Abstract
Description
Technical Field
[0001] This utility model relates to an auxiliary equipment for underground mining, specifically a lifting and adjusting device for filling overhead pipelines. Background Technology
[0002] As a critical transport medium for fluids such as filling slurry, overhead pipelines often need to cope with lifting and lowering requirements in scenarios involving geological subsidence, dynamic obstacle avoidance, and maintenance. Overhead pipelines are exposed to complex environments for extended periods, facing threats from geological subsidence, temperature-induced deformation, and external disturbances (such as wind loads and vibrations). Traditional fixed supports struggle to dynamically adapt to pipeline deformation, easily leading to stress concentration, leaks at connections, and even breakage accidents. To address this, CN202021721660.6 discloses an adjustable pipe support, comprising a base, a movable plate, a screw, a clamping mechanism, two guide rods, and two nuts. The bottom of the guide rod is fixed to the base, and a guide sleeve is fitted onto the guide rod. The movable plate is positioned between the two guide sleeves and connects them. The movable plate has a strip-shaped hole and a rod hole. A scale is provided on the base, with its upper end passing through the strip-shaped hole. The bottom of the screw is fixed to the base, and its upper end passes through the rod hole. Two nuts are fitted onto the screw and are located on the upper and lower sides of the movable plate, respectively. The clamping mechanism includes a fixed base, a hinge assembly, two semi-circular clamps, and three bolts. Springs are connected to the ends of the bolts, and arc-shaped plates are connected to the springs. This utility model is ingeniously designed and easy to use.
[0003] However, the above-mentioned adjustable pipe supports have significant drawbacks when directly applied to underground mining environments: their precision screw-nut adjustment mechanism is prone to jamming or corrosion failure due to high dust, humidity, and corrosive environments, resulting in paralysis of the height adjustment function; the spring clamping device in the clamping structure is prone to fatigue and loosening under continuous vibration, posing a risk of pipe detachment; the lightweight base and roller design lacks stability in sloping or uneven roadways, which may lead to overturning accidents; and the overall structure is difficult to meet the stringent requirements of mining environments for equipment reliability, safety, and maintenance-free operation. Utility Model Content
[0004] In view of this, the present invention discloses an overhead pipeline lifting and adjusting device suitable for underground filling mining areas, so as to achieve stable and reliable adjustment of pipeline height.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A lifting and adjusting device for filling overhead pipelines includes a base, on which a support sleeve is fixed. A telescopic rod is inserted into the support sleeve, and a nut for controlling the up-and-down movement of the telescopic rod is fixed to the top of the support sleeve via a bearing. The outer circumference of the telescopic rod is provided with threads that match the inner ring of the nut. A pipeline support is fixed to the top of the telescopic rod. The pipeline support includes an upper support and a lower support that are hinged to each other at one end, and the other ends of the upper support and the lower support are fixedly connected by bolts. The inner sides of the upper support and the lower support are provided with arc-shaped grooves that match the outer circumference of the pipeline. Shock-absorbing rubber for clamping the pipeline is fixed in the arc-shaped grooves, and the inner surface of the shock-absorbing rubber is also provided with multiple limiting protrusions.
[0007] Compared with the prior art, the present invention has the following beneficial effects:
[0008] 1. The pipe support can be adjusted up and down by rotating the nut to control the telescopic rod, so as to achieve the purpose of stable lifting of the overhead pipe. During the entire filling and connection process, the operator only needs to rotate the nut, without the need for manual handling and lifting of the pipe, which significantly reduces the intensity of manual labor, reduces mechanical damage caused by handling the pipe, and improves the inherent safety level on site.
[0009] 2. By setting shock-absorbing rubber and setting limiting protrusions on the inner side of the shock-absorbing rubber, the friction between the rubber and the pipe is increased, while the amount of swaying of the pipe in the length direction is reduced, thus protecting the pipe while ensuring clamping force.

[0011] In the diagram: 1-base, 2-support sleeve, 3-telescopic rod, 4-pipe support, 41-upper support, 42-lower support, 5-shock-absorbing rubber, 6-nut, 7-limiting protrusion, 8-fixing screw hole. Detailed Implementation
[0012] The present invention will be further explained below with reference to the accompanying drawings.
[0013] Pipeline supports are an important component of underground filling systems in mines. In the past, when underground filling pipes were connected or reconnected after the fixed supports were damaged or missing, the entire process of lifting the pipes was done manually. It took four people to lift one filling pipe, which was time-consuming, labor-intensive, and consumed a lot of manpower. Because the effort of each person was uneven, there was a safety hazard of the pipes tipping over and injuring the workers. At the same time, since underground filling pipes are laid along the ash slope of the access road, in the past, when connecting the pipes, it was necessary to make a hole in the ash slope to serve as a support point for the lifting rod. This method had the safety hazard of the lifting rod slipping off due to the unstable support point and injuring the workers.
[0014] Therefore, this utility model discloses a lifting and adjusting device for filling overhead pipelines, such as... Figure 1 As shown, the system includes a base 1 with fixing screw holes 8 at its four corners. A support sleeve 2 is fixed in the middle of the base 1, and a telescopic rod 3 is inserted into the support sleeve 2. A nut 6 for controlling the up-and-down movement of the telescopic rod 3 is fixed to the top of the support sleeve 2 via a thrust bearing. The outer circumference of the telescopic rod 3 is provided with threads that match the inner ring of the nut 6. A pipe support 4 is fixed to the top of the telescopic rod 3. The pipe support 4 includes an upper support 41 and a lower support 42 that are hinged to each other at one end. The other ends of the upper support 41 and the lower support 42 are fixedly connected by bolts. The inner sides of the upper support 41 and the lower support 42 are provided with arc-shaped grooves that match the outer circumference of the pipe. A shock-absorbing rubber 5 for clamping the pipe is fixed in the arc-shaped groove. The inner surface of the shock-absorbing rubber 5 is also provided with multiple limiting protrusions 7.
[0015] During installation, first, fix the base 1 to the rock surface using anchor bolts installed in the fixing screw holes 8. Then, open the pipe support 4, place the pipe between the upper support 41 and the lower support 42, and ensure that the shock-absorbing rubber 5 is tightly fitted to the outer circumference of the pipe before tightening the fixing bolts at the other end of the upper support 41 and the lower support 42. Next, according to the pre-connected pipe height, turn the nut 6 to pull the telescopic rod 3 out from the support sleeve 2 until it is at the same height as the pipe to be connected, then stop turning the nut 6. The nut 6 will self-lock under the pressure of the filling pipe. Finally, the filling pipe connection is completed.
[0016] This utility model can be directly fixed to the rock surface of the tunnel along the direction of the filling overhead pipeline, and can be adjusted as needed, which greatly saves manpower and material resources. It has a simple structure, is easy to use, and has good practicality.
