Description

Technical Field

[0001] This utility model belongs to the field of raw fetus storage technology, specifically relating to a storage vehicle for raw fetuses laid flat. Background Technology

[0002] During the manufacturing process of automobile tires, there is a process of combining various semi-finished rubber products into an uncured tire shape. At this stage, the tire precursor is called a green tire, which needs to be vulcanized before it can be installed on the automobile rim to realize its function.

[0003] During the vulcanization process, there is a storage period, generally 8 to 24 hours, during which the green tires are stored in green tire carts or warehouses. Currently, some factories store green tires vertically in green tire storage carts, with the tread facing downwards along the circumference, such as the green tire storage cart disclosed in CN218313489U and the tire blank storage cart disclosed in CN203460909U. However, this storage method can easily cause the tire bead to become elliptical, resulting in a certain difference in horizontal and vertical diameters from the design dimensions. Furthermore, the deformation of the green tire is not conducive to the alignment control during subsequent vulcanization.

[0004] Therefore, there is a need to develop a storage vehicle that allows the green tires to be laid flat in order to reduce their deformation. Utility Model Content

[0005] The purpose of this utility model is to provide a storage cart for laying green tires flat in order to solve at least one of the above problems. This solves the problem that the existing storage carts for green tires laid vertically will cause large deformation of the green tires. This solution realizes the flat laying of green tires, and this storage cart can facilitate the loading and unloading of green tires.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A storage vehicle for laying out green tires flat includes a vehicle body, a support frame, and a support base;

[0008] The vehicle body is provided with several layers of support frames, and the bottom support frame is fixedly connected to the vehicle body, while the remaining support frames are movably connected to the vehicle body; the bottom of the vehicle body is connected to rollers.

[0009] The support base includes a support portion disposed on a support frame; a tray is disposed at the center of the support portion, and the support portion is used to lay the green embryo flat.

[0010] Preferably, the tray is a frustum structure with the top and bottom surfaces connected.

[0011] Preferably, the support frame includes an outer frame and a support rod connected inside the outer frame; the outer frame is rectangular, the support rod is arranged parallel to the short side of the outer frame, and the support seat is disposed on the support frame formed by the outer frame and the support rod.

[0012] Preferably, the support frame further includes a limiting rod connecting the outer frame and the support rod; the limiting rod is located at the four corners of the support frame, forming an octagonal support structure inscribed within the support frame.

[0013] Preferably, one side of the non-bottom support frame is connected to the rotating shaft, and the rotating shaft is rotatably connected to the vehicle body.

[0014] Preferably, a torsion spring connects the non-bottom support frame to the vehicle body.

[0015] Preferably, the non-bottom support frame is connected to the vehicle body by a cylinder or electric cylinder.

[0016] Preferably, the rotating shaft is connected to the vehicle body via a lug plate.

[0017] Preferably, the vehicle body is equipped with handles.

[0018] Preferably, the roller is a swivel wheel.

[0019] The working principle of this utility model is as follows:

[0020] When in use, the storage vehicle can lay the green tires flat from the bottom to the top layer, and can also remove the green tires from the top to the bottom layer. When placing the green tires on the bottom layer, the top layer can be flipped up, and after removing the green tires from the top layer, the top layer can be flipped up again to provide more operating space.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] Storing green tires flat minimizes deformation due to gravity. Based on this, this solution proposes a storage cart for flat-laying green tires. This cart, through the coordinated arrangement of support seats and support frames, enables the flat storage of multiple layers of green tires on a single cart. This reduces deformation and improves space utilization and storage / transfer efficiency. Simultaneously, the rotatable support frames provide greater operating space during loading and unloading, facilitating worker operations and reducing the risk of collisions.

[0023] The swivel casters and handles make it easy to push, pull, and move the storage cart. Attached Figure Description

[0033] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0034] Example

[0035] A storage vehicle for laying out raw fetuses flat, such as Figure 1-8 As shown, it includes a vehicle body 1, a support frame 2, and a support base 3;

[0036] The vehicle body 1 is provided with several layers of support frames 2, and the bottom support frame 2 is fixedly connected to the vehicle body 1, while the remaining support frames 2 are movably connected to the vehicle body 1; the bottom of the vehicle body 1 is connected to rollers.

[0037] The support base 3 includes a support portion disposed on the support frame 2; a tray 32 is disposed at the center of the support portion, and the support portion is used to lay the green tire flat.

[0038] More specifically, in this embodiment:

[0039] like Figure 1-3 As shown, the vehicle body 1 is constructed from welded square tubing, with rollers at the four corners of its bottom, which can be casters. Handles 5 can also be installed in the middle of both sides for easy pushing and pulling.

