Description

Technical Field

[0001] This invention relates to the field of monorail technology, and more particularly to the field of monorail tracks, specifically to a T-shaped arc-shaped press-fit suspension structure and installation method for a monorail track. Background Technology

[0002] Monorail locomotives, as an auxiliary transportation equipment in coal mines, have advantages such as high safety, strong driving force, strong adaptability, small space occupation, and high transportation efficiency. They are widely used in narrow spaces such as roadways and mine shafts and are suitable for most coal mines in my country. A monorail locomotive is a device that relies on an explosion-proof diesel engine or battery for power and can move along a track suspended above the roadway or mine shaft. The entire monorail transportation line is formed by connecting multiple fixed-length tracks. At the joint of two adjacent tracks, there are hanging accessories. Conventionally, the hanging accessories are welded to the track, and then the track is suspended from the roadway roof or other structures (such as miner's steel or U-shaped steel) in a certain way. Monorail tracks serve two key functions: first, reliable connection, including a secure connection between tracks and a smooth transition between them, ensuring the stability of the locomotive's passage. This effectively improves transportation efficiency and extends the service life of the monorail locomotive, preventing accidents such as locomotive damage due to unreliable track connections. Second, stable suspension, ensuring transportation safety and preventing the locomotive from falling off the tracks and causing injury to equipment and personnel. Therefore, the connection and suspension installation methods of monorail tracks directly determine the quality of track installation, thus affecting the safety and stability of the monorail locomotive's operation.

[0003] Monorail locomotives mainly rely on rails suspended from the roof of tunnels for transportation operations. Therefore, the locomotive is essentially directly suspended from the roof of the tunnel. Ensuring safe transportation is a key aspect of the entire safe transportation system of monorail locomotives. Research has found that the connection structure and installation method of the monorail rails play a crucial role in the efficient and safe transportation of the locomotive.

[0004] The commonly used heavy-duty monorail connection and suspension structure Figure 11-14As shown, the track is suspended using anchor bolts (cables). First, anchor bolts (cables) are driven into the tunnel roof for anchoring. Suspension accessories are welded to both ends of the track. Shackles, chains, and other suspension accessories are used to connect to the welded track accessories, thus completing the track connection and suspension. This track installation method accounts for over 80% of all track installation methods and is considered a conventional installation method. The advantage of this method is its flexible installation. The tracks are connected using tongue springs, and the rocker arm and figure-eight ring have a certain amount of room to move. Therefore, when the monorail crane is running, there is a certain gap redundancy between the tracks, preventing problems such as track squeezing and torsion. The invention patent with authorization announcement number CN101102950B, "Hinged Rail Conductor for Rail Joints of Profile Tracks," also discloses this suspension structure.

[0005] Disadvantages of the existing structure:

[0006] ① The track suspension accessories are numerous, including rocker arms, figure-eight rings, tongue springs, bolts, and different types of pins and safety pins. The installation requires a certain connection sequence, which places high demands on the technical skills of the installers. The installation is time-consuming and labor-intensive, which will increase the cost of parts and labor.

[0007] ② Adopt existing methods, such as Figure 14 As shown, when using the minimum 3-ring chain hoist, the height of the top plate from the bottom of the track is about 620mm to 650mm, which occupies a large space. If a low roadway is encountered, the mine needs to perform roof lifting or bottom laying treatment on the roadway, which increases the amount of construction work and is not conducive to the implementation of the monorail auxiliary transportation system.

[0008] ③ In this method, the correct installation position of the horizontal and rear pull of the track used to prevent swaying is as follows: the common installation method is to use shackle bolts at the small rocker arm and chain suspension point to increase the suspension point for horizontal and rear pull. However, this method has obvious disadvantages, namely that the small rocker arm can rotate along the figure-eight ring, which causes the horizontal and rear pull chains to sway, and the original function is invalidated.

