Description

Technical Field

[0001] This invention relates to the field of building equipment technology, and in particular to a construction equipment and method for curing adobe walls in classical dwellings. Background Technology

[0002] During the renovation and upgrading of old urban areas with ethnic characteristics, large areas of classical residences have been preserved near scenic tourist areas. These classical residences showcase local ethnic culture, customs, and lifestyles. In order to preserve the local ethnic characteristics and residential style, and to harmonize with the scenery of the scenic area, the exterior walls of the local residences are mostly made of adobe bricks. Due to long-term exposure to wind, sun, and rain, the soil in some of the adobe walls has been lost, and the loss is quite serious in some areas. Therefore, reinforcement is needed to preserve the original appearance of the residences while extending their durability and service life.

[0003] The existing repair of adobe walls in classical dwellings involves applying cement mortar or mud mixed with straw to the outer surface of the walls. However, this method often results in the added surface layer cracking, poor adhesion to the original base layer, and easy cracking and peeling after exposure to wind, sun, and rain. This affects the aesthetics, clashes with the style of the nearby scenic area, alters the original architectural style, and consumes a significant amount of manpower. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background art by proposing a construction equipment and method for curing adobe walls in classical dwellings.

[0005] On one hand, this application provides a construction device for curing adobe walls in classical dwellings, including a construction control component, which includes a driving base and further includes: Processing and transposition components used to adjust the construction range; The control drive assembly for construction includes an external protective box disposed on the surface of the driving base. A first motor is fixedly installed inside the external protective box. A worm gear is fixedly installed at the output end of the first motor passing through the external protective box. A hollow material transfer cylinder is fixedly installed inside the second gear. A corrugated transmission cylinder is slidably installed inside the hollow material transfer cylinder. An auxiliary sliding cavity rod is fixedly installed on one side of the corrugated transmission cylinder extending into the hollow material transfer cylinder. A second auxiliary gear and a first auxiliary gear are rotatably installed inside the external protective box via a rotating rod. The second auxiliary gear and the worm gear are meshed together. The corrugated transmission cylinder and the first auxiliary gear are meshed together. A paint storage tank is fixedly installed inside the construction control assembly. A flow pipe is rotatably installed inside the paint storage tank. A hollow material transfer cylinder is rotatably installed at one end of the flow pipe that extends into the interior of an external protective box.

[0006] Optionally, the construction control component also includes an external protective frame fixedly installed on the top of the driving base, and a manual control console is provided inside the driving base.

[0007] Optionally, the processing and repositioning assembly includes a fixed bracket fixedly installed on one side of the driving base, and an auxiliary sliding frame is slidably installed inside the fixed bracket via a hydraulic support rod.

[0008] Optionally, two sets of adjustable positioning plates are slidably installed inside the auxiliary sliding frame, and a bidirectional threaded rod is rotatably installed inside the auxiliary sliding frame. The threads at both ends of the bidirectional threaded rod are set in opposite states. The bidirectional threaded rod is threaded inside the adjustable positioning plate. A forward and reverse motor is fixedly installed on the outside of the auxiliary sliding frame, and one end of the bidirectional threaded rod passing through the auxiliary sliding frame is fixedly installed at the output end of the forward and reverse motor.

[0009] Optionally, the hollow conveyor cylinder has two hinged closed doors inside. A spring is fixedly installed at the connection between the closed door and the hollow conveyor cylinder. Under normal conditions, the two closed doors are set in a close-fitting state by relying on the restoring force of the spring.

[0010] Optionally, a second motor is fixedly installed inside the external protective box, and a first gear is fixedly installed on the output end of the second motor through the external protective box. A second gear is rotatably installed on the inner wall of the external protective box, and the second gear is meshed with the first gear.

[0011] Optionally, a processing component is installed on the side of the control drive assembly away from the construction control assembly. The processing component includes an adjustment drive box rotatably mounted on the surface of the external protective box. The adjustment drive box is fixedly mounted on one end of the hollow material transfer cylinder that passes through the external protective box. Two sets of clamping tools are rotatably mounted inside the adjustment drive box. A bidirectional threaded rod is rotatably mounted inside the adjustment drive box. The clamping tools are threaded onto the outside of the bidirectional threaded rod. A large-diameter hollow material transfer cylinder is fixedly mounted on the outside of the corrugated transmission cylinder. The diameter of the large-diameter hollow material transfer cylinder is larger than the diameter of the corrugated transmission cylinder. The large-diameter hollow material transfer cylinder is slidably mounted on the outside of the hollow material transfer cylinder. A driven gear is fixedly mounted in the middle of the bidirectional threaded rod. The driven gear is meshed with the large-diameter hollow material transfer cylinder.

