Embodiment
Be described principle of the present utility model and feature below in conjunction with example, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
Embodiment 1, as depicted in figs. 1 and 2, a kind of Trailer axle offset detector, comprise the generating laser 1 be arranged in Trailer axle and the first sensor assembly be arranged between trailer crossbeam 2 and the second sensor module 3, described generating laser is arranged between described first sensor assembly and the second sensor module, described first sensor assembly comprises the first data acquisition module of electrical connection, first data conversion module, data processing module, wireless receiving module and display module, described second sensor module comprises the second data acquisition module of electrical connection, second data conversion module and wireless transmitter module, described first data acquisition module comprises first sensor, described second data acquisition module comprises the second sensor, first laser rays 4 of described generating laser backward launched is irradiated on first sensor, the second laser rays 5 that described generating laser is launched forward is irradiated on the second sensor, described first laser rays 4 and the second laser rays 5 are on same straight line.
Described generating laser 1 is arranged on the middle part of Trailer axle 6, described first sensor assembly is hung in the below of trailer two crossbeam 7 center line of described generating laser rear end by isoceles triangle support 8, and described second sensor module is by the below of the trailer two crossbeam center line of isoceles triangle support hanging in described generating laser front end.First, second sensor module can be made to be arranged on respectively on rear side of generating laser by isoceles triangle support and front side trailer two crossbeam centre positions immediately below, first, second sensor is facilitated to receive the irradiation of laser rays comprehensively and not block by vehicle bridge, and when generating laser is also arranged on vehicle bridge centre position simultaneously, whether vertically not only can measure between Trailer axle with crossbeam, there are how many side-play amounts, can also judge whether Trailer axle occurs left and right tandem bridge phenomenon, adopt this precision that installs and measures high, error is little.
Described sensor adopts cmos sensor.It is accurate that cmos sensor receives laser radiation data, and image data is convenient, fast, and its length can design as required, to reduce measuring error.
Namely the middle part that generating laser is arranged on Trailer axle can be arranged near vehicle bridge centre position or be directly installed on vehicle bridge centre position, and first sensor assembly, second sensor module respectively by isoceles triangle support installing on rear side of generating laser and front side two crossbeam center lines immediately below, the first laser rays that generating laser sends is irradiated to first sensor, first sensor collects the position that the first laser rays is irradiated to first sensor, first data conversion module converts the data message of this position to numerical value, the second laser rays that generating laser sends is irradiated on the second sensor, second sensor collects the position that the second laser rays is irradiated to the second sensor, this position data is changed into numerical value by the second data conversion module, then the data message that the second sensor receives passes through wireless transmitter module, wireless receiving module is delivered to the data processing module of first sensor assembly, the data processing module of first sensor assembly is to the first sensor collected, second sensor carries out calculation process, the data of the vehicle bridge side-play amount after data processing module process directly read by display module.
As shown in Figure 4, for measuring state 1 structural representation of Trailer axle side-play amount, generating laser is arranged on the middle part of vehicle bridge, first, second sensor module is arranged on immediately below two crossbeam center lines respectively, the first laser rays that laser transmitter projects goes out, the second laser rays are respectively on the central point of first sensor and the second sensor, display module is shown as zero, illustrates that vehicle bridge is vertical with crossbeam; If generating laser is mounted in the centre position of vehicle bridge, then not only can illustrate that vehicle bridge is vertical with crossbeam, does not exist the side-play amount of vehicle bridge and crossbeam verticality, vehicle bridge is also described, and tandem bridge trailer vehicles is very unsafe.
As shown in Figure 5, for the structural representation of Trailer axle side-play amount measuring state 2, generating laser is arranged on the middle part of vehicle bridge, first, second sensor module is arranged on immediately below two crossbeam center lines respectively, the first laser rays that laser transmitter projects goes out and the second laser rays are at the homonymy of first, second center sensor point, and distance is the same, the distance of central point to laser rays drop point can be subtracted each other by data processing module, display module is shown as zero, draw the offset of zero of vehicle bridge and crossbeam verticality, then illustrate that vehicle bridge is vertical with crossbeam; If generating laser is just in time arranged on the centre position of vehicle bridge, although then illustrate that vehicle bridge is vertical with crossbeam, there is not skew in vehicle bridge, tandem bridge phenomenon has appearred in vehicle bridge, first laser rays or the second laser rays represent vehicle bridge tandem bridge amount to the distance of central point, so also there will be tire wear.
As shown in Figure 6, for the structural representation of Trailer axle side-play amount measuring state 3, if the drop point of the first laser rays of generating laser and the second laser rays is respectively when the both sides of first sensor, the second center sensor point, the distance of central point to laser rays drop point can be added by data processing module, and the data drawn are exactly the side-play amount of vehicle bridge and crossbeam verticality.
As shown in Figure 7, for the structural representation of Trailer axle side-play amount measuring state 4, if the first laser rays that generating laser is launched, the drop point of the second laser rays are respectively in the same direction of first sensor, the second center sensor point, but distance is different, data processing module long distance can be adopted to deduct data that short distance draws are exactly the departure of vehicle bridge and crossbeam verticality.
Embodiment 2, as shown in Figure 3, described generating laser is arranged on the wheel hub of tire 9 of Trailer axle one end, and described first sensor assembly is arranged on the first support bar 10 of trailer crossbeam, and described second sensor module is arranged on the second support bar 11 of trailer crossbeam.Generating laser is by tire fixture or be adsorbed onto on the hub plane of tire with magnet, and all the other structures are identical with embodiment 1, and measuring principle is not going to repeat with embodiment 1.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
