Description
Technical Field
The present disclosure relates to the field of mechanical technology, and in particular, to a support device for a rotary joint.
Background
The rotary joint is a pipeline connecting device and can relatively rotate when being connected with a pipeline. The rotary joint has a compact structural design. The field of application of rotary joints is very wide and covers various manufacturing industries, such as: metallurgy, machine tools, power generation, petroleum, rubber, plastics, textile, printing and dyeing, pharmacy, cigarette, papermaking, food, feed processing and the like.
The rotary joint adopts flange connection and can be integrated into the rotary kiln. In the prior art, the rotary joint supporting device is hard-connected, and the connecting mode can play a role in stabilizing and supporting, but cannot compensate the movement of the rotary joint, so that the overall stability of the equipment is not high, and the service life is shortened.
Disclosure of Invention
The present disclosure is directed to overcoming the shortcomings of the prior art, and providing a supporting device for a rotary joint, which can reduce the up-down movement of the rotary joint.
According to one aspect of the present disclosure: the support device for the rotary joint comprises a bracket, a sliding support, a sliding shaft, a bracket and an elastic piece; the bracket is used for fixedly connecting with the rotary joint; the bracket is connected to the sliding support, and the bracket is positioned below the sliding support; the elastic piece is arranged between the bracket and the sliding support and is used for providing upward elastic supporting force for the sliding support; one of the sliding support and the bracket is provided with a limiting hole, the other is fixedly connected with the sliding shaft, and the sliding shaft is inserted into the limiting hole and can slide up and down.
According to one embodiment of the present disclosure, the elastic member is a spring.
According to one embodiment of the disclosure, the sliding shaft is inserted into the elastic member.
According to one embodiment of the present disclosure, the limiting hole is provided in the bracket.
According to one embodiment of the present disclosure, the aperture of the limiting hole is larger than the shaft diameter of the sliding shaft.
According to one embodiment of the present disclosure, the aperture of the limiting hole is 5% -10% larger than the shaft diameter of the sliding shaft.
According to one embodiment of the disclosure, the bracket is connected with the sliding support through a sliding block.
According to one embodiment of the present disclosure, the upper surface of the slider is fixedly connected to the bracket, and the slider is made of an elastic material.
According to one embodiment of the present disclosure, the bracket is connected to the rotary joint by a bolt.
In the supporting device of the rotary joint provided by the embodiment of the disclosure, the rotary joint can be fixedly connected with the bracket, and the bracket is connected with the sliding support, so that the up-and-down movement of the rotary joint can be transmitted to the sliding support. The sliding shaft can slide up and down in the limiting hole, so that the distance between the sliding support and the bracket can be changed, and the compression degree of the elastic piece can be changed. When the rotary joint moves downwards, the sliding support can move downwards. The distance between the sliding support and the bracket is reduced; at this time, the elastic piece is compressed to a greater extent to provide a greater rebound force for the sliding support, so as to inhibit downward movement of the sliding support, and further reduce the downward movement amplitude of the rotary joint. When the rotary joint moves upwards, the sliding support can move upwards; at this time, the degree to which the elastic member is compressed is reduced, the elastic force provided by the elastic member to the sliding support is reduced, and then the upward movement amplitude of the sliding support is reduced, and further the upward movement amplitude of the rotary joint is restrained. Therefore, the supporting device of the rotary joint can buffer the movement of the rotary joint, so that the stability and the service life of equipment applying the supporting device are improved.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.

The disclosed embodiments provide a support device for a rotary joint, comprising: the device comprises a bracket 4, a sliding support 3, a sliding shaft 8, a bracket 1 and an elastic piece 2.
The bracket 4 is used for fixedly connecting the rotary joint 6;
the bracket 4 is connected to the sliding support 3, and the bracket 1 is positioned below the sliding support 3;
the elastic piece 2 is arranged between the bracket 1 and the sliding support 3 and is used for providing upward elastic supporting force for the sliding support 3;
one of the sliding support 3 and the bracket 1 is provided with a limiting hole, the other is fixedly connected with the sliding shaft 8, and the other end of the sliding shaft 8 is inserted into the limiting hole and can slide up and down.
