Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a construction waste conveying elevator for high-rise building construction. Background Technology

[0002] During the construction of high-rise buildings, as the structure progresses upwards layer by layer, multiple processes such as formwork erection, rebar tying, concrete pouring, masonry construction, and decoration are carried out successively. Due to the narrow working area, frequent material cutting, and constant demolition and repair, a large amount of scrap, waste, fragments, and packaging materials are inevitably generated. These construction wastes are collectively referred to as construction waste. For the removal of waste from each floor, lower floors usually rely on manual labor to carry the waste bags by hand, transporting them one bag at a time via stairs or construction elevators. However, as the floor height increases, the efficiency of manual handling drops sharply, and the safety risks also increase. Therefore, elevators are commonly used for transfer. The current practice is to install winches near the upper working area, using drum assemblies and ropes to suspend the waste bins. After starting the winch, the waste bins can move up and down along the facade or hoist, thereby transporting the upper-level waste to a ground collection point.

[0003] However, after the garbage bins filled with debris land, the ropes must first be unfastened to the bins, then the bins must be dragged to a temporary storage area before the doors are opened to unload the waste. When the empty bins are returned to the upper floors for reloading, the steps of re-attaching the ropes, fastening the ropes, and sealing the doors must be repeated. This back-and-forth disassembly and assembly not only frequently interrupts the lifting process and reduces the continuity of vertical transport, but also causes increased wear on the rope ends and the lifting points of the bins due to repeated fastening, and the sealing strips are also prone to loosening, making it difficult to maintain a secure connection and a tight seal at the bin opening. At the same time, workers need to bend over, drag, align, and tighten the ropes multiple times, significantly increasing their physical labor, lengthening the operation process, and consequently reducing the overall waste collection efficiency. Therefore, this invention proposes a construction waste conveying elevator for high-rise building construction to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a construction waste conveying elevator for high-rise building construction, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a construction waste conveying elevator for high-rise building construction, comprising: guide rods, wherein the number of guide rods is set to four, and the four guide rods are arranged in a rectangular shape; A garbage bin is slidably installed between four guide rods. A connecting frame is fixedly installed on the top of one side of the garbage bin, and an openable baffle is installed on the opposite side. A rotating frame is fixedly connected to the top of the baffle, and a drive assembly is installed on the lower side of the connecting frame. The drive assembly is connected to the rotating frame for transmission, and is used to drive the rotating frame to rotate the baffle to the top of the garbage bin so that the baffle switches between the open position and the closed position. A connecting lug is fixedly connected to the upper surface of the rotating frame. A support plate is set above the connecting lug. The two sides of the support plate are fixedly connected to two guide rods. A winch is fixedly installed on the upper surface of the support plate. The end of the wire rope installed on the winch is fixedly connected to the connecting lug.

[0006] Preferably, each guide rod has a guide groove on the side near the trash can, and each guide rod has several mounting brackets fixedly connected on the side away from the trash can.

[0007] Preferably, a number of reinforcing rods are detachably connected between two guide rods on the same side of the trash can by bolts, and the number of reinforcing rods are arranged in a vertical linear array.

[0008] Preferably, rollers are fixedly installed on both sides of the trash can near the guide rod, and the rollers are in rolling connection with the guide groove.

[0009] Preferably, limiting rods are fixedly sleeved on both sides of the bottom of the connecting frame, and a guide plate is provided on one side of each limiting rod. The top of the guide plate is welded to the connecting frame, and a guide hole is opened at the bottom of the guide plate.

[0010] Preferably, the drive assembly includes a motor, which is fixedly connected to the end of the two limit rods away from the baffle. The output end of the motor is fixedly connected to one end of the threaded rod. The other end of the threaded rod passes through the connecting frame and is rotatably sleeved on the other end of the connecting frame. A movable block is threaded onto the threaded rod. The two ends of the movable block are slidably sleeved on the limit rods. A first support frame and a second support frame are fixedly connected to the side of the movable block away from the motor. The first support frame and the second support frame are arranged symmetrically.

[0011] Preferably, the ends of the first support frame and the second support frame away from the moving block are rotatably connected to the connecting frame via a limiting shaft. The ends of the first support frame and the second support frame closer to the moving block are rotatably fitted with a connecting shaft. Both ends of the connecting shaft are fixedly connected to the top of the connecting plate. The bottom end of the connecting plate is rotatably fitted with a guide wheel, which is slidably installed in the guide hole.

[0012] Preferably, a rack is slidably engaged at the bottom of the first support frame, a drive gear is engaged on one side above the rack, and a driven gear is engaged on the other side above the rack. The drive gear is fixedly sleeved on the connecting shaft, and the driven gear is fixedly sleeved on the limiting shaft.

[0013] Preferably, a wedge is fixedly connected to the bottom of the trash can, and several fixed frames are fixedly installed above the wedge. Each of the fixed frames is fitted with a rotating wheel on its top. The upper surface of the wedge is fixedly connected to the wedge plate through a fixed column, and the rotating wheel is installed in a through hole opened on the upper surface of the wedge plate.

