Description

Technical Field

[0001] This utility model relates to the field of transport trolley technology, specifically a trolley with a clamping mechanism. Background Technology

[0002] A trolley, also known as a cargo trolley or cage trolley, is a unit mobile container equipment equipped with four casters for transporting and storing materials. It is commonly used in logistics distribution or logistics turnover between factory processes.

[0003] Existing trolleys have a flat top structure, allowing goods to be placed on the roof during transport. However, the top of the trolley lacks a limiting structure, which can cause goods to fall off if they are not stacked neatly during vehicle movement. Therefore, we propose a trolley with a clamping mechanism. Utility Model Content

[0004] To address the shortcomings of existing trolleys that lack a limiting mechanism at the top, this utility model provides a trolley with a clamping mechanism. It features a clamping plate at the top edge of the trolley, which can clamp and limit the goods when the clamping plate is in a vertical state, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a trolley with a clamping mechanism, including a trolley body, a load-bearing frame on the top of the trolley body, the bottom of the load-bearing frame being connected to the top of the trolley body via multiple mounting seats, and a placement plate being mounted on the top of the load-bearing frame;

[0007] Clamping plates are provided on the top four sides of the placement plate. The bottom of the clamping plates is rotatably connected to the edge of the support frame, and the bottom center of each clamping plate is rotatably connected to one end of the telescopic mechanism through an arc-shaped support arm.

[0008] The telescopic mechanism is located below the load-bearing frame, and the other end of the telescopic mechanism is rotatably mounted on the bottom of the load-bearing frame. When the telescopic mechanism extends, it pushes the clamping plate to the side of the placement plate. When the telescopic mechanism retracts, the clamping plate is flipped to the underside of the edge of the placement plate.

[0009] Preferably, the clamping plate includes a first strip rod disposed on the side of the placement plate, the top of the first strip rod being vertically connected to multiple railings, and the bottom of the railings being connected to a second strip rod;

[0010] The bottom of the first bar is connected with multiple L-shaped arms at intervals, and the other end of the L-shaped arms is rotatably connected to the bottom of the load-bearing frame.

[0011] The middle part of the first bar is connected to one end of the arc-shaped support arm, and the other end of the arc-shaped support arm extends to the bottom of the load-bearing frame.

[0012] Preferably, the load-bearing frame has a reinforcing frame inside, and multiple outwardly extending frame members are connected to the edge of the load-bearing frame;

[0013] The bottom of the L-shaped support arm is rotatably installed below the frame, and the end of the telescopic mechanism away from the arc-shaped support arm is rotatably installed below the reinforcing frame.

[0014] Preferably, the vehicle body includes a frame, and the mounting seat is disposed on the top of the frame;

[0015] Supports are installed at both ends of the frame, and a support shaft extending out of the frame is rotatably installed inside each support. A wheel is installed at the end of each support shaft, and the end of the support shaft away from the wheel is connected to the drive motor. The drive motor is located on the side of the end of the frame.

[0016] The chassis is equipped with a rechargeable battery pack, which is electrically connected to the controller. The controller is electrically connected to the four drive motors and the telescopic mechanism.

[0017] Preferably, a control cabinet is provided on the side of the chassis, and the controller is installed inside the control cabinet;

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Please see Figures 1 to 5 The present invention provides a technical solution: a trolley with a clamping mechanism, including a trolley body, a bearing frame 15 on the top of the trolley body, the bottom of the bearing frame 15 being connected to the top of the trolley body by a plurality of mounting seats 14, specifically mounting seats 14 being provided at the four corners of the bearing frame 15, and a placement plate 9 being installed on the top of the bearing frame 15, the placement plate 9 being a rectangular plate, and the placement plate 9 being detachably connected to the bearing frame 15, that is, the two being fastened by bolts;

[0030] like Figure 1 As shown, clamping plates are provided on the four sides of the top of the placement plate 9. Each clamping plate includes a first strip rod 6 provided on the side of the placement plate 9. Multiple railings 7 are vertically connected to the top of the first strip rod 6, and the bottom of the railings 7 is connected to the second strip rod 8.

