Description

Technical Field

[0001] This invention relates to the field of material handling equipment technology, and more specifically, to a clamping device for a box-transfer transport vehicle. Background Technology

[0002] In existing technologies, manual transfer is usually used to transport wheeled transfer containers over short to medium distances in narrow passages. For example, for garbage bins located near residential areas, which are used to hold various types of household waste, once the garbage bins are full, they are manually transported from the vicinity of the residential areas to the side of the road, and then garbage trucks clean up the garbage inside the garbage bins.

[0003] However, when garbage bins are full, they are quite heavy, especially medium and large garbage bins, which can weigh up to two tons when full. It is time-consuming, labor-intensive, and costly for people to move garbage bins without any mechanical or tool assistance.

[0004] Therefore, using container transport vehicles to replace manual labor for transporting wheeled containers such as garbage bins in narrow passages has become a development trend. However, when using container transport vehicles to transport containers, if there are potholes or slopes on the road during the transport process, the containers (such as garbage bins) are prone to tipping over, which can lead to danger and low safety.

[0005] Therefore, ensuring the reliability and safety of transporting wheeled containers (such as garbage bins) in narrow passages using container transport vehicles is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a clamping device for a box transport vehicle, which can ensure the reliability and safety of transport.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A clamping device for a box-carrying transport vehicle includes:

[0009] Shelves used for carrying loads;

[0010] A drive mechanism connected to the rack is used to drive the rack to lift and lower.

[0011] The clamping mechanism has an open state and a clamping state. When the clamping mechanism is in the clamping state, it can fix the casters at the bottom of the transfer box; when the clamping mechanism is in the open state, it can release the casters.

[0012] Preferably, the carrier has a receiving groove for accommodating the casters, and one side of the receiving groove is open; when the clamping mechanism is in the clamping state, the clamping mechanism closes the opening to clamp the casters into the receiving groove; when the clamping mechanism is in the open state, the clamping mechanism avoids the opening.

[0013] Preferably, the clamping mechanism includes:

[0014] A clamping element, which is slidably disposed on the shelf;

[0015] An elastic element is connected between the shelf and the clamping element, the elastic element being used to drive the clamping element into the opening to close the opening.

[0016] Preferably, the clamping mechanism further includes:

[0017] The first end of the traction rope is hinged to the clamping member, and the second end of the traction rope is hinged to the frame of the box transport vehicle.

[0018] A roller, which is rotatably mounted on the frame, and the traction rope is wound around the roller;

[0019] When the rack is at its lowest position, the traction rope tightens the clamping member, causing the clamping member to compress the elastic member to avoid the opening; during the process of raising the rack, the first end moves closer to the second end, causing the traction rope to loosen the clamping member, so that the elastic member drives the clamping member to extend into the opening.

[0020] Preferably, the traction rope is provided with a locking point, and the load frame is provided with a limiting part for cooperating with the locking point to limit the movement.

[0021] Preferably, the load-bearing frame is provided with a top plate, and the top plate is provided with a limiting post; the end of the clamping member facing the elastic member is provided with an extension post; the elastic member is a spring, one end of the spring is sleeved on the limiting post and abuts against the top plate, and the other end of the spring is sleeved on the extension post and abuts against the clamping member.

[0022] Preferably, the rack is hinged to a connecting rod, and the end of the connecting rod away from the rack is used to hinge to the frame of the box transport vehicle. The rack, the connecting rod, and the frame form a parallelogram linkage mechanism.

[0023] Preferably, the drive mechanism includes a hydraulic cylinder, one end of which is hinged to the cargo rack and the other end of which is hinged to the vehicle frame.

[0024] Preferably, the cylinder is a double-acting piston cylinder.

[0025] The clamping device for a transporter's box body provided by this invention involves placing a carrying frame at the bottom of a transport box (such as a garbage bin) to support it, and engaging a clamping mechanism to secure the casters at the bottom of the transport box. This clamping mechanism then fixes the transport box (such as a garbage bin) to the clamping device. Based on this, a transporter's box body using this clamping device can be used to transport the transport box (such as a garbage bin) in narrow passages.

[0026] Because the clamping device of the transport tractor can fix the transport container (such as a garbage can), it can ensure the reliability and safety of the transport container (such as a garbage can) in narrow passages, and avoid the transport container (such as a garbage can) from tipping over due to potholes or slopes on the road surface during the transport process, thus improving safety.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] The core of this invention is to provide a clamping device for a box transport vehicle, which can ensure the reliability and safety of transport.

