Description

Technical Field

[0001] The utility model belongs to the technical field of electronic truck scales, and particularly relates to an electronic truck scale with a reinforced structure to prevent subsidence. Background Technique

[0002] The working principle of an electronic truck scale is based on the strain electrical measurement principle. When a truck is placed on the carrier table, under the action of gravity, the gravity is transmitted to the load cell through the carrier. The elastic body of the load cell deforms, and the strain gauge bridge circuit attached to the elastic body loses balance, outputting an electrical signal proportional to the weight value. This electrical signal is amplified by a linear amplifier and then converted into a digital signal through A / D conversion. After being processed by the microprocessor (CPU) of the weighing display instrument, the weight data is directly displayed.

[0003] After patent retrieval, there is a Chinese utility model of an electronic truck scale with a reinforced structure to prevent lower limit, with the publication number of CN 219368894 U, including an electronic truck scale body. One side of the electronic truck scale body is provided with an impeller, and a reciprocating lead screw is fixedly connected inside the impeller. The reciprocating lead screw is rotatably connected inside the electronic truck scale body. For this electronic truck scale with a reinforced structure to prevent lower limit, as the water pressure approaches, the sediment can be washed cleaner. The water flows along the edge of the electronic truck scale body into the filter box, and after being filtered by the filter screen, it then flows into the water collection tank through the first pipeline, thereby recycling the water, saving energy, and avoiding waste. Using this method can not only keep the top of the electronic truck scale body beautiful and clean without manual cleaning, but also ensure the weighing accuracy of the electronic truck scale body.

[0004] In the above patent, a chute is provided on the electronic truck scale, and a reciprocating lead screw is arranged in the chute. When a vehicle drives onto the electronic truck scale, it will carry sludge into the chute. Also, when cleaning the upper surface of the electronic truck scale, sewage and sludge will also enter the chute. However, the sludge entering the chute is inconvenient to clean and will also affect the rotation of the reciprocating lead screw, thereby affecting the normal use of the equipment. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an electronic truck scale with a reinforced structure to prevent subsidence, which cancels some structures on the upper surface of the electronic truck scale, avoids the sludge affecting the normal operation of the equipment when the vehicle is driving or the electronic truck scale is being cleaned, cleans the sludge on the main body of the electronic truck scale, has a good cleaning effect, keeps the top of the electronic truck scale body beautiful and clean without manual cleaning, and can ensure the weighing accuracy of the electronic truck scale body at the same time.

[0021] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.

[0022] As Figures 1-3As shown in the figure, an electronic truck scale with a reinforced structure to prevent subsidence includes an electronic truck scale main body 1. A lead screw moving mechanism is arranged on one side of the electronic truck scale main body 1. The output end of the lead screw moving mechanism is rotatably installed with a mounting shaft 7. A gear 9 is arranged outside the mounting shaft 7. A torsion spring 10 is arranged on the outer wall of the mounting shaft 7 and below the gear 9. A toothed plate 11 meshing with the gear 9 is arranged on one side of the electronic truck scale main body 1. A fixing plate 8 is fixed at the top of the mounting shaft 7. A cleaning brush 12 is bolted to the bottom of the fixing plate 8. By the movement of the cleaning brush 12, the sludge on the electronic truck scale main body 1 can be cleaned. A limiting plate 13 is fixed on the output end of the lead screw moving mechanism and on one side of the mounting shaft 7, which can limit the rotation of the fixing plate 8, so that the cleaning brush 12 can be horizontally perpendicular to the electronic truck scale main body 1, thus comprehensively cleaning the electronic truck scale main body. A guide ring 14 is fixed on the outer wall of the fixing plate 8. A guide hole slidably connected with the guide ring 14 is formed through the outer wall of the limiting plate 13. The cooperation of the guide hole and the guide ring 14 makes the fixing plate 8 rotate stably and also improves the installation stability of the fixing plate 8. After each use, sludge left by the front vehicle wheels will be generated on the top of the electronic truck scale body 1. Therefore, it is necessary to clean the sludge on the top of the electronic truck scale main body 1. The lead screw moving mechanism drives the mounting shaft 7 to move. The gear 9 on the mounting shaft 7 contacts and meshes with the toothed plate 11, driving the mounting shaft 7 to rotate. The mounting shaft 7 drives the fixing plate 8 and the cleaning brush 12 to rotate, so that the cleaning brush 12 contacts the top of the electronic truck scale main body 1. When the gear 9 is separated from the toothed plate 11, with the cooperation of the torsion spring 10, the cleaning brush 1 can be stably horizontally perpendicular to the electronic truck scale main body 1, and then the sludge on the electronic truck scale main body 1 is cleaned by the movement of the cleaning brush 12; the number of teeth of the toothed plate 11 is one-fourth of the number of teeth of the gear 9, so that during the meshing process of the gear 9 and the toothed plate 11, the gear 9 and the mounting shaft 7 can only rotate ninety degrees, thus facilitating the rotation and folding of the fixing plate 8;

