Example 1:

as shown in the attached drawing 1, the double-hob grille decontamination device comprises a decontamination unit 1 and a retraction unit 3, wherein a cleaning wedge 2 is arranged at the end part of the decontamination unit 1, the cleaning wedge 2 is matched with a guide rail 5, a hob support 9 is arranged on the decontamination unit 1, two sides of the hob support 9 are respectively connected with an outer hob 8 and an inner hob 10, one ends of the outer hob 8 and one end of the inner hob 10 are connected with a transmission component 7, the transmission component 7 is connected with a motor 6, a winch 4 is arranged at the top part of the retraction unit 3, the hob support 9 is connected with a winch 4, and the winch is a light and small hoisting device which uses a winding drum to wind a steel wire rope or a chain to lift or pull heavy objects, and is also called a winch. The hoist can drag the heavy object vertically, horizontally or obliquely. The winding machine is divided into a manual winding machine, an electric winding machine and a hydraulic winding machine. Mainly an electric winch. Can be used independently, can also be used as a component part in machinery such as hoisting, road building, mine hoisting and the like, and is widely applied due to simple operation, large rope winding amount and convenient displacement. The winch is mainly applied to material lifting or horizontal dragging of buildings, hydraulic engineering, forestry, mines, wharfs and the like, and has the following cautions when the winch is used: the steel wire ropes on the winding drum should be arranged orderly, and if overlapping and oblique winding are found, the machine should be stopped and rearranged. The steel wire rope is strictly prohibited to be stepped on by pulling with hands and feet in the rotation process. The steel wire rope must not be completely paid out, and at least three turns of the steel wire rope should be reserved. The steel wire rope must not be knotted or twisted, and should be replaced when the wire breakage exceeds 10% in one pitch. In operation, any person cannot cross the steel wire rope, and after the object (object) is lifted, the operator cannot leave the winch. The object or cage should be lowered to the ground while resting. During operation, drivers and signalers need to keep good visibility with the hoisted object. When power failure occurs during operation, the power supply is cut off, and the lifting object is lowered to the ground. When power is cut off suddenly during operation, the knife switch is pulled open immediately to put down the conveyed object. After the operation is finished, the charging tray is fallen to the ground and the lock box is closed.

The motor 6 drives the inner hob 10 and the outer hob 8 to rotate oppositely through the transmission assembly 7, the transmission assembly 7 can adopt five modes of gear transmission, worm and gear transmission, belt transmission, chain transmission and wheel train transmission, and the applicable circumferential speed and power range of the gear transmission are wide; the transmission ratio is accurate and stable, and the efficiency is high; the working reliability is high and the service life is long; the transmission among parallel shafts, intersecting shafts with any angle and intersecting shafts with any angle can be realized, but the gear transmission has higher requirements on manufacturing and mounting precision and higher cost; it is not suitable for transmission between two long-distance shafts. The turbine worm has large transmission ratio and compact structure size, but has large axial force, easy heating and low efficiency. The belt transmission is suitable for transmission with large center distance between two shafts, has good flexibility, can alleviate impact, absorb vibration, prevent slipping during overload and damage other parts, and has simple structure and low cost. However, the transmission has a large overall size, a tensioning device is required, a fixed and unchangeable transmission ratio cannot be ensured due to slipping, the service life of the conveyor belt is short, and the transmission efficiency is low. Compared with gear transmission, the chain transmission has the advantages of lower requirements on manufacturing and mounting precision, simple transmission structure when the center distance is larger, non-constant instantaneous chain speed and instantaneous transmission ratio and poorer transmission stability. The gear train transmission is mainly suitable for transmission between two shafts which are far away from each other; the gear can be used as a speed changer to realize variable speed transmission; a larger transmission ratio can be obtained; the synthesis and decomposition of the motion are realized. When the concrete transmission assembly is adopted, the five mechanical transmission modes are considered according to the working environment.

The galvanized steel wire rope comprises a hot galvanized steel wire rope and a cold galvanized steel wire rope, and the hot galvanized steel wire rope and the cold galvanized steel wire rope are technically different in that the hot galvanized steel wire rope is coated by physical thermal diffusion, an iron-zinc compound is firstly formed, and a pure zinc layer is sequentially formed on the surface of the iron-zinc compound. The highest zinc content of hot galvanizing is 593g/m 2. The hot galvanizing reduces the mechanical property of the steel wire, and the galvanized steel wire rope with high strength and high corrosion resistance is required and is mostly twisted by adopting the galvanized steel wire. The hot galvanized steel wire rope is a market trend and will become the first choice of galvanized steel wire rope users. Because the hot galvanizing steel wire rope has ultrahigh cost performance. The steel wire of the hot galvanizing steel wire rope forms a coating layer by physical thermal diffusion, firstly forms an iron-zinc compound, and sequentially generates a pure zinc layer on the surface of the iron-zinc compound on the surface of the galvanized steel wire. The highest zinc content of the hot-dip galvanized steel wire rope is not 593g/m 2. The hot dip galvanizing is zinc plated in a zinc liquid with melting temperature of 450 DEG and 480 ℃.
