Description

Technical Field

[0001] This utility model relates to the field of cargo loading and unloading, and in particular to a cargo loading and unloading device with a multi-directional buffer component. Background Technology

[0002] In the fields of industrial production and logistics transportation, steel cylinders, as a common pressure vessel, are widely used for storing and transporting various industrial gases and liquefied gases. They are characterized by their large weight, thick walls, and high internal pressure. During handling, they are easily damaged by rolling and collisions, which may not only cause dents, scratches, or even structural damage to the cylinder body, affecting its service life, but more seriously, may damage the cylinder valve, leading to gas leakage and causing safety accidents. Therefore, the loading, unloading, and handling of steel cylinders place high demands on operational safety and equipment reliability.

[0003] Traditional gas cylinder handling relies heavily on manual hydraulic pallet trucks, secured with simple brackets or straps. However, the reliance on straps for fixation lacks effective multi-directional flexible cushioning components. When the pallet truck moves or traverses uneven surfaces, the gas cylinders are prone to rigid collisions with the brackets and the pallet truck, or significant shaking. This makes the gas cylinders easily damaged upon impact, increasing safety risks during handling. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a cargo loading and unloading device with multi-directional buffer components, which aims to improve the problem that "traditional handling vehicles lack multi-directional flexible buffer components" in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a cargo loading and unloading device with a multi-directional buffer assembly, comprising a transport vehicle, a placement frame provided on the left side of the transport vehicle, a buffer assembly provided inside the placement frame, the buffer assembly comprising a fixed plate, a rubber pad, a slider, a positioning rod, a sliding rod, a spring, a through hole and a circular sleeve, a locking assembly provided at the top of the fixed plate, the fixed plate being fixedly installed on the front side of the placement frame by bolts, the slider being slidably connected to the rear inner wall of the fixed plate by a dovetail rectangular block, the positioning rod being fixedly connected to the front surface of the slider, the sliding rod being fixedly connected to the front surface of the slider and located at the center, the circular sleeve being fixedly connected to the front surface of the fixed plate, the sliding rod penetrating the fixed plate and piston-connected to the inner wall of the circular sleeve, the spring being elastically connected between the sliding rod and the circular sleeve, the through hole being opened at the center of the front surface of the circular sleeve, and the positioning rod penetrating and slidably connected to the fixed plate.

[0006] As a further description of the above technical solution: The locking assembly includes a locking block, a rod, and a socket. The locking block is rotatably connected to the top of the fixed plate, the socket is opened at the top of the fixed plate, and the rod passes through the locking block and is inserted into the inner wall of the socket.

[0007] As a further description of the above technical solution: An elastic sheet is fixedly connected to the top of the two sets of fixing plates near the right side, and a rubber pad is fixedly connected to the left side of the elastic sheet.

[0008] As a further description of the above technical solution: The rubber pad is fixedly connected to the top of the placement frame near the left side. The fixing plate, slider, slide rod and circular sleeve are all set in two groups and are symmetrically arranged with the center line of the placement frame as the axis of symmetry.

[0009] As a further description of the above technical solution: The rear surface of the positioning rod is designed as an arc surface.

[0010] As a further description of the above technical solution: One end of the spring is fixedly connected to the front surface of the slide rod, and the other end of the spring is fixedly connected to the front side of the inner wall of the sleeve.

[0011] As a further description of the above technical solution: The top of the insertion rod is cone-shaped.

[0012] As a further description of the above technical solution: The locking block is designed in an L-shape.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the slider, the sliding rod, the spring, and the circular sleeve cooperate with each other. The slider slides along the fixed plate, the sliding rod moves in a piston-like manner inside the circular sleeve and compresses the spring. At the same time, the air inside the circular sleeve is discharged to generate damping force, which effectively absorbs and disperses the impact force, preventing the gas cylinder from being damaged on the surface or internal structure due to excessive impact. In addition, the setting of the elastic sheet further assists in absorbing lateral force, realizing a multi-directional buffering effect, ensuring the safety of the gas cylinder during the handling process in all aspects, reducing the risk of damage to the gas cylinder due to impact during handling, and extending the service life of the gas cylinder.

[0014] 2. In this utility model, two sets of locking blocks can form a U-shape to stably wrap and limit the position of the gas cylinder, preventing it from sliding to the left during transportation. The locking blocks are quickly fixed to the fixing plate by inserting the plug rod into the plug hole, ensuring that the gas cylinder remains stable during transportation. At the same time, the rubber pads set on the inner side of the locking blocks and the contact parts of the device not only increase the contact area and friction with the gas cylinder, further improving the fixing effect, but also prevent the surface of the gas cylinder from being scratched, ensuring the appearance quality of the gas cylinder. This prevents the gas cylinder from causing safety accidents due to shaking or slipping during transportation, thus improving the safety and stability of the transportation process.

[0017] 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.

[0018] Reference Figure 1 - Figure 3This utility model provides an embodiment of a cargo loading and unloading device with a multi-directional buffer assembly, including a transport vehicle 1 for transporting steel cylinders. A placement rack for placing steel cylinders is provided on the left side of the transport vehicle 1. Inside the placement rack is a buffer assembly 2 for cushioning and supporting the steel cylinders to reduce impact. The buffer assembly 2 includes a fixed plate 21 providing support and enclosure, a rubber pad 22 that increases the contact area and friction with the steel cylinder while providing cushioning through its own elasticity, a slider 23 that wraps and supports the steel cylinder, and a positioning rod that supports the slider 23 for stable sliding. 24. A sliding rod 25, which provides a buffering effect by using the elastic force of the spring 26 to reset the slider 23; a spring 26, which buffers the cylinder by restoring the cylinder through the elastic force after being compressed; a through hole 27, which provides a damping effect to the movement of the sliding rod 25 and the slider 23 by venting air; and a circular sleeve 28, which provides a buffering effect to the cylinder by using the sliding rod 25, the spring 26, and the slider 23. The top of the fixing plate 21 is provided with a locking component 3 to lock the cylinder securely. The fixing plate 21 is fixedly installed on the front side of the placement frame by bolts and can be disassembled after installation by bolts.

