Description

Technical Field

[0001] The utility model relates to the technical field of pipeline fixing, in particular to a pipeline fixing device used underground. Background Art

[0002] In the mining industry, a large number of pipes are needed in mines to transport gas, liquid or fluid with solid particles, etc. Among them, large pipes are installed on the concrete wall of the shaft through fixing devices. The setting of the concrete wall improves the stability of the connection between the shaft and the fixing device, so that the large pipes can be more stably connected to the inner wall of the shaft. However, when large pipes transport liquid for a long time, the pipes will become heavier. At the same time, the vibration generated by the transportation of liquid in the pipe is easy to drive the fixing device to vibrate through the pipe, and then the fixing device is easy to shake on the concrete wall, causing the concrete wall to crack. There is a risk of causing the pipe and the fixing device to fall off from the inner wall of the shaft.

[0003] For this purpose, we propose an underground pipe fixing device with good supporting effect and stable structure. Utility Model Content

[0004] The utility model provides a pipeline fixing device for underground wells to solve the background technology

[0005] The questions raised in .

[0006] In order to solve the above problems, the utility model provides a pipe fixing device for underground use, including a mounting frame and a clamping mechanism. The mounting frame is installed on the wall of the mine through mounting holes opened at the upper and lower ends and matched with bolts. A first support plate is fixedly arranged at the middle end of the outer side of the mounting frame, and a second support plate is fixedly arranged at the lower end above the mounting hole. There are two clamping mechanisms, one of which is arranged above the first support plate and the other above the second support plate. The clamping mechanism is composed of a fixing plate, a clamping hoop and a clamping plate. A matching clamping hoop is opened in the outer side surface of the fixing plate and is coaxial with the clamping hoop. The semicircular arc groove is semicircular, and the clamp is semicircular and is installed on the outer side of the fixed plate by matching bolts at both ends. The clamping plate is two symmetrical semicircular arcs, and a plurality of guide rods are equidistantly arranged on the outer side of the clamping plate. One of the clamping plates is slidably connected to the fixed plate through the guide rod, and the other clamping plate is slidably connected to the clamp through the guide rod. A spring is sleeved in the guide rod, and the spring slidably connected to the guide rod in the fixed plate is located between the fixed plate and the clamping plate, and the spring slidably connected to the guide rod in the clamp is located between the clamp and the clamping plate.

[0007] Preferably: the bottom end of the fixed plate in the clamping mechanism above the first support plate is fixedly connected to the first support plate, and the side is fixedly connected to the mounting frame, the top and bottom ends of the fixed plate in the clamping mechanism above the second support plate are respectively fixedly connected to the lower side of the first support plate and the upper side of the second support plate, and the side is fixedly connected to the mounting frame.

[0008] Preferably: an adjustment support foot supported on the ground is provided on the lower side of the second support plate, the adjustment support foot is composed of a threaded base and an adjustment foot, and the threaded base is fixedly installed under the second support plate, and the adjustment foot is threadedly connected to the threaded base.

[0009] The beneficial effects of adopting the above technical solution are:

[0010] By means of the mounting frame cooperating with the first support plate, the second support plate and the clamping mechanism arranged above the first support plate and the second support plate, two pipes can be clamped and installed at the same time, thereby improving work efficiency.

[0011] The coordination of the arc groove, clamp, clamping plate, spring and guide rod in the fixing plate makes it easy to clamp the pipe. At the same time, the clamped pipe is shock-absorbed by the clamping plate, spring and guide rod, thereby avoiding the risk of the mounting frame falling off from the well wall concrete due to vibration.

[0012] By adjusting the setting of the support feet, the installed pipe can be supported by the ground, further improving the stability after installation, avoiding the risk of the mounting frame falling off the concrete well wall due to excessive weight of the pipe and vibration during transportation, and improving work stability.

