Description

Technical Field

[0001] This utility model belongs to the field of tunnel filling, and particularly relates to a tunnel filling device along the goaf. Background Technology

[0002] Goaf retention is a coal mining technique whose basic principle can be summarized in two steps: "goaf retention" and "road retention." "Goaf retention" refers to setting up supports along the edge of the goaf area behind the coal face during the advance of the working face to support and maintain the stability of the roadway. "Road retention" refers to preserving the original intake roadway, reinforcing and supporting it, and using it directly as the return airway for the next working face. Filling the goaf retention roadway involves transporting the mixed filling material to the filling location via a filling pump and filling pipeline, and then filling it. During the filling process, it is necessary for personnel to manually hold the discharge pipe and insert it into the filling location to fill the material. Holding the discharge pipe for extended periods can cause hand pain and wastes manpower. Utility Model Content

[0003] The purpose of this utility model is to provide a filling device for retaining space along the goaf, so as to solve the technical problems mentioned in the background art.

[0004] To achieve the above objectives, the specific technical solution of the gob-side retaining and filling device of this utility model is as follows:

[0005] A gob-side filling device includes a support base, a lifting device mounted on the support base, a receiving plate mounted on the lifting device, and a clamping assembly rotatably mounted on the receiving plate via a pallet for fixing a discharge pipe. A reciprocating device is located on the receiving plate to drive the clamping assembly in reciprocating motion. The clamping assembly includes a first clamping plate mounted on the pallet, and second electric push rods distributed on the top surface of the first clamping plate, with the telescopic ends of each second electric push rod connected via the second clamping plate. Casters are distributed on the bottom surface of the support base.

[0006] Furthermore, the reciprocating device includes a support arm disposed on the circumferential wall of the pallet and a reciprocating mechanism disposed on the receiving plate. The support arm is arranged radially along the pallet and has a guide groove. The reciprocating mechanism includes a first motor disposed on the receiving plate, a mounting plate disposed on the first motor, and an eccentric shaft disposed at one end of the mounting plate, the eccentric shaft being inserted into the guide groove.

[0007] Furthermore, a first groove is formed on the receiving plate, and a first slide plate is slidably disposed within the first groove. A first motor is disposed on the first slide plate. A third electric push rod is disposed within the first groove and is connected to the first slide plate.

[0008] Furthermore, the support is equipped with a sliding assembly, and the lifting device is mounted on the sliding assembly. The sliding assembly includes a second sliding groove on the support, baffles at both ends of the support that block the second sliding groove, and a screw rotatably mounted on the two baffles. The screw passes through the second sliding groove, and a second sliding plate is slidably mounted within the second sliding groove. The lifting device is mounted on the second sliding plate, and the screw passes through the second sliding plate and is threadedly connected to it. A second motor is mounted on the outer wall of one of the baffles, and the second motor is connected to the screw.

[0009] Furthermore, the lifting device is a first electric push rod.

[0010] Furthermore, telescopic rods are distributed between the second sliding plate and the receiving plate.

[0011] Furthermore, the top surface of the first clamping plate has a groove, and the bottom surface of the second clamping plate has a V-shaped frame.

[0020] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a goaf-retaining and filling device.

[0021] like Figures 1 to 3 As shown, this utility model discloses a gob-side retaining filling device, including a support base 1, a lifting device mounted on the support base 1, a receiving plate 3 mounted on the lifting device, and a clamping assembly 4 rotatably mounted on the receiving plate 3 via a tray 7 for fixing the discharge pipe. It should be noted that the discharge pipe is a pipe for discharging filling material. After the clamping assembly 4 clamps and fixes the discharge pipe, the lifting device is activated. The lifting device, through the receiving plate 3, lifts the discharge pipe on the clamping assembly 4 to a suitable position, and then the filling device is activated. The material in the filling device fills the filling position through the discharge pipe. To facilitate the movement of the gob-side retaining filling device, casters 21 are distributed on the bottom surface of the support base 1, with each caster 21 located at one of the four corners of the bottom surface of the support base 1. Preferably, each caster 21 is equipped with a braking device, which facilitates the movement of the gob-side retaining filling device to a suitable position and its subsequent fixing. Preferably, a reciprocating device is provided on the receiving plate 3 to drive the clamping assembly 4 to reciprocate. The reciprocating device can drive the discharge pipe on the clamping assembly 4 to reciprocate, thereby increasing the flow range of the material in the discharge pipe and improving the uniformity of the material in the filling position.

[0022] The lifting device mounted on the support 1 is a first electric push rod 2, which is connected to an external power source. Alternatively, other lifting devices, such as hydraulic cylinders, can be used instead of the first electric push rod 2; no further restrictions are imposed here. To increase the stability of the connection between the support 1 and the receiving plate 3, a telescopic rod 20 is distributed between the second sliding plate 17 and the receiving plate 3. When the first electric push rod 2 is working, the telescopic rod 20 extends and retracts under the action of the receiving plate 3, thus making the movement between the receiving plate 3 and the support 1 more stable.

