Description

Technical Field

[0001] This utility model belongs to the field of weighing instrument technology, specifically relating to a lightweight weighing instrument calibration and hoisting mechanism. Background Technology

[0002] A weighing instrument is a device that uses Hooke's Law or the lever principle of force balance to determine the mass of an object. A weighing instrument mainly consists of three parts: a weight-bearing system (such as the weighing pan), a force transmission system (such as a lever transmission system), and a display system (such as a graduated dial). Based on their structural principles, weighing instruments can be divided into three main categories: mechanical scales, electronic scales, and electromechanical scales. Weighing instruments are widely used in industry, agriculture, commerce, scientific research, and medical and health sectors. Mechanical scales are further divided into lever scales and spring scales. Weighing scales are categorized into non-automatic and automatic scales based on their weighing method. The main types include balances, lever scales, platform scales, bench scales, ground scales, ground scales, rail scales, belt scales, postal scales, crane scales, batching scales, and bagging scales. To ensure the accuracy and reliability of weighing instruments, a lifting mechanism is needed for calibration. However, current calibration methods typically involve manually placing weights on the scale, which can lead to weights slipping and reducing calibration accuracy. Therefore, a lightweight weighing instrument calibration lifting mechanism is needed. Utility Model Content

[0003] To address the problems mentioned in the background art, this utility model provides a lightweight weighing instrument calibration hoisting mechanism, which solves the problem that current weighing instrument calibration methods generally involve manually placing weights on the instrument, which results in the weights not being placed stably on the designated load-bearing points, easily causing the weights to slip and reducing the accuracy of the weighing instrument calibration.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a lightweight weighing instrument calibration and hoisting mechanism, comprising an electric slide rail, a first slider slidably connected to the surface of the electric slide rail, a support block provided at the top of the first slider, a crossbeam fixedly installed at the top of the support block, an electric slide table fixedly installed at the bottom of the crossbeam, a second slider slidably connected to the surface of the electric slide table, an electric hydraulic push rod fixedly installed at the bottom of the second slider, a U-shaped housing fixedly connected to one end of the electric hydraulic push rod, connecting blocks fixedly installed on both sides of the U-shaped housing, a first electric push rod fixedly installed on the inner wall of the connecting block, a clamping plate fixedly connected to one end of the first electric push rod, a fixing block fixedly installed on the surface of the support block, a connecting plate fixedly installed on one side of the fixing block, a second electric push rod fixedly installed on the inner wall of the connecting plate, a support plate fixedly connected to one end of the second electric push rod, and weights provided on the surface of the support plate.

[0005] Preferably, the surface of the support block is provided with locking bolts, and the support block is connected to the first slider through the locking bolts.

[0006] Preferably, the surface of the clamping plate is provided with a rubber sleeve, and the number of clamping plates is two.

[0007] Preferably, the electric slide is connected to the electro-hydraulic push rod via a second slider, and the electric slide is located above the support plate.

[0008] Preferably, the surface of the tray is provided with a slot.

[0009] Preferably, a lighting fixture is fixedly installed on the surface of the support block.

[0010] Preferably, a reflective warning sticker is fixedly installed on one side of the support block, and the number of reflective warning stickers is two.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The first electric push rod starts and moves the clamping plate to clamp and fix the weight, thus hoisting the weight. After the electric slide is started, the second slider can move the clamped and hoisted weight laterally, and after the electric slide rail is started, the first slider can move the weight vertically. The electric hydraulic push rod can move the weight onto the weighing instrument. Because the weight can move flexibly and freely, it is placed stably on the designated bearing point of the weighing instrument, ensuring the accuracy of the weighing instrument calibration and preventing the weight from slipping.

[0019] Please see Figure 1-3 This utility model provides the following technical solution: a lightweight weighing instrument calibration and hoisting mechanism, including an electric slide rail 1, a first slider 2 slidably connected to the surface of the electric slide rail 1, a support block 3 provided on the top of the first slider 2, a crossbeam 4 fixedly installed on the top of the support block 3, an electric slide table 5 fixedly installed on the bottom of the crossbeam 4, a second slider 6 slidably connected to the surface of the electric slide table 5, an electric hydraulic push rod 7 fixedly installed on the bottom of the second slider 6, a U-shaped housing 8 fixedly connected to one end of the electric hydraulic push rod 7, connecting blocks 9 fixedly installed on both sides of the U-shaped housing 8, a first electric push rod 10 fixedly installed on the inner wall of the connecting block 9, a clamping plate 11 fixedly connected to one end of the first electric push rod 10, a fixing block 12 fixedly installed on the surface of the support block 3, a connecting plate 13 fixedly installed on one side of the fixing block 12, a second electric push rod 14 fixedly installed on the inner wall of the connecting plate 13, a support plate 15 fixedly connected to one end of the second electric push rod 14, and weights 16 provided on the surface of the support plate 15.

[0020] The weight is placed on the surface of the tray 15. The second electric push rod 14 is activated, causing the tray 15 to move and move the weight on the surface of the tray 15 below the clamping plate 12. The electric hydraulic push rod 7 is activated, causing the clamping plate 11 to press down, so that the weight 16 is located between the two clamping plates 11. The first electric push rod 10 is activated, causing the clamping plate 11 to move and clamp the weight 16, thus hoisting the weight 16. At the same time, after the electric slide table 5 is activated, it can move the weight 16 hoisted by the clamping plate 11 laterally through the second slider 6. And after the electric slide rail 1 is activated, it can move the weight 16 vertically through the first slider 2. After the weight 16 is moved above the weighing instrument, the electric hydraulic push rod 7 can drive the weight 16 to be placed on the weighing instrument. Since the weight 16 can move flexibly and freely, it can be placed stably on the designated bearing point of the weighing instrument, ensuring the accuracy of the weighing instrument calibration and preventing the weight from slipping. The reflective warning sticker 18 is used to warn and remind the user of the hoisting position. The lighting fixture 17 is used to illuminate the position of the weighing instrument in use, improve the brightness of the weighing instrument during the calibration process, and facilitate the observation of the weighing instrument during the calibration process. All electrical equipment in this device is powered by an external power supply. The electric slide rail, electric slide table, and electric push rod light of this utility model are all controlled by a PLC automatic control system.

[0021] In one aspect of this embodiment, the rubber sleeve on the surface of the clamping plate 11 is used to protect the weight 16 being clamped and hoisted, preventing the weight 16 from falling off during the clamping process.

[0022] In one aspect of this embodiment, after the locking bolts on the support block 3 are loosened, the support block 3 can be removed from the first slider 2, thereby facilitating the installation and removal of the support block 3.

[0023] In one aspect of this embodiment, a slot on the surface of the tray 15 is used to place the weight 16.

[0024] In one aspect of this embodiment, after the electric slide table 5 is started, the electric slide table 5 can drive the electric hydraulic push rod 7 to move through the second slider 6, thereby driving the weight 16 to be clamped and lifted to move, so as to facilitate the lifting and handling of the weight 16 placed on the pallet 15.

[0025] In one aspect of this embodiment, the reflective warning sticker 18 is used to serve as a warning reminder of the hoisting position.

[0026] In one aspect of this embodiment, the lighting fixture 17 is used to illuminate the position of the weighing instrument, thereby increasing the brightness during the weighing instrument calibration process and facilitating observation of the weighing instrument during the calibration process.
