Abstract
The invention discloses a bridge-crossing assisting steel girder structure for a self-propelled modular transporter (SPMT) and a bridge-crossing method through the structure. The bridge-crossing assisting steel girder structure for the SPMT comprises a sliding module and two steel girder sets. The sliding module is arranged on the steel girder sets in a slidable mode, and the steel girder sets are arranged symmetrically. Each steel girder set comprises a bridge crossing steel girder and stress conversion girders connected to the two ends of the bridge crossing steel girder respectively. The bridge crossing steel girders are erected on a bridge, and roadbed cases are arranged at positions, in contact with a bridge roadbed, of the two ends of each bridge crossing steel girder. Roadbed cases are also arranged at positions where each bridge crossing steel girder and the corresponding bridge roadbed are in contact. An SPMT bridge crossing passage is arranged between the two steel girder sets. By means of the bridge-crossing assisting steel girder structure for the SPMT and the bridge-crossing method through the structure, the realistic feasibility of load sharing on the bridge of equipment for heavy parts by using an SPMT can be achieved, the load sharing design difficulty is reduced, and the bridge crossing method for the heavy parts is simplified.
Description
Technical field
The present invention relates to the bridge method excessively that a kind of SPMT transport vehicle is assisted gap bridge steel beam structure and used this structure.
Background technology
At present, when overweight car group is by bridge, bridge reinforcing method has following several: at the bottom plane of main girder sticking carbon fiber of bridge, can improve the intensity of bridge 25-30%, construct simple.Below bridge, arrange temporary bents reduce across footpath, because below bridge be river course, it is longer that be set the framed bent duration temporarily, not easily obtain approval or the agreement of vehicle supervision department.One interim " on bridge bridge " laid by former bridge, it is the method for current domestic normal use, prefabricated dismantled and assembled combined girder steel is laid on bridge, the deadweight of girder steel can increase the load of bridge pier, the principle of " on bridge bridge " technology be according to former bridge across footpath, girder steel is combined into a temporary bridge, be erected on original bridge, stress point is the buttress of former bridge, when heavy-duty vehicle passes through, the load suffered by buttress of girder steel two end is directly passed to ground, former bridge is not stressed or reasonable mechanical, improves the stressed of original bridge superstructure.Be suitable in solving, the problem of foot bridge " cross cart ".Shortcoming is the load that girder steel deadweight increases former bridge.By " waiting for load method " diagnostic method.Principle samely calculates overweight car across footpath (or load length) respectively with same effect string and standard vehicle equipollent load compares, and judges that can overweight car pass through, the need of consolidation process.Checking of bridge principle, for simple bridge, main checking computations span centre maximal bending moment, fulcrum shearing and bridge pier vertical force, wherein the most responsive and topmost problem mid span moment, design process is very complicated.
Summary of the invention
Technical problem to be solved by this invention is the defect overcoming prior art, a kind of SPMT transport vehicle is provided to assist gap bridge steel beam structure, it can solve the realistic feasibility that great good equipment use SPMT transports bridge load sharing in vehicle bridge, reduces load sharing design difficulty, simplifies great good and crosses bridge method.
The present invention solves the problems of the technologies described above the technical scheme taked: gap bridge steel beam structure assisted by a kind of SPMT transport vehicle, it comprises roll-off module and two groups of girder steel groups, roll-off module is slidably mounted in girder steel group, girder steel composition symmetry shape is arranged, often organize the stressed conversion beam that girder steel group comprises gap bridge girder steel and is connected to gap bridge girder steel two ends, gap bridge steel girder erection is on bridge, and the position that the two ends of girder steel of passing a bridge contact with bridge roadbed is provided with subgrade case, the position that described gap bridge girder steel and bridge roadbed contact also is provided with subgrade case, SPMT transport vehicle gap bridge passage is provided with between two groups of girder steel groups.
Further, gap bridge girder steel often hold 3 meters, the end growing corresponding bridge respectively.
Further, roll-off module comprises slide plate and slide block, and described slide block is arranged in girder steel group, and described slide plate is arranged on slide block.
Further, subgrade case is 10cm.
Present invention also offers a kind of bridge method excessively using this SPMT transport vehicle to assist gap bridge steel beam structure, the step of the method is as follows:
A (), according to the bridge design load in bridge design parameter and bridge length, determines length and the size of gap bridge girder steel and stressed conversion beam, and when determining to pass a bridge, the weight that the weight that SPMT transport vehicle carries and girder steel group carry;
B () utilizes the elevating function of SPMT transport vehicle, goods is unloaded on the roll-off module in girder steel group, SPMT transport vehicle slowly travels forward, drive goods from one end slippage of girder steel group to the other end, in this process, guaranteed the weight that weight that SPMT transport vehicle carries and gap bridge girder steel carry by SPMT transport vehicle;
C () utilizes the elevating function of SPMT transport vehicle after passing a bridge, rise goods, is removed by roll-off module, and transfers on SPMT transport vehicle by goods total weight, continues transport, thus completes gap bridge process.
After have employed technique scheme, the present invention can solve the realistic feasibility that great good equipment use SPMT transports bridge load sharing in vehicle bridge, reduces load sharing design difficulty, and it crosses bridge method simply, practical.
