Description

Technical Field

[0001] This utility model belongs to the field of paste filling technology, specifically a paste filling end sealing bracket. Background Technology

[0002] Green mining of coal resources is the future development direction and an effective method to reduce coal resource waste, extend the production life of coal mines, and reduce environmental damage. Among these methods, paste backfilling technology is an important component of the green mining system and has the widest range of applications.

[0003] Currently, efficient sealing of the end of the paste filling working face is one of the factors restricting filling efficiency. Especially for working faces with large inclination angles, the lateral pressure of the paste at the machine head end is high. The commonly used sealing method of single hydraulic support + baffle is prone to paste leakage accidents, posing a significant safety hazard. In addition, this method is labor-intensive and inefficient in disassembling and sealing, affecting the filling operation of the working face.

[0004] The existing technology disclosure number CN 113202554 A discloses an end-sealing support for coal mine paste filling. The end-sealing of the paste filling working face mainly uses a single prop + baffle form, both of which require manual disassembly and assembly of the baffle and handling of the single prop. This is time-consuming, labor-intensive, involves repetitive work by workers, and results in low sealing efficiency, failing to meet the requirements of working face automation. For working faces with large inclination angles, the lateral force of the paste at the machine head end is large, and the support of a single prop alone is insufficient to guarantee the sealing strength, easily leading to paste leakage accidents and posing safety hazards.

[0030] Example 1

[0031] Reference Figures 1-6 This embodiment provides an end-capping bracket for paste filling, comprising:

[0032] The components include a baffle body 1, a base 2, a support jack 3, a connecting rod 4, and a baffle jack 5. The two ends of the connecting rod 4 are hinged to the top of the baffle body 1 and the base 2, respectively. The two ends of the support jack 3 are hinged to the connecting rod 4 and the base 2, respectively. The baffle jack 5 is connected to the bottom of the baffle body 1 and the middle of the connecting rod 4.

[0033] It should be noted that the connecting rod 4 and the supporting jack 3 are connected to both sides of the base 2 respectively. The connecting rod 4 is close to the hinge point of the baffle body 1 and the supporting jack 3. Therefore, the connecting rod 4, the base 2, and the supporting jack 3 form a triangular structure. The length of the supporting jack 3 is adjustable. During the adjustment process, the connecting rod 4 rotates around the hinge point with the base 2 as the center. The other end of the connecting rod 4 drives the baffle body 1 to rotate. Figure 2 The left and right movement shown is used to adjust the position of the baffle body 1.

[0034] The baffle jack 5, connecting rod 4, and baffle body 1 also form a triangular structure. The length of the baffle jack 5 is adjustable and is used to adjust the angle of the baffle body 1.

[0035] The connecting rod 4 has a first lug 41 on one side and a second lug 42 on the other side. The end of the support jack 3 is connected to the first lug 41 by a pin, and the second lug 42 is connected to the end of the baffle jack 5 by a shaft.

[0036] A column 6 is installed on the base 2, and a top beam 7 is installed on the top of the column 6.

[0037] The column 6 is vertically mounted on the base 2, and the bottom of the column 6 is fixedly connected to the base 2.

[0038] The back of the baffle body 1 is provided with an upper telescopic jack 8, the top of the upper telescopic jack 8 is provided with an upper telescopic beam 9, and the bottom of the upper telescopic beam 9 is provided with a first guide rod 91, which is embedded inside the baffle body 1.

[0039] It should be noted that the top of the baffle body 1 has a vertically arranged groove structure, which cooperates with the first guide rod 91 to guide the first guide rod 91 so that the upper telescopic beam 9 can maintain vertical movement when the upper telescopic jack 8 is activated.

[0040] The back of the baffle body 1 is also provided with a lower telescopic jack 10, the bottom of the lower telescopic jack 10 is provided with a lower telescopic beam 11, and the bottom of the lower telescopic beam 11 is provided with a second guide rod 111 embedded inside the baffle body 1.

[0041] It should be noted that the bottom of the baffle body 1 has a vertically arranged groove structure, which cooperates with the second guide rod 111 to guide the second guide rod 111 so that the lower telescopic beam 11 can maintain vertical movement when the lower telescopic jack 10 is activated.

