5results about How to "Reduce moving friction" patented technology

The application provides a fan blade defect detection device, and relates to the technical field of fault diagnosis devices.The device comprises a vehicle body, a threaded knob provided with a connecting point for connecting a rope at the axis thereof on one side of the vehicle body, a long rope fixedly connected to one end of the threaded knob, and balls uniformly provided on the long rope and in rolling contact with the fan blade.The application sets an L-shaped plate linkage rope pressing and detection roller mechanism to synchronously narrow the long rope annular area when driving the detection roller to press the blade, thereby forcing the vehicle body and the detection roller to actively enhance the dynamic fitting with the curved surface.Combining the long rope with balls to reduce the moving friction, the vertical winding roller maintains the trajectory accuracy, and the inclined detection roller expands the contact area to adapt to the curved surface.In addition, the visual monitoring is used to realize the stable contact scanning and optical review collaborative detection of the complex curved surface defects.

The utility model relates to a quick disassembling and assembling tool for a tuyere water jacket of a spray gun of a metallurgical furnace, which belongs to the technical field of disassembling and assembling tools for tuyere water jackets of metallurgical furnaces and comprises a chuck, a hand lever and a fixing part, a lever hole is arranged in the middle of the chuck, and a plurality of fixing holes are arranged on the periphery corresponding to the lever hole; one end of the hand rod is detachably inserted into the rod hole; the multiple fixing pieces are fixed in the multiple fixing holes correspondingly, and the multiple fixing pieces are detachably connected to the spray gun tuyere water jacket so that the spray gun tuyere water jacket can be moved to a safety area while the hand rod is pulled. The structure of a traditional metallurgical furnace spray gun tuyere water jacket disassembling tool is improved, the multiple fixing pieces fixed to the chuck are detachably connected to the spray gun tuyere water jacket, then the position of the spray gun tuyere water jacket is moved through the hand lever, and the spray gun tuyere water jacket can be rapidly positioned and connected in a narrow space; and the dismounting moving speed of the spray gun tuyere water jacket is increased.

The application discloses a wind power tower cylinder welding error edge amount correction mechanism and relates to the technical field of wind power single pile thick plate processing. The mechanism comprises a correction platform and a connecting plate. A servo motor is arranged on the front side of the correction platform, and a lead screw is arranged on the output end of the servo motor. The mechanism is positioned by a limiting assembly one, a limiting assembly two and an adjusting assembly. The arc-shaped fixing plate body is attached to the surface of the tower cylinder and the single pile thick plate to realize stable clamping. The hydraulic rod one and the hydraulic rod two are used for accurate driving position adjustment. The servo motor and the lead screw are used for uniform speed transmission. The axial movement and the longitudinal error edge correction of the tower cylinder and the single pile thick plate can be accurately controlled. The error edge amount meets the welding standard. Meanwhile, the rollers of the auxiliary assembly reduce the moving friction, the scrapers clean the debris in real time, the components are prevented from being jammed, the correction stability and the accuracy are further improved, the safety hazards such as weld cracking and component deformation are reduced, and the service life of the wind power tower cylinder and the single pile is prolonged.

The utility model discloses a convenient installation and debugging auxiliary device of five -axis rotary work platform, specifically relates to five -axis rotary work platform installation field, including installation base, the bottom of installation base is provided with drive groove, fixedly installed with hydraulic cylinder in drive groove, the output shaft of hydraulic cylinder is fixedly connected with auxiliary mobile device, the bottom of installation base is fixedly installed with a plurality of adjusting devices symmetrically. The utility model is simple to operate when using, utilizes hydraulic cylinder drive mounting panel and support ball, greatly reduces device moving friction, overcomes the moving problem of five -axis rotary work platform because of heavy weight, improves installation efficiency, reduces labour intensity, and the adjusting device of ball screw and bearing block constitutes can accurate control height adjustment, and the stable and reliable structure.

The utility model discloses an anti-jamming hard sealing plug valve conical surface structure which comprises a valve shell, a plug valve element is rotationally connected to the bottom of an inner cavity of the valve shell through a first rotating shaft, a valve element rod is arranged on the upper side of the plug valve element, and the anti-jamming hard sealing plug valve conical surface structure further comprises a self-lubricating mechanism. The self-lubricating mechanism comprises oil storage cavities, a partition plate, first through holes, second through holes and an opening and closing assembly, the oil storage cavities are formed in the front end and the rear end of the wall body of the valve shell correspondingly, and the second through holes which are evenly distributed are formed in the wall bodies, close to the center of the valve shell, of the oil storage cavities. According to the anti-jamming hard sealing plug valve conical surface structure, impurity filtering can be conducted on liquid flowing through the hard sealing plug valve conical surface through the filtering element, the probability of the plug valve opening and closing jamming phenomenon is reduced, meanwhile, the device conducts automatic lubricating operation on the hard sealing plug valve conical surface, and the safety of the device is improved. The moving friction force of the part is reduced, abrasion is reduced, the sealing performance is improved, and the probability that the conical surface of the hard sealing plug valve is jammed is further reduced.
