Description

Technical Field

[0001] This application relates to the field of building engineering equipment technology, specifically a waste removal device for building construction floors. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at a designated location. It includes foundation construction, main structure construction, roof construction, decoration construction, etc. The place where construction work is carried out is called the "construction site" or "construction site".

[0003] During the construction process, a large amount of waste is generated, including slag, concrete blocks, gravel, brick and tile fragments, waste mortar, mud, asphalt blocks, waste plastics, waste metals, waste bamboo and wood, etc. Therefore, after the construction is completed, this waste needs to be transferred to the ground and then transported by engineering vehicles to designated disposal sites for treatment.

[0004] For example, the invention patent with publication number CN118083408A specifically discloses a construction waste collection and transportation device. This device is a waste collection vehicle that can effectively and automatically dump the loaded construction waste, thereby improving the performance of the waste collection and transportation device, as well as the efficiency of waste collection and transportation, and the safety of waste collection and treatment.

[0005] Currently, the process for removing construction waste from high-rise buildings requires workers to first bag the waste, then transport the bagged waste to an elevator using a waste collection vehicle, and finally pile the waste on the elevator to transport the waste from that floor to the ground for centralized disposal. However, this process not only requires a lot of manpower to clean up the waste, but also slows down the construction progress due to the repeated use of the elevator. Therefore, it is necessary to provide a waste removal device for building construction floors to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] Example 1:

[0044] This embodiment illustrates the device and its working principle for quickly transferring bagged construction waste (hereinafter referred to as waste bags) from different floors of a high-rise building to the ground. Specifically:

[0045] like Figure 1 As shown, this application provides a construction waste removal device for building floors, including a support 1. The support 1 is the support part of the waste removal device, which is usually placed on a flat ground or workbench to ensure the stable removal of construction waste. In this embodiment, the support 1 is set on the ground on one side of a high-rise building.

[0046] A waste collection mechanism 2 is installed on the support frame 1. This mechanism 2 is used to quickly transfer waste from each floor of the high-rise building to the ground. Specifically:

[0047] The cleaning mechanism 2 includes a base 25, and a vertical plate 11 is fixedly installed on the side of the support 1, so that the base 25 can be fixedly installed on the vertical plate 11 to fix the cleaning mechanism 2.

[0048] like Figures 1-3As shown, a cleaning cylinder 21 is vertically arranged on the base 25. The cleaning cylinder 21 is matched with the height of the high-rise building, so that the cleaning cylinder 21 can cover each floor of the high-rise building. In this embodiment, the cleaning cylinder 21 is composed of multiple cylinder sections assembled by fasteners, so that the cleaning cylinder 21 can be set according to the height of the high-rise building, and the assembled cleaning cylinder 21 is also easy to disassemble and store.

[0049] Meanwhile, an inlet 22 is provided on the collection cylinder 21 at the corresponding position of each floor. The inlet 22 is connected to the collection cylinder 21 to facilitate the staff to put in the garbage bag. An outlet 23 is provided at the bottom of the collection cylinder 21. The outlet 23 is connected to the collection cylinder 21 to discharge the garbage bag.

[0050] It is understandable that when garbage is collected from each floor of a high-rise building, the staff put garbage bags into the inlet 22 of each floor. The garbage bags then fall vertically in the collection tube 21 and reach the outlet 23 at the bottom. In this application, a collection trolley is set at the outlet 23 to receive the garbage bags discharged from the outlet 23.

[0051] In order to ensure that the garbage bags can be discharged smoothly, such as Figure 3 As shown, an elastic body (not shown in the figure) is fixedly installed on the base 25 in the vertical direction. A vibrating seat 28 is fixedly installed on the end of the elastic body away from the base 25, so that the vibrating seat 28 can perform elastic movements toward or away from the base 25.

