Description

Technical Field

[0001] This utility model relates to the field of shuttle car positioning, and in particular to a warehouse shuttle car positioning device. Background Technology

[0002] In traditional warehousing and logistics systems, shuttles typically rely on pre-set tracks or ground markings for movement. Their positioning methods often employ mechanical limits, photoelectric sensors, or magnetic navigation technology, which suffer from insufficient flexibility, limited positioning accuracy, or high maintenance costs.

[0003] In existing technologies, shuttles that use independent drive wheels for steering often lack a coordinated control mechanism, resulting in asynchronous steering and track deviation, especially when driving on curves where stability is poor. While track-guided designs can improve path accuracy, they generally suffer from high friction loss, easy derailment, or high requirements for ground flatness.

[0004] To address the aforementioned issues, this patent proposes a warehouse shuttle positioning device that integrates high-precision mechanical guidance, low-friction adaptive steering, and automatic correction functions, thereby solving the problems existing in the prior art and improving the reliability and efficiency of automated warehouse transportation. Utility Model Content

[0005] The main purpose of this invention is to propose a positioning device for warehouse shuttle cars, which aims to solve the problems of inaccurate trajectory control, poor steering stability, and severe track wear of traditional shuttle car positioning devices.

[0006] To address the aforementioned problems, this utility model proposes a positioning device for a warehouse shuttle, comprising a vehicle body, a storage cavity on the upper rear side of the vehicle body, drive wheels rotatably connected to the two front corners of the lower side of the vehicle body, and a positioning and steering assembly between the two drive wheels, movable wheels rotatably connected to the two rear corners of the lower side of the vehicle body, and the two movable wheels connected by a rotating shaft, a positioning track on the lower side of the vehicle body, a positioning groove on the upper end of the positioning track, and the lower end of the positioning and steering assembly inserted into and slidably connected within the positioning groove.

[0007] Preferably, the positioning and steering assembly includes a limit rod, a steering head, a steering control rod, and a positioning slide rod, with the limit rod connected to the front side of the lower end of the vehicle body.

[0008] Preferably, the limiting rod is located between the two drive wheels, and both ends of the limiting rod are rotatably connected to steering heads.

[0009] Preferably, each of the two steering heads is connected to a drive motor at the end away from the limit rod, and the two drive motors are rotatably connected to the drive wheel via rotating shafts.

[0010] Preferably, each of the two drive motors is connected to a bogie at its front end, and a steering control lever is rotatably connected between the two bogies.

[0011] Preferably, a positioning slide rod is connected to the center of the lower end of the steering control rod, and the positioning slide rod is inserted into the positioning slide groove. A positioning rod sleeve is sleeved on the outside of the lower end of the positioning slide rod.

[0012] Preferably, the positioning rod sleeve is slidably connected inside the positioning groove, and an anti-detachment spring is provided inside the lower end of the positioning rod, which is elastically connected to the positioning rod sleeve through the anti-detachment spring.

[0013] Preferably, a descending resistance ball is provided inside the center of the lower end of the positioning rod sleeve, and multiple lateral resistance balls are provided inside the lower side of the outer wall of the cylindrical part of the positioning rod sleeve.

[0014] Beneficial effects:

[0015] 1. This utility model features a storage cavity on the vehicle body to realize the functions of storing and transporting goods. The two front drive wheels and the rear moving wheels work together to ensure smooth movement. Through the cooperation of positioning rails, positioning grooves and positioning steering components, the precise guidance and positioning of the vehicle body's movement trajectory are realized, thereby improving the automation level and operational accuracy of warehousing and transportation.

[0016] 2. The steering control rod of this utility model connects the bogie of the two drive wheels, and achieves steering control through the cooperation of the positioning slide rod and the positioning slide groove. When the positioning slide rod slides along the curved groove, the drive wheels deflect synchronously, ensuring that the steering of the vehicle body is consistent with the direction of the track guidance, avoiding track deviation, and improving steering stability and positioning accuracy.

[0017] 3. When the steering direction of the drive wheel is inconsistent with the guide direction of the track, the positioning rod sleeve and the inner wall of the slide groove continuously push against each other, forcing the drive wheel to adjust to be consistent with the track direction, ensuring that the vehicle body always travels along the predetermined path, avoiding trajectory deviation caused by external interference, and enhancing the reliability of the system.

