Description

Technical Field

[0001] This utility model relates to the field of material conveying equipment technology, specifically to a highly stable long-stroke conveying and loading / unloading system. Background Technology

[0002] When loading and unloading goods into a space with a long distance (such as a train carriage), in order to avoid affecting the loading and unloading of goods, the main body of the loading and unloading system will not be placed in the space where the goods are to be loaded or unloaded. Therefore, the loading and unloading system often needs to have a long extension stroke.

[0003] However, maximizing the long extension stroke of the loading and unloading system while minimizing its size and improving the overall operational stability of the system remains a significant challenge in practice. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a highly stable long-stroke conveying and loading / unloading system, comprising a movable vehicle body and a sliding platform mounted on the vehicle body. A conveyor belt assembly is mounted on the sliding platform. The sliding platform can move relative to the vehicle body along the conveying direction, and can move to the point where a portion of its platform is suspended in the air. The system also includes at least one guide rail connected to the sliding platform and arranged along the conveying direction. A guide wheel assembly is mounted on the vehicle body, capable of abutting at least a portion of the guide rail. The guide wheel assembly includes at least two guide wheels. The guide rail includes a guide edge, and the guide wheels abut against the upper surface of the guide edge and can rotate relative to the guide edge. By moving a portion of the sliding platform to the air, this application allows the sliding platform to move a longer distance away from the vehicle body along the conveying direction, thus enabling the loading / unloading system to have a longer conveying stroke without increasing the overall size of the system. Meanwhile, by placing the guide wheel of this application on the upper part and abutting against the upper surface of the guide edge, the cooperation between the guide wheel and the guide edge can limit the sliding platform and prevent the sliding platform from tipping over. This tendency to tip over is more serious when the sliding platform moves outward to a suspended state. Therefore, by setting the guide wheel to limit and press against the guide edge located on the sliding platform, this application can enable the loading and unloading system to have high conveying stability while ensuring a long conveying stroke.

[0005] Furthermore, the guide rails are in two sets, respectively disposed on both sides of the sliding platform. Corresponding to the guide rails, two sets of guide wheels are also provided, with at least one guide wheel located at each end near the sliding platform. This ensures a more balanced guiding and limiting force on the sliding platform. Simultaneously, the guide wheels on both sides of the sliding platform also limit its position perpendicular to the conveying direction, maintaining the platform in a centered position and ensuring the operational stability of the loading and unloading system. The presence of at least one guide wheel at each end near the sliding platform ensures that even when the platform is suspended, the guide wheel still provides limiting and stopping functions.

[0006] Furthermore, at least two load-bearing wheels are provided on the upper surface of the vehicle body to support the sliding platform. The axial direction of the load-bearing wheels is perpendicular to the conveying direction, and the arrangement of the load-bearing wheels is along the conveying direction. Therefore, this application places the load-bearing wheels below the sliding platform and cooperates with the guide wheels. The load-bearing wheels play a role in load-bearing and guiding, while the guide wheels play a role in limiting movement, which also improves the durability of the loading and unloading system.

[0007] Furthermore, the load-bearing wheel is located on the lower side of the guide rail and abuts against the guide rail.

[0008] Furthermore, a limiting flange is provided on the side of the load-bearing wheel away from the guide wheel, and the outer diameter of the limiting flange is larger than the outer diameter of the main wheel body of the load-bearing wheel. Therefore, the limiting flange of the load-bearing wheel is located on the side opposite to the guide wheel, thus limiting one side of the guide rail by the guide wheel and the other side by the limiting flange of the load-bearing wheel, thereby ensuring that the sliding platform is centered and will not experience significant swaying during transport.

[0009] Furthermore, the guide edge is located above the vehicle body, and the guide wheel is mounted on the upper surface of the vehicle body via a mounting plate. One end of the mounting plate is connected to the upper surface of the vehicle body, and the other end extends away from the upper surface of the vehicle body. Therefore, by positioning the guide edge above the vehicle body, clearance space is provided for mounting the guide wheel, facilitating its installation on the vehicle body.

