Description

Technical Field

[0002] In the prior art, the protective net for construction is usually fixed on the wall of the building through a support frame arranged on the wall. As the construction progresses of the main building, the protective net is lifted up layer by layer to the floor under construction.

[0003] When lifting the protective net layer by layer, multiple electric hoists are usually used to pull the protective net upward as a whole until it reaches a predetermined height. Since the electric hoists are operated manually, it is impossible to keep the climbing speed of each electric hoist consistent during lifting, which will make the overall climbing speed of the protective net slow and unstable. Generally, it takes one or several days to complete the climbing, and the construction time is long. In addition, this climbing method can only climb upwards but cannot descend downwards. After the construction is completed, the protective net that has climbed to the top floor of the building needs to be manually dismantled, which makes the construction difficult and the construction cost increases accordingly.

[0052] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described 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, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0053] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0054] Reference Figure 1 to Figure 15 As shown, the embodiment of the present invention discloses an attached automatic lifting operation safety protection platform for construction, which mainly includes:

[0055] A lifting column 100 is arranged on the outside of a building wall 500 in a vertical direction;

[0056] The electric attachment mechanism comprises three rows of fixed electric attachment supports 200 and two movable electric attachment supports 200 which are arranged at equal intervals along the height direction of the lifting column 100; each row of fixed electric attachment supports 200 comprises two electric attachment supports 200 which are fixed and symmetrically arranged on both sides of the lifting column 100, and the two movable electric attachment supports 200 can move in the vertical direction, and each movable electric attachment support 200 can be located in the middle of two electric attachment supports 200 in one row of fixed electric attachment supports 200 when moving in the vertical direction; the spacing between each movable electric attachment support 200 is the same as the spacing between each row of fixed electric attachment supports 200;

[0057] A plurality of embedded parts 300 are arranged in a building wall 500 at equal intervals and are adapted to the electric attachment mechanism so that the electric attachment support 200 in the electric attachment mechanism can be inserted into and locked accordingly;

[0058] The main frame 400 is vertically arranged on the lifting column 100 and is located at a side away from the building wall 500 . A scaffolding board is arranged on the main frame 400 .

[0059] In this embodiment, in order to facilitate the climbing or descending of the protection net, each time the protection net climbs or descends, it corresponds to climbing one floor of the main building. Therefore, when the safety protection platform described in the embodiment of the present invention is used, the main building needs to be built to the third floor or above. The attached automatic lifting safety protection platform for construction can be attached and fixed on the wall of the building, and can load the entire protection net to climb upward or descend on the outer wall of the building.

[0060] The lifting column is arranged on the outside of the building wall in the vertical direction, and a main frame for setting up a protective net is installed behind it, and the main frame is also arranged in the vertical direction. In practical applications, in order to form an integral protective net on the outer wall of the building, it is generally necessary to arrange multiple lifting columns side by side to cover the entire building wall horizontally, and at the same time, the same number of main frames are arranged on each lifting column, and the spacing between each lifting column is usually set to 2 to 5 meters. Generally, the floor height of the main building is 3 meters, and the height of the entire lifting column is about 6.3 meters.

[0061] Scaffolding boards are laid between each main frame to form a three-layer scaffolding, and a safety mesh is set on the outside of the scaffolding to form a protective net. The main frame has upward and downward extending parts at the top and bottom of the lifting column, so that the construction floor can be covered as comprehensively as possible.

[0062] Correspondingly, an electric attachment mechanism is arranged on the side of the lifting column opposite to the building wall, and the electric attachment mechanism includes three rows of fixed electric attachment supports and two movable electric attachment supports arranged at equal intervals along the height direction of the lifting column. By alternately climbing or descending the three rows of fixed electric attachment supports and the two movable electric attachment supports, the purpose of the protective net climbing one floor of the building main body each time it climbs or descends can be achieved.

[0063] Among them, three rows of fixed electric attachment supports are arranged at equal intervals along the height direction of the lifting column, and each row of fixed electric attachment supports includes two electric attachment supports that are fixed and symmetrically arranged on both sides of the lifting column; two movable electric attachment supports are arranged on the lifting column at equal intervals along the height direction of the lifting column and can move in the vertical direction, and each movable electric attachment support can be located in the middle of two electric attachment supports in one row of fixed electric attachment supports when moving in the vertical direction. In the specific arrangement, the three rows of fixed electric attachment supports are respectively arranged at the top, middle and bottom positions of the lifting column.

[0064] In addition, the spacing between the movable electric attachment supports is the same as the spacing between the fixed electric attachment supports in each row, so that the movable electric attachment supports can be on the same horizontal plane as the two fixed electric attachment supports in one row and symmetrically arranged on both sides of the lifting column when moving in the vertical direction. In the specific setting, the spacing between the three rows of fixed electric attachment supports and the spacing between the two movable electric attachment supports is the same as the floor height of the building, which is generally about 3 meters.

[0065] A plurality of embedded parts respectively adapted to the electric attachment mechanism are also arranged on the wall of the building, and are arranged at equal intervals in the vertical direction to form a row, so that the electric attachment support in the electric attachment mechanism can be inserted and locked accordingly. Each embedded part is usually arranged at a position close to the top floor of each floor, and the spacing between them is the same as the spacing between each row of fixed electric attachment supports or two movable electric attachment supports. The electric attachment supports in a row on the lifting column can automatically extend into the corresponding embedded parts and be locked, so that the protective net on the lifting column is attached to the wall of the building as a whole. In specific implementation, the number of columns of embedded parts is the same as the number of lifting columns, and the number of embedded parts set in each column is the same as the total number of floors of the building.

