Description

Technical Field

[0001] This utility model belongs to the field of pipeline construction technology, specifically a pipe wall roughening device. Background Technology

[0002] When constructing a pipeline, it is necessary to first conduct surveying and layout, then excavate the foundation pit, distribute the pipelines, connect the pipelines, pressure test the pipelines to ensure normal use, and finally backfill.

[0003] When connecting pipes, different connection methods are used depending on the material. Concrete pipes need to be sealed with cement, high-polymer PE pipes are often sealed by socket or hot-melt, and PVC pipes are generally connected by adhesive.

[0004] To ensure the effectiveness of the adhesive, the joint needs to be cleaned and roughened before bonding the pipes. Roughening refers to roughening the pipe joint, which can enhance the stability and sealing of the connection, prevent water leakage, make the joint more secure, and prevent breakage or loosening. At the same time, roughening can also improve the curing effect of the pipe adhesive.

[0005] Existing roughening methods typically involve workers using files to grind the pipe joints to achieve a roughening effect. However, this method has drawbacks, as it cannot guarantee uniform application of the file to the pipe openings, resulting in inconsistent depths. Consequently, this can lead to inconsistent gaps at the pipe connections. Therefore, based on existing methods, a structure is designed that can uniformly roughen pipes while ensuring the ease of use of the device, thereby improving work efficiency. Utility Model Content

[0006] The purpose of this utility model is to provide a pipe wall roughening device in order to solve the above-mentioned problems.

[0007] The technical solution adopted by this utility model is as follows: a pipe wall roughening device, including a positioning column, a threaded hole is embedded in the center of one end of the positioning column, guide columns A are symmetrically arranged on the outer wall of the positioning column, oblique teeth are arranged in parallel inside the guide columns A, and a support component that can be connected to the inner wall of the pipe is provided on the outside of the positioning column.

[0008] The support components include: top plate, support frame A, support frame B, sliding sleeve, and ball bearings;

[0009] The positioning post and the guide post A are slidably connected by a sliding sleeve. A cavity is symmetrically arranged on one side of the sliding sleeve. A ball is movably connected inside the cavity by a spring. A support frame A is rotatably connected to the outer wall of the sliding sleeve. A support frame B is rotatably connected to the outer wall of the other side of the positioning post. A top plate is rotatably connected to the other end of the support frame A and the support frame B.

[0010] A roughening component capable of roughening the outer wall of the pipe is installed on one side of the positioning column;

[0011] The roughening assembly includes: a U-shaped frame, a long lead screw, a protrusion, a mounting plate, a short lead screw, guide post B, and a file.

[0012] A U-shaped frame is movably connected to the external positioning column. A long lead screw is integrally provided at one end of the U-shaped frame, and a protrusion is integrally provided at the other end of the U-shaped frame. A mounting plate is provided below the protrusion. Guide columns B are symmetrically arranged on the back of the mounting plate. A short lead screw is rotatably connected to the back of the mounting plate between the two guide columns B. A file is installed on the front of the mounting plate by bolts. The short lead screw and the guide columns B both extend through the protrusion, and the short lead screw is threadedly connected to the protrusion. The guide columns B are slidably connected to the protrusion.

[0013] Among them, the support frame A and support frame B have the same length, and there are at least three sets of top plate, support frame A and support frame B.

[0014] The long lead screw is threadedly engaged with the threaded hole.

[0015] The top plate has an arc-shaped contact surface with the pipe and is fitted with a rubber layer.

[0016] The bottom of the ball is provided with oblique teeth that engage with the oblique teeth, providing a one-way connection.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] 1. In this utility model, the support component ensures that the center of the positioning column and the center of the pipe are on the same straight line. Then, by rotating the U-shaped frame, the spiral motion generated by the engagement of the long screw and the threaded hole can drive the file plate to perform spiral motion on the outer wall of the pipe. By utilizing the translational and rotational coupling characteristics of the spiral motion, the outer wall of the pipe is roughened along a spiral path, ensuring the consistency of the roughening depth at the pipe opening. At the same time, the file plate can be adjusted according to the usage requirements, ensuring the practicality of the device.

[0019] 2. In this utility model, by extending the support frame A and the support frame B, the top plate can be extended synchronously and supported between the top plate and the inner wall of the pipe. The contact surface between the top plate and the pipe is arc-shaped and has a rubber layer attached. The rubber layer can increase the friction between the top plate and the pipe, further improving stability, making the entire device easy to install and disassemble, and improving the work progress.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In this utility model:

[0029] Reference Figure 1-6 A pipe wall roughening device includes a positioning column 1, a threaded hole 101 is embedded in the center of one end of the positioning column 1, guide columns A102 are symmetrically arranged on the outer wall of the positioning column 1, helical teeth 1021 are arranged in parallel inside the guide columns A102, and a support component that can be connected to the inner wall of the pipe is provided on the outside of the positioning column 1.

