Detailed Implementation

[0029] The technical solutions of the present invention will now be described with reference to the accompanying drawings in the embodiments of the present invention.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] The following description, with reference to the accompanying drawings, describes a conversion device for road surface removal according to an embodiment of the present invention.

[0032] Please see Figures 1 to 10According to an embodiment of the present invention, a road surface retraction conversion device includes: a retraction drum support assembly 100, a conversion container assembly 200, a guide container assembly 300, and a container road surface module 400.

[0033] Please see Figure 1 A folded road surface is wound on the retraction drum support assembly 100. The conversion container assembly 200 is located behind the retraction drum support assembly 100. The conversion container assembly 200 guides the pin of the folded road surface to slide down. The lower end of the folded road surface is folded under the action of gravity. The guide container assembly 300 is connected to the rear side of the conversion container assembly 200. The container road surface module 400 is connected to the rear side of the guide container assembly 300. The road surface folded by the conversion container assembly 200 is guided into the container road surface module 400 by the guide container assembly 300 under the action of gravity. The retraction drum support assembly 100 releases the folded pavement, and pulls the end of the folded pavement into the conversion container assembly 200. The conversion container assembly 200 moves the pins of the folded pavement in sequence. The pavement panels without pins in the folded pavement fold under the action of gravity. As the retraction drum support assembly 100 continuously releases the folded pavement, the folded pavement folds in sequence. The folded pavement panels are guided by the guide container assembly 300 into the container pavement module 400 for storage. The folded pavement on the front side pushes the folded pavement on the rear side by gravity until the container pavement module 400 is full. This achieves the purpose of transferring the recovered folded pavement into the container pavement module 400 for the next operation.

[0034] Please see Figures 1 to 2 The retraction drum support assembly 100 includes a first pallet platform 110, a connecting platform 120, and a retraction drum support 130. The connecting platform 120 is disposed on the first pallet platform 110, and four connecting bases on the lower side of the retraction drum support 130 are inserted into the connecting platform 120 via pins. The first pallet platform 110 can move in a directional manner along a preset track on the gantry bridge. The connecting platform 120 is used to support the retraction drum support 130. The retraction drum support 130 retracts the folded road surface. After the retraction drum support 130 retracts the folded road surface, it is installed on the connecting platform 120, and the folded road surface is released through the retraction drum support 130.

[0035] Please see Figures 1 to 3The connecting platform 120 includes a support frame 121, an extension frame 122, a connecting seat 123, a top-tightening mounting bracket 124, and a top-tightening component 125. The extension frame 122 is fixedly connected to the support frame 121, and the connecting seat 123 is fixedly connected to both ends of the extension frame 122. The connecting base on the lower side of the retractable drum bracket 130 is inserted into the connecting seat 123 through a pin. The top-tightening mounting bracket 124 is fixedly connected to the four corners on the upper side of the support frame 121, and the top-tightening component 125 is installed on the top of the top-tightening mounting bracket 124. The top-tightening component 125 can hold the four corners on the lower side of the retractable drum bracket 130. The support frame 121 supports the retraction drum bracket 130 with a folded road surface. The connecting base on the lower side of the retraction drum bracket 130 is connected to the connecting seat 123 by a pin, thus completing the connection of the retraction drum bracket 130. After the retraction drum bracket 130 is installed, the tightening member 125 is raised to hold the four corners on the lower side of the retraction drum bracket 130. By pulling out the pin, the retraction drum bracket 130 can be lifted for replacement.

[0036] Please see Figures 1 to 4The container conversion assembly 200 includes a second pallet platform 210, a heightening base 220, a container conversion rack 230, a front mounting beam 240, a lower guide wheel assembly 250, guide rollers 260, a drive shaft 270, a chain pusher 280, and a first lower slide rail 290. The heightening base 220 is fixedly connected to the four corners of the upper side of the second pallet platform 210. The four corners of the lower side of the container conversion rack 230 are connected to the heightening base 220. The front mounting beam 240 is fixedly connected to the left and right ends of the front interior of the container conversion rack 230. The lower guide wheel assemblies 250 are symmetrically installed at both ends of the front mounting beam 240, and the rear ends of the lower guide wheel assemblies 250 are tilted. The guide roller 260 is positioned diagonally upwards on the upper side of the front mounting beam 240. The drive shaft 270 is laterally positioned at the left and right ends of the front side of the conversion container frame 230. Two chain pushers 280 are provided, which are respectively positioned at the left and right ends inside the conversion container frame 230. The chain pushers 280 are inclined upwards from the rear end to the front end. The drive shaft 270 drives the front end of the chain pushers 280. The first lower slide rail 290 is fixedly connected to the inner wall of the chain pusher 280. The first lower slide rail 290 is inclined along the direction of the chain pusher 280 and is located between the upper and lower sides of the chain pusher 280. The folded road surface released by the retractable drum support assembly 100 is guided to the chain pusher 280 via the sliding guide wheel 250 and guide roller 260. The drive shaft 270 drives the chain pusher 280 to rotate, which in turn drives the hook of the folded road surface, actively pushing the road panel of the folded road surface backward. The road panel at the free end below the hook automatically folds under the action of gravity. When the sliding resistance of the road panel is large during the retraction, the chain pusher 280 plays an auxiliary pushing role. When the sliding of the road panel is inconsistent, the chain pusher 280 can play a limiting role, so that the road panel slides down in an orderly manner and does not slip and break out of the first sliding rail 290.