[0066] Initially, the two movable electric attachment supports on the lifting column are respectively dropped vertically to the middle and bottom positions of the lifting column, and together with the two rows of fixed electric attachment supports at the middle and bottom positions of the lifting column, they are automatically extended into the corresponding embedded parts on the building wall and locked, while the row of fixed electric attachment supports at the top position of the lifting column is automatically extended into the corresponding embedded parts on the building wall and locked, so that the protective net on the lifting column is attached to the building wall as a whole. Figure 1 and Figure 2 As shown, Figure 1 and Figure 2 The diagram shows the state of the attached automatic lifting safety protection platform for construction according to the embodiment of the present invention when it is attached to the wall of a building in the initial position.

[0067] After a new floor of the building is constructed, the protective net needs to be raised up one floor as a whole. At this time, the two movable electric attachment supports on each lifting column automatically retract to separate them from the connection with the embedded parts, and then they are driven by the lifting column to rise in the vertical direction to the middle and top positions of the lifting column, that is, they rise to the embedded parts corresponding to the previous floor respectively. Then, the two movable electric attachment supports automatically open and extend into the embedded parts of the two rows of fixed electric attachment supports at the middle and top positions on the lifting column and lock them. After that, the three rows of fixed electric attachment supports on each lifting column automatically retract to separate them from the connection with the embedded parts, and then they are driven by the lifting column to rise in the vertical direction to the embedded parts corresponding to the previous floor respectively. Then, the three rows of fixed electric attachment supports automatically open and extend into the embedded parts corresponding to the previous floor and lock them, completing the process of the protective net climbing up one floor as a whole. Figure 3 and Figure 4 As shown, Figure 3 and Figure 4 The diagram shows the state of the attached automatic lifting safety protection platform for construction according to the embodiment of the present invention after it is attached to the wall of a building and climbs up one floor.

[0068] When the overall construction of the building is completed, the protective net can be lowered layer by layer until it reaches the lowest floor, which is convenient for removal. The specific process of the overall lowering of the protective net is opposite to the above-mentioned climbing process, so it can be implemented with reference to the above-mentioned climbing process and will not be repeated here.

[0069] When the protective net is climbing or descending as a whole, each lifting column needs to maintain synchronous movement, so that the protective net as a whole can be automatically, smoothly and quickly attached and lifted.

[0070] It should be noted that those skilled in the art can also set other rows of fixed electric attachment supports and a corresponding number of movable electric attachment supports on the lifting columns according to actual usage requirements, and set the corresponding number of embedded parts at the same time, which can also achieve the purpose of climbing or descending the protective net on the wall of the building. The specific setting method will not be repeated here.

[0071] In summary, under the joint action of the lifting column, electric attachment supports and embedded parts, the entire protective net can be attached to the wall of the building; at the same time, the electric attachment supports and embedded parts can quickly realize connection and disconnection with the wall of the building, and then utilize the lifting and lowering of the lifting column, and the alternating climbing and descending of the three rows of fixed electric attachment supports and the two movable electric attachment supports on the lifting column to realize the overall climbing and descending of the protective net. The climbing and descending speed is fast and stable, overcoming the defects of constantly dismantling the support frame and then rebuilding it, thereby saving construction time, saving construction costs, and reducing construction difficulty. It has high safety and convenient construction operation.

[0072] Based on the above embodiments, in a specific implementation scheme, specifically refer to Figures 5 to 10 As shown, the lifting column 100 mainly includes:

[0073] The steel seat 101 is a columnar structure with a C-shaped cross section and has a notch 1011 arranged along the height direction;

[0074] The screw rod 102 is arranged in the steel seat 101 and close to the side of the slot 1011. A driving motor 103 is arranged on the top of the screw rod 102 to drive the screw rod 102 to rotate. Two movable attachment supports extending out of the steel seat 101 are arranged on the screw rod 102 at equal intervals along its height direction.

[0075] A first slide rail 104 is disposed in the steel seat 101 and at a side away from the notch 1011 , and the first slide rail 104 is fixedly connected to the steel seat 101 ;

[0076] A plurality of first slides 105 are disposed in the steel seat 101 and fixedly connected to the screw rod 102 at equal intervals along the height direction of the screw rod 102 . The first slides 105 are also connected to the first slide rails 104 in a snap-fit ​​manner.

[0077] In this embodiment, the lifting column includes a steel base of a column structure, whose cross section is C-shaped and one side of which has a notch along the height direction. The steel base can be made of square steel with a hollow interior and a wall thickness of 5 mm, and a notch can be opened on one side of the steel base along the height direction.

[0078] A screw rod is arranged in the steel seat, and a driving motor is arranged on the top of the screw rod, so that the screw rod can rotate under the drive of the driving motor. Therefore, after two movable electric attachment supports are further arranged on the screw rod at equal intervals along its height direction, the two movable electric attachment supports can extend out of the steel seat from the notch of the steel seat and move up and down in the vertical direction following the rotation of the screw rod.