[0040] Please refer to Figures 1-8 , Figure 1 An exploded view of the clamping device for a box-carrying transport vehicle provided in a specific embodiment of the present invention; Figure 2 for Figure 1 A first-person view of the assembled structure; Figure 3 for Figure 2 A structural diagram from a second perspective; Figure 4 for Figure 2 A structural diagram from a third-person perspective; Figure 5 A top view of the clamping mechanism in the open position; Figure 6 for Figure 5 Side view; Figure 7 This is a top view of the clamping mechanism in the clamping state. Figure 8 for Figure 7 A side view. Among them, Figure 1 In the exploded view shown, reference numeral 9 represents a component of the chassis; other components of the chassis are not shown.

[0041] This invention provides a clamping device for a container transport vehicle, comprising a carrying frame 1, a drive mechanism, and a clamping mechanism. The carrying frame 1 is used to support and carry transport containers (such as garbage containers); the drive mechanism is connected to the carrying frame 1 and is used to drive the carrying frame 1 to rise and fall; the clamping mechanism has an open state and a clamped state. When the clamping mechanism is in the clamped state, it can fix the casters at the bottom of the transport container; when the clamping mechanism is in the open state, it can release the casters at the bottom of the transport container.

[0042] It should be noted that when not in use, the drive mechanism can drive the rack 1 to the lowest position so that the rack 1 is in the retracted state. At the same time, the clamping mechanism is preferably in the open state so that when in use, the clamping mechanism can be changed from the open state to the clamping state to fix the casters at the bottom of the transfer box.

[0043] In use, the carrying rack 1 is placed at the bottom of the transfer box (such as a garbage can) so that the carrying rack 1 supports the transfer box (such as a garbage can) and the clamping mechanism is in a clamping state. The clamping mechanism is used to fix the casters at the bottom of the transfer box, thereby fixing the transfer box (such as a garbage can) to the clamping device of the box transfer vehicle. Based on this, the box transfer vehicle using the clamping device of the box transfer vehicle can be used to transfer the transfer box (such as a garbage can) in narrow passages.

[0044] Because the container transport vehicle uses a clamping device to secure the transport container (such as a garbage can), it ensures the reliability and safety of transporting the container (such as a garbage can) in narrow passages, and avoids the container (such as a garbage can) from tipping over due to potholes or slopes on the road surface during transport, thus improving safety.

[0045] It should be noted that the specific structure of the clamping mechanism is not limited in this embodiment, as long as it can fix the casters at the bottom of the transfer box (such as a garbage can). For example, it can be a structure in which the clamping mechanism includes at least two retractable clamps. By extending and retracting each clamp, all clamps can be brought together or separated. When all clamps are brought together, they can restrict the casters at the bottom of the transfer box (such as a garbage can). When all clamps are separated, they can release the casters at the bottom of the transfer box (such as a garbage can).

[0046] Considering structural simplicity, as a preferred embodiment, based on the above embodiment, the shelf 1 is provided with a receiving groove 11 for accommodating casters, with one side of the receiving groove 11 open. When the clamping mechanism is in the clamping state, it closes the opening to confine the casters within the receiving groove 11; when the clamping mechanism is in the open state, it avoids the opening. In other words, this embodiment utilizes the receiving groove 11 on the shelf 1 to circumferentially limit the casters of the transfer box, and cooperates with the clamping mechanism to fix or release the casters of the transfer box within the receiving groove 11. That is, when the clamping mechanism closes the opening, it clamps the casters of the transfer box, thus fixing them. It can be seen that this embodiment only requires the clamping mechanism to extend to or retract from the opening of the receiving groove 11, which simplifies the structure of the clamping mechanism.

[0047] It should be noted that this embodiment does not limit the specific structure of the clamping mechanism. For example, the clamping mechanism can be a telescopic rod. When the telescopic rod extends, it can close the opening of the receiving groove 11. When the telescopic rod retracts, it can avoid the opening.

[0048] Furthermore, to avoid requiring a dedicated power source to extend the clamping mechanism into the opening of the receiving groove 11, based on the above embodiment, the clamping mechanism includes a clamping member 2 and an elastic member 3. The clamping member 2 is slidably disposed on the shelf 1, and the elastic member 3 is connected between the shelf 1 and the clamping member 2. The elastic member 3 is used to drive the clamping member 2 into the opening of the receiving groove 11 to close the opening. In other words, this embodiment utilizes the elastic force of the elastic member 3 to drive the clamping member 2 into the opening of the receiving groove 11. When an external force is applied to the clamping member 2 to compress the elastic member 3, the elastic member 3 can undergo elastic deformation, thereby allowing the clamping member 2 to avoid the opening of the receiving groove 11.

