Detailed Description
The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the invention.
The embodiment provides a safety interlocking adjusting device which 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 field of nuclear power.
In the scheme, the safety interlocking adjusting device comprises a pressure lever mechanism and a pressure plate adjusting mechanism; the pressure plate adjusting mechanism is used for acting on the pressure rod mechanism. Specifically, referring to fig. 1 to 5, a pressing plate adjusting mechanism is fixedly mounted on the locking ring, the pressing plate adjusting mechanism has a plate body 11 therein, and the plate body 11 is configured to be capable of vertically adjusting and positioning the pressing rod; it can be understood that the plate body 11 of the scheme can be adjusted up and down, and different from the traditional welding mode, the plate body 11 is designed to be positioned and adjusted in the vertical direction, and can be reasonably adjusted according to actual conditions; meanwhile, the utility model is convenient for the later use.
In the present embodiment, the plate body 11 is provided with a variable thickness in cross section; specifically, the upper end surface of the plate body 11 is a plane, and the lower end surface of the plate body 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 using process, as long as the locking ring rotates, the pressure plate adjusting mechanism synchronously rotates along with the locking ring, the thickness of the plate body 11 contacted with the upper end part of the pressure rod 21 changes, and therefore the pressure rod 21 is forced to move up and down to carry out interlocking adjustment.
It can be understood that, the lower end surface of the plate body 11 is designed to be a wedge-shaped slope structure, as long as the locking ring rotates, the plate body 11 will rotate synchronously, and the rotation of the plate body 11 will make the lower end surface of the plate body 11 press the pressing rod 21 gradually until the thicker part of the lower end surface of the plate body 11 presses the pressing rod 21; the pressure lever 21 at this time abuts against the end face of the lower flange, and the lower flange is locked.
To describe the apparatus in more detail, the specific components of the platen adjustment structure and the plunger mechanism will be described in detail.
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, as long as the locking ring rotates, the whole pressure plate adjusting mechanism is driven to rotate by the support frame 12; the adjusting component is movably connected with the support frame 12; the plate body 11 is fixed with the adjusting component; that is, the plate 11 is connected to the support frame 12 through the adjustment assembly, so that the plate 11 moves synchronously to adjust the pressing rod as long as the adjustment assembly moves relative to the support frame 12.
It will be understood that the vertical adjustment of the plate body 11 is accomplished by the adjustment assembly herein.
Specifically, in the embodiment of the present disclosure, the supporting frame 12 is in a "7" shape, and specifically includes a vertical plate 121 and a horizontal plate 122; and, the adjusting assembly includes an adjusting screw 13, an adjusting nut 14 and a lock nut 15; a mounting hole is formed in the transverse plate 122, and the adjusting screw 13 penetrates through the mounting hole; the adjusting nut 14 is screwed with the adjusting screw 13 and is positioned above the transverse plate 122; the locking nut 15 is screwed with the adjusting screw 13 and is positioned below the transverse plate 122; the plate body 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 counterclockwise and the locking nut 15 is loosened, the adjusting screw 13 can be used to drive the plate body 11 to slide up and down, thereby achieving accurate adjustment of the height position of the plate body 11. After the height position of the plate body 11 is adjusted to the proper position, the locking nut 15 is screwed, so that the height position of the current plate body 11 can be locked under the combined action of the locking nut 15 and the adjusting nut 14.
In this scheme, in order to guarantee the stability of plate body 11 in the up-down adjustment process, we have still set up the direction subassembly here, also set up the direction subassembly that installs on support frame 12 promptly, and plate body 11 steadily reciprocates through the direction subassembly. Specifically, the guide assembly comprises a guide groove 16 and a guide block 17; the guide groove 16 is arranged on the 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 body 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 body 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 plunger 21 is nested in the cylinder 22 and is elastically connected with the cylinder 22 by means of a spring 23; the two ends of the pressure lever 21 respectively extend out of the cylinder 22; in operation, the plate 11 is pressed against the press rod 21, while the spring 23 is compressed and the lower end of the press rod 21 is extended downward and locked with the lower flange.
In the scheme, the pressure lever 21 comprises a lever body 211 and a limit flange 212 arranged at the middle position of the lever body; meanwhile, the cylinder 22 comprises a cylinder body 221 and a sealing cover 222, a first accommodating cavity and a second accommodating cavity are arranged in the cylinder body 221, and the spring 23 is sleeved on the rod body 211 and is arranged in the first accommodating cavity together with the limiting flange 212; the mating end of the cover 222 mates with the second receptacle.
Therefore, as can be readily appreciated from the above description, the main function of the strut 21 is to lock the lower flange against rotation. The main principle is as follows: the pressure plate adjusting device is fixed on the locking ring, and the part of the pressure plate adjusting device, which is contacted with the pressure rod 21, is a plate body 11 with a certain inclination (wedge block). When the locking ring rotates, the plate body 11 at the contact part with the pressure rod 21 gradually presses the pressure rod 21, so that the pressure rod 21 is forced to move up and down in the cylinder; when the locking ring rotates reversely, the pressing force of the plate body 11 on the pressing rod 21 is gradually relieved, and the pressing rod 21 is reset under the rebound effect of the spring 23.
Therefore, through this scheme of adoption, plate body 11 high position before can not be adjusted, can't realize the accurate regulation between plate body 11 and the depression bar 21, and then can realize this function now to can better exert the locking function of depression bar 21.
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 is simple in structure, and the height position of the locking pressing plate can be conveniently and accurately adjusted, so that the reliability of the safety locking device is effectively guaranteed.
