Description

Technical Field

[0001] This invention belongs to the field of logistics vehicle technology, and particularly relates to an electric stacking vehicle with a portable auxiliary wheel mechanism and its working method. Background Technology

[0002] Electric stacker trucks are commonly used material handling equipment in the warehousing and logistics industry, mainly used for vertical stacking and horizontal handling of goods.

[0003] To adapt to different working conditions, existing electric aerial stacker trucks are often equipped with auxiliary moving mechanisms. These auxiliary wheel sets are usually installed at the bottom of the forks or under the vehicle body in a fixed or detachable manner. However, in actual working scenarios, especially in old warehouses, outdoor yards, or environments with poor ground conditions, there are often gravel, debris, and other debris on the ground. When the stacker truck is fully loaded or is transporting goods over long distances, these ground obstacles can easily interfere with the equipment's walking mechanism. Furthermore, during the journey, debris on the ground can easily be caught in the gap between the wheels and the mounting brackets, forcing the operation to be interrupted. Summary of the Invention

[0004] To address the problems in the prior art, the present invention proposes the following technical solution: This invention provides an electric stacker truck with a portable auxiliary wheel mechanism, comprising: The vehicle body and forks, wherein an auxiliary moving structure is fitted into one end of the forks near the vehicle body, the auxiliary moving structure includes a pair of fork carriages, and an auxiliary wheel assembly is detachably mounted on the bottom of the fork carriages; the auxiliary wheel assembly includes a fixed seat, and a wheel is rotatably mounted on the inner side of the fixed seat; And a clearing component, the clearing component including a clearing plate, the clearing plate including a contact part and a side blocking part, the contact part being located in front of the wheel's movement path, the side blocking part extending from both ends of the contact part towards both sides of the wheel, the side blocking part and the contact part being integrally enclosed to form a semi-enclosed structure adapted to the wheel, and the contact part being set in an arc shape; As the vehicle moves, the contact part first contacts the obstacle on the travel path to prevent the obstacle from hitting the wheel. At the same time, the arc-shaped surface of the contact part guides the obstacle to the sides. The side barrier part guides the diverted obstacle and blocks debris from the sides from approaching the wheel, causing the debris to leave the rolling area of ​​the wheel.

[0005] As a preferred embodiment of the above technical solution, the obstacle clearing component further includes a mounting block, which is disposed at the end of the side barrier away from the contact portion, and the mounting block and the clearing plate are elastically fitted together along the vehicle travel direction.

[0006] As a preferred embodiment of the above technical solution, the cleaning plate is provided with a T-shaped connecting block at the end near the mounting block, and the mounting block is provided with a corresponding groove for the connecting block to be inserted. Several horizontally extending springs are provided in the groove, and the two ends of the springs are fixedly connected to the connecting block and the top wall of the groove, respectively. In the natural state, the springs provide the cleaning plate with a preload force in the direction of travel. As the vehicle moves, the contact part first contacts the obstacle on the travel path and compresses the spring three for adaptive buffering and yielding.

[0007] As a preferred embodiment of the above technical solution, the auxiliary wheel assembly further includes a latching component, which includes a pair of latching blocks. A spring connecting the two is provided at the end of the latching blocks that are close to each other, and an outwardly extending insertion portion is provided at the end of the latching blocks that are far from each other. The fixed base has symmetrical clearance holes on opposite side plates. The fastener is embedded inside the fixed base, and the plug-in part extends out of the clearance hole in a corresponding manner and remains extended in its natural state. The bottom of the fork is provided with multiple mating grooves, and the auxiliary wheel assembly is assembled in the mating grooves. The protruding insertion part of the auxiliary wheel assembly engages with the corresponding groove on the inner wall of the mating groove.

[0008] As a preferred embodiment of the above technical solution, mounting holes are symmetrically provided on the opposite side plates of the fixing base. The mounting block is provided with a limiting part 1 and a plug-in part 2 in sequence at one end near the fixing base. Multiple limiting parts 2 are elastically provided on the plug-in part 2 at intervals along its circumference. The limiting parts 2 can be embedded into the plug-in part 2 or extend to the outside of the plug-in part 2.

[0009] As a preferred embodiment of the above technical solution, the second insertion part is provided with a plurality of mounting grooves that accommodate the second limiting part along its circumference, and a second spring is provided in the mounting groove to connect the second limiting part with the inner wall of the groove.

[0010] As a preferred embodiment of the above technical solution, it further includes a connecting portion disposed at the end of the fork, and the connecting portion is also provided with an operating portion.

