A trolley-based rapid loading and unloading auxiliary device

Abstract

This utility model relates to the field of trolley unloading technology, specifically a trolley rapid loading and unloading auxiliary device, including a base, which is U-shaped, with self-locking casters movably mounted on the lower surface of the base. The device is first connected to a factory power supply or powered by a portable lithium battery. The device is moved to the transport vehicle compartment. When loading and unloading are required, the device is first moved to the target position and fixed using the self-locking casters. A hydraulic pump (a commercially available product) is then started. The hydraulic rod extends, pushing connecting rod two to rotate around the connection point, causing the scissor structure formed by connecting rod one and connecting rod two to unfold. At this time, pulley one rolls along guide rail one on the lower surface of the platform, and pulley two slides along guide rail two on the upper surface of the base, jointly driving the platform to rise smoothly to the required height. The movable plate rises, and the roller slides upward through the sliding rod of the auxiliary component. When the movable plate slides past the roller, it automatically tilts towards the vehicle compartment, allowing goods to be pushed into the compartment via the tilting plate.

Description

Technical Field

[0001] This utility model relates to the field of trolley unloading technology, and in particular to an auxiliary device for rapid loading and unloading of trolleys. Background Technology

[0002] In logistics warehousing, factory workshops, and retail distribution, trolleys are widely used as short-distance transportation tools. However, traditional trolley loading and unloading requires manual handling of goods across height differences, resulting in low efficiency, high labor intensity, and a high risk of goods collisions and personnel injuries. Especially when dealing with transport vehicles or storage racks of different heights, the height mismatch between the trolley and the target location further exacerbates the loading and unloading difficulties. There is an urgent need for a flexible, adjustable, and easy-to-operate auxiliary device to optimize the loading and unloading process.

[0003] Based on the above background, the device design needs to meet the following requirements: First, it should have a height adjustment function to adapt to the height differences of different loading and unloading scenarios; second, it should have a stable structure and be easy to move, enabling it to be quickly transferred and fixed between different work points; third, it should provide a continuous and smooth loading and unloading channel to reduce the resistance of cargo handling; fourth, it should be easy to operate, reducing the skill requirements for operators; and fifth, it should have sufficient load-bearing capacity and durability to adapt to the needs of high-frequency operations, ultimately achieving the goal of improving loading and unloading efficiency and reducing labor costs and operational risks.

[0004] Therefore, we propose a trolley-based rapid loading and unloading auxiliary device. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a trolley-based rapid loading and unloading auxiliary device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A trolley-based rapid loading and unloading auxiliary device includes a base, which is U-shaped. Four self-locking casters are movably mounted on the lower surface of the base. A platform, also U-shaped, is movably mounted on the upper surface of the base. An inclined plate is fixedly mounted on one side of the platform. A movable plate is rotatably connected to the side of the platform away from the inclined plate via a pivot. Lifting components are mounted on the lower surfaces of both sides of the platform. A fixed plate is fixedly mounted on the side of the base near the movable plate. An auxiliary component is mounted on the upper surface of the fixed plate.

[0008] As a further embodiment of this utility model: the lifting assembly includes a hydraulic pump, the hydraulic pump is fixedly installed on the side of the fixing plate away from the platform, a protruding plate is fixedly installed on the upper surface of the base, there are two protruding plates, the two protruding plates are rotatably connected to a connecting rod on the side close to each other by a rotating shaft, there are two connecting rods, the ends of the two connecting rods away from the protruding plates are rotatably connected to a pulley by a rotating shaft, there are two pulleys.

[0009] As a further embodiment of this utility model: a guide rail is fixedly installed on the lower surface of the pedestal, and there are two guide rails. The pulley is engaged with the guide rail in a rolling engagement connection.

[0010] As a further embodiment of this utility model: the two connecting rods are rotatably connected to each other via a rotating shaft, and there are two connecting rods. The top of each connecting rod is rotatably connected to a convex plate, and there are two convex plates. The convex plates are fixedly installed on the lower surface of the base.

[0011] As a further embodiment of this utility model: the bottom end of the connecting rod 2 is rotatably connected to pulley 2 via a rotating shaft, and there are two pulleys 2. The upper surface of the base is fixedly installed with guide rail 2, and there are two guide rails 2. The pulley 2 and guide rail 2 are rolled and engaged.

[0012] As a further embodiment of this utility model: hydraulic rods are rotatably connected inside the two connecting rods one via a rotating shaft, and a connecting frame is fixedly installed inside the two connecting rods two. The connecting frame is inclined, and the output end of the hydraulic rod is rotatably connected to the connecting frame via a rotating shaft. The hydraulic rod and the hydraulic pump are fixedly connected via a hydraulic pipe.

[0013] As a further embodiment of this utility model: the auxiliary component includes a groove on the upper surface of the fixed plate, there are two grooves, a slide rod is slidably connected inside the groove, a fixing hole is opened on the side of the slide rod near the hydraulic pump, a limit hole is opened on the side of the fixed plate near the hydraulic pump, a pin is inserted into the limit hole, the pin is connected to the fixing hole, and a roller is rotatably connected to the top of the slide rod through a rotating shaft, the roller is rotatably connected to the movable plate.

[0014] Compared with the prior art, this utility model provides a trolley-based quick loading and unloading auxiliary device, which has the following beneficial effects:

[0015] 1. In this utility model, the lifting assembly drives hydraulic rods on the lower surfaces of both sides of the platform through a hydraulic pump. Linkage rod one and linkage rod two form a scissor-type lifting structure. Combined with the rolling cooperation of pulleys and guide rails, the platform can achieve smooth lifting and adjustment, which can adapt to loading and unloading needs of different heights. The lifting assemblies on both sides of the platform have the same structure. The auxiliary assembly supports the movable plate through adjustable sliding rods and rollers, which can provide buffer guidance during unloading and can also achieve multi-level support through pin fixation, greatly improving the safety and efficiency of the loading and unloading process. It is especially suitable for the rapid transfer of small and medium-sized goods.

[0016] 2. This utility model features a continuous loading and unloading channel formed by an inclined plate and a rotatable movable plate. Combined with the height adjustment function of the lifting assembly, it can easily connect transport vehicles of different heights (such as trucks, warehouse shelves, etc.), reducing handling resistance during cargo transfer. The lifting assembly uses a hydraulic drive, ensuring stable and controllable lifting force. Furthermore, the coordinated design of the connecting rods and pulleys reduces mechanical wear and extends the equipment's service life. The auxiliary component's sliding rod adjustment structure can be flexibly adjusted according to the height of the vehicle compartment, preventing deformation caused by impact when the movable plate is tilted. The entire device is simple to operate, allowing a single person to complete loading and unloading operations, significantly reducing labor costs and labor intensity.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description
