Railway vehicle body chassis structure

ActiveCN103832446ASimple structureSolve the maintenance space problemUnderframesBogieControl theory
The invention discloses a railway vehicle body chassis structure. The railway vehicle body chassis structure soles the problems that the giant torque force is caused due to the fact that a front-arrangement type vehicle hook mounting hole is formed in the side face of a vertical plate of a traction beam, and no operation space exists for mounting a steering frame traction base. The railway vehicle body chassis structure comprises two chassis edge beams, a chassis end beam and a sleeper beam arranged between the two chassis edge beams, a traction beam, a vehicle hook mounting sectional material and a traction guide beam are arranged between the sleeper beam and the chassis end beam, the traction beam is fixed between the sleeper beam and the vehicle hook mounting sectional material, and the traction guide beam is fixed between the vehicle hook mounting sectional material and the chassis end beam. Traction wing plates are fixedly arranged on the two sides of the vehicle hook mounting sectional material, the traction wing plates are fixedly connected with the chassis edge beams on the corresponding sides, and a jumper box is arranged between the traction wing plates and the traction guide beam. The problems are completely solved by optimizing the structures of vehicle hook mounting sectional material, the traction beam and other components, and the high-intensity performance that a vehicle body can bear 1000 kN of compression loads is kept.

Surgical auxiliary support frame for ophthalmologists

The invention belongs to the technical field of surgical auxiliary tools, and particularly discloses a surgical auxiliary support frame for ophthalmologists. By the aid of the surgical auxiliary support frame, the problem of easiness in shaking due to the sense of fear of patients in eye surgery can be solved. The scheme includes that the surgical auxiliary support frame comprises a bottom plate;a headrest is connected with the center of the top of the bottom plate by bolts, side plates are vertically arranged at two ends of the bottom plate, fixing plates are welded at two ends of the bottoms of certain sides of the two side plates, the certain sides of the two side plates are far away from each other, and electric push rods which are horizontally arranged are connected with the centersof the tops of the two side plates by bolts. The surgical auxiliary support frame has the advantages that the heads of patients can be fixedly clamped by the two electric push rods by the aid of memory sponge mats and can be prevented from shaking in surgery procedures; music can be played by a music player in the surgery procedures, accordingly, nervous mental states of the patients can be eased,and the surgical auxiliary support frame is beneficial to smoothly carrying out surgery on the patients; the eyes of the patients can be illuminated by supplement light by the aid of illumination lamps, accordingly, the surgery can be conveniently smoothly carried out by the ophthalmologists, and eye surgery risks of the ophthalmologists can be reduced.

SDOF parallel automatic offset adjusting system and method for optical lens

The invention provides an SDOF (Six Degrees of Freedom) parallel automatic offset adjusting system and method for an optical lens and belongs to the technical field of precision automatic assembly ofoptical lens. Automatic offset adjustment is realized based on a measurement result of decentration and an SDOF parallel structure. The system is mainly composed of a lens barrier adjusting module, adecentration measuring module and an automatic offset adjusting module. The automatic offset adjustment method includes calculating two centers of sphere of a to-be-assembled lens based on the decentration measurement data and driving the SDOF parallel structure for offset adjustment. A method of alternative conduction of measurement and adjustment is employed; namely, whether an offset adjustmentresult meets requirements or not is verified through re-measuring the decentration after each process of offset adjustment. If the offset adjustment result does not meet the requirements, offset adjustment is performed again through refitting of optical axis until the precision meets requirements. According to the invention, integration of decentration measurement and lens automatic adjustment isachieved and measurement of lens decentration and offset adjustment can be realized quickly. Lens offset adjusting precision can be ensured to meet requirements and lens assembly efficiency is improved greatly.
