DETAILED DESCRIPTION

[0025] In order to better understand and implement, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing specific embodiments of the present application, and are not intended to limit the present application.

[0028] In order to better understand the technical concept of the present application, the problems encountered before the present application will be described simply. In the prior art, the structure of the monorail transport vehicle is realized by using a set of gear and rack assemblies to realize the transport movement. In actual use, it is found that the monorail transport vehicle with such structure moves very unstably, for example, the problems of jolting or shaking are prone to occur.

[0029] By comparison, a transport device according to the embodiments of the present application is developed to solve the above-mentioned problems encountered in the prior art.

[0030] The transport device according to the embodiments of the present application will be described in detail below in combination with Figures 1-3 The transport device according to the embodiments of the present application will be described in detail below in combination with Figure 1 Fig. 1 is a front view of the present transport device, Figure 2 Fig. 2 is a left view of the present transport device, Figure 3 Fig. 3 is a structural schematic view of the present transport device, and in order to better observe the driving structure and the roller structure, the support frame is intentionally hidden by half.

[0031] Specifically, the present transport device specifically comprises a single rail 1 and a frame 2.

[0032] The single track 1 is fixed with a rack 14.

[0033] The frame body 2 comprises an upper and lower fixed load-bearing frame 21 and a support frame 22, and the support frame 22 is provided with a roller structure and a driving structure to enable the frame body 2 to move on the single track 1.

[0034] The driving structure comprises a driving gear 31, a driven gear 32 and a motor, the driving gear 31 and the driven gear 32 are arranged along the length direction of the single track 1 and are both engaged with the rack 14, the motor is fixed on the support frame 22, the driving end of the motor is drivingly connected with a driving shaft 33, the driving gear 31 is fixed on the driving shaft 33, and the driven gear 32 is connected to the support frame 22 through a driven shaft 34.

[0035] The working principle of the transportation device is that when the motor is started, the driving end of the motor drives the driving shaft 33 to rotate, and the driving gear 31 fixed on the driving shaft 33 rotates as well. Since the driving gear 31 and the driven gear 32 are both engaged with the rack 14 fixed on the lower end surface of the top track section 11 of the single track 1, when the driving gear 31 rotates, it moves along the length direction of the rack 14 by the meshing transmission principle of the gear and the rack 14, and simultaneously drives the driven gear 32 to rotate, thereby enabling the entire frame body 2 to move smoothly along the length direction of the single track 1.

[0036] Therefore, compared with the single track 1 transportation vehicle in the prior art which only uses one set of gear and rack assembly to realize transportation movement, the transportation device of the present application is provided with the driving gear 31 and the driven gear 32 which are engaged with the rack 14, which is equivalent to providing two sets of gear and rack assemblies, and the two sets of gear and rack assemblies share one rack 14; one set is the driving gear and rack assembly for providing power, and the other set is the driven gear and rack assembly for balancing to improve stability; therefore, when driving movement, the power can be transmitted more evenly, thereby effectively reducing the problem of bumping or shaking during transportation, greatly improving the stability of the transportation device movement; and the stable transportation process can also avoid damage to the goods due to bumping, ensuring the safety of transportation and the integrity of the goods.

[0037] At the same time, due to the stable movement and stable structure, the transportation device can be applied to the transportation of more types of goods, whether heavy industrial parts or precision instruments with high requirements for transportation environment, etc., can better complete the transportation task, expand its application range in different industrial production, logistics transportation, etc., such as transporting materials, equipment, etc. on the building roof, and even transporting personnel; and the use position is not limited to the roof, but also to the ground, steep slope, etc., and after the stability is improved, the application range is wider.

[0038] More importantly, the transport device adopts a monorail 1 structure, has a small footprint, and is very suitable for occasions where the ground area is small and the weight of the lifted object is large.

[0039] Optionally, one end of the driving shaft 33 can be fixedly connected with the driving gear 31, and the other end can be rotatably connected to the support frame 22 through a bearing, and the support frame 22 provides a support force to the driving shaft 33 to improve the stability of the structure.

