Description

TECHNICAL FIELD

[0001] The utility model relates to the field of downhill buffer plate, specifically to a downhill buffer plate for logistics trolley transportation. BACKGROUND

[0002] In the modern logistics industry, logistics trolleys are widely used for short-distance transportation and handling of goods. In places such as logistics warehouses and distribution centers, due to the need for site layout and goods storage methods, logistics trolleys often need to transport between platforms or floors of different heights, which inevitably encounters uphill and downhill situations.

[0003] When the logistics trolley goes downhill, its speed will gradually increase due to the effect of gravity. Without effective buffering measures, the excessive speed may cause a series of problems:

[0004] Safety risks: High-speed downhill trolleys may collide due to difficulty in control, not only causing damage to the trolley itself, but also endangering surrounding workers, goods, and other equipment and facilities, leading to safety accidents.

[0005] Goods damage: The impact force generated when going downhill may cause the goods on the trolley to shake, tip over, or even fall, resulting in damage to the goods packaging and products, causing economic losses.

[0006] Trolley wear: Frequent and rapid downhill impact will cause significant wear and pressure on the trolley's wheels, frame, and other components, shortening the trolley's service life and increasing equipment maintenance costs. Therefore, we propose a downhill buffer plate for logistics trolley transportation. INVENTION CONTENTS

[0007] (I) Technical problems solved

[0008] To address the shortcomings of existing technology, the utility model provides a downhill buffer plate for logistics trolley transportation, which solves the above problems.

[0009] (II) Technical solutions

[0010] To achieve the above purposes, the utility model provides the following technical solutions: a downhill buffer plate for logistics trolley transportation, comprising a bottom triangular block, one side of the bottom triangular block is installed with an inclined slope upward, one end of the inclined slope is fixedly installed with a flat apron, the bottom of the apron is provided with a cushion block, a plurality of groups of rectangular grooves are equally spaced on the inclined slope, and a plurality of groups of speed reduction assemblies are arranged inside the rectangular grooves.

[0011] Preferably, the two sides of the inclined slope are fixedly installed with side baffles.

[0012] Preferably, a notch is provided on the bottom triangular block, and a blocking plate is hinged to the bottom triangular block at the position corresponding to the notch. Multiple sets of elastic components are equidistantly arranged on the inner wall of the notch.

[0013] Preferably, the elastic component includes a circular fixing block, a spring, and a lifting block. The circular fixing block is fixedly installed on the inner wall of the notch, and the spring is fixedly installed inside the circular fixing block. The lifting block is inserted into the inside of the circular fixing block, and the lower end of the lifting block is fixedly connected to the spring. When the spring rebounds normally, the lifting block abuts against the bottom of the blocking plate, and the blocking plate tilts upward.

[0014] Preferably, the deceleration assembly includes a support plate and a roller, the roller being rotatably mounted on the support plate, and the support plate being located inside a rectangular groove.

[0015] Preferably, fixed guide rectangular blocks are fixedly installed on both sides of the bottom of the inclined slope corresponding to the rectangular groove. Side grooves are opened on the side wall of the fixed guide rectangular blocks that are close to each other. A second spring is fixedly installed inside the side groove. A protrusion is integrally formed on the bearing plate at the position corresponding to the side groove. The protrusion is slidably installed inside the side groove, and the lower end of the protrusion is fixedly connected to the upper end of the second spring.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a downhill buffer plate for logistics cart transportation, which has the following beneficial effects:

[0018] 1. This logistics trolley uses a downhill buffer plate with multiple sets of deceleration components installed on the inclined slope. The rollers of these components can rotate and move up and down under the action of springs. When the trolley's rollers pass over the rollers, the rollers are compressed, causing the springs to contract. The springs then rebound, thus buffering the impact force on the trolley and effectively reducing its downhill speed. Simultaneously, a movable baffle plate on the bottom triangular block rotates downwards under pressure, overcoming the elastic force of the components. This process further buffers the impact force on the trolley, reducing its speed when passing over the bottom triangular block and ensuring a smooth transition to the ground.

