Description

Technical Field

[0001] This utility model relates to the field of oil drilling technology, and in particular to a linkage-type pipe clamp. Background Technology

[0002] With the continuous improvement of automation in oil drilling operations, automated drilling tool operation equipment such as top drives, iron drills, automatic pipe runners, and drilling platform robots have been widely used in the field. Among them, the clamping device used to directly hold the pipe tools, as the core execution structure for tripping and running the drill string, not only directly determines the accuracy of the operation, but is also a key prerequisite for ensuring the safety of drilling workers.

[0003] In drilling operations, existing robotic grippers require frequent changes in size to accommodate different pipe diameters. When faced with gripping conditions of different specifications, the machine must be stopped to replace the corresponding gripper model. This discontinuous operation mode not only disrupts the continuity of the tripping process but also consumes a significant amount of effective working time due to repeated disassembly and adjustment, thus significantly hindering the improvement of drilling efficiency.

[0035] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] like Figure 1 As shown, this utility model embodiment provides a linkage-type pipe clamp, which includes a clamp body 1 and a clamp seat 2. The clamp body 1 is disposed in the clamp seat 2. The clamp body 1 is used to clamp the upper middle part of the pipe 7 so that the center of gravity of the pipe 7 is located below the clamp body 1.

[0037] like Figure 2 As shown, the clamp body 1 includes a drive member 11, a connecting rod assembly 12, and a gripper assembly 13. The fixed end of the drive member 11 is horizontally oriented and connected to the clamp seat 2. The horizontal orientation of the fixed end of the drive member 11 and its connection to the clamp seat 2 enable the driving force to be transmitted in the horizontal direction, thus avoiding uneven force on the gripper assembly 13 due to deviation in the driving direction.

[0038] like Figure 2 and Figure 3 As shown, the gripper assembly 13 includes at least one fixed tooth 131, two rotating teeth 132, and multiple tooth seats 134. In this embodiment, the gripper assembly 13 adopts a circumferential arrangement of two fixed teeth 131 and two rotating teeth 132. The fixed teeth 131 can serve as a clamping reference, providing a stable support point for the pipe 7. The two rotating teeth 132 cooperate with the fixed teeth 131 to achieve clamping by moving in opposite directions or towards each other. At the same time, the circumferential distribution of multiple teeth can increase the contact area with the pipe 7, making the force on the pipe 7 more uniform and further avoiding the problem of insecure clamping.

[0039] The die holders 134 are respectively configured to correspond one-to-one with the fixed die 131 and the rotating die 132. The clamp seat 2 is provided with a fixed seat 133. The fixed die 131 is detachably connected to the fixed seat 133 through the die holder 134. The two rotating dies 132 are respectively detachably connected to the two moving ends of the connecting rod assembly 12 through the die holder 134. Since the fixed die 131 and the rotating die 132 are detachably connected to the fixed seat 133 and the connecting rod assembly 12 through the die holder 134, there is no need to replace the entire clamp. Only the appropriate die holder 134 needs to be replaced according to the different pipe diameters of the pipe 7, which reduces the downtime for changing the clamp. At the same time, after replacing the die holder 134, the center position of the clamped pipe 7 remains unchanged. This means that when the drilling rig body clamps pipes 7 of different diameters, there is no need to change the stroke of the telescopic arm on the drilling rig body, which effectively improves the continuity and efficiency of the operation, while ensuring the stability and reliability of the clamping operation.

[0040] The telescopic end of the drive component 11 is connected to the linkage assembly 12 to drive the two moving ends of the linkage assembly 12 to move the two rotating dies 132 in opposite directions or towards each other, so that the rotating dies 132 open and close to engage with the fixing die 131 to release or clamp the pipe 7. The linkage assembly 12 can stably convert the telescopic motion of the drive component 11 into the opening and closing action of the gripper assembly 13, ensuring that the gripper assembly 13 moves synchronously and symmetrically, thereby improving the stability and accuracy of clamping.

