Description

Technical Field

[0001] This utility model relates to the field of coal sample bottle storage technology, and more specifically, to a sample bottle storage rack based on a U-shaped tray. Background Technology

[0002] The grade of coal directly determines its calorific value and, consequently, its selling price. To conduct quality testing and price determination on incoming coal, large coal users such as power plants and steel mills typically install coal sampling and quality testing equipment, conduct real-time random checks on incoming coal, and perform corresponding experimental tests. Furthermore, to ensure the test data can be subsequently verified, they usually maintain a corresponding sample storage facility to store backup samples for a certain period.

[0003] Coal samples are typically stored in sealed sample containers in a low-temperature storage facility to ensure the coal is kept in a dark environment with a slow oxidation rate. Therefore, the storage facility is an important and indispensable piece of equipment in the coal sample analysis and preservation process.

[0004] The sample storage area is equipped with storage stations for coal sample bottles. These stations typically include wall-mounted sheet metal racks, round storage cylinders, and tray-type storage racks. However, as... Figure 1 As shown, the sheet metal coal sample bottle holder structure is long, with only two side ribs on each module. When storing many sample bottles, there are no ribs in the middle, resulting in insufficient strength and easy deformation. Furthermore, its unit modules are scattered, making assembly errors difficult to control. After installation, the accuracy of the coal sample bottle storage position is not high, and the calibration and debugging time for the sample storage and retrieval system is long. In circular bottle storage cylinders, such as the Chinese utility model patent "An Intelligent Sample Storage and Retrieval Cabinet System" (publication number CN205526139U), sample bottles are stacked. When storing or retrieving inner sample bottles, outer sample bottles must first be moved out, making the system's bottle storage and retrieval process complex. For tree-shaped tray storage holders, such as... Figure 2 As shown, firstly, the vertical placement of tall sample bottles results in low space utilization and a small number of bottles stored vertically; secondly, the use of a single sheet metal tray to store multiple sample bottles makes the tray prone to deformation, leading to insufficient accuracy in the position of the sample bottles. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] Based on this, the present invention provides a sample bottle storage rack based on a U-shaped tray to solve the problems of low space utilization in the sample storage and retrieval warehouse, complex bottle storage and retrieval process, and easy deformation of the sample bottle storage position.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides a sample bottle storage rack based on a U-shaped tray, including a tray shaft, a tray fixing frame, and a sample bottle tray. The tray shaft has multiple horizontally arranged tray fixing frames along its axial direction, and the vertical distance between adjacent tray fixing frames is equal. Each layer of tray fixing frames has multiple bottle holding stations on its outer periphery, and each bottle holding station contains a sample bottle tray. Each sample bottle tray can support a horizontally placed sample bottle.

[0009] The sample bottle tray is made of a sheet metal plate by bending, and the cross-section of the sample bottle tray is U-shaped; the bottom plate of the sample bottle tray is provided with reinforcing ribs.

[0010] Preferably, the bracket shaft is provided with positioning holes that are equidistant from top to bottom, and the positioning holes are used to install the tray fixing frame.

[0011] Preferably, the tray fixing frame is provided with a plurality of U-shaped mounting holes evenly distributed along its outer periphery, the mounting holes being used to mount the sample bottle tray; the bottom plate of the sample bottle tray is lower than the upper surface of the tray fixing frame in the vertical direction.

[0012] Preferably, the mounting hole and the sample bottle tray are connected by a snap-fit ​​connection.

[0013] Preferably, the tray holder is a regular octagonal structure, and a sample bottle tray is provided on the outer side of each side of the regular octagonal structure.

[0014] Preferably, the sample bottle is a coal sample bottle.

[0015] Preferably, the tray fixing frame has 13 layers.

[0016] Preferably, the lower part of the bracket shaft is connected to a stepper motor, which can drive the entire sample bottle storage bracket to rotate.

[0017] (III) Beneficial Effects

[0018] The above-mentioned technical solution of this utility model has the following advantages:

[0019] 1. This utility model integrates and optimizes the fixing structure of the sample bottle with the tree-shaped multi-layered tray structure. By aligning the horizontally placed coal sample bottle with each side of the polygonal circumference, the space utilization rate of the sample storage area is improved. Compared with the existing vertical storage method of sample bottles, the horizontal placement of sample bottles compresses the vertical space. Under the same height, a certain number of sample bottles can be stored. For example, at the same height, when the same type of coal sample bottle is stored vertically in 8 layers, the horizontal placement scheme of this utility model can reach 13 layers. Moreover, for sample bottles of the same diameter, the higher the bottle height, the more advantageous this scheme becomes.

[0020] 2. The advantages of pallet support are that each pallet has reinforcing ribs, strong load-bearing capacity, small deformation, and high positional accuracy, which can reduce the risk of collision between the robot and the pallet, thereby improving the reliability of the sample storage system.

