Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to a trolley transfer device. Background Technology

[0002] In industrial production and logistics handling scenarios, trolleys are commonly used transportation equipment, and the efficiency and safety of their turning and reversing operations directly affect the overall process. Currently, the conventional method of trolley turning and handling mainly relies on operators manually pushing the trolley to complete the turning and reversing operation. This method has long been the basic operating mode used in the industry.

[0003] However, manual operation has significant drawbacks. First, operators need to continuously apply pushing force to change the direction of the trolley, especially when it is carrying heavy loads. Prolonged operation can significantly increase the labor load and easily lead to operator fatigue. Second, the trolleys are usually quite heavy, making it difficult to precisely control speed and direction during manual pushing. If there is an imbalance in pushing force or slight unevenness in the road surface, the trolley is prone to deviating, colliding, or even tipping over, posing serious safety hazards. Finally, manual alignment relies on the operator's experience and visual judgment, making it difficult to guarantee the accuracy of the trolley's docking with subsequent conveyor belts and workstations. Alignment deviations can cause delays in material loading and unloading, reduce overall work efficiency, and may also increase additional labor costs due to repeated adjustments.

[0004] With the increasing demand for automated production, manual handling can no longer meet the requirements of efficient, safe and precise operations. There is an urgent need for an automated solution that can replace manual labor and does not occupy the original walking space to solve the pain points of existing technology. Summary of the Invention

[0006] To achieve the above objectives, the present invention proposes a trolley transfer device, comprising a transfer mechanism, wherein one end of the transfer mechanism is provided with a fixing seat for positioning, and the other end of the transfer mechanism is provided with a clamping mechanism for clamping and fixing the trolley. The transfer mechanism includes two or more movable units, adjacent movable units are connected by a hinge arm, and the movable unit includes a rotating mechanism and a drive wheel assembly; The two ends of the hinged arm are respectively hinged to the adjacent movable unit. The rotating mechanism is connected to the moving wheel assembly for transmission. The moving wheel assembly is provided with a movable wheel that can roll on a plane. The rotating mechanism is used to drive the moving wheel assembly to rotate around a vertical axis to adjust the rolling direction of the movable wheel.

[0007] In some embodiments of this utility model, the clamping mechanism includes clamping members and clamping cylinders arranged opposite to each other. The clamping cylinders are throttle-connected to the clamping members and are used to drive the clamping members arranged opposite to each other to move closer or further apart.

[0008] In some embodiments of this utility model, the trolley transfer device further includes a limiting mechanism, which is disposed on the articulated arm.

[0009] In some embodiments of this utility model, the limiting mechanism includes an abutment frame and an actuating member. The actuating member is disposed on the hinge arm, and the abutment frame is throttle-connected to the actuating member. The outer contour width of the abutment frame is greater than the contour width of the transfer mechanism.

[0010] In some embodiments of this utility model, the actuating component includes a movable member and an actuating switch, the movable member is connected to the abutting frame, and the movable member abuts against the actuating switch; The movable component is a rotating disk with a slot, and the actuating end of the touch switch is located in the slot.

[0011] In some embodiments of this utility model, the abutment frame includes a protective frame and a connector, one end of the connector is connected to the rotating disk, and the other end of the connector extends outward and is connected to the protective frame.

[0014] In some embodiments of this utility model, the moving wheel assembly includes a connector, and the two ends of the connector are provided with the movable wheels. The connector is connected to the rotating mechanism in a transmission manner.

[0015] In some embodiments of this utility model, a limiting member is provided between the clamping members that are arranged opposite to each other, and the limiting member is used to limit the contact of the trolley.

[0016] This utility model's technical solution uses a fixed base to fix one end of the transfer mechanism, thereby enabling the clamping mechanism at the other end of the transfer mechanism to clamp the trolley and perform transfer activities. Adjacent moving units are connected by hinged arms to form a multi-segment flexible connection structure, which can flexibly adapt to non-linear trajectories such as turns and slope changes during trolley transfer, avoiding deformation and jamming of rigid structures under complex trajectories.

Detailed Implementation

[0020] 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.

If the specific posture changes, the directional indicator will also change accordingly.

[0022] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, the user should consider such a combination of technical solutions to be non-existent and not within the scope of protection claimed by this utility model. See appendix Figure 1-2 This utility model proposes a trolley transfer device, including a transfer mechanism 100. One end of the transfer mechanism 100 is provided with a fixing seat 200 for positioning, and the other end of the transfer mechanism 100 is provided with a clamping mechanism 300 for clamping and fixing the trolley. The transfer mechanism 100 includes two or more movable units 400, adjacent movable units 400 are connected by hinge arms 500, and the movable unit 400 includes a rotating mechanism 410 and a moving wheel assembly 420. The two ends of the hinged arm 500 are respectively hinged to the adjacent movable unit 400. The rotating mechanism 410 is connected to the moving wheel assembly 420 for transmission. The moving wheel assembly 420 is provided with a movable wheel 421, which can roll on a plane. The rotating mechanism 410 is used to drive the moving wheel assembly 420 to rotate around the vertical axis to adjust the rolling direction of the movable wheel 421.

[0023] Based on the above technical features, one end of the transfer mechanism 100 is fixed by the fixed seat 200, thereby realizing the transfer activity of the trolley after the clamping mechanism 300 at the other end of the transfer mechanism 100 clamps it. Adjacent moving units 400 are connected by hinged arms 500 to form a multi-segment flexible connection structure, which can flexibly adapt to non-linear trajectories such as turning and slope changes during trolley transfer, avoiding deformation and jamming of rigid structures under complex trajectories. The rotating mechanism 410 drives the moving wheel assembly 420 to rotate around the vertical axis, which can accurately adjust the rolling direction of the moving wheel 421, so that the transfer mechanism 100 automatically moves along a preset complex trajectory containing arc segments and inclined segments, replacing manual pushing, realizing automated transfer, and greatly reducing the labor intensity of operators.

