Description

Technical Field

[0001] This utility model relates to the technical field of monorail auxiliary equipment, specifically to an auxiliary support device. Background Technology

[0002] A monorail locomotive is a widely used rail transport device in coal mines, tunnels, and other underground engineering projects. Powered by an explosion-proof diesel engine or battery, it drives the locomotive along a single track suspended from the top of the tunnel or mine shaft, enabling efficient transport of personnel, materials, or equipment. The entire monorail transport system typically consists of multiple standard-length rail sections connected sequentially. Suspension attachments are installed at the joints between adjacent rails, connecting to a suspension structure fixed to the tunnel ceiling, thus stably suspending the rail in the air.

[0003] In existing track installation processes, the two ends of the previous track are typically first rigidly fixed to the hanging structure on the top plate using hanging accessories to form an initial support foundation. Subsequently, when installing the next track, its first end must be connected to the end of the previous track, and both must be connected to the same hanging structure at the joint to achieve uniform load distribution and structural stability.

[0004] However, because the end of the previous track is completely fixed during initial installation and its spatial position cannot be freely adjusted, precise alignment is difficult to achieve when docking with the next track. To solve this problem, existing technologies typically require loosening or partially disassembling the hanging connection at the end of the previous track, changing it from a fixed state to a movable state, in order to adjust the position of the track end and complete the docking operation.

[0005] This operation not only increases construction procedures and extends work time, but also brings many problems: In the high-altitude working environment, loosening the fixed suspension points may cause the track to suddenly sink or shift laterally, posing a significant safety risk. Therefore, at least one additional worker is often needed below to manually support or assist the track in maintaining its stability, further increasing manpower and coordination difficulties. At the same time, due to the lack of an effective positioning and adjustment mechanism, relying solely on manual adjustment makes it difficult to guarantee the smoothness and straightness of the track joints, easily leading to misalignment, steps, or excessive gaps, seriously affecting the quality of the track connection and the stability and safety of subsequent locomotive operation.

[0006] Therefore, existing technologies still need further development. Utility Model Content

Furthermore, setting the installation part on the anchor rod and the connecting part facing the track section allows the load-bearing structure to effectively transfer the supporting force from the roof to the track area below, achieving a reasonable conversion of the spatial force system. At the same time, this layout provides a clear guide and positioning benchmark for the installation of the connecting structure, which is conducive to achieving precise adjustment and docking of the track section. Furthermore, the connecting structure, as a crucial component bridging the upper and lower sections, not only achieves a flexible connection between the load-bearing structure and the track segment but also provides a technical path for the dynamic adjustment of the track segment's position. This avoids the cumulative installation errors caused by traditional rigid fixing methods, significantly improving the system's adaptability and installation flexibility. In particular, the adjustment section of the connecting structure can precisely control the height, angle, and forward / backward position of the track segment, achieving effective track positioning without loosening or disassembling the original suspension points.

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0022] Please see Figures 1 to 6 According to an embodiment of the present invention, an auxiliary support device is provided, comprising: a load-bearing structure 1 and a connecting structure 2. The load-bearing structure 1 has an mounting part and a connecting part. The mounting part is for mounting on an anchor rod 100, and the connecting part is disposed toward the track section 200. The connecting structure 2 is connected to the connecting part and the track section 200 respectively. The connecting structure 2 has an adjusting part for adjusting the relative position between the track section 200 and the hanging structure disposed on the anchor rod 100.

[0023] As can be seen, the auxiliary support device provided by this utility model includes a load-bearing structure 1 and a connecting structure 2. The load-bearing structure 1 has an mounting part and a connecting part. The mounting part is used to be installed on the anchor rod 100 to achieve overall fixation of the device. The connecting part is connected to the mounting part and is positioned facing the track section 200 for connection with the connecting structure 2. The connecting structure 2 is used to connect the connecting part and the track section 200. The connecting structure 2 has an adjusting part for adjusting the relative position between the track section 200 and the suspension structure installed on the anchor rod 100, thereby achieving precise alignment and docking of the track section 200.