[0010] Furthermore, the system also includes at least one drive chain for moving the sliding platform along the conveying direction, with a connecting seat for connecting the drive chain located on the bottom side of the sliding platform. When the drive chain moves, it drives the sliding platform to move. Simultaneously, in conjunction with the guide wheels and load-bearing wheels, the loading and unloading process of the system is highly stable, and the service life of each component is extended.

[0011] Furthermore, the conveyor belt assembly includes a central conveyor belt assembly connected to the sliding platform, and end conveyor belt assemblies located near the two ends of the central conveyor belt assembly. A transition conveyor belt assembly is also provided between the central conveyor belt assembly and at least one of the end conveyor belt assemblies. The end conveyor belt assembly and the transition conveyor belt assembly are rotatable relative to the sliding platform.

[0012] Furthermore, it also includes a slewing support and a slewing platform connected to the slewing support, the end conveyor belt assembly and the transition conveyor belt assembly being connected to the slewing platform, and a connecting plate extending toward a direction away from the slewing platform and the transition conveyor belt assembly being provided on the slewing platform, the end conveyor belt assembly being connected to the upper edge of the connecting plate.

[0013] Furthermore, it also includes a lifting drive source connected to the end conveyor belt assembly, the lifting drive source being hinged to the rotary platform. Attached Figure Description

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0017] See appendix Figure 1 and 2 As shown, this application provides a highly stable long-stroke conveying and loading / unloading system for loading and unloading goods in a space with a long distance (e.g., a train carriage). It includes a vehicle body 1 and a sliding platform 2 mounted on the vehicle body 1. A conveyor belt assembly is mounted on the sliding platform 2, which can move relative to the vehicle body 1 along the conveying direction. Figure 1 The direction of the middle arrow A is the direction of the movement along the straight line. Therefore, through the conveyor belt assembly, goods can be smoothly transported over a relatively long distance to the outside world without the loading / unloading system entering the cargo loading space.

[0018] The vehicle body 1 in this application is a movable vehicle body 1, for example, it can be moved by having wheels 11 installed at its bottom. Therefore, the loading and unloading system can be moved to the target location via the vehicle body 1.

[0019] The sliding platform 2 of this application can be moved to the point that part of its platform is suspended in the air. It also includes at least one guide rail 3 connected to the sliding platform 2 and arranged along the conveying direction. A guide wheel assembly is provided on the vehicle body 1 that can abut against at least a part of the guide rail 3. The guide wheel assembly includes at least two guide wheels 4. The guide rail 3 includes a guide edge 31. The guide wheels 4 abut against the upper surface of the guide edge 31 and can rotate relative to the guide edge 31.

[0020] The "suspending part of the sliding platform 2" in this application means that after the sliding platform 2 moves a certain distance away from the vehicle body 1 along the conveying direction of the loading and unloading system, the end of the sliding platform 2 away from the vehicle body 1 is no longer connected to the vehicle body 1, but is suspended in the air. This allows the sliding platform 2 to move a longer distance away from the vehicle body 1 along the conveying direction, thereby enabling the loading and unloading system to have a longer conveying stroke. Simultaneously, by placing the guide wheel 4 on top and abutting against the upper surface of the guide edge 31, the guide wheel 4 and the guide edge 31 (attached)... Figure 3 and Figure 4The cooperation of the guide wheel 4 can limit the sliding platform 2 and prevent it from tipping over. This tendency to tip over is more serious when the sliding platform 2 moves outward to a suspended state. Therefore, this application limits and presses the guide edge 31 located on the sliding platform 2 by setting the guide wheel 4. This allows the loading and unloading system to have high conveying stability while ensuring a long conveying stroke, but without increasing the overall size of the loading and unloading system.

[0021] In some embodiments, the guide edge 31 of this application is located on the outer wall of the guide rail 3, and the upper edge of the guide rail 3 is higher than the guide edge 31. For example, the cross-section of the guide edge 31 and the guide rail 3 is approximately "T" shaped. Therefore, it is convenient to cooperate between the guide edge 31 and the guide wheel 4, and the structure of the guide rail 3 that requires the guide edge 31 is also simplified.

