Description

Technical Field

[0001] The utility model relates to a top supporting device for reinforcing murals and colored sculptures, in particular to a telescopic top supporting device for reinforcing murals and colored sculptures. Background Art

[0002] Murals and colored sculptures are important components of cultural heritage. They carry rich historical connotations and are historical witnesses of the aesthetic paradigms and value concepts of a country and nation in different historical periods and regions. Due to their age, as well as the influence of natural environment and human factors, many murals and colored sculptures have suffered from warping, cracking and other defects, requiring reinforcement and restoration. During the restoration process, since the curing of the reinforcing agent takes a certain amount of time, the staff usually use a top support device to support the murals and colored sculptures to ensure the overall stability of the cultural relics.

[0003] The traditional supporting device is relatively simple, generally consisting of interconnected support rods and support plates. One end of the support rod is placed on the ground or on an aerial work bracket, and the support plate is in contact with the murals and colored sculptures to achieve the supporting function. This traditional supporting device has the problem that the length of the support rod cannot be adjusted, and the support plate may damage the cultural relics because of its too hard texture. Moreover, it is not suitable for local support of uneven murals and colored sculptures. Utility Model Content

[0004] The purpose of the utility model is to provide a retractable top supporting device with adjustable length for reinforcing murals and colored sculptures in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A retractable support device for reinforcing murals and colored sculptures, comprising a fixed cylinder, a rotating cylinder, a support rod and a rubber pad, wherein the first end of the two ends of the fixed cylinder is open, and a circular ring groove is provided on the circumferential outer wall of the fixed cylinder close to the first end, and both ends of the rotating cylinder are open and the circumferential inner wall of the first end protrudes toward the center line thereof to form a convex ring, the first end of the fixed cylinder is placed in the rotating cylinder and the convex ring is placed in the circular ring groove, the first end of the two ends of the support rod is placed in the inner hole of the fixed cylinder, and the support rod passes through the first end of the fixed cylinder and the inner wall of the rotating cylinder. A central through hole, the rubber pad is installed at the second end of the support rod, the circumferential hole wall near the second end of the central through hole of the rotating cylinder is provided with an internal thread, the circumferential outer wall of the support rod is provided with an external thread and is connected with the internal thread of the rotating cylinder, and a strip limiting groove is provided on the circumferential inner wall near the second end of the fixed cylinder, the length direction of the strip limiting groove is the same as the length direction of the support rod, and an outwardly convex strip limiting portion is provided on the support rod near its first end, and the strip limiting portion is placed in the strip limiting groove and can be limited and moved in the length direction of the strip limiting groove.

[0007] Preferably, in order to facilitate driving the rotating cylinder to rotate and to maintain a relatively stable state after stopping rotation, the middle portion of the outer wall of the rotating cylinder is rotatably connected to the first end of the rotating handle, and the second end of the rotating handle is connected to an open clamping ring for clamping with the outer wall of the fixed cylinder.

[0008] Preferably, in order to facilitate installation of the device on the support pipe for easy application, the second end of the fixed cylinder is rotatably connected with a clamp for connecting to the support pipe.

[0009] Preferably, in order to prevent the soft rubber pad from adhering to the surface of the cultural relic, the rubber pad is coated with tin foil.

[0010] Preferably, in order to facilitate processing and assembly, the fixed cylinder and the rotating cylinder are both formed by two semi-cylinders with semicircular cross-sections connected to each other.

[0011] The beneficial effects of the utility model are:

[0012] The utility model designs a fixed cylinder, a rotating cylinder and a supporting rod that cooperate with each other, so that the supporting rod can only move axially relative to the fixed cylinder but cannot rotate, and the rotating cylinder can only rotate relative to the fixed cylinder but cannot move axially. When the rotating cylinder is driven to rotate, the supporting rod can move axially therefrom, thereby changing the length of the device, realizing the reliable supporting function of murals and colored sculptures, and avoiding damage to cultural relics by installing rubber pads. The utility model is particularly suitable for local support of uneven murals and colored sculptures, and can also be used for grouting reinforcement support of hollow stone cultural relics.

[0014] The utility model is further described below in conjunction with the accompanying drawings:

[0015] like Figure 1 As shown, the retractable support device for reinforcing murals and colored sculptures of the utility model comprises a fixed cylinder 3, a rotating cylinder 12, a support rod 6 and a rubber pad 14. The first end of the two ends of the fixed cylinder 3 is open, and the circumferential outer wall of the fixed cylinder 3 close to the first end is provided with an annular groove 8. Both ends of the rotating cylinder 12 are open and the circumferential inner wall of the first end protrudes toward the center line thereof to form a convex ring 9. The first end of the fixed cylinder 3 is placed in the rotating cylinder 12 and the convex ring 9 is placed in the annular groove 8. The first end of the two ends of the support rod 6 is placed in the inner hole 2 of the fixed cylinder 3. The support rod 6 passes through the first end of the fixed cylinder 3 and the central through hole of the rotating cylinder 12. The rubber pad 14 is provided with a rubber pad 14. 4 is installed at the second end of the two ends of the supporting rod 6, the circumferential hole wall near the second end of the central through hole of the rotating cylinder 12 is provided with an internal thread 13, the circumferential outer wall of the supporting rod 6 is provided with an external thread 7 (a section of the circumferential outer wall of the supporting rod 6 near the first end thereof has the external thread 7) and is connected with the internal thread 13 of the rotating cylinder 12, and a strip-shaped limiting groove 5 is provided on the circumferential inner wall near the second end of the two ends of the fixed cylinder 3, and the length direction of the strip-shaped limiting groove 5 is the same as the length direction of the supporting rod 6, and a convex strip-shaped limiting portion 4 is provided on the supporting rod 6 near the first end thereof, and the strip-shaped limiting portion 4 is placed in the strip-shaped limiting groove 5 and can be limited and moved in the length direction of the strip-shaped limiting groove 5.

[0016] like Figure 1 As shown, the utility model also discloses the following more optimized specific structures:

[0017] In order to facilitate the driving of the rotating cylinder 12 to rotate and to enable it to maintain a relatively stable state after stopping rotation, the middle part of the outer wall of the rotating cylinder 12 is rotatably connected to the first end of the rotating handle 11 through a hinge, and the second end of the rotating handle 11 is connected to an open clamping ring 10 for clamping with the outer wall of the fixed cylinder 3.

[0018] In order to facilitate installation of the device on a support pipe (not shown in the figure) for easy application, the second end of the fixed cylinder 3 is rotatably connected to a clamp 1 for connecting with the support pipe through a hinge.
