Description

Technical Field

[0001] The invention relates to the technical field of wind power station foundation pile construction, in particular to a steel bar binding device for wind power station foundation pile construction. Background Art

[0002] The foundation piles are usually cast-in-place concrete piles, and their main function is to transfer the load they carry to the deep foundation, so as to ensure the stability and safety of the overall structure. The foundation piles in a wind power station generally support the tower and blades of the wind turbine. In the prior art, a steel cage is generally provided in the foundation piles to enhance the strength and bending resistance of the pile body. The steel cage is usually composed of annular reinforcement bars, main bars and stirrups, and the stirrups are usually tied and fixed with steel wires at the positions where they cross and intersect with the main bars.

[0003] The main methods of traditionally tying stirrups are generally manual tying or manual tying using a tying machine. However, the above two main methods of tying stirrups have the following problems: 1. When manually tying stirrups, due to the large number of stirrups that need to be tied on a single steel cage and the large number of positions where each stirrup needs to be tied, it is generally necessary to consume more manpower to tie the stirrups on a single steel cage at the same time. The above tying method not only has high labor costs and a heavy overall manual operation burden, but also the consistency and stability of the manual tying effect need to be further improved; 2. When manually tying stirrups using a tying machine, although the consistency and stability of the tying effect are improved, it still requires more manpower to tie each tying position in turn. The above tying method not only needs to further improve the overall tying efficiency, but also the labor cost and the burden of manual operation need to be further controlled.

[0039] See also Figure 4 , Figure 5 and Figure 7 The linkage assembly 45 includes a speed change wheel 1 451 fixedly arranged on the side of the wire drum 434 away from the motor 2 436 through a rod member 1, wherein the rod member 1 is rotatably connected to the support 4, a support 5 is arranged on the side of the rotating wheel 2 445 away from the spring rod 2 442, and a cam 452 that is rotatably arranged on the support 5 and is squeezed and matched with the rotating wheel 2 445, wherein the support 5 is fixedly arranged on the vertical section of the L-shaped connecting plate 2 441 close to the wire drum 434, and rotating shafts rotatably connected to the support 5 are symmetrically fixedly arranged on both sides of the cam 452, and a connecting rod 2 453 is fixedly arranged on the side of the cam 452 close to the speed change wheel 1 451 through the corresponding rotating shaft, and a speed change wheel 2 454 that is belt-driven with the speed change wheel 1 451 is fixedly arranged on the end of the connecting rod 2 453 away from the cam 452, and the diameter of the speed change wheel 2 454 is larger than the diameter of the speed change wheel 1 451.

[0040] When the steel wire 435 is to be unwound at a fixed length, the movable end of the steel wire 435 is first guided into the guide tube 432, and then the motor 2 436 drives the wire drum 434 to rotate in a directional manner, and the wire drum 434 then continuously unwinds the steel wire 435. At the same time, the speed change wheel 1 451 that rotates synchronously with the wire drum 434 drives the speed change wheel 2 454 and the cam 452 to rotate through the belt transmission. Since the diameter of the speed change wheel 2 454 is larger than the diameter of the speed change wheel 1 451, when the wire drum 434 rotates a specific number of circles, the speed change wheel 2 454 drives the cam 452 to rotate one circle, and the cam 452 then presses the rotating wheel 2 445 to make the spring rod 2 442 drive the blade 443 to insert into the cutting groove 433, thereby cutting off the steel wire 435 of a specific length located on the lower side of the guide tube 432.

[0041] See also Figure 6 and Figure 8 The torsion assembly 46 includes a motor 3 461 fixedly arranged on the telescopic plate 431 near one side of the U-shaped support 3, a U-shaped connecting plate 3 462 is fixedly arranged on the driving end of the motor 3 461, and a torsion seat 463 is fixedly arranged on the two vertical sections of the U-shaped connecting plate 3 462 at one end away from the motor 3 461, wherein the torsion seat 463 is located at the end of the guide tube 432 away from the telescopic plate 431, and two groups of through torsion grooves are centrally symmetrically opened on the torsion seat 463, and each group of torsion grooves is composed of an introduction groove 464 and a gathering arc groove 466 connected by an elastic card groove 1 465, the diameter of the introduction groove 464 is the same as the width of the gathering arc groove 466, and the width of the elastic card groove 1 465 is slightly smaller than the width of the gathering arc groove 466, and the two centrally symmetrical introduction grooves 464 are respectively located at the two ends of the torsion seat 463, wherein the introduction groove 464 close to the guide tube 432 is aligned with the through groove in the guide tube 432.

