Description

Technical Field

[0001] This utility model belongs to the technical field of railway transportation equipment, specifically relating to a railway monorail transport vehicle. Background Technology

[0002] With the rapid development of railway construction and infrastructure, heavy items inevitably need to be transported during the construction process. However, in some special railway transportation needs, the traditional double-track railway transportation system may have problems such as large land area, high construction cost, and limited flexibility. For example, it is difficult to lay double-track railways in some areas with complex terrain and narrow space. The existing single-track transportation mode is still insufficient in terms of load-bearing capacity, operational stability, and safety, and cannot meet the diverse transportation needs. Therefore, a new type of railway single-track transport vehicle is needed.

[0003] Currently, there is a railway monorail transport vehicle in the industry. For example, Chinese patent CN 208233047 U discloses a railway monorail transport vehicle, which includes a storage tray frame, track wheels and a lever handle. The storage tray frame is a rectangular tray frame welded from metal. The track wheels are welded to the side frame of the storage tray frame via wheel axles. The lever handle is welded to the side frame of the same side. The storage tray frame also includes a sleeve welded to it and a hook that can pass through the sleeve.

[0004] The aforementioned patent CN 208233047 U still has the following technical shortcomings in practical application: On the one hand, the monorail transport vehicle does not have an assist system, so it often requires two or more people to complete the transport process, especially on uphill tracks, which can easily lead to transport difficulties or even failures, resulting in low work efficiency and significantly reduced construction speed. On the other hand, the monorail transport vehicle's storage tray does not have a matching item clamping device, so items on the storage tray are very likely to slip off the surface during transport, which not only further reduces work efficiency and construction speed, but also poses certain safety hazards.

[0005] Therefore, designing a railway monorail transport vehicle with a power assist system, a compression device, and ease of use is of great practical significance. Utility Model Content

[0006] The purpose of this utility model is to provide a railway monorail transport vehicle to solve the technical problems in the background art, namely: "On the one hand, existing railway monorail transport vehicles do not have an assist system, so during the transportation process, two or more people are often needed to complete the transportation, especially on uphill tracks, which can easily lead to transportation difficulties or even transportation failures, resulting in low work efficiency and a significant reduction in construction speed; on the other hand, the existing monorail transport vehicle's storage tray does not have a matching item clamping device, so during transportation, items on the storage tray are very likely to slip off the surface, which not only further reduces work efficiency and construction speed, but also poses certain safety hazards."

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A railway monorail transport vehicle includes a loading platform frame, a drive wheel, a driven wheel, a drive mechanism, a power supply, a clamping mechanism, and a lever handle;

[0009] The drive wheel is located at the front end of the bottom of the storage platform frame, and the driven wheel is located at the rear end of the bottom of the storage platform frame. The drive mechanism and power supply are located on the storage platform frame. The drive wheel is connected to the drive mechanism, and the drive mechanism is connected to the power supply. The drive wheel can drive the driven wheel to move back and forth along the transport track through the drive mechanism.

[0010] The tightening mechanism includes a fastening band and a tightening element;

[0011] The fastening strap is located near one side of the storage platform frame, and the tightening member is located near the other side of the storage platform frame; one end of the fastening strap is fixed to the storage platform frame, and the other end of the fastening strap passes through the tightening member, for fastening goods transported on the storage platform frame;

[0012] The bottom end of the lever handle is fixed to the storage platform frame, and the lever handle is located near the side frame of the drive wheel.

