[0028] Example 1

[0029] like Figures 1-7 As shown:

[0030] A self-propelled, integrated sealing template device for dense filling coal mining includes a mobile integrated working platform 1, an integrated template 2, a lifting keel pipe 3, a self-sealing template 4, a template pushing and pulling hydraulic cylinder 5, a telescopic working platform hydraulic cylinder 7, a diagonal bracing hydraulic cylinder 8, a combined support column 12, and a hydraulic control system. The device can achieve sealing and reinforced support of filling roadways. Wherein:

[0031] The mobile integrated work platform 1 is a tracked platform used to support components such as templates, hydraulic cylinders, and combined supports. Besides a tracked structure, the mobile integrated work platform 1 can also be a mine car chassis type, wheeled type, or flatbed sliding type. In this embodiment, a tracked platform is selected to support templates, telescopic work platforms, hydraulic cylinders, combined supports, valve groups, etc.; the operating system includes a drive power and control system.

[0032] The integrated formwork 2 is made of several steel square or round tubes welded side by side. The bottom of the integrated formwork 2 is welded to the horizontal square tube. Its width is consistent with the width of the tunneling chamber, and its height is set according to the thickness of the coal seam.

[0033] The lifting keel pipe 3 is connected to the self-sealing template 4. The lifting keel pipe 3 is used to support the self-sealing template 4. As the lifting keel pipe 3 rises and falls, the self-sealing template 4 automatically seals the gaps between the lifting keel pipes 3 to ensure the sealing effect of the template.

[0034] The lifting keel pipe 3 is welded from steel square or round pipes corresponding to the number of integrated templates 2. The top of the lifting keel pipe 3 is welded to the horizontal square pipe. There are gaps between the lifting keel pipes 3, and the gap spacing is twice the wall thickness of the steel pipes of the integrated template 2. The lifting keel pipe 3 is inserted into the pipe of the integrated template 2, and the height of the lifting keel pipe 3 is set according to the thickness of the coal seam.

[0035] The self-sealing template 4 is a naturally hanging steel plate or alloy plate with T-shaped reinforcing ribs on the inside. The width of the self-sealing template 4 is the same as that of the integrated template 2, and the height of the integrated template 2 is the same as that of the lifting keel pipe 3. The upper part of the self-sealing template 4 is connected to the horizontal square tube at the top of the lifting keel pipe 3 by a hinge. The self-sealing template 4 rises and falls with the lifting keel pipe 3. The function of the self-sealing template 4 is to seal the gaps between the lifting keel pipes 3.

[0036] The template push-pull hydraulic cylinder 5 is used to push the extension and retraction of the lifting keel pipe 3, ensuring the precise positioning of the template between the top and bottom plates of the coal seam. The lower end of the cylinder body of the template push-pull hydraulic cylinder 5 is connected to the horizontal square tube at the bottom of the integrated template 2, and the upper end of the piston of the template push-pull hydraulic cylinder 5 is connected to the square tube at the top of the lifting keel pipe 3. When the piston of the template push-pull hydraulic cylinder 5 extends and retracts, it drives the lifting keel pipe 3 to move up and down inside the square tube of the integrated template 2. At the same time, the self-sealing template 4 also rises and falls with the lifting keel pipe 3. The template push-pull hydraulic cylinder 5 is set according to the width of the integrated template 2, and generally two to N cylinders can be set, such as... Figure 3 As shown, this embodiment is equipped with four template push-pull hydraulic cylinders 5.

[0037] The telescopic work platform 6 is positioned above the mobile integrated work platform 1 and is constrained by a U-shaped groove welded to the mobile integrated work platform 1. The function of the telescopic work platform 6 is to support the integrated template 2, the lifting keel pipe 3, the diagonal bracing hydraulic cylinder 8, and the connecting hinge 9, etc. Under the pushing and pulling of the telescopic work platform hydraulic cylinder 7, the telescopic work platform 6 can move horizontally.

