Description
Technical field
The utility model relates to a kind of overhead traveling crane suspension hook closing appliance.
Background technology
Use C type suspension hook to carry out handling, general modfel is on the overhead traveling crane suspension hook, to hang up suspension ring to carry out handling work.Because C type suspension hook will ceaselessly pass through the material volume in the course of the work, make overhead traveling crane suspension hook C type hook amplitude of fluctuation when bridging increase, so just be easy to cause the unhook situation, cause very big threat for surface work personnel's safety.For this reason, a closing appliance being set on suspension hook, is necessary in case hang thing unhook phenomenon.And existing closing appliance is because its deficiency aspect design and quality, and how long use will not be out of shape, and this situation appears in even fracture failure especially in the course of the work, directly has influence on ground staff's life security especially.Therefore, be necessary to design a kind of rational closing appliance, to adapt to numerous and diverse handling work.
Summary of the invention
In order to overcome above-mentioned deficiency; The utility model provides a kind of overhead traveling crane suspension hook closing appliance, and this device is durable in use and cost is low, has solved the various hidden dangers of bringing because of locking is insecure; Got rid of the danger of breaking off relations effectively up hill and dale, for safety and production has been brought guarantee.
The utility model adopts following technical scheme:
A kind of overhead traveling crane suspension hook closing appliance; It is characterized in that: comprise steel bushing, locking frame; Said steel bushing is located at neck of hook, and steel bushing is formed with bolt by two block plates, and the suspension hook both sides are respectively equipped with the L shaped steel plate of two parallel placements; End of two blocks of L shaped steel plates and corner part bolt together respectively are formed as one the locking frame, and the locking frame is fixed on an end and the reversal of the natural order of things of steel bushing on main hook part.
This Design of device is at first got material according to the size of suspension hook according to lever principle, fixes two steel plates with before and after the bolt at the neck of gib head earlier; And in preceding bolt the fixed latch frame; Hang and lift A end time locking C place when getting material and open automatically, put into suspender, C blocks outlet in the place when A falls back; Suspension ring can't be deviate from automatically, reached the purpose of locking.
The beneficial effect that the utility model produces: the innovative principle of (1) this patent is to utilize lever principle, and is simple to operate, and high safety is got rid of the danger of breaking off relations, effectively up hill and dale for safety and production has been brought guarantee; (2) the various situations that locking breaks, is out of shape have successfully been solved; (3) this device is made simply, and cost is low, and value of service is big, is suitable for widespread use.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Description of drawings
Fig. 1 is the structural representation of the utility model closing appliance.
Among the figure: 1 is steel bushing, and 2 is bolt, and 3 are the locking frame, and 4 is L shaped steel plate, and 5,6 is bolt, and 7 is suspension hook, and 8,9,10 represent A, B, C.
The specific embodiment
Embodiment 1: as shown in Figure 1; A kind of overhead traveling crane suspension hook closing appliance comprises steel bushing 1, locking frame 3, and said steel bushing 1 is located at suspension hook 7 necks; Steel bushing 1 is fixedly formed with bolt 2 by two block plates; End and corner part that suspension hook 7 both sides are respectively equipped with 4, two blocks of L shaped steel plates 4 of L shaped steel plate of two parallel placements connect as one with bolt 5,6 respectively and form locking frame 3, and locking frame 3 is fixed on an end and the reversal of the natural order of things of steel bushing 1 on suspension hook 7.
Concrete manufacturing process is following: (1) makes a steel bushing of being made up of the steel plate of two wide 50mm of thick 8mm according to the radian of neck of hook with size and fixes with bolt; (2) again according to two heterotype steel plate of sized (L shaped steel plate) of the opening degree and the suspension hook height of suspension hook, A, B two ends link to each other and sealing with bolt respectively.Be fixed on the B of projection end one end of steel bushing at last.Hang and lift A end time locking C place when getting material and open automatically, put into suspender.C blocks outlet in the place when A falls back, and suspension ring can't be deviate from automatically, has reached the purpose of locking.