[0012] On the other hand, this application provides a method for solidifying the adobe wall surface of classical dwellings, including the following steps: S1: Use equipment to clean up loose soil and impurities, and adjust the position by processing the transposition component. The hydraulic support rod drives the auxiliary sliding frame to move up and down to cover the entire wall surface. Use clamping tools to remove weeds and peeling parts of the wall surface. S2: Filling areas where soil has been lost or where the joints are not fully filled. The equipment injects slurry through a hollow conveyor cylinder, and the corrugated conveyor cylinder pushes the material under gear drive to ensure that the gaps are filled. S3: Switch the paint storage tank to the hardener. Drive the worm gear, first auxiliary gear and second auxiliary gear through the first motor to spray the hardener evenly on the wall surface to ensure uniform penetration of the hardener and enhance the adhesion of the base layer. S4: After the curing agent dries, the equipment adjusts the spraying angle through the second motor, the first gear and the second gear to ensure that the coating covers the wall surface completely; S5: After construction, use testing instruments to check the flatness of the wall surface, and use equipment to repair any defects in the wall surface.

[0013] Compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. As the auxiliary sliding rod moves forward, the closed door is pushed open, facilitating the release of mud, hardener, and waterproof coating. After the mud is used to repair the wall surface, the hardener is evenly sprayed onto the wall surface to ensure uniform penetration. After the hardener dries, two coats of transparent waterproof coating are applied to enhance the wall's resistance to weathering and waterproofing, while also maintaining the original style and appearance of the adobe wall, ensuring both aesthetics and durability. 2. The auxiliary motor drives the bidirectional threaded rod to rotate. Since the threads on both sides of the bidirectional threaded rod are opposite, the two sets of adjustable positioning plates connected to the bidirectional threaded rod move towards each other along the auxiliary sliding frame. Thus, the equipment can carry out construction in the horizontal direction. The hydraulic support rod drives the auxiliary sliding frame to move up and down along the fixed support, thus the equipment can carry out construction in the vertical direction, thereby improving the construction efficiency of the equipment for the adobe walls of classical dwellings. 3. The second motor drives the first gear to rotate. The first gear, through meshing with the second gear, drives the hollow material conveying cylinder to rotate along the flow pipe. The hollow material conveying cylinder then drives the adjustment drive box to rotate along the external protective box. The clamping tool can then clamp and rotate the weeds to pull them out, thereby achieving operational flexibility, saving a lot of manpower, and improving overall construction efficiency.

[0016] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0017] like Figures 1-3 As shown, the present invention proposes a construction equipment for curing adobe walls of classical dwellings, including a construction control component 1, which includes a driving base 101, a processing and positioning component 2 for adjusting the construction range, and a control drive component 3 for construction.

[0018] Furthermore, the construction control component 1 also includes an external protective frame 102 fixedly installed on the top of the driving base 101. A manual control console 103 is installed inside the driving base 101. The processing and positioning component 2 includes a fixed bracket 201 fixedly installed on one side of the driving base 101. An auxiliary sliding frame 202 is slidably installed inside the fixed bracket 201 via a hydraulic support rod. Two sets of adjustable positioning plates 203 are slidably installed inside the auxiliary sliding frame 202. A bidirectional threaded rod 204 is rotatably installed inside the auxiliary sliding frame 202, with the threads at both ends of the bidirectional threaded rod 204 arranged in opposite directions. The bidirectional threaded rod 204 is threaded inside the adjustable positioning plates 203. A forward and reverse motor is fixedly installed on the outside of the auxiliary sliding frame 202. One end of the bidirectional threaded rod 204, passing through the auxiliary sliding frame 202, is fixedly installed at the output end of the forward and reverse motor. The worker sits in the parking space attached to the driving base 101. The entire equipment is operated remotely via a manual control console 103. The traveling base 101 travels to the adobe wall of the classical dwelling that needs to be constructed using its attached wheels. Since there are many damaged areas on the surface of the adobe wall, it is necessary to thoroughly clean the adobe wall first to remove loose soil and impurities. Then, the soil loss and damage of the adobe wall are repaired, and the gaps in the adobe joints are filled and compacted. The auxiliary motor drives the bidirectional threaded rod 204 to rotate. Since the threads on both sides of the bidirectional threaded rod 204 are opposite, the two sets of adjustable positioning plates 203 connected to the bidirectional threaded rod 204 move towards each other along the auxiliary sliding frame 202, so that the equipment can carry out construction in the horizontal direction. The hydraulic support rod drives the auxiliary sliding frame 202 to move up and down along the fixed support 201, so that the equipment can carry out construction in the vertical direction, thereby improving the construction efficiency of the equipment for the adobe wall of the classical dwelling.

