Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a connection platform between a construction elevator and the main structure, and its working method. Background Technology

[0002] In modern construction, construction elevators (also known as construction hoists) have become indispensable equipment to meet the needs of vertical transportation during construction, especially in the construction of large factories or high-rise buildings. These construction elevators are usually installed around the perimeter of the building to efficiently transport personnel and materials. However, in practice, there are often gaps between the construction elevator and the main structure of the building. This design was originally intended to accommodate deviations in the layout during construction, but it also brings challenges to connection and safety.

[0003] Currently, to fill these gaps and build a connection platform between the construction elevator and the building, temporary structural materials such as discarded grating and wooden formwork are commonly used on construction sites. While these temporary materials solve the connection problem to some extent, their inherent defects cannot be ignored.

[0004] First, these temporary structural materials are prone to loosening during construction due to their poor stability and durability. Once loosened, they could collide with the construction elevator, potentially damaging the elevator's structure and causing a safety accident.

[0005] Secondly, if there are foreign objects, such as building material residue or tools, at the connection between the construction elevator and the building opening, they may cause safety problems or even cause the construction elevator to malfunction if they collide with the temporary structure.

[0006] Even more seriously, these temporary structures are prone to accumulating construction waste, pebbles, dust, debris, and other junk. As these objects fall, they can not only interfere with the operation of construction elevators but also directly injure construction workers below, seriously threatening the safety of the construction site.

[0007] Therefore, in order to address the above issues, it is necessary to improve and optimize the connection platform between the construction elevator and the main structure of the building to enhance its stability, safety, and reliability. Summary of the Invention

[0008] This invention provides a connection platform between a construction elevator and the main structure and its working method, which adopts an inductive flipping structure and a foreign object collection structure, effectively solving the safety problems existing in the current temporary structure.

[0009] In view of the above problems, the technical solution proposed by the present invention is as follows:

[0010] A connection platform between a construction elevator and the main structure includes:

[0011] The tilting platform includes a mounting frame fixedly installed on the wall at the opening of the main structure; and a tilting frame hinged to the mounting frame, the top of the tilting frame being fitted with a textured tread, and a first telescopic rod for driving the tilting frame to rotate is hinged between the mounting frame and the tilting frame.

[0012] The tilting collection bucket is set at the bottom of the tilting frame and includes a lifting lug that is hinged to the tilting frame. The lifting lug is connected to the bucket body. A second telescopic rod is set between the lifting lug and the tilting frame on the side away from the tilting frame. The two ends of the second telescopic rod are respectively hinged to the tilting frame and the lifting lug.

[0013] The sensing structure, mounted on the mounting frame, is used to sense the status of the connection between the construction elevator cage and the tilting platform;

[0014] It also includes a second sensor installed on the wall-mounted frame of the construction elevator for sensing the position of the hoist cage; and a controller, which is communicatively connected to the first telescopic rod, the second telescopic rod, the sensing structure, the second sensor, and the construction elevator.

[0015] In the working state, the controller controls the tilting frame to be in a horizontal state. At this time, the controller controls the tilting collection bucket to be folded to the bottom of the tilting frame. In the non-working state, the controller controls the tilting frame to be in a tilted state. At this time, the controller controls the tilting collection bucket to be unfolded to the outside of the tilting frame.

[0016] To better realize the technical solution of the present invention, the following technical measures were also adopted.

[0017] Furthermore, the flipping platform is elongated in shape, and the sensing structure includes a bracket and a first sensor. Extension rods are located on both sides of the mounting bracket, with the bracket mounted on the extension rods and the first sensor mounted on the bracket.

[0018] Furthermore, the first sensor is a grating sensor, used to sense whether there are obstacles at the connection between the construction elevator cage and the tilting platform; and to sense the position of the connection between the cage and the tilting platform. The signal output terminal of the first sensor is communicatively connected to the signal input terminal of the controller.

[0019] Furthermore, it also includes a collector, which is connected to one side of the bucket body via a collection pipe.

[0020] Furthermore, the collector contains a negative pressure generator and a collection box. The side wall of the collection box has a perforated structure. A filter screen is installed between the collection box and the negative pressure generator. The collection pipe is connected to the collection box. After the negative pressure generator is started, a negative pressure environment is formed inside the collector. The signal input terminal of the negative pressure generator is communicatively connected to the signal output terminal of the controller.

[0021] A method for operating a connection platform between a construction elevator and the main structure includes the following modes:

[0022] Mode 1:

[0023] The controller controls the first telescopic rod to extend fully and then closes it; and the controller controls the second telescopic rod to retract fully and then closes it.