[0042] The back of the baffle body 1 is provided with a third hanging ear 12 and a fourth hanging ear 13, and the end of the connecting rod 4 is provided with a first hinge hole 43 and the other end is provided with a second hinge hole 44.

[0043] The third lug 12 is connected to the first hinge hole 43 by a pin, and the fourth lug 13 is connected to the other end of the baffle jack 5 by a pin.

[0044] It should be noted that the base 2 is also equipped with a Gael structure, which is connected to the second hinge hole 44.

[0045] The base 2 has a slot in the middle, in which a push rod 21 and a moving jack 22 are installed. One end of the moving jack 22 is hinged to the base 2, and the other end is hinged to the tail of the push rod 21.

[0046] The base 2 is also equipped with a bottom lifting jack 23, and the push rod 21 is equipped with a slide rail 211. The top of the bottom lifting jack 23 is fixed to the base 2, and the bottom is set in the slide rail 211.

[0047] Specifically, in response to the problem of end sealing of the paste filling working surface, this utility model provides an end sealing bracket for paste filling. The bracket mainly consists of a baffle body 1 for sealing, an upper telescopic beam 9, a lower telescopic beam 11, an upper telescopic jack 8, a lower telescopic jack 10, a support jack 3, a baffle jack 5, a connecting rod 4, a base 2, a column 6, and a top beam 7.

[0048] When the support system is used for sealing operations, the support column 6 is first raised until the top beam 7 contacts the roof, which helps maintain the stability of the support system and supports the roof. Then, the support jack 3 extends to move the baffle mechanism towards the roadway side. The angle of the baffle mechanism can be adjusted by extending and retracting the baffle jack 5 to ensure it remains perpendicular to the ground. Finally, the upper telescopic jack 8 extends, driving the upper telescopic beam 9 until it contacts the roadway roof, and the lower telescopic jack 10 extends, driving the lower telescopic beam 11 until it contacts the floor. This completes the sealing of the end area to be filled. During goaf filling, the support column 6 supports the roof, ensuring the stability of the support system, and the support jack 3 diagonally supports the baffle device to resist some of the lateral force of the slurry.

[0049] When moving the support frame after the sealing operation, first retract the upper telescopic beam 9 and the lower telescopic beam 11 to disengage from the roadway roof and floor. Then, use the support jack 3 to retract and move the baffle device towards the support side. At this time, the center of gravity of the support changes from the outside of the base 2 to above the base 2. Finally, lower the column 6, and the top beam 7 disengages from the roadway roof. Use the bottom lifting jack 23 to lower it into the slide 211 to lower the front end of the base 2 ( Figure 1 The left side is lifted, and the pusher jack 22 is pushed out, causing the push rod 21 to retract into the slot, pulling the entire support forward. Figure 1 Move to the left side, and the front end of push rod 21 connects to the front end bracket (not shown in the figure).

[0050] Furthermore, the end-sealing support is supported by two columns to maintain the stability of the support, while the contact friction between the support and the top and bottom plates of the roadway resists the lateral force of the slurry.

[0051] The support frame is moved by support jacks and baffle jacks. The support jacks can adjust the position of the baffle device and also provide diagonal bracing for the baffle device. The baffle jacks can adjust the angle of the baffle device to ensure that the baffle is perpendicular to the tunnel floor.

[0052] The baffle device is equipped with upper and lower telescopic beams to achieve sealing of the grouting area;

[0053] The supporting jack, base, and connecting rod can form a four-bar linkage to ensure the stability of the baffle device's movement.

[0054] Specifically, the present invention is equipped with an upper telescopic beam 9 and a lower telescopic beam 11 to achieve sealing of the top and bottom plates of the roadway.

[0055] The baffle device of the present invention is not directly connected to the base 2, and the position of the baffle device can be adjusted by the support jack 3.

[0056] This invention uses a supporting jack 3 to drive the movement of a four-bar linkage structure consisting of the supporting jack 3, base 2, and connecting rod 4, thereby adjusting and maintaining the stability of the baffle. Simultaneously, the baffle jack 5 adjusts the tilt angle of the baffle device. This invention uses two columns 6 to support the roof, both supporting the tunnel roof and providing sufficient friction to ensure the stability of the support. A pushing mechanism is provided on the base 2, with a push rod 21 connected to the front end support; the support moves forward by extending or retracting the pushing jack 22. It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring extensive experimentation.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
