The wing plates 12 are installed on both sides of the webs 11. The locking holes 101 are opened on the webs 11 and penetrate the two webs 11. A connecting pipe 13 is provided in the slide rail 10. The connecting pipe 13 connects the locking holes 101 of the two webs 11.

[0058] The connecting tube 13 serves as a guide for the insertion of the pin 28 on one hand, and also as a stiffener to improve the strength of the slide rail 10 on the other hand. Furthermore, the locking hole 101 on the web 11 has a larger hole diameter near the locking hole 101 of the pin 28 than the hole diameter far from the locking hole 101 of the pin 28, which can facilitate the insertion of the pin 28 into the locking hole 101, and the connecting tube 13 is designed to be a matching cone.

[0059] In one embodiment, the linear drive mechanism 27 may be a crank rocker mechanism, a gear rack structure, or an electric push rod, as long as the linear motion of the pin 28 can be achieved.

[0060] Please refer again Figure 2 and Figure 3 In a specific embodiment, the linear drive mechanism 27 includes a motor 271, an output gear 272 and a rack 273. The motor 271 is mounted on the pulley base 24, the output gear 272 is connected to the output shaft of the motor 271, the rack 273 is meshed with the output gear 272, and the rack 273 is connected to the pin 28.

[0062] Please also read Figure 2 and Figure 4In a specific embodiment, the linear drive mechanism 27 includes a motor 271, a crank cam 276 and a connecting rod 277. The motor 271 is mounted on the pulley base 24, the crank cam 276 is connected to the output shaft of the motor 271, and the connecting rod 277 is hinged to the crank cam 276 and the pin 28. The motor 271 can drive the crank cam 276 to rotate, and the crank cam 276 can drive the connecting rod 277 to swing due to the eccentric rotation, and finally realize the telescopic movement of the pin 28.

[0063] In one embodiment, the pin mechanism 26 further includes a first proximity switch 291, a second proximity switch 292, and a third proximity switch 293 mounted on the pulley base 24. The first proximity switch 291 and the second proximity switch 292 are respectively located on opposite sides of the slide rail 10, and the third proximity switch 293 is correspondingly arranged with the linear drive mechanism 27. Specifically, when the linear drive mechanism 27 is a gear rack 273 structure, the third proximity switch 293 is located at the end of the rack 273 away from the pin 28; when the linear drive mechanism 27 is a crank rocker mechanism, the third proximity switch 293 is correspondingly arranged with the crank cam 276.

[0064] Among them, the first proximity switch 291 is used to detect whether the pin shaft 28 is inserted into the locking hole 101, the second proximity switch 292 is used to detect whether the pin shaft 28 is out of the locking hole 101, and the third proximity switch 293 is used to detect the position of the pin shaft 28. The detection of the locked state of the pin shaft 28 is designed with safety redundancy, which is detected by the first proximity switch 291 and the third proximity switch 293, and the open state is detected by the second proximity switch 292 to ensure safety.

[0065] In one embodiment, the pin 28 is a stepped shaft, and the diameter of the pin 28 gradually increases in the direction away from the locking hole 101, so that it can be easily inserted into the locking hole 101 of the slide rail 10. The connection between the rack 273 and the pin 28 is designed as a waist-shaped hole to accommodate the swing of the pin 28 during the insertion process.

[0066] See also Figure 6 and Figure 7 The frame structure 30 is mounted on the step-and-climb mechanism 20, and the frame structure 30 can rise with the climbing of the step-and-climb mechanism 20. In one embodiment, the slide rails 10, the step-and-climb mechanism 20 and the frame structure 30 are each provided with two groups, the two groups of slide rails 10 are arranged in parallel at intervals, the two groups of climbing mechanisms are respectively mounted on the two groups of slide rails 10, and the two groups of frame structures 30 are respectively connected to the two groups of step-and-climb mechanisms 20 to ensure the stability of the load-bearing platform 40 and the working platform 50 on the frame structure 30.

[0067] In one embodiment, the frame structure 30 includes a load-bearing frame 31 and a telescopic driving member 32. The load-bearing frame 31 is installed on the stepping climbing mechanism 20. The load-bearing frame 31 is a quadrilateral structure. The four sides of the load-bearing frame 31 are hinged in sequence. The telescopic driving member 32 is arranged in the load-bearing frame 31. Figures 8 to 10 As shown, the telescopic driving member 32 is used to drive the bearing frame 31 to deform so that the top edge of the bearing frame 31 is horizontal, thereby ensuring that the upper bearing platform 40 and the working platform 50 are approximately horizontal.

[0068] Specifically, the load-bearing frame 31 includes two sets of parallel cross beams 312 and two sets of vertical rods 314, wherein the two ends of the vertical rods 314 are respectively hinged to the ends of the upper and lower cross beams 312, thereby forming a deformable parallelogram structure. One of the vertical rods 314 of the load-bearing frame 31 is connected to the upper pulley 21 of the step-by-step lifting mechanism, so that the load-bearing frame 31 is installed on the step-by-step climbing mechanism 20. Furthermore, a guide pulley 60 is also provided at the bottom end of the vertical rod 314, and the guide pulley 60 is slidably arranged on the slide rail 10, and the guide pulley 60 guides and limits the frame structure 30 to ensure the stability of the up and down movement of the frame structure 30.

