Description

Technical Field

[0001] The present invention relates to the technical field of rail transit vehicle moving equipment, and in particular to a straddle-type monorail vehicle moving platform and a moving method thereof. Background Art

[0002] Straddle-type monorail transportation is increasingly being used in urban rail transit construction due to its significant advantages such as small footprint, good landscape, and adaptability to complex terrain. However, in the current manufacturing and maintenance of straddle-type monorail vehicles at home and abroad, there is a lack of dedicated vehicle moving equipment, and the only way to move the vehicle is to use the traditional double-track vehicle moving platform. The traditional double-track vehicle moving platform is mainly composed of a double-track carrier, which is equipped with two longitudinal tracks and a transverse walking mechanism that drives it along the transverse track. This type of moving platform is only designed for conventional double-track vehicles. Its structure and function cannot meet the moving needs of straddle-type monorail vehicles, and it has the following obvious defects: (1) Poor track compatibility: The traditional double-track vehicle moving platform structure design is only suitable for double-track track types and is not compatible with the single-rail beam support structure of straddle-type monorail vehicles. As a result, multiple sets of moving equipment are required in rail transit operation and maintenance, which greatly increases equipment purchase costs and site occupancy rate. (2) Insufficient traction and positioning: The existing vehicle moving platform is not equipped with a special traction and positioning mechanism for monorail vehicles, making it difficult to achieve accurate traction and stable parking of monorail vehicles, resulting in low vehicle moving efficiency and safety. (3) Low stability during vehicle movement: In actual operation, placing a straddle-type monorail vehicle on a carrier and then loading it onto the longitudinal track of a double-track carrier will create a higher center of gravity. When the double-track carrier moves laterally driven by the lateral walking mechanism, the carrier is very likely to experience unstable conditions such as shaking and imbalance, posing a risk of rollover. To ensure safety, additional strapping is required to securely tie the vehicle, carrier, and double-track carrier, which increases the operational steps. After the vehicle arrives at the target location, the strapping needs to be removed. The entire vehicle moving process is cumbersome and complex, requiring high physical strength and labor intensity from the staff. In addition, there are multiple safety hazards such as vehicle sliding, vehicle transfer platform tipping over, and personnel collisions, which seriously restrict the efficient and safe development of straddle-type monorail vehicle manufacturing and maintenance work. Therefore, developing a vehicle moving device that is compatible with the needs of straddle-type monorail vehicle moving platforms and has high safety and reliability has become a technical problem that needs to be solved urgently. Summary of the Invention

[0003] The purpose of the present invention is to provide a straddle-type monorail vehicle moving platform, which aims to solve the problems of complex operation, high labor intensity, long time consumption and low safety of existing straddle-type monorail vehicle moving, improve the moving efficiency and safety of straddle-type monorail vehicles, and at the same time achieve compatible moving of conventional double-track vehicles.

[0004] The camshaft is a track mounted on the side of the vehicle frame, and the track is mounted on a link cam of the vehicle frame. The camshaft is a track mounted on the side of the vehicle frame, and the track is mounted on a link cam of the vehicle frame. The camshaft is a track mounted on the side of the vehicle frame, and the track is mounted on the link cam of the vehicle frame.

[0005] Furthermore, the traction mechanism adopts a winch, and can pull the straddle-type monorail vehicle to move along the monorail beam through a steel wire rope.

[0006] Furthermore, a stopper is provided on the front end of the monorail beam along the traction direction of the straddle-type monorail vehicle, and at least one blocker is installed on the stopper.

[0007] Furthermore, the longitudinal walking mechanism has and is symmetrically distributed on two longitudinal tracks.

