Description

Technical Field

[0001] The invention relates to the technical field of building construction tools, in particular to a turnover type unloading platform for building engineering construction. Background Art

[0002] The unloading platform for construction engineering is one of the essential equipment for construction, which is mainly used for the turnover of materials. When high-rise building construction is carried out, after the construction of a certain construction floor is completed, the construction tools and materials of that construction floor need to be transferred to the next construction floor through the unloading platform. When the existing hopper is turned over, the turning angle cannot exceed 90 degrees, which causes some residual materials to remain in the hopper and need to be cleaned manually by workers.

[0003] Chinese patent publication number CN118668940B discloses a construction unloading platform with a flipping function, including a track-changing flipping mechanism; the track-changing flipping mechanism includes a mobile platform, a longitudinal shifting frame, a track, a threaded rod I, a threaded rod driving member I, a rotating rod, a rotating rod driving member, a hopper, a support arm, a blocking plate and a rotating tube; two tracks are longitudinally arranged and located on both sides of the mobile platform; two longitudinal shifting frames are located on both sides of the mobile platform and slide longitudinally along the two tracks respectively; the threaded rod I passes through the mobile platform and the longitudinal shifting frame, and the threaded rod I is threadedly connected to the mobile platform, The threaded rod I is driven to rotate by the threaded rod driving member I; the hopper is movably installed on the mobile platform, and support arms are fixed on both sides of the hopper; the rotating tube passes through the mobile platform and the support arm, the rotating tube is rotatably connected to the mobile platform, and the rotating tube is fixedly connected to the support arm; the rotating rod passes through the longitudinal frame and the rotating tube, the rotating rod is slidably connected to the rotating tube along the axial direction, the rotating rod and the rotating tube are set with limit stops along the circumferential direction, and the rotating rod is driven to rotate by the rotating rod driving member; two blocking plates are fixedly installed on the mobile platform, respectively located under the two support arms, and are used to limit the flipping angle of the support arm to be greater than 90 degrees.

[0004] Although the above scheme enables the hopper to flip more than 90 degrees, the flipping fulcrum of the above hopper is single and is prone to breakage during use. At the same time, although the hopper can flip more than 90 degrees, since the structure of the hopper is a rectangular structure and there is no corresponding cleaning unit inside the hopper, residual materials will still be attached to the hopper after long-term use. In addition, an exposed screw is used to drive the mobile platform, which is easily affected by fallen construction materials, thereby causing the mobile platform to be unable to move smoothly. Summary of the invention

[0005] In view of the above problems, a flip unloading platform for construction engineering is provided. The platform comprises a hopper as a cylindrical shell structure and a cleaning unit for automatically cleaning the hopper. After unloading is completed, some residual materials will still adhere to the hopper, and the cleaning unit arranged in the hopper starts to operate.

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Reference Figure 1 , Figure 2 and Figure 4-Figure 6A tipping unloading platform for construction engineering, comprising a mobile unit 1 and a bracket 2 arranged on the mobile unit 1, a hopper 3 for receiving construction materials is arranged on the bracket 2; the hopper 3 is a cylindrical shell structure, the hopper 3 horizontally arranged on the bracket 2 rotates around the axis of the hopper 3 itself, an opening 31 is opened on the side wall of the hopper 3, when feeding, the opening 31 is vertically arranged upward, when discharging, the opening 31 is vertically arranged downward, a placement groove 32 is opened on the side wall at one end of the hopper 3, a cleaning unit 4 is arranged in the placement groove 32, and the cleaning unit 4 includes a scraper 41 moving along the radial direction of the hopper 3 A plurality of scrapers 41 are provided, and the scrapers 41 are evenly arranged in the placement groove 32 around the axis of the hopper 3. The cleaning unit 4 also includes a rotating unit 43 for driving the scraper 41 to rotate around the axis of the hopper 3 in the hopper 3. A driving unit 42 for driving the scraper 41 to move in the hopper 3 along the axis direction of the hopper 3 is provided on the upper part of the hopper 3. After the hopper 3 is unloaded, the scraper 41 moves out of the placement groove 32 along the axis direction of the hopper 3, and then the scraper 41 moves in the radial direction of the hopper 3 and contacts the inner wall of the hopper 3. The sweeping area formed by one end of the scraper 41 toward the inner wall of the hopper 3 completely covers the inner wall of the hopper 3.

