Description

Auto-locking suspension hook apparatus
Technical field
The present invention relates to a kind of suspension hook, specifically a kind ofly be used for the auto-locking suspension hook apparatus that the landing impact testing machine tup is mentioned and discharged.
Background technology
We know that an important process in the landing impact testing machine design is exactly the suspension hook part in the elevator system.At present, the hook gear that external landing impact testing machine adopts does not have auto-lock function, and poor reliability; Domestic a kind of old-fashioned hook gear picks up suspension hook by electromagnet, needs manually hook, complex operation.
Summary of the invention
Technical matters to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, and operation, easy to use, safe and reliable has the auto-locking suspension hook apparatus of automatic coupling.
The technical scheme that the present invention solves the problems of the technologies described above employing is, a kind of auto-locking suspension hook apparatus, it comprises support frame, suspension hook, securing rod, it is characterized in that: symmetrically arranged a pair of open-close type suspension hook is installed on the support frame by rotating shaft, suspension hook top is provided with the shoulder of laying lock core, being provided with an extension spring between the shoulder on two suspension hook tops links to each other, the suspension hook bottom is provided with the hook of lateral bending song inwards, the hook lower surface is the inclined-plane, the bottom of the inboard shoulder correspondence of suspension hook is provided with the boss that contacts with suspension ring, securing rod is movably arranged on the support frame by support, and the one end is connected with support by bearing pin, and the other end is connected with electromagnet core by bearing pin, rise and fall by magnet control, be provided with the lock core of downward protrusion in the middle of the securing rod, lock core cooperates with the shoulder on suspension hook top, falls within on the open shoulder of suspension hook, closed and the auto lock of two suspension hooks, lock core shifts out from the suspension hook shoulder, and outwards open the suspension hook bottom, and the object of slinging falls.
The present invention is provided with a pair of open-close type suspension hook, closure by securing rod control suspension hook, against existing technologies, it is without additionaling power, deadweight by landing impact testing machine crossbeam and securing rod is a locking power fully, lock core inserts on the shoulder of suspension hook, and hook gear is in self-locking state, can promote tup; When discharging tup, the electromagnetic actuation securing rod, lock core sucking-off from the suspension hook shoulder, suspension hook outwards opens, and tup falls.The present invention is simple in structure, operation, easy to use, safe and reliable, and lifting, release tup can be realized control automatically, suspension hook has auto-lock function, the safe coefficient height.
Description of drawings
The present invention is further described below in conjunction with accompanying drawing.

Embodiment
From Fig. 1, Fig. 2, Fig. 3, Fig. 4 as can be seen, a kind of auto-locking suspension hook apparatus, it comprises a pair of open-close type suspension hook that support frame 1, left suspension hook 5 and right suspension hook 4 form, securing rod 2 etc.Support frame 1 is the pith in the landing impact testing machine elevator system, is used to support whole suspension hook, and securing rod 2 is used for making the locking of two suspension hooks or discharges.
The present invention is symmetrical arranged a pair of open-close type suspension hook.Wherein left suspension hook 5 is connected with support frame 1 by rotating shaft 6 with right suspension hook 4, can 6 freely rotate around the shaft.The inboard, top of left side suspension hook 5 and right suspension hook 4 is respectively equipped with shoulder 8, the shoulder 9 of laying lock core, and the bottom of the inboard shoulder 8 of suspension hook, shoulder 9 correspondences is provided with boss 10, the boss 11 that contacts with suspension ring.Suspension ring are the parts that connect tup in the landing impact testing machine elevator system.The present invention left side suspension hook 5 is provided with extension spring 7 with 4 shoulders 8,9 at an upper portion thereof of right suspension hook and links to each other.Extension spring 7 makes and has an open power between two suspension hooks all the time.Left side suspension hook 5 and right suspension hook 4 bottoms are provided with the hook of lateral bending song inwards, and the hook lower surface is the inclined-plane.
Securing rod 2 of the present invention is movably arranged on the support frame 1 by support 3.To the lock core 21 that has protrusion, securing rod 2 one ends are connected with support 3 by bearing pin in the middle of the securing rod 2, and the other end is connected with an electromagnet core by bearing pin, is risen and fallen by magnet control, can together lift or fall with iron core by the action of electromagnet.
When the present invention uses, the landing impact testing machine crossbeam descends, and the inboard boss 10,11 that contacts with suspension ring of suspension hook contacts stressed with suspension ring, and outwards rotate around the shaft on suspension hook top, by deadweight, the lock core 21 that securing rod protrudes falls within 9 of left suspension hook 5 and right suspension hook 4 open shoulders 8, shoulders.Since the effect of lock core 21, two suspension hook closures, auto lock, and can't open laterally again, thereby hook suspension ring, mention tup.As shown in Figure 3, Figure 4.
When discharging tup, electromagnetic actuation securing rod 2, lock core 21 sucking-off from the suspension hook shoulder, suspension hook outwards opens, and tup falls.As shown in Figure 1 and Figure 2, electromagnet picks up iron core, driving securing rod 2 and lock core 21 moves up, the restraint of 21 pairs of left suspension hooks 5 of lock core and right suspension hook 4 disappears, equalising torque is destroyed, and left suspension hook, right suspension hook respectively have the moment of a countershaft, under the effect of this moment, left and right sides suspension hook opens laterally, and tup is released.Left side suspension hook, right suspension hook owing to there is not the moment of resistance effect of lock core, so weight is very little to the pressure of suspension hook face, just can rotate as long as overcome the friction force of rotating shaft, so the wearing and tearing of suspension hook are very little in the process that rotation discharges.
