[0002] Forklifts such as electric forklifts, manual forklifts and stacker forklifts are commonly used in the logistics industry to transport and organize pallets. When in use, the forks carried by them are inserted into the holes of the pallet, and the forks are raised and lowered by the driving hydraulic system, and the pallet handling operation is completed by power movement. They play a very important role in the logistics system of enterprises and are the main force in pallet handling equipment.

[0003] However, in the prior art, forklift tools such as electric forklifts, manual forklifts, and stacker forklifts require sufficient work site space, safe distances, and storage locations. In workplaces with small site space, small passage space, frequent personnel activities, and faster pallet cleaning, forklift tools such as electric forklifts, manual forklifts, and stacker forklifts have poor flexibility, maneuverability, and convenience, and are inconvenient to use. For example, in some cigarette sorting and stocking out work areas, due to limited space and timely replenishment, the pallets must be cleared out of the work area as soon as the cigarettes they carry are emptied to make room for timely replenishment, but the work area is not convenient for storing larger tools such as forklift tools, and a single person cannot carry and transfer tools such as forklifts by hand, which makes the use of forklift-type logistics tools extremely inconvenient. Therefore, there is a need for a tool that is easy to store on-site, safe and flexible to operate, has a small work space, and can assist a single person in quickly transferring and transporting pallets.

[0025] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a preferred embodiment of the utility model provides a pallet transfer device, which includes a vehicle body 1 for carrying a pallet 3 and a clamping mechanism 2 for fixing the pallet 3;

[0027] The clamping mechanism 2 includes a clamping body 21 and a locking device 22 which are arranged relatively on the side of the vehicle body 1 along direction A; the clamping body 21 is rotatably connected to the vehicle body 1, and a clamping block 211 is provided on the top of the clamping body 21 for being inserted into a groove 31 on the side of the tray 3 to fix the tray 3; the locking device 22 includes a locking spring 221 and a limiting groove 222 provided on the vehicle body 1, one end of the locking spring 221 is fixedly connected to a side of the clamping body 21 close to the tray 3, and the other end of the locking spring 221 is slidably connected to the limiting groove 222 to pull the top of the clamping body 21 to rotate in a direction close to the tray 3, and to make the clamping block 211 be engaged in the groove 31 on the side of the tray 3.

[0028] Specifically, traditional forklifts and other equipment have poor flexibility and cannot meet the need for quickly transferring pallets 3 in a small space. When transferring pallets 3, the utility model first stacks multiple pallets 3 and places them on the vehicle body 1, so that the groove 31 on the side of the pallet 3 is opposite to the block 211 on the top of the clamping body 21, and then adjusts the position of the end of the locking spring 221 in the limit groove 222 and limits it, so that the locking spring 221 is taut and continuously applies tension to the clamping body 21, and the block 211 on the top of the clamping body 21 can be continuously and stably stuck in the groove 31 of the pallet 3, thereby realizing rapid fixation of the pallet 3. When the pallet 3 is fixed, the vehicle body 1 can be pushed to move to transfer the pallet 3. It has stronger flexibility and is more suitable for the need to quickly transfer pallets 3 in a small space. In one embodiment, the tray 3 is placed vertically on the vehicle body 1 and then stacked, in which case the groove 31 on the tray 3 extends horizontally, and the corresponding block 211 also extends horizontally; in other embodiments, the tray 3 is stacked horizontally, in which case the groove 31 on the tray 3 extends vertically, and two grooves 31 can also be provided on each side of the tray 3, and the corresponding block 211 also extends vertically. How the trays 3 are stacked should be within the protection scope of the present utility model.

[0029] In some embodiments, the clamping body 21 includes two clamping arms 212 correspondingly arranged on the side of the vehicle body 1 along the B direction, and the tops of the two clamping arms 212 are connected by a clamping plate 213; a clamping block 211 is fixed on the surface of the clamping plate 213 facing the other clamping plate 213;

[0030] The B direction is perpendicular to the A direction.

