Technical Field

[0001] The utility model relates to a tower crane type logistics vehicle. Background Art

[0002] With the rapid development of e-commerce and supply chain management, the logistics industry has an increasing demand for efficient and intelligent transportation tools. Traditional logistics vehicles are often limited by road conditions and space constraints and are difficult to adapt to complex warehousing and transportation environments. In places such as logistics warehouses and factories, there are often situations where goods are densely stacked and the space is narrow. Traditional forklifts or handcarts have problems of inconvenient operation and low efficiency when handling goods.

[0003] With the continuous progress of automation and intelligent technologies, the application of robots and automated equipment in the logistics field is becoming increasingly widespread. Summary of the Utility Model

[0004] In view of the deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a tower crane type logistics vehicle, which is not only reasonable in structure but also convenient and fast.

[0005] To solve the above technical problem, the technical solution of the utility model is: a tower crane type logistics vehicle, including a frame body. A steering wheel driven by a first servo motor is rotatably connected to the frame body. At least two groups of vertically extending lifting guide columns are fixedly arranged on the steering wheel. Sliders are sleeved and slidably connected outside the lifting guide columns. A support seat is fixedly connected between the sliders. The support seat is vertically penetrated by a lead screw and driven to lift by the lead screw. The bottom of the lead screw is driven to rotate by a stepping motor arranged in the steering wheel. A second servo motor is fixedly arranged on the support seat. A short handle is fixedly connected to the driving end of the second servo motor. A long connecting rod is hinged to the end of the short handle. The other end of the long connecting rod is rotatably connected to a guide rail through a hinge shaft. The guide rail extends horizontally and is slidably connected to a limit slider fixedly arranged at the upper end of the support seat. A claw is arranged at the end of the guide rail.

[0006] Further, the second servo motor, the short handle, the long connecting rod, the guide rail and the limit slider form a crank linkage assembly. Two groups of the crank linkage assemblies are longitudinally symmetrically arranged on the support seat. Both groups of guide rails extend horizontally and the ends are penetrated by the same hinge shaft and connected to the long connecting rods on both sides. The top of the claw is connected between the two guide rails through a fixing plate.

[0007] Further, the lifting guide columns are arranged in a staggered manner with the crank linkage assembly to avoid interference.

[0008] Further, the steering wheel is embedded in the upper part of the frame body and rotatably connected to the frame body through a bearing. An installation groove for installing the stepping motor is recessed at the upper end of the steering wheel.

[0009] Further, a material rack for receiving materials is fixedly provided at the upper end of the frame body, and the material rack is formed by enclosing and fixedly connecting a plurality of enclosing plates.

[0010] Further, rubber wheels for supporting and moving are provided on both sides of the frame body, and the rubber wheels are driven by brushless motors fixedly arranged in the frame body.

[0011] Further, a lidar sensor and a camera are provided at one end of the frame body, and a main control panel is provided at the other end.

[0012] Compared with the prior art, the utility model has the following beneficial effects: Compared with traditional manual handling or forklift handling, the tower crane type logistics trolley can complete tasks more quickly, reducing operation time and costs. The tower crane type logistics trolley is equipped with a variety of sensors, which can achieve intelligent obstacle avoidance and safety monitoring, effectively reducing the accidental risks during the operation process, and can also reduce the potential dangers brought by manual operation during the process of loading and unloading goods. The tower crane type logistics trolley can monitor the surrounding environment in real time through sensors such as lidar and cameras, and can achieve accurate positioning and cargo identification, ensuring the accuracy and reliability of cargo handling. This accuracy can greatly reduce the risks of cargo damage and misoperation. The overall structure is simple, the components cooperate reasonably and stably, and compared with forklift handling, the steering requirement range is smaller, making it more suitable for the situation of dense cargo stacking and narrow space.

[0013] Compared with traditional fuel-driven forklifts, the tower crane type logistics vehicle adopts electric drive, with higher energy utilization efficiency and lower carbon emissions. This conforms to the development trend of energy conservation and environmental protection in the modern logistics industry, and also helps to reduce the operating costs and environmental burden of enterprises.

[0021] As Figures 1 to 4 shown, a tower crane type logistics vehicle includes a vehicle frame main body 1. A steering wheel 3 driven by a first servo 2 is rotatably connected to the vehicle frame main body. Two groups of vertically extending lifting guide posts 4 are fixedly arranged on the steering wheel. Sliders 5 are sleeved and slidably connected outside the lifting guide posts. A support seat 6 is fixedly connected between the two sliders. The support seat is vertically penetrated by a lead screw 7 and connected with a lead screw nut and driven to lift by it. The bottom of the lead screw is driven to rotate by a stepper motor 8 arranged in the steering wheel. A second servo 9 is fixedly arranged on the support seat. A short handle 10 is fixedly connected to the driving end of the second servo. The end of the short handle is hinged with a long connecting rod 11. The other end of the long connecting rod is rotatably connected with a guide rail 26 through a longitudinal hinge shaft 12. The guide rail extends horizontally and is slidably connected with a limit slider 13 fixedly arranged at the upper end of the support seat. After the limit slider and the guide rail are installed, they can only horizontally slide laterally. The guide rail is covered by the limit slider to limit its degrees of freedom except for lateral sliding. A gripper 14 is arranged at the end of the guide rail.

A triangle-like shape is formed by the short handle, the long connecting rod and the guide rail. Two groups of the crank linkage assemblies are longitudinally symmetrically arranged on the support seat. Both groups of guide rails extend horizontally and the ends are connected by the same hinge shaft to the long connecting rods on both sides. The top of the gripper is connected between the two guide rails through a fixing plate 15. The clamping of the gripper and the driving components for driving the gripper to clamp are not generally set, so no more details will be described here.

[0023] In the embodiment of the present utility model, the lifting guide posts are arranged in a dislocation manner with the crank linkage assembly to avoid interference.

The main control panel is electrically connected to the lidar sensor, the camera, the first servo motor, the second servo motor, the battery, and the stepper motor.

[0028] The working principle of the embodiment of the present invention: The rubber wheels drive the logistics vehicle to move forward. After reaching the designated location, the stepper motor drives the lead screw to lower the support base, and the goods are clamped by the clamping jaws and then transferred into the material rack. Among them, the first servo motor controls the rotation of the steering wheel, the second servo motor controls the rotation of the short handle (crank), and drives the guide rail to move horizontally through the long connecting rod, jointly realizing the transfer of goods.
