Description

Technical Field

[0001] This utility model relates to the field of loading equipment technology, and more specifically to a loading assembly line. Background Technology

[0002] Loading equipment is widely used in logistics warehousing, production workshops, and cargo handling for temporary stacking, sorting, and transfer of goods. Traditional loading platforms are mostly fixed-height structures. When stacking or picking goods, workers need to frequently bend over or stand on tiptoe to adapt to different heights of cargo layers. Long-term operation can easily lead to fatigue in the back and joints of workers, affecting work efficiency and increasing labor intensity.

[0003] To improve operational comfort, height-adjustable loading platforms have emerged in existing technologies, employing hydraulic, electric, or manual mechanical methods for lifting and lowering. However, these devices typically require manual intervention or rely on external power sources, are structurally complex, have high manufacturing costs, and suffer from high maintenance requirements, high energy consumption, and slow response times during frequent use. Furthermore, the platforms are prone to impacts or vibrations during lifting and lowering, which is detrimental to the safe handling of fragile or delicate goods. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a loading assembly line cart. This loading assembly line cart features a cleverly designed purely mechanical adaptive floating mechanism that successfully upgrades a static loading device into a dynamic auxiliary tool that automatically responds to load changes, effectively reducing the labor intensity of workers and improving operational safety and efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A loading conveyor includes a seat, a support frame on one side of the seat, a loading platform vertically slidably connected to the support frame, and an adaptive floating mechanism between the loading platform and the support frame. The adaptive floating mechanism includes a central seat, a movable pulley, a fixed pulley, and a connecting rope. The central seat is vertically slidably connected to the support frame, the movable pulley is mounted on the central seat, an elastic connector is provided between the bottom of the central seat and the bottom of the support frame, the fixed pulley is mounted on the top of the support frame, one end of the connecting rope is connected to the top of the support frame, passes through the movable pulley and the fixed pulley in sequence, and the other end is connected to the loading platform.

[0006] Furthermore, the upright frame is provided with vertically arranged first slide rails on both sides, and the loading platform is provided with first sliders on both sides, the first sliders being slidably connected to the first slide rails.

[0007] Furthermore, two columns are provided in the middle of the support frame, and a second slide rail is provided on each of the two columns. Second sliders are provided on both sides of the middle seat, and the second sliders are slidably connected to the second slide rails.

[0008] Furthermore, the elastic connector includes several springs, which are arranged side by side and connected at one end to the bottom of the intermediate seat and at the other end to the bottom of the upright.

[0009] Furthermore, protective sleeves are fitted onto the outer sides of several springs.

[0010] Furthermore, fixing rings are provided on the top of the stand and the loading platform, and the two ends of the connecting rope are fixed to the top of the stand and the loading platform respectively through the fixing rings.

[0011] Furthermore, the movable pulley, fixed pulley, and connecting rope are each provided in two sets and are symmetrically distributed.

[0012] Furthermore, the bottom of the seat is equipped with several casters.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. Ergonomic optimization reduces labor intensity: This invention completely changes the traditional working method of fixed-height platforms or platforms requiring manual / power adjustment. When workers are stacking or picking goods, the loading platform can automatically adjust its height according to the real-time load, keeping the working surface in the most comfortable and labor-saving operating range near the worker's body. Workers do not need to frequently bend over or stand on tiptoe, effectively reducing fatigue and injury to the lower back and joints.

[0014] 2. Improve operational efficiency and achieve streamlined operations: Because the loading platform can automatically maintain the optimal working height, workers do not need to be distracted by adjusting the equipment. The gripping action is more direct and faster, significantly shortening the cycle time of a single operation. This is especially important in assembly line operations, as it can smooth the work rhythm and improve the overall efficiency of material handling and sorting.

[0015] 3. Passive self-adaptation, simple and reliable structure: The entire self-adaptation process is achieved entirely through a clever mechanical structure (pulley block, spring, slider), without the need for sensors, controllers or external power (such as electricity or hydraulics). The structure is simple, the manufacturing cost is low, the failure rate is low, and maintenance is not required.

[0016] 4. Smooth operation and protection of goods: Through the cooperation of elastic elements (springs) and guide mechanisms (slide rails and sliders), the loading platform can remain stable during the descent under load and the ascent under no load, effectively buffering the impact and avoiding damage to goods caused by sudden platform descent or collision. It is especially suitable for handling fragile or precision items.

[0017] This invention successfully upgrades a static loading device into a dynamic auxiliary tool that automatically responds to load changes through an ingenious purely mechanical adaptive floating mechanism, effectively reducing the labor intensity of workers and improving operational safety and efficiency.

They should not be construed as limiting the specific protection scope of this utility model.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature.

[0022] A type of loading conveyor belt, such as Figure 1-4As shown, the device includes a seat 1, a support frame 2 on one side of the seat 1, a loading platform 3 vertically slidably connected to the support frame 2, and an adaptive floating mechanism between the loading platform 3 and the support frame 2. The adaptive floating mechanism includes an intermediate seat 8, a movable pulley 9, a fixed pulley 4, and a connecting rope 12. The intermediate seat 8 is vertically slidably connected to the support frame 2. The movable pulley 9 is mounted on the intermediate seat 8. An elastic connector is provided between the bottom of the intermediate seat 8 and the bottom of the support frame 2. The fixed pulley 4 is mounted on the top of the support frame 2. One end of the connecting rope 12 is connected to the top of the support frame 2, passes through the movable pulley 9 and the fixed pulley 4 in sequence, and the other end is connected to the loading platform 3.

