Embodiment Construction

[0023] Referring to Fig. 1 to Fig. 3, the present invention is a large-scale multi-point hydraulically driven hoist, especially a large-scale six-point hydraulically driven hoist, which is equipped with a base 1, a side bracket 2, a beam 3, a double drum 4, and a large gear at the end 5. Steel wire rope and hydraulic turning device7. The side supports 2 are arranged on two sides, and the two side supports 2 are connected by two upper beams 3 to form an integral frame structure.

[0024] Hydraulic rotary device 7 is made up of low-speed high-torque hydraulic motor, brake, planetary reducer and pinion. Six hydraulic swivel devices 7 are arranged on two side supports 2 respectively, and three hydraulic swivel devices 7 are arranged on each side support 2 . The pinion gears of the hydraulic slewing device 7 are arranged in equilateral triangle positions, and are meshed with the terminal bull gears 5 located on both sides of the duplex reel 4 to form an open gear transmission syst...

Abstract

The large multipoint hydraulically driven winch includes a pedestal, side racks, crossbeams, a dual reel, an end large gear, a steel cable and hydraulic reversing gears. Two side racks are connected with two crossbeams to form one integral frame structure; six hydraulic reversing gears comprising hydraulic motor, brake, planetary speed reducer and small gear each are mounted separately onto two side racks; the small gears in three hydraulic reversing gears on the same side rack are arranged in the form of an equilateral triangle and meshed with the large gear to form one opened gear transmission system; and the hydraulic motors convert the hydraulic power into mechanical rotating power transmitted through the small gears to the large gear. The multipoint driving system has equal driving forces to the reel in different points, optimal hydraulic driving characteristic and other advantages.

Description

technical field [0001] The invention relates to a winch, in particular to a large multi-point hydraulic drive winch. Background technique [0002] Existing large hoists are generally driven by single-point geared motors, and their shortcomings include the following: [0003] 1. The hoist is subjected to a single point of force, resulting in uneven and unreasonable distribution of force points, which makes the overall structure of the force state unsatisfactory. [0004] 2. When the gear motor is used to drive, it is impossible to achieve accurate multi-point force synchronous drive. [0005] 3. The hoist is driven by a single point, so that the large gear at the end must be high in strength and large in size, and its manufacturing process is poor and the production cost is high. [0006] 4. After adopting single-point drive, if the drive point fails, the whole winch will not work, which reduces the safety and reliability of the equipment. [0007] 5. After the single-poin...
