Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a connection platform between a construction elevator and a main structure and a working method thereof. Background Art

[0002] In the process of modern construction, in order to meet the needs of vertical transportation during construction, especially in the construction of large factories or high-rise buildings, construction elevators (also known as construction hoists) have become indispensable equipment. These construction elevators are usually installed around the building to efficiently transport personnel and materials. However, in actual operation, there is often a reserved gap between the construction elevator and the main structure of the building. The original intention of this design is to adapt to the deviation of the line during construction, but it also brings challenges in connection and safety.

[0003] At present, in order to fill these gaps and build a connection platform between the construction elevator and the building, some temporary structural materials are generally used on the construction site, such as discarded grid plates, wooden formwork, etc. Although these temporary materials solve the connection problem to a certain extent, their inherent defects cannot be ignored.

[0004] First, due to the poor stability and firmness of these temporary structural materials, they are prone to loosening during construction. Once loose, they may collide with the construction elevator, which may not only damage the structure of the construction elevator, but also cause safety accidents.

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

[0006] What is more serious is that these temporary structures are prone to falling construction waste, pebbles, dust, debris and other debris. These debris may not only interfere with the operation of the construction elevator, but also directly cause harm to the construction workers below, seriously threatening the safety of the construction site.

[0007] Therefore, in response to the above problems, it is necessary to improve and optimize the connection platform between the construction elevator and the main structure of the building to improve its stability, safety and reliability. Summary of the invention

[0008] The embodiment of the present invention provides a connection platform between a construction elevator and a main structure and a working method thereof, which adopts an inductive flipping structure and a foreign matter collection structure to effectively solve the safety problems existing in existing temporary structures.

[0011] The turning platform comprises a mounting frame fixedly mounted on the wall at the opening of the main structure; and a turning frame hingedly connected to the mounting frame, a mesh pedal being mounted on the top of the turning frame, and a first telescopic rod being hingedly connected between the mounting frame and the turning frame for driving the turning frame to rotate;

[0012] The flip collection bucket is arranged at the bottom of the flip frame, and includes a lifting ear hinged to the flip frame, the lifting ear is connected to the bucket body, and a second telescopic rod is arranged between the flip frame and the side of the lifting ear away from the flip frame, wherein the two ends of the second telescopic rod are respectively hinged to the flip frame and the lifting ear;

[0013] The sensing structure is arranged on the mounting frame and is used to sense the state of the connection between the construction elevator cage and the turning platform;

[0014] It also includes a second sensor disposed on the wall frame of the construction elevator for sensing the position of the cage; and a controller, the controller is respectively connected to the first telescopic rod, the second telescopic rod, the sensing structure, the second sensor, and the construction elevator for communication;

[0015] In the working state, the controller controls the flip frame to be in a horizontal state. At this time, the controller controls the flip collection bucket to fold to the bottom of the flip frame. In the non-working state, the controller controls the flip frame to be in an inclined state. At this time, the controller controls the flip collection bucket to unfold to the outside of the flip frame.

[0016] In order to better implement the technical solution of the present invention, the following technical measures are also adopted.

[0017] Furthermore, the flip platform is in an elongated shape as a whole, and the sensing structure includes a bracket and a first sensor. There are extension rods on both sides of the mounting frame, the bracket is mounted on the extension rods, and the first sensor is mounted on the bracket.

[0018] Furthermore, the first sensor is a grating sensor, which is used to sense whether there is an obstacle at the connection between the construction elevator cage and the flip platform; and to sense the position of the connection between the cage and the flip platform. The signal output end of the first sensor is communicatively connected with the signal input end of the controller.

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

[0020] Furthermore, the collector has a negative pressure generator and a collection box inside, the side wall of the collection box has a hole structure, a filter is provided between the collection box and the negative pressure generator, the collection pipe is connected to the collection box, and a negative pressure environment is formed inside the collector after the negative pressure generator is started, and the signal input end of the negative pressure generator is communicatively connected with the signal output end of the controller.

[0022] Mode 1:

[0023] After the controller controls the first telescopic rod to be fully extended, the first telescopic rod is closed; and, the controller controls the second telescopic rod to be fully retracted, the second telescopic rod is closed;

[0024] At this time, the first telescopic rod unfolds the turning frame to be perpendicular to the mounting frame; the second telescopic rod folds the turning collection bucket to the bottom of the turning frame;

[0025] Mode 2:

[0026] After the controller controls the first telescopic rod to be fully retracted, the first telescopic rod is closed; and the controller controls the second telescopic rod to be fully extended, the second telescopic rod is closed;

[0027] At this time, the first telescopic rod folds the turning frame, and the turning frame is in a tilted state; the second telescopic rod unfolds the turning collection bucket to the outside of the turning frame.

[0028] Further, the following steps are included:

[0033] Further, the following steps are included:

[0034] The controller collects the signal of the second sensor in real time;

[0037] Controller startup mode 2;

[0038] The controller turns on the negative pressure generator to generate a negative pressure environment in the collector;

[0039] Through the collection pipe, the debris in the bucket is sucked into the collection box;

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

[0041] Furthermore, when the controller determines that there is an abnormality at the connection, the controller does not start mode 1 and sends a prompt 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 flip platform.

DETAILED DESCRIPTION

[0059] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0060] like Figure 1 As shown, there is an opening 12 on the wall 11 of the main structure 1 for transporting materials and personnel. Currently, when performing vertical transportation, a protective structure 13 is generally set at the opening 12, and one or two openings are reserved as passages.

