Abstract
The utility model relates to an anticollision device for bridge cranes, which comprises a cart body, a PLC (Programmable Logic Controller), laser probes, reflecting plates, contact plates and stop limits and is characterized in that the laser probes, the reflecting plates, the contact plates and the stop limits are arranged corresponding to those of an adjacent bridge crane; output signals of the laser probes and the stop limits are respectively connected with the input terminal of the PLC; and the output terminal of the PLC is connected with a cart driving motor through a frequency converter. When two adjacent bridge cranes provided with the anticollision devices exceed the safe distance, the laser probes are triggered and are treated by the PLCs to enable the cart driving motors to run at a low speed; and when the stop limits are triggered, the cart driving motors are stopped by the PLCs and brake at the same time, so that the bridge cranes stop after sliding for an extremely short distance under the action of inertia. Therefore, a plurality of bridge cranes can be not only enabled to work closely according to production requirement, but also ensured safe operation.
Description
Technical field
The utility model relates to anticollision device, is a kind of crane in bridge type anticollision device specifically.
Background technology
Crane in bridge type is the visual plant in the cold rolling production, main reception raw material, unit material loading, discharging, the product car-loading etc. be responsible for.Need owing to produce, not only need many crane in bridge type to step up operation, and require adjacent crane in bridge type in operation, to lean on very closely same, so collision mutually easily in the operational process.Prior art is for guaranteeing safety, or the safety distance of adjacent crane in bridge type is set in more than the 10m, or only arranges the separate unit crane in bridge type at setting, often causes that finished product is detained, logistics is smooth, production efficiency is low.Therefore design a kind of allow the closely operation of adjacent crane in bridge type, can guarantee that the crane in bridge type anticollision device of safe operation is very necessary again.
Summary of the invention
The purpose of this utility model provide a kind of allow the closely operation of adjacent crane in bridge type, can guarantee the crane in bridge type anticollision device of safe operation again.
For achieving the above object, the utility model adopts following technical scheme: a kind of crane in bridge type anticollision device, comprise the cart vehicle body, be installed in the PLC on the cart vehicle body, the front end laser probe, the rear end laser probe, the front end reflecting plate, the rear end reflecting plate, the front end touch panel, the rear end touch panel, the front end parking limit and the rear end parking limit, it is characterized in that described front end laser probe is arranged on the front end face of cart vehicle body the corresponding position of rear end reflecting plate with the adjacent crane in bridge type in the place ahead, described rear end laser probe is arranged on the aft end face of cart vehicle body the corresponding position of front end reflecting plate with the adjacent crane in bridge type in rear, described front end reflecting plate is arranged on the front end face of cart vehicle body the corresponding position of rear end laser probe with the adjacent crane in bridge type in the place ahead, described rear end reflecting plate is arranged on the aft end face of cart vehicle body the corresponding position of front end laser probe with the adjacent crane in bridge type in rear, described front end touch panel is arranged on the front end face of cart vehicle body the corresponding position of the parking limit, rear end with the adjacent crane in bridge type in the place ahead, described rear end touch panel is arranged on the aft end face of cart vehicle body the corresponding position of the front end parking limit with the adjacent crane in bridge type in rear, the described front end parking limit is arranged on the front end face of cart vehicle body the corresponding position of rear end touch panel with the adjacent crane in bridge type in the place ahead, the described rear end parking limit is arranged on the aft end face of cart vehicle body the corresponding position of front end touch panel with the adjacent crane in bridge type in rear, described front end laser probe, the rear end laser probe, the output signal of the front end parking limit and the rear end parking limit connects with the input end of PLC respectively, and the mouth of PLC connects the cart drive motor by frequency converter.
In the time that adjacent two crane in bridge type of the present utility model being housed above safety distance, laser probe is triggered, and handles through PLC, and the cart drive motor is moved with 1 grade of rotating speed 11m/min.Because the crane in bridge type coast that moves under 1 grade of rotating speed distance is extremely short, when the parking limit of its touch panel or the parking limit and adjacent crane in bridge type or touch panel contact, PLC stops operating the cart drive motor, the while brake sticking brake, and crane in bridge type stops after sliding minimum distance.So, both can allow the closely operation of many crane in bridge type according to producing needs, guaranteed safe operation again.
