Problems solved by technology

[0002] The input shaft of the existing workover rig is arranged vertically and the output shaft is arranged horizontally because of the angular transmission box. The shaft head of the input shaft comes out from the bottom of the box body. Lubrication solves the problem of bearing and gear lubrication, but the seal of the input shaft has been soaked in the oil pool for a long time, and the workover rig is mainly used in plains, hills, mountains, Gobi, desert edges (including desert hinterlands with road access) and other fields , the environment is harsh, and the angle transmission box is arranged at a higher position from the ground, 3 to 5 meters away from the ground. Due to the internal sealing structure of the angle transmission box, there is oil leakage from the input shaft of the angle transmission box during operation. On the other hand, due to The angle transmission box is arranged high above the ground, and the lubricating oil in the box cannot be replenished in time, and other failures are caused by oil leakage, which leads to the malfunction of the workover rig

Embodiment 1

[0020] With reference to the accompanying drawings in the description, the present invention provides an angular transmission box for a workover rig, a kind of angular transmission box for a workover rig, comprising a vertical box body, an input shaft mechanism and an An output shaft mechanism, and a lubrication system for lubricating the input shaft mechanism and the output shaft mechanism, wherein the input shaft 1 drives the output shaft 2 to rotate through a spiral bevel gear, and the external gear pump 16 is arranged on the outside of the box Below the output shaft 2, the external gear pump 16 is driven by the bridge gear in the box; the oil inlet of the external gear pump 16 communicates with the external oil tank 9 installed under the external gear pump through the oil inlet pipe 13, and the external gear pump A self-sealing filter 12 is provided between the oil tank 9 and the oil inlet pipe 13; the oil outlet of the external gear pump 16 is connected to the oil circuit ...

Embodiment 2

[0029] The main structure is the same as that of Embodiment 1, with the addition of a lubrication electrical control system.

[0030] The safety valve on the oil pump is set to a pressure of 10 bar to prevent damage to system components due to excessive pressure.

[0031] When the lubricating oil temperature is low or when the pressure difference of the filter element is greater than 4bar, the check valve on the filter element is opened, and the hydraulic oil only passes through 50μ coarse filtration; when the temperature rises gradually and the pressure difference of the filter element is lower than 4bar, the hydraulic oil passes through 10μ and 50μ two-stage filtration. In any case, unfiltered hydraulic oil must never enter the lubricating parts of the angle gearbox. When the temperature of the oil pool is lower than 30°C, the alarm signal of the differential pressure transmitter of the filter is invalid; and when the temperature of the oil pool exceeds 30°C, when the press...

Abstract

The invention discloses an angle transmission box for a workover rig, belonging to the technical field of angle transmission boxes, comprising a vertical box body, an input shaft mechanism and an output shaft mechanism installed in the vertical box body in an orthogonal manner, and a A lubrication system for lubricating the input shaft mechanism and the output shaft mechanism. The invention has the characteristics of good sealing and no oil leakage, and the lubricating oil in the angle transmission box can be replenished in time.

Description

technical field [0001] The invention relates to an angle transmission box for a workover rig, belonging to the technical field of angle transmission boxes. Background technique [0002] The input shaft of the existing workover rig is arranged vertically and the output shaft is arranged horizontally because of the angular transmission box. The shaft head of the input shaft comes out from the bottom of the box body. Lubrication solves the problem of bearing and gear lubrication, but the seal of the input shaft has been soaked in the oil pool for a long time, and the workover rig is mainly used in plains, hills, mountains, Gobi, desert edges (including desert hinterlands with road access) and other fields , the environment is harsh, and the angle transmission box is arranged at a higher position from the ground, 3 to 5 meters away from the ground. Due to the internal sealing structure of the angle transmission box, there is oil leakage from the input shaft of the angle transmis...