[0040] Optionally, one end of the driven shaft 34 can be fixedly connected with the driven gear 32, and the other end can also be rotatably connected to the support frame 22 through a bearing, and the support frame 22 provides a support force to the driven shaft 34 to improve the stability of the structure.

[0041] Specifically, the monorail 1 has an I-shaped structure and sequentially includes a top rail segment 11, a middle rail segment 12, and a bottom rail segment 13 from top to bottom, and the lower end surface of the top rail segment 11 is fixedly connected with a rack 14.

[0042] The rack 14 is located below the top rail segment 11, and the function of power transmission is realized without occupying too much additional space. Through the meshing of the gear and the rack 14, the power of the motor can be effectively converted into the moving power of the transport device on the monorail 1. Compared with other possible driving modes, this design is compact and efficient, can realize stable driving in a limited space, and is conducive to the miniaturization and high-efficiency design of the transport device. Moreover, during installation and maintenance, technicians can easily check and adjust the gear and rack 14. Moreover, this positional relationship can ensure that the gear and rack 14 maintain good meshing state during transmission, reducing problems such as poor meshing and tooth skipping due to improper position.

[0043] Specifically, the roller structure includes a load wheel 41 and a stabilizing wheel 42, the load wheel 41 is connected to the support frame 22 through a load shaft 411, and the load wheel 41 rolls on the top of the top rail segment 11, and the stabilizing wheel 42 is connected to the support frame 22 through a stabilizing shaft 421, and the stabilizing wheel 42 rolls on the side of the middle rail segment 12.

[0044] During the movement of the frame body 2, the roller structure plays an important supporting and stabilizing role. The load wheel 41 is connected to the support frame 22 through the load shaft 411, and it rolls on the top of the top rail segment 11 of the monorail 1, and bears most of the weight of the frame body 2 and the transported goods, etc., similar to the pier of a bridge, providing main load-bearing support for the entire transport device.

[0045] The stabilizing wheel 42 is connected to the support frame 22 through a stabilizing shaft 421, and rolls on the side of the middle rail section 12 of the monorail 1 to provide a lateral support force to the frame 2 from the side, limit the shaking of the frame 2, and ensure that the frame 2 moves smoothly along the established direction of the monorail 1 during movement, avoiding unstable conditions such as deviation from the track, just like the side guide wheels of a car that help maintain the stability of the vehicle during straight driving.

[0046] Moreover, the cooperation of the load wheels 41 and the stabilizing wheels 42 in the roller structure supports and limits the frame 2 from the top and bottom and from the side, with the load wheels 41 responsible for bearing the weight and the stabilizing wheels 42 assisting in maintaining lateral stability. More importantly, the load wheels 41, the top rail section 11 of the frame 2, the rack 14, the driving gear 31, and the driven gear 32 also form a stable transportation structure, making the entire transportation device more stable when running on the monorail 1. Even if the track is uneven to some extent or there is slight external interference, the device can still maintain good running conditions, reducing the probability of accidents such as derailment, and improving the overall reliability and service life of the device.

[0047] Specifically, the rack 14 and the driving structure are both provided with two, and the driving gear 31 and the driven gear 32 in one driving structure correspondingly engage with one rack 14.

[0048] Among them, double driving can be formed to work cooperatively, and the two driving structures work simultaneously, cooperatively providing driving force to the frame 2 to move along the monorail 1. When encountering changes in load or local unevenness of the track affecting power transmission, the two driving structures can compensate for each other to ensure stable output of driving force, reduce problems such as device jamming and speed fluctuations caused by insufficient or instantaneous lack of power, and maintain a relatively constant speed during transportation to ensure the stability of transportation efficiency. At the same time, the power driving force is more balanced, and the goods are less likely to tip over.

[0049] Moreover, the two driving structures engage with the corresponding racks 14 from different positions to drive the frame 2, applying driving force to the frame 2 from different angles to better balance the stress on the frame 2 and further reduce unstable phenomena such as left-right shaking and up-down bouncing of the transportation device during operation. Especially when transporting some items that require high stability, such as high-precision electronic equipment and optical instruments, this double driving structure can minimize vibrations during transportation, providing a more stable transportation environment for the items and preventing damage to the items due to shaking, thereby improving transportation quality.