[0024] Therefore, by setting up the load-bearing structure 1, a rapid and reliable connection between the auxiliary support device and the roadway roof is achieved. This fully utilizes existing anchor bolt resources, eliminating the need for additional drilling or reinforcement work, simplifying the installation process, improving construction efficiency, and ensuring the overall load-bearing capacity and stability of the structure. Furthermore, by placing the installation part on the anchor bolt 100 and the connection part facing the track section 200, the load-bearing structure 1 can effectively transfer the supporting force from the roof to the track area below, achieving a reasonable conversion of the spatial force system. Simultaneously, this layout provides clear guidance and positioning benchmarks for the installation of the connecting structure 2, facilitating precise adjustment and docking of the track section 200. Moreover, as a key component connecting the upper and lower sections, the connecting structure 2 not only achieves a flexible connection between the load-bearing structure 1 and the track section 200 but also provides a technical path for the dynamic adjustment of the track section 200's position, avoiding the accumulation of installation errors caused by traditional rigid fixing methods, and significantly improving the system's adaptability and installation flexibility. In particular, the adjustment section of the connecting structure 2 can precisely control the height, angle, and front-to-back position of the track segment 200, achieving effective track positioning. This eliminates the need to loosen or dismantle the original suspension points, fundamentally avoiding safety hazards such as sudden track sinking or lateral shift caused by loosening the fixing structure, and creating favorable conditions for smooth connection with adjacent track segments. Furthermore, through the synergistic effect of the bearing structure 1 and the connecting structure 2, this device can adjust the posture of the end of an installed track segment or the beginning of the next track segment 200 without manual support. This effectively replaces the traditional operation mode where at least one worker is required to provide manual support from below, significantly reducing the number of workers required for high-altitude operations, lowering the difficulty of personnel coordination and labor intensity, improving construction safety and work efficiency, and reducing labor costs. The auxiliary support device of this utility model has a simple structure and is easy to operate, effectively solving the technical problem in the prior art where at least one worker is required to manually support or assist in supporting the previously installed track when connecting and fixing two adjacent tracks.

[0025] The first embodiment of the specific structure of the load-bearing structure 1 provided by this utility model is as follows: like Figure 1 and Figure 5As shown, the supporting structure 1 includes a supporting plate 11 and a connecting plate 12. The supporting plate 11 extends along a first preset direction. The supporting plate 11 has a locking portion for locking with the anchor rod 100. One end of the connecting plate 12 is connected to one end of the supporting plate 11. The connecting plate 12 extends along a second preset direction, and the extension direction of the connecting plate 12 forms a first preset angle with the extension direction of the supporting plate 11. The first preset angle is greater than 0° and less than or equal to 90°. The end of the connecting plate 12 away from the supporting plate 11 is positioned towards the track section 200. The connecting plate 12 has a first hanging engagement portion, which engages with the first hanging portion of the connecting structure 2. The supporting plate 11 forms the mounting portion of the supporting structure 1, and the connecting plate 12 forms the connecting portion of the supporting structure 1.

[0026] With the above-described structure, the bearing plate 11 is equipped with a locking part, which can quickly engage with the anchor bolt 100 on the tunnel roof without the need for additional bolts or welding. This simplifies operation, significantly improves the efficiency of installation and disassembly, facilitates repeated use in multi-point continuous operations, and reduces construction costs. Simultaneously, the bearing plate 11 extends along a first preset direction to connect with the anchor bolt 100 and bear vertical loads. The connecting plate 12 extends along a second preset direction, forming a first preset angle greater than 0° and less than or equal to 90° with the bearing plate 11, thus forming a stable L-shaped or bent structure. This effectively transfers the supporting force from the roof to the lower track area through the corner structure, achieving a reasonable conversion of the spatial force system and improving overall load-bearing stability. Furthermore, the end of the connecting plate 12 furthest from the bearing plate 11 faces the track section 200 and is equipped with a first hanging engagement part, which forms a detachable hanging engagement with the first hanging part of the connecting structure 2. This design not only simplifies the assembly process, but also provides good installation space and freedom of movement for the connecting structure 2, which is conducive to realizing the vertical lifting and attitude adjustment of the track section 200 and improving docking flexibility.

[0027] Preferably, the first preset included angle is 90°. The connection between the bearing plate 11 and the connecting plate 12 adopts a rounded corner transition method.

[0028] Furthermore, such as Figure 1 and Figure 5 As shown, the support plate 11 has an opening groove 111 and a locking groove 112. The opening groove 111 extends along the width direction of the support plate 11, and the locking groove 112 extends along the length direction of the support plate 11. The end of the opening groove 111 is connected to one end of the locking groove 112. The opening groove 111 and the locking groove 112 form a locking part. When the support plate 11 is locked on the anchor rod 100, a limiting member for limiting the support plate 11 is installed on the anchor rod 100, and the support plate 11 is located above the limiting member.

