Abstract
The utility model relates to a mine ladder structure which comprises a stand column, footsteps and a supporting rod, wherein the stand column is fixed near to beside a mine wall, and the supporting rod is fixedly connected between the stand column and the mine wall. A plurality of footsteps are arranged in a stair structure and are fixed with the stand column, the stair structure is raised in ladder mode, and the stair structure which is formed by the footsteps in arranged mode is raised around the stand column in an oval shape or a square shape. A guardrail is vertically fixed at the outer end of each footstep, the upper end of the guardrail is fixedly provided with a handrail, a rail is further fixed on the guardrail, and the upper end of the stand column is further provided with a flange. The mine ladder structure has the advantages of being simple and reasonable in structure, reducing processing and assembling of part components, and being frugal in material, light in weight, small in investment and rapid to install compared with a universal vertical shaft ladder.
Description
Technical field
The utility model belongs to the mine safety appliance technical field, relates to a kind of escape way of mine vertical shaft pit shaft, especially a kind of stepladder structure that personnel withdraw during as the down-hole burst accident.
Background technology
The general vertical solar that coal in China is existing mainly is comprised of parts such as ladder, ladder crossbeam, girder, carriage, landing slab, fence, holder hooks, is beam and slab type form of structure; Ladder crossbeam two ends are fixed with the carriage that is anchored in the borehole wall, three girder one ends and the carriage that is anchored in the borehole wall, and the other end links to each other with crossbeam, on crossbeam and the girder landing slab is set; The ladder upper end is connected with the borehole wall or large girder, and lower end and landing slab are fixed, and this form of structure is comparatively complicated with holder, hook fixed fence for three of landing slabs, and consumption of materials is large, and initial investment is high; Member is many, and processing charges is high, and borehole wall perforating is many, and connector is many, and installation period is long.
The utility model content
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, a kind of stepladder structure is provided, the solar of this kind form of structure has simple and reasonable, and reduced processing and the installation of a part of member, relatively general vertical solar possesses that material is economized, lightweight, small investment, effect that installation is fast.
The purpose of this utility model solves by the following technical programs:
This stepladder structure comprises column, pedal and support bar, and described column is fixed in by the borehole wall, and described support bar is fixedly connected between column and the borehole wall, and some pedals are arranged as the staircase structure of ladder rising and fix with column; The staircase structure of being arranged by pedal is the structure around column ovalisation or square rising.Outer end at each pedal vertically is fixed with guardrail, and the upper end of described guardrail is fixed with handrail.Also be fixed with fence on the described guardrail.The upper end of described column also is provided with flange.
Support bar fixed pedestal or fence or handrail or the column of stepladder structure of the present utility model by being fixed in the borehole wall, form the gusseted rock-steady structure, the utility model takes full advantage of the Structural Tectonics of ladder, by increase column, support bar solar is carried out more efficiently simplification.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein: 1 is pedal; 2 is guardrail; 3 is fence; 4 is handrail; 5 is support bar; 6 is column; 7 is flange.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1, stepladder structure of the present utility model comprises column 6, pedal 1 and support bar 5, and described column 6 is fixed in by the borehole wall, described support bar 5 is fixedly connected between column 6 and the borehole wall, and some pedals 1 are arranged as the staircase structure of ladder rising and fix with column 6; The staircase structure of being arranged by pedal 1 is the structure around column 6 ovalisation or square rising.Outer end at each pedal 1 vertically is fixed with guardrail 2, and the upper end of described guardrail 2 is fixed with handrail 4.Also be fixed with fence 3 on the described guardrail 2.The upper end of described column 6 also is provided with flange 7.
In sum, support bar 5 (it be pull bar or the depression bar) vertical columns 6 of the utility model by being fixed in the borehole wall, and with pedal 1, fence 3, handrail 4 or column 6, form the gusseted rock-steady structure.And the gusseted structure that column 6, fence 3, guardrail 2 direct and that support bar 5 is fixed are connected to form should be strengthened design.
The utility model is owing to adopt oval or square rotation ascending manner, so that traditional cat ladder mode has realized the mode of marking time, the inclination angle of the 70-80 degree of being creeped by original ladder has thoroughly become the 30-60 degree, avoided Coal Miners to climb inconvenience that the angle inclined ladder brings has improved the safety factor of escape greatly; Most of processing and installing engineering are all finished on ground, install according to the high down-hole of carrying out of different sections, the down-hole only install need to be by being fixed in the borehole wall brace summer (draw, depression bar) to fix this solar just passable, thoroughly overturned traditional mounting means, greatly shortened installation period.