[0022] In some implementations, see Appendix Figure 5-6 As shown, the loading system of this application also includes a skid drive system for moving the skid platform 2. The skid drive system includes a drive motor 41, a transmission chain 42 for moving the skid platform 2 along the conveying direction, and transmission gears 43. The transmission gears 43 are respectively located at the front end and rear end of the vehicle body 1. The transmission chain 42 meshes with the transmission gears 43 located at the front end and rear end, respectively. A connecting seat 44 is provided on the bottom side of the skid platform 2 (see Appendix). Figure 6 The transmission chain 42 is connected to the two ends of the connecting seat 44, and the sliding platform 2 is moved when the transmission chain 42 moves. For example, the connection between the transmission chain 42 and the connecting seat 44 can be achieved by setting a connecting post 441 (or connecting bolt) near the beginning and end of the transmission chain 42 on the connecting seat 44, and connecting the beginning and end of the transmission chain 42 to the ends of the two connecting posts 411. This application sets the power transmission system of the sliding platform 2 independently and uses the transmission chain 42 to ensure a smooth conveying process. At the same time, with the help of the guide wheel 4 and the load-bearing wheel 5, the loading and unloading process of the loading and unloading system is highly stable and the service life of each component is longer.

[0023] In some embodiments, the drive motor 41 is located below the top surface of the vehicle body 1, and two transmission chains 42 are symmetrically arranged below the sliding platform 2. The transmission shaft 45 is coaxially connected to the transmission gears 43 of the two sets of transmission chains 42, and the sprockets and chains driven by the drive motor 41 are arranged on the transmission shaft 45. Therefore, the two transmission chains 42 can be transmitted under the action of the drive motor 41.

[0024] In some embodiments, the length of movement of the sliding platform 2 relative to the vehicle body 1 can be controlled by the number of revolutions of the drive motor 41, or by setting a sensor on the vehicle body 1 at a position where the sliding platform 2 is allowed to move to sense the position of the sliding platform 2. When the sliding platform 2 moves to the sensor, the drive motor 41 stops rotating, thereby achieving the effect of controlling the movement distance of the sliding platform 2.

[0025] In some implementations, the length of the vehicle body 1 is greater than the length of the sliding platform 2, thus ensuring that the loading and unloading system can still maintain a stable center of gravity when the vehicle body 1 moves the sliding platform 2 to a state where its platform part is suspended in the air.

[0026] In some embodiments, the guide rails 3 are in two sets, respectively disposed on both sides of the sliding platform 2. Corresponding to the guide rails 3, two sets of guide wheels 4 are provided, with at least one guide wheel 4 located at each end near the sliding platform 2 (i.e., the end of the sliding platform 2 along the front-rear direction of the conveying direction). This makes the guiding force and limiting force on the sliding platform 2 more balanced. Simultaneously, the guide wheels 4 located on both sides of the sliding platform 2 can also limit the sliding platform 2 perpendicular to the conveying direction, keeping the sliding platform 2 in a centered position and ensuring the operational stability of the loading and unloading system. The presence of at least one guide wheel 4 near the end of the sliding platform 2 ensures that even when the sliding platform 2 is in a suspended position, the guide wheel 4 can still limit and stop the sliding platform 2.

[0027] In some embodiments, at least two load-bearing wheels 5 are also provided on the upper surface of the vehicle body 1 to support the sliding platform 2, and the axial direction of the load-bearing wheels 5 is perpendicular to the conveying direction. In some embodiments, there are multiple load-bearing wheels 5, and they are arranged along the conveying direction (…). Figure 1 The load-bearing wheels (in the direction of the middle arrow A) are arranged sequentially. Therefore, in this application, the load-bearing wheels 5 are placed below the sliding platform 2 and cooperate with the guide wheels 4. The load-bearing wheels 5 play a load-bearing role, and the guide wheels 4 play a limiting role, which also improves the durability of the loading and unloading system.

[0028] In some embodiments, the load-bearing wheel 5 is disposed on the lower side of the guide rail 3 and abuts against the guide rail 3.