[0024] The clamping mechanism 300 includes clamping members 310 and clamping cylinders 320 arranged opposite each other. The clamping cylinders 320 are kinetically connected to the clamping members 310 and are used to drive the clamping members 310 to move closer or further apart. The clamping cylinders 320 automatically drive the clamping members 310 to move closer or further apart, realizing automatic clamping and releasing of the trolley. Compared with manual operation, the transfer efficiency is significantly improved. Moreover, the driving force of the clamping cylinders 320 is stable and controllable, ensuring that the trolley is reliably clamped during the transfer process, preventing it from falling off, and greatly improving the safety of the transfer operation.

[0025] Specifically, the trolley transfer device also includes a limiting mechanism 600, which is mounted on the articulated arm 500. The limiting mechanism 600 provides safety protection for the rotation of the articulated arm 500, preventing damage to the articulated arm 500 due to excessive rotation or accidental collision, and ensuring the safe operation of the core transmission components of the transfer mechanism 100.

[0026] Furthermore, the limiting mechanism 600 includes an abutment frame 610 and an actuating member 620. The actuating member 620 is located on the hinge arm 500, and the abutment frame 610 and the actuating member 620 are connected in a transmission manner. The outer contour width of the abutment frame 610 is greater than the contour width of the transfer mechanism 100. Because the outer contour width of the abutment frame 610 is greater than the contour width of the transfer mechanism 100, when the transfer mechanism 100 accidentally collides with an external obstacle, the abutment frame 610 contacts the obstacle first, playing a buffering and blocking role, preventing direct damage to the internal core components such as the hinge arm 500 and the rotating mechanism 410, and effectively protecting the transmission structure of the transfer mechanism 100.

[0027] In this embodiment, the actuating component 620 includes a movable component 621 and an actuating switch 622. The movable component 621 is connected to the abutment frame 610 and abuts against the actuating switch 622. The movable component 621 is a rotating disk with a slot, and the actuating end of the actuating switch 622 is located in the slot. Because the movable component 621 is a rotating disk with a slot, and the actuating end of the actuating switch 622 is located in the slot, when the hinge arm 500 rotates to its limit angle, the rotating disk drives the slot to rotate synchronously, triggering the actuating switch 622. This promptly cuts off the rotational power of the hinge arm 500, preventing damage to the hinge joint due to excessive rotation, and significantly improving the safety and service life of the equipment.

[0028] Furthermore, the abutment frame 610 includes a protective frame and a connector 422. One end of the connector 422 is connected to the rotating disk, and the other end of the connector 422 extends outward and connects to the protective frame. The protective frame of the abutment frame 610 is connected to the rotating disk through the connector 422, and the connector 422 extends outward, making the coverage of the protective frame wider. Both ends of the protective frame extend to positions close to the adjacent movable unit 400, further expanding the protection range and effectively protecting the connection between the articulated arm 500 and the movable unit 400, reducing the impact of external collisions on critical transmission parts, and comprehensively enhancing the equipment's collision resistance and durability.

[0029] In this embodiment, the clamping mechanism 300 further includes a telescopic cylinder 330, and the clamping component 310 includes a clamping frame and a clamping element. The telescopic cylinder 330 is throttle-connected to the clamping element and is used to drive the clamping element to telescopically move within the clamping frame. The clamping air rod is throttle-connected to the clamping frame. The telescopic cylinder 330 drives the clamping element to telescopically move within the clamping frame, allowing the clamping element to be adaptively adjusted according to the size and position of the trolley, greatly expanding the adaptability of the device to trolleys of different specifications and enhancing the versatility of the equipment. The clamping cylinder 320 is throttle-connected to the clamping frame, further improving the accuracy and response speed of the clamping action, and enabling quick and accurate clamping and positioning of the trolley.

[0030] The protective frame extends to both ends near the adjacent movable unit 400, further extending the protective area and providing more comprehensive protection for critical parts susceptible to impact, such as the connection node between the articulated arm 500 and the movable unit 400. This reduces damage to these parts from external impacts and improves the overall structural safety and service life of the equipment.

[0031] Specifically, the moving wheel assembly 420 includes a connector 422, with movable wheels 421 at both ends of the connector 422. The connector 422 is connected to the rotating mechanism 410 via a transmission connection. The presence of movable wheels 421 at both ends of the connector 422 and the transmission connection between the connector 422 and the rotating mechanism 410 ensures that the two movable wheels 421 move synchronously under the drive of the rotating mechanism 410. This makes the movement of the moving unit 400 smoother and the force more balanced, effectively preventing excessive wear or trajectory deviation of the movable wheel 421 on one side due to uneven force distribution, thus improving the stability of the transfer process.

[0032] Furthermore, limiting members 340 are provided between the relatively positioned clamping members 310, and the limiting members 340 are used to limit the contact of the trolley. The limiting members 340 between the relatively positioned clamping members 310 abut against the trolley during the clamping process, accurately limiting the position of the trolley, preventing the trolley from shifting during clamping, ensuring the alignment accuracy of the trolley during the transfer process, facilitating subsequent precise docking with the conveyor belt, workstation, etc., reducing material loading and unloading delays caused by alignment deviations, and improving overall operation efficiency.

[0033] 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.
