Detailed Description

The present invention is described in terms of particular embodiments, other advantages and features of the utility model will become apparent to those skilled in the art from the following disclosure, and it is to be understood that the described embodiments are merely exemplary of the utility model and that it is not intended to limit the utility model to the particular embodiments disclosed. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to the attached drawings 1-4 of the specification, the curtain grouting drilling tripping anti-squeezing safety fork clamp comprises a first front fork end 1, a second front fork end 2 is installed on one side of the first front fork end 1, and one end of the second front fork end 2 is connected with a lifting mechanism.

Mention the mechanism including setting up the fork pincers body 3 in 2 one ends of second front fork end, fork pincers body 3 top is connected with prevents extrudeing bracelet 4, and 3 one side of fork pincers body is connected with oblique extrusion support 5, is formed with guide way 6 between first front fork end 1 and the second front fork end 2, and 6 one side of guide way are provided with embedded groove 7, and embedded groove 7 one side is provided with laminating groove 8.

In some embodiments, as shown in fig. 1-2, the first front fork head 1 and the second front fork head 2 are similar in shape and same in size, and the first front fork head 1 and the second front fork head 2 are symmetrically arranged at a horizontal position with respect to the center of the bottom of the anti-squeezing bracelet 4, so that the first front fork head 1 and the second front fork head 2 are symmetrically arranged, and thus the tripping side is grooved to form an embedded joint. And the symmetry sets up and can play stable fork operation to the tripping both sides, improves the stability of the in-process of forking, and the shape of laminating groove 8 cross section sets up to semi-circular, and the shape of guide way 6 cross section sets up to isosceles trapezoid.

So that laminating groove 8 is semi-circular, inserts the back of the side inslot of the pipe trip both sides when first front fork end 1 and second front fork end 2 like this, by laminating groove 8 and the phase-match of the junction position department of pipe trip, the laminating of semicircular form, can laminate inseparabler. Support effect is better when upwarping the support, and the laminating is supported, prevents that extrusion bracelet 4 is the round steel preparation of buckling and adopts welded fastening with 3 tops of the fork pincers body, and fork pincers body 3 and 2 welded fastening in second front fork end to prevent that extrusion bracelet 4 can adopt the preparation of buckling. Prevent extrudeing intensity of bracelet 4 after the preparation is higher to prevent that extrusion bracelet 4 is connected more firmly with the fork-lift wrench pincers body 3, drive the effect that the fork-lift wrench pincers body 3 lifted and produced the linkage when mentioning and prevent extrusion bracelet 4 like this. Welded fastening between the oblique extrusion support 5 and the fork clamp body 3, contained angle number of degrees that forms between oblique extrusion support 5 and the 3 bottom faces of the fork clamp body is twenty degrees to alright can drive the fork clamp body 3 and shift up through lifting oblique extrusion support 5, and present twenty degrees and just be applicable to the hand and support, can effectively avoid the hand pressurized to damage, play better guard action, the durability is better.

In some embodiments, as shown in fig. 3 to 4, a connection ring 9 is disposed outside the anti-squeezing bracelet 4, a soft rubber ring 10 is disposed outside the connection ring 9, a plurality of first friction strips 11 are disposed outside the soft rubber ring 10, friction grooves 12 are formed in outer walls of the first friction strips 11, a long rubber ring 13 is disposed outside the oblique squeezing bracket 5, and a plurality of second friction strips 14 are connected outside the long rubber ring 13, so that a hand of a person can hold an upper surface of the first friction strips 11. And when the first friction strip 11 is held under stress, the first friction strip can be attached to the inner wall of the friction groove 12, so that the friction force is increased. And play the effect of buffering by go-between 9 and flexible glue ring 10, personnel's hand is difficult for wearing and tearing hemorrhage like this, can be at the perk in-process, and the difficult callus that grinds out and bleed scheduling problem takes place to rectangular rubber ring 13 outside can be held to another hand, plays the effect of increasing friction power through a plurality of second friction strips 14.

And rectangular rubber ring 13 can play the effect of buffering, at the in-process of mentioning oblique extrusion support 5, be difficult for causing hand wearing and tearing, it is more comfortable, go-between 9 outside and soft glue ring 10 inside adopt AB glue to glue fixedly and go-between 9 inside with prevent that to extrude bracelet 4 outside and adopt AB glue to glue fixedly, a plurality of first friction strips 11 are annular equidistance and distribute the setting, so that go-between 9 and soft glue ring 10 and prevent that to extrude bracelet 4 to connect more firmly. Simultaneously a plurality of first rubbing strips 11 can increase the frictional force of hand palm to the callosity is difficult for appearing in the friction, and a plurality of second rubbing strips 14 adopt the integrated into one piece of moulding plastics with rectangular rubber ring 13, and a plurality of second rubbing strips 14 are annular equidistance and distribute the setting, so that second rubbing strip 14 can be with rectangular rubber ring 13 integrated into one piece with low costs, and the preparation is convenient, and a plurality of second rubbing strips 14 increase multiple spot position frictional force.

The using process of the utility model is as follows:

when the anti-extrusion bracelet is used, one hand can be held outside the anti-extrusion bracelet 4, the other hand can be held outside the oblique extrusion bracket 5, and then the first front fork end 1 and the second front fork end 2 are aligned in the groove of the tripping side.

Then promote to one side to the oblique extrusion support 5 of shape and prevent extrudeing bracelet 4, can make and prevent that extrusion bracelet 4 and oblique extrusion support 5 drive the fork tong body 3 simultaneously and remove, and the fork tong body 3 drives first front fork end 1 and second front fork end 2 and enters into down the side groove of drilling, along the guide way 6 entering embedded groove 7 in, enters into laminating groove 8 along embedded groove 7 and accomplishes the laminating joint.

Upwards lifting up after that prevents extrudeing bracelet 4 and oblique extrusion support 5 can lift on the brill that pulls out down, and the convenient brill that will pull out down takes out like this, and the hand is placed position department and all can not receive and is pushed down to avoid the hand to push down and cause the incident, operation security is higher.

Although the utility model has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements may be made based on the utility model. Accordingly, such modifications and improvements are intended to be within the scope of the utility model as claimed.

In the present specification, the terms "upper", "lower", "left", "right", "middle", and the like are used for clarity of description, and are not intended to limit the scope of the present invention, and changes or modifications in the relative relationship thereof may be made without substantial technical changes.
