Description

Technical Field

[0001] The present invention relates to the technical field of transfer devices, and in particular to a storage turnover device. Background Art

[0002] Logistics warehouses, as cargo storage sites, need to receive a large amount of cargo every day. Therefore, staff need to classify and place these cargoes. Therefore, turnover devices are needed to assist in transporting cargoes. Generally, flatbed carts are used as turnover devices for transporting cargoes. Although such flatbed carts are easy to use, they are not equipped with any protective devices on their frames. Therefore, when they are pushed, cargoes can easily fall off the frames, which can easily cause the cargoes to be damaged. Moreover, some cargoes cannot be stacked (stacking can easily crush the cargoes on the lower layers), and such flatbed carts cannot realize the layered placement of cargoes. Therefore, such cargoes can only be transported in batches, which is inefficient.

[0003] In summary, the existing flatbed cart-type turnover device needs to be improved. Summary of the Invention

[0004] In view of this, an object of the present invention is to provide a storage turnover device.

[0005] In order to solve the above technical problems, the technical solution of the present invention is:

[0006] A warehouse turnover device includes a frame and rollers arranged at the bottom of the frame. The frame is a box structure with an open front side, and a plurality of horizontally arranged shelves are arranged in the frame at intervals along the height direction of the frame; railings for blocking goods are provided on the open side of the frame corresponding to the shelves; a driving mechanism is provided between the frame and the railings for driving all the railings to move simultaneously along the height direction of the frame.

[0007] Furthermore, when the driving mechanism drives the railing to move downward to a maximum stroke, the railing is flush with the shelf position.

[0008] Furthermore, the side walls on both sides of the open side of the frame are provided with sliding grooves extending along the height direction of the frame; both ends of the shelf are fixedly connected with sliders slidably connected in the two sliding grooves; the driving mechanism is connected to the slider to drive the slider to move along the height direction of the frame.

[0009] Furthermore, the driving mechanism includes a screw that is rotatably connected in the slide groove and extends along the length direction of the slide groove, and a driving member that drives the two screws to rotate simultaneously; wherein the screw threads in the two slide grooves have the same direction, and the slider is threadedly connected to the screw.

[0010] Furthermore, the driving member includes a driving shaft rotatably connected to the bottom of the frame, a turbine fixedly connected to the bottom of the screw, and a handwheel fixedly connected to one end of the driving shaft; the driving shaft has a worm section that meshes with the turbine at the corresponding turbine position.

[0011] Furthermore, a fixed handle and a movable handle are provided on the side wall of the frame adjacent to the railing, wherein the fixed wrench is fixedly connected to the side wall of the frame, and the movable handle is provided on the slider and moves synchronously with the slider, wherein when the slider moves upward to the maximum stroke, the fixed handle and the movable handle are at the same height.

[0012] Furthermore, a movable groove connected to the slide groove and extending along the height direction of the frame is opened on the side wall of the frame; a movable block movably arranged in the movable groove is fixedly connected to the side wall of the slider close to the movable groove, and the movable handle is fixedly connected to the movable block through a connecting plate.

[0024] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0025] Example:

[0026] like Figure 1 and Figure 2 As shown, this embodiment provides a storage turnover device, including a frame 1 and a roller 2 provided at the bottom of the frame 1, wherein the roller 2 can be a universal roller 2. In order to facilitate pushing and pulling the frame 1, a handle is provided on the frame 1 in this embodiment for people to hold.

[0027] In this embodiment, the frame 1 is a box structure with an open front side, which is equivalent to only one side of the frame 1 being exposed, and the other three sides can form a shielding effect.

[0028] Of course, in order to facilitate the placement of goods on the top layer, the upper end of the frame 1 can also be set to an open structure.

[0029] A plurality of horizontally arranged shelves 3 are provided in the frame 1 at intervals along the height direction of the frame 1 ; the shelves 3 are mainly used for placing goods, so that the goods can be placed in layers through the shelves 3 to prevent the problem of stacking and squeezing of the goods.

[0030] In order to prevent the goods from falling from the open side of the frame 1, in this embodiment, the open side of the frame 1 is provided with a railing 4 corresponding to the shelf 3 for blocking the goods; the so-called corresponding shelf 3 position here refers to the number of corresponding shelves 3, in other words, one shelf 3 corresponds to one railing 4; the thickness of the railing 4 does not exceed the thickness of the shelf 3 to ensure that when the railing 4 is flush with the shelf 3, its upper and lower walls will not protrude.

[0031] A driving mechanism is provided between the frame 1 and the railings 4 for driving all the railings 4 to move simultaneously in the height direction of the frame 1. In this way, when it is necessary to pick up and place goods on the frame 1, the railings 4 can be driven downward by the driving mechanism to move the pull rod to a position flush with the shelf 3. At this time, the railings 4 will not interfere with the action of picking up and placing goods.

