Abstract

A weighing platform for detecting the number of vehicle tires includes a weighing platform and narrow strip sensors. A vertical plate is provided at the upper end of the weighing platform, and a support plate is horizontally fixed to the outer side of the vertical plate. Several mounting plates, connected end-to-end, are mounted on the upper surface of the support plate. Each mounting plate is equipped with multiple narrow strip sensors, all arranged in a line to completely cover the upper weighing end. The narrow strip sensors are 210-230mm wide and 40-60mm long, with their top surfaces flush with the top surface of the weighing platform. This invention integrates the narrow strip sensors onto the weighing platform at the weighing end for detecting the number of tires on each axle of a vehicle. Each narrow strip sensor is independently installed, facilitating maintenance; replacement requires only individual replacement, saving costs.

Description

Technical Field

[0001] This utility model relates to the field of vehicle dynamic weighing technology, and in particular to a weighing platform with the function of detecting the number of vehicle tires. Background Technology

[0002] Currently, most devices used in the industry to identify vehicle axle information employ circular plate sensors. These sensors are arranged at regular intervals and installed within a rectangular housing, with segmented cover plates added so that the sensor contacts protrude a certain height from the cover plates. Installation involves carving grooves in the road surface and then casting epoxy resin into the grooves. If a sensor malfunctions or becomes abnormal, the entire system must be replaced, resulting in high maintenance costs. Furthermore, the small contact area between the circular plate sensor and the tire can lead to errors in tire count detection, reducing the recognition rate. Utility Model Content

[0003] In order to solve the above-mentioned problems in the prior art, the present invention provides a weighing platform with the function of detecting the number of vehicle tires.

[0004] This utility model is achieved through the following technical solution: a weighing platform with the function of detecting the number of vehicle tires, comprising a weighing platform and narrow strip sensors, characterized in that: a vertical plate is provided at the upper end of the weighing platform, a support plate is horizontally fixed on the outer side of the vertical plate, and several end-to-end mounting plates are mounted on the upper surface of the support plate, each mounting plate is equipped with multiple narrow strip sensors, and all the narrow strip sensors are arranged in a line to completely cover the upper end of the weighing platform; the width of the narrow strip sensor is 210-230mm, the length is 40-60mm, and the top surface of the narrow strip sensor is flush with the top surface of the weighing platform.

[0005] Furthermore, each of the mounting plates is equipped with two of the narrow strip sensors.

[0006] Furthermore, the narrow strip sensor has symmetrical mounting holes at both ends, and the mounting plate has corresponding threaded holes. The narrow strip sensor is fixed on the mounting plate by bolts passing through the mounting holes and threadedly connecting to the threaded holes.

[0007] Furthermore, the narrow strip sensor has a width of 220mm and a length of 50mm.

[0008] Furthermore, a reinforcing plate is provided below the support plate, and the reinforcing plate is fixed together with the upright plate and the support plate.

[0009] The beneficial effects of this utility model are:

[0010] 1. This utility model integrates narrow strip sensors on the weighing platform to detect the number of tires on each axle of a vehicle. Each narrow strip sensor is installed independently, making maintenance convenient. When replacing, only individual sensors need to be replaced, saving costs.

[0011] 2. By setting the support plate horizontally and using an appropriate mounting plate thickness, this utility model can not only ensure that all narrow strip sensors are located on the same plane, but also ensure that all narrow strip sensors are flush with the top surface of the weighing platform.

[0012] 3. In this utility model, every two narrow strip sensors share a mounting plate. When the wheel presses on the sensor, the planar contact rate between the sensor and the mounting plate is increased, thus extending the service life of the sensor. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1-5 The present invention will be described in detail with reference to specific embodiments.

[0020] like Figure 1-2As shown, a weighing platform for detecting the number of vehicle tires includes a weighing platform 1 and narrow strip sensors 2. A vertical plate 1-1 is provided at the upper weighing end of the weighing platform 1-1. A support plate 3 is horizontally fixed to the outer side of the vertical plate 1-1. Several mounting plates 4 connected end-to-end are mounted on the upper surface of the support plate 3. Each mounting plate 4 is equipped with two narrow strip sensors 2, and all the narrow strip sensors 2 are arranged in a line to completely cover the upper weighing end of the weighing platform 1. The narrow strip sensor 2 is 220mm wide and 50mm long, and its top surface is flush with the top surface of the weighing platform 1. The weighing platform 1 can be any type: whole vehicle type, axle group type, or modular type.

[0021] To facilitate the maintenance and replacement of each narrow strip sensor, mounting holes 2-1 are symmetrically provided at both ends of the narrow strip sensor 2, and threaded holes 4-1 are correspondingly provided on the mounting plate 4. The narrow strip sensor 2 is fixed on the mounting plate 4 by means of bolts 6 passing through the mounting holes 2-1 and threadedly connecting to the threaded holes 4-1.

[0022] To enhance the support strength and stability of the support plate 3, a reinforcing plate 5 is provided below the support plate 3, and the reinforcing plate 5 is fixed together with the upright plate 1-1 and the support plate 3.

[0023] The detection principle is as follows: in this embodiment, the narrow strip sensor has a length (perpendicular to the driving direction) of 220mm and a width (parallel to the driving direction) of 50mm. The tread width of existing vehicle tires is generally 200mm, and the spacing between dual tires is generally 50mm.

[0024] Figure 3-4 This is a schematic diagram illustrating the tire quantity detection principle for a single-tire vehicle. When the vehicle drives onto the upper end of the weighing platform 1, if the tread of tire 7 rolls over 3-4 narrow strip sensors 2, it is determined that there are 2 tires on the axle, indicating a single-tire axle.

[0025] Figure 5 This is a schematic diagram illustrating the tire quantity detection principle for dual-tire vehicles. When the vehicle drives onto the upper end of the weighing platform 1, if the tread of tire 7 rolls over 6 narrow strip sensors 2, it is determined that there are 4 tires on the axle, indicating a dual-tire axle.

[0026] Figure 6 This is a schematic diagram illustrating the tire quantity detection principle for dual-tire vehicles. When the vehicle drives onto the upper end of the weighing platform 1, if the tread of tire 7 rolls over 11 narrow strip sensors 2, it is determined that there are 8 tires on the axle, indicating a dual-axle configuration.

[0027] In actual operation, the narrow strip sensor 2 is connected to the host computer, and the force data of the narrow strip sensor 2 is transmitted to the host computer. Based on the received data, the host computer identifies the number of force-bearing narrow strip sensors, denoted by N. The specific determination method is as follows:

[0028] 1. When 2≤N≤4, the number of tires is 2, and it is determined to be a single-tire axle;

[0029] 2. When 5≤N≤10, the number of tires is 4, which is considered a dual-tire axle;

[0030] 3. When 10 < N, the number of tires is 8, which is determined to be a two-axle line.

[0031] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