[0019] Furthermore, slider 23 is slidably connected to the rear inner wall of fixed plate 21 via dovetail rectangular block. The dovetail rectangular block increases the stability of slider 23's sliding. Positioning rod 24 is fixedly connected to the front surface of slider 23 to stably support slider 23. Slide rod 25 is fixedly connected to the front surface of slider 23 and located at the center to cooperate with spring 26 to give slider 23 a buffering effect. Circular sleeve 28 is fixedly connected to the front surface of fixed plate 21. Slide rod 25 passes through fixed plate 21 and is piston-connected to the inner wall of circular sleeve 28. Through piston connection and through hole 27, slide rod 25 has a certain damping force when moving, thereby preventing slider 23 from excessive rebound. Spring 26 is elastically connected between slide rod 25 and circular sleeve 28. One end of spring 26 is fixedly connected to the front surface of slide rod 25, and the other end of spring 26 is fixedly connected to the front side of inner wall of circular sleeve 28. Through hole 27 is opened at the center of the front surface of circular sleeve 28 to cooperate with slide rod 25 to expel air from inner wall of circular sleeve 28, thereby producing a damping effect.

[0020] Furthermore, the positioning rod 24 is connected to the fixing plate 21 through and slidably. The rear surface of the positioning rod 24 is set as an arc surface, which is used to adapt to the arc surface of the steel cylinder, thereby increasing the contact area with the steel cylinder and providing a better cushioning effect. The rubber pad 22 is fixedly connected to the top of the placement frame near the left side. The fixing plate 21, slider 23, sliding rod 25 and round sleeve 28 are all set in two sets and are symmetrically arranged with the center line of the placement frame as the axis of symmetry. The two sets of symmetrical arrangement can stably support the steel cylinder. The top of the two sets of fixing plates 21 is fixedly connected to the right side with an elastic sheet 29 for multi-directional cushioning of the steel cylinder. Through the elastic force of the elastic sheet 29, it can cooperate with the slider 23 to provide multi-directional cushioning of the steel cylinder. The left side of the elastic sheet 29 is fixedly connected to a rubber pad 210 for further contact with the steel cylinder to increase the contact area and cushioning effect. The inner side of the arc shape of the opposite face of the two sets of sliders 23 is fixed with a rubber pad 3.

[0021] Reference Figure 1 - Figure 3 The locking assembly 3 includes an L-shaped locking block 31 that can wrap and limit the position of the steel cylinder, a rod 32 for inserting into the socket 33 to limit the locking block 31, and the socket 33. The locking block 31 is L-shaped, which can form a U-shape after two sets are set, thereby stably limiting the position of the steel cylinder and preventing it from sliding to the left, thus increasing the stability of loading and unloading the steel cylinder. The locking block 31 is rotatably connected to the top of the fixing plate 21. The socket 33 is opened at the top of the fixing plate 21. The rod 32 passes through the locking block 31 and is inserted into the inner wall of the socket 33. The top of the rod 32 is conical, which makes it easy to insert a finger and move it upward. Rubber pads are fixed on the inner side of both sets of locking blocks 31.

[0022] Working principle: When using the gas cylinder, first pull the conical rod 32 upwards to disengage it from the insertion hole 33, then rotate the two sets of L-shaped locking blocks 31 to open them. Next, place the gas cylinder on the placement rack. The gas cylinder first contacts the rubber pad 22, and the elasticity of the rubber pad 22 initially cushions the impact during placement. Simultaneously, the outer wall of the gas cylinder adheres to the rubber pads 3 on the opposite sides of the two sets of sliders 23 and the rubber pad 210 on the left side of the elastic sheet 29. The rubber pads 210 and 3 increase the contact area and friction with the gas cylinder, further enhancing the cushioning effect. The pressure of the gas cylinder pushes the slider 23 to slide along the dovetail rectangular block on the inner wall of the rear side of the fixed plate 21. The positioning rod 24 moves synchronously with the slider 23 and provides stable support. The sliding rod 25 moves piston-like along the inner wall of the sleeve 28 under the action of the slider 23. At this time, the air inside the sleeve 28 is discharged through the through hole 27, generating a damping force. To prevent excessive rebound of the slider 23, the slide rod 25 compresses the spring 26, and the spring 26 acts in the opposite direction on the slider 23 through elastic force. Combined with the elastic deformation of the elastic plate 29, this achieves multi-directional buffering of the cylinder in the radial and circumferential directions, reducing impact damage during handling. After the cylinder is placed in position, the two sets of locking blocks 31 are rotated in the opposite direction to form a U-shape to wrap around the cylinder. The insertion rod 32 passes through the locking block 31 and is inserted into the insertion hole 33 to complete the locking and limiting of the cylinder. The rubber pad on the inner side of the locking block 31 further enhances the fixing stability and prevents scratches on the cylinder surface. During handling, the fixing plate 21 is fixed to the placement frame with bolts to ensure the overall structure is stable. The cooperation of the slider 23, slide rod 25, spring 26 and round sleeve 28 continuously buffers the impact force generated by road bumps or turns, while the elastic plate 29 helps to absorb lateral forces, ensuring the safety and stability of the cylinder in all aspects during loading, unloading and handling.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
