Technical Field

[0001] The present invention relates to the technical field of weighbridges, and in particular to an adjustment component, an installation structure and an adjustment method for a dynamic vehicle scale. Background Art

[0002] Large trucks often have serious overloading problems in order to load more goods, resulting in a large pressure on the dynamic vehicle scale used for highway over-limit detection during detection. The connection between the sensor bracket under the dynamic vehicle scale and the ground is prone to collapse after frequently bearing large loads, which increases its measurement error, affects its metrological performance, leads to inaccurate weighing, and affects the fair law enforcement of highway law enforcement departments. Due to unclear responsibilities, difficult rectification, and high replacement costs, these dynamic vehicle scales that are unqualified due to large errors cannot be used normally and need to be improved urgently. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art, and provide an adjustment component, an installation structure and an adjustment method for a dynamic vehicle scale, the initial pressure value of which is adjustable, reducing the maintenance cost.

[0004] To achieve the above purpose, the technical solution of the present invention is:

[0005] An adjustment component for a dynamic vehicle scale includes a first adjustment block, and a second adjustment block is arranged above the first adjustment block. The first adjustment block and the second adjustment block are coaxially arranged. The second adjustment block includes a table column at the lower end, and the table column is provided with a second groove. A connection block is slidably installed in the second adjustment block, and at least part of the connection block is located in the second groove. The first adjustment block includes a second boss at the upper end, and the second boss is provided with a first groove. When the connection block moves downward and extends into the first groove, the second adjustment block can drive the first adjustment block to rotate.

[0006] The first adjustment block includes a first boss at the bottom, and the bottom surface of the first boss is an inclined surface.

[0007] The second adjustment block further includes a top cap at the upper end of the table column. A groove one is provided at the upper end of the top cap, and a magnet component is detachably installed in the groove one. The magnet component can attract the connection block to separate the connection block from the top of the first adjustment block.

[0008] The first groove and the second groove are coaxially arranged and have matching sizes.

[0009] An installation structure for an adjustment component of a dynamic vehicle scale includes an adjustment component for a dynamic vehicle scale, and further includes a support plate. A plurality of adjustment components for a dynamic vehicle scale are installed on the support plate. A plurality of weighbridge sensor components are arranged below the support plate. The adjustment components for a dynamic vehicle scale correspond to the weighbridge sensor components one by one, and the upper end of the weighbridge sensor component abuts against the bottom surface of the first boss.

[0010] The second adjusting block is threadedly connected and inserted into the upper end of the support plate, and the first adjusting block is slidably connected and inserted into the lower end of the support plate. The first adjusting block includes a chassis, and a counterbore is provided at the bottom of the support plate, and the chassis is located in the counterbore.

[0011] The counterbore includes a counterbore seat surface at the upper end, and the upper end surface of the chassis fits against the counterbore seat surface.

[0012] The bottom of the weighbridge sensor assembly is installed on the ground.

[0013] An adjusting method for an adjusting assembly of a dynamic vehicle scale includes an installation structure of a dynamic vehicle scale adjusting assembly and a weighbridge, and further includes the following steps:

[0014] ① Take out the magnet component, separate the connecting block from the magnet component, and the lower end of the connecting block abuts against the upper end of the second boss;

[0015] ② Rotate the second adjusting block so that the lower end of the connecting block falls into the first groove;

[0016] ③ Continue to rotate the second adjusting block so that the first adjusting block rotates, thereby causing the first boss to rotate;

[0017] ④ Insert the magnet component, the upper end of the connecting block fits against the bottom of the magnet component, the bottom position of the connecting block is higher than the top of the second boss, and tighten the second adjusting block.

[0018] At the initial position, the upper end of the weighbridge sensor assembly abuts against the highest point of the bottom surface of the first boss.

[0019] The beneficial effects of the present invention are:

[0020] By rotating the first boss, the upper end of the weighbridge sensor assembly abuts against a higher position of the bottom surface of the first boss, thereby adjusting the overall descent of the weighbridge sensor assembly caused by the depression at the connection between the bottom of the weighbridge sensor assembly and the ground, resulting in a change in the sensor pressure of the weighbridge sensor assembly, so that the initial value of the sensor pressure of the weighbridge sensor assembly returns to the factory setting and maintains the measurement accuracy.

