Description

A kind of mechanically self-locking sliding safety door for cage of vertical shaft hoist cage

Technical field

The utility model relates to a kind of mechanically self-locking sliding safety door for cage of vertical shaft hoist cage.

Background technique

Existing safety door for cage generally uses manual hand manipulation, i.e., before personnel's disengaging, manually by safety door for cage liter It rises and hangs on cage dedicated hook；After personnel's disengaging, safety door for cage is taken from cage dedicated hook manually.This Kind of manual hand manipulation's mode has the following disadvantages, and carries out safety door for cage manually by personnel first and lifts out or toward decentralization It closes, encounters the big door body of tank gate-width, weight, the corrosion of tank curtain door cross bar, deformation card resistance, personnel lift difficulty, and open and close are inconvenient, Large labor intensity.In addition, being lifted if there is external force to catch on safety door for cage, safety door for cage, which does not have, answers in cage decentralization operation Some safety protection function personnel crash into pit shaft danger, therefore vertical lift type safety door for cage is hidden in the presence of greatly safety Suffer from.

Summary of the invention

The purpose of this utility model is to propose a kind of mechanically self-locking sliding safety door for cage of vertical shaft hoist cage, effectively Ground, which is solved, falls well security risk because external force triggers personnel caused by safety door for cage, and safety door for cage card resistance when operation is lifted Difficulty, personnel's limbs stretch out the outer phenomenon of tank.

To achieve the goals above, the technical solution of the utility model is: a kind of vertical shaft hoist cage is mechanically self-locking Slide safety door for cage, upper and lower frame and left and right frame including cage doorway, between upper and lower frame be arranged side by side have it is more A column, multiple columns form the fence of safety door, wherein the upper and lower frame is respectively the upper and lower track of safety door, grid The upper end of column column is connected with pulley, and the lower end of fence post connects sliding sleeve, and pulley is hung on the upper rail of safety door, sliding sleeve It is enclosed on lower railway, by loop chain, laterally successively interval connects multiple fence posts, and one end of loop chain is fixed on cage doorway On left or right frame, the other end of loop chain connects safe doorjamb fence post, in safe doorjamb fence post and opposite Sliding self-locking device is provided on the frame of cage doorway, the sliding self-locking device includes setting in safe doorjamb fence post The ring set for the vertical elevation set, being horizontally disposed on the frame of the cage doorway has a bolt, bolt perpendicular to ring set facade, The axial direction of bolt is provided with a long open-work, is provided with an annulus in long open-work, and annulus passes through the crossbeam that is arranged in long open-work It hangs in long open-work, when closed safe door, pulls out ring set, bolt is inserted into ring set from cage doorway border side, ring set Lower end jacks up annulus, with the relative movement of bolt and ring set, is fallen behind the inside that annulus enters ring set by Safety detent catch for door Firmly；When opening safety door, ring set is inwardly pulled, bolt is removed from ring set, and the lower end of ring set jacks up annulus, with ring set Mobile, annulus is removed from the inside of ring set and is fallen, and safety door is opened.

Scheme is further: the loop chain is three, and three loop chain upper, middle and lower layouts link together fence post, grid The interval of column column is 100mm to 120mm, and folding net metal net is equipped in the fence post of the safety door.

Scheme is further: the ring set is to stand after being bent by the round steel that diameter is 6mm to 8mm with safe doorjamb fence Column welds to be formed, and the diameter of the annulus is not less than 50mm.

Scheme is further: the sliding self-locking device is safety door for cage second safety lock, and the safety door for cage is also It is provided with the first safety lock, the first safety lock includes tapered end and latch post with lockhole, and tapered end is arranged in cage doorway frame On, latch post be arranged in safe doorjamb fence post, when closed safe behind the door, latch post be inserted into tapered end lockhole will be safe Door lock is lived, and when needing to open safety door, the lockhole post-tensioning moving ring sleeve for pulling latch post that latch post is made to be detached from tapered end beats safety door It opens.

The beneficial effect of the utility model compared with prior art is: improving the peace of coal mine shaft lining elevator personnel transport The labor intensity of worker is effectively reduced in Quan Xing, easy to operate；It effectively prevent catching on safety door for cage because of external force, safety door is lifted It rises；Unreliable because vibrating, sliding the safe door latch apparatus of reason when safety door is closed, personnel caused by safety door is opened fall well Casualty accident is avoided due to accident generation and bring life and property loss.

The utility model is described in detail with reference to the accompanying drawings and examples.