[0029] With the above-described structure, the connection between the load-bearing structure and the anchor rod can be completed by sliding the anchor rod 100 laterally into the opening slot 111 and then sliding it along the locking slot 112 to the limiting position. No bolts, nuts, or special tools are required, making the operation simple and quick. This is particularly suitable for complex working environments such as high altitudes and confined spaces, significantly improving installation and disassembly efficiency. Simultaneously, the "slide-in-lock" connection mechanism formed by the opening slot 111 and the locking slot 112 ensures a stable mechanical fit between the load-bearing plate 11 and the anchor rod 100 after installation. The load is directly transferred to the anchor rod body through the slot wall, resulting in a clear force path, high connection rigidity, and reliable resistance to dynamic loads generated during track adjustment. Furthermore, the locking slot 112 provides axial restraint for the anchor rod 100, preventing the load-bearing plate from slipping off the anchor rod under vertical loads. Simultaneously, in conjunction with the limiting component on the anchor rod, the load-bearing plate 11 is positioned above the limiting component, forming a double anti-detachment structure. This effectively prevents the device from loosening or falling due to vibration or impact, significantly improving safety.

[0030] Among them, such as Figure 2 The direction indicated by arrow A is the length direction of the support plate 11, and the direction indicated by arrow B is the width direction of the support plate 11.

[0031] Optionally, the opening groove 111 and the locking groove 112 are interconnected and combined to form an integral L-shaped sliding locking groove structure. The opening groove 111 extends along the width direction of the supporting plate 11, serving as the initial guide channel for the anchor rod 100; the locking groove 112 extends along the length direction of the supporting plate 11, guiding the axial sliding of the anchor rod 100 and achieving final positioning. The two meet on the supporting plate 11 to form a right-angled or near-right-angled L-shaped groove structure, collectively constituting a locking part for engaging with the anchor rod 100.

[0032] Furthermore, such as Figure 1 As shown, the limiting component installed on the anchor bolt 100 for limiting the bearing plate 11 can adopt various structural forms, which can be flexibly adapted according to the actual suspension system configuration. For example, in the suspension structure of a heavy-duty monorail, two anchor bolts 100 are inclinedly set on the tunnel roof. The suspension structure includes: two shackles 301, which are respectively installed on the free ends of the corresponding anchor bolts 100; each shackle 301 is connected to the rocker arm 303 through the first chain 302; the rocker arm 303 is then connected to one of the first welding attachments 306 and the second welding attachments 307 on the two adjacent track sections 200 through the figure-eight ring 304; finally, through the connection between the first welding attachment 306 and the second welding attachment 307, the two adjacent track sections 200 are reliably connected to the suspension structure and completed in docking.

[0033] In this type of suspension structure, the shackle 301 is located at the end of the anchor rod 100, and its structure protrudes from the axial direction of the anchor rod, effectively preventing the bearing plate 11 from slipping off along the anchor rod. When the bearing plate 11 slides into and is positioned in the locking groove 112 through its locking part, it is blocked above by the shackle 301, thereby forming a reliable axial limit and preventing the auxiliary support device from accidentally falling off during use.

[0034] Therefore, the shackle 301 in the hanging structure has both connection and limiting functions. It can be used as a limiting component to limit the bearing plate 11 without the need for additional special limiting parts. It makes full use of existing hanging components to achieve structural integration and functional reuse, and has the advantages of compact structure, convenient installation, safety and reliability.

[0035] For example, such as Figure 2 As shown, in the suspension structure of the monorail light rail, two anchor bolts 100 are vertically installed on the tunnel roof. The suspension structure includes a suspension seat 401, which is fitted onto the two anchor bolts 100 and secured to them by two first bolts, ensuring that the free ends of both anchor bolts 100 are located below the suspension seat 401. The suspension structure also includes a second chain 402, one end of which is connected to the suspension seat 401 and positioned between the two anchor bolts 100; the other end of the second chain 402 is connected via a U-shaped connector to a third welding attachment 403 and a fourth welding attachment 404 installed on two adjacent track sections 200. Ultimately, through the connection between the third welding attachment 403 and the fourth welding attachment 404, the adjacent track sections 200 are reliably connected to the suspension structure and simultaneously docked.

