Abstract
Description
Technical Field

[0002] "Food security is of great significance to the country", which is the "ballast stone" related to the national economy and people's livelihood, related to social stability and economic development, and is an important foundation for maintaining national security.
[0003] At present, the grain surface walkway boards on the market are mainly hollowed-out grain surface walkway boards, which are made of PE plastic that is not easy to age. The products are beautiful, light and durable. There are dense holes on the board, which have good air permeability. The holes extend downward to form barrier tubes, so that the grain will not rise from the air holes to the board surface; the lower surface of the board is designed as a grille. When laid on the grain surface and stepped on, the grille will sink into the grain surface to generate buoyancy. When the staff walks on it, the walkway board will not move, and the holes will make the walkway board ventilate up and down, which can effectively control the mildew and deterioration of the grain under the board surface. However, in the process of laying and recycling, all work needs to be carried out manually, and the efficiency is not high.
[0004] In the process of storing grain in granaries in our country, in order to facilitate the operators to walk and check the quality of the grain in the granary or carry out operations in the granary, it is usually necessary to lay a walkway board on the grain pile. Before the grain is put into or taken out of the granary, manual laying or recycling is generally required again. Therefore, there is an urgent need to design a grain surface walkway board that does not require manual handling and laying, which can improve work efficiency and reduce the labor intensity of operations.

[0027] It should be noted that the application scenario is as follows: The user stacks and assembles the corresponding number of walkway boards according to the size of the warehouse and places them at a suitable position in the warehouse. When laying is required, the operator applies a thrust to the upper walkway board to quickly complete the paving of the walkway board, improving the operation efficiency. When the walkway board needs to be recycled during the warehousing and outbound operations, the operator can insert a long rod tool with a hook into the long round hole of the uppermost walkway board and apply a pulling force to quickly recycle multiple walkway board components along the slide rail. After recycling and stacking, the long rod tool is inserted into the long round holes of each layer of walkway board or tied with a hemp rope for simple fixation to prevent the walkway board from self-sliding. This retractable grain surface walkway board adopts a modular design concept and can be quickly disassembled and assembled, including: a walkway board and a slide rail assembly.
[0028] An embodiment of the present application provides a retractable grain surface walkway board. Figure 1 For a schematic diagram of a retractable grain surface walkway board structure, as Figure 1 shown, the grain surface walkway board includes: a slide rail assembly 2 and a walkway board 1. The slide rail assembly 2 is fixedly located on both sides of the walkway board 1. The slide rail assembly 2 can connect and stack and assemble multiple walkway boards 1.
[0029] Preferably, Figure 2Schematic structural diagram of a slide rail assembly provided by an embodiment of the present application, as Figure 2 shown, the slide rail assembly 2 includes: a mixing wheel 201 and a slide rail 203.
[0030] Preferably, Figure 3 Schematic structural diagram of an up-and-down stacking structure of a walkway board provided by an embodiment of the present application, as Figure 3 and Figure 2 shown, the pulley 201 of the upper-layer slide rail assembly 2 of the walkway board 1 after stacking is located on the slide rail 203 of the lower-layer slide rail assembly 2.
[0031] Preferably, as Figure 1 shown, the board surface of the walkway board 1 is a mesh structure.
[0032] Preferably, as Figure 2 shown, the front end of the slide rail assembly 2 includes: a stepped screw 204, a limit hook 205, and a torsion spring 206. Among them, the stepped screw 204 exists only in the limit mechanism at the front end of the slide rail assembly 2.
[0033] Preferably, as Figure 2 shown, the stepped screw 204, the limit hook 205, and the torsion spring 206 in the front end of the slide rail assembly 2 form a limit mechanism, that is, the limit mechanism is a limit combination.
[0034] Preferably, as Figure 2 shown, the torsion spring 206 is elastically connected to the limit hook 205. The stepped screw 204 is fixedly connected to the limit hook 205.
[0035] Preferably, as Figure 3 shown for the walkway board in the up-and-down stacked state and Figure 2 shown, the stepped screw 202 at the rear end of the upper-layer slide rail assembly 2 of the walkway board 1 after stacking is meshed with the limit hook 205 at the front end of the lower-layer slide rail assembly at the maximum extended stroke.
[0036] Preferably, as Figure 2 shown, a limit plate is provided at the rear end of the slide rail assembly 2.
[0037] Preferably, as Figure 2 and Figure 3 shown, the limit plate is a limit for preventing the pulley at the minimum extended stroke. That is, it is used to prevent the stacked walkway board 1 from sliding out of the slide rail 203 of the slide rail assembly 2.
[0038] As a feasible implementation manner, as Figure 3As shown in the figure, the slide rail assembly 2 is fixed to both sides of the walkway board 1 with screws to form a walkway board assembly. Multiple walkway board assemblies are stacked and assembled so that the pulleys 201 of the upper walkway board assembly slide on the slide rails 202 of the lower walkway board assembly. The walkway board 1 is provided with oblong through holes. Operators can insert a long hook rod tool into the oblong holes or mesh holes of the topmost walkway board and apply pulling or pushing force, so that multiple walkway board assemblies can move telescopically along the slide rails. The walkway board 1 is designed with mesh holes, so that there is a certain distance between the walkway board 1 and the grain surface, which is convenient for air circulation and prevents grain from breeding eggs due to airtightness.
[0039] As a feasible implementation manner, the front end of the slide rail assembly 2 is provided with a limit mechanism composed of a step screw 204, a limit hook 205, and a torsion spring 206. When the upper walkway board assembly extends forward to the maximum stroke, the limit hook 205 in the lower walkway board assembly will engage with the step screw 202 at the rear end of the sliding assembly 2 in the upper walkway board assembly to prevent the upper walkway board from sliding out of the track. There is a limit plate at the end of the slide rail 203, which can also prevent the upper walkway board assembly from sliding out of the track when it retracts to the minimum stroke.
[0040] The embodiment of the present application can realize automatic stacking through a designed telescopic grain surface walkway board: the telescopic grain surface walkway board can be neatly stacked and placed when not in use, without occupying space. High work efficiency: By pushing or pulling the upper walkway board by personnel, automatic laying or recycling can be completed.
