Description
Technical field
The present invention relates to put discharging frame from riser.
Background technique
Currently, the pendulum discharging frame of pipe class part, which generallys use, is welded and fixed formula structure, pipe fitting circulates from transfer matic
It drops down onto material frame.Wherein, it can be generated with material frame or other part pipes when pipe fitting is fallen and hit, collide with.Pipe fitting uses this kind of life
Processing method is produced, is on the one hand easy to cause tube surface to generate mechanical damage, influences product surface quality, it is subsequent to need to increase it
Add surface polishing operation, consume manpower and material resources, is unfavorable for the workshop large scale investment manufacturing.On the other hand, with transfer matic
The increase of upper pipe fitting accumulated number causes the pipe fitting entirety center of gravity stacked in sinking tendency, and subsequent needs are artificially by pipe fitting from pendulum
Promotion, handling come out in discharging frame, influence to manufacture efficiency.
Summary of the invention
The present invention compares the prior art and has the advantages that: pipe class part circulates from transfer matic falls to one kind certainly
It is promoted on the wirerope that pipe is put in material frame, can significantly slow and be hit when pipe fitting is fallen with material frame or the generation of other part pipes
It hits, collide with, avoid tube surface and generate mechanical damage, improve product surface quality.At the same time, with transfer matic upper tube
The increase of part accumulated number is cranked arm rotation by putting dog-ear in discharging frame from riser, achievees the purpose that automatic lifting pipe fitting,
It is subsequent to be not necessarily to artificially come out pipe fitting from promotion, handling in discharging frame is put, improve production efficiency.
The advantages that apparatus of the present invention design structure is simple, manufacturing cost is low, easy to use.For the pipe class of different bores
Part has very high versatility.Therefore, apparatus of the present invention have very high practicability, workshop large scale investment easy to produce
It uses.

Specific embodiment
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the present invention is not limited to
Embodiment below.
One kind from riser put discharging frame, including pedestal 1, dog-ear crank arm 2, pin shaft 3, split pin 4, extension spring 5, resistance
Buddhist nun's wire wrapping disk 6, idler wheel 7, wirerope 8 are constituted.
Pedestal 1 is set as weldment, in the present embodiment, the pedestal 1 by 1 piece of upper plate 1-1,1 piece of lower plate 1-2 and in
Between at position 2 pieces of side plate 1-3 be welded.Inside the pedestal 1,2 pieces of platform sling 1-5 are equipped on upper plate 1-1, between part
It is set as being welded to connect.
Dog-ear, which is cranked arm, 2 is set as weldment, and in the present embodiment, the dog-ear, which is cranked arm, 2 is equipped with 1 piece of lifting lug 2-3, between part
It is set as being welded to connect.
Dog-ear, which is cranked arm, 2 to be mounted on pedestal 1, is attached by pin shaft 3, split pin 4.The idler wheel 7 is mounted on dog-ear
It cranks arm on 2, is attached by pin shaft 3, split pin 4.Platform sling 1-5 in described 5 one end of extension spring connection pedestal 1, it is another
End connection dog-ear is cranked arm the lifting lug 2-3 in 2.The damping wire wrapping disk 6 is mounted on the side plate 1-3 in pedestal 1, is set between part
To be welded to connect.The wirerope 8 is set as cyclic annular, and the wirerope 8 is mounted on damping wire wrapping disk 6 and idler wheel 7.
It is described it is another put discharging frame from riser, including pedestal 1, dog-ear crank arm 2, pin shaft 3, split pin 4, stretch bullet
Spring 5, damping wire wrapping disk 6, idler wheel 7, track cable 8, pulley 9, switching wirerope 10 are constituted.
Pedestal 1 is set as weldment, in the present embodiment, the pedestal 1 by 1 piece of upper plate 1-1,1 piece of lower plate 1-2 and in
Between at position 2 pieces of side plate 1-3 be welded.Inside the pedestal 1,2 pieces of platform sling 1-5 are equipped on upper plate 1-1, between part
It is set as being welded to connect.
Dog-ear, which is cranked arm, 2 to be mounted on pedestal 1, is attached by pin shaft 3, split pin 4.The idler wheel 7 is mounted on dog-ear
It cranks arm on 2, is attached by pin shaft 3, split pin 4.The extension spring 5 connects dog-ear and cranks arm 2.The damping wire wrapping disk 6
It is mounted on the side plate 1-3 in pedestal 1, is set as being welded to connect between part.The 8 both ends end of track cable connects pulley
9, the switching wirerope 10 is mounted on damping wire wrapping disk 6, on idler wheel 7, and passes through pulley 9, cranks arm and 2 is connected with dog-ear
It connects.
Wirerope 8 is mounted on damping wire wrapping disk 6 and idler wheel 7.The generation of sagging or shape is generated when wirerope 8 bears load
When change, idler wheel 7 can be driven to generate rotation, to reduce frictional resistance.It is characterized in that, working as positive/negative damping due to rotation wire wrapping disk 6
When, it can increase/reduce the perimeter length of (control) wirerope 8.It can be by being set to damping wire wrapping disk 6:
The first situation are as follows: when wirerope 8 bears load, damping wire wrapping disk 6 does not change the length of wirerope 8, only rises
It is acted on to damping transmission.
Second situation are as follows: when wirerope 8, which bears load, to be increased, damp the effect dampened of wire wrapping disk 6, slow release steel
Cord 8 realizes the function that 8 length of wirerope is slowly increased.When wirerope 8, which bears load, to be reduced, damping wire wrapping disk 6 is dampened
Wirerope 8 is slowly tightened in effect, realizes the function that 8 length of wirerope slowly reduces.
One kind is as follows using operating procedure from riser pendulum discharging frame:
1, zero (group) part in device is assorted, the welding equipment operation of material frame is completed.
2, pipe fitting by root from transfer matic circulation fall to from riser pendulum discharging frame in wirerope on, wirerope because
It bears load and generates sagging (becoming sagging from exceptionally straight state), as the pipe fitting accumulated number on transfer matic increases, from riser
Son pendulum discharging frame in dog-ear crank arm and (inside) will be rotated inwards, and between pedestal horizontal line be in included angle by
It is cumulative big, with the layer-by-layer pile of pipe, it is ensured that pipe falls code in higher position always, reduces pipe tenesmus drop, reaches
The purpose of automatic lifting pipe fitting.Discharging frame is put by using from riser, so that pipe fitting is in a high position always and lifts state, is reduced
Pipe whereabouts impact noise.Wherein, when dog-ear is cranked arm generation rotation, cranking arm the extension spring of connection with dog-ear then will be gradually
Tensile elongation is never gradually become by state of tension by state of tension.Under the effect of extension spring elastic force, can crank arm to dog-ear production
Raw active force restores to the trend of original state.
3, when pipe fitting by root or all from when removing from riser pendulum discharging frame, dog-ear, which is cranked arm, to be revolved outward
Turn, and the angle between pedestal horizontal line is gradually successively decreased or revert to original state, wherein pulling force suffered by extension spring
The state of not stressing is gradually reduced or reverts to, tensile elongation is also gradually shortened or reverts to constant shape state.Wirerope is again
It is restored back to exceptionally straight state (becoming exceptionally straight from hang).