[0038] The telescopic work platform hydraulic cylinder 7 is fixed in the middle of the mobile integrated work platform 1. The cylinder end on the mobile integrated work platform 1 is hinged to the mobile integrated work platform 1, and the piston end on the mobile integrated work platform 1 is hinged to the middle of the telescopic work platform 6. The telescopic work platform 6 is moved horizontally by pushing and pulling the telescopic work platform 6 through the telescopic work platform hydraulic cylinder 7 to ensure the stability of the template on the work platform.

[0039] The inclined hydraulic cylinder 8 is used to support the integrated template 2, ensuring a stable connection between the integrated template 2 and the coal seam floor. Depending on the width of the integrated template 2, two to N inclined hydraulic cylinders 8 can be installed. Figure 3 As shown, in this embodiment, two inclined support hydraulic cylinders 8 are provided. The lower end of the cylinder body of the inclined support hydraulic cylinder 8 is hinged to the telescopic work platform 6, and the upper end of the piston of the inclined support hydraulic cylinder 8 is hinged to the integrated template 2. The inclined support hydraulic cylinder 8 is used for telescopic support and retraction of the entire template.

[0040] Connecting hinge 9 is used to connect the telescopic work platform 6 and the integrated template 2. Both ends of connecting hinge 9 are hinged to the telescopic work platform 6 and the integrated template 2 respectively. Depending on the width of the integrated template 2, two to N connecting hinges 9 can be provided. Figure 3 In this embodiment, two connecting hinges 9 are provided. The two connecting hinges 9 are used to connect the telescopic work platform 6 and the integrated template 2, and are used to support and retract the entire template.

[0041] The bottom ends of the integrated template 2 are respectively provided with a lower hydraulic cylinder 10. The two lower hydraulic cylinders 10 are respectively installed at both ends of the horizontal square tube at the bottom of the integrated template 2. The lower hydraulic cylinders 10 are used to support the coal wall of the coal mining roadway, strengthen the support strength of the integrated template 2, and prevent it from falling back.

[0042] The top two ends of the lifting keel pipe 3 are respectively provided with an upper hydraulic cylinder 11. The two upper hydraulic cylinders 11 are respectively installed at both ends of the horizontal square tube at the top of the lifting keel pipe 3. The upper hydraulic cylinders 11 are used to hold the coal wall of the coal mining roadway, strengthen the support strength of the lifting keel pipe 3 and the self-sealing template 4, and prevent backward movement.

[0043] The combined support column 12 is composed of a hydraulic column 1201, a guide steel sleeve 1202, and a connecting steel beam 1203, providing support for the entire formwork system. Two to N combined support columns 12 can be installed depending on the required support strength. Figure 3 As shown, in this embodiment, five combined support pillars 12 are provided on the mobile integrated work platform 1 to support the mobile integrated work platform 1.

[0044] like Figure 7 As shown, each set of combined support columns 12 includes two hydraulic columns 1201, two guide steel sleeves 1202, and a connecting steel beam 1203. The upper ends of the two hydraulic columns 1201 are connected to the connecting steel beam 1203. Two guide steel sleeves 1202 (square or round) are provided between the connecting steel beam and the mobile integrated work platform 1. The upper ends of the inner tubes of the two guide steel sleeves 1202 are connected to the connecting steel beam 1203, and the lower ends of the outer tubes of the two guide steel sleeves are welded to the mobile integrated work platform 1. The function of the two guide steel sleeves is to support the two hydraulic columns and also to serve as guide tubes, so that the lower ends of the two hydraulic columns are away from the roadway floor, which facilitates the overall movement of the mobile integrated work platform 1.

[0045] The power and control system 13 of the mobile integrated work platform provides power and controls the movement of the entire platform. Power sources can include electricity, diesel engines, winches, etc.

[0046] The hydraulic control system 14 includes hydraulic valve groups, which can be single-piece valves, combination valves or solenoid valves. In this embodiment, a total of ten valve groups F1 to F10 are provided. Through the hydraulic valve groups F1 to F10, various hydraulic cylinders, such as template push-pull hydraulic cylinder 5, inclined brace hydraulic cylinder 8 and combination support column 12, are controlled to realize the support and retraction of the integrated template 2.

