Description

Technical Field

[0001] This application relates to the field of underground pipeline construction technology, specifically to an underground pipeline pipe-laying auxiliary device. Background Technology

[0002] One of the challenges in underground pipeline construction is how to guide large-diameter heating pipelines through existing structures such as roads and canals. Currently, the common construction method involves laying the heating pipeline through pre-installed underground sleeves. The main methods for laying heating pipelines are pipe pulling and pipe jacking, with multiple specially designed rolling supports fixed to the pipeline to assist in the installation. Existing rolling supports often use rollers to reduce pipeline resistance. However, because underground pipelines frequently have curves or bends, and rollers can only rotate in one direction, the resistance from the rollers is significant when the pipeline turns, making the pipeline prone to jamming. Utility Model Content

[0003] To address the aforementioned technical problems, this application provides an underground pipeline installation auxiliary device for laying the pipeline to be installed within a pre-set sleeve. The device includes two support components, each comprising a support semi-ring and at least two universal bearings. The support semi-ring has a semi-circular cross-section, and the two support semi-rings are interconnected to secure the pipeline. Each support semi-ring has at least two circumferences along its axial direction, and each circumference is provided with at least one universal bearing. The universal bearings on adjacent circumferences are interleaved. Each universal bearing includes a bearing base and a rolling ball. The bearing base is fixedly connected to the outer wall of the support semi-ring, and the rolling ball is housed in the bearing base and rotatably connected to it. A portion of the rolling ball protrudes from the bearing base and contacts the pre-set sleeve. Because multiple universal bearings are arranged in multiple rows along the entire outer wall of the pipeline to be installed, the universal bearings can effectively provide support regardless of the direction in which the pipeline moves, preventing jamming.

[0004] Preferably, the supporting semi-ring has two arrangement circumferences, and three universal bearings are spaced apart along the circumferential direction of each arrangement circumference. The included angle between the projections of each universal bearing on the cross-section of the supporting semi-ring is 30°, so that no matter which direction the pipe to be installed moves, two universal bearings are in contact with the preset sleeve, thereby better supporting the pipe to be installed.

[0005] In some embodiments, the universal bearing further includes a plurality of bearing balls and a ball holder housed within the bearing base. The ball holder has a groove concentric with the rolling balls, and the bearing balls are housed in the groove and abut against the rolling balls. Thus, the relative movement between the rolling balls and the bearing base and the ball holder is rolling, which effectively reduces friction and reduces wear on the rolling balls.

[0006] In some embodiments, the universal bearing further includes a buffer spring. The ball bearing bracket is slidably connected to the bearing base, and one end of the buffer spring is connected to the ball bearing bracket, while the other end is connected to the bearing base. During the movement of the pipe to be installed, vibration loads may occur. The buffer spring can effectively mitigate the impact of these vibration loads on the bearing balls and the pipe to be installed, protecting the pipe and improving the service life of the universal bearing.

[0007] In some embodiments, the rolling ball is made of nylon. Nylon is relatively soft, which can effectively protect the pre-set sleeve, buffer impact, and its smoothness can reduce friction.

[0008] In some embodiments, the two ends of the two supporting semi-rings are respectively connected by bolts.

[0009] In some embodiments, one end of the two supporting semi-rings is hinged and the other end is bolted together.

[0010] In some embodiments, the support assembly further includes a buffer pad, one side of which contacts the inner side of the support semi-ring, and the other side contacts the pipe to be installed. The buffer pad effectively buffers impact loads and protects the pipe to be installed.

[0011] In some embodiments, the support assembly further includes at least one traction connector fixed to the outside of the support semi-ring, the traction connector being used to connect a pipe traction device. When using the traction method to install the pipe, it is unnecessary to install additional traction connection equipment, which can reduce construction costs and improve construction efficiency.

[0012] Specifically, the traction connector includes a circular ring and a connecting part. One end of the connecting part is fixedly connected to the outside of the supporting half-ring, and the other end is fixedly connected to the circular ring. The traction device can bind the traction wire rope to the circular ring to pull the pipe to be installed.

