Description

Technical Field

[0001] This utility model relates to the field of mine roadway support technology, and in particular to an I-beam installation device in a mine. Background Technology

[0002] As a key structure in underground mining, mine roadways extend in stages from main roadways to branch roadways, undertaking functions such as transportation, ventilation, and drainage. Their spatial form is designed as arched or rectangular according to geological conditions, and they are reinforced with technologies such as anchor bolt support and shotcrete to cope with complex environments such as high pressure and water seepage in deep wells. The purpose of roadway support is to control the deformation of the surrounding rock and prevent collapse. The effect is affected by many factors such as the properties of the surrounding rock, the mechanical characteristics of the support, the density and timing of installation, construction quality, and contact method.

[0003] When using shed-type supports for tunneling in mines, I-beam shed support systems are often used. However, during blasting operations at the tunneling face, the supported I-beam sheds often collapse due to impact, leading to an expansion of the open roof area in the tunnel. This not only creates a safety hazard but, in severe cases, can directly cause a safety accident, threatening the safety of underground workers and production order. Therefore, an I-beam installation device for mines is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies where, when using shed-type supports for mine tunneling, I-beam shed support systems are often used. However, during blasting operations at the tunneling face, the supported I-beam sheds often collapse due to impact, leading to an expansion of the open roof area in the tunnel. This not only creates a safety hazard but can also directly cause a safety accident in serious cases. Therefore, this utility model proposes an I-beam installation device for mine tunnels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mine shaft I-beam installation device includes two I-beams;

[0007] The mounting components are in quantity two and are positioned opposite each other on two I-beams. Each mounting component includes an L-shaped buckle sleeved and connected to the I-beam, a U-shaped connecting block one fixedly connected to the side of the L-shaped buckle, a transverse connecting rod movably connected to the U-shaped connecting block one via a shaft, a U-shaped buckle sleeved and connected to the transverse connecting rod, a U-shaped connecting block two fixedly connected to the upper surface of the U-shaped buckle, and an oblique connecting rod movably connected to the U-shaped connecting block two via a shaft and fixedly positioned with the I-beam.

[0008] Using the above solution, two I-beams can be quickly connected to each other through mounting components, and the connection between the two I-beams is made securely through the connection of transverse connecting rods and diagonal connecting rods, thereby improving the stability between the two I-beams.

[0009] In a preferred embodiment, the L-shaped buckle is threaded with a hexagonal head bolt, and a washer is fixedly connected to one end of the hexagonal head bolt and fits against the I-beam.

[0010] Using the above solution, the L-shaped buckle is tightly secured to the I-beam by rotating the hexagonal head bolt. The connection between the washer and the I-beam ensures that the L-shaped buckle is stably fixed to the I-beam.

[0011] In a preferred embodiment, the L-shaped buckle is shaped to facilitate fixing to the side of the I-beam away from the mine wall, and the end of the L-shaped buckle is provided with a locking block that fits tightly against the I-beam.

[0012] Using the above solution, the unused side of the L-shaped buckle is easy to install directly on the I-beam, and the connection between the L-shaped buckle and the I-beam is strengthened by the locking blocks arranged at the end of the L-shaped buckle.

[0013] In a preferred embodiment, the transverse connecting rod has several slots, the U-shaped buckle is fastened to the outside of the two transverse connecting rods, the U-shaped buckle has a horizontal through hole, and the same hexagonal head bolt II is inserted into the through hole and the two slots on the two transverse connecting rods. The hexagonal head bolt II is threaded with a nut II, and the two transverse connecting rods are connected to each other through the cooperation of the hexagonal head bolt II and the U-shaped buckle.

[0014] Using the above solution, the U-shaped buckle is placed directly on the two horizontal connecting rods and connected by hexagonal head bolts. The installation method is convenient and improves the connection stability between the two horizontal connecting rods.

