And a main frame 400 disposed on the elevation column 100 in a vertical direction and located at a side far from the building wall 500, the main frame 400 being provided with a scaffold board.

In this embodiment, in order to facilitate climbing or descending of the protection net, each time the protection net climbs or descends, the protection net corresponds to one floor of the climbing building main body, so when the safety protection platform according to the embodiment of the invention is adopted, the building main body needs to be built to three layers or more. The attached automatic lifting operation safety protection platform for building construction can be attached and fixed on a building wall body, and can integrally climb up or descend on the outer wall surface of the building by loading the integral protection net.

The lifting upright post is arranged on the outer side of the building wall body along the vertical direction, and a main frame for erecting a protective net is arranged behind the lifting upright post and is also arranged along the vertical direction. In practical application, in order to form an integral protective net on a wall outside a building, a plurality of lifting columns are generally required to be arranged side by side to transversely cover the whole building wall, and meanwhile, the same number of main frames are correspondingly arranged on the lifting columns, and the distance between the lifting columns is generally set to be 2-5 meters. Generally, the floor height of the building main body is 3 meters, and the height of the entire lifting column is about 6.3 meters.

Scaffold boards are paved between the main frames to form three layers of scaffolds, and a safety dense mesh net is arranged on the outer side of the scaffold, so that a protective net is formed. The main frame has portions extending upward and downward at the top and bottom of the lifting columns so that the floors to be constructed can be covered as fully as possible.

Correspondingly, an electric attaching mechanism is arranged on one side, opposite to the building wall, of the lifting upright post, and comprises three rows of electric attaching supports which are fixedly arranged and two electric attaching supports which are movably arranged at equal intervals along the height direction of the lifting upright post. The purpose that the protective net climbs on one floor of the building main body correspondingly when climbing or descending each time can be achieved by utilizing three rows of fixedly arranged electric attachment supports and two movably arranged electric attachment supports to climb or descend alternately.

The three rows of electric attaching supports are arranged at equal intervals along the height direction of the lifting upright post, each row of electric attaching supports are respectively provided with two electric attaching supports which are fixed and symmetrically arranged on two sides of the lifting upright post, the two electric attaching supports which are movably arranged are arranged on the lifting upright post at equal intervals along the height direction of the lifting upright post and can move along the vertical direction, and each electric attaching support which is movably arranged can be positioned in the middle of the two electric attaching supports in one row of electric attaching supports which are fixedly arranged when moving along the vertical direction. When specifically setting up, three rows of fixed electronic attached support that set up respectively in the top, middle part and bottom position department of lift stand.

In addition, the distance between the electric attaching supports arranged in each row is the same as that between the electric attaching supports arranged in each row, so that the electric attaching supports arranged in each row can be positioned on the same horizontal plane with the two electric attaching supports which are arranged on two sides of the lifting upright post in one row and are symmetrically arranged when moving along the vertical direction. When the electric adhesion support is specifically arranged, the distance between the three rows of electric adhesion supports which are fixedly arranged and the distance between the two electric adhesion supports which are movably arranged are the same as the floor height of a building, and are generally about 3 meters.

The building wall is also provided with a plurality of embedded parts which are respectively matched with the electric attachment mechanisms, and the embedded parts are arranged at equal intervals along the vertical direction to form a row, so that the electric attachment supports in the electric attachment mechanisms can correspondingly extend into and be locked. The embedded parts are usually arranged at the position of each floor close to the top floor slab, and the distance between the embedded parts is the same as the distance between the electric attaching supports arranged fixedly in each row or the electric attaching supports arranged movably. The electric attaching supports on the lifting upright posts, which are arranged in a row, can automatically extend into the corresponding embedded parts and are locked, so that the protective net on the lifting upright posts is integrally attached to the building wall. In the concrete implementation, the number of columns of embedded parts is the same as the number of lifting columns, and the number of the embedded parts arranged on each column is the same as the total number of floors of a building.

Initially, two electric attaching supports which are movably arranged on the lifting upright post respectively descend to the middle part and the bottom part of the lifting upright post along the vertical direction, and the electric attaching supports which are fixedly arranged on the lifting upright post and positioned at the middle part and the bottom part automatically extend into corresponding embedded parts on a building wall body together with the electric attaching supports which are fixedly arranged on the lifting upright post, and the electric attaching supports which are fixedly arranged on the top part of the lifting upright post automatically extend into corresponding embedded parts on the building wall body and are locked, so that a protective net on the lifting upright post is integrally attached to the building wall body. As shown in fig. 1 and 2, fig. 1 and 2 show a state when the attached automatic lifting operation safety protection platform for building construction according to the embodiment of the invention is attached to an initial position on a building wall.

