Description

Technical Field

[0001] This utility model relates to the field of support structures, and in particular to a support structure for coal mining. Background Technology

[0002] Mine support netting, also known as coal mine weft and weft netting, coal mine protection netting, or coal mine safety netting, is a product with high tensile strength, a flat surface, and is sturdy and not easily pulled apart. Its safety factor meets national standards. Primarily used for artificial false roofs in coal mines, it reduces coal storage costs and saves on lead wire. It has become a key new technology promoted in my country's coal industry and is also being widely used in protective embankments, fencing for aquaculture, and other applications. It is now also a new type of material in the construction industry, functioning similarly to reinforcing steel. However, traditional mine support netting lacks localized reinforcement mechanisms due to its weakened structural strength in certain areas.

[0003] In existing technologies, such as the Chinese patent announcement CN221423207U entitled "A Coal Mine Mining Support Structure", which includes a support mesh, structural steel bars, side hanging rings, central hanging rings, and side structural reinforcement supports, the support mesh is installed by positioning and welding of structural steel bars, and side hanging rings and central hanging rings are installed at the side ends and center positions of the structural steel bars. Side structural reinforcement supports are installed based on the mesh surface of the support mesh. This device is designed for the local structural reinforcement design of the support mesh. L-shaped limit hooks are hung on the support mesh grid. The operating wrench tightens the threaded sleeve of the central rod and the threaded screw of the connecting rod to connect and install them. The traction spring performs elastic traction operation between the L-shaped limit hooks and the connecting rod. The left and right side structural reinforcement supports can be hung at any angle and position at the support mesh grid for structural reinforcement.

[0004] In the existing technology for installing and fixing support structures, the reinforcement rod components are fixed by structural steel bars. If the structural steel bars are loosely installed, the installation and fixing effect of the support mesh will be poor, which in turn will lead to poor practicality of the reinforcement rods.

[0005] Therefore, it is necessary to provide a coal mine mining support structure to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides a coal mine mining support structure, which solves the problem that when the reinforcement rod components are fixed by structural steel bars, the installation and fixing of the structural steel bars are relatively loose, which easily leads to poor installation and fixing effect of the support net, and thus poor practicality of the reinforcement rod.

[0007] To solve the above-mentioned technical problems, this utility model provides a coal mine mining support structure, including a No. 1 manual hydraulic column and a No. 2 manual hydraulic column. A pressure regulating cylinder is installed at the bottom of the side of the No. 1 manual hydraulic column, and a pressure rod is movably sleeved on the top of the pressure regulating cylinder. A No. 1 positioning column is fixedly connected to the side of the No. 1 manual hydraulic column, and a No. 1 buckle is fixedly connected to the side of the No. 1 positioning column. A reinforcing rod is movably sleeved inside the No. 1 buckle. A No. 2 positioning column is fixedly connected to the side of the No. 2 manual hydraulic column, and a No. 2 buckle is fixedly connected to the side of the No. 2 positioning column. A load-bearing sleeve is threaded onto the top of the No. 1 manual hydraulic column, and a rotating column is fixedly connected to the side of the load-bearing sleeve. A lifting seat is fixedly connected to the top of the load-bearing sleeve. A support column is movably sleeved onto the top of the No. 1 manual hydraulic column, and an anti-slip gear is fixedly connected to one end of the support column. An anti-slip mechanism is provided at the bottom of the No. 1 manual hydraulic column.

[0008] Preferably, the second buckle is movably sleeved on one end of the reinforcing rod, and there are several second buckles, which are evenly distributed on the side of the second positioning post.

[0009] Preferably, one end of the pressure rod is movably sleeved on the bottom of the side of the first manual hydraulic column, and there are two pressure rods.

[0010] Preferably, the support column is movably sleeved inside the lifting seat, and there are two support columns.

[0011] Preferably, there are two rotating columns, which are symmetrically distributed about the first manual hydraulic column as the axis of symmetry.

