Abstract
The utility model discloses a suspension bridge main cable erecting device which comprises a supporting frame, a carrier wheel supporting seat, a carrier wheel and a main cable rope arranged on the carrier wheel. The supporting frame comprises a supporting table provided with a limiting hole. The lower end face of the carrier wheel supporting seat is connected with a supporting rod with the lower end penetrating through the limiting hole. A spring is arranged between the carrier wheel supporting seat and the supporting table, wherein the supporting rod is sleeved with the spring. By the adoption of the structure, the suspension bridge main cable erecting device has the following advantages that through stretching and retraction of the spring, the carrier wheel supporting seat is driven to move vertically so that the main cable rope can be adapted to different heights; the phenomena that threads of the main cable rope are scattered and package winding belts are broken at the two sides of the top of a tower are reduced.
Description
Technical field
The utility model relates to a kind of main rope of suspension bridge stringer.
Background technology
Main cable strand, in when traction, when standing, has different height at tower top saddle's position, when adapting to different height, often occur main cable strand at tower top both sides filoselle, the phenomenons such as band fracture are wrapped.
Utility model content
Technical problem to be solved in the utility model is, for the deficiencies in the prior art, provides a kind of main rope of suspension bridge stringer that makes the differing heights that bracket can adapt to main cable strand.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of main rope of suspension bridge stringer, comprise bracing frame, support roller supporting seat, support roller, be arranged on the main cable strand on support roller, described bracing frame comprises brace table, described brace table is provided with spacing hole, on the lower surface of described support roller supporting seat, be connected with support bar, the lower end of described support bar, through described spacing hole, is provided with the spring being enclosed within outside support bar between described support roller supporting seat and brace table.
Described bracing frame also comprises frame bottom bearing, supports side arm, knighthead, and described brace table is arranged on and supports side arm top.
The utility model adopts said structure, has the following advantages: 1, by the flexible of spring, can drive support roller supporting seat to move up and down, make main cable strand can adapt to different height; 2, reduce main cable strand at the filoselle of tower top both sides, the phenomenons such as band fracture are wrapped.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
Fig. 1 is structural representation of the present utility model;
Fig. 2 is lateral view of the present utility model;
In Fig. 1～Fig. 2,1, support roller supporting seat; 2, support roller; 3, main cable strand; 4, brace table; 5, support bar; 6, spring; 7, bearing; 8, support side arm; 9, knighthead.
The specific embodiment
A kind of main rope of suspension bridge stringer as shown in Fig. 1～Fig. 2, comprise bracing frame, support roller supporting seat 1, support roller 2, be arranged on the main cable strand 3 on support roller 2, bracing frame comprises brace table 4, brace table 4 is provided with spacing hole, on the lower surface of support roller supporting seat 1, be connected with support bar 5, the lower end of support bar 5, through described spacing hole, is provided with the spring 6 being enclosed within outside support bar 5 between support roller supporting seat 1 and brace table 4.
Bracing frame also comprises frame bottom bearing 7, supports side arm 8, knighthead 9, between knighthead 9 and support side arm 8, is provided with crossbeam, plays a part to strengthen fixing.Brace table 4 is arranged on and supports side arm 8 tops.
In the time of need to reducing the height of main cable strand 3, spring 6 shrinks, and support bar 5 moves downward, and support roller supporting seat 1 moves downward, thereby drives support roller 2 to move downward, and main cable strand moves downward, and has reduced height; In the time of need to improving the height of main cable strand 3, spring 6 stretches, and support bar 5 moves upward, and support roller supporting seat 1 moves upward, thereby drives support roller 2 to move upward, and main cable strand moves upward, and has improved height; Main cable strand 3 of the present utility model can adapt to different height, widely applicable, reduce main cable strand 3 at the filoselle of tower top both sides, the phenomenons such as band fracture are wrapped.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as the various improvement that adopted the technical solution of the utility model to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
