Detection device by artificial regular visit or is directly to connect bolt end to end by wirerope using German import detector
Both ends, bolt looseness will pull wirerope and then be broken triggering alarm, both modes can meet certain detection and want
It asks, but also all haves the defects that certain, artificial regular visit can only observe by the naked eye micro-judgment, the big detection accuracy of error
It is low, it is possible that being not detected but having generated loosening, column foot use is influenced, security risk is big, manual inspection labor intensity
Greatly, high labor cost, and use German detector that professional is needed to install, the big installation cost of installation difficulty is high, and is primary
Property just broken using rear wirerope, use cost is high, needs to frequently replace wirerope, and it is inconvenient to replace trouble.
The technical problem to be solved by the present invention is to provide one kind without manual inspection, the high error of detection accuracy is small, no
Influence column foot is small using security risk, installation is simply not required to professional, can detect use for a long time, use cost is low, without frequency
Numerous replacement operation more easily construction hoisting machinery bolt looseness automatic detection mechanism.
Utility model content
To solve, the above-mentioned big precision of prior art manual inspection error is low, it is big using security risk to influence column foot, labour is strong
Spend big high labor cost, German detector needs professional's installation, the big installation cost of installation difficulty is high, after disposable use just
The problems such as disconnected use cost is high, the frequent replacement operation of need is inconvenient, the utility model adopts the following technical solution:
The utility model provides a kind of construction hoisting machinery bolt looseness automatic detecting structure, including bolt, several spiral shells
Female and loosening testing agency, the bolt, which is worn, to be fastened on column foot standard knot, several described nut threads are locked at bolt
On the screw thread of upper end, the loosening testing agency is fastened on nut and including cabinet, upper cover, wirerope, wirerope locking screw
Nail, back-moving spring, induction sliding piece and detection display circuit, the upper cover fastening are fastened on cabinet, the wirerope locking
Screw is arranged on the installation base of cabinet side and bottom offers wirerope perforation, the back-moving spring, induction sliding piece
It being separately positioned in cabinet, back-moving spring one end system hangs on the bracket of cabinet, other end system hangs on induction sliding piece,
Described wirerope one end passes through wirerope and perforate and pass through that wirerope lock-screw is locked, the other end extends be wrapped in two forward
Nut junction and end system hang on induction sliding piece, and the detection display circuit is set in cabinet and non-with sliding piece is incuded
It connects.
As the improvement to the utility model, the detection display circuit includes power supply and two displays being connected in parallel point
Circuit, described two display parallel circuits share a power supply power supply and including induction contact-making switch and display light bulb, the inductions
Contact-making switch, display light bulb, power supply three string, connection connection, the induction contact-making switch and the induction non-contact connection of sliding piece.
The utility model has the beneficial effects that: spring and induction sliding piece disequilibrium, sense when bolt loosens
Answering sliding piece swing to contact with induction contact-making switch lights its closure light bulb, and in this way can be quick and easy detect loosens simultaneously
It was found that taking measures, the high error of detection accuracy is small, and security risk is small, small artificial at low cost without manual inspection labor intensity, peace
It fills simple to operate, use can be detected for a long time, use cost is low, uses without frequently replacement more convenient.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model.
Fig. 2 is the partial enlargement diagram of induction sliding piece and detection display circuit in the utility model.
Specific embodiment
The preferred embodiment that according to the present invention will be described in detail below with reference to the accompanying drawings.
Referring to Fig. 1, a kind of construction hoisting machinery bolt looseness automatic detecting structure, including bolt 1, several nuts 2
With loosening testing agency 3, the bolt 1, which is worn, to be fastened on column foot standard knot, several described 2 screw-threaded couplings of nut are in bolt
On 1 upper end screw thread, the loosening testing agency 3 is fastened on nut 2 and including cabinet 31, upper cover 32, wirerope 33, steel wire
Lock-screw 34, back-moving spring 35, induction sliding piece 36 and detection display circuit 37, the upper cover 32 of restricting fasten and are fastened on cabinet
On 31, dustproof and waterproof can be played the role of, guarantee the stability of detection, the wirerope lock-screw 34 is arranged in cabinet 31 1
On the installation base 38 of side and bottom offers wirerope perforation, and the back-moving spring 35, induction sliding piece 36 are separately positioned on
In cabinet 31,35 one end system of back-moving spring is hung on the bracket of cabinet 31, other end system hangs on induction sliding piece 36, institute
33 one end of wirerope is stated perforate across wirerope and pass through that wirerope lock-screw 34 is locked, the other end extends be wrapped in two forward
A 2 junction of nut and end system hang on induction sliding piece 36, and when bolt loosening does not occur, back-moving spring, induction are stirred
It is motionless that piece is to maintain relative equilibrium, referring to Fig. 2, wherein, the detection display electricity, 37 include that power supply and two are connected in parallel
Display parallel circuit, described two display parallel circuits share a power supply power supply and including induction contact-making switch and display light bulb,
The induction contact-making switch, display light bulb, power supply three string, connection connection, the induction contact-making switch with incude that sliding piece is non-connects