[0079] Similarly, after further arranging three rows of fixed electric attachment supports symmetrically and evenly spaced on both sides of the outside of the steel base, since the spacing between the two movable electric attachment supports is the same as the spacing between the three rows of fixed electric attachment supports, the movable electric attachment support can be located on the same horizontal plane with the two fixed electric attachment supports in one of the rows when moving in the vertical direction.

[0080] When the protective net needs to be lifted up by one floor as a whole, the driving motor rotates forward to make the screw rod rotate forward, driving the two movable electric attachment supports to move upward in the vertical direction, so that the two movable electric attachment supports rise from the bottom and middle positions of the lifting column to the middle and top positions of the lifting column, that is, rise to the embedded parts corresponding to the previous floor respectively, and the two movable electric attachment supports automatically open and extend into the embedded parts corresponding to the previous floor and lock. Afterwards, the driving motor reverses to make the screw rod rotate in the opposite direction, driving the two movable electric attachment supports to move downward in the vertical direction, so that the two movable electric attachment supports fall from the top and middle positions of the lifting column to the middle and bottom positions of the lifting column respectively.

[0081] Since the two movable electric attachment supports are always locked by the embedded parts during this process, when the two movable electric attachment supports move downward in the vertical direction, the steel seat will drive the three rows of fixed electric attachment supports installed on it to rise in the opposite direction. When rising, the three rows of fixed electric attachment supports will automatically shrink to break away from the connection with the embedded parts, and then they will rise vertically to the embedded parts corresponding to the upper floor respectively under the drive of the steel seat, and then the three rows of fixed electric attachment supports will automatically open and extend into the embedded parts corresponding to the upper floor and lock, thus completing the process of the overall protective net climbing up one floor.

[0082] A slide rail and a plurality of slides are also provided in the steel seat, wherein the slide rail is equal in length to the steel seat, and its upper and lower ends are flush with the upper and lower ends of the steel seat, and the slide rail is fixed to the side of the steel seat away from the notch by bolts. The plurality of slides are fixedly connected to the screw rod at equal intervals along the height direction of the screw rod, and are connected to the slide rail in a snap-fit ​​manner, so that each slide can move in the vertical direction along the slide rail when the screw rod rotates.

[0083] Since the bottom of the screw rod is not connected to the steel seat, when the screw rod rotates under the drive of the driving motor, the screw rod can be positioned in the vertical direction by arranging multiple slides on the screw rod that can move in the vertical direction along the slide rails to prevent it from shifting during rotation. This ensures that the two movable electric attachment supports arranged on the screw rod can accurately extend into the corresponding embedded parts and be locked.

[0084] In addition, an electrical control cabinet is provided on the scaffolding board laid on the main frame, and the electrical control cabinet is connected to the drive motor signal to control the drive motor. When the protective net is climbing or descending as a whole, the electrical control cabinet uniformly controls the drive motors on each lifting column, so that each lifting column maintains synchronous movement, so that the protective net as a whole can automatically, smoothly and quickly perform an attached lifting operation. Preferably, the electrical control cabinet is a PLC control cabinet.

[0085] Preferably, specific reference is made to Figures 5 to 9 As shown, a plurality of connecting fasteners 110 are provided along the height direction of the outer side of the steel seat 101 opposite to the notch 1011 to connect to the main frame 400 .

[0086] Specifically, a plurality of connecting fasteners are arranged along the height direction of the back of the steel base, and the connecting fasteners are used to install the main frame. The connecting fasteners include two parts, one part is fixedly arranged on the steel base, and the other part is connected to the part by bolts. After the two parts are connected, a hollow structure that can accommodate the frame of the main frame is formed in the middle. This arrangement facilitates the connection and removal of the main frame.

[0087] Based on the above embodiments, in a specific implementation scheme, specifically refer to Figures 5 to 10 and Fig.11 As shown, two fixing components 106 are arranged on the screw rod 102 at equal intervals along its height direction, and the fixing component 106 includes a screw nut 1061 and a guide seat 1062. The screw nut 1061 is sleeved on the screw rod 102, and the guide seat 1062 is sleeved on the screw nut 1061; one end of the guide seat 1062 sleeved on the screw nut 1061 is fixedly connected to the first slide 105, and the other end thereof extends outward from the slot 1011 to the outside of the steel seat 101 to connect to the movably arranged electric attachment support 200.

[0088] In this embodiment, two fixing components are arranged on the screw rod at equal intervals along its height direction, and the fixing components further include a screw rod nut and a guide seat. The screw rod nut is generally a copper nut, which is directly sleeved on the screw rod, and the guide seat is further sleeved on the screw rod nut.

[0089] Furthermore, one end of the guide seat sleeve on the screw nut is fixedly connected to the slide, and the other end thereof extends outward from the groove of the steel seat to the outside of the steel seat, and the other end thereof is used to connect to a movably arranged electric attachment support, so that the movably arranged electric attachment support can move in the vertical direction following the screw.

[0090] During specific implementation, the number of slides provided is the same as the number of fixed components provided, which is also two.

