Description
Technical field
It the utility model is related to construction equipment technical field, more particularly to a kind of stacker crane body standard knot height
Strength bolts loosen detection means.
Background technology
Stacker crane body has multiple standard knots to be formed with high strength exploitation, and all bolts must all fasten jail
Lean on, bolt is easily loosened, it is necessary to loosening has been periodically checked whether, because of connecting bolt number by alternate load effect in tower crane work
The more situations for often having missing inspection of amount, it is impossible to determine that bolt has non-loosening easily to trigger security incident, cause casualties and economic
Loss.
Utility model content
The purpose of this utility model there is provided a kind of stacker crane body standard knot high-strength bolt and loosen detection dress
Put, this is easy for installation, and bolt looseness situation can be whether there is with automatic detection crane tower-body standard section high-strength bolt, ensures follow-up
The security of construction process, avoid the generation of contingency.
To achieve these goals, the technical solution adopted in the utility model is as follows：
A kind of stacker crane body standard knot high-strength bolt loosens detection means, including crane tower body body, institute
The crane tower body body stated is provided with transition segment framework, and described transition segment framework is provided with several connectors, the mistake
Section framework is crossed by being connected above connector with crane tower top, lower section is connected with crane rotation platform, and left side is put down with crane
The arm that weighs is connected, and right side is connected with crane boom, and the transition segment framework side switchs provided with laser photoelectricity, the laser light
For electric switch by being connected from smooth vertical means with transition segment framework, the laser photoelectricity switch lower section is provided with optical reflective disk, described
Optical reflective disk is connected by connecting plate with transition segment framework.
Further, described transition segment lower portion is provided with several reinforcements.
Further, the big I of described optical reflective disk is according to regulating working conditions.
Wherein it is used to keep laser photoelectricity laser beam switching Vertical Launch all the time from smooth vertical means, during tower crane zero load,
Slewing tower has hypsokinesis angle under balance weight effect, and tower crane is born slewing tower when service load is about rated value and occurred
Forward leaning angle, above-mentioned hypsokinesis angle and forward leaning angle can all increase if tower-body standard section connecting bolt has loosening, pass through tune
The size of whole optical reflective disk, in the case of tower-body standard section all fastening so that laser beam is mapped to reflective plate edge, if tower
Body standard knot connecting bolt has loosening, then laser beam is irradiated less than optical reflective disk, and optoelectronic switch does not receive reflection laser, is got an electric shock
Action sends alarm signal and simultaneously switches off tower crane control loop.
Compared with the prior art, the beneficial effects of the utility model are as follows：
The utility model is realized to stacker crane body standard knot by parts such as laser photoelectricity switch and optical reflective disks
The loosening detection of high-strength bolt, accuracy of detection is higher, and Detection results are preferable, it is possible to prevente effectively from subsequent construction contingency
Occur, the construction of safeguard work personal security.

Embodiment
In order that technological means, creation characteristic, reached purpose and effect that utility model is realized are easy to understand, below
With reference to being specifically illustrating, the utility model is expanded on further.
As shown in figure 1, a kind of stacker crane body standard knot high-strength bolt loosens detection means, including crane tower
Body body, crane tower body body are provided with transition segment framework 3, and transition segment framework 3 is provided with several connectors 1, transition segment
Framework 3 is connected by the top of connector 1 with crane tower top, and lower section is connected with crane rotation platform, left side and crane balance
Arm is connected, and right side is connected with crane boom, and the side of transition segment framework 3 is provided with laser photoelectricity switch 6, laser photoelectricity switch 6
By being connected from smooth vertical means 7 with transition segment framework 3, the lower section of laser photoelectricity switch 6 is provided with optical reflective disk 5, and optical reflective disk 5 passes through
Connecting plate 4 is connected with transition segment framework 3, and the inside of transition segment framework 3 is provided with two reinforcements 2, and 5 big I of optical reflective disk is according to operating mode
Regulation.
The change of hypsokinesis angle and forward leaning angle when being loosened using tower-body standard section connecting bolt, to realize to high intensity spiral shell
The detection that bolt loosens, precision is higher, and Detection results are preferable, by adjusting the size of optical reflective disk 5, realizes precise positioning.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.This
The technical staff of industry is retouched in above-described embodiment and specification it should be appreciated that the utility model is not restricted to the described embodiments
That states simply illustrates principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model
Various changes and modifications are also had, these changes and improvements are both fallen within claimed the scope of the utility model.This practicality is new
Scope is claimed by appended claims and its equivalent thereof in type.
