Description

Technical Field

[0001] The utility model relates to the field of warehousing and logistics, in particular to a multi-layer drawer-type steel plate shelf. Background Art

[0002] The steel production process requires a large number of steel plates of varying specifications. Steel plate racking is used to address the issue of stacking and storing these plates, eliminating the need for more storage space. Standardized stacking of steel plates on racks also helps avoid potential safety hazards associated with irregular stacking.

[0003] Traditional steel plate racking is primarily based on beam-type racking, which has advantages such as a wide range of applications. However, traditional beam-type racking can only store relatively small cargo weights and sizes, making it difficult to stack and store large and heavy steel plates. Furthermore, access to heavy steel plates after storage can be difficult. Utility Model Content

[0004] In response to the problems that traditional beam steel plate shelves have general bearing strength and are difficult to store and retrieve heavy objects, the utility model proposes a multi-layer drawer-type steel plate shelf. A cargo drawer driven by a motor is set in the high-strength vertical steel structure. While ensuring the overall strength of the shelf, it also facilitates the storage and retrieval of heavy steel plates. At the same time, a limit switch is set on the vertical steel structure to prevent the cargo drawer from over-operating.

[0005] The technical solution adopted by this utility model is:

[0006] A multi-layer drawer-type steel plate shelf, comprising:

[0007] A vertical steel structure comprising four columns and a plurality of supporting beams, with tracks provided on the beams;

[0008] The cargo drawer is installed on the supporting beam of the vertical steel structure. Each cargo drawer includes a load-bearing truss and two carrying trolleys, including:

[0009] The load-bearing truss is used to place the steel plates and connect the two transport trolleys into one;

[0010] The transport trolleys are arranged on both sides of the load-bearing trusses. The transport trolleys are driven by motors and the motors of the transport trolleys on both sides run synchronously. The motors are reduction motors integrated with reduction gears. When the motors drive the transport trolleys on both sides to move, the transport trolleys can cooperate with the rails to drive the cargo drawers to move on the crossbeams of the vertical steel structure.

[0011] A travel limit device is also provided on the column of the vertical steel structure. When the transport trolley moves to the end of the track, the travel limit device will disconnect the operating current of the transport trolley to stop the transport trolley from running.

[0012] The transport trolley includes a driving wheel set and a driven wheel set, and the driving wheel set drives the driven wheel set to operate together with the power provided by the reduction motor.

[0013] The transport trolley further comprises a trolley crossbeam, which is used to mount the driving wheel set and the driven wheel set, and a U-shaped groove is provided on the trolley crossbeam.

[0014] The transport trolley is also provided with a buffer block, which is used to absorb the power generated when the transport trolley stops running.

[0015] The stroke limiting device is provided with a roller rotating arm.

[0016] The vertical steel structure is also provided with a connecting beam.

[0017] The area of ​​the cargo drawer is half of the horizontal area of ​​the vertical steel structure.

[0018] The beneficial effects of the present invention are as follows: through the arrangement of high-strength vertical steel structure and cargo drawers, the shelf as a whole can carry more heavy-weight steel plate cargo; the arrangement of an electric-driven transport trolley on the cargo drawer facilitates the storage and retrieval of cargo; the reduction motor and travel limit device ensure that the transport trolley will not over-run, thereby improving the stability of the steel plate transportation process.

[0030] The structure, specific features, usage methods and main effects of the utility model are comprehensively described below with reference to the accompanying drawings.

[0031] like Figures 1 to 4 , a multi-layer drawer type steel plate shelf, including a vertical steel structure 1 and a cargo drawer 2. Figure 5 、 Figure 6 The vertical steel structure 1 includes four columns 11 and several supporting beams 12. The overall frame of the vertical steel structure 1 is made of section steel. Among them, the four columns 11 are made of H-shaped steel. As a preferred embodiment of the present invention, the supporting beams 12 are also made of H-shaped steel. The use of section steel, especially H-shaped steel, makes the vertical steel structure 1 stronger and can bear a greater weight. The supporting beams 12 are arranged on the side direction of the vertical steel structure 1, and rails 13 are welded to the supporting beams 12. The rails 13 are made of steel plates with moderate strength. The rails 13 made of steel plates have the advantages of easy processing and replacement. Several connecting beams 14 are welded on the front direction of the vertical steel structure 1. The connecting beams 14 are used to connect the columns 11 horizontally, so that the vertical steel structure 1 forms an integral steel frame. When necessary, the connecting beams 14 can also be used as a shelf platform for storing steel plates.