[0091] Preferably, specific reference is made to Fig.11As shown, the guide seat 1062 is an irregular part, which includes a screw connecting part 1062-1, an extension part 1062-2 and a support connecting part 1062-3, and the support connecting part 1062-3 is connected to the screw connecting part 1062-1 through the extension part 1062-2; the screw connecting part 1062-1 is a columnar structure with a through hole opened along its height direction, which is sleeved on the screw nut 1061; the extension part 1062-2 and the support connecting part 1062-3 are both rectangular structures, and the extension part 1062-2 and the support connecting part 1062-3 are arranged perpendicular to each other so that the side with the largest area of ​​the support connecting part 1062-3 is opposite to the screw connecting part 1062-1.

[0092] Specifically, the screw rod connection part is a columnar structure with a through hole opened along its height direction, which is sleeved on the screw rod nut. The extension part and the support connection part are both rectangular parallelepiped structures, and the extension part and the support connection part are arranged perpendicularly to each other so that the side of the support connection part with the largest area is opposite to the screw rod connection part. The support connection part extends outward from the notch of the steel seat to the outside of the steel seat to connect with the movable electric attachment support.

[0093] The guide seat sleeve is arranged on one end of the screw nut, i.e. the screw connecting part, which is fixedly connected with the slide. Generally, the height of the slide is the same as the height of the screw connecting part.

[0094] Further preferably, a plurality of rows of column mounting holes 1062 - 4 are arranged in parallel along the height direction on the support connecting portion 1062 - 3 in the guide seat 1062 , and the electric attachment support 200 is connected through the column mounting holes 1062 - 4 .

[0095] Specifically, a plurality of rows of column mounting holes are arranged in parallel along the height direction on the support connecting portion of the guide seat, and a movably arranged electric attachment support is connected through the column mounting holes.

[0096] Correspondingly, a plurality of rows of support mounting holes are also arranged in parallel on the movable electric attachment support, so that when the movable electric attachment support is installed on the guide seat, the installation position of the electric attachment support can be appropriately adjusted according to the actual position of the embedded parts, and one of the rows of support mounting holes on the electric attachment support can be selected to be aligned with one of the rows of column mounting holes on the support connecting part of the guide seat, and then the electric attachment support is installed on the guide seat through bolt connection, and then it is arranged on the screw rod to form a movable electric attachment support, and the movable electric attachment support can move in the vertical direction along the screw rod, while ensuring that the electric attachment support can extend into the corresponding embedded part and be locked.

[0097] Based on the above embodiments, in a specific implementation scheme, specifically refer to Figures 5 to 9As shown, a coupling 108 and a reducer 109 are also provided on the top of the screw rod 102. The coupling 108 is arranged above the screw rod 102 and connected to the top of the screw rod 102. The reducer 109 is arranged above the coupling 108 and connected to the coupling 108. The drive motor 103 is arranged above the reducer 109 and connected to the reducer 109.

[0098] In this embodiment, a coupling and a reducer are further arranged on the top of the screw rod. The reducer is connected to the drive motor, which can slow down the rotation speed output by the drive motor to the screw rod, so that the screw rod can rotate more smoothly, thereby making the overall rise or fall of the protective net more stable.

[0099] A coupling is also connected between the reducer and the screw rod, which rotates together in the process of transmitting the motion and power output by the reducer to the screw rod, and is used to connect the output shaft of the reducer and the screw rod. At the same time, it can also be used to prevent the connected mechanism from bearing excessive loads, playing the role of overload protection.

[0100] In addition, the reducer is also connected to the electrical control cabinet signal to accept the control of the electrical control cabinet. When the protective net is climbing or descending as a whole, the electrical control cabinet also uniformly controls the reducers on each lifting column, so that each lifting column maintains synchronous movement, so that the protective net as a whole can automatically, smoothly and quickly attach and lift.

[0101] Based on the above embodiments, in a specific implementation scheme, specifically refer to Figures 5 to 9 As shown, a plurality of rows of anti-falling grooves 1012 are arranged in parallel on the steel seat 101 along its height direction, and each row of anti-falling grooves 1012 includes two anti-falling grooves 1012 symmetrically arranged on both sides of the notch 101 .

[0102] In this embodiment, a plurality of rows of anti-falling grooves are further arranged on one side of the steel seat having the notch, wherein each row of anti-falling grooves includes two anti-falling grooves symmetrically arranged on both sides of the notch.

[0103] The anti-fall device adapted to the anti-fall groove can be pre-fixed on the wall of the building, or can be set on two movable electric attachment supports and move together in the vertical direction. One end of the anti-fall device is fixed on the wall of the building or on the movable electric attachment support, and the other end can be abutted on the anti-fall groove, which can effectively prevent the lifting column from accidentally falling during the ascent or descent process. The anti-fall device adopts the anti-fall structure in the prior art, and its structure is not described here.

[0104] Based on the above embodiments, in a specific implementation scheme, specifically refer to Figures 5 to 10 and Fig.12 and Fig.13The electric attachment support 200 includes an attachment support motor 201, a support base 202 and a movable claw base 203. A support screw 2021 is arranged in the support base 202. The support screw 2021 is connected to the attachment support motor 201 arranged at one end of the support base 202 and rotates by the drive of the attachment support motor 201. When the support screw 2021 rotates, the movable claw base 203 sleeved on the other end of the support base 202 slides along the support base 202.

