Technical Field
The invention belongs to the technical field of TBM (full face tunnel boring machine), and particularly relates to a TBM main belt conveyor.
Background
The TBM main belt conveyor is residue soil transportation equipment which is arranged in a hollow TBM main beam and is mainly used for transporting residue soil from a cutter head to rear matched transportation equipment and then to the outside of a tunnel in the TBM tunneling process. When the TBM machine tunnels in a weak and broken stratum, the slag soil generation amount is large, and a large amount of slag soil falls on a tail end belt of the main belt conveyor, so that the main belt conveyor of the TBM machine is pressed by the slag soil and cannot work normally, and the normal work of other parts of the TBM machine is influenced. Therefore, when the main belt conveyor is pressed by the slag soil, the main belt conveyor needs to be quickly taken off so as not to influence the normal tunneling work.
At present, when a main belt conveyor is pressed by muck and cannot work, a TBM machine is required to stop tunneling, manual drilling is carried out inside a cutter head for cleaning, all the muck on the main belt conveyor is bagged by manual shovels and carried out, and the method for getting rid of the muck wastes time and labor and is low in efficiency.
Disclosure of Invention
In order to better solve the problem, the invention provides a TBM (tunnel boring machine) main belt conveyor.
In order to achieve the purpose of the invention, the technical scheme of the invention is as follows: the utility model provides a TBM host computer belt feeder, includes TBM quick-witted girder, belt feeder body frame, driving roll, driven cylinder, belt, connects sediment fill and host computer belt feeder control system, wherein: the belt feeder body frame is including fixed body frame and activity tailstock, fixed body frame is fixed with TBM quick-witted girder, but the activity tailstock and the rotatory articulated luffing motion together of fixed body frame, activity tailstock middle part is provided with lift cylinder, lift cylinder one end with TBM quick-witted girder fixed connection, the other end with the activity tailstock is connected, connect the top and the TBM girder fixed connection that the sediment fill is located the belt, host computer belt conveyer control system is equipped with the reverse rotation control system of belt.
The movable tail frame is hinged to the fixed main frame through hinge holes, and the hinge holes are formed in the lug plates.
And lifting oil cylinders are symmetrically arranged on two sides of the movable tailstock, the piston sections of the lifting oil cylinders are hinged with the movable tailstock, and the lifting oil cylinders are merged into the TBM hydraulic system through oil pipes.
The number of the lifting oil cylinders is 2, 4 or 6.
The length of the movable tailstock is 5-7 m.
The bottom of the slag receiving hopper is in lap joint with the belt.
The bottom of the slag receiving hopper is provided with a rubber belt with the width of 18-22cm, and one third part of the bottom of the rubber belt is lapped with a belt of a main machine belt conveyor.
Has the advantages that:
according to the invention, when the TBM main belt conveyor is pressed by muck and needs to be quickly removed from the ground, the lifting oil cylinder descends to enable the movable tailstock to descend and be separated from the muck receiving hopper, so that the front part of the main belt conveyor is declined at a certain angle to form an opening, when the TBM main belt conveyor is pressed to be dead, as the muck is at the end position, a part of muck directly falls into the cutter head along with the influence of gravity on the opening, at the moment, the belt of the main belt conveyor is reversed through the main belt conveyor control system, the accumulated muck can be completely poured into the cutter head, the muck cleaning time is greatly saved, the main belt conveyor is quickly removed from the ground, the manual slag cleaning time and workload are reduced, and the tunneling can be quickly recovered.
