Description

Technical Field

[0001] This utility model relates to the field of oil drilling technology, specifically an oil drilling pipe clamp. Background Technology

[0002] Oil is a fluid mineral buried deep underground. During the extraction and transportation of oil, digging operations are required, and a large amount of water is used to cool the drill bit. After the digging is completed, casing needs to be installed. After a large number of pipelines are transported to the site, equipment is frequently used to pick them up and install them.

[0003] Chinese utility model patent CN222991468U discloses an oil drilling pipe clamp, which includes two protective frames connected by a connecting block. Symmetrical clamps are rotatably mounted within each of the two protective frames, and each clamp is equipped with a pipe-adaptive component. One of the protective frames contains a drive component, and a synchronization component is provided between the clamps in the two protective frames. This device utilizes multiple flexible clamping plates and springs to automatically deform when clamping pipes, thus adapting to pipes of different diameters. It has a wide range of applications and good clamping effect. The device uses two sets of clamps to simultaneously grip the pipes, reducing the impact of pipe center of gravity shift on the clamps, improving gripping effect and safety. The device uses a drive rod to synchronously connect the two sets of clamps, requiring only a single motor and reducer for drive, resulting in a simple structure and low manufacturing cost.

[0004] The existing device is not convenient for flexibly adjusting the gripper spacing. When dealing with long pipes, the fixed gripper spacing is difficult to adapt to the pipe length and cannot accurately place the clamping point in the appropriate position on the pipe. This will cause uneven force on the long pipe during the clamping process, which is prone to shaking. This not only affects the stability of transportation, but may also increase the risk of pipe collision damage. Therefore, there is a problem that it is not convenient to adjust the gripper spacing.

[0005] To address these issues, this invention provides an oil drilling pipe clamp. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an oil drilling pipe clamp that solves the aforementioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an oil drilling pipe clamp, comprising a protective frame, an adjusting mechanism slidably connected to the inner wall of the protective frame, a clamping mechanism fixedly connected to the outer surface of the adjusting mechanism, the adjusting mechanism comprising a connecting block slidably connected to the inner wall of the protective frame, a movable frame fixedly connected to the lower surface of the connecting block, the clamping mechanism comprising a fixed frame fixedly connected to the outer surface of the movable frame, a telescopic frame slidably connected to the inner wall of the fixed frame, a lower pressure plate fixedly connected to the lower surface of the telescopic frame, and a roller rotatably connected to the lower surface of the lower pressure plate.

[0008] Furthermore, a limiting block is fixedly connected to the outer surface of the telescopic frame, and the outer surface of the limiting block is slidably connected to the outer surface of the fixed frame.

[0009] By adopting the above technical solution, the limiting block helps to prevent the telescopic frame and the fixed frame from separating.

[0010] Furthermore, a spring is fixedly connected to the inner wall of the fixed frame, and the other end of the spring is fixedly connected to the upper surface of the telescopic frame.

[0011] By adopting the above technical solution, the telescopic frame and the lower pressure plate are made elastic by springs, which makes it easy to pressurize and limit pipes of different sizes.

[0012] Furthermore, two sets of gripper blocks are rotatably connected to the outer surface of the fixed frame, and a hydraulic telescopic rod is hinged to the upper end of the gripper block, and the inner wall of the gripper block is fixedly connected to a rubber pad.

[0013] By adopting the above technical solution, the output end of the hydraulic telescopic rod is extended by activating the hydraulic telescopic rod, which facilitates the adjustment of the angle of the two sets of gripper blocks, thereby facilitating the clamping and limiting of pipes of different sizes.

[0014] Furthermore, the outer surface of the movable frame is threaded with a fixing bolt, which is threaded onto the outer surface of the fixed frame.

[0015] Using the above technical solution, the fixed frame and the movable frame can be easily connected together by fixing bolts.

[0016] Furthermore, the adjustment mechanism also includes a geared motor fixedly connected to the outer surface of the protective frame. The output shaft of the geared motor is fixedly connected to a bidirectional threaded rod, which is rotatably connected to the inner wall of the protective frame. The outer surface of the bidirectional threaded rod is threadedly connected to the outer surface of the connecting block.

[0017] By adopting the above technical solution, the output shaft of the geared motor drives the bidirectional threaded rod to rotate, and the rotation of the bidirectional threaded rod drives the two sets of connecting blocks to move in opposite directions, thereby facilitating the adjustment of the distance between the two sets of moving frames and facilitating the stable clamping of pipes of different lengths.

[0018] Beneficial effects

[0019] This utility model provides an oil drilling pipe clamp. Compared with the prior art, it has the following advantages:

[0020] 1. The oil drilling pipe clamp, driven by a geared motor and a bidirectional threaded rod, can adjust the distance between the two sets of clamping mechanisms to precisely clamp the middle of a long pipe. This middle clamping method can balance the force on the pipe, reduce the shaking caused by the weight distribution at both ends during transportation, significantly increase the stability of the pipe during movement, and further improve transportation safety.

[0021] 2. This oil drilling pipe clamp uses a spring to allow the lower pressure plate to apply elastic pressure and limit the movement, a hydraulic telescopic rod to adjust the angle of the clamp block, and a rubber pad to increase friction. The three components work together to securely clamp pipes of different sizes. The limit block prevents the telescopic frame from detaching, and the fixing bolts ensure a firm connection, guaranteeing stability during the clamping process and preventing the pipe from slipping and getting damaged.

