Abstract
The utility model relates to a spiral type ladder compartment which comprises a vertical column and a ladder, wherein the vertical column is erected aside a well wall; the ladder is around the vertical column and is in a spiral ascending form; the ladder is composed of a pedal plate, a handrail and a guardrail; the periphery on one side of the ladder is leaned against the well wall; the inner end of the pedal plate is vertically connected with the vertical column; the outer end of the pedal plate close to the well wall is fixed on the well wall through a connecting plate; the connecting plate is clung to the surface of the well wall and is fixed through a fastening piece; and the pedal plate is vertically fixed with the connecting plate. According to the spiral type ladder compartment provided by the utility model, the spiral ladder is fixed by the connecting plate which is fixed with the well wall, so as to form a triangular supporting stable structure; the structure construction of the ladder is fully utilized; and the ladder compartment is more efficiently simplified by adding the vertical column and the connecting plate.
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 spiral solar that personnel withdraw during as the down-hole burst accident.
Background technology
The general vertical solar that coal in China is existing mainly is made up 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 big 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 big, 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 the utility model is to overcome the shortcoming of above-mentioned prior art; A kind of spiral solar is provided; The solar of this kind form of structure has simple and reasonable; And reduced the processing and the installation of a part of member, general relatively vertical solar possesses that material is economized, in light weight, small investment, effect that installation is fast.
The purpose of the utility model solves through following technical scheme:
This spiral solar comprises the stair that stand on the other column of the borehole wall and be around in column curl rising on every side, and said stair are made up of pedal, handrail and guardrail; The periphery of said stair one side leans against on the borehole wall; The inner of said pedal is connected with column is vertical, is fixed on the borehole wall through junction plate near the outer end of the pedal of the borehole wall, and said junction plate is close on the wall of the borehole wall; And fix said pedal and junction plate vertical fixing through securing member.
Above-mentioned securing member is an expansion bolt.
Above-mentioned pedal is that the triangle of horizontal positioned is tabular; The top of set square is that the inner, the base of pedal is the outer end; Be provided with the installing hole that column is vertically passed on its top; Some pedals according to level and angled being enclosed within on the column up and down each other, form spiralling ladder through installing hole.
Above-mentioned junction plate has the radian that adapts with the said borehole wall.
The junction plate fixing rotation ladder of the spiral solar of the utility model through being fixed in the borehole wall forms the gusseted rock-steady structure, and it makes full use of the structure construction of ladder, through increase column, junction plate solar is carried out more efficiently simplification.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the scheme of installation of the utility model pedal 2 and junction plate 5;
Fig. 3 is the C-C sectional view of Fig. 2.
Wherein: 1 is column; 2 is pedal; 3 is guardrail; 4 is handrail; 5 is junction plate; 6 is the borehole wall; 7 is securing member.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1-3, the spiral solar of the utility model comprises column 1 that stands on the borehole wall 6 sides and the stair that are around in column 1 curl rising on every side.Stair are made up of pedal 2, handrail 4 and guardrail 3.The periphery of stair one side leans against on the borehole wall 6; The inner of pedal 2 and 1 vertical connection of column are fixed on the borehole wall 6 through junction plate 5 near the outer end of the pedal 2 of the borehole wall, and junction plate 5 is close on the wall of the borehole wall 6; And fixing through securing member 7, pedal 2 and junction plate 5 vertical fixing.
In the preferred embodiment of the utility model, adopt expansion bolt as securing member 7 fixed connecting plates 5, and junction plate 5 have the radian that adapts with the borehole wall 6.
The triangle that above-mentioned pedal 2 is a horizontal positioned is tabular; The top of set square is that the inner, the base of pedal 2 is the outer end; Be provided with the installing hole that column 1 is vertically passed on its top; Some pedals 2 according to level and angled being enclosed within on the column 1 up and down each other, form spiralling ladder through installing hole.
The utility model support helix formula solar is owing to adopt spiral; Make traditional cat ladder mode realize 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 the colliery underground labour to climb inconvenience that the angle inclined ladder brought has improved the safety factor of escape greatly; Most of processing and installing engineering are all accomplished on ground; Install according to the high down-hole of carrying out of different sections; Install the down-hole only need be just passable through fixing this solar of the junction plate that is fixed in the borehole wall, thoroughly overturned traditional mounting means, shortened installation period greatly.Spiral solar form of fracture can adopt circle or ellipse; Adopt spiral solar to make the useful area in pit shaft of whole solar make full use of; Can the mineshaft diameter of existing design be reduced 0.2-0.5 rice; Also the installation for pipeline etc. provides greater room, thereby has saved the processing of equipments such as a large amount of roadway construction investments and pipeline and install and invest.