[0013] The beneficial effects of this application are as follows: This application provides an underground pipeline installation auxiliary device for laying the pipeline to be installed within a pre-set sleeve. It includes two support components, each comprising a support semi-ring and at least two universal bearings. The support semi-ring has a semi-circular cross-section. The two support semi-rings are connected to each other to clamp the pipeline to be installed. The support semi-ring has at least two circumferences along the axial direction, and each circumference is provided with at least one universal bearing. The universal bearings on adjacent circumferences are distributed crosswise. Each universal bearing includes a bearing base and a rolling ball. The bearing base is fixedly connected to the outer wall of the support semi-ring, and the rolling ball is housed in the bearing base and rotatably connected to it. A portion of the rolling ball protrudes from the bearing base and contacts the pre-set sleeve. Because multiple universal bearings are arranged in multiple rows along the entire outer wall of the pipeline to be installed, the universal bearings can effectively provide support regardless of the direction in which the pipeline moves, preventing jamming.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other alternative implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Figure 1 and Figure 2This application illustrates a pipe-laying auxiliary device for underground pipelines according to a first embodiment of the present application. The device is used to lay a pipe 200 to be installed within a pre-set sleeve 100. It includes two support components 1, each comprising a support semi-ring 11 and at least two universal bearings 12. The support semi-ring 11 has a semi-circular cross-section. The two support semi-rings 11 are interconnected to clamp the pipe 200 to be installed. The support semi-ring 11 has at least two circumferences 111 along the axial direction. Each circumference 111 is provided with at least one universal bearing 12. The universal bearings 12 on adjacent circumferences 111 are interleaved. Each universal bearing 12 includes a bearing base 121 and a rolling ball 122. The bearing base 121 is fixedly connected to the outer wall of the support semi-ring 11. The rolling ball 122 is housed in the bearing base 121 and rotatably connected to it. Part of the rolling ball 122 protrudes from the bearing base 121 and contacts the pre-set sleeve 100. Because multiple universal bearings 12 are arranged in multiple rows along the entire outer wall of the pipe to be installed 200, the universal bearings 12 can effectively provide support regardless of which direction the pipe to be installed 200 moves, thus avoiding jamming.

[0021] Preferably, in the first embodiment, the supporting semi-ring 11 has two circumferential rings 111, and three universal bearings 12 are spaced apart along the circumferential direction of each circumferential ring 111. The included angle α between the projections of each universal bearing 12 on the cross-section of the supporting semi-ring 11 is 30°. Regardless of the direction in which the pipe 200 to be installed moves, two universal bearings 12 are in contact with the preset sleeve 100, thereby better supporting the pipe 200 to be installed.

[0022] In the first embodiment, as Figure 3 As shown, the universal bearing 12 also includes a plurality of bearing balls 123 housed in the bearing base 121 and a ball bracket 124. The ball bracket 124 has a groove 1241 concentric with the rolling ball 122. The bearing balls 123 are housed in the groove 1241 and abut against the rolling ball 122. Thus, the relative movement between the rolling ball 122 and the bearing base 121 and the ball bracket 124 is rolling, which effectively reduces friction and reduces the wear of the rolling ball 122.

[0023] Furthermore, such as Figure 3 As shown, a buffer spring 125 can also be installed inside the universal bearing 12. The ball bearing bracket 124 is slidably connected to the bearing base 121. One end of the buffer spring 125 is connected to the ball bearing bracket 124, and the other end is connected to the bearing base 121. During the movement of the pipe 200, vibration loads may occur. The buffer spring 125 can effectively mitigate the impact of vibration loads on the bearing balls 123 and the pipe 200, protecting the pipe 200 and improving the service life of the universal bearing 12.

[0024] The rolling ball 122 can be made of various materials, including stainless steel, bearing steel, and nylon. In the first embodiment, nylon is preferred. Nylon is relatively soft, which can effectively protect the pre-set sleeve 100 and buffer impact forces. In addition, the smoothness of nylon can reduce friction.

[0025] There are multiple ways to connect the two supporting semi-rings 11 in this application. In the first embodiment of this application, for example... Figure 1 As shown, the two ends of the two support components 1 are connected together by bolts 2. In the second embodiment of this application, as... Figure 4 As shown, one end of the two support components 1 is connected by bolts 2, and the other end is connected together by hinges 3.

[0026] The two supporting semi-rings 11 can also be hinged at one end and pressed together at the other end by using a quick-release wrench.

[0027] In the second embodiment of this application, as Figure 4 As shown, the support assembly 1 also includes a buffer pad 13, one side of which contacts the inner side of the support semi-ring 11, and the other side contacts the pipe 200 to be installed. The buffer pad 13 can effectively buffer impact loads and protect the pipe 200 to be installed.

[0028] As a further improvement of the second embodiment, the support assembly 1 also includes at least one traction connector 14, which is fixed to the outside of the support semi-ring 11 and is used to connect the pipe traction device. When using the traction method to install the pipe 200, it is not necessary to install additional traction connection equipment, which can reduce construction costs and improve construction efficiency.

[0029] Specifically, such as Figure 4 As shown, two traction connectors 14 are arranged along the circumference of the supporting semi-ring 11.

[0030] The traction connector 14 can have various structural forms, such as a lifting ring, a waist-shaped buckle, or a hook, etc. In the second embodiment, for example... Figure 4 As shown, the traction connector 14 includes a circular ring portion 141 and a connecting portion 142. One end of the connecting portion 142 is fixedly connected to the outer side of the supporting half-ring 11, and the other end is fixedly connected to the circular ring portion 141. The traction device can bind the traction wire rope to the circular ring portion 141, thereby tractioning the pipe 200 to be installed.

[0031] In actual use, multiple underground pipe threading auxiliary devices provided in this application can be installed along the axial direction of the pipe to be installed 200 to better support the pipe to be installed 200 and prevent the pipe to be installed 200 from deforming due to its own weight and contacting the pre-set sleeve 100.

[0032] Finally, it should be noted that if any directional indication (such as up, down, left, right, front, back, etc.) is involved in the embodiments of this application, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0033] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0034] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
