Description
Technical field
This utility model belongs to protecting device for tunnel construction technical field, is specifically related to a kind of lift tunnel construction protection canopy.
Background technology
In constructing tunnel process, it is frequently necessary to the construction such as carpenter, reinforcing bar, stirring, these operations are typically all and carry out near building, in the work progress near building, it is likely at any time from aerial dropped object, workmen be damaged, damages construction equipment.In order to accomplish safe construction, at present, construction site is generally adopted the welding of the material such as steel pipe, angle steel and makes framework, the protective plates such as plank are put on the top of framework, make easy protection canopy, this protection canopy has the disadvantage in that 1, needs to adopt welding and welding in installation and removal process, and labor intensity is big；2, protection canopy height is fixed, and is not easy to clean out the rubbish dropping on protection canopy end face, is also not easy to pick up the construction equipments such as the crash helmet that by mistake drops on protection canopy end face.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, it is provided that a kind of lift tunnel construction protection canopy, it have safe and reliable, be easy to regulate the features such as height.
nullThis utility model be the technical scheme is that a kind of lift tunnel construction protection canopy，Including steel structural roof and be installed on the framework below above-mentioned steel structural roof，Described steel structural roof is by the steel wire of braided steel wire，It is provided with buffer spring between described framework and described steel structural roof，One end of described buffer spring is fixing with described framework to be connected，Its other end is fixing with described steel structural roof to be connected，Described framework is by the many columns being arranged side by side and is made up of the top board of this upright supports，Described cover top surface center is provided with rotation gear，Described top board corner location is provided with four band teeth nuts being in transmission connection by travelling gear and described rotation gear，Described top board is equipped with and the above-mentioned elevating screw consistent with teeth nut quantity，The upper end of described elevating screw runs through described with on the lower surface being fixedly connected on described steel structural roof after teeth nut correspondingly，Described top board is run through in the lower end of described elevating screw.
As preferably, described rotation gear is rotated by rotary electric machine, and the control knob of described rotary electric machine is disposed therein the medium position of a column.
The beneficial effects of the utility model are in that: owing to the steel wire of this utility model steel structural roof has good elasticity, and buffering effect is desirable, it is ensured that the safety of workmen and equipment；Elevating screw allows to control easily the oscilaltion of steel structural roof, it is easy to user and cleans out the rubbish dropping on protection canopy end face, also allow for picking up the construction equipments such as the crash helmet that by mistake drops on protection canopy end face, control to rotate gear to rotate, drive elevating screw to move up and down by band teeth nut, namely realize the oscilaltion operation of steel structural roof.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, steel structural roof；2, buffer spring；3, column；4, top board；5, gear is rotated；6, band teeth nut；7, travelling gear；8, elevating screw.
Detailed description of the invention
Below in conjunction with the accompanying drawings and the specific embodiments this utility model is described in further detail.
nullAs shown in Figure 1，A kind of lift tunnel construction protection canopy，Including steel structural roof 1 be installed on the framework below above-mentioned steel structural roof 1，Described steel structural roof 1 is by the steel wire of braided steel wire，Buffer spring 2 it is provided with between described framework and described steel structural roof 1，One end of described buffer spring 2 is fixing with described framework to be connected，Its other end is fixing with described steel structural roof 1 to be connected，Described framework is made up of the many columns being arranged side by side 3 and the top board 4 that supported by this column 3，Described top board 4 upper surface center is provided with rotation gear 5，Described top board 4 corner location is provided with four band teeth nuts 6 being in transmission connection by travelling gear 7 and described rotation gear 5，Described top board 4 is equipped with and the above-mentioned elevating screw 8 consistent with teeth nut 6 quantity，The upper end of described elevating screw 8 runs through described with on the lower surface being fixedly connected on described steel structural roof 1 after teeth nut 6 correspondingly，Described top board 4 is run through in the lower end of described elevating screw 8.
Owing to the steel wire of this utility model steel structural roof 1 has good elasticity, buffering effect is desirable, it is ensured that the safety of workmen and equipment；Elevating screw 8 allows to control easily the oscilaltion of steel structural roof 1, it is easy to user and cleans out the rubbish dropping on protection canopy end face, also allow for picking up the construction equipments such as the crash helmet that by mistake drops on protection canopy end face, control to rotate gear 5 to rotate, drive elevating screw 8 to move up and down by band teeth nut 6, namely realize the oscilaltion operation of steel structural roof 1.
It addition, described rotation gear 5 is rotated by rotary electric machine, and the control knob of described rotary electric machine is disposed therein the medium position of a column 3, it is simple to user operates.
The above, it is only this utility model preferred embodiment, therefore can not limit, with this, the scope that this utility model is implemented, the equivalence namely made according to this utility model claim and description changes and modifies, and all should still belong in the scope that this utility model patent contains.