[0031] Specifically, in one embodiment, direction A is consistent with the moving direction of the vehicle body 1, that is, the two clamping bodies 21 are respectively arranged on the front and rear sides of the vehicle body 1, and direction B is the left and right sides of the vehicle body 1, that is, the two clamping arms 212 in the same clamping body 21 are respectively arranged on the left and right sides of the vehicle body 1; in another embodiment, direction A and direction B can also be interchanged. At this time, the plate surface of the tray 3 faces the pusher, that is, the tray 3 is stacked along the front and rear direction of the vehicle body 1, the clamping bodies 21 are respectively arranged on the left and right sides of the vehicle body 1, and the clamping arms 212 in the same clamping body 21 are respectively arranged on the front and rear sides of the vehicle body 1.

[0032] In addition, when the trays 3 are stacked horizontally, the clamping plate 213 is no longer required between the two clamping arms 212 in the same clamping body 21. Instead, it is only necessary to set a clamping block 211 extending in the vertical direction corresponding to the groove 31. The two clamping arms 212 are connected by a rotating shaft 214 and rotate synchronously.

[0033] In some embodiments, the clamping body 21 includes a rotating shaft 214 , two ends of which pass through the vehicle body 1 and connect to the middle parts of the two clamping arms 212 ; a bearing is provided between the rotating shaft 214 and the vehicle body 1 .

[0034] Specifically, the rotating shaft 214 enables the two clamping arms 212 to rotate synchronously, so as to better clamp the tray 3; the setting of the bearing enables the rotating shaft 214 to better rotate in the through hole on the vehicle body 1, and will not be blocked and cause the problem of difficulty in rotation. In another embodiment, the clamping arms 212 are rotatably connected to the vehicle body 1 through the rotating shaft 214, rather than through a whole rotating shaft 214.

[0035] In some embodiments, the clamping mechanism 2 also includes a return spring 23, one end of the return spring 23 is connected to the bottom end of the clamping arm 212, and the other end of the return spring 23 is connected to the vehicle body 1, and the return spring 23 is used to pull the bottom end of the clamping arm 212 to rotate the top of the clamping arm 212 away from the tray 3.

[0036] Specifically, since the locking spring 221 is tightened during the clamping process of the tray 3, the block 211 on the top of the clamping body 21 is rotated toward the tray 3 and stuck in the groove 31. At this time, the bottom end of the clamping arm 212 is rotated in the direction away from the vehicle body 1, thereby applying a force to the reset spring 23, so that the reset spring 23 is in a stretched state; when it is necessary to release the clamping of the tray 3, the end of the locking spring 221 is first loosened to allow the end of the locking spring 221 to slide in the limit groove 222. At this time, the bottom end of the clamping arm 212 is reset and rotated under the pulling force of the reset spring 23, thereby driving the block 211 on the top of the clamping arm 212 to rotate in the direction away from the tray 3, and the block 211 is separated from the groove 31 to completely release the binding clamping of the tray 3.

[0037] In some embodiments, the top and bottom surfaces of the clamping block 211 are both inclined surfaces 2111. Specifically, the groove 31 of the tray 3 is also provided with an inclined surface corresponding to the inclined surface 2111 on the clamping block 211. In the process of clamping the tray 3, the locking spring 221 pulls the top clamping block 211 of the clamping body 21 toward the tray 3, and the clamping block 211 also moves downward at the same time. At this time, the clamping block 211 with the inclined surface 2111 on the ground can better fit into the groove 31 to clamp the tray 3; and when the tray 3 needs to be released, the inclined surface 2111 on the top of the clamping block 211 makes it easier for the clamping block 211 to slide out of the groove 31 and detach from the tray 3.

