Abstract
The invention discloses a self-laying device for a construction trench cover plate in a tunnel, which is technically characterized by consisting of a four-leg frame, a guide system arranged on a front upright post of the frame, a driving system of a rear upright post, a hoisting system arranged below an upper cross beam and a control system. The defects that the cover plate is inconvenient to use due to the narrow space of large equipment and cannot be laid manually due to the overweight of the cover plate in the existing tunnel are overcome. 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
Technical Field
The invention relates to a construction device for laying a channel cover plate in a tunnel, in particular to a self-propelled laying device for the channel cover plate in the tunnel, and belongs to the field of road and bridge engineering.
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.
Disclosure of Invention
The invention aims to overcome the defects of the existing device for laying a cover plate in a tunnel, and discloses a device for automatically laying a construction trench cover plate in the tunnel.
The technical scheme of the invention is composed of a frame, a guide system arranged on a front upright post of the frame, a driving system of a rear upright post, a hoisting system under an upper cross beam and a control system.
The invention overcomes the defects that large equipment is inconvenient to use due to narrow space, the cover plate cannot be laid manually due to heavy weight and the like in the conventional tunnel inner cover plate laying. 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.

The reference numbers are as follows: the device comprises a rack 1, a connecting plate 2, a driving wheel 3, a driving motor 4, a transmission chain 5, a guide shaft 6, a guide wheel 7, a guide rod 8, a guide handle 9, a linkage rod 10, a swinging rod 11, a slide rail 12, a sliding wheel 13, a movable support 14, a hoisting motor 15, a steel wire winch 16, a pulley 17, a steel wire rope 18, a lifting hook 19 and a control box 20.
Detailed Description
The invention is described in further detail below with reference to examples and figures:
the machine frame 1 consists of four upright posts and cross beams, a guide system is characterized in that the lower ends of the front two upright posts of the machine frame 1 are respectively sleeved with a guide shaft 6 through a connecting plate 2, a guide wheel 7 is hinged below the guide shaft 6, the middle part of the machine frame 1 is respectively hinged with a guide rod 8, the upper end of the guide rod 8 is connected with a swinging rod 11, the lower end of the guide rod 8 is fixed with the guide shaft 6, the two swinging rods 11 are connected through a linkage rod 10, one guide rod 8 is fixed with a guide handle 9, the lower ends of the rear two upright posts of the machine frame 1 are respectively hinged with a driving wheel 3 and fixed with a driving motor 4 through the connecting plate 2, the driving motor 4 is connected with the driving wheel 3 through a transmission chain 5, a hoisting system is characterized in that a fixed slideway 12 is penetrated under the two cross beams at the upper part of the machine frame 1, a sliding wheel 13 is sleeved in the slideway 12, the, the hoisting motor 15 is connected with a wire winch 16, one end of a wire rope 18 is wound on the wire winch 16, the other end of the wire rope passes through a pulley 17 to be connected with a lifting hook 19, and a control box 20 is fixed on one side of the frame 1.
When the lifting system is in work, firstly, a power supply of the control box is switched on, a lifting system switch is turned on, so that the lifting hook descends to hang the cover plate and ascends to a certain height, the support is slidably moved to a set position, then the guide system and the driving system are started, the driving direction is adjusted by swinging the guide handle, and when the lifting system is driven to a position where the cover plate needs to be installed, the lifting system switch is operated to descend the cover plate to the installation position.
