The utility model discloses a convenient bed guardrail, through being formed with independent guardrail opening between two vertical columns of each guardrail main part, equivalent to setting the passable passageway on the left, right, front (or rear) three sides of bed body, and user can choose the guardrail opening direction freely according to the actual scene, and thoroughly get rid of the path limitation of "single -sided opening", simultaneously, three -sided guardrail frame covers the main activity area (such as left and right sides prevent rolling, front end prevent turning over and falling) of bed body, and the protection range is more comprehensive, to satisfy the double demand of user to security and use convenience.

The present disclosure relates to a scraper machine for rock wool collection, belonging to the technical field of industrial material conveying equipment, comprising a rack and a transmission mechanism arranged on the rack, the transmission mechanism comprising a driving sprocket arranged at the tail of the rack and a driven sprocket arranged at the head of the rack, the driving sprocket and the driven sprocket being provided with a transmission chain, and the middle part of the rack being provided with a bottom plate arranged horizontally with the rack, and a certain gap being maintained between the bottom plate and the transmission chain; the axial baffle arranged on the transmission chain enables the chain to only bend along the rotation of the sprocket, avoiding the central droop caused by the self-weight of the chain, and the sagging gravity is converted into the tension of the upper chain, so that the chain remains straight, thereby ensuring the constant gap between the scraper rod and the bottom plate and avoiding friction loss; the driving sprocket and the driven sprocket are arranged in a lower position, cooperating with the adjustable tensioning sleeve structure, and eliminating the energy loss caused by the friction of the traditional drag chain plate.

The utility model relates to an ultra-deep hole time-sharing driving, self-adaptive floating sealing and lifting self-locking large-torque drilling machine, and belongs to the technical field of coal mine drilling machines. Comprising a rack, a sliding frame is arranged on the rack, an angle adjusting unit is arranged between the rack and the sliding frame, and a power output unit is arranged on the sliding frame; the power output unit comprises an output shaft and a power shell, and the output shaft penetrates through the power shell; an oil inlet sleeve assembly is arranged in an inner cavity of the power shell; the oil inlet sleeve assembly comprises an oil inlet sleeve, and the oil inlet sleeve is arranged on the output shaft through a rolling bearing; an oil inlet core is inserted into the oil inlet sleeve, and an outlet of the oil inlet core is communicated with the oil inlet cavity of the output shaft; two sealing grooves are symmetrically formed in the inner wall of the oil inlet sleeve, and sealing rings are clamped in the sealing grooves respectively. The oil inlet sleeve is arranged on the output shaft through the rolling bearing, and the sealing ring is mounted between the oil inlet sleeve and the output shaft, so that hydraulic oil leakage is avoided; the drilling rig carriage fixing reliability is improved, and the drilling rig carriage orientation angle is guaranteed.

The application discloses a kind of high-flexibility torsion-resistant composite shielding cable for humanoid robot joint and preparation method, it is related to humanoid robot special cable technical field, cable is sequentially arranged from inside to outside flexible conductor bundle, fluoroplastic thin-wall modified insulation layer, carbon fiber filling flexible anti-torsion buffer layer, elastic wave-shaped adaptive composite shielding layer, flexible tensile buffer layer and glass fiber reinforced polyurethane outer sheath.The application uses double-layer homodromous twisting ultrafine tin-plated copper conductor to improve flexibility, and relies on circumferential array carbon fiber strip to build elastic anti-torsion system;Through the concave-convex base of elastic rope strip prefabrication, make aluminum foil and copper wire braided shielding form synchronous wave-shaped deformable structure, solve the problem of traditional shielding layer torsion fracture, efficiency attenuation.Collaborate modified ETFE thin-wall insulation and wear-resistant weather-resistant modified polyurethane sheath, give consideration to insulation, tensile, anti-fatigue performance.
