Problems solved by technology

This process not only delays a lot of time and affects the drilling efficiency of the drilling rig, but also requires at least 2-3 people to complete, especially in the process of putting the drill pipe into the manipulator and recovering the drill pipe, it not only consumes more manpower, but also It will bring a lot of potential safety hazards; in addition, the existing drill pipe placement racks are all low in height due to the supporting manipulator. When the drill pipes are recovered, lifting equipment is required to hoist the drill pipes one by one to the vehicle for transporting the drill pipes. The work is cumbersome and the efficiency is low

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings.

[0016] Such as Figure 1 to Figure 3 As shown, the quick loading and unloading drill pipe device is composed of a drill pipe placement frame, which mainly includes an adjustable bracket, an automatic feeding device and a movable stopper device; the adjustable bracket includes a support leg 1, a connecting beam 2, and a support beam 5. Fixed block 6, bar support plate 7, connecting plate 10 and screw mechanism; three bar support plates 7 are fixed on the inner side of the bracket beam 5 at intervals, and two connecting plates 10 are fixed on three bar support plates 7 Between them, the fixed block 6 is arranged on the left end of the support beam 5, and the two support beams 5 are supported by four legs 1, and the two legs 1 on the left side of the support beam 5 are directly hinged to the corresponding position on the bottom plate of the raise drilling rig. The two ou...

Abstract

The invention discloses a quick mounting and demounting device for a drill stem of a raise boring machine. The quick mounting and demounting device consists of a drill stem holder which comprises an adjustable support, an automatic feeding device and a movable retainer device. The adjustable support comprises a support (1), a connection beam (2), a support crossbeam (5), a fixed retainer (6), a retaining rod support plate (7), a connection plate (10) and a screw mechanism. The automatic feeding device consists of a link mechanism and a cam mechanism, and the movable retainer device comprises a movable retainer (18) and a fixed plate (19). Compared with the prior art, the quick mounting and demounting device for the drill stem is compact in structure and simple in operation, automatic mounting and demounting of large-sized drill stems is realized, labor intensity is effectively relieved for workers, the large-sized drill stems can be quickly put into a manipulator for one time and quickly recovered, and accordingly operation efficiency is remarkably improved. In addition, the whole quick mounting and demounting device is convenient to mount, demount and transport, and the automation level in mounting and demounting of the drill stem of the raise boring machine is evidently increased.

Description

technical field [0001] The invention relates to a device for loading and unloading drill pipes, in particular to a device for quickly loading and unloading drill pipes for a raise drilling rig. Background technique [0002] In recent years, with the continuous advancement of science and technology, the level of mechanization, automation and intelligence of raise drilling rig operations has made great progress. However, the level of automation and intelligence in the loading and unloading of drill pipes for raise drilling rigs needs to be further improved. [0003] At present, most of the domestic large-scale raise drilling rigs are manually operated lifting equipment to send the drill pipe pre-placed on the drill pipe rack into the manipulator, and then the manipulator sends the drill pipe to the drilling center. This process not only delays a lot of time and affects the drilling efficiency of the drilling rig, but also requires at least 2-3 people to complete, especially i...
