Embodiment Construction
[0047] The present invention is described below in conjunction with accompanying drawing and implementation example:
[0048] Such as Figure 1-4 A modular all-terrain gantry crane shown includes a mobile column module, a beam module 2 , a sling 3 and a power module 4 . in:
[0049] The moving column module has a first moving column module 1 a and a second moving column module 1 b, and the first moving column module 1 a and the second moving column module 1 b respectively include a vehicle body 10 and a column arranged on the vehicle body 10 . In this embodiment: the vehicle body 10 includes a plurality of connected modular vehicles, such as a self-propelled modular transport vehicle (SPMT); the uprights are telescopic uprights 11 , such as through telescopic oil cylinders. The column holder 12 on the car body 10, the column holder 12 is positioned at both sides, the telescopic column 11 is positioned between the column holder 12 of both sides, and the bottom of the telescop...

The invention relates to a modular all-terrain gantry crane. The modular all-terrain gantry crane comprises movable upright post modules, a cross beam module, slings and a power module, wherein each movable upright post module comprises a vehicle body and a telescopic stand column, the telescopic stand columns are horizontally arranged on the vehicle bodies when the telescopic stand columns are ina first state; and when the telescopic stand columns are in a second state, the telescopic stand columns are vertically arranged on the vehicle bodies. A bridge floor dismantling method comprises thefollowing steps that the movable stand column modules are moved to the two sides of a bridge floor; the cross beam module is transported to the bridge floor; the movable stand column modules are connected with the two ends of the cross beam module; the slings are connected to the cross beam module and the bridge floor; and the telescopic stand columns are lifted, and the bridge floor is lifted and moved away. According to the modular all-terrain gantry crane, a modular structure is convenient to connect and dismount, capable of bring automatically transferred, flexible in movement, small in size and suitable for various types of places; the automation degree is high; and the gantry crane can be used in other transportation except for the bridge floor is dismantled, and the cost is effectively reduced.
Description
technical field [0001] The invention relates to a gantry crane, in particular to a modular all-terrain gantry crane; the invention also relates to the field of road and bridge construction, in particular to a bridge deck demolition method. Background technique [0002] Gantry crane (gantry crane) is a bridge-type crane whose bridge frame is supported on the ground or rails by outriggers on both sides. It is mainly used for loading and unloading operations of cargo yards, stock yards, and bulk cargoes. It has high site utilization and a large operating range. , wide adaptability, and strong versatility, it is widely used in port freight yards. [0003] Due to the large size of the gantry crane, it can only work in the set area after installation, and cannot move flexibly to adapt to various terrains, which limits its scope of use; in addition, the transfer after disassembly Also very cumbersome. [0004] Demolition of the bridge deck is a common construction in road and bri...
