Oil vehicle drilling rig turntable angle transmission box

Abstract

The invention discloses a rotary table corner transmission case of a petroleum truck-mounted drilling rig. The rotary table corner transmission case comprises a vertical case main body, an input shaft mechanism, an output shaft mechanism and a lubrication system, wherein the case main body is formed by assembling an upper case body and a lower case body; the input shaft mechanism and the output shaft mechanism are installed in the vertical main case body in an orthogonal mode; the lubrication system is used for lubricating the input shaft mechanism and the output shaft mechanism. A first supporting base which penetrates through the vertical case main body and used for installation of the input shaft mechanism is arranged in the vertical case main body. The lower surface of the upper case body and the upper surface of the lower case body are provided with a second supporting base for installation of the output shaft mechanism. The output shaft mechanism is installed on the side face of the input shaft mechanism. The input shaft mechanism and the first supporting base are in sliding fit. The output shaft mechanism and the second supporting base are in sliding fit. A first gear on the input shaft mechanism is meshed with a second gear on the output shaft mechanism. As the input shaft mechanism is installed in the upper case body and the lower case body though the first supporting base, the airtightness of the vertical case main body is ensured.

Description

technical field [0001] The invention relates to the technical field of petroleum vehicle-mounted drilling rigs, in particular to a turntable angle transmission box of petroleum vehicle-mounted drilling rigs. Background technique [0002] The vehicle-mounted drilling rig is a relatively new loading form of drilling machinery and equipment. It integrates the main drilling equipment and drilling tools into one vehicle, and usually performs drilling operations on the vehicle. Most of the oil mining areas are located in plateaus, deserts, wetlands, swamps and water surface areas. Due to the geographical environment, these places require the input shaft mechanism and output shaft mechanism of the turntable angle transmission box of the vehicle-mounted drilling rig to be located in different boxes to realize power transmission. If the input shaft mechanism and the output shaft mechanism adopt the box-separated design, it is difficult to guarantee the oil tightness of the turntable ...

Problems solved by technology

Most of the oil mining areas are located in plateaus, deserts, wetlands, swamps and water surface areas. Due to the geographical environment, these places require the input shaft mechanism and output shaft mechanism of the turntable angle transmission box of the vehicle-mounted drilling rig to be located in different boxes to realize power transmission. If the input shaft mechanism and the output shaft mechanism adopt a separate box design, it is difficult to guarantee the oil tightness of the turntable angle transmission box

For this reason, the traditional turntable angle transmission box with the input shaft mechanism and output shaft mechanism located in the same side box is still used at present, but the traditional turntable angle transmission box is used for mining, and the turntable angle transmission box has noise during operation The problem of high height and large vibration, and the turntable angle transmission box will generate a lot of heat during the work process, because the existing lubrication system of the turntable angle transmission box is difficult to cool down the various parts of the input shaft mechanism and output shaft mechanism, making the turntable Defects such as unstable working performance and low safety performance of the angle transmission box
