Abstract

The utility model relates to a secure operating device of a high-rise building tower crane. In the technical proposal, a transmitter with an antenna and a sound box are fixed on a lifting hook; an image-voice collector is arranged on a gyro type camera fame; the gyro type camera fame is fixed on a coupling rod; and the coupling rod is linked with an automatic resetting hinge seat on the lifting hook. Because of the structure, the utility model increases the space and three-dimensional sense of the image, reduces the mistaken judgment of distance caused by the plane image, can be used for more clearly watching the possibility of obstructing the security in the object lifted and the surrounding environment, solves the problems that the tower crane operator can not see clearly the ground and each floor and the signals are poor after being obstructed in the high-rise building construction, helps the operator to improve the safety factor and to strengthen the modern management level, and is more helpful and more effective in particular under the conditions with poor lighting at night and poor sight on rainy days and foggy days.

Description

Skyscraper safety of tower crane handling device

Technical field

The utility model relates to the safety of tower crane handling device that uses on a kind of building ground.

Background technology

The skyscraper safety of tower crane handling device of Chinese patent 032226799 patent announcement, by gathering emitter, repeater-transmitter, receiver, monitoring device and audio amplifier are formed, collection emitter and audio amplifier are contained in the suspension hook place of tower crane, repeater-transmitter is installed on the coaster of tower crane arm, receiver and monitoring device are installed in the operator's compartment of tower crane, gather on the emitter pick up camera and acoustic pickup are housed, pick up camera connects projector and battery, gather on the transmitter house emitting antenna is arranged, gather emitter one side magnet is arranged, video output terminal is arranged on the receiver, the audiofrequency output terminal, channel switch, battery socket and receiving wire have read-out and acoustic pickup on the monitoring device.The image of this handling device collection is for getting a bird's eye view plane picture, and no space and three-dimension effect cause the erroneous judgement of distance easily, lifts by crane inaccurately, exists unsafe hidden danger.

Summary of the invention

The purpose of this utility model provides a kind of accurate, safe and reliable skyscraper safety of tower crane handling device that lifts by crane.

The purpose of this utility model is achieved in that the emitter and the audio amplifier that have antenna are fixed on the suspension hook, the video/audio collector is installed on the gyroscope type camera pedestal, the gyroscope type camera pedestal is fixed on the pitman, and pitman connects with the hinge seat that automatically resets on being fixed on suspension hook.

Because the utility model adopts said structure, increase the space and the three-dimension effect of image, reduce the distance erroneous judgement that plane picture causes, clearlyer see that the object that hung and object have or not with environment on every side and hinder safe may taking place.At the suspension hook flank movement or when moving downward with other object collision, linkage system can be flexible automatically, and pick up camera can remain under the 30--45 degree angle.Linkage system is moved in the horizontal direction can do when being hit and is horizontally rotated, the hinge seat that automatically resets after stopping to automatically restore to original position with linkage system, rotating, move to any position pick up camera all can be downward with certain angle, does not influence normal observation and visual custom.Solution sight line of tower crane operator and ground and each flooring in high-building construction is unclear, building intercepts the back poor signal, helps the operator to improve safety factor and strengthens the modern management level.Particularly in the night light deficiency, helped when rainy day, greasy weather, sight line was unclear bigger, more remarkable effect.

Description of drawings

Fig. 1 is a constructional drawing of the present utility model.

Automatically reset hinge seat, 3 pitmans, 4 image and voice collectors, 5 gyroscope type camera pedestals, 6 antennas, 7 audio amplifiers, 8 emitters of 1 suspension hook, 2 among the figure.

The specific embodiment

Embodiment: the emitter 8 and the audio amplifier 7 that have antenna 6 are fixed on the suspension hook 1, video/audio collector 4 is installed on the gyroscope type camera pedestal 5, pick up camera and acoustic pickup are housed on the emitter 8, emitter 8 is equipped with battery, leave transmitter antenna Connection Block and frequency select switch on the shell, for connecting antenna 6 and selecting frequency to use, magnetic chuck is connected the bottom or the side of shell, gyroscope type camera pedestal 5 is fixed on the pitman 3, and pitman 3 connects with the hinge seat 2 that automatically resets on being fixed on suspension hook 1.

By pitman 3 video/audio collector 4 is extended to several meters outer sides, the image of taking is 30-miter angle, overcome the plane picture of getting a bird's eye view of original device fully, increase the space and the three-dimension effect of image, reduce the distance erroneous judgement that plane picture causes, clearlyer see that the object that hung and object have or not with environment on every side and hinder safe may taking place.At suspension hook 1 flank movement or when moving downward with other object collision, pitman 3 can be flexible automatically, and it is downward that pick up camera can remain 30-miter angle; Pitman 3 moves in the horizontal direction can do when being hit and horizontally rotates, the hinge seat 2 that automatically resets after stopping to automatically restore to original position with pitman 3, do not influence the visual custom of normal observation, particularly tower crane arm elongation, hanging object is when the ground on building opposite, the operator can't see ground object and environment at all, can be by this device at operator's compartment by clearer hanging object and the environment on every side of monitoring of monitor screen, and can note the object that hung with ground staff conversation and tip ground personnel timely by intercom system, reach the purpose of safety in production.When working at night or during rain, snow, greasy weather work,, can not seeing hanging object because the building high-visibility is poor, at this moment can see object and surrounding environment clearly by this device, improved the level of safety factor and management.

Claims

1, a kind of skyscraper safety of tower crane handling device, the emitter and the audio amplifier that have antenna are fixed on the suspension hook, it is characterized in that: the video/audio collector is installed on the gyroscope type camera pedestal, the gyroscope type camera pedestal is fixed on the pitman, and pitman connects with the hinge seat that automatically resets on being fixed on suspension hook.
