Description

Two gear planetary gear oil drilling winch

technical field

The utility model belongs to the technical field of oil drilling and relates to a two-speed planetary gear oil drilling drawworks. the

Background technique

Most of the existing oil drilling drawworks are difficult to install and transport due to their large size and heavy weight, which add a lot of extra costs and restrictions, and also cause waste of space on the drilling floor and raw materials. Two-speed drawworks has many advantages over one-speed drawworks in function. It can reduce the total installed power of the drawworks, improve work efficiency, and meet the requirements of different drilling conditions. The two-speed winch is the development trend of the AC variable frequency winch. However, if the planetary transmission is simply used to realize the two-speed transmission function, it is very difficult to realize the high-power transmission, and the transmission ratio is not ideal enough, the reliability of the transmission is greatly reduced, and the maintenance is very difficult. the

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments. the

As shown in Figure 1, the structure of the two-speed planetary gear oil drilling drawworks of the present utility model is: the main motor 1 and the auxiliary motor 11 of AC frequency conversion are respectively connected with the cylindrical gear box 2 through a drum-shaped tooth coupling 4, and the cylindrical gear box 2 is connected with the cylindrical gear box. The planetary gearbox 5 is connected as a whole through the ring gear 7, the tooth clutch 3 inside the cylindrical gearbox 2 is connected with the planetary carrier 6 inside the planetary gearbox 5, the planetary carrier 6 is connected with the roller shaft 9 through a key, and the roller shaft 9 A drum body 10 and hydraulic disc brakes 8 for winch brakes are provided. the

The cylindrical gearbox 2 can realize power paralleling and two-speed shifting functions. The speed change is realized through the tooth clutch 3. The motor and the cylindrical gearbox 2 are connected through the drum-shaped gear coupling 4, and the soy-shaped gear coupling is used. 4 can reduce the installation accuracy of the power input shaft. The planetary gearbox 5 realizes deceleration and power output. The planet carrier 6 of the planetary gearbox and the roller shaft 9 are connected by a key to complete the power output. The cylindrical gearbox 2 and the planetary gearbox 5 are connected as a whole through the ring gear 7 and share a lubricating oil road. The winch brake is realized by hydraulic disc brake 8 and motor 1 energy consumption braking, and the main motor 1 or auxiliary motor 11 is used to realize automatic drilling. the

The winch of the utility model can be laid out in a variety of structural forms. For example, according to the needs of the winch power, the power of one motor can be input from one side, and the power of two motors can be input from both sides simultaneously. Hydraulic disc brakes can be flexibly equipped with one side or two sides. the

As shown in Figure 2, the structure of another embodiment of the winch of the present invention is: the power input of the double motor 1 to the cylindrical gear box 2 through the bean-shaped gear coupling 4, the cylindrical gear box 2 is composed of two input shafts and It consists of an intermediate shaft assembly, two input shafts are symmetrically arranged in the center, and the cylindrical gearbox 2 acts as a speed changer, dividing the speed into two gears, high and low.
