An anti-collision system for a bridge erecting machine

Abstract

The invention discloses an anti-collision system for a bridge erecting machine, which includes a main controller for diagnosing collision faults and sending alarms and motion instructions; a data collection mechanism connected to the main controller through a CAN bus for collecting The position, speed and displacement signals of legs, middle outriggers, rear outriggers, temporary outriggers, hoist and crane are sent to the main controller; the industrial computer is connected with the main controller to receive the signals sent by the main controller The signal is monitored in real time, and the emergency braking command is sent to the main controller; the drive control mechanism is connected with the main controller to receive the movement command sent by the main controller, and the front outrigger, middle outrigger, rear outrigger, The motion control and drive of temporary outriggers, winches and cranes; the alarm device is connected with the main controller to receive the danger alarm instructions sent by the main controller and send out an alarm. Specially designed for bridge erecting machines, it has the characteristics of safety, reliability, fast response and strong real-time performance.

Description

technical field [0001] The invention belongs to the technical field of crane safety protection, and in particular relates to an anti-collision system for a bridge erecting machine. Background technique [0002] The bridge erecting machine is a kind of bridge crane, which is specially used to hoist the prefabricated reinforced concrete box girder to the bridge pier. Because of the high efficiency of the bridge erecting machine, it is widely used in the bridge construction of railways and highways. The main working process of the bridge erecting machine is as follows: the bridge erecting machine first uses temporary outriggers and rear outriggers to support, moves the front outrigger to the next pier and fixes it, and supports the front of the main girder together with the middle outrigger at the previous pier. After the main girder moves forward and is in place, it is supported by the rear outriggers, and the front and middle outriggers are released in turn, and the main gird...

AI Technical Summary

Problems solved by technology

[0005] The first is that the structure of the bridge erecting machine is different from that of ordinary bridge erecting machines. The front outriggers, middle outriggers, rear outriggers and temporary outriggers of the bridge erecting machine run on the same track. The above invention lacks different devices on the same track. anti-collision measures;

[0006] The second is that the above-mentioned inventions only limit the limit position of the cart and the trolley, but there is no limit speed limit measure, but when the speed of the cart and trolley is too fast, the braking distance becomes longer after the limit position is exceeded, which is also easy to occur. collision