[0018] 4. The positioning rod sleeve of this utility model is elastically connected to the positioning slide rod through an anti-detachment spring to ensure that it always fits the inner wall of the positioning slide groove and prevents it from detaching; at the same time, it adopts descending resistance ball and side descending resistance ball to reduce sliding friction, which not only ensures smooth movement but also reduces wear and extends the service life of the track and steering components.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] To achieve the above-mentioned utility model objectives, such as Figures 1-4 As shown, this utility model provides a positioning device for a warehouse shuttle, including a vehicle body 1. A storage cavity 2 is provided on the upper rear side of the vehicle body 1. Drive wheels 3 are rotatably connected to the two front corners of the lower end of the vehicle body 1, and a positioning and steering component is provided between the two drive wheels 3. Movable wheels 4 are rotatably connected to the two rear corners of the lower end of the vehicle body 1, and the two movable wheels 4 are connected by a rotating shaft. A positioning track 5 is provided on the lower side of the vehicle body 1. A positioning groove 6 is provided on the upper end of the positioning track 5, and the lower end of the positioning and steering component is inserted into the positioning groove 6 and slidably connected inside the positioning groove 6. The shuttle can store and transport items through the storage cavity 2, and can move on the ground through the two front drive wheels 3 and the two movable wheels 4. It is driven by the two drive wheels 3. The positioning groove 6 on the upper end of the positioning track 5 can guide the movement trajectory of the vehicle body 1 through the positioning and steering component, thereby positioning the movement trajectory of the vehicle body 1. The positioning and steering component can control the steering of the vehicle body 1 according to the movement trajectory.

[0028] Preferably, the positioning and steering assembly includes a limit rod 7, a steering head 8, a steering control rod 11, and a positioning slide rod 12. The limit rod 7 is connected to the lower front side of the vehicle body 1, and the limit rod 7 is located between the two drive wheels 3. The left and right ends of the limit rod 7 are rotatably connected to the steering head 8. The ends of the two steering heads 8 away from the limit rod 7 are each connected to a drive motor 9, and the two drive motors 9 are rotatably connected to the drive wheels 3 through rotating shafts. The front ends of the two drive motors 9 are each connected to a bogie 10, and the steering control rod 11 is rotatably connected between the two bogies 10. The positioning slide rod 12 is connected to the center of the lower end of the steering control rod 11, and the positioning slide rod 12 is inserted into the positioning groove 6. A positioning rod sleeve 13 is sleeved on the outer side of the lower end of the positioning slide rod 12. During the process of guiding the vehicle body 1, the two drive wheels 3 are driven by the drive motors 9 and can deflect simultaneously at the same angle by the left and right movement of the steering control rod 11. This controls the steering of the vehicle body 1. When the positioning slide rod 12 slides in the straight groove of the positioning slide groove 6, the two drive wheels 3 are symmetrically distributed on both sides of the positioning track 5 under the constraint of the steering control rod 11 and the positioning slide rod 12, and move along the straight groove direction. When the positioning slide rod 12 slides in the curved groove of the positioning slide groove 6, the inner wall of the positioning slide groove 6 will push the positioning rod sleeve 13 and drive the positioning slide rod 12 to move in the bending direction. Then, the positioning slide rod 12 drives the steering control rod 11 to move in the bending direction, and drives the drive motor 9 to move in the bending direction through the bogie 10. At this time, since the drive motor 9 is rotatably connected to one end of the limit rod 7 through the steering head 8, and the drive wheel 3 is connected to the drive motor 9 through the shaft, the drive motor 9 will deflect at one end of the limit rod 7 through the steering head 8, and drive the drive wheel 3 to deflect together, thereby realizing the steering of the vehicle body 1.

[0029] During the steering process of the drive wheel 3, when the driving direction of the drive wheel 3 is inconsistent with the guiding direction of the positioning groove 6, the positioning rod sleeve 13 will continuously push against the inner wall of the positioning groove 6 under the drive of the drive wheel 3 until the driving direction of the drive wheel 3 is consistent with the guiding direction of the positioning groove 6, and then stop pushing against the inner wall of the positioning groove 6. This ensures that the drive wheel 3 can always move along the guiding direction of the positioning groove 6, and ensures that the positioning track 5 and the positioning groove 6 accurately position the movement trajectory of the vehicle body 1.

[0030] Preferably, the positioning rod sleeve 13 is slidably connected inside the positioning groove 6. The lower end of the positioning rod 12 is provided with an anti-detachment spring 14, which is elastically connected to the positioning rod sleeve 13. The lower center of the positioning rod sleeve 13 is provided with a descending resistance ball 15, and the lower side of the cylindrical outer wall of the positioning rod sleeve 13 is provided with multiple side-reducing resistance balls 16. During the sliding process of the positioning rod sleeve 13 along the positioning groove 6, the positioning rod sleeve 13 is always in contact with the lower inner wall of the positioning groove 6 under the action of the anti-detachment spring 14, preventing the positioning rod sleeve 13 from detaching from the positioning groove 6 due to uneven ground. At the same time, the positioning rod sleeve 13 can reduce the friction between itself and the inner wall of the positioning groove 6 through the descending resistance ball 15 inside the lower end and the multiple side-reducing resistance balls 16 inside the lower side of the cylindrical outer wall. This allows the positioning rod sleeve 13 to slide smoothly inside the positioning groove 6 and reduces the wear between the positioning groove 6 and the positioning rod sleeve 13.

[0031] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
