Abstract
The utility model relates to a crane traveling trolley with an ultrasonic anticollision device. The crane traveling trolley with the ultrasonic anticollision device comprises a traveling trolley (1), and is characterized by also comprising an ultrasonic distance measurement device (3), wherein the ultrasonic distance measurement device (3) is arranged at the end of the traveling trolley (1) through a mounting bracket (2) and comprises a master control chip, an ultrasonic transmitting module, an ultrasonic receiving module, a data output module and a temperature compensation module. Obstacles on a running track of a gantry crane can be automatically monitored, when a distance between the crane and the obstacles is greater than a set safety distance, no action is executed, and when the distance between the crane and the obstacles is smaller than the set safety distance, an alarm signal is given and transmitted to a driver's cab and a PLC (Programmable Logic Controller) through a data line, so that the crane is timely reduced and avoided, and a safety protection performance of the crane is improved.
Description
Technical field
The utility model relates to a kind of hoisting crane walking carriage, is specifically related to a kind of span winch walking carriage that has the super sonic anticollision device.Belong to the elevator machinery technical field.
Background technology
Span winch is a rail operation type hoisting crane, and the effect of operating unit is the control position that is used for changing span winch.In order to satisfy busy production needs, on same track, can arrange many span winch co-operation.In order to prevent the hoisting crane derailing, car bumper device can be set in rail end.
Before the utility model, conventional span winch walking carriage is not have the crashproof function of range finding, and in operational process, co-orbital two span winchs move in opposite directions or hoisting crane the danger of collision each other can take place when moving near the car bumper.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of span winch walking carriage that has the super sonic anticollision device is provided, the safety when improving the span winch operation.
The purpose of the utility model is achieved in that a kind of hoisting crane walking carriage that has the super sonic anticollision device, and it comprises walking carriage, and it also comprises supersonic range finder, and said supersonic range finder is installed on the end of walking carriage through mounting bracket.
Said supersonic range finder comprises main control chip, ultrasonic emitting module, super sonic receiver module, data outputting module and temperature compensation module.
Compared with prior art, the beneficial effect of the utility model is:
The utility model can be monitored 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 through 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 is that the span winch walking carriage that has the super sonic anticollision device is arranged scheme drawing.
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 utility model relates to a kind of hoisting crane walking carriage that has the super sonic anticollision device, comprises walking carriage 1 and supersonic range finder 3, and supersonic range finder 3 is installed on the end of walking carriage 1 through mounting bracket 2.
Can find out by Fig. 2, Fig. 3; Because the hypracoustic wavelength is short; Obtain orientation easily and concentrated wave beam picks up counting when projector sends super sonic, stop timing when receptor receives super sonic; 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.
Can find out that by Fig. 4 supersonic range finder 3 comprises main control chip, ultrasonic emitting module, super sonic receiver module, data outputting module and temperature compensation module.Main control chip operation ultrasonic emitting module emission super sonic; Super sonic is received by the super sonic receiver module after obstacle reflects; Temperature when temperature compensation module monitoring is measured also provides correction, and the time t that in air, propagates according to super sonic of main control chip calculates the distance apart from obstacle then, 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 the time less than the safety distance set, provide signal through 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 that has the super sonic anticollision device; It comprises walking carriage (1); It is characterized in that it also comprises supersonic range finder (3), said supersonic range finder (3) is installed on the end of walking carriage (1) through mounting bracket (2).
2. a kind of hoisting crane walking carriage that has the super sonic anticollision device according to claim 1 is characterized in that said supersonic range finder (3) comprises main control chip, ultrasonic emitting module, super sonic receiver module, data outputting module and temperature compensation module.
