The specific embodiment
With reference to figure 1, the agent structure of suspender (contained structure of supporting construction and INT COMP) comprises suspender body 4, arm base 19, strut bar 20 and support disk 21.Suspender body 4 is tubular, has waist hole 24 on its tube wall.Outer wall one side at suspender body 4 is fixed with arm driving handle pole 17.Arm base 19 is fixed on the lower end of suspender body 4 by modes such as welding, riveted joint, bolt connections, preferred weld, and intensity is high, and is simple to operate.Two strut bars 20 are fixed on the both sides of suspender body 4 by fixed connecting rod 18, and to downward-extension, arm base 19 are clipped in the middle.In the present embodiment, strut bar 20 is the both sides that indirectly are fixed on suspender body 4 by fixed connecting rod 18, the effect of pipe link 18 is to make between two strut bars 20 to have certain distance, make strut bar 20 can stretch in the cylinder-bore, those of ordinary skills can imagine at an easy rate, strut bar 20 can also directly be fixed on the both sides of suspender body 4 after the bending of top, but after the both sides of suspender body 4 are fixedly connected by welding bar 18, again at fixed connecting rod 18 welding strut bars 20, intensity is better, processes more convenient.On strut bar 20, be fixed with support disk 21.
With reference to figure 2, an end relative with arm base 19 on suspender body 4, hanging block 13 has realized connecting with the pin of suspender body 4 by shipping and reselling on another market, and in the lifting process, hanging block 1 pin 3 rotations that can rotate make the lifting process more steady.Certainly, shown in chain sling 2(Fig. 6) can also be directly connected on the suspender body 4.The arm driving handle is made of driving handle base 6 and handle 8.One end of driving handle base 6 has the waist hole, and the other end 7 realizes that with arm driving handle pole 17 pin connects by shipping and reselling on another market.Driving handle base 6 and handle 8 weld togethers.Certainly, driving handle base 6 also can be processed into integral piece with handle 8.On arm base 19, two arms 11 are installed.Arm 11 all has the waist hole at 10 places that ship and resell on another market, and arm 11 can rotate to open or close around rotating shaft 9.
With reference to figure 3, shown in engine cylinder-body 23(Fig. 6) landing from the arm 11, preferably have groove 16 at arm 11.
With reference to figure 4, it has been shown in further detail the mounting structure of arm 11.Two arm 11 alternative arrangement, and 9 be installed on the arm base 19 by shipping and reselling on another market, keep intervals by cushion block 22.The force side of arm 11 10 links together by shipping and reselling on another market, and is connected (in view, arm push rod 12 is invisible at N) with arm push rod 12.
With reference to figure 5, it illustrates in greater detail the INT COMP of suspender body 4 and the connection structure of arm push rod 12 and other parts.Arm push rod 12 is positioned at suspender body 4 inside, with suspender body 4 bearing fits, and by orienting lug 5 maintenance directions.Preferably exist lock screw 13 to pass suspender body 4, rotational lock screw 13 can be locked arm push rod 12, and then the motion of restriction arm push rod 12, makes that push rod 12 keeps motionless in the suspender lifting process, guarantees the safety of lifting.Set pin 26 passes waist hole 24 and arm push rod 12, cooperates with waist hole on the driving handle base 6, therefore, when clutching handle 8, driving handle base 6 pin 7 rotation that rotates promotes set pin 26 24 interior downward motions in the waist hole, correspondingly, arm push rod 12 also moves downward.Because the lower end of arm push rod 12 10 is sold with the force side of arm 11 and to be connected by shipping and reselling on another market, so arm 11 is opened under the promotion of arm push rod 12.In the outside of arm push rod 12, be set with pull back spring 15, pull back spring 15 1 ends are against on the orienting lug 5, and an end is against on the set pin 14 on the arm push rod.When arm push rod 12 moved downward, pull back spring 15 was compressed, and when release handle 8, pull back spring 15 makes arm push rod 12 upward movements under the effect of restoring force.In the present embodiment, pull back spring 15 is stage clip, and those of ordinary skills can imagine that pull back spring 15 can be arranged on the form of extension spring between the upper end and set pin 14 of suspender body 4 equally.
In conjunction with Fig. 6 and Fig. 8.When engine cylinder-body 23 is lain on one's side, clutch handle 8, arm 11 is opened, strut bar 20 and support disk 21 are stretched in the cylinder-bore, support disk prop up cylinder bore wall or and cylinder wall between have less gap.Release handle 8, under the effect of pull back spring 15, arm 11 is closed, and clamps the dead slot on the crankshaft hole of engine cylinder-body.Tighten lock screw 13, make arm 11 remain on clamped condition.Pulling chain sling 2, under Action of Gravity Field, along with the carrying out of lifting, engine cylinder-body 23 overturns 90 ° gradually.In the lifting process, 23 guiding of 21 pairs of engine cylinder-bodies of strut bar 20 and support disk and supporting role can not collided with suspender engine cylinder-body 23.
With reference to figure 7, for fear of the interference between arm 11 and the support disk 21, the center-biased of the relative strut bar 20 of center of circle C1 of support disk 21 is for arm 11 provides larger activity space.
