Description

Technical Field

[0001] This utility model relates to the field of ancient building restoration and protection technology, and in particular to a support device for restoration and protection. Background Technology

[0002] Ancient buildings are precious cultural treasures left to us by our ancestors. They have value in many aspects, including history, culture, science and technology, and art. A well-preserved ancient building is not only an important material for studying the history and culture of a certain period, but also a historical witness to social and cultural changes.

[0003] A search revealed that the document with announcement number "CN222435972U" mentions "a support device for the restoration and protection of ancient buildings, including a base plate, two lifting sleeves rotatably connected to both sides of the top surface of the base plate, lifting telescopic columns threadedly connected to the inner walls of the four lifting sleeves, a lifting top plate fixedly connected to the top of the four lifting telescopic columns, and a plurality of threaded sleeves rotatably connected to both sides of the top surface of the lifting top plate, with lifting threaded columns threadedly connected to the inner walls of the plurality of threaded sleeves." By rotating the first worm gear, two adjacent first worm wheels can be simultaneously driven to rotate, which in turn drives two adjacent threaded sleeves to rotate, thereby driving the two lifting threaded columns at the bottom of the same support plate to rise and fall synchronously. This allows for the adjustment of the height of several support plates, making the support surface composed of several support plates adapt to the undulations of the ancient building's support surface, thereby improving the fit and stability of the support, and demonstrating high practicality.

[0004] However, the existing support devices rely heavily on manual adjustment of the lifting height, which is not only inconvenient to operate but also labor-intensive for operators. Furthermore, the device is prone to slippage during the support process due to the force applied by the wheels, which can cause the support position to shift and affect the restoration and protection of ancient buildings.

[0005] Therefore, we provide a support device for the restoration and protection of ancient buildings to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 As shown, this utility model provides a technical solution: a support device for the restoration and protection of ancient buildings, including a support platform 1, an extension / retraction component 2 disposed on the inner side of the support platform 1, and a support component 3 connected to the outer perimeter of the upper side of the support platform 1. The support component 3 includes a support base 301 fixedly connected to the upper side of the support platform 1, a rotating shaft 302 installed at the center of the inner side of the support base 301, a large gear 303 connected to the lower side of the rotating shaft 302, a small gear 304 meshing with the outer side of the large gear 303, and a motor connected to the outer side of the small gear 304. 305, a nut sleeve 306 is threadedly connected to the upper side of the rotating shaft 302, a lifting shaft 307 is bolted to the upper side of the nut sleeve 306, an outer support assembly 4 is installed on the upper side of the lifting shaft 307, the outer support assembly 4 includes an outer support frame 401 connected to the outside of the support base 301, a guide sleeve 402 is provided at the upper center position of the outer support frame 401, a support shaft 403 is installed on the inner side of the guide sleeve 402, a clamping sleeve 404 is installed on both the upper and lower sides of the support shaft 403, and a bolt 405 is connected to the outer side of the clamping sleeve 404.

[0033] Furthermore, the retraction and extension assembly 2 includes a cylinder 201 fixedly connected to the upper part of the support platform 1. A longitudinal rod 202 is connected to the lower side of the cylinder 201, and a crossbar 203 is welded to the lower side of the longitudinal rod 202. A connecting rod 204 is connected to the outer side of the crossbar 203, and a wheel seat 205 is connected to the end of the connecting rod 204. A wheel 206 is installed on the inner side of the wheel seat 205. A rotating shaft bracket 207 is fixedly connected to the four corners of the lower part of the support platform 1. The cylinder 201 drives the longitudinal rod 202 and the crossbar 203 to move vertically up and down together. The crossbar 203 as a whole drives the connecting rod 204, the wheel seat 205, and the wheel 206 to complete the retraction and extension movement together through the rotating shaft bracket 207, so as to achieve the purpose of flexible and fast overall retraction and extension of the wheel 206 and the wheel seat 205, saving the operator's time and thus improving work efficiency.