[0013] The above technical solution offers the following advantages: Compared to existing technologies, this railway monorail transport vehicle effectively improves the overall structure and assembly method of the loading platform frame, driving wheel, driven wheel, drive mechanism, power supply, clamping mechanism, and lever handle. The arrangement of the driving wheel and driven wheel provides a stable walking structure for the railway monorail transport vehicle. The drive mechanism and power supply are located on the loading platform frame, ensuring a stable power supply. The power supply provides electrical energy to the drive mechanism, which is directly connected to the driving wheel, reducing energy loss during power transmission. Driven by the drive mechanism, the driving wheel can effectively transmit power to the driven wheel, enabling the entire transport vehicle to move back and forth along the transport track. By adding a clamping mechanism to the loading platform frame... The tightening mechanism ensures the safety of transported goods. One end of the fastening strap is fixed to the loading platform frame, and the other end passes through the tightening element. The tightening element can tighten the fastening strap, so that goods of both regular and irregular shapes can be effectively fixed to the loading platform frame. During transportation, even if there are bumps on the track or the acceleration and deceleration of the transport vehicle, the goods will not shift or fall off. By setting lever handles on the edge of the loading platform frame, the operation of the transport vehicle is facilitated. The operator can easily pry the transport vehicle using the lever principle. When starting, stopping, or adjusting the position of the transport vehicle, the lever handles provide a labor-saving and convenient operating point. To address the technical problems in the background technology, namely: "On the one hand, existing railway monorail transport vehicles do not have an assist system, so during transportation, two or more people are often required to complete the transport, especially on uphill tracks, which can easily lead to transportation difficulties or even failures, resulting in low work efficiency and significantly reduced construction speed; on the other hand, the existing monorail transport vehicles do not have matching item clamping devices on the storage trays, so during transportation, items on the storage trays are very likely to slip off the surface, which not only further reduces work efficiency and construction speed, but also poses certain safety hazards."

[0014] In a preferred embodiment, the drive mechanism includes a servo motor, a reducer, and an adjustment switch;

[0015] The servo motor is connected to the power supply via the adjustment switch. The output end of the servo motor is connected to the input end of the reducer. The drive wheel is connected to the output end of the reducer. The adjustment switch is located on the lever handle and is positioned near the top of the lever handle.

[0016] The above technical solution offers the following advantages: By employing a servo motor, reducer, and adjustment switch in the drive mechanism, the servo motor possesses high-precision position control capabilities, enabling it to quickly and accurately adjust its speed according to commands. The reducer effectively amplifies torque within the drive mechanism. While the servo motor's torque output is limited, when paired with a reducer of appropriate gear ratio, it can multiply the torque. This is crucial for overcoming resistance during the start-up and operation of railway monorail transport vehicles. For example, when starting a fully loaded transport vehicle, the increased torque easily overcomes the static friction between the wheels and the rails, as well as the inertia of the cargo, allowing the transport vehicle to start smoothly. Furthermore, the adjustment switch allows for flexible adjustment of the servo motor's output power based on the load requirements of the actual working scenario, ensuring the stability and reliability of the transport vehicle during transport.

[0017] In a preferred embodiment, the reducer includes a reduction gearbox, a first gear, and a second gear;

[0018] The first gear and the second gear are coaxially disposed inside the gearbox, and the number of teeth or radius of the first gear is greater than the number of teeth or radius of the second gear.

[0019] The above technical solution has the following advantages: by using a combination of a gearbox, a first gear, and a second gear in the reducer, and with the first gear and the second gear being coaxially arranged, and the number of teeth or radius of the first gear being greater than the number of teeth or radius of the second gear, the reduction function can be achieved, the torque output can be increased, and the transmission accuracy can be improved.

[0020] In a preferred embodiment, the output end of the servo motor is provided with a third gear, which meshes with the first gear, and the number of teeth or radius of the third gear is smaller than the number of teeth or radius of the first gear.

[0021] The above technical solution has the following advantages: By providing a third gear at the output end of the servo motor and meshing it with the first gear, the power of the servo motor is transmitted to the first gear through the third gear, and then from the first gear to the coaxially arranged second gear; by making the number of teeth or the radius of the third gear smaller than that of the first gear, the transmission speed and torque output of the servo motor are adjusted by the ratio of the number of teeth or the radius of the third gear to that of the first gear.

[0022] In a preferred embodiment, the driving wheel is provided with a fourth gear, which meshes with the second gear, and the number of teeth or radius of the fourth gear is greater than the number of teeth or radius of the second gear.

[0023] The above technical solution has the following advantages: by providing a fourth gear on the drive wheel and having the fourth gear mesh with the second gear, the power of the drive mechanism is stably transmitted to the drive wheel, thereby ensuring that the drive mechanism drives the transport vehicle to move forward and backward along the transport track, achieving an assist effect; by having the number of teeth or radius of the fourth gear be greater than the number of teeth or radius of the second gear, the forward or backward speed of the transport vehicle can be adjusted by the ratio of the number of teeth or the radius of the fourth gear to the second gear.

