[0020] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings.
[0021] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in one or more embodiments of the present application should be understood as the general meaning understood by those skilled in the art to which the present application belongs.

[0022] To facilitate the understanding of the calibration device provided by the embodiments of the present application, first, the application scenario thereof is described. The calibration device provided by the embodiments of the present application is applied to the calibration of a weighing device. The calibration device in the prior art is affected by the working condition environment or the interference between devices, which affects the calibration accuracy and is poor in safety and stability. Therefore, the embodiments of the present application provide a calibration device, which is used to cooperate with a calibration seat to calibrate a weighing device, improve the safety and stability, and ensure the calibration accuracy.
[0023] When the weighing device is calibrated, the automatic calibration device is more efficient and labor-saving. The standard weight is lifted by a lifting device, and the lifting device is a pneumatic cylinder or a hydraulic telescopic rod. The standard weight is placed on a weighing bottom plate or is lifted by a weighing tray. In the specific setting, the standard weight is lifted by the lifting device or the weight is placed on the weighing bottom plate by the lifting device for calibration. However, the interference is formed between the weight and the weighing bottom plate or the weighing tray. Due to the working condition environment factors, the weight is affected by the working condition environment and is displaced, which affects the weighing and is poor in safety and stability.
[0024] Therefore, the calibration device provided by the embodiments of the present application reduces the interference between devices, improves the stability and accuracy of calibration. The calibration device is described in detail below in combination with specific examples.
[0025] Reference Figure 1 is shown in FIG. 1, Figure 1 FIG. 1 shows a structure schematic diagram of the calibration device provided by the embodiments of the present application; Figure 2 FIG. 2 shows a structure schematic diagram of a weight base provided by the embodiments of the present application. The calibration device includes a weight base 4. The weight base 4 is used to cooperate with a calibration seat 5 to calibrate a weighing device 8. The calibration seats 5 are relatively distributed or equidistantly distributed on the weighing device 8. Each calibration seat 5 is calibrated by a corresponding weight base 4. In the present application, the weight base 4 is better in dealing with the vibration influence generated in the working condition environment and the interference between devices. The weight base 4 is adopted to have a non-contact structure between the bottom of the weight base 4 and the calibration seat 5, so as to prevent the weight block 6 from being displaced due to the vibration influence. In addition, the positioning and guiding contact performance between the weight base 4 and the calibration seat 5 in the present application is better, which ensures higher stability and safety, thereby improving the calibration accuracy.
[0026] Specifically, the calibration device further comprises a lifting assembly for driving the weight base 4 to vertically locate at a first set height and a second set height; it needs to be specifically pointed out that the lifting assembly drives the weight base 4 to locate at the first set height during the descending process; and when the weight base 4 is located at the first set height, the weight base 4 and the lifting assembly are free from interference, and the calibration seat 5 bears the weight of the weight base 4. During the ascending process of the lifting assembly, the weight base 4 is driven to locate at the second set height, and when the weight base 4 is located at the second set height, the weight base 4 and the calibration seat 5 are free from interference, and the lifting assembly bears the weight of the weight base 4.
[0027] In order to more accurately realize the guiding performance of the weight base 4 during the descending process from the second set height to the first set height, a guide groove is formed on the calibration seat 5 in the present application, which is a groove body with a chamfer structure. The chamfer structure can provide sufficient guiding space for the weight base 4 during the descending process. A guide block 42 is arranged on the weight base 4 and matches the guide groove, and the guide block 42 is a tapered block body matching the guide groove. As can be seen, during the movement of the tapered end of the guide block 42 downward to the guide groove, the groove body with the chamfer structure provides guiding performance, so that the guide block 42 is completely fitted into the guide groove, thereby loading the weight of the weight base 4 onto the calibration seat 5 during the continuous descending process of the lifting assembly, and realizing the calibration of the weighing equipment 8.
[0028] Meanwhile, the bottom of the weight base 4 is in a non-contact structure with the calibration seat 5 in the present application, which can effectively reduce the interference problem between the weight block 6 and the calibration seat 5, and cope with the displacement of the weight block 6 due to vibration in the working condition workshop. Specifically, the weight base 4 in the present application is assembled with a plurality of weight blocks 6 located directly below the calibration seat 5; the weight blocks 6 are matched with different weights to realize the calibration work of the weighing equipment 8.
[0029] The lifting assembly as the power output device in the present application comprises a connecting plate 2, a telescopic device 1 assembled on the connecting plate 2, and a lifting hook 3 connected to the telescopic device 1; wherein the lifting hook 3 is connected to the weight base 4. The telescopic device 1 adopts a pneumatic cylinder or a hydraulic telescopic rod, and the telescopic device 1 is assembled in an inverted manner on the connecting plate 2, and the rod head of the telescopic device 1 is connected with the lifting hook 3, which is connected to the weight base 4, so as to achieve that when the lifting assembly drives the weight base 4 to locate at the first set height, the guide block 42 is fitted inside the guide groove, and the weight of the weight block 6 on the weight base 4 is loaded onto the weighing equipment 8; and when the lifting assembly drives the weight base 4 to locate at the second set height, the guide block 42 is separated from the guide groove.
[0030] In combination Figure 2As shown in the figure, the weight base 4 in the application comprises a boom 43, a lifting ring 41 connected to the top end of the boom 43 and matched with the hook 3, and a guide block 42 fixedly assembled on the upper part of the boom 43. The bottom of the boom 43 is connected with a base 45, and the base 45 is provided with a boss 44 for limiting the displacement of a plurality of weight blocks 6. In the application, the length of the boom 43 can be adjusted by matching weight blocks 6 of different weights, and there is a certain moving gap between the lifting ring 41 and the hook 3, so that the hook 3 and the lifting ring 41 form a non-interference relationship during the continuous extension of the telescopic device 1. At the same time, the bottom of the calibration seat 5 is connected with a protective cover 7 for covering a plurality of weight blocks 6. As can be seen from the above structure, when the equipment needs to be calibrated, the telescopic device 1 is remotely controlled to descend by the electromagnetic valve, the telescopic rod is extended, the hook 3 is lowered, and the hook 3 drives the weight base 4 to fall. During the falling process of the weight base 4, the calibration seat 5 limits the movement of the weight base 4, so that the limiting block is located in the limiting groove of the calibration seat 5. At this time, due to the gap between the hook 3 and the lifting ring 41, the hook 3 continues to fall until the hook 3 and the lifting ring 41 are completely separated. The weight of the weight block 6 is loaded on the weighing equipment, and the weight loading process is completed. After waiting for the calibration to end, the telescopic device 1 starts the lifting action to restore the initial state, drives the weight base 4 to separate from the weighing equipment, and realizes unloading.
[0031] In the application, the guide block 42 and the guide groove are matched with each other to realize accurate positioning, accurately load the weight of the weight block 6 on the weighing device 8 for calibration, prevent the displacement of the weight block 6 caused by environmental vibration, affect the weighing and calibration, prevent the interference between the devices, and greatly improve the safety and stability.

Therefore, any omission, modification, equivalent replacement, improvement, etc. made in the spirit and principle of one or more embodiments of the present disclosure should be included in the protection scope of the present disclosure.

Any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be included in the protection scope of the present application.
