A front outrigger structure of a highway bridge erection lifting device

Abstract

The invention relates to a front supporting leg structure of novel highway bridging hoisting equipment. The front supporting leg structure of the novel highway bridging hoisting equipment comprises a transverse moving rail. The left and right portions of the upper surface of the transverse moving rail are sequentially connected with a driven wheel box and a driving wheel box. The upper ends of the driving wheel box and the driven wheel box are both connected with saddle structures. The upper ends of the saddle structures are connected with a cross beam, and the left and right sides of the upper end of the cross beam are both connected with rotary supports. A pull rod A and a pull rod B are connected between lug plates, and a buffering mechanism is arranged in the connecting position of the pull rod A and the pull rod B. A sphere body is arranged in the middle of each rotary support, an oil storage chamber is arranged inside each sphere body, an upper semi-spherical shell is arranged on the upper side of each sphere body, and a lower semi-spherical shell is arranged on the lower side of the sphere body. A pressed Teflon sliding plate is arranged on the lower side of each lower semi-spherical shell, a stainless steel plate is arranged on the lower side of each pressed Teflon sliding plate, and an anti-drawing Teflon sliding plate is arranged in the middle of the connecting position of a sliding box and each upper semi-spherical shell. The front supporting leg structure of the novel highway bridging hoisting equipment has the advantages of being simple in structure, stable in operation, high in construction efficiency and convenient and rapid to operate.

Description

technical field [0001] The invention belongs to the technical field of hoisting equipment, and in particular relates to a front outrigger structure of hoisting equipment for road bridge erection. Background technique [0002] With the proposal and implementation of the grand development strategy of "One Belt, One Road" and "Maritime Silk Road", it will definitely bring a huge impetus to the development of countries and regions along the route. However, the infrastructure in various regions along the route is uneven. In particular, the weak infrastructure in some underdeveloped areas in the west will hinder various plans. Therefore, the premise of realizing this grand blueprint is to vigorously invest in and build infrastructure. In the process, road bridges and railway bridges must be There will be a lot of construction. In the construction process, bridge erecting equipment is an indispensable lifting equipment.

[0002] With the proposal and implementation of the grand development strategy of "One Belt, One Road" and "Maritime Silk Road", it will definitely bring a huge impetus to the development of countries and regions along the route. However, the infrastructure in various regions along the route is uneven. In particular, the weak infrastructure in some underdeveloped areas in the west will hinder various plans. Therefore, the premise of realizing this grand blueprint is to vigorously invest in and build infrastructure. In the process, road bridges and railway bridges must be There will be a lot of construction. In the construction process, bridge erecting equipment is an indispensable lifting equipment. The front outriggers of bridge erecting equipment are responsible for moving and supporting in the overall equipment, but most of the current front outriggers have structures It is more complicated, not stable enough during operation, and cannot meet the corresponding requirements of construction
