Description

Technical Field

[0001] The present invention relates to the field of transportation, and in particular to a cargo handling auxiliary device for vehicle transportation. Background Art

[0002] Traditional cargo handling and transportation requires extensive manual labor, including loading and unloading cargo from the ground onto and from transport vehicles. This method not only consumes significant physical effort but also poses safety risks due to its low safety margin. Furthermore, long hours of handling can lead to physical and mental fatigue among workers, resulting in reduced productivity.

[0003] With the development of science and technology, technicians in related fields have also made a lot of optimizations on the technical means used for vehicle transportation and handling of goods. In order to make a more accurate comparison, for example, a Chinese patent with publication number CN214298399U discloses an operating device for a freight vehicle, including a motor housing, a rotating motor, a fixed base plate, a rotating support plate, a drive motor, a screw, a screw pair, a screw housing, a fixed block and an auxiliary cargo transportation component; when in use, the transfer plate is controlled to rise and fall by the drive motor to realize the lifting and lowering of the goods, and the rotating motor is used to control the rotation of the goods, which is convenient for the staff to carry the goods.

[0004] However, the above operating device still has some shortcomings in actual use: The above-mentioned device controls the up and down movement of the transfer plate through the lead screw and the lead screw pair by a driving motor to realize the lifting and lowering movement of the goods. Since the lead screw needs to be driven by the output shaft of the driving motor to rotate, so as to drive the lead screw pair to drive the transfer plate to move up and down through the upper thread of the lead screw, in actual use, the movement path of the lead screw pair and the transfer plate is relatively fixed. In the process of driving the lead screw pair and the transfer plate to move up / down, the operator needs to wait for the lead screw pair and the transfer plate to move up / down into place before carrying out the goods transportation work. However, there are usually a lot of goods that the operator needs to carry. When transferring through the above-mentioned device, the operator needs to spend more time waiting for the lead screw pair and the transfer plate to slide into place, which will undoubtedly reduce the operator's transportation efficiency.

[0005] Therefore, based on the above-stated viewpoint, there is still room for improvement in the existing technical means for transporting goods by vehicles. Summary of the Invention

[0006] In order to solve the above problems, the present invention provides a cargo handling auxiliary device for vehicle transportation, comprising a movable base plate, to which is connected a transfer assembly for driving the cargo to be lifted, lowered, and slidable. The transfer assembly comprises: The supporting rotating rod is vertically passed through the movable bottom plate, and the upper limit thereof is connected to the limiting guide rail.

The multiple synchronous wheels are arranged at intervals and are jointly covered with a transmission belt. The upper limit of the transmission belt has multiple transfer plates that slide on the limiting guide rail.

[0008] The adjuster is located on the movable base plate and is used to adjust the angle of the transfer plate.

[0012] Preferably, the driven rotating rod and the extending rotating rod are both provided with pulleys, and a synchronous belt limited to the installation frame plate is provided between the two pulleys.

[0013] Preferably, one of the pulleys connected to the extension rotating rod is provided with a plurality of ratchet key slots, and the upper limit position of the extension rotating rod is provided with a pawl corresponding to the plurality of ratchet key slots.

[0014] Preferably, the limiting guide rail includes two connecting guide plates which are symmetrically and spaced apart on the supporting rotating rod, and guide grooves are formed on both sides of the connecting guide plates corresponding to the transmission belts, and the transfer plate is limited on the two connecting guide plates by a driven slider.

[0015] Preferably, a guide groove is formed between the two connecting guide plates and one side of the transmission belt to limit the sliding path of the driven slider and the transfer plate.

[0016] Preferably, the driven slider is in a "T" shape and extends outward to be connected to the transfer plate, and the driven slider is connected to the transmission belt limiter.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1 To the attached Figure 8 The embodiments of the present invention are described in detail.

