[0001] This utility model relates to the field of pipeline support technology, and in particular to a wear-resistant pipeline support device for mining. Background Technology

[0002] Pipeline systems play a crucial role in mining operations, transporting various media such as slurries, ores, and water. However, due to the complex and harsh mining environment, the support and protection of pipelines face numerous severe challenges.

[0003] Traditional pipe support devices have a simple structure and are usually fixed in design, lacking flexibility. In mining sites, the working scenarios are varied. Sometimes it is necessary to leave passage space for pedestrians on both sides, and sometimes it is necessary to deal with narrow roads so that passage is possible in the middle. However, traditional pipe support devices cannot be flexibly adjusted according to different scenarios, making it difficult to meet the actual working needs. Utility Model Content

[0017] Example 1

[0018] like Figures 1-3As shown in the figure, the wear-resistant pipe support device for mining proposed in this embodiment includes a clamp 1 and a support frame assembly.

[0019] The support frame assembly includes a support base 2, two first rotating rods 3, two second rotating rods 4, two first telescopic rod assemblies, two second telescopic rod assemblies, and two third telescopic rod assemblies. The two first rotating rods 3 are rotatably mounted on the bottom end of the support base 2. The support base 2 and the two first rotating rods 3 are connected via first telescopic rod assemblies. Each first telescopic rod assembly includes a third sleeve 131 and a third movable rod 132. The third sleeve 131 and the third movable rod 132 are rotatably connected to the support base 2 and the first rotating rods 3, respectively. The end of the third movable rod 132 is slidably mounted inside the third sleeve 131. Multiple third limiting grooves are provided on the third movable rod 132. A third wing bolt is threaded onto the third sleeve 131. The two second rotating rods 4 are rotatably connected to the two first rotating rods 3, respectively. The first rotating rods 3 and second rotating rods 4 on corresponding sides are connected via second telescopic rod assemblies. The telescopic rod assembly includes a second sleeve 71 and a second movable rod 72. The second sleeve 71 and the second movable rod 72 are rotatably connected to the first rotating rod 3 and the second rotating rod 4, respectively. The end of the second movable rod 72 is slidably installed inside the second sleeve 71. The second movable rod 72 has multiple second limiting grooves. The second sleeve 71 is threaded with a second wing bolt. Two third telescopic rod assemblies are respectively connected to the bottom ends of the two second rotating rods 4. The third telescopic rod assembly includes a first sleeve 61 and a first movable rod 62. The first sleeve 61 and the first movable rod 62 are respectively connected to the second rotating rod 4 and the fixed base 8. The end of the first movable rod 62 is slidably installed inside the first sleeve 61. The first movable rod 62 has multiple first limiting grooves. The first sleeve 61 is threaded with a first wing bolt. The bottom ends of the two third telescopic rod assemblies are each equipped with a fixed base 8. The clamp 1 is installed above the support base 2.

[0020] The working principle of this technical solution is as follows:

[0021] When it is necessary to facilitate pedestrian passage on both sides of the mine site, the support frame assembly needs to be adjusted to a vertical support state. The operator first loosens the wing bolts on the first, second, and third telescopic rod assemblies. Taking the first telescopic rod assembly as an example, after loosening the third wing bolt on the third sleeve 131, the operator can move the third movable rod 132 to slide it within the third sleeve 131 according to actual needs, thereby adjusting the angle and distance between the first rotating rod 3 and the support seat 2. Then, it can be locked by the third wing bolt. The same operation method applies to the second and third telescopic rod assemblies.

[0022] During the adjustment process, the operator needs to observe the angle and position of each rotating rod to ensure that the entire support frame assembly gradually becomes vertical. After adjusting to the appropriate position, tighten the corresponding wing bolts again to fix each telescopic rod assembly. At this time, the support frame assembly is stably in a vertical support state, providing stable support for the pipeline and leaving enough passage space for pedestrians on both sides.

[0023] When encountering a narrow road requiring passage through the middle, the support frame assembly needs to be adjusted to an arched support configuration. The operator adjusts it as described above: first, adjust the first telescopic rod assembly to open the first rotating rod 3 outwards at a certain angle; then adjust the second telescopic rod assembly to make the second rotating rod 4 vertical; simultaneously, adjust the third telescopic rod assembly to make the height of the entire support frame assembly adjustable. During adjustment, the position and angle of each component must be continuously observed to gradually form an arched structure. Once the preset state is achieved, tighten the multiple wing bolts again to secure each telescopic rod assembly, ensuring the stability of the arched support configuration.

[0024] Example 2

[0025] like Figure 1 and Figure 3 As shown in the figure, the wear-resistant pipe support device for mining proposed in this embodiment, compared with the first embodiment, also includes an anti-settlement device. The anti-settlement device includes a pressure testing mechanism and an electric telescopic rod 5. The electric telescopic rod 5 is installed on the support base 2 and its output shaft is connected to the pressure testing mechanism. The clamp 1 is installed on the pressure testing mechanism. It should be added that the pressure testing device includes a clamp base 9, a mounting base 10 and a pressure sensor 11. The clamp base 9 and the mounting base 10 are respectively connected to the clamp 1 and the output shaft of the electric telescopic rod 5. The pressure sensor 11 is installed between the mounting base 10 and the clamp base 9. Guide rods 12 are connected to both ends of the clamp base 9. The guide rods 12 movably pass through the mounting base 10 and their bottom ends are connected to limit blocks.

[0026] In this embodiment, during normal pipeline operation, the pressure sensor 11 continuously monitors the supporting force of the clamp 1 on the pipeline. Since the weight and operating status of the pipeline are relatively stable, under normal circumstances, the pressure value detected by the pressure sensor 11 remains within a relatively stable range. This stable pressure value reflects the normal supporting force of the clamp 1 on the pipeline. However, when the support frame assembly experiences settlement due to various reasons, such as ground subsidence, the supporting force of the clamp 1 on the pipeline changes. Specifically, the pressure value detected by the pressure sensor 11 decreases. At this time, the pressure sensor 11 feeds back the detected signal to the microcontroller. The microcontroller analyzes the signal, and when the pressure... When the value is less than the normal range, it can be determined that the support frame assembly has settled. At this time, the microcontroller will issue a command to control the electric telescopic rod 5 to start working. The output shaft of the electric telescopic rod 5 will slowly move upward. As the output shaft rises, the mounting base 10 and the clamp base 9 will also move upward. Since the clamp 1 is installed on the clamp base 9, the clamp 1 will also move upward, gradually increasing the supporting force on the pipeline. During this process, the pressure sensor 11 will continuously detect the pressure value. When the pressure value detected by the pressure sensor 11 returns to the normal range, that is, the clamp 1 has formed a certain supporting force on the pipeline, the microcontroller will control the electric telescopic rod 5 to stop working.

[0027] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
