Description
Technical field
The utility model relate to a kind of with steel, produce help volume equipment, particularly a kind of four-bar linkage drive unit, is applicable to vertical rolling-assisting device.
Background technology
Modern cold continuous rolling band steel exports maximum speed has reached 35～40m/s.In order to improve rolling rate, shorten overhead time, the coiling machine coil in tandem mills does not all adopt jaw, and adopts rolling-assisting device will be with coil of strip on reel.Therefore, wrapper is one of visual plant during steel rolling is produced.
Coiling machine is the visual plant on output strip line, is widely used in band production.Rolling-assisting device is divided into horizontal rolling-assisting device and vertical rolling-assisting device.Horizontal rolling-assisting device is generally an autonomous device and is arranged on terrace.Vertical rolling-assisting device is arranged on coiling machine conventionally, and during work, body equipment is held reel work tightly, and under off working state, body need depart from coiling machine, swings to aerial.
Along with the continuous adjustment of present stage steel industry structure, taking-up equipment is just towards the future development of high-speed, hightension, high automation degree.Therefore the body of vertical rolling-assisting device under off working state is in aerial state, and its security becomes the hidden danger of production operation.
Traditional release mechanism is safety pin, and body and fixed mechanism that safety pin swings rolling-assisting device are solidified as a whole, and this kind of mode needs manual operation, during only as maintenance, uses.If each exiting of rolling-assisting device all needs safety pin work just safety pin need to be increased to driving mechanism in producing, driving mechanism generally all needs energy medium that power is provided.If in producing normal, rolling-assisting device runs out of steam when exiting in process and exiting, will certainly be to equipment and the personnel hidden danger that works the mischief.
Utility model content
In order to solve the release mechanism of above-mentioned existing vertical rolling-assisting device, can not guarantee at any time the safety issue of rolling-assisting device, the utility model aims to provide a kind of four bar-link drive, guarantee that rolling-assisting device is in a safe condition under off working state, run out of steam in situation in self-locking state exiting position, guarantee the safety of producing and personnel operate, do not affect normal production and maintenance.
The utility model is achieved through the following technical solutions:
A kind of four-bar linkage drive unit, comprise rolling-assisting device body and coiling machine, rolling-assisting device body is hinged on coiling machine, it is characterized in that, also comprise connecting rod one, connecting rod two, connecting rod three and drive cylinder, the bottom-hinged of described driving cylinder is on coiling machine, drive the piston rod of cylinder hinged with one end of connecting rod two, connecting rod three respectively, the other end of connecting rod three is hinged on coiling machine, one end of the other end of connecting rod two and connecting rod one is hinged, and the other end of connecting rod one radially links fixing with the top of rolling-assisting device body with key.
Above-mentioned driving cylinder is replaceable is hydraulic cylinder.
When rolling-assisting device is in running order, drive the ventilation of cylinder rod chamber, rodless cavity exhaust, drives cylinder overcome the deadweight of coiling machine body and help volume tension force, and rolling-assisting device body helps volume work.When inoperative position, drive the exhaust of cylinder rod chamber, rodless cavity ventilation, overcoming the deadweight of rolling-assisting device body makes rolling-assisting device body in exiting position completely, quadric chain is in self-locking state, even if driving cylinder dies suddenly, the deadweight of rolling-assisting device body still makes quadric chain can not produce swing in self-locking state, in a safe condition.
Rolling-assisting device body is deactivated in a process, quadric chain has a self-locking critical localisation, rolling-assisting device body and quadric chain one are by after critical potential, even if drive cylinder not drive quadric chain also can arrive the self-locking position of quadric chain under the driving of rolling-assisting device body deadweight.
The utility model guarantees that rolling-assisting device, when exiting, has mechanism's self-locking in the situation of energy medium, guarantees the safety of production maintenance.
The utility model has the advantages that: this structure guarantees that rolling-assisting device is in a safe condition under off working state, run out of steam in situation in self-locking state exiting position, guarantee to produce and the safety of personnel's operation, do not affect normal production and maintenance.

The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment mono-
In conjunction with Fig. 1, Fig. 2, the utility model provides a kind of four driving rod drives for vertical rolling-assisting device, comprise rolling-assisting device body 2 and coiling machine 1, rolling-assisting device body 2 is hinged on coiling machine 1, also comprise connecting rod 1, connecting rod 24, connecting rod 35 and driving cylinder 6, the bottom-hinged of described driving cylinder 6 is on coiling machine, drive cylinder 6 piston rod respectively with connecting rod 24, one end of connecting rod 35 is hinged, the other end of connecting rod 35 is hinged on coiling machine 1, one end of the other end of connecting rod 24 and connecting rod 1 is hinged, the other end of connecting rod 1 radially links fixing with the top of rolling-assisting device body 2 with key.
As shown in Figure 2, drive cylinder 6 rod chamber ventilations, rodless cavity exhaust, drives cylinder 6 piston rods to retract, and drives cylinder 6 to overcome coiling machine body 2 and conducts oneself with dignity and help volume tension force, and rolling-assisting device body 2 is in running order.
As shown in Figure 3, drive cylinder 6 rod chamber exhausts, rodless cavity ventilation, drives cylinder 6 piston rods to stretch out, rolling-assisting device body 2 position of deactivating, and when connecting rod 24, connecting rod 35 are during in straight line, quadric chain is in self-locking critical potential.As shown in Figure 3, the power of F4 is produced by rolling-assisting device body G for connecting rod 24, connecting rod 35 and the stressing conditions that drives the common hinged place of cylinder, and F5 equates and the equilibrant force of direction with F4 numerical value, and F5 is produced by the bearing of connecting rod 5.If the driving force F6 that drives cylinder to produce is 0, four connecting rods are in poised state.Once F6 is greater than 0, quadric chain is to the illustrated position development of Fig. 4.
As shown in Figure 4, drive cylinder 6 rod chamber exhausts, rodless cavity ventilation, drives cylinder 6 piston rods to stretch out, and overcomes 2 deadweights of rolling-assisting device body rolling-assisting device body is exited completely, in Fig. 4 position.Fig. 4 is the force analysis under self-locking state, now cylinder stuffiness, and its piston rod stretches out entirely, and cylinder can be used as the connecting rod of rigidity at this moment, and now the power of F6 is the equilibrant force that cylinder saddle produces.Quadric chain is in self-locking state.If driving cylinder 6 to die runs out of steam, Action of Gravity Field lower link 24, connecting rod 35 cannot be by the critical localisations shown in Fig. 3, thereby form self-locking (force analysis is shown in Fig. 4), only when the directed force F 6 that drives cylinder oppositely and its value enough break in the situation of quadric chain stress balance and just can break self-locking state.Even if therefore drive cylinder 6 to die suddenly, the deadweight of rolling-assisting device body 2 still makes quadric chain can not produce swing in self-locking state, in a safe condition.