[0015] In a preferred embodiment, a fixing plate is attached to the side of the I-beam, and an inner corner cylindrical bolt is inserted into the fixing plate and connected to the I-beam. The end of the inner corner cylindrical bolt is threaded with a nut. A U-shaped connecting block is fixedly connected to the side of the fixing plate near the inclined connecting rod. The U-shaped connecting block is movably connected to the inclined connecting rod via a shaft.

[0016] Using the above scheme, the oblique connecting rod is fixed to the I-beam by the inner corner cylindrical bolt, which improves the overall stability, and the connection position can be easily adjusted by the movable connection with the U-shaped connecting block three.

[0017] In a preferred embodiment, the oblique connecting rod is obliquely connected to the I-beam at the same side position through multiple slots on the transverse connecting rod.

[0018] Using the above scheme, the oblique connecting rod can be easily adjusted to a suitable connection position through the groove on the transverse connecting rod.

[0019] In a preferred embodiment, the two I-beams are connected to each other by a transverse connecting rod, and the diagonal connecting rod is connected to the transverse connecting rod and the I-beam to form a triangular shape.

[0020] By adopting the above scheme, the lateral connection of the two transverse connecting rods increases the lateral tensile force between the two I-beams, and the triangular shape connected by the diagonal connecting rods can effectively limit the displacement of the I-beams in and out of the plane, making the entire connection structure more stable and reducing swaying or instability caused by external forces.

[0021] This utility model has the following beneficial effects:

[0022] In this invention, the L-shaped buckle in the mounting component, along with a hexagonal head bolt and a washer, securely fastens to the I-beam, ensuring convenient installation and a tight connection. The transverse connecting rod is quickly connected via a U-shaped buckle and a hexagonal head bolt, enhancing the transverse tensile strength of the I-beam. The diagonal connecting rod has an adjustable connection position, forming a stable triangular structure with the transverse connecting rod and the I-beam, effectively limiting the displacement of the I-beam. The overall mounting component ensures a firm connection of the I-beam, improving support stability, reducing the risk of I-beam collapse caused by external forces such as blasting, and guaranteeing the safety of underground operations and production order.

[0028] like Figures 1-4 As shown, the present invention proposes a mine I-beam installation device, which includes two I-beams 1;

[0029] Mounting components 14, numbered in pairs and positioned opposite each other on two I-beams 1, include an L-shaped buckle 2 sleeved and connected to the I-beam 1, a U-shaped connecting block 1 5 fixedly connected to the side of the L-shaped buckle 2, a transverse connecting rod 6 movably connected to the U-shaped connecting block 1 5 via a shaft, a U-shaped buckle 7 sleeved and connected to the transverse connecting rod 6, a U-shaped connecting block 2 8 fixedly connected to the upper surface of the U-shaped buckle 7, and an oblique connecting rod 10 movably connected to the U-shaped connecting block 2 8 via a shaft and fixedly set with the I-beam 1. The two I-beams 1 can be quickly connected to each other through the mounting components 14, and the connection between the two I-beams 1 is firmly established through the connection of the transverse connecting rod 6 and the oblique connecting rod 10, thereby improving the stability between the two I-beams 1.

[0030] The L-shaped buckle 2 is threaded with a hexagonal head bolt 3. The end of the hexagonal head bolt 3 is fixedly connected to a washer 4 and fits against the I-beam 1. The L-shaped buckle 2 is tightly clamped onto the I-beam 1 by rotating the hexagonal head bolt 3. The connection between the washer 4 and the I-beam 1 makes the L-shaped buckle 2 stably fixed on the I-beam 1.

[0031] The shape of the L-shaped buckle 2 makes it easy to fix on the side of the I-beam 1 away from the mine wall. The end of the L-shaped buckle 2 is provided with a locking block that fits tightly with the I-beam 1. The open side of the L-shaped buckle 2 makes it easy to install directly on the I-beam 1. The locking block at the end of the L-shaped buckle 2 strengthens the connection between the L-shaped buckle 2 and the I-beam 1.

