Abstract

The utility model discloses a construction slot apron is laying device by oneself in tunnel, its technical characteristic is by four legs frames, set up lifting system and control system under the actuating system of the guide system of frame front column, rear column, upper portion crossbeam and constitute, overcome in the present tunnel apron lay because of the inconvenient use of the narrow and small main equipment in space and because of apron overweight manual work defect such as can't lay. The device not only ensures the engineering quality, improves the cover plate laying accuracy, but also reduces the construction cost, reduces the air pollution in the tunnel, saves energy, protects environment, has simple structure, convenient operation and safe and reliable use, and is an ideal self-laying device for the construction groove cover plate in the tunnel.

Description

Self-laying device for construction groove cover plate in tunnel

Technical Field

The utility model relates to a construction equipment is laid to trench cover board in tunnel specifically is a construction trench cover board is laying device by oneself in tunnel, belongs to road bridge engineering field.

Background

Along with the rapid development of the construction of high-speed railways and highways, the number of the construction groove cover plates in the tunnels is increased, the construction groove cover plates can be divided into cable trough laying cover plates and ditch laying cover plates according to categories, and the construction groove cover plates are used for laying the cable troughs in the tunnels and laying the ditches in the tunnels. At present, two methods are mainly adopted for laying the cover plate in the tunnel: one method is to carry and lay the cover plate by manpower, the original laying mode not only needs a lot of manpower, but also has low working efficiency and potential safety hazard, and as the quality requirement of road and bridge construction and the production safety level are continuously improved, the quality requirement of the cover plate of the tunnel cover plate is also continuously improved, the weight of the cover plate is heavier and heavier, so the manual laying can not be finished; the second method is to use large-scale equipment to lay the cover plate, but because the construction site in the tunnel is narrow and small, the construction is very difficult by using the large-scale equipment, the cover plate edges and corners are easy to collide and damage, and meanwhile, the cover plate cannot be accurately laid to a set position. At present, no self-laying device for the cover plate in the tunnel, which can reduce the labor intensity of constructors, improve the construction efficiency and ensure the laying quality and accuracy of the cover plate, is available.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the defect that the apron device exists of laying in the present tunnel, and disclose a construction slot cover board is laying device by oneself in tunnel.

The technical scheme of the utility model by the frame, set up lifting by crane system and control system under the actuating system, the upper portion crossbeam of frame front column and constitute.

The utility model overcomes apron is laid in present tunnel because of the inconvenient use of the narrow and small main equipment in space and because of apron weight overweight manual work can't lay the defect such as. The device ensures the engineering quality, improves the cover plate laying accuracy, reduces the construction cost, reduces the air pollution in the tunnel, saves energy, protects environment, and has simple structure, convenient operation and safe and reliable use.
