In order to solve the technical problems, the technical scheme provided by the utility model is as follows: the utility model provides a fork ear formula suspension cable stretch-draw frock, includes: the device comprises an ear plate, a pull rod, a trapezoidal anchor clamp and a jack; the ear plate is provided with an anchor point, and one end of the steel cable can be fixedly connected with the ear plate through the anchor point; the pull rods are symmetrically arranged on two sides of the anchor point, and one end of each pull rod is arranged on the lug plate; the steel cable can penetrate through the center of the trapezoidal anchor clamp; the short side end of the trapezoidal anchor clamp faces the lug plate, and the long side end of the trapezoidal anchor clamp is provided with a jack; the other end of the pull rod penetrates through the trapezoidal anchor clamp and can be pulled by the jack.
The scheme is further improved in that: reaction holes symmetrically arranged are formed in two sides of the anchor point of the lug plate; one end of the pull rod is arranged on the lug plate through a fork lug and a pin shaft and a reaction hole.
The scheme is further improved in that: the trapezoidal anchor clamps are provided with truncated cone holes which can accommodate truncated cone-shaped sleeves on the steel cables.
The scheme is further improved in that: the pull rod is made of deformed steel.
The scheme is further improved in that: the pull rod can adjust the length.

Detailed Description
Examples
The tension tool for the fork-lug stay cable in the embodiment, as shown in fig. 1, comprises: the device comprises an ear plate 1, a pull rod 6, a trapezoidal anchor clamp 7 and a jack 8. The ear plate 1 is fixedly connected with a steel arch tower of the stay cable in advance, as shown in fig. 2, an anchor point 2 is arranged on the ear plate 1, and reaction force holes 3 are arranged on two sides of the anchor point 2. One end of the steel cable 9 is fixedly connected with the ear plate 1 through an anchor point. The reaction hole 3 is provided with a fork lug 5 through a pin shaft 4. The pull rods 6 are symmetrically arranged on two sides of the anchor point, and one end of each pull rod 6 is arranged on the lug plate 1 through the fork lug 5. The steel cable 9 passes through the center of the trapezoidal anchor clamp 7; the short side end of the trapezoidal anchor clamp 7 faces the lug plate 1, and the long side end is provided with a jack 8; the other end of the pull rod 6 passes through the trapezoidal anchor clamps 7 and is pulled by the jack 8.
As shown in fig. 3 to 5, the trapezoidal anchor clamps 7 are assembled from two components having the same shape and are fixed by bolts. The center of the trapezoidal anchor clamp is provided with a circular truncated cone hole for accommodating a circular truncated cone sleeve at the upper end part of the steel cable 9. Two other through holes are arranged on two sides of the round hole to accommodate the pull rod 6.
The pull rod 6 can be adjusted according to the length of the anchoring section of the fork ear type stay cable, and the relevant size of the trapezoidal anchor clamp 7 can be adjusted according to the diameter of the steel cable 9 and the outer diameter of the jack 8.
The ear plate 1 is a connection structure of the steel arch tower and the stay cable, the anchor point 2 is used for being connected with a fork ear pin of the stay cable, and the counter-force holes 3 on the two sides of the ear plate have the diameter of 7cm, so that the ear plate is convenient to adapt to tensioning of cable bodies with different space included angles. The tonnage of two jacks 8 is confirmed according to the design tension cable force, the trapezoidal anchor clamps 7 are used as front end limiting plates for tensioning operation, the twisted steel bars are used as pull rods 6, the diameter of the twisted steel bars is reasonably calculated, and the tension requirement is met. The front section of the pull rod 6 is provided with a fork ear 5 which has the same form and proper size with the front section of the stay cable, and the fork ears are connected with each other by welding.
