Abstract
The utility model relates to an alarm for the separation of a hoisting steel wire rope from pulleys. The alarm comprises a power supply, light positioning and ranging sensors, an alarm lamp, an alarm bell and a manual switch which are connected in series, wherein the light positioning and ranging sensors are arranged between two pulley block positioning rib plates; the alarm lamp, the alarm bell and the manual switch are arranged in a driving chamber; and the quantity of the light positioning and ranging sensors is identical with that of pulleys in a pulley block. Due to the adoption of the light positioning and ranging sensors as sensing trigger elements and the combination with a sound-light alarming circuit, immediate warning, alarming and observation for whether the steel wire rope is displaced to be separated from a pulley groove are realized and safety accidents caused by breakage of the steel wire rope due to long-time friction are prevented.
Description
Technical field
The utility model relates to a kind of annunciator, when especially crane steel rope in hoisting process breaks away from pulley, can send the annunciator of alerting signal.
Background technology
At present crane is used more and more widely in the engineering construction construction of China, and in work progress, steel rope is damaged fracture and the safety misadventure that produces also happens occasionally about crane.A kind of situation is wherein arranged, exactly because crane in construction or advancing, is in uneven road surface or meets with the strong wind invasion and attack; Inclination to a certain degree appears in the big arm of crane, causes the steel rope in the big armed lever head of the crane assembly pulley, deviates from the pulley groove because of degree of dip is excessive; Act directly on the assembly pulley bearing pin and work; Thereby lost the friction protection of pulley, caused steel rope to hang in burden under the situation of thing, produced rigid contact friction and cause damage with the assembly pulley bearing pin; Directly cause steel rope safety tensile strength straight line to descend, the lifting safety misadventure that generation wire cable rupture, suspended object fall.
The utility model content
For overcoming the above problems, the utility model provides a kind of lifting steel rope to break away from the pulley annunciator, but when steel rope breaks away from pulley chaufeur or the site operation personnel very first time know, in time take solution, avoid the generation of hoisting process engineering accident.
For solving above technical matters, the utility model provides following technical scheme.The lifting steel rope breaks away from the pulley annunciator and comprises power supply, light positioning distance measuring inductor, alarm lamp, emergency alarm bell and hand switch, and connection mode is series connection; Positive source links to each other with alarm lamp is anodal, and the alarm lamp negative pole links to each other with emergency alarm bell is anodal, and the emergency alarm bell negative pole links to each other with the positive pole of light positioning distance measuring inductor, and the negative pole of light positioning distance measuring inductor links to each other with hand switch, and hand switch links to each other with power cathode; Light positioning distance measuring inductor is installed between the floor of assembly pulley location, and alarm lamp and emergency alarm bell and hand switch are installed in the operator's compartment; The quantity of light positioning distance measuring inductor is identical with pulley number in the assembly pulley.
Use light positioning distance measuring inductor to trigger element as induction; In conjunction with sound light alarming circuit whether steel rope is scurried the position and deviate from the pulley groove; Carry out the caution of the very first time and report to the police and observation, prevent that steel rope from long-time friction taking place and fracture causes the generation of safety misadventure.

The specific embodiment
A kind of lifting steel rope breaks away from the pulley annunciator and comprises power supply 1, light positioning distance measuring inductor 5, alarm lamp 3, emergency alarm bell 4 and hand switch 2, and connection mode is series connection; Light positioning distance measuring inductor 5 is installed between the floor 6 of assembly pulley location, and alarm lamp 3 is installed in the operator's compartment with emergency alarm bell 4 and hand switch 5; The quantity of light positioning distance measuring inductor 5 is identical with pulley number in the assembly pulley.At first hand switch 2 is closed a floodgate during lifting; Utilize the judgement of finding range of 5 pairs of pulleys of light positioning distance measuring inductor, the 7 inner groovy degree of depth; When distance measurement value greater than safety preset value scope; Can show that then steel rope 8 has broken away from the pulley groove, 5 work of light positioning distance measuring inductor make alarm lamp 3 and emergency alarm bell 4 send alerting signal; In time crane chaufeur and site operation personnel are carried out the security warning warning; Alarm lamp 3 is installed in operator's compartment with emergency alarm bell 4 or other can obviously play the remarkable position of warning function, also can combine to be installed in the mode of operation of the camera real-time monitored steel rope of the big armed lever head of crane, provides actv. to instruct foundation to follow-up protectiveness operation.
This device is simple to operation, and can know steel rope in the very first time and whether broken away from pulley, in time takes solution, avoids engineering accident to take place.
The described specific embodiment of the utility model does not constitute the restriction to the application's scope; Every within the spirit and principle of the utility model design, any modification that one of skill in the art can make, be equal to replacement, improvement etc. and all should be included within the protection domain of the utility model.