[0041] like Figure 3 As shown, the linkage assembly 12 includes a drive block 121, two transmission members 122, and two swing plates 123, with the two swing plates 123 forming two moving ends. Two rotating teeth 132 are respectively disposed on the two swing plates 123. The two swing plates 123 are arranged opposite each other and are respectively hinged to the clamp seat 2 through a third hinge shaft 124. The drive block 121 is connected to the drive end of the drive member 11. The first ends of the two transmission members 122 are both hinged to the drive block 121, and the second ends of the two transmission members 122 are respectively hinged to the two swing plates 123. When the drive member 11 drives the drive block 121 to extend, the drive block 121 drives the swing plates 123 to rotate around the third hinge shaft 124 through the two transmission members 122, so that the two swing plates 123 drive the rotating teeth 132 on them to open and close. The linkage assembly 12, through the cooperation of the drive block 121, two transmission components 122 and two swing plates 123, enables the driving force of the drive component 11 to be synchronously transmitted to the two transmission components 122 via the drive block 121, thereby driving the two swing plates 123 to rotate symmetrically around the third hinge axis 124. This ensures that the opening and closing actions of the two rotating jaws 132 are completely synchronized, avoiding the offset of the clamping of the pipe 7 due to inconsistent actions. In addition, the swing plate 123 is hinged to the clamp seat 2 through the third hinge axis 124, ensuring stable rotation and accurate clamping position.

[0042] like Figure 2As shown, the linkage assembly 12 also includes two guide blocks 125, which are respectively disposed at the upper and lower ends of the drive block 121. The clamp seat 2 is provided with a corresponding guide groove 241, and the guide blocks 125 are adapted to the guide groove 241. The cooperation between the guide blocks 125 and the guide groove 241 can guide the extension and retraction movement of the drive block 121, preventing the drive block 121 from horizontally deviating or wobbling during the movement, ensuring that the driving force is stably transmitted to the transmission component 122 and the swing plate 123 along the preset direction, thereby ensuring that the opening and closing action of the rotating jaw 132 is stable and consistent.

[0043] like Figure 4 and Figure 5 As shown, the clamp base 2 includes a top plate 21, a bottom plate 22, a guide seat 24, and two mounting plates 23. The two mounting plates 23 are positioned opposite each other and spaced apart on the bottom plate 22. The top plate 21 is positioned between the two mounting plates 23, forming a receiving space. One side of the receiving space is the clamping area. The telescopic end of the drive component 11 extends into the receiving space and connects to the linkage assembly 12. The receiving space can be used to integrate internal structures such as the gripper assembly 13 and the linkage assembly 12, making the overall layout more compact. The top plate 21 and the bottom plate 22 provide upper and lower supports for the mounting plates 23, enhancing the overall rigidity of the clamp base 2 and preventing deformation due to excessive force during clamping. The guide seat 24 is positioned on the bottom plate 22, and a guide groove 241 is formed on the guide seat 24 to match the guide block 125. Mounting slot 232 is provided on mounting plate 23. Part of swing plate 123 in link assembly 12 is located in mounting slot 232 and is hinged to mounting plate 23 via third hinge shaft 124, so as to facilitate the installation and swing of swing plate 123 in link assembly 12.

[0044] like Figure 2 As shown, fixed shafts 14 are respectively provided at the upper and lower ends of the fixed end of the drive component 11. The drive component 11 is connected to the tail ends of the top plate 21 and the bottom plate 22 respectively through the fixed shafts 14, which enhances the stability of the drive component 11 installation.

[0045] like Figure 4 As shown, the two side walls of the top plate 21 are respectively inserted into the mounting holes of the two mounting plates 23 and are detachably connected by a first connector. The bottom plate 22 is detachably connected to the mounting plates 23 by a second connector, thus facilitating the assembly and disassembly of the top plate 21, bottom plate 22, and mounting plates 23. When it is necessary to inspect or replace the internal components of the clamp, the top plate 21 and bottom plate 22 can be easily disassembled, improving maintenance convenience. The first and second connectors can be screws.

[0046] like Figure 6As shown, the linkage-type pipe clamp also includes a bracket 3. The clamp seat 2 is connected to the drilling rig body via the bracket 3. The bracket 3 is positioned above the clamp seat 2. The rear of the bracket 3 and the clamp seat 2 are elastically connected via an elastic connecting unit 4. The front of the bracket 3 and the clamp seat 2 are hinged via a first hinge shaft 5. The first hinge shaft 5 is located near the opening side of the clamp body 1, and the extended line of the axis of the first hinge shaft 5 is perpendicular to and intersects the axis of the pipe 7. The bracket 3 is hinged to the drilling rig body via a second hinge shaft 6. The extended line of the axis of the second hinge shaft 6 is perpendicular to and intersects the axis of the pipe 7. The axis of the first hinge shaft 5 is perpendicular to the axis of the second hinge shaft 6. The rear of the bracket 3 and the clamp seat 6 refers to the side near the drilling rig body.

