The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1, 2 and 3, a self-anchored suspension bridge construction auxiliary device, a cable tower 3 of the suspension bridge is disposed on a bearing platform 7, a construction hoist 2 is disposed at left and right side positions of the cable tower 3, the construction hoist 2 corresponds to a base 8, the base 8 is disposed on an auxiliary platform of a trestle beside the bearing platform 7, the construction hoist 2 is a single-cage construction hoist, for example, a hoist with a model of SC200G, the standard section specification of the construction hoist is 650 × 650 × 1508mm, and the construction hoist corresponds to a cage with a dimension of 3.2 × 1.5 × 2.5m, and the construction hoist and cage structure is a common structure, which will not be described herein. The bearing platform 7 is provided with a steel upright 1 at a position between the construction hoist 2 and the cable tower 3, and the steel upright 1 is fixed on the bearing platform 7 by anchor bolts, as shown in fig. 4. In this embodiment, the pylon 3 is a variable cross-section pylon and includes a lower pylon 31 and an upper pylon 32 disposed thereon, the cross-sectional area of the upper pylon 32 gradually increases from top to bottom, the cross-sectional area of the lower pylon 31 gradually decreases from top to bottom, that is, the width of the lower pylon 31 gradually decreases from top to bottom, the width of the upper pylon 32 gradually increases from top to bottom, and the connection position of the lower pylon 31 and the upper pylon 32 is the maximum position of the cross-sectional area of the pylon 3. The height of the steel upright 1 corresponds to that of the lower cable tower 31. Construction elevator 2 corresponds the part through a plurality of first connecting pieces 4 and the steel stand 1 fixed connection that from top to bottom set up in order and equidistance with steel stand 1, for example every two adjacent first connecting pieces 4 interval 6 meters set up. The part of the construction lifter 2, which is higher than the steel upright post 1, is fixedly connected with the cable tower 3 through a plurality of third connecting pieces 6 which are sequentially arranged from top to bottom and are arranged at equal intervals. In this embodiment, the first and third connecting members 6 are II-shaped wall-attached frames, respectively.

For the convenience of construction, the construction lifter 2 is obliquely arranged in the direction of the cable tower 3 at an angle of 85-87 degrees with the horizontal plane.
