Abstract

The utility model provides a device for detecting the twist lock state of a lifting appliance, comprising a twist lock, a twist lock sheath, a thrust bearing and a twist lock pull lug, wherein the twist lock is fixed on a base of the lifting appliance by the thrust bearing connected on the twist lock pull lug, the thrust bearing and the twist lock pull lug are connected with a twist lock rotary pull rod by a joint bearing, the twist lock rotary pull rod is connected with an oil cylinder, the twist lock rotary pull rod is reciprocally stretched so as to rotate the twist lock, the top of the twist lock is provided with a twist lock nut, a limiting frame is connected on the twist lock pull lug to limit by synchronously rotating with the twist lock in a touching manner, and the limiting frame is fixed on the base of the lifting appliance. The device has the benefits of changing original indirect detection into direct detection of the twist lock state, thereby reducing the failure hidden troubles and improving the safety factor. After the original detection limiting stopper is removed, the detection limiting stopper is added on each twist lock, and the state of each twist lock is directly shown, is fed back in real time, therefore, the device reduces the safety hidden troubles and the accident rate, and makes an extraordinary contribution to the safety in production.

Description

Suspender twist lock condition checkout gear

Technical field

The utility model relates to the condition checkout gear of a kind of suspender twist lock when the crane for hoisting freight container.

Background technology

It is topmost that people-oriented is exactly that safety is placed on first that enterprise produces, and safety in production will be paid special attention to all the year, and the potential safety hazard in the production needs the very first time to get rid of.The detection of four jiaos of twist lock open and-shut modes of suspender is accurately extremely important, and it is exactly the twist lock that leans on the suspender that freight container is connected with hoisting crane in handling, the correct safety that directly influences the freight container handling of the quality of twist lock and open and-shut mode.Twist lock is distributed in four jiaos and two group of suspender, the flexible reciprocal rotation of finishing 90 ° by hydraulic ram between two twist locks, reach the state of switching, originally detection is spacing to be arranged on the flexible beam hanger of hydraulic ram, twist lock is not directly detected but the indirect open and-shut mode that reflects twist lock, the words that oil cylinder is also worked if twist lock breaks down just detect and do not go wrong, and it is hardly imaginable to continue handling freight container consequence.

Originally on the spacing flexible beam hanger that is arranged on hydraulic ram that the suspender of buying opens and closes the lock detecting device, twist lock is not directly detected, but the indirect open and-shut mode that reflects twist lock can not detect the twist lock potential problem that breaks down, and brings the hidden danger that has an accident easily.For this reason, getting rid of this potential safety hazard for hoisting crane is the task of top priority.

Summary of the invention

For solving the problem that exists in the above-mentioned technology, the purpose of this utility model provides a kind of safer suspender twist lock condition checkout gear, helps improving safety factor, gets rid of the hidden danger that exists in producing.

For achieving the above object, the technical solution adopted in the utility model provides a kind of suspender twist lock condition checkout gear, this device includes twist lock, the twist lock sheath, thrust bearing, twist lock draws ear, wherein: described twist lock draws the thrust bearing on the ear to be fixed on the suspender basis by being connected twist lock, the described twist lock of thrust bearing draws ear to link to each other with the twist lock rotating tension bar by oscillating bearing, the twist lock rotating tension bar links to each other with telescopic oil cylinder, the back and forth flexible twist lock that rotates of twist lock rotating tension bar, twist lock lock nurse is housed at the top of twist lock, position-limited rack is connected twist lock and draws on the ear, with twist lock rotate synchronously touch spacing, spacing being fixed on the suspender basis.

Effect of the present utility model is that this device changes the script indirect detection into direct detection twist lock state, reduces potential faults, improves safety factor.

The specific embodiment

Reaching embodiment in conjunction with the accompanying drawings is illustrated the structure of suspender twist lock condition checkout gear of the present utility model.

As Fig. 1, shown in 2, suspender twist lock condition checkout gear of the present utility model, this device includes twist lock 1, twist lock sheath 2, thrust bearing 3, twist lock draws ear 4, described twist lock 1 draws the thrust bearing 3 on the ear 4 to be fixed on the suspender basis 11 by being connected twist lock, thrust bearing 3 described twist locks draw ear 4 to link to each other with twist lock rotating tension bar 5 by oscillating bearing 6, twist lock rotating tension bar 5 links to each other with telescopic oil cylinder 10, the back and forth flexible twist lock 1 that rotates of twist lock rotating tension bar 5, twist lock lock nurse 7 is housed at the top of twist lock 1, position-limited rack 8 is connected twist lock and draws on the ear 4, rotate synchronously with twist lock 1 and to touch spacingly 9, spacing 9 are fixed on the suspender basis 11.

Suspender twist lock condition checkout gear of the present utility model is achieved in that

The twist lock 1 of suspender twist lock condition checkout gear is distributed in four jiaos and two group of suspender, by the flexible reciprocal rotation of finishing 90 ° of hydraulic ram between two twist locks 1, reaches the state of the switching of twist lock.With spacing the removing of detection that originally is arranged on the suspender twist lock telescopic oil cylinder 10, it is spacing to improve installation and measuring on each twist lock 1, directly reflects the state position of each twist lock 1.Be that twist lock 1, twist lock sheath 2 are fixed on the suspender basis 11 by thrust bearing 3, twist lock draws ear 4 and twist lock 1 to be connected by axle key, twist lock draws ear 4 other ends that an oscillating bearing 6 is housed, oscillating bearing 6 is connected with twist lock shackle rod 5 by pivot pin, twist lock shackle rod 5 links to each other with telescopic oil cylinder 10, and the flexible twist lock that drives in telescopic oil cylinder 10 energising backs is done 90 ° of rotations.Position-limited rack 8 is welded on twist lock and draws on the ear 4 and to rotate touching spacing 9 synchronously with twist lock 1 and reach the purpose that detects the twist lock state, and model is that spacing 9 of D4C-1420 is bolted on the suspender basis 11 by M5.
