Description
Technical field:
The invention belongs to elevator machinery technical field, in particular to a kind of safety control of tower crane tool.
Background technology:
The direct load bearing component that crane arm is hoisting crane when hoisting or hang the state of carrying, it has Heavy Weight, size is large, extension elongation is long and hang the large feature of year load, when staff stands in below crane arm, very likely occur being injured by a crashing object by the crane arm of the weight that drops or fracture and causing the situation of casualty accident, therefore, clear stipulaties " forbid under crane arm stand people " in National Standard of the People's Republic of China and industry standard, the manufacturer of hoisting crane has also printed safety prompt function poster to remind staff on crane arm.But hoisting crane carries in operation in hanging of reality, and staff often independently not have ignored this safety prompt function poster, and under having stood in crane arm, therefore still there is certain potential safety hazard.
For above-mentioned technical matters, application number be the disclosure of the invention of CN201320735289.2 a kind of crane arm safety control system and hoisting crane.Described crane arm safety control system, comprising: human body detection device, for detecting the people that whether to stand below crane arm; Control setup, is connected with described human body detection device signal, for stand below crane arm people time, output alarm signal; Acoustic-optic alarm, is connected with described control setup signal, sounds report to the police and light warning according to described alerting signal.Stand below crane arm people time, acoustic-optic alarm sends the audible alarm distinguishing nerve and light warning that are more prone to stimulate human body, personnel below prompting crane arm leave, therefore, it is possible to more effectively remind the personnel below crane arm to leave, to improve the safety of hanging and carrying operation.
But in practice of construction place, the noise of construction is very large, the audible alarm in foregoing invention may be difficult to effectively to remind the people that stands under crane arm; In addition, the operation that construction site is carried out generally is carried out by day, and under irradiation by sunlight, the light warning in foregoing invention also may be difficult to effectively to remind the people that stands under crane arm.So, under the people that stands under crane arm will stand on crane arm for a long time, the time meter involved by foregoing invention is in the lock state making the borne control system that hangs of described hoisting crane for a long time, and hoisting crane cannot normally work.
Summary of the invention:
Technical matters solved by the invention: hoisting crane of the prior art, the acoustic-optic alarm that it is installed the people that stands under noisy construction site may be difficult to effectively to remind crane arm leave, and then be difficult to ensure to hang the safety of carrying operation.
For above-mentioned technical matters, the invention provides following technical scheme: a kind of tower crane tool safety control, comprising:
Human body detection device, for detecting the people that whether to stand below crane arm, described human body detection device comprises at least one thermal infrared sensor be arranged on crane arm;
Control setup, is connected with each thermal infrared sensor signal, for stand below crane arm people time, output alarm signal;
Acoustic-optic alarm, is connected with described control setup, for warning and the light warning of sounding;
Water injecting system, described water injecting system is arranged on crane arm, water injecting system comprises water tank, water pump, water-supply-pipe, water injection valve, water injection valve fixed link, described water pump joining water box, water pump is connected with control setup, and control setup controls the startup of water pump, described water-supply-pipe is connected with water pump, described water injection valve is arranged on water-supply-pipe, and water injection valve is communicated with water-supply-pipe, and described water injection valve is fixed on water injection valve fixed link.
By technique scheme, when hoisting crane hangs and carries hoisting operation, whether stand below human body detection device detection crane arm people, and the information of the people that whether stands is sent to control setup, stand below crane arm people time, control setup output alarm signal is to acoustic-optic alarm, and acoustic-optic alarm is sounded and reported to the police and light warning, and the personnel below prompting crane arm leave; Acoustic-optic alarm sound warning and light warning while or afterwards, control setup sends actuation signal to water pump, water pump action, the water in water tank is delivered to water-supply-pipe by water pump, and the water in water-supply-pipe is sprayed to the people that stands below crane arm by water injection valve.
By technique scheme, when the audible alarm that acoustic-optic alarm sends and light warning cannot effectively to remind because of the condition restriction of workyard to stand people below crane arm time, or the people that stands below crane arm is subjective when not leaving because of other reasons, described water injecting system can remind the people that to stand below crane arm to leave effectively, to ensure to hang the safety of carrying operation.
Need stress, described water injecting system downwards the state of water of spraying belong to fine mist and so on, but not the large stock current of person health of standing below crane arm may be hurt.
Illustrate the one of water injection valve in water injecting system as the present invention, described water injection valve comprises valve body, anti-drip device, shower nozzle, clamping apparatus.Described valve body comprises feed liquor chamber, fluid chamber, liquid outlet channel, liquid outlet, described feed liquor chamber cylindrically, described fluid chamber is cylindric, the line of centers of cylindric feed liquor chamber overlaps with the line of centers of columned fluid chamber, one end face of feed liquor chamber and an end face of fluid chamber and outstanding valve body, the other end of feed liquor chamber and the other end of fluid chamber are closed, and liquid outlet channel is communicated with fluid chamber and liquid outlet; The sidewall of described valve body is provided with a pair threaded line pipe, and the line of centers of this double thread pipe overlaps, and this double thread pipe divides the both sides being listed in valve body, and this double thread pipe is communicated with, this double thread pipe and feed liquor chamber.Described anti-drip device comprises antidrip cavity, diaphragm, elastomeric composition part, described antidrip cavity is screwed onto on valve body, described diaphragm and elastomeric composition part are positioned at antidrip cavity, elastomeric composition part acts on an end face of diaphragm, and the other end of diaphragm is close on the end face that feed liquor chamber and fluid chamber flush.Described shower nozzle is arranged on valve body, and shower nozzle is communicated with liquid outlet.Described clamping apparatus is located at the top of valve body, clamping apparatus comprises upper fastener and lower fastener, upper fastener is offered first circular draw-in groove, lower fastener is offered the lower semi-circular draw-in groove that draw-in groove circular with first is relative, first circular draw-in groove and lower semi-circular draw-in groove form a bayonet socket, lower fastener is located on valve body, the side of upper fastener and the side of lower fastener hinged, the opposite side of upper fastener and the opposite side of lower fastener are provided with corresponding threaded fasteners mounting hole.
