Summary of the invention:
Object of the present invention be exactly to provide a kind of compact conformation rationally, stable performance, self-locking strand pulling machine easy to use, flexible for installation.
The object of the present invention is achieved like this, a kind of self-locking strand pulling machine, comprise casing, gear, rocker, frame, it is characterized in that: above described frame, be provided with casing, frame left end is hinged is connected with installing plate, casing arranged outside has the adjusting screw(rod) fixing with installing plate, installing plate is provided with multispeed electric machine, multispeed electric machine is provided with minor sprocket; Casing is provided with sprocket shaft, bridge shaft and three rocker lower shafts; Described sprocket shaft is provided with hinge wheel and travelling gear; Described bridge shaft is provided with carrier gear; Carrier gear, travelling gear are arranged on box house and are meshed with two gears; Be provided with lashing wheel and gear in the middle of described three rocker lower shafts, lashing wheel and gear both sides are provided with rocker; Often organize on rocker and be provided with axle on rocker, rocker axle is provided with lashing wheel and gear, the gear on same group of rocker on rocker on axle and rocker lower shaft engages each other; Being connected into by connecting plate between rocker and rocker can the interlock body of synchronous hunting; Connecting plate is provided with handle, and connecting plate enters Shu Duan and is provided with clamping screw.
Frame of the present invention is provided with installing hole.
Compact conformation of the present invention rationally, stable performance, easy to use, flexible for installation.
Accompanying drawing illustrates:
Fig. 1 is the front view in structural representation of the present invention.
Fig. 2 is the top view in structural representation of the present invention.
Fig. 3 is transmission principle figure in the present invention.
In figure 1, enter to restraint mouth, 2, casing, 3, clamping screw, 4, rocker 5, handle, 6, gear, 7, lashing wheel, 8, axle, 9 on rocker, rocker lower shaft, 10, goes out to restraint mouth, 11, frame, 12, installing hole, 13, sprocket shaft, 14, bridge shaft, 15, adjusting screw(rod), 16, hinge, 17, installing plate, 18, multispeed electric machine, 19, hinge wheel, 20, connecting plate, 21, minor sprocket, 22, travelling gear, 23, carrier gear.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the invention will be further described:
With reference to accompanying drawing, a kind of self-locking strand pulling machine, comprise casing 2, gear 6, rocker 4, frame 11, it is characterized in that: described frame 11 is provided with casing 2 above, frame 11 left end is hinged is connected with installing plate 17, casing 2 arranged outside has the adjusting screw(rod) 15 fixing with installing plate 17, installing plate 17 is provided with multispeed electric machine 18, multispeed electric machine 18 is provided with minor sprocket 21; Casing 2 is provided with sprocket shaft 13, bridge shaft 14 and three rocker lower shafts 9; Described sprocket shaft 13 is provided with hinge wheel 19 and travelling gear 22; Described bridge shaft 14 is provided with carrier gear 23; Carrier gear 23, travelling gear 22 are arranged on casing 2 inside and are meshed with two gears 6; Be provided with lashing wheel 7 and gear 6 in the middle of described three rocker lower shafts 9, lashing wheel 7 and gear 6 both sides are provided with rocker 4; Often organize on rocker 4 and be provided with axle 8 on rocker, axle 8 is provided with rocker lashing wheel 7 and gear 6, on same group of rocker 4, on rocker, axle 8 engages each other with the gear 6 on rocker lower shaft 9; Being connected into by connecting plate 20 between rocker and rocker can the interlock body of synchronous hunting; Connecting plate 20 is provided with handle 5, connecting plate 20 enters Shu Duan and is provided with clamping screw 3.Described frame 11 is provided with installing hole 12.During concrete enforcement, on multispeed electric machine, minor sprocket drives hinge wheel on sprocket shaft to rotate, cog 22 gears 6 in the middle of drives and the right gear 6 of sprocket shaft rotates, middle gear 6 drives carrier gear 23 to rotate, carrier gear drives left side gear 6 to rotate, and the gear 6 of lower row drives the upper gear 6 arranged and the lashing of arranging up and down wheel to rotate.When wearing steel bunch, lashing is taken turns and is arranged on directly over lower lashing wheel, now be convenient to steel bunch, steel bunch is by taking turns by about three groups lashings the steel bunch passage formed, then clamping screw is adjusted, make interlock body swing upper lashing wheel to swing around lower lashing wheel, thus compacted to steel bunch steel bunch of exerting pressure.Drive upper and lower lashing to take turns reverse sync respectively by the power transmission on gear after start to rotate, steel bunch is travelled forward.The linear velocity of steel bunch is faster, and upper lashing wheel is larger to the power of steel bunch effect, and self-lock force is also larger, and being the interactively formed under dynamic action under self-locking locking state between them, is self-locking state disappearance as dynamically terminated.When steel bunch needs to retreat, can exit from strand pulling machine by exiting button steel bunch.When steel bunch worn again by needs, clamping screw is retreated, pull handle and the interlock body of swing is resetted so that threading.The present invention is arranged on scaffold by pipe by installing hole that frame is arranged as required, and transfer rate of the present invention can regulate as required, easy to operate, stable performance.
