Description

Technical Field

[0001] This utility model relates to the field of pipe positioning clamp technology, and in particular to a pipe positioning clamp with scale markings. Background Technology

[0002] In the field of pipeline engineering, pipe positioning clamps are key devices used to fix, support and position pipelines. Their core function is to stably constrain the pipeline in a preset position (such as a wall, bracket, ground or equipment frame) to prevent the pipeline from shifting, shaking or falling off due to its own weight, medium flow pressure, vibration or changes in ambient temperature, thereby ensuring the installation accuracy, operational safety and service life of the pipeline system.

[0003] Existing pipe positioning clamps primarily rely on bolt tightening to secure pipes, lacking intuitive spacing markings for reference. This makes adjusting pipe positions extremely cumbersome, requiring operators to repeatedly measure the distance between pipes with a tape measure. Each adjustment necessitates loosening bolts, moving the clamps, and re-measuring and calibrating. Even slight deviations require repetition, making the entire process time-consuming and labor-intensive. This not only slows down installation but also easily leads to bolt loosening due to repeated adjustments, affecting stability. More importantly, the difficulty in controlling errors during manual operation results in significant deviations in pipe spacing, leading to a chaotic pipe arrangement. When the spacing is too close, vibrations from the flowing medium cause continuous friction and collisions between adjacent pipes, accelerating wear on the pipe walls and severely impacting their lifespan. Conversely, excessive spacing results in loose pipe distribution on supports, increasing the load on the supports and potentially causing deformation due to uneven stress, jeopardizing the stability of the entire pipeline system. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned above in the background art by proposing a pipe positioning clamp with scale markings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a pipe positioning clamp with graduated markings, comprising a U-shaped support frame, wherein mounting plates are fixedly installed on the surfaces of both vertical ends of the U-shaped support frame, and mounting holes are provided on the surfaces of both mounting plates. A marking device is provided between the inner walls of the two vertical ends of the U-shaped support frame, wherein the marking device comprises a threaded rod rotatably connected between the inner walls of the two vertical ends of the U-shaped support frame, and a rotating wheel is fixedly installed on the outer wall surface of the threaded rod, wherein the threads on the surface of the threaded rod are mutually opposite threads with the rotating wheel as the center.

[0006] Preferably, a sliding rod is fixedly installed between the inner walls of the vertical ends on both sides of the U-shaped support frame, and two sliding plates are threadedly connected to the surface of the threaded rod, with the sliding plates slidably connected by the threaded rod and the sliding rod.

[0007] Preferably, a vertical strip is fixedly installed on one side surface of the slide plate, a round rod is fixedly installed on the surface of the vertical strip, a first clamping ring is fixedly installed at the end of the round rod away from the vertical strip, and a second clamping ring is slidably connected to the outer wall surface of the round rod.

[0008] Preferably, a sleeve is fixedly installed on the surface of the vertical strip, and a push rod is slidably connected inside the sleeve. The end of the push rod away from the sleeve is fixedly connected to a second clamping ring.

[0009] Preferably, a spring is fixedly installed on the surface of the sleeve away from the vertical strip, and the end of the spring away from the sleeve is fixedly connected to the second clamping ring.

[0010] Preferably, a scale line is fixedly installed on one side surface of the horizontal end of the U-shaped support frame.

[0011] The aforementioned components achieve the following effects: by utilizing the cooperation of the threaded rod and the reverse thread, the slide plate can be moved smoothly along the slide rod, and the positions of the clamping rings on both sides can be adjusted simultaneously. With the help of the scale lines on the U-shaped support frame, the pipe spacing can be read intuitively without the need for repeated measurement with a tape measure, greatly simplifying the adjustment process, ensuring accurate and consistent pipe spacing, and avoiding the problem of disordered arrangement caused by manual operation errors.

[0012] Preferably, the top surface of the first clamping ring is provided with a reinforcing device, the reinforcing device including a fixing plate fixedly installed on the top surface of the first clamping ring, and the surface of the fixing plate is threaded with bolts.

[0013] Preferably, a positioning plate is fixedly installed on the top surface of the second clamping ring, and the surface of the positioning plate has threaded holes that match the bolts.

[0014] The effect achieved by the above components is as follows: through the cooperation of bolts and threaded holes, the fastening force on the pipeline is further enhanced on the basis of elastic clamping, which can effectively resist the external forces generated by vibration, gravity or medium flow of the pipeline, prevent loosening after long-term use, and ensure that the pipeline is always stably fixed in the preset position.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting an marking device, the sliding plate can be moved smoothly along the sliding rod by the cooperation of the threaded rod and the reverse thread, and the position of the clamping rings on both sides can be adjusted simultaneously. With the scale lines on the U-shaped support frame, the pipe spacing can be read intuitively without the need for repeated measurement with a tape measure, which greatly simplifies the adjustment process, ensures that the pipe spacing is accurate and consistent, and avoids the problem of messy arrangement caused by manual operation errors. At the same time, the spring-driven second clamping ring forms an elastic clamping structure, and the guiding action of the top rod and the sleeve ensures that the clamping ring is aligned and fits, which not only avoids damage to the pipe due to excessive clamping, but also prevents loosening and displacement, thereby improving the stability and adaptability of pipe fixing.

[0018] Example 1, such as Figure 1-4 As shown, a pipe positioning clamp with scale markings includes a U-shaped support frame 1. Mounting plates 4 are fixedly installed on the surfaces of the vertical ends of both sides of the U-shaped support frame 1, and mounting holes are opened on the surfaces of the two mounting plates 4.

