Self-propelled drilling rig "dasha"
(57) Abstract:The invention relates to the field of drilling rigs and can be used for transportation of goods, pipe laying and road construction on wetlands. The inventive drilling rig contains two or more of the cargo platform, the hull of which have the shape of a comb, in the space between the teeth which are inserted movable elements between which and the casing installed cushion of elastic material, while the loading platform connected to the power cylinders double acting for reciprocal movement relative to each other. The invention provides for the preservation of the swamp as a natural area along the path of movement of self-propelled drilling rig. 2 Il. The invention relates to the field of self-propelled drilling rigs and can be used for transportation of goods, pipe laying and road construction on wetlands Tyumen and other regions.Known drilling rig for swamp and lake areas.with. 331167, MKI E 21 B 7/02, 1972), including two flat-bottomed platform on which evenly mass is the necessary equipment, connected to each other by power cylinders and provided with the PTA at all depths, inflicting fatal damage.The aim of the invention is the preservation of the swamp as a natural area along the path of movement of self-propelled drilling rig.To achieve the goal of self-propelled drilling rig for swampy areas contains two or more cargo platform, United power cylinders double-acting, drilling equipment, while supporting surface of housings each platform has the form of a comb, in the space between the teeth which are inserted movable elements between which and the casing installed cushion of elastic material.In Fig. 1 shows a self-propelled drilling rig during the drilling of the well; Fig.2 - in the process.Self-propelled drilling rig made in the form of two 1 and 2 (Fig.1) and more platforms, the United power cylinders 3 double acting ball bearings, and the bearing surface of the housings 4 and 5 has the shape of a comb, in the space between the teeth which are inserted movable elements 6 and 7, resting one end on the surface of the swamp, and the other on the hollow inside of the cushion 8 of elastic material. On platforms evenly on weight placed drilling equipment, si is edusim way.During the drilling of wells (Fig.1) platforms 1 and 2 as close as possible to each other and chassis platforms 4 and 5 are recessed to a certain depth into the swamp. This depth is determined by the position on the surface of the movable elements 6 and 7 and the locking device 9 in the absence of any pressure in the cavity of the pillow 8.After self-propelled drilling rig begins moving through the swamp as follows (Fig.2).In the cavity of the cushion 8 creates excess pressure through the elastic wall is transmitted to the movable elements 6 and the housing 4 of the platform 1, causing the latter to rise to the surface of the bog. Power cylinders 3 are nominated, and platform 1 moves away from the platform 2, which occupies a more stable position due to continued immersion of the body 5 in the swamp. The pressure in the cushion 8 is reduced to zero, and the platform 1 is immersed in a swamp. Then the excess pressure in the cavity of the cushion platform 2, which POPs up, and the power cylinder 3 is lifted to the platform 1. Then the process repeats.Thus, the destruction is subjected to only the surface of the bog, and the bog remains intact. Self-propelled drilling ustane double acting, drilling equipment, characterized in that the bearing surface of housings each platform has the form of a comb, in the space between the teeth which are inserted movable elements between which and the casing installed cushion of elastic material.
SUBSTANCE: at first and second stages of motion, length of supports (2) and (3) is varied. At the same time the chassis length is changed. Also combined bearing (13) is used to vary angular position of chassis components relative to each other. All aforesaid changes are coordinated in time and size to ensure smooth translation of truck cabin (4) along horizontal line.
EFFECT: improved smoothness of truck cabin motion.