[0032] If the railing 4 is not moved down to be flush with the shelf 3, the upper part of the railing 4 will be higher than the upper surface of the shelf 3. At this time, if the goods are pulled outward along the shelf 3 to take the goods, the railing 4 will interfere with the goods. At this time, the goods need to be lifted to a certain height (higher than the railing 4) before they can be taken out, which is relatively inconvenient. Therefore, when designing this embodiment, it is necessary to ensure that when the driving mechanism drives the railing 4 to move downward to the maximum stroke, the railing 4 is flush with the shelf 3 (the upper walls of the two are flush), so that the railing 4 will not exceed the height of the upper wall of the shelf 3, and the goods can be directly slid and pulled along the shelf 3.

[0033] In this embodiment, the side walls on both sides of the open side of the frame 1 are provided with sliding grooves 11 extending along the height direction of the frame 1; both ends of the shelf 3 are fixedly connected with sliders 5 slidingly connected in the two sliding grooves 11; the sliders 5 can move up and down along the sliding grooves 11.

[0034] The driving mechanism is connected to the slider 5 to drive the slider 5 to move along the height direction of the frame 1. Specifically:

[0035] Combine Figure 3 As shown, the drive mechanism includes a lead screw 61 rotatably connected to and extending along the length of the chute 11, and a driving member 62 that drives the two lead screws 61 to rotate simultaneously. The lead screws 61 in the two chute 11 have the same thread direction, and the slider 5 is threadedly connected to the lead screws 61. As the driving member 62 rotates the two lead screws 61, the sliders 5 on the two lead screws 61 can move up and down synchronously, thereby achieving the purpose of raising and lowering the railing 4. When the slider 5 slides until it contacts the bottom wall of the chute 11, the railing 4 is now flush with the shelf 3.

[0036] The drive member 62 comprises a drive shaft 621 rotatably connected to the bottom of the vehicle frame 1, a worm gear 622 fixedly connected to the bottom of the lead screw 61, and a handwheel 623 fixedly connected to one end of the drive shaft 621. A worm segment meshes with the worm gear 622 at a position corresponding to the worm gear 622 on the drive shaft 621. Rotating the handwheel 623 drives the drive shaft 621 to rotate, and the worm segment and worm gear 622 cooperate to drive the two lead screws 61 to rotate synchronously, thereby raising and lowering the handrail 4.

[0037] Since in actual use, sometimes some workers forget to raise the railing 4 after loading the goods into the frame 1, so that the goods cannot be protected, making the railing 4 useless. Therefore, in order to avoid this problem, in this embodiment:

[0038] The handle includes a movable handle 8 and a fixed handle 7. Specifically: Figure 4 and Figure 5As shown, a fixed handle 7 and a movable handle 8 are provided on the side wall of the frame 1 adjacent to the railing 4, wherein the fixed wrench is fixedly connected to the side wall of the frame 1, and the movable handle 8 is provided on the slider 5 (the uppermost slider 5) and moves synchronously with the slider 5, wherein when the slider 5 moves upward to the maximum stroke (the slider 5 contacts the top wall of the slide groove 11), the fixed handle 7 and the movable handle 8 are located at the same height.

[0039] Through the above arrangement, the slider 5 and the movable handle 8 can move synchronously. When the railing 4 is not raised, the slider 5 connected to the movable handle 8 is in a lower position, that is, the fixed wrench and the movable handle 8 are not in the same horizontal position, and there is a height difference between the two. In this way, when the staff holds the two handles, they will obviously feel the height difference, which reminds the staff that the railing 4 is not raised. When the railing 4 is raised, the two handles will be at the same height position, so they can be easily grasped.

[0040] In this embodiment, a movable groove 12 is provided on the side wall of the frame 1, which is connected to the slide groove 11 and extends along the height direction of the frame 1; a movable block 9 is fixedly connected to the side wall of the slider 5 close to the movable groove 12 and movably penetrates into the movable groove 12, wherein the movable handle 8 is fixedly connected to the movable block 9 through a connecting plate 91, and the connecting plate 91 is provided on the side wall of the frame 1 and can be moved up and down along the side wall of the frame 1. When the slider 5 moves up and down, it will drive the movable block 9 to move up and down along the movable groove 12, and then drive the connecting plate 91 to move up and down, and finally achieve the purpose of driving the movable handle 8 to move up and down. It can be seen that the driving mechanism in this embodiment has two functions. First, it is used to drive the railing 4 to move and achieve the effect of lifting and lowering the railing 4; second, it is used for the movement of the movable handle 8 at the same time, so that the handle moves although the railing 4 moves, to remind the staff to raise the railing 4 before transporting the goods.

[0041] Implementation principle:

[0042] Before placing the goods, first rotate the handwheel 623 to drive the drive shaft 621 to rotate, and then drive the slider 5 to move, so that the slider 5 drives the railing 4 to move downward, so that the railing 4 is flush with the shelf 3. At this time, there is no interference from the railing 4, and the goods can be placed on the shelf 3.

[0043] After all the goods have been placed, the drive shaft 621 is reversed to raise the railing 4 to cover the goods, and then the transportation can begin.

[0044] The above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