When a new layer of building is built, the whole protective net needs to climb upwards for one layer. At this time, the two electric attaching supports which are movably arranged on each lifting upright post automatically shrink to enable the electric attaching supports to be separated from the connection with the embedded parts, then the electric attaching supports are driven by the lifting upright posts to rise to the middle part and the top part of the lifting upright post along the vertical direction, namely to the embedded parts corresponding to the previous floor respectively, and then after the two electric attaching supports which are movably arranged are automatically opened, the electric attaching supports which are fixedly arranged on the lifting upright post and positioned at the middle part and the top part respectively correspondingly extend into the embedded parts which are fixedly arranged on the lifting upright post and are locked. And then, three rows of electric attachment supports fixedly arranged on each lifting upright post automatically shrink to enable the electric attachment supports to be separated from the connection with the embedded part, then the electric attachment supports are respectively lifted to the embedded part corresponding to the previous floor along the vertical direction under the drive of the lifting upright posts, and then the three rows of electric attachment supports are automatically opened and then extend into the embedded part corresponding to the previous floor and are locked, so that the whole process of climbing up one layer of protective net is completed. As shown in fig. 3 and 4, fig. 3 and 4 show a state that the attached automatic lifting operation safety protection platform for building construction is attached to a building wall body after climbing for one layer.

After the whole construction of the building is finished, the whole protective net can be lowered layer by layer until the protective net is lowered to the lowest floor, so that the protective net can be conveniently detached. The specific process of the whole descending of the protective net is opposite to the climbing process, so the protective net can be implemented by referring to the climbing process, and the detailed description is omitted.

When the protective net wholly climbs or descends, each lifting upright post needs to keep synchronous action, so that the protective net wholly can automatically, stably and rapidly adhere to lifting operation.

It should be noted that, according to the actual use requirement, a person skilled in the art can set the number of electric attachment supports of other rows of fixed settings and the number of electric attachment supports of adaptive movable settings on the lifting upright, and set the number of corresponding embedded parts at the same time, so that the purpose of climbing or descending the protective net on the building wall can be achieved, and the specific setting mode is not repeated here.

In conclusion, under the combined action of the lifting upright post, the electric attachment support and the embedded part, the whole protective net can be attached to a building wall, meanwhile, the electric attachment support and the embedded part can be quickly connected and disconnected with the building wall, then the lifting of the lifting upright post and the alternate climbing and descending coordination of the three rows of fixedly arranged electric attachment supports and the two movably arranged electric attachment supports on the lifting upright post are utilized, the integral climbing and descending of the protective net are realized, the speed is quick and stable in climbing and descending, the defect that the support frame is required to be continuously removed and then built is overcome, the construction time is saved, the construction cost is saved, the construction difficulty is reduced, the safety is high, and the construction operation is convenient.

Based on the above examples, in a specific embodiment, referring specifically to fig. 5 to 10, the lifting column 100 mainly includes:

a steel base 101 having a C-shaped column structure in cross section and having a notch 1011 provided in a height direction;

the screw rod 102 is arranged in the steel seat 101 and is close to one side of the notch 1011, and a driving motor 103 is arranged at the top of the screw rod 102 to drive the screw rod 102 to rotate;

The first sliding rail 104 is arranged in the steel seat 101 and is far away from one side of the notch 1011, and the first sliding rail 104 is fixedly connected with the steel seat 101;

the first sliding tables 105 are arranged in the steel seat 101 and are fixedly connected to the screw rod 102 at equal intervals along the height direction of the screw rod 102, and the first sliding tables 105 are also connected with the first sliding rail 104 in a buckling manner.

In this embodiment, the lifting column comprises a steel seat of cylindrical structure, the cross section of which is C-shaped, and one side of which has a notch along the height direction. The steel seat can be made of square steel with hollow inside and 5mm wall thickness, and a notch is formed in one side of the steel seat along the height direction.

The steel seat is internally provided with a screw rod, and the top of the screw rod is provided with a driving motor, so that the screw rod can rotate under the driving of the driving motor. Therefore, after two movably arranged electric attaching supports are further arranged on the screw rod at equal intervals along the height direction of the screw rod, the two movably arranged electric attaching supports can extend out of the steel seat from the notch of the steel seat and move up and down along the vertical direction along with the rotation of the screw rod.