[0008] Furthermore, a brake mechanism is provided on the wheel seat of the longitudinal walking mechanism; the brake mechanism includes two symmetrically arranged clamping arms; two turbines are respectively provided on the upper part of the two clamping arms; the two turbines are rotatably mounted on the wheel seat; a worm shaft is rotatably provided on the wheel seat; the worm shaft has two worm segments (B, B) with opposite rotation directions and are respectively engaged with the two turbines; the worm shaft is driven to move by a locking motor provided on the wheel seat; two clamping hooks are respectively provided at the lower ends of the two clamping arms and are used to symmetrically clamp or loosen the two sides of the rail waist of the longitudinal track.

[0009] Furthermore, a U-shaped groove with an opening facing downward is provided in the middle of the monorail carrier, and a counterweight block is provided in the U-shaped groove; Furthermore, the middle portion of the counterweight block is rotatably connected to the top wall of the U-shaped groove through a swing arm.

[0010] The present invention also discloses a vehicle moving method, which adopts the straddle-type monorail vehicle moving platform described in any one of the above technical solutions, and is characterized by comprising the following steps: S10 preparation stage: parking the double-track carrier at the vehicle pickup position; starting the longitudinal travel mechanism and driving the single-track carrier to move along the longitudinal track so that the single-track beam is aligned with the straddle-type monorail vehicle to be picked up; S20: the vehicle picking-up stage: the traction mechanism releases the wire rope and connects to the straddle-type monorail vehicle; the traction mechanism is activated to pull the straddle-type monorail vehicle along the monorail beam; when the straddle-type monorail vehicle reaches a predetermined position, it is stopped by the blocker, and the traction mechanism brakes and fixes the straddle-type monorail vehicle; S30 vehicle moving stage: start the longitudinal traveling mechanism to move the monorail carrier and the straddle-type monorail vehicle to the middle position of the longitudinal track; then start the transverse traveling mechanism to translate the double-track carrier along the transverse track to the target position, so that the longitudinal track is aligned with the target track; S40: Vehicle releasing stage: starting the longitudinal traveling mechanism to drive the monorail carrier and the straddle-type monorail vehicle to move along the longitudinal track and onto the target track, thus completing the vehicle moving.

[0011] Furthermore, during the vehicle moving stage, the brake mechanism of the longitudinal traveling mechanism is released when the straddle-type monorail vehicle moves; when the straddle-type monorail vehicle stops, the clamping hooks of its two clamping arms clamp the rail waist of the longitudinal rail to fix the monorail carrier.

[0012] Furthermore, during the preparation stage and the vehicle moving stage, the hook portions at the lower ends of the two safety hooks always extend into both sides of the rail waist of the longitudinal track to prevent the monorail carrier from derailing.