[0024] At this point, the first telescopic rod extends the tilting frame to be perpendicular to the mounting frame; the second telescopic rod folds the tilting collection bucket to the bottom of the tilting frame;

[0025] Mode 2:

[0026] After the controller fully retracts the first telescopic rod, it closes the first telescopic rod; and the controller fully extends the second telescopic rod, and then closes the second telescopic rod.

[0027] At this point, the first telescopic rod folds the tilting frame, which is now tilted; the second telescopic rod unfolds the tilting collection bucket to the outside of the tilting frame.

[0028] Furthermore, it includes the following steps:

[0029] The controller collects signals from the second sensor in real time;

[0030] The first sensor is activated after the second sensor detects that the construction elevator cage has moved to the opening of the main structure floor.

[0031] The first sensor collects information at the connection point between the construction elevator cage and the tilting platform;

[0032] When the controller determines that there is no abnormality at the connection point and the construction elevator stops at the opening of the current floor, the controller starts mode one.

[0033] Furthermore, it includes the following steps:

[0034] The controller collects signals from the second sensor in real time;

[0035] After the second sensor fails to detect the construction elevator cage, the controller activates mode two after a first set time has elapsed.

[0036] Furthermore, it includes the following steps:

[0037] Controller startup mode two;

[0038] The controller turns on the negative pressure generator, creating a negative pressure environment in the data collector;

[0039] The debris inside the bucket is sucked into the collection box through the collection pipe;

[0040] After the second set time has elapsed, the controller shuts off the negative pressure generator.

[0041] Furthermore, when the controller detects an abnormality at the connection point, it will not activate mode one and will instead send a notification message to the construction elevator.

[0042] Compared with the prior art, the beneficial effects of the present invention are:

[0043] 1. It can identify the status of the connection between the construction elevator cage and the tilting platform. When there are no foreign objects at the connection between the construction elevator and the building opening, the connection platform will be opened automatically. When there are foreign objects, the connection platform will be closed, and a message will be sent to the construction elevator to remind it.

[0044] 2. Compared to existing temporary structures, it is more stable and is connected to the main structure without any loosening issues, ensuring the safe operation of the construction elevator.

[0045] 3. It can collect fallen construction waste, pebbles, dust, debris and other debris remaining on the connecting platform. In addition to keeping the connecting platform clean, it can also prevent them from falling and causing injury to the construction workers below.

[0046] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and in order to make the above and other objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention are described below.

[0059] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0060] like Figure 1 As shown, the wall 11 of the main structure 1 has openings 12 for transporting materials and allowing personnel to pass through. Currently, for vertical transport, a protective structure 13 is usually installed at the opening 12, and one or two openings are reserved as passageways.

[0061] The existing construction elevator 2 includes a guide rail frame 22 that is perpendicular to the wall 11 of the main structure 1. The guide rail frame 22 is fixed to the main structure 1 by a wall-mounted frame 23. One or two cages 21 are installed on the guide rail frame 22. The cages 21 are driven by a drive mechanism to move up and down on the guide rail frame 22.

[0062] This invention addresses the safety issues arising from the use of a temporary connecting platform 3 during the operation of existing construction elevators 2.

[0063] In contrast, the present invention proposes a connection platform 3 for construction elevator 2 and main structure 1, including: a tilting platform 31, a tilting collection bucket 32, a sensing structure 33, a second sensor 35, and a controller 36 for controlling the operation of the connection platform 3.

[0064] like Figures 5-8 As shown, the flipping platform 31 is configured as a foldable structure, including a mounting frame 31a fixedly installed on the wall 11 at the opening 12 of the main structure 1; and a flipping frame 31b hinged together with the mounting frame 31a. A textured pedal 31c is installed on the top of the flipping frame 31b, and a first telescopic rod 31d for driving the flipping frame 31b to rotate is hinged between the mounting frame 31a and the flipping frame 31b.

[0065] like Figures 5-6 As shown, in the working state (at this time, the platform 3 can be connected to the construction elevator 2 and the main structure 1 for transporting materials or personnel passage), the controller 36 controls the tilting frame 31b to be in a horizontal state. At this time, the controller 36 controls the tilting collection bucket 32 ​​to fold to the bottom of the tilting frame 31b.

[0066] The current working mode is:

[0067] Mode 1

[0068] After the controller 36 controls the first telescopic rod 31d to extend fully, it closes the first telescopic rod 31d; and the controller 36 controls the second telescopic rod 32c to retract fully, closing the second telescopic rod 32c.

