Detailed Description
The principles and features of the present utility model are described below with reference to the drawings, the examples are illustrated for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.
The embodiment provides a safety interlocking adjusting device, wherein the adjusting device is specially used for solving the problem of accurate adjustment of the height position of a locking pressing plate in a double-cover sealing device with a safety interlocking function in the nuclear power field.
In the scheme, the provided safety interlocking adjusting device comprises a compression bar mechanism and a pressure plate adjusting mechanism; the pressing plate adjusting mechanism is used for acting on the pressing rod mechanism. 1-5, a pressing plate adjusting mechanism is installed and fixed on the locking ring, the pressing plate adjusting mechanism is provided with a plate body 11, and the plate body 11 is configured to be capable of adjusting and positioning a pressing rod up and down in the vertical direction; it can be understood that the plate 11 in the scheme can be adjusted up and down, unlike the traditional welding mode, the plate 11 is designed to be capable of being positioned and adjusted in the vertical direction, and can be reasonably adjusted according to actual conditions; and is convenient for later use.
In the present embodiment, the cross section of the plate body 11 is provided in a variable thickness structure; specifically, the upper end surface of the plate 11 is a plane, and the lower end surface of the plate 11 is a wedge-shaped slope structure.
The pressing rod mechanism is provided with a pressing rod 21, the pressing rod 21 is arranged right below the plate body 11, and the upper end part of the pressing rod 21 is contacted with the lower end surface of the plate body 11; in a specific use process, as long as the locking ring rotates, the pressing plate adjusting mechanism rotates synchronously with the locking ring, and the thickness of the plate body 11 contacted with the upper end part of the pressing rod 21 changes, so that the pressing rod 21 is forced to move up and down for interlocking adjustment.
It can be understood that the lower end surface of the plate 11 is designed into a wedge-shaped slope structure, so long as the locking ring rotates, the plate 11 rotates synchronously, and the rotation of the plate 11 can cause the lower end surface of the plate 11 to gradually press the pressing rod 21 until the thicker part of the lower end surface of the plate 11 presses the pressing rod 21; the pressing rod 21 is abutted against the end face of the lower flange at this time, so that the locking of the lower flange is realized.
In order to describe the device in more detail, the specific composition of the platen adjustment mechanism and the plunger mechanism is described in detail below.
In this embodiment, the platen adjustment mechanism further includes a support frame 12 and an adjustment assembly; the support frame 12 is fixed to the locking ring mentioned above; therefore, only the locking ring rotates, the support frame 12 drives the whole pressing plate adjusting mechanism to rotate; the adjusting component is movably connected with the supporting frame 12; the plate body 11 is fixed with the adjusting component; that is, the plate 11 is connected to the support frame 12 by the adjusting assembly, so that the plate 11 moves synchronously to adjust the compression bar as long as the adjusting assembly moves relative to the support frame 12.
It will be appreciated that the ability of the plate 11 to be adjusted in the vertical direction is accomplished by the adjustment assembly herein.
Specifically, in the embodiment of the present solution, the supporting frame 12 has a "7" structure, and specifically includes a vertical plate 121 and a horizontal plate 122; and, the adjusting assembly includes adjusting screw 13, adjusting nut 14 and lock nut 15; a mounting hole is formed in the transverse plate 122, and the adjusting screw 13 passes through the mounting hole; the adjusting nut 14 is screwed with the adjusting screw 13 and is positioned above the transverse plate 122; the lock nut 15 is screwed with the adjusting screw 13 and is positioned below the transverse plate 122; the plate 11 is fixed to the lower end of the adjusting screw 13.
The specific operation mode is as follows: when the adjusting nut 14 is rotated clockwise or anticlockwise and the locking nut 15 is loosened, the adjusting screw 13 can be utilized to drive the plate 11 to slide up and down, so that the accurate adjustment of the height position of the plate 11 is realized. After the height position of the plate 11 is adjusted in place, the lock nut 15 is tightened, so that the current height position of the plate 11 can be locked under the combined action of the lock nut 15 and the adjusting nut 14.
In this scheme, in order to guarantee the stability of plate 11 in the upper and lower regulation in-process, we have still set up guide assembly here, also set up on support frame 12 and install guide assembly promptly, and plate 11 is through guide assembly steady reciprocates. Specifically, the guide assembly includes a guide groove 16 and a guide block 17; the guide groove 16 is provided at an end surface of the vertical plate 121 facing the plate body 11; the guide block 17 is built in the guide groove 16, and the guide block 17 is fixedly connected with the side surface of the plate body 11.
When the plate 11 is adjusted up and down, the guide block 17 is driven to slide up and down in the guide groove 16, so that the stability of the plate 11 in the adjusting process is ensured.
In this embodiment, the proposed compression bar mechanism further comprises a cylinder 22 and a spring 23; the above-mentioned pressing lever 21 is nested in the cylinder 22, and is elastically connected with the cylinder 22 by a spring 23; the two ends of the compression bar 21 extend out of the cylinder 22 respectively; during operation, the plate 11 is pressed onto the compression bar 21, and at the same time the spring 23 is compressed and the lower end of the compression bar 21 extends downwards to lock with the lower flange.
In this embodiment, the compression bar 21 includes a bar body 211 and a limit flange 212 disposed at a middle position of the bar body; meanwhile, the cylinder 22 comprises a cylinder body 221 and a sealing cover 222, a first containing cavity and a second containing cavity are arranged in the cylinder body 221, and the spring 23 is sleeved on the rod body 211 and is simultaneously arranged in the first containing cavity with the limit flange 212; the plugging end of the cover 222 is plugged with the second accommodating cavity.
Therefore, as will be apparent from the above description, the main function of the compression bar 21 is to lock the lower flange against rotation. The main principle is as follows: the pressing plate adjusting device is fixed on the locking ring, and the part of the pressing plate adjusting device, which is contacted with the pressing rod 21, is a plate body 11 with a certain inclination (wedge block). When the locking ring rotates, the plate 11 at the contact part with the compression bar 21 gradually presses the compression bar 21, thereby forcing the compression bar 21 to move up and down in the cylinder; when the locking ring rotates reversely, the pressing force of the plate 11 to the pressing rod 21 is gradually reduced, and the pressing rod 21 is reset under the rebound action of the spring 23.
Therefore, by adopting the scheme, the height position of the former plate 11 cannot be adjusted, the accurate adjustment between the plate 11 and the compression bar 21 cannot be realized, and the function can be realized now, so that the locking function of the compression bar 21 can be better exerted.
The technical scheme solves the problem of accurate adjustment of the height position of the locking pressing plate in the double-cover sealing device with the safety interlocking function in the nuclear power field. Meanwhile, the device has a simple structure, and can conveniently and accurately adjust the height position of the locking pressing plate, thereby effectively ensuring the reliability of the safety locking device.