[0047] Fixed pin holes 16 of the same diameter are provided at corresponding positions on the mobile integrated work platform 1, the U-shaped groove, and the telescopic work platform 6. The fixed pin holes 16 are used to insert fixed pins 15. The function of the fixed pins 15 is to fix the telescopic work platform 6 to the mobile integrated work platform 1. When the telescopic work platform 6 is pushed into place, the fixed pins 15 are inserted into the corresponding fixed pin holes 16 to prevent the entire template system from moving backward under force.

[0048] This utility model relates to a self-propelled, integrated sealing template device used in the integrated mechanized unit compaction filling coal mining method. It achieves mechanized sealing of the template, simplifies the construction process, and reduces material consumption and worker labor intensity. It solves many problems existing in traditional template sealing methods, such as unstable support, high material consumption, high construction difficulty, and high worker labor intensity. At the same time, it improves work efficiency and safety through a hydraulic system and automated control.

[0049] This utility model of a self-propelled integrated sealing template device can be used independently. After the excavation of a filling face is completed, the power and control system 13 moves the two mobile integrated working platforms 1 to the two ends of the filling chamber, so that the integrated template 2 is supported at the entrance of the filling tunnel, thereby realizing the mechanized sealing of the filling tunnel.

[0050] The working steps of this utility model when sealing and filling tunnels are as follows:

[0051] First, manipulate F1 to inject the emulsion into the hydraulic cylinder 7 of the telescopic work platform. The piston of the hydraulic cylinder 7 of the telescopic work platform extends out from the cylinder body to push the telescopic work platform 6 to move, pushing the entire integrated template 2 (including the lifting keel pipe 3, self-sealing template 4, etc.) into the filling chamber opening.

[0052] The second step is to manipulate F2 to inject the emulsion into the inclined support hydraulic cylinder 8. The piston of the inclined support hydraulic cylinder 8 extends out of the cylinder body and pushes the integrated template 2 perpendicular to the top and bottom plates of the coal seam.

[0053] The third step is to manipulate F3 to inject the emulsion into the template push-pull hydraulic cylinder 5. The piston of the template push-pull hydraulic cylinder 5 extends out of the cylinder body to push the lifting keel pipe 3 out from the integrated template 2 until the top of the coal seam. At the same time, the self-sealing template 4 also rises as the lifting keel pipe 3 extends out, covering the lifting keel pipe 3, thereby sealing the gap between the lifting keel pipes 3.

[0054] Fourth step: manipulate F4 to inject the emulsion into the two lower hydraulic cylinders 10 of the integrated template 2. The piston of the lower hydraulic cylinder 10 extends from the cylinder body to support the left and right coal sides, which strengthens the support strength of the lower part of the template.

[0055] Fifth step, operate F5 to inject the emulsion into the two upper hydraulic cylinders 11 at the top of the lifting keel pipe 3. The piston of the upper hydraulic cylinder 11 extends from the cylinder body to support the left and right coal sides, which strengthens the support strength of the upper part of the template.

[0056] The above five steps complete the sealing of the filling chamber.

[0057] Step 6: Operate F6 to inject the emulsion into the hydraulic column of the combined support 12. The cylinder of the hydraulic column of the combined support 12 moves downward until it reaches the roadway floor. Then continue to inject the liquid. Under the pressure of the emulsion, the piston of the hydraulic column rises upward until it reaches the roadway roof. At the same time, the inner tubes of the two guide steel sleeves also extend upward. Continue to inject the liquid until the support strength is reached. Repeat operating F7, F8, F9, and F10 to make the other combined supports 12 reach the support strength.

[0058] Through the above steps, the sealing and reinforcement of the filling tunnel are completed, making the integrated formwork 2, lifting keel pipe 3, self-sealing formwork 4, and mobile integrated working platform more stable and solid. This ensures that the entire integrated formwork and mobile integrated working platform mechanism will not be washed away by the large impact force during the filling of paste. Then, the paste filling work can be carried out.

[0059] The self-propelled, integrated sealing template device of this invention is simple to operate, has a simple system, and provides good sealing effect, saving time and improving efficiency. Workers, in a safe environment with support, can control various hydraulic cylinders by manipulating the hydraulic valve group to support the template, reducing manual labor and the number of workers. The construction process is simple, eliminating the need for individual support pillars and heavy manual labor for template erection, ensuring worker safety. The template erection and sealing are fast, improving efficiency, increasing raw coal production, reducing the use of sealing auxiliary materials, and lowering raw coal costs.

