Description

Technical Field

[0001] This utility model relates to the field of transportation vehicles, and more specifically, to an automatically lifting rail-guided vehicle. Background Technology

[0002] With the development of modern logistics, automated logistics systems and automated warehouses have emerged, placing higher demands on the efficiency, accuracy, and safety of cargo handling. Rail-guided vehicles have been developed to meet this need, as they can automatically connect with inbound / outbound platforms, conveyors, and other logistics systems to achieve automated material transport and improve warehousing and logistics efficiency.

[0003] In logistics warehousing and manufacturing scenarios, existing rail-guided vehicles can only transport goods across regions. They cannot transport equipment and shelves at different elevations or load and unload goods at different heights, which still requires manual operation by workers, reducing work efficiency. There is also a risk of accidents caused by overturning due to excessive weight of goods. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic lifting rail-guided vehicle with high safety and convenient operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatically lifting rail-guided vehicle, comprising a track, a frame, a traveling mechanism disposed below the frame and driving the frame to move along the length of the track, and a lifting mechanism disposed above the frame. The lifting mechanism includes a lifting platform disposed above the frame, several sets of hydraulic devices disposed between the lifting platform and the frame, the lifting platform being provided with several sets of telescopic forks matching each hydraulic device, and several sets of shape detection components symmetrically disposed on both sides of the lifting platform perpendicular to the track, as well as a controller electrically connected to the shape detection components and the telescopic forks. The shape detection components are used to detect the shape dimensions of the goods to be picked up by the telescopic forks.

[0006] The present invention is further configured such that: the telescopic fork includes a telescopic arm, the telescopic arm is used to reciprocate along the length of the vertical track to transport materials, and the frame is provided with at least one set of anti-tipping components on each of the opposite sides in the direction of movement of the telescopic arm.

[0007] The present invention is further configured such that: the anti-tipping component includes a fixing block, an anti-tipping block and a fastener, the fixing block is fixed to the side of the frame and close to the track, the anti-tipping block is fixed to the fixing block by the fastener, and the anti-tipping block includes a main body fixedly connected to the fixing block and a protrusion connected to the main body.

[0008] The present invention is further configured such that: the shape detection component includes a mounting bracket disposed on the vehicle frame and a vision sensor fixed on the mounting bracket, the mounting bracket having an observation port for facilitating the capture of information by the vision collector, and the observation port having an eave.

[0009] The present invention is further configured such that: the walking mechanism includes a driven wheel disposed at the front end of the frame, a driving wheel disposed at the rear end of the frame, and a drive motor for driving the driving wheel to move.

[0010] The present invention is further configured such that: the telescopic fork includes a first fork body extending laterally, at least one second fork body sleeved on the first fork body, a drive assembly disposed between the first fork body and the second fork body, and a hydraulic motor for driving the first and second forks body, wherein the drive assembly is used to drive the second fork body to extend or retract relative to the first fork body.

[0011] The beneficial effects of this utility model are:

[0012] 1. Rail-guided operation ensures a fixed running path, reducing the chance of collisions with people and other equipment. A stable hydraulic system prevents tipping during lifting and movement. The traveling mechanism works in tandem with the lifting mechanism to quickly move goods to designated locations, reducing manual handling time. The hydraulically driven lifting platform offers smooth and fast lifting, and the telescopic forks provide precise positioning, significantly improving logistics efficiency. The telescopic fork design allows for more flexible loading and unloading, enabling access to confined spaces. In warehouses with compact rack layouts, it can operate flexibly, increasing storage density. Multiple shape detection components combined with a controller can accurately identify the shape and size of goods, and the telescopic forks adjust accordingly, reducing the risk of damage and improving handling accuracy.

[0013] 2. When the telescopic fork arm moves back and forth along the vertical length of the rail to transport materials, it is prone to tipping over due to changes in the center of gravity and external interference. Anti-tipping components are installed on opposite sides of the telescopic arm's movement direction on the chassis. These components provide support and stability to the overall structure from both sides, effectively reducing the possibility of tipping over during material handling and ensuring the stability of the rail-guided vehicle. This allows for safer cargo transport operations. The anti-tipping component's fixing block is fixed to the chassis and close to the rail, providing a stable installation base for the entire anti-tipping structure, allowing it to function better with the chassis's stability. The anti-tipping block is fixed to the fixing block with fasteners, facilitating installation, disassembly, and maintenance. It consists of a main body and a protruding part connected together. This structural design better copes with external forces of different directions and degrees, further enhancing the anti-tipping effect. For example, the protruding part may play a crucial role in blocking and supporting under certain special stress conditions, preventing the vehicle from tilting or becoming unstable.

[0014] 3. The mounting bracket securely fixes the vision sensor to the frame, ensuring it is in the correct position for accurate detection of cargo dimensions. The vision sensor, through the observation port, effectively collects visual information about the cargo, accurately capturing data such as its outline and size. This provides a reliable basis for subsequent precise operation of the telescopic forks. The eaves of the observation port also act as a shield, preventing dust from affecting the normal operation of the vision sensor and avoiding interference from external light. The layout of a front driven wheel and a rear drive wheel, combined with a drive motor driving the drive wheel, allows the frame to move smoothly along the track. The drive wheel provides power to propel the vehicle forward, while the driven wheel provides auxiliary support and following, making the entire movement smoother and more reliable. This ensures the rail-guided vehicle can accurately travel between different work points along a predetermined route, efficiently completing material transport tasks.