[0036] In this type of suspension structure, for anchor rods 100 requiring auxiliary support devices, an additional second bolt 6 is provided at their free end. During installation, the bearing plate 11 of the bearing structure 1 is first slid into the anchor rod 100 through its locking part, and then slides along the locking groove 112 to a predetermined position, so that the bearing plate 11 is located between the first bolt and the second bolt 6. Subsequently, the second bolt 6 is tightened to press or limit the bearing plate 11, thereby preventing it from coming out along the axial direction of the anchor rod.

[0037] Therefore, in this embodiment, the second bolt 6 serves as a dedicated limiting component, cooperating with the bearing plate 11 to form a reliable axial constraint, effectively preventing the auxiliary support device from accidentally falling off due to vibration or load during use. This limiting method has a simple structure, is easy to operate, and makes full use of the existing thread structure of the anchor bolt, requiring no additional processing or parts, thus possessing good feasibility and safety.

[0038] Furthermore, a second connecting hole 121 is provided on the connecting plate 12 to form a first mounting mating part.

[0039] Furthermore, the load-bearing structure 1 also includes a reinforcing plate 13, which is disposed on one side of the load-bearing plate 11 and connected to both the load-bearing plate 11 and the connecting plate 12. With this structural arrangement, the load-bearing plate 11 and the connecting plate 12 form a first preset angle at their connection point. This angled area is prone to stress concentration when subjected to track adjustment loads or external impacts. By reinforcing this angled area with the reinforcing plate 13, local stress is effectively dispersed, preventing structural deformation or fatigue cracking due to long-term stress, and significantly improving the overall load-bearing capacity and structural reliability of the device. Simultaneously, the reinforcing plate 13, as a supporting rib connecting the load-bearing plate 11 and the connecting plate 12, forms a structure similar to a "triangular reinforcing rib," improving the bending and torsional resistance of the load-bearing structure 1 under vertical loads and lateral disturbances, ensuring the device remains stable and does not shift during track docking, and guaranteeing operational safety.

[0040] The second embodiment of the specific structure of the load-bearing structure 1 provided by this utility model is as follows: like Figure 2 and Figure 6 As shown, the bearing structure 1 includes a bearing plate 11 and a connecting plate 12. The bearing plate 11 extends along a first preset direction. The bearing plate 11 is provided with a first connecting hole 113, through which the bearing plate 11 is installed on the anchor rod 100. One end of the connecting plate 12 is connected to one end of the bearing plate 11. The connecting plate 12 extends along a second preset direction, and the extension direction of the connecting plate 12 and the extension direction of the bearing plate 11 form a second preset angle, which is greater than 0° and less than or equal to 90°. The end of the connecting plate 12 away from the bearing plate 11 is positioned towards the track section 200. The connecting plate 12 is provided with a first hanging engagement part, which engages with the first hanging part of the connecting structure 2. When the bearing plate 11 is installed on the anchor rod 100, a limiting member for limiting the bearing plate 11 is installed on the anchor rod 100, and the bearing plate 11 is located above the limiting member. The support plate 11 forms the mounting part of the support structure 1, and the connecting plate 12 forms the connecting part of the support structure 1.

[0041] Preferably, the second preset included angle is 90°, and the connection between the bearing plate 11 and the connecting plate 12 adopts a rounded corner transition method.

[0042] Furthermore, the limiting component on the anchor rod 100 used to limit the bearing plate 11 can adopt various structural forms, which can be flexibly adapted according to the type of suspension system in actual application, and have good versatility and engineering adaptability.

[0043] For example, such as Figure 1As shown, in the suspension structure of the heavy-duty monorail, two anchor bolts 100 are inclinedly installed on the tunnel roof. The suspension structure includes two shackles 301, which are respectively installed on the free ends of the corresponding anchor bolts 100; each shackle 301 is connected to a rocker arm 303 via a first chain 302; the rocker arm 303 is then connected to one of the first welded attachments 306 and the second welded attachments 307 on two adjacent track sections 200 via a figure-eight ring 304; finally, through the connection between the first welded attachment 306 and the second welded attachment 307, the adjacent track sections 200 are reliably connected to the suspension structure and docked.

[0044] In this type of suspension structure, the shackle 301 is installed at the free end of the anchor rod 100. Its structural dimensions are larger than the diameter of the anchor rod, and it protrudes spatially from the anchor rod axis, effectively preventing the bearing plate 11 from slipping off along the anchor rod axially. Therefore, during assembly, for anchor rods 100 requiring auxiliary support devices, the bearing structure 1 can first be fitted onto the anchor rod 100 through the first connecting hole 113 on the bearing plate 11, and then slid along the anchor rod to a predetermined position; subsequently, the corresponding shackle 301 is installed at the free end of the anchor rod. At this time, the bearing plate 11 is located below and limited by the shackle 301, forming a reliable axial constraint.

