Description

Technical Field

[0001] This utility model relates to the field of loading trolley technology, specifically to a hydraulic loading trolley. Background Technology

[0002] Currently, the typical structure of a traditional hydraulic loading trolley includes: a fixed chassis: a rectangular frame structure with rails installed at the bottom, and a hydraulic lifting device fixed above the chassis via connecting plates; a hydraulic lifting system: composed of hydraulic cylinders, oil pumps, and control valves, which drives the hopper to lift and lower via a manual or electric pump; and a fixed hopper: the bottom of the hopper is fixedly connected to the chassis, allowing only vertical lifting and not horizontal rotation. The workflow is as follows: the operator places the material on the pallet → the hydraulic system is activated to lift to a fixed height → the loading trolley moves horizontally to load the material → it descends.

[0003] The existing loading trolley has the following problems:

[0004] 1. High dependence on site space:

[0005] Because the hopper cannot rotate, the entire trolley must be aligned with the discharge port during unloading. If the space is narrow (such as in workshop aisles or multi-equipment layouts), the trolley must be moved multiple times or sufficient turning space must be provided, resulting in:

[0006] The minimum working space must meet the overall turning radius of the vehicle (usually ≥5 meters);

[0007] Narrow areas (such as passageways less than 5 meters wide) do not allow for flexible operation.

[0008] 2. Low operating efficiency:

[0009] Each loading and unloading operation requires frequent movement of the forklift, especially when operating at multiple workstations. Operators need to spend a lot of time adjusting the position of the forklift, increasing the time consumption by 30% to 50%.

[0010] Based on the above, this utility model proposes a hydraulic loading trolley, which can effectively solve the above problems. Utility Model Content

[0011] The purpose of this invention is to provide a hydraulic loading trolley. This hydraulic loading trolley has a simple structure and is easy to use. Through the cooperation of the hydraulic system and the rotating mechanism, a single person can complete the loading and unloading operations. It is highly adaptable, and the rotation and lifting functions of the bracket can meet the loading needs at different heights and angles.

[0012] This utility model is achieved through the following technical solution:

[0013] A hydraulic loading trolley includes two inner support plates and two outer support plates. The inner support plates are located inside the outer support plates. A first rotating shaft is rotatably connected between the middle of the two inner support plates, and the middle of the outer support plates is also rotatably connected to the first rotating shaft. A support column is connected between the bottom of the two outer support plates. A bracket is rotatably connected to the top of the inner support plates. A sliding groove is provided on the bracket, and the outer support plates are slidably connected to the sliding groove. A hydraulic cylinder is rotatably connected to the support column. The push rod of the hydraulic cylinder is rotatably connected to the bottom of the bracket. A rotating mechanism is provided on the bracket, and a tray is provided on the rotating mechanism.

[0014] The purpose of this invention is to provide a hydraulic loading trolley. This hydraulic loading trolley has a simple structure and is easy to use. Through the cooperation of the hydraulic system and the rotating mechanism, a single person can complete the loading and unloading operations. It is highly adaptable, and the rotation and lifting functions of the bracket can meet the loading needs at different heights and angles.

[0015] Preferably, a connecting shaft is rotatably connected between the two inner support plates. The connecting shaft extends to the outside of the inner support plate and is connected to a first pulley. A first sprocket is fixed on the connecting shaft. A motor support plate is connected between the two inner support plates. A hydraulic motor is provided on the motor support plate. A second sprocket is connected to the hydraulic motor. The first sprocket and the second sprocket are connected by chain drive. A second pulley is provided on the outside of the outer support plate. Both the first pulley and the second pulley are slidably connected to a guide rail.

[0016] Preferably, the rotating mechanism includes a motor and a rotary bearing. The motor is fixedly mounted on the bottom of the bracket, and a second rotating shaft is fixedly mounted on the bottom of the tray. The second rotating shaft is rotatably connected to the rotary bearing, and the second rotating shaft passes through the bracket and is fixedly connected to the first gear. A second gear is connected to the motor shaft of the second motor, and the first gear and the second gear mesh with each other.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0018] The hydraulic loading trolley of this invention has a simple structure and is easy to use. Through the cooperation of the hydraulic system and the rotating mechanism, a single person can complete the loading and unloading operations. It is highly adaptable, and the rotation and lifting functions of the bracket can meet the loading needs at different heights and angles. The specific benefits are as follows:

[0019] 1. Significantly reduces site space requirements:

[0020] The rotating hopper eliminates the need to move the forklift as a whole, and the minimum working space only needs to accommodate the forklift's own footprint. The turning radius is reduced from 5m to a single-channel loading and unloading (only the rotation radius of the turntable), allowing for flexible operation in narrow spaces.

[0021] 2. Work efficiency increased by more than 50%:

[0022] Eliminating the need for frequent vehicle relocation reduces the average loading / unloading time from 2 minutes to 1 minute, with even greater efficiency advantages when operating at multiple workstations (e.g., reducing switching time between 3 workstations by 40%).

[0023] 3. Enhanced equipment versatility:

[0024] It is suitable for various unloading scenarios (such as high-level silos, multi-directional workstations, and sites with large limitations), requires no customized modification, and is compatible with existing production line layouts. Attached Figure Description
