Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal mining technology, and in particular to a flexible mold bag sealing device. Background Technology
[0002] Goaf retention technology refers to maintaining the original mining roadway along the edge of the goaf after the coal face. To recover the protective coal pillars left in traditional mining methods, certain technical means are used to re-support the roadway from the previous section for use in the next section. Goaf retention technology plays an increasingly important role in the construction of modern mines. During the construction of goaf retention support systems, the quality and effectiveness of the backfill material beside the roadway are always of paramount importance.
[0003] Flexible formwork bags are mainly made of polymer materials. As a new type of mine support material, they are characterized by high flexibility, good pressure resistance, and convenient installation. In goaf support, the working principle of flexible formwork bags is to form a support body by filling the material, providing stable support to the roof and sidewalls of the roadway, preventing rock collapse and roadway deformation.
[0004] When creating a roadway along the goaf, a certain width of roadway support structure needs to be installed along the edge of the goaf. This support structure is typically constructed by hanging flexible formwork bags and then pouring concrete. To ensure construction quality, concrete slurry at a certain pressure needs to be pumped to meet the roof. During pumping, the pressure can cause some substandard flexible formwork bags to rupture. Furthermore, improper operation by construction personnel can lead to slurry leakage or spillage accidents when filling the concrete. This results in a decrease in the quality of the roadway along the goaf, creating safety hazards, increasing labor intensity, and raising production costs. Utility Model Content
[0005] This utility model provides a flexible mold bag sealing device to solve the defects of the existing flexible mold bag that is prone to cracking, resulting in slurry leakage and spillage. It can seal the cracked position of the flexible mold bag, increase the quality of the goaf retention in the working face, and reduce the safety hazards of goaf retention.
[0006] This utility model provides a flexible mold bag sealing device, including a rubber ring, a fixing ring and a flexible mold cloth;
[0007] The rubber ring is located on the outer periphery of the fixing ring;
[0008] The flexible molding fabric is connected inside the rubber ring, and the fixing ring is connected to the rubber ring through the flexible molding fabric;
[0009] During operation, the retaining ring is connected to the flexible molded bag.
[0010] In addition, the flexible molded bag sealing device according to this utility model may also have the following additional technical features:
[0011] In some embodiments of this utility model, multiple slide bar assemblies are also included;
[0012] One end of each slide rod assembly is connected to a fixing ring, and the other end of each slide rod assembly is connected to a rubber ring; the central symmetry lines of multiple slide rod assemblies are coplanar.
[0013] In some embodiments of this utility model, multiple slide rod assemblies are arranged in a circular or rectangular array between the rubber ring and the fixing ring.
[0014] In some embodiments of this utility model, each slide rod assembly includes a first slide rod and a second slide rod;
[0015] The first slide rod and the second slide rod are slidably connected. The end of the first slide rod away from the second slide rod is connected to a rubber ring, and the end of the second slide rod away from the first slide rod is connected to a fixing ring.
[0016] In some embodiments of this utility model, the sum of the lengths of the first slide rod and the second slide rod is greater than the distance between the rubber ring and the fixed ring.
[0017] In some embodiments of this utility model, the retaining ring is made of steel or aluminum alloy.

[0022] This application includes the following beneficial technical effects: By using a combination of rubber rings, flexible mold cloth, and fixing rings, when a flexible mold bag ruptures, the rubber rings are gathered together and inserted into the ruptured flexible mold bag. The elasticity of the rubber rings allows them to open naturally, and the flexible mold cloth extends accordingly. After the rubber rings and flexible mold cloth of the flexible mold bag sealing device are attached to the flexible mold bag, the fixing ring is fixed to the flexible mold bag using wire or rope. Concrete material is then filled to ensure that the flexible mold bag sealing device is attached to the flexible mold bag, so that the flexible mold cloth seals the rupture, thereby achieving a sealing effect. This improves the quality of goaf-side roadway retention at the working face, reduces the safety hazards of goaf-side roadway retention, reduces labor intensity, and reduces production costs.

[0033] like Figures 1 to 3 As shown, according to an embodiment of the first aspect of the present invention, a flexible mold bag sealing device is proposed, including a rubber ring 11, a fixing ring 15 and a flexible mold cloth 12;
[0034] Rubber ring 11 is located on the outer periphery of fixed ring 15;
[0035] The flexible molding fabric 12 is connected inside the rubber ring 11, and the fixing ring 15 is connected to the rubber ring 11 through the flexible molding fabric 12;
[0036] During operation, the retaining ring 15 is connected to the flexible molded bag.
[0037] In the above embodiments, it should be noted that the rubber ring 11 is elastic, and the flexible fabric 12 is a flexible fabric made of the material used to make the flexible fabric bag. Specifically, it is made of high-strength, low-elongation synthetic fiber filaments such as polypropylene and polyester, and is manufactured using a special process. It has the advantages of being wear-resistant, puncture-resistant, anti-aging, acid and alkali resistant, and having high tensile strength.
[0038] Specifically, the flexible mold bag includes a flexible mold top 6, a main template 8, tie bolts 4, and a steel mesh 5. The top of the main template 8 is provided with a flexible mold top 6, and the outer periphery of the main template 8 is provided with a steel mesh 5 to fix the main template 8. Multiple tie bolts 4 are provided on the steel mesh 5. The main template 8 is connected to the steel mesh 5 through multiple tie bolts 4. The main template 8 is provided with a grouting port 2 and a reserved hole 3. The reserved hole 3 is a cylindrical structure prefabricated from the flexible mold cloth.
[0039] When the flexible mold bag ruptures, causing a rupture 7 in the main template 8, firstly, the rubber ring 11 of the flexible mold bag sealing device 1 is gathered together and inserted into the main template 8 through the rupture 7. Then, the rubber ring 11 naturally expands due to its elasticity, and the flexible mold cloth 12 extends accordingly. After the flexible mold bag sealing device 1 is attached to the inner wall of the main template 8 of the flexible mold bag, the fixing ring 15 is fixed to the steel mesh 5 of the flexible mold bag using iron wire, steel wire, or rivets. Then, concrete material is filled into the main template 8 of the flexible mold bag through the injection port 2 to make the rubber ring 11 of the flexible mold bag sealing device 1 fit with the main template 8 of the flexible mold bag, so that the flexible mold cloth 12 seals the rupture 7, thereby achieving the sealing effect.
[0040] The technical effects achieved by the above embodiments are as follows: the coordinated arrangement of the rubber ring 11, the flexible mold cloth 12, and the fixing ring 15 enables the rubber ring 11 to be gathered together when the flexible mold bag ruptures. After being stuffed into the ruptured flexible mold bag, the rubber ring 11 naturally opens due to its elasticity, and the flexible mold cloth 12 extends accordingly. After the rubber ring 11 and the flexible mold cloth of the flexible mold bag sealing device 1 are attached to the flexible mold bag, the fixing ring 15 is fixed to the flexible mold bag using wire or rope. The concrete material is then filled to make the flexible mold bag sealing device 1 fit with the flexible mold bag, so that the flexible mold cloth 12 seals the rupture 7, thereby achieving the sealing effect. This increases the quality of the goaf-side roadway retention at the working face, reduces the safety hazards of goaf-side roadway retention, reduces labor intensity, and reduces production costs.
