Abstract
The invention relates to a crane walking trolley with an ultrasonic wave anticollision device. The crane walking trolley with the ultrasonic wave anticollision device comprises a walking trolley (1). The crane walking trolley with the ultrasonic wave anticollision device is characterized by also comprising an ultrasonic wave ranging device (3) which is installed on the end part of the walking trolley (1) through an installation support (2), and comprises a main control chip, an ultrasonic wave emitting module, an ultrasonic wave receiving module, a data output module and a temperature compensation module. The crane walking trolley with the ultrasonic wave anticollision device can automatically monitor obstacles on a running track of a portal crane; when the distance between the crane and the obstacles is greater than the set safety distance, no action is generated; when the distance between the crane and the obstacles is less than the set safety distance, an alarming signal is sent out, and is transmitted to a driver cab and a PLC (programmable logic controller) through a data line, so that the crane reduces speed and is avoided timely, and the safety protection performance of the crane is increased.
Description
Technical field
The present invention relates to a kind of hoisting crane walking carriage, be specifically related to a kind of span winch walking carriage with the ultrasonic anti-collision device.Belong to the elevator machinery technical field.
Background technology
Span winch is rail operation type hoisting crane, and the effect of operating unit is the control position that changes span winch.In order to satisfy busy need of production, can arrange many span winch co-operation at the same track.In order to prevent the hoisting crane derailing, in rail end car bumper device can be set.
Before the present invention, conventional span winch walking carriage is not have the ranging for preventing collision function, and in operational process, co-orbital two span winchs move in opposite directions or hoisting crane the mutually danger of collision can occur when moving near the car bumper.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, a kind of span winch walking carriage with the ultrasonic anti-collision device is provided, the safety when improving the span winch operation.
The object of the present invention is achieved like this: a kind of hoisting crane walking carriage with the ultrasonic anti-collision device, and it comprises walking carriage, and it also comprises supersonic range finder, and described supersonic range finder is installed on the end of walking carriage by mounting bracket.
Described supersonic range finder comprises main control chip, super sonic transmitter module, super sonic receiver module, data outputting module and temperature compensation module.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention can monitor the obstacle on the span winch orbit automatically; when hoisting crane and obstacle distance attonity greater than the safety distance set the time; when hoisting crane and obstacle distance provide alarm signal less than the safety distance set the time; be delivered to driver's cab and PLC by data line; the timely reduction of speed of hoisting crane is dodged, increased the safety guard-safeguard performance of hoisting crane.
Description of drawings
Fig. 1 arranges schematic diagram with the span winch walking carriage of ultrasonic anti-collision device.
Fig. 2 is the crashproof schematic diagram of ultrasonic ranging.
Fig. 3 is pulse echo method range measurement principle figure.
Fig. 4 is the ultrasonic ranging system hardware structure diagram.
Wherein:
Supersonic range finder 3.
The specific embodiment
Referring to Fig. 1, the present invention relates to a kind of hoisting crane walking carriage with the ultrasonic anti-collision device, comprise walking carriage 1 and supersonic range finder 3, supersonic range finder 3 is installed on the end of walking carriage 1 by mounting bracket 2.
Can be found out by Fig. 2, Fig. 3, because the hypracoustic wavelength is short, easily obtain orientation and concentrated wave beam, when sending super sonic, projector begins timing, when receiving super sonic, receptor stops timing, thereby directly obtain the time t that super sonic is propagated in air, just can calculate the distance L that solves between measurement point and the tested obstacle.
As seen from Figure 4, supersonic range finder 3 comprises main control chip, super sonic transmitter module, super sonic receiver module, data outputting module and temperature compensation module.Main control chip operation super sonic transmitter module emission super sonic, super sonic is received by the super sonic receiver module after obstacle reflects, temperature when the temperature compensation module monitoring is measured also provides correction, then the time t that propagates in air according to super sonic of main control chip calculates the distance apart from obstacle, and with the safety distance of setting relatively, when hoisting crane and obstacle distance attonity greater than the safety distance set the time, when hoisting crane and obstacle distance less than the safety distance set the time, provide signal by data outputting module and be delivered to driver's cab and PLC, the timely reduction of speed of hoisting crane is dodged.
Claims (2)
1. hoisting crane walking carriage with the ultrasonic anti-collision device, it comprises walking carriage (1), it is characterized in that it also comprises supersonic range finder (3), described supersonic range finder (3) is installed on the end of walking carriage (1) by mounting bracket (2).
2. a kind of hoisting crane walking carriage with the ultrasonic anti-collision device according to claim 1 is characterized in that described supersonic range finder (3) comprises main control chip, super sonic transmitter module, super sonic receiver module, data outputting module and temperature compensation module.