[0032] In the existing unloading platform for construction engineering, the hopper 3 for receiving materials is mostly a rectangular structure, and the materials received by the hopper 3 may stick during the transportation process, that is, after the hopper 3 pours out the materials, some materials still remain in the hopper 3. As the use time increases, even if the hopper 3 can be turned over more than 90 degrees, more and more materials will accumulate in the hopper 3, and the amount of materials that the hopper 3 can receive at a time will gradually decrease. If the hopper 3 is cleaned after each unloading, the above problems can be avoided. However, the existing cleaning methods require human intervention, which is labor-intensive, and because the hopper 3 is a rectangular structure, the corners of the hopper 3 are not easy to clean.

[0033] In order to avoid the above situation, the hopper 3 can be automatically cleaned after each unloading, thereby reducing the work intensity of the staff during cleaning. In this way, the shape of the hopper 3 is improved, and a cleaning unit 4 is set in the hopper 3. The specific structure and working process of the cleaning unit 4 are as follows: The hopper 3 is arranged on the bracket 2, and a moving unit 1 for driving the bracket 2 to move in the horizontal direction is arranged at the lower part of the bracket 2. The moving unit 1 is preferably a slide with dustproof function. When in use, the hopper 3 is located at one end of the moving unit 1, and the opening 31 on the hopper 3 is vertically upward, and the material to be transported is put into the hopper 3 from the opening 31. When the material in the hopper 3 is full, the moving unit 1 drives the hopper 3 to move to the other end of the moving unit 1 through the bracket 2 for unloading. When unloading, the hopper 3 rotates 180 degrees around its own axis, so that the opening 31 set on the hopper 3 is switched from a vertical upward state to a vertical downward state, thereby realizing unloading. However, after the unloading is completed, some residual materials will still adhere to the hopper 3, and the cleaning unit 4 set in the hopper 3 will start to operate. First, the driving unit 42 drives the scraper 41 to move out of the placement groove 32 along the axial direction of the hopper 3, and then all the scrapers 41 arranged around the axial direction of the hopper 3 move synchronously along the radial direction of the hopper 3, and the scraper 41 extends outward along the radial direction of the hopper 3. The scraper 41 stops moving after contacting the inner wall of the hopper 3, and then the rotating unit 43 drives all the scrapers 41 to rotate around the axis of the hopper 3. At the same time, the driving unit 42 continues to drive the scraper 41 to move along the axial direction of the hopper 3, so that the end of the scraper 41 facing the inner wall of the hopper 3 forms a sweeping area during the rotation process, and the sweeping area completely covers the inner wall of the hopper 3. The scraper 41 can scrape out the residual material attached to the hopper 3 during the rotation, thereby realizing automatic cleaning of the hopper 3.

[0034] It is worth noting that the speed at which the drive unit 42 drives the scraper 41 to move along the axis of the hopper 3 needs to match the speed at which the rotation unit 43 drives the scraper 41 to rotate around the axis of the hopper 3, that is, within the time for the scraper 41 to complete one rotation around the axis of the hopper 3, the distance that the drive unit 42 drives the scraper 41 to move needs to be smaller than the width of the scraper 41 in the axis direction of the hopper 3, so that the sweeping area formed by the end of the scraper 41 toward the inner wall of the hopper 3 can completely cover the inner wall of the hopper 3.

[0035] Reference Figure 3 , Figure 6 and Fig.10 The cleaning unit 4 further comprises a cover shell 47 arranged inside the hopper 3 along the axis of the hopper 3, a rotating disk 45 is rotatably arranged inside the cover shell 47, a telescopic groove 46 is provided on the rotating disk 45 along the radial direction of the rotating disk 45, a plurality of telescopic grooves 46 are provided and are evenly distributed on the rotating disk 45 around the axis of the rotating disk 45, a scraper 41 is slidably arranged in the telescopic groove 46 along the extension direction of the telescopic groove 46, and a telescopic unit 44 for pulling the scraper 41 to move in the telescopic groove 46 is provided at the end of the rotating disk 45.