[0052] Meanwhile, multiple sets of sleeves 24 are fixedly installed vertically on the collection cylinder 21. A first spring 26 is fixedly installed between the sleeve 24 and the vibrating seat 28, and a vibration motor 27 is installed on the vibrating seat 28. When the vibration motor 27 is started, the vibrating seat 28 can reciprocate and drive the sleeves 24 to vibrate synchronously, thereby driving the collection cylinder 21 to vibrate. When the collection cylinder 21 vibrates, it can assist in the discharge of garbage bags to prevent garbage bags from clogging the collection cylinder 21. The vibration of the collection cylinder 21 can shake off the garbage attached to the inside of the collection cylinder 21, thereby achieving a self-cleaning effect.

[0053] Example 2:

[0054] During the garbage bag removal process, because the garbage bag contains relatively hard parts such as scrap metal and concrete blocks, when the garbage bag falls freely from the collection cylinder 21, the impact force is relatively large and may damage the collection cylinder 21. In particular, if the garbage bag starts from a high position, it may penetrate the bottom of the collection cylinder 21.

[0055] To solve the above problems, such as Figure 2 and Figures 4-5As shown, a material blocking mechanism 3 is provided at the bottom of the collection cylinder 21. The material blocking mechanism 3 is used to buffer the garbage bag to prevent the impact of the garbage bag from damaging the bottom of the collection cylinder 21.

[0056] like Figure 4 and Figure 6 As shown, the material blocking mechanism 3 includes a box 31 fixedly installed on the base 25 near the collection cylinder 21. The box 31 has an opening, and a window 211 is provided on the collection cylinder 21 at a position corresponding to the opening. Thus, the blocking part of the material blocking mechanism 3 can pass through the opening and the window 211 and enter the interior of the collection cylinder 21 to block the falling garbage bag.

[0057] like Figures 8-9 As shown, a top frame 33 is fixedly installed at the top of the inside of the housing 31. A servo motor 32 is fixedly installed on the top frame 33. A rotating shaft 34 is fixedly installed at the output end of the servo motor 32. The rotating shaft 34 and the top frame 33 are mounted by bearings, so that the rotating shaft 34 can rotate under the drive of the servo motor 32.

[0058] Meanwhile, side plates 36 are rotatably provided at both ends of the top frame 33. The side plates 36 pass through the rotating shaft 34 and are coaxially arranged with the rotating shaft 34, so that the side plates 36 can rotate around the axis of the rotating shaft 34.

[0059] Furthermore, a drive wheel 35 is fixedly installed on the rotating shaft 34, and a tensioning shaft (not shown in the figure) is installed at the bottom of the side plate 36. A driven wheel 310 is fixedly installed on the tensioning shaft, and a belt 37 is provided between the driven wheel 310 and the drive wheel 35 for transmission. Thus, when the rotating shaft 34 rotates, the driven wheel 310 can be driven to rotate synchronously through the belt 37.

[0060] It should be noted that, as Figure 9 As shown, a groove 361 is provided at the bottom of the side plate 36. A bearing seat 38 is slidably disposed inside the groove 361, so that the tension shaft bearing can be installed on the bearing seat 38. Since the bearing seat 38 is adapted to slide in the groove 361, the position of the driven wheel 310 can be adjusted, thereby adjusting the tension of the belt 37. In this application, a screw 39 can be fixedly installed on the side plate 36, so that the bearing seat 38 can be sleeved on the screw 39, and the position of the bearing seat 38 can be adjusted by the nut.

[0061] Continue to refer to Figure 9 A first hinge seat 311 is hinged to the bottom of the side plate 36, and a second hinge seat 312 is fixedly installed at the bottom of the box body 31. A rotating rod 314 is rotatably mounted on the second hinge seat 312, and a second spring 313 is fixedly installed at the other end of the rotating rod 314. The other end of the second spring 313 is installed on the first hinge seat 311.

