Description
Technical field
The present invention relates to a kind of suspension type overloading and unbalanced loading of container detection means.
Background technology
Need to use twist lock in container in hoisting status operation, for four ends of container angle to be locked and then hung
Fortune, to realize detection to twist lock stress, now can on twist lock install sensor, the twist lock of conventional mounting sensor it is for example first
Patent（The patent No.：201310215502.1）Middle introduction, the installation of its resistance strain gage is mainly symmetricly set on twist lock
Both sides, its needs open up mounting hole on twist lock, can thus reduce the sectional area in the middle part of twist lock, the tension for weakening twist lock is strong
Degree, easily snap off during lifting, influence safety.Secondly, conventional this mounting means can not realize that stress is examined to the whole circumference of locking bar
Survey, blind area be present, detect unclear standard.
The content of the invention
The technical problem to be solved in the present invention is：Overcome the deficiencies in the prior art, there is provided a kind of suspension type container is super inclined
Detection means is carried, solves the defects of conventional twist lock detection is not accurate.
The technical solution adopted for the present invention to solve the technical problems is：A kind of suspension type overloading and unbalanced loading of container detection dress
Put, including locking bar, described locking bar one end are provided with the tapered end for coordinating with container, the locking bar other end is provided with screw thread
Form connection end；
Force-measuring section is formed in the middle part of the locking bar, the outer ring of the force-measuring section is provided with resistance strain gage, and the resistance strain gage is being locked
Winding is annularly fitted on the force-measuring section of locking bar on bar；
The connection end of the locking bar axially offers axial threading hole, and the locking bar force-measuring section offers radial direction threading hole, described
Axial threading hole is inner to be connected with radial direction threading hole the inner, and wire should with resistance after passing through radial direction threading hole and axial threading hole
Become piece connection.
Further, the force-measuring section upper and lower ends form lead-over groove on locking bar respectively.
The beneficial effects of the invention are as follows：In the locking bar that this practicality detection means uses, by resistance strain gage on locking bar
Cyclic structure is designed to, therefore can be realized to locking bar force-measuring section circumference complete detection, lifting detection precision.And avoid
Mounting hole is opened up on locking bar, lifts twist lock tensile strength.
The design of lead-over groove can avoid other parts on locking bar from influenceing the accurate detection of force-measuring section because material is uneven.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the schematic diagram of detection means of the present invention；
Wherein, 1, locking bar, 2, tapered end, 3, force-measuring section, 4, resistance strain gage, 5, lead-over groove.
Embodiment
Presently in connection with accompanying drawing, the present invention is further illustrated.These accompanying drawings are simplified schematic diagram only with signal side
Formula illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
As shown in figure 1, a kind of suspension type overloading and unbalanced loading of container detection means, including locking bar 1, the one end of locking bar 1 are provided with use
In the tapered end 2 coordinated with container, the other end of locking bar 1 is provided with screw thread and forms connection end；Tapered end 2 is used to connect between container
Connect, connection end is used to be connected with the suspender of gantry crane.
The middle part of locking bar 1 forms force-measuring section 3, and the outer ring of force-measuring section 3 is provided with resistance strain gage 4, and the resistance strain gage 4 is being locked
Winding is annularly fitted on the force-measuring section 3 of locking bar 1 on bar 1.The section of force-measuring section 3 is circle, and resistance strain gage 4 is directly bonded
On the outer wall of force-measuring section 3.
The connection end of locking bar 1 axially offers axial threading hole, and the force-measuring section 3 of locking bar 1 offers radial direction threading hole, axially worn
String holes it is inner with radial direction threading hole is inner connects, wire pass through after radial direction threading hole and axial threading hole with resistance strain gage 4
Connection.
The upper and lower ends of force-measuring section 3 form lead-over groove 5 on locking bar 1 respectively.The design of lead-over groove 5 can be avoided on locking bar 1
Other parts influence the accurate detection of force-measuring section 3 because material is uneven.
The detection means of the present invention, resistance strain gage 4 are directly fitted in the outer wall of locking bar 1, avoid the perforate on locking bar 1, carry
The tensile strength of locking bar 1 is risen, resistance strain gage 4 is annularly set, and realizes the circumferential complete detection to locking bar 1, lifting detection essence
Accuracy.
It is complete by above-mentioned description, relevant staff using the above-mentioned desirable embodiment according to the present invention as enlightenment
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