[0013] First, the present invention innovatively adds a monorail carrier, monorail beams, and a supporting traction mechanism to the traditional double-track carrier, forming a unique composite structure. The monorail carrier can move independently on the longitudinal track of the double-track carrier and can work in conjunction with the double-track carrier, allowing the vehicle moving platform to handle both conventional double-track vehicles and the structural characteristics of straddle-type monorail vehicles. This breaks through the limitation of the traditional vehicle moving platform's single track type, achieving dual-purpose use. Compared with existing technologies, this significantly reduces equipment acquisition costs and site occupancy in rail transit operations and maintenance. Second, the present invention provides opposing safety hooks on the wheel seats of the longitudinal travel mechanism. These hooks extend into both sides of the longitudinal rail waist, forming a mechanical limit structure. Compared with the existing guidance method that relies solely on wheel-rail contact, this provides dual anti-derailment protection. At the same time, the brake mechanism adopts the self-locking principle of the worm gear. The clamping hook of the clamping arm driven by the locking motor clamps the rail waist, further securing the monorail carrier. This effectively overcomes the problem of the monorail carrier's high center of gravity, which makes it prone to shaking and imbalance during lateral movement, and significantly improves the safety of equipment operation. Third, the traction mechanism of the present invention uses a winch to pull the vehicle via a steel wire rope, and works in conjunction with a blocking device. The winch brake cooperates with the blocker to achieve combined control of traction, positioning, and braking. The winch has high traction force and strong controllability. Compared with traditional human or maintenance tractor traction methods, it significantly improves the reliability and safety of the vehicle moving process. At the same time, the block at the front end of the monorail beam and the blocker form a double limit to prevent the vehicle from running off the track, further strengthening safety protection. This technical solution solves the problems of inaccurate positioning and low safety during existing vehicle moving processes. Fourth, the present invention utilizes a monorail carriage and its integrated longitudinal travel mechanism, monorail beams, and traction mechanism as independent modules. These modules can be independently separated from the dual-track carriage or work in conjunction with each other. Furthermore, the monorail carriage can be flexibly adjusted to the specifications of the straddle-type monorail vehicle without affecting the dual-track vehicle's maneuvering function. Furthermore, the maneuvering process is automated through winch traction, a reduction motor-driven travel mechanism, and an electrically controlled brake mechanism. This automated traction, travel, and brake control work in concert, streamlining the maneuvering process, reducing steps and time, minimizing manual intervention, and lowering worker workload. This improves work efficiency, while lowering labor costs and safety risks. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The present invention will be further described below with reference to the accompanying drawings and examples: Example 1: See Figure 1-9 A straddle-type monorail vehicle moving platform comprises a double-track carrier 1, on which two longitudinal rails 1-1 and a transverse running mechanism 1-2 for driving the double-track carrier 1 to move along the transverse rails 1-3 are fixedly provided. In this embodiment, specifically, there are three transverse rails 1-3 fixedly arranged on the foundation in parallel and at intervals. There are six transverse running mechanisms 1-2 arranged at the bottom of the double-track carrier 1 and distributed at different positions, evenly distributed on the three transverse rails 1-3. This part of the structure constitutes the existing double-track vehicle moving platform, which is used for conventional double-track vehicle moving. Since it belongs to the existing technology, it will not be described in detail. This embodiment adds the following structural design (distinguishing features) on the basis of the existing technology, so that it can also be used for straddle-type monorail vehicle moving, as follows: See Figure 1-4The monorail carriage 2 also includes a monorail frame 2; a monorail beam 2-1 (in this embodiment, integrally formed) is fixedly mounted in the middle of the monorail frame 2; at least four longitudinal running mechanisms 3 are provided at the bottom of the monorail frame 2, each configured to engage with two longitudinal rails 1-1; a traction mechanism 4 is provided on the monorail frame 2 for pulling a straddle-type monorail vehicle N along the monorail beam 2-1, and a blocker 5 is provided for stopping the straddle-type monorail vehicle N. Specifically, the blocker 5 can be a hydraulic railway track blocker, such as the XCD series model from Shandong Jiufang Transportation Engineering Co., Ltd. The blocker 5 can also employ other known structures.

[0029] See Figure 9 , wherein the longitudinal running mechanism 3 includes a wheel seat 3-1, a wheel 3-2 and a reduction motor 3-3; the wheel 3-2 is rotatably mounted on the wheel seat 3-1 and is driven by the reduction motor 3-3 to move, and the wheel 3-2 cooperates with the longitudinal track 1-1 (see Figure 3 or Figure 6 In addition, two safety hooks A are provided in pairs on the wheel seat 3-1. Specifically, the upper ends of the two safety hooks A are welded or fixed to the wheel seat 3-1 by bolts; see Figure 6 The hook portions A-1 at the lower ends of the two safety hooks A are arranged facing each other and extend into the rail waist 1-11 on both sides of the longitudinal track 1-1 to prevent the monorail carrier 2 from derailing from the longitudinal track 1-1. Specifically, the longitudinal track 1-1 is a standard I-shaped steel rail (or iron rail), and the middle part of the longitudinal track 1-1 is the rail waist 1-11. Figure 9 and Figure 6 The wheel 3-2 is provided with an annular groove 3-21 for cooperating with the upper part of the longitudinal track 1-1.