[0062] In summary, in the initial state, due to the action of the second spring 313, the side plate 36 rotates around the pivot 34 at a certain angle, causing the side plate 36 to be in an inclined state. When the side plate 36 is in the initial inclined state, the driven wheel 310 passes through the opening and window 211 and enters the interior of the cleaning cylinder 21. At this time, the distance between the driven wheel 310 and the side wall of the cleaning cylinder 21 is smaller than the size of the garbage bag, so that the garbage bag can be blocked at the top of the driven wheel 310.

[0063] Therefore, when the garbage bag enters the collection bin 21, it will fall freely under the action of gravity and be blocked by the driven wheel 310, thus achieving the buffering of the garbage bag and preventing it from damaging the bottom of the collection bin 21 when it falls rapidly.

[0064] When the garbage bag needs to be released, the servo motor 32 is turned on, which drives the belt 37 to transmit the garbage bag in the direction of output. At this time, the friction of the belt 37 drives the garbage bag to move and squeezes the second spring 313, causing the driven wheel 310 to rotate and move away from the side wall of the collection cylinder 21. This causes the garbage bag to pass over the driven wheel 310 and fall to the bottom of the collection cylinder 21. At this time, because the distance to the bottom of the collection cylinder 21 is short, the impact force of the garbage bag will generate a small load on the collection cylinder 21, thus protecting the collection cylinder 21.

[0065] Example 3:

[0066] During the process of the material blocking mechanism 3 blocking the garbage bag, if the garbage bag is on a high floor, the impact force may be huge. As the garbage bag falls freely, it will directly squeeze the driven wheel 310 and fall to the bottom of the collection cylinder 21. At this time, the impact force of the garbage bag is not completely buffered, which may still cause damage to the bottom of the collection cylinder 21.

[0067] To solve the above problems, such as Figure 7 and Figures 10-11 As shown, a limiting mechanism 4 is provided on the inner side of the housing 31, and a hook 5 is provided at the bottom of the side plate 36. The hook 5 is adapted to cooperate with the limiting mechanism 4 to restrict the position of the driven wheel 310. Specifically:

[0068] The limiting mechanism 4 includes a fixing block 41 fixedly installed on the inner side of the housing 31. A first channel 42 is horizontally arranged on the fixing block 41, and the first channel 42 passes through the fixing block 41 at the opening of the housing 31.

[0069] Meanwhile, the hook 5 includes a seat 51 fixedly installed at the bottom of the side plate 36, on which a rod 52 is rotatably mounted, and a ball 53 is fixedly installed at the end of the rod 52. The ball 53 is adapted to the first channel 42, and in the initial state, the ball 53 is located in the first channel 42.

[0070] It should be noted that the sphere 53 has an elastic structure, which allows the sphere 53 to always fit the bottom of the first channel 42 regardless of how the depth of the first channel 42 changes.

[0071] Continue to refer to Figure 10 A second channel 43 communicating with the first channel 42 is provided on the fixed block 41. The second channel 43 is inclined and the bottom position of the second channel 43 is lower than the bottom position of the first channel 42, so that when the ball 53 enters the second channel 43 from the first channel 42, it cannot return to the first channel 42.

[0072] Meanwhile, a third channel 45 is connected to the second channel 43 at a position away from the first channel 42. The bottom of the third channel 45 is lower than the bottom of the second channel 43, so that when the sphere 53 enters the third channel 45 from the second channel 43, it cannot return to the second channel 43. Furthermore, a first inflection point 44 is provided at the intersection of the third channel 45 and the second channel 43, and the first inflection point 44 is located inside the third channel 45.

[0073] In summary, in the initial state, the sphere 53 is located inside the first channel 42, and at this time the driven wheel 310 is located inside the cleaning cylinder 21 and is in a position to block the garbage bag;

[0074] When the garbage bag falls from the top of the collection cylinder 21, the impact force of the garbage bag will act on the driven wheel 310 and push the driven wheel 310 to move away from the inner wall of the collection cylinder 21, thereby increasing the distance between the driven wheel 310 and the inner wall of the collection cylinder 21.