[0045] Therefore, in this embodiment, the shackle 301 not only serves as the connection between the chain and the anchor rod in the suspension system, but also acts as a limiting component for the bearing plate 11, achieving multi-functional integration. This design eliminates the need for additional dedicated limiting parts, fully utilizing existing suspension components to achieve structural limiting, and has significant advantages such as compact structure, convenient assembly, safety and reliability, and low cost.

[0046] For example, such as Figure 2 As shown, in the suspension structure of the monorail light rail, two anchor bolts 100 are vertically installed on the tunnel roof. The suspension structure includes a suspension seat 401, which is fitted onto the two anchor bolts 100 and secured to them by two first bolts, ensuring that the free ends of both anchor bolts 100 are located below the suspension seat 401. The suspension structure also includes a second chain 402, one end of which is connected to the suspension seat 401 and positioned between the two anchor bolts 100; the other end of the second chain 402 is connected via a U-shaped connector to a third welding attachment 403 and a fourth welding attachment 404 installed on adjacent track sections 200. Ultimately, through the connection between the third welding attachment 403 and the fourth welding attachment 404, the adjacent track sections 200 are reliably connected to the suspension structure and simultaneously docked.

[0047] In this type of suspension structure, for anchor rods 100 that require auxiliary support devices, an additional second bolt 6 is provided at their free end. During installation, the bearing plate 11 of the bearing structure 1 is first inserted through the first connecting hole 113 on it from the free end of the anchor rod 100 and slid along the anchor rod axially to the predetermined installation position; then, the second bolt 6 is screwed into the free end of the anchor rod 100 and gradually tightened, so that the bearing plate 11 is clamped between the first bolt and the second bolt 6, forming an axial limit.

[0048] In this way, the second bolt 6, as a special limiting component, works with the bearing plate 11 to form a reliable mechanical constraint structure, effectively preventing the auxiliary support device from axially slipping due to vibration, impact or external force during operation, thus ensuring the safety of high-altitude operations.

[0049] Optionally, the load-bearing structure of this embodiment is applicable to the suspension structure of the monorail light rail as shown in the figure.

[0050] Furthermore, a second connecting hole 121 is provided on the connecting plate 12 to form a first mounting mating part.

[0051] Furthermore, the load-bearing structure 1 also includes a reinforcing plate 13, which is disposed on one side of the load-bearing plate 11 and connected to both the load-bearing plate 11 and the connecting plate 12. With this structural arrangement, the load-bearing plate 11 and the connecting plate 12 form a second preset angle at their connection point. This angled area is prone to stress concentration when subjected to track adjustment loads or external impacts. By reinforcing this angled area with the reinforcing plate 13, local stress is effectively dispersed, preventing structural deformation or fatigue cracking due to long-term stress, and significantly improving the overall load-bearing capacity and structural reliability of the device. Simultaneously, the reinforcing plate 13, as a supporting rib connecting the load-bearing plate 11 and the connecting plate 12, forms a structure similar to a "triangular reinforcing rib," improving the bending and torsional resistance of the load-bearing structure 1 under vertical loads and lateral disturbances, ensuring the device remains stable and does not shift during track docking, and guaranteeing operational safety.

[0052] The first embodiment of the specific structure of the connection structure 2 provided by this utility model is as follows: like Figure 3 and Figure 4As shown, the connecting structure 2 includes: a scissor lift assembly 21, a first mounting member 22, a second mounting member 23, and a locking assembly 24. The scissor lift assembly 21 is vertically extendable. The first mounting member 22 is located at the top of the scissor lift assembly 21 and is used to hang on the supporting structure 1. The second mounting member 23 is located at the bottom of the scissor lift assembly 21 and is used to hang on the track section 200. The locking assembly 24 is used to lock and unlock the scissor lift assembly 21. The locking assembly 24 has a locked state and an unlocked state. When the scissor lift assembly 21 extends or retracts to the target height, the locking assembly 24 connects to the scissor lift assembly 21, so that the locking assembly 24 is in the locked state to fix the height of the scissor lift assembly 21. When the height of the scissor lift assembly 21 needs to be adjusted, the locking assembly 24 separates from the scissor lift assembly 21, so that the locking assembly 24 is in the unlocked state to allow the scissor lift assembly 21 to extend and retract freely. The first mounting member 22 forms the first mounting part of the connecting structure 2. The scissor lift assembly 21 forms the adjustment section of the connection structure 2.