[0019] like Figures 4-8 As shown, the control drive assembly 3 includes an external protective box 301 disposed on the surface of the driving base 101. A first motor 304 is fixedly installed inside the external protective box 301. A worm gear 308 is fixedly installed through the output end of the first motor 304. A hollow material transfer cylinder 302 is fixedly installed inside the second gear 307. A corrugated transmission cylinder 303 is slidably installed inside the hollow material transfer cylinder 302. An auxiliary sliding cavity rod 312 is fixedly installed on one side of the corrugated transmission cylinder 303 extending into the hollow material transfer cylinder 302. A second auxiliary gear 311 and a first auxiliary gear 310 are rotatably installed inside the external protective box 301 via a rotating rod. The second auxiliary gear 311 is meshed with the worm gear 308, and the corrugated transmission cylinder 303 is meshed with the first auxiliary gear 310. A paint storage tank 5 is fixedly installed inside the construction control component 1. A flow pipe is rotatably installed inside the paint storage tank 5. A hollow material transfer cylinder 302 is rotatably installed at one end of the flow pipe that extends into the outer protective box 301. Two closing doors 309 are hinged inside the hollow material transfer cylinder 302. A spring is fixedly installed at the connection between the closing door 309 and the hollow material transfer cylinder 302. Under normal conditions, the two closing doors 309 are set in a close-fitting state by relying on the restoring force of the spring.

[0020] In this embodiment, the conventional method for treating the adobe walls of classical dwellings is to apply cement mortar or mud mixed with straw to the outer surface of the adobe walls. However, this method often results in the added surface layer cracking, poor adhesion to the original base layer, and easy cracking and peeling after exposure to wind, sun, and rain, affecting the aesthetics, clashing with the style of the nearby scenic area, and altering the original architectural style. In contrast, the paint storage tank 5 of this device can hold mud, hardener, and waterproof coating. The first motor 304 drives the worm gear... When rod 308 rotates, the worm gear 308 meshes with the second auxiliary gear 311, causing the second auxiliary gear 311 to rotate. The second auxiliary gear 311 then drives the first auxiliary gear 310 to rotate synchronously via a rotating rod. The teeth of the first auxiliary gear 310 are engaged in the concave and convex surfaces of the corrugated conveyor cylinder 303. Therefore, when the first auxiliary gear 310 rotates, its teeth exert a thrust on the concave and convex surfaces of the corrugated conveyor cylinder 303, causing the corrugated conveyor cylinder 303 to slide along the hollow conveyor cylinder 302. The auxiliary sliding rod 312 slides along the hollow transfer cylinder 302. Because the mud, hardener, and waterproof coating have a certain viscosity and solidify after losing moisture, the sliding of the auxiliary sliding rod 312 agitates the mud, hardener, and waterproof coating, allowing them to detach after curing. This improves the efficiency of their use. Simultaneously, the closed door 309 normally blocks the injection port of the hollow transfer cylinder 302, preventing air circulation and slowing down the mixing of the mud, hardener, and waterproof coating. The coating cures within the hollow transfer cylinder 302, preventing dirt from contaminating the slurry, hardener, and waterproof coating. As the auxiliary sliding rod 312 moves forward, the closing door 309 is pushed open, facilitating the release of the slurry, hardener, and waterproof coating. After the slurry is applied to the wall surface, the hardener is sprayed evenly to ensure uniform penetration. After the hardener dries, two coats of transparent waterproof coating are applied to enhance the wall's weather resistance and waterproof performance, while also maintaining the original style and appearance of the adobe wall, ensuring both aesthetics and durability.