[0012] Preferably, the load-bearing sleeve is located directly below the lifting seat, and the load-bearing sleeve is compatible with the No. 1 manual hydraulic column.

[0013] Preferably, there are two anti-slip gears, and the two anti-slip gears are symmetrically distributed about the first manual hydraulic column as the axis of symmetry.

[0014] Preferably, the anti-slip mechanism includes a base plate, which is fixedly connected to the bottom of a first manual hydraulic column, and an anti-slip toothed plate is fixedly connected to the bottom of the base plate.

[0015] Preferably, the No. 1 positioning column and the No. 1 manual hydraulic column are parallel to each other, and the number of No. 1 positioning columns is four.

[0016] Compared with related technologies, the coal mine mining support structure provided by this utility model has the following beneficial effects:

[0017] This utility model provides a coal mine mining support structure. By setting a second buckle, when the support structure is installed and fixed, the first manual hydraulic column is extended, so that the first manual hydraulic column can support the mine tunnel. This allows the first and second manual hydraulic columns to be locked and fixed inside the mine tunnel. At this time, the two ends of the reinforcing rod are respectively sleeved inside the first and second buckles, so that the reinforcing rod can fix the first and second manual hydraulic columns, thereby improving the reinforcement and fixing effect of the mine tunnel load-bearing columns, that is, improving the reinforcement and fixing effect of the guardrail, thus avoiding the problem that poor fixing effect of the mine tunnel load-bearing columns leads to poor protection effect of the protective structure.

[0018] By setting a pressure rod, when the height of the No. 1 manual hydraulic column needs to be adjusted, the pressure regulating cylinder is pressed, which allows hydraulic oil to be injected into the interior of the No. 1 manual hydraulic column. This causes the No. 1 manual hydraulic column to move the support column up and down, thereby achieving the height adjustment effect of the No. 1 manual hydraulic column. This improves the adjustment effect of the support column's support height, thus bringing convenience to the support of mine tunnels at different heights. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of a coal mine mining support structure provided by this utility model; Figure 2 for Figure 1 The image shows a front view of a coal mine mining support structure. Figure 3 for Figure 1 The image shows a front view of a lifting seat in a coal mine mining support structure. Figure 4 for Figure 1 The image shows a front view of the No. 1 manual hydraulic column in a coal mine mining support structure. A coal mine mining support structure includes a first manual hydraulic column 1 and a second manual hydraulic column 2. A pressure regulating cylinder 3 is installed at the bottom of the side of the first manual hydraulic column 1, and a pressure rod 4 is movably sleeved on the top of the pressure regulating cylinder 3. A first positioning column 5 is fixedly connected to the side of the first manual hydraulic column 1, and a first buckle 6 is fixedly connected to the side of the first positioning column 5. A reinforcing rod 7 is movably sleeved inside the first buckle 6. A second positioning column 8 is fixedly connected to the side of the second manual hydraulic column 2, and a second buckle 9 is fixedly connected to the side of the second positioning column 8. A load-bearing sleeve 10 is threadedly sleeved on the top of the first manual hydraulic column 1, and a rotating column 11 is fixedly connected to the side of the load-bearing sleeve 10. A lifting seat 12 is fixedly connected to the top of the load-bearing sleeve 10. A support column 13 is movably sleeved on the top of the first manual hydraulic column 1, and an anti-slip gear 14 is fixedly connected to one end of the support column 13. An anti-slip mechanism 15 is provided at the bottom of the first manual hydraulic column 1.

[0026] The second clip 9 is movably sleeved on one end of the reinforcing rod 7. There are several second clips 9, which are evenly distributed on the side of the second positioning column 8. By setting the second clips 9, when the support structure is installed and fixed, the first manual hydraulic column 1 is extended, so that the first manual hydraulic column 1 can support the mine shaft. This allows the first manual hydraulic column 1 and the second manual hydraulic column 2 to be locked and fixed inside the mine shaft. At this time, the two ends of the reinforcing rod 7 are respectively sleeved inside the first clip 6 and the second clip 9, so that the reinforcing rod 7 can fix the first manual hydraulic column 1 and the second manual hydraulic column 2, thereby improving the reinforcement and fixing effect of the mine shaft load-bearing column, that is, improving the reinforcement and fixing effect of the guardrail, thus avoiding the problem that the poor fixing effect of the mine shaft load-bearing column leads to a poor protective effect of the protective structure.

