DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 are within the scope of protection of the present invention.

[0019] like Figures 1 to 10 As shown, a tower construction machine for building a tower 3 includes several support frames 1 and building platforms embedded in the ground. The support frames 1 are fixed to the surface of the tower 3 through wall attachments 2 during the construction of the tower 3. A climbing device 4 is arranged on each support frame 1. The building platform is in an annular structure. The building platform is installed on each climbing device 4, so that it can be lifted and lowered along the support frame 1 under the drive of the climbing device 4. The building platform includes a working platform 5 and a fixed bracket 6. The fixed bracket 6 is connected to the climbing device 4. A lifting device is arranged on the side end of the fixed bracket 6 to lift building materials through the lifting device. The working platform 5 is installed on the top of the fixed bracket 6. Several extension platform assemblies are arranged around one end of the fixed bracket 6 close to the tower 3. The building platform is driven by the climbing device 4 to move from top to bottom, so that the curtain wall construction of the tower 3 is carried out layer by layer from top to bottom, and the support frame 1 and the wall attachments 2 are removed during the descent, so that the entire mechanism is simultaneously removed from the tower 3 when the construction is completed, completing the entire construction process.

[0020] The extension platform assembly includes an extension platform 7, a telescopic cylinder, a guide frame 8 and an extension mechanism. A plurality of guide frames 8 are fixedly installed on one end of the extension platform 7 close to the fixed bracket 6. A slideway corresponding to the guide frame 8 is provided on the fixed bracket 6. The extension platform 7 is slidably installed on the fixed bracket 6 through the guide frame 8. The telescopic cylinder is connected between the extension platform 7 and the fixed bracket 6 to drive the extension platform 7 to move horizontally according to the different outer diameters of the tower 3. The extension mechanism is movably arranged on the extension platform 7. The extension mechanism is connected between two adjacent extension platforms 7 by moving to the side of the extension platform 7 and abutting against another adjacent extension platform 7.

[0021] In this embodiment, the extension mechanism includes a plurality of extension components, which are evenly spaced along the length direction of the extension platform 7 and are assembled at the left end of the extension platform 7. The extension component includes a sealing cavity 9 and an extension plate 10. The sealing cavity 9 is opened inside the extension platform 7, and the left end of the sealing cavity 9 is connected with the left end surface of the extension platform 7. The extension plate 10 is slidably assembled in the sealing cavity 9. A sealing member 11 is provided at the right end of the extension plate 10, and the sealing member 11 abuts against the inner wall of the sealing cavity 9. A plurality of sliding rods 12 are provided at the bottom of the extension plate 10, and the sliding rods 12 are slidably connected with the extension platform 7. , each slide rod 12 is sleeved with a first spring 13, and the first spring 13 is connected between the left end of the seal 11 and the inner wall of the sealing cavity 9; the right end face of the extension platform 7 is provided with a plurality of bayonet holes 14 corresponding to each extension plate 10; a high-pressure hose is connected to the fixed bracket 6, and a delivery pipe 15 is provided at the right end of each sealing cavity 9, and the other end of the delivery pipe 15 is connected to a control valve 16, and the other end of each control valve 16 is connected to the high-pressure hose through a pipeline, and the high-pressure hose is connected to a power pump, so that a high-pressure fluid is introduced into the high-pressure hose through the power pump.

[0022] When the curtain wall of the tower 3 is being constructed, the fixed bracket 6 is driven to move up and down by the lifting device. When it moves to the surface to be constructed, the distance between the fixed bracket 6 and the surface of the tower 3 at that location is monitored by the sensor module, thereby generating a signal to each telescopic cylinder, and the extension platform 7 is driven by the telescopic cylinder to move toward the tower 3, and then approach the surface of the tower 3. Since each extension platform 7 is distributed in a surrounding manner, when the extension platform 7 is extended to different positions, the interval between two adjacent extension platforms 7 is different (the longer the extension platform 7 is extended, the smaller the interval between the two extension platforms 7 is). At this time, the control system determines the extension plate 10 that needs to be extended according to the extension degree of the extension platform 7, thereby controlling the corresponding control valve 16 to open, and then the power pump introduces high-pressure fluid into the high-pressure hose. The high-pressure fluid enters the sealing chamber 9 through the opened control valve 16, thereby pushing the sealing member 11 to move outward, so that the extension plate 10 moves outward until it is inserted into the slot 14 of the side extension platform 7, so that the extension plate 10 connects two adjacent extension platforms 7, and finally the extension platform 7 and the extension plate 10 form an annular platform for workers to perform construction operations.

