Not enough main the performance as follows that traditional single design of restricting exists:
1, owing to adopts the simply connected reel; One section of wire rope is fixed with reel, and another section directly links to each other with gate lifting eye, for medium-and-large-sized fixation winding headstock gear (Q>500kN; Annotate: Q is the gate capacity that opens of each suspension centre of headstock gear); Wirerope diameter, drum diameter are bigger, and it is big to take the machine room space, and cost is high.
2, in the gate opening/closing process, wire rope and gate lifting eye bearing change direction with the change that opens and closes height, are prone to cause stress raisers, are prone to take place the accident of wire cable rupture.
Cable-stayed type is designed to reduce wire rope, drum diameter; Double crosslinking drum is adopted in design; Increased running block; Not enough below main the existence: the headstock gear wire rope can not fully and panel is close to, wire rope is easy be caused shake by water impact, and wire rope grazing grooving can take place, in addition job-hop, random groove phenomenon.
Summary of the invention
The headstock gear wirerope diameter, the drum diameter that The present invention be directed to existing single rope design are big; The headstock gear wire rope of cable-stayed type design can not be close to technical problems such as easy generation shake fully with panel; Provide a kind of simple in structure, it is little to take the machine room space, in light weight; Arrange compactness, compliance, the medium-and-large-sized table hole arc door fixation winding headstock gear that safety measure is good.
Technical scheme of the present invention is: a kind of medium-and-large-sized table hole arc door fixation winding headstock gear; It comprises frame, power set, deceleration device and transmission device; At least one duplex or many double crosslinking drums are housed on frame; Each duplex configuration set steel cable, wire rope are walked around each duplex group two ends that two ends behind the pulley that is arranged on the suspender are separately fixed at duplex or many double crosslinking drums.Can select the number of reel duplex group according to the headstock gear capacity; Can select the winding number of plies of reel according to the headstock gear lift.
Said frame is symmetrical 2, is separately installed with deceleration device on 2 frames, and two reduction unit output shafts link to each other with jackshaft through shaft coupling.These mechanism's power set are bilateral driving, are used for two suspension centres and open and close; Remove shaft coupling and jackshaft, about all can be used as the medium-and-large-sized table of single suspension centre hole arc door rolling open and close machine and use.
Described deceleration device can adopt the large speed ratio reducer, also can adopt little speed ratio speed reducer to add one-level exposed gear deceleration device.
Described transmission device comprises the pinion that links to each other with deceleration device and the gear wheel hinged with double crosslinking drum, and large and small gear is meshed.
Describedly be provided with position sensor at gear wheel axle head or pinion axle head; On the Large Gear Shaft During bearing, be provided with pressure sensor.
The invention has the beneficial effects as follows: the reel that is provided with on the frame is duplex or many double crosslinking drums, and each duplex group correspondence is provided with 1 wire rope, after wire rope is walked around the pulley that is provided with on the suspender; Two ends are separately fixed at the both sides of each duplex group, and suspender directly is connected with arc gantry crane ear, has effectively reduced wirerope diameter and drum diameter; Solved that traditional medium-and-large-sized table hole arc door fixation winding headstock gear wire rope, drum diameter are big, wire rope is prone to by shortcomings such as water impact poor stability, the headstock gear wire rope that has solved single rope design directly is connected the problem of the wire rope stress raisers that cause with arc gantry crane ear, have simple in structure; It is little to take the machine room space; In light weight, arrange compactness, wire rope and arc door face board are close to; Good to medium-and-large-sized table hole arc door conformability, advantage such as safety measure is good.