In the supporting device provided by the embodiment of the disclosure, the rotary joint 6 may be fixedly connected with the bracket 4, and the bracket 4 is connected with the sliding support 3, so that the up-and-down movement of the rotary joint 6 may be transferred to the sliding support 3. The sliding shaft 8 can slide up and down in the limiting hole, which allows the distance between the sliding support 3 and the bracket 1 to be changed, and thus allows the degree of compression of the elastic member 2 to be changed.
When the rotary joint 6 is moved downward, the slide mount 3 can be moved downward. The distance between the sliding support 3 and the bracket 1 is reduced; at this time, the elastic member 2 is compressed to a greater extent to provide a greater repulsive force to the shoe 3, thereby suppressing downward play of the shoe 3, and thus reducing the downward play amplitude of the rotary joint 6. When the rotary joint 6 moves upwards, the sliding support 3 can move upwards; at this time, the degree to which the elastic member 2 is compressed is reduced, the elastic force provided by the elastic member 2 to the slide mount 3 is reduced, and the upward play of the rotary joint 6 is suppressed.
Meanwhile, in this embodiment, one of the sliding support 3 and the bracket 1 has a limiting hole, and the other is fixedly connected with the sliding shaft 8, and the other end of the sliding shaft 8 is inserted into the limiting hole and can slide up and down; this makes it possible for the sliding shaft 8 to also limit the horizontal offset of the sliding support 3 so that the sliding support 3 does not undergo a substantial horizontal offset, so that the play of the sliding support 3 is mainly concentrated in the vertical direction.
In this way, the support device of the rotary joint can reduce the play of the rotary joint 6, improve the stability and the service life of the equipment using the support device.
In one embodiment of the present disclosure, the bracket 4 is connected to the swivel joint 6 by a bolt 5.
In one embodiment of the present disclosure, the upper end of the sliding shaft 8 is fixedly connected to the sliding support 3, for example welded or screwed.
In the embodiment of the present disclosure, in one example, the number of the sliding shafts 8 is 4, and four sliding shafts 8 are distributed in a square shape. In another example, the number of sliding shafts 8 is 3, and three sliding shafts 8 are distributed in a triangle shape, which can improve the stability of the supporting device. It will be appreciated that in other embodiments of the present disclosure, the number of sliding shafts 8 may be other, and the arrangement may be other.
In one embodiment of the present disclosure, the elastic member 2 is a spring, such as a cylindrical spring, a belleville spring, a ring spring, a coil spring, or the like.
In one embodiment of the present disclosure, the number of elastic members 2 is one or more. The number of elastic members 2 can be adjusted according to the amount of the movement of the rotary joint 6. It will be appreciated that the greater the number of elastic members 2, the better the play-suppressing effect.
In one embodiment of the present disclosure, the elastic member 2 is disposed coaxially with the sliding shaft 8, and the sliding shaft 8 penetrates the elastic member 2. Thus, the sliding shaft 8 can also play a role in fixing the elastic piece 2, and the elastic piece 2 is prevented from slipping.
In another embodiment of the present disclosure, the elastic member 2 is provided at a different position from the sliding shaft 8. In this way, the positions and the number of the elastic members 2 and the slide shafts 8 can be adjusted independently of each other as needed.
For example, the elastic member 2 and the sliding shaft 8 may be disposed on the left and right sides of the lower portion of the sliding support 3, respectively. The number of elastic members 2 may be set to 4, and the number of sliding shafts may be set to 2. The positions of the two can be exchanged, and the number can be adjusted according to the needs.
In one embodiment of the present disclosure, a limiting hole is provided on the bracket 1, and the lower end of the sliding shaft 8 is inserted into the limiting hole of the bracket 1 and can slide up and down in the limiting hole. The upper end of the sliding shaft 8 is fixedly connected with the sliding support 3.