[0030] Specifically, the wheel seat 3-1 is fixed to the bottom of the monorail carrier 2, and the reduction motor 3-3 is mounted on the wheel seat 3-1. The output end of the reduction motor 3-3 is connected to the wheel 3-2. Preferably, the reduction motor 3-3 includes a variable frequency motor and a worm gear reducer. The output end of the variable frequency motor is decelerated by the worm gear reducer and then outputted. The worm gear reducer has a self-locking function, which can keep the wheel 3-2 braked and prevent it from moving when the longitudinal travel mechanism 3 stops moving.

[0031] Specifically, the safety hook A is roughly L-shaped. By providing two safety hooks on the track running mechanism 3, the stability of the monorail carriage on the track is enhanced. The hook portion at the lower end of the safety hook extends into the waist of the longitudinal track, effectively preventing the monorail carriage from derailing during movement. Compared to the existing method of securing the vehicle solely with tie straps, this significantly improves stability, resulting in greater stability, reliability, and safety, and also eliminates the need for manual operation.

[0032] In this embodiment, two pairs of safety hooks A distributed front and back are provided on the wheel seat 3 - 1 of each track running mechanism 3 , which can multiply the safety.

[0033] See Figure 1 and Figure 4 and Figure 7 Preferably, the traction mechanism 4 is a winch, which pulls the straddle-type monorail vehicle N along the monorail beam 2-1 through the wire rope 4-1. The winch has a large traction force and can stably pull the straddle-type monorail vehicle to move on the track beam (see Figure 7 ) to ensure the reliability of the vehicle moving process. A winch is used as the traction mechanism, allowing the straddle-type monorail vehicle to automatically move into position on the track beam. The winch can control the traction speed during movement, performing the reeling motion while the monorail carrier 2 remains stationary. This makes the vehicle moving process more precise and efficient, and reduces labor intensity. Compared with the existing technology that uses a maintenance tractor to travel along the monorail beam 2-1 to pull the straddle-type monorail vehicle N, operation is simpler and safer.

[0034] See Figure 1 and Figure 4 Furthermore, a stopper 2-2 is provided at the front end of the monorail beam 2-1 in the direction of travel of the straddle-type monorail vehicle N, and at least one stopper 5 is mounted on the stopper 2-2. The traction mechanism 4 uses the steel wire rope 4-1 to pull the straddle-type monorail vehicle onto the track beam 2-1. When the vehicle moves to the predetermined position, the stopper 5 comes into play to prevent the vehicle from moving further, ensuring that the vehicle stops accurately at the designated position. Figure 7 . The setting of the block 2-2 and the blocker can effectively prevent the straddle-type monorail vehicle from rushing out of the track beam during the traction process, play a dual protection role, and further improve the safety of the vehicle moving process. When the traction straddle-type monorail vehicle N stops, the brake provided by the winch is used to brake the steel wire rope to keep the straddle-type monorail vehicle N taut, so as to stabilize the position of the straddle-type monorail vehicle N on the track beam 2-1 and ensure its safety. The present invention tows and moves the straddle-type monorail vehicle directly on the track beam, which greatly simplifies the vehicle moving operation process, reduces the operation steps and time, and improves the vehicle moving efficiency.

[0035] See Figure 1 Furthermore, the longitudinal running mechanisms 3 may have 4-12 members symmetrically distributed on the two longitudinal tracks 1-1. In this embodiment, there are four members. The symmetrical distribution of the four running mechanisms allows the monorail carriage to receive uniform force on the longitudinal tracks, ensuring smooth operation of the monorail carriage.

