Detailed Description
Example 1
Referring to fig. 1, an embodiment of the present invention provides an anti-slip reverse-pulling device for incremental launching construction, which mainly includes a reverse-pulling bracket 6 and a pulling device 4, wherein the pulling device 4 is fixed on a box girder 1, a pulling rope 5 is arranged on the pulling device 4, and the pulling device 4 can tighten or loosen the pulling rope 5 under manual control; the reverse pulling support 6 is arranged in the direction opposite to the sliding direction of the box girder 1, and the reverse pulling support 6 is aligned with the pushing temporary pier 2; the traction device 4 is connected with the reverse-pull bracket 6 through the traction rope 5, so that the distance between the box girder 1 and the reverse-pull bracket 6 can be controlled through the traction device 4 and the traction rope 5.
When the box girder is used, the traction rope 5 is firstly loosened by a certain length through the traction device 4 each time, then the box girder 1 is pushed by the walking jack 3 to move forwards on the pushing temporary pier 2 by a certain length, if the slipping phenomenon does not occur between the box girder 1 and the walking jack 3, the traction rope 5 is continuously loosened by a certain length through the traction device 4, and then the box girder 1 is pushed to move forwards through the walking jack 3. If the box girder 1 slides forwards on the walking jack 3, when the box girder 1 slides to the length of the released traction rope 5, the traction rope 5 is tightened, the box girder 1 stops sliding under the pulling force between the traction device 4 and the counter-pull bracket 6, so that a worker has an opportunity to adjust the pushing action of the walking jack 3 and the contact condition between the box girder 1 and the box girder 3, and the sliding problem between the box girder 1 and the walking jack 3 is solved.
Example 2
Referring to fig. 1, on the basis of embodiment 1, the traction device 4 is a winch, the traction rope 5 on the winch is generally a steel wire rope, the body of the winch is directly and fixedly connected to the box girder 1, one section of the steel wire rope is connected to the winch, the other end of the steel wire rope is connected to the counter-pull support, and the traction rope 5 can be easily controlled to be loosened and tightened by controlling the winch.
Example 3
Referring to fig. 1, on the basis of embodiment 2, the upper part of the box girder 1 is provided with embedded bolts, and the traction device 4 is fixedly connected to the box girder 1 through the embedded bolts. When the box girder 1 is poured, the embedded bolts are fixedly connected to the steel member of the box girder 1, and after the box girder 1 is poured, the traction device 4 is directly connected to the embedded bolts exposed out of the surface of the box girder 1, so that the tensile force applied to the traction device 4 can be directly transmitted to the box girder 1.
Example 4
Referring to fig. 1, on the basis of embodiment 1, a counter-pulling bracket 601 is arranged on the counter-pulling bracket 6, an anchoring seat 602 is arranged on the counter-pulling bracket 601, and the traction rope 5 is connected to the anchoring seat 602 through a rope buckle 603. The counter-pull bracket 601 is fixed on the top of the counter-pull bracket 6, the anchoring seat 602 is directly and fixedly connected with the steel bar structure inside the counter-pull bracket 6, and the traction rope 5 is tied up through the steel bar rope buckle 603 after bypassing the anchoring seat 602.
Example 5
Referring to fig. 1, on the basis of embodiment 4, the counter-pull bracket 601 includes a vertical frame and an oblique frame connected to the counter-pull bracket 6, the top of the vertical frame and the top of the oblique frame are fixedly connected to form a tripod structure with stability, and the anchor seat 602 is directly fixedly connected to the steel bar structure inside the vertical frame.
Example 6
Referring to fig. 1, in example 1, the traction direction of the stretched traction rope 5 is opposite to the sliding direction of the box girder 1. Thus, when the box girder 1 is about to slide, the traction force of the traction ropes 5, which are straightened, against the box girder 1 can just counteract the tendency of the box girder 1 to slide without causing the box girder 1 to move sideways.
Example 7
On the basis of any one of the above embodiments, the traction rope 5 is connected with a tension sensor, when the traction rope is tightened, the tension sensor can detect the tension on the traction rope 5, if the tension on the traction rope 5 exceeds a certain value, it indicates that the traction rope 5 is pulling the box girder 1 to prevent the box girder from slipping, and at this time, a worker is required to adjust the stress condition between the walking jack 3 and the box girder 1 to eliminate the slipping condition between the box girder 1 and the walking jack 3.