[0030] The support components include: top plate 2, support frame A201, support frame B202, sliding sleeve 6, and ball 601;

[0031] A sliding sleeve 6 is slidably connected to the positioning column 1 and the guide column A102. A cavity is symmetrically arranged on one side of the sliding sleeve 6. A ball 601 is movably connected inside the cavity through a spring. A support frame A201 is rotatably connected to the outer wall of the sliding sleeve 6. A support frame B202 is rotatably connected to the outer wall of the positioning column 1 on the other side. The other ends of the support frames A201 and B202 are rotatably connected to the top plate 2. The support frames A201 and B202 have the same length, and there are at least three sets of the top plate 2, support frames A201 and B202. This arrangement allows the support frames A201 and B202 to retract or extend when the sliding sleeve 6 moves outside the positioning column 1, which in turn causes the top plate 2 to retract or extend, providing support between the top plate 2 and the inner wall of the pipe. The contact surface between the top plate 2 and the pipe is arc-shaped and has a rubber layer attached. The rubber layer increases the friction between the top plate 2 and the pipe contact surface, further improving stability.

[0032] A roughening component is installed on one side of the positioning column 1 to roughen the outer wall of the pipe;

[0033] The roughening assembly includes: a U-shaped frame 3, a long lead screw 301, a protrusion 302, a mounting plate 4, a short lead screw 401, a guide post B402, and a file 5;

[0034] The positioning post 1 is externally connected to a U-shaped frame 3. One end of the U-shaped frame 3 is integrally equipped with a long lead screw 301, and the other end is integrally equipped with a protrusion 302. A mounting plate 4 is positioned below the protrusion 302. Guide posts B402 are symmetrically arranged on the back of the mounting plate 4. A short lead screw 401 is rotatably connected to the back of the mounting plate 4 between the two guide posts B402. A file 5 is bolted to the front of the mounting plate 4. Both the short lead screw 401 and the guide posts B402 extend through the protrusion 301. 2. The short lead screw 401 is threadedly connected to the protrusion 302, and the guide post B402 is slidably connected to the protrusion 302. By rotating the short lead screw 401, the thread engagement with the guide post B402 guides the mounting plate 4 to move the file 5 downward and make contact with the outer wall of the pipe. By rotating the U-shaped frame 3, the long lead screw 301 engages with the threaded hole 101 and moves, and drives the mounting plate 4 to make the file 5 perform a spiral motion on the outer wall of the pipe to roughen the outer wall of the pipe.

[0035] Furthermore, the long lead screw 301 engages with the threaded hole 101. The spiral motion generated by the engagement of the long lead screw 301 and the threaded hole 101 can drive the file 5 to perform spiral motion on the outer wall of the pipe. By utilizing the translational and rotational coupling characteristics of the spiral motion, the outer wall of the pipe is roughened in a spiral path.

[0036] Furthermore, the bottom of the ball 601 is provided with oblique teeth that engage with the oblique teeth 1021, providing a one-way connection. This design allows the operator to place the top plate 2 into the pipe and simultaneously push the sliding sleeve 6 to make the oblique teeth 1021 engage in a one-way manner, locking the position of the sliding sleeve 6 and achieving the purpose of supporting and positioning the positioning column 1, ensuring that the axis of the positioning column 1 and the axis of the pipe are on the same straight line.

[0037] Furthermore, the long lead screw 301, the short lead screw 401, and the U-shaped frame 3 are all made of high-strength steel, and reinforcing ribs are provided between the U-shaped frames 3 to provide better support. At the same time, the threads of the long lead screw 301 and the short lead screw 401 are high-density threads, which can achieve better relaxation.

[0038] Furthermore, the bottom of the file plate 5 is provided with several file-shaped protrusions.

[0039] Working principle: First, the top plate 2 is placed into the pipe. Simultaneously, pushing the sliding sleeve 6 causes the helical teeth 1021 to engage in a one-way manner, locking the position of the sliding sleeve 6. At the same time, the support frame A201 and support frame B202 extend, which in turn causes the top plate 2 to extend synchronously, providing support between itself and the inner wall of the pipe. The contact surface between the top plate 2 and the pipe is arc-shaped and has a rubber layer attached. The rubber layer increases the friction between the top plate 2 and the pipe contact surface, further improving stability and achieving the purpose of supporting and positioning the positioning column 1. This ensures that the axis of the positioning column 1 and the axis of the pipe are aligned in a straight line. Then, depending on the depth of the roughening, the short screw is rotated... 401 utilizes the engagement of the threaded engagement with the guide post B402 to guide the mounting plate 4 to move the file 5 downwards, making contact with the outer wall of the pipe. Then, by rotating the U-shaped frame 3, the long screw 301 engages with the threaded hole 101 to move. The spiral motion generated by the engagement of the long screw 301 with the threaded hole 101 can drive the file 5 to perform spiral motion on the outer wall of the pipe. Utilizing the translational and rotational coupling characteristics of the spiral motion, the outer wall of the pipe is roughened in a spiral path. After the operation is completed, the oblique tooth restriction is released by pulling the outer ball 601. Similarly, the top plate 2 is removed by the linkage retraction of the support frame A201 and support frame B202.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