[0009] The above track connection structures and installation methods have been used in the industry for many years without significant technological improvements. However, with the optimization of monorail assisted transportation systems and the diversification of application scenarios, especially with the application of unmanned driving, the requirements for track installation quality are higher. The original track connection structures and installation methods no longer meet functional requirements and have certain technical barriers. Summary of the Invention

[0010] To address the shortcomings of existing technologies, this invention provides a T-shaped arc-shaped press-fit suspension structure and installation method for monorail tracks, which can achieve reliable connection and stable suspension of heavy-duty monorail tracks in mines, further improving the efficiency of auxiliary transportation by monorails in mines.

[0011] This invention is achieved through the following technical solution: a T-shaped arc-shaped press-fit suspension structure for a monorail, comprising a first track and a second track connected together, and a fixed upper suspension assembly. A double-plate bearing seat is fixedly connected to the upper end face of the first track, and a T-shaped single pressure plate is fixedly connected to the upper end face of the second track. The T-shaped single pressure plate has a connecting portion extending into the double-plate bearing seat. The upper suspension assembly includes connecting plates located on both sides of the double-plate bearing seat. A suspension pin passes through the connecting plates, the double-plate bearing seat, and the connecting portion. The connecting portion has an elongated hole adapted to the suspension pin; the elongated hole is an arc-shaped hole. The top surface of the double-plate bearing seat has an arc-shaped bearing surface concentric with the elongated hole. Press-fit plates extend from the upper end of the T-shaped single pressure plate to both sides, and the lower end face of the press-fit plate has an arc-shaped press-fit surface adapted to the arc-shaped bearing surface.

[0012] In this design, the double-plate bearing seat is directly fixed to the first track, and the T-shaped single pressure plate is directly fixed to the second track. When the first and second tracks swing up and down for adjustment, the hanging pin is always in contact with the inner wall of the elongated hole, and the arc-shaped pressing surface is always in contact with and supported on the arc-shaped bearing surface. When the locomotive passes under heavy load, the arc surfaces of the two parts cooperate to bear the weight, avoiding the concentration of all the force at the pin hole position. This reduces the friction at the pin and pin hole position, preventing the pin from breaking and the pin hole from being worn or deformed due to excessive force concentration. This mating surface is an arc mating surface. When the track swings up and down along the lower support point within the specified range, this arc surface can also fit tightly and bear the force evenly.

[0013] As an optimization, it also includes anti-sway horizontal chains that connect to the T-shaped single pressure plate and extend to both sides, and the anti-sway horizontal chains are equipped with turnbuckles. In this solution, the T-shaped single pressure plate is designed with anti-sway horizontal chains, which significantly improves the anti-sway effect of the track.

[0014] As an optimization, the double-plate pressure seat includes two pressure plates welded to the upper end face of the first track, with the connecting part inserted between the two pressure plates. In this solution, the double-plate pressure seat includes two pressure plates, thereby achieving the insertion of the connecting part by welding the two pressure plates separately.

[0015] As an optimization, the inner side of the pressure plate away from the T-shaped single pressure plate is provided with anti-deformation welding protrusions, and the two anti-deformation welding protrusions are welded and fixed. In this solution, the two anti-deformation welding protrusions are welded and fixed to fix the two pressure plates into a whole structure. This serves two purposes: first, to improve the welding strength between the two, and second, to prevent welding deformation or deformation after impact during transportation.

[0016] As an optimization, the hanging pin is located on the side of the mating surface between the first and second tracks closer to the first track. In this design, the hanging pin is located directly above the first track, thus directly transmitting the force to the first track through the double-plate bearing seat.

[0017] As an optimization, the arc length of the contact portion between the arc-shaped bearing surface and the arc-shaped pressing surface is 90-150cm. In this design, the arc length of the contact portion is 90-150cm, which provides excellent support.

[0018] As an optimization, the upper suspension assembly also includes a double-chain suspension base and a suspension rocker arm. The suspension rocker arm is connected to the double-chain suspension base via a suspension chain, and two connecting plates are respectively connected to both sides of the suspension rocker arm. In this solution, the double-chain suspension base is connected to the roadway roof via anchor bolts, and the suspension rocker arm is connected to the double-chain suspension base via a suspension chain, providing a high degree of installation freedom and facilitating on-site installation.