[0021] 3. Each sample bottle tray is made from a single sheet metal piece through bending, and the cross-section of the sample bottle tray is U-shaped. The two side plates of the sample bottle tray protect the sample bottles, and when the bottle tray station rotates, the two side plates can prevent the sample bottles from being thrown out due to centrifugal force. The bottom plate of the sample bottle tray is lower than the upper surface of the tray fixing frame in the vertical direction, so that the sample bottles will not move towards the axis of the tray when the sample bottle storage tray rotates. Moreover, the tray has a simple structure, is easy to process, and has low material cost. Attached Figure Description

[0031] Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0034] like Figure 4-6 As shown, by integrating and optimizing the sample bottle fixing structure and the tree-shaped multi-layer tray structure, this utility model improves the design of a sample bottle storage rack 1 for horizontally storing sample bottles. The sample bottle storage rack 1 includes a rack shaft 1-1, a tray fixing frame 1-2, and a sample bottle tray 1-3. The rack shaft 1-1 has multiple horizontally arranged tray fixing frames 1-2 along its axial direction, and the vertical distance between adjacent tray fixing frames 1-2 is equal. Each layer of tray fixing frame 1-2 has multiple bottle holding positions on its outer periphery. Each bottle holding position contains a sample bottle tray 1-3, and each sample bottle tray 1-3 can support a horizontally placed sample bottle.

[0035] Each sample bottle tray 1-3 is manufactured from a single sheet metal plate by bending. The cross-section of the sample bottle tray 1-3 is U-shaped. The two side plates of the sample bottle tray 1-3 protect the sample bottles, preventing them from being thrown out by centrifugal force when the bottle-holding station rotates. The bottom plate of the sample bottle tray 1-3 is equipped with reinforcing ribs, enhancing its load-bearing capacity and providing more even support. Therefore, the sample bottle tray 1-3 exhibits minimal deformation and positional variation, resulting in high positional accuracy of the bottle-holding station. Furthermore, the sample bottle tray 1-3 has a simple structure, is easy to manufacture, and has low material costs.

[0036] Therefore, the sample bottle storage rack of this utility model improves the space utilization of the sample storage warehouse. Multiple sets of this type of sample bottle storage rack 1 can be placed in one sample storage cabinet. The working principle of this rack in the sample storage warehouse is as follows: when sample bottles need to be stored, the sample storage cabinet system randomly selects a station in the rack. The rack rotates around the rack axis to rotate the station to the gripper position. The robot moves up and down to the station position for storage. The sample bottle retrieval process is similar.

[0037] In another implementation, such as Figure 3-4 As shown, the sample bottle of this utility model is specifically a coal sample bottle 2. The coal sample bottle 2 is placed horizontally on the sample bottle tray 1-3, and the coal sample bottle 2 is arranged in multiple layers in a circular pattern.

[0038] In another embodiment, the bracket shaft 1-1 is provided with equidistant positioning holes for mounting the tray fixing frame 1-2, ensuring consistent vertical spacing and thus guaranteeing the positional accuracy of the sample bottles. Furthermore, the tray fixing frame 1-2 has multiple U-shaped mounting holes evenly distributed upwards along its outer circumference for mounting the sample bottle tray 1-3. The bottom plate of the sample bottle tray 1-3 is lower than the upper surface of the tray fixing frame 1-2 in the vertical direction, preventing the sample bottles 2 from moving towards the bracket shaft 1-1 when the sample bottle storage bracket 1 rotates. The mounting holes and the sample bottle tray 1-3 can be connected by snap-fit ​​connections.

[0039] In another implementation, such as Figure 5-6 As shown, the tray holder 1-2 is a regular polygonal structure, and a sample bottle tray 1-3 is provided on the outer side of each side of the regular polygonal structure for storing sample bottles.

[0040] In another embodiment, the tray holder 1-2 is specifically an octagonal structure, and the total number of sample bottle trays 1-3 installed on its eight sides is 8.

[0041] In another embodiment, a drive motor is connected below the bracket shaft 1-1. The drive motor can rotate the entire sample bottle storage bracket 1 to rotate the corresponding workstation to the gripper position. The robot then moves up and down to this workstation position to perform the storage and retrieval operation of the coal sample bottle 2. The drive motor is preferably a stepper motor to facilitate control of the rotation angle of the tray fixing frame 1-2.

[0042] The characteristics of the sample bottle storage method of this utility model are: 1. The sample bottles are arranged in a multi-layered polygonal circle with the sample bottles lying horizontally; 2. The tray storage method is combined with the circumferential arrangement.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model, and not to limit it; although the implementation of this utility model has been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this utility model, and such modifications and variations all fall within the scope defined by the appended claims.
