SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel safety ladder is used in sinking, this safety ladder can adapt to the mine operation and flee for one's life and use, and extravagant physical power prevents to fall.
The utility model provides a technical scheme that its technical problem adopted is:
a novel safety ladder for sinking a well comprises a safety ladder body vertically arranged in the well; the safety ladder body is horizontally provided with a group of guardrail pairs from top to bottom, each guardrail pair comprises an upper guardrail and a lower guardrail which are arranged in parallel at intervals, the distance between each upper guardrail and each lower guardrail is 600mm, and the distance between each lower guardrail and each upper guardrail of each adjacent guardrail pair is 1000 mm; all the guardrails are in a semi-circular arc shape, and the guardrails can be turned upwards at 102 degrees;
the distance between two adjacent foot boards of the safety ladder body is 400 mm;
the terminal level of emergency staircase body is provided with semicircular bearing platform, and bearing platform can upwards overturn by 90 degrees.
Further, the emergency staircase body from top to bottom divide into in proper order and hangs portion, intermediate junction portion and lower portion of climbing, goes up the portion of hanging and is used for linking to each other with pit shaft suspension rope, and lower portion of climbing contacts with the pit shaft work dish down, and intermediate junction portion contains one to three emergency staircase unit sections.
The utility model has the advantages that:
the safety ladder comprises a safety ladder body, a guardrail is added, the positions of the guardrail and a pedal are optimized, the combination of the guardrail and the pedal can optimize the posture of a person on the safety ladder body, the person can be safely supported by the safety ladder body, the person can conveniently have a rest in the well lifting process to keep physical strength, the person is prevented from slipping and falling, and the safety of the person is ensured.
And the guardrail is upwards overturned and folded when not in use, so that the occupied space is reduced, and the guardrail is flexible to use.
And thirdly, a bearing platform is added at the tail end, the standing area of the last person climbing the safety ladder is increased, and the person is further prevented from slipping and falling.
The safety ladder body is divided into an upper part, a middle part and a lower part, and the middle part can be expanded, so that the length of the safety ladder can be flexibly changed according to the depth of a mine, and the number of people for escaping can be changed.
