Description

Technical Field

[0001] The utility model relates to the technical field of equipment for converging multiple steel strands into a bundle, and specifically relates to a steel strand bundling device. Background Art

[0002] During the construction of bridges and railway foundations, when installing precast concrete box girders, multiple steel strands need to be threaded into the prepared corrugated pipe holes. The traditional construction method is to thread single steel strands into the corrugated pipe holes in sequence. However, after multiple threading operations, the steel strands are prone to becoming twisted, which affects the tensioning effect. In severe cases of twisting, safety accidents may occur. Therefore, it has been changed to first comb multiple steel strands into a bundle and then thread the whole bundle of multiple steel strands into the corrugated pipe holes together. Currently, the method of combing into a bundle is to manually arrange multiple steel strands neatly and then tie and fix them, which requires a large amount of labor, has low work efficiency, and it is difficult to unify the tying standards.

[0003] The patent document with the application number 202410788911.9 discloses an anchor hole threading and tensioning system with self-positioning anchor holes, including a moving frame that performs spatial movement. A jack for providing tensile force to the steel strands is horizontally fixed on the moving frame. A cutting machine frame that slides along the output direction of the jack is assembled on the moving frame. Two conveying mechanisms for jointly conveying the steel strands are vertically symmetrically installed on the cutting machine frame. A clamping mechanism for synchronously clamping multiple steel strands is fixedly assembled on the cutting machine frame. The system provided by the present invention avoids the trouble of repeatedly disassembling and assembling the anchor and clamping pieces during the process of tensioning the steel strands in the existing construction, is convenient to operate, is more time-saving and labor-saving, and has higher overall efficiency.

[0004] The clamping mechanism in the above comparative document includes a chuck, a dispersion hole, and a horn-shaped guide block, and can only converge multiple steel strands distributed in a circumferential array in the dispersion hole into a polygon steel strand bundle without a central steel strand after passing through the horn-shaped guide block, and it is not applicable to the scenario of converging multiple common single-layer side-by-side steel strands into a bundle.

[0030] As Figure 1 、 Figure 2 and Figure 3 shown, the present utility model discloses a steel strand bunching device, which includes a frame 1, a wire gathering conical tube 2 and a wire gathering conical pipe 3. The wire gathering conical tube 2 is arranged on the frame 1. The wire gathering conical tube 2 is provided with a first inlet and a first outlet. The wire gathering conical pipe 3 is arranged in front of the wire gathering conical tube 2. The wire gathering conical pipe 3 is provided with a second inlet, a second outlet and a conical tube body connecting the second inlet and the second outlet. The first inlet corresponds to the second outlet. The size of the second outlet is larger than the size of the first outlet and smaller than the size of the first inlet. Among them, multiple single-layer and side-by-side steel strands are gathered and output as multiple multi-layer distributed steel strands through the conical tube body, and the multiple multi-layer distributed steel strands are gathered and output as a steel strand bunch through the wire gathering conical tube 2. It can be understood that after multiple single-layer and side-by-side steel strands are fed into the wire gathering conical pipe 3 from the second inlet, they are guided by the conical tube body into multiple multi-layer distributed steel strands and output from the second outlet. The wire gathering conical tube 2 can further gather and output the multiple multi-layer distributed steel strands fed into it as a steel strand bunch, and can be applicable to the scenario of gathering multiple single-layer and side-by-side steel strands into a bunch.

[0031] In this embodiment, the wire collecting conical tube 2 and the wire collecting tapered tube 3 are arranged on the frame 1 with a common central axis. The second inlet is an elliptical inlet 32, and the second outlet is a circular outlet 31. The circular outlet 31 and the elliptical inlet 32 are arranged with a common central axis. Moreover, the major axis of the elliptical inlet 32 is greater than the diameter of the circular outlet 31, and the minor axis of the elliptical inlet 32 is less than the diameter of the circular outlet 31. Specifically, the conical tube body extends from the elliptical inlet 32 towards the circular outlet 31. Among them, the major axis of the elliptical inlet 32 gradually shortens to the diameter of the circular outlet 31, and the minor axis of the elliptical inlet 32 gradually elongates to the diameter of the circular outlet 31. The inner wall of the conical tube body is smooth, and it can efficiently guide multiple steel strands in a single-layer side-by-side state into a multi-layer distribution state.

[0032] Furthermore, the wire collecting conical tube 2 has a conical tube structure. The diameter of the first inlet is greater than the diameter of the circular outlet 31, and the diameter of the first outlet is less than the diameter of the circular outlet 31. The wire collecting conical tube 2 can further converge multiple steel strands in a multi-layer distribution state output by the wire collecting tapered tube 3 into a bundle. Preferably, the minor axis of the elliptical inlet 32 is greater than the diameter of a single steel strand, and the diameter of the first outlet is slightly greater than three times the diameter of a single steel strand, so that the middle steel strand among multiple single-layer side-by-side steel strands can become the center of the convergence of the steel strand bundle.