[0019] As an optimization, the front and rear ends of the suspended rocker arm are respectively connected to the double-chain suspension seat via suspension chains, and the double-chain suspension seat is connected to the roadway roof via anchor bolts.

[0020] As an optimization, the connecting plate is hinged to the suspension rocker arm by a bolt. In this solution, the two connecting plates are connected to the suspension rocker arm by a bolt, which enables two-stage floating of the suspension components, avoids rigid suspension connections between tracks, reduces the inertial impact on the tracks caused by locomotive operation, increases the buffer function, and prevents rail torsion.

[0021] An installation method for a T-shaped arc-shaped press-fit suspension structure of a monorail track includes the following steps:

[0022] a. Weld a double-plate pressure seat to the upper end face of the first track, and weld a T-shaped single pressure plate to the upper end face of the second track;

[0023] b. Connect the double-chain hanging base to the roadway roof through anchor bolts. Connect the front and rear ends of the suspension rocker arm to the double-chain hanging base through hanging chains. Install the two connecting plates on both sides of the suspension rocker arm.

[0024] c. Connect the first track and the second track, and leave a gap angle β between the connecting surfaces of the first track and the second track with an upper opening, so that the first track and the second track can swing up and down for adjustment.

[0025] d. Insert the double-plate bearing seat of the first track between the two connecting plates, and insert the connecting part of the T-shaped single pressure plate on the second track into the double-plate bearing seat. The hanging pin passes through the elongated hole of the connecting plate, the double-plate bearing seat and the connecting part. The arc-shaped pressing surface of the lower end of the pressing plate on the T-shaped single pressure plate is supported on the arc-shaped bearing surface of the top surface of the double-plate bearing seat. When the first track and the second track swing up and down, the hanging pin is always in contact with the inner wall of the elongated hole and the arc-shaped pressing surface is always in contact with and supported on the arc-shaped bearing surface.

[0026] e. Connect two anti-sway horizontal chains to the T-shaped single pressure plate and extend them to both sides and connect them to the top plate of the tunnel. Adjust the turnbuckle to tighten the anti-sway horizontal chains.

[0027] The beneficial effects of the present invention are as follows: The T-shaped arc-shaped press-fit suspension structure and installation method of the monorail rail of the present invention reduce welding processes, save time, reduce the number of parts, simplify the process, have a high degree of installation freedom, facilitate on-site installation, effectively prevent excessive left and right swing of the movable rail, realize reliable connection and stable suspension of heavy-duty monorail rails for mining, and further improve the efficiency of auxiliary transportation of monorails in mines.

[0041] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0042] like Figures 1-14 As shown, the present invention provides a T-shaped arc-shaped press-fit suspension structure for a monorail track, comprising a first track 10 and a second track 11 that are joined together. Both the first track 10 and the second track 11 are I-shaped tracks with grooves on their upper and lower end faces.

[0043] A gap angle β is provided between the first track 10 and the second track 11 to allow the first track 10 and the second track 11 to swing up and down around the swing axis, such as... Figure 8 As shown, the gap angle β is a V-shaped angle with an upward opening, which allows the first track and the second track to swing around the swing axis for adjustment. At this time, the size of the gap angle β changes, and the swing axis is located below the gap angle β. The swing axis extends left and right and is perpendicular to the first track 10 and the second track 11, so that the first track and the second track can adjust the angle of their upper and lower docking to adapt to the height changes of the tunnel.

[0044] The lower end of the first track 10 is fixedly connected to a lower pin 15, and the lower end of the second track 11 is fixedly connected to a lower socket 16. The lower socket 16 has a socket groove for inserting the end of the lower pin 15 from bottom to top, so that the first track 10 and the second track 11 will not separate from each other, and will not interfere with the relative up-and-down swing of the first track and the second track.

