Description
Technical Field
[0001] This invention belongs to the technical field of pipeline protection equipment, specifically a high-pressure oil pipeline protection device for a coal mill and its usage method. Background Technology
[0002] The coal grinding process is the process of crushing coal and continuously increasing its surface area. To increase the new surface area, the binding forces between solid molecules must be overcome, which requires energy. Coal is ground into pulverized coal in a coal mill, mainly through three methods: crushing, impact crushing, and grinding. Among these, the crushing process consumes the least energy, while the grinding process consumes the most energy. Various coal mills combine two or three of the above methods in the pulverizing process, but the dominant method depends on the type of coal mill.
[0003] However, in existing technologies, the existing coal mill pipelines are subject to frequent vibrations during coal mill operation. Since the pipelines are closely spaced, prolonged operation can easily lead to severe friction between them, causing significant wear and tear at the friction points. This can result in leakage of the transported fluid, preventing the coal mill from functioning properly and polluting the surrounding environment. Current solutions often involve wrapping protective tape or pipes around the friction points. However, the adhesive tape is difficult to replace after wear and can only be fixed in a designated location, resulting in poor maintenance. Similarly, the protective pipes cannot adhere well to their intended location, making them prone to displacement under vibration and causing compression between the pipelines. This further increases the risk of friction between other parts and the surrounding environment, leading to inadequate protection. Summary of the Invention
[0004] The purpose of this invention is to provide a coal mill high-pressure oil pipeline protection device and its usage method that can conveniently restrict the support between any parts of the pipeline body according to actual use, facilitate maintenance and replacement, prevent positional displacement, avoid excessive increase in the distance between pipeline bodies, prevent accidental friction between other parts of the pipeline body and the surrounding environment, and improve the actual protection effect.
[0005] The technical solution adopted in this invention is as follows: A high-pressure oil pipeline protection device for a coal mill, comprising: a fixing mechanism, the fixing mechanism including a base frame, the base frame having extension strips fixedly connected near both sides, each extension strip having multiple positioning holes equidistantly opened on its outer surface, mounting grooves being opened on both sides of the outer surface of the base frame, an adjusting bolt being threadedly connected to one side of the outer surface of the base frame, one end of the adjusting bolt extending into the interior of the base frame, and the other end of the adjusting bolt being rotatably connected to a positioning pressure strip; and
[0006] A limiting mechanism is provided, comprising mounting rods and limiting components. Two mounting rods are provided, with each end of the two mounting rods passing through a corresponding mounting groove. An mounting strip is sleeved between the outer surfaces of the two mounting rods, with each end of the mounting strip embedded in a corresponding mounting groove. A connecting frame is slidably sleeved on the outer surface of the mounting strip, and the limiting component is disposed on the connecting frame.
[0007] The positioning strip has positioning blocks fixedly connected to both sides at the center of one outer surface, and one end of each positioning block extends into the corresponding positioning hole.
[0008] The connecting frame has connecting holes on both sides at the center of the inner wall of one side. A connecting bolt is slidably inserted into each connecting hole, and the two connecting bolts are threaded to the outer surface of one side of the mounting strip.
[0009] The connecting frame has slots on both its top and bottom surfaces.
[0010] The limiting component includes a limiting frame, which is slidably embedded between two slots and the connecting frame. Two sets of limiting plates are fixedly connected between the bottom and top surfaces of the limiting frame. Each set of limiting plates has two plates. A set of reset rods slides through the outer surfaces of the two limiting plates in each set. Each set of reset rods has two reset rods. A clamping block is sleeved between the outer surfaces of the two reset rods in each set.
[0011] Each of the reset rods has a reset spring slidably sleeved on its outer surface, and each of the reset springs has a pressure ring sleeved on its outer surface.
[0012] The limiting frame has a card plate fixedly connected to one side of its outer surface, and the card plate has a slot on one side of its outer surface.
[0013] The bayonet has a bottom rod slidably inserted inside, a top block is fixedly connected to one end of the bottom rod, an adjusting ring is threadedly connected to the outer surface of the bottom rod, a push tube is slidably sleeved on the outer surface of the bottom rod, one end of the push tube is rotatably connected to one end of the adjusting ring, a top ring is slidably sleeved on the outer surface of the bottom rod, one end of the top ring is rotatably connected to the other end of the push tube.
[0014] The bottom rod has a steering ring threadedly connected to its outer surface, and a rotating groove is provided at the other end of the bottom rod. A steering connecting shaft is slidably inserted into the rotating groove, and one end of the steering connecting shaft slides through the inner wall of one side of the steering ring.