[0105] Two upwardly and downwardly symmetrical sliding claws 2031 are arranged in the movable claw seat 203, one end of the sliding claw 2031 is fixed, and the other end of the sliding claw 2031 has a protrusion 2031-1 protruding toward the outside of the movable claw seat 203. When the movable claw seat 203 slides along the support seat 202, the two protrusions 2031-1 extend or retract from the openings 2032 arranged on the upper and lower sides of the movable claw seat 203 respectively.

[0106] In this embodiment, the fixed electric attachment support and the movable electric attachment support can adopt the same structure, and the electric attachment support mainly includes an attachment support motor, a support seat and a movable claw seat. The support seat is a rectangular structure, which is arranged horizontally along its length direction and is used to connect with the lifting column. The attachment support motor is arranged at one end of the support seat, and the movable claw seat is sleeved at the other end.

[0107] A support screw is arranged in the support seat, which is connected to an attachment support motor arranged at one end of the support seat and rotates by the drive of the attachment support motor. When the support screw rotates, the movable claw seat sleeved at the other end of the support seat slides along the support seat.

[0108] In addition, two sliding claws symmetrically arranged in the movable claw seat are arranged, wherein one end of the two sliding claws is fixed, and the other end thereof has a protrusion protruding toward the outside of the movable claw seat. When the movable claw seat slides along the support seat, the two protrusions are respectively extended or retracted from the openings arranged on the upper and lower sides of the movable claw seat. Specifically, when the movable claw seat slides along the support seat toward the end where the attachment support motor is arranged, the two protrusions are respectively retracted from the openings arranged on the upper and lower sides of the movable claw seat; when the movable claw seat slides along the support seat toward the opposite direction of the end where the attachment support motor is arranged, the two protrusions are respectively extended from the openings arranged on the upper and lower sides of the movable claw seat.

[0109] The embedded part matched with the electric attachment support is arranged on the wall of the building. It has an opening for the electric attachment support to extend into, and its upper and lower bottom surfaces respectively have positioning grooves that can accommodate the protrusion on the sliding claw, so that when the electric attachment support is extended into and locked in the embedded part, the protrusion can be fixed in the positioning groove.

[0110] Therefore, when the electric attachment support needs to be extended into the corresponding embedded part and locked, the support screw rotates under the drive of the attachment support motor, thereby driving the movable claw seat sleeved on the other end of the support seat to slide along the support seat in the opposite direction of the end where the attachment support motor is provided, and then the two protrusions extend from the openings provided on the upper and lower sides of the movable claw seat respectively.

[0111] At this time, the movable claw seat on the electric attachment support extends from the opening of the embedded part. When the protrusions on the two sliding claws extend from the openings arranged on the upper and lower sides of the movable claw seat respectively, they can just extend into the positioning grooves provided on the upper and lower bottom surfaces of the embedded part and be fixed in the positioning grooves, so that the lifting column and the protective net arranged on the lifting column are attached to the wall of the building as a whole.

[0112] When the lifting column moves upward, it drives each electric attachment support to move upward as a whole. At this time, the attachment support motor drives the support screw to rotate, so that the movable claw seat sleeved on the other end of the support seat slides along the support seat toward the end where the attachment support motor is set, so that the protrusions on the two sliding claws are retracted from the openings set on the upper and lower sides of the movable claw seat, thereby completing the contraction of the electric attachment support.

[0113] When each electric attachment support reaches the corresponding embedded part, the attachment support motor drives the support screw to rotate, so that the movable claw seat sleeved on the other end of the support seat slides along the support seat in the opposite direction of the end where the attachment support motor is set, so that the protrusions on the two sliding claws extend from the openings set on the upper and lower sides of the movable claw seat respectively, and then further extend into the positioning grooves on the upper and lower bottom surfaces of the embedded part, and are fixed in the positioning grooves.

[0114] Each electric attachment support and embedded parts cooperate with the lifting column, so that the protective net can be attached to the wall of the building as a whole, and can quickly connect and disconnect with the building wall, and can well cooperate with the rise and fall of the lifting column, and finally realize the automatic, stable and fast attachment lifting operation of the protective net as a whole, making the operation process more convenient. At the same time, after adopting the electric attachment support, each electric attachment support does not need to be manually operated by the operator, and the operation is more convenient.

[0115] It should be noted that the attachment support motors in each electric attachment support are also connected to the electrical control cabinet signal to accept the control of the electrical control cabinet. When the protective net is climbing or descending as a whole, the electrical control cabinet uniformly controls the attachment support motors in each electric attachment support, so that each electric attachment support performs its own action, so that the protective net as a whole can automatically, smoothly and quickly perform an attachment-type lifting operation.

[0116] Preferably, a dovetail groove guide rail 2026 is also provided on the outer side of the support seat 202 .

[0117] Specifically, a dovetail groove guide rail is arranged on the outer side of one end of the support base close to the attachment support motor, and three rows of fixedly arranged electric attachment supports can be arranged on the side of the lifting column through the dovetail groove guide rail.

[0118] The dovetail groove screw rod provided in the dovetail groove guide rail can be used to fine-tune the up and down position of each support seat. After the fine-tuning is completed, the slide plate on the dovetail groove guide rail can be locked by the fixing screw on the side of the dovetail groove guide rail to prevent the support seat from moving up and down. The dovetail groove guide rail adopts the structure in the prior art, and its internal specific structure is not repeated here.