[0036] The working steps of the straddle-type monorail vehicle moving platform in this embodiment are as follows: (I) Preparation stage: Double-track carrier 1 stops at the vehicle pickup position (see Figure 1 ), the longitudinal traveling mechanisms 3 at the bottom of the monorail carrier 2 are started to work simultaneously, and the reduction motor 3-3 of each longitudinal traveling mechanism 3 drives the wheel 3-2 to rotate on its respective longitudinal track 1-1, thereby driving the monorail carrier 2 to move longitudinally along the longitudinal track 1-1 until the monorail beam 2-1 on the monorail carrier 2 is exactly aligned with and contacts the straddle-type monorail vehicle N resting on the vehicle picking track beam to be picked up. (II) Vehicle retrieval stage: The traction mechanism 4 (winch) releases the steel wire rope 4-1 and connects and fixes it to the straddle-type monorail vehicle N. The winch is then started to slowly tighten the steel wire rope 4-1, and the straddle-type monorail vehicle N is pulled along the monorail beam 2-1 by the traction force of the winch. When the straddle-type monorail vehicle N moves to the predetermined position, the blocker 5 at the front end of the monorail beam 2-1 comes into play to prevent it from moving further. At the same time, the brake of the winch is applied to keep the steel wire rope taut, ensuring that the straddle-type monorail vehicle N is stably stopped on the monorail beam 2-1. (III) Vehicle Moving Phase: First, the longitudinal travel mechanism 3 is activated to drive the monorail carrier 2 and the straddle-type monorail vehicle N carried thereon to the middle position on the longitudinal track 1-1 and stop safely. Then, the transverse travel mechanism 1-2 is activated to move the dual-track carrier 1 laterally along the transverse track 1-3 to the target position. At this point, the two longitudinal tracks 1-1 on the dual-track carrier 1 are aligned with the two target tracks at the target position. (IV) Vehicle releasing phase: The longitudinal traveling mechanism 3 is activated to drive the monorail carrier 2 and the straddle-type monorail vehicle N to move along the two longitudinal tracks 1-1 and onto the two target tracks M. At this time, the monorail carrier 2 and the straddle-type monorail vehicle N thereon leave the dual-track carrier 1 together, completing the moving operation of the straddle-type monorail vehicle.

[0037] In this embodiment, since the monorail carrier 2, the longitudinal traveling mechanism 3, the monorail beam 2-1, and the traction mechanism 4 are integrally formed as independent modules, they can be independently separated from the two longitudinal rails 1-1 of the dual-rail carrier (i.e., they can work separately). After separation, only the original dual-rail carrier 1, the transverse rails 1-3 and the transverse traveling mechanism 1-2 working in conjunction therewith are left on the work site. The entirety of the dual-rail carrier 1 functions as another independent module (i.e., the existing dual-rail vehicle moving platform) for moving dual-rail vehicles.

