The invention relates to method for hoisting a large-size workpiece in an ordinary plant and hydraulic jacking equipment thereof. The invention is characterized in that hydraulic lifting devices of a hydraulic jacking system are erected above hydraulic jacking towers through a hoisting beam; the equipment is lifted to a platform height by the hydraulic lifting devices and then sent above a foundation, and the jacking towers are lowered to enable the equipment to take place; a hook used in the combined hoisting beam is connected with a hook beam through a two-way pin shaft, and the hook can rotate to realize rotating operations of a stator. The hydraulic jacking equipment comprises four hydraulic jacking towers, four hydraulic lifting devices, the combined hoisting beam, two tracks and a control board, wherein the four hydraulic jacking towers are respectively arranged above the two tracks to form a framework structure; sectional telescopic mechanisms are arranged in the hydraulic jacking towers, and telescopic control ends of the sectional telescopic mechanisms are connected with an output end of a hydraulic drive mechanism; the lower parts of the hydraulic jacking towers are provided with travelling wheels; and drive input ends of the travelling wheels are connected with a drive output end of a motor. The invention organically combines the hydraulic jacking system with a working principle integrating machines, electricity and liquid and has the characteristics of stable action, safety, reliability, large hoisting weight, convenient mounting and dismounting and obvious economic benefit.

The integrated drawer slide rail assembly of the present invention adopts an overall structure in which the three-section track is integrally connected with the plastic support frame, and the sliding support frame is fixed on the drawer, while the fixed support frame is fixed on the compartment where the above-mentioned drawer is used. On the side wall, to realize the positioning and installation of the overall slide rail device. A plastic support frame is connected to both sides of the three-section track, and the support frame is directly positioned and fastened. The connection structure of the same material is tight, not easy to loose or disjoint, and the two sides of the drawer using the integrated slide rail assembly are easy to position horizontally. , can ensure that the slide rail components on both sides of the drawer are at the same level, effectively reducing the resistance and noise of pushing and pulling the drawer.

The invention discloses a convenient electric cabinet for electric engineering. The electric cabinet comprises a cabinet body, an installation rack is arranged at the upper side in the cabinet body, the right end of the installation rack is fixed on the right inner wall of the cabinet body; a reinforcing rib is arranged at the lower side of the installation rack; a driving motor is arranged at the left end of the upper side of the installation rack, and the driving motor is a stepping motor; a gear is arranged on an output shaft of the driving motor, and a rack is vertically arranged at the center of the upper side in the cabinet body. The convenient electric cabinet for electric engineering disclosed by the invention is capable of automatically keeping out the sun and the rain, and dehumidifying the internal of the cabinet body; the dehumidifying effect is good, the normal work of the electric cabinet is guaranteed, the electric cabinet can be conveniently moved and fixed, and the convenience is high; furthermore, the gap between the observation glass and a cabinet door is reduced so as to effectively prevent external dust an impurity from entering the electric cabinet.
