Description

Technical Field

[0001] This utility model relates to the field of shelf bases, and more specifically, to an assembled double-depth shelf base. Background Technology

[0002] Double-depth racking is a type of warehouse racking system that uses a double-row side-by-side storage structure. It increases storage density by reducing aisle space and is mainly used for storing standardized palletized goods. Compared with traditional single-depth racking, double-depth racking saves more than 50% of aisle space, significantly increasing warehouse storage capacity. Since double-depth racking requires the use of double-depth forklifts, and double-depth forklifts usually have longer forks, a base needs to be installed at the bottom of the racking to leave space at the bottom of the racking, which facilitates forklift movement.

[0003] However, most double-depth rack bases currently have the following problems:

[0004] 1. Existing double-depth rack bases are mostly spliced ​​and fixed to the supporting steel frame by bolts or welding. If transportation and disassembly are required, it is relatively troublesome and inconvenient to conveniently splice and install the base and supporting steel frame.

[0005] Second, in the existing double-depth rack base, the equipment is mostly installed on the ground using bolts. After installation, the bolts are exposed to the outside, and dust on the ground and moisture in the air can easily affect the bolts, causing them to rust and making it inconvenient to protect them.

[0006] Therefore, we have made improvements to this by proposing a modular double-depth shelf base. Utility Model Content

[0007] The purpose of this utility model is to address the current problems of inconvenience in easily assembling and installing the base and the supporting steel frame, as well as the inconvenience in protecting the installation bolts.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] Assembled double-depth rack bases are used to improve the above-mentioned problems.

[0010] The application is as follows:

[0011] The system includes a supporting steel frame, a splicing frame fixedly connected to the supporting steel frame, a bidirectional threaded rod rotatably connected to the supporting steel frame, a turntable fixedly connected to the bidirectional threaded rod, a connecting plate threadedly connected to the bidirectional threaded rod, a clamping plate fixedly connected to the connecting plate, a support base provided on the supporting steel frame, a positioning bolt threadedly connected to the support base, a protective cover provided on the support base, a sealing gasket fixedly connected to the protective cover, a positioning block fixedly connected to the protective cover, an installation box fixedly connected to the support base, a sliding groove provided on the installation box, a spring provided inside the installation box, a limit plate fixedly connected to the other end of the spring, a clamping block fixedly connected to the limit plate, and a pressing plate fixedly connected to the limit plate.

[0012] As a preferred technical solution of this application, the splicing frame is symmetrically distributed on the left and right sides of the top of the supporting steel frame, and the end of the bidirectional threaded rod is fixedly connected to the center of one side of the turntable.

[0013] As a preferred technical solution of this application, the connecting plates are symmetrically distributed on the left and right sides of the bidirectional threaded rod, and the side end face of the connecting plate is in contact with the inner side of the supporting steel frame.

[0014] As a preferred technical solution of this application, the positioning bolts are symmetrically distributed on the left and right sides of the support base, and the positioning bolts correspond one-to-one with the sealing gaskets through the protective covers.

[0015] As a preferred technical solution of this application, the limiting plates are symmetrically distributed on the left and right sides of the spring, and the limiting plates correspond one-to-one with the squeezing plates through the locking blocks.

[0016] As a preferred technical solution of this application, the positioning block has a "T" shaped cross-section, and the card block has an isosceles triangle cross-section.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] In the scheme of this application:

[0019] 1. Equipped with a bidirectional threaded rod; when separating the supporting steel frame from the support base, the turntable can be rotated to drive the bidirectional threaded rod to rotate. The bidirectional threaded rod can drive the connecting plates on both sides to move inward. At the same time, the clamping plate on the connecting plate can disengage from the clamping groove of the support base. The support base can be separated and removed from the connecting plate without obstruction. If one end of the support base is damaged, it can be disassembled and replaced.

[0020] 2. A protective cover is provided; when protecting the positioning bolts used to connect the support base to the ground, the protective cover can be placed over the positioning bolts, and the positioning block on the protective cover can slide and engage in the groove of the mounting box. When sliding, the positioning block can push the inclined surface of the locking block to move the locking block and the limiting plate. The limiting plate can compress the spring, and under the push of the spring, the limiting plate and the locking block are engaged in the positioning block of the protective cover, which can play a role in limiting and fixing. The sealing gasket on the protective cover can fit and seal on the support base, fully protecting the positioning bolts. Attached Figure Description