In one embodiment of the present disclosure, the aperture of the limiting hole of the bracket 1 is larger than the shaft diameter of the sliding shaft 8. Further, the aperture of the limit hole of the bracket 1 is 5% -10% larger than the shaft diameter of the sliding shaft 8. For example, the aperture of the limit hole of the bracket 1 is 64mm (diameter), and the shaft diameter of the sliding shaft 8 is 60mm (diameter).
In this embodiment, the diameter of the stopper hole of the bracket 1 is larger than the shaft diameter of the slide shaft 8. The sliding shaft 8 can be shifted in the horizontal direction to a certain extent, and the sliding shaft 8 is fixedly connected with the sliding support 3, so that the sliding support 3 can also be shifted in the horizontal direction. The limiting hole of the bracket 1 can enable the sliding shaft 8 to deviate in the horizontal direction, so that the sliding support 3 can be allowed to have certain play in the horizontal direction, and hard connection between the rotary joint 6 and the bracket 1 in the horizontal direction is avoided.
In another embodiment of the present disclosure, a limiting hole is provided on the sliding support 3, and an upper end of the sliding shaft 8 is inserted into the limiting hole of the sliding support 3 and can slide up and down in the limiting hole. The lower end of the sliding shaft 8 is fixedly connected with the bracket 1. Optionally, the fixed connection mode is as follows: and (5) welding and screwing.
For example, the aperture of the limit hole of the sliding support 3 is 64mm (diameter), and the shaft diameter of the sliding shaft 8 is 60mm (diameter).
The difference between the aperture of the limit hole of the sliding support 3 and the shaft diameter of the sliding shaft 8 can influence the horizontal offset of the sliding shaft 8. The larger the difference between the two, the larger the offset of the sliding shaft 8 in the horizontal direction, and vice versa. In one embodiment of the present disclosure, the thickness of the sliding support 3 is 30mm. As the depth of the limiting hole on the sliding support 3 becomes deeper, the offset of the sliding shaft 8 in the horizontal direction becomes smaller.
In one embodiment of the present disclosure, the bracket 4 is connected to the sliding support 3 through a slider 7. The upper surface of the slide block 7 is fixedly connected with the bracket 4 by welding, threads and the like.
Optionally, the number of sliders 7 is one or more.
In one embodiment of the present disclosure, the slider 7 is made of an elastic material, such as rubber or the like.
In one embodiment of the present disclosure, the bracket 4 is fixedly connected with the rotary joint 6, and the upper surface of the slider 7 is fixedly connected with the bracket 4. The movement of the rotary joint 6 is transmitted to the bracket 4, so that the bracket 4 generates movement in the horizontal direction; this causes the slider 7 to slide on the slide mount 3, and the sliding of the slider 7 generates a frictional force that hinders the sliding of the slider 7 in the horizontal direction. This can reduce the play of the bracket 4 in the horizontal direction, and further reduce the play of the rotary joint 6 in the horizontal direction. The vertical movement of the bracket 4 presses the sliding block 7, and the sliding block 7 is made of elastic materials and can generate elastic deformation. The elastic deformation of the sliding block 7 can buffer the movement of the bracket 4 in the vertical direction, and further reduce the movement of the rotary joint 6 in the vertical direction.
The presently disclosed embodiments also provide a rotary kiln provided with a rotary joint 6 and any of the support devices described in the support device embodiments above. The rotary joint 6 can be fixed on a supporting device, the supporting device can compensate the movement of the rotary joint 6, the movement amount of the rotary joint 6 is reduced under the condition that the rotary joint 6 can move, certain soft connection is realized, and the stability reduction and the service life reduction of the rotary kiln caused by hard connection are avoided.
Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This application is intended to cover any adaptations, uses, or adaptations of the disclosure following, in general, the principles of the disclosure and including such departures from the present disclosure as come within known or customary practice within the art to which the disclosure pertains.