[0019] Reference Figure 1-3As shown in this embodiment: an marking device 2 is provided between the inner walls of the vertical ends of the U-shaped support frame 1. The marking device 2 includes a threaded rod 201 rotatably connected between the inner walls of the vertical ends of the U-shaped support frame 1. A rotating wheel 202 is fixedly installed on the outer surface of the threaded rod 201. The threads on the surface of the threaded rod 201 are mutually opposite threads with the rotating wheel 202 as the center. A sliding rod 203 is fixedly installed between the inner walls of the vertical ends of the U-shaped support frame 1. Two sliding plates 204 are threadedly connected to the surface of the threaded rod 201. The sliding plates 204 are slidably connected by the threaded rod 201 and the sliding rod 203. A vertical strip plate 205 is fixedly installed on one side surface of the sliding plate 204. A round rod 206 is fixedly installed on the surface of the vertical plate 205. A first clamping ring 207 is fixedly installed at the end of the round rod 206 away from the vertical plate 205. A second clamping ring 208 is slidably connected to the outer surface of the round rod 206. A sleeve 209 is fixedly installed on the surface of the vertical plate 205. An internal sliding connection includes a push rod 210, with the end of the push rod 210 away from the sleeve 209 fixedly connected to the second clamping ring 208. A spring 211 is fixedly installed on the surface of the end of the sleeve 209 away from the vertical strip 205, with the end of the spring 211 away from the sleeve 209 fixedly connected to the second clamping ring 208. A scale line 212 is fixedly installed on one side of the horizontal end of the U-shaped support frame 1. The threaded rod 201 has a pitch of 3mm, a diameter of 16mm, and is chrome-plated for rust prevention. The scale line 212... 12. The minimum scale is 1mm, the range is 0-500mm, the accuracy is ±0.1mm, the slide plate 204 is made of polytetrafluoroethylene, the semi-circular arc of the first clamping ring 207 is 180°, the inner diameter is 50-200mm, and the inner wall is covered with a rubber pad to prevent scratches. The second clamping ring 208 is symmetrical to the first clamping ring 207, and the gap between the two is ≤0.2mm. The diameter of the spring 211 is 15mm, the free length is 50mm, and the elastic force is 80-150N when the compression is 5-15mm.

[0020] Reference Figure 3-4 As shown in this embodiment: the top surface of the first clamping ring 207 is provided with a reinforcing device 3, the reinforcing device 3 includes a fixing plate 31 fixedly installed on the top surface of the first clamping ring 207, the surface of the fixing plate 31 is threaded with a bolt 32, the top surface of the second clamping ring 208 is fixedly installed with a positioning plate 33, the surface of the positioning plate 33 is provided with a threaded hole 34 that matches the bolt 32.

[0021] Working principle: When using this device, first check the condition of each component: confirm that the threaded rod 201 rotates smoothly, the spring 211 has good elasticity without breakage or excessive looseness, the scale line 212 is clear and without wear, and the rubber pad on the inner wall of the first clamping ring 207 is intact. Then, fix the U-shaped support frame 1 to the preset bracket or wall through the mounting holes of the mounting plate 4, ensuring that the overall installation is firm and without shaking. After the inspection is completed, the operator first pushes the two second clamping rings 208 simultaneously by hand, so that they slide away from the first clamping ring 207 along the round rod 206. When the second clamping rings 208 move, they simultaneously drive the top rod 210 to slide into the sleeve 209, and at the same time squeeze the spring 211 to compress it. The amount of compression is adjusted according to the pipe diameter. First, ensure the pipe can be smoothly inserted. Then, gently place the pipe to be fixed between the first clamping ring 207 and the second clamping ring 208, ensuring the outer wall of the pipe is in contact with the rubber pad of the first clamping ring 207. Release the hand pushing the second clamping ring 208; the spring 211, with its rebound force, pushes the second clamping ring 208 back to its original position, working in conjunction with the first clamping ring 207 to elastically clamp the pipe. The rubber pad prevents excessive clamping and damage to the outer wall of the pipe. After the pipe is initially clamped, use a tool to rotate the bolt 32 on the fixing plate 31, gradually screwing the bolt 32 into the threaded hole 34 of the positioning plate 33 until the bolt 32 is tightened to the preset state, ensuring the clamping force of the first clamping ring 207 and the second clamping ring 208 on the pipe is stable, further reinforcing the pipe. To prevent loosening or displacement under vibration, when adjusting the distance between two pipes, first observe the reading of the scale line 212 aligned with the edge of the slide plate 204, record the current distance, and then rotate the rotating wheel 202. The rotating wheel 202 drives the threaded rod 201 to rotate synchronously. Since the threads on the surface of the threaded rod 201 are opposite to each other with the rotating wheel 202 as the center, the two slide plates 204 connected by their surface threads will slide along the slide rod 203 in the direction of moving closer or further away from each other. The slide rod 203 can prevent the slide plate 202 from shaking and ensure smooth movement. When the slide plate 204 moves, it drives the first clamping ring 207, the second clamping ring 208 and the clamped pipe to move synchronously through the vertical bar plate 205. The operator observes the slide plate in real time. Rotate the wheel 202 until the target spacing is reached, corresponding to the scale line 212 on the edge of plate 202. Stop rotating the wheel 202. At this point, the spacing between the two pipes has been precisely adjusted according to the scale. After each use, clean the dust or impurities on the surface of the threaded rod 201 and slide rod 203 to avoid affecting the smoothness of sliding. Regularly check the elasticity of spring 211. If the elasticity is insufficient and the pipe cannot be effectively clamped, it should be replaced in time. Calibrate the accuracy of the scale line 212 every quarter to ensure the accuracy of the spacing adjustment. Through the above process, the device uses the elastic clamping structure to achieve stable pipe fixation. Combined with the scale markings and threaded rod adjustment, it solves the problems of cumbersome and low-precision traditional pipe clamp spacing adjustment, ensuring neat pipe arrangement and improving installation efficiency and system stability.