[0031] The embodiment of the present application discloses a cargo handling auxiliary device for vehicle transportation. The present application is mainly used in the process of transferring and moving goods into the vehicle, and technically achieves the purpose of assisting staff in lifting and lowering the goods to be transported, thereby facilitating the staff to load and unload goods; especially in the handling process, through the mutual cooperation between the supporting rotating rod, the synchronous wheel, the transmission belt and the plurality of transfer plates, the plurality of transfer plates are driven to alternately rise and fall in height, so that the staff can continuously move the goods, thereby greatly improving the efficiency of the staff in handling the goods.

[0032] Example 1: Reference Figure 1 The device, shown in Figure 1, is a cargo handling assistance device for vehicle transport. It includes a mobile base 1 with several rollers attached to its bottom to improve the overall mobility of the device. A transfer assembly 2 is attached to the base 1 to drive the cargo up and down. During use, the cargo to be transported is placed on the transfer assembly 2, which drives the cargo up and down to achieve the effect of driving the cargo to be raised and lowered, thereby facilitating handling by personnel.

[0033] Reference Figures 2 to 4 As shown, the transfer component 2 is used to drive the cargo to be lifted and slid; specifically, the transfer component 2 includes: The support rotating rod 20 is vertically provided on the movable base plate 1 , and its upper limit is connected to the limit guide rail 21 , and the limit guide rail 21 is slidably supported on the movable base plate 1 .

[0034] There are multiple synchronous wheels 22 and they are limited by the connecting rotating rod and are passed through the supporting rotating rod 20. The multiple synchronous wheels 22 are arranged at intervals and are jointly covered with a transmission belt 23. The transmission belt 23 has multiple transfer plates 24 that slide on the limiting guide rail 21.

[0035] The adjuster 25 is located on the movable base plate 1 and is used to adjust the angle of the transfer plate 24 .

[0036] During use, after the staff moves the goods to be transported to the transfer plate 24, they drive the transmission belt 23 and all the synchronous belts 254 to rotate. While the transmission belt 23 rotates and slides, it drives all the connected transfer plates 24 to slide and rise and fall synchronously until it reaches a predetermined height. Then, the support rotating rod 20 is driven to rotate. The rotation of the support rotating rod 20 drives the limiting guide rail 21, the transmission belt 23, all the synchronous belts 254, the transfer plate 24 and the goods to rotate and shift synchronously in the horizontal direction, thereby making it convenient for the staff to remove or transfer the goods to the vehicle.

[0037] Further, refer to Figures 2 to 4As shown, to improve cargo handling efficiency, at least two transfer plates 24 are provided, one on each side of the support rod 20. Specifically, the transfer plates 24 are connected to the two vertical sections of the transmission belt 23. Initially, the transfer plates 24 on either side of the transmission belt 23 are located at the upper and lower sections of the limiting guide rails 21, respectively, so that the rotation and sliding of the transmission belt 23 drive the transfer plates 24 on either side to alternately rise and fall.

[0038] During use, in the process of driving the synchronous belt 254 and the transmission belt 23 to rotate and slide, since several transfer plates 24 are arranged in the vertical sections on both sides of the transmission belt 23, during the rotation and sliding of the transmission belt 23, several transfer plates 24 on both sides of the transmission belt 23 always rotate with the rotation of the transmission belt 23, with one side moving up and up with the rotation of the transmission belt 23, and the other side moving down with the rotation of the transmission belt 23. That is, the transfer plates 24 on both sides of the transmission belt 23 are always in a relative / back-to-back sliding state, so that the staff can move the goods on the transfer plate 24 on one side of the transmission belt 23 that is flush with the vehicle height into the vehicle, and at the same time, the transfer plate 24 on the other side of the transmission belt 23 moves down synchronously so that the staff can move another goods to the transfer plate 24, so that the staff can move goods continuously and efficiently, effectively reducing the waiting time required for staff during the lifting and lowering of goods, and greatly improving the efficiency of staff in moving goods.