[0023] Preferably, the upright frame 2 is provided with vertically arranged first slide rails on both sides, and the loading platform 3 is provided with first sliders on both sides, and the first sliders are slidably connected to the first slide rails.

[0024] Preferably, two columns 6 are provided in the middle of the support frame 2, and a second slide rail is provided on each of the two columns 6. A second slider is provided on both sides of the middle seat 8, and the second slider is slidably connected to the second slide rail.

[0025] Preferably, the elastic connector includes several springs 11, which are arranged side by side and connected at one end to the bottom of the intermediate seat 8 and at the other end to the bottom of the upright 2. Specifically, the springs 11, as elastic elements, are connected between the intermediate seat 8 and the bottom of the upright 2. When the load on the loading platform 3 changes, the springs 11 are compressed or extended. The height of the loading platform 3 is adjusted by the system of the movable pulley 9 and the connecting rope 12 to achieve adaptive floating. This can effectively buffer the impact caused by load changes, enabling the loading platform 3 to automatically adapt to weight changes, maintain stable operation, reduce damage to items, and improve operational safety.

[0026] Preferably, a protective sleeve 10 is fitted on the outside of several springs 11. Specifically, the protective sleeve 10 covers the outside of the springs 11 to form a physical isolation, preventing dust and debris from entering or the springs 11 from being mechanically damaged, extending the service life of the springs 11, reducing the maintenance frequency, and ensuring that the elastic connector can still work reliably in harsh environments.

[0027] Preferably, a fixing ring 5 is provided on the top of the upright frame 2 and the loading platform 3. The two ends of the connecting rope 12 are fixed to the top of the upright frame 2 and the loading platform 3 respectively through the fixing ring 5. Specifically, the fixing ring 5 serves as the anchor point of the connecting rope 12. The two ends of the connecting rope 12 are fixed to the top of the upright frame 2 and the loading platform 3 respectively by mechanical fixing, forming a stable force transmission path. This can prevent the connecting rope 12 from slipping or loosening, ensure that the pulley system is subjected to uniform force, and improve the reliability and safety of the entire mechanism.

[0028] Preferably, the movable pulley 9, the fixed pulley 4, and the connecting rope 12 are provided in two sets and are symmetrically distributed; specifically, the two sets of pulleys and the connecting rope 12 are symmetrically arranged on both sides of the intermediate seat 8 to form a balanced force transmission system. By changing the direction of force and distributing the load through the pulley group, the load-bearing capacity and stability of the mechanism are enhanced, and the tilting caused by uneven force on one side of the loading platform 3 is prevented.

[0029] Preferably, the bottom of the seat 1 is provided with a plurality of rollers 7. Specifically, the rollers 7 are installed at the bottom of the seat 1 to enable the movement of the entire equipment, improve the mobility of the loading conveyor, facilitate rapid transfer between different working positions, improve work efficiency, and reduce manual handling costs.

[0030] The core of this invention is an intermediate seat 8, which is provided with elastic force by a spring 11. A pulley system consisting of a movable pulley 9, a fixed pulley 4, and a connecting rope 12 links the loading platform 3 and the intermediate seat 8. When goods are placed on the loading platform 3, the weight is converted into a downward pulling force on the intermediate seat 8 through the connecting rope 12, compressing the spring 11 and causing the loading platform 3 to descend. When the goods are removed, the spring 11 returns to its original position, and the loading platform 3 is raised through the pulley system.

[0031] Automatic, passive adjustment of the height of loading platform 3 is achieved. When stacking goods, loading platform 3 descends smoothly under elastic support, making it easy to continue stacking; when removing goods, loading platform 3 can automatically rise, always keeping the top layer of goods at a height that is easy for workers to reach, without the need for manual intervention or the use of external energy.

[0032] advantage: 1. Ergonomic optimization reduces labor intensity: This utility model completely changes the traditional working method of fixed-height platforms or platforms requiring manual / power adjustment. When workers are stacking or picking goods, the loading platform 3 can automatically adjust its height according to the real-time load, keeping the working plane in the most comfortable and labor-saving operating range near the worker's body. Workers do not need to frequently bend over or stand on tiptoe, effectively reducing fatigue and injury to the lower back and joints.

[0033] 2. Improved operational efficiency and streamlined operation: Because loading platform 3 can automatically maintain the optimal working height, workers do not need to be distracted by adjusting the equipment. The gripping action is more direct and faster, significantly shortening the cycle time of a single operation. This is especially important in assembly line operations, as it can smooth the work rhythm and improve the overall efficiency of material handling and sorting.

[0034] 3. Passive self-adaptation, simple and reliable structure: The entire self-adaptation process is achieved entirely through a clever mechanical structure (pulley block, spring 11, slider), without the need for sensors, controllers or external power (such as electricity or hydraulics). The structure is simple, the manufacturing cost is low, the failure rate is low, and maintenance is not required.

[0035] 4. Smooth operation and protection of goods: Through the cooperation of elastic elements (spring 11) and guide mechanism (slide rail slider), the loading platform 3 can remain stable during the loading descent and unloaded ascent, effectively buffering the impact and avoiding damage to goods caused by sudden platform drop or collision. It is especially suitable for handling fragile or precision items.

[0036] This invention successfully upgrades a static loading device into a dynamic auxiliary tool that automatically responds to load changes through an ingenious purely mechanical adaptive floating mechanism, effectively reducing the labor intensity of workers and improving operational safety and efficiency.
