Abstract

The invention relates to a shift device for a riding wheel of an oil extractor with a closed tank body, in particular to a transmission device of an oil extractor with a closed tank body used for the oil exploitation of an oil field, and the patent number is 200910010035.2. The upmost end of a machine body is provided with a device for forwardly and backwardly shifting a rotary wheel or a riding wheel. In the operation of repairing a well, the riding wheel can be shifted from the front position to the back position of the upper end of the machine body. In the operation of oil exploitation, the riding wheel on the back position of the upper end of the machine body can be moved to the front position of the upper end of the machine body. A shifting bolt in front of the device is used for upwardly rotation to support the front end of a toothed bar to upwardly move to incline the toothed bar, and the riding wheel is forced to backwardly move. When the riding wheel needs to forwardly move, the shifting bolt on the front position downwardly rotates into a screw hole and upwardly rotates by the shifting bolt on the back position, the shifting bolt on the back position supports the toothed bar to forwardly incline to enable a gear to forwardly move, and both ends of a riding wheel shaft are screwed to assist the movement of the gear.

Description

Technical field: [0001] The supporting wheel shifting device of a closed box pumping unit belongs to a rotating wheel or a supporting wheel shifting device arranged on the top of a body of a closed box pumping unit used for oil production in an oil field. Background technique: [0002] It is known that the transmission device of the closed box pumping unit used for oil production in the oil field, patent number: 200910010035.2, the rotating wheel or supporting wheel arranged at the uppermost end of the body, because it is fixed at the front and upper position of the body, during the workover process, The workover equipment is difficult to be arranged on the top of the oil well, which brings great difficulties to the workover operation. Invention content: [0003] The purpose of the present invention is to provide a transmission device for a closed box pumping unit, patent number:: 200910010035.2 supporting wheel shifting device, this device is set on the top of the body of...
