Fully-sealed follow-up sealed flatcar for engineering drilling machine

Abstract

The invention relates to a fully-sealed follow-up sealed flatcar for an engineering drilling machine. The fully-sealed follow-up sealed flatcar comprises a chassis, wherein a first half-sealed flatcar and a second half-sealed flatcar which move relative to the center of the chassis in an opened and closed translational motion manner are embedded into the chassis; the first half-sealed flatcar and the second half-sealed flatcar both consist of sealing beams, middle sealed platforms and end part sealed platforms in sequence from the center to outside of the drilling machine; the sealing beam is hinged to the middle sealed platforms; the middle sealed platforms are hinged to the end part sealed platforms; the end part sealed platforms are hinged to the chassis; turnover plates are arranged above the middle sealed platforms and above the end part sealed platforms; the right ends of the turnover plates are hinged to the end part sealed platforms; the left ends of the turnover plates are in lap joint with the middle sealed platforms; a push device which is horizontally arranged is connected between the left and right sides of the sealing beams and the chassis. By adopting the fully-sealed follow-up sealed flatcar, security of operators and facilities on the sealed flatcar can be effectively ensured, and meanwhile, the minimum working space on the chassis of the engineering drilling machine is also achieved.

Description

technical field [0001] The invention relates to the technical field of engineering drilling rigs, in particular to a fully enclosed follow-up sealing flat car for engineering drilling rigs. Background technique [0002] All large-scale engineering drilling rigs have a chassis, and the chassis is generally composed of four steel beams connected end to end to form a square frame, and a pair of platforms (beams) that can be opened and closed relative to the center of the chassis are embedded in the hollow of the frame. , The platform (beam) combined with translational movement is the sealing flat car. The sealing flat car is mainly designed for lifting and lowering the drilling tools, carrying the weight of the drilling tools, and it is also the operating platform for the construction personnel to carry out the lifting and lowering operations on the drilling tools. . [0003] The sealing flat car is composed of two semi-sealing flat cars, which are symmetrically arranged on bo...

AI Technical Summary

Problems solved by technology

However, there is a major defect in the sealing flat car of the shaft drilling rig and engineering drilling rig currently used: the sealing flat car often needs to move along the slideway due to the needs of the drilling process, so there is always a gap between the sealing flat car and the beams at both ends of the chassis of the drilling rig. A large gap is difficult to close, which will easily lead to the fall of personnel and facilities on the sealing flat car (the engineering drilling rig is lifted up to 20 meters high by a single steel casing)