[0038] Compared with the prior art, the present invention has the following significant effects: First, the present invention adds a single-track carrier, a single-track beam, and a matching traction mechanism to the existing double-track carrier, so that the vehicle moving platform can handle both conventional double-track vehicles and the structural characteristics of straddle-type monorail vehicles, achieving dual purposes in one machine. This breaks through the limitation of the traditional vehicle moving platform to a single track type, expands the scope of application, and reduces the equipment purchase cost and site occupancy rate in rail transit operation and maintenance. Secondly, the longitudinal traveling mechanism of the present invention is provided with two safety hooks arranged in pairs on the wheel seat and facing each other, and its hook parts extend into both sides of the longitudinal rail waist to form a mechanical limit structure to prevent the monorail carrier from derailing. Each longitudinal traveling mechanism forms symmetrical protection for the two longitudinal rails respectively; compared with the prior art that simply relies on the contact guidance between the wheel and the longitudinal rail, the newly added paired safety hooks provide combined anti-derailment protection, which is particularly suitable for the stability requirements of straddle-type monorail vehicles when moving. It can effectively overcome the problems of instability such as shaking and imbalance that occur when the monorail carrier moves horizontally under the drive of the transverse traveling mechanism due to its high center of gravity, thereby greatly improving the safety of equipment operation; Third, the present invention utilizes a traction mechanism and a blocker to synergize a winch with a steel wire rope to pull the vehicle. The winch brake works in conjunction with the blocker to achieve combined control of traction, positioning, and braking. The winch boasts high traction force and strong controllability, enabling stable traction of monorail vehicles. Compared to traditional traction methods (such as manual labor or maintenance tractors), the present invention significantly improves the reliability and safety of the vehicle moving process. Fourth, the present invention provides dual protection by providing both position limiting and mechanical blocking by installing a block and a stopper at the front end of the monorail beam. When a vehicle reaches a predetermined position, the stopper and the block work together to prevent the vehicle from running off the track and derailing due to excessive traction, further enhancing safety protection. Fifth, the present invention uses a four-stage process of "prepare - pick up - move - place", combined with the coordinated action of the longitudinal and transverse running mechanisms, to achieve the precise transfer of monorail vehicles between different tracks. While existing dual-track moving platforms can only handle the transverse movement of dual-track vehicles, the present invention can collaboratively complete the movement of monorail vehicles through the combination of longitudinal and transverse movement. This process has clear logic, strong controllability, and improves the efficiency and automation of vehicle movement. Sixth, the monorail carrier of the present invention integrates a longitudinal travel mechanism, monorail beams, and traction mechanism, and as an independent module, can be separated from the dual-track carrier as a whole and work in conjunction with the dual-track carrier. Furthermore, it can be flexibly adjusted to the specifications of the straddle-type monorail vehicle without affecting the dual-track vehicle's moving function. The modular and independent operation facilitates equipment upgrades and maintenance, and is compatible with the moving needs of different types of rail vehicles. Therefore, the invention of this embodiment breaks through the application limitations of the traditional double-track vehicle moving platform, and realizes the efficient operation of straddling monorail vehicle moving while ensuring safety and stability, which is more practical than the existing technology.

[0039] Example 2: This example is a further improvement on Example 1: For reference Figure 10 Furthermore, a brake mechanism B is provided on the wheel seat 3 - 1 of the longitudinal traveling mechanism 3 .

[0040] For reference Figure 10 The brake mechanism B includes two symmetrically arranged clamping arms B-1; two turbines B-2 are respectively provided on the upper parts of the two clamping arms B-1; the two turbines B-2 are rotatably mounted on the wheel seat 3-1, and a worm shaft B-3 is rotatably mounted on the wheel seat 3-1; the worm shaft B-3 has two worm segments (B-31, B-32) with opposite rotation directions and are respectively engaged with the two turbines B-2; the worm shaft B-3 is driven to move by a locking motor B-4 arranged on the wheel seat 3-1; the lower ends of the two clamping arms B-1 are respectively provided with two clamping hooks B-11 and are used to symmetrically clamp or release the two sides of the rail waist 1-11 of the longitudinal rail 1-1 (refer to Figure 11-12 ), when braking, the monorail carrier 2 is positioned and locked on the longitudinal track 1-1 through the self-locking characteristics of the worm wheel B-2 and the worm shaft B-3.

[0041] Specifically, both ends of the worm shaft B-3 are rotatably mounted on two supports on the wheel seat 3-1, the locking motor B-4 is fixedly mounted on the wheel seat 3-1, and the output end of the locking motor B-4 is connected to the worm shaft B-3 and drives it to rotate.

[0042] For reference Figure 10 Since the brake mechanism drives the worm shaft to rotate through the locking motor, the two worm segments (B-31, B-32) of the worm shaft B-3 with opposite rotation directions are engaged with the two turbines to drive the two clamping arms B-1 to rotate symmetrically, so that the clamping hooks B-11 symmetrically clamp the rail waist 1-11 of the longitudinal rail 1-1, which can further fix the monorail carrier 2 during the moving process, enhance the overall stability of the moving platform, and prevent the monorail carrier 2 from lateral displacement, longitudinal displacement or shaking during the movement.