[0011] The operating method of the electric aerial work platform stacker, using any one of the above-described electric aerial work platform stackers with portable auxiliary wheel mechanism, includes the following steps: S1. Assembly Inspection: Ensure that the auxiliary wheel assembly and obstacle removal assembly are stably assembled into the corresponding structures; S2, Vehicle Movement: Control the vehicle to move, the vehicle body drives the forks and auxiliary moving structure to move synchronously, the wheels of the auxiliary wheel assembly roll on the ground as the vehicle body moves, providing auxiliary support and rolling assistance for the vehicle body to move; S3, Obstacle Clearing: The contact part first contacts the obstacle on the travel path to prevent the obstacle from hitting the wheel body. At the same time, the arc-shaped surface of the contact part guides the obstacle to the sides. The side barrier part guides the diverted obstacle and at the same time blocks debris from the sides from approaching the wheel body, so that the debris is removed from the rolling area of ​​the wheel body. S4. Storage and Placement: After completing the material handling or stacking operation, continue to operate the vehicle body to move the auxiliary wheel assembly and obstacle clearing assembly along with the vehicle body to the designated parking position.

[0012] The beneficial effects of this invention are as follows: This invention utilizes a clearing component. During vehicle movement, the contact part first contacts obstacles in the path, preventing them from impacting the wheels. Simultaneously, the arc-shaped surface of the contact part guides and diverts the obstacles to both sides. The side barrier guides the diverted obstacles while preventing debris scattered on both sides from approaching the wheels, thus removing debris from the wheel's rolling area. This achieves both peripheral protection of the wheels, ensuring they are not impacted during movement and preventing shock damage, and effective cleaning and isolation of the wheel's rolling area, preventing debris from entanglement or jamming, maintaining a stable and smooth rolling state, and significantly improving the operational reliability of the auxiliary wheel assembly and the vehicle's driving safety.

[0013] This invention, through the setting of the obstacle clearing component, allows the mounting block and the clearing plate to elastically cooperate along the vehicle's travel direction, enabling the clearing plate to adaptively and elastically retract along the travel direction when encountering obstacles. This effectively buffers impact loads, avoids structural deformation or damage caused by rigid collisions, extends the service life of the obstacle clearing component and the auxiliary wheel component, and provides operators with space to avoid obstacles and further improves the safety and adaptability of the equipment.

[0014] The structural design of this invention is highly compatible with the operational scenarios and material handling requirements of warehousing and logistics, offering multiple advantages: its portable auxiliary mobile structure can be flexibly pulled out and assembled into the forklift's hollow section, adapting to the movement needs of stacker trucks under different working conditions, whether empty or fully loaded. Furthermore, the auxiliary wheel assembly can be quickly disassembled and assembled via snap-fit ​​components, facilitating equipment maintenance and adjustments for different working surfaces. The semi-enclosed obstacle clearing component not only provides outer circumferential protection for the wheels, ensuring they are not impacted during travel and preventing shock damage, but also effectively cleans and isolates the wheel's rolling area, preventing debris from entanglement or jamming, maintaining a stable and smooth rolling state. It also allows the clearing plate to adaptively and elastically retract in the direction of travel when encountering obstacles, improving the equipment's passability and driving safety in complex road conditions. Simultaneously, the obstacle clearing component and the auxiliary wheel assembly employ a plug-in elastic locking structure, making disassembly and assembly convenient and perfectly matching the efficient and flexible operational requirements of stacker trucks.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0017] like Figure 1 , Figure 2 As shown, Figure 1 The diagram shown is an overall schematic of the electric stacker truck in the embodiment. Figure 2 The diagram shown is a partial explosion illustration of the electric stacker truck in the embodiment.

[0018] An electric stacker truck with a portable auxiliary wheel mechanism, the device includes: The vehicle body 1 and the forks 2 mounted on the vehicle body 1 are provided. An auxiliary moving structure 3 is fitted into one end of the forks 2 near the vehicle body 1. The auxiliary moving structure 3 is movably inserted into the mounting frame at the bottom of the vehicle body 1.

[0019] Specifically, the fork 2 has a hollow section at the end near the vehicle body 1. The mounting frame can support and install the auxiliary moving structure 3. Under a certain external force, the auxiliary moving structure 3 can be pulled out or slid into the hollow section of the fork 2. Under normal driving conditions, the auxiliary moving structure 3 can be stably positioned in the hollow section of the fork 2.

[0020] The fork 2 is responsible for lifting and transporting goods. Its hollow section near the end of the vehicle body 1 provides a space for the auxiliary moving structure 3. The mounting frame serves as the track for the sliding of the auxiliary moving structure 3, restricting its movement trajectory. When the fork 2 is in the lowest position, the mounting frame connects with the hollow section of the fork 2, at which point the auxiliary moving structure 3 plays an auxiliary moving role.

[0021] like Figure 3 As shown, Figure 3 The diagram shown is an exploded view of the auxiliary moving structure in the embodiment.

[0022] The auxiliary movement structure 3 includes: a pair of forks 10, with an auxiliary wheel assembly 20 detachably mounted on the bottom of the forks 10.