[0023] As Figures 1-3 shown, the lead screw moving mechanism includes a mounting plate 2 fixed on one side of the electronic truck scale main body 1. A moving groove 3 is formed on one side of the mounting plate 2. A reciprocating lead screw 4 is rotatably installed inside the moving groove 3. A moving block 6 is screwed on the outer wall of the reciprocating lead screw 4. A motor 5 is fixed on one side of the electronic truck scale main body 1. The output shaft of the motor 5 is connected to one end of the reciprocating lead screw 4. The moving block 6 is the output end of the lead screw moving mechanism. The motor 5 drives the reciprocating lead screw 4 to rotate. The reciprocating lead screw 4 drives the moving block 6 to move. The moving block 6 drives the fixing plate 8 on the mounting shaft 7 to move. The fixing plate 8 drives the cleaning brush 12 to move, so as to clean the upper surface of the electronic truck scale main body 1 through the cleaning brush 12 on the fixing plate 8;

[0024] As Figure 1 、 2As shown in FIGS. 3 and 4, a water distribution box 15 is provided on one side of the fixed plate 8. A connecting hose 17 is provided through one side of the water distribution box 15. A plurality of flushing heads 16 are provided on the outer wall of the water distribution box 15 and on one side of the connecting hose 17. The nozzle of the flushing head 16 is flat-shaped, increasing the area of water spraying. It is connected to an external water pump and water tank through the connecting hose 17. Driven by the external water pump, water enters the water distribution box 15 and finally sprays out from the flushing heads 16 and sprays onto the upper surface of the electronic truck scale main body 1;

[0025] As Figure 4 shown, collection grooves 18 are formed on both slope surfaces of the electronic truck scale main body 1, facilitating the collection of water used for cleaning. Filter plates 19 are provided on both slope surfaces of the electronic truck scale main body 1 corresponding to the collection grooves 18, which can filter the sewage, enabling the cleaning water to meet the discharge requirements and can also be reused, being relatively resource-saving and environmentally friendly. A sewage pipe communicating with the collection groove 18 is provided on one side of the electronic truck scale main body 1;

[0026] As Figure 2 shown, reinforcing ribs 20 are provided at the bottom of the electronic truck scale main body 1. The reinforcing ribs 20 are formed by reinforcing rods arranged horizontally and vertically at the bottom of the electronic truck scale main body 1, which can disperse the force received by the electronic truck scale main body 1 as much as possible, thereby preventing the electronic truck scale main body 1 from sinking during the process of being run over by a vehicle.

[0027] The working principle of the present utility model is as follows: When in use, it is connected to an external water pump and water tank through a connecting hose 17. The motor 5 is started, and the motor 5 drives the reciprocating lead screw 4 to move. The reciprocating lead screw 4 drives the moving block 6 to move. The moving block 6 drives the mounting shaft 7 to move. The mounting shaft 7 drives the gear 9 to move. The gear 9 meshes with the toothed plate 11. During the contact between the gear 9 and the toothed plate 11, the mounting shaft 7 rotates by 90 degrees, thereby causing the fixing plate 8 to rotate by 90 degrees, and making the cleaning brush 12 on the fixing plate 8 perpendicular to the electronic weighbridge main body 1 horizontally, so that the cleaning brush 12 contacts the top of the electronic weighbridge main body 1. When the gear 9 is completely disengaged from the toothed plate 11, through the setting of the torsion spring 10 and in cooperation with the limit plate 13, one end of the fixing plate 8 contacts the limit plate 13 for limiting. The torsion spring 10 has a torsional force on the fixing plate 8 towards the limiting direction, improving the stability of fixing the fixing plate 8 and the cleaning brush 12. Then, the sludge above the electronic weighbridge main body 1 is cleaned by the movement of the fixing plate 8 and the cleaning brush 12. At the same time, through an external water pump, the water in the water tank enters the water distribution box 15, and finally is sprayed onto the electronic weighbridge main body 1 through the flushing head 16 for flushing, improving the cleaning effect of the sludge on the electronic weighbridge main body 1. It is relatively practical. After use, through the motor 5, the reciprocating lead screw 4 and the moving block 6, the gear 9 is meshed with the toothed plate 11 again, so that the gear 9 rotates. The gear 9 drives the fixing plate 8 on the mounting shaft 7 to reverse by 90 degrees, and further makes the fixing plate 8 parallel to the electronic weighbridge main body 1 horizontally. When not in use, the fixing plate 8 can be rotated and folded to avoid affecting the normal use of the equipment.

[0028] The above is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in this field.
