[0002] Cargo loading and unloading is an essential and important link in the logistics and production fields. It refers to the operations of loading and unloading goods during the transportation production process. Cargo loading and unloading is generally carried out at designated locations, and goods are loaded into or unloaded from transportation equipment (such as vehicles, ships, airplanes, etc.) manually or mechanically. There are various ways of cargo loading and unloading. Manual loading and unloading is one of them. Workers carry out loading and unloading operations by carrying on the shoulders or using simple tools. This method is flexible and convenient and is widely used in the processes of warehousing, logistics centers for goods warehousing, outbound, sorting, etc.
[0003] When manually loading and unloading goods from a freight car, generally two people operate. One person uses a forklift vehicle to lift the shelf platform, and the goods are stacked on the shelf platform. One person conducts loading or unloading operations on the freight car. When the goods are being loaded and unloaded, collisions will occur between the goods and between the goods and the shelf platform. Although the buffer impact can be reduced by setting steel springs, rubber, elastomers, etc. on the lower-layer shelf platform, when the goods are stacked, slight collisions will still occur between the upper-layer goods, and the impact force between the stacked upper-layer goods cannot be reduced, thus ensuring that the impact force can be effectively reduced during the loading and unloading process.

[0028] Embodiment
[0029] Please refer to Figures 1 to 7, the present utility model provides a technical solution: a buffer device for loading and unloading goods, including a buffer frame for loading and unloading goods, which includes a base 11 and a vertical frame 12 at one corner position of the bottom end perpendicular to the base 11. The base 11 and the gantry-shaped vertical frame 12 are firmly screwed together. The forklift vehicle can lift the base 11. Goods are stored in layers on the buffer frame for loading and unloading goods composed of the base 11 and the vertical frame 12 to facilitate the loading and unloading of goods; a goods support inclined plate 3 hinged to the vertical frame 12 through a spring on one side. In the initial state without goods, the goods support inclined plate 3 is in an inclined state close to the vertical direction of the vertical frame 12. When placing goods, it is necessary to rotate the goods support inclined plate 3 from top to bottom so that the goods support inclined plate 3 is in an inclined state tending to the horizontal direction. The goods are placed on the surface of the goods support inclined plate 3 with a certain slope. Under the action of gravity, the goods slide towards the inclined bottom end of the goods support inclined plate 3, and the goods squeeze the buffer assembly 4. Support members are provided on both the other side of the goods support inclined plate 3 and one side of the base 11. The support member includes a stabilizing rod 21 and a support rod 22 rotatably connected to one end of the stabilizing rod 21. The stabilizing rod 21 is welded to the corresponding base 11 and the goods support inclined plate 3. A fixed sleeve is provided at the bottom end of the support rod 22. The stabilizing rod 21 passes through the fixed sleeve, and the fixed sleeve rotates around the position of the stabilizing rod 21 to change the position of the support rod 22. The support rod 22 is embedded inside the goods support inclined plate 3. The support rod 22 is limited by the goods support inclined plate 3, and the goods support inclined plate 3 is supported by the support rod 22. A buffer rubber pad 32 is provided on the surface of the goods support inclined plate 3 close to the stabilizing rod 21. The surface of the buffer rubber pad 32 is provided with damping patterns to increase the friction between the buffer rubber pad 32 and the goods support inclined plate 3 and prevent the goods support inclined plate 3 from sliding; a buffer assembly 4 installed on one surface of the goods support inclined plate 3. The buffer assembly 4 includes a stabilizing plate 41 fixedly connected to the goods support inclined plate 3, a buffer plate 42 slidably contacting the surface of the goods support inclined plate 3, a fixing plate 43 installed on the buffer plate 42, a guiding column 44 passing through the fixing plate 43 and having one end connected to the stabilizing plate 41, and a buffer spring 45 sleeved outside the guiding column 44. The buffer plate 42 is parallel to the stabilizing plate 41. The stabilizing plate 41 is screwed to the goods support inclined plate 3 through bolts. The fixing plate 43 is screwed to the buffer plate 42 through screws. The guiding column 44 is screwed to the stabilizing plate 41 through threads. When the goods press down the buffer plate 42, the fixing plate 43 squeezes the buffer spring 45, and the buffer spring 45 contracts, which can slow down the impact between the goods and the goods support inclined plate 3 and protect the goods from damage.
[0030] In this embodiment, both ends of the stabilizing rod 21 are 90-degree elbow structures, and the support rod 22 is a "U" - shaped structure. A slot 34 matching the support rod 22 is opened on one surface of the goods support inclined plate 3. The top end of the support rod 22 is embedded inside the slot 34 to limit the support rod 22. The support rod 22 supports the goods support inclined plate 3 to keep the goods and the goods support inclined plate 3 stable.
[0031] In this embodiment, a rectangular groove is formed on one surface of the goods support inclined plate 3. A support frame 33 in the shape of a frame is provided in the rectangular groove of the goods support inclined plate 3. The support frame 33 is welded to the goods support inclined plate 3 to form an integral structure. The surface of the buffer rubber pad 32 is fitted with the opposite surface of the support frame 33. The buffer rubber pad 32 is adhesively connected to the support frame 33 through glue. The surface of the buffer rubber pad 32 on the same side as the goods support inclined plate 3 is flush. The goods are fitted with the surfaces of the buffer rubber pad 32 and the goods support inclined plate 3.
