Description

Technical Field

[0001] The utility model relates to the technical field of truck scales, in particular to a stable truck scale weighing device. Background Art

[0002] Electronic truck scales are the primary instrument for measuring large cargo. Truck scales, also known as mechanical scales, have been replaced by the high-performance and easy-to-use electronic truck scales with the advancement of high-precision load cell technology. Electronic truck scales are industrial scales used for weighing. The most common use of electronic truck scales is to determine the weight of bulk cargo. In this case, the information they provide becomes a vital component of the transaction.

[0003] As a new type of electronic weighing instrument, electronic truck scales feature fast weighing, high precision, intuitive functions, and comprehensive functionality. However, since electronic truck scales can only make contact with the sensor, their range of motion becomes larger. Although limited positions can control their shaking, the vehicles weighed by electronic truck scales are often heavier, which results in high speeds when driving on the electronic truck scale. The increased inertia during braking increases the impact force on the electronic truck scale, causing the weighing platform to shake left and right, which in turn leads to sensor wear. Over time, this will further wear and tear on the electronic truck scale and the sensor underneath, leading to sensor damage. Therefore, the above problems need to be solved urgently.

[0027] Each telescopic mechanism of the present invention includes a hydraulic cylinder 9, a fixing rod 10, a buffer assembly 8, a bracket 12 and a push roller 11; Figures 1-3 As shown, in the groove 4 of each cement slope 3, several horizontally arranged hydraulic cylinders 9 are arranged in sequence along the longitudinal direction, and the tail of each hydraulic cylinder 9 is fixedly installed in the groove 4 of the corresponding cement slope 3 through a fixing rod 10; the piston rod of each hydraulic cylinder 9 extends horizontally and laterally out of the corresponding groove 4 toward the weighing platform 5, and is screwed and fixed to the fixed end of the corresponding buffer assembly 8; the buffer end of each buffer assembly 8 is arranged horizontally and laterally toward the weighing platform 5, and is respectively fixedly connected to the end of the corresponding bracket 12 away from the weighing platform 5, and a pushing roller 11 is also vertically and laterally provided at the end of each bracket 12 close to the weighing platform 5, and the front and rear ends of each pushing roller 11 are respectively connected to the corresponding bracket 12 for rotation around its own axis, and its rotation direction is consistent with the vertical direction of the weighing platform 5, and then under the drive of the hydraulic cylinder 9, each pushing roller 11 is tightly contacted with the corresponding side surface of the weighing platform 5, thereby tightly limiting the weighing platform 5.

[0029] The working principle of this utility model:

[0030] When the car is ready to be weighed, it first slows down by passing the speed bump 1 on the left side. At this time, the left infrared sensor 2 detects the car and, driven by the hydraulic cylinder 9, pushes the push roller 11 to contact the corresponding side of the weighing platform 5, thereby pressing the weighing platform 5 against the limit. The car then slows down further by passing the cement slope 3 on the left side and drives onto the weighing platform 5. When the car is completely on the weighing platform 5, the push roller 11 is separated from the weighing platform 5 by the drive of the hydraulic cylinder 9. At this time, the car is weighed by the cooperation of the weighing platform 5 and the load cell 6.

[0031] After weighing is completed, the signal indicator light 7 turns green. At this time, the push roller 11 is pressed against the corresponding side of the weighing platform 5 under the drive of the hydraulic cylinder 9, and the weighing platform 5 is pressed and limited. Then the car drives away through the cement slope 3 and the speed bump 1 on the right side in turn. When the infrared sensor 2 on the right side detects the car, the push roller 11 is separated from the weighing platform 5 under the drive of the hydraulic cylinder 9, and returns to its original state to wait for the next car to be weighed.

[0032] Beneficial effects of the utility model:

[0033] (1) The utility model can reduce the back-and-forth shaking of the weighing platform 5 caused by the inertia generated when the car is weighed and braked by using the cement slope 3 and the telescopic mechanism, thereby ensuring that the wear of the weighing sensor 6 and the displacement of the weighing platform 5 are minimized;

[0034] (2) The present invention uses the buffer assembly 8 and the push roller 11 to position the weighing platform 5 while buffering the displacement of the weighing platform 5, thereby minimizing the wear of the weighing sensor 6.
