Description

Technical Field

[0001] This utility model relates to the field of guide rail installation technology, specifically to a guide rail installation hoist for tunnels. Background Technology

[0002] In underground engineering fields such as mines and tunnels, the installation quality of tunnel guide rails (such as monorail transport rails and auxiliary guide rails) directly determines the operational safety, stability, and efficiency of subsequent transportation equipment. Currently, tunnel guide rail installation mainly relies on traditional lifting tools or temporary on-site support structures, which faces many technical bottlenecks in practical applications and struggles to meet the requirements of modern underground engineering for installation accuracy, construction efficiency, and safety and reliability.

[0003] Underground tunnels present complex environments with significant variations in roof height and rock strata undulation. Furthermore, different projects have stringent requirements for the precision of guide rail installation elevation and levelness (e.g., monorail tracks must meet standards such as horizontal / vertical deviation ≤3mm and joint gap ≤5mm). Traditional lifting equipment is mostly of fixed dimensions, such as brackets welded from angle steel and channel steel. The top of the bracket has pre-set holes for connection to roof anchors, and the bottom has pre-set slots for connection to the guide rails. There are no adjustable components, making it impossible to flexibly adjust the length or height according to site conditions. If different tunnel dimensions need to be accommodated, multiple sets of specialized lifting equipment must be customized, increasing equipment costs and easily leading to insufficient guide rail installation precision due to dimensional mismatches. In addition, temporary support structures (such as scaffolding and simple chain hoists) lack fine-tuning capabilities, making it difficult to compensate for deviations caused by uneven roofs and construction errors. This often results in guide rail tilting, joint misalignment, and other problems, leading to equipment malfunctions, accelerated guide rail wear, and even increased safety hazards such as derailment and overturning. Utility Model Content

[0004] The present invention aims to provide a hoisting tool for installing guide rails in tunnels, thereby solving the problem that the hoisting tool in the prior art cannot be adjusted according to the actual installation situation.

[0005] To address the above problems, this application provides the following technical solution: A hoisting device for installing a roadway guide rail includes a hoisting base and symmetrically arranged hoisting components. The hoisting base is fixed with a horseshoe ring by bolts. The hoisting components include an anchoring plate, an anchoring rod, and an adjusting pipe. A fixing ring is installed at the end of the anchoring rod away from the anchoring plate. The adjusting pipe is symmetrically threaded with coaxial adjusting rods. A first screw threaded into the fixing ring is threaded at the end of the top adjusting rod away from the adjusting pipe. A second screw threaded into the horseshoe ring is threaded at the end of the bottom adjusting rod away from the adjusting pipe. The hoisting base and the guide rail are fixedly connected.

[0006] The working principle and beneficial effects of this utility model: The anchor plate in the lifting assembly is attached to the tunnel roof, and the entire lifting assembly is fixed to the roof by anchor rods. The two ends of the adjusting pipe are threaded to the top adjusting rod and the bottom adjusting rod, respectively, and are coaxially arranged. If it is necessary to increase the overall length of the lifting device, adapt to higher tunnels, or reduce the installation height of the guide rail, the adjusting rod can be rotated clockwise to extend the top or bottom adjusting rod outwards from the adjusting pipe. At the same time, the top adjusting rod is connected to the fixing ring of the anchor rod through the first screw, and the bottom adjusting rod is connected to the horseshoe ring of the lifting seat through the second screw. The lifting assemblies on both sides lift the guide rail upwards through the lifting seat.

[0007] Traditional lifting devices have a fixed structure and require multiple sets of equipment to be customized for different roadway heights and guide rail elevations; however, this lifting device can be flexibly adapted to different roadway conditions through the threaded connection of the adjusting pipe and adjusting rod (without the need to customize multiple sets), which greatly reduces equipment procurement and storage costs.

[0008] The combination of the top anchor plate and anchor rod provides stable support. The threaded connection between the adjusting pipe and the adjusting rod is self-locking (the length remains stable after adjustment without the need for additional fasteners). Furthermore, the connection structure between the lifting seat and the horseshoe ring can distribute the weight of the guide rail, avoiding fractures caused by local stress concentration. This structural design reduces safety hazards during installation.

[0009] Preferably, the inner circumferential surface of the adjusting tube is provided with an internal thread, and the outer circumferential surface of the adjusting rod is provided with an external thread adapted to the internal thread. When the adjusting tube is rotated, the internal thread and the external thread of the adjusting rod engage and transmit power. Since the adjusting tube and the adjusting rod are coaxially designed, no radial offset will occur during the transmission process.

