Abstract

The utility model provides a safe cave crawling ladder. A safe cave opening support is arranged on the top of the crawling ladder; a hinged seat is arranged at a support intersection point of the upper end of the safe cave opening support; a support brace is hinged to the hinged seat; a safety rod is arranged at one side of the crawling ladder; an automatic safety lock catch is arranged on the safety rod. The safe cave crawling ladder has the advantages that the safe cave opening support and the crawling ladder connected with the safe cave opening support are fixed in a cave by use of the support brace on the safe cave opening support, a safety belt is hung on the automatic safety lock catch of the safety rod at one side of the crawling ladder when a worker goes up and down on the crawling ladder, and therefore, the worker can go up and down safely on the crawling ladder. The safe cave crawling ladder is simple in structure, and convenient to set up as well as mount and demount, and consequently, the working efficiency and the safety reliability of constructors can be improved.

Description

A kind of hole safety climbing ladder
Technical field
The utility model relates to a kind of cat ladder, particularly a kind of hole safety climbing ladder.
Background technology
At present, the ladder using in construction is of a great variety, as double ladder, monolateral ladder, rope ladder, hanging ladder etc., to the constructor of the operation of need to climbing to a higher point, has brought facility, has also guaranteed to a certain extent construction safety.Monolateral staircase simplicity of design, use wider, staircase bottom is fixing, top is close to a fulcrum, constructor is staircase work up and down just, double ladder has fixedly double ladder and moving herringbone ladder, fixedly double ladder is that people build instrument temporarily, moving herringbone ladder is that the top of two ladders is connected together with loose-leaf, in the time of mobile, can there is higher flexibility altogether, but that the shortcoming of monolateral staircase and double ladder is the scope of application is narrower, be only suitable for for the effect of ascending a height of not too high place, inapplicable for darker hole.Rope ladder and hanging ladder are mainly used in work high above the ground, and the instrument of climbing is not subject to length restriction, but that they climb difficulty when unsettled is larger, easily rock unstablely, especially stand in construction on rope ladder and hanging ladder and have larger potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of hole safety climbing ladder, and solved existing ladder kind and be not suitable for down compared with deep hole in-cavity construction, and the poor problem of safety.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of hole safety climbing ladder, comprise cat ladder, cat ladder top is provided with aperture emergency support, aperture emergency support is by least six roots of sensation cross bar and three movable frames that montant forms, and on the emergency support of aperture, end support intersection point place is provided with free bearing, and stent support and free bearing are hinged, cat ladder one side is provided with safety pole, and safety pole is provided with secure latch.
Described cross bar is Collapsible structure.
This cat ladder adopts aluminium alloys.
A kind of hole safety climbing ladder that the utility model provides, by the stent support on the emergency support of aperture, fix aperture emergency support and connected cat ladder, during construction, the automatic safety lock that staff hangs over cat ladder one side safety pole by safety belt is buckled, and can guarantee that staff's safety on cat ladder is upper and lower.This apparatus structure is simple, sets up easy accessibility, has improved constructor's operating efficiency and safety reliability.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural front view of the present utility model.
Fig. 2 is structure side view of the present utility model.
Fig. 3 is structure top view of the present utility model.
Fig. 4 is the connection diagram of the utility model stent support 5 and free bearing 7.
In Fig. 1-4: aperture emergency support 1, cat ladder 2, safety pole 3, secure latch 4, stent support 5, support intersection point 6, free bearing 7, cross bar 8, montant 9.
The specific embodiment
As shown in Fig. 1-4, a kind of hole safety climbing ladder, comprise cat ladder 2, cat ladder 2 tops are provided with aperture emergency support 1, aperture emergency support 1 is by least six roots of sensation cross bar 8 and three movable frames that montant 9 forms, and on aperture emergency support 1, end support intersection point 6 places are provided with free bearing 7, and stent support 5 is hinged with free bearing 7, cat ladder 2 one sides are provided with safety pole 3, and safety pole 3 is provided with secure latch 4.
Structure thus, can be by the stent support 5 on aperture emergency support 1 by aperture emergency support 1, and connected cat ladder 2 is fixed in hole, staff can be upper and lower on cat ladder, staff hangs over safety belt on the automatic safe snap close 4 of cat ladder 2 one side safety poles 3, can guarantee staff's upper and lower safety on cat ladder.
Preferably, described cross bar 8 is Collapsible structure.The Collapsible structure of cross bar 8 can, according to using the size of region and hole diameter to regulate aperture emergency support 1, make cat ladder can be applicable to the hole of different pore size.
This cat ladder adopts aluminium alloys or high strength light thin material.It is mobile that cat ladder adopts high strength light thin material to be convenient to cat ladder carrying, and set up and easy accessibility.
When the hole of needs construction is set up passage, first at hole mouth, launch aperture emergency support 1, by regulating cross bar 8 to make aperture emergency support 1 be applicable to hole pore size, runing rest supports 5 makes aperture emergency support 1 be fixed on place, hole, connected cat ladder is also fixed in hole simultaneously, now staff can be upper and lower on cat ladder, staff upper and lower Shi Ke on cat ladder hangs over safety belt with it on the snap close of safety pole, prevent falling from high altitude, make staff's safety on cat ladder upper and lower, when cat ladder length is inadequate, the vertical ladder that can overlap with anti-hook increases length.