[0049] Furthermore, this embodiment does not limit the method by which the clamping member 2 applies external force to compress the elastic member 3. Considering the simplicity of the structure and to save power, based on the above embodiment, the clamping mechanism also includes a traction rope 4 and a roller 5. The traction rope 4 is preferably a steel wire rope. The first end of the traction rope 4 is hinged to the clamping member 2, and the second end of the traction rope 4 is used to hinge to the frame 9 of the box transport vehicle. At the same time, the traction rope 4 is wound around the roller 5, and the roller 5 is rotatably mounted on the carrying rack 1. When the carrying rack 1 is in the lowest position, the traction rope 4 tightens the clamping member 2, causing the clamping member 2 to compress the elastic member 3 to avoid the opening. During the process of raising the carrying rack 1, the first end of the traction rope 4 approaches its second end, causing the traction rope 4 to loosen the clamping member 2, so that the elastic member 3 drives the clamping member 2 to extend into the opening of the receiving groove 11. Understandably, as the rack 1 descends from its highest position to its lowest position, the first end of the traction rope 4 gradually moves away from its second end, causing the traction rope 4 to gradually tighten the clamping member 2, thereby causing the clamping member 2 to squeeze the elastic member 3 and causing the clamping member 2 to avoid the opening of the receiving groove 11.

[0050] In other words, this embodiment uses the lifting and lowering movement of the carrier 1 to change the relative positional relationship between the first end and the second end of the traction rope 4, thereby causing the traction rope 4 to tighten or loosen the clamping member 2. In conjunction with the elastic member 3, the clamping member 2 can be inserted into the opening of the receiving groove 11 or avoid the opening.

[0051] It should be noted that this embodiment does not limit the specific positions of the first and second ends of the traction rope 4, as long as the above-mentioned movement requirements can be met. Preferably, the fixed position of the second end of the traction rope 4 is adjustable, so that the position of the clamping member 2 is adjustable when it is in the open state and the clamping state.

[0052] In addition, this embodiment does not limit the way the roller 5 is set on the shelf 1. Preferably, the roller 5 is hinged to the shelf 1 through a bushing.

[0053] It is understandable that by using the traction rope 4 to pull the clamping member 2 to apply external force to the clamping member 2, since the traction rope 4 is a flexible part, the carrying frame 1 can be moved at any angle and position. The traction rope 4 is not affected by the height difference and angle of the carrying frame 1. Therefore, it is convenient to design the movement of the carrying frame 1, while reducing the processing and assembly difficulty.

[0054] Furthermore, during the raising of the shelf 1, to prevent the traction rope 4 from becoming too loose and detaching from the roller 5, based on the above embodiment, the traction rope 4 is provided with a locking point, and the shelf 1 is provided with a limiting part for cooperating with the locking point to limit its movement. That is to say, in this embodiment, the limiting part is used to limit the locking point on the traction rope 4. When the locking point of the traction rope 4 moves to the limiting part as the shelf 1 rises, the limiting part stops and limits the locking point, preventing it from continuing to move. This ensures that the traction rope 4 from the locking point to the roller 5 always has a certain tension and will not loosen, thereby preventing the traction rope 4 from detaching from the roller 5.

[0055] It should be noted that this embodiment does not limit the specific structure of the locking point. It can be understood that the diameter of the locking point is larger than the diameter of the traction rope 4. In addition, this embodiment does not limit the specific structure of the limiting part. Preferably, the limiting part is a pressure plate 13 provided on the carrier 1. The pressure plate 13 is provided with a limiting groove or limiting hole for the traction rope 4 to pass through but the locking point cannot pass through.

[0056] It should be noted that the specific structure and arrangement of the elastic element 3 are not limited in the above embodiments. As a preferred embodiment, based on the above embodiments, the shelf 1 is provided with a top plate 14, and the top plate 14 is provided with a limiting post 141; the end of the clamping member 2 facing the elastic element 3 is provided with an extension post 21; the elastic element 3 is a spring, one end of the spring is sleeved on the limiting post 141 and abuts against the top plate 14, and the other end of the spring is sleeved on the extension post 21 and abuts against the clamping member 2. It can be understood that the limiting post 141 and the extension post 21 can guide a section of the spring at both ends to avoid the spring from tilting during extension and retraction; in addition, the top plate 14 and the clamping member 2 limit the ends of the spring respectively.