[0053] With the above-described structure, the scissor lift assembly 21 is vertically extendable, forming the adjustment section of the connecting structure 2. This allows for continuous lifting and lowering of the track segment 200 within a large travel range, facilitating precise adjustment and docking of the track segment 200. This keeps the track segment 200 in the target position, facilitating subsequent connection with the suspension structure. It also allows for the adjustment of the posture of the end of an installed track segment or the beginning of the next track segment 200 without manual support. This effectively replaces the traditional operation mode where at least one worker is required to provide manual support from below, significantly reducing the number of workers required for high-altitude work, lowering coordination difficulties and labor intensity, improving construction safety and work efficiency, and reducing labor costs. Simultaneously, the first mounting component 22 is located at the top of the scissor lift assembly 21 and is used to engage with the first mounting mating part of the supporting structure 1; the second mounting component 23 is located at the bottom of the scissor lift assembly and is used to hang on the track segment 200. The two components form a dual-attached connection, enabling a boltless, detachable, and quick connection between the connecting structure 2 and the supporting structure 1 and the track. Assembly and disassembly can be completed without tools, significantly improving the efficiency of high-altitude operations and facilitating the repeated use of the device. Furthermore, the locking component 24 is used to lock and unlock the scissor lift assembly 21, with clearly defined locked and unlocked states. When the scissor lift assembly extends or retracts to the target height, the locking component 24 connects to the scissor lift assembly 21 and enters the locked state, effectively fixing its current height and preventing accidental sinking or displacement during track docking. When height adjustment is required, the locking component 24 disengages, entering the unlocked state, allowing the scissor lift assembly 21 to extend and retract freely. This mechanism achieves flexible switching between "adjustment-locking" functions, balancing operational flexibility and safety.

[0054] Furthermore, the connecting plate 12 of the load-bearing structure 1 is provided with a first mounting engagement part that is compatible with the first mounting member 22, and the track section 200 is provided with a second mounting engagement part that is compatible with the second mounting member 23. The first mounting engagement part is mounted and engaged with the first mounting member 22, and the second mounting engagement part is mounted and engaged with the second mounting member 23.

[0055] Optionally, the second connecting hole 121 of the connecting plate 12 forms a first hanging mating part, the first hanging member 22 is a second hook, and the second hanging member 23 is a third hook.

[0056] Furthermore, a support frame 500 is fitted onto the track section 200, and a hanging rod 501 is provided above the track section 200 on the support frame 500. The hanging rod 501 extends in the lateral direction of the track section 200 and forms a second mounting mating part. Alternatively, a third connecting hole is provided on the track section 200, which also forms a second mounting mating part.

[0057] Furthermore, the support frame 500 includes a first support plate 502, a second support plate 503, and a base plate 504. Both the first support plate 502 and the second support plate 503 extend vertically. The first support plate 502 and the second support plate 503 are located on both sides of the web of the track section 200 (i.e., the first support plate 502 and the second support plate 503 are spaced apart along the transverse direction of the track section 200), and the first support plate 502 and the second support plate 503 are arranged opposite to each other. The base plate 504 is located at the bottom of the track section 200, and the base plate 504 is connected to the first support plate 502 and the second support plate 503 respectively. The hanging rod 501 is connected to the top of the first support plate 502 and the top of the second support plate 503 respectively. The hanging rod 501 is located above the track section 200, and the hanging rod 501 is located between the first support plate 502 and the second support plate 503.

[0058] It should be noted that after the connection of two adjacent track sections is completed, the support frame 500, hanging rod 501 and connecting structure 2 will be removed.

[0059] Furthermore, such as Figure 3 and Figure 4As shown, the scissor fork assembly 21 includes: a first scissor fork bar 211, a second scissor fork bar 212, a third scissor fork bar 214, a fourth scissor fork bar 215, a first bracket 217, and a second bracket 218. The first scissor fork bar 211 and the second scissor fork bar 212 are hinged together by a first pin 213; the third scissor fork bar 214 and the fourth scissor fork bar 215 are hinged together by a second pin 216; the first bracket 217 is located above the end of the first scissor fork bar 211 away from the second scissor fork bar 212 and the end of the third scissor fork bar 214 away from the fourth scissor fork bar 215; the first scissor fork bar 211 is located above the end of the second scissor fork bar 212 away from the second scissor fork bar 213 .... One end of the fork 212 and the end of the third scissor bar 214 away from the fourth scissor bar 215 are both hinged to the first bracket 217, and the first hanging member 22 is located on the top of the first bracket 217; the second bracket 218 is located below the end of the second scissor bar 212 away from the first scissor bar 211 and the end of the fourth scissor bar 215 away from the third scissor bar 214; the end of the second scissor bar 212 away from the first scissor bar 211 and the end of the fourth scissor bar 215 away from the third scissor bar 214 are both hinged to the second bracket 218, and the second hanging member 23 is located on the bottom of the second bracket 218.

