DETAILED DESCRIPTION

[0024] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples.

[0025] This embodiment provides a single-layer steel wire rope isolator, the structure of which is as follows: Figure 1 and 2 As shown, it mainly includes a base 1, a top plate 2, a steel wire rope 4, a cover plate 5, a clamping plate 8, a limit assembly 9 and a support assembly 10.

[0026] A top plate 2 is arranged above the base 1, and a plurality of corresponding through wire rope grooves 3 are processed on the side walls of the base 1 and the top plate 2, and a plurality of wire ropes 4 arranged side by side pass through the wire rope grooves 3 on the base 1 and the top plate 2 in a circumferential form. The cover plate 5 is installed on the top of the top plate 2 by bolts 6, and the upper section of the wire rope 4 is pressed tightly in the wire rope groove 3 on the top plate 2. Through slots 7 are processed on both sides of the inner wall of each wire rope groove 3 on the base 1, and a movable card plate 8 is inserted into the interior of each card groove 7, and a limiting assembly 9 for fixing the card plate 8 and the card groove 7 is installed inside the card plate 8, and the lower section of the wire rope 4 is pressed tightly in the wire rope groove 3 on the base 1 through the card plate 8. A support assembly 10 is arranged between the base 1 and the top plate 2.

[0027] When working, it is supported by the top plate 2 and cushioned and seismically isolated by the steel wire rope 4. The limit assembly 9 can be used to facilitate the removal of the card plate 8 from the inside of the card slot 7, which facilitates the replacement of the steel wire rope 4. The support assembly 10 can increase the support effect of the device.

[0028] like Figure 3 As shown, the limit assembly 9 includes a rotating shaft rod 901, a connecting rope 902, a clamping rod 904 and a mounting spring 905. The rotating shaft rod 901 is inserted into the interior of the clamping plate 8 by the outer end surface of the clamping plate 8 in a rotating connection manner. Two movable grooves 903 are symmetrically processed on both sides of the rotating shaft rod 901 on the clamping plate 8. The interior of the clamping groove 7 is processed with a mounting groove 15 corresponding to and connected to the two movable grooves 903. Two clamping rods 904 are respectively arranged in the interior of the corresponding movable grooves 903 in a sliding connection manner, and the outer ends of the clamping rods 904 extend into the corresponding mounting grooves 15. The inner end of each clamping rod 904 is fixedly connected to the outer wall of the rotating shaft rod 901 through the connecting rope 902. A mounting spring 905 is arranged at the bottom of each movable groove 903, and the outer end of the mounting spring 905 contacts the inner end of the clamping rod 904. A magnetic block 11 is fixedly connected to the interior of the mounting groove 15, and the magnetic block 11 can adsorb the clamping rod 904, so that it is more secure during installation. The movable groove 903 is provided with a connected limit groove 12 inside, and the outside of the clamping rod 904 is fixedly connected with a slide plate 13, which is slidably connected inside the limit groove 12, so that the clamping rod 904 is more stable when moving and cannot rotate. The outer end of the rotating shaft rod 901 extends to the outside of the clamping plate 8, and the outer end of the rotating shaft rod 901 is processed with a wrench groove 14, which is convenient for using a wrench to rotate the rotating shaft rod 901.

[0029] During operation, the shaft rod 901 is rotated, and the shaft rod 901 drives the connecting rope 902 to be wound around the shaft rod 901, thereby pulling the clamping rod 904, and pulling the clamping rod 904 out of the installation slot 15, so that the clamping plate 8 loses the limit of the limit assembly 9. After the clamping plate 8 is taken out from the inside of the clamping slot 7, the lower section of the wire rope 4 can be removed. The top plate 2 can also be provided with the same structure as the base 1 and use the limit assembly 9, so that each wire rope 4 can be removed independently for targeted replacement.

[0030] like Figure 4 As shown, the support assembly 10 includes a sliding frame 1002, a connecting rod 1003, a support plate 1004, a first damping spring 1005 and a second damping spring 1006. Among them, two slide grooves 1001 are symmetrically processed on the top of the base 1, and the two sliding frames 1002 are respectively slidably connected inside the corresponding slide grooves 1001, and the two first damping springs 1005 are respectively fixedly connected to the outside of the corresponding sliding frame 1002 and fixedly connected inside the slide groove 1001. The lower ends of the two connecting rods 1003 are respectively hinged to the top of the corresponding sliding frame 1002, and the upper ends of the two connecting rods 1003 are symmetrically hinged to both sides of the support plate 1004. A second damping spring 1006 is fixedly connected between the base 1 and the support plate 1004 to further increase the seismic isolation effect.

[0031] During operation, the top plate 2 is supported by the support plate 1004, and the first damping spring 1005 elastically supports the sliding frame 1002. The force exerted on the support plate 1004 can be transmitted to the sliding frame 1002 by the connecting rod 1003, and then buffered and isolated by the first damping spring 1005, so that vertical support can be performed to increase the isolation effect.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