[0034] Furthermore, the crossbar 203 and the connecting rod 204 are rotatably connected, and the connecting rod 204 and the wheel seat 205 are also rotatably connected. The connecting rod 204 and the wheel seat 205 form a rotating structure through the rotating shaft bracket 207, thereby achieving the purpose of retracting and extending the wheel 206 and the wheel seat 205. During the support process of repair and protection, the cylinder 201 drives the longitudinal rod 202 and the crossbar 203 to move vertically upward together. The crossbar 203 drives the connecting rod 204 to move upward. The connecting rod 204 drives the wheel seat 205 and the wheel 206 to rotate upward together through the rotating shaft bracket 207. The wheel seat 205 and the wheel 206 are retracted into the interior of the support platform 1, so that the bottom of the support platform 1 directly bears the working force, making it more stable and preventing it from shifting or shaking during operation. At the same time, it improves the stability and service life of the device. After the repair and protection is completed, the wheel 206 is released to the outside of the support platform 1 to ensure that the whole is movable.

[0035] Furthermore, the motor 305 is coaxially connected to the pinion 304, the pinion 304 is meshed with the large gear 303, and the large gear 303 is coaxially connected to the rotating shaft 302. The motor 305 is fixed on the support base 301, and the rotating shaft 302 forms a rotating structure through the large gear 303 and the pinion 304. In use, the motor 305 drives the pinion 304, which in turn drives the large gear 303, thereby amplifying the working torque of the large gear 303, increasing the lifting force at the support end, and improving the support effect on the ancient building.

[0036] Furthermore, the rotating shaft 302 and the nut sleeve 306 are threadedly connected, and the nut sleeve 306 and the lifting shaft 307 are coaxially connected. A guide key is slidably connected to the side end of the lifting shaft 307. The nut sleeve 306 and the lifting shaft 307 form a lifting structure through the rotating shaft 302. The rotating shaft 302 causes the nut sleeve 306 to move up and down through threaded transmission, which in turn causes the nut sleeve 306 to drive the lifting shaft 307 to move vertically up and down. Then, the lifting shaft 307 drives the support shaft 403 to move vertically up and down. The vertical movement of the support shaft 403 lifts the support device to the repair area of ​​the ancient building. At the same time, the guide key limits the lifting shaft 307 to prevent it from rotating, ensuring the stability and accuracy of the support process.

[0037] Furthermore, there are two sets of clamping sleeves 404 and bolts 405. The clamping sleeve 404 is fixed to the surface of the upper and lower ends of the support shaft 403 by the bolts 405. The clamping sleeve 404 plays a limiting and protective role, preventing the support shaft 403 from accidentally falling off during the support lifting process, thus protecting the personal safety of the operators. A guide sleeve is provided on the inner side of the outer support frame 401 to ensure the accurate positioning of the support shaft 403 and prevent the support shaft 403 from shifting.

[0038] Furthermore, the upper side of the lifting shaft 307 is threadedly connected to the support shaft 403, and the upper side of the support shaft 403 is welded to the support plate 406. The top of the support plate 406 is bonded with a rubber pad 407. The support plate 406 can stably support the supported object, and the rubber pad 407 can absorb the impact force during the lifting and repair protection process, protecting the ancient building materials from damage.

[0039] Working principle: Move the device to the working position, then the cylinder 201 drives the longitudinal rod 202 and the transverse rod 203 to move vertically up and down together. The transverse rod 203 drives the connecting rod 204 to rotate by an angle. The connecting rod 204 drives the wheel 206 and wheel seat 205 to rotate by an angle through the rotating shaft bracket 207, so that the wheel 206 and wheel seat 205 are put into the support platform (1) to ensure the stability of the support device. Then start the motor 305. The motor 305 drives the small gear 304 to rotate. The small gear 304 drives the rotating shaft 302 to rotate through the large gear 303. The rotating shaft 302 drives the nut sleeve 306 to move up and down through the threaded transmission. The nut sleeve 306 drives the lifting shaft 307 to move vertically up and down. Then the lifting shaft 307 drives the support shaft 403 to move vertically up and down. The support shaft 403 moves vertically up and down, thereby lifting the support device to the repair area of ​​the ancient building. Subsequently, the clamping sleeve 404 limits and protects the support shaft 403 during its lifting and lowering movement, preventing it from accidentally falling off during the lifting process. At the same time, a guide sleeve is provided on the inner side of the outer support frame 401 to ensure accurate positioning of the support shaft 403 and prevent it from shifting. During the support process of the ancient building, the rubber pad 407 can absorb the impact force during the lifting and repair process, protecting the ancient building materials from damage. After the repair is completed, the wheel 206 is extended to the outside of the support platform 1, making the whole device movable. This completes the use process of a support device for the repair and protection of ancient buildings.
