Problems solved by technology
Foreign anchor trolley equipment has entered the Chinese market, but the price is expensive, and the on-site supporting process requirements are strict. According to the investigation, there are few practical applications in tunnel construction sites
Many domestic engineering equipment companies are optimistic about the market prospect of bolting trolleys, but the prototype single-arm bolting trolleys are mainly used, and the construction effect of the prototype is not obvious on the construction site and is not accepted by users

specific Embodiment
[0040] Specific embodiment: transport the bolt to the construction tunnel, drive the equipment into the construction tunnel to be constructed, connect the power line of the electric control system 7 to the power supply, power on the equipment, install the grouting system 6, the water and air system 10 and the hydraulic system 11 preparations are ready, the staff controls the left automatic anchor arm 14 and the right automatic anchor arm 13 to the appropriate position for drilling operations through independent dual wireless remote controllers, and starts the water and air system 5 to work at the same time. The rock drilling propulsion beam on the automatic bolt arm 14 and the right automatic bolt arm 13 drills the bolt hole. After the bolt hole is drilled, the staff controls the left automatic bolt arm 14 and the right automatic bolt arm through independent dual wireless remote controllers. The rock drilling propulsion beam on the lever arm 13 exits and rotates the rock drilli...

The invention discloses a device and construction method for anchor rod supporting constriction of a highway tunnel and a railway tunnel, and provides an integrated construction device and construction method. The device comprises a rack assembly, an automatic anchor rod arm, a working platform arm, an anchor rod arm support, a cab ceiling, a cab assembly, a moisture system, a grouting system, anelectric control system, a traveling system, a power system, a hydraulic system and dual independent wireless remote controllers; and the device integrates anchor rod hole drilling through the two arms, anchor rod mounting through the two arms and grouting through the two arms. The device and the construction method have the beneficial effects that the structure is compact, the construction difficulty is lowered, the construction cost is lowered, the construction efficiency is improved, the anchor rod mounting precision is high, and a worker is prevented from mounting anchor rods at a high altitude; and the site entering and exiting time of an anchor rod trolley drill and a grouting trolley grouting replacement device is reduced, and the operation time (of an existing single-arm anchor rodtrolley) is reduced.
Description
technical field [0001] The invention relates to the field of mechanical equipment for construction of road tunnels and railway tunnels, in particular to equipment and construction methods for bolt support construction of road tunnels and railway tunnels. Background technique [0002] According to the "Several Opinions on Further Strengthening the Quality and Safety Supervision of Tunnel Projects" (Jiaozhijianfa [2013] No. 549) issued by the Ministry of Transport of my country in September 2013, it is clearly pointed out that new mechanical equipment for tunnel construction should be widely used, especially In terms of tunnel construction technology, it is not only an effective guarantee of construction safety and quality, but also a fundamental measure to implement the concept of people-oriented. At the same time, with the continuous improvement of national requirements for project quality, operation safety, occupational health, etc., the use of mechanical construction methods...
