Description
Technical Field
[0001] This utility model relates to the field of oil pipe fixing technology, and in particular to an oil pipe clamp. Background Technology
[0002] In tubing processing, installation, and maintenance, stable tubing fixation is crucial for ensuring operational accuracy and safety. Traditional tubing fixing devices often employ simple clamping structures, achieving fixation through bolt tightening or ordinary clamping. However, these devices have several drawbacks. Firstly, the clamping force is difficult to control precisely. Excessive force can damage the tubing surface coating, deform the pipe wall, and even affect the integrity of the internal channels; insufficient force cannot provide adequate fixation, leading to displacement and swaying of the tubing during processing or under stress, reducing operational accuracy, and potentially causing safety accidents. Secondly, the support structure of traditional fixing devices is often a surface contact design, resulting in significant friction between the tubing and the support surface. This makes adjustment of the tubing position or long-distance tubing installation difficult, and the localized stress concentration caused by surface contact can easily scratch the tubing surface. Furthermore, workers cannot visually assess the fixation status and must rely on experience, further increasing operational risks.
[0003] Therefore, it is necessary to provide a new tubing clamp to solve the above-mentioned technical problems. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides an oil pipe clamp.
[0005] The tubing clamp provided by this utility model includes a base, on which two symmetrically distributed side frames are fixedly installed, and a front-to-back support platform is fixedly mounted between the two side frames, with a semi-circular groove opened on each support platform. The base is also equipped with a clamping component, which includes a base plate. The base plate is fixedly installed on the base and located between two support platforms. A hydraulic cylinder is fixedly mounted on the base plate. An upper clamping plate is fixedly installed at the output end of the hydraulic cylinder. A semi-circular cavity is opened at the bottom of the upper clamping plate. The upper clamp plate is equipped with a monitoring component, which includes a bracket. The bracket is fixedly installed on the upper clamp plate, and an installation cylinder is fixedly suspended on the inner top wall of the bracket. A pressure bar and a pressure sensor for detecting the pressure of the pressure bar are installed inside the installation cylinder.
[0006] Preferably, the pressure sensor is fixedly installed on the inner top wall of the mounting cylinder, and a spring is fixedly installed on the pressure detection end of the pressure sensor, with the other end of the spring fixedly connected to the insertion end of the pressure rod.
[0007] Preferably, the pressure rod is slidably connected to the mounting cylinder, and the lower end of the pressure rod extends out of the mounting cylinder and is fitted with a rotatably connected ball bearing.
[0008] Preferably, a control panel is also fixedly installed on the bracket, and the control panel is electrically connected to the pressure sensor.
[0009] Preferably, the semicircular grooves of the two support platforms are coaxially arranged, and each support platform has a number of evenly distributed spherical cavities in its semicircular groove, and each spherical cavity is fitted with a rotating steel ball.
[0010] Preferably, a slide rail is also fixedly installed on the base plate, and two symmetrically distributed T-slots are provided on the slide rail. Two symmetrically distributed side-sliding T-heads are fixedly installed on the side wall opposite to the connection end of the upper clamp plate and the hydraulic cylinder, and the two side-sliding T-heads are respectively inserted into the two T-slots and slidably connected to the T-slots.
[0011] Preferably, a rubber pad is fixedly fitted into the semi-circular cavity at the bottom of the upper clamp plate.