[0024] In a preferred embodiment, the lever handles are provided in several quantities and are welded to the frame of the storage platform.

[0025] The above technical solution has the following advantages: by welding several lever handles onto the frame of the loading platform, the balance and stability of the transport vehicle during transportation can be further ensured and increased. That is, the stability of the transport vehicle during the journey can be maintained by manually holding any lever handle and prying it left or right.

[0026] In a preferred embodiment, the number of tightening mechanisms is several, and they are respectively installed on the storage platform frame.

[0027] The above technical solution has the following advantages: by setting several clamping mechanisms on the storage platform, it is further ensured that the items on the storage tray will not slip off the surface during transportation, thereby ensuring high work efficiency, greatly improving construction speed, and ensuring a certain level of safety.

[0028] In a preferred embodiment, the driving wheel and the driven wheel are made of nylon material.

[0029] The above technical solution has the following advantages: by using nylon material to make the driving wheel and driven wheel, the damage to the track by the driving wheel and driven wheel is reduced. The hardness of nylon material is moderate. Compared with some wheels made of metal materials with higher hardness, the hardness difference between it and the track is more reasonable. When the driving wheel and driven wheel are running on the track, the nylon wheel will not cause serious scratches and wear on the track surface like wheels with excessive hardness.

Detailed Implementation

[0037] Example 1

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the embodiments.

[0039] like Figures 1 to 4 As shown, a railway monorail transport vehicle includes a loading platform frame 1, a driving wheel 2, a driven wheel 3, a drive mechanism 4, a power supply 5, a tightening mechanism 6, and a lever handle 7.

[0040] The driving wheel 2 is located at the front end of the bottom of the storage platform frame 1, and the driven wheel 3 is located at the rear end of the bottom of the storage platform frame 1. The drive mechanism 4 and the power supply 5 are located on the storage platform frame 1. The driving wheel 2 is connected to the drive mechanism 4, and the drive mechanism 4 is connected to the power supply 5. The driving wheel 2 can drive the driven wheel 3 to move back and forth along the transport track through the drive mechanism 4.

[0041] The tightening mechanism 6 includes a fastening band 61 and a tightening element 62;

[0042] The fastening strap 61 is set on one side of the edge of the storage platform frame 1, and the tightening member 62 is set on the other side of the edge of the storage platform frame 1; one end of the fastening strap 61 is fixed on the storage platform frame 1, and the other end of the fastening strap 61 passes through the tightening member 62, and is used to fasten the goods transported on the storage platform frame 1.

[0043] The bottom end of the lever handle 7 is fixed to the loading platform frame 1, and the lever handle 7 is located near the side frame of the drive wheel 2. The arrangement of the drive wheel 2 and the driven wheel 3 provides a stable walking structure for the railway monorail transport vehicle. The drive mechanism 4 and the power supply 5 are located on the loading platform frame 1. This layout ensures a stable power supply. The power supply 5 provides electrical energy to the drive mechanism 4, which is directly connected to the drive wheel 2, reducing energy loss during power transmission. Under the drive of the drive mechanism 4, the drive wheel 2 can effectively transmit power to the driven wheel 3, enabling the entire transport vehicle to move back and forth along the transport track. By adding a clamping mechanism 6 to the loading platform frame 1, the design of the clamping mechanism 6 ensures the stability of the transported goods. For safety, one end of the fastening strap 61 is fixed to the storage platform frame 1, and the other end passes through the tightening member 62. The tightening member 62 can tighten the fastening strap 61, so that goods of both regular and irregular shapes can be effectively fixed to the storage platform frame 1. During transportation, even if there are bumps on the track or the acceleration and deceleration of the transport vehicle, the goods will not shift or fall off. By setting the lever handle 7 on the edge of the storage platform frame 1, the operation of the transport vehicle is facilitated. The operator can easily pry the transport vehicle using the lever principle. When starting, stopping or adjusting the position of the transport vehicle, the lever handle 7 provides a labor-saving and convenient operating point.

