DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 3 A protection device for renovation of ancient buildings, comprising a base 1, a lifting plate 2 is mounted on the base 1 through a lifting mechanism, a mounting plate 4 is fixedly mounted on the lifting plate 2 through a supporting column 3, a lifting assembly comprises a second threaded rod 11 vertically rotatably mounted on the base 1 and a second adjusting block 12 fixedly mounted on the upper end of the second threaded rod 11, and the lifting plate 2 is threadedly sleeved on the second threaded rod 11;

[0023] When supporting and protecting ancient buildings, the device is placed directly below the ancient buildings, and then the second adjusting block 12 is rotated to drive the second threaded rod 11 to rotate, and the lifting plate 2 is limited by hand to rotate, thereby driving the lifting plate 2 to move vertically upward, and then the lifting plate 2 drives the mounting plate 4 to move toward the ancient building through the supporting column 3.

[0024] A limit hole is provided on the lifting plate 2, and a limit rod 13 is inserted into the limit hole. The limit rod 13 is vertically fixed on the base 1. When the lifting plate 2 is rotated and raised by the second threaded rod 11, the limit rod 13 can limit the rotation of the lifting plate 2.

[0025] The mounting plate 4 is provided with a plurality of threaded holes, each of which is threadedly inserted with a first threaded rod 5, a first adjusting block 10 is fixedly installed at the lower end of the first threaded rod 5, a mounting column 6 is installed at the upper end of the first threaded rod 5 through an elastic component, a spherical groove is provided at the upper end of the mounting column 6, a rolling ball 7 is rotatably embedded in the spherical groove, a cross plate 8 is fixedly installed on the rolling ball 7, a plurality of push rods 9 are fixedly installed on the cross plate 8, and the plurality of push rods 9 are arranged in a circle on the cross plate 8;

[0026] When the mounting plate 4 rises to a certain height, the first threaded rod 5 can be driven to rotate by rotating the first adjusting block 10, thereby driving the first threaded rod 5 to move vertically upward, and then the mounting column 6 can be driven to move vertically upward through the elastic component. During the movement, the multiple top rods 9 on the cross plate 8 will be driven to contact the bottom surface of the ancient building. In the process of contacting the ancient building, the multiple top rods 9 will drive the cross plate 8 and the ball 7 to rotate at the top of the mounting column 6 according to the arc shape of the bottom surface of the ancient building. The ball 7 rotates on the mounting column 6, and the inclination angle of the cross plate 8 can be adjusted so that the cross plate 8 is better opposite to the bottom surface of the ancient building, so that the multiple top rods 9 on the cross plate 8 are in contact with the bottom surface of the ancient building as much as possible, providing sufficient support area, thereby improving the stability of the support.

[0027] A moving groove is provided at the lower end of the mounting column 6, and the elastic component includes a telescopic spring 14 fixedly installed in the moving groove. The upper end of the first threaded rod 5 is inserted into the moving groove, and one end of the telescopic spring 14 is fixedly connected to the upper end of the first threaded rod 5. A strip hole connected to the moving groove is provided on the surface of the mounting column 6, and a rectangular block 15 is fixedly installed on the first threaded rod 5, and one end of the rectangular block 15 passes through the strip hole;

[0028] When multiple top rods 9 contact the bottom surface of the ancient building, the first threaded rod 5 will be inserted into the moving groove, the telescopic spring 14 will be compressed, and the elastic force of the telescopic spring 14 will generate a reaction force on the mounting column 6 and the cross plate 8, thereby supporting the ancient building through the reaction force. When the first threaded rod 5 moves relative to the mounting column 6, the rectangular block 15 will move in the strip hole, so that the compression amount of the telescopic spring 14 can be judged according to the distance moved by the rectangular block 15 in the strip hole, so that the compression of the telescopic spring 14 on multiple first threaded rods 5 is the same, so that the supporting force applied to multiple supporting points on the bottom surface of the ancient building is the same, avoiding damage to the ancient building due to different supporting forces.

[0029] A rolling groove is provided at the upper end of the top rod 9, in which a ball 16 is embedded for rolling. When the top rod 9 contacts and moves relative to the bottom surface of the ancient building, the ball 16 can reduce the friction between the two, thereby avoiding damage to the ancient building during the relative movement.

[0030] In the utility model, when the mounting plate 4 rises to a certain height, the first threaded rod 5 is rotated, thereby driving the first threaded rod 5 to move vertically upward. During the movement, the multiple top rods 9 on the cross plate 8 will be driven to contact the bottom surface of the ancient building. During the contact with the ancient building, the multiple top rods 9 will drive the cross plate 8 and the rolling ball 7 to rotate at the top of the mounting column 6 according to the arc shape of the bottom surface of the ancient building, so that the cross plate 8 is better relative to the bottom surface of the ancient building, so that the multiple top rods 9 on the cross plate 8 are in contact with the bottom surface of the ancient building as much as possible, providing sufficient support area, thereby improving the stability of the support.
