Abstract

The utility model discloses a safe device for a bridge crane. The safe device for the bridge crane is characterized by comprising sensors, a controller and an alarm, wherein the sensors are respectively arranged at two ends of an end beam of the bridge crane; the controller is used for supplying power to the sensors, and processing signals feedback by the sensors; the sensors are ultrasonic sensors or radar sensors; and when a probed objected distance is less than a set distance, the alarm is turned on or stopping signals can be output. With the adoption of the safe device for the bridge crane, provided by the utility model, safe accidents caused by that the bridge crane collides staff can be avoided; and the equipment damage of the bridge crane, caused by that a rail end head limiting device is collided at a high speed or two bridge cranes on a same rail mutually collide, can be prevented. The safe device for the bridge crane, provided by the utility model, has the advantages of sensitive reaction, moderate effective range, small maintenance amount, convenience in debugging and the like.

Description

A kind of crane in bridge type safety device

Technical field

The utility model relates to weight-hauling equipment field, particularly a kind of crane in bridge type safety device.

Background technology

The crane in bridge type of widespread use is when work, because the driver can't see situation on large Car Track, there is following potential safety hazard: when (1) crane in bridge type is walked in orbit, if there is the people to stop on track girder, will cause the accident of hurting sb.'s feelings, this accident happens occasionally; (2) collision between hoisting crane can occur during many cars operation sometimes, cause hoisting crane to damage; (3) when reaching tail track, hoisting crane could not in time stop, the collision inhibiting device;

The safety device of existing crane in bridge type is on the track of tail track or on end carriage, energy disperser to be installed, and slows down the impact of hoisting crane.This device exists reliability not high, and maintenance is large, regulates the shortcomings such as difficult, and application is relatively poor.And this device can't detect personnel's existence, can not avoid the generation of casualty accident.

The utility model content

Technical problem to be solved in the utility model is to provide a kind of for above-mentioned the deficiencies in the prior art and is quick on the draw, debugs convenient and can avoid the crane in bridge type collision to cause the crane in bridge type safety device of safety misadventure.

The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be: 1, a kind of crane in bridge type safety device; it is characterized in that: it comprises sensor; controller, annunciator; described sensor is installed in the two ends of the end carriage of crane in bridge type; described controller provides power supply for sensor, and processes the signal that it returns, and described sensor is ultrasonic transduter or radar sensor; when the object distance that detects less than set apart from the time, start annunciator or output shutdown signal.

By technique scheme, described ultrasonic transduter or radar sensor are 4, are separately positioned on the two ends of two end carriages.

The obtained beneficial effect of the utility model is: the safety misadventure that the utility model can be avoided crane in bridge type collision personnel occur occurs, and can prevent crane in bridge type because of high-speed crash track termination inhibiting device or prevent that two crane in bridge type on same track from colliding the device damage that causes mutually; The advantages such as the utlity model has and be quick on the draw, efficient range is moderate, and maintenance is little, and debugging is convenient.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, 2, 3, be provided with sensor 2, controller 3, annunciator 4 on crane in bridge type 1.Described sensor is 4, be separately positioned on the two ends of two end carriages of crane in bridge type 1 and emitting surface mutually outside, whether the place ahead that each sensor can detect the crane in bridge type motion has personnel and object to exist.Described controller 3 is carried 2 power supply sources for sensor, and processes the signal that it returns, when the object distance that detects less than set apart from the time, start annunciator 4 or output shutdown signal.

Wherein, described sensor 2 is ultrasonic transduter or radar sensor.

Claims

1. crane in bridge type safety device; it is characterized in that: it comprises sensor; controller, annunciator; described sensor is installed in the two ends of the end carriage of crane in bridge type; described controller provides power supply for sensor, and processes the signal that it returns, and described sensor is ultrasonic transduter or radar sensor; when the object distance that detects less than set apart from the time, start annunciator or output shutdown signal.

2. a kind of crane in bridge type safety device according to claim 2, it is characterized in that: described ultrasonic transduter or radar sensor are 4, are separately positioned on the two ends of two end carriages.
