Description

Fork truck line ball detection device

Technical Field

The invention relates to the field of forklift test detection, in particular to a forklift line pressing detection device.

Background

At present, the evaluation of forklift items by special equipment operators mainly comprises two types of manual judgment and automatic judgment.

Manual judgment, wherein an appraiser is required to move along with the forklift for examination, the requirement on the concentration degree of the appraiser is extremely high, and judgment errors are easy to occur when the forklift has or does not have a pressure line; in addition, the forklift is always followed, so that certain dangers exist and fatigue is easily caused. Moreover, due to the arbitrary subjective judgment, there is a risk of intentional misjudgment or intentional strict judgment, which may seriously affect the credibility of the examination institution in the long run.

The automatic judgment is realized by mostly utilizing a satellite positioning technology to realize the line pressing judgment of the detection forklift, and the technology has the disadvantages that the differential base station and the satellite are very expensive in receiving price, and when the satellite signal is poor and the signal drifts, the wrong judgment often occurs, so that great troubles are caused to the correctness of the examination judgment. Moreover, when some examination rooms are arranged indoors, the technology is not used.

Therefore, a new testing device for forklift tests is needed to solve the problem.

Disclosure of Invention

The invention aims to solve the problems and provides a forklift line pressing detection device which is fair and fair in detection, judges whether a forklift presses a line or not by monitoring the color change of a photochromic coating, reduces the detection cost, improves the detection efficiency and ensures the safety and the fairness.

In order to achieve the purpose, the invention adopts the technical scheme that: a forklift wire pressing detection device comprises a library line mark, a forklift body and a balance connecting disc arranged at the center of wheels of the forklift body;

the laser emitter and the color sensor are arranged at the rear end of the forklift body and on the balance connecting disc in parallel;

the laser emitter and the color sensor are simultaneously connected to the vehicle-mounted computer, are arranged on the balance connecting disc in a balanced mode and work horizontally downwards;

the library line mark is provided with a photochromic coating layer.

Further, the balance connecting disc comprises an inner connecting disc and an outer fixing disc which are connected through a bearing, so that the outer fixing disc can not rotate along with the inner connecting disc and is independent of the inner connecting disc and the outer fixing disc.

Further, laser emitter and color sensor level are in parallel balanced arrangement outside the outer fixed disk, and the outer fixed disk both sides are equipped with the elasticity rope, and the elasticity rope is fixed with the fork truck body at the upside.

Specifically, the laser emitter and the color sensor act downward at the same position.

Further, the color sensor detects the color of the photochromic coating after changing color, so as to judge whether the forklift presses the line in the test process.

In summary, the invention has the following advantages:

1. the invention has the advantages of no need of manual monitoring in the detection process, low personnel participation, less uncontrollable factors and high safety.

2. The invention judges whether the forklift presses the line or not by monitoring the color change of the photochromic coating, and has the advantages of high detection stability, safety, convenience and low cost.

Detailed Description

The invention is further described with reference to the following figures and examples:

example 1:

a forklift wire pressing detection device is shown in figures 1-3 and comprises a library line mark 1 and a forklift body 2.

Specifically, the balance connection disc 3 at the wheel center of the forklift body 2 includes an inner connection disc 31 and an outer fixing disc 32, which are connected by a bearing, and the inner connection disc 31 is fixed with the wheel center.

The structural style of the balance connecting disc ensures that the outer fixed disc cannot rotate along with the inner connecting disc, thereby ensuring that the outer fixed disc cannot rotate along with the wheel.

With continued reference to fig. 3, the detection device further includes a laser emitter 4 and a color sensor 5, which are arranged in parallel at the rear end of the forklift body 2 and on the balancing connection disc 3.

Moreover, the laser emitter 4 and the color sensor 5 are horizontally arranged in parallel and balanced outside the external fixing disk 32, that is, the two disks ensure the balance of the external fixing disk, and certainly, the external fixing disk is not limited to a circular disk, and a rectangular bracket or other shapes can be adopted under the condition that the horizontal arrangement and balanced arrangement of the laser emitter 4 and the color sensor 5 are ensured.

In an application mechanism, the laser emitter 4 and the color sensor 5 are simultaneously connected to a vehicle-mounted computer and work horizontally downwards, and the laser emitter 4 and the color sensor 5 act on the same position downwards.

The laser emitter 4 is the laser emitter of specific wavelength, acts on the photochromic coating layer that is equipped with on the position mark 1 of storehouse and makes it discolour, and photochromic coating layer can discolour for the laser irradiation back at laser emitter 4's specific wavelength promptly, and color sensor 5 detects photochromic coating discolour back colour to judge whether the line ball is pressed to fork truck in the process of examining.

Further explanation is provided in connection with its examination detection mechanism:

when an examination is started, the vehicle-mounted computer gives an instruction, the laser emitter 4 emits pulse laser to irradiate downwards, the photochromic coating layer is changed in color under the irradiation of the laser with the specific wavelength, for example, the photochromic coating layer is changed from yellow to red, the color sensor alarms after detecting the specific color, a signal is given, and the vehicle-mounted computer receives the signal and judges the line pressing.

And the photochromic coating layer can not change color under common illumination, and the misjudgment rate is low.

It should be noted that the laser emitter, the color sensor and the photochromic paint are easily available on the market, and are not described in detail herein.

Example 2:

this implementation is further optimized on embodiment 1's basis, is equipped with elasticity rope 6 in two sides of outer fixed disk 32, and elasticity rope is fixed at upside and fork truck body 2, and this setting can play an supplementary fixed spacing effect to outer fixed disk, prevents to cause the rotation influence because of the excessive maloperation of examinee.

To sum up, this scheme detects fairly just, and through the colour change of monitoring photochromic coating, judges whether fork truck pushes line, has reduced detection cost, has improved detection efficiency to security and fairness have been guaranteed.