[0021] By adjusting the contact part between the first boss and the upper end of the weighbridge sensor assembly, the initial pressure values of each sensor point can be balanced, thereby balancing the pressure distribution of the entire detection system and making the measurement more accurate.

Specific embodiments

[0029] The technical solution of the present invention will be further described below through embodiments and in conjunction with the drawings.

[0030] As Figures 1 - 6 shown, an adjustment assembly for a dynamic vehicle scale (the dynamic vehicle scale is the abbreviation of a dynamic highway vehicle automatic scale) includes a first adjustment block 3. As Figure 4 shown, the first adjustment block 3 includes a chassis 31, a second boss 33 located at the upper end of the chassis 31, and a first boss 32 located at the lower end of the chassis 31. The chassis 31 is a disc-shaped structure, and the chassis 31, the second boss 33, and the first boss 32 are coaxially arranged. The first boss 32 extends vertically downward along the bottom surface of the chassis 31 to form a protrusion. The bottom surface of the first boss 32 is an inclined surface, and the diameter of the first boss 32 is smaller than that of the chassis 31. The second boss 33 extends vertically upward along the top surface of the chassis 31 to form a protrusion. The second boss 33 is a cylindrical structure, and the diameter of the second boss 33 is smaller than that of the chassis 31. As Figure 2 , 5 shown, the second boss 33 is provided with a first groove 331. The first groove 331 is recessed downward along the upper end surface of the second boss 33 to form a rectangular groove with a rectangular cross-section.

[0031] As Figure 3 , 6As shown in the figure, a second adjusting block 4 is provided above the first adjusting block 3. The first adjusting block 3 and the second adjusting block 4 are coaxially arranged. The second adjusting block 4 includes a pedestal 42 at the lower end and a top cap 41 at the upper end of the pedestal 42. The top cap 41 is a regular hexagonal structure. A first groove 411 is provided at the upper end of the top cap 41. The first groove 411 is a long strip groove, which is recessed downward along the upper end face of the top cap 41. The first groove 411 transversely penetrates a pair of side edges of the regular hexagon of the top cap 41. A magnet component 7 is detachably installed in the first groove 411. The magnet component 7 is snapped into the first groove 411 for installation. The size of the magnet component 7 matches that of the first groove 411. The bottom of the magnet component 7 is a magnet. The second adjusting block 4 is a metal part. After the magnet component 7 is snapped into the first groove 411, its bottom surface can be attracted to the bottom surface of the first groove 411 for fixation.

[0032] The pedestal 42 extends vertically downward along the lower end face of the top cap 41 to form a cylindrical structure. The pedestal 42 and the top cap 41 are coaxially arranged. The outer diameter of the pedestal 42 is smaller than the outer diameter of the top cap 41. A second groove 421 is provided at the center of the pedestal 42. The cross-sectional dimension of the second groove 421 is the same as that of the first groove 331. The first groove 331 and the second groove 421 are coaxially arranged. The second groove 421 penetrates the pedestal 42 up and down. The side length of the second groove 421 is greater than the width of the first groove 411. The upper end of the second groove 421 is connected to the first groove 411.

[0033] As Figure 3 shown in the figure, a connecting block 5 is slidably installed in the second adjusting block 4. The connecting block 5 is a cube structure. The cross-sectional dimension of the connecting block 5 matches both the first groove 331 and the second groove 421. A part of the connecting block 5 is located in the second groove 421. Specifically, the connecting block 5 is inserted into the second groove 421 from the bottom of the pedestal 42. The connecting block 5 can move up and down along the second groove 421. When the lower end of the connecting block 5 moves downward, it can be inserted into the first groove 331. When the connecting block 5 moves downward and extends into the first groove 331, the second adjusting block 4 can drive the first adjusting block 3 to rotate together.

[0034] After the magnet component 7 is installed, it can attract the connecting block 5. At this time, a part of the upper end face of the connecting block 5 is in contact with the bottom surface of the magnet component 7, so as to separate the connecting block 5 from the top of the second boss 33.

[0035] As Figure 1 shown in the figure, an installation structure of a dynamic truck scale adjusting component includes the above-mentioned dynamic truck scale adjusting component, and further includes a support plate 1. The support plate 1 is provided with a plurality of platform scale adjusting components. The support plate 1 is a cube structure. The platform scale adjusting components are installed at four corners of the support plate 1.

