Abstract
The utility model discloses a roller clamping device for drilling tools. The roller clamping device comprises two clamping forceps bodies, wherein the middle parts of the two clamping forceps bodies are hinged; one end of each clamping forceps body is respectively provided with a pair of supporting plates; the supporting plates of the two clamping forceps bodies are respectively hinged with a pair of clamping wheel rollers, and a clamping cylinder is hinged between the other ends of the two clamping forceps bodies; and a cylinder body end of the clamping cylinder is hinged with one clamping forceps body, and a piston end of the clamping cylinder is hinged with the other clamping forceps body. The roller clamping device disclosed by the utility model has the advantages that no dumping and falling for the drilling tools can be ensured in the process of clamping and centering the drilling tool, the rotation of the drilling tool can not be limited, meanwhile, the suitability for different types of drilling tools also can be achieved, and automatic centering and alignment can be realized for the drilling tools with different diameters.
Description
Technical field
The utility model relates to oil drilling and extracting equipment, relates in particular to the roller clamper that a kind of drilling tool lifting manipulator is used.
Background technology
When drilling tool lifting manipulator is a kind of oil drilling or workover treatment, in order to the instrument of lifting drilling tool.In the prior art, lifting manipulator need to be changed corresponding centering machine when clamping different-diameter specification drilling tool, and labour intensity is large; In drilling process, need to make up a joint, the operation such as trip-out, in these operating process, need to rotate drilling tool, and existing machinery generally only has pincers tooth clamper on hand, after pincers tooth clamp holder clamping drilling tool, can not rotate with drilling tool, it has limited the rotation of drilling tool.This just need to unclamp pincers tooth clamper, could realize the rotation of drilling tool.And now drilling tool does not also connect or does not thread off completely, easily topple over, fall, cause device damage and personnel casualty accidents.This is just badly in need of providing a kind of can also play centralizing function to drilling tool after the pincers tooth clamper of release mechanism hand, can guarantee that drilling tool can not topple over, fall in the process of clamping, righting drilling tool simultaneously, can not limit the roller clamper of drilling tool rotation.
Utility model content
In order to solve the problems of the prior art, the purpose of this utility model is to provide a kind of drilling tool that can clamp different-diameter specification, does not also limit the roller clamper of drilling tool rotation simultaneously.
For achieving the above object, the utility model is by the following technical solutions: a kind of drilling tool roller clamper comprises that two clamp calipers, described two middle parts that clamp caliper are hinged, and described two one end that clamp caliper are respectively equipped with a pair of gripper shoe, be hinged with respectively a pair of pinch wheels and roll in the gripper shoe of described two clamping calipers; Between the other end of two clamping calipers, be hinged with clamping cylinder; The cylinder body end of clamping cylinder and one of them clamping caliper are hinged, and the piston end of clamping cylinder and another clamping caliper are hinged.
The utility model adopts above technical scheme, utilize two clamping caliper middle parts hinged, two clamp caliper one end and are respectively equipped with a pair of pinching roller, between the other end, be provided with the structure of clamping cylinder, by two closures that clamp caliper of extension and contraction control of clamping cylinder, utilize four pinching rollers to realize the clamping of drilling tool and righting, pinching roller is in clamping the process of drilling tool, pinch wheels is rolled and can be rotated with drilling tool, thereby realization can guarantee drilling tool in the process of clamping, righting drilling tool, can not topple over, fall, can not limit drilling tool rotation.Adopt in addition the clamping mode of four pinching rollers, can adapt to the drilling tool of different size, to the drilling tool of different-diameter, can realize self-centering, align.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, further describe the utility model:
Fig. 1 is the perspective view of a kind of drilling tool roller of the utility model clamper;
Fig. 2 is the structural representation of facing of a kind of drilling tool roller of the utility model clamper;
Fig. 3 is the side-looking structural representation of a kind of drilling tool roller of the utility model clamper;
When being a kind of drilling tool roller of the utility model clamper clamping drilling tool, Fig. 4 faces structural representation.
The specific embodiment
One of as shown in Figure 1 to Figure 4, a kind of drilling tool roller clamper comprises that two clamp caliper 1, 2, described two clamp caliper 1, 2 middle part is hinged by bearing pin, and described two clamp caliper 1, one end of 2 is respectively equipped with a pair of gripper shoe 3, described two clamp caliper 1, in 2 gripper shoe 3, be hinged with respectively a pair of pinch wheels and roll i.e. totally four pinching rollers of 4(), two clamp caliper 1, between 2 the other end, be hinged with clamping cylinder 5, the cylinder body end 51 that is to say this clamping cylinder 5 is hinged with one of them clamping caliper 1, the piston end 52 of clamping cylinder 5 is hinged with another clamping caliper 2.
When needs clamp drilling tool 6, drive clamping cylinder 5 to shrink, clamp caliper 1,2 and drive pinching rollers 4 to open, drilling tool 6 is sent between four pinching rollers 4.Then drive clamping cylinder 5 to stretch, clamp caliper 1,2 and drive pinching roller 4 closures, realize the clamping to drilling tool 6.Pinching roller 4 can rotate with drilling tool 6, can not limit the rotation of drilling tool 6, and in the process clamping, four are stepped up roller 4 and can realize the self-centering to drilling tool 6 simultaneously.
