[0027] See also Figure 1-Figure 8 The utility model provides a pipeline protection device for mining engineering, which has a connecting base 1 with a hollow structure inside. Four groups of symmetrically distributed moving blocks 2 are slidably arranged on the top surface of the connecting base 1. A driving component for driving the moving block 2 to move is arranged inside the connecting base 1. A buffer component is arranged on one side of the moving block 2. The moving block 2 is driven to move by the driving component, and the force exerted on the pipe joint is dispersed by the buffer component. The driving component includes a bidirectional screw 6 that passes through the interior of the connecting base 1 and is screwed to the bottom of the moving block 2, and a handle 5 is arranged at the end of the bidirectional screw 6. The buffer component includes a plurality of groups of pipe sleeves 7 with a hollow structure inside that are fixedly arranged on the side surface of the moving block 2, a first spring 10 fixedly arranged on the inner bottom surface of the pipe sleeve 7, and an abutment block 8 fixedly arranged on the top end of the first spring 10.

[0028] See also Figure 1-Figure 7 Preferably, a limiting assembly is provided on the top of the moving block 2 of the utility model, and the limiting assembly includes a box body 11 fixed to the top surface of the moving block 2 and having a hollow structure inside, a limiting rod 12 passing through the box body 11 and the moving block 2, and a second spring 13 sleeved on the limiting rod 12 and located inside the box body 11. The hollow structure of the box body 11 facilitates the movement of the limiting rod 12 and the second spring 13.

[0029] See also Figure 5 and Figure 6 In addition, the top end of the second spring 13 of the utility model is fixedly connected to the inside of the box body 11, and the bottom end of the second spring 13 is fixedly provided with a limit block 14, and the limit block 14 is fixedly sleeved on the limit rod 12. When the limit rod 12 moves upward, it will drive the limit block 14 to move upward. The upward movement of the limit block 14 drives the second spring 13 to deform, so that when no force is applied to the limit rod 12, the second spring 13 can drive the limit rod 12 to reset.

[0030] See also Figure 6Furthermore, when the second spring 13 of the utility model is not subjected to external force, the limit block 14 abuts against the inner bottom surface of the box body 11, so that the second spring 13 drives the limit block 14 to reset.

[0031] See also Figure 1 and Figure 7 Moreover, a buffer pad 9 is provided at the end of the abutment block 8 of the utility model away from the first spring 10. The radius of the buffer pad 9 is greater than the radius of the pipe sleeve 7. The buffer pad 9 can avoid impact and damage to the clamp-type pipe joint. At the same time, the radius of the buffer pad 9 is large, and the buffer pad 9 will not enter the interior of the pipe sleeve 7.

[0032] See also Figure 1 and Figure 2 At the same time, a groove 15 is provided at the connection point between the top of the connecting base 1 and the moving block 2 of the utility model, and the groove 15 facilitates the movement of the moving block 2.

[0033] See also Figure 1-Figure 2 , Figure 4 and Figure 7-Figure 8 Better yet, the utility model provides a movable block 3 and a fixed block 4 between the two groups of movable blocks 2 in a direction perpendicular to the screw, and buffer components are provided on the sides of the movable block 3 and the fixed block 4. The setting of the movable block 3 facilitates the installation of the device on the outside of the pipeline and provides protection for the pipeline and the pipe joint.

[0034] See also Figure 1-Figure 2 , Figure 4 and Figure 7-Figure 8 Finally, a slide groove 16 is provided at the connection between the moving block 2 and the movable block 3 of the utility model, and a through hole 17 matching the limiting rod 12 is provided on the movable block 3. The slide groove 16 is convenient for placing the movable block 3, and the through hole 17 is convenient for connecting the movable block 3 with the limiting rod 12.

[0035] The working principle of this utility model:

[0036] First, the device is used after the pipeline has been connected, so the staff needs to pull up the limit rod 12 first, and then take the movable block 3 out of the slide groove 16 to facilitate the connection of the device with the pipeline, and then connect the connecting base 1 to the external wall through bolts and other fixings, insert the movable block 3 into the slide groove 16 again, and then loosen the limit rod 12, so that the limit rod 12 is reset under the action of the second spring 13, and the limit rod 12 can pass through the through hole 17 on the movable block 3, so as to limit the movable block 3 and prevent the movable block 3 from falling after being stressed. The four groups of moving blocks 2 are symmetrically arranged on both sides of the clamp-type pipe joint. At this time, the bidirectional screw 6 is rotated by the handle 5, and the bidirectional screw 6 drives the moving blocks 2 to move toward each other, so that the buffer pad 9 is abutted against the side of the pipe joint. When the pipeline is affected by external vibration, the pipe joint vibrates, and a force is exerted on the buffer pad 9 at this time. The buffer pad 9 transmits the force to the abutment block 8 and the first spring 10. Under the action of the first spring 10, the force is dispersed, thereby reducing the influence of the direct vibration force on the pipe joint and reducing the loss of the pipe joint.

[0037] In summary, the utility model provides a pipeline protection device for mining engineering, comprising: a connecting base with a hollow structure inside, four groups of symmetrically distributed moving blocks are slidably provided on the top surface of the connecting base, a driving component for driving the moving block to move is provided inside the connecting base, a buffer component is provided on one side of the moving block, the moving block is moved by the driving component, and the force exerted on the pipe joint is dispersed by the buffer component; the driving component comprises a bidirectional screw that passes through the interior of the connecting base and is threadedly connected to the bottom of the moving block, and a handle is provided at the end of the bidirectional screw; the buffer component comprises a plurality of groups of pipe sleeves with a hollow structure inside that are fixed to the side surface of the moving block, a first spring fixed to the inner bottom surface of the pipe sleeve, and an abutment block fixed to the top end of the first spring. In summary, the utility model fixes the base with the outer wall through the connection, and then drives the bidirectional screw to rotate through the handle, so that the moving block moves to one side of the clamp-type pipe joint, so that the abutment block abuts against the pipe joint. When the pipe joint is affected by vibration, the force of the pipe joint will be transmitted to the abutment block, and then the abutment block disperses the vibration force through the deformation of the first spring, thereby reducing the direct vibration force on the pipe joint and reducing the loss to the pipe joint.