[0032] Several slots are provided on the transverse connecting rod 6. U-shaped buckles 7 are fastened to the outside of the two transverse connecting rods 6. A through hole is provided horizontally on the U-shaped buckle 7. The same hexagonal head bolt 29 is inserted into the through hole and the two slots on the two transverse connecting rods 6. A nut 1 is threaded onto the hexagonal head bolt 29. The two transverse connecting rods 6 are connected to each other through the cooperation of the hexagonal head bolt 29 and the U-shaped buckle 7. The U-shaped buckle 7 is placed directly on the two transverse connecting rods 6 and connected by the hexagonal head bolt 29. The installation method is convenient and improves the connection stability between the two transverse connecting rods 6.

[0033] A fixing plate 13 is attached to the side of the I-beam 1. An inner angle cylindrical bolt 12 is inserted into the fixing plate 13 and is connected to the I-beam 1. A nut is threaded to the end of the inner angle cylindrical bolt 12. A U-shaped connecting block 3 11 is fixedly connected to the side of the fixing plate 13 near the inclined connecting rod 10. The U-shaped connecting block 3 11 is movably connected to the inclined connecting rod 10 through a shaft. The inclined connecting rod 10 is fixed to the I-beam 1 by the inner angle cylindrical bolt 12, which improves the overall stability. The movable connection with the U-shaped connecting block 3 11 facilitates the adjustment of the connection position.

[0034] The oblique connecting rod 10 is obliquely connected to the I-beam at the same side position through multiple slots on the transverse connecting rod 6. The oblique connecting rod 10 is convenient to adjust to a suitable connection position through the slots on the transverse connecting rod 6.

[0035] The two I-beams 1 are connected to each other by a transverse connecting rod 6, and the diagonal connecting rod 10 is connected to the transverse connecting rod 6 and the I-beam 1 to form a triangular shape. The transverse connection of the two transverse connecting rods 6 increases the transverse tensile force between the two I-beams 1, and the triangular shape connected by the diagonal connecting rod 10 can effectively limit the displacement of the I-beams 1 in and out of the plane, making the entire connection structure more stable and reducing swaying or instability caused by external forces.

[0036] In this embodiment, the I-beam 1 is installed on one side of the inner wall of the mine, with one side of the I-beam 1 fitting against the mine wall. The open side of the L-shaped buckle 2 is fitted onto the I-beam 1. At this time, the hexagonal head bolt 3 on the L-shaped buckle 2 drives the washer 4 to fit against one side of the L-shaped buckle 2, facilitating the fitting of the L-shaped buckle 2 onto the I-beam 1. When fitting the L-shaped buckle 2, the end of the buckle is fitted against the protruding part on one side of the I-beam 1. Rotating the hexagonal head bolt 3 drives the washer 4 to fit against the I-beam 1, so that the L-shaped buckle 2 is clamped onto the I-beam 1. The L-shaped buckles 2 are fixed on two adjacent I-beams 1 on one side. At this time, the transverse connecting rods 6 on the two L-shaped buckles 2 are parallel to each other. At this time, the diagonal connecting rods 6 are... The connecting rod 10 is placed between the transverse connecting rod 6 and the I-beam 1 for position comparison. Once the position of the oblique connecting rod 10 is determined, a hole is drilled in the I-beam 1, and the fixing plate 13 is fixed to the I-beam 1 using the inner corner cylindrical bolt 12. In this way, one end of the oblique connecting rod 10 is fixed to the I-beam 1, and the other end of the oblique connecting rod 10 is fixed. The U-shaped buckle 7 is placed on the two parallel transverse connecting rods 6, and the hexagonal head bolt 2 9 passes through the U-shaped buckle 7 and the two transverse connecting rods 6, and is connected and fixed by the nut 1. In this way, the other end of the oblique connecting rod 10 is fixed to the two transverse connecting rods 6. In this way, the two I-beams 1 are stably connected by the transverse connecting rod 6 and the oblique connecting rod 10.
