Description

Technical Field

[0001] This utility model relates to the field of logistics and transportation technology, and in particular to an automatic loading and unloading device for cargo strapping on a logistics flatbed truck. Background Technology

[0002] Currently, large flatbed trucks are frequently used in the logistics industry to improve freight efficiency. To prevent goods from falling off during transport, a single strapping band, 400-600 meters long, is often used to secure the goods stacked on the flatbed truck. Due to the excessive length of the strapping band, its retrieval is difficult, requiring numerous loading and unloading workers to disassemble and store it simultaneously. The entire process is time-consuming and labor-intensive. Furthermore, workers are prone to tangling the strapping bands during retrieval and sorting. Once tangled, the strapping bands are difficult to untangle, necessitating cutting the knotted portion, which damages the strapping band and makes subsequent securing of goods even more difficult. Summary of the Invention

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing an automatic loading and unloading device for cargo strapping on logistics flatbed trucks.

[0004] To achieve the above objectives, the present invention can adopt the following technical solution:

[0005] The automatic loading and unloading device for cargo strapping on a logistics flatbed truck according to this utility model includes a mounting frame fixed to the bottom surface of the logistics flatbed truck body, and a winch mechanism and a power source mounted on the mounting frame. The winch mechanism consists of a rotating shaft mounted horizontally on the mounting frame for winding the cargo strapping, and a pair of limiting plates spaced apart on the rotating shaft. One end of the rotating shaft is connected to a manual rotating handle for manually operating its rotation. The power output end of the power source is connected to a power transmission pair consisting of a driving wheel, a driven wheel, and a transmission belt. The driven wheel of the power transmission pair is connected to the rotating shaft via a manual clutch with an operating handle.

[0006] Furthermore, the power source is a permanent magnet DC motor.

[0007] Furthermore, a guide rod is installed on the mounting frame above the winch mechanism. The cargo strapping passes through the guide rod and is fixed to the rotating shaft of the winch mechanism. When the winch mechanism is driven by the power source to rotate and retract or release the cargo strapping, the guide rod will start synchronously, driving the cargo strapping to reciprocate and move horizontally. Thus, when the winch mechanism retracts or releases the cargo strapping, the guide rod can drive the cargo strapping to reciprocate and move horizontally at the same time, ensuring that the cargo strapping can be evenly distributed on the rotating shaft of the winch mechanism during the winding process, and ensuring that the cargo strapping can be neatly stored.

[0008] Furthermore, in order to effectively prevent dust, a dustproof plate is provided on the mounting frame located on one side of the winch mechanism, and a dustproof cover that covers the winch mechanism is hinged to the lower edge of the dustproof plate.

[0009] Furthermore, in order to reduce weight, weight-reducing holes are provided on the limiting stop plate.

[0010] The advantages of this utility model are that it can be easily installed on the bottom surface of a logistics flatbed truck using a mounting bracket. This allows for easy loading and unloading of cargo strapping using a power source and winch mechanism when bundling or unbundling goods. It enables automated storage of cargo strapping up to 400-600 meters long, reducing the difficulty and time required for storage, minimizing labor and labor intensity. It also effectively prevents the cargo strapping from knotting when winding or unwinding, avoids cutting the strapping, and ensures its long-term usability. Attached Figure Description

[0013] 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.

[0014] like Figure 1 , 2 As shown, the automatic loading and unloading device for cargo strapping on a logistics flatbed truck according to this utility model includes a mounting frame 1. The mounting frame 1 can be easily installed on the bottom surface of the logistics flatbed truck body by means of bolt assembly, or it can be directly fixed to the bottom surface of the logistics flatbed truck body by welding. A winch mechanism 2 and a power source 3 are provided on the mounting frame 1.

[0015] Specifically, the winch mechanism 2 consists of a rotating shaft 2.1 mounted horizontally on the mounting frame 1, and a pair of limiting plates 2.2 spaced apart on the rotating shaft 2.1. The two limiting plates 2.2 are fixedly fitted onto the rotating shaft 2.1, forming a storage section for winding cargo strapping between the two limiting plates 2.2. A bearing seat 4 is fitted onto the rotating shaft 2.1 located outside the two limiting plates 2.2, thereby fixing the entire winch mechanism 2 to the mounting frame 1 through the bearing seats 4. This ensures that the rotating shaft 2.1 is mounted horizontally on the mounting frame 1 while also ensuring that it can rotate along the axis, thus easily winding and storing cargo strapping on the rotating shaft 2.1 between the two limiting plates 2.2.