[0019] 2. The downhill buffer plate for this logistics vehicle features a multi-stage buffer structure, from the base plate to the slope and then to the bottom triangular block. The vehicle first slows down on the slope using the deceleration components, and then is further buffered at the bottom triangular block with the help of the blocking plate and elastic components. The multi-stage buffer design greatly improves the buffering effect and reduces the impact force of the vehicle going downhill.

[0020] 3. The downhill buffer plate for the logistics cart and the side baffles installed on both sides of the inclined slope can effectively prevent the cart from falling off the side of the inclined slope during the descent, avoid safety accidents such as cargo falling, cart damage and personnel injury caused by the cart skidding, and ensure that the cart slides down the predetermined route safely.

[0021] 4. The downhill buffer plate used in this logistics vehicle reduces the shaking and impact of the vehicle when going downhill through its excellent deceleration and buffering effect. This lowers the risk of damage to goods due to collisions and bumps during transportation, thereby improving the integrity and quality of cargo transportation and reducing economic losses caused by cargo damage.

[0022] 5. The downhill buffer plate for logistics vehicles has a relatively simple structure, with components such as deceleration components and elastic components, making its processing and manufacturing relatively easy. Furthermore, the materials used, such as springs and baffles, are common and readily available, resulting in a relatively low overall manufacturing cost for the buffer plate and facilitating its widespread application in the logistics industry.

[0023] 6. This downhill buffer plate for logistics cart transportation is easy to use. Simply align the pad with the step, place the bottom triangular block, and then place the mounting plate on the pad to complete the installation. The operation is simple and quick, requiring no professional tools or complicated installation procedures. It can quickly adapt to the downhill requirements of different sites and improve logistics operation efficiency. Attached Figure Description

[0031] 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.

[0032] Please see Figures 1-6 A downhill buffer plate for transporting logistics trolleys includes a bottom triangular block 4, an upward-sloping ramp 3 installed on one side of the bottom triangular block 4, a flat plate 2 fixedly installed at one end of the ramp 3, a pad 1 at the bottom of the plate 2, and multiple sets of rectangular grooves 5 evenly spaced on the ramp 3. Multiple sets of deceleration components 6 are installed inside the rectangular grooves 5. When needed, the pad 1 is aligned with the step, the pad 1 is pressed against the step surface, the bottom triangular block 4 is placed on the ground, and then the plate 2 is placed on the pad 1. When the trolley moves, it passes over the surface of the pad 1 and onto the plate 2, and then moves down the ramp 3. The multiple sets of deceleration components 6 act as a barrier to slow down the trolley, and then it falls to the ground after passing the bottom triangular block 4, thus providing a buffer.

[0033] Furthermore, side baffles 7 are fixedly installed on both sides of the inclined slope 3. By adding side baffles 7, the trolley can be prevented from falling off the side of the inclined slope 3 when it moves down the inclined slope 3.

[0034] Furthermore, a notch 8 is provided on the bottom triangular block 4, and a blocking plate 9 is hinged to the bottom triangular block 4 at the position corresponding to the notch 8. Multiple sets of elastic components are equidistantly arranged on the inner wall of the notch 8.

[0035] Furthermore, the elastic component includes a circular fixing block 10, a spring 11, and a lifting block 12. The circular fixing block 10 is fixedly installed on the inner wall of the notch 8, and the spring 11 is fixedly installed inside the circular fixing block 10. The lifting block 12 is inserted into the circular fixing block 10, and the lower end of the lifting block 12 is fixedly connected to the spring 11. When the spring 11 rebounds normally, the lifting block 12 abuts against the bottom of the blocking plate 9. At this time, the blocking plate 9 tilts upward. When the trolley moves downward and passes the bottom triangular block 4, the trolley roller contacts the blocking plate 9 and presses it downward. Then the blocking plate 9 presses down on the lifting block 12, and the spring 11 contracts. When the downward tilt angle of the blocking plate 9 is the same as the tilt angle of the bottom triangular block 4, the blocking plate 9 will cover the notch 8. Then the trolley roller passes. This device can buffer the downward-moving trolley by setting a downward-moving block, reducing the impact force and movement speed when passing the bottom triangular block 4.