[0036] Reference Fig. 9 and Fig.10The telescopic unit 44 includes a guide plate 441 fixedly arranged in the cover shell 47 along the axis of the hopper 3, the guide plate 441 is located at one end of the rotating plate 45, and a plurality of inclined grooves 442 are evenly arranged on the guide plate 441 around the axis of the guide plate 441. The inclined grooves 442, the scraper 41 and the telescopic grooves 46 correspond to each other one by one, and there is an angle between the extension direction of the inclined grooves 442 and the telescopic direction of the telescopic grooves 46. A pushing block 443 is arranged in the telescopic groove 46 for movement along the extension direction of the telescopic groove 46, the pushing block 443 extends into the inclined groove 442 and slidably cooperates with the inclined groove 442, and a spring 444 is arranged between the pushing block 443 and the scraper 41, and the two ends of the spring 444 are fixedly connected to the pushing block 443 and the scraper 41 respectively. When the rotating plate 45 rotates, the inclined groove 442 guides the pushing block 443 to move.

[0037] Reference Figure 8 A first gear ring 451 is fixedly disposed at the end of the rotating disk 45 away from the guide disk 441, a first gear 452 is meshed on one side of the first gear ring 451, a first rotation driver 453 for driving the first gear 452 to rotate is disposed at the end of the first gear 452, and the first rotation driver 453 is fixedly disposed on the cover 47.

[0038] The first rotary driver 453 is preferably a steering gear, and the first rotary driver 453 drives the first gear ring 451 to rotate through the first gear 452, so that the rotating disk 45 rotates, and the guide disk 441 disposed at the end of the rotating disk 45 does not rotate, so that the rotating disk 45 and the guide disk 441 rotate relative to each other, so that under the guidance of the inclined groove 442, the push block 443 extending into the inclined groove 442 can be pulled by the inclined groove 442 and move in the telescopic groove 46. Before the first rotary driver 453 is operated, the driving unit 42 first drives the cover 47 to slide out of the placement groove 32, and then the first rotary driver 453 is restarted, so that after the push block 443 pushes the scraper 41 to rotate out through the spring 444, the scraper 41 can contact the inner wall of the hopper 3.

[0039] Reference Figure 7 and Figure 8 The rotating unit 43 includes a second gear ring 433 fixedly mounted on the outside of the housing 47, a second gear 432 is meshed on one side of the second gear ring 433, and a second rotation driver 431 for driving the second gear 432 to rotate is provided at the end of the second gear 432.

[0040] The second rotary driver 431 is preferably a servo motor. When the scraper 41 extends from the rotating disk 45, the second rotary driver 431 is started, and the second rotary driver 431 drives the second gear ring 433 to rotate through the second gear 432, thereby causing the cover 47 fixedly connected to the second gear ring 433 to start rotating. The rotating disk 45 located in the cover 47 stops rotating relative to the guide disk 441 after the scraper 41 extends, and the rotating disk 45 rotates synchronously with the cover 47, so that the scraper 41 arranged on the rotating disk 45 can rotate synchronously with the cover 47. During the rotation process, the scraper 41 scrapes off the residual material attached to the inner wall of the hopper 3. It is worth noting that since a spring 444 is provided between the push block 443 and the scraper 41, when the scraper 41 passes through the opening 31 of the hopper 3, a portion of the scraper 41 protrudes from the opening 31. In order to ensure that the protruding scraper 41 can be retracted smoothly, a chamfer is provided at the end of the scraper 41 so that the scraper 41 can be retracted faster after passing through the opening 31 of the hopper 3.

[0041] Reference Figure 7 The driving unit 42 includes a threaded rod 421 arranged on one side of the hopper 3 along the axial direction of the hopper 3, a movable plate 422 is fixedly arranged at one end of the cover shell 47, the threaded rod 421 penetrates the movable plate 422 and is threadedly matched with the movable plate 422, and a third rotating driver 423 for driving the threaded rod 421 to rotate is arranged at the end of the threaded rod 421.

[0042] Reference Figure 2 : A bellows 424 is sleeved on the outside of the threaded rod 421.

