Description

Technical Field

[0001] This application relates to the field of petroleum equipment technology, specifically the design of a petroleum top drive motor. Background Technology

[0002] Top drive drilling rigs (referred to as "oil top drives") are one of the core equipment in modern oil and gas drilling. Their core power component is the top drive motor, which primarily undertakes the functions of drill string rotation drive and torque transmission. The filter grating, as a key component of the air-cooled system of the oil top drive motor, directly affects the motor's protection performance, heat dissipation efficiency, and service life. In existing technologies, a traditional structure of a single-layer fixed grating combined with a filter screen is typically used. However, this presents a problem of conflict between filtration efficiency and ventilation volume, and it cannot adapt to different operating conditions. Therefore, a new oil top drive motor needs to be designed with corresponding improvements to its air-cooled filter grating, allowing it to adjust the number of layers of the built-in filter screen according to operating conditions, thereby achieving adjustment of the filtration effect. Summary of the Invention

[0003] A petroleum top drive motor includes at least a rectangular housing, with air inlet windows on all four sides of the upper half of the housing, and each air inlet window having a grille assembly.

[0004] The grille assembly includes an outer grille panel, an inner mesh panel, and a connecting bracket.

[0005] The outer grating plate includes a fixed plate body with grating horizontal holes distributed on the fixed plate body. A grating guide plate is provided along the lower edge of the grating horizontal holes. A mesh plate plug is provided at each of the four corners of the front end face of the fixed plate body. The mesh plate plug includes a plug base, a plug end post provided at the stop end of the plug base for insertion into the mesh plate insertion hole, a plug inner hole provided at the stop end of the plug end post, and a second locking groove provided on the inner wall of the plug inner hole.

The socket head also has radially distributed insertion holes circumferentially, and the front end of the radial insertion holes has a side connecting hole communicating with the sliding insertion hole.

[0010] The pressure-bearing component includes a pressure-bearing slide cylinder slidably disposed within a socket hole, an anti-rotation key formed on the outer wall of the pressure-bearing slide cylinder and inserted into the anti-rotation key hole, a drive plug formed on the inner wall of the anti-rotation key, a sliding inner rod sleeved within the pressure-bearing slide cylinder, an arc-shaped inclined groove disposed on the outer wall of the sliding inner rod and cooperating with the drive plug, a limiting ring groove formed on the rear end of the outer wall of the sliding inner rod and cooperating with the limiting protrusion ring, and planar inclined holes evenly distributed circumferentially on the rear end of the sliding inner rod.

[0037] The petroleum top drive motor described in this case features a grid assembly 8 whose number of built-in mesh plates 82 can be adjusted to regulate the filtration effect on external mud and dust, and it is easy to operate. S1, Install the first built-in mesh plate 82 and the connecting bracket 83: Move the built-in mesh plate 82 from front to back so that the mesh plate socket 822 of the built-in mesh plate 82 is engaged with the plug end post 8142. Move the connecting bracket 83 from front to back so that the socket head 103 is inserted into the plug inner hole 8143.

The drive plug 23 acts on the arc-shaped inclined groove 25 to make the sliding inner rod 24 and the planar inclined hole 27 rotate. The plane oblique hole 27 rotates, thereby driving the locking component 3 to extend outward. The locking component 3 is inserted into the first locking groove 105 or the second locking groove 8144 to achieve locking and fixation.

[0039] For the last connecting bracket 83, since there are no other connecting brackets 83 in front of it to press and fix it, a C-type retaining ring is required for fixation: Manually press each socket assembly 832 of the foremost connecting bracket 83 to move the pressure-bearing slide 21 backward, thereby achieving radial outward movement of the locking assembly 3. Then, insert a C-shaped retaining ring into the first locking groove 105 to limit the position of the pressure-bearing slide 21, and finally maintain the radially extended posture of the locking assembly 3 to fix the foremost connecting bracket 83.
