Technical field
The utility model relates to a kind of locking device, particularly a kind of hydraulic rotary locking device that is used for down-the-hole arc door.
Background technology
At present; Hydraulic press pressurize self-locking is more a kind of lock ingot shape of the current use of down-the-hole arc door formula; But the risk that exists hydraulic press to break down in this way to cause gate to glide; And the long-term pressurize of hydraulic press will make hydraulic press be in the high pressure fatigue state, shorten the application life of hydraulic press greatly, so prior art is still perfect inadequately.
The utility model content
The purpose of the utility model is: a kind of simple in structure, safe and reliable, easy installation and removal is provided, behind gate lock ingot; But all pressure releases of the hydraulic press of operation gate and locking device; Security reliability is high and can prolong hydraulic press a kind of hydraulic rotary locking device that is used for down-the-hole arc door in application life, to overcome the deficiency of prior art.
The utility model is to be constructed as follows: a kind of hydraulic rotary locking device that is used for down-the-hole arc door; Be included in the free bearing and the single cylinder swing type hydraulic machine that are provided with on the inspection platform; It is characterized in that: down-the-hole arc door is provided with shackle plate and gate lifting eye; The hanging axis that is provided with on shackle plate and the pull bar is connected; Be provided with the hanger hole at the middle part of pull bar, the head that hangs of hanger hole and twin-tub suspension type hydraulic press is connected through bearing pin, and the free bearing that is provided with on pull bar and twin-tub suspension type hydraulic press and the inspection platform is connected.
Pull bar is welded to form by 2 blocks of frange plates, 2 stiffeners, 1 block of web and 4 shaft bearing plates.
On down-the-hole arc door, be symmetrically arranged with two shackle plates and two gate lifting eyes with the lock centerline hole.
Owing to adopted technique scheme; During lock ingot down-the-hole arc door; Down-the-hole arc door drives the lower edge camber line at single cylinder swing type hydraulic machine and moves upward; When shackle plate with after the pull bar hanging axis contacts then move downward, pull bar drives the inboard border line of lower edge shackle plate at twin-tub suspension type hydraulic press and makes relative motion to hanging axis and embed the hanger hole fully simultaneously; When withdrawing from the lock ingot; Down-the-hole arc door drives the lower edge camber line at single cylinder swing type hydraulic machine and moves upward; Simultaneously pull bar is after twin-tub suspension type hydraulic press drives the inboard border line of lower edge shackle plate and makes relative motion to hanging axis and break away from the hanger hole fully, and down-the-hole arc door is along camber line then move downward and can remove the lock ingot; Compared with prior art; The utility model not only has simple in structure; Safe and reliable advantage; And behind down-the-hole arc door lock ingot, but all pressure releases of hydraulic press of operation gate and locking device have and prevent to cause when hydraulic press from breaking down the sliding advantages such as application life that have an accident and prolong hydraulic press of the down-the-hole arc student.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
The enforcement of the utility model: a kind of hydraulic rotary locking device that is used for down-the-hole arc door; Be included in the free bearing 9 and single cylinder swing type hydraulic machine 10 that are provided with on the inspection platform 15; Down-the-hole arc door is provided with shackle plate 1 and gate lifting eye 2; The hanging axis 4 that is provided with on shackle plate 1 and the pull bar 3 is connected; Be provided with hanger hole 5 at the middle part of pull bar 3, hanging of hanger hole 5 and twin-tub suspension type hydraulic press 67 is connected through bearing pin 8, and the free bearing 9 that is provided with on pull bar 3 and twin-tub suspension type hydraulic press 6 and the inspection platform 15 is connected.
Pull bar 3 is welded to form by 12,1 block of web 13 of 11,2 stiffeners of 2 blocks of frange plates and 4 shaft bearing plates 14.
On down-the-hole arc door, be symmetrically arranged with two shackle plates 1 and two gate lifting eyes 2 with the lock centerline hole, shackle plate 1 internal diameter equates with pull bar 3 hanging axises 4 external diameters and shackle plate 1 physical dimension is slightly less than pull bar 3 frange plates 11 inner dimensions;
The hydraulic press that twin-tub suspension type hydraulic press 6 and single cylinder swing type hydraulic machine 10 all are on the existing market to be sold.
During the utility model lock ingot down-the-hole arc door 16; Down-the-hole arc door 16 moves upward at single cylinder swing type hydraulic machine 10 driving lower edge camber lines; When shackle plate 1 with after the hanging axis 4 of pull bar 3 contacts then move downward, pull bar 3 is made relative motion to hanging axis 4 at twin-tub suspension type hydraulic press 6 driving lower edge shackle plates 1 inboard border line and is embedded the hanger hole fully simultaneously; When withdrawing from the lock ingot; Down-the-hole arc door 16 moves upward at single cylinder swing type hydraulic machine 10 driving lower edge camber lines; Simultaneously pull bar 3 is after twin-tub suspension type hydraulic press 6 driving lower edge shackle plates 1 inboard border line is made relative motion to hanging axis 4 and broken away from the hanger hole fully, and down-the-hole arc door 16 is along camber line then move downward and can remove the lock ingot.