[0020] like Figure 1-3 In this embodiment, a pipe fixing device for underground use includes a mounting frame 1 and a clamping mechanism 2. The mounting frame 1 is mounted on the shaft wall 3 of the mine through mounting holes 11 opened at the upper and lower ends and bolts. A first support plate 4 is fixedly arranged at the middle end of the outer side of the mounting frame 1, and a second support plate 5 is fixedly arranged at the lower end above the mounting hole 11. There are two clamping mechanisms 2, one of which is respectively arranged above the first support plate 4 and the second support plate 5. The clamping mechanism 2 is composed of a fixing plate 21, a clamping hoop 22, and a clamping plate 23. A matching clamping hoop 22 is opened in the outer side surface of the fixing plate 21, and a semicircular arc groove coaxial with the clamping hoop 22 is provided. The clamping hoop 22 It is semicircular and is installed on the outer side of the fixed plate 21 by matching bolts at both ends. The clamping plates 23 are two symmetrical semicircular shapes, and a number of guide rods 24 are equidistantly arranged on the outer side of the clamping plates 23. One of the two clamping plates 23 is slidably connected to the fixed plate 21 through the guide rod 23, and the other clamping plate 23 is slidably connected to the clamp 22 through the guide rod 24. A spring 25 is sleeved in the guide rod 24, and the spring 25 slidably connected to the guide rod 24 in the fixed plate 21 is located between the fixed plate 21 and the clamping plate 23, and the spring 25 slidably connected to the guide rod 24 in the clamp 22 is located between the clamp 22 and the clamping plate 23.

[0021] Through the above technical scheme: when in use, the equipment is installed on the well wall 3 through the mounting holes 11 at the upper and lower ends of the mounting frame 1 with the help of bolts, and then the pipe to be fixed is first placed in the clamping mechanism 2 above the second support plate 5 according to the situation, and the clamp 22 is installed on the fixing plate 21 by bolts, so as to facilitate the fixing of the pipe in the clamping mechanism 2, and at the same time the clamping plate 23 is in contact with the outer surface of the pipe. When the pipe vibrates, the clamping plate 23 moves on the fixing plate 21 or the clamp 22 through the cooperation of the guide rod 24 and the spring 25, so as to complete the shock absorption, avoid the shaking of the mounting frame 1 caused by vibration, avoid the cracking of the concrete in the well wall 3 due to shaking, and cause the pipe to fall off, thereby improving the stability after fixation, and by setting the clamping mechanism 2 above the first support plate 4, it is convenient to fix more than one pipe, thereby improving the convenience of work.

[0022] Preferably: the bottom end of the fixing plate 21 in the clamping mechanism 2 arranged above the first support plate 4 is fixedly connected to the first support plate 4, and the side is fixedly connected to the mounting frame 1, and the top and bottom ends of the fixing plate 21 in the clamping mechanism 2 arranged above the second support plate 5 are respectively fixedly connected to the lower side surface of the first support plate 4 and the upper side surface of the second support plate 5, and the side surface is fixedly connected to the mounting frame 1.

[0023] Through the above technical scheme, the setting of the fixed plate 21 improves the support of the clamping mechanism 2 in the mounting frame 1, thereby facilitating the stable clamping of the pipeline on the mounting frame 1. The top and bottom ends of the fixed plate 21 in the clamping mechanism 2 above the second support plate 5 are respectively fixedly connected to the first support plate 4, the second support plate 5, and the mounting frame 1, thereby providing effective supporting force to the first support plate 4 while ensuring its own structural stability, thereby ensuring the stability of the clamping mechanism 2 on the first support plate 4 after clamping the pipeline.

[0024] Preferably: the lower side of the second support plate 5 is provided with an adjustment support foot 6 supported on the ground, the adjustment support foot 6 is composed of a threaded base 61 and an adjustment foot 62, and the threaded base 61 is fixedly installed under the second support plate, and the adjustment foot 62 is threadedly connected to the threaded base 61.

[0025] Through the above technical solution, the setting of the adjustable support foot 6 can provide a supporting force to the mounting frame 1 through the ground, thereby reducing the influence of the pipe weight on the mounting frame 1, avoiding the problem of cracking of the concrete on the well wall 3 and falling off of the pipe due to excessive weight of the pipe. The threaded connection between the adjusting foot 62 and the threaded base 61 facilitates the adjustment of the distance from the ground, thereby improving the fault tolerance during installation.