[0029] In some embodiments, a limiting flange 51 is provided on the side of the load-bearing wheel 5 away from the guide wheel 4, and the outer diameter of the limiting flange 51 is larger than the outer diameter of the main wheel body of the load-bearing wheel 5. Therefore, the limiting flange 51 of the load-bearing wheel 5 is located on the side opposite to the guide wheel 4, so that one side of the guide rail 3 is limited by the guide wheel 4 and the other side is limited by the limiting flange 51 of the load-bearing wheel 5, thereby keeping the sliding platform 2 in a centered position and preventing significant shaking during transport.

[0030] In some embodiments, the guide edge 31 is located above the vehicle body 1, and the guide wheel 4 is mounted on the upper surface of the vehicle body 1 via a mounting plate 6. One end of the mounting plate 6 is connected to the upper surface of the vehicle body 1, and the other end extends away from the upper surface of the vehicle body 1. Therefore, by positioning the guide edge 31 above the vehicle body 1, clearance space can be provided for mounting the guide wheel 4, making it convenient to mount the guide wheel 4 onto the vehicle body 1.

[0031] In some embodiments, the conveyor belt assembly includes a central conveyor belt assembly 71 connected to the sliding platform 2, and end conveyor belt assemblies 72 located near the two ends of the central conveyor belt assembly 71.

[0032] In some embodiments, the end conveyor belt assembly 72 includes an end conveyor belt assembly 721 at the input end and an end conveyor belt assembly 722 at the output end. The middle conveyor belt assembly 71 is configured with one end higher than the other, with the lower end located below the end conveyor belt assembly 721, and a transition conveyor belt assembly 73 located below the higher end. This staggered arrangement of the two end conveyor belt assemblies 72 and the middle conveyor belt assembly 71 ensures smooth transport of goods. Generally, goods are transported along... Figure 1 The direction of the middle arrow A is used for conveying. When it is necessary to convey the goods in the opposite direction, the conveying and unloading system of the present invention can be rotated 180 degrees.

[0033] Both end conveyor belt assemblies 72 and the transition conveyor belt assembly 73 can rotate relative to the sliding platform 2. By setting the transition conveyor belt assembly 73 and adopting a configuration where one end of the middle conveyor belt assembly 71 is higher than the other, this application enables a better connection between the end conveyor belt assemblies 72 and the middle conveyor belt assembly 71 when the loading and unloading system needs to rotate, thus ensuring that the goods are transported smoothly.

[0034] In some embodiments, the rotation of the end conveyor belt assembly 72 and the transition conveyor belt assembly 73 is achieved by providing a slewing support 81. The slewing support 81 is mounted on the sliding platform 2, and a slewing platform 82 is mounted on its upper side. The end conveyor belt assembly 72 is connected to the slewing platform 82. A connecting plate 83 is provided on the slewing platform 82, extending away from the slewing platform 82 and the transition conveyor belt assembly 73. The end conveyor belt assembly 72 is connected to the upper edge of the connecting plate 83. Therefore, by setting the connecting plate 83 to extend away from the transition conveyor belt assembly 73, it is ensured that both the end conveyor belt assembly 72 and the transition conveyor belt assembly 73 are simultaneously connected to the slewing platform 82 without interfering with each other.

[0035] In some embodiments, a lifting drive source 9 connected to the end conveyor belt assembly 72 is also included, and the lifting drive source 9 is hinged to the rotary platform 82. In some embodiments, a connecting frame is provided on the bottom side of the end conveyor belt assembly 72 for connecting to the end of the push rod of the lifting drive source 9, and the push rod of the lifting drive source 9 is hinged to the connecting frame. Therefore, under the action of the lifting drive source 9, the end conveyor belt assembly 72 can be tilted at a certain angle to facilitate the picking and dropping of goods at different heights.

[0036] In some embodiments, the outrigger assembly includes a support foot 101, a lifting cylinder 102, and a telescopic arm 103. When the outrigger assembly is needed to provide support, the lifting cylinder 102 pushes the support foot 101 downwards to the ground. When the outrigger is not needed, the telescopic arm 103 can be retracted, thereby retracting the outrigger assembly into the vehicle body 1.

[0037] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
