Embodiment 1

[0030] see Figure 1-2 , an overall beam threading device for bridge steel strands, including a rectangular sealed box 1, and also includes a beam threading conveying mechanism 2, the beam threading conveying mechanism 2 is installed inside the rectangular sealed box 1 for multiple cables simultaneously For beam transmission, the steel strand locks the beam threading head 3, and the beam threading conveying mechanism 2 is installed inside the rectangular sealed box 1 in parallel with the beam threading conveying mechanism 2 for docking, and multiple cables are connected for synchronous beam transmission. Holding and locking mechanism 4, the clamping and locking mechanism 4 is arranged on the outer side of the steel strand locking and threading head 3, and automatically performs the fixed connection between the steel strand locking and threading head 3 and multiple cables.

[0031] The present invention designs a device for synchronously threading a plurality of bridge steel st...

Embodiment 2

[0033] see Figure 2-3 , based on Embodiment 1, the difference is that the beam threading mechanism 2 includes a wire holder 201 and a wire holder 202; a plurality of the wire holders 201 are distributed along the same horizontal line and reserve gaps for each other, and the wire holders The upper and lower ends of 201 are connected to the inner wall of the rectangular sealed box 1 through brackets. The wire holder 201 is a cylindrical structure arranged horizontally and has a plurality of threading holes 203 uniformly. The wire holder 202 is installed between the two wire holders 201 The position between them is connected and fixed respectively.

[0034]The outside between the wire supports 202 is arranged in an inverted triangle structure, and three rotating shafts 204 are arranged. The middle parts of the rotating shafts 204 are sleeved with grinding rollers 205 that increase friction. The seat 201 is vertical, and the first universal joints 206 are sleeved on both ends of...

Embodiment 3

[0038] see Figure 5-9 , based on Embodiment 1-2, the difference is that the steel strand locking threading head 3 includes a fixed pipe 301 and a threading head 302, and the end of the threading head 302 is fixedly connected with an external threaded pipe 303, the externally threaded pipe 303 is inserted into the interior of the fixed pipe 301 and screwed to it, the inner wall of the fixed pipe 301 near the inner wall of the threaded pipe is fixed with a plurality of limit blocks 304 at equal intervals in a ring, the end of the fixed pipe 301 A fixed plate 305 in a T-shaped column structure is rotatably connected.

[0039] The other end of the fixed pipe 301 is provided with a first limiting hole 306 which is smaller than the hole diameter of the threading hole 203, and the inside of the fixed pipe 301 is provided with a turntable 307 close to the end of the first stop hole 306, and the turntable 307 is provided with a The same as the first limiting hole 306 and correspondin...

Abstract

The invention discloses a bridge steel strand integral strand penetrating device and belongs to the technical field of bridge construction. The bridge steel strand integral strand penetrating device comprises a rectangular sealing box body and further comprises a strand pulling conveying mechanism, wherein the strand pulling conveying mechanism is installed in the rectangular sealing box body and used for transmitting a plurality of cables at the same time and locking a strand penetrating head through a steel strand; the strand pulling conveying mechanism is installed in the rectangular sealing box body and is arranged in parallel with the strand pulling conveying mechanism to be in butt joint with the strand pulling conveying mechanism, multiple cables are connected to conduct synchronous strand conveying, the clamping locking mechanism is arranged on the outer side of a steel strand locking strand pulling head, and the steel strand locking strand pulling head is automatically and fixedly connected with the multiple cables. According to the invention, a plurality of steel strands sequentially penetrate from one end of the rectangular sealing box body, are connected and fixed by the steel strand locking and strand pulling head, and then are differently pulled by the strand pulling conveying mechanism, so strand pulling efficiency can be improved, bending can be avoided, the strand pulling length can be better controlled, and the cutting waste can be reduced.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to an overall threading device for bridge steel strands. Background technique [0002] Application of steel strands in bridges: steel strands are generally used in the upper structure of bridges, located inside the girder of the box girder, which can increase the span of the bridge and reduce the weight of the beam. [0003] In the steel strand threading construction, the single wire threading will cause the stranded wire to be entangled, causing uneven tension and uneven force. If the single thread is bent, the threading bundle needs to be replaced again, which is low in cost and efficiency. Therefore, we choose to adopt the method of threading the multi-stranded wires as a whole, but the overall threading needs to ensure that the pulling force of the finishing and threading is the same, and that the threading force of multiple stranded wires is the same to facilitate t...
