Specific embodiment
The application is described in further detail with reference to the accompanying drawing, it is necessary to it is indicated herein to be, implement in detail below Mode is served only for that the application is further detailed, and should not be understood as the limitation to the application protection scope, the field Technical staff can make some nonessential modifications and adaptations to the application according to above-mentioned application content.
In conjunction with shown in Fig. 1 and Fig. 4, a kind of fork truck braking distance measuring tool, including detection wheel 1, installing mechanism, photoelectricity are opened Pass 2 and counter 3, detection wheel 1 are mounted on fork truck by installing mechanism, are typically chosen in forklift fork arm carrier, and detection wheel 1 Ground, detection wheel 1 is interior to be equipped with evenly distributed spoke 4, and optoelectronic switch 2 is located at the side of detection wheel 1, for detecting each spoke 4 Signal when passing through, counter 3 are electrically connected with optoelectronic switch 2, for receiving the detection signal of optoelectronic switch 2, and are recorded through light 4 quantity of spoke that electric switch 2 detects.
Structure as one embodiment, installing mechanism are made of pinboard 6, swing arm 7, shock-absorbing arms 8 and connector 9, switching Plate 6 is vertically installed in the fork carriage of fork truck, and 7 one end of swing arm is movably connected in 6 lower end of pinboard, the other end by connector 9 The two sides and end of wheel 1 are connect by wheel shaft with detection wheel 1 after testing, and 8 one end of shock-absorbing arms is flexibly connected by connector 9 In 6 upper end of pinboard, the other end is movably connected in the middle position of swing arm 7 by connector 9.
Optoelectronic switch 2 is mounted on the side of swing arm 7, and detection direction is laterally toward interior, alignment spoke.Shock-absorbing arms 8 have the body of rod and Damping spring composition, connector 9 are made of mounting rack and shaft.Pinboard 6, swing arm 7 (a part) and shock-absorbing arms 8 constitute One triangular structure, after installation, detection wheel 3 lands, and damping spring is in certain compressive state, guarantees detection Wheel 3 is adjacent to ground always during the driving of the forklift, does not dally.
Structure as one embodiment, as shown in connection with fig. 2, the top and bottom end of pinboard 6 are equipped with the bending towards the same side Corner plate 10, curved edges gusset 10 are made of arc plate 101 and plate 102, plate 102 and the tangent connection of arc plate 101.Switching Angle between 102 place plane of plate 6 and plate is 15 ° -25 °, and optimal is 20 °, and such pinboard 6 only need to be in fork carriage Assembly and disassembly can be realized in transverse shifting, more convenient.
Structure as one embodiment, as shown in connection with fig. 3, pinboard 6 are made of upper plate body 601 and lower body 602, lower plate The top of body 602 is equipped with slot board 603, and 601 activity of upper plate body is inserted in slot board 603, and is equipped in the side of slot board 603 Fixed pin 604.By adjusting grafting height of the upper plate body 601 in slot board 603, the width tune up and down to pinboard 6 is realized Section, and be tightened by fixed pin 604, it can be mounted in the fork carriage of different height, and guarantee that detection wheel 1 sufficiently connects Tread surface.
In addition, counter 3 is electrically connected with the braking microswitch 5 of fork truck, and counter is also equipped in conjunction with shown in Fig. 4 and Fig. 5 Power supply.When needing to detect, fork truck is first driven into maximum speed, then brake pedal, while brake pedal, Microswitch 5 to be braked to trigger, this hour counter 3 starts counting, and optoelectronic switch 2 often detects that a spoke passes through, it counts once, Until fork truck is static, fork truck braking distance can be calculated according to the number shown on counter 3 at this time.
For example, the number that counter 3 is shown is 300, then the height on 1 wheel base ground of detection wheel is measured (due to bearing a heavy burden not Together, the compressional deformation amount of tire is different, so need to re-measure every time to improve precision), it is assumed that axle articulation is measured as 0.2m, all spoke quantity of detection wheel 1 be 20, then in detection wheel 1 every adjacent spoke 4 it is corresponding actually rolled on wheel face away from From 20 ≈ 0.063cm of the ÷ of 2 × π × 0.2, then obtaining total braking distance multiplied by 300 is 18.9m, judge the braking of 18.9m away from From whether qualified.Certainly, it can also directly be counted by comparing counter to determine whether qualification, such as counter are counted as 350 It is considered as qualification below.
In addition, it is necessary to explanation, since there may be between an adjacent spoke at a distance from detection for active braking distance Error away from respective distances, for example, it is above-mentioned measure distance be 18.9m, active braking distance may be (18.9-0.063) m with Between (18.9+0.063) m range.So in detectable range, the spacing between spoke 4 is smaller when manufacture detection wheel 1, Detection accuracy is higher.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously Limitations on the scope of the patent of the present invention therefore cannot be interpreted as.It should be pointed out that for those of ordinary skill in the art For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention Protect range.