[0047] In this implementation, such as Figure 1 As shown, the bracket 3 extends out from the tail end of the second hinge shaft 6 and is hinged to the main body of the drilling rig. The bracket 3 can swing left and right relative to the main body of the drilling rig around the axis of the second hinge shaft 6, thereby driving the clamp seat 2 to swing left and right. The clamp seat 2 can drive the clamp body 1 to swing back and forth relative to the bracket 3 around the axis of the first hinge shaft 5.

[0048] When the clamp body 1 is unloaded, the elastic connecting unit 4 keeps the clamp seat 2 in a horizontal state. The elastic connecting unit 4 and the first hinge shaft 5 jointly bear the weight of the clamp seat 2 and the clamp body 1 inside when unloaded, and will not hinder the clamp seat 2 from swinging around the first hinge shaft 5. At the same time, the elastic connecting unit 4 keeps the clamp seat 2 in a horizontal state when unloaded, ensuring that the clamp can quickly reset during continuous operation, reducing manual intervention and meeting the high requirements of automated drilling for operation accuracy and efficiency.

[0049] When the clamp body 1 clamps the inclined pipe 7, the clamp seat 2 can swing around the first hinge axis 5 and / or the second hinge axis 6. The clamp seat 2 drives the clamp body 1 to automatically adjust its angle to adapt to the axis of the inclined pipe 7, thereby achieving stable and accurate clamping of the pipe 7, avoiding problems such as insecure clamping and uneven force, and significantly improving clamping reliability. Furthermore, because the upper part of the pipe 7 is clamped and the center of gravity is located below the clamp, a stable suspension structure is formed. Through the vertical arrangement of the first hinge axis 5 and the second hinge axis 6, when the pipe 7 is lifted, the clamp seat 2 can swing adaptively around two orthogonal directions, so that the pipe 7 returns to a vertical state. Moreover, this centering pipe 7 clamp structure is simple and has low production cost.

[0050] like Figure 6As shown, the support 3 includes two swing rods 31 and two connecting crossbars 32. The two swing rods 31 are spaced apart and connected by the connecting crossbars 32. The second hinge shaft 6 is fixedly connected to the connecting crossbar 32 and located in the middle of the connecting crossbar 32. The tail end of the second hinge shaft 6 is hinged to the drilling rig body. The elastic connection unit 4 includes two elastic elements, which are arranged one-to-one with the two swing rods 31. The bottom end of the swing rod 31 is connected to the top end of the clamp seat 2 through the elastic element, and the front end of the swing rod 31 is hinged to the clamp seat 2 through the first hinge shaft 5. By specifically configuring the support 3 with two spaced swing rods 31 and a connecting crossbar 32 connecting them, the support 3 has a simple structure and strong stability, providing a stable support foundation for the clamp seat 2. Meanwhile, the elastic connection unit 4 is configured with two elastic elements that match the swing rod 31 one by one, which can make the clamp seat 2 more evenly stressed when unloaded, further ensuring the stability of the horizontal state. The two elastic elements cooperate with the swing rod 31 respectively, which can more accurately assist the clamp seat 2 to swing around the first hinge axis 5, improve the adaptive adjustment flexibility of the clamp under complex working conditions, and make the overall structure layout reasonable and easy to assemble.

[0051] like Figure 6 As shown, the swing arm 31 includes a horizontal part 311 and a vertical part 312 connected together. The horizontal part 311 is connected to the top of the mounting plate 23 of the clamp seat 2 via an elastic member. The vertical parts 312 of the two swing arms 31 are respectively hinged to the hinge slots 231 of the two mounting plates 23 via a first hinge axis 5. This allows the clamp seat 2 to be subjected to more balanced force under the symmetrical support of the two mounting plates 23, further improving the stability of swinging around the first hinge axis 5. By setting the swing arm 31 to a connection structure of the horizontal part 311 and the vertical part 312, and making the bottom end of the swing arm 31 connected to the top of the clamp seat 2 via an elastic member, the horizontal part 311 can provide a more stable force support point, avoiding force displacement of the elastic member.

[0052] In this embodiment, the elastic element is a helical compression spring, which has stable elastic properties and strong load-bearing capacity, effectively supporting the weight of the clamp seat 2 and the clamp body 1, ensuring that the clamp seat 2 reliably remains horizontal when unloaded. Furthermore, helical compression springs are low in cost, easy to procure, and convenient to replace, reducing the overall maintenance cost of the equipment.