[0027] One end of the pressure rod 4 is movably sleeved on the bottom of the side of the first manual hydraulic column 1. There are two pressure rods 4. By setting the pressure rods 4, when the height of the first manual hydraulic column 1 needs to be adjusted, the pressure regulating cylinder 3 is pressed, so that the pressure regulating cylinder 3 can inject hydraulic oil into the interior of the first manual hydraulic column 1, thereby causing the first manual hydraulic column 1 to drive the support column 13 to move up and down, thus achieving the height adjustment effect of the first manual hydraulic column 1, that is, improving the adjustment effect of the support height of the support column 13.

[0028] The support column 13 is movably sleeved inside the lifting seat 12, and there are two support columns 13. By setting the support columns 13, when the No. 1 manual hydraulic column 1 is installed and fixed, the two support columns 13 can support the top of the mine through the lifting seat 12, so that the weight of the rocks in the mine can be transferred to the inside of the No. 1 manual hydraulic column 1 through the two support columns 13, thereby achieving the support effect of the mine.

[0029] There are two rotating columns 11, which are symmetrically distributed about the first manual hydraulic column 1. By setting the rotating columns 11, when adjusting the unfolding angle of the support column 13, the rotating columns 11 can be manually rotated, so that the rotating columns 11 can drive the load-bearing sleeve 10 to rotate and lift, that is, drive the lifting seat 12 to move up and down, thus bringing convenience to the manual rotation adjustment of the load-bearing sleeve 10.

[0030] The load-bearing sleeve 10 is located directly below the lifting seat 12, and the load-bearing sleeve 10 is compatible with the first manual hydraulic column 1. By setting the load-bearing sleeve 10, when it is necessary to adjust the unfolding angle of the support column 13, the load-bearing sleeve 10 is rotated, so that the load-bearing sleeve 10 can drive the lifting seat 12 to move up and down, that is, drive the lifting seat 12 to fit onto the bottom of the support column 13, so that the lifting seat 12 can drive the support column 13 to retract and flip, thereby achieving the effect of adjusting the unfolding angle of the two support columns 13.

[0031] There are two anti-slip gears 14, which are symmetrically distributed about the first manual hydraulic column 1 as the axis of symmetry. By setting the anti-slip gears 14, when the mine is being supported and protected, the anti-slip gears 14 greatly increase the friction between the support column 13 and the inner wall of the mine, thereby avoiding the problem of the support column 13 sliding when the first manual hydraulic column 1 shakes, thus improving the stability of the support column 13.

[0032] The anti-slip mechanism 15 includes a base plate 151, which is fixedly connected to the bottom of the No. 1 manual hydraulic column 1. An anti-slip toothed plate 152 is fixedly connected to the bottom of the base plate 151. By setting the anti-slip mechanism 15, when the mine shaft is being supported and protected, the anti-slip toothed plate 152 greatly increases the friction between the No. 1 manual hydraulic column 1 and the ground, thus avoiding the problem that the bottom of the No. 1 manual hydraulic column 1 will slide due to uneven ground, which would lead to low stability of the No. 1 manual hydraulic column 1, thereby improving the stability of the support structure.

[0033] The No. 1 positioning column 5 and the No. 1 manual hydraulic column 1 are parallel to each other, and there are four No. 1 positioning columns 5. By setting the No. 1 positioning columns 5, when the support structure is installed and fixed, the two sets of No. 1 positioning columns 5 can position several No. 1 buckles 6, so that several No. 1 buckles 6 can connect the top of the reinforcing rods 7 on both sides of the No. 1 manual hydraulic column 1, thereby facilitating the connection and fixing of multiple No. 1 manual hydraulic columns 1.