[0060] With the above-described structure, the first scissor lift 211 and the second scissor lift 212 are hinged together by the first pin 213, and the third scissor lift 214 and the fourth scissor lift 215 are hinged together by the second pin 216, forming two sets of cross-hinged linkage mechanisms. This symmetrical arrangement ensures that the load is evenly distributed on both sides, effectively avoiding structural distortion or local deformation caused by eccentric forces, significantly improving the overall rigidity and vertical load-bearing capacity of the scissor lift assembly, and stably supporting the dynamic load of the track section during adjustment. Furthermore, the scissor lifts are hinged together by pins, so when they extend or retract under external force, each member moves synchronously along a predetermined trajectory, ensuring smooth and uninterrupted lifting. This mechanism has good guiding and self-stabilizing characteristics, ensuring that the track section 200 maintains a horizontal posture during height adjustment, avoiding tilting or swaying, and improving docking accuracy. Meanwhile, the first bracket 217 and the second bracket 218 serve as connecting bases for the upper and lower ends of the scissor lift assembly 21. They not only enhance the structural strength of the hinge area but also effectively disperse the stress concentration at the pin connection, preventing wear of the hole wall or cracking of the rod due to long-term repeated expansion and contraction, thus extending the service life of the device.

[0061] Furthermore, the first pin 213 and the second pin 216 are symmetrically arranged.

[0062] Furthermore, the end of the first scissor bar 211 away from the second scissor bar 212 and the end of the third scissor bar 214 away from the fourth scissor bar 215 are respectively hinged to the first bracket 217 via the third pin 219. The end of the first scissor bar 211 away from the second scissor bar 212 and the end of the third scissor bar 214 away from the fourth scissor bar 215 are spaced apart on the first bracket 217. The end of the second scissor bar 212 away from the first scissor bar 211 and the end of the fourth scissor bar 215 away from the third scissor bar 214 are respectively hinged to the second bracket 218 via the fourth pin 210. The end of the second scissor bar 212 away from the first scissor bar 211 and the end of the fourth scissor bar 215 away from the third scissor bar 214 are spaced apart on the second bracket 218.

[0063] Specifically, a first threaded hole is provided on the first pin 213, and the extension direction of the first threaded hole is perpendicular to the axis of the first pin 213; a second threaded hole is provided on the second pin 216, and the extension direction of the second threaded hole is perpendicular to the axis of the second pin 216; the locking assembly 24 includes a locking rod 241, which has a first threaded section and a second threaded section that are respectively adapted to the first threaded hole and the second threaded hole; when the scissor fork assembly 21 extends or retracts to the target height, the locking rod 241 passes through the first threaded hole and the second threaded hole in sequence, and the locking rod 241 is threadedly engaged with the first threaded hole and the second threaded hole respectively.

[0064] With the above-described structure, when the scissor lift assembly 21 extends or retracts to the target height, the locking rod 241 is sequentially screwed into the first threaded hole on the first pin 213 and the second threaded hole on the second pin 216, achieving a tight connection through threaded engagement. This method transforms the originally movable scissor lift hinge point into a rigid connection, effectively preventing the scissor lift assembly from spontaneously retracting or extending under load, avoiding accidental subsidence or displacement of the track section, and significantly improving safety during high-altitude operations and locomotive operation. Simultaneously, the locking rod 241 has a first threaded section and a second threaded section at both ends that match the threaded holes, providing preload through threaded engagement to form a stable mechanical connection. The threaded connection itself has excellent self-locking characteristics, enabling it to maintain a locked state for extended periods in the frequently vibrating mine environment, preventing loosening. In addition, the locking rod 241 passes through and connects the first pin 213 and the second pin 216 at the same time, which is equivalent to locking the hinge points on the left and right sides of the scissor lift assembly simultaneously. This effectively prevents structural eccentricity, torsion or local stress concentration caused by locking on one side, ensuring that the scissor lift assembly 21 is subjected to balanced force as a whole, and improving the structural stiffness and stability after adjustment.

