Description

Technical Field

[0001] This utility model relates to the field of mining technology, specifically to a mining void filling pipe adjustment device. Background Technology

[0002] The upward layered backfilling mining method is a mining method that divides the stope or block into horizontal or inclined layers in the vertical height, and mines them layer by layer from bottom to top. After each layer is mined, backfilling is carried out. This backfill is not only used to control ground pressure and manage the goaf, but more importantly, it serves as an operating platform for subsequent backfilling layers, directly bearing the load of mining and ore transportation equipment.

[0003] Currently, the common practice is to use fixed filling pipes to transport filling slurry (usually a mixture of tailings, cementing materials, and water) directly into the goaf for filling operations. However, since the slurry inlet position is fixed and the goaf space is usually large, the slurry mainly relies on its own fluidity to spread outwards after being discharged from the pipe, which often takes a long time and is difficult to achieve uniform distribution. As a result, the slurry concentration near the filling pipe inlet may be too high, while areas far from the pipe inlet are prone to insufficient filling or even voids, which seriously affects the overall strength of the final filling body. Since all mining operations except for the first layer are carried out on the filling body formed in the early stage, insufficient strength will directly endanger the safe operation of heavy mining and ore transportation equipment operating on it, and may even lead to equipment overturning or personnel casualties, posing a safety hazard.

[0004] Therefore, it is necessary to study a regulating device for filling pipes in mining voids. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a mining goaf filling pipe adjustment device, which effectively solves the problems of uneven filling of the goaf, segregation inside, and difficulty in ensuring filling strength due to the fixed position of the filling pipe, thus affecting the safety and efficiency of the operation.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a mining void filling pipe adjustment device, comprising a hanger, a guide rail, and an adjustment component. The guide rail is slidably mounted on the hanger arranged at intervals. A traveling wheel is provided inside the guide rail, and a connecting rod is rotatably mounted on the axle of the traveling wheel. The connecting rod extends vertically downwards to the outside of the guide rail. The adjustment component is located below the guide rail, and the traveling wheel is used to drive the adjustment component to move back and forth along the guide rail. The adjustment component includes a base, a fixed seat, and a drive seat. The connecting rod is fixedly connected to the top of the base, and the fixed seat is fixedly mounted on the base at intervals. An arc-shaped guide groove is opened inside the fixed seat, and the drive seat is mounted in the guide grooves on both sides. A connecting sleeve is fixed to the bottom surface of the drive seat, and a drive component is connected to the top of the drive seat. Under the action of the drive component, the drive seat can swing up and down along the extension path of the guide groove.

[0007] Furthermore, the connecting sleeve is threaded with an adjusting screw, one end of which extends into the connecting sleeve and is rotatably connected to an arc-shaped top sleeve. Tightening the adjusting screw can fix and clamp filling tubes of different inner diameters into the connecting sleeve.

[0008] Furthermore, the bottom of the guide rail is provided with a clearance groove, and the connecting rod passes vertically downward through the clearance groove to a position below the guide rail.

[0009] Furthermore, a transverse slot is provided on one side wall of the guide rail, and the shaft of the traveling wheel passes through the transverse slot to the outside of the guide rail and is connected to the traveling motor. The traveling motor is fixed to the base by a support.

[0010] Furthermore, a connecting frame is fixed below the hanger. After the filling tube is fixedly installed in the connecting sleeve, the filling tube body is suspended on the connecting frame.

[0011] Furthermore, the drive assembly includes a ring gear segment, a gear, and a swing motor. The ring gear segment is adapted and fixed to the top of the drive seat, the swing motor is fixed to the base, and the output shaft of the swing motor is fixedly fitted with a gear. The gear meshes with the ring gear segment to control the up-and-down swing of the drive seat.

[0012] The beneficial effects of the above technical solution are as follows: The mining goaf filling pipe adjustment device provided by this utility model can effectively improve the uniformity of slurry distribution in the goaf by flexibly adjusting the angle of the pipe discharge port and accurately controlling the distance and landing point of the slurry discharge. This significantly improves the segregation problem caused by concentrated single-point discharge and ultimately ensures the formation of a filling body with qualified strength and stable performance, providing a reliable guarantee for subsequent safe and efficient mining operations.