[0050] Specifically, the two racks 14 are symmetrically arranged relative to the monorail 1, and the two driving structures are symmetrically arranged relative to the monorail 1.

[0051] The symmetrically arranged rack 14 and driving structure maximally ensure the force balance of the frame 2 during operation. During transportation, whether the goods are empty or full of different weights and different distributions, the driving structures on both sides can uniformly provide driving force, avoiding the situation that one side bears more force and the other side bears less force, so that the frame 2 will not tilt, deviate, and the like, and the instability phenomenon such as shaking and jolting caused by uneven force is reduced from the root, ensuring the accuracy and stability of the movement trajectory of the transportation device, just like the balance when the same weight objects are placed on both ends, which provides a strong guarantee for the stability of transportation.

[0052] Specifically, the load wheels 41 are provided with two, and the two load wheels 41 are arranged in the length direction of the monorail 1.

[0053] Among them, when the transportation device is working, the weight of the frame 2 and the goods carried by the frame 2 is transmitted to the load wheels 41 through the support frame 22. The two load wheels 41 are like two support points, which disperse the total weight. Each load wheel 41 rolls on the top of the monorail 1 top rail section 11, and each of them bears a part of the weight, so that the pressure borne by each load wheel 41 is within its carrying capacity, thereby ensuring that the entire transportation device can be stably supported. And, the two load wheels 41 can share heavier loads because they can more reasonably distribute the weight, avoiding damage to a single load wheel 41 bearing excessive pressure, which enables the transportation device to transport heavier goods, expanding its application range in industrial transportation and the like, for example, it can be used to transport heavy goods such as large mechanical parts.

[0054] At the same time, when the surface of the monorail 1 is uneven or slight vibration occurs during transportation, the two load wheels 41 can play a buffering and balancing role, for example, the two load wheels 41 can be displaced up and down differently according to the actual situation of the monorail 1, so that the frame 2 can better maintain a horizontal state, further reducing jolting and shaking, and providing a more stable transportation environment for the goods being transported.

[0055] Specifically, the stabilizing wheels 42 are provided with four, and each two of the stabilizing wheels 42 form a wheel group, and the two wheel groups are arranged in the length direction of the monorail 1.

[0056] When the frame 2 has a tendency to deviate to the side during the operation of the transport device, the stabilizing wheels 42 located on the side of the middle rail section 12 of the monorail 1 will play a role. The two stabilizing wheels 42 of the same group jointly resist the middle rail section 12 from the side, providing a lateral support force to limit the lateral movement of the frame 2. Moreover, the two groups of wheels are arranged in intervals, and they respectively provide lateral support to the frame 2 at different positions. The two groups of stabilizing wheels 42 work together to correct the position of the frame 2 according to the deviation direction and degree of the frame 2, through the friction and support force of the stabilizing wheels 42 and the side of the middle rail section 12, so as to keep the frame 2 in the correct position of the monorail 1.

[0057] It can be seen that the arrangement of two groups of stabilizing wheels 42 can greatly enhance the lateral stability of the transport device. The interval arrangement of the four stabilizing wheels 42 can provide more powerful and balanced lateral support force from multiple angles and positions, which makes the transport device have stronger resistance to various factors that may cause lateral deviation (such as lateral wind, deviation of the center of gravity of the transported goods, etc.), effectively reduces the lateral shaking of the frame 2 on the monorail 1, and ensures the safety and stability of the transportation process.

[0058] Specifically, the two stabilizing wheels 42 in each group are symmetrically arranged relative to the monorail 1.

[0059] The symmetric arrangement of the two stabilizing wheels 42 in each group relative to the monorail 1 can provide the most accurate lateral balance. This symmetric structure can ensure that the support force provided by the two stabilizing wheels 42 is uniform and balanced under any lateral force, thereby effectively avoiding the tilting of the frame 2 caused by uneven lateral support force, ensuring that the horizontal state of the goods during transportation is not affected, and greatly improving the quality and safety of transportation.