[0038] In some embodiments, the bottom surface of the block 211 is provided with an anti-skid pad layer 2112. Specifically, the anti-skid pad layer 2112 can increase the friction between the block 211 and the inner wall of the groove 31 of the tray 3, ensure the stability of the clamping body 21 clamping the tray 3, and prevent the tray 3 from escaping from the groove 31.

[0039] In some embodiments, the limiting groove 222 includes a sliding groove 2221 and a clamping groove 2222. The sliding groove 2221 is connected to the bottom of the clamping groove 2222 and is V-shaped. The inner wall of the clamping groove 2222 is evenly distributed with a plurality of positioning grooves 2223.

[0040] The end of the locking spring 221 away from the tray 3 is connected to a slider 223, and the slider 223 slides in the slide groove 2221 and the card slot 2222; the slider 223 is provided with a protruding positioning block 2231 corresponding to the positioning slot 2223, and the positioning block 2231 is inserted into the positioning slot 2223 to limit the position of the slider 223 in the slide groove 2221.

[0041] Specifically, the slot 2222 is on the side of the slide slot 2221 away from the clamping arm 212, and the end of the locking spring 221 away from the clamping arm 212 is connected to the slider 223, and the slider 223 slides in the V-shaped limit slot 222. When it is necessary to clamp the added tray 3, the slider 223 is slid from the slide slot 2221 to the slot 2222, thereby driving the clamping arm 212 to rotate, and the block 211 is inserted into the groove 31. Then, by inserting the positioning block 2231 into the positioning slot 2223, the slider 223 is prevented from sliding down and re-entering the slide slot 2221 under the action of the locking spring 221, thereby ensuring that the clamping body 21 stably clamps the tray 3.

[0042] In some embodiments, a through slot 2224 is provided at the bottom of the limiting slot 222, a bolt 2225 is connected to the bottom surface of the slider 223, and the other end of the bolt 2225 passes through the through slot 2224 and is connected to a limiting nut. Specifically, the bolt 2225 and the limiting nut are provided to limit the slider 223 in the limiting slot 222 to prevent the slider 223 from being separated from the limiting slot 222 during the sliding process.

[0043] In some embodiments, the slider 223 is fixedly connected to a pedal rod 2232, and a pedal 2233 is provided at the end of the pedal rod 2232 away from the slider 223. Specifically, in actual use, the user can push the slider 223 to slide in the slide groove 2221 and the clamping groove 2222 by stepping on the pedal, and adjust the position of the slider 223 in the limiting groove 222, avoiding bending over to manually adjust the position of the slider 223, and further improving the transfer efficiency of the tray 3.

[0044] In summary, the embodiment of the utility model provides a pallet 3 transfer device. When the pallet 3 needs to be transported and transferred, the pallet 3 is first stacked on the vehicle body 1, and then the pedal 2233 is driven by the foot to make the slider 223 slide in the slide groove 2221 toward the direction of the clamping groove 2222 and stretch the clamping arm 212 to drive the top of the clamping arm 212 to rotate toward the pallet 3. When the slider 223 enters the slide groove 2221, the clamping block 211 has also entered the groove 31 to clamp the pallet 3. After adjusting the position of the slider 223, the pedal is released, the locking spring 221 drives the sliding movement, and the positioning block 2231 is clamped into the positioning groove 2223. The position of the slider 223 is restricted to ensure that the clamping arm 212 stably clamps the tray 3; when the tray 3 needs to be unloaded, the slider 223 is also driven by the leg to make the positioning block 2231 disengage from the positioning groove 2223, the slider 223 moves downward along the card slot 2222, and the slider 223 is adjusted to enter the slide groove 2221, and then the pedal 2233 is released, the locking spring 221 is restored, the clamping arm 212 releases the clamping of the tray 3, and the reset spring 23 pulls the clamping arm 212 to rotate, so that the top of the clamping arm 212 is away from the tray 3, and the card block 211 is disengaged from the groove 31, that is, the tray 3 is unlocked, and the tray 3 is convenient to unload.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
