The utility model comprises a photoelectric switch (J) and a reflection board (F), wherein the photoelectric switch (J) is arranged on a travelling crane truck, and the reflection board (F) is installed on an adjacent travelling crane truck which is positioned at the same track. The utility model has the characteristics of simple structure and safety. A serious danger source on a travelling crane truck is eliminated fundamentally, and hidden safety troubles caused by using long pole cantilevers can also be eliminated when running limiting for travelling crane trucks is achieved.
Description
Technical field
The utility model relates to a kind of traffic safety device, especially a kind of driving cart safety inhibiting device.
Background technology
At present, stride three (containing two) with the factory of up train in use one, driving all need be installed mutual inhibiting device each other, to guarantee a driving when moving, approaching other driving when the operator does not note, but automatic train stop, to avoid collision, cause unnecessary safety misadventure.
Existing inhibiting device is normally installed travel switch (as the LX33 type) in a driving, correspondence position is installed a stock in the adjacent driving, in the travel switch in the driving of motion is bumped by the stock in the adjacent driving, can send powerdown signal, to reach spacing purpose, but because the driving running velocity generally can reach 0.5 meter per second, and when stopping, cannot braking suddenly, institute thinks anticollision, need at a distance of at least 0.7 meter the time, to cut off the power supply, add the security requirement of installation site, general spacing stock length is about 1.5 meters, Chang position-limited lever and will guarantee its flatness so, generally need select 8 bugle steel for use, and be suspended in this aerial root angle steel is the dangerous matter sources that driving increases in addition, and its shake when realizing that spacing reliability also can be split because of driving increases malfunctioningly, causes the generation of serious safety misadventures such as vehicle running collision.
Summary of the invention
The purpose of this utility model is to add a kind of driving cart safety inhibiting device that utilizes optoelectronic induction to realize non-direct contact of the existing potential safety hazard design of safe inhibiting device that travel switch is formed at the stock that existing driving is used.
The technical solution of the utility model is:
A kind of driving cart safety inhibiting device comprises photoelectric switch J, reflector F, it is characterized in that photoelectric switch J is installed on the driving cart, and reflector F is installed on another adjacent driving cart that is positioned on the same track.When the distance between the adjacent driving reached setpoint distance, photoelectric switch J received the signal that reflector F reflects, and triggered the outage that coupled control circuit is realized driving immediately, and this control circuit can adopt the circuit in the conventional textbook to be realized.
Described reflector F is installed on the adapter plate, the adjustable angle of adapter plate.
The utlity model has following advantage:
The utility model adopts photoelectric switch to carry out spacing simple in structure, the safe and reliable characteristics that have, fundamentally eliminated a major hazard source in the driving, when realizing that the driving large vehicle walking is spacing, can eliminate and adopt the caused potential safety hazard of stock cantilever.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a driving cart safety of the present utility model outage distance and the scheme drawing that concerns of reflector setting angle.
The specific embodiment
Following structure drawings and Examples are further described the utility model.
As shown in Figure 1, 2.
A kind of driving cart safety inhibiting device, comprise photoelectric switch J, reflector F, photoelectric switch J can select the photoelectric switch of Omron E3JK type band reflector for use, photoelectric switch J is installed on the driving cart H2, reflector F is installed on the adapter plate on another adjacent driving cart H2 that is positioned on the same track, and the adjustable angle of adapter plate is also fixing.When the distance between adjacent driving H1, the H2 reaches setpoint distance A, photoelectric switch J receives the signal that reflector F reflects, trigger the coupled actuating of relay immediately, make control circuit realize the outage of driving, this control circuit can adopt the circuit in the conventional textbook to be realized.
Photoelectric switch J also can be installed on the driving cart H1 during concrete enforcement, and corresponding reflector F also should be installed on the driving cart H2.
The photoelectric switch J and the reflector F group of pairing mutually also can all be installed at two ends of driving cart during concrete enforcement.Which platform driving to go up installation photoelectric switch J as for; which platform driving is gone up installation reflector F and then can optionally be determined; in addition, the installation site of photoelectric switch J and reflector F can be determined that also they all belong to protection of the present utility model field according to field condition.
The utility model also is applicable to the quantity of the driving on the same track more than three or three, and this moment is as long as install the safety device of being made up of photoelectric switch J and reflector F of the present utility model between two adjacent driving carts.
Therefore, no matter how installation site and the quantity on the driving cart of photoelectric switch J and reflector F change, they are all among protection domain of the present utility model.
Emitter window and the receiver window of the photoelectric switch J that present embodiment is selected are to distribute up and down, and the signal receiving range is non-adjustable, so if want to realize the adjustable of spacing distance of driving a vehicle, can be according to the specular reflection principle, reflector F is carried out the left rotation and right rotation adjustment, and, can reach the spacing function of driving through actual verification.The type selecting of photoelectric switch also can be selected by actual demand during concrete enforcement, and adapter plate is mainly used in installs reflector F, but and left rotation and right rotation, promptly need fix after putting in place.
Principle of work of the present utility model is:
The photoelectric switch J's of utilization band reflector F is untouchable, by the self-control adapter plate, photoelectric switch and reflector are installed in adjacent two drivings respectively, when the signal that sends of driving of motion can make contactless switch action outage by the reflector reflected back in the adjacent driving and after receiving, to reach the parking purpose.
As shown in Figure 1, 2, photoelectric switch J and reflector F are installed respectively at the left end correspondence position of two drivings H1, H2, reflector F adjust to require apart from the time can be as Fig. 2 in the direction rotation.Reflector F in Fig. 2 a, b) gyration is α, with the distance of photoelectric switch J be respectively A1 and A2,1. represent the line of departure, 2. represent reflected ray, just photoelectric switch J can receive reflected ray in Fig. 2 a, plays the outage effect, and at this moment A1 is the distance of driving H2 outage when driving H1 operation; In Fig. 2 a and Fig. 2 c, though the distance of photoelectric switch J and reflector F is A1, but reflector F anglec of rotation β＞α among Fig. 2 c, then photoelectric switch J can't receive reflected ray, has only as among Fig. 2 d, with the close more photoelectric switch J of reflector F, promptly shortening distance between the two is to A3, photoelectric switch J could receive reflected ray once more, thereby causes the actuating of relay that connects, and at this moment A3 is the distance of driving H2 outage when driving H1 operation; Move to H2 as H1, can corresponding photoelectric switch J and reflector F be installed respectively at the driving right-hand member.
As can be seen from Figure 2, the reflection angle difference of reflector F, the distance of its outage are also different, shown in Fig. 2 a, d.When the angle of reflector F during α in a certain setting, the distance of driving cart H2 and driving cart H1 can realize outage when becoming A1 by A2, that is to say, when the distance between the two during greater than A1, photoelectric switch does not receive the signal that reflector F returns, relay is failure to actuate, and the driving cart normally moves.