[0045] The first track 10 and the second track 11 are two sections of track in the docking structure. A double-plate pressure seat 8 is fixed to the upper end surface of the first track 10. The double-plate pressure seat 8 is located at the end of the upper end surface of the first track 10 near the docking surface. A T-shaped single pressure plate 6 is fixed to the upper end surface of the second track 11. The T-shaped single pressure plate 6 is located at the end of the upper end surface of the second track 11 near the docking surface.

[0046] It also includes a fixed upper suspension assembly, which includes connecting plates 9 located on both sides of the double-plate bearing seat 8. The upper suspension assembly also includes a double-chain suspension seat 2 and a suspension rocker arm 4. The double-chain suspension seat 2 is connected to the roadway roof through an anchor bolt 1. The anchor bolt 1 in this application includes both anchor bolts and anchor cables, meaning it can be either an anchor bolt or an anchor cable.

[0047] Therefore, the double-chain suspension seat 2 is close to the roadway roof, ensuring stable suspension, reducing the lateral sway of the anchor bolt, reducing the lateral shear force on the anchor bolt caused by locomotive operation, and preventing fatigue fracture of the anchor bolt under long-term alternating stress.

[0048] The suspension rocker arm 4 is connected to the double-chain hanging base 2 via a suspension chain 12. In this embodiment, the front and rear ends of the suspension rocker arm 4 are respectively connected to the double-chain hanging base 2 via suspension chains 12. The upper end of the suspension chain 12 is connected by an M20 connecting bolt 3 passing through the suspension chain 12 and the double-chain hanging base 2, and the lower end of the suspension chain 12 is connected by an M20 connecting bolt 3 passing through the suspension chain 12 and the suspension rocker arm 4.

[0049] Of course, it can also be done through Figure 10 The structure shown connects the U-shaped ring to the tunnel roof via anchor bolt 1, and the hanging chain 12 is installed on the U-shaped ring.

[0050] Two connecting plates 9 are respectively connected to both sides of the suspension rocker arm 4. In this embodiment, the connecting plates 9 are hinged to the suspension rocker arm 4 by a bolt. Specifically, in this embodiment, an M30 high-strength bolt 5 passes through the middle position of the two connecting plates 9 and the suspension rocker arm 4 to achieve the connection, so that the connecting plates 9 can swing back and forth.

[0051] In this embodiment, the connecting plate 9 can achieve two-stage floating of the hanging component, that is, the upper and lower ends are hinged, avoiding rigid hanging connection between the tracks, reducing the inertial impact of locomotive operation on the tracks, increasing the buffer function, and preventing track torsion. When the connecting plate 9 is connected to the upper suspension rocker arm 4, an M30 high-strength bolt 5 with a stepped shaft structure is used. After the anti-loosening nut of the M30 high-strength bolt 5 is tightened, there is a 2mm gap between the nut and the connecting plate 9, which can ensure that the connecting plate 9 rotates and swings along the hole, but does not cause the connecting plate 9 to displace too much along the bolt axial direction.

[0052] like Figure 1 , 2As shown, the T-shaped single pressure plate 6 is provided with a connecting part 61 extending into the double plate pressure seat 8. The hanging pin 7 passes through the connecting plate 9, the double plate pressure seat 8, and the connecting part 61. The connecting part 64 has an elongated hole 64 adapted to the hanging pin 7. The elongated hole 64 is an arc-shaped hole and is concentric with the swing axis of the first track 10 and the second track 11, so that when the first track and the second track swing relative to the swing axis, the hanging pin 7 in the elongated hole 64 moves in a matching manner within the elongated hole. The hanging pin 7 is located on the side of the mating surface of the first track 10 and the second track 11 closer to the first track 10.

[0053] When the connecting part 61 is inserted into the double plate bearing seat 8, the gap on one side is about 2mm. This margin has the following functions: first, it is for adjustment during installation, making installation convenient; second, when the locomotive is running, at the joint of the rails, the two matching rails have a certain amount of room to move, but will not cause the rails to swing too much to the left and right, will not cause the rails to be twisted in an "S" shape, and will not affect the locomotive's operating efficiency.