[0023] The bottom of the fork 10 has multiple mating grooves 11, and the auxiliary wheel assembly 20 is installed in the mating grooves 11.

[0024] It also includes a connecting part 12 provided at the end of the fork 10, and an operating part 13 is also provided on the connecting part 12.

[0025] The two fork carriages 10 are connected by the connecting part 12 at the ends. The width and spacing of the fork carriages 10 are matched with the size of the hollow section on the fork 2. When force is applied to the operating part 13, the fork carriages 10 can be pushed in and pulled out.

[0026] like Figure 4 , Figure 5 As shown, Figure 4 The diagram shown is a schematic of the auxiliary wheel assembly in the embodiment; Figure 5 The diagram shown is an exploded view of the auxiliary wheel assembly in the embodiment.

[0027] The auxiliary wheel assembly 20 includes a fixed base 21, a wheel body 22 is rotatably disposed inside the fixed base 21, the bottom end of the wheel body 22 extends out of the fixed base 21, and clearance holes 211 are symmetrically opened on the opposite side plates of the fixed base 21. The auxiliary wheel assembly 20 also includes a latching member 23, which includes a pair of latching blocks 231. The ends of the latching blocks 231 that are close to each other are provided with a spring 232 connecting the two. The ends of the latching blocks 231 that are far apart from each other are provided with an outwardly extending insertion portion 233. The latching member 23 is embedded inside the fixing base 21, and the insertion portion 233 extends out from the relief hole 211 and remains in the extended state in its natural state.

[0028] The fixed base 21 serves as the mounting frame for the wheel body 22. The wheel body 22 is accommodated on its inner side. The rolling surface of the wheel body 22 is lower than the bottom surface of the fixed base 21, and it contacts the ground and bears the load. When installing the auxiliary wheel assembly 20, by applying external force to the operating part 13, the two forks 10 are pulled out. Then, when the auxiliary wheel assembly 20 is placed into the mating groove 11 of the fork 10, the two protruding plug-in parts 233 will be locked into the corresponding grooves on the inner wall of the mating groove 11, thereby achieving quick installation of the auxiliary wheel assembly 20. After installation, the two forks 10 are pushed into the forks 2. At this time, the wheel body 22 of the auxiliary wheel assembly 20 contacts the ground and bears the load, which facilitates the movement of the vehicle body 1.

[0029] Mounting holes 212 are symmetrically provided on the opposite side plates of the fixing base 21.

[0030] like Figure 6 , Figure 7 , Figure 8 As shown, Figure 6 The diagram shown is a top view of the auxiliary wheel assembly and the obstacle clearing assembly working together. Figure 7 The diagram shown is a schematic of the auxiliary wheel assembly and the obstacle clearing assembly working together (front view). Figure 8 The diagram shown is a top view of the obstacle clearing component in the embodiment.

[0031] It also includes a clearing component, which is detachably mounted on the auxiliary wheel assembly 20.

[0032] The obstacle clearing assembly includes a clearing plate 31, which includes a contact portion 311 and a side barrier portion 312. The contact portion 311 is located in front of the movement path of the wheel body 22, and the side barrier portion 312 extends from both ends of the contact portion 311 towards both sides of the wheel body 22. The side barrier portion 312 and the contact portion 311 are integrally enclosed to form a semi-enclosed structure adapted to the wheel body 22, and the contact portion 311 is set to be arc-shaped. As the vehicle body 1 moves, the contact part 311 first contacts the obstacle on the travel path to prevent the obstacle from hitting the wheel body 22. At the same time, the arc-shaped surface of the contact part 311 guides the obstacle to the sides. The side barrier part 312 guides the diverted obstacle and blocks debris from approaching the wheel body 22, causing the debris to leave the rolling area of ​​the wheel body 22.

[0033] like Figure 6 As shown, arrow A points in the direction of movement. During the movement of the auxiliary wheel assembly 20, the contact portion 311 of the cleaning plate 31 first contacts the obstacle on the path of travel. For example, if the obstacle is... Figure 6 In the stacked state shown, the arc-shaped surface of the contact part 311 can gradually push away and guide the stacked obstacles in the direction indicated by arrow B, so as to avoid the obstacles being squeezed and stuck in front of the wheel body 22.

[0034] The obstacle clearing component also includes a mounting block 32, which is located at the end of the side barrier 312 away from the contact portion 311. The mounting block 32 and the clearing plate 31 are elastically engaged along the vehicle's travel direction.

[0035] like Figure 7 , Figure 10 As shown, Figure 7 The diagram shown is a schematic of the auxiliary wheel assembly and the obstacle clearing assembly working together (front view). Figure 10 The diagram shown is a structural schematic of the obstacle clearing component in the embodiment (front view).