[0010] As a preferred embodiment, the number of fixing rings is multiple, and the multiple fixing rings are interconnected.

[0011] As a preferred embodiment, it also includes another anchor plate located between the two sets of lifting components, the anchor plate being fixed with a connecting ring that passes through the horseshoe ring.

[0012] As a preferred embodiment, the number of connecting rings is multiple, and the multiple connecting rings are interconnected.

[0013] As a preferred embodiment, the lifting base and the guide rail are fixed by welding or bolting. Attached Figure Description

[0015] The reference numerals in the accompanying drawings include: top plate 1, anchor plate 2, fixing ring 3, anchor rod 4, U-shaped end 5, first screw 6, adjusting pipe 7, second screw 8, horseshoe ring 9, lifting seat 10, guide rail 11, connecting ring 12, and adjusting rod 13. Detailed Implementation

[0016] The following detailed description illustrates the specific implementation method: Reference Figure 1 , Figure 2 and Figure 3 This embodiment provides a roadway guide rail installation hoist, including a hoisting base 10 and symmetrically arranged hoisting components. The top of the hoisting base 10 is fixed with a horseshoe ring 9 by bolts, and the bottom of the hoisting base 10 is fixed with a guide rail 11 by welding.

[0017] The hoisting assembly includes an anchor plate 2, an anchor rod 4, and an adjusting pipe 7. The anchor plate 2 is anchored to the top plate 1 by the anchor rod 4. The bottom of the anchor rod 4 is provided with an installation hole for inserting the top fixing ring 3. In this embodiment, there are 3 fixing rings 3, which are interlocked with each other.

[0018] The adjusting tube 7 is symmetrically threaded with coaxial adjusting rods 13. The end of each adjusting rod 13 away from the adjusting tube 7 includes an integrally formed U-shaped end 5. The first screw 6 threaded to the U-shaped end 5 of the top adjusting rod 13 passes through the fixing ring 3 at the bottom. The U-shaped end 5 of the bottom adjusting rod 13 is threaded with a second screw 8 passing through the horseshoe ring 9. As a preferred method, in order to provide auxiliary fixation, another anchor plate 2 and four interconnected connecting rings 12 located between the two sets of hoisting components are also included. The top connecting ring 12 is fixedly welded to the anchor plate 2, and the bottom connecting ring 12 is connected to the horseshoe ring 9.

[0019] In addition, the fixing ring 3 and the connecting ring 12 are made of plastic materials such as iron or aluminum alloy. The broken ends are staggered by manual means and external tools (such as wrenches) to facilitate wrapping and connection, and then the broken ends are closed.

[0020] The anchor plate 2 in the hoisting assembly is attached to the roof 1 of the roadway. The entire hoisting assembly is fixed to the roof 1 by the anchor rod 4. The two ends of the adjusting pipe 7 are threadedly connected to the top adjusting rod 13 and the bottom adjusting rod 13, respectively, and are coaxially arranged. If it is necessary to increase the overall length of the hoisting device to adapt to higher roadways or to lower the installation height of the guide rail 11, the adjusting rod 13 can be rotated clockwise to extend the top adjusting rod 13 or the bottom adjusting rod 13 outward from the adjusting pipe 7. At the same time, the top adjusting rod 13 is connected to the fixing ring 3 on the anchor rod 4 by the first screw 6, and the bottom adjusting rod 13 is connected to the horseshoe ring 9 on the hoisting seat 10 by the second screw 8. The hoisting assemblies on both sides lift the guide rail 11 upward through the hoisting seat 10.

[0021] Secondly, the number and length of the connecting rings 12 are adjusted in accordance with the hoisting components on both sides.

[0022] Traditional lifting devices have a fixed structure and require multiple sets of equipment to be customized for different roadway heights and guide rail 11 elevations; however, this lifting device can be flexibly adapted to different roadway conditions through the threaded connection between the adjusting pipe 7 and the adjusting rod 13 (without the need to customize multiple sets), which greatly reduces equipment procurement and storage costs.

[0023] The combination of the top anchor plate 2 and the anchor rod 4 provides stable support. The threaded connection between the adjusting pipe 7 and the adjusting rod 13 has self-locking properties (the length can be kept stable without additional fasteners after adjustment). The connection structure between the lifting seat 10 and the horseshoe ring 9 can distribute the weight of the guide rail 11 and avoid fracture caused by local stress concentration. From the structural design, the safety hazards during installation are reduced.

[0024] It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model. These modifications and improvements should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