[0069] In one embodiment, the stepping climbing mechanism 20 is provided with a first articulated seat 61 and a second articulated seat 62 at intervals, the upper end of the supporting frame 31 is articulated with the first articulated seat 61 through a first connecting shaft 63, and the lower end of the supporting frame 31 is articulated with the second articulated seat 62 through a second connecting shaft 64. Specifically, the first adhesive seat is provided on the upper pulley 21, the second articulated seat 62 is provided on the guide pulley 60, the vertical rod 314 of the supporting frame 31 is provided with the first articulated seat 61 and the second articulated seat 62 correspondingly, the first connecting shaft 63 articulates the two first articulated seats 61, and the second connecting shaft 64 articulates the two second articulated seats 62.

[0070] The first connecting shaft 63 and the second connecting shaft 64 are perpendicular to each other, and there is a gap between the side wall of the supporting frame 31 and the first hinge seat 61, so that the supporting frame 31 can move on the first connecting shaft 63, that is, the supporting frame 31 can move left and right on the first connecting shaft 63. Among them, the two connecting shafts are perpendicular to each other in space. When the tower body 1 has a splicing error during splicing, causing the slide rails 10 on the two sections of the tower body 1 to be slightly non-parallel, the center lines of the upper pulley 21 and the guide pulley 60 at this time have an angle. Since the supporting frame 31 can move on the first connecting shaft 63, the hinge position of the guide pulley 60 can automatically rotate to prevent jamming, so that the frame structure 30 can automatically adapt to track changes when the tracks are not parallel.

[0071] In one embodiment, the telescopic drive member 32 is an electric telescopic rod. It is understandable that in other embodiments, the telescopic drive member 32 may also adopt other structures capable of achieving lifting motion, such as a lifting hydraulic cylinder. Two groups of telescopic drive members 32 are provided, and the two groups of telescopic drive members 32 are respectively provided in the two supporting frames 31 to synchronously drive the two groups of supporting frames 31 to deform synchronously.

[0072] The bearing platform 40 is arranged on the bearing frame 31, and the bearing platform 40 is used to carry the upper working platform 50. The working platform 50 is arranged on the bearing platform 40, mainly providing a construction position for workers, and the working platform 50 is welded by square steel pipes, arranged close to the tower body 1, and fenced around.

[0073] In one embodiment, the two ends of the carrying platform 40 are respectively a fixed end 41 and a movable end 42, the fixed end 41 of the carrying platform 40 is hinged on the top edge of one of the carrying frames 31, the top edge of the other carrying frame 31 is installed with a limit frame 43, and the movable end 42 of the carrying platform 40 is inserted into the limit frame 43. Figures 11 to 13 As shown, when the tower body 1 is in a twisted state, the tracks on the tower body 1 are no longer parallel to each other, one end of the bearing platform 40 is hinged to the bearing frame 31, and the other end of the bearing platform 40 can move in the limit frame 43, releasing multiple degrees of freedom, so that the bearing platform 40 can adapt to the twisting of the tower body 1 to prevent it from getting stuck.

[0074] In one embodiment, the movable end 42 of the carrying platform 40 is provided with a roller 46, and the roller 46 is used to contact the inner wall of the limit frame 43. The movable end 42 of the carrying platform 40 moves in the limit hole through the roller 46, which can facilitate the free movement of the carrying platform 40 and avoid the hard contact between the movable end 42 and the inner wall of the limit frame 43, which may damage the limit frame 43.

[0075] Please refer again Figure 7 In one embodiment, the carrying platform 40 includes two parallel bearing beams 44 and a crossbar 45 connecting the two bearing beams 44. One end of the bearing beam 44 is hinged to the crossbar 312 of the carrying frame 31 through a hinge seat. The limiting frame 43 is designed with two groups, and the two bearing beams 44 are respectively inserted into the two limiting frames 43, which can ensure the stability of the carrying platform 40 during movement.

[0076] In one embodiment, the frame structure 30 further includes an inclination sensor 33, which is installed on the load-bearing frame 31. Specifically, the inclination sensor 33 is installed on the crossbeam 312 at the top edge of the load-bearing frame 31. The inclination sensor 33 is used to detect the inclination state of the frame structure 30. When the frame structure 30 is in an inclined state, the telescopic drive member 32 lifts and retracts the load-bearing frame 31, adjusts the top edge of the load-bearing frame 31 to be in a horizontal state, and finally ensures that the load-bearing platform 40 is level.

