Problems solved by technology
[0004] Yet in actual construction site, the noise of construction is very big, and the sound alarm in the above-mentioned invention may be difficult to effectively remind the standing person under the boom; The light alarm in the above invention may also be difficult to effectively alert the person standing under the boom
In this way, the person standing under the boom will stand under the boom for a long time, and the timer involved in the above-mentioned invention will keep the hoisting control system of the crane in a locked state for a long time, and the crane cannot work normally

Embodiment Construction
[0042] Such as figure 2 , Tower crane safety control device, including: human body detection device 01, control device 02, sound and light alarm device 03, water spray device 04.
[0043] The human body detection device 01 is used to detect whether there is a person standing under the boom h, and the human body detection device includes at least one thermal infrared sensor arranged on the boom h.
[0044] The control device 02 is connected with each thermal infrared sensor signal, and is used for outputting an alarm signal when a person stands under the boom. The control device 02 is provided with a timer; the timer is connected to the hoisting control system 05 of the crane, and when a person stands under the boom h for a set duration, the control device outputs a hoisting locking control signal to the crane The hoisting control system of the crane controls the hoisting control system of the crane to be in a locked state. The timer is connected to the water pump. When a pe...

The invention discloses a safe control device of a tower type hoisting machine. The control device comprises a human body detection device, a control device, a sound-light alarm device and a water spraying device. The human body detection device is used for detecting whether a person stands below a cargo boom or not; the control device is in signal connection with each thermal infrared sensor and used for outputting alarm signals when the person stands below the cargo boom; the sound-light alarm device is connected with the control device and is used for giving out a sound alarm and a light alarm; the water spraying device is mounted on the cargo boom and is connected with the control device. According to the technical scheme, when the hoisting machine performs suspended load hoisting work, the human body detection device detects that the person stands below the cargo boom, the control device controls the sound and light alarm device, the sound-light alarm device sends out the sound alarm and the light alarm at the same time or successively, the control device enables the water spraying device to act, and the water spraying device sprays water to the person standing below the cargo arm. According to the water spraying device, the person standing below the cargo boom can be effectively reminded to leave, and safety of suspended load work is ensured.
Description
Technical field: [0001] The invention belongs to the technical field of hoisting machinery, and in particular relates to a safety control device of a tower hoisting machinery. Background technique: [0002] The jib is the direct load-bearing part of the crane when it is in the lifting or hoisting state. It has the characteristics of heavy weight, large size, long extension length and large hoisting load. When the staff stands under the jib, it is extremely difficult It is possible to be injured by falling heavy objects or broken booms, resulting in casualties. The manufacturer also printed safety reminder slogans on the boom to remind the staff. However, during the actual lifting operation of the crane, the staff often ignores the safety warning slogan involuntarily and stands under the boom, so there are still certain potential safety hazards. [0003] In view of the above technical problems, the invention with application number CN201320735289.2 discloses a boom safety c...