[0060] Moreover, the symmetrically arranged stabilizing wheels 42 also enhance the ability of the transport device to resist lateral interference. Since the two stabilizing wheels 42 can simultaneously and evenly respond to lateral forces, whether it is a sustained lateral wind force or an instantaneous lateral impact, the transport device can better maintain stability on the monorail 1. For example, in outdoor transportation scenarios, different directions and intensities of wind may be encountered. This symmetric stabilizing wheel 42 structure can effectively resist the lateral influence of wind on the transport device, reduce shaking and deviation, and ensure the smooth progress of the transportation process.

[0061] Specifically, the load shaft 411 is eccentrically arranged relative to the load wheel 41.

[0062] The most direct benefit of the eccentricity of the load shaft 411 is to improve the transmission accuracy of the gear and rack 14. With this arrangement, the center distance of both the gear and rack 14 is adjusted, the backlash is eliminated, the precise contact of the gear and rack 14 is ensured, the rotation of the gear can be accurately converted into the linear movement of the frame 2 on the monorail 1, and the stability of the operation is further ensured.

[0063] Specifically, the stabilizing shaft 421 is eccentrically arranged relative to the stabilizing wheel 42.

[0064] The eccentricity of the stabilizing shaft 421 can improve the stability of the contact between the stabilizing wheel 42 and the track, and such stable contact can reduce the vibration and bumping of the transport device during operation, further ensuring the stability of the mechanism during movement.

[0065] Specifically, a speed reducer 5 is arranged between the driving end of the motor and the driving shaft 33. In this way, the driving gear 31 can be driven to move on the rack 14 by the speed reducer 5, and the gear can be controlled to advance, stop, or retreat on the rack 14.

[0066] It is known that the driving end of the motor is connected to the speed reducer 5, and the speed reducer 5 is connected to the driving shaft 33. When the motor is running, it generates a relatively high speed and a relatively small torque. When the power is transmitted to the speed reducer 5, the gear set (usually including multiple gears of different sizes) or other transmission mechanisms (such as worm gears) inside the speed reducer 5 will change the transmission ratio of the power, achieving the function of speed reduction while the torque increases accordingly. The large torque can ensure the smooth start and stable operation of the transport device.

[0067] Because the speed reducer 5 can increase the torque, it greatly enhances the driving capacity of the transport device. When transporting heavy goods, without the speed reducer 5, the motor may not be able to provide enough torque to drive the transport device to move, or the motor may be overloaded. With the speed reducer 5, even under heavy load, the transport device can be started smoothly and operated normally. For example, when transporting large mechanical parts or raw materials in industrial production, the speed reducer 5 can make the transport device easily cope with heavy loads, expanding the application range of the transport device.

[0068] Moreover, the speed reducer 5 can adjust the transmission ratio as needed, thereby accurately controlling the speed of the transport device. By selecting a speed reducer 5 with different reduction ratios or adjusting the working state of the speed reducer 5, the transport device can be accurately operated at different speeds.

[0069] Specifically, the rack 14 and the monorail 1 are arranged to be equal in length.

[0070] The most important benefit of the equal length arrangement of the rack 14 and the monorail 1 is to ensure the power transmission of the transport device throughout the length of the monorail 1. During long-distance transportation, there is no blank area of power transmission, so that the transport device can move continuously and stably. For some automated transportation systems or long-distance material conveying scenarios, this arrangement can reliably transport goods from one endpoint to another, avoiding the trouble of restarting or adjusting the transport device due to power interruption, and improving transportation efficiency.

[0071] In addition, the equal length arrangement of the rack 14 allows the transport device to better adapt to different transportation distances and transportation tasks. Whether it is short-distance parts transfer or long-distance material conveying, the transport device can effectively function. This arrangement also facilitates the replacement and adjustment of the transport device between monorails 1 of different lengths. For example, when the factory workshop layout is adjusted or the transportation line is optimized, the transport device can easily adapt to the new monorail 1 length, reducing the need for large-scale modification of the transport device structure and reducing equipment update costs.

[0072] The technical means disclosed by the utility model scheme is not limited to the technical means disclosed by the above-mentioned embodiments, but also includes technical solutions composed of any combination of the above technical features. It should be noted that for ordinary skilled persons in the art, without departing from the principles of the utility model, a number of improvements and refinements can be made, and these improvements and refinements are also considered within the scope of protection of the utility model.
