Description

A kind of mine underground cable line suspension fixed ladder

Technical field

The utility model relates to a kind of ladders that a kind of underground coal mine is used to hang fixed cable and bus box, belong to mine Use field of tool.

Background technique

Armouring electricity when underground coal mine ascend a height operation, especially in high-altitude hanging wire, for diameter greater than 10cm Cable, length is long, and weight is big, and more people operation simultaneously is needed when raising, and needs to stay aloft a period of time after raising, directly It is hung on top plate completely to cable, encounters when being connected when two cables pass through bus box, need bus box while lifting Height, integrated hanging in the sky, considerably increase the labor intensity of staff, and labor efficiency is extremely low, it would be highly desirable to solve.

Summary of the invention

The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, a kind of convenience is provided and is fixed in suspension in the air Cable and bus box, a kind of mine underground cable line instead of manually lifting lift cable and bus box in the sky, which is hung, to be fixed Ladder.

Technical solution adopted by the utility model to solve its technical problems is a kind of mine underground cable line suspension fixations Ladder, characterized in that whole to be made of ladder and support plate suspended structure, ladder top is inside and outside axle construction, and outer shaft has two branch Support leg, inner shaft have two supporting legs, and inner shaft both ends are located on the inside of outer shaft both ends, and outer shaft is rotated around inner shaft, four supporting legs and Ground three-legged structure together, has limit rope between outer shaft supporting leg and inner shaft supporting leg.

A kind of above-mentioned mine underground cable line hangs fixed ladder, characterized in that crossbar end between two supporting legs of outer shaft Positive position has arc to make contact hook, and there is arc hanged hook on two supporting leg tops of outer shaft.

A kind of above-mentioned mine underground cable line hangs fixed ladder, characterized in that first crossbar between two supporting legs of outer shaft Outboard end has support rod, and there is T-type support rod in the inner shaft end at ladder top both ends, and T-type support bar top has row's arc ring, There is hollow pipe in arc ring, support rod fixing groove is arranged at the T-type support rod bottom of support bar top.

The utility model has the beneficial effects that in use, the armored cable line hung can will be needed to be hanging to top plate Before, the arc for being hanging to above-mentioned cable suspension fixed ladder in advance is made contact on hook, before hanging fixed bus box, can first by The anti-hollow pipe surface being placed between T-type support rod of bus box greatly reduces worker's instead of manually lifting in the sky Labor intensity improves labor efficiency.

Detailed description of the invention

FIG. 1 is a schematic structural view of the utility model.

In figure: 1 arc ring, 2T type support rod, 3 curved supports hook, 4 inner shaft supporting legs, 5 crossbar ends, 6 arcs are made contact Hook, 7 support rods, 8 fixing grooves, 9 stop collars, 10 limit ropes, 11 outer shaft supporting legs, 12 first crossbars, 13 hollow pipes.

Specific embodiment

In use, the outer shaft supporting leg 11 of above-mentioned mine underground cable line suspension fixed ladder and inner shaft supporting leg 4 are unfolded It is supported, armored cable line is highly hanging to arc 6 surface of hook of making contact as needed and will prop up when needing to hang bus box Strut 7 and T-type support rod are raised and support rod 7 is placed in fixing groove 8, penetrate limit rope 10 in stop collar 9, in arc ring 1 Armored cable and bus box can be hanging to after top plate hitch point is properly hung by insertion hollow pipe 13 to bus box is placed On cable hook.

Outer shaft supporting leg 11 and inner shaft supporting leg 4 are made of steel pipe, and above-mentioned mine underground cable line hangs fixed ladder both ends Outer shaft supporting leg 11 and inner shaft supporting leg 4 by the interior axis connection of roller bearing, be welded with hollow steel pipe between the inner shaft of both ends；Outer shaft There is equidistant hole on supporting leg 11 and 4 surface of inner shaft supporting leg, and first crossbar outboard end has welding between two supporting legs of outer shaft There is support rod 7, support rod 7 and hollow pipe 13 are hollow steel pipe, and 12 crossbar end 5 of first crossbar is welded with support rod 7, and first is horizontal Bar 12 can rotate in the hole of outer shaft supporting leg 11；Inner shaft outboard end is welded with T-type support rod 2, and T-type support rod 2 is sky Not busy steel-pipe welding is made, and equidistant arc ring 1 is welded at the top of T-type support rod 2, and arc ring 1 is made of bar bending；Support rod Support rod fixing groove 8 is arranged at the T-type support rod bottom at top, and fixing groove 8 is that steel plate welding is made, and curved support hook 3 is bending Reinforcing bar and outer shaft supporting leg 11 at the top of weld and be made；Arc makes contact hook 6 by being welded to outer shaft two supports after bar bending The positive position of crossbar end between leg.
