Embodiment Construction

[0013] In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation manner.

[0014] First fix the measuring board on the tail of the forklift, use the laser rangefinder and the measuring board to collect the distance S between the measuring board and the laser rangefinder reference in real time during the braking process of the forklift moving at a constant speed at the maximum speed, decelerating and braking to stop The value is transmitted to the automatic calculation module of the braking distance in real time, and the automatic calculation module of the braking distance can measure the distance from the measuring board to the laser distance during the operation of the forklift under two different states of no-load and rated load collected in real time by the laser rangefinder. The instrument measures the distance S value of the reference, and obtains the function of S changing with time S=S(t)...

Abstract

The invention discloses a forklift brake distance detection method and device. The technical scheme is that the function of S varying with time, S=S(t), is obtained by adopting the laser ranger finder by virtue of the distance S value from a measurement plate to a measurement basis of a laser range finder in the process that a forklift moves in uniform motion at the maximal speed, then brakes in uniform deceleration until the forklift stops by utilizing a brake distance automatic calculation module according to the real-time collection; then automatic derivation of S(t) is carried out, thus the function of speed and time V=V(t) in the process that the forklift runs to the brake stopping at the maximal speed in uniform motion is obtained; and according to a speed function curve, the running speed V and braking time t in the braking process of the forklift in uniform motion can be obtained, wherein the brake distance automatic calculation module can obtain the braking distance S in braking according to a uniform deceleration motion distance formula. The brake distance automatic calculation module is connected with a printer, and data information and function curve patterns in the whole process can be printed in real time as required.

Description

technical field [0001] The invention provides a method and device for detecting the braking distance of a forklift. Background technique [0002] Forklifts are commonly used transport machinery in factories. Its braking distance is an important indicator related to the safety performance of forklifts. In the security inspection of the forklift, it is necessary to measure the braking distance of the forklift when the forklift is traveling at a constant speed from the maximum speed to the braking stop under the condition of no load and rated load. In actual production, it is necessary to check the braking distance of the forklift frequently to ensure safe production. According to the national standard, if the braking distance exceeds the range allowed by the standard, the forklift braking system needs to be repaired. Quickly and accurately measuring the braking distance of forklifts is an important means to improve the inspection efficiency and detection accuracy, but there...