[0023] In this embodiment, a accommodating cavity 17 is provided at the left end of the extension plate 10, and an adjusting plate 18 is slidably connected inside the accommodating cavity 17. A second spring 19 is connected between the right end of the adjusting plate 18 and the inner wall of the accommodating cavity 17. A top block 20 adapted to the accommodating cavity 17 is provided on the bayonet 14. When the extension plate 10 is inserted into the bayonet 14, the top block 20 abuts against the adjusting plate 18 and causes the adjusting plate 18 to move to the right. A plurality of through openings 21 connected to the accommodating cavity 17 are provided on the top of the extension plate 10, and a support block 22 is slidably provided in each of the through openings 21. A third spring 23 is provided at both ends of the bottom of the support block 22, and the other end of the third spring 23 is connected to the bottom end of the accommodating cavity 17. When the support block 22 rises to the highest point through the third spring 23, the support block 2 The top surface of the adjusting plate 18 is in the same horizontal plane as the top surface of the extension platform 7; the top surface of the adjusting plate 18 is provided with a plurality of supporting components corresponding to each supporting block 22, and the supporting components include a fixing seat 24, a support 25 and a fourth spring 26, the fixing seat 24 is fixedly assembled on the top surface of the adjusting plate 18, the support 25 is slidably installed on the top surface of the adjusting plate 18, and the fourth spring 26 is connected between the fixing seat 24 and the support 25. When the adjusting plate 18 moves to the right, the support 25 moves synchronously to the bottom of the raised supporting block 22, the top of the right end of the supporting block 22 is an inclined structure, and the top of the right end of the sealing cavity 9 is provided with a matching inclined mouth. The design of the inclined surface and the inclined mouth makes it possible for the supporting block 22 to be automatically collected into the through opening 21 due to the squeezing effect of the inclined mouth when the extension plate 10 is retracted into the sealing cavity 9; When the extension plate 10 moves outward and snaps into the snap-in slot 14 of the adjacent extension platform 7, since there is a top block 20 in the snap-in slot 14, during the snap-in process of the extension plate 10, the top block 20 will first contact the adjustment plate 18. As the extension plate 10 continues to move, the top block 20 will push the adjustment plate 18 to move rightward synchronously, thereby causing the support 25 on the adjustment plate 18 to move rightward as well.

[0024] Because the third spring 23 is provided, when the extension plate 10 moves out of the sealing cavity 9, the support block 22 will rise under the elastic force of the third spring 23. The support 25 is initially located on the left side of the support block 22, and when the support 25 moves rightward, it will reach below the support block 22, thereby supporting the support block 22. At this time, even if an external force is applied to the support block 22, the support block 22 will not move downward.

[0025] Meanwhile, if the extension plate 10 is not completely moved out of the sealing cavity 9, part of the support block 22 is still retracted in the through opening 21. At this time, when the adjustment plate 18 moves to the right, the corresponding support 25 will remain motionless due to the obstruction of the support block 22, and compress the fourth spring 26, so that the support block 22 retracted in the through opening 21 can be prevented from affecting the movement of the adjustment plate 18.