[0032] like Figures 7 to 9 , the cargo drawer 2 is used to store and retrieve steel plates and is set on the supporting beam of the vertical steel structure. Each cargo drawer 2 includes a load-bearing truss 21 and two carrying trolleys 22, wherein the load-bearing truss 21 is used to place and set the steel plates and connect the two carrying trolleys 22 into one, and its strength is sufficient to meet the load of 10 tons. The carrying trolleys 22 are set on both sides of the load-bearing truss 21, driven by a motor and the motors of the carrying trolleys 22 on both sides run synchronously. The motor 221 is a reduction motor with an integrated reducer. When the motor 221 drives the carrying trolleys 22 on both sides to move, the carrying trolleys 22 can cooperate with the track 13 to drive the cargo drawer 2 to move on the supporting beam 12 of the vertical steel structure 1. To facilitate the storage and retrieval of steel plates, the horizontal area of ​​the cargo drawer 2 only occupies half of the horizontal area of ​​the vertical steel structure 1. When the cargo drawer 2 moves to the outside of the vertical steel structure 1, there is no positional interference between the steel plates and the shelf as a whole, and the steel plates can be stored or retrieved normally by the crane.

[0033] The transport trolley 22 consists of a motor 221, a driving wheel set 222, a driven wheel set 223, and a trolley crossbeam 224. The driving wheel set 222, driven by the motor 221, is responsible for providing power and torque, and drives the driven wheel set 223 to move together. The motor 221, which is integrated with a reducer, is mounted on the trolley crossbeam and relies on open gears to provide transmission torque to the driving wheel set 222. The small gear is mounted on the reducer of the motor 221, and the large gear is integrated with the wheel of the driving wheel set 222. Considering that the shelves are usually set up in dusty warehouse environments, the motor 221 adopts a deep groove ball bearing structure with a dust cover and self-lubricating.

[0034] like Figure 10 The trolley crossbeam 224 is used to mount the driving wheel assembly 222 and the driven wheel assembly 223. To facilitate installation, the trolley crossbeam 224 features a U-shaped groove structure, allowing the driving and driven wheel assemblies to be installed directly from the bottom up. The trolley crossbeam 224 also uses a clamping plate to secure the mounting structure of the driving and driven wheel assemblies. The configuration of the trolley crossbeam 224 makes assembly and processing of the transport trolley 22 easier. To increase the load bearing capacity, the trolley crossbeam 224 is equipped with a reinforcement plate.

[0035] like Figure 3 、 Figure 4 In order to prevent the cargo drawer 2 from over-operating and causing instability in the steel plate setting, a stroke limit device 3 is installed on the column 11 of the vertical steel structure 1. The stroke limit device 3 is a limit switch. When the carrying trolley 22 moves to the end of the track 13, the stroke limit device 3 will disconnect the operating current of the carrying trolley 22, thereby stopping the carrying trolley 22. The stroke limit device 3 can adopt a variety of designs such as photoelectric, electromagnetic or mechanical. In the present utility model, considering the working environment of the shelf and the structure of the carrying trolley 22, the stroke limit device 3 is a mechanical limit switch provided with a roller rotating arm 31. The roller rotating arm 31 can achieve the optimal stroke limit requirements for the carrying trolley 22 and the cargo drawer 2 through its mechanical structure with adjustable length and angle. When the trolley 22 drives the cargo drawer 2 to the end of the track 13, the trolley 22 will trigger the roller rotating arm 31, causing the travel limit device 3 to cut off the current of the trolley 22. After the power is cut off, the trolley 22 will stop running together with the cargo drawer 2.

[0036] like Figure 4 As a preferred embodiment of the present invention, buffer blocks 225 are also installed at both ends of the transport trolley 22. The buffer blocks 225 can absorb the power when the transport trolley 22 stops, so that the transport trolley 22 can stop more smoothly.

[0037] The above description describes the structure, specific features, methods of use, and advantages of the present invention. It should be noted that the specific implementation of the present invention is not limited to the above-described methods. Any non-substantial improvements made using the technical solution of the present invention, or any direct application of the concept and technical solution of the present invention to other situations without modification, are all within the scope of protection of the present invention. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
