Embodiment Construction

[0021] A five-way oil circuit structure for a top-drive variable-frequency and variable-speed asynchronous motor brake includes an oil circuit five-way 1 with a cavity structure inside; one side wall of the oil circuit five-way 1 is provided with an oil inlet 2, and Four oil outlets 3 are opened on the other side wall of the oil passage bottom bracket 1 opposite to the side wall provided with the oil inlet 2.

[0022] An oil outlet pipe 4 is connected to each of the four oil outlets 3.

[0023] The oil outlet pipe 4 and the oil outlet 3 are connected by a threaded structure.

[0024] The oil channel bottom bracket 1 is welded by high-strength steel plate and has a rectangular shape; the oil inlet 2 is opened on one of the two largest sides of the rectangle, and the four oil outlets 3 are opened on the other largest side. Above and close to the four corners of the side respectively (such as figure 1 , 4 Shown).

[0025] The oil channel bottom bracket 1 is provided with a pair of thro...

Abstract

The invention relates to an oil way for a top drive motor braking device, in particular to a five-way oil way structure of a frequency control asynchronous motor brake for a top drive, and solves the technical problems of complex oil way structure, higher cost and unbalanced oil way distribution length in a traditional top drive motor brake. The five-way oil way structure of the frequency control asynchronous motor brake for the top drive comprises an oil way five-way with the internal as a cavity structure; an oil inlet is formed in one side wall of the oil way five-way; and four oil outlets are formed in the other side wall opposite to the side wall, with the oil inlet, of the oil way five-way. The four oil outlets are respectively connected with oil outlet pipes. The five-way oil way structure of the frequency control asynchronous motor brake for the top drive simplifies the brake oil way system, improves the operation convenience of installation and maintenance and the stability of the brake system, is simple in structure and parts, reduces the production cost, and is excellent in economic benefit.

Description

Technical field [0001] The invention relates to an oil circuit used in a brake device of a top drive motor, in particular to a five-way oil circuit structure of a frequency conversion speed regulating asynchronous motor brake for top drive. Background technique [0002] Since its inception in 1982, the top drive drilling device has been widely adopted by countries all over the world due to its good drilling performance and adaptability, and has gradually become an important configuration and development direction of modern drilling rigs. With the development of top drive technology, the requirements for top drive motors are becoming more and more stringent-the overall size is small, the structure is compact and reasonable, the protection performance is high, the mechanical braking device is equipped, the performance is reliable and the maintenance is easy. [0003] For the mechanical braking device of the top drive motor, a pair of brakes are usually installed symmetrically, which ...