[0026] Since the extension plate 10 is stored in the extension platform 7, in order to ensure the strength of the extension platform 7, there is inevitably a height difference between the top surface of the extension plate 10 and the top surface of the extension platform 7. If the workers do not pay attention to their feet during construction and walk between the extension platform 7 and the extension plate 10, they are easily tripped by the height difference, resulting in body imbalance, and even the risk of falling in serious cases. The design of the support block 22 solves this problem. When the workers walk onto the extension plate 10, the soles of their feet touch the support block 22, eliminating the hidden dangers caused by the height difference.

[0027] In this embodiment, a guardrail is provided on the outer edge of the top surface of the working platform 5, a guardrail 27 is provided on the side of the top surface of the extension platform 7 away from the working platform 5, and a guard seat 28 is provided on the left and right sides of the guardrail 27. A first rotating rod 29 and a second rotating rod 30 are provided on each guard seat 28. A guard rope 31 is connected between the guard seats 28 on all the extension platforms 7, and the guard rope 31 passes around the first rotating rod 29 and the second rotating rod 30 of each guard seat 28 in turn. A motor 32 is installed on one of the extension platforms 7, and a reel 33 is installed on the output shaft of the motor 32. One end of the guard rope 31 is fixed on the guardrail 27 of the extension platform 7, and the other end of the guard rope 31 is connected to the reel 33 after passing through all the guard seats 28. The motor 32 controls the winding and unwinding of the guard rope 31 by driving the reel 33 to rotate; The guardrail 27 on the extension platform 7 can play a protective role and prevent the staff from accidentally falling. Since the extension platform 7 adopts a retractable structure design, the spacing distance between adjacent extension platforms 7 will dynamically change with the retractable state, resulting in the inability to adopt a fixed protective structure. The present application adopts a protective rope 31 to protect the extension plate 10 area; before the extension platform 7 is retracted, the motor 32 first drives the reel 33 to unwind, so that the protective rope 31 is in a relaxed state, thereby avoiding affecting the retraction of the extension platform 7. After the extension platform 7 is retracted, the motor 32 drives the reel 33 to reel, thereby tightening the protective rope 31, so that the protective rope 31 is in a straight state, thereby playing a protective role through the protective rope 31 to prevent the staff from falling from the extension plate 10 area.

[0028] This embodiment also provides a control system for controlling the tower erection machine, including: A control module, used for receiving and processing real-time data from the sensor module and generating driving instructions; The sensor module is used to monitor the distance between the fixed support 6 and the surface of the tower construction machine. By real-time monitoring the distance between the two, it is possible to determine the distance that the extension platform 7 needs to be extended and retracted, thereby ensuring that the extension platform 7 can be moved to a suitable position; The driving actuator, including the telescopic cylinder, the control valve 16 and the power pump, adjusts the movement of the extension platform 7 and the extension plate 10 according to the driving instructions; The safety monitoring module is integrated into the control module and is used to analyze the data from the sensor module in real time and trigger collision warning and emergency braking functions.

[0029] Several monitoring modules are distributed on the working platform 5. The monitoring modules are used to monitor the status of personnel staying on the extension platform 7. The safety monitoring module analyzes the data of the monitoring modules in real time and triggers an alarm. The monitoring modules monitor in real time whether there are personnel or building materials on the extension platform 7. When it is necessary to adjust the extension and retraction of the extension platform 7, if it is detected that there are still personnel staying or building materials placed on the extension platform 7, the emergency brake is triggered and an alarm is sounded to remind the personnel to withdraw to the working platform 5, or to remind the staff to move the building materials on the extension platform 7 to the working platform 5, so as to ensure that there are no objects on the extension platform 7 when it is retracting, so as to avoid safety accidents.

[0030] Load sensor: Each extension platform 7 is equipped with a load sensor. The safety monitoring module analyzes the data of the load sensor in real time and triggers an overload warning. When too many building materials are placed on an extension platform 7, the load sensor detects that the weight on it reaches a preset threshold, and triggers an alarm through the safety monitoring module to remind the staff to distribute the building materials to other extension platforms 7 or work platforms 5, thereby ensuring that the extension platform 7 will not be damaged due to excessive load and there will be no safety risk.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
