The utility model discloses the supporting leg is the telescopic structure, can guarantee the not construction of co -altitude, when the terrain clearance is if any the circumstances of unevenness in addition, also can adjust, the roll wheel that the supporting leg lower extreme set up has made things convenient for the removal of whole device, load -bearing platform comprises the carrier bar, has increased the intensity of device.
Description
Technical field
This utility model belongs to pipe canopy mounting technique field, is specifically related to surrounding rock tunnel pipe canopy erecting device.
Background technology
Barrel vault advanced support method is a kind of new technique carrying out tunnel piercing in weak rocks that developed recently is come in.Pipe shed method is a kind of householder method as constructing tunnel the earliest, passes through crushed zone, loose band, soft stratum in soft rock tunnel is constructed, and retention of excessive fluid, gushes layer of sand and has played important function.In tunnel excavation is constructed, enter entrance construction and typically beat locked anchor bar at hole periphery and carry out bursting work again, then carry out steel arch supporting.And tunneltron canopy plays in engineering is freely-supported beam action.Present tunneltron canopy is in construction process, due to the profile that it is fixing, it is impossible to enough regulate height, and can not move easily；Existing erecting device mostly is wooden material, and intensity is the highest, there is potential safety hazard.
Utility model content
The purpose of this utility model is to solve above problem, and provides surrounding rock tunnel pipe canopy erecting device.
This utility model be the technical scheme is that
nullA kind of surrounding rock tunnel pipe canopy erecting device，It is characterized in that: include carrying platform，Described carrying platform is rectangle，Several supporting legs it are provided with below carrying platform，Supporting leg is Collapsible structure，Described supporting leg upper end and carrying platform are flexibly connected，Supporting leg lower end is provided with scroll wheel，Head rod it is provided with between supporting leg and carrying platform，Described head rod is Collapsible structure，The bracing frame of at least two-layer it is provided with outside supporting leg，Described bracing frame includes connecting shaft and support bar，Bracing frame is connected by connecting shaft and supporting leg，Described connecting shaft is vertical with supporting leg，The second connecting rod it is provided with between bracing frame and supporting leg，Described second connecting rod is Collapsible structure，One end that the second described connecting rod is connected with bracing frame is provided with the first connector，One end that second connecting rod is connected with supporting leg is provided with the second connector，Carrying platform includes multiple carrier bar，Connect for fixing between described carrier bar，Carrying platform front end connects ladder.
Further, support frame as described above is two-layer.
Further, described carrying platform, supporting leg and bracing frame are steel.
Further, described ladder is extension ladder, ladder upper end and the fixing connection of carrying platform.
Further, described scroll wheel is universal wheel.
The beneficial effects of the utility model are: this utility model surrounding rock tunnel pipe canopy erecting device, supporting leg is telescopic structure, it is ensured that the construction of differing heights, when additionally ground level is if any irregular situation, it is also possible to be adjusted；The scroll wheel that supporting leg lower end is arranged, facilitates the movement of whole device；Carrying platform is made up of carrier bar, adds the intensity of device.
