Abstract
The utility model discloses a top drive pipe column connecting device. A torque frame is connected with a clamping tong body through a floating hydraulic cylinder, the clamping tong body comprises a clamping tong shell, two cavities and a square hole are reserved in the clamping tong shell, the two cavities are used for installing sliding tong heads, the square hole is used for the clamping tong body to penetrate in, and the two sliding tong heads are arranged in the two corresponding cavities respectively. According to the top drive pipe column connecting device, the torque frame is connected with the clamping tong body through the hydraulic cylinder with the dual functions of telescoping and floating, a conventional spring mechanism of a back-up tong is omitted, and the function that the clamping tong body slides up and down along the torque frame is added; a front open structure is adopted for the clamping tong body of the pipe column connecting device, so that a pipe column to be connected enters the clamping tong body right in front, and the position, relative to clamping tong teeth, of a pipe column connector is convenient to observe, so that the pipe column is more convenient, rapid and reliable to connect in drilling operation.
Description
Technical field
The utility model belongs to oil drilling equipment technical field, relates to a kind of top and drives pipe connector.
Background technology
Drive carrying out in drilling operation course on top, the tubing string of delivering to well head need to be driven to central tube (or protection pipe nipple) with top and dock to continue and creep into.But the connection that joined conventional back-up tong can be used for tubing string is driven on existing top, but it is loop configuration, tubing string to be connected must under back-up tong in guide way enters caliper, can not watch the relative position of casing adapter in loop configuration (drilling rod is that joint, drill collar are body) and back-up tong pincers tooth.In addition; existing top is driven back-up tong and is not had and slide up and down and float function; when make-up operation, must rely on top to drive the move about fine setting that could realize casing adapter to be connected and central tube (or protection pipe nipple) joint of main body dock, relies on top to drive the main body above tripping function of tube connector column joint and central tube (or protecting pipe nipple) joint in shackle process of realization of floating; cause operating cumbersome, regulate difficulty large.
Utility model content
The purpose of this utility model is to provide a kind of top and drives pipe connector, has solved top of the prior art and has driven the problem that back-up tong can not be gone up slips, float and be inconvenient to observe when tubing string connection.
The technical solution adopted in the utility model is, pipe connector is driven on a kind of top, comprises moment of torsion frame, float fluid cylinder and clamping caliper, and moment of torsion frame is connected by unsteady fluid cylinder with clamping caliper; Described clamping caliper comprises gripper clamp housing, in gripper clamp housing, leave two cavitys of slip binding clip and the square hole that can penetrate for clamping caliper are installed, in two corresponding cavitys, be respectively arranged with a set of slip binding clip, the tailpiece of the piston rod of the rear portion of slip binding clip and binding clip fluid cylinder is in transmission connection, and the bottom of binding clip fluid cylinder is fixed in gripper clamp housing.
Pipe connector is driven on top of the present utility model, is further characterized in that:
Gripper clamp housing is by upper and lower panel and embedded gusset is assembled is formed by connecting.
The front portion of slip binding clip is provided with pincers tooth.
The beneficial effects of the utility model are that this pipe connector adopts the clamping caliper of the two slip binding clips of open front formula, makes tubing string to be connected can enter from dead ahead clamping caliper, facilitates the relative position of observation tube column joint and back-up tong pincers tooth; The while clamping caliper of pipe connector is connected by relocatable fluid cylinder with moment of torsion frame, by the tripping function in shackle process in the unsteady realization of caliper, avoids relying on top to drive the trouble that main body is unsteady, makes tubing string in drillng operation connect convenient quick.
Brief description of the drawings
Fig. 1 is the main TV structure schematic diagram of the utility model device;
Fig. 2 is the plan structure schematic diagram of the utility model device.
In figure, 1. moment of torsion frame, the fluid cylinder that 2. floats, 3. clamping caliper, 4. gripper clamp housing, 5. slip binding clip, 6. pincers tooth, 7. binding clip fluid cylinder, 8. tubing string, 9. square hole.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in Figure 1, Figure 2, the structure that pipe connector is driven on the utility model top is, comprise and can drive moment of torsion frame 1 that main body is connected with top, there is the unsteady fluid cylinder 2 of Telescopic and for clamping the open front formula clamping caliper 3 of tubing string, moment of torsion frame 1 lower end penetrates in the square hole of clamping caliper 3, between moment of torsion frame 1 and clamping caliper 3 both bearing pin otic placodes, is connected with the fluid cylinder 2 that floats;
Clamping caliper 3 comprises gripper clamp housing 4, slip binding clip 5, pincers tooth 6, binding clip fluid cylinder 7, gripper clamp housing 4 is wherein by upper, lower panel and embedded gusset is assembled be formed by connecting (fixing by bolt-locking or welding manner), in gripper clamp housing 4, leave two cavitys of slip binding clip 5 and the square hole 9 that can penetrate for clamping caliper 3 are installed, in two corresponding cavitys, be respectively arranged with a set of slip binding clip 5, the front portion of slip binding clip 5 is provided with the rotatable pincers tooth 6 that clamping tubing string is used, the tailpiece of the piston rod of the rear portion of slip binding clip 5 and binding clip fluid cylinder 7 is in transmission connection, the bottom of binding clip fluid cylinder 7 is fixed in gripper clamp housing 4.
The utility model device, the tubing string that while can be used in drillng operation, drive on top connects operation, its operating principle is: in drilling operation course, tubing string 8 to be connected is sent to well head center by the open front of clamping caliper 3, top is driven main body and is moved to after correct position, control the flexible of the fluid cylinder 2 that floats, making to clamp caliper 3 slides along moment of torsion frame 1, can reliably clamp after the joint of tubing string 8 wait clamping tooth 6, left and right binding clip fluid cylinder 7 synchronously stretches out by hydraulic system effect, promote slip binding clip 5 and the centripetal clamping of pincers tooth 6 mounted thereto, left, right pincers tooth 6 is embraced the joint of tubing string to be connected 8 simultaneously, main shaft rotation is driven on top, and central tube and tubing string carry out spinner, and after spinner completes, binding clip fluid cylinder 7 is retracted slip binding clip 5 is retracted to initial position, and top is driven and continued to creep into, and connects operation thereby complete tubing string.Connect in spinner process, unsteady fluid cylinder 2 is in quick condition under HYDRAULIC CONTROL SYSTEM, and clamping caliper 3 is able to along moment of torsion frame 1 free floating, thereby meets the needs of tripping; The moment of torsion producing in spinner operation, be delivered to slip binding clip 5 by pincers tooth 6, be delivered to gripper clamp housing 4 by the housing gusset contacting with slip binding clip 5 again, then be delivered to moment of torsion frame 1 by housing square hole 9, moment of torsion frame 1 drives to be connected with top and is finally delivered on drilling derrick.