[0119] Three rows of fixed dovetail groove guide rails are arranged at equal intervals along the height direction of the outside of the steel base, and the spacing of each row of dovetail groove guide rails is the same as the spacing of each fixed component. In this way, when the movable electric attachment support moves in the vertical direction to the middle position of the two fixed electric attachment supports, it can be side by side with the two fixed electric attachment supports and be located on the same horizontal plane.

[0120] In order to facilitate the climbing or descending of the protective net, the protective net corresponds to climbing one floor of the main building each time it climbs or descends. Therefore, when the lifting column described in the embodiment of the present invention is used for lifting, the main building needs to be built to the third floor or above. Therefore, correspondingly, two fixing components are provided on the screw rod, and three rows of dovetail groove guide rails are provided on the outside of the steel seat, so that three rows of fixed electric attachment supports and two movable electric attachment supports are provided on the side of the lifting column opposite to the building wall. By using the alternating climbing or descending of the three rows of fixed electric attachment supports and the two movable electric attachment supports, the purpose of the protective net corresponding to climbing one floor of the main building each time it climbs or descends can be achieved.

[0121] Of course, those skilled in the art may also set other numbers of fixed electric attachment supports and corresponding movable electric attachment supports on the lifting column according to actual use needs, that is, set other numbers of dovetail groove guide rails and corresponding fixed components.

[0122] Based on the above embodiments, in a specific implementation scheme, focus on Figure 12 to Figure 15 As shown, the upper and lower sides of the support seat 202 are respectively provided with second slide rails 2022, and the upper and lower sides of the movable claw seat 203 near the support screw rod 21 are respectively provided with second slide tables 2033;

[0123] One side of the second slide 2033 is buckled on the second slide rail 2022 and can slide along the second slide rail 2022, and the other side of the second slide 2033 is fixed on the support screw 2021. When the support screw 2021 rotates, the movable claw seat 203 slides along the support seat 202 through the second slide 2033 and the second slide rail 2022.

[0124] In this embodiment, in the electric attachment support, two slide rails are respectively arranged on the upper and lower side surfaces inside the support, and two slide tables are respectively arranged on the upper and lower sides inside the end of the movable claw seat close to the support screw rod. One side of the two slide tables is respectively buckled on the corresponding slide rails and can slide along the slide rails, and the other sides of the two slide tables are respectively fixed on the support screw rod, so that when the support screw rod rotates under the drive of the attachment support motor, the two slide tables can be driven to slide along the slide rails, and then the movable claw seat can slide along the support seat.

[0125] By arranging a slide rail inside the support seat and correspondingly arranging a slide table inside the movable claw seat, the movable claw seat can conveniently slide along the support seat through the slide table and the slide rail when the support screw rod rotates.

[0126] Based on the above embodiments, in a specific implementation scheme, focus on Figure 12 to Figure 15 As shown, an electromagnet 2034, an electromagnetic push rod 2035 and a connecting rod 2036 are also provided in the movable claw seat 203. The electromagnet 2034 is fixed on the movable claw seat 203. One end of the electromagnetic push rod 2035 is sleeved in the electromagnet 2034. The other end of the electromagnetic push rod 2035 is connected to the connecting rod 2036. The two ends of the connecting rod 2036 are respectively connected to one end of the two sliding claws 2031.

[0127] Two pins 2037 are also provided in the movable claw seat 203, and both ends of the pin 2037 are respectively fixed on the movable claw seat 203. The two pins 2037 respectively penetrate the fixed ends of the two sliding claws 2031, so that the other ends of the two sliding claws 2031 can rotate around the pins 2037, and when rotating, the two protrusions 2031-1 are respectively extended or retracted from the openings 2032 on the movable claw seat 203.

[0128] In this embodiment, in the electric attachment support, an electromagnet, an electromagnetic push rod and a connecting rod are also provided at one end of the movable claw seat opposite to the slide table. The electromagnet is fixed on the side wall inside the movable claw seat, one end of the electromagnetic push rod is sleeved in the electromagnet, and the other end of the electromagnetic push rod is connected to the connecting rod, and the upper and lower ends of the connecting rod are respectively connected to one end of the two sliding claws to fix one end of the sliding claws.

[0129] The two sliding claws are also penetrated by pins near this end, and the two ends of the pins are respectively fixed on the side walls of the movable claw seat, so that the other ends of the two sliding claws can rotate around the pins, and when rotating, the two protrusions can be easily extended or retracted from the openings on the movable claw seat.

[0130] The structure is simple and practical, and can conveniently make the protrusions on the two sliding claws extend out of or retract from the openings on the movable claw seat respectively.

[0131] Preferably, focus on Figure 12 to Figure 15 As shown, a first baffle 2024 is provided at one end of the support base 202 on which the attachment support motor 201 is provided, and a second baffle 2025 is provided at the other end of the support base 202 on which the movable claw base 203 is provided; the electromagnet 2034, the electromagnetic push rod 2035, the connecting rod 2036 and the two sliding claws 2031 arranged in the movable claw base 203 are arranged on the outer side of the second baffle 2025, and there is a gap between the electromagnetic push rod 2035 and the second baffle 2025.