[0012] Compared with related technologies, the tubing clamp provided by this utility model has the following beneficial effects: 1. The hydraulic cylinder of this utility model provides a stable driving force to drive the upper clamping plate to achieve lifting and clamping. With the side sliding T-head and the T-slot of the slide rail sliding connection, the movement trajectory of the upper clamping plate is effectively restricted, avoiding deviation during clamping and greatly improving the stability and accuracy of clamping. Meanwhile, the semi-circular groove of the support platform is embedded with rotating steel balls, which converts the sliding friction between the oil pipe and the support surface into rolling friction, reducing the resistance when the oil pipe moves, and dispersing the contact pressure to avoid scratches or coating damage on the oil pipe surface caused by local stress concentration. 2. The monitoring component set in this utility model realizes real-time monitoring and precise control of clamping force. When the hydraulic cylinder pushes the upper clamping plate to descend and clamp, the ball at the bottom of the pressure rod first contacts the oil pipe. As the upper clamping plate continues to press down, the pressure rod compresses the spring. The pressure sensor detects the deformation pressure of the spring in real time and transmits the data to the control panel. The operator can intuitively grasp the clamping force through the control panel, avoiding oil pipe damage or unstable fixation caused by excessive or insufficient pressure, which significantly improves the safety and reliability of the operation.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0016] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0017] Please see Figures 1 to 5 The present invention provides a tubing clamp, which includes a base 1, a support platform 3, a clamping component 5, and a monitoring component 6.
[0018] In the embodiments of this utility model, please refer to Figures 1 to 5 Two symmetrically distributed side frames 2 are fixedly installed on the base 1, and a support platform 3 distributed in front and behind is fixedly installed between the two side frames 2. Each support platform 3 has a semi-circular groove 3a, and the semi-circular grooves 3a of the two support platforms 3 are coaxially arranged. Each semi-circular groove 3a of each support platform 3 has several evenly distributed spherical cavities, and each spherical cavity is fitted with a rotating steel ball 4. The base 1 is also equipped with a clamping component 5, which includes a base plate 51. The base plate 51 is fixedly installed on the base 1 and located between two support platforms 3. A hydraulic cylinder 53 is fixedly mounted on the base plate 51. An upper clamping plate 52 is fixedly installed at the output end of the hydraulic cylinder 53. A semi-circular cavity is opened at the bottom of the upper clamping plate 52, and a rubber pad 7 is fixedly embedded in the semi-circular cavity opened at the bottom of the upper clamping plate 52.
[0019] It is worth noting that, in use, this application consists of multiple sets arranged side by side (with the semi-circular grooves 3a on the support platform 3 coaxially arranged), thus forming a fixing structure for the caliper during tubing processing. During tubing processing, the tubing head is placed in the semi-circular grooves 3a opened on the two support platforms 3. Depending on the length of the tubing, the tubing body (or the tail section) can be placed in the semi-circular grooves 3a opened on the support platform 3 on the rear base 1 (e.g., Figure 6 (As shown).
[0020] It should be noted that after the oil pipe is positioned, the hydraulic cylinder 53 is activated to drive the upper clamp plate 52 to descend, so that the bottom of the upper clamp plate 52 has a semi-circular cavity to press the oil pipe section between the two support platforms 3. Therefore, the upper clamp plate 52, together with the support platforms 3 on both sides, forms a clamp structure and fixes the oil pipe. The operation is simple and convenient. In addition, the rubber pad 7 set at the bottom of the upper clamp plate 52 can effectively protect the stressed section of the oil pipe.
[0021] It should also be noted that the steel ball 4 is rotatably installed in the semi-circular groove 3a of the support platform 3, which facilitates the oil pipe to travel along the support platform 3 and converts the radial friction of the oil pipe into rolling friction. At the same time, the steel ball 4 forms point contact with the surface of the oil pipe, dispersing the traditional surface contact pressure into multiple point loads, avoiding local stress concentration that could lead to coating damage and scratches on the surface of the oil pipe.
[0022] Furthermore, a slide rail 54 is fixedly installed on the base plate 51, and two symmetrically distributed T-slots 54a are provided on the slide rail 54. Two symmetrically distributed side-sliding T-heads 521 are fixedly installed on the side wall opposite to the connection end of the upper clamp plate 52 and the hydraulic cylinder 53, and the two side-sliding T-heads 521 are respectively inserted into the two T-slots 54a and slidably connected to the T-slots 54a. Side-sliding T-heads 521 are provided on the other side of the upper clamp plate 52, so that when the hydraulic cylinder 53 pushes the upper clamp plate 52 to rise and fall, the side-sliding T-heads 521 and the T-slots 54a provided on the slide rail 54 cooperate with each other, which greatly improves the stability of the upper clamp plate 52 when it rises and falls.