[0032] In this embodiment, a stop bar 31 is provided at the side position of the goods support inclined plate 3. The stop bar 31 is threadedly connected to the goods support inclined plate 3. The stop bar 31 blocks the goods to prevent the goods from sliding out from both sides. A forklift truck groove 111 is provided on the bottom surface of the base 11, which is beneficial for the forklift truck to lift the base 11.
[0033] In this embodiment, the fixing plate 43 has a "U" - shaped structure. One end of the guide post 44 has a "T" - shaped structure. The guide post 44 is limited by the fixing plate 43. The fixing plate 43 presses the buffer spring 45. The stabilizing plate 41 and the buffer plate 42 are perpendicular to the goods support inclined plate 3, and the stabilizing plate 41 and the buffer plate 42 are parallel.
[0034] In this embodiment, a stretching component is provided inside the goods support inclined plate 3. The stretching component includes a moving block 51 connected to the end of the buffer plate 42, a pulling rope 52 with one end connected to the moving block 51, a diagonal support column 54 connected to the other end of the pulling rope 52, a damping plate 53 connected to one end of the diagonal support column 54, and a lifting plate 55 connected to the other end of the diagonal support column 54. The diagonal support column 54 is welded to the lifting plate 55 and the damping plate 53. The lifting plate 55 is in an inclined state. The mutually parallel lifting plate 55 is fitted with the opposite surface of the buffer rubber pad 32. The diagonal support column 54 is inclined and installed between the damping plate 53 and the lifting plate 55. When the goods press the buffer plate 42 and make it move a certain position, the moving block 51 moves. The moving block 51 stretches the pulling rope 52, and the pulling rope 52 is in a taut state. The diagonal support column 54, the damping plate 53 and the lifting plate 55 form an integral seesaw. The pulling rope 52 generates a force to pull the integral seesaw to move, so that the integral seesaw generates a force to tilt the buffer rubber pad 32 outwards, thereby making the buffer rubber pad 32 be in close contact with the goods, increasing the friction between the buffer rubber pad 32 and the goods. In fact, the integral seesaw will not tilt the buffer rubber pad 32 out of the goods support inclined plate 3, but only generates a force to tilt the buffer rubber pad 32, achieving the effect of the buffer rubber pad 32 being closely attached to the goods, increasing the resistance received by the goods, and preventing the goods with a certain slope from sliding obliquely due to vibration during the transportation by the forklift truck.
[0035] In this embodiment, the damping plate 53 includes a contact plate and a bent plate. One side of the lifting plate 55 is connected to the bent plate. The contact plate fits the inner surface of the goods support inclined plate 3. The lifting plate 55 is parallel to the contact plate. The damping plate 53 and the lifting plate 55 support the middle position of the buffer rubber pad 32.
[0036] The working principle and usage process of the present utility model:
[0037] When manually disassembling goods from a freight truck, the forklift forks up the base 11 and rotates the inclined goods support inclined plate 3 at the bottom layer connected by a spring hinge from top to bottom. At the same time, the angle of the rotating rod 22 is rotated so that the goods support inclined plate 3 is supported by the rotating rod 22.
[0038] Place the goods on the surface of the inclined goods support inclined plate 3. The goods support inclined plate 3 slides under the action of gravity, and the goods support inclined plate 3 acts on the buffer plate 42.
[0039] The buffer plate 42 moves under the action of the goods. The fixing plate 43 on the buffer plate 42 presses the buffer spring 45, and the buffer spring 45 contracts, which can slow down the impact between the goods and the goods support inclined plate 3 and protect the goods from damage.
[0040] The goods contact the buffer rubber pad 32 on the surface of the goods support inclined plate 3. There is friction between the buffer rubber pad 32 and the goods to prevent the goods from shaking.
[0041] When the goods squeeze the buffer plate 42 and make it move a certain position, the buffer plate 42 is subjected to a force F1, the moving block 51 moves, and the moving block 51 stretches the pull rope 52.
[0042] At this time, the pull rope 52 is in a taut state. The inclined strut 54, the damping plate 53 and the lifting plate 55 form a seesaw integral body. The pull rope 52 generates a force to pull the seesaw integral body to move, so that the seesaw integral body generates a force F2 to lift the buffer rubber pad 32 outward, thereby making the buffer rubber pad 32 closely contact the goods and increasing the friction between the buffer rubber pad 32 and the goods.
[0043] In fact, the force F1 exerted by the goods on the buffer plate 42 can be divided into a vertical force a1 and a horizontal force a2. The buffer plate 42 is subjected to the horizontal force a2, and the seesaw integral body will not lift the buffer rubber pad 32 out of the goods support inclined plate 3, but only generates a force F2 to lift the buffer rubber pad 32. The force F2 can be divided into a vertical force b1 and a horizontal force b2. The horizontal force b2 acts on the buffer rubber pad 32 to achieve the effect of closely fitting the buffer rubber pad 32 with the goods, increasing the resistance received by the goods, and preventing the goods on a certain slope from sliding obliquely due to vibration during forklift transportation.
[0044] After placing goods on the bottommost goods support inclined plate 3, lower the adjacent upper-layer goods support inclined plate 3 and place goods on it. Repeat the above operations to achieve the purpose of placing goods in layers.
[0045] In summary: There is a design for placing stacked goods in layers and for anti-collision and buffering of the layered goods. The multi-layer goods support inclined plate 3 is designed such that goods can be placed on each layer of the goods support inclined plate 3. The buffer rubber pads 32 and the buffer components 4 play a role in reducing the impact force of the goods and preventing the goods from being damaged.
[0046] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