[0043] For reference Figure 10In this embodiment, a pair of safety hooks A and a brake mechanism B are located in front and behind the wheel seat 3-1 of each track running mechanism 3. When the track running mechanism 3 is running, the brake mechanism B is released, causing the two clamping hooks B-11 to approach the rail web 1-11 of the longitudinal rail 1-1, leaving a small gap. In this state, the self-locking properties of the worm gear B-2 and the worm shaft B-3 enable the brake mechanism B to function similarly to the pair of safety hooks A, providing protection. If one fails, the other can still provide protection.

[0044] For reference Figure 10 When the track travel mechanism 3 stops and brakes, a brake mechanism B is used to brake to avoid lateral movement, longitudinal movement and shaking during lateral displacement, while a pair of safety hooks A are used for auxiliary safety protection.

[0045] This embodiment enhances the stability of the moving platform in many aspects through the coordinated combination of multiple track walking mechanisms 3, and the paired safety hooks A and brake mechanisms B thereon, which can effectively prevent shaking, slipping, and offsetting during the moving process, greatly improving the safety of the moving.

[0046] This embodiment uses a winch as a traction mechanism, a reduction motor to drive the walking mechanism, and an electrically controlled brake mechanism, etc., to achieve a high degree of automation in the vehicle moving process, reduce manual intervention, improve work efficiency, reduce labor costs and safety risks, and because it is completed automatically, the operation process is more convenient, labor-saving, safe and efficient.

[0047] Example 3: This example is a further improvement based on Example 1 or 2: For reference Figure 13 Furthermore, a U-shaped groove 2-3 with a downward opening is provided in the middle of the monorail carrier 2, and a counterweight 6 is provided in the U-shaped groove 2-3. The overall weight of the monorail carrier 2 can be increased, and the center of gravity can be lowered. In this way, when the monorail carrier is equipped with a straddle-type monorail vehicle, the shaking caused by the high center of gravity of the vehicle can be reduced, and the counterweight can lower the overall center of gravity, offset the unbalanced torque generated by the weight of the vehicle, and enhance the stability of the monorail carrier during the vehicle moving process. Especially when the lateral walking mechanism drives the double-track carrier to move horizontally, the counterweight can reduce the risk of the monorail carrier's rollover, avoid shaking and imbalance problems caused by the shift of the center of gravity, and significantly improve its safety compared to the structure without a counterweight.

[0048] Example 4: This example is a further improvement based on Example 1 or 2: For reference Figure 14The middle portion of the counterweight 6 is rotatably connected to the inner top wall of the U-shaped groove 2-3 via a swing arm 7. Specifically, the upper end of the swing arm 7 is rotatably connected to the inner top wall of the U-shaped groove 2-3 and is fixedly connected to the counterweight 6. During the vehicle movement phase, when the transverse traveling mechanism 1-2 drives the dual-track carriage 1 to translate along the transverse track 1-3, the single-track carriage 2 is prone to lateral tilt or upward tilt due to factors such as inertia and uneven load distribution. At this time, the counterweight 6 automatically swings based on the rotating fulcrum at the upper end of the swing arm 7 under the action of gravity and centrifugal force: if the left side of the monorail carrier 2 has an upward trend, the counterweight 6 will swing to the lower left, and the torque generated by its gravity and the upward trend will form an opposite couple to quickly offset the unbalanced torque; on the contrary, if the right side tilts, the counterweight 6 will swing to the lower right to achieve dynamic center of gravity adjustment, which can achieve adaptive swing adjustment. Compared with fixed counterweights, it can be more timely and effective, and can significantly reduce the risk of rollover caused by lateral movement; the structure is simplified, does not require control, has low cost, can also reduce equipment failure rate, reduce maintenance costs, and effectively improve the safety of vehicle moving.

[0049] Specifically, the counterweight 6 is in the shape of an elongated strip, with its length direction being the longitudinal direction.