[0036] Furthermore, the deceleration assembly 6 includes a support plate 16 and a roller 18, the roller 18 being rotatably mounted on the support plate 16, and the support plate 16 being located inside the rectangular groove 5.

[0037] Furthermore, fixed guide rectangular blocks 13 are fixedly installed on both sides of the bottom of the inclined slope 3 corresponding to the rectangular groove 5. Side grooves 14 are opened on the side wall of the fixed guide rectangular blocks 13 that are close to each other. Spring 15 is fixedly installed inside the side groove 14. A protrusion 17 is integrally formed on the bearing plate 16 corresponding to the side groove 14. The protrusion 17 is slidably installed inside the side groove 14, and the lower end of the protrusion 17 is fixedly connected to the upper end of the spring 15. When the spring 15 rebounds normally, the roller 18 will extend through the rectangular groove 5 to the surface of the inclined slope 3. When the trolley passes over the surface of the inclined slope 3, its rollers will pass over the roller 18 and then press down on the roller 18. Then the spring 15 rebounds. This device adds a downward-pressing obstruction to the surface of the inclined slope 3, which can reduce the impact force when the trolley passes over the inclined slope 3 and provide buffering.

[0038] Structural Description:

[0039] Pad 1: Located at the bottom of the platform 2, it needs to be aligned with the step when in use so that it fits the step surface and serves to support the platform 2, providing basic support for the trolley to transition from the step to the platform 2.

[0040] Platform 2: It is flat, with one end fixedly connected to the inclined slope 3, and the bottom is supported by pad 1. It is the transition plane for the trolley to enter the inclined slope 3 from the steps. The trolley first walks across the surface of pad 1 onto platform 2, and then moves down the inclined slope 3.

[0041] Inclined ramp 3: Installed at an upward angle on one side of the bottom triangular block 4, with multiple sets of rectangular slots 5 evenly spaced on the surface, and side baffles 7 fixedly installed on both sides. Inclined ramp 3 provides a slope for the trolley to slide downhill, the rectangular slots 5 are used to install the deceleration assembly 6, and the side baffles 7 prevent the trolley from falling off the side during the descent.

[0042] Bottom triangular block 4: Located at the bottom of the buffer plate, connected to the inclined ramp 3 on one side. Its surface has a notch 8, and a blocking plate 9 is hinged at the corresponding notch 8. After the car decelerates via the inclined ramp 3, it falls to the ground via the bottom triangular block 4. During this process, the bottom triangular block 4 and its associated structures provide further cushioning for the car.

[0043] Rectangular grooves 5: are opened on the inclined slope 3 and are evenly distributed. Each set of rectangular grooves 5 is equipped with a deceleration assembly 6, providing installation space for the deceleration assembly 6.

[0044] The deceleration assembly 6 includes a support plate 16 and a roller 18. The roller 18 is rotatably mounted on the support plate 16, which is located inside the rectangular groove 5. Fixed guide rectangular blocks 13 are fixed to both sides of the bottom of the inclined slope 3 corresponding to the rectangular groove 5. Springs 15 within the side grooves 14 of these blocks are connected to protrusions 17 on the support plate 16. When the trolley rollers pass over the roller 18, the roller 18 is compressed, causing the spring 15 to contract. When the spring 15 rebounds, it buffers the impact force of the trolley, thus achieving a deceleration effect.

