Problems solved by technology
With the continuous deepening of tunnel excavation, it takes a lot of time to drive the trolley into place and remove the site, and it is easy to cause damage to the trolley during the repeated use of the trolley, and the trolley needs to be continuously repaired, and Poor adaptability to section changes, which affects the normal cycle construction of tunnel excavation and support
Therefore, the construction method using a simple trolley has a large auxiliary workload, cumbersome operations, low construction efficiency, poor cross-section adaptability, and a long time occupation of the working surface, which has a great impact on the construction of other tunnel processes and the interference of mechanical equipment. Restricting rapid construction and high-level development of tunnels

Embodiment Construction
[0024] The technical solution of the present invention is further described below in conjunction with the accompanying drawings, but the scope of protection is not limited to the description.
[0025] A vehicle-mounted hydraulic trolley is adopted, and by using the power system of a bicycle, the trolley can travel freely until the excavation and support working face is in place, stabilized and withdrawn; The platform, the main platform 3 and the cantilever platform 4 can be freely lifted and extended to both sides by using the hydraulic system, so that the platform can be adjusted according to the size of the tunnel section, and can be freely adjusted to a suitable position on the excavation and support work surface, so as to carry out excavation. Excavation support construction.
[0026] The power system is a self-propelled drive system of the bicycle, which realizes the automatic walking of the trolley. Tunnels with small sections or flat construction sites use tire vehicle...

The invention discloses a vehicle-mounted hydraulic trolley for tunnel excavation and support, which comprises a main frame (3), and is characterized in that: the main frame (3) has at least two layers, and the bottom main frame (3) Installed on the trailer of the vehicle through the lifting hydraulic cylinder (5), the upper main platform (3) is stacked through the hydraulic telescopic rod (7), and the two sides of the main platform (3) are installed with cantilevered platforms (4) , the cantilever stand (4) is controlled to expand and contract in the horizontal direction through the telescopic hydraulic cylinder (6). Utilizing the power system of the bicycle, the trolley can travel freely until the excavation and support working face is in place, stabilized, extend the platform, and withdraw from the field; The platform can be adjusted freely by using the hydraulic system, and stretched to both sides, so that the platform can be adjusted according to the size of the tunnel section, and freely adjusted to the appropriate position of the excavation and support working surface, so as to carry out the tunnel excavation and support construction.
Description
technical field [0001] The invention relates to the technical field of tunnel construction equipment, in particular to a vehicle-mounted hydraulic trolley used for tunnel excavation and support. Background technique [0002] At present, in the tunnels constructed by drilling and blasting method, simple trolleys are generally used as the operation platform for excavation and support. The simple trolleys are mainly made of materials such as section steel, steel pipes, and steel mesh according to the size of the tunnel excavation section, and need to use a loader. Wait for the machinery to cooperate with the drive to drive to the tunnel excavation support working face. With the continuous deepening of tunnel excavation, it takes a lot of time to drive the trolley into place and remove the site, and it is easy to cause damage to the trolley during the repeated use of the trolley, and the trolley needs to be continuously repaired, and Poor adaptability to section changes affects...