[0039] Reference Figure 5 and Figure 6 As shown, the regulator 25 is used to adjust the angle of the transfer plate 24; specifically, the regulator 25 includes a mounting frame plate 250 that is passed through the upper limit position of the movable base plate 1, and a driven rotating rod 251 corresponding to the supporting rotating rod 20 is passed through the mounting frame plate 250, and the driven rotating rod 251 and the supporting rotating rod 20 are connected together through a bevel gear transmission.

[0040] When in use, the driven rotating rod 251 is driven to rotate, and the driven rotating rod 251 rotates through the bevel gear to drive the supporting rotating rod 20 to rotate synchronously. The rotation of the supporting rotating rod 20 drives the limiting guide rail 21, the synchronous wheel 22, the transmission belt 23, the transfer plate 24 and the goods to rotate and adjust synchronously, so that the goods on the transfer plate 24 are rotated relative to the vehicle or staff after the height is raised, so that the staff can move the goods.

[0041] Further, refer to Figures 5 to 7 As shown, an extension rotating rod 252 corresponding to the driven rotating rod 251 is also provided on the installation frame plate 250 in a limited manner, and the extension rotating rod 252 is connected to one of the connecting rotating rods.

[0042] Reference Figures 6 to 8As shown, pulleys 253 are mounted on both the driven rotating rod 251 and the extending rotating rod 252, and a synchronous belt 254 with a slip limiter positioned on the mounting frame 250 is mounted between the two pulleys 253. During use, the extending rotating rod 252 is driven to rotate by conventional motor drive technology. The rotation of the extending rotating rod 252 drives the connected connecting rotating rod and the synchronous wheel 22 to rotate. After the synchronous wheel 22 rotates, it drives another synchronous wheel 22 to rotate synchronously via the transmission belt 23, thereby achieving the synchronous rotation of all the synchronous wheels 22 and the transmission belt 23, thereby driving the transfer plate 24 and the goods on the transfer plate 24 to be raised or lowered.

[0043] At the same time, the synchronous wheel 22 rotates to drive the connected connecting rod to rotate synchronously, and the rotation of the connecting rod drives the extension rod 252 to rotate. The rotation of the extension rod 252 drives the driven rod 251 to rotate through the pulley 253 and the synchronous belt 254, thereby driving the supporting rod 20 to rotate so as to adjust the angle of the transfer plate 24.

[0044] Furthermore, refer to Figure 7 and Figure 8 As shown, one of the pulleys 253 connected to the extension rotating rod 252 is provided with a plurality of ratchet key slots 2530, and the upper limit position of the extension rotating rod 252 is provided with a pawl 2531 corresponding to the plurality of ratchet key slots 2530. The pawl 2531 is rotationally limited on the extension rotating rod 252 by a torsion spring (not shown in the figure).

[0045] During use, when the extension rotating rod 252 is driven to rotate in the forward direction, the pawl 2531 slides through several ratchet key slots 2530, so that the ratchet key slots 2530 (pulley 253) will not be driven by the extension rotating rod 252 to rotate, thereby not driving the driven rotating rod 251 and the supporting rotating rod 20 to rotate, and also not driving the transmission belt 23 and the transfer plate 24 to adjust the angle.