[0013] The adjusting screw and arc-shaped top sleeve design at the bottom of the connecting sleeve in this utility model allow for the fixing of filling pipes with different inner diameters by tightening the screw, facilitating replacement or adaptation to different pipe specifications. Furthermore, the connecting bracket located below the hanger effectively organizes and supports the filling pipe body when it is adjusted and moved, preventing the pipes from scattering and accumulating in the goaf. This ensures smooth filling operations and avoids the impact of messy pipes on filling efficiency and equipment safety, thus improving the reliability of the device in the complex environment of a mine.

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0021] Example 1: This example aims to provide a mining void filling pipe adjustment device, mainly used to adjust the position and angle of the filling pipe discharge port in the mine shaft, thereby improving the uniformity and strength of filling the mining void. Figure 1-4 As shown, the mining void filling pipe adjustment device provided in this embodiment includes a hanger 1, a guide rail and an adjustment component 3. The hanger 1 is fixed at intervals on the rock wall above the mining void. The guide rail is slidably mounted on the hanger 1. Specifically, the hanger 1 is provided with a locking block and the guide rail is provided with a matching slot. The locking block is fitted into the slot, driving the guide rail to be hoisted on the hanger 1 and to slide along the layout direction of the hanger 1.

[0022] like Figure 2As shown, a traveling wheel 5 is provided inside the guide rail. A clearance groove is opened at the bottom of the guide rail. A connecting rod 8 is rotatably mounted on the rotating shaft 7 of the traveling wheel 5. The connecting rod 8 passes vertically downward through the clearance groove to the bottom of the guide rail. Furthermore, to ensure that the traveling wheel 5 travels in a straight line within the guide rail, this embodiment provides a protrusion along its extension direction within the traveling rail, so that the groove inside the traveling wheel 5 matches the protrusion to guide the movement of the traveling wheel 5. A transverse slot is opened on one side wall of the guide rail 2 along its extension direction. The rotating shaft 7 of the traveling wheel 5 passes through the transverse slot to the outside of the guide rail 2 and is connected to the traveling motor 6. The traveling motor 6 is fixed to the base 31 of the adjusting assembly 3 by a support.

[0023] The adjustment assembly 3 is located below the guide rail. The adjustment assembly 3 includes a base 31, a fixed base 32, and a drive base 33. A connecting rod 8 is fixed to the top of the base 31, and the top of the connecting rod 8 is fitted onto a rotating shaft 7. The adjusting assembly 3 moves back and forth along the guide rail via the traveling wheels 5. Figure 3 and 4 As shown, the fixed seat 32 is fixedly fixed on the base 31 at intervals. The fixed seat 32 has an arc-shaped guide groove. The drive seat 33 is located between the two fixed seats 32. Its left and right sides are slidably fitted into the guide groove. The top of the drive seat 33 is connected to the drive assembly. Under the action of the drive assembly, the drive seat 33 can swing back and forth along the extension path of the guide groove.

[0024] like Figure 4 As shown, the drive assembly includes a ring gear segment 38, a gear 37, and a swing motor 36. The ring gear segment 38 is adapted and fixed on the top of the drive seat 33, the swing motor 36 is fixed on the base 31, and the output shaft of the swing motor 36 is fixedly fitted with the gear 37. The gear 37 meshes with the ring gear segment 38 and is used to control the drive seat 33 to swing up and down along the extension path of the guide groove 35.

[0025] A connecting sleeve 34 is fixed to the bottom of the drive base 33. In this embodiment, an adjusting screw 9 is threadedly connected to the bottom of the connecting sleeve 34. The top of the adjusting screw 9 extends into the connecting sleeve 34, and its end is rotatably connected to an arc-shaped top sleeve 10. Tightening the adjusting screw 9 drives it to move back and forth in the connecting sleeve 34, which is used to fix and clamp filling pipes of different inner diameters in the connecting sleeve 34. After the end of the filling pipe is fixed and clamped in the connecting sleeve 34, the walking motor 6 drives the walking wheel 5 to move back and forth along the guide rail. The position of the filling pipe in the goaf can be adjusted synchronously, thereby controlling the position of the slurry discharge port in the filling pipe. In conjunction with the adjusting component 3, the swing angle of the filling pipe can be adjusted to control the distance and landing point of the slurry discharge.

