Abstract

The invention relates to a track step driller mover, wherein it is formed by translate guider and lifter; the translate guider is formed by two tracks (1), guide block (2), and translate cylinder (3); two tracks (1) via front connecting beam (4), support rod (5), and back connecting beam (6) are fixed together; the guide block (2) can slide on the tracks (1), to connect the base of object (7); two ends of translate cylinder (4) are hinged to the base of object (7) and front connecting beam (4); the lifting cylinder (8) of lifter is fixed on the fixed base (9); the piston via pin (11) is connected to the beam (10); the beam (10) is fixed on the base of object (7). The length of track will not be affected by the base structure of object. And it uses long track and translate cylinder with long strike, to reduce the cost, only with two translate cylinders.

Description

Technical field:

[0001] The invention relates to a guide rail stepping drill moving device. Background technique:

[0002] At present, the commonly used stepping moving device in oil drilling rigs is mainly a roller stepping structure, which is mainly composed of a translation guiding system, a jacking system and a hydraulic control system. According to the number of translation cylinders equipped with the translation guiding system, the roller There are two main structures of the step-moving device: one is a translation guide system with four translation cylinders, and the other is a translation guide system with eight translation cylinders. Although the roller stepping moving device has the advantages of small translational resistance and the ability to move the drilling rig vertically and horizontally, it has some shortcomings, mainly as follows: First, the length and width of the guide groove of the translational guiding system are small, and the grounding specific press...
