Embodiment 2

[0039] The difference between this embodiment and the foregoing embodiment is:

[0040] In some embodiments of the present invention, the support frame 1 includes a support body 11 and a pole 12 disposed on the support body 11, the guide rail 21 is disposed on the top of the support body 11, and the roller set 41 is movably arranged on the pole 12 . Thus, the structure of the supporting frame 1 is simpler and more reliable.

[0041]In some embodiments of the present invention, the roller set 41 includes an adjusting frame 411 and two supporting rollers 412 arranged at intervals, and the two supporting rollers 412 are rotatably arranged on the adjusting frame 411 , and the adjusting frame 411 It is movably arranged on the pole 12 . It can be understood that, by making the adjustment frame 411 move up and down on the pole 12, the position of the support roller 412 can be moved up and down, so as to facilitate the adjustment of the bending angle of the steel strand, so as to be...

Embodiment 3

[0046] The difference between this embodiment and the foregoing embodiment is:

[0047] In some embodiments of the present invention, the positioning member 42 includes two positioning pins 421, the two positioning pins 421 are respectively supported on opposite sides of the pole 12, each of the positioning pins 421 passes through The positioning holes 4112 are arranged at corresponding positions. Thus, the strength of the positioning member 42 is improved, and the stability between the support rod 12 and the adjustment rod 4111 is ensured.

[0048] In some embodiments of the present invention, the two pairs of sides of the pole 12 are provided with support parts 121, each of the support parts 121 is provided with a support hole, and each of the positioning pins 421 passes through in the support hole. It can be understood that the matching strength between the positioning pin 421 and the pole 12 is improved by making the positioning pin 421 pass through the supporting hole. ...

Abstract

The invention relates to the technical field of steel strand manufacturing, and provides a take-up device for prestressed steel strand production. The take-up device for prestressed steel strand production comprises a supporting frame, a wire arranging assembly, a take-up assembly and a pre-bending assembly, wherein the wire arranging assembly comprises a guide rail and a wire arranging sliding block; the wire arranging sliding block is arranged on the guide rail in a sliding mode; the guide rail is arranged at the top of the supporting frame; the upper end of the sliding block is rotationally connected with a supporting rolling wheel; the take-up assembly comprises a take-up reel which is rotationally arranged; the take-up reel is located below supporting rollers in the vertical direction; the pre-bending assembly is arranged on the supporting frame, and comprises the roller set which is rotationally arranged; the roller set is located between the take-up reel and the supporting rolling wheel; and the roller set can move in the vertical direction so as to adjust the bending angle of a steel strand. According to the take-up device for prestressed steel strand production provided by the invention, the steel strand is roughly in an arc shape when being guided by the supporting rolling wheel and the roller sets, and then pre-bending of the steel strand is achieved, so that the stress for bending the steel strand can be reduced, and the steel strand can be stored in order.

Description

technical field [0001] The invention relates to the technical field of steel strand production, in particular to a wire take-up device for producing prestressed steel strand. Background technique [0002] The main characteristics of prestressed steel strands are high strength and good relaxation performance. In addition, they are relatively straight when unfolded. When producing prestressed steel strands, the prestressed steel strands are wound on the take-up reel through the take-up device, such as The patent document with the application number CN201410767133.1 discloses a wire take-up device for a prestressed steel strand bundle. The wire take-up device includes: a polygonal base, on which a plurality of base columns are spaced and vertically fixed, on which a plurality of bases A polygonal take-up support frame is fixed on the top of the column, and a rotating turntable is hinged in the center of the take-up support frame; multiple winding frames and a pair of fixed bloc...