[0069] At this time, the first telescopic rod 31d unfolds the tilting frame 31b to be perpendicular to the mounting frame 31a; the second telescopic rod 32c folds the tilting collection bucket 32 ​​to the bottom of the tilting frame 31b.

[0070] like Figures 7-8 As shown, in the non-working state (when the construction elevator 2 runs to the upper or lower floor of the main structure 1, away from the current opening 12), the controller 36 controls the tilting frame 31b to be in an inclined state. At this time, the controller 36 controls the tilting collection bucket 32 ​​to unfold to the outside of the tilting frame 31b.

[0071] The current working mode is:

[0072] Mode 2

[0073] After the controller 36 controls the first telescopic rod 31d to retract completely, the first telescopic rod 31d is closed; and the controller 36 controls the second telescopic rod 32c to extend completely, and the second telescopic rod 32c is closed.

[0074] At this time, the first telescopic rod 31d folds the tilting frame 31b, and the tilting frame 31b is in an inclined state; the second telescopic rod 32c unfolds the tilting collection bucket 32 ​​to the outside of the tilting frame 31b.

[0075] like Figure 10 As shown, the signal input terminal of the controller 36 is communicatively connected to the signal output terminals of the first sensor 33b, the second sensor 35, and the construction elevator 2, respectively. The signal output terminal of the controller 36 is communicatively connected to the signal output terminals of the first telescopic rod 31d, the second telescopic rod 32c, the negative pressure generator 34b, and the construction elevator 2, respectively.

[0076] The controller 36 is communicatively connected to the control circuit of the construction elevator 2, and is used to receive the current operating status information of the construction elevator 2; and to output prompt information to the construction elevator 2 for prompting.

[0077] The triggering conditions for the operation of Mode 1 and Mode 2 are: based on the state of construction elevator 2.

[0078] like Figures 2-4 In this regard, a sensing structure 33 is provided, which is installed on the mounting frame 31a to sense the state of the connection between the construction elevator 2 cage 21 and the tilting platform 31.

[0079] The sensing structure 33 includes a bracket 33a and a first sensor 33b. Extension rods are provided on both sides of the mounting frame 31a. The bracket 33a is mounted on the extension rods, and the first sensor 33b is mounted on the bracket 33a. The first sensor 33b is a grating sensor used to sense whether there is an obstacle at the connection between the construction elevator 2 cage 21 and the tilting platform 31; and to sense the position of the connection between the cage 21 and the tilting platform 31.

[0080] The first sensor 33b detects information at the connection between the construction elevator 2 cage 21 and the tilting platform 31. A second sensor 35 is also provided, which is installed on the wall-mounted frame 23 of the construction elevator 2 to sense the position of the cage 21. When the cage 21 is sensed to be at the opening 12 of the main structure 1, the first sensor 33b is triggered to perform real-time detection. At the same time, the controller 36 also determines whether the construction elevator 2 is stopped at the opening 12 of the current floor based on the operating status of the construction elevator 2.

[0081] Based on the signal detected by the first sensor 33b and the operating status of the construction elevator 2, either mode one or mode two is activated respectively.

[0082] like Figures 5-8As shown, a flipping collection bucket 32 ​​is provided at the bottom of the flipping frame 31b, including a lifting lug 32a that is hinged to the flipping frame 31b. The lifting lug 32a is connected to the bucket body 32b. A second telescopic rod 32c is provided between the lifting lug 32a and the flipping frame 31b on the side away from the flipping frame 31b. The two ends of the second telescopic rod 32c are respectively hinged to the flipping frame 31b and the lifting lug 32a.

[0083] In operation, the controller 36 controls the second telescopic rod 32c to fully retract, and the second telescopic rod 32c folds the flipping collection bucket 32 ​​to the bottom of the flipping frame 31b.

[0084] In the non-working state, the controller 36 controls the second telescopic rod 32c to extend fully, and the second telescopic rod 32c unfolds the tilting collection bucket 32 ​​to the outside of the tilting frame 31b.

[0085] When the rotating collection bucket 32 ​​is unfolded to the outside of the rotating frame 31b in the non-working state, the rotating frame 31b is tilted toward the rotating collection bucket 32. Construction waste, small stones, dust, debris and other debris scattered on the mesh pedal 31c of the rotating frame 31b fall into the interior of the rotating collection bucket 32 ​​along the mesh pedal 31c.

[0086] The width of the flip-over collection bucket 32 ​​is greater than the width of the mesh pedal 31c, which is conducive to the complete collection of construction waste, small stones, dust, debris and other debris scattered on the mesh pedal 31c.

