Automatic control architecture mobile trestle

Abstract

The invention discloses an automatic control architecture mobile trestle. In order to overcome such defects as low span, difficult displacement and low efficiency in traditional tunnel construction, a movable support frame is arranged between two rows of main bridges, and is provided with frame support legs; wheel rails are respectively arranged at the upper parts and the lower parts of opposite inner side surfaces of the two rows of main bridges; movable rollers are respectively arranged at the upper parts and the lower parts of two side surfaces of the movable support frame, and are movably connected with the wheel rails; a driving wheel is arranged between the two rows of main bridges; and transverse moving mechanisms are arranged on the main bridges near the end parts. The automatic control architecture mobile trestle is used for tunnel construction, can realize high-span line production, continuous construction, automatic architecture displacement, automatic gesture control, easy mounting displacement, flexible movement, fast construction, high efficiency, compact structure, less occupied space and low production and use costs, and in particular, is suitable for narrow-space single line rail tunnel construction under complicated geological conditions.

Description

Technical field [0001] The invention relates to a trestle bridge mainly used for tunnel construction, in particular to a mobile trestle bridge with an automatic control structure. Background technique [0002] Tunnel construction is limited by the narrow space, the construction equipment is difficult to install, and the operation links are complicated, the safety hazards are many, and the efficiency is difficult to improve, especially in single-track tunnels. [0003] At present, the construction level of the tunnel is getting higher and higher. In order to ensure the integrity of the tunnel invert construction and increase the bearing capacity, it requires streamlined operation and continuous construction. The one-time construction length of the invert should reach more than 24 meters. [0004] Existing tunnel construction requires not only large-span displacement and continuous large-span flow operation, but also the excavation of the bottom of the inverted arch. [0005] Therefore,...

Problems solved by technology

[0006] The disadvantages of existing trestle bridges are: small span (usually construction length 6-12 meters), short construction length, difficult displacement, unable to realize 24-meter long-span flow operation and continuous construction

[0007] Secondly, the existing structure of trusses on both sides and the middle channel can increase the span of the main bridge and make the construction length reach 16 meters. It is narrow and difficult to construct. It is only suitable for double-track tunnels and cannot adapt to the increasing number of single-track tunnels under complex geological conditions.

[0008] In addition, in order to take into account the excavation and slag construction at the bottom of the inverted arch, the existing trestle bridge needs to add trestle pedals to increase the total length of the trestle bridge by at least a dozen meters. When cleaning the bottom slag, it is necessary to retreat to the filled surface of the inverted arch. On the one hand, it is very troublesome to fall back, on the other hand, the follow-up construction is not allowed to be too far apart, which will cause mutual interference

There is no good solution, which greatly affects the application of the trestle
