Description
Technical field
The utility model relates to a kind of Portable hoisting device, relates in particular to the Portable hoisting device that in the roadway of a kind of colliery, pipeline mounting construction is used.
Background technology
In the roadway of colliery, in pipeline mounting construction, the underground construction working space is relatively narrow.It is mainly to take the down-hole pipe installation exercise as main that wind, dustproof pipeline improvement project work progress are pressed in the track lane.According to ore deposit side and design plan requirement, down-hole pipe adopts Φ 159*6 solid drawn pipe welding assembly, and hang along top, tunnel or lateral wall, the weight of Φ 159*6 solid drawn pipe is 22.64kg/m, for guaranteeing welding quality and arrangement and method for construction requirement, steel pipe need to carry out the short tube adjustment in ground location (bottom surface, tunnel), align, weld after, then long tube be lifted to predetermined altitude welded.Like this, every of the long tube after connection is greatly about the 10m left and right, and weight is in the 200kg left and right.According to construction experience in the past, when pipeline is installed welding, first with manpower, pipe is lifted to design height, the construction operation personnel also must be under the condition of heavy burden to pipeline aligned, the operations such as levelling, adjustment, welding.Because the pipeline installation site is relatively high and be subject to the restriction of underground construction operating condition, can't set up scaffold, while using ladder, fork ladder in construction, because of the bottom surface unfairness, ladder is laid not firm, easily causes safety misadventure and the artificial lifting installation effectiveness of pipeline during construction operation lower.This operational method not only needs to take a large amount of manpowers, and the construction operation personnel very easily cause personnel's fatigue due to the heavy burden of ascending a height for a long time, and then directly has influence on the aspects such as job schedule, safety management, quality management.
Because pipeline mounting construction in the roadway of colliery is subject to the restriction of multiple objective condition, can not use common elevator machinery, and each roadway section, highly, the shape difference at width, the gradient and top, can not make fixing elevator machinery.
Be subject to the restriction of multiple objective condition just because of pipeline mounting construction in the roadway of colliery, can not use common elevator machinery, and each roadway section, highly, the shape difference at width, the gradient and top, can not make fixing elevator machinery.This just need to be adjusted according to different construction environments, can adapt to the execution conditions of differing heights, the gradient and respective load, has met to the full extent the requirement of down-hole pipe installation.

The specific embodiment
Embodiment:
1, scheme foundation
Product design relevant with relevant criterion according to national standard regulation, and Specification and the requirement of down-hole lifting construction demand.
1.1 equipment basic fundamental specifications parameter
2, the equipment key components and parts is selected
2.1 winch 1 is selected (HGS-B1000B) type minisize electric hoist that specified lifting weight is 1000kg; this kind of minisize electric hoist is when meeting daily down-hole pipe lifting operation needs; also specifically have that safety factor is good, own wt is light, peace is torn the characteristics such as convenient in carrying open; this minisize electric hoist has adopted explosion-proof electric machine; and Jack is also with fender guards such as dead electricity self-actuating brake, overload and overwinding-proofs, and then avoid in lifting process because occurring that accident is fallen weight and hurted sb.'s feelings.
2.2 expansion link sliding sleeve, expansion link 4, fixed support (truss 3) are selected common steel tube, Φ 32 steel pipes are selected in the main body part of the force of truss 3, structure division Φ 20 steel pipes.As shown in Figure 3, the expansion link sliding sleeve is the sliding sleeve of truss 3 steel pipe upper end, left and right sides welding, Φ 32 steel pipes that the length of sliding sleeve is 50～80mm.Select this shape steel tube to there is raw MAT'L source abundance, make the characteristics such as easy to process, when meeting the device fabrication requirement, can effectively save the device fabrication cost.
2.3 rail meter 5 selects (A3) structural section to be processed into, and meets the standard code manufactured and designed, and meets the routine demand.
