Description

Technical Field

[0001] This utility model belongs to the technical field of tunnel steel support, and in particular relates to an adjustable high-strength steel support for tunnels. Background Technology

[0002] High-strength steel supports for roadways refer to supports made of high-strength steel used for roadway support. They are mainly used to provide stable support and strength to ensure the stability of the roadway.

[0003] According to a public disclosure (CN 221120031 U), an adjustable-angle, row-type self-moving support for roadways includes two identical row-type supports. Each row-type support includes at least two top beams and at least two support beams, arranged in a crisscross pattern with the top beams above the support beams. A telescopic support device is located below the row-type supports. The two row-type supports are spaced apart, with the top beams alternating. A hydraulic propulsion cylinder is installed between adjacent support beams to propel the two row-type supports forward relative to each other. Each telescopic support device on both sides has a hinge mechanism at its top facing the support beam. Both ends of each support beam are hinged to the corresponding telescopic support device via the hinge mechanism. In this invention, the support beams and telescopic support devices are hinged together, facilitating adjustment of the support beam's tilt angle. This allows the support beams to adapt to constantly changing tilted roof angles, increasing the application scenarios of the row-type self-moving support for roadways.

[0004] However, in the aforementioned application, the use of components such as row-type supports, top beams, supporting beams, and hydraulic propulsion cylinders makes it difficult to adjust the equipment according to the height of the roadway, which reduces the equipment's scope of application. Furthermore, the equipment cannot be fixed after the height is adjusted, resulting in instability during use and failing to ensure the safety of roadway construction. This aspect needs improvement. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable high-strength steel support for roadways. By configuring components such as an electric telescopic rod, a thrust plate, a force-bearing plate, a sliding groove, and a slider within the adjustment device, the electric telescopic rod extends and retracts, causing the thrust plate to move up and down. The up-and-down movement of the thrust plate causes the force-bearing plate to move up and down, which in turn causes the support and slider to slide up and down within the sliding groove. The up-and-down movement of the support causes the U-shaped steel frame to move up and down. This movement of the support and U-shaped steel frame adjusts the device, achieving the desired adjustment effect. This allows for adjustment according to the roadway height, enabling support for different arched roadways, ensuring roadway construction safety, and solving existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

The four installation ports are provided to make the equipment more securely fixed underground. The two sets of installation plates, hollow pillars, and supports are provided to support the roadway. The two sets of support plates, electric telescopic rods, thrust plates, and force-bearing plates are provided to adjust both sides.

[0011] Furthermore, a fixing device is provided on the side of the hollow support column. The fixing device includes a first threaded hole, which is opened on the side of the hollow support column. A threaded rod is threadedly connected inside the first threaded hole. A second threaded hole is opened on the side of the support column.

[0015] 1. This utility model, through the coordinated operation of components such as an electric telescopic rod, a thrust plate, a force-bearing plate, a sliding groove, and a slider within the adjustment device, achieves the following: when the electric telescopic rod extends or retracts, it drives the thrust plate to move up and down; the up and down movement of the thrust plate causes the force-bearing plate to move up and down; the up and down movement of the force-bearing plate causes the support and slider to slide up and down within the sliding groove; the up and down movement of the support causes the U-shaped steel frame to move up and down; and the up and down movement of the support and U-shaped steel frame adjusts the device, achieving the desired adjustment effect. This allows for adjustment according to the height of the roadway, enabling support for different arched roadways and ensuring roadway construction safety.

[0016] 2. This utility model, through the coordinated arrangement of components such as a first threaded hole, a threaded rod, a second threaded hole, a fixed plate, and a rotating handle within the fixing device, achieves a situation where rotating the handle drives the fixed plate to rotate, which in turn drives the threaded rod to rotate. When the threaded rod rotates, it moves to the left within the first threaded hole, and then into the second threaded hole. This effectively fixes the adjusted equipment, ensuring its stability during use and guaranteeing personnel safety and smooth construction.

[0033] A specific application of this embodiment is as follows: The user installs and fixes the device in the tunnel through the mounting port 2 on the mounting plate 1. After installation, the user can adjust the device according to the tunnel height using the adjustment device 6. The user activates the electric telescopic rod 62. When the electric telescopic rod 62 extends, it drives the thrust plate 63 upward. The upward movement of the thrust plate 63 pushes the force plate 64 upward. When the force plate 64 moves upward, it drives the bracket 4 and the slider 66 to slide upward within the slide groove 65. The upward movement of the bracket 4 drives the U-shaped steel... When frame 5 moves upward, the upward movement of both support 4 and U-shaped steel frame 5 will adjust the height of the equipment. When the electric telescopic rod 62 retracts, it will drive the thrust plate 63 to move downward. The downward movement of the thrust plate 63 will not obstruct the force plate 64. When the force plate 64 is unobstructed, it will move downward. The downward movement of the force plate 64 will drive support 4 and slider 66 to move downward in the slide 65. The downward movement of support 4 will drive U-shaped steel frame 5 to move downward. The downward movement of both support 4 and U-shaped steel frame 5 will adjust the height of the equipment. The equipment can be adjusted according to the height of the roadway.

[0034] After the equipment is adjusted, the adjusted height needs to be fixed to make the equipment more stable during use. The user uses the fixing device 7 and inserts the threaded rod 72 into the corresponding first threaded hole 71 according to the adjusted height. When the threaded rod 72 is in the first threaded hole 71, the user holds the rotating handle 75 and rotates the rotating handle 75 clockwise. The clockwise rotation of the rotating handle 75 will drive the fixing plate 74 to rotate clockwise, which will drive the threaded rod 72 to rotate clockwise. When the threaded rod 72 rotates clockwise, it will move to the left in the first threaded hole 71. At the same time, the threaded rod 72 moves to the left in the first threaded hole 71 and then moves to the second threaded hole 73, thus fixing the equipment with the adjusted height.
