The vertical disc strand head of cabler
Technical field
The present invention relates to field of mechanical technique, especially relate to a kind of structural improvement that the dish of cabler is twisted head.
Background technology
At present, generally the dish of the cabler of Shi Yonging strand head all is horizontal basically, and promptly the axis of stranding rotating disk is and is horizontally disposed with.In order to improve the quality of product, the length that prolongs disposable stranding as far as possible, people have carried out long-term exploration, have proposed diversified embodiment.
For example, Chinese patent literature discloses a kind of wire twisting machine disc strand head (200420024471.8), the bearing disc that comprises a ring plate-like, fix a forked frame on the bearing disc, jaw one end of forked frame is connected with the main shaft of a blank pipe shape, and the forked frame that main shaft is positioned at the port of forked frame place one side is provided with the guide roller set that the pilot cable line moves, and the intersection end of described forked frame is provided with take-up reel, bearing disc is provided with bus cable device, and the bottom of bearing disc is provided with support roller.The somebody has applied for frame winch strand body (application number: patent 200420026936.3) by name, the strand body comprises the framework at middle part and capstan winch and the hollow rotating shaft and the drum clamping device at two ends, be distributed in the same periphery drum gross mass of cable in the time of can effectively reducing same group of center line clamping apparatus for disc and use drum clamping device three equal parts on the same group.
Though such scheme has improved the performance of cabler to a certain extent, prolonged stranding length one time, because its intrinsic design defect, the raising of its performance is limited.Its reason is to increase the length of a stranding, and the drum weight that is placed on the stranding rotating disk must increase, and horizontal stranding rotating disk hangs thereon owing to drum, thereby can't bear excessive weight.Also the someone adopts the size that increases the stranding rotating disk, uses the higher schemes such as material of intensity instead, though can increase stranding length to a certain extent one time, also the phase strain is big for cost of manufacture, driving power consumption etc.
In addition, the back twist in the stranding process also is that bigger, present back twist device is difficult to keep the unanimity of back twist when the back twist of some one-tenth cables is operated to the influence of stranding quality, makes that the twist of indivedual one-tenth cables is inconsistent.
Summary of the invention
The purpose of this invention is to provide a kind of reasonable in designly, simple in structure, disposable stranding length is big, the vertical disc strand head of cabler easy for operation; Solved the existing in prior technology complex structure, it is very unreasonable to design, and disposable stranding length is short, manipulates very convenient etc. technical problem.
It is reasonable in design that another object of the present invention provides a kind of back twist device, and each becomes cable back twist unanimity, the vertical disc strand head of the cabler that synchronism is good; Be difficult to keep the consistent shape of back twist when having solved existing in prior technology back twist operation, the technical problem of the inconsistent grade of the twist of feasible indivedual one-tenth cables.
The present invention also have a purpose to provide a kind of making and operating cost low, be easy to promote, kinetic equation loss is few, the vertical disc strand head of the cabler that transmission efficiency is high; Solve existing in prior technology and made and operating cost high the technical problem of the big grade of power transmission loss.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals: the vertical disc strand head of cabler, comprise the stranding operating platform, stranding doubling mould bases provided thereon, side at stranding doubling mould bases is provided with deflecting roller, below stranding doubling mould bases, be provided with support, the central shaft of this support and stranding rotating disk is matched, it is characterized in that in the axis of described central shaft vertical mutually with horizontal plane, be provided with some cable pay off racks on the stranding rotating disk, the matched dish axle of described cable pay off rack and cable hank is vertical mutually with the axis of stranding rotating disk.
The present invention has creatively adjusted the layout orientation of existing stranding rotating disk, has overcome the inherent shortcoming of existing design, and its ability of bearing cable hank weight is improved, thereby has realized the remarkable increase of disposable stranding length.And, simplified device structure, be convenient to assembling, operation.Deflecting roller is used to change over the direction of cable, makes into cable and can successfully be delivered to all the other stranding equipment.Certainly, deflecting roller also can independently be provided with.
For back twist, as preferably, described each cable pay off rack is located at respectively on the back twist rotating disk, and described back twist rotating disk is matched by rotating shaft and stranding rotating disk.
In order to guarantee the synchronism of back twist, improve the stranding quality, as preferably, described central shaft is provided with the back twist driven wheel, described back twist driven wheel and some idler gear engagements of evenly arranging, described idler gear meshes with travelling gear respectively, and each travelling gear matches by the rotating shaft of conveyer belt with the back twist rotating disk.
As preferably, described each travelling gear matches with each rotating shaft of one group of back twist rotating disk respectively by some conveyer belts.
In order to improve the automation of operation degree, as preferably, described stranding rotating disk bottom is provided with transmitting gear, and described transmitting gear is meshed with driven wheel, and described driven wheel is matched by transmission tooth case and drive motors.
Because place, the axle center of back twist rotating disk is fixing, and the edge does not have supporting construction, long-time use causes the damage of back twist rotating disk easily, as preferably, is provided with some little roller frames below the edge of described back twist rotating disk, is respectively arranged with little support roller on little roller frame.The little roller frame here can be arranged on the stranding rotating disk, also can connect on the back twist rotating disk.
Based on the same reason of above-mentioned back twist rotating disk, as preferably, be provided with some big supporting wheel framves below the edge of described stranding rotating disk, on the big supporting wheel frame, be respectively arranged with big supporting wheel.The big supporting wheel frame here can be arranged on the ground of stranding rotating disk below, also can connect on the stranding rotating disk.Because the diameter of stranding rotating disk is bigger, all the other positions below the stranding rotating disk also can be provided with the big supporting wheel frame.
In order to brake easily,, be provided with a pneumatically operated brake below the edge of described stranding rotating disk at least as preferably.The pneumatically operated brake here adopts the mode of generally using at present, for example cylinder jacking, electromagnetically operated valve etc.Owing to be technique known, this paper does not give unnecessary details.
As preferably, 1~4 group of back twist rotating disk is set on the described stranding rotating disk, described every group of back twist rotating disk comprises the back twist rotating disk of 2~4 different-diameters.
In addition, as preferably, described support is provided with some crossbeams, is provided with some support line bodies on crossbeam.Support line body is used for guiding and respectively becomes cable to the stranding mould bases.
Therefore, the present invention has following advantage: 1, reasonable in design, simple in structure, disposable stranding length is big, be increased to about 15km from the 1km of prior art, and also easy for operation; 2, the back twist device is reasonable in design, and each becomes cable back twist unanimity, and synchronism is good; 3, making and operating cost are low, are easy to promote, and kinetic equation loss is few, and the transmission efficiency height is particularly useful for the making of submarine fiber cable.