[0044] In this embodiment, the drive mechanism 4 includes a servo motor 41, a reducer 42, and an adjustment switch 43;

[0045] The servo motor 41 is connected to the power supply 5 via the adjustment switch 43. The output end of the servo motor 41 is connected to the input end of the reducer 42, and the drive wheel 2 is connected to the output end of the reducer 42. The adjustment switch 43 is located on the lever handle 7, near the top of the lever handle 7. By using the servo motor 41, reducer 42, and adjustment switch 43 in the drive mechanism 4, the servo motor 41 has high-precision position control capability, which can quickly and accurately adjust the speed according to the command. The reducer 42 can effectively amplify the torque in the drive mechanism 4. The torque output of the servo motor 41 is limited, but when it is matched with a reducer 42 with a suitable gear ratio, the torque can be amplified many times. This is crucial for overcoming resistance during the start-up and operation of the railway monorail transport vehicle. For example, when starting a transport vehicle fully loaded with heavy loads, the increased torque can easily overcome the static friction between the wheels and the rails and the inertia of the cargo, allowing the transport vehicle to start smoothly. By adjusting the switch 43, the output power of the servo motor 41 can be flexibly adjusted according to the load requirements of the actual working scenario to ensure the stability and reliability of the transport vehicle during transportation.

[0046] In this embodiment, the reducer 42 includes a reduction gearbox 421, a first gear 422, and a second gear 423;

[0047] The first gear 422 and the second gear 423 are coaxially arranged inside the reduction gearbox 421. The number of teeth or radius of the first gear 422 is greater than that of the second gear 423. By combining the reduction gearbox 421, the first gear 422 and the second gear 423 in the reduction gear 42, and setting the first gear 422 and the second gear 423 coaxially, and ensuring that the reduction function, torque output and transmission accuracy are achieved, the reduction function is increased.

[0048] In this embodiment, the output end of the servo motor 41 is provided with a third gear 411, which meshes with the first gear 422. The number of teeth or radius of the third gear 411 is smaller than the number of teeth or radius of the first gear 422. By providing a third gear 411 at the output end of the servo motor 41 and meshing with the first gear 422, the power on the servo motor 41 is ensured to be transmitted to the first gear 422 through the third gear 411, and then transmitted from the first gear 422 to the coaxially arranged second gear 423. By ensuring that the number of teeth or radius of the third gear 411 is smaller than the number of teeth or radius of the first gear 422, the transmission speed and torque output of the servo motor 41 are adjusted by the ratio of the number of teeth or the radius of the third gear 411 to the first gear 422.

[0049] In this embodiment, a fourth gear 21 is provided on the drive wheel 2, and the fourth gear 21 meshes with the second gear 423. The number of teeth or radius of the fourth gear 21 is greater than the number of teeth or radius of the second gear 423. By providing a fourth gear 21 on the drive wheel 2 and having the fourth gear 21 mesh with the second gear 423, the power on the drive mechanism 4 is stably transmitted to the drive wheel 2, thereby ensuring that the drive mechanism 4 drives the transport vehicle to move back and forth along the transport track, achieving an assist effect. By ensuring that the number of teeth or radius of the fourth gear 21 is greater than the number of teeth or radius of the second gear 423, the forward or backward speed of the transport vehicle can be adjusted by the ratio of the number of teeth or the ratio of the radius of the fourth gear 21 to the second gear 423.

[0050] In this embodiment, a number of lever handles 7 are provided and are welded to the frame of the storage platform 1. By welding a number of lever handles 7 to the frame of the storage platform 1, the balance and stability of the transport vehicle during transportation are further ensured. That is, the stability of the transport vehicle during the journey can be maintained by manually holding any lever handle 7 and prying it left and right.

[0051] In this embodiment, a number of compression mechanisms 6 are provided, and they are respectively provided on the storage platform 1. By providing a number of compression mechanisms 6 on the storage platform 1, it is further ensured that the items on the storage platform 1 will not slip off the surface during transportation, thereby ensuring high work efficiency, greatly improving construction speed, and ensuring a certain level of safety.

[0052] In this embodiment, the driving wheel 2 and the driven wheel 3 are made of nylon material. By using nylon material for the driving wheel 2 and the driven wheel 3, damage to the track by the driving wheel 2 and the driven wheel 3 is reduced. The hardness of nylon material is moderate. Compared with some wheels made of metal materials with higher hardness, the hardness difference between it and the track is more reasonable. When the driving wheel 2 and the driven wheel 3 run on the track, the nylon wheel will not cause serious scratches and wear on the track surface like wheels with excessive hardness.