[0026] In addition, to prevent the filling pipe body from scattering in the goaf during the movement of the filling pipe driven by the connecting sleeve 34, which would affect the filling effect of the goaf and the layout of the pipeline, a connecting frame 4 is also fixed below the hanger 1 in this embodiment. After the filling pipe is fixedly clamped in the connecting sleeve, the filling pipe body can be hoisted on the connecting frame for pipeline arrangement. When the slurry in the goaf is filled to the position below the adjusting screw, the filling operation can be stopped, and then the capping can be carried out according to the construction operation to prevent the adjusting screw from being blocked by the solidified slurry.

[0027] The mining void filling pipe adjustment device provided by this utility model, in practical application, firstly fixes the hanger to the rock wall of the mining void, and the guide rail is hoisted on the hanger through the cooperation of the locking block and the locking slot (it should be noted that the length of the guide rail can be adjusted adaptively according to the actual situation in the mining void, and the layout of the hanger should be adapted to the length of the guide rail, which can be done before the capping). Then, the adjustment component is installed on the guide rail, and according to the inner diameter of the filling pipe, the adjusting screw is turned to fix the filling pipe in the connecting sleeve, and at the same time, the filling pipe body is hoisted on the connecting frame to tidy up the pipe and prevent the pipe body from falling and affecting the filling effect and pipe layout. Then, the walking motor is started to drive the filling pipe forward along the guide rail, which can be used for unloading the filling slurry. Beforehand, the position of the filling pipe within the goaf is adjusted in advance using a walking motor to control the position of the slurry discharge outlet within the filling pipe; adaptive adjustments are made during the slurry discharge process; furthermore, when the filling pipe moves to the innermost end of the guide rail, the swing motor can be driven to swing the drive seat back and forth along the arc-shaped guide groove within the fixed seat, thereby adjusting the swing angle of the filling pipe and controlling the distance and landing point of the slurry discharged inward, thus improving the uniformity and strength of the filling of the goaf; when the slurry in the goaf is filled to the position below the adjusting screw, the filling operation is stopped, and the cap is sealed according to the construction operation situation to prevent the adjusting screw from being blocked by the solidified slurry, and before the cap is sealed, the guide rail and adjusting components can be recycled outside the goaf for repeated use.

[0028] The mining void filling pipe adjustment device provided in this embodiment is ingeniously designed and highly adaptable. Driven by a walking motor, the walking wheels move along the guide rail below the hanger, allowing for flexible adjustment of the filling pipe's horizontal position within the mining void. Simultaneously, the swing motor in the adjustment assembly drives a gear that meshes with a ring gear section, causing the drive seat to swing up and down along the arc-shaped guide groove within the fixed seat. This changes the inclination angle of the filling pipe's outlet end. Through this dual adjustment capability of position and angle, operators can precisely control the slurry discharge point and spray distance as needed, significantly improving the uniformity of the filling slurry distribution within the mining void and contributing to the formation of a more complete and stronger filling body.

[0029] Example 2 is based on Example 1. The similarities between this example and Example 1 will not be repeated here. The differences are as follows: Figure 5 As shown, in this embodiment, the adjusting screw is threaded onto the side wall of the connecting sleeve to press the filling tube inside the connecting sleeve. When the adjusting screw is in the side position, it is still located inside the connecting frame, preventing the adjusting screw from extending outside the connecting frame and causing interference when it moves back and forth along the guide rail. This setting greatly improves the convenience of adjustment and the safety of operation. At the same time, the filling tube is clamped by horizontal force, resulting in more uniform force distribution. Furthermore, it can prevent the adjusting screw from being buried and covered by slurry due to operator error, thus improving the safety of use.

[0030] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
