Therefore, a feature defined as "one" or "two" may explicitly or implicitly include at least one of the features. In the description of the present invention, "multiple" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0034] In the embodiments of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0035] like Figure 1-5 As shown, a traveling mechanism of a suspension bridge erecting machine is provided, which is composed of an anti-torsion component 101, an anti-torsion component 102, an outrigger beam 201, an outrigger beam 202, a load transfer cylinder 301, a load transfer cylinder 302, a main cable 4, a traveling box 501, a traveling box 502, a cable clamp 1 601, a cable clamp 2 602, a cable clamp 3 603, a clamp 1 701 with a longitudinal constraint, a clamp 2 702 with a heavy-load support seat, a clamp 3 703 with a heavy-load support seat, a position adjustment component 8, an anchor 1 9, an anchor 2 10, a steel strand jack 11 at the uphill end, a steel strand jack 12 at the downhill end, a longitudinal beam 13, a pin connector 14 and the like.

[0036] The two ends of the longitudinal beam 13 along the direction of the main cable 4 are fixedly connected to the cantilever beam 1 201 and the cantilever beam 2 202 respectively.

[0037] The roller of the running box 1 501 is supported on the main cable 4, an anti-torsion assembly 101 is hinged between the longitudinal beam 13 and the running box 1 501, and a load transfer cylinder 1 301 is hinged between the cantilever beam 1 201 and the running box 1 501. The roller of the running box 2 502 is supported on the main cable 4, an anti-torsion assembly 2 102 is hinged between the longitudinal beam 13 and the running box 2 502, and a load transfer cylinder 2 302 is hinged between the cantilever beam 202 and the running box 2 502.

[0038] like Figure 2 and 3 As shown, the load transfer cylinder 301 (equivalent to Figure 4 L3 in), anti-torsion component 101 (equivalent to Figure 4 L2 in the figure) and the cantilever beam 201 (equivalent to Figure 4 The three of them form an angle-changing triangle. Load transfer cylinder 2 302 (equivalent to Figure 4 L3 in), anti-torsion component 102 (equivalent to Figure 4 L2 in the figure) and the cantilever beam 202 (equivalent to Figure 4 The three of them constitute an angle-changing triangle. The load transfer cylinder 1 301 and the load transfer cylinder 2 302 only bear axial force, and their length can be adjusted. The adjustment range of their cylinder strokes satisfies the changes in the side lengths of different angle-changing triangles, that is, they meet the needs of practical applications. The extended lengths of the load transfer cylinder 1 301 and the load transfer cylinder 2 302 are different. Therefore, the lengths of L3 of the left and right angle-changing triangles are different, which ensures that the running mechanism can form a stable triangular connection with the longitudinal beam 13 in both heavy-load and no-load modes. The anti-torsion component of the angle-changing triangle is a frame structure that can resist horizontal forces; the cantilever beam adopts a box-shaped structure that can resist horizontal forces; the anti-torsion component and the cantilever beam are connected to the longitudinal beam 13 to ensure the overall rigidity of the running mechanism.

[0039] The longitudinal beam 13 is clamped and connected to the main cable 4 through a clamping assembly arranged at the bottom. Specifically:

[0040] The clamping assembly includes a clamping member 1 701 with a longitudinal constraint, a clamping member 2 702 with a heavy-load support seat, and a clamping member 3 703 with a heavy-load support seat. The clamping member 2 702 with a heavy-load support seat and the clamping member 3 703 with a heavy-load support seat are respectively arranged at both ends of the longitudinal beam 13 and installed on the main cable 4. The position of the clamping member 1 701 with a longitudinal constraint on the longitudinal beam 13 is adjusted by sliding through the position adjustment assembly 8. The clamping member 1 701 with a longitudinal constraint is installed on the main cable 4 and is pressed against the cable clamp 1 601 on the main cable 4.

[0041] The clamping member in the clamping member 701 with longitudinal restraint can clamp or loosen the main cable 4, and the longitudinal restraint cooperates with the cable clamp 601 of the main cable 4 to maintain the longitudinal position. It should be noted that in this embodiment, the longitudinal restraint is not within the protection scope of the present utility model, so the specific structure of the longitudinal restraint is not described in detail in this embodiment, and the specific structure of the longitudinal restraint will not affect the specific implementation of the technical solution of the present utility model, and is only used for those skilled in the art to understand that the clamping member has the longitudinal restraint function.

[0042] The clamping member of the clamping member 2 702 with a heavy-load support seat or the clamping member 3 703 with a heavy-load support seat can clamp or loosen the main cable 4, and the heavy-load support seat cooperates with the main cable 4 to provide support. It should be noted that in this embodiment, the heavy-load support seat is not within the protection scope of the present utility model, and therefore, the specific structure of the heavy-load support seat is not described in detail in this embodiment, and the specific structure of the heavy-load support seat will not affect the specific implementation of the technical solution of the present utility model, and is only used for those skilled in the art to understand that the clamping member has a supporting function.