[0046] When the extension rod 252 is driven to rotate in the opposite direction, the pawl 2531 is engaged in the ratchet keyway 2530, so that the extension rod 252 rotates in the opposite direction, and the synchronous belt 254 drives the pawl 2531 and the connected pulley 253 to rotate synchronously, thereby driving the synchronous belt 254, the driven rod 251 and the supporting rod 20 to rotate synchronously through the pulley 253, so as to adjust the rotation of the supporting rod 20, the transmission belt 23 and the transfer plate 24 as a whole. Reference Figure 6As shown, the limiting guide rail 21 includes a connecting guide plate 210 that is symmetrically and spaced apart and sleeved on the supporting rotating rod 20. The connecting guide plate 210 is slidingly connected to the movable base plate 1. Guide grooves 211 are formed on both sides of the connecting guide plate 210 corresponding to the transmission belt 23. The transfer plate 24 is limited on the two connecting guide plates 210 through the driven slider 26. The same driven slider 26 is simultaneously slidably limited in the two guide grooves 211 on the same side of the two connecting guide plates 210. The two connecting guide plates 210 are spaced apart and form a sliding groove with the transmission belt 23 for the sliding of the driven slider 26. During use, the transmission belt 23 is driven to rotate and slide, which will drive the connected driven slider 26 and transfer plate 24 to slide along. During the sliding process, the driven slider 26 and transfer plate 24 will slide along the guide groove 211 on the two connecting guide plates 210, thereby limiting the sliding path of the driven slider 26 and the transfer plate 24 so that the transfer plate 24 can drive the goods thereon to rise and fall and slide in the vertical direction, so as to facilitate the staff to carry the goods.

[0047] Reference Figure 6 As shown, a guide groove is formed between the two connecting guide plates 210 and one side of the transmission belt 23 to limit the sliding path of the driven slider 26 and the transfer plate 24.

[0048] Reference Figure 6 As shown, the driven slider 26 extends outward in a "T" shape and is connected to the transfer plate 24 accordingly. The driven slider 26 is connected to the transmission belt 23 in a limited manner. The horizontal sections of the driven slider 26 are respectively limited and inserted into the two guide grooves 211 on the two connecting guide plates 210, and its vertical section extends and protrudes to the side away from the transmission belt 23 to connect to the transfer plate 24, thereby ensuring that the driven slider 26 and the connected transfer plate 24 are always driven by the transmission belt 23 to slide and lift in the vertical direction, so that the staff can move the goods.

[0049] Reference Figure 1 and Figure 2 As shown, an auxiliary plate 27 arranged obliquely is detachably connected to the movable base plate 1 to facilitate the staff in guiding the goods to be transported to move to the transfer plate 24 after being moved downward.

[0050] Example 2: Reference Figure 1 As shown, on the basis of Example 1, in order to improve the applicability to different transport vehicles, as an optional implementation method, the support rotating rod 20 is configured as a self-locking telescopic rod structure (not shown in the figure) that allows a certain telescopic sliding in the vertical direction, and in order to adapt to the telescopic adjustment of the length of the support rotating rod 20, the synchronous wheel 22 is preferably a sprocket and is respectively limited to the telescopic section and the fixed section of the telescopic rod, and the transmission belt 23 is correspondingly configured as a chain. During the process of telescopic adjustment of the support rotating rod 20, the chain links of the chain are correspondingly increased or decreased to adapt to the change in the length of the support rotating rod 20.

[0051] During work: the first step is to load goods onto the vehicle, and the staff will limit the goods to be transported on one of the transfer plates 24 located on the lower side.

[0052] Step 2: After completing the positioning of the goods, the synchronous wheel 22 and the transmission belt 23 are driven to rotate, and the transfer plates 24 connected on both sides of the transmission belt 23 are driven to rise and fall alternately, that is, the transfer plate 24 loaded with goods on one side of the transmission belt 23 moves up with the transmission belt 23, and the transfer plate 24 not loaded with goods on the other side moves down with the transmission belt 23.

[0053] Step 3: After the transfer plate 24 loaded with goods rises to the same height as the vehicle, drive the supporting rotating rod 20, the limiting guide rail 21, the synchronous wheel 22, the transmission belt 23, the transfer plate 24 and the goods to rotate as a whole, so that the transfer plate 24 loaded with goods rotates to align with the vehicle, and at the same time, the transfer plate 24 moving down on the other side rotates to align with the staff, so that the staff can move the next goods to the transfer plate 24.

[0054] Step 4: When the cargo on the vehicle needs to be unloaded, the above process of driving the transfer plates 24 on both sides of the transmission belt 23 to alternately rise and fall and driving the supporting rotating rod 20 to rotate as a whole is repeated.

[0055] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive.

[0056] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