[0065] Furthermore, one end of the locking rod 241 is provided with a through hole, and the through hole has an internal thread; the locking assembly 24 has a grip 242, which has an external thread adapted to the internal thread, so that the grip 242 is connected to the locking rod 241 through the threaded engagement of the internal thread and the external thread of the grip 242. With this structural design, by providing a detachable grip 242, the operator can quickly connect it to the locking rod 241 to form an extended operating handle, which facilitates the application of force and precise alignment, significantly reduces the difficulty of installation and disassembly, and improves work efficiency.

[0066] The second embodiment of the specific structure of the connection structure 2 provided by this utility model is as follows: like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the connecting structure 2 includes: a housing 25, a zipper 27, a drive sprocket, and a chain link 291. The housing 25 has a first hook 26 protruding from it for connection to the supporting structure 1. A rotatable shaft 28 is located inside the housing 25. A portion of the zipper 27 is wound around the shaft 28, and this portion is located within the housing 25. The free end of the zipper 27 is connected to a first hook 29 for hanging on the track section 200. The drive sprocket is rotatably mounted on one side of the housing 25 and connected to the shaft 28. The chain link 291 is mounted on the drive sprocket to drive its rotation, thereby adjusting the length of the zipper 27. The first hook 26 forms the first hanging portion of the connecting structure 2. The zipper 27, shaft 28, drive sprocket, and chain link 291 form the adjusting portion of the connecting structure 2.

[0067] With the above-described structure, the zipper 27 is partially wound around the rotating shaft 28 inside the housing 25, and its free end is connected to the first hook 29 for hanging on the track section 200. By driving the rotating shaft to rotate via a drive sprocket, the length of the zipper can be controlled, thereby achieving continuous, smooth, and stepless vertical lifting and lowering adjustment of the track section with high precision, meeting the precise alignment requirements under different working conditions. Simultaneously, the drive sprocket is connected to the rotating shaft 28 and drives its rotation via the chain link 291, forming a transmission mechanism similar to a "hand-operated hoist." This structure has a certain mechanical transmission ratio, enabling the lifting or lowering of a large load with a relatively small input force, significantly reducing the operator's effort, and is particularly suitable for adjustment operations when bearing heavy track sections.

[0068] Furthermore, the connecting structure 2 also includes a protective disc 292, which is disposed on one side of the housing 25. A receiving cavity is formed between the protective disc 292 and the housing 25, and the drive sprocket is located in the receiving cavity. The protective disc 292 prevents the chain link 291 from disengaging from the drive sprocket and has a limiting function.

[0069] Optionally, in this embodiment, the connection structure 2 is a hand-operated hoist.

[0070] Furthermore, the connecting plate 12 of the bearing structure 1 is provided with a first mounting engagement part that engages with the first hook 26, and the track section 200 is provided with a second mounting engagement part that matches the first pull hook 29. The first mounting engagement part engages with the first hook 26, and the second mounting engagement part engages with the first pull hook 29. The second connecting hole 121 of the connecting plate 12 forms the first mounting engagement part.

[0071] Furthermore, a support frame 500 is fitted onto the track section 200, and a hanging rod 501 is provided above the track section 200 on the support frame 500. The hanging rod 501 extends in the lateral direction of the track section 200 and forms a second mounting mating part. Alternatively, a third connecting hole is provided on the track section 200, which also forms a second mounting mating part.

[0072] Furthermore, the support frame 500 includes a first support plate 502, a second support plate 503, and a base plate 504. Both the first support plate 502 and the second support plate 503 extend vertically. The first support plate 502 and the second support plate 503 are located on both sides of the web of the track section 200 (i.e., the first support plate 502 and the second support plate 503 are spaced apart along the transverse direction of the track section 200), and the first support plate 502 and the second support plate 503 are arranged opposite to each other. The base plate 504 is located at the bottom of the track section 200, and the base plate 504 is connected to the first support plate 502 and the second support plate 503 respectively. The hanging rod 501 is connected to the top of the first support plate 502 and the top of the second support plate 503 respectively. The hanging rod 501 is located above the track section 200, and the hanging rod 501 is located between the first support plate 502 and the second support plate 503.

[0073] It should be noted that after the connection of two adjacent track sections is completed, the support frame 500, hanging rod 501 and connecting structure 2 will be removed.
