The invention provides a high-performance PTFE (Polytetrafluoroethylene) needled felt filter material and a preparation process thereof. The filter material sequentially comprises a fine denier PTFE fiber mesh layer, a first base fabric layer, an upper PTFE fiber mesh layer, a second base fabric layer and a lower PTFE fiber mesh layer; the fine denier PTFE fiber mesh layer is made by pre-treating, pre-opening and carding a fine denier PTFE fiber, the first base fabric layer and the second base fabric layer are made by pre-treating PTFE base fabrics, and the upper PTFE fiber mesh layer and the lower PTFE fiber mesh layer are made by pre-treating, pre-opening and carding common PTFE fibers. The filter material provided by the invention is stable in structure, high in filter precision and strength, and good in heat resistance and corrosion resistance, and is used for filtering smoke and collecting products under various complex working conditions.

The invention relates to a fixed-shaft type hybrid power transmission for an integrated drive motor. The fixed-shaft type hybrid power transmission comprises input shafts in drive connection with an internal combustion engine, output shafts keeping rotary drive connection with wheels through a differential mechanism, a reverse gear shaft, the integrated motor, gear pairs and synchronizers, wherein a plurality of input shafts and output shafts are formed by idler gear-synchronizer-consolidation gear pairs, a mutual exclusive forward speed ratio is formed between the input shafts and the output shafts, the reverse gear shaft is formed by a plurality of reveres gears, the reverse speed ratio from input to output is formed by the reverse gear shaft and can be cut off, and the integrated motor is connected with the input shafts, the output shafts and the reverse gear shaft in a driving mode through the gear pairs and the synchronizers. Compared with the prior art, while the variable power transfer path of the motor is achieved, axial and radial arrangement space of the motor can be effectively increased, and the fixed-shaft type hybrid power transmission is suitable for being applied to strong-mixing and plug-in hybrid electric vehicles.

The invention discloses a positioning locking system for a crystallizer. The system includes a positioning plate disposed on the crystallizer, a vibration framework in a vibration device, and a positioning reference block disposed on the vibration framework, and further includes positioning devices, locking devices and a manipulation device, wherein the manipulation device is separately used for driving the positioning devices and the locking devices, and the positioning devices and the locking devices are all disposed on the vibration framework. The system can ensure reliable fixing of the crystallizer and the vibration framework in a vibration process of casting steel, and at the same time solve the problem of stability of a foot roller and the radian of a bending section.

The invention discloses a lower launching nose type fixed-point hoisting bridge girder erection machine through-tunnel method based on a front support leg, and relates to the technical field of bridgegirder erection machines. The method comprises the following steps: anchoring the lower end of the front support leg with the ground; changing span of the bridge girder erection machine; laying downa roller to make the roller completely contact with a launching nose track; turning over the lower section of the front support leg, and driving, by a rear support leg, the bridge girder erection machine go out of the tunnel; removing a lower cross beam and mounting an upper cross beam to original position; recovering support of the lower section of the front support leg, and enabling an oil cylinder at the upper end of the front support leg to work; jacking the front support leg up to a normal girder erection state. According to the method disclosed by the invention, system transformation isrealized through oil cylinder support and hinge pin connection; in combination with the longitudinal shift of an HILMAN roller, the girder erection position of the front support leg of the bridge girder erection machine is changed; the structural form is simple and the operation is convenient; by integrating the longitudinal shift walking drive of the launching nose and the longitudinal shift walking drive of the bridge girder erection machine, the structural form is simple; when passing through the tunnel, the transporting girder vehicle carries the launching nose and the bridge girder erection machine to pass through the tunnel at one time, thus the discharge workload is small, and the working condition adaptability is relatively good.
