According to the mechanical arm device with the return and reversal function,the structure of reversing, braking, clamping and returning is novel, the design is reasonable, and the work efficiency and the reliability are effectively improved.

The invention relates to a double-arm drying type hoisting permanent magnet. The double-arm drying type hoisting permanent magnet comprises a magnetic system and a driving system, wherein the driving system is arranged on the magnetic system; the magnetic system is positioned at the lower part of the driving system; and the driving system achieves the goal of sucking heavy objects and unloading the heavy objects through the rotation of a rotary composite permanent magnet in the magnetic system. The double-arm drying type hoisting permanent magnet is characterized in that the driving system comprises driven cylindrical gears, a driving cylindrical gear, a hanging ring, a front small hanging chain, front hoisting chains, a back small hanging chain, back hoisting chains and a shaft system; the two driven cylindrical gears are respectively connected onto the end parts of a rotating shaft, and are engaged with the driving cylindrical gear arranged in the middle; the driving cylindrical gear is connected with the end part of the shaft system; one ends of the two front hoisting chains and the two back hoisting chains are respectively connected with an upper cover through a hanging lug arranged on the upper cover, and the other ends are connected onto the hanging ring; one end of the front small hanging chain is connected with the end part of a front swinging rod arranged on the shaft system; one end of the back small hanging chain is connected with the end part of a back swinging rod arranged on the shaft system; and the other ends of the front and back small hanging chains are connected onto the hanging ring. The permanent magnet has the advantages that the structure is simple and reasonable; and the application range of the hoisting permanent magnet is expanded.

The invention discloses automatic dust removal equipment for electric energy meters. The automatic dust removal equipment for the electric energy meters comprises a rack, a conveying device and a dust removal device. The automatic dust removal equipment is characterized in that the conveying device and the dust removal device are arranged on the front part and the rear part of the rack in parallel; the dust removal device comprises a location fixture used for fixing the plurality of electric energy meters, an air-blowing device and a turnover mechanism used for driving the location fixture to turn over up and down; and a transferring-loading mechanism is further arranged above the rack, and between the conveying device and the location fixture, and used for grabbing the electric energy meters to be subjected to dust removal on the conveying device and moving the electric energy meters onto the location fixture or grabbing the electric energy meters subjected to dust removal on the location fixture and moving the electric energy meters onto the conveying device. According to the automatic dust removal equipment for the electric energy meters, the conveying device and the dust removal device are mutually separated, so that dust in the electric energy meters can be adequately eliminated.

This wig fastening tool is formed by connecting and fixing two substantially U-shaped members to each other. Each substantially U-shaped member is constituted of a comb-teeth fixation piece (11) having comb teeth (20) fixed thereto and two curved elastic shanks (12 and 13) extending in the same direction substantially perpendicularly from the opposite ends of the comb-teeth fixation piece. In a state where openings (15) of the two substantially U-shaped members face each other and the curved elastic shanks (12 and 13) thereof overlap each other, the two substantially U-shaped members are fixed to each other at a plurality of fixation locations distributed in the direction in which the overlapping curved elastic shanks (12 and 13) extend. Thus, the two members have high elastic deformability and high unity. In a case where the wig fastening tool (S) is manually recurved, if one of the substantially U-shaped members (10) recurves, the other substantially U-shaped member (10) would always recurve likewise (i.e., only a single recurving operation is sufficient).

An apparatus for the turning of pages of a bound book, comprising a fixture to hold the book, a paper fluffer for blowing air between individual pages of the held book and displacing at least a top page of the held book upwardly, and an air plenum positioned above the top page of the book for grasping and turning the top page by application of a vacuum to the top page.

The invention discloses a turnover device for a lime-cement solidification box, relating to the technical field of lime-cement solidification boxes. The turnover device comprises a box body, and is characterized by further comprising turnover devices arranged at the both ends of the box body, wherein rotary shafts are fixed at the both ends of the box body, and the fixed rotary shafts are located at diagonal positions on the end surface of the box body; the turnover device comprises a support, a middle rotary shaft arranged below the support, and a rotary plate arranged on the middle rotary shaft, wherein shaft grooves are symmetrically arranged at the both ends of the rotary plate; and the fixed rotary shafts are located in the shaft grooves, wherein one fixed rotary shaft is connected with a hydraulic cylinder via a shaft sleeve, the hydraulic cylinder is fixed on the support, the other fixed rotary shaft is connected with a guide rod via a shaft sleeve, and the guide rod is connected with a guide block arranged on the support. The turnover device for a lime-cement solidification box disclosed by the invention is convenient to unload, easy to operate, capable of automatically realizing turnover, time-saving and labour-saving, as well as stable, reliable and easy to locate during turnover.

The invention discloses a trolley overturning mechanism for an accumulation conveyor. The mechanism is characterized in that an overturning chain wheel and a driving chain wheel are arranged at different positions of a transmission shaft respectively, wherein a circulating chain is meshed with the driving chain wheel; a conveying trolley is supported on a trolley rail through a group of front-end guide wheels and a group of rear-end guide wheels, which are arranged at the bottom of the conveying trolley; an overturning pin shaft is arranged at the bottom of the conveying trolley, and is meshed with the overturning chain wheel; a wheel shaft is arranged at the bottom of the conveying trolley through a bracket; a trolley chain wheel meshed with the circulating chain is arranged on the wheel shaft; a static pressure plate is arranged on one side of the trolley chain wheel, and is pressed against the end face of the trolley chain wheel by virtue of pretightening force through a spring sleeved on the wheel shaft and a nut tightened at the end of the wheel shaft to produce end face static pressure on the trolley chain wheel. The trolley overturning mechanism for the accumulation conveyor is used for the accumulation and the overturning of the trolley on the accumulation conveyor, and the accumulation and overturning reliability of the trolley can be ensured.