[0087] like Figures 1-4 As shown in Figure 9, in order to achieve the effect of automatic collection, a collector 34 is also provided. The collector 34 is connected to one side of the bucket body 32b through the collection pipe 34a. The collector 34 has a negative pressure generator 34b and a collection box 34c inside. The side wall of the collection box 34c has a perforated structure. A filter screen 34d is provided between the collection box 34c and the negative pressure generator 34b. The collection pipe 34a is connected to the collection box 34c. After the negative pressure generator 34b is started, a negative pressure environment is formed inside the collector 34. The signal input terminal of the negative pressure generator 34b is communicatively connected to the signal output terminal of the controller 36.

[0088] One collector 34 can be connected to at least one tilting collection bucket 32. In order to facilitate the collection of construction waste, small stones, dust, debris and other debris inside the tilting collection bucket 32 ​​by the collector 34, the inside of the bucket body 32b of the tilting collection bucket 32 ​​is set in an inclined state, with the tilt direction facing the connection of the collection pipe 34a of the collector 34. Construction waste, small stones, dust, debris and other debris scattered on the mesh pedal 31c fall along the mesh pedal 31c into the inside of the tilting collection bucket 32 ​​and slide down to the connection of the collection pipe 34a under the action of gravity. This facilitates the suction of construction waste, small stones, dust, debris and other debris into the collection box 34c after the negative pressure generator 34b is started.

[0089] The aforementioned collection box 34c adopts a detachable structure, including a box body with a perforated structure on its side wall, a box cover, and a box body connected by a threaded connection or a plug-in connection. The collection box 34c is connected to the collector 34 by a plug-in connection. After the collection box 34c is inserted into the collector 34, a sealed structure is formed, and the external airflow can only flow into the collector 34 through the collection pipe 34a. The negative pressure generator 34b is a vacuum pump.

[0090] like Figure 11 As shown, a method for operating a connection platform between a construction elevator and the main structure includes the following steps:

[0091] S1, the controller 36 collects the signal from the second sensor 35 in real time;

[0092] S2, after the second sensor 35 detects that the cage 21 of the construction elevator 2 has moved to the opening 12 on the first floor of the main structure, the first sensor 33b is activated.

[0093] S3, the first sensor 33b collects information at the connection point between the construction elevator 2 cage 21 and the tilting platform 31;

[0094] S4, when the controller 36 determines that there is no abnormality at the connection point and the construction elevator 2 stops at the opening 12 of the current floor, the controller 36 controls the first telescopic rod 31d to fully extend and then closes the first telescopic rod 31d; and the controller 36 controls the second telescopic rod 32c to fully retract and then closes the second telescopic rod 32c.

[0095] S5, when the controller 36 determines that there is an abnormality at the connection point, the controller 36 sends a prompt message to the construction elevator 2;

[0096] S6, after the second sensor 35 no longer detects the cage 21 of the construction elevator 2, after a first set time, the controller 36 controls the first telescopic rod 31d to fully retract and closes the first telescopic rod 31d; and the controller 36 controls the second telescopic rod 32c to fully extend and closes the second telescopic rod 32c.

[0097] S7, the controller 36 turns on the negative pressure generator 34b to generate a negative pressure environment in the collector 34;

[0098] S8, through the collection pipe 34a, the debris in the bucket 32b is sucked into the collection box 34c;

[0099] S9, after the second set time has elapsed, the controller 36 shuts off the negative pressure generator 34b;

[0100] S10, repeat steps S1~S9 above.

[0101] The first and second set times are user-defined times. The first set time is used to ensure that the construction elevator 2 leaves the opening 12 of the current floor, and the second set time is used to ensure that the construction waste, pebbles, dust, debris and other debris in the flipping collection bucket 32 ​​are completely collected.

[0102] This invention provides a connection platform 3 between a construction elevator 2 and a main structure 1 and its working method. It adopts an inductive flipping structure and a foreign object collection structure, which effectively solves the safety problems existing in the current temporary structure.

[0103] It should be noted that the specific models and specifications of the controller 36, the first sensor 33b, the second sensor 35, the first telescopic rod 31d, the second telescopic rod 32c, and the negative pressure generator 34b 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.

[0104] The power supply and operating principle of the controller 36, the first sensor 33b, the second sensor 35, the first telescopic rod 31d, the second telescopic rod 32c, and the negative pressure generator 34b are clear to those skilled in the art and will not be described in detail here.

[0105] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