[0043] The third rotary driver 423 is preferably a servo motor. When the third rotary driver 423 is started, the third rotary driver 423 drives the moving plate 422 to move along the axis direction of the hopper 3 through the threaded rod 421. Since the cover 47 is fixedly arranged on the moving plate 422, when the moving plate 422 moves, the cover 47 can move synchronously. Since the upper part of the threaded rod 421 is provided with threads, when the opening 31 of the hopper 3 faces upward, during the process of loading the hopper 3, part of the material will fall on the threaded rod 421, causing the material to block the threads on the threaded rod 421, thereby causing the moving plate 422 to be unable to move smoothly. In order to avoid the above situation, a bellows 424 is sleeved on the outside of the threaded rod 421, and the two ends of the bellows 424 are respectively fixedly connected to one end of the hopper 3 and the moving plate 422. When the moving plate 422 moves, the bellows 424 will be synchronously extended and retracted. The material dropped from the outside can only fall on the bellows 424, ensuring the cleanliness of the surface of the threaded rod 421.

[0044] Reference Figure 4 and Figure 6: A flip unit 5 is provided at the end of the hopper 3 for driving the hopper 3 to rotate around its own axis. The flip unit 5 includes a third gear ring 52 fixedly provided at the end of the hopper 3. A third gear 53 is meshed with one side of the third gear ring 52. A fourth rotation driver 51 for driving the third gear 53 to rotate is provided at the end of the third gear 53. The diameter of the third gear 53 is smaller than the outer diameter of the third gear ring 52.

[0045] The fourth rotary driver 51 is preferably a servo motor. Since the hopper 3 containing the material is heavy, when the traditional hopper 3 is turned over, the force on the turning fulcrum of the hopper 3 is relatively large. The hopper 3 in the present invention is a cylindrical shell structure. When the hopper 3 rotates, the material in the hopper 3 will also tumble. Since the diameter of the third gear 53 is smaller than the outer diameter of the third gear ring 52, the hopper 3 in the present invention will not be subjected to unilateral force when unloading, thereby ensuring that the turning fulcrum of the hopper 3 will not be broken when the hopper 3 is turned over.

[0046] Reference Figure 2 A cleaning plate 6 is provided at the end of the hopper 3 on the side opposite to the placement groove 32. The cleaning plate 6 rotates around the axis of the hopper 3. The sweeping area formed when the cleaning plate 6 rotates coincides with the cross-sectional area of ​​the hopper 3 in the vertical direction and is equal in size.

[0047] A fifth rotary driver 61 for driving the cleaning plate 6 to rotate is provided at one end of the cleaning plate 6. The fifth rotary driver 61 is preferably a servo motor. When the driving unit 42 drives the movable plate 422 to move to the end of the hopper 3 where the cleaning plate 6 is provided, the fifth rotary driver 61 starts to run, and the cleaning plate 6 scrapes off all residual materials attached to the end surface of the movable plate 422.

[0048] Reference Figure 1-Figure 10 The end of the scraper 41 facing the inner wall of the hopper 3 is chamfered.

[0049] Working principle: When in use, the hopper 3 is located at one end of the mobile unit 1, and the opening 31 on the hopper 3 is vertically facing upwards, and the material to be transported is put into the hopper 3 from the opening 31. When the material in the hopper 3 is full, the mobile unit 1 drives the hopper 3 to move to the other end of the mobile unit 1 through the bracket 2 for unloading. When unloading, the hopper 3 rotates 180 degrees around its own axis, so that the opening 31 set on the hopper 3 switches from a vertical upward state to a vertical downward state, thereby realizing unloading. However, after unloading, some residual materials will still adhere to the hopper 3, and the cleaning unit 4 set in the hopper 3 will start to operate. First, the driving unit 42 drives the scraper 41 to move out of the placement groove 32 along the axial direction of the hopper 3, and then all the scrapers 41 arranged around the axial direction of the hopper 3 move synchronously along the radial direction of the hopper 3, and the scraper 41 extends outward along the radial direction of the hopper 3. The scraper 41 stops moving after contacting the inner wall of the hopper 3, and then the rotating unit 43 drives all the scrapers 41 to rotate around the axis of the hopper 3. At the same time, the driving unit 42 continues to drive the scraper 41 to move along the axial direction of the hopper 3, so that the end of the scraper 41 facing the inner wall of the hopper 3 forms a sweeping area during the rotation process, and the sweeping area completely covers the inner wall of the hopper 3. The scraper 41 can scrape out the residual material attached to the hopper 3 during the rotation, thereby realizing automatic cleaning of the hopper 3.

[0050] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
