Abstract
The utility model discloses a rotating connector. A section of a diameter enlargement which is processed with outer screw threads is arranged above a fixed shaft, and an annular boss is arranged on an outer surface of a rotary shaft. The lower end of the rotary shaft is inserted in the diameter enlargement of the fixed shaft, a sealing ring is arranged between radial clearances of two shafts, and a connecting nut is sheathed on the boss of the rotary shaft; the inner screw threads are connected with the outer screw threads on the fixed shaft, and steel balls which are evenly distributed along the circumference are all arranged between the fixed shaft and the rotary shaft and between the rotary shaft boss and the connecting nut. The use of the connector can keep a cooling pipeline of a continuous casting steel ladle weighing electronic balance sensor smooth, and the work reliability of an electronic balance and the service life of the sensor are improved.
Description
The utility model relates to the rotating joint on a kind of low pressure transfer conduit that is used for low speed rotation, specifically a kind of rotating joint that is used on the continuous casting steel bag weighing electronic scale sensor cooling line.
In the prior art, the mechanical part of continuous casting steel bag weighing electronic scale is placed on the revoliving arm of bale panoramic tables.For adopting pressurized air to cool off to the sensor in its mechanical part, pressurized air is through rubber hose is guided to pipeline on the revoliving arm from traverse platform pedestal center.Under the nominal situation, revoliving arm back and forth rotates by 180 °, and this flexible hose can satisfy job requirement.But owing to reasons such as traverse platform maintenance and staff's misoperations, make the revoliving arm folk prescription to continuous rotation through regular meeting, cause to connect that rubber hose is wound into knot or strand is disconnected, pressurized air interrupts, and makes the electronic scale can't proper functioning, has shortened the working life of sensor.
The purpose of this utility model provides a kind of rotating joint, makes at the continuous folk prescription of revoliving arm when rotating, and the fault that pressurized air interrupts also can not occur, and guarantees the electronic scale proper functioning, improves the working life of sensor.
The purpose of this utility model is to realize like this.
A kind of rotating joint, stationary axle and running shaft with tubular shape, the top of stationary axle has one section and is processed with externally threaded enlarged-diameter part, has an annular boss on the running shaft outer surface, running shaft and stationary axle axis coincide, insert in the enlarged-diameter part of stationary axle its lower end, between the diaxon radial clearance seal ring is installed, coupling nut is sleeved on the running shaft boss, the outside thread of its internal thread and stationary axle top links, between stationary axle and the running shaft, between running shaft boss and the coupling nut steel ball of evenly arranging along circumference is housed all.
One turning handle is installed on the running shaft, and the turning handle end radially has groove along running shaft, is used to promote the driving lever that turning handle rotates, and the one end places the groove middle part perpendicular with groove.
Stationary axle upper end, running shaft lower end are sealing, offer suction port on the stationary axle, offer the air outlet on the running shaft.
The advantage that the utility model is compared with prior art had is: the use of this rotating joint, and can make compressed air line keep unimpeded, improve the functional reliability of continuous casting steel bag weighing electronic scale and the working life of sensor.This rotating joint also has simple in structure, is easy to advantages such as manufacture, installation, maintenance.In addition, owing to being used of turning handle, driving lever structure, making this rotating joint have and compensate the ability that it makes alignment error automatically.
Introduce embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is the structural drawing of the utility model rotary connector.
Fig. 2 is the practical application condition diagram of the utility model rotary connector.
As shown in Figure 1, the utility model rotary connector mainly is made of stationary axle 1, seal ring 2, coupling nut 3, steel ball 4, key 5, running shaft 6, turning handle 8 and driving lever 9.Stationary axle 1 and running shaft 6 are all tubular shape.The lower end of stationary axle 1 is sealed, and the top has one section and is processed with externally threaded enlarged-diameter part.The upper end of running shaft 6 is sealed, and has an annular boss on the outer surface.Offer suction port 10 on the stationary axle 1, cross the air outlet 7 that diameter has two symmetries on the running shaft 6.Running shaft 6 coincides with stationary axle 1 axis, and insert in the enlarged-diameter part of stationary axle 1 its lower end, between the radial clearance of running shaft 6 and stationary axle 1 seal ring 2 is installed.Coupling nut 3 is sleeved on the boss of running shaft 6, and the outside thread of its internal thread and stationary axle 1 top links.Between stationary axle 1 and the running shaft 6, between running shaft 6 boss and the coupling nut 3 steel ball 4 that is uniformly distributed along the circumference is housed all.Be set with a turning handle 8 on the running shaft 6, by key 5 both are fixed, turning handle 8 ends radially have groove along running shaft 6, are used to promote the driving lever 9 rectangular shapes that turning handle 8 rotates, and itself and running shaft 6 parallel axes also promptly place in the middle part of turning handle 8 grooves with the perpendicular end of groove.
In actual the use, the stationary axle 1 of rotating joint is weldingly fixed on continuous casting traverse platform 11 pedestals, and its axis and revoliving arm 12 rotational axis coincide, and the other end of driving lever 9 is fixed on the revoliving arm 12, sees Fig. 2.Suction port 10 is connected with compressed air gas source, and air outlet 7 is connected with gas piping 13 on the revoliving arm 12.Pressurized air is through this rotating joint, delivers to the sensor of electronic scale mechanical part 14 by gas piping 13, and it is cooled off.During revoliving arm 12 revolutions, by 6 rotations synchronous of driving lever 9 driving handles 8 driven rotary axles with it, air outlet 7 and the relative position between the gas piping 13 that maintenance is arranged on the running shaft 6 are constant all the time, make compressed-air actuated transmission not be subjected to the influence of revoliving arm 2 gyratory directions, remain unimpeded.In addition, the rotation of running shaft 6 promotes turning handle 8 by driving lever 9 and realizes, because driving lever 9 places the end in turning handle 8 grooves can be along the groove slide relative, thereby have between compensation rotation coupling running shaft 6 rotational axis and revoliving arm 12 rotational axis because of the ability of the error that manufacturing produces is installed.
The utility model rotating joint also can be used as the rotating joint on other various low speed low pressure transfer conduit.