[0023] In the embodiments of this utility model, please refer to Figures 1 to 5A monitoring component 6 is installed on the upper clamp plate 52, and the monitoring component 6 includes a bracket 61. The bracket 61 is fixedly installed on the upper clamp plate 52, and an installation cylinder 62 is fixedly suspended on the inner top wall of the bracket 61. A pressure rod 64 and a pressure sensor 63 for detecting the pressure of the pressure rod 64 are installed inside the installation cylinder 62. Specifically, the pressure sensor 63 is fixedly installed on the inner top wall of the installation cylinder 62, and a spring 65 is fixedly installed at the pressure detection end of the pressure sensor 63. The other end of the spring 65 is fixedly connected to the insertion end of the pressure rod 64. The pressure rod 64 is slidably connected to the installation cylinder 62, and the lower rod head of the pressure rod 64 extends out of the installation cylinder 62 and is fitted with a rotatably connected ball bearing 66. A control panel 67 is also fixedly installed on the bracket 61, and the control panel 67 is electrically connected to the pressure sensor 63.
[0024] It should be noted that when the hydraulic cylinder 53 is activated and the upper clamp plate 52 is lowered, the ball bearing 66 at the bottom of the pressure rod 64 is in pre-contact with the upper surface of the oil pipe. As the upper clamp plate 52 presses against the oil pipe, the pressure rod 64 slides along the inside of the mounting cylinder 62 and compresses the spring 65. Therefore, the pressure sensor 63 can detect the pressing force of the upper clamp plate 52 on the oil pipe and transmit the data to the control panel 67. The operator can intuitively grasp the clamping force through the control panel 67, avoiding oil pipe damage or unstable fixation caused by excessive or insufficient pressure, which significantly improves the safety and reliability of the operation.
[0025] The working principle of the tubing clamp provided by this utility model is as follows: The base 1, side frame 2, and support platform 3 form a stable support foundation. The semi-circular grooves 3a of the two support platforms 3 are coaxially arranged, which can accurately position the oil pipe. The hydraulic cylinder 53 provides a stable driving force to drive the upper clamping plate 52 to achieve lifting and clamping. With the sliding T-head 521 and the T-slot 54a of the slide rail 54 slidingly connected, the movement trajectory of the upper clamping plate 52 is effectively restricted, avoiding deviation during clamping and greatly improving the stability and accuracy of clamping. The semi-circular grooves 3a of the support platform 3 are embedded with rotating steel balls 4, which convert the sliding friction between the oil pipe and the support surface into rolling friction, reducing the resistance when the oil pipe moves, and dispersing the contact pressure to avoid scratches or coating damage to the oil pipe surface caused by local stress concentration. Damage; The rubber pad 7 fixedly fitted in the semi-circular cavity at the bottom of the upper clamping plate 52 can play a buffering role during clamping, further protecting the surface of the oil pipe from damage. The monitoring component 6 realizes real-time monitoring and precise control of the clamping force. When the hydraulic cylinder 53 pushes the upper clamping plate 52 down to clamp, the ball 66 at the bottom of the pressure rod 64 first contacts the oil pipe. As the upper clamping plate 52 continues to press down, the pressure rod 64 compresses the spring 65. The pressure sensor 63 detects the deformation pressure of the spring 65 in real time and transmits the data to the control panel 67. The operator can intuitively grasp the clamping force through the control panel 67, avoiding oil pipe damage or unstable fixation caused by excessive or insufficient pressure, which significantly improves the safety and reliability of the operation.
[0026] The hydraulic cylinder 53 of this utility model is connected to a standard hydraulic system through an external pipeline to achieve its extension and retraction control (the hydraulic cylinder 53 obtains power through an external hydraulic pump station connected to a pipeline, and switches the flow direction of hydraulic oil by operating the reversing valve on the pipeline, thereby controlling the extension or retraction of the hydraulic cylinder 53). The specific settings of this hydraulic system are conventional technology in this field. In addition, the circuit and control involved in the pressure sensor 63 in this utility model are all existing technologies, and will not be described in detail here.
[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