[0057] It should be noted that the specific structure of the clamping member 2 is not limited in the above embodiments. Preferably, the clamping member 2 is a rod-shaped clamping member 2. Furthermore, the connection method between the clamping member 2 and the traction rope 4 is not limited in the above embodiments. Preferably, an adapter sleeve is fitted onto the rod-shaped clamping member 2, and a protruding hinge handle is provided on the side of the adapter sleeve. The wire rope is connected to the hinge handle. Further, considering the limitation of the sliding stroke of the clamping member 2, preferably, the rack 1 is provided with a groove 12, and the rod-shaped clamping member 2 is slidably disposed within the groove 12. One side of the groove 12 is provided with a long, narrow slit for the hinge handle to extend out, so that the two ends of the long, narrow slit can be used to limit the two extreme positions of the clamping member 2 respectively.

[0058] Furthermore, in the above embodiments, the number of clamping member 2, elastic member 3, traction rope 4, and roller 5 can each be one, forming a clamping mechanism. The opening can be closed by inserting one clamping member 2 into the opening of the receiving groove 11. Of course, the number of clamping member 2, elastic member 3, traction rope 4, and roller 5 can also be two, forming two clamping mechanisms. Preferably, the two clamping mechanisms are symmetrically arranged so that the relative movement of the two clamping members 2 causes them to abut against each other, thereby jointly closing the opening of the receiving groove 11.

[0059] Furthermore, to further improve the reliability of the transfer process, it is preferable to install a backrest on the container transfer vehicle using the clamping device of the container transfer vehicle. This backrest provides support to the sides of the transfer container, ensuring a safer transfer process. In this case, to bring the rack 1 closer to the backrest during the lifting process so that the transfer container contacts the backrest, based on the above embodiment, the rack 1 is hinged to a connecting rod 6. The end of the connecting rod 6 away from the rack 1 is hinged to the frame 9 of the container transfer vehicle. The rack 1, the connecting rod 6, and the container transfer vehicle form a parallelogram linkage mechanism. It is understandable that since the rack 1, the link 6 and the frame 9 of the box transfer vehicle form a parallelogram linkage mechanism, when the rack 1 is driven to rise and fall by the drive mechanism, the link 6 swings, causing the height of the rack 1 to change. At the same time, the position of the rack 1 in the horizontal plane also changes. That is, the rack 1 rises and moves horizontally at the same time, which ensures that the rack 1 is close to the backing rack during the rising process.

[0060] It should be noted that the specific number of connecting rods 6 is not limited in this embodiment. Preferably, there are four connecting rods 6, which are arranged in pairs at both ends of the frame 1 and are arranged in parallel.

[0061] Preferably, the rack 1 is hinged to the connecting rod 6 via a pin 8, and the connecting rod 6 is hinged to the frame 9 via a pin 8.

[0062] It should be noted that during the raising of the rack 1, the clamping mechanism first secures the casters of the transfer box. Afterward, the rack 1 continues to rise until the side of the transfer box contacts the backrest. That is, during the securing process of the transfer box, the clamping device for the box transfer vehicle raises the rack 1 to its final transport height only after the casters are secured. This prevents the transfer vehicle from moving before the casters are secured, which could cause the casters to come loose and create a driving hazard. Conversely, the rack 1 lowers a certain distance from its final transport height before the clamping mechanism releases the casters of the transfer box. This prevents the casters from coming loose before the rack 1 reaches a safe position. Clearly, this makes the clamping device for the box transfer vehicle safer and more reliable.

[0063] In addition, in the above embodiments, the specific structure of the drive mechanism for the rack 1 is not limited, as long as it can drive the rack 1 to rise and fall.

[0064] As a preferred embodiment, based on the above embodiments, the drive mechanism includes a hydraulic cylinder 7, one end of which is hinged to the rack 1, and the other end is hinged to the frame 9. When the hydraulic cylinder 7 extends, the rack 1 can be raised; when the hydraulic cylinder 7 retracts, the rack 1 can be lowered.

[0065] Preferably, based on the above embodiment, the hydraulic cylinder 7 is a double-acting piston cylinder. That is, the extension and retraction of the hydraulic cylinder 7 are both active movements, which makes the speed of raising and lowering the shelf 1 controllable, avoiding the situation where the shelf 1 gets stuck and cannot descend when it is unloaded.

[0066] It should also be noted that, in this specification, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0067] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make several improvements and modifications to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
