9results about How to "Avoid friction loss" patented technology

This invention relates to a handling robot, and more particularly to a handling robot with autonomous center of gravity adjustment capability. It includes a robot body, a steering component rotatably connected to the robot body, an electric slide rail fixedly connected to the steering component, a clamping component connected to the slider of the electric slide rail, and two opposing fixed plates fixedly connected to the robot body. This invention uses a pressure sensor to monitor the load in real time and drives a linear motor to move the battery compartment horizontally, achieving dynamic autonomous adjustment of the center of gravity. This effectively counteracts the overturning torque caused by heavy loads or high lifting, improving operational safety and stability. Simultaneously, it innovatively introduces a mechanical linkage mechanism that combines a Z-shaped guide groove with a lifting frame, allowing the rollers to be suspended in the air under normal conditions and automatically lowered as the battery compartment moves. This, combined with the energy absorption of a first spring, avoids unnecessary frictional wear while also providing shock absorption and protection.

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 application discloses a mine self-balancing anti-falling material elevator, and relates to the technical field of mine elevators, which comprises an elevator frame and an elevator box. Two traction machines are fixedly connected to the upper end of the elevator frame. First traction wheels are arranged on the two traction machines. A plurality of traction ropes are wound around the two first traction wheels. The lower ends of the plurality of traction ropes are fixedly connected to the upper end of the elevator box. A balancing mechanism is arranged on the elevator frame. The balancing mechanism comprises a U-shaped plate fixedly connected to the inner top of the elevator frame. Second traction wheels are symmetrically arranged on the lower end of the U-shaped plate through supports. Two U-shaped rods are slidably connected to the side walls of the U-shaped plate. The application can dynamically monitor and self-adaptively adjust the stress state of the traction ropes on both sides of the elevator box, automatically compensate the tension difference of the traction ropes on both sides, quickly correct the inclined posture of the elevator box, and ensure the uniform distribution of the loads of the traction ropes corresponding to the two traction machines.

The utility model discloses a middle pier flat rotation driving device, including the bearing frame, the inside of bearing frame is installed with lubricating oil storage jar and PLC controller in proper order, and the top of lubricating oil storage jar is installed with oil pump. The utility model runs, and the PLC controller controls the oil pump to start, can import lubricating oil to the middle oil distribution main pipe inside of the driven gear rotation through the effect of swivel joint, then, lubricating oil will flow to the outer edge of driven gear through four first oil distribution branch pipes, this can realize the lubrication protection between driven gear and driving gear, and lubricating oil will flow to the inside of corresponding annular limit sliding cavity at the edge of the rotation body for middle pier through four second oil distribution branch pipes, realizes the lubrication protection between annular limit sliding cavity and limit sliding block, and then through the comprehensive initiative lubrication of the moving friction part on the device, the fluency of device rotation drive is improved, also avoids the friction loss, prolongs the service life of device.

The utility model discloses a kind of equipment for diaminoanthraquinone cleaning, including reaction kettle, the feeding pipe is fixedly arranged on the upper end side of reaction kettle, the stirring mechanism for stirring is arranged in the middle part of the inside of reaction kettle and carries out reaction, the stirring mechanism includes transmission rod, speed reducer, motor, fixed link, movable link, scraper, the transmission rod is movably arranged in the middle part of the inside of reaction kettle by bearing, the speed reducer is fixedly arranged in the middle part of the upper end of reaction kettle, the power output shaft end between the speed reducer is fixedly connected with transmission rod, the motor is fixedly arranged on the upper end of reaction kettle on the side of speed reducer. The utility model is improved in view of diaminoanthraquinone reaction kettle, can be conveniently cleaned according to need, and when cleaning, it can be cleaned using scraper, and when not cleaning, scraper can be away from the inside side wall of reaction kettle, so unnecessary friction loss can be eliminated, to improve the use effect of device.

The utility model discloses putty powder mixing equipment, including the shell, the upper portion welding of shell has the installation cover, water tank and filter box, the upper portion of shell and installation cover are penetrated with the shaft pipe through bearing, the inside of shell is equipped with the storage tray through bearing, the inside fixed insertion of storage tray is inserted to the lower extreme of shaft pipe, the lower portion of storage tray is equipped with the mounting shaft, the lower portion fixed penetration of shell has the hopper. Advantageous effects: the utility model is provided with installation cover, shaft pipe and storage tray, through the combination of shaft pipe, storage tray and pressure spray head, utilize the double mode of liquid mixing and high pressure air purging, realize the clearance of mixed space inner wall putty powder, compared with traditional brush plate contact type scraping, this kind of non - contact cleaning mode avoids the friction loss of scraper and inner wall, not only prolongs the service life of equipment key components, also reduces maintenance cost and downtime, guarantees the continuity and stability of putty powder mixing operation.

The application discloses a kind of intelligent self-compensation sealed piston type pneumatic actuator, it is related to pneumatic piston technical field, including sliding piston, air passage and sealing ring, the air inlet of sliding piston top is connected with air outlet by air passage, the air outlet is used to guide high-pressure gas in the containing groove of sealing ring inside, the annular spring in the sealing ring is attached with the sealing groove of sliding piston, the sealing ring is connected with sliding piston by first side ring and second side ring.The application is equipped with sliding piston, air passage, sealing ring, annular spring, sealing cover, solenoid valve, first pressure sensor and second pressure sensor, realizes the intelligent automatic compensation adjustment and accurate control of sealing pressure, avoids excessive wear or damage of sealing ring due to excessive pressure, also prevents gas leakage due to insufficient pressure, improves sealing reliability, prolongs the service life of sealing ring.
