[0003] In summary, how to provide a novel monorail suspension device that can solve the above-mentioned technical problems is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a new type of monorail suspension device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A novel monorail suspension device includes an I-beam and a bracket structure. Multiple upper thick steel plates are provided on the lower surface of the I-beam, and a lower thick steel plate is welded to the lower end of each upper thick steel plate. A connecting steel column is welded to one side of the lower thick steel plate. Multiple fully threaded anchor rods are installed in through holes on the surface of the upper thick steel plates, and anti-loosening nuts are provided on the outer surface of each fully threaded anchor rod. Multiple side-mounted anchor rods are installed in through holes on one side of the lower thick steel plate.

[0008] On the other hand, a connecting rod is welded to one end of the track suspension point relative to the I-beam.

[0009] On the other hand, a U-shaped rocker arm is welded to one end of the connecting rod relative to the track suspension point.

[0010] On the other hand, multiple lower fixing rods are welded to the inner surface of the U-shaped rocker arm.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] The core of this utility model is to provide a novel monorail suspension device, which will be discussed below. Figures 1-4 A detailed description of each component that makes up the suspension device is provided below:

[0026] This novel monorail hoisting device includes an I-beam 1 and a bracket structure. Multiple upper thick steel plates 2 are mounted on the lower surface of the I-beam 1. A lower thick steel plate 3 is welded to the lower end of the upper thick steel plate 2. A connecting steel column 4 is welded to one side of the lower thick steel plate 3. Multiple fully threaded anchor rods 5 are installed in through holes on the surface of the upper thick steel plate 2. Anti-loosening nuts 6 are installed on the outer surface of the fully threaded anchor rods 5. Multiple side-mounted anchor rods 7 are installed in through holes on one side of the lower thick steel plate 3. The bracket is welded from the thick steel plate and fixed to the side of the I-beam 1 using fully threaded anchor rods 5. The bracket supports the I-beam 1 and suspends the monorail hoisting track. The height of the upper surface of the bracket from the base plate is determined according to the monorail locomotive transportation requirements, ensuring the normal installation and safe transportation of the monorail hoisting track. Preferably, the thickness of the thick steel plate is 10mm, and the fully threaded anchor rods are preferably φ22×2200mm. In this context, the corbel structure, welded from 10mm thick steel plates, possesses high strength and rigidity, providing a stable support foundation for the upper I-beams and tracks. Compared to the single-point load-bearing mode of traditional suspension methods that rely on roof anchorage, the corbel, through the integration of a large-area steel plate with the roadway sidewall, distributes the track load to the sidewall rock mass, reducing local stress concentration. It is particularly suitable for complex roadway environments with poor roof rock properties, fragility, or grade-separated structures, avoiding the risk of track swaying or falling due to insufficient roof load-bearing capacity.

[0027] On the other hand, multiple track suspension points 8 are welded to the upper surface of the I-beam 1; specifically, the track suspension points 8 are used to fix the monorail track and are the core of the connection between the track and the upper suspension structure, ensuring that the track is stably suspended and bears the transport load.

[0028] On the other hand, a connecting rod 9 is welded to one end of the track suspension point 8 relative to the I-beam 1; specifically, the connecting rod 9 connects the track suspension point 8 and the U-shaped rocker arm 10, transmits tension or pressure, coordinates the force on each component, and ensures the overall stability of the suspension system.

[0029] On the other hand, a U-shaped rocker arm 10 is welded to one end of the connecting rod 9 relative to the track suspension point 8; specifically, the U-shaped rocker arm 10 flexibly adjusts the track angle through the arc structure to adapt to the undulation or turning scenarios of the tunnel, avoids stress concentration caused by rigid track connection, and improves the smoothness of operation.

[0030] On the other hand, multiple lower fixing rods 11 are welded to the inner surface of the U-shaped rocker arm 10. The lower fixing rods 11 fix the lower end of the hoisting chain and connect to the track hanging point to transfer the track load to the chain, while limiting the horizontal displacement of the track and ensuring the stability of the vertical force.

[0031] On the other hand, a hoisting chain 12 is provided on the outer surface of the lower fixed rod 11; specifically, the hoisting chain 12 bears the weight of the track and the transport equipment, buffers vibration through flexible connection, adapts to tunnel deformation, and is the main force transmission component between the upper and lower structures.

[0032] On the other hand, an upper fixing rod 13 is provided at one end of the hoisting chain 12 relative to the lower fixing rod 11; specifically, the upper fixing rod 13 fixes the upper end of the hoisting chain, connects the hoisting seat and the chain, and transfers the load to the roadway sidewall or roof to ensure a reliable connection between the upper anchoring structure and the chain.

[0033] On the other hand, lifting seats 14 are welded to both ends of the upper fixing rod 13; specifically, the lifting seats 14 serve as connecting components of the upper anchoring structure, providing basic support points for the entire suspension system.

[0034] On the other hand, an upper connecting hanging plate 15 is welded to the upper end of the lifting base 14. Specifically, the upper connecting hanging plate 15 expands the stress area, disperses the load borne by the lifting base, and enhances the strength and stability of the connection part.

[0035] On the other hand, the upper surface of the upper connecting hanging plate 15 has through holes for multiple lifting anchor rods 16; specifically, the lifting anchor rods 16 anchor the lifting seat or bracket structure to the rock mass of the roadway sidewall, and use the rock mass anchoring force to provide the lifting system with pull-out resistance, which is the fundamental guarantee for structural stability.

[0036] In summary: Thick steel plates are welded into a corbel structure, which is fixed to the side of the I-beam 1 using fully threaded anchor bolts 5. The corbel supports the I-beam 1, and the monorail is suspended from it. The height of the corbel's upper surface from the bottom plate is constructed according to the monorail locomotive's transportation requirements, ensuring the monorail can be installed and transported safely. The corbel structure, welded from thick steel plates, possesses high strength and rigidity, providing a stable support foundation for the upper I-beam and track. Compared to the single-point load-bearing mode of traditional suspension methods that rely on roof anchorage, the corbel, through the combination of a large-area steel plate and the roadway sidewall, distributes the track load to the sidewall rock mass, reducing local stress concentration. This is particularly suitable for complex roadway environments with poor roof rock properties, easy breakage, or grade-separated structures, avoiding the risk of track swaying or falling due to insufficient roof load-bearing capacity.
