Description

Technical Field

[0001] This utility model relates to the field of weighing and measuring equipment technology, specifically a direct-display electronic crane scale. Background Technology

[0002] Electronic crane scales are widely used in cargo weighing operations due to their ease of operation and wide measuring range. However, existing electronic crane scales have many shortcomings.

[0003] Traditional crane scales suffer from unreasonable structural design and poor stability of connecting components, making them prone to swaying and shifting during cargo lifting. This not only affects weighing accuracy but also poses a safety hazard of goods falling. Furthermore, their functionality is limited, lacking convenient operation and display design, making it difficult for operators to quickly read weighing data during lifting, especially in high-altitude operations or poor lighting conditions, leading to low work efficiency. Moreover, some crane scales have insufficient durability of their detection components, easily experiencing accuracy degradation after prolonged use, requiring frequent calibration and maintenance, increasing operating costs and maintenance workload. Therefore, a direct-display electronic crane scale is proposed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model discloses a direct display electronic crane scale, including a housing 1, a control panel 2 fixedly connected to one side of the outer wall of the housing 1, and a top rotating seat 3 fixedly connected to the top of the housing 1. A rotating frame 4 is rotatably connected to the inner wall of the top rotating seat 3, and a connecting terminal 5 is fixedly connected to the top of the rotating frame 4.

[0023] A connecting arm 6 is rotatably connected to one side of the outer wall of the connecting terminal 5. A top fixing seat 7 is fixedly connected to the end of the connecting arm 6 away from the connecting terminal 5. A card interface 8 is fixedly connected to the top of the top fixing seat 7.

[0024] Specifically, this direct-display electronic crane scale uses the housing 1 as its core carrier, integrating a control panel 2 to realize operation and display functions. A flexible and stable suspension connection structure is formed by the top rotating seat 3, rotating frame 4, connecting terminal 5, connecting arm 6, top fixed seat 7, and card interface 8. The detector 9, fixed rod 10, fixed frame 11, scale beam 12, telescopic spring 13, bottom fixed terminal 14, rotating port 15, hook frame 16, bottom fixed plate 17, and hook 18 work together to achieve accurate detection and transmission of cargo weight. The cooperation of these components gives the crane scale the characteristics of stable structure, convenient operation, and accurate measurement. The control panel 2, fixedly connected to one side of the outer wall of the housing 1, allows operators to quickly set functions and read data in various environments. The top rotating seat 3 at the top of the housing 1 is internally equipped with a high-precision deep groove ball bearing, allowing the rotating frame 4 to rotate flexibly, facilitating adjustment of the crane scale's direction during lifting. The connecting terminal 5 at the top of the rotating frame 4 is connected to the connecting arm 6 through a rotating joint. The connecting arm 6 can swing in the vertical plane, which enhances the adaptability of the crane scale when lifting irregular goods. The card interface 8 on the top fixed seat 7 adopts a wedge-shaped card slot design and is equipped with an anti-slip rubber pad inside, which can fit tightly with the hook 18 to ensure the stability of the connection during the lifting process.

[0025] In this embodiment, a detector 9 is fixedly connected to the bottom end of the top fixing seat 7, a plurality of fixing rods 10 are fixedly connected to the outer wall of the detector 9, and a fixing frame 11 is fixedly connected to the bottom end of the plurality of fixing rods 10.

[0026] Specifically, the detector 9 at the bottom of the top mounting base 7 adopts a high-precision strain gauge load cell, which can accurately convert the pressure generated by the weight of the goods into an electrical signal. Multiple fixing rods 10 fixed to the outer wall of the detector 9 are arranged in a ring and welded to the fixing frame 11 to provide stable support for the detector 9 and reduce the impact of external vibration on the detection accuracy.

[0027] In this embodiment, a weighing rod 12 is fixedly connected to the bottom end of the detector 9, and a telescopic spring 13 is fixedly connected to the outer wall of the weighing rod 12.

[0028] Specifically, the weighing rod 12 at the bottom of the detector 9 is made of high-strength alloy steel and its strength and toughness are enhanced by heat treatment. The telescopic spring 13 on the outer wall of the weighing rod 12 is a helical compression spring, which can play a buffering role when hoisting goods, reducing the impact of instantaneous impact on the detector 9. At the same time, it allows the weighing rod 12 to produce elastic deformation after being subjected to force, accurately transmitting the force to the detector 9. The bottom fixed terminal 14, rotating port 15, hook frame 16, bottom fixed plate 17 and hook 18 are connected in sequence to form a stable cargo suspension structure.

[0029] In this embodiment, the top end of the telescopic spring 13 is fixedly connected to the bottom end of the fixing frame 11, and the bottom end of the telescopic spring 13 is fixedly connected to the bottom end fixing terminal 14.

[0030] Specifically, the telescopic spring 13 on the outer wall of the weighing beam 12 is a helical compression spring, which can play a buffering role when hoisting goods and reduce the impact of instantaneous impact force on the detector 9.

[0031] In this embodiment, the bottom fixing terminal 14 is located directly below the detector 9, and the bottom end of the bottom fixing terminal 14 is fixedly connected to the rotating port 15.

[0032] Specifically, the rotating port 15 is fixed by setting the bottom fixing terminal 14.

[0033] In this embodiment, a hook frame 16 is fitted on the outer wall of the rotating port 15, and a bottom fixing plate 17 is fixedly connected to the bottom end of the hook frame 16.

[0034] Specifically, by setting up the hook bracket 16, the bottom fixing plate 17 can be fixed more securely.

[0035] In this embodiment, a hook 18 is fixedly connected to the bottom end of the bottom fixing plate 17, and the hook 18 corresponds to the card interface 8.

[0036] Specifically, by setting hook 18, the external weighing object can be fixed.

[0037] The working principle and usage process of this utility model are as follows: When using the direct-display electronic crane scale for weighing, first turn on the crane scale through the control panel 2. The LCD screen displays initialization information. After the equipment completes its self-test, it enters the weighing standby state. Hang the hook 18 at a suitable position on the goods to be weighed. The weight of the goods is transmitted to the bottom fixing plate 17 through the hook 18, and then acts on the telescopic spring 13 and the weighing beam 12 through the hook frame 16, the rotating port 15, and the bottom fixing terminal 14. Under the action of the weight of the goods, the weighing beam 12 undergoes elastic deformation, which drives the telescopic spring 13 to compress, accurately transmitting the force to the detector 9. The strain gauge load cell inside the detector 9, after being subjected to pressure, converts the weight of the goods into a weak electrical signal, which is then transmitted to the control panel 2 as a digital signal. The control panel 2 processes and calculates the received digital signal and displays the weight of the goods in an intuitive digital form on the LCD screen. The operator can read the weighing data in real time. During the hoisting process, the top rotating seat 3, rotating frame 4, connecting terminal 5 and connecting arm 6 work together to enable the crane scale to flexibly adjust its angle and direction to adapt to different hoisting needs. At the same time, the tight cooperation between the locking interface 8 and the hook 18 ensures the stability and safety of the goods during the hoisting process.
