Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bridge erecting device, in particular to a single-double-line adaptive transport-erecting integrated bridge erecting machine and its using method. BACKGROUND

[0002] In recent years, with the development of high-speed railway construction to mountainous areas, the bridge erection in these areas often encounters the construction conditions of both 500t single-line beam and 700t-900t double-line beam, which requires two different bridge erecting machines to meet the construction requirements. The traditional transport-erecting separated bridge erecting machine and the transport-erecting integrated machine cannot adapt to the single beam type, and cannot meet the needs of the multi-beam type construction conditions.

[0003] Therefore, it is necessary to design a bridge erecting machine that can meet the needs. SUMMARY

[0004] The technical problem to be solved by the present application is to provide a single-double-line adaptive transport-erecting integrated bridge erecting machine and its using method, which overcomes the single function of the existing bridge erecting machine that can only meet the single-line or double-line bridge erection, thereby providing a transport-erecting integrated bridge erecting machine that can simultaneously adapt to single-line and double-line bridge erection conditions.

[0005] The technical problem to be solved by the present application is solved by the following technical scheme:

[0006] One object of the present application is to provide a single-double-line adaptive transport-erecting integrated bridge erecting machine, comprising:

[0007] A main beam for supporting the bridge erecting machine structure;

[0008] A front vehicle and a rear vehicle connected to the front and rear ends of the main beam respectively for walking of the bridge erecting machine;

[0009] A front hoisting crane and a rear hoisting crane connected to the front and rear ends of the main beam respectively and located between the front vehicle and the rear vehicle for erecting a bridge;

[0010] A main leg movably connected to the main beam through a hanging wheel system arranged on the upper part of the main leg;

[0011] An auxiliary leg arranged in front of the front hoisting crane for temporary support of the bridge erecting machine leg reversing operation;

[0012] A lifting system arranged at the rear end of the main beam for lifting and moving the bridge structure.

[0013] Preferably, the main beam adopts a layered structure, and a reinforcing layer is arranged on the upper part of the main beam, and the reinforcing layer is connected to the main beam through bolts.

[0014] Preferably, the upper crossbeam of the front vehicle is equipped with an automatic wheel track lateral adjustment device to adapt to the erection of bridges of different widths.

[0015] Preferably, both the upper crossbeam of the rear vehicle and the upper crossbeam of the auxiliary support leg are provided with two types of installation interfaces to adapt to the erection requirements of different types of bridges.

[0016] Preferably, the two mounting interfaces are an external mounting interface and an internal mounting interface.

[0017] Preferably, the main support leg has a triangular structure and can travel along the main beam via the roller system.

[0018] Another objective of this application is to provide a method for using an integrated bridge erecting machine suitable for single and double lines, comprising the following steps:

[0019] (1) When erecting 700t-900t double-track box girders, the construction method includes the following steps:

[0020] A1. Install the upper reinforcing layer on the main beam to improve its strength;

[0021] A2. The rear vehicle is installed on the outer side of the upper crossbeam with an interface;

[0022] A3. The auxiliary support leg is installed on the outer side of the upper crossbeam through the mounting interface;

[0023] A4. The front vehicle uses the automatic wheel track lateral adjustment device to push the trolley to the outside along the upper crossbeam;

[0024] To ensure that all components are adapted to the requirements of double-track box girder erection, the construction steps are the same as those of mobile bridge erection machines.

[0025] (2) When erecting a 500t single-track box girder, the construction method includes the following steps:

[0026] B1. Remove the upper reinforcing layer from the main beam to reduce its weight;

[0027] B2. The rear vehicle is installed on the inner side of the upper crossbeam with an interface;

[0028] B3. The auxiliary support leg is installed on the inner side of the upper crossbeam through the mounting interface;

[0029] B4. The front vehicle uses the automatic wheel track lateral adjustment device to pull the trolley along the upper crossbeam to the inside;

[0030] To ensure that all components are adapted to the requirements of single-line box girder erection, its construction steps are the same as those of a double-line mobile bridge erection machine.

[0031] Preferably, when erecting a single-line box girder, during the second heavy-load crossing of the pier under the joint drive of the main support leg constant torque motor and the rear vehicle, the main support leg needs to pass through the front vehicle. At this time, the front vehicle pushes the trolley along the upper crossbeam to the outside through the wheel track lateral automatic adjustment device in the air to ensure that the main support leg passes through smoothly. After the box girder is erected in place, the machine stops moving and the girder is lowered into place.

[0032] Preferably, after the box girder is in place, the entire machine reverses. Once the lead vehicle returns to the bridge deck, the trolley is pulled to the inside along the upper crossbeam by the automatic wheel track lateral adjustment device, the main support legs are retracted, and the entire machine returns to the beam yard. The erection of this span of the beam is completed, and preparations are made for the next cycle of operation.

[0033] The above-described technical solution of the present invention has the following beneficial effects:

[0034] (1) The bridge erecting machine adapted to single and double lines of this application can achieve multiple uses by improving the structure of the original mobile bridge erecting machine and making simple modifications, so as to meet the construction of 500t single-line beams and 700t-900t double-line beams of high-speed railway bridges.

[0035] (2) Using the bridge erecting machine of this application to carry out bridge erection in multi-beam sections is safe, reliable, and easy to control in terms of quality. It can also reduce economic costs, save construction time to the greatest extent, and enable a high-speed railway to be completed and opened to traffic more quickly, creating great national economic benefits.

The two types of mounting interfaces are the outer mounting interface 14 and the inner mounting interface 15.

[0059] Furthermore, the main support leg 4 has a triangular structure, which can travel along the main beam 1 via a roller system.

[0060] The bridge erecting machine of this application, which is adapted to both single and double tracks, can be easily modified to achieve multiple uses, meeting the needs of bridge erection for 500t single-track beams and 700t-900t double-track beams of high-speed railway bridges. The specific usage method is as follows:

[0061] (1) When erecting 700t-900t double-track box girders, the construction method includes the following steps:

[0066] (like Figure 4 , Figure 5 (As shown).

[0067] To ensure that all components are adapted to the requirements of double-track box girder erection, the construction steps are the same as those of the original mobile bridge erection machine.

[0068] (2) When erecting a 500t single-track box girder, the construction method includes the following steps:
