Abstract
The invention discloses a pneumatic loading arm steering joint and belongs to the technical field of loading arms. The joint comprises a steering tube, a tube seat, a pneumatic motor, a transmission device, a lower flange, first planar balls, an inner tube, second planar balls and an upper flange, wherein the pneumatic motor is fixed on the tube seat, the lower flange is fixed at the lower end of the inner tube, the inner tube is sleeved with the steering tube, and upper and lower outer circumferences of the inner tube are rotationally connected with the steering tube through the second planar balls and the first planar balls respectively; the upper flange coaxial with the inner tube is arranged at the upper end of the steering tube, the transmission device comprises a worm gear and a worm, the worm gear is fixed on the outer circumference of the steering tube, and the pneumatic motor is in driving connection with the worm which is in meshed connection with the worm gear. With the adoption of the joint, the inner tube in the steering center can be prevented from shifting, so that the sealing effect is improved, friction forces among contact surfaces of movable parts are small, rotation is convenient and flexible, steering of a steering knuckle can be controlled actively, and the steering knuckle rotates automatically.
Description
Technical field
The invention belongs to oil filling riser technical field, more particularly, relate to a kind of Pneumatic crane tube steering knuckle.
Background technique
At present, the knuckle used in loading and unloading arm, it includes steering tube base, and the knuckle inner chamber of coupled locking nut and knuckle main part composition, is equipped with steering tube, Plane Ball, look nut and locking nut in chamber from the bottom to top successively.In practicality, be located at the O RunddichtringO between steering tube and steering tube base, poor flexibility, hard contact, large, easy oil leakage of wearing and tearing; Steering tube and look nut, locking nut threaded connection place, knuckle main part and steering tube base threaded connection place, locking nut and knuckle main part matching gap place, without sealing, and in chamber, inject lubricating grease trouble, long-time use is easily aging, cold-weather lubrication effect is particularly bad, and existing knuckle does not have active driving device, and the rotation of knuckle does not realize automation.
Summary of the invention
the problem that 1, will solve
For the above-mentioned problems in the prior art, the invention provides a kind of Pneumatic crane tube steering knuckle, it can ensure the interior pipe invariant position of turning center, improve sealing effect, and frictional force between movable part surface of contact is little, rotate light and flexible, and can the turning to of ACTIVE CONTROL knuckle, thus realize the automation that knuckle rotates.
2, technological scheme
In order to solve the problem, the technical solution adopted in the present invention is as follows:
A kind of Pneumatic crane tube steering knuckle, comprise steering tube, base, pneumatic motor, transmission device, lower flange, the first Plane Ball, interior pipe, the second Plane Ball, upper flange, described pneumatic motor is fixed on described base, the lower end of described interior pipe is fixed with lower flange, described interior pipe box in described steering tube, and correspondingly respectively at the place of excircle up and down of interior pipe to be rotationally connected by the second Plane Ball and the first Plane Ball and described steering tube; The upper end of described steering tube is provided with the upper flange coaxially arranged with described interior pipe, described transmission device comprises turbine and worm screw, the excircle of described steering tube is fixed with coaxial turbine arranged with it, and described pneumatic motor drives and is connected with worm screw, and described worm screw is connected with described turbine is meshing.
Preferably, described upper flange, lower flange and interior pipe are all coaxially arranged, and intracavity diameter size is identical.
Preferably, circular seal connecting groove is provided with in described upper flange.
3, beneficial effect
Compared to prior art, beneficial effect of the present invention is:
The present invention can ensure the interior pipe invariant position of turning center, drastically increase its sealing effect, the whole immersion oil of moving part, anti-corrosion capacity is strong, substantially prolongs the working life of knuckle, and frictional force between movable part surface of contact is little, rotate light and flexible, the present invention can also the turning to of ACTIVE CONTROL knuckle, thus realize the automation that knuckle rotates, and have structure simple, easy to assembly, reasonable in design, be easy to the advantage that manufactures.
Accompanying drawing explanation
