Description

Technical Field

[0001] This utility model relates to the field of double-sided locking technology, and in particular to a double-sided locking structure with uniform force distribution. Background Technology

[0002] Slips are tools used to hold and suspend the drill string and casing string during the tripping process in drilling. A brief introduction: Slips are tools used to hold and suspend the drill string and casing string during the tripping process in drilling. Structure: Slips consist of slip pieces, slip teeth, and a handle. The outer shape is conical, allowing it to wedge into the inner hole of the rotary table; the inner wall forms a circular hole, on which slip teeth are fitted. Basket-shaped slips are cylindrical, shaped like a basket. The outer surface of the slip has a complete, wide-toothed left-hand thread, which mates with the inner thread of the outer cylinder. The pitch is the same, but the tooth surface is much narrower, allowing it to move up and down a certain distance within the cylinder. The internal gripping teeth are also multi-start left-handed sawtooth threads. A keyway is provided at the lower end of the slip, which mates with a key on the control ring to prevent the slip from rotating within the cylinder. The slip has equally spaced expansion and contraction grooves along its longitudinal direction, allowing the inner diameter of the slip to expand or contract. Its sealing element is on the control ring.

[0003] An existing double-sided clamp with a uniform stress structure is not conducive to ensuring the stability and ease of operation after installation when workers cooperate with the equipment for actual operation and use. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a double-sided clamp with a uniform force-bearing structure.

[0005] This utility model is achieved by the following technical solution: a double-sided clamp with a uniform force structure, including a limiting support ring, a fixed frame fixedly connected to the bottom of the limiting support ring, a positioning plate clamped to the bottom of the fixed frame, and a double-sided clamp body fixedly connected to the bottom of the positioning plate.

[0006] A reinforcing support plate is fixedly connected to the surface of the double-sided slip body, and a fixed cross plate is fixedly connected to the surface of the reinforcing support plate. A damping groove is provided inside the double-sided slip body, and a damping sleeve is fixedly connected inside the double-sided slip body. A clamping arc plate is slidably connected inside the damping sleeve, and an anti-slip groove is provided inside the clamping arc plate.

[0007] Through the above technical solution, this symmetrical layout allows the clamping force to be applied evenly on both sides of the workpiece, effectively avoiding eccentric wear or deformation caused by unilateral force, and is particularly suitable for centering and clamping high-precision cylindrical workpieces.

[0008] As a further improvement to the above scheme, the number of the fixed frame and the positioning plate is set to two, and the two fixed frames and positioning plates are symmetrically distributed on the left and right sides with the limiting support ring as the center.

[0009] The above technical solution forms a three-dimensional support system by setting up two fixed frames and positioning plates symmetrically distributed around the limiting support ring, as well as double-sided clamp bodies installed on both sides.

[0010] As a further improvement to the above solution, the limiting support ring is located at the top of the double-sided slip body, and the bottom of the fixing frame is in contact with the top surface of the double-sided slip body.

[0011] As a further improvement to the above solution, the number of the double-sided slip bodies is set to two, and the two double-sided slip bodies are symmetrically distributed on the left and right sides with the limiting support ring as the center. The fixing cross plate is fixedly connected to the surface of the double-sided slip body.

[0012] Through the above technical solution, several reinforcing support plates and fixed cross plates are staggered on the surface of the double-sided slip body to form a grid-like reinforcement layer, which upgrades the traditional flat slip into a truss-type load-bearing structure. This not only reduces the overall weight, but also reduces the risk of local stress concentration through the principle of multi-point force distribution, so that the device can still maintain dimensional stability when subjected to high-frequency vibration conditions.

[0013] As a further improvement to the above scheme, the number of the reinforcing support plate and the fixed cross plate is set to several, and the several reinforcing support plates and the fixed cross plate are symmetrically distributed on the left and right sides with the limiting support ring as the center.

[0014] As a further improvement to the above solution, the number of damping sleeves is set to several, and the several damping sleeves are equidistantly distributed around the double-sided slip body, and the clamping arc plate is slidably connected inside the double-sided slip body.

[0015] As a further improvement to the above solution, the clamping arc plate is slidably connected inside the damping groove, and the number of anti-slip support grooves is set to several, with the several anti-slip support grooves being equidistantly distributed around the clamping arc plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes damping sleeves and damping grooves evenly distributed inside the double-sided clamp body to form a linear guide rail. Combined with a sliding clamping arc plate, when clamping workpieces of different diameters, the clamping arc plate moves smoothly along the damping groove. The multi-segment spiral pattern of its built-in anti-slip support groove generates progressive friction, preventing slippage and overload impact, thus achieving adaptive locking. By setting a limiting support ring at the top to constrain the axial displacement of the fixed frame, and a bottom positioning plate to limit the radial offset of the double-sided clamp body, a double safety mechanism is formed.

[0018] This utility model sets up a clamping arc plate as an independent functional module and uses a damping sleeve to achieve quick assembly and disassembly. Operators can replace the arc plate with different curvature radii according to processing needs without adjusting the main structure. The equidistant distribution design of the anti-slip support grooves also facilitates cleaning and maintenance, effectively extending the service life of vulnerable parts.