[0031] The bottom of the first strip rod 6 is connected with multiple L-shaped support arms 5 at intervals. The other end of the L-shaped support arm 5 is rotatably connected to the bottom of the support frame 15. The middle part of the first strip rod 6 is connected to one end of the arc-shaped support arm 2. The other end of the arc-shaped support arm 2 extends to the bottom of the support frame 15. The end of each arc-shaped support arm 2 away from the first strip rod 6 is rotatably connected to one end of the telescopic mechanism 13. The telescopic mechanism 13 is located below the support frame 15, and the other end of the telescopic mechanism 13 is rotatably installed below the support frame 15. The telescopic mechanism 13 can be a cylinder, a hydraulic cylinder, or an electric telescopic rod. Here, an electric telescopic rod or a hydraulic cylinder is preferred.

[0032] The specific operation process is as follows: Figure 5During telescopic movement, when the telescopic mechanism 13 extends, it pushes the clamping plate to the side of the placement plate 9. At this time, the L-shaped support arm 5 is also positioned on the side of the placement plate 9. The four clamping plates simultaneously surround the edge of the placement plate, allowing the object within to be clamped and limited, preventing it from falling during transportation.

[0033] like Figure 4 During the telescopic process, when the telescopic mechanism 13 is shortened, the clamping plate is flipped to below the edge of the placement plate 9. It should be noted that when the clamping plate is flipped to below the placement plate 9, the edge of the clamping plate (i.e., the second strip 8) is located below the placement plate 9, minimizing contact between the second strip 8 and the human body. Then, the operator can place the goods on the placement plate. After stacking, the telescopic mechanism can drive the clamping plate to clamp the goods, preventing them from falling.

[0034] Furthermore, the load-bearing frame 15 has been improved by incorporating a reinforcing frame 16 inside the load-bearing frame 15. Multiple outwardly extending frame bodies 17 are connected to the edges of the load-bearing frame 15. This design not only maintains a certain level of support rigidity but also increases the support area. The bottom of the L-shaped support arm 5 is rotatably mounted below the frame body 17, and the end of the telescopic mechanism 13 furthest from the arc-shaped support arm 2 is rotatably positioned below the reinforcing frame 16.

[0035] Furthermore, the vehicle body includes a frame 1, and mounting seats 14 are disposed on the top of the frame 1 and at the four corners of the top of the frame;

[0036] like Figure 1 As shown, supports 10 are installed at both ends of the frame 1. Support shafts 3 extending out of the frame 1 are rotatably installed inside the supports 10. Wheels 4 are installed at the ends of the support shafts 3. The end of the support shaft 3 away from the wheel is connected to the drive motor 11. The drive motor 11 is located on the side of the end of the frame 1. The drive motor 11 is connected to the support shaft 3 through a gearbox, which can increase the output torque of the drive motor.

[0037] A control cabinet 12 is provided on the side of the frame 1. The controller is installed in the control cabinet 12. A rechargeable battery pack is provided inside the frame 1. The rechargeable battery pack is electrically connected to the controller. The controller is electrically connected to four drive motors 11 and telescopic mechanism 13 respectively. An obstacle avoidance sensor and an alarm are provided on the side of the frame 1. The obstacle avoidance sensor and the alarm are electrically connected to the controller respectively. The obstacle avoidance sensor is an infrared detector, an ultrasonic detector, etc., and the alarm is an alarm horn.

[0038] To better control the vehicle body, the control cabinet 12 or the vehicle frame is equipped with a locator that is electrically connected to the controller. The control cabinet 12 is also electrically connected to a wireless transceiver. All of the above electrical connections are made through wires and signal lines to realize the transmission of electrical energy and signals.

[0039] Based on the above embodiments, further optimization is possible. The vehicle body can turn around on the spot or turn at any angle. Wheel 4 is a McCann wheel, which is convenient for turning around. That is, the four drive motors can drive the wheels simultaneously, or the wheels can be controlled separately. The driving force of each wheel can be controlled independently, thereby achieving precise driving force distribution. In this way, the operation of turning around on the spot can be easily completed.

[0040] Based on the above embodiments, further optimization is possible. Wheel 4 can be replaced with a track wheel, which would allow the vehicle to travel on a track.