[0060] After filling is completed using the self-moving integrated sealing template device of this utility model, and after the paste material has initially set, the template and the moving integrated working platform are retrieved. The steps are as follows:

[0061] First, manipulate F5 to inject the emulsion into the two upper hydraulic cylinders 11 at the top of the lifting keel pipe 3. The piston of the upper hydraulic cylinder 11 retracts into the cylinder body and moves away from the left and right coal sides.

[0062] The second step is to manipulate F4 to inject the emulsion into the two lower hydraulic cylinders 10 at the bottom of the integrated template 2. The piston of the lower hydraulic cylinder 10 retracts into the cylinder body and moves away from the left and right coal sides.

[0063] The third step is to manipulate F3 to inject the emulsion into the template push-pull hydraulic cylinder 5. The piston of the template push-pull hydraulic cylinder 5 retracts into the cylinder body. The retracted piston drives the lifting keel pipe 3 to retract into the integrated template 2, so that the lifting keel pipe 3 leaves the coal seam roof until it retracts into the integrated template 2. At the same time, the self-sealing template 4 also falls down with the retraction of the lifting keel pipe 3 until it returns to its original position.

[0064] Fourth step, manipulate F2 to inject the emulsion into the inclined support hydraulic cylinder 8. The piston of the inclined support hydraulic cylinder 8 retracts into the cylinder body. The retracted piston drives the integrated template 2 to tilt inward with the connecting hinge 9 as the fulcrum, so that the overall template detaches from the initially solidified paste and leaves the base plate until the overall template is reset.

[0065] Fifth step, manipulate F1 to inject the emulsion into the hydraulic cylinder 7 of the telescopic work platform. The piston of the hydraulic cylinder 7 of the telescopic work platform retracts into the cylinder body. The retracted piston drives the telescopic work platform 6 to move inward, and detaches the entire integrated template 2 (including the lifting keel pipe 3, self-sealing template 4, etc.) from the filling chamber opening.

[0066] Step 6: Operate F6, F7, F8, F9, and F10 respectively to retract the piston of the hydraulic column of the combined support 12 downwards. At the same time, the inner tubes of the two guide steel sleeves also retract downwards. After the connecting steel beam falls back to the top of the guide steel sleeve, the hydraulic column cylinder retracts upwards until the bottom of the hydraulic column cylinder leaves the tunnel floor. This completes one filling cycle.

[0067] This utility model solves the problems of the current practice of manually using single pillars, wooden boards, and plastic woven fabric (geotextile) to support formwork or using brick and stone walls for sealing when backfilling coal seam unit mining method. It realizes the mechanization of formwork sealing, solves the problems of difficulty in sealing with wooden boards and bricks and the difficulty in dismantling formwork, and solves the problem of excessive time for sealing with wooden formwork and bricks. It eliminates the risk of wooden formwork being washed away by the mortar during backfilling, eliminates the difficulty of operation and the risk of pillars falling and injuring people, and ensures the safety of workers.

[0068] This invention eliminates the need for large quantities of individual props, wooden planks, bricks, and other materials, reducing raw coal production costs, shortening support time, reducing the number of workers, and alleviating labor intensity. This invention also enables the repeated use of equipment, with the integrated template sealing device replacing individual props, wooden planks, bricks, and other materials, preventing grout burial, ensuring worker safety, reducing material consumption, saving material costs, and lowering production costs.

[0069] This invention provides a simple and easy-to-operate template sealing device with a concise system and excellent sealing effect. It eliminates the problem of template collapse caused by grout during filling, saving time, improving efficiency, and offering convenience, flexibility, stability, and safety. It also achieves rapid and efficient template installation and a high degree of connection with the coal seam roof and floor. The use of this device allows for simple and quick operation by workers, requiring only one person to operate the equipment. It frees coal miners from heavy physical labor, shortens the cycle time for grout filling in unit mining chambers, increases coal production, reduces overall costs, and improves the economic benefits of the enterprise.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
