Abstract
The utility model relates to a technical field for the safe utilization of the path brake. The utility model comprises a safety detecting portion and a starting portion for controlling the open of a brake bar, wherein the safety detecting portion controls and connects with the starting portion by signals and comprises a sensor which is arranged either on a motor mechanical gear portion of the path brake or on a motor circuit and can detect the falling speed of the path brake, a CPU which can judge whether to execute the open of the brake for protection action or not by the signals transferred from the sensor, the singles of the sensor are connected with the CPU and the signals of the CUP control and connect with the starting portion. Due to the sensor which is arranged on the motor rotation shaft or the gear portion and can detect the falling speed of the path brake is adopted to detect the speed of the brake bar, the utility model avoids installing a supervisory instrument including a strip shape gas-bag or the like on the lower side of the brake bar for simplifying the installation and not disturbing by outer atmosphere, and the matter of machinery damage is inexistence. Compared with the conventional pressure electric wave protection device of smash defending vehicle, the protection device of the utility model has the advantages of low cost, simple installation, good dependability and long life time or the like.
Description
Technical field
The utility model relates to the technical field of banister safe handling, says that more specifically relating to a kind of restrictor bar that prevents pounds the fender guard of car.
Background technology
Traditional anti-protected mode of pounding car protection employing pressure electric wave; need be at the following strip shaped air sac of installing of restrictor bar; when restrictor bar is run into object; strip shaped air sac is extruded; compressed air push micro-switch is connected in the strip shaped air sac; produce guard signal, the starter gear that micro-switch is passed to the unlatching of control restrictor bar with guard signal is opened restrictor bar.According to the principle of work of pressure electric wave, have several shortcomings: 1, strip shaped air sac is installed on the restrictor bar, so the micro-switch in the strip shaped air sac can lose efficacy because of entering of rainwater.2, the installation of strip shaped air sac has increased the installation difficulty of restrictor bar, has reduced reliability.3, strip shaped air sac is subjected to external force or aging former thereby damage easily, and service life is shorter.
Summary of the invention
It is simple that technical problem to be solved in the utility model provides a kind of installation, is not subjected to the interference of external environment, do not exist the restrictor bar that prevents of physical damage problem to pound the fender guard of car.
The utility model comprises the actuating section that safety detection part, control restrictor bar are opened; safety detection part signal control linkage actuating section; it is characterized in that: described safety detection comprises that partly the signal that the sensor that can detect the banister falling speed on the electromechanics running part that is installed in banister or the motor circuit, energy transmit according to sensor judges whether to carry out the CPU that opens a sluice gate to protect action; sensor signal connects CPU, cpu signal control linkage actuating section.
Described sensor comprises that one is installed in the machine shaft of banister or the speed sensor on the connected mechanical transmission component.This sensor is directly passed to CPU with rotating speed of motor, and CPU judges according to default speed range, if the overshoot scope, CPU just judges that restrictor bar runs into obstacle, sends order and carries out to actuating section and open a sluice gate the protection action.
Described sensor comprises the displacement pickup on the connected mechanical transmission component on the machine shaft that is installed in banister.Use this sensor also will design the pitch time that detects shift transformation in CPU, calculate rotating speed of motor according to change in displacement and pitch time, all the other steps are with top described.
Described sensor comprises a current sensor on the motor circuit that is installed in banister.This sensor is directly passed to CPU with the electric current of motor circuit, and CPU judges according to default speed range, if the overshoot scope, CPU just judges that restrictor bar runs into obstacle, sends order and carries out to actuating section and open a sluice gate the protection action.
Described installation and measuring part also comprises the current sensor on the motor circuit that is installed in banister.This can play the effect of double insurance, as long as any the overshoot scope in the value of the speed of motor and electric current, CPU just judges that restrictor bar runs into obstacle, sends order and carries out to actuating section and open a sluice gate the protection action.
The utility model is owing to adopt the speed that the sensor detection restrictor bar that can detect the banister falling speed is installed on machine shaft, avoided at detecting devices such as the following installation of restrictor bar strip shaped air sacs, simplify installation, be not subjected to the interference of external environment, do not had the problem of physical damage.Traditional relatively pressure electric wave is anti-pounds the car fender guard, and this fender guard has advantages such as cost is low, simple installation, good reliability, long service life.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structured flowchart of the utility model embodiment;
Fender guard control flow chart among Fig. 2 the utility model embodiment.
The specific embodiment
Fender guard among the embodiment comprises the actuating section that safety detection part, control restrictor bar are opened; installation and measuring partly comprises two sensors; the signal that energy transmits according to sensor judges whether to carry out the CPU that opens a sluice gate to protect action; sensor signal connects CPU, cpu signal control linkage actuating section.Two sensors comprise that is mounted in the sensor that can detect the banister falling speed on the machine shaft, the current sensor on motor circuit that is installed in banister.The described sensor that is installed in motor (i.e. motor among the figure) rotating shaft is displacement pickup (as the Hall element of selling on the market).Use this sensor also will in CPU, design the pitch time that detects shift transformation; calculate rotating speed of motor according to change in displacement and pitch time; CPU judges according to default speed range; if overshoot scope; CPU just judges that restrictor bar runs into obstacle, sends order and carries out to actuating section and open a sluice gate the protection action.
Fender guard among the embodiment can play the effect of double insurance, as long as any the overshoot scope in the value of the speed of motor and electric current, CPU just judges that restrictor bar runs into obstacle, sends order and carries out to actuating section and open a sluice gate the protection action.
Brief description is the principle of work of fender guard in the present embodiment once.
When the normal barrier gate of banister, the value of the speed of the motor of banister and electric current all is in a scope each time, and when restrictor bar was run into obstacle, the speed of motor and the value of electric current can change.The variation of the speed by detecting motor and the value of electric current judges whether restrictor bar runs into obstacle, and when the speed of motor or the value overshoot scope of electric current, CPU just judges that restrictor bar runs into obstacle, carries out and opens a sluice gate the protection action.This design can realize that during the banister barrier gate, restrictor bar is after running into object, and action is opened a sluice gate in bounce-back immediately, avoids restrictor bar to pound car and causes damage.