[0037] Please see Figures 1 to 5 The drive shaft component 270 includes a drive motor 271, a mounting base 272, a transmission shaft 273, and a drive sprocket 274. The drive motor 271 is fixedly connected to one end of the front side of the conversion container frame 230. The mounting base 272 is fixedly connected to the interior of the front end of the chain pusher 280. One side of the drive sprocket 274 is rotatably connected to the lower side of the front end of the mounting base 272. The transmission shaft 273 is fixedly connected to the output end of the drive motor 271 and rotatably passes through the drive sprocket 274. The drive sprocket 274 drives the lower side of the front end of the chain pusher 280. The drive motor 271 drives the transmission shaft 273, which in turn drives the drive sprocket 274 to rotate on the mounting base 272. The drive sprocket 274 drives the chain pusher 280 to rotate via chain drive.

[0038] Please see Figures 1 to 7The chain drive component 280 includes an inclined mounting frame 281, a front follower sprocket 282, a rear follower sprocket 283, a chain 284, a deflector plate 285, and a chain guide groove 286. The inclined mounting frame 281 connects to the left and right ends inside the container frame 230. The mounting base 272 is fixedly connected to the front end of the inclined mounting frame 281. One side of the front follower sprocket 282 is rotatably connected to the upper side of the rear end of the mounting base 272, and the rear follower sprocket 283 is rotatably connected to the rear end of the inclined mounting frame 281. The chain 284 follows... The secondary transmission is connected to the drive sprocket 274, the front follower sprocket 282, and the rear follower sprocket 283. The deflector plate 285 is disposed on the inner chain plate inside the chain 284. The chain guide groove 286 is fixedly connected to the upper side of the inclined mounting frame 281. The upper side of the chain 284 is located inside the chain guide groove 286. The chain 284 is conveyed along the chain guide groove 286. The first lower slide rail 290 is fixedly connected to the inner side of the inclined mounting frame 281. The first lower slide rail 290 is located below the deflector plate 285 on the upper side of the chain 284. The drive motor 271 drives the transmission shaft 273, which in turn drives the drive sprocket 274 to rotate on the mounting base 272. The drive sprocket 274 drives the chain 284 to rotate. The front follower sprocket 282 and the rear follower sprocket 283 rotate with the chain 284. The chain 284 is limited by a dedicated chain guide groove 286. When the chain 284 is rotating, the lever 285 can actively push the folded road panel backward through the hanging pin. When the road panel retraction and transition to sliding resistance is large, the lever 285 can play an auxiliary pushing role. When the road panel slides unevenly, the lever 285 can play a limiting role, so that the road panel slides down in an orderly manner and does not slip and break out of the first sliding rail 290.

[0039] Please see Figures 1 to 8 The sliding guide wheel component 250 includes a downward tilting mounting frame 251, a top guide wheel 252, a guide frame 253, and pulleys 254. The lower end of the downward tilting mounting frame 251 is fixedly connected to the front mounting beam 240. The top guide wheel 252 is located at the top of the upper end of the downward tilting mounting frame 251. The guide frame 253 is mounted on the upper side of the downward tilting mounting frame 251, and the pulleys 254 are evenly spaced on the guide frame 253. The top guide wheel 252 guides the road panel, reducing the possibility of the road panel hitting the top of the downward tilting mounting frame 251 and getting stuck. The road panel slides down along the pulleys 254 on the guide frame 253, allowing the road panel's pins to smoothly enter between the deflectors 285 of the chain 284, where the deflectors 285 guide the road panel to slide down in an orderly manner.