[0015] 4. By setting a first fork and a second fork fitted onto the first fork, and with the aid of a drive assembly, the extension or retraction of the second fork relative to the first fork can be achieved. This multi-stage telescopic structure allows the telescopic forks to flexibly adjust their extension length according to the specific location and size of the goods. Whether the goods are close or far away, they can be accurately extended to the appropriate position for picking and handling, greatly improving the adaptability to goods in different stacking situations. The hydraulic motor is used to drive the first and second forks. The hydraulic power has the characteristics of large output force and smooth operation, which can ensure that when picking up heavy goods, the telescopic forks can still stably complete the extension and retraction action without jamming or insufficient power, ensuring the smoothness and reliability of the goods handling process, and providing strong support for the rail-guided vehicle to efficiently complete the material transportation task.

[0019] Reference Figures 1 to 2 The embodiments of this utility model will be further described below.

[0020] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0021] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0022] Figures 1 to 2 The illustrated automatic lifting rail-guided vehicle includes a track 2, a frame 1, a traveling mechanism located below the frame 1 and driving the frame 1 to move along the length of the track 2, and a lifting mechanism located above the frame 1. The track-based operation ensures a fixed running path, reducing the probability of collisions with people and other equipment. A stable hydraulic device 6 prevents tipping during lifting and movement. The traveling mechanism and lifting mechanism work together to quickly transport goods to a designated location, reducing manual handling time. The lifting mechanism includes a lifting platform 3 located above the frame 1 and several sets of hydraulic devices 6 located between the lifting platform 3 and the frame 1. The hydraulically driven lifting platform 3 ensures smooth lifting. Furthermore, it is fast and the telescopic forks 5 can be precisely positioned, greatly improving logistics processing efficiency. The lifting platform 3 is equipped with several sets of telescopic forks 5 that match each hydraulic device 6. The design of the telescopic forks 5 makes picking up and placing goods more flexible and can reach into narrow spaces. In warehouses with compact rack layouts, it can be operated flexibly, increasing storage density. The lifting platform 3 is symmetrically equipped with several sets of shape detection components 4 on both sides perpendicular to the track 2, as well as a controller 7 electrically connected to the shape detection components 4 and the telescopic forks 5. The multiple shape detection components 4 combined with the controller 7 can accurately identify the shape and size of the goods, and the telescopic forks 5 can be precisely adjusted accordingly, reducing the risk of goods damage and improving handling accuracy.

[0023] The telescopic fork 5 includes a telescopic arm, which is used to move back and forth along the length of the vertical rail 2 to transport materials. It is prone to tipping over due to factors such as changes in the center of gravity and external interference. Therefore, the frame 1 is equipped with at least one set of anti-tipping components on each of the opposite sides in the direction of the telescopic arm's movement. This can support and stabilize the overall structure from both sides, effectively reducing the possibility of the vehicle tipping over during material handling, ensuring the stability of the rail-guided vehicle during operation, and enabling it to carry out cargo transportation operations more safely.

[0024] The anti-rollover assembly includes a fixing block 13, an anti-rollover block 15, and a fastener 14. The fixing block 13 is fixed to the frame 1 and to the side near the track 2. The anti-rollover block 15 is fixed to the fixing block 13 by the fastener 14. The anti-rollover block 15 includes a main body 16 fixedly connected to the fixing block 13 and a protrusion 17 interconnected with the main body 16, which facilitates easy installation, disassembly, and maintenance. Furthermore, the structure is composed of the main body 16 and the protrusion 17 interconnected. This structural design can better cope with the influence of external forces from different directions and to different degrees, further enhancing the anti-rollover effect. For example, the protrusion 17 may play a key role in blocking and supporting under certain special stress conditions, preventing the vehicle from tilting or other unstable conditions.

[0025] The shape detection component 4 includes a mounting bracket set on the frame 1 and a vision sensor fixed on the mounting bracket, which can ensure that it is in a proper position to accurately detect the shape and size of the goods. The mounting bracket is provided with an observation port to facilitate the vision collector to capture information. The vision sensor can effectively collect relevant visual information of the goods through the observation port, and achieve accurate capture of data such as the outline and size of the goods, thereby providing a reliable basis for the subsequent precise operation of the telescopic fork 5. In addition, the observation port is provided with an eave to effectively prevent dust from affecting the normal operation of the vision sensor and to avoid interference from external light.

[0026] The traveling mechanism includes a driven wheel 11 located at the front end of the frame 1, a driving wheel 12 located at the rear end of the frame, and a drive motor that drives the driving wheel 12 to move. It enables the frame 1 to move smoothly along the track 2. The driving wheel 12 provides power to drive the vehicle forward, while the driven wheel 11 plays an auxiliary support and following role, making the entire traveling process smoother and more reliable. This ensures that the rail-guided vehicle can accurately travel between different work points along a predetermined route and efficiently complete the material transportation task.

[0027] The telescopic fork 5 includes a first fork 8 extending laterally, at least one second fork 9 sleeved on the first fork 8, a drive assembly disposed between the first fork 8 and the second fork 9, and a hydraulic motor 10 for driving the first and second forks. The drive assembly is used to drive the second fork 9 to extend or retract relative to the first fork 8. This multi-stage telescopic structure allows the telescopic fork 5 to flexibly adjust its extension length according to the specific location and size of the goods. Whether the goods are close or far away, they can be accurately extended to the appropriate position for picking and handling, greatly improving the adaptability to goods in different stacking situations. The hydraulic motor 10 is used to drive the first fork 8 and the second fork 9. Hydraulic power has the characteristics of large output force and smooth operation, which can ensure that when picking up heavy goods, the telescopic fork 5 can still stably complete the extension and retraction action without jamming or insufficient power, ensuring the smoothness and reliability of the goods handling process, and providing strong support for the rail-guided vehicle to efficiently complete the material transportation task.
