Guide rail stepwise type borer motion device

Abstract

A guide rail stepping drilling rig mobile device, which is composed of a translation guide device and a jacking device. The translation guide device is composed of two guide rails (1), a guide slider (2) and a translation cylinder (3). The two guide rails (1 ) are fixed together by the front connecting beam (4), the strut (5) and the rear connecting beam (6), and the guide slider (2) is slidable on the guide rail (1), and is connected with the base of the object to be moved (7). connection, the two ends of the translation cylinder (4) are respectively hinged with the front connecting beam (4) and the base of the object to be moved (7); the jacking cylinder (8) of the jacking device is fixed on the fixed seat (9), and the piston end The crossbeam (10) is connected with the crossbeam (10) through the pin shaft (11), and the crossbeam (10) is fixed on the base of the object to be moved (7). The length of the guide rail of the present invention is not affected by the structure of the base of the object to be moved. By adopting a long guide rail and equipped with a translation cylinder with a large stroke, the large-stroke movement of the object to be moved can be realized economically, and only two translation cylinders are needed, which is especially suitable for The oil drilling rig moves vertically and horizontally as a whole.

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...

Problems solved by technology

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 pressure is large, so The requirements for the foundation are relatively high, and the cement foundation is generally laid; the second is that the length of the guide groove of the translation guide system is affected by the structure of the base, and it is impossible to make it too long. Therefore, the stroke of the translation cylinder of the translation guide system is relatively short; the third is The number of translation cylinders is large, so the synchronization requirements for translation cylinders are relatively high, and the control is difficult