[0043] The cantilever beam 1 201 is hinged with a steel strand jack 12 at the downhill end. The cantilever beam 202 is hinged with a steel strand jack 11 at the uphill end. The power of the running mechanism of the utility model is to pull the steel strand jack 11 at the uphill end and the steel strand jack 12 at the downhill end to provide traction during the running of the bridge erecting machine.

[0044] Further, the steel strand jack 11 at the uphill end is connected to the anchor 1 9 through the steel strand, and the anchor 1 9 is sleeved and installed on the main cable 4 and is pressed against the cable clamp 2 602 on the main cable 4. The cable clamp 2 602 is fixedly installed on the main cable 4. The steel strand jack 12 at the downhill end is connected to the anchor 2 10 through the steel strand, and the anchor 2 10 is sleeved and installed on the main cable 4 and is pressed against the cable clamp 3 603 on the main cable 4. The cable clamp 3 603 is fixedly installed on the main cable 4.

[0045] like Figure 1 and 5 As shown, a pin connector 14 is fixedly installed on the longitudinal beam 13, and the pin connector 14 is hinged with a main truss 15, and the bottom of the main truss 15 is connected to a lifting mechanism 7. A hand-operated hoist 1601 and a hand-operated hoist 2 1602 are respectively installed between the main truss 15 and the longitudinal beam 13 on both sides along the direction of the main cable 4.

[0046] The longitudinal beam 13 is connected to the main truss 15 by a pin shaft. When the suspension bridge erecting machine is at different positions of the main cable 4, the main truss 15 and the lifting mechanism 17 can be kept vertical, ensuring the safety of the operation when the beam section is erected and the whole machine is moved. By adjusting the length of the chain of the hand-operated hoist 1 1601 and the hand-operated hoist 2 1602, the main truss 15 is prevented from shaking when the whole machine is moved or under the action of strong wind, ensuring the safety and reliability of the suspension bridge erecting machine when the whole machine is moved and parked on the main cable.

[0047] In summary, when the bridge erecting machine is overloaded, the clamping piece 2 702 with the heavy-load support seat and the clamping piece 3 703 with the heavy-load support seat are supported on the main cable 4, the load transfer cylinder 1 301 and the load transfer cylinder 2 302 are contracted, and the rollers of the running box are clear of the surface of the main cable 4. When the bridge erecting machine is unloaded and shifted, the load transfer cylinder 1 301 and the load transfer cylinder 2 302 are extended, the rollers of the running box are supported on the main cable 4, the clamping piece 2 702 with the heavy-load support seat and the clamping piece 3 703 with the heavy-load support seat are loosened, and the steel strand jack 11 at the uphill end and the steel strand jack 12 at the downhill end pull the whole machine to shift.

[0048] The working process of this embodiment will be further described below:

[0049] When the suspension bridge erecting machine lifts the beam section, the load transfer cylinder 1 301 and the load transfer cylinder 2 302 are retracted, the rollers of the running box 1 501 and the running box 2 502 are detached from the main cable 4, the longitudinal restraint of the clamping member 1 701 with longitudinal restraint is pressed against the cable clamp 1 601 of the main cable 4, and the clamping member clamps the main cable 4; the clamping member 2 702 with heavy-load support seat and the heavy-load support seat of the clamping member 3 703 with heavy-load support seat are supported on the main cable, and the clamping member clamps the main cable 4. By adjusting the length of the chain of the lever hoist 1 1601 and the lever hoist 2 1602, the main truss 15 and the lifting mechanism 17 are made vertical, and the lifting mechanism 17 starts to lift the beam section.

[0050] After a beam section is erected, the clamping parts of the clamping parts 2 702 with heavy-load support seat and the clamping parts 3 703 with heavy-load support seat are loosened, the load transfer cylinder 1 301 and the load transfer cylinder 2 302 are extended, the rollers of the running box 1 501 and the rollers of the running box 2 502 are supported on the main cable, the anchor 1 9 is pressed against the cable clamp 2 602, the clamping parts of the clamping parts 1 701 with longitudinal restraints are loosened, the steel strand jack 11 at the uphill end and the steel strand jack 12 at the downhill end cycle, and the suspension bridge erection machine moves to the next hoisting position. Use the position adjustment component 8 to adjust the position of the clamping parts 1 701 with longitudinal restraints on the longitudinal beam 13 of the running mechanism so that it is pressed against the edge of the cable clamp 1 601.

[0051] When the suspension bridge erecting machine moves to the middle of the main cable 4 span for downhill operation, the angle of the main cable is small, and the gravity of the erecting machine alone is insufficient to overcome the friction. By setting the steel strand jack 12 at the downhill end, the anchor 2 10 and the cable clamp 3 603 are tightened, and the steel strand jack 11 at the uphill end and the steel strand jack 12 at the downhill end circulate to pull the suspension bridge erecting machine into operation.

[0052] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any technician familiar with the field can make many possible changes and modifications to the technical solution of the utility model by using the above disclosed methods and technical contents without departing from the scope of the technical solution of the utility model, or modify it into an equivalent embodiment of equivalent changes. Therefore, all equivalent changes made according to the shape, structure and principle of the utility model without departing from the content of the technical solution of the utility model should be included in the protection scope of the utility model.