[0015] A method for using a high-pressure oil pipeline protection device for a coal mill includes the following steps:
[0016] S1. Protection and Adjustment: Based on the actual friction contact position of the pipeline body, the equipment can be fitted onto the designated usage position on the surface of the pipeline body through the base frame and extension strip. By rotating the adjusting bolt, the adjusting bolt can squeeze the adjusting positioning strip, which in turn can adjust the gap between the extension strip and the base frame through the positioning block and positioning hole, so that the equipment can be stably set in the designated usage position. Under the action of the steering connecting shaft, the base rods on different pipeline bodies can be connected. At the same time, under the position restriction of the steering ring and the base rod, the steering connecting shaft can automatically change its own usage angle according to the actual usage situation, so that the equipment can adjust its usage state in response to the vibration of the pipeline body.
[0017] S2. Adaptive Adjustment: By rotating the adjustment ring, the rotating adjustment ring can work with the push tube to squeeze the top ring to gradually fit the corresponding top block, so that the top ring can support and limit the position of the clamping block, and the top block can smoothly disengage from the corresponding two clamping blocks, thus facilitating the connection and adjustment between devices in different positions.
[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:
[0019] In this invention, during use, based on the actual friction contact position of the pipeline body, the device can be fitted onto the designated usage position on the pipeline body surface via the base frame and extension strip. Then, by rotating the adjusting bolt, the adjusting bolt can press the adjusting positioning strip, allowing the positioning strip to effectively adjust the gap between the extension strip and the base frame through the positioning block and positioning hole. This ensures the device is stably installed in the designated usage position, thus meeting the needs of different specifications of pipeline bodies and improving the versatility of the device in actual use. Furthermore, under the action of the steering connecting shaft, effective connection of the base rods on different pipeline bodies can be achieved. Simultaneously, under the positional constraints of the steering ring and base rods, the steering connecting shaft can automatically adjust itself according to actual usage conditions. By changing the angle of use, the equipment can adjust its operating state according to the vibration of the pipeline body, effectively preventing mutual friction between pipeline bodies and preventing excessive compression support between adjacent pipeline bodies, which could affect the normal use of other parts of the pipeline body. At the same time, by rotating the adjustment ring, the rotating adjustment ring can work with the push-pipe pressing top ring to gradually fit against the corresponding top block, so that the top ring can effectively support and limit the position of the clamping block, allowing the top block to smoothly disengage from the corresponding two clamping blocks. This facilitates the connection and adjustment between equipment in different positions, enabling the equipment to meet the needs of different conditions, and also facilitates convenient maintenance, installation and replacement of the equipment, allowing the equipment to efficiently realize its intended functions.

[0031] The following provides a detailed description of the usage method of a high-pressure oil pipeline protection device for a coal mill provided in an embodiment of the present invention. The usage method includes the following steps:
[0032] Step 1, Protection and Adjustment: Based on the actual friction contact position of the pipeline body 3, the equipment can be fitted onto the designated usage position on the surface of the pipeline body 3 using the base frame 101 and extension strip 102. Then, by rotating the adjusting bolt 103, the adjusting bolt 103 can press the adjusting positioning strip 104. The positioning strip 104, through the positioning block 105 and positioning hole, can effectively adjust the gap between the extension strip 102 and the base frame 101, ensuring the equipment is stably installed in the designated usage position. This allows the equipment to meet the needs of pipeline bodies 3 of different specifications, improving the equipment's performance. The wide applicability of the equipment allows for effective connection of the bottom rods 212 on different pipeline bodies 3 under the action of the steering connection shaft 218. At the same time, under the positional constraints of the steering ring 217 and the bottom rod 212, the steering connection shaft 218 can automatically change its own operating angle according to the actual usage conditions. This allows the equipment to adjust its operating state in response to the vibration of the pipeline body 3, effectively preventing mutual friction between pipeline bodies 3 and preventing excessive compression support between adjacent pipeline bodies 3, which would affect the normal use of other parts of the pipeline body 3.
[0033] Step 2, Adaptation and Adjustment: By rotating the adjustment ring 214, the rotating adjustment ring 214 can cooperate with the push tube 215 to squeeze the top ring 216 to gradually fit against the corresponding top block 213. This allows the top ring 216 to effectively support and restrict the position of the clamping block 210, enabling the top block 213 to smoothly disengage from the corresponding two clamping blocks 210. This facilitates the connection and adjustment between devices in different positions, allowing the equipment to meet the needs of different situations. It also enables convenient maintenance, installation, and replacement of the equipment, allowing the equipment to efficiently perform its intended functions.