[0034] The working principle of the coal mine mining support structure provided by this utility model is as follows:

[0035] Step 1: First, during the installation and fixing of the support structure, extend the No. 1 manual hydraulic column 1 to support the mine shaft. This allows the No. 1 and No. 2 manual hydraulic columns to be locked and fixed inside the mine shaft. At this time, the two ends of the reinforcing rod 7 are respectively fitted into the No. 1 clip 6 and the No. 2 clip 9, allowing the reinforcing rod 7 to fix the No. 1 and No. 2 manual hydraulic columns, thereby improving the reinforcement and fixing effect of the mine shaft's load-bearing columns, which in turn improves the reinforcement and fixing effect of the guardrail. This avoids the problem of poor protection effect of the protective structure due to poor fixing effect of the mine shaft's load-bearing columns. When it is necessary to adjust the height of the No. 1 manual hydraulic column 1, press the pressure regulating cylinder 3 to inject hydraulic oil into the pressure regulating cylinder 3. The first manual hydraulic column 1 is inserted into the interior, which allows the first manual hydraulic column 1 to drive the support column 13 to move up and down, thereby achieving the height adjustment effect of the first manual hydraulic column 1, that is, improving the adjustment effect of the support height of the support column 13. When the first manual hydraulic column 1 is installed and fixed, the two support columns 13 can support the top of the mine through the lifting seat 12, so that the weight of the rocks in the mine can be transferred to the interior of the first manual hydraulic column 1 through the two support columns 13, thereby achieving the support effect of the mine. When the unfolding angle of the support column 13 is adjusted, the rotating column 11 is manually rotated, which drives the load-bearing sleeve 10 to rotate and lift, that is, drives the lifting seat 12 to move up and down, thus bringing convenience to the manual rotation adjustment of the load-bearing sleeve 10.

[0036] Step 2: When adjusting the unfolding angle of support column 13, rotate the load-bearing sleeve 10, causing the load-bearing sleeve 10 to move the lifting seat 12 up and down. This causes the lifting seat 12 to engage with the bottom of support column 13, allowing the lifting seat 12 to retract and rotate the support column 13, thus achieving the effect of adjusting the unfolding angle of the two support columns 13. When providing mine support and protection, the anti-slip gear 14 greatly increases the friction between the support column 13 and the mine wall, preventing the support column 13 from sliding when the first manual hydraulic column 1 shakes, thereby improving the stability of the support column 13. When providing support and protection for mine tunnels, the anti-slip toothed plate 152 greatly increases the friction between the No. 1 manual hydraulic column 1 and the ground, preventing the bottom of the No. 1 manual hydraulic column 1 from sliding due to uneven ground, which would lead to low stability of the No. 1 manual hydraulic column 1. This improves the stability of the support structure. When the support structure is installed and fixed, the two sets of No. 1 positioning columns 5 can position several No. 1 buckles 6, allowing the No. 1 buckles 6 to connect the top of the reinforcing rods 7 on both sides of the No. 1 manual hydraulic column 1, thus facilitating the connection and fixing of multiple No. 1 manual hydraulic columns 1.

[0037] Compared with related technologies, the coal mine mining support structure provided by this utility model has the following beneficial effects:

[0038] By setting the second buckle 9, when the support structure is installed and fixed, the first manual hydraulic column 1 is extended, so that the first manual hydraulic column 1 can support the mine shaft. This allows the first manual hydraulic column 1 and the second manual hydraulic column 2 to be locked and fixed inside the mine shaft. At this time, the two ends of the reinforcing rod 7 are respectively sleeved inside the first buckle 6 and the second buckle 9, so that the reinforcing rod 7 can fix the first manual hydraulic column 1 and the second manual hydraulic column 2, thereby improving the reinforcement and fixing effect of the mine shaft load-bearing column, that is, improving the reinforcement and fixing effect of the guardrail, thus avoiding the problem that the poor fixing effect of the mine shaft load-bearing column leads to a poor protective effect of the protective structure.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
