Description
Technical field
The utility model relates to pattern foundation pit supporting structure Demolishing Technology field, particularly a kind of fork truck supporting pattern foundation pit supporting structure dismounting for large-span steel.
Background technology
In prior art, the general most high energy of fork truck lifts 2.7 meters, but the height in large-span steel support pattern foundation pit supporting structure Demolition Construction between raft plate and inner support steel pipe is far more than 2.7 meters, and special fastening complex structure, cost are high and be not suitable for the narrow and small workyard of foundation ditch, therefore construction requirement can not be met.
Utility model content
The utility model provides a kind of fork truck for removing inner support steel pipe, object is that solving large-span steel supports in pattern foundation pit supporting structure dismounting, in prior art, requirement removed by fork truck bearing height out of reach internal support of foundation pit steel pipe, and other special fastening complex structure, cost are high and be not suitable for the problem of the narrow and small workyard of foundation ditch.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of fork truck for removing inner support steel pipe, comprise car body, hoofing part mechanism and lifting mechanism, described lifting mechanism comprises door frame, L shape pallet fork and the hydraulic ram as the power plant that hoists, it is characterized in that: the bottom welding of described L shape pallet fork has the riser being used for for a pair increasing fork truck maximum support height, described riser measure-alike and parallel to each other, described in it, the right angle portions of riser is close to the kink of steel fork, width is shorter than the length of steel fork sweep, the top uniform collapse camber groove of described riser, the diameter of arc groove and the diameter of inner support steel pipe to be removed adapt, support is welded with between described riser.
Describedly be supported for strut bar or stay bearing plate.
Describedly be supported for bridging or horizontal diagonal brace.
Compared with prior art, technical advantage of the present utility model is: provide and propose a kind of dismounting fork truck, add bearing height and structure is simple, easy to operate, solve fork truck bearing height inner support steel pipe in prior art and remove requirement, simultaneously other fastening complex structures, cost are high and be not suitable for the problem of the narrow and small workyard of foundation ditch, for construction provides conveniently, are specially adapted to the dismounting that large-span steel supports pattern foundation pit supporting structure.

Detailed description of the invention
As Fig. 1 ~ 2, a kind of fork truck for removing inner support steel pipe, comprise car body 91, hoofing part mechanism and lifting mechanism 95, described lifting mechanism 95 comprises door frame, L shape pallet fork 92 and the hydraulic ram as the power plant that hoists, it is characterized in that: the bottom welding of described L shape pallet fork 92 has the riser 93 being used for for a pair increasing fork truck maximum support height, described riser 93 measure-alike and parallel to each other, the right angle portions of described riser 93 is close to the kink of steel fork, width is shorter than the length of steel fork sweep, the top uniform collapse camber groove 94 of described riser 93, the diameter of arc groove 94 and the diameter of inner support steel pipe 1 to be removed adapt, support 96 is welded with between riser 93, supporting 96 can be strut bar or stay bearing plate, can be bridging or horizontal diagonal brace.,
Fig. 3 is inner support penstock installation schematic diagram in the inner support system that relates to of the utility model; Fig. 4 is the structural representation of the inner support steel pipe 1 that the utility model relates to; Fig. 5 is the schematic diagram of the dismounting inner support steel pipe related in the utility model, and the concrete use step that the utility model fork truck is mainly used in inner support steel pipe dismounting in plane is as follows:
Dismounting fork truck 9 winches on raft plate 6 by foundation ditch limit by step 1, use tower crane 7;
Step 2, inner support steel pipe 1 is horizontally placed in the arc groove 94 of fork truck, starts and remove fork truck 9 and coordinate electric block 11 or tower crane 7 to hold power to dismounting component;
Step 3, hang steel pipe support with tower crane 7;
Step 4, ecto-entad remove steel pipe support: add force compresses with hydraulic jack pair of interior support steel pipe 1, remove gad 12, shed steel shaft power 13, remove annex such as fixing steel plate 14 grade to the constraint of steel pipe support, remove in the middle part of inner support steel pipe to connecting bolt 11, and remove the inner support steel pipe of dismounting part;
Step 5, turn the direction of steel pipe support, make it drop on to remove on fork truck 9 to be transported to interim all turning points;
Step 6, dismounting tie-rod 5: tie-rod 5 is the bearing of steel pipe support, treat that steel pipe support removes complete can dismounting, available gas welding disconnects rear segmentation and directly transports by removing fork truck 9.