[0077] In one embodiment, the frame structure 30 further includes an electric control platform 34, one end of which is hinged to the bottom edge of one of the bearing frames 31, and a limit frame 43 is provided at the bottom edge of the other bearing frame 31, and the other end of the electric control platform 34 is inserted into the limit frame 43. The electric control platform 34 is used to install control components of the bearing stepping lifting platform, and the principle is similar to that of the bearing platform 40. One end of the electric control platform 34 is hinged to the bearing frame 31, and the other end of the electric control platform 34 can move in the limit frame 43, releasing multiple degrees of freedom, so that the electric control platform 34 can adapt to the distortion of the tower body 1 and prevent it from getting stuck.

[0078] In one embodiment, the frame structure 30 further includes a protective guardrail 35 , which connects the two groups of supporting frames 31 . The protective guardrail 35 is disposed on the side of the supporting frame 31 to ensure the safety of personnel working on the electric control platform 34 .

[0079] See also Fig.14 The present invention also provides a method for using the step-by-step climbing platform, which comprises the following steps:

[0080] Step S110 : arranging the slide rail 10 on the tower body 1 .

[0081] Specifically, the connecting seat is welded and fixed on the tower body 1 at a certain interval, and then the slide rail 10 is fixed to the connecting seat by bolts, so as to install the slide rail 10 on the tower body 1. Two groups of slide rails 10 are installed and arranged at intervals, and the two groups of slide rails 10 are arranged in parallel at intervals.

[0082] Step S120 : installing the step-and-climb mechanism 20 on the slide rail 10 , and installing the supporting frame 31 of the frame structure 30 on the step-and-climb mechanism 20 .

[0083] Specifically, the upper pulley 21, the lower pulley 22 and the guide pulley 60 are installed on the slide rail 10, the two ends of the servo electric cylinder 23 are respectively hinged to the upper pulley 21 and the lower pulley 22, and the two sets of stepping climbing mechanisms 20 are respectively installed on the two slide rails 10. The linear drive mechanism 27 on the upper pulley 21 and the lower pulley 22 drives the pin to be inserted into the locking hole 101, so as to achieve the locking of the upper pulley 21 and the lower pulley 22.

[0084] The platform 40 is mounted on the two bearing frames 31, and the working platform 50 is mounted on the bearing platform 40, and the platform assembly is completed. Then, a crane is used to lift the assembled platform to a predetermined position, and the upper end of the bearing frame 31 is hinged to the upper pulley 21, and the lower end of the bearing frame 31 is hinged to the guide pulley 60, so that the assembled platform is installed on the stepping climbing mechanism 20.

[0085] Step S130: The stepping climbing mechanism 20 climbs along the slide rail 10 until it climbs to a predetermined position.

[0086] See also Figures 15 to 20 Specifically, first, the pins 22 of the upper trolley 21 and the lower trolley 22 are in a locked state inserted into the locking hole 101. Then, the linear drive mechanism 27 of the upper trolley 21 drives the pin to be pulled out of the locking hole 101, and the second proximity switch 292 detects that the pin is pulled out in place. After detecting that the pin of the lower trolley 22 is fully inserted and the pin of the upper trolley 21 is fully pulled out, the servo electric cylinder 23 is lifted by 200 mm. The linear drive mechanism 27 of the upper trolley 21 drives the pin to be inserted into the locking hole 101 until both the first proximity switch 291 and the third proximity switch 293 detect that the pin is locked in place.

[0087] After detecting that the latch of the upper trolley 21 is locked in place, the latch of the lower trolley 22 is pulled out until the second proximity switch 292 detects that it is pulled out in place. After detecting that the latch of the upper trolley 21 is completely locked and the latch of the lower trolley 22 is completely pulled out, the servo electric cylinder 23 retracts 200 mm. The latch of the lower trolley 22 is inserted into the locking hole 101 until the proximity switch detects that it is locked in place.

[0088] The above is the climbing beat process of the stepping climbing mechanism 20. Repeat the above work to realize the upward climbing of the entire equipment. If the platform climbs downward, just do it in reverse.

[0089] Step S140: the telescopic driving member 32 drives the carrying frame 31 to deform, so that the carrying platform 40 maintains a horizontal state.

[0090] Specifically, after the inclination angle of the tower body 1 changes, the inclination sensor 33 outputs a signal, and the telescopic drive member 32 can drive the bearing frame 31 to deform, thereby ensuring the levelness of the upper bearing platform 40 and the working platform 50. When the tower body 1 is in a twisted state, the tracks on the tower body 1 are no longer parallel to each other, one end of the bearing platform 40 is hinged to the bearing frame 31, and the other end of the bearing platform 40 can move in the limit frame 43, releasing multiple degrees of freedom, so that the bearing platform 40 can adapt to the twisting of the tower body 1 and prevent it from getting stuck.

[0091] Step S150 : an operator constructs the tower body 1 on the working platform 50 .

[0092] Specifically, the operators perform welding and assembly of the segments of the tower body 1 on the working platform 50 , as well as other construction processes.

[0093] The above-mentioned step-by-step climbing platform and the use method thereof can ensure the normal construction of the tower body 1, and solve the problems of construction difficulties, high safety risks, long construction period and high cost caused by the inclination of the tower body 1 itself.
