Description
Technical field
The utility model belongs in a kind of mine uses cat ladder field, relates in particular in a kind of mine for passing in and out the special ladder of sinking barrel.
Background technology
Mine vertical shaft pit shaft is at present towards super dark, large-scale future development, and pit shaft depth capacity reaches 1350m, and maximum net diameter has reached 10.5m.In order to accelerate speed of shaft sinking, shorten the discharge refuse time, need to increase the volume of hoppet.The volume of hoppet is by original 3m
3, 4m
3, 5m
3increase to 6m
3, 7m
3, 8m
3, ladle body height maximum reaches 4177mm.Go into the well in order to facilitate on personnel, special development sinking barrel special ladder.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of mine work special ladder of the higher sinking barrel of turnover fast of being convenient to.
For solving the problems of the technologies described above, the utility model provides a kind of sinking barrel special ladder, described special ladder comprises outside staircase and manhole ladder, described outside staircase comprises the cat ladder frame of the rectangular trapezoidal shape that two left and right are oppositely arranged, between described two cat ladder framves, be connected with horizontal pedal, described cat ladder top of the trellis is provided with platform, and described manhole ladder is arranged on the cat ladder frame lateral surface of outside staircase front portion, described manhole ladder comprises telescopic three sections, and the cat ladder frame of described manhole ladder and outside staircase is hinged.
Preferably, the total length that described manhole ladder extends is 2.5 meters.
Preferably, the cat ladder frame bottom of described outside staircase is provided with universal wheel, on described universal wheel, is provided with service brake.
Preferably, in described outside staircase, be provided with guardrail.
The sinking barrel special ladder of technical solutions of the utility model, conventional cat ladder of the prior art is transformed, first widen pedal, when being convenient to mine work and going into the well, hook personnel steady ladder on one side, can carry out down-hole operation on one side, in cat ladder front portion, manhole ladder is set, when work, manhole ladder is placed in to sinking barrel portion, produce manhole ladder, convenient operation personnel enter sinking barrel inside by manhole ladder, also can carry out this operation is convenient to mine personnel and goes out sinking barrel simultaneously, manhole ladder is arranged at outside staircase front portion hinged, in the time not needing manhole ladder work, manhole ladder is pushed away to retractor state, make manhole ladder become as a whole with outside staircase, be convenient to the movement of cat ladder, save time, raise the efficiency.
The length that the manhole ladder of the sinking barrel special ladder of technical solutions of the utility model extends is completely 2.5 meters, this length draws through calculating and testing, the maximum height 4177mm of this length and sinking barrel of the prior art adapts, and can meet mine work and pass in and out all sinking barrels.
The sinking barrel special ladder of technical solutions of the utility model, full ladder forms with Plate Welding, increases the weight of ladder body, makes in the time being subject to force unbalance, there will not be the phenomenon of toppling over.
Adopt the beneficial effect of technique scheme to be: sinking barrel special ladder is simple in structure, easy to use, and floor space is little, can meet mine work in prior art and pass in and out all sinking barrels.