[0021] like Figures 4-8As shown, a second motor 305 is fixedly installed inside the external protective box 301. A first gear 306 is fixedly installed on the output end of the second motor 305 through the external protective box 301. A second gear 307 is rotatably installed on the inner wall of the external protective box 301. The second gear 307 is meshed with the first gear 306. A processing component 4 is installed on the side of the control drive component 3 away from the construction control component 1. The processing component 4 includes an adjustment drive box 401 rotatably installed on the surface of the external protective box 301. The adjustment drive box 401 is fixedly installed on one end of the hollow material transfer cylinder 302 that passes through the external protective box 301. Two sets of clamping tools 402 are rotatably installed inside the moving box 401. A bidirectional threaded rod 403 is rotatably installed inside the adjusting drive box 401. The clamping tools 402 are threadedly installed on the outside of the bidirectional threaded rod 403. A large-diameter hollow material transfer cylinder 404 is fixedly installed on the outside of the corrugated transmission cylinder 303. The diameter of the large-diameter hollow material transfer cylinder 404 is larger than the diameter of the corrugated transmission cylinder 303. The large-diameter hollow material transfer cylinder 404 is slidably installed on the outside of the hollow material transfer cylinder 302. A driven gear 405 is fixedly installed in the middle of the bidirectional threaded rod 403. The driven gear 405 is meshed with the large-diameter hollow material transfer cylinder 404.

[0022] In this embodiment, some damaged areas in the soil may contain weeds, and in areas with large-area damage, the weeds need to be removed. The soil around the large damaged areas of the adobe walls of the classical dwelling also needs to be removed and repaired. When the worm gear 308 rotates in the reverse direction, the corrugated transmission cylinder 303 moves towards the first motor 304. Since the diameter of the large-diameter hollow transfer cylinder 404 is larger than the diameter of the hollow transfer cylinder 302, the large-diameter hollow transfer cylinder 404 is limited by the external protective box 301. Within the specified range, the large-diameter hollow transfer cylinder 404 drives the bidirectional threaded rod 403 to rotate through meshing with the driven gear 405. The bidirectional threaded rod 403 uses thread transmission to cause the clamping tool to rotate. 402 moves along the adjustment drive box 401 towards the direction of clamping weeds. It should be noted that the clamping tool 402 is used to clamp weeds. For other tools, such as scrapers, the clamping tool 402 can be disassembled for installation. The second motor 305 drives the first gear 306 to rotate. The first gear 306, through meshing with the second gear 307, drives the hollow material conveying cylinder 302 to rotate along the flow pipe. The hollow material conveying cylinder 302 then drives the adjustment drive box 401 to rotate along the outer protective box 301. The clamping tool 402 can then clamp the weeds and rotate them out, thereby achieving operational flexibility, saving a lot of manpower, and improving the overall construction efficiency.

[0023] On the other hand, this application provides: a method for solidifying the adobe wall surface of classical dwellings, including the following steps: S1: Use equipment to clean up loose soil and impurities, and adjust the position by processing the transposition component 2. The hydraulic support rod drives the auxiliary sliding frame 202 to move up and down to cover the entire wall surface. Use the clamping tool 402 to remove weeds and peeling parts of the wall surface. S2: Fill the areas where soil has been lost or where the joints are not fully filled. The equipment injects mud through the hollow material conveyor 302 and the corrugated conveyor 303 pushes the material under gear drive to ensure that the gaps are filled. S3: Switch the paint storage tank 5 to the hardener, and drive the worm gear 308, the first auxiliary gear 310 and the second auxiliary gear 311 through the first motor 304 to spray the hardener evenly on the wall surface to ensure uniform penetration of the hardener and enhance the adhesion of the base layer; S4: After the curing agent dries, the equipment adjusts the spraying angle through the second motor 305, the first gear 306 and the second gear 307 to ensure that the coating covers the wall surface completely. S5: After construction, use testing instruments to check the flatness of the wall surface, and use equipment to repair any defects in the wall surface.

[0024] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
