Description

Technical Field

[0001] The invention belongs to the technical field of building engineering construction, and more specifically, particularly relates to a technology for vertically transporting construction waste using an elevator shaft. Background Art

[0002] In the design and construction of modern buildings, the basement, as an important component, is basically set in the building structure. The basement is usually a relatively closed space. Its unique location and structural characteristics make it face many challenges in the treatment of construction waste. Among them, tower cranes cannot lift construction waste in the basement due to their working range and structural limitations. In the previous construction process, there are two main methods of basement waste treatment. One is to leave a slab hole. By reserving a hole on the floor slab, the construction waste in the basement is lifted to the upper floor. However, this method will leave quality risks and may affect the structural stability and safety of the building. Another method is to use the basement driveway for transportation, that is, to transport the construction waste out through the basement driveway, but this method is time-consuming and labor-intensive, which not only increases the construction cost, but also affects the construction progress. It is not practical enough and needs to be improved. Summary of the invention

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, by setting up a construction waste transportation structure, the staff can control the start-up of the hoist body of the lifting structure, so that the hoist body drives the wire rope through the winch and the mechanical speed limiting pulley to drive the garbage bin to move up and down inside the stairwell assembly. Compared with the method of transporting garbage layer by layer through the basement driveway, it can effectively improve the construction efficiency, and can also be used as a small-scale construction material transportation device to reduce manpower consumption. Garbage transportation in a closed space can reduce dust, has promotion and application value, and is more practical.

[0014] In the present invention, a guide rod is arranged inside the stairwell assembly, so that when the staff operates the hoist body of the lifting structure to start and drive the garbage bin to move up and down inside the stairwell assembly, the movement of the garbage bin will drive the roller body on the guide chain to slide on the guide rod, thereby reducing the shaking and tilting amplitude of the garbage bin, preventing it from getting stuck, and improving reliability.

[0015] In the present invention, when the construction waste inside the garbage bin is not suitable for unloading through the lower opening door assembly, the electric push rod is turned on to cause the electric push rod to drive the push plate to retract, so that the push plate can push the garbage inside the garbage bin out of the garbage bin to transport the construction waste out, thereby most of the construction waste inside the garbage bin can be transported out at one time, thereby improving practicality.

[0016] In the present invention, since the garbage bin is made of closed railings, a guide rod is arranged inside the stairwell assembly to prevent the garbage bin from tilting significantly during movement. At the same time, since a lower door assembly is arranged below the garbage bin and a lifting ring and a swing door are arranged at the opening of the stairwell assembly, it can greatly facilitate the staff to unload construction waste, provide a variety of options, and improve practicality.

[0017] In the present invention, a mechanical speed limiting pulley is used as a speed limiting device. Since the winch is provided with safety limiters such as a lifting height limiter, an overload limiter, and a travel limiter, emergency braking can be performed in the event of sudden accidents such as power outages. At the same time, manual control can be adopted to lower the garbage bin to the bottom layer, thereby improving protection, avoiding accidents, and increasing safety.

[0018] In the present invention, by opening a circular hole on the electric protection automatic door group, it is possible to avoid affecting the setting of the electric protection automatic door group and causing the movement of the garbage bin inside the stairwell assembly. At the same time, since a distance sensor is provided on the electric protection automatic door group, when the garbage bin moves to the electric protection automatic door group inside the stairwell assembly, the electric protection automatic door group can open automatically, thereby improving the convenience of operation.

[0035] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] See also Figure 1 - Figure 8 The present invention provides a technology for vertically transporting construction waste using an elevator shaft, comprising a building body 27:

[0037] Including a construction waste transportation structure provided inside the building body 27;

[0038] The construction waste transportation structure includes a stairwell assembly 4, which includes a plurality of main beam bodies 3 and secondary beam bodies 8, each of which is arranged horizontally, and each of which is arranged vertically. The inner side of the overall shape after the combination of each main beam body 3 and the secondary beam body 8 is a square hollow area, and four or more main beam embedded bolts 7 are arranged between the upper end of each main beam body 3 and the building body 27, and a cross arm 9 is arranged on the lower end of each main beam body 3 and the side walls of both ends of the secondary beam body 8, and a U-shaped bolt 10 is arranged on the side wall of each cross arm 9, and the bolts of each U-shaped bolt 10 are partially exposed outside the cross arm 9 and are fixed to the building body 27 with a nut, and the opening direction of each U-shaped bolt 10 is upward. In terms of direction, a fixed protective plate 26 is provided at the upper end of the hollow area of ​​the combined shape of each main beam body 3 and the secondary beam body 8, and a lifting structure is provided at the upper end of the building body 27. By setting up a construction waste transportation structure, the staff can control the hoist body 1 of the lifting structure to start, so that the hoist body 1 drives the wire rope 5 through the winch 24 and the mechanical speed limiting pulley 22 to drive the garbage bin 6 to move up and down inside the stairwell assembly 4. Compared with the method of transporting garbage layer by layer through the basement driveway, it can effectively improve the construction efficiency, and can also be used as a small-scale building material transportation device to reduce manpower consumption. Garbage transportation in a closed space can reduce dust, has promotion and application value, and is more practical.