[0029] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] Reference Figures 1 to 4 This application provides an oil drilling pipe clamp, including a protective frame 1. An adjustment mechanism 2 is slidably connected to the inner wall of the protective frame 1, and a clamping mechanism 3 is fixedly connected to the outer surface of the adjustment mechanism 2. The adjustment mechanism 2 includes a connecting block 204 slidably connected to the inner wall of the protective frame 1, and a movable frame 201 is fixedly connected to the lower surface of the connecting block 204. The clamping mechanism 3 includes a fixed frame 302 fixedly connected to the outer surface of the movable frame 201, a telescopic frame 303 slidably connected to the inner wall of the fixed frame 302, a lower pressure plate 305 fixedly connected to the lower surface of the telescopic frame 303, and a roller 306 rotatably connected to the lower surface of the lower pressure plate 305.

[0031] Furthermore, a limiting block 309 is fixedly connected to the outer surface of the telescopic frame 303, and the outer surface of the limiting block 309 is slidably connected to the outer surface of the fixed frame 302. A spring 308 is fixedly connected to the inner wall of the fixed frame 302, and the other end of the spring 308 is fixedly connected to the upper surface of the telescopic frame 303. Two sets of gripper blocks 307 are rotatably connected to the outer surface of the fixed frame 302. A hydraulic telescopic rod 301 is hinged to the upper end of the gripper block 307, and the inner wall of the gripper block 307 is fixedly connected to the rubber pad 304.

[0032] In this embodiment, the lower pressure plate 305 is elastically pressurized and limited by the spring 308, the hydraulic telescopic rod 301 adjusts the angle of the gripper block 307, and the rubber pad 304 increases friction. The three work together to firmly clamp pipes of different sizes. The limiting block 309 prevents the telescopic frame 303 from disengaging, and the fixing bolt 205 ensures a firm connection, ensuring stability during the clamping process and preventing the pipes from slipping and getting damaged.

[0033] Reference Figures 1 to 4 In one aspect of this embodiment, a fixing bolt 205 is threadedly connected to the outer surface of the movable frame 201, and the fixing bolt 205 is threadedly connected to the outer surface of the fixed frame 302.

[0034] Furthermore, the adjustment mechanism 2 also includes a geared motor 202 fixedly connected to the outer surface of the protective frame 1. The output shaft of the geared motor 202 is fixedly connected to a bidirectional threaded rod 203. The bidirectional threaded rod 203 is rotatably connected to the inner wall of the protective frame 1, and the outer surface of the bidirectional threaded rod 203 is threadedly connected to the outer surface of the connecting block 204.

[0035] In this embodiment, by using the geared motor 202 to drive the bidirectional threaded rod 203, the distance between the two sets of clamping mechanisms 3 can be adjusted so that they can be accurately clamped in the middle of a long pipe. This middle clamping method can balance the force on the pipe, reduce the shaking caused by the weight distribution at both ends during transportation, significantly increase the stability of the pipe during movement, and further improve transportation safety.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] Working Principle: This device can be fixedly connected to the clamping equipment via the protective frame 1. The clamping equipment's mobility drives the protective frame 1 and the entire clamping device to move. After clamping the pipe, the clamping equipment can move the pipe to achieve positional transfer, thus realizing the clamping and transportation of the pipeline. Based on the length of the oil drilling pipe to be clamped, the reduction motor 202 of the adjusting mechanism 2 is activated. The output shaft of the reduction motor 202 drives the bidirectional threaded rod 203 to rotate. The bidirectional threaded rod 203 drives two sets of connecting blocks 204 to move in opposite directions along the inner wall of the protective frame 1, thereby moving the moving frame 201 and the connected clamping mechanism 3 until the distance between the two sets of clamping mechanisms 3 matches the length of the pipe. Then, the reduction motor 202 is turned off. Next, the pipe is placed between the two sets of clamping mechanisms 3. The pipe will press against the lower pressure plate 305, causing the telescopic frame 303 to slide upwards and press down. The spring 308 is compressed, and its elastic force causes the lower pressure plate 305 to press tightly against the upper surface of the pipe, achieving initial pressure limiting. The limiting block 309 slides on the surface of the fixed frame 302 to prevent the telescopic frame 303 from separating from the fixed frame 302. Then, the hydraulic telescopic rod 301 is activated, and its output end extends to push the two sets of gripper blocks 307 to rotate. The angle of the gripper blocks 307 is adjusted so that their inner walls fit against the outer surface of the pipe. The rubber pad 304 increases the friction with the pipe and enhances the clamping stability. After the gripper blocks 307 firmly clamp the pipe, the hydraulic telescopic rod 301 is closed to complete the clamping operation of the pipe. If it is necessary to remove the pipe, the hydraulic telescopic rod 301 is activated first to shorten its output end, causing the gripper blocks 307 to release the pipe. At the same time, the spring 308 rebounds to reset the lower pressure plate 305, releasing the initial limiting of the pipe. Finally, the pipe can be removed from the gripper.