[0061] The existing construction elevator 2 includes a guide rail frame 22 vertically arranged with the wall 11 of the main structure 1, the guide rail frame 22 is fixed to the main structure 1 through a wall mounting frame 23, one or two cages 21 are arranged on the guide rail frame 22, and the cage 21 is driven by a driving mechanism to move up and down on the guide rail frame 22.

[0062] The present invention is used to solve the safety problem caused by adopting a temporary connection platform 3 during the use of the existing construction elevator 2.

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

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

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

[0066] The working mode at this time is:

[0067] Mode 1

[0068] After the controller 36 controls the first telescopic rod 31d to be fully extended, the first telescopic rod 31d is closed; and the controller 36 controls the second telescopic rod 32c to be fully retracted, and the second telescopic rod 32c is closed;

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

[0070] like Figures 7-8 As shown, in the non-working state (at this time, the construction elevator 2 runs to the upper or lower layer of the main structure 1, away from the current hole 12 position), the controller 36 controls the flip frame 31b to be in a tilted state. At this time, the controller 36 controls the flip collection bucket 32 ​​to expand to the outside of the flip frame 31b.

[0071] The working mode at this time is:

[0072] Mode 2

[0073] After the controller 36 controls the first telescopic rod 31d to be fully retracted, the first telescopic rod 31d is closed; and the controller 36 controls the second telescopic rod 32c to be fully extended, and the second telescopic rod 32c is closed;

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

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

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

[0077] The working triggering conditions of the above-mentioned mode 1 and mode 2 are: triggered according to the state of the construction elevator 2.

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

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

[0080] The first sensor 33b detects information at the connection between the cage 21 of the construction elevator 2 and the turning platform 31. A second sensor 35 is also provided for this purpose. It is arranged on the wall frame 23 of the construction elevator 2 and is used to sense the position of the cage 21. When it is sensed that the cage 21 is in 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 according to the operating status of the construction elevator 2.

[0081] Mode 1 or mode 2 is started according to the signal detected by the first sensor 33b and the operating status of the construction elevator 2.

[0082] like Figures 5 to 8As shown, a tilting collection bucket 32 ​​is provided at the bottom of the tilting frame 31b, including a lifting ear 32a hinged to the tilting frame 31b, the lifting ear 32a is connected to the bucket body 32b, and a second telescopic rod 32c is provided between the side of the lifting ear 32a away from the tilting frame 31b and the tilting frame 31b, wherein both ends of the second telescopic rod 32c are respectively hinged to the tilting frame 31b and the lifting ear 32a.

[0083] In the working state, the controller 36 controls the second telescopic rod 32c to be fully retracted, and the second telescopic rod 32c folds the overturning collection bucket 32 ​​to the bottom of the overturning frame 31b.

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

[0085] In the non-working state, when the flip collection bucket 32 ​​is unfolded to the outside of the flip frame 31b, the flip frame 31b is in a state of being tilted toward the flip collection bucket 32, and construction waste, pebbles, dust, debris and other debris scattered on the mesh pedal 31c of the flip frame 31b fall along the mesh pedal 31c to the inside of the flip collection bucket 32.

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

[0087] like Figures 1 to 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 32b through a collection pipe 34a. A negative pressure generator 34b and a collection box 34c are provided inside the collector 34. The side wall of the collection box 34c has a hole structure. A filter 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 end of the negative pressure generator 34b is communicatively connected with the signal output end of the controller 36.

[0088] Among them, one collector 34 can be connected to at least one flip collection bucket 32. In order to facilitate the collector 34 to collect construction waste, pebbles, dust, debris and other sundries inside the flip collection bucket 32, the bucket body 32b of the flip collection bucket 32 ​​is set to an inclined state, and the inclined direction is toward the connection part of the collection pipe 34a of the collector 34. The construction waste, pebbles, dust, debris and other sundries scattered on the mesh pedal 31c fall along the mesh pedal 31c to the inside of the flip collection bucket 32, and then slide to the connection part of the collection pipe 34a under the action of gravity, which is conducive to sucking the construction waste, pebbles, dust, debris and other sundries into the collection box 34c after the negative pressure generator 34b is started.

[0089] The above-mentioned collection box 34c adopts a detachable structure, including a box body, a side wall of which has a hole structure, and a box cover, which is connected to the box body by threaded connection or plug-in connection. The collection box 34c and the collector 34 are connected by plug-in. After the collection box 34c is inserted into the collector 34, a sealing structure is formed. The external airflow can only flow into the collector 34 through the collection pipe 34a, and the negative pressure generator 34b adopts a vacuum pump.

[0090] like Fig.11 As shown, a working method of a connection platform between a construction elevator and a main structure comprises the following steps:

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

[0092] S2, after the second sensor 35 detects that the cage 21 of the construction elevator 2 runs to the opening 12 of the main structure 1 floor, the first sensor 33b is activated;

[0093] S3, the first sensor 33b collects information about the connection between the cage 21 of the construction elevator 2 and the turning platform 31;

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

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

[0096] S6, after the second sensor 35 fails to detect the cage 21 of the construction elevator 2, after the first set time has passed, the controller 36 controls the first telescopic rod 31d to be fully retracted, and then closes the first telescopic rod 31d; and the controller 36 controls the second telescopic rod 32c to be fully extended, and then 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, the debris in the bucket 32b is sucked into the collection box 34c through the collection pipe 34a;

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

[0100] S10, loop the above steps S1 to S9.

[0101] The first set time and the second set time are times set by oneself. 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 sundries in the flip collection bucket 32 ​​are completely collected.

[0102] The present invention provides a connection platform 3 between a construction elevator 2 and a main structure 1 and a working method thereof, which adopts an inductive flipping structure and a foreign matter collection structure to effectively solve the safety problem existing in the existing 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, and 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 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 herein.

[0105] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
