Abstract: The present invention relates to the technical field of engineering technology equipment and methods, in particular to a telescopic multifunctional working vehicle capable of operating in both directions and evacuating transversely, and an application method thereof. The telescopic multifunctional working vehicle comprises a fixing and lifting mechanism and a transverse moving and lifting mechanism. The working vehicle is composed of a front vehicle body and a rear vehicle body, wherein the front vehicle body is connected with the rear vehicle body through a telescopic mechanism used for realizing the contraction and the expansion between the front vehicle body and the rear vehicle body. The working vehicle is further provided with a hanging system used for hanging and moving working devices. A rail clamping device is arranged at the bottom of the working vehicle.

Abstract: It relates to the engineering technology science, in particular to a novel track layer for urban rail traffic engineering and its construction method. The novel track layer comprises lifting and walking trolleys, a connecting truss beam, a track running mechanism and a supporting structure. Horizontal extending and vertical supporting structures of each lifting and walking trolley are operated firstly so as to lift the whole novel track layer to a height at which a track material is hoisted and unloaded. A hoisting car is used to lift up the track material to leave from a flat trunk and a material supporting cushion. The novel track layer continues to walk forward to a designed mounting position of a track section, and then the track material is unloaded. Steel tracks are connected and a temporary track section support is mounted to fix a newly mounted track section.

Abstract: A method for producing laccase by liquid fermentation of Lentinus edodes comprises the following steps of: (1) inoculating strains of Lentinus edodes into the PD liquid fermentation medium to perform activation culture and obtain a seed liquid; (2) inoculating the seed solution into a liquid fermentation medium to perform liquid fermentation culture, then adding an expansin solution to perform further culture, separating the supernatant to obtain a ferment solution; (3) extracting laccase from the ferment solution. A plant expansin and an optimized fermentation method are applied for producing laccase by liquid fermentation of Lentinus edodes, which increases the liquid fermentation output of laccase of Lentinus edodes remarkably, by more than 3 times in comparing with traditional fermentation production methods.