[0016] Power source 3 preferably uses a permanent magnet DC motor, specifically the ZD101AZ1-250W24V model manufactured by Zhejiang Unite Motor Co., Ltd., which is readily available on the market. A power transmission pair 5 is connected to the power output end of power source 3. This power transmission pair 5 consists of a driving wheel 5.1, a driven wheel 5.2, and a transmission belt 5.3. The driving wheel 5.1 is coaxially fixed to the power output shaft of power source 3, while the driven wheel 5.2 is coaxially mounted on the rotating shaft 2.1. The driven wheel 5.2 is connected to the rotating shaft 2.1 via a manual clutch 6 mounted on the rotating shaft 2.1. The manual clutch 6 has an operating handle 7, which allows the driven wheel 5.2 to be connected or disconnected from the rotating shaft 2.1 by moving the operating handle 7, thus easily enabling the power source 3 to drive the rotating shaft 2.1 to rotate automatically.

[0017] In addition, to enable manual rotation of the winch mechanism 2, a rotating rod 8 perpendicular to its axis can be connected to one end of the rotating shaft 2.1, and a rotating handle 9 can be provided at the end of the rotating rod 8 away from the rotating shaft 2.1. This allows for easy control of the rotating shaft 2.1 to rotate along its axis by rotating the handle 9, facilitating manual operation of the rotating shaft 2.1. To further reduce effort during manual operation, multiple weight-reducing holes 10 can be evenly spaced along the circumference of the limiting plate 2.2, thereby significantly reducing the weight of the limiting plate 2.2.

[0018] Furthermore, a smooth rod cable guide 11 can be installed on the mounting frame 1 above the winch mechanism 2. The smooth rod cable guide 11 can be a GP3-20A precision cable guide manufactured by Shanxi Tianxiang Machinery Co., Ltd. When the winch mechanism 2 is driven by the power source 3 to rotate and retract the cargo strapping, the smooth rod cable guide 11 will start synchronously, driving the cargo strapping to reciprocate horizontally. Thus, when the winch mechanism 2 retracts and retracts the cargo strapping, the smooth rod cable guide 11 can drive the cargo strapping to reciprocate horizontally at the same time, ensuring that the cargo strapping can be evenly distributed on the rotating shaft 2.1 of the winch mechanism 2 during the winding process, ensuring that the cargo strapping is neatly stored.

[0019] Furthermore, since the entire device is installed on the underside of the logistics flatbed truck and travels with it, in order to effectively prevent dust, a dustproof plate 12 can be installed on the mounting bracket 1 located on one side of the winch mechanism 2, and a dustproof cover 13 that can cover the winch mechanism 2 can be hinged to the lower edge of the dustproof plate 12. When the dustproof cover 13 is rotated upward to cover the winch mechanism 2, the other edge of the dustproof cover 13 away from the hinge side can be locked to the body of the logistics flatbed truck by a latch, thereby locking the rotation position of the dustproof cover 13, so that the dustproof cover 13 can protect the winch mechanism 2 and prevent mud, sand and gravel from splashing onto the cargo strapping and causing damage.

[0020] When goods placed on a logistics flatbed truck need to be bundled, the power source 3 and winch mechanism 2 can be used to easily release the bundled straps, making it convenient to bundle the goods. After the goods on the logistics flatbed truck are untied, one end of the bundled strap can be secured to the rotating shaft 2.1 between the two limit plates 2.2. Then, the power source 3 and the cable guide 11 are turned on, which automatically and neatly winds the bundled straps onto the rotating shaft 2.1, easily achieving automated storage of bundled straps up to 400-600 meters long. This reduces the difficulty and time of storing bundled straps, reduces labor, and alleviates labor intensity. At the same time, it can effectively prevent the bundled straps from knotting when winding or unwinding, avoid cutting the bundled straps, and ensure their long-term use.

[0021] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
