Description

Technical Field

[0001] The invention relates to the technical field of concrete pole skeleton equipment, in particular to a fixing device for manufacturing an annular concrete pole skeleton. Background Art

[0002] In order to improve the supporting strength of concrete poles, it is usually necessary to install a cage-shaped steel frame inside the concrete poles. The cage-shaped steel frame requires a fixing device for making a ring-shaped concrete pole frame during manufacturing. The components for positioning the skeleton steel bars on the existing pole frame fixing devices are mostly separately set, lacking power connection and cannot be driven synchronously, resulting in the need to operate all the fixed components in sequence when tightening the skeleton steel bars, which is troublesome, laborious and inconvenient to use, resulting in low efficiency in disassembly of the skeleton steel bars. In addition, the frames for supporting and holding the skeleton steel bars are mostly fixed-length static installations, which cannot be used to support and manufacture skeleton steel bars of different lengths, and have a relatively single application problem.

The hoist 3 can drive the tensioning machine base 6 to slide forward by pulling the wire rope, and the two The skeleton on the chuck 5 is stretched straight, which is convenient for personnel to tie and hold the iron ring on it. In addition, the brake mechanism on the winch 3 can position the tensioning machine base 6 in the use posture after sliding adjustment; a traction wheel 601 is rotatably installed inside the vertical part of the tensioning machine base 6, and a positioning frame 102 with a U-shaped structure is welded and fixed to the top of the rear side of the frame 1, and a guide wheel 103 is rotatably installed in the internal space of the positioning frame 102; a convex mounting frame 2 is fixed to the ground at an adjacent position on the front side of the frame 1 by means of expansion screws, a second motor is installed on the bottom plate of the convex mounting frame 2, and a chuck 5 is also rotatably installed on the top of the convex mounting frame 2, and a worm gear reducer 4 is installed on the front side of the top of the convex mounting frame 2. The second motor and the worm gear reducer 4 are connected to the front chuck 5 through a belt drive. The self-locking principle of the worm gear mechanism can keep the two chucks 5 in the rotationally adjusted posture in real time to avoid the two chucks 5 from rotating unstably in the forward and reverse directions when tying the iron rings, which hinders the tying operation. The second motor and the worm gear reducer 4 can rotate to drive the skeleton to rotate, which saves the trouble of manually turning the skeleton when tying the iron rings, and is convenient and labor-saving to use. The center positions of the two chucks 5 are welded with two rotating shafts 502 in left and right directions, and two circles of positioning ear blocks 504 are welded around the two sides of the two chucks 5 facing the two rotating shafts 502 at an inner and outer interval, wherein the inner circle positioning ear block 504 is composed of six positioning ear blocks 504, and the outer circle positioning ear block 504 is composed of six positioning ear blocks 504. The positioning ear block 504 is composed of twelve positioning ear blocks 504, and these twelve positioning ear blocks 504 are in groups of two; a positioning piece 7 is slidably installed on the twelve groups of positioning ear blocks 504 of the two chucks 5; six steel bar through-holes are opened in a circular array on the chuck 5, and six steel bars that make up the concrete pole skeleton are surrounded by the twelve steel bar through-holes on the two chucks 5, and the sockets on the positioning sleeve 501 are connected with the steel bar through-holes; a hanging ring is welded in the middle of the top of the positioning frame 102, and a steel wire rope is tightly connected to the hanging ring, and the steel wire rope passes through the traction wheel 601 and the tail end of the guide wheel 103 in turn and is connected to the winch 3; the positioning piece 7 is a rectangular L-shaped bent structure, and the threaded shaft 505 is screwed through with the tail end connecting strut of the positioning piece 7.

[0029] like Figure 2 As shown, six positioning sleeves 501 are welded around the outer circle of the chuck 5, and six threaded shafts 505 are rotatably installed on the inner circle positioning ear block 504. The two chucks 5 can support and insert the six steel bars arranged around. The six steel bars form the skeleton inside the concrete pole, and the skeleton composed of the six steel bars can be rotated by the two chucks 5, which makes it convenient for the staff to tie and retain the iron rings on the bracket, eliminating the trouble of reaching out to arrange the iron rings around the skeleton.

[0030] like Figure 5 As shown, there is a driving ring 503 rotatably mounted on the two rotating shafts 502, and two circles of teeth are set on the two driving rings 503 on the side facing the two chucks 5. The driving ring 503 can engage with a circle of teeth to drive a circle of six threaded shafts 505 to rotate synchronously forward and reverse, providing a driving force for the six positioning parts 7 to be inserted and pressed inward and outward, so that the chuck 5 can perform the pressing and fixing operation of the six steel bars at one time synchronously, eliminating the trouble of fixing the six steel bars in steps, simplifying the positioning and loosening steps of the skeleton steel bars, saving time and efficiency.

Through the pressing shaft 701, the positioning member 7 can be fixed and loosened by the steel bar when sliding in and out, thereby completing the tightening of the steel bar.

[0032] Working principle: during operation, first, six steel bars are sequentially inserted into the twelve steel bar through-holes on the two chucks 5, so that the twelve steel bars are supported between the two chucks 5, and the six steel bars are surrounded to form the skeleton inside the concrete pole, and then the two driving circles 503 are rotated forward in sequence, and the two driving circles 503 can mesh through the two circles of gear pieces thereon to drive the two circles of six threaded shafts 505 to rotate forward synchronously, and the forward rotation of the threaded shaft 505 can drive the positioning member 7 to slide inward, and through the top pressure shaft 701, the positioning member 7 can press the steel bar to be fixed when sliding inward, and then the winch 3 and the wire rope thereon are pulled to drive the tensioning machine base 6 to slide forward, and the skeleton on the two chucks 5 is straightened, and then the iron ring is tied and wound to fix it. When the iron wire is tied and wound, the second motor and the worm gear reducer 4 can drive the two chucks 5 and the steel bar skeleton thereon to rotate, which is convenient for personnel to operate;

[0033] In addition, the brake mechanism on the winch 3 can position the tensioning machine base 6 in the sliding adjustment usage posture.
