Abstract

The invention discloses a fully-mechanized excavation supporting device with emulsion capable of being automatically proportioned. Thus, the problems in the prior art, that excavation and supporting operation of fully-mechanized excavation faces cannot be synchronously and continuously performed, and the concentration of emulsion is not easy to control, can be solved. The device includes an emulsion automatic proportioning device and multiple supporting top beams; an oil cylinder is sleeved at the internal of each supporting top beam, and the adjacent ends of the oil cylinders are in fixationwith the supporting top beams; telescoping beams are fixed on the other ends of the oil cylinders; hydraulic props are vertically fixed on one sides of the telescoping beams; the upper end faces of the supporting top beams are provided with grooves; the grooves and the corresponding lower end faces of the supporting top beams are connected to sliding bodies through iron chains; and the sliding bodies on the lower end faces of the supporting top beams are provided with I-steel. The device is reasonable in design and compact in structure, and can maintain the original stress of roadways and theunchanged of rock stratum after excavation in a short time, so that conditions can be provided for subsequent and permanent supporting, and high supporting efficiency can be achieved; and automatic control operation can be realized, and labor intensity can be mitigated.

Description

technical field [0001] The invention belongs to the technical field of mine engineering equipment, and in particular relates to a fully-mechanized excavation support device capable of realizing synchronous and continuous operation of excavation and support in a fully-mechanized excavation working face, and capable of automatically proportioning emulsion. Background technique [0002] In the underground mining process of coal mines, the tunneling operation is the prerequisite for all other operations. With the increasing popularity of fully-mechanized excavators, the single-entry level of the fully-mechanized excavation face has greatly improved compared with the traditional "gun excavation" operation method. improvement. With the heavy-duty of underground mining equipment in coal mines and the upgrading of coal mining face equipment, many mines have realized the mining mode of "one well and one side", and the mining efficiency has been greatly improved. However, the efficie...
