Chinese patent CN202483308U discloses a kind of construction elevator cage door lock, comprise seat board, stab diagonally, lay respectively at tooth block and the anti-rotation block of seat board both sides, described seat board has rotating shaft, the diagonal stabbing of institute family has to be engaged in rotating shaft turns hole, the described position, hole that turns makes to be positioned at tooth block side part and is lighter than and is positioned at anti-rotation block side part, described tooth block has tooth mouth towards the side of diagonal stabbing, and described diagonal stabbing has the thorn point snapped in tooth mouth.
Chinese patent CN201560032U discloses a kind of construction elevator bottom cage enclosing door, cage door interlock switch device, comprise near the cage arranged and go along with sb. to guard him frame, cage is provided with cage door, go along with sb. to guard him erection and be equipped with enclosing door, described cage door arranges fixed mount, fixed mount arranges and turns axle, turn axle and fixed mount is hinged, described frame of going along with sb. to guard him arranges position-limited rack, position-limited rack top arranges the connecting lever and corner block that are fixed together, connecting lever and position-limited rack hinged, connecting lever end is fixed on by extension spring goes along with sb. to guard him on frame, and connecting lever top is arranged on turns below axle.Can prevent staff from banging in end cage by mistake and open by mistake the danger of opening and causing with cage door, and turn axle and connecting lever teamwork in the situation of cage whereabouts, automatically open cage door, open the spacing corner block of maintenance door, facilitate workman to pass in and out and portage.
Summary of the invention
The purpose of this utility model is to provide that structure is simple, easy for installation, the good a kind of construction elevator cage door mechanical lock of safety.
The utility model be provided with cage door, counterweight sheave, clamp, cage, to pouring weight and steel rope; Cage door is arranged on cage by pulley guide rails, and steel rope walks around counterweight sheave, and one end of steel rope connects pouring weight, and the other end of steel rope connects cage door, when cage door up pushes away, down falls pouring weight, makes cage door be in opening; When cage door is toward time drop-down, pouring weight is up risen, make cage door be in closure state; Clamp is arranged on cage, and when cage door is in closure state, when the handle of clamp is down pulled, the fore-set on clamp stretches out and withstands bottom pouring weight, and making can not toward declining to pouring weight, and cage door cannot be opened; When up being pulled by the handle of clamp, the fore-set retraction on clamp, can toward declining to pouring weight, and cage door can be opened.
The utility model structure is simple, and easy for installation, the handle active grab when cage will run down is pulled, and cage door just can be made to open, and increases the safety that cage runs, original electric interlocking increases again one safety precaution.
Accompanying drawing explanation
Fig. 1 is the opening schematic diagram of the utility model embodiment.
Fig. 2 is the closure state schematic diagram of the utility model embodiment.
Detailed description of the invention
See Fig. 1 and 2, the utility model embodiment is provided with cage door 1,2 counterweight sheaves 2, clamp 3, cage 4,2 pieces to pouring weight 5 and 2 steel ropes 6.Cage door 1 is arranged on cage 4 by pulley guide rails, and steel rope 6 walks around counterweight sheave 2, and one end connects pouring weight 5, and the other end connects cage door 1, when cage door 1 up pushes away, to pouring weight 5 toward declining, makes cage door 1 be in opening; When cage door 1 is toward time drop-down, to pouring weight 5 toward rising, cage door 1 is made to be in closure state.Active grab 3 is arranged on cage 4, and when cage door 1 is in closure state, when the handle of clamp 3 is down pulled, the fore-set on clamp 3 stretches out and withstands bottom pouring weight 5, makes will, toward declining, cage door 1 cannot be opened to pouring weight 5; When up being pulled by the handle of clamp 3, the fore-set retraction on clamp 3, can toward declining to pouring weight 5, and cage door 1 can be opened.
Structure of the present utility model is simple, easy for installation, when cage will run, the handle of active grab 3 is down pulled, cage door 1 just can be made to open, and increases the safety that cage runs, original electric interlocking increases again one safety precaution.