[0132] Specifically, two baffles, namely the first baffle and the second baffle, are respectively provided at both ends of the support seat, which can accommodate the support screw rod and the slide rail therein. At the same time, the slide table in the movable claw seat is also accommodated therein, so that the sliding stroke of the sliding claw seat can be limited when it slides along the support seat, so as to match the specifications of the embedded part, so that the protrusions on the two sliding claws can just extend into the positioning grooves on the upper and lower bottom surfaces of the embedded part.

[0133] In addition, when the movable claw seat is sleeved on the other end of the support seat, the slide table arranged inside it is located on the inner side of the second baffle plate, that is, located inside the support seat, while the electromagnet, electromagnetic push rod, connecting rod and two sliding claws arranged inside it are arranged on the outer side of the second baffle plate, that is, located outside the support seat. At the same time, a gap is also provided between the electromagnetic push rod and the second baffle plate.

[0134] Therefore, when the movable claw seat slides along the support seat toward the end where the attachment support motor is provided, that is, when it slides in the opposite direction of the embedded part, the gap between the second baffle and the electromagnetic push rod becomes smaller until the second baffle contacts the electromagnetic push rod and generates thrust, causing the electromagnetic push rod to slide toward the sliding claw. Since the two sliding claws are respectively penetrated by pins near the ends fixed on the connecting rod, when the electromagnetic push rod slides toward the sliding claw, the other ends of the two sliding claws can rotate outward around the pin, and finally the two protrusions extend from the openings on the movable claw seat, and then extend into the positioning grooves on the upper and lower bottom surfaces of the embedded part.

[0135] When the movable claw seat slides along the support seat in the opposite direction to the end of the motor with the attachment support, that is, when it slides in the direction of the embedded part, the gap between the second baffle and the electromagnetic push rod gradually increases, and the second baffle does not contact the electromagnetic push rod, so that the electromagnetic push rod will slide in the direction of the second baffle. Since the two sliding claws are fixed to the connecting rod near one end and are respectively penetrated by pins, when the electromagnetic push rod slides toward the second baffle, the other ends of the two sliding claws can rotate inward around the pin, and finally the two protrusions are retracted from the openings on the movable claw seat, and then they are disengaged from the positioning grooves on the upper and lower bottom surfaces of the embedded part.

[0136] Through the above structure, the protrusion on the sliding claw can be easily extended or retracted from the openings on the upper and lower sides of the movable claw seat, thereby realizing the connection or disconnection between the electric attachment support and the embedded part.

[0137] More preferably, focus on Figure 5 to Figure 15 As shown, the attachment support motor 201 is arranged on the inner side or the outer side of the first baffle 2024 , and the attachment support motor 201 is connected to one end of the support screw rod 2021 through the support coupling 2023 .

[0138] Specifically, the attachment support motor can be arranged on the inner side or the outer side of the first baffle, that is, it can be arranged inside or outside the support base.

[0139] Among them, the three rows of fixed electric attachment supports are directly set on both sides of the lifting column through the dovetail groove guide rail, so the space for its installation is relatively large, so the attachment support motor can be set outside the support base. Fig.12 and Fig.13 That is, the specific structure of this electric attachment support is shown.

[0140] The two movable electric attachment supports are arranged on the lifting column through the connecting assembly, so the space for their installation is limited. When installing, they need to be connected to the connecting assembly through the first baffle. Therefore, the attachment support motor needs to be arranged inside the support base. Fig.14 and Fig.15 That is, the specific structure of this electric attachment support is shown.

[0141] Corresponding to the support mounting holes on the fixed assembly in the aforementioned lifting column, multiple rows of support mounting holes are also arranged in parallel on the movably arranged electric attachment support, and the multiple rows of support mounting holes are arranged on the first baffle, so that when the movably arranged electric attachment support is installed on the guide seat, the installation position of the electric attachment support can be appropriately adjusted according to the actual position of the embedded part, and one of the rows of support mounting holes on the electric attachment support can be selected to be aligned with one of the rows of column mounting holes on the support connecting part of the guide seat, and then the electric attachment support is installed on the guide seat through bolt connection, and then it is arranged on the screw rod to form a movably arranged electric attachment support, and the movably arranged electric attachment support can move in the vertical direction along the screw rod, while ensuring that the electric attachment support can penetrate into the corresponding embedded part and be locked.

[0142] Of course, those skilled in the art can select a suitable setting mode of the attachment support motor according to actual use requirements, and the embodiment of the present invention is not limited to this.

[0143] The attachment support motor is connected to one end of the support screw through the support coupling, thereby driving the support screw to rotate.

[0144] Based on the above embodiments, in a specific implementation scheme, focus on Figure 16 to Figure 18 As shown, the embedded part 300 includes a connecting part 301 and an external hanging part 302 which are connected to each other. The connecting part 301 is arranged inside the building wall 500, and the external hanging part 302 is arranged outside the building wall 500;

[0145] Both the connecting member 301 and the external member 302 are rectangular hollow structures, and the interior of the connecting member 301 is connected to the interior of the external member 302; an opening for the electric attachment support 200 to extend into is provided on the side of the external member 302 away from the connecting member 301, and positioning grooves 3021 for accommodating the protrusion 2031-1 are respectively provided on the upper and lower bottom surfaces.