[0023] Specifically, the clamping assembly 4 includes a first clamping plate 41 disposed on the tray 7, and second electric push rods 43 connected to an external power source are distributed on the top surface of the first clamping plate 41, with the telescopic ends of each second electric push rod 43 connected via the second clamping plate 42. Figure 1 and Figure 2 As shown, the second electric push rods 43 are distributed at the four corners between the first clamping plate 41 and the second clamping plate 42. By placing the second electric push rods 43 at the four corners of the first clamping plate 41 and the second clamping plate 42, the connection stability of the second clamping plate 42 relative to the first clamping plate 41 can be increased. When it is necessary to fix the discharge pipe to the clamping assembly 4, the discharge pipe can be inserted between the first clamping plate 41 and the second clamping plate 42 first, and then the second electric push rods 43 can be activated. The second electric push rods 43 drive the second clamping plate 42 down until the discharge pipe is clamped between the first clamping plate 41 and the second clamping plate 42. It should be noted that each second electric push rod 43 is connected through a controller, which facilitates the simultaneous operation of each second electric push rod 43 at the same speed and in the same direction, making the movement of the second clamping plate 42 more stable, and also making the clamping of the discharge pipe between the first clamping plate 41 and the second clamping plate 42 more stable.

[0024] Still Figure 2 As shown, an arc-shaped groove 5 is formed on the top surface of the first clamping plate 41, and a V-shaped bracket 6 is provided on the bottom surface of the second clamping plate 42. The arc-shaped groove 5 on the top surface of the first clamping plate 41 facilitates the placement and positioning of discharge pipes of different specifications and sizes, and the V-shaped bracket 6 on the bottom surface of the second clamping plate 42 can constrain the discharge pipe. This facilitates the clamping assembly 4 to quickly fix and disassemble discharge pipes of different sizes and specifications, improving the practicality of the gob-side retaining filling device.

[0025] like Figure 3As shown, the reciprocating device includes a support arm 10 mounted on the circumferential wall of the tray 7. The support arm 10 is arranged radially along the tray 7 and has a guide groove 14. A reciprocating mechanism is also provided on the receiving plate 3, which cooperates with the support arm 10. Specifically, the reciprocating mechanism includes a first motor 11 mounted on the receiving plate 3, which is connected to an external power supply. A mounting plate 12 is also provided on the output end of the first motor 11, and the center of the mounting plate 12 is connected to the output shaft of the first motor 11. An eccentric shaft 13 is provided on the top surface of one end of the mounting plate 12, and the eccentric shaft 13 is inserted into the guide groove 14. When the first motor 11 is working, it will drive the mounting plate 12 on its output end to rotate around the output shaft axis of the first motor 11. The eccentric shaft 13 set on the mounting plate 12 will also rotate around the output axis of the first motor 11. When the eccentric shaft 13 starts to rotate, it will drive the tray 7 to reciprocate through the support arm 10. Finally, the clamping component 4 set on the tray 7 will reciprocate, that is, the discharge pipe fixed on the clamping component 4 will reciprocate with the clamping component 4, thereby increasing the range of material flowing out of the discharge pipe.

[0026] As another preferred embodiment, a first groove 8 is formed on the receiving plate 3 near the reciprocating mechanism, and a first slide plate 9 is slidably disposed within the first groove 8, with a first motor 11 mounted on the first slide plate 9. A third electric push rod 81, connected to an external power source, is located within the first groove 8 and is connected to the first slide plate 9. The third electric push rod 81 can drive the first slide plate 9 to move within the first groove 8, thereby changing the position of the eccentric shaft 13 within the guide groove 14 of the support arm 10 via the mounting plate 12 and the first motor 11. This achieves the purpose of adjusting the amplitude of the reciprocating rotation of the pallet 7, adapting to adjustments in the rotation amplitude of the pallet 7 under different conditions, and further improving the practicality of the goaf-retaining filling device.

[0027] As a further improvement, a sliding assembly is provided on the support 1, and the lifting device is located on the sliding assembly. The sliding assembly allows the lifting device and its components to move along the length of the support 1, thereby controlling the insertion and withdrawal of the discharge pipe in the filling inlet, saving manual intervention and improving work efficiency. Specifically, the sliding assembly includes a second sliding groove 15 on the support 1, which penetrates the support 1. At both ends of the support 1 are baffles 16 that seal the two openings of the second sliding groove 15. The baffles 16 are detachably connected to the support 1 by screws. A screw 18 is rotatably mounted on the two baffles 16, penetrating the second sliding groove 15, and a second sliding plate 17 slides within the second sliding groove 15. The lifting device is located on the second sliding plate 17, and the screw 18 passes through and is threadedly connected to the second sliding plate 17. Additionally, a second motor 19, connected to an external power source, is located on the outer wall of one of the baffles 16, and the second motor 19 is connected to the screw 18. When the second motor 19 operates, it drives the screw 18 connected to it to rotate. The rotation of the screw 18 causes the second slide plate 17, which is threadedly connected to it, to slide within the second slide groove 15. As the second slide plate 17 slides, the components mounted on the second slide plate 17 via the lifting device also move accordingly, including the discharge pipe mounted on the clamping assembly 4. The second motor 19 can operate in both forward and reverse directions, thus enabling the screw 18 to rotate in both directions and allowing the second slide plate to reciprocate within the second slide groove 15.

[0028] Working principle: The discharge pipe is inserted into the gap between the first clamping plate 41 and the second clamping plate 42. Then, the second electric push rod 43 is activated, which lowers the second clamping plate 42 and clamps the discharge pipe between the first clamping plate 41 and the second clamping plate 42, thus fixing it in place. Next, the first electric push rod 2 is activated, which, through the receiving plate 3 and the tray 7, raises the discharge pipe on the clamping assembly 4 to the appropriate position. Then, the sliding device is activated, which, through the lifting device, moves the components on the lifting device and the discharge pipe towards the filling position until the discharge pipe is inserted into the inlet of the filling position, allowing the material to be filled.
