The purpose of the invention can be realized by the following technical scheme:
the utility model provides a quick replacement rotary joint's appurtenance, the rotary joint top is provided with the oil inlet, the bottom is provided with the connector, one side is provided with the oil-out, includes the double-screw bolt, the double-screw bolt sets up in the oil inlet, be provided with the end cap in the oil-out, be provided with the screw rod in the connector, connector opening part is provided with sealed the pad, sealed pad bottom spiro union has quick-operation joint, the double-screw bolt uses with the screw rod cooperation.
As a further scheme of the invention: and a sealing ring is also arranged between the sealing gasket and the connecting port.
As a further scheme of the invention: the sealing gasket is connected with the rotary joint through a bolt.
As a further scheme of the invention: one end of the stud is in threaded connection with the oil inlet, one side, located outside the oil inlet, of the stud is of an outer hexagonal structure, and a concave hole is formed in the center of one side, located inside the oil inlet, of the stud.
As a further scheme of the invention: the top end of the screw rod is provided with a protruding structure, and the bottom end of the screw rod is provided with a recessed structure.
As a further scheme of the invention: the concave hole is matched with the convex structure for use.
The invention has the beneficial effects that:
the invention provides a set of auxiliary tools suitable for dismounting a rotary joint and testing air tightness, and the rotary joint can be quickly and efficiently dismounted. The stud plays a role in sealing and serving as a supporting point; when the rotary joint is disassembled, the screw rod protruding structure is aligned to the concave hole of the stud, the support point is aligned to the concave structure of the screw rod by using the puller, and the damaged bearing is quickly taken out by the puller.
After the bearing is replaced, the airtightness of the rotary joint needs to be detected. The oil inlet is sealed by a stud, the oil outlet is sealed by a plug, and the connecting port is cooperatively sealed by a sealing gasket and a sealing ring. The threaded hole of ann commentaries on classics quick-operation joint is left to sealed the below, and after the installation, places the aquatic with rotary joint, utilizes the quick-operation joint of sealed pad below to let in compressed air, observes whether aquatic has the bubble, reaches the effect that detects the rotary joint gas tightness.
Drawings
The invention will be further described with reference to the accompanying drawings;
FIG. 1 is a schematic view of an overall structure of an auxiliary tool for rapidly replacing a rotary joint;
FIG. 2 is a block diagram of the disassembled bearing of the present invention;
FIG. 3 is a schematic view of the upper half of the swivel of the present invention;
FIG. 4 is a schematic view of the lower half of the swivel joint of the present invention;
fig. 5 is a schematic view of a rotary joint of the present invention.
In the figure: 1. a stud; 2. a rotary joint; 3. a plug; 4. a seal ring; 5. a gasket; 6. a bolt; 7. a screw; 8. a quick coupling; 9. an oil inlet; 10. an oil outlet; 11. and (7) connecting ports.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-5, an auxiliary tool for quickly replacing a rotary joint is disclosed, in which an oil inlet 9 is disposed at the top of the rotary joint 2, a connection port 11 is disposed at the bottom of the rotary joint, and an oil outlet 10 is disposed at one side of the rotary joint. Appurtenance includes double-screw bolt 1, and 1 one end of double-screw bolt and 9 threaded connection of oil inlet, and double-screw bolt 1 is located 9 outside one sides of oil inlet and is provided with the shrinkage pool for outer hexagonal structure, the inside one side center department that is located oil inlet 9. A plug 3 is connected in the oil outlet 10 through screw threads. The screw 7 is arranged in the connecting port 11, the opening of the connecting port 11 is fixedly connected with a sealing gasket 5 through a bolt 6, a sealing ring 4 is further arranged between the sealing gasket 5 and the connecting port 11, and the bottom of the sealing gasket 5 is in threaded connection with a quick coupling 8. The top end of the screw rod 7 is provided with a convex structure, and the bottom end of the screw rod is provided with a concave structure. The concave hole is matched with the convex structure for use.
The working principle is as follows:
the stud 1 of the invention plays a role in sealing and serving as a supporting point; the oil outlet 10 is blocked by the plug 3, the protruding structure of the screw 7 is aligned to the concave hole of the stud 1 when the rotary joint 2 is disassembled, the support point is aligned to the concave structure of the screw 7 by using the puller, and the damaged bearing is easily taken out through the puller.
