Description
Technical field
Safety protecting work trolley for chamber belongs to large-scale hydroelectric project underground cavern excavation security protection facility.
Background technology
Large-scale hydroelectric project underground cavern excavation work plane is complicated and changeable, exists bigger operating risk.At present, even if just becoming in the large-scale hydroelectric project underground cavern excavation construction of trend in mechanization of building operation, jumbo, rock bolting jumbo, whitewashing chassis also fail to cover whole work planes of whole caverns, steel bow member, steel mesh reinforcement construction still must manual type be implemented to finish in addition, so design and produce construction installation, be equipped in ubiquity in the engineering at cavern's manual work.Existing this class construction installation of cavern's operation chassis, device, generally only be thought of as a kind of temporory structure or device (odd-job stand), make at a certain specific cavern or particular requirement temporarily, mostly be and gather materials on the spot, build temporarily, do not go deep into comprehensive research newly the dig a hole security risk and the job requirements of chamber construction operation, design arbitrarily, thin, the function singleness of structure, transfer difficulty, in various degree have that the security protection level is on the low side, the relatively poor technological deficiency of construction usefulness.
Summary of the invention
The problem to be solved in the present invention is exactly that a kind of cavern excavation supporting construction overall process, construction operation flexible, that have higher safety and Protection level protection chassis are provided at above deficiency.Its technical scheme is as follows:
It comprises protection canopy, job platform, adjusting device and mobile device, protection canopy by upright supports on mobile device.Its key technology is that protection canopy mainly is made up of protection roof truss and expanded metal lath, the protection roof truss comprises horizon bar, vertical rod and brace, the end to end top that is fixed on column of horizon bar, the fixed vertical bar is distinguished at the middle part of two horizon bars parallel to each other therein, between the both ends of the top of vertical rod and horizon bar, brace is installed respectively, constitute and to have the domatic protection roof truss of symmetry, on protection roof truss domatic, grid is installed, expanded metal lath is installed on the grid.Job platform comprises upper mounting plate, middle platform and scaling platform, upper mounting plate is located on the horizon bar, middle platform two ends mounting platform hoist cylinder, and the piston rod of lifting platform oil cylinder is installed in the upper mounting plate two ends, establish scaling platform respectively at middle platform two ends, establish folding platform respectively at column lower end.
Compared with prior art, the beneficial effect that has of the present invention is:
1, the tubing string of column can stretch, and can arbitrarily adjust the height of upper mounting plate and protection canopy, and scaling platform and folding platform act freely, and makes chassis of the present invention be applicable to cavern excavation supporting construction overall process, and compliance is strong.
2, when upper load surpassed safe load, the column hoist cylinder bounced back automatically, and scaling platform rises.At this moment, column is that two endowels and oil cylinder are born load jointly, effective transmission of succinct distinct chassis load, improved the supporting capacity of column greatly, make the Waiting space that causes below the platform greater than more than the 2.5m, have higher safety and Protection level, improved the security protection ability, greatly reduce cavern's operating risk.
3, by adjusting device protection canopy and hole summit curve are matched, structure is flexible and changeable, can adapt to different caverns and working condition requirement.
4, sled has ground conformability preferably, adapts to the needs that pull displacement in the chassis hole.