[0146] In this embodiment, the embedded part is a hollow structure with one end open, which is composed of a connecting part and an external part connected to each other. The connecting part and the external part are both rectangular hollow structures, and the interior of the connecting part is connected to the interior of the external part. An opening for the electric attachment support to extend into is provided on the side of the external part away from the connecting part, and positioning grooves for accommodating the protrusion are provided on the upper and lower bottom surfaces.

[0147] The embedded parts are pre-installed on the wall of the building during the construction of the main structure of the building, and their openings are outwards, so that the electric attachment support can extend in. Specifically, the connecting parts are arranged inside the wall of the building, and the external parts are arranged outside the wall of the building, and the openings on the external parts face the electric attachment support, so that the electric attachment support can extend in.

[0148] In a specific implementation, the four surfaces of the external component connected to the connecting component all extend toward one end of the connecting component and extend into the interior of the connecting component, so that the connection between the external component and the connecting component can be more firmly established.

[0149] The cross section of the positioning groove is set to a shape that matches the protrusion on the electric attachment support, so that when the electric attachment support extends into the embedded part, the positioning groove can completely accommodate the protrusion, so that the embedded part can lock the electric attachment support, and further enable the lifting column to reach the preset load-bearing capacity.

[0150] Specifically, in this embodiment, the cross-section of the positioning groove is set to a rectangle, so that the contact surface between the protrusion and the positioning groove is a vertical surface, so that the protrusion is not easy to slip out of the positioning groove, and the attachment support is easier to be locked by the embedded part, thereby improving safety.

[0151] Based on the above embodiments, in a specific implementation scheme, focus on Figure 16 to Figure 18 As shown, a fixing hole 3011 is provided on the side of the connecting member 301 away from the external hanging member 302; a through-wall bolt 3012 passes through the fixing hole 3011 and the building wall 500 in sequence, so that the embedded member 300 is fastened to the building wall 500, and the tail of the through-wall bolt 3012 passes through the building wall 500 and is fixed by a nut 3013 and a first gasket 3014;

[0152] Second gaskets 3022 are respectively provided on the bottom surfaces of the positioning grooves 3021 , and positioning holes are provided on the second gaskets 3022 ; the fixing bolts 3023 pass through the positioning holes and the protrusions 2031 - 1 in sequence, so that the protrusions 2031 - 1 are fixed in the positioning grooves 3021 .

[0153] In this embodiment, a fixing hole is provided on the side of the connecting member away from the external hanging member, so that the through-wall bolt can pass through the fixing hole and the building wall in sequence, thereby further fastening the entire embedded member to the building wall.

[0154] When the electric attachment support is inserted into the embedded part and locked, the main frame installed behind the lifting column connected to the electric attachment support will be attached to the wall of the building. Since the weight of the lifting column and the main frame is relatively large, the electric attachment support and the embedded part will inevitably receive a downward pulling force. After the embedded part is tightened by the through-wall bolt, the fixing force of the building wall on the embedded part will be increased, making the embedded part less likely to loosen, improving the load-bearing capacity of the embedded part, and improving safety performance.

[0155] At the same time, when the embedded part is fastened to the building wall by a through-wall bolt, the tail of the through-wall bolt passes through the fixing hole on the connecting part and the building wall in turn, and the head thereof is clamped at the connection between the connecting part and the external part. After the tail of the through-wall bolt passes through the building wall, the nut is tightened on the through-wall bolt. A first gasket is also arranged between the nut and the building wall to make the connection more secure. The first gasket is made of a rigid material, which is slightly larger than the size of the fixing hole, and can cover the fixing hole to fix the through-wall bolt.

[0156] In addition, in order to fasten the protrusion on the electric attachment support in the positioning groove, a second gasket is further provided on the bottom surface of each positioning groove, and a positioning hole is also provided on the second gasket. When the protrusion is located in the positioning groove, the fixing bolt is passed through the positioning hole and the protrusion in sequence, so that the protrusion is fixed in the positioning groove. The second gasket is made of a rigid material, which is slightly larger than the size of the positioning groove and can cover the positioning groove to prevent the two sliding claws on the electric attachment support from retracting, further improving the connection firmness between the electric attachment support and the embedded part, thereby improving the overall load-bearing capacity and safety.

[0157] In summary, an embodiment of the present invention provides an attached automatic lifting work safety protection platform for construction, which is achieved by arranging a lifting column with multiple rows of electric attachment supports in the vertical direction, and arranging embedded parts compatible with the electric attachment supports on the building wall opposite to the lifting column, so that when the electric attachment supports are extended into the corresponding embedded parts and locked, the protection net arranged behind the lifting column can be fixed on the building wall; at the same time, the electric attachment supports and the embedded parts can be quickly connected and disconnected from the building wall, and then the lifting and lowering of the lifting column, as well as the alternating climbing and descending of the three rows of fixed electric attachment supports and the two movable electric attachment supports on the lifting column are coordinated to achieve the overall climbing and descending of the protection net.

[0158] The entire platform has a simple structure, and it climbs and descends quickly and smoothly, overcoming defects such as the need to constantly dismantle and rebuild the support frame, thereby saving construction time, saving construction costs, and reducing construction difficulty. It is highly safe and easy to operate.
