Embodiment Construction

[0061] The present invention will be further described below in conjunction with accompanying drawing.

[0062] Such as figure 1 and figure 2 As shown, an integral transport crawler-type multi-purpose mechanized fast over-obstacle bridge mainly includes bridge section one 6, bridge section two 7, middle bridge section 8, bridge section three 9, bridge section four 10, Overturn erection mechanism, horizontal hydraulic bolt 17, support mechanism and crawler bridge erecting vehicle 1.

[0063] Such as Figure 14 As shown, the crawler bridge erecting vehicle 1 is composed of a crawler chassis vehicle 21, a vehicle frame 22, a chassis stabilizing leg 16, a hydraulic system 23 and an electrical control system 24; the crawler bridge erecting vehicle 1 is used for the transportation and erection of the obstacle bridge . During erection, the crawler bridge erecting vehicle 1 is used as the intermediate support of the entire passage bridge; the hydraulic system 23 is used to drive ...

Abstract

The invention relates to an integrated transport track type multipurpose mechanized fast obstacle-surmounting bridge, and belongs to the field of mechanized bridges. In the obstacle-surmounting bridge, a first bridge section, a second bridge section, a third bridge section and a fourth bridge section are rotatably connected with a middle bridge section, unfolding and overturning are realized by anunfolding and overturning erection mechanism between the bridge sections, locking is realized by a transverse hydraulic inserting pin, and supporting is realized by a supporting mechanism at the bottom of the bridge sections; when the obstacle-surmounting bridge is not erected, the second bridge section and the middle bridge section are locked and arranged on a track frame bridge vehicle, and theremaining bridge sections are overlapped on the second bridge section and the middle bridge section; during erecting, the first bridge section, the third bridge section and the fourth bridge sectionrotate around all connecting points under pushing of the unfolding and overturning erection mechanism and are locked through the transverse hydraulic inserting pin after been unfolded to place; in theerection process, the supporting mechanism is extended to make contact with the ground for supporting; and after erection, the bridge sections and the track frame bridge vehicle are unlocked and separated, and the obstacle-surmounting bridge is formed. The obstacle-surmounting bridge adopts mechanized operation, a bridge for surmounting an obstacle can be erected quickly, road transporting requirements are met by integrated assembly, railway transporting requirements are met by split assembly, and supporting by the track frame bridge vehicle is not required after erection is completed.

Description

technical field [0001] The invention relates to an integral transport crawler-type multi-purpose mechanized fast barrier bridge, which belongs to the field of mechanized bridges. Background technique [0002] In the oil storage area of ​​the petrochemical industry, considering the requirements of fire protection, a fully enclosed fire dike is installed around the outside of each oil storage tank area, and there is no bridge for vehicles and other equipment to directly enter the tank area. The fire barriers have a certain height. When an emergency occurs in the tank farm, the repair vehicles cannot quickly cross these barriers, which seriously affects the repair time. Existing mechanized bridge technology does not have the function of crossing fire dike obstacles. The existing method is to use large cranes to hoist emergency repair vehicles into the tank area outside the fire dike of the oil depot tank area. This method is extremely inefficient. Contents of the invention ...