[0042] See also Figure 6 and Figure 8 The guide assembly 47 includes a guide frame 1 471 located on the side of the torsion seat 463 away from the U-shaped connecting plate 3 462, and the horizontal sections of the two symmetrical L-shaped connecting plates 441 are fixedly provided with the guide frame 1 471, and the ends of the two symmetrical guide frames 471 away from the torsion seat 463 are rotatably provided with guide frames 2 472, and a two-way spring hinge 473 is installed between the guide frame 1 471 and the corresponding guide frame 2 472. The two-way spring hinge 473 adopts the existing technology, and its specific structure is not repeated here. The two symmetrical guide frames 1 471 and the guide frame 2 472 are jointly provided with a U-shaped pipe groove 474 and an elastic card groove 2 475, and the elastic card groove 2 475 connects the U-shaped pipe groove 474 with the inner surfaces of the guide frame 1 471 and the guide frame 2 472, and the width of the elastic card groove 2 475 is slightly smaller than the diameter of the U-shaped pipe groove 474.

[0043] When the position on a single stirrup 13 that needs to be tied is to be tied and fixed, the electric drive mobile vehicle 21 is first used to drive the tying mechanism 4 to move along the steel cage 1 until the position on a certain stirrup 13 that needs to be tied is within the action range of the tying mechanism 4, and then the steel cage 1 is limitedly supported by the rotating wheel 1 347. At this time, taking the uppermost electric push rod 42 as an example, the electric push rod 42 drives the corresponding paired guide frame 2 472 to move to the corresponding tying position on the stirrup 13, and the lower end of the guide frame 2 472 then contacts the stirrup 13. Under the continuous drive of the electric push rod 42, the guide frame 2 472 is then supported. The stirrup 13 is squeezed and rotated inwardly until the binding node where the stirrup 13 and the corresponding main reinforcement 12 cross over the guide frame 2 472 and move to the inner side of the paired guide frame 1 471 and the guide frame 2 472. At this time, the guide frame 2 472 is driven by the bidirectional spring hinge 473 to rotate in the opposite direction and reset, and then the steel wire 435 is continuously unwound into the guide tube 432 through the wire drum 434. The movable end of the steel wire 435 then enters the corresponding introduction groove 464 from the lower end of the guide tube 432, and then is continuously introduced into the U-shaped tube groove 474 under the guidance of the corresponding introduction groove 464 until the steel wire 435 The movable end of the U-shaped fixed-length steel wire 435 enters another introduction groove 464. At this time, the blade 443 just cuts off the U-shaped fixed-length steel wire 435 in the introduction groove 464 and the U-shaped tube groove 474. Then, the torsion seat 463 is driven by the motor 3 461 to continuously rotate in a directional manner, so that the two vertical ends of the U-shaped fixed-length steel wire 435 are first inserted into the gathering arc groove 466 by the corresponding elastic card groove 1 465. With the continuous action of the torsion seat 463, the vertical section of the U-shaped fixed-length steel wire 435 is continuously twisted and wound. At the same time, the U-shaped fixed-length steel wire 435 quickly passes through the elastic card groove 2 475 and is separated from the U-shaped tube groove 474 and stably tied to the opposite The corresponding cross node is formed, thereby binding and fixing the stirrup 13 and the corresponding main reinforcement 12 together, and finally the paired guide frame 472 is driven by the electric push rod 42 to move in the opposite direction, so that the binding node is separated from the inner side of the paired guide frame 1 471 and the guide frame 2 472, thereby completing the binding of the position. The above binding method can automatically bind all the positions that need to be bound on a single stirrup 13 at the same time, thereby reducing the time required for binding a single stirrup 13, improving the binding efficiency of a single stirrup 13, and also ensuring the consistency and stability of the binding effect at each binding position of the stirrup 13.

[0044] The electric-driven mobile vehicle 21 drives the supporting mechanism 3 and the binding mechanism 4 to move a fixed distance from front to back along the steel cage 1, so that the stirrups 13 evenly distributed on the steel cage 1 can be quickly and stably bound in turn. At the same time, during the moving operation of the electric-driven mobile vehicle 21, the part of the steel cage 1 that has been bound is also required to be supported by a supporting frame to prevent the steel cage 1 from bending and deforming under the influence of its own gravity. The above-mentioned binding method greatly improves the overall binding efficiency of the stirrups 13, and also greatly reduces the labor cost required for the overall binding of the stirrups 13 and reduces the overall manual operation burden.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