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Example:

[0027] Please combine Figure 1-4 The double-sided chock with a uniform force structure in this embodiment includes a limiting support ring 1, a fixed frame 2 fixedly connected to the bottom of the limiting support ring 1, a positioning plate 3 snapped into the bottom of the fixed frame 2, and a double-sided chock body 4 fixedly connected to the bottom of the positioning plate 3.

[0028] A reinforcing support plate 5 is fixedly connected to the surface of the double-sided slip body 4. A fixed cross plate 6 is fixedly connected to the surface of the reinforcing support plate 5. A damping groove 7 is provided inside the double-sided slip body 4. A damping sleeve 8 is fixedly connected inside the double-sided slip body 4. A clamping arc plate 9 is slidably connected inside the damping sleeve 8. An anti-slip support groove 10 is provided inside the clamping arc plate 9.

[0029] This symmetrical layout allows the clamping force to be applied evenly on both sides of the workpiece, effectively avoiding eccentric wear or deformation caused by unilateral force, and is particularly suitable for centering and clamping high-precision cylindrical workpieces.

[0030] The number of fixed frames 2 and positioning plates 3 is set to two. The two fixed frames 2 and positioning plates 3 are symmetrically distributed on the left and right sides with the limiting support ring 1 as the center. The damping sleeves 8 and damping grooves 7 are set to form a linear guide rail by setting the damping sleeves 8 and damping grooves 7 equally distributed inside the double-sided clamp body 4. With the cooperation of the sliding clamping arc plate 9, when clamping workpieces of different diameters, the clamping arc plate 9 moves smoothly along the damping groove 7. The multi-segment spiral pattern of its built-in anti-slip support groove 10 generates progressive friction force, which prevents slippage and overload impact, and realizes adaptive locking. By setting the top of the limiting support ring 1 to constrain the axial displacement of the fixed frame 2, and the bottom positioning plate 3 to restrict the radial displacement of the double-sided clamp body 4, a double insurance is formed.

[0031] A three-dimensional support system is formed by setting up two fixed frames 2 and a positioning plate 3 symmetrically distributed around the limiting support ring 1, as well as a double-sided clamp body 4 installed on both sides.

[0032] The limiting support ring 1 is located at the top of the double-sided slip body 4, and the bottom of the fixing frame 2 is in contact with the top surface of the double-sided slip body 4.

[0033] The number of double-sided slip bodies 4 is set to two. The two double-sided slip bodies 4 are symmetrically distributed on the left and right with the limiting support ring 1 as the center. The fixing plate 6 is fixedly connected to the surface of the double-sided slip body 4.

[0034] Several reinforcing support plates 5 and fixed cross plates 6 are staggered on the surface of the double-sided slip body 4, forming a grid-like reinforcement layer. This upgrades the traditional flat slip into a truss-type load-bearing structure, which not only reduces the overall weight but also reduces the risk of local stress concentration through the principle of multi-point force distribution, so that the device can still maintain dimensional stability when subjected to high-frequency vibration conditions.

[0035] The number of reinforcing support plates 5 and fixed cross plates 6 is set to several, and the several reinforcing support plates 5 and fixed cross plates 6 are symmetrically distributed on the left and right sides with the limiting support ring 1 as the center.

[0036] The number of damping sleeves 8 is set to several, and the damping sleeves 8 are equidistantly distributed around the double-sided slip body 4. The clamping arc plate 9 is slidably connected inside the double-sided slip body 4. By setting the clamping arc plate 9 as an independent functional module, quick assembly and disassembly can be achieved through the damping sleeves 8. Operators can replace the arc plate with different curvature radii according to processing requirements without adjusting the main structure. The equidistant distribution design of the anti-slip support grooves 10 also facilitates cleaning and maintenance, effectively extending the service life of vulnerable parts.

[0037] The clamping arc plate 9 is slidably connected inside the damping groove 7. The number of anti-slip support grooves 10 is set to several, and the several anti-slip support grooves 10 are equidistantly distributed with the clamping arc plate 9 as the center.

[0038] The implementation principle of a double-sided clamp with a uniform force structure in this embodiment is as follows: By setting damping sleeves 8 and damping grooves 7 equidistantly distributed inside the double-sided clamp body 4 to form a linear guide rail, and cooperating with a sliding clamping arc plate 9, when clamping workpieces of different diameters, the clamping arc plate 9 moves smoothly along the damping groove 7, and the multi-segment spiral pattern of its built-in anti-slip support groove 10 generates progressive friction force, which prevents slippage and overload impact, and achieves adaptive locking. By setting the top of the limiting support ring 1 to constrain the axial displacement of the fixed frame 2, and the bottom positioning plate 3 to limit the radial displacement of the double-sided clamp body 4, a double insurance is formed. By setting the clamping arc plate 9 as an independent functional module, quick disassembly and assembly are achieved through the damping sleeves 8. Operators can replace the arc plate with different curvature radii according to processing needs without adjusting the main structure. The equidistant distribution design of the anti-slip support groove 10 also facilitates cleaning and maintenance, and effectively extends the service life of vulnerable parts.