[0054] The lower end of the T-shaped single pressure plate 6 is provided with a polygonal welding seat 65, which is welded into the groove on the upper surface of the first track 10.

[0055] The top surface of the double-plate pressure seat 8 is provided with an arc-shaped pressure-bearing surface 82 concentric with the elongated hole 64. A pressing plate 62 extends from the upper end of the T-shaped single pressure plate 6 to both sides. The lower end surface of the pressing plate 62 is provided with an arc-shaped pressing surface 63 adapted to the arc-shaped pressure-bearing surface 82. The arc length of the contact portion between the arc-shaped pressure-bearing surface 82 and the arc-shaped pressing surface 63 is 90-150 cm. The width of the mating surface on one side of the pressing plate 62 is 10 mm, and it is symmetrically and uniformly stressed.

[0056] like Figure 3 As shown, the double-plate pressure seat 8 includes two pressure plates 81 welded to the upper end face of the first track 10. The two pressure plates 81 are arranged in parallel and are both parallel to the T-shaped single pressure plate 6. The connecting part 61 is inserted between the two pressure plates 81.

[0057] The lower end of the pressure plate 81 is welded into the groove on the upper surface of the second track 11. The inner side of the pressure plate 81 away from the T-shaped single pressure plate 6 is provided with anti-deformation welding protrusion 84, and the two anti-deformation welding protrusions 84 are welded and fixed.

[0058] It also includes anti-sway horizontal zipper chains 13 that are connected to the T-shaped single pressure plate 6 and extend to both sides. The anti-sway horizontal zipper chains 13 are equipped with turnbuckles 14 for adjusting the tension of the anti-sway horizontal zipper chains 13. The T-shaped single pressure plate 6 has anti-sway horizontal zipper fixing holes 66 for connecting the anti-sway horizontal zipper chains 13.

[0059] An installation method for a T-shaped arc-shaped press-fit suspension structure of a monorail track includes the following steps:

[0060] a. Weld a double-plate bearing seat 8 to the upper end face of the first track 10, and weld a T-shaped single pressure plate 6 to the upper end face of the second track 11.

[0061] b. Connect the double-chain hanging seat 2 or the U-shaped ring to the roadway roof through the anchor bolt 1. Connect the front and rear ends of the suspension rocker arm 4 to the double-chain hanging seat 2 or the U-shaped ring through the hanging chain 12 respectively. Install the two connecting plates 9 on both sides of the suspension rocker arm 4.

[0062] c. Connect the first track 10 and the second track 11, and leave a gap angle β with an upper opening on the connecting surface of the first track 10 and the second track 11 so that the first track 10 and the second track 11 can swing up and down for adjustment.

[0063] d. Insert the double-plate bearing seat 8 of the first track 10 between the two connecting plates 9. Insert the connecting part 61 of the T-shaped single pressure plate 6 on the second track 11 into the double-plate bearing seat 8. The hanging pin 7 passes through the elongated hole 64 of the connecting plate 9, the double-plate bearing seat 8 and the connecting part 61. The arc-shaped pressing surface 63 of the lower end face of the pressing plate 62 on the T-shaped single pressure plate 6 is supported on the arc-shaped bearing surface 82 on the top surface of the double-plate bearing seat 8. When the first track 10 and the second track 11 swing up and down, the hanging pin 7 is always in contact with the inner wall of the elongated hole 64, and the arc-shaped pressing surface 63 is always in contact with and supported on the arc-shaped bearing surface 82.

[0064] e. Connect two anti-sway horizontal chains 13 to the T-shaped single pressure plate 6 and extend them to both sides and connect them to the top plate of the tunnel. Adjust the turnbuckle to tighten the anti-sway horizontal chains.

[0065] Of course, the above description is not limited to the examples above.
