut is fixed on chain one end by the adjustment leading screw and forms adjusting device.
Described locking device is made up of set lever, stay, chucking pin, and wherein, set lever is that handle, at its lower end is the set lever of male-type.
During work,, by adjusting chain length, the cylinder of different tube diameters is clamped usually with V-type stent support cylinder pipe; The concrete adjustment mode of described chain-type clamping device is:
1 at first, unscrews the adjustment nut, adjusts by adjusting the chain that nut is fixed on V-type support one end, be adjusted to be fit to scope after, locking is adjusted nut pipe is clamped.
2. when scope that the chain length of need adjusting can be adjusted greater than adjusting device, will adjust the loose maximum position that arrives greatly of nut, break away from from the V-type support; Set lever by locking device unclamps stay, and distance increases between stay and the chucking pin, pulls out chain from locking device one end, adjust to Len req, fastening then set lever, set lever high spot and stay cooperate with the chucking pin, the locking locking device; Adjust nut and be fixed on the V-type support, pipe is clamped by tightening the adjustment nut.
Advantage of the present utility model is:
1. clamp by chain and adjusting device, clamping accuracy is higher, can realize the even clamping to circular pipe fitting, avoids the drilling tool housing distortion.
2. be provided with adjusting device and locking device, it is big that the chain prove-in length can be changed scope, increased the scope of application of pipe diameter, simple to operate, with low cost.
3, the support end face of V-type support is equipped with dental lamina, and is non-slip when making on the changer shackle, surface of the work does not bite.

The specific embodiment
As shown in Figure 1: the structure of the utility model chain-type clamping device is:
The support end face of V-type support 1 has been provided with two dental laminas 2, and chain 3 one ends are by locking device 5 lockings, and the other end is fixed on the V-type support 1 by adjusting device 4, forms clamping device.
Wherein, adjusting device 4 is fixed on chain 3 one ends by adjustment nut 9 by adjustment leading screw 10 and forms adjusting device 4.
In conjunction with Fig. 2 using method of the present utility model is described as follows:
During work,, by adjusting chain 3 length, the cylinder of different tube diameters is clamped usually with V-type support 1 support cylinder pipe; Concrete adjustment mode is:
1. the cylinder pipe is placed on the support end face of the V-type support 1 that dental lamina 2 is housed, chain 3 one ends are installed in locking on the locking device 5, and the other end is fixed on the V-type support 1 by adjusting nut 9; At first, unscrew and adjust nut 4, adjust by adjusting the chain 3 that nut 9 is fixed on V-type support 1 one ends, be adjusted to be fit to scope after, locking is adjusted 9 pairs of pipes of nut and is clamped.
When the chain length of need adjusting when adjusting 4 scopes that can adjust of nut, will adjust nut 4 pines and arrive maximum positions greatly, until from 1 disengaging of V-type support; Set lever 6 by locking device 5 unclamps stay 7, and distance increases between stay 7 and the chucking pin 8; Pull out chain 3 from locking device 5 one ends, adjust to Len req, fastening then set lever 6, set lever 6 high spots and stay 7 cooperate with chucking pin 8, locking locking device 5 clamps by tightening the 9 pairs of pipes of adjustment nut that are fixed on the V-type support 1.
The utility model has the advantage of:
1. clamp by chain and adjusting device, clamping accuracy is higher, can realize circular pipe fitting Evenly clamp, avoid the drilling tool housing distortion.
2. be provided with adjusting device and locking device, it is big that the chain prove-in length can be changed scope, increases The scope of application of pipe diameter, simple to operate, with low cost.
3, on the support end face of V-type support dental lamina is housed, non-slip when making on the changer shackle, Surface of the work does not bite.
