Detailed Description

The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings to make it clear to those skilled in the art how to practice the invention. While the invention has been described in connection with its preferred embodiments, these embodiments are intended to be illustrative, and not to limit the scope of the invention.

Referring to fig. 1, the traction device without sag for the buckled anchor cable comprises an anchor 1, a buckled tower 2, a steering wheel 3, a supporting cable 4, a plurality of supporting cable rings 5, a connecting rope 6, a traction cable 7, a buckled anchor cable 8, a fastening buckle 9 and a winch 10.

The anchor 1 and the buckle tower 2 are both fixed on the ground, in actual implementation, the anchor 1 and the buckle tower 2 of the existing engineering can be both the anchor 1 and the buckle tower 2, and the top of the buckle tower 2 is provided with a steering wheel 3.

Two ends of the supporting cable 4 are respectively anchored at the positions, close to the tops, of the anchor block 1 and the buckling tower 2, the supporting cable 4 serves as a bearing cable, and a plurality of supporting cable rings 5 are hung on the supporting cable 4.

One end of the connecting rope 6, one end of the traction rope 7 and one end of the anchor buckle rope 8 are connected through a fastening buckle 9.

The connecting rope 6 connects the supporting cable rings 5 together in sequence, and the other end of the connecting rope 6 is connected with the anchorage 1; the traction rope is connected with a winch 10 by bypassing the steering wheel 3 at the top of the buckling tower 2, the winch 10 is arranged at the side of the buckling tower 2, and the winch 10 can be fixed with the ground or arranged on a movable trolley 11 so as to be convenient to move; and the buckling anchor cable 8 passes through the plurality of supporting cable rings 5 and is dragged on the ground at the side of the anchorage 1.

In operation, referring to fig. 1 and 2, the winch 10 operates to pull the connecting rope 6 and the anchor fastening rope 8 through the pulling rope, the plurality of supporting cable rings 5 move along the supporting rope 4 under the driving of the connecting rope 6, and support the pulled anchor fastening rope 8, so that the non-sag pulling construction of the anchor fastening rope 8 is realized.

The material and diameter of all ropes, the size of the structural members and the connection are determined by calculation according to actual conditions. Taking a large-scale arch bridge project in a certain mountain area as an example, the arch axis of the steel arch rib is in a catenary shape, the air inclination angle and the posture of each section are different, the maximum weight of a single section is 150t, and anchor cables on two banks span the existing provincial road. When steel arch rib segment site lifting adopts the oblique pull to detain the cantilever concatenation method of hanging to install, adopts the utility model discloses detain anchor rope 8 and do not have the sag traction device and carry out the non-sag of arch rib knot anchor rope 8 and pull the construction, solved smoothly because of the anchor rope pulls the too big condition that influences the traffic of sag in the work progress. The supporting rope 4 is a phi 26 steel wire rope (6 multiplied by 37S + FC), the supporting rope ring 5 is an iron ring with the diameter of 20cm, the connecting rope 6 is a phi 12 common steel wire rope, the traction rope 7 is a phi 12 common steel wire rope, the buckling anchor rope 8 is a phi 15.24 steel stranded wire, the steering wheel 3 is a 5t steering wheel 3, the winch 10 is a 5t single-barrel winch 10, and the fastening buckle 98 is a 3t small-sized buckle.

It should be noted that many variations and modifications of the embodiments of the present invention are possible, which are fully described, and are not limited to the specific examples of the above embodiments. The above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. In conclusion, the scope of the present invention should include those changes or substitutions and modifications which are obvious to those of ordinary skill in the art.
