Description

A descending anti-collision protection device for a climbing avoidance device

technical field

The utility model relates to a downlink anti-collision protection device, in particular to a downlink anti-collision protection device for a climbing avoidance device in the field of wind power.

Background technique

Climb-free devices, a new type of wind turbine tower lifting equipment, are increasingly used. However, at present, climb-free devices usually do not have downlink anti-collision protection devices. Injury to personnel; the body of the climbing avoidance device is small and exquisite, and the mechanical structure is used to trigger the limit switch. The switch signal is sent to the receiver at the bottom of the tower to drive the motor to run. The wireless remote control is powered by a dry battery or a lithium battery. Limited by the battery power and voltage, it is not easy to use infrared or photoelectric sensors to detect obstacles, and it will be affected by the environment. Interference with temperature and light.

Contents of the invention

The purpose of this utility model is to provide a downlink anti-collision protection device for the existing technical deficiencies of the existing climbing avoidance device, which uses an ultrasonic sensor to detect in real time whether there is any damage within the set distance below when the climbing avoidance device body is descending. Once an obstacle or a person is detected, it can stop immediately, effectively protecting the safety of equipment and personnel, and the detection distance can be adjusted, with low power consumption and low price.

The downlink anti-collision protection device of the utility model comprises: a single chip microcomputer, an ultrasonic transmitting sensor, an ultrasonic receiving sensor, a remote controller, a receiver, a PLC controller, and a motor.

The single-chip microcomputer is installed on the car body of the climbing avoidance device, and is electrically connected with the ultrasonic transmitting sensor, the ultrasonic receiving sensor, and the remote controller. time, calculate the obstacle distance, and compare it with the detection distance set by the program. If it is within the detection distance, it means that there is an obstacle below, and output a switch signal to the remote control.

The ultrasonic transmitting sensor and the ultrasonic receiving sensor are installed side by side in the middle of the bottom surface of the pedal of the vehicle body of the climbing avoidance device, and are electrically connected with the single-chip electromechanical device.

The remote controller is installed on the car body of the climbing avoidance device, is electrically connected with the single-chip electromechanical device, receives the switch signal sent by the single-chip microcomputer, and sends the signal to the receiver.

The receiver is installed in the electric control box at the bottom of the tower, is electrically connected with the PLC controller, and receives signals transmitted by the remote controller.

The PLC controller is installed in the electric control box at the bottom of the tower, is electrically connected with the receiver, collects signals from the receiver, and controls the motor to run and stop.

The utility model uses an ultrasonic sensor to monitor the obstacle situation under the climbing avoidance device in real time, and converts the information into a switch signal and transmits it to the PLC controller in a wireless manner to control the motor to stop without touching the obstacle, effectively The safety of equipment and personnel is protected, and the detection distance can be adjusted by modifying the single-chip microcomputer program.

detailed description

As shown in Figures 1 and 2, the utility model includes a single-chip microcomputer 1, an ultrasonic transmitting sensor 2, an ultrasonic receiving sensor 3, a remote controller 4, a receiver 5, a PLC controller 6, and a motor 7.

As shown in Figure 2, the operation of the free climber is to rely on the motor 7 to drag the traction wire rope 9 to realize that the car body of the free climber runs up and down along the ladder 10. The single chip microcomputer 1, the ultrasonic transmitting sensor 2 and the ultrasonic receiving sensor 3 are installed on the vehicle The bottom surface of the body pedal is in the middle.

As shown in Figure 1, the single-chip microcomputer 1 and the remote control 4 are powered by the battery 8 on the body of the climbing avoidance device. The single-chip microcomputer 1 regularly controls the ultrasonic transmitting sensor 2 to send out a set of ultrasonic signals, and the ultrasonic signals are transmitted perpendicular to the pedals and directly below. , if there is an obstacle under the channel, the ultrasonic signal will be reflected back, and the ultrasonic receiving sensor 3 will receive the ultrasonic signal and send it to the single-chip microcomputer 1, and the internal program of the single-chip microcomputer 1 will calculate the obstacle and avoid climbing Compare the distance between the car body and the detection distance set by the program. If it is within the detection distance, it means that there is an obstacle below, and output the switching signal to the remote control 4; the remote control 4 transmits the switching signal wirelessly To the receiver 5 in the electric control box at the bottom of the tower, the PLC controller 6 collects the signal of the receiver 5, controls the motor 7 to stop, and will not touch obstacles. By modifying the internal program of the single-chip microcomputer 1, the obstacle detection can also be adjusted distance.