[0039] The lifting structure includes a hoist body 1 and a mechanical speed limiting pulley 22, a hoist embedded bolt 23, a winch 24 and an anchor bolt 25. The hoist embedded bolt 23 is threadedly installed between the hoist body 1 and the building body 27, and the anchor bolt 25 is threadedly installed between the winch 24 and the fixed protective plate 26. A wire rope 5 is provided on the hoist body 1, and the wire rope 5 is adapted to the winch 24 and the mechanical speed limiting pulley 22. By using the mechanical speed limiting pulley 22 as a speed limiting device, since the winch 24 is internally provided with a lifting height limiter, an overload limiter, a stroke limiter and other safety limiters, emergency braking can be performed in the event of sudden accidents such as power outages. At the same time, manual control can be adopted to lower the garbage bin 6 to the bottom layer, thereby improving protection, avoiding accidents and increasing safety. At the same time, a fence can be set on the outside of the fixed protective plate 26 to further improve the protection effect.

[0040] Each square hollow area formed by the combination of the main beam body 3 and the secondary beam body 8 is hinged with multiple electric protection automatic door groups 11 through single-axis hinges. Each electric protection automatic door group 11 is made of steel plates. A circular hole is provided at the center of each electric protection automatic door group 11. By providing a circular hole on the electric protection automatic door group 11, it is possible to avoid affecting the setting of the electric protection automatic door group 11 and causing the movement of the garbage bin 6 inside the stairwell assembly 4. At the same time, since a distance sensor is provided on the electric protection automatic door group 11, when the garbage bin 6 moves to the electric protection automatic door group 11 inside the stairwell assembly 4, the electric protection automatic door group 11 can open automatically, thereby improving the convenience of operation.

[0041] Each steel wire rope 5 can slide through the circular hole, and a two-link switch mechanism is provided at the lower end of each electric protection automatic door group 11. Each two-link switch mechanism includes a group of gears 12 and a group of connecting rod bodies 13. Each connecting rod body 13 is fixedly installed at the upper end of the gear 12, and the end of each connecting rod body 13 is rotatably installed with the door body of the electric protection automatic door group 11. A trash bin 6 is provided inside the hollow area of ​​the square grid, and pull rings are fixedly installed at the four corners of the upper end of the trash bin 6. The pull ring at the upper end of the trash bin 6 is fixedly installed with the steel wire rope 5, and the horizontal angle formed by the connection between the steel wire rope 5 and the pull ring at the upper end of the trash bin 6 is between 45° and 60°.

[0042] The center of gravity of the wire rope 5 and the garbage bin 6 after being combined is in an overlapping state, a lower opening door assembly 20 is provided at the lower end of the garbage bin 6, an angle limiter 19 is provided between the lower opening door assembly 20 and the garbage bin 6, a lower opening door bolt 21 is provided between the lower opening door assembly 20 and the lower end of the garbage bin 6, a lifting ring 18 is provided at the opening of the stairwell assembly 4, a swing door is rotatably installed at the lower end of the lifting ring 18, and the garbage bin 6 is made of closed guardrails. Since the garbage bin 6 is made of closed guardrails, a guide rod 2 is provided inside the stairwell assembly 4 to avoid the garbage bin 6 from tilting significantly during movement. At the same time, since the lower opening door assembly 20 is provided below the garbage bin 6 and the lifting ring 18 and the swing door are provided at the opening of the stairwell assembly 4, it can greatly facilitate the staff to unload construction waste, provide a variety of options, and improve practicality.

