The invention is concerned with a molding method to fly ash of burning garbage. Add 2 to 15 percent of additive and mix with 5 to 7 percent of water, and make into ball with ball making machine and maintain the ball at nature condition. The formulation of additive is 2 to 10 percent of common portland cement with 425 size or 3 to 10 percent slaked lime and 1 to 5 percent industry syrup. The powder fly ash is disposed into ball by physics and chemistry denaturalization disposal to improve the metallurgy capability of stuff. The lixiviating toxicity of fly ash reduces greatly and the lixiviating concentration to all kind of heavy metal is lower than the standard without the second time of pollution. The anti-press intention of fly ash ball reaches the demand of transport and fusion to separate heavy metal.

The invention discloses a moving box truck special for steel coil transportation. End walls of a body frame are connected with the front end and the back end of the bottom frame, guide rails are arranged on two sides of the bottom frame, and the body frame and a fixing device are arranged on the bottom frame. Three moving sheds are installed on the corresponding guide rails on two sides of the bottom frame through pulley seats on the lower portion of two sides of the moving sheds, the moving sheds are connected in a sleeve mode, locking of the moving sheds is achieved through connection of a stopper and a locking hook between a large and small moving shed assembly and an end wall assembly, a wind hand braking device is installed on the bottom frame, and truck hook buffer devices are installed at two ends of the bottom frame. The moving box truck is capable of achieving complete non-blocking loading and unloading at any opening position. Locking of the moving sheds does not require additional mechanisms and can be achieved by manual pulling force. The fixed device is simple and convenient to operate and ensures that a steel coil is stabilized and not eccentric. The steel coil is loaded and unloaded from the two sides and the upper portion of the truck. The moving box truck is high in mechanical loading and unloading efficiency, quick in truck operation period, good in structural waterproof performance and capable of effectively preventing the steel coil from being corroded and meeting transportation requirements of large heavy objects.

The invention provides a kind of coal transportation with highly effective to guard against corrosion the antifreeze, its component was: Glycol, calcium chloride, triethanolamine, with deionized water. The above coal transportation highly effective anticorrosion antifreeze preparation method includes: (1) solution configuration: The calcium chloride, joins in the deionized water, namely made has been ready to be used the fluid, (2) mixed the process: Joins the triethanolamine makes is ready to be used in the fluid, makes the reserve fluid, again glycol if in the reserve fluid, then continues to stir for a hour, causes the temperature drop to the room temperature, like this, has made the end product. The invention discloses testing many times in the foundation, screened pour point depressant, caused the antifreeze the solidification point greatly to reduce, had achieved -66deg.C, its anti- freezing temperatures has achieved -40deg.C, therefore had the fine low freezing point performance, also the stability was extremely good, has satisfied north the winter coal transportation request. After simultaneously in order to avoid pour point depressant oxidizing corrodes the freight car, but also has used the inhibitor technology, provides the long-term anticorrosion for the train freight car, has guarded against the rust function.

The invention discloses a bracket-free laminated yoke rotor body structure of a hydraulic generator, and aims to solve the technical problem that the radial size of a combined structural yoke rotor body in the prior art is limited so that a rotor bracket cannot be arranged after the diameter of a main shaft and the widths of fanning strips of a yoke are subtracted from the radial size and the like. In the bracket-free laminated yoke rotor body structure of the hydraulic generator, the diameter of a yoke section of the main shaft is increased according to the widths of the fanning strips of the yoke; positioning steps and positioning rib key grooves are machined on the outer circle of the yoke section of the main shaft; and the fanning strips of the yoke are directly laminated on the outercircle of the main shaft, positioned by the positioning steps and then fastened and positioned by radial keys. The bracket-free laminated yoke rotor body structure of the hydraulic generator has the advantages that: the yoke is fixed on the main shaft under the condition of not arranging the rotor bracket, and the technical requirements of the yoke rotor body are met, so that not only the requirements of a high-rotating speed structure are met, but also the requirements of transportation on the structural size and packaging of the rotor yoke can be met.

The invention belongs to the technical field of petroleum equipment, and discloses a derrick that can be closed. It includes a derrick body, which is divided into a left section and a right section. Ear plates, the two sets of connecting ear plates are connected to each other through outer pins and inner pins respectively, the bottom of the other end of the left section and the right section are respectively provided with fixed ear plates, and there are pin holes on the fixed ear plates, pull out the outer pins The rear left section and right section can rotate horizontally around the inner pins. When the pin holes on the fixing lugs coincide, insert the outer pins to fix them. The derrick body is closed to form a quadrilateral with four sides closed. The present invention changes the matching gap between the connecting lug plate and the variable diameter pin through the difference in the installation position of the positioning block on the inner pin, so that the connecting lug plate rotates, and the left section and the right section of the derrick are closed, thereby reducing the volume of the derrick , which not only meets the requirements of railway transportation, but also improves the efficiency of on-site assembly of the derrick.

A movable steel frame for transporting the very long and very heavy steel plates by train is composed of several A-shaped frames consisting of two symmetrical oblique rods and a horizontal bar, and a supporting frames consisting of a horizontal bar with two stop blocks at its both ends and a vertical rod perpendicular to the center of said horizontal bar. Said A-shaped frame is standing up on the horizontal bar of said supporting frame whose vertical rod with a screwed top segment passes through the top point of said A-shaped frame. A rack bar is arranged between two feet of A-shaped frame.