[0033] The wire collecting conical tube 2 in this embodiment is movably arranged horizontally on the frame 1 for adjusting the distance between the wire collecting conical tube 2 and the wire collecting tapered tube 3. Specifically, the frame 1 includes a fixed bracket 11, a moving bracket 12, a support rod 13, a connecting piece 14, and a slide rail platform 15. The fixed bracket 11 and the moving bracket 12 are connected by multiple support rods 13. The moving bracket 12 is movably arranged horizontally on the support rod 13. The wire collecting conical tube 2 is installed on the moving bracket 12, and the wire collecting tapered tube 3 is installed on the fixed bracket 11. The upper end of the connecting piece 14 is fixedly connected to the moving bracket 12, and the lower end is adapted to the slide rail at the top of the slide rail platform 15. The moving bracket 12 can drive the connecting piece 14 to slide horizontally on the support rod 13. The slide rail platform 15 supports the moving bracket 12 through the connecting piece 14. By horizontally moving the moving bracket 12, the horizontal distance between the wire collecting conical tube 2 and the wire collecting tapered tube 3 can be adjusted.

[0034] Preferably, in this embodiment, there are four support rods 13. One ends of the four support rods 13 are respectively fixedly installed at the four corners of the fixed bracket 11. The four corners of the moving bracket 12 are sleeved on the support rods 13, which can increase the stability of the horizontal movement of the moving bracket 12. The wire collecting conical tube 2 is installed in the middle of the moving bracket 12, and the wire collecting conical tube 2 and the moving bracket 12 are arranged with a common central axis. The wire collecting tapered tube 3 is installed in the middle of the fixed bracket 11, and the wire collecting tapered tube 3 and the fixed bracket 11 are arranged with a common central axis, which can increase the firmness of the coaxial installation of the wire collecting conical tube 2 and the wire collecting tapered tube 3, and it is not easy to occur central misalignment when multiple steel strands are passed through side by side.

[0035] Further, in this embodiment, a triangular roller set 4 is further included. The triangular roller set 4 is arranged at the first outlet and is used to guide the steel strand bundle to pass through the center of the triangular roller set 4. The triangular roller set 4 is provided with three pulleys 41, and the three pulleys 41 are arranged at the first outlet in a distribution manner of the vertices of an equilateral triangle. The minimum distance between the pulley 41 and the center of the triangular roller set 4 is slightly smaller than the radius of the first outlet, which can avoid excessive scratching between the steel strand bundle and the first outlet, thereby causing wear of the steel strand bundle or the first outlet.

[0036] In this embodiment, an end fixing assembly 5 is further included. The end fixing assembly 5 is arranged outside the first outlet and is used to fix the end of the steel strand bundle. Specifically, the end fixing assembly 5 includes a support platform 51, a clamping jaw 52 and a guiding head 53. The support platform 51 is arranged outside the first outlet, the clamping jaw 52 is installed above the support platform 51, the clamping jaw 52 is used to clamp and fix the guiding head 53, and the guiding head 53 is used to fix the end of the steel strand bundle.

[0037] Continue to refer to Figure 4 , the guiding head 53 includes a circular sleeve 531, a wedge-shaped clamping piece 532 and a conical socket 533. The wedge-shaped clamping piece 532 is arranged in the outlet of the circular sleeve 531 in a radially movable manner. The conical socket 533 is threadedly connected to the outlet of the circular sleeve 531. The wedge-shaped clamping piece 532 is elastically abutted against the conical socket 533, and the conical socket 533 squeezes the wedge-shaped clamping piece 532 to make a clamping action towards the inner side of the circular sleeve 531. The guiding head 53 is arranged coaxial with the wire collecting cone tube 2. The end of the middle steel strand among the multiple single-layer and side-by-side arranged steel strands protrudes from other steel strands. When the steel strand bundle penetrates into the guiding head 53, the end of the middle steel strand squeezes the wedge-shaped clamping piece 532, causing the wedge-shaped clamping piece 532 to move radially outwards to make a loosening action, and further compressing the elastic mechanism in the conical socket 533. After the end of the middle steel strand passes through the wedge-shaped clamping piece 532, it enters the conical socket 533. The ends of other steel strands penetrate into the circular sleeve 531. The elastic mechanism in the conical socket 533 squeezes the wedge-shaped clamping piece 532 to clamp and fix the end of the middle steel strand bundle. The clamping jaw 52 releases the guiding head 53 that has fixed the end of the steel strand bundle, and the steel strand bundle and the guiding head 53 can continue to be conveyed forward so as to obtain a steel strand bundle with a required length.

The inner wall of the conical pipe body is smooth, and can efficiently guide multiple parallel steel strands in a single layer state into a multi-layer distributed state.

[0043] (3) Stable supporting function

[0044] By setting one ends of four support rods to be respectively fixedly installed at the four corners of the fixed bracket, and the four corners of the moving bracket are sleeved on the support rods, the stability of the horizontal movement of the moving bracket can be increased. The wire gathering tapered pipe is installed in the middle of the moving bracket, and the wire gathering tapered pipe and the moving bracket are arranged with a common central axis. The wire gathering conical pipe is installed in the middle of the fixed bracket, and the wire gathering conical pipe and the fixed bracket are arranged with a common central axis, which can increase the firmness of the coaxial installation of the wire gathering tapered pipe and the wire gathering conical pipe, and it is not easy to have a central dislocation when multiple steel strands are passed through side by side.