[0050] Example 5: See Figure 15 A vehicle moving method, based on the straddle-type monorail vehicle moving platform described in any one of the above embodiments 1 to 4, comprises the following steps: S10 preparation stage: the double-track carrier 1 is parked at the vehicle pickup position (combined with Figure 15 and Figure 1 The longitudinal traveling mechanism 3 is activated to drive the monorail carriage 2 along the longitudinal track 1-1, so that the monorail beam 2-1 is aligned with the straddle-type monorail vehicle N to be picked up. Specifically, the end of the monorail beam 2-1 away from the traction mechanism 4 is aligned with the end of the track beam 20 on which the straddle-type monorail vehicle N to be picked up is resting (i.e., connected end to end).

[0051] S20 Vehicle Pickup Stage: The traction mechanism 4 (hoist) releases the wire rope 4-1 and connects it to the straddle-type monorail vehicle N. The traction mechanism 4 is activated to pull the straddle-type monorail vehicle N along the monorail beam 2-1. When the straddle-type monorail vehicle N reaches a predetermined position, it is stopped by the blocker 5. Simultaneously, the traction mechanism 4 (because the hoist has its own brake) brakes and secures the straddle-type monorail vehicle N. S30 Moving stage: Start the longitudinal traveling mechanism 3 and move the monorail carrier 2 and the straddle-type monorail vehicle N to the middle position of the longitudinal track 1-1 (see Figure 5-7); then start the transverse traveling mechanism 1-2 to translate the double-track carrier 1 (which now carries the single-track carrier 2 and the straddle-type monorail vehicle N and moves together) along the transverse track 1-3 to the target position, so that the two longitudinal tracks 1-1 are aligned with the two target tracks M (connected end to end); S40: The vehicle placement phase is to start the longitudinal travel mechanism 3 and drive the monorail carrier 2 and the straddle-type monorail vehicle N to move along the two longitudinal tracks 1-1 and enter the two target tracks M, completing the vehicle transfer. Figure 8 and Figure 15 .

[0052] See Figure 8 and 15 When the single-track carrier 2 leaves the two longitudinal tracks 1-1, only the original double-track carrier 1, and the transverse tracks 1-3 and transverse running mechanism 1-2 working together therewith are left on the work site, and the existing double-track vehicles can be moved.

[0053] Furthermore, during the vehicle moving stage, the brake mechanism B of the longitudinal traveling mechanism 3 is released when the straddle-type monorail vehicle N moves; when the straddle-type monorail vehicle N stops, the clamping hooks B-11 of its two clamping arms B-1 clamp the rail waist 1-11 of the longitudinal rail 1-1 to fix the monorail carrier 2.

[0054] Furthermore, during the preparation stage and the vehicle moving stage, the hook portions A-1 at the lower ends of the two safety hooks A always extend into both sides of the rail waist 1-11 of the longitudinal track 1-1 to prevent the monorail carrier 2 from derailing.

[0055] The existing monorail vehicle moving method requires 6-8 tedious steps, including "vehicle loading - assembly pushing - tying and fixing - manual vehicle moving - tying and untying - second pushing", and relies on the collaborative operation of 5-10 staff members.

[0056] The vehicle moving method of the present invention adopts a four-stage process (preparation - vehicle retrieval - vehicle moving - vehicle placement), streamlining the steps to four core links. Combined with the automated drive of the longitudinal / lateral walking mechanism, the moving time of N straddle-type monorail vehicles is improved by 50% or more compared to the traditional method in terms of work efficiency. Only one or two people are needed to complete the process. This can simultaneously solve the problems of existing vehicle moving methods such as high labor intensity, low work efficiency, poor safety, and insufficient compatibility.

[0057] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art through logical analysis, reasoning, or limited experimentation based on the concepts of the present invention and the prior art should be within the scope of protection defined by the claims.