[0075] As the driven wheel 310 moves, it will drive the side plate 36 to move synchronously, and drive the ball 53 from the first channel 42 into the second channel 43, and all the way to the first inflection point 44. When the ball 53 stops at the first inflection point 44, the side plate 36 is completely restricted and cannot continue to move, thus making the driven wheel 310 unable to move.

[0076] At this time, the distance between the driven wheel 310 and the inner wall of the collection cylinder 21 is still smaller than the size of the garbage bag, so the garbage bag is still restricted to the upper end of the driven wheel 310, thereby preventing the garbage bag from having too much force and passing over the driven wheel 310, which would damage the bottom of the collection cylinder 21.

[0077] Continue to refer to Figure 10A fourth channel 47 is connected to the third channel 45 at a position away from the second channel 43. The bottom surface of the fourth channel 47 is lower than the bottom surface of the third channel 45, so that when the sphere 53 enters the fourth channel 47 from the third channel 45, it cannot return to the third channel 45. A second inflection point 46 is provided at the junction of the fourth channel 47 and the third channel 45. The second inflection point 46 is located inside the fourth channel 47.

[0078] Meanwhile, a fifth channel 49 is connected to the fourth channel 47 at a position away from the third channel 45. The fifth channel 49 is divided into a first part connected to the fourth channel 47 and a second part connected to the first part. The bottom of the first part is lower than the bottom of the fourth channel 47, so that when the ball 53 enters the first part from the fourth channel 47, it cannot return to the fourth channel 47. A third inflection point 48 is set at the junction of the first part and the fourth channel 47. The third inflection point 48 is located in the first part of the fifth channel 49.

[0079] Furthermore, the second part is an inclined channel, and along the direction away from the first part, the bottom of the second part gradually rises, and at the highest point of the second part it connects with the first channel 42, forming a step at the connection with the first channel 42, so that the sphere 53 cannot directly enter the second part of the fifth channel 49 from the first channel 42;

[0080] In this embodiment, the distance between the third inflection point 48 and the starting end of the first channel 42 is greater than the distance between the first inflection point 44 and the starting end of the first channel 42. Therefore, when the sphere 53 is located at the third inflection point 48, the distance between the driven wheel 310 and the inner wall of the cleaning cylinder 21 will increase, allowing the garbage bag to pass through.

[0081] In this embodiment, a first switch (not shown in the figure) is provided at the second inflection point 46, which is used to turn on the servo motor 32. At the same time, a second switch (not shown in the figure) is provided at the third inflection point 48, which is used to turn off the servo motor 32.

[0082] In summary, when the garbage bag accumulates on the upper end of the driven wheel 310, due to the disappearance of the impact force, the driven wheel 310 will move towards the inner wall of the cleaning cylinder 21 under the action of the second spring 313. At this time, the ball 53 will enter the position of the second inflection point 46 along the third channel 45 and open the first switch.

[0083] When the first switch is turned on, the servo motor 32 starts and drives the belt 37 to start conveying, thereby using friction to make the garbage bag start to be conveyed. At the same time, the ball 53 will start to move along the fourth channel 47 until the ball 53 reaches the position of the third inflection point 48.

[0084] Before the ball 53 reaches the third inflection point 48, the gap between the driven wheel 310 and the inner wall of the cleaning cylinder 21 has increased to allow the garbage bag to pass through, thus realizing the transportation of the garbage bag. When the ball 53 reaches the third inflection point 48, the second switch will be triggered and the servo motor 32 will be turned off.

[0085] After the garbage bag passes the driven wheel 310, the driven wheel 310 begins to reset. At this time, the ball 53 will return to the first channel 42 along the fifth channel 49 and reach the initial position to prepare for the blocking and conveying of the next garbage bag.

[0086] This application also includes a PLC control system to facilitate the coordinated operation of various electrical components.

[0087] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