[0040] The bottom surface, the back surface, and the two side surfaces of the vehicle body 1 form a rectangular frame, and the front surface and the top surface are of an open structure; moreover, intermediate square tubes for strengthening the structural strength are provided on the back surface and the two side surfaces of the vehicle body 1. Among them, since the side surface is relatively narrow, only one square tube can be horizontally welded to form a "day" shape. Since the back surface is relatively wide, one square tube can be horizontally and vertically welded respectively to form a "field" shape, and a reinforcing steel plate is also welded at the central intersection of the "field" - shaped structure to further enhance the structural strength. In other embodiments, the number of horizontally and vertically welded square tubes and reinforcing steel plates can be further increased according to the size of the vehicle body 1. In addition, a support portion 31 extending horizontally along the length direction is provided on the square tube at the front of the side surface to support the support frame 2; and, an ear plate is provided on the square tube at the back of the side surface along the length direction to connect to the rotating shaft 4; the positions of the support portion 31 and the ear plate are arranged corresponding to each other so that the support frame 2 connected and supported thereon can be placed horizontally.

[0041] The support frame 2, as Figure 4-6 shown, is a rectangular frame, and its width and length are slightly smaller than the width and length of the vehicle body 1 so as to be able to rotate and move within the vehicle body 1. The bottom - layer support frame 2 is directly and horizontally welded and fixed inside the vehicle body 1. One side surface (long side) of the support frames 2 of the remaining layers is fixedly connected to the rotating shaft 4 (round tube), and the rotating shaft 4 is further rotatably connected to the vehicle body 1 through an ear plate. Furthermore, these support frames 2 can rotate around the rotating shaft 4 to achieve turning up or laying flat. In this embodiment, a total of four layers of support frames 2 are provided. Among them, the bottom - layer support frame 2 is directly welded and fixed to the vehicle body 1, and the support frames 2 of the upper three layers are all connected to the vehicle body 1 through the rotating shaft 4.

[0042] The support frame 2 can be further divided into an outer frame 21, support rods 22, and limiting rods 23. The outer frame 21 is directly connected to the rotating shaft 4. The support rods 22 are evenly spaced across the two long sides of the outer frame 21 and are parallel to the short sides of the outer frame 21, dividing the outer frame 21 into multiple spaces for supporting the support base 3 to hold the green tire. At this time, the outer frame 21 and the support rods 22 together constitute the support frame for supporting the support base 3. Furthermore, limiting rods 23 are also provided at an angle of 45° between adjacent outer frames 21 and support rods 22, that is, at the four corners of the support frame, to form an octagonal support structure inscribed inside the rectangular support frame, which can provide more stable support for the support base 3 and improve the structural strength to cope with the use of green tires with larger weights. In addition, reinforcing angle plates (such as stiffening plates) can be welded at the corners of the outer frame 21 and at the connection between the outer frame 21 and the support rods 22 to improve the overall structural strength. In this embodiment, two support rods 22 are installed inside the outer frame 21 to divide the single-layer support frame 2 into three spaces for placing green tires. When the support frame 2 is laid flat, one long side is connected to the vehicle body 1 via a rotating shaft 4, and the other long side rests on a horizontally extending support part 31 on the vehicle body 1 to keep the support frame 2 horizontal. In this embodiment, the vehicle body 1 and the support frame 2 are connected by a torsion spring. In use, manual force is applied to flip the support frame 2 upward, and the weight of the green tire helps maintain the horizontal state of the support frame 2. In other embodiments, a power structure such as a cylinder or electric cylinder can be used to rotately connect the vehicle body 1 and the support frame 2, so that the upward and horizontal placement of the support frame 2 can be achieved by pushing and pulling the power structure, reducing manual intervention and avoiding the risk of pinching hands.

[0043] Support 3, such as Figure 7 , 8 As shown, it includes a rectangular support (support 31). A recessed tray 32 is located at the center of this support. The tray 32 has a frustum-shaped structure and no top or bottom surface. The tray 32 is a continuous structure (i.e., only the side walls of the frustum are present), which matches the shape of the green tire's side surface, accommodating and supporting it. This support can be assembled to the support frame 2 (including the outer frame 21, support rod 22, and limiting rod 23) using screws or rivets to ensure a reliable connection during the rotation of the support frame 2 and prevent it from falling off. In use, the green tire is placed flat on the support, and the tray 32 precisely accommodates and supports the protruding side portion of the green tire.

[0044] When loading green tires into this storage cart, the green tires are placed flat in the support base 3 from the bottom to the top. After each layer is placed, the upper support frame 2 is laid flat, and green tires are placed flat in the support base 3 again. This continues until all the green tires in the batch are placed, or the storage cart is full. Then, the storage cart is pushed to the designated location for storage. When unloading green tires from this storage cart, the green tires are removed from the top to the bottom. After each layer of green tires is completely removed, the support frame 2 for that layer is flipped up, and the next layer of green tires is removed. This continues until all green tires are removed.

[0045] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