[0036] As Figure 2As shown in the figure, the second adjustment block 4 is threadedly connected and inserted into the upper end of the support plate 1, and the first adjustment block 3 is slidably connected and inserted into the lower end of the support plate 1. A counterbore 11 is provided at the bottom of the support plate 1, and the chassis 31 is located within the counterbore 11. The counterbore 11 includes a counterbore seat surface 111 at the upper end. The upper end surface of the chassis 31 fits against the counterbore seat surface 111. When a force is applied below the chassis 31, the chassis 31 transmits the force to the counterbore seat surface 111. The outer diameter of the chassis 31 is set to be relatively large, so the area of its upper end surface is relatively large to reduce the deformation generated when the force applied to it is relatively large.

[0037] The pillar 42 of the second adjustment block 4 is threadedly connected and inserted into the support plate 1. Before tightening, first install the magnet component 7 to separate the connecting block 5 from the top of the second boss 33. After tightening, the bottom position of the connecting block 5 is higher than the top position of the first adjustment block 3, and the bottom position of the pillar 42 is higher than the top position of the second boss 33. Since the magnet component 7 magnetically attracts and fixes the connecting block 5, when the pillar 42 is screwed in, the connecting block 5 will not be stuck in the first groove 331.

[0038] A plurality of weighbridge sensor assemblies 2 are provided below the support plate 1. A sensor is provided within the weighbridge sensor assembly 2, and its top is a sensor contact head. This sensor is a pressure sensor (a commonly used weighbridge detection sensor at present). The weighbridge adjustment assembly corresponds to the weighbridge sensor assembly 2 one by one. The bottom of the weighbridge sensor assembly 2 is installed on the ground 6, and the upper end of the weighbridge sensor assembly 2 abuts against the bottom surface of the first boss 32. The ground 6 is provided with a guide seat 8. The upper part of the weighbridge sensor assembly 2 is located within the guide seat 8, and the inner wall of the guide seat 8 fits against the outer wall of the weighbridge sensor assembly 2. The setting of the guide seat 8 enables the weighbridge sensor assembly 2 to only move up and down along the inner wall of the guide seat 8 when it moves.

[0039] The weight of the support plate 1 is shared and borne by four weighbridge sensor assemblies 2.

[0040] An adjustment method for a dynamic vehicle scale adjustment assembly includes the installation structure of the above-mentioned dynamic vehicle scale adjustment assembly, and further includes the following steps:

[0041] ① Remove the magnet component 7 to separate the connecting block 5 from the magnet component 7. The connecting block 5 falls freely and its lower end abuts against the upper end of the second boss 33.

[0042] ② Rotate the second adjustment block 4 in the direction of unscrewing the thread. When the bottom surface of the connecting block 5 rotates until it coincides with the first groove 331, the lower end of the connecting block 5 falls into the first groove 331.

[0043] ③ At the initial position, the upper end of the weighbridge sensor assembly 2 abuts against the highest point of the bottom surface of the first boss 32. Continue to rotate the second adjustment block 4 to rotate the first adjustment block 3, thereby driving the first boss 32 to rotate.

[0044] Since the weighbridge sensor assembly 2 has been detecting overweight and over-limit vehicles for a long time, the connection between its bottom and the ground surface is prone to slight depression, resulting in a downward movement of the overall position of the sensor assembly 2 and a change in the initial pressure value of the sensor in the sensor assembly 2, thereby increasing the measurement error. When detecting these weighbridges, the sensors with unqualified measurements are adjusted through the above-mentioned dynamic truck scale adjustment assembly. Since the highest point of the bottom surface of the first boss 32 is in contact with the upper end of the weighbridge sensor assembly 2, after rotating and adjusting the first boss 32, the higher part of the bottom surface of the first boss 32 abuts against the upper end of the weighbridge sensor assembly 2, and the height difference of the adjustment is exactly the height by which the sensor assembly 2 has dropped, so that the initial pressure value of the sensor returns to the factory setting. Thus, the influence caused by the depression at the connection between the weighbridge sensor assembly 2 and the ground is eliminated, and there is no need to disassemble the entire weighbridge for repair.

[0045] ④ Insert the magnet component 7. The bottom of the magnet component 7 is in contact with the bottom surface of the first groove 411 and sucks the upper end of the connecting block 5, so that the bottom of the connecting block 5 leaves the first groove 331 and the position of the bottom of the connecting block 5 is higher than the top of the second boss 33. Then tighten the second adjusting block 4.

[0046] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
