The invention relates to a search and rescue robot used in pit, belonging to the robot technology field. The search and rescue robot comprises an explosion-resistant enclosure, two sets of symmetrical running system, independent swinging arm systems and a controlling system; transmission mechanisms of the controlling system, the running systems and the swinging arm systems are arranged in the explosion-resistant enclosure, the controlling system is connected with a driving mechanism, a mechanical cradle head and an optical fiber laying device are arranged above the explosion-resistant enclosure, the optical fiber of the optical fiber laying device is electrically connected with the controlling system, a sensor group is internally arranged in the mechanical cradle head, and the sensor group and a cradle head drive plate are electrically connected with the controlling system. A static positive pressure explosion-resistant enclosure is adopted in the invention, when the static positive pressure is reached, the moving ability of the robot is improved. A four-swinging-arm independent driving mechanism is adopted, the posture of the robot is accurately controlled, and the adaptbility and the barrier jumping ability of the robot to a complex terrain are increased. The method of vehicle-mounted optical fiber is adopted, the optical fiber is laid freely during movement, and the effect to the moving ability of the robot, which is caused by the friction of the optical fiber and the clamping of the optical fiber, is reduced.

Preparation method of hollow fabric with radial elastic shrinkage

The invention discloses a preparation method of a hollow fabric with radial elastic shrinkage and relates to the preparation method of the hollow fabric. The object of the invention is to solve the problem that elastic hollow fabric available in the market does not meet the requirement of thin diameter and longitudinal elasticity and very large radial elasticity when being used in a specific task, has poor strength of bearing accidental drawing and poor wearability, as well as poor dimensional stability, and especially poor radial elasticity. The method comprises the preparation work of warp yarns, which includes selecting fine denier 75-200D aramid fiber fibers, 100-300D PBO (p-phenylene-2,6- benzobisoxazazole fiber) fibers or aramid fibers and PBO combined filament yarns as warp yarns; preparation work of weft yarns; directly winding of the weft yarns to form a pirn with a size same as that of a shuttle of a shuttle loom; and a determining and weaving process of metric portie. The hollow fabric prepared by the preparation method provided by the invention has excellent radial elastic recovery, and also the characteristics of superstrong resistance to longitudinal stretching force and wear resistance and corrosion resistance. The method is used for preparing elastic hollow fabrics.

Loose core sheet riveting device

The invention discloses a loose core sheet riveting device. The loose core sheet riveting device comprises a supporting assembly, a riveting assembly and a riveting driving assembly; the supporting assembly is provided with a sheet positioning site for positioning the loose core sheet; the sheet positioning site is provided with a reference direction; the reference direction is the axial directionof a to-be-riveted opening of the loose core sheet after the loose core sheet is positioned on the sheet positioning site; the riveting assembly is provided with a riveting block which is driven by the riveting driving assembly to move back and forth relative to the sheet positioning site and along the reference direction; and the riveting part of the riveting block is a trapezoidal riveting groove with a wide opening and a narrow bottom. In the riveting process, the two riveting parts are close to each other and can adaptively adjust to maintain the own shape, so that the extruded deformation can be avoided when the riveting parts are close to each other to be riveted; a hole formed after riveting adopts a round structure, the product has good appearance, the activity freedom degree of the loose core sheet and a Japanese circle is good, and the user experience feeling is excellent. The loose core sheets with any different sizes can be riveted through adjustment; and the product can automatically separate from the riveting device after product riveting and assembling are completed, so the loose core sheet riveting device is very flexible, simple, convenient and efficient.