[0014] Preferably, a set of fixing plates is fixedly connected to the side wall of the support plate near the baffle, and two fixing shafts are fixedly connected between the two fixing plates, with a rotating roller rotatably sleeved on each fixing shaft.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The garbage bin, in conjunction with four guide rods and a top winch, can rise and fall smoothly along the wall, maintaining a constant connection with the steel cable throughout the entire process without the need for repeated disassembly and reassembly. With the help of a motor-driven tilting baffle, the baffle automatically flips up to be almost flush with the top of the bin after it lands. The garbage then slides out smoothly under the guidance of a sloping plate with wheels, eliminating the need to move the bin before opening the door. During the ascent, material can be directly fed through the open opening, eliminating the need for repeated cable hanging and door sealing. This allows for continuous unloading and loading, reducing labor and wear on the connection between the bin and the cable, thus improving waste collection efficiency. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1 to 7 This invention provides a technical solution: a construction waste conveying elevator for high-rise building construction, comprising: four guide rods 1 arranged in a rectangular and vertical configuration to facilitate subsequent guidance and support of a waste bin 2; a waste bin 2 slidably mounted between the four guide rods 1; the top of the waste bin 2 being open; a connecting frame 3 fixedly mounted on one side of the top of the waste bin 2, allowing the waste bin 2 to move synchronously via the connecting frame 3; and an openable baffle 4 on the opposite side, with a rotating frame 5 fixedly connected to the top of the baffle 4; and a drive mechanism on the lower side of the connecting frame 3. The drive assembly is connected to the rotating frame 5 for driving the rotating frame 5 to rotate the baffle 4 to the top of the garbage bin 2, so that the baffle 4 can switch between the open and closed positions, thereby facilitating the loading and unloading of garbage. The upper surface of the connecting frame 3 is fixedly connected to the connecting ear 6, and a support plate 7 is set above the connecting ear 6. The two sides of the support plate 7 are fixedly connected to two guide rods 1. The upper surface of the support plate 7 is fixedly installed with a winch 8, and the support plate 7 provides stable support for the winch 8. The end of the wire rope installed on the winch 8 is fixedly connected to the connecting ear 6. The winch 8 is electrically connected to the external control equipment.

[0020] In use, four guide rods 1 are fixedly installed on the floor walls of high-rise buildings. The guide rods 1 are made of galvanized steel, and their specific height can be customized according to the required height for on-site construction. Simultaneously with the installation of the guide rods 1, the garbage bin 2 is placed between the four guide rods 1 to guide and limit the movement of the garbage bin 2, preventing it from swaying during lifting and lowering, thus improving the stability of garbage transfer. After the guide rods 1 are fixed, one end of the steel cable wound on the drum of the winch 8 is wound and fixed to the connecting lug 6. The winch 8 can then be started, and the lifting and lowering of the garbage bin 2 is controlled by the winding and unwinding of the steel cable. The garbage bin 2 moves under the limiting guidance of the guide rods 1. Upon reaching the ground, the rotating frame 5, driven by the blocking component, rotates the baffle 4, opening it. At this point, the baffle 4 flips to be roughly parallel to the upper surface of the garbage bin 2, allowing the garbage inside to be removed. This avoids the hassle of operators first untying the rope from the bin, dragging the bin to a temporary storage area, and then opening the door to unload the garbage. The garbage bin 2 is then driven upwards by the driving component. When it reaches the preset position, since both sides of the top of the garbage bin 2 are open, the packaged garbage can be placed directly inside, avoiding the need to repeat the steps of hanging the rope, locking, and sealing the door. This improves the efficiency of garbage transfer and reduces labor intensity.

[0021] Each guide rod 1 has a guide groove 9 on the side near the garbage bin 2. Each guide rod 1 has several mounting brackets 10 fixedly connected to the side away from the garbage bin 2. The mounting brackets 10 have several mounting holes to facilitate the fixed connection between the mounting brackets 10 and the wall, thereby fixing and limiting the guide rod 1 and ensuring the stability of the guide rod 1 in limiting and guiding the garbage bin 2. Several reinforcing rods 11 are detachably connected between two guide rods 1 on the same side of the garbage bin 2 by bolts. The reinforcing rods 11 are arranged in a vertical linear array. The reinforcing rods 11 further reinforce the guide rods 1 on the same side, thereby improving the stability of the overall device and further ensuring that the garbage bin 2 can move vertically and smoothly, avoiding the phenomenon of garbage spillage during transportation.

[0022] Rollers 12 are fixedly installed on both sides of the trash can 2 near the guide rod 1. The rollers 12 are in rolling connection with the guide groove 9. The sliding connection between the rollers 12 and the guide groove 9 improves the flexibility of the trash can 2 in moving.

[0023] Limiting rods 13 are fixedly sleeved on both sides of the bottom of the connecting frame 3. Each limiting rod 13 is provided with a guide plate 14 on one side. The top of the guide plate 14 is welded and fixed to the connecting frame 3. The bottom of the guide plate 14 is provided with a guide hole 15. The lower surface of the guide plate 14 is also welded and fixed to the garbage bin 2, so as to indirectly drive the garbage bin 2 to move synchronously.

