Abstract
The utility model relates to coal mine drilling devices, in particular to a salvage device special for a kilometer drilling machine hole bottom motor rotor. The salvage device resolves the technical problem of salvage of the motor rotor in coal beds. The salvage device is composed of an outer sleeve and an inner sleeve, wherein the outer sleeve comprises a front sleeve and a rear sleeve, the front end of the front sleeve is a cone-shaped port, and reverse-cone-shaped space is formed inside the front sleeve. The inner sleeve is placed inside the reverse-cone-shaped space, the rear end of the rear sleeve is provided with a drill rod connection port, the front sleeve is connected with the rear sleeve in sleeved mode, and the inner sleeve is a combined cone sleeve made of rubber materials. The salvage device is reasonable in design, effectively resolves the problem of non-loss salvage of the motor rotor from a drill hole, improves using efficiency of a drilling machine, saves a large number of parts, and obtains obvious economic benefit.
Description
Technical field
The present invention relates to a kind of colliery drilling rig, be specially the special-purpose fishing device of motor rotor at the bottom of a kind of km rig hole.
Background technology
Along with the extensive use of km rig in my ore deposit, directed long drilled holes progressively replaces the boring of general brill, and the major diameter of constructing on a large scale, long distance, directional drilling are extremely urgent.Directional drilling construction is taken out pick to alleviation and is adopted the situation that is connected nervous and play a role; For making down the step tunnel the boring that operation in big strides just needs the more major diameter of construction, long distance, could guarantee the operation in big strides that lower whorl tunnels through more macrocyclic extraction.So it is very frequent that the km rig uses; When the boring of construction km rig; Because coal seam geological condition, the situation in cherry coal, the hole of collapsing is for example perhaps unplannedly cut off the water and electricity supply, the perforation phenomenon between branch; The capital causes the bit freezing of drilling tool, the phenomenon generation of embracing brill, pressure brill; Even the brill accident appears falling, and because being pressed between rotor and the stator of motor at the bottom of the hole, the transporting water of water pump forms powerful reaction torque power again simultaneously, cause at the bottom of the hole the anterior driving rotor threaded connection place of motor caused by reaction torque power and thread off motor rotor.For being taken out, motor rotor repeats to utilize again; Need salvage processing, the special construction of motor rotor and special cooperation requirement at the bottom of the hole, rotor profile is the fried dough twist type; With stator is that cycloid cooperates; Traditional mantle fiber drags for the surface configuration that tool damages motor rotor at the bottom of the hole easily, and its damage can not be re-used, thereby increases the expense of accessory cost.
Summary of the invention
The present invention is in order to solve the technical problem that motor rotor is salvaged in the coal seam, the special-purpose fishing device of motor rotor at the bottom of a kind of km rig hole is provided.
The present invention is realized that by following technical scheme the special-purpose fishing device of motor rotor is made up of overcoat and interior cover at the bottom of a kind of km rig hole; Overcoat comprises protheca and back cover, and the protheca front end is a bell, and the inboard is reverse cone space; Cover in placing in the cone space; Cover rear end, back is provided with the drilling rod connector, socket between protheca and the back cover, and described interior cover is an elastomeric material combination tapered sleeve.
The present invention is applicable to that salvaging the km rig falls into motor rotor at the bottom of the hole in the extraction boring in work progress.The back cover is connected with drilling rod, and delivers to the motor rotor place in the boring through drilling rod, and the taper running-on of protheca gets into the motor rotor guiding in the inner interior cover; Interior cover moves forward, and receives the frictional force effect, and interior cover moves backward; Interior cover enlarged-diameter encases motor rotor fully.Draw this device is outer then, in be enclosed within the function of friction, move forward; Diameter diminishes motor rotor is held tightly under inclined-plane pressure, thereby motor rotor is pulled out, because interior cover is an elastomeric material; So can motor rotor not damaged; Certainly the interior cover of elastomeric material uses back damage several times, and we separate overcoat, and cover is promptly reusable in changing again.
Reasonable in design of the present invention efficiently solves the problem that the free of losses of motor rotor from boring salvaged, and has improved the service efficiency of rig, has practiced thrift a large amount of accessories, has remarkable economic efficiency.
Description of drawings
Fig. 1 is a structural representation of the present invention
Fig. 2 is the A-A sectional drawing of Fig. 1
Among the figure: cover, 5-drilling rod behind 1-motor rotor, 2-protheca, the interior cover of 3-, the 4-.
The specific embodiment
Like Fig. 1,2 signals, the special-purpose fishing device of motor rotor is made up of overcoat and interior cover at the bottom of a kind of km rig hole; Overcoat comprises protheca 2 and back cover 4, and protheca 2 front ends are bell, and the inboard is reverse cone space; Cover 3 in placing in the cone space; Cover 4 rear ends, back are provided with the drilling rod connector, socket between protheca and the back cover, and described interior cover 3 is an elastomeric material combination tapered sleeve.
Meaning as shown in Figure 2, described in cover 3 by three arc body involutory compositions.Reaming is easier.
Economic benefit: motor is practiced thrift 130,000 yuan at the bottom of successfully salvaging a hole, successfully salvages motor at the bottom of 3 root holes last year, successfully salvages 4 this year, reduces expenses 910,000 yuan altogether.