[0043] A plurality of wall-connecting chains 15 are fixedly installed inside the stairwell assembly 4, and a guide rod 2 is fixedly installed between each wall-connecting chain 15. A wall-connecting chain 15 is fixedly installed on the side wall of the trash bin 6 close to the guide rod 2. A guide chain 14 is provided on the side wall of the trash bin 6. The guide chain 14 and the wall-connecting chain 15 are adapted to the guide rod 2. A roller holder 17 is provided on the surface of the guide chain 14. A plurality of roller bodies 16 are fixedly installed on the inner side of each roller holder 17. Each roller body 16 is fitted with the surface of the guide rod 2 in a surrounding state. The roller body 16 is made of polyethylene plastic pipe. By arranging the guide rod 2 inside the stairwell assembly 4, when the staff operates the hoist body 1 of the lifting structure to start and drive the trash bin 6 to move up and down inside the stairwell assembly 4, the movement of the trash bin 6 will drive the roller body 16 on the guide chain 14 to slide on the guide rod 2, thereby reducing the shaking and tilting amplitude of the trash bin 6, preventing it from getting stuck, and improving reliability.

[0044] An electric push rod 28 is fixedly installed inside the trash bin 6, and the output shaft direction of the electric push rod 28 is toward the inside of the trash bin 6. A push plate 29 is fixedly installed on the inner wall of the trash bin 6. The push plate 29 and the output shaft of the electric push rod 28 are fixedly installed. The push plate 29 is slidably installed with the trash bin 6, and the push plate 29 is slidably installed with the lower door assembly 20. When the construction waste inside the trash bin 6 is not suitable for unloading through the lower door assembly 20, the electric push rod 28 is turned on, so that the electric push rod 28 drives the push plate 29 to retract, so that the push plate 29 can push the garbage inside the trash bin 6 out of the trash bin 6 and transport the construction waste out, so that most of the construction waste inside the trash bin 6 can be transported out at one time, thereby improving practicality.

[0045] Working principle:

[0046] In the first step, when using, the staff can first operate the hoist body 1 of the lifting structure to start, so that the hoist body 1 drives the wire rope 5 through the winch 24 and the mechanical speed limiting pulley 22 to drive the garbage bin 6 to move up and down inside the stairwell assembly 4. At the same time, the movement of the garbage bin 6 will drive the roller body 16 on the guide chain 14 to slide on the guide rod 2. When the garbage bin 6 moves to the garbage collection and transfer position, the staff can close the lifting structure at this time, and then the staff fills the garbage bin 6 with construction waste. After the construction waste is loaded, the staff can stop working. The personnel opens the electric protection automatic door group 11, so that the gear 12 and the connecting rod body 13 on the two-link switch mechanism of the electric protection automatic door group 11 drive the electric protection automatic door group 11 (the electric protection automatic door group 11 is the existing technology, mainly composed of a door body, a two-link switch mechanism, a motor, and a distance sensor) to open, and then the lifting structure can be controlled to start again, driving the garbage bin 6 to move slowly to the unloading position under the stairwell assembly 4, and then the staff can open the lower door bolt 21 of the lower door assembly 20, so that the construction waste can fall directly from under the garbage bin 6.

[0047] In the second step, when the height of the stairwell assembly 4 is greater than two floors or ten meters, a layer of electric protection automatic door group 11 and a manual normally closed protection door can be laid in the stairwell assembly 4. When the staff controls the hoist body 1 of the lifting structure to start, the hoist body 1 drives the wire rope 5 through the winch 24 and the mechanical speed limiting pulley 22 to drive the garbage bin 6 to move up and down inside the stairwell assembly 4. At this time, when the garbage bin 6 drops to one meter above the electric protection automatic door group 11, the sensor inside the electric protection automatic door group 11 will detect the garbage bin 6, so that the electric protection automatic door group 11 will open automatically. When the garbage bin 6 moves below the electric protection automatic door group 11, the electric protection automatic door group 11 will close automatically. If the garbage bin 6 needs to stop at the manual normally closed protection door, the staff manually controls the manual normally closed protection door to close, and controls the garbage bin 6 to stay above the manual normally closed protection door, thereby providing multiple protections.

[0048] The third step, when the construction waste inside the garbage bin 6 is not suitable for unloading through the lower opening door assembly 20, the staff can control the hoist body 1 of the lifting structure to start, so that the hoist body 1 drives the wire rope 5 through the winch 24 and the mechanical speed limiting pulley 22 to drive the garbage bin 6 to move inside the stairwell assembly 4, when the garbage bin 6 moves to about half a meter of the electric protection automatic door group 11, the staff can manually close the electric protection automatic door group 11, and open the lifting structure again to move the garbage bin 6 to the door body of the electric protection automatic door group 11, and open the swing door of the stairwell assembly 4, open the electric push rod 28, so that the electric push rod 28 drives the push plate 29 to retract, so that the push plate 29 can push the garbage inside the garbage bin 6 out of the garbage bin 6 to transport the construction waste out.

[0049] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art.