[0040] Please see Figures 1 to 9The container guiding assembly 300 includes a third pallet platform 310, a container guiding frame 320, a sliding guide rail 330, a traction winch 340, and a traction rope 350. The container guiding frame 320 is installed on the upper side of the third pallet platform 310. The sliding guide rail 330 is fixedly connected to the left and right ends inside the conversion container frame 230. The sliding guide rail 330 slopes upward from the rear end to the front end, and the upper end of the sliding guide rail 330 abuts and aligns with the lower end of the first sliding rail 290. The traction winch 340 is located at the left and right ends of the container guiding frame 320, and one end of the traction rope 350 is wound around the traction winch 340. It should be noted that the third pallet platform 310, the second pallet platform 210, and the first pallet platform 110 have the same structure, and the two sides of the third pallet platform 310, the second pallet platform 210, and the first pallet platform 110 are connected to each other. The upper ends of the conversion container frame 230, the container guiding frame 320, and the container road module 400 are connected sequentially. The height of the conversion container rack 230 is increased by raising the base 220, making the first sliding rail 290 higher than the sliding guide rail 330. This facilitates the alignment of the upper end of the sliding guide rail 330 and the lower end of the first sliding rail 290, forming a continuous sliding channel. After the pavement panels are folded by the lever 285, they enter the container pavement module 400 through the sliding guide rail 330. Once a certain number of folded pavement panels have been folded, the traction winch 340 and traction rope 350 are used to press the folded pavement panels together, finally storing them into the container pavement module 400, completing the loading. Multiple container pavement modules 400 can be arranged side by side, using the traction winch 340 and traction rope 350 to pull the folded pavement panels sequentially to load multiple sets of container pavement modules 400. After all modules are loaded, the empty container pavement modules 400 are hoisted and loaded again.

[0041] Please see Figures 1 to 10 A working platform assembly 500 is provided on top of the conversion container assembly 200 and the guide container assembly 300. The working platform assembly 500 includes a working platform 510, a guardrail 520, and a step 530. The working platform 510 is located on top of the conversion container assembly 200. The guardrail 520 surrounds the upper perimeter of the working platform 510. The upper end of the step 530 is hinged to the working platform 510, and the lower end of the step 530 rests on the top of the guide container assembly 300. The working platform 510 is used to assist workers in standing during the removal and conversion of the road panel. The guardrail 520 protects workers and reduces the possibility of workers falling from the working platform 510. Workers can transfer from the conversion container assembly 200 to the guide container assembly 300 using the step 530.

[0042] Specifically, the working principle of the road surface removal conversion device is as follows: During use, the connecting base on the lower side of the removal drum bracket 130 is connected to the connecting seat 123 via a pin, completing the connection of the removal drum bracket 130. After the removal drum bracket 130 is installed, the tightening member 125 is raised so that it presses against the four corners on the lower side of the removal drum bracket 130, releasing the folded road surface. The end of the folded road surface is pulled to the pulley 254 of the guide frame 253 by the traction winch 340 and the traction rope 350. The top guide wheel 252 guides the road panel, reducing the risk of the road panel hitting the top of the downward tilting mounting frame 251 and getting stuck. Wheel 260 guides the folded road surface, reducing the possibility of the folded road surface getting stuck due to contact with the front mounting beam 240. The sliding guide wheel 250 and guide roller 260 guide the folded road surface onto the chain pusher 280. The drive motor 271 drives the drive shaft 273, which in turn drives the drive sprocket 274 to rotate on the mounting base 272. The drive sprocket 274 drives the chain 284 to rotate. The front follower sprocket 282 and the rear follower sprocket 283 rotate with the chain 284. The chain 284 is limited by a dedicated chain guide groove 286. When the chain 284 is running, the deflector 285 can actively push the folded road panel backward through the hook pin. When the road panel retraction and transition to lower resistance is high, the lever 285 can play an auxiliary pushing role. When the road panel slides unevenly, the lever 285 can act as a limiter to ensure that the road panel slides down in an orderly manner and will not slip and break out of the first lower rail 290. The road panel with the hook pin guided by the lever 285 will automatically fold under the action of gravity at the free end of the hook pin. The folded road panel is guided into the container road module 400 by the lower guide rail 330. After a certain number of folded road panels are reached, the traction winch 340 and the traction rope 350 help to press the folded road panels together, and finally the road panel is put into the container road module 400, completing the loading. Multiple container road modules 400 can be arranged side by side. The traction winch 340 and the traction rope 350 are used to pull the folded road panels to load multiple container road modules 400 in sequence. After all are completed, the empty container road modules 400 are hoisted and loaded again. This achieves the purpose of transferring the recycled folded road surface into the container road module 400 so as to carry out the next operation.

[0043] It should be noted that the specific model and specifications of the drive motor 271 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.