Similarly, after three rows of fixed electric attaching supports are further symmetrically arranged on two sides of the outer portion of the steel seat at equal intervals, the distance between the two movable electric attaching supports is the same as that between the three rows of fixed electric attaching supports, so that the movable electric attaching supports can be positioned on the same horizontal plane with the two fixed electric attaching supports on one row when moving along the vertical direction.

When the protective net is required to climb up for one layer, the driving motor rotates forward to enable the screw rod to rotate forward, and the two electric adhesion supports which are movably arranged are driven to move upward along the vertical direction, so that the two electric adhesion supports which are movably arranged are respectively lifted to the middle part and the top part of the lifting upright post from the bottom part and the middle part of the lifting upright post, namely, the electric adhesion supports are respectively lifted to the embedded parts corresponding to the previous floor, and the electric adhesion supports which are movably arranged are automatically opened and then extend into the embedded parts corresponding to the previous floor and are locked. And then, the driving motor reversely rotates to enable the screw rod to reversely rotate and drive the two electric attaching supports which are movably arranged to downwards move along the vertical direction, so that the two electric attaching supports which are movably arranged respectively descend from the top and middle positions of the lifting upright post to the middle and bottom positions of the lifting upright post.

In the process, the two electric attaching supports which are movably arranged are always in a state of being locked by the embedded part, so that when the two electric attaching supports which are movably arranged move downwards along the vertical direction, the steel seat drives the three rows of electric attaching supports which are fixedly arranged on the steel seat to rise reversely. When the floor is lifted, the three rows of electric attachment supports are automatically contracted to separate from the connection with the embedded parts, then are respectively lifted to the embedded parts corresponding to the previous floor along the vertical direction under the drive of the steel seat, and then are automatically opened and then extend into the embedded parts corresponding to the previous floor and are locked, so that the whole process of lifting the protection net upwards for one layer is completed.

The steel seat is internally provided with a sliding rail and a plurality of sliding tables, wherein the sliding rail is equal to the steel seat in length, the upper end and the lower end of the sliding rail are respectively flush with the upper end and the lower end of the steel seat, and the sliding rail is fixed with one side, away from the notch, of the steel seat through bolts. The sliding tables are fixedly connected to the screw rod at equal intervals along the height direction of the screw rod respectively and connected to the sliding rail in a buckling manner, so that each sliding table can move along the sliding rail in the vertical direction when the screw rod rotates.

Because the bottom of lead screw is not connected with the steel seat, therefore when the lead screw is rotatory under driving motor's drive, through set up a plurality of slip tables that can follow the slide rail and move in vertical direction on the lead screw, can realize the location of lead screw in vertical direction, prevent that it from appearing the skew in rotatory in-process, can ensure like this that the electronic attached support of two activity settings that set up on the lead screw can accurately stretch into corresponding built-in fitting and be locked.

In addition, an electrical control cabinet is arranged on the scaffold board laid on the main frame, and the electrical control cabinet is in signal connection with the driving motor to control the driving motor. When the protective net wholly climbs or descends, the electric control cabinet uniformly controls the driving motors on the lifting upright posts, so that the lifting upright posts keep synchronous action, and the protective net wholly can automatically, stably and rapidly carry out attached lifting operation. Preferably, the electrical control cabinet is a PLC control cabinet.

Preferably, referring specifically to fig. 5 to 9, a plurality of connection fasteners 110 are provided on the side of the outer portion of the steel base 101 opposite to the notch 1011 in the height direction thereof to connect the main frame 400.

Specifically, the back of the steel seat is provided with a plurality of connection fasteners along the height direction thereof, and the connection fasteners are used for installing the main frame. The connecting fastener comprises two parts, wherein one part is fixedly arranged on the steel seat, and the other part is connected with the part through a bolt. After the two parts are connected, a hollow structure capable of accommodating the frame body of the main frame is formed in the middle. The arrangement is convenient for connecting and dismantling the main frame.

Based on the above example, in a specific embodiment, referring to fig. 5 to 10 and 11, two fixing assemblies 106 are disposed on the screw rod 102 at equal intervals along the height direction, the fixing assemblies 106 include screw nut 1061 and guide holder 1062, the screw nut 1061 is sleeved on the screw rod 102, the guide holder 1062 is sleeved on the screw nut 1061, one end of the guide holder 1062 sleeved on the screw nut 1061 is fixedly connected with the first sliding table 105, and the other end extends outwards from the notch 1011 to the outside of the steel seat 101 to connect with the movably disposed electric attachment support 200.