[0045] Side baffles 7: Fixedly installed on both sides of the inclined slope 3, their function is to prevent the trolley from falling off the side as it moves down the inclined slope 3, thus ensuring the safe operation of the trolley on the inclined slope 3.

[0046] Notch 8: Opened on the bottom triangular block 4, for mounting the baffle plate 9 and the elastic component, providing space for the movement of the baffle plate 9 and the setting of the elastic component.

[0047] Baffle 9: Hinged at the position corresponding to notch 8 of the bottom triangular block 4, it normally tilts upward under the action of the elastic component. When the trolley rollers come into contact with baffle 9, they will press down on it. When the downward tilt angle of baffle 9 is the same as the tilt angle of the bottom triangular block 4, it will cover notch 8, allowing the trolley rollers to pass through, thereby buffering the trolley and reducing the impact force and movement speed when passing the bottom triangular block 4.

[0048] Circular fixing block 10: It is fixedly installed on the inner wall of the notch 8 as a fixing base for the elastic component, and is used to install spring 11 inside.

[0049] Spring 11: One end is fixed inside the circular fixing block 10, and the other end is connected to the lifting block 12. During normal rebound, the lifting block 12 is pushed against the bottom of the blocking plate 9, causing the blocking plate 9 to tilt upward; when the trolley roller presses down on the blocking plate 9, spring 11 contracts, which plays a buffering role.

[0050] Lifting block 12: Inserted inside the circular fixed block 10, with its lower end fixedly connected to spring 11. Under the action of spring 11, it presses against the bottom of the blocking plate 9, and under the action of the trolley, it moves downward with the blocking plate 9 and compresses spring 11.

[0051] Fixed guide rectangular block 13: Fixedly installed on both sides of the rectangular groove 5 at the bottom of the inclined slope 3. Its function is to provide a sliding track for the protrusion 17 on the bearing plate 16, so as to ensure that the bearing plate 16 and the roller 18 can move up and down stably when subjected to force.

[0052] Side groove 14: It is formed on the side wall of the fixed guide rectangular blocks 13 that are close to each other. Spring 2 15 is installed inside to provide sliding space for the protrusion 17 and at the same time restrict the movement direction of the protrusion 17.

[0053] Spring 2 15: Fixed inside the side groove 14, with its upper end connected to the protrusion 17 on the support plate 16. During normal rebound, it extends the roller 18 to the surface of the inclined slope 3; when the trolley roller presses down on the roller 18, spring 2 15 contracts, using its own elastic deformation to buffer the impact force of the trolley.

[0054] The bearing plate 16 is located inside the rectangular groove 5 and is used to install the roller 18. It has a protrusion 17 integrally formed at the position corresponding to the side groove 14. The protrusion 17 is connected to the spring 15 in the side groove 14 to realize the function of the roller 18 moving up and down on the surface of the inclined slope 3.

[0055] Protrusion 17: An integrally formed structure on the support plate 16, which is slidably installed inside the side groove 14. Its lower end is fixedly connected to the upper end of the second spring 15. Under the action of the second spring 15, it drives the support plate 16 and the roller 18 to move up and down.

[0056] Roller 18: Rotatably mounted on the bearing plate 16. When the second spring 15 rebounds normally, the roller 18 extends to the surface of the inclined slope 3. When the trolley roller passes by, the roller 18 rotates and can be pressed down. Through the interaction with the trolley roller and the elastic buffer of the second spring 15, the impact force when the trolley passes by the inclined slope 3 is reduced.

[0057] Working principle: When needed, align pad 1 with the step and make pad 1 fit against the step surface. Place the bottom triangular block 4 on the ground and then place the platform 2 on pad 1. When the trolley moves, it passes over the surface of pad 1 and walks onto platform 2. Then it moves down the inclined slope 3. The multiple deceleration components 6 can act as a barrier to slow down the trolley. Finally, it falls to the ground through the bottom triangular block 4 for cushioning.

[0058] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