[0024] The drive assembly includes a motor 16, which is electrically connected to an external control device. The motor 16 is fixedly connected to one end of two limiting rods 13 away from the baffle 4. The output end of the motor 16 is fixedly connected to one end of a threaded rod 17. The other end of the threaded rod 17 passes through a connecting frame 3 and is rotatably sleeved on the other end of the connecting frame 3. The connecting frame 3 provides limiting support for the threaded rod 17 to ensure its rotational stability. A movable block 18 is threaded onto the threaded rod 17. Both ends of the movable block 18 are slidably sleeved on the limiting rods 13, which further limit the movement of the movable block 18. A first support frame 19 and a second support frame 20 are fixedly connected to the side of the movable block 18 away from the motor 16. The first support frame 19 and the second support frame 20 are symmetrically arranged. The first support frame 19 and the second support frame 20 are located away from the movable rod 16. One end of block 18 is rotatably connected to connecting frame 3 via limiting shaft 21. Connecting shaft 22 is rotatably sleeved on the first support frame 19 and the second support frame 20 near the end of moving block 18. The first support frame 19 and the second support frame 20 support the limiting shaft 21 and connecting shaft 22. Both ends of connecting shaft 22 are fixedly connected to the top of connecting plate 23. Guide wheel 24 is rotatably sleeved on the bottom of connecting plate 23. Guide wheel 24 is slidably installed in guide hole 15. Guide hole 15 guides and limits guide wheel 24. Rack 25 is slidably engaged at the bottom of first support frame 19. Drive gear 26 meshes on one side above rack 25. Drive gear 27 meshes on the other side above rack 25. Drive gear 26 is fixedly sleeved on connecting shaft 22. Drive gear 27 is fixedly sleeved on limiting shaft 21.

[0025] When the baffle 4 is in a vertical position and closed on one side of the garbage bin 2, and it is necessary to open the baffle 4, the control motor 16 is started. The motor 16 drives the threaded rod 17 to rotate. Under the action of the rotation of the threaded rod 17, the threaded rod 17 drives the moving block 18 to move. The moving block 18 moves along the axis of the threaded rod 17 under the limit of the limit rod 13 and moves towards the direction closer to the motor 16. The moving block 18 drives the first support frame 19 and the second support frame 20 to move synchronously. The first support frame 19 and the second support frame 20 drive the limit shaft 21 and the connecting shaft 22 to move synchronously. The connecting shaft 22 is fixedly connected to the connecting plate 23. The connecting plate 23 drives the guide wheel 24 to slide upward from the bottom of one end of the guide hole 15. The movement of the guide wheel 24 indirectly drives the connecting shaft 22 to rotate counterclockwise. The connecting shaft 22 then drives the drive gear 26 to rotate, which in turn meshes with the rack 25, causing the rack 25 to move away from the motor 16 within the first support frame 19. Simultaneously, the rack 25 also meshes with the driven gear 27, driving the driven gear 27 to rotate. The driven gear 27 drives the limit shaft 21 to rotate, which in turn drives the rotating frame 5 to rotate upward. The rotating frame 5 then drives the baffle 4 to rotate upward. As the moving block 18 continues to move, the baffle 4 eventually reaches the top of the garbage bin 2 and is parallel to the upper surface of the garbage bin 2. At this point, the garbage can be easily removed. Then, by controlling the motor 16 to rotate in the opposite direction, the baffle 4 can be quickly reset.

[0026] The bottom of the trash can 2 is fixedly connected to an inclined block 28. Several fixed brackets 29 are fixedly installed above the inclined block 28. The top of each fixed bracket 29 is fitted with a rotating wheel 30. The fixed bracket 29 provides limiting support for the rotating wheel 30. The upper surface of the inclined block 28 is fixedly connected to the inclined plate 31 through a fixed column. The rotating wheel 30 is rotatably installed in the through hole 32 opened on the upper surface of the inclined plate 31.

[0027] When the baffle 4 is opened, the inclined block 28 supports the inclined plate 31, causing the garbage to tend to move out of the garbage bin 2. At the same time, the several rotating wheels 30 mounted on the inclined plate 31 reduce the friction of garbage removal, making it easier for operators to remove the garbage smoothly.

[0028] A set of fixing plates 33 are fixedly connected to the side wall of the support plate 7 near the baffle 4. Two fixing shafts 34 are fixedly connected between the two fixing plates 33. Each fixing shaft 34 is rotatably fitted with a rotating roller 35. The fixing plates 33 fix and support the fixing shafts 34, and the fixing shafts 34 limit and support the rotating rollers 35. The cable on the winch 8 is wound around the two fixing shafts 34 in an "S" shape before being tightly tied to the connecting ear 6. This ensures that the steel cable is aligned and straightened before entering the winding roller, preventing the steel cable from becoming loose on the winding roller. It also reduces friction and prevents damage to the outer sheath, breakage or deformation of the internal steel wires.

[0029] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