[0036] The cleaning plate 31 is provided with a T-shaped connecting block 313 at the end near the mounting block 32. The mounting block 32 is provided with a groove for the connecting block 313 to be inserted. Several horizontally extending springs 326 are provided in the groove. The two ends of the springs 326 are fixedly connected to the connecting block 313 and the top wall of the groove, respectively. In the natural state, the springs 326 provide the cleaning plate 31 with a preload force in the direction of travel.

[0037] As the vehicle body 1 moves, the contact part 311 first contacts the obstacle on the travel path and compresses the spring 326 to perform adaptive buffering and yielding.

[0038] The cleaning plate 31 and the mounting block 32 form an elastic buffer fit. When the cleaning plate 31 is impacted by an obstacle, it can stably fit the travel path. The impact load is reduced through the elastic buffer effect, avoiding rigid collision between the obstacle clearing component and the auxiliary wheel component 20. This effectively reduces the structural damage of the obstacle clearing component and the obstacle clearing component to the auxiliary wheel component 20 and the obstacle clearing component, and improves the reliability and service life of the structure.

[0039] like Figure 7 As shown, the direction indicated by arrow A is the direction of movement. As the vehicle body 1 moves, the contact part 311 first contacts the obstacle on the travel path and compresses the spring 326 to perform adaptive buffering and yielding. That is, the clearing plate 31 moves in the opposite direction indicated by arrow A, which plays a buffering role and reduces the impact load on the structure of the obstacle clearing component and the auxiliary wheel component 20. When encountering an obstacle that cannot be removed, the clearing plate 31 can avoid the obstacle through elastic buffering, providing the operator with avoidance reaction time and facilitating timely adjustment of the travel route.

[0040] like Figure 5 , Figure 6 As shown, Figure 5 The diagram shown is an exploded view of the auxiliary wheel assembly in the embodiment; Figure 6 The diagram shown is a top-down view of the auxiliary wheel assembly and the obstacle clearing assembly working together.

[0041] Mounting holes 212 are symmetrically provided on opposite side plates of the fixed base 21, and the mounting block 32 is detachably engaged with the mounting holes 212 on the fixed base 21.

[0042] Mounting block 32 enables the cleaning plate 31 to be installed on the fixed base 21.

[0043] like Figure 8 , Figure 9 As shown, Figure 8 The diagram shown is a top view of the obstacle clearing component in the embodiment. Figure 9 What is shown is Figure 8 Enlarged schematic diagram of the structure at point I.

[0044] The mounting block 32 is provided with a limiting part 321 and a plug-in part 322 at one end near the fixed base 21. Multiple limiting parts 323 are elastically provided on the plug-in part 322 at intervals along its circumference. The limiting parts 323 can be embedded into the plug-in part 322 or extend out of the plug-in part 322.

[0045] The second insertion part 322 is provided with a plurality of mounting grooves 324 spaced apart along its circumference to accommodate the second limiting part 323. A spring 325 is provided in the mounting groove 324 to connect the second limiting part 323 and the inner wall of the groove.

[0046] During installation, the limiting part 323 is pressed by external force, and the limiting part 323 retracts into the mounting groove 324 of the insertion part 322. At this time, the insertion part 322 can be smoothly inserted into the corresponding mounting hole 212 of the fixing base 21 to achieve initial positioning. After the insertion part 322 is inserted into the mounting hole 212, the external force is removed. At this time, the limiting part 323 automatically pops out under the action of the spring 325. The limiting part 323 restricts the disengagement of the insertion part 322, thereby achieving the locking installation of the mounting block 32.

[0047] The operating method of the electric aerial work platform stacker, using any one of the above-described electric aerial work platform stackers with portable auxiliary wheel mechanism, includes the following steps: S1. Assembly Inspection: Ensure that the auxiliary wheel assembly and obstacle removal assembly are stably assembled into the corresponding structures; S2, Vehicle movement: Control the vehicle body 1 to move. The vehicle body 1 drives the fork 2 and the auxiliary moving structure 3 to move synchronously. The wheel 22 of the auxiliary wheel assembly 20 rolls on the ground as the vehicle body 1 moves, providing auxiliary support and rolling assistance for the movement of the vehicle body 1. S3, Obstacle Clearing: The contact part 311 first contacts the obstacle on the travel path to prevent the obstacle from hitting the wheel body 22. At the same time, the arc-shaped surface of the contact part 311 guides the obstacle to both sides and diverts it. The side barrier part 312 guides the diverted obstacle and at the same time, the side barrier part 312 blocks the debris scattered on both sides from approaching the wheel body 22, so that the debris is removed from the rolling area of ​​the wheel body 22. S4. Storage and Placement: After completing the material handling or stacking operation, continue to operate the vehicle body 1 to drive the auxiliary wheel assembly 20 and the obstacle clearing assembly to move along with the vehicle body 1 to the designated parking position.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
