Fixed stop 12 is welded on ladder ontology 11, and block sliding rubber 13 is rectangular upper and opens that there are three through-hole, fixed stops
12 are fastened on fixed stop 12 by that fixation of centre in three block fixing bolts 14, and three steps then pass through fixation
The T-shape shape of block 12 moves in the rectangular sliding slot in the ladder ontology of respective step, welds and reinforces in the middle part of stair body 11
Plate 15, bottom are coated with rubber damping layer 17；By the way that fixed stop 12, block slide rubber 13, block is fixed between three steps
The sliding connection of bolt 14, is connected with two ropes 16 of step length between the first step and third step.
Referring to attached drawing 4,5,6, unlocking executing agency 2 is mainly made of following several parts: triangular key lock 21, cam 22,
Swing rod 23, connecting rod 24, T-shape bar 25, spring 26, mechanical lock head 27, electric switch 28.T-shape bar 25 is by cross bar and front end
T forming head composition.Triangular key lock 21 is universal lock head in elevator industry, is co-axially mounted with cam 22, wherein the axis peace of swing rod 23
The position on the lower side mounted in car top, swing rod 23 and cam 22, connecting rod 24 form lever mechanism, can be with by rotation triangular key lock 21
It drives swing rod 23 and then connecting rod 24 is driven to generate displacement；It is connected at the top of 24 other end of connecting rod and 25 right end of T-shape bar, wherein
25 right end bottom of T-shape bar is connected by spring 26 with car top, and two mechanical lock head 27 and 1 electric switches 28 are installed in left end；
T-shape bar 25 is embedded in the reserved slot of car top, is only capable of sliding left and right, and cam 22 rotates swing rod 23,
Swing rod 23 is subjected to displacement along carriage front-rear direction and passes through connecting rod 24 and haul and is stuck in T-shape bar 25 in car top slot and moved,
And then the actuation of mechanical lock head 27 and electric switch 28 and security window is driven, while spring 26 is with the mobile phase of T-shape bar 25
It should stretch.
Referring to attached drawing 7, security window 3 is mainly made of following several parts: forms 31, mechanical lock 32, electrolock 33.Described 31
Forms are square structure, and two sides are provided with mounting groove and hole axle, and there are two 32 mechanical locks and one 33 are electrical for installation on car top face
Lock forms interlocking structure with 25 T-shape bar left end, 27 mechanical lock head and 28 electric switches.
Referring to attached drawing 8, the top of carriage 4 is main to install following several parts: ladder bracket 41, ladder axis 42, window bracket 43,
Block bolt key 44.Rectangular safe fenestra is provided at the top of shown carriage 4, wherein square hole two sides process two ladder brackets 41,
Wherein the mounting hole of bracket is equipped with ladder axis 42 for fixing security window 3, is wherein provided with house type slot on the inside of square hole and installs
There are two window brackets 43, and when the disconnection with electrolock mechanical in security window 3, security window 3 can slowly be declined by window bracket 43 to be beaten
It opens, two holes is opened at the top of the carriage 4, for installing block bolt key 44,44 shape of block bolt key is not limited to
In a kind of form, can be used cooperatively with 14 fixing bolt of block.
Referring to attached drawing 9-16, when ladder 1 is in folded state, i.e., original state, the security window 3 pass through mechanical and electricity
Air cock interlocks on carriage top, and the swing rod 23 is in plumbness, the mechanically and electrically gas lock of T-shape bar 25 and security window 3
It fastens, spring 26 is in nature non-compressed state.
It when ladder 1 is in extended state, and works in sedan-chair, is rotated in sedan-chair by triangular key, triangular key lock
21 band moving cams 22 are rotated by 90 °, and drive swing rod 23 to be displaced to range, swing rod 23 is subjected to displacement along carriage front-rear direction
And it is hauled by connecting rod 24 and is stuck in T-shape bar 25 in car top slot and is moved, and then drive mechanical lock head 27 and electric switch 28
It is detached from security window, while spring 26 accordingly stretches with the movement of T-shape bar 25, security window 3 is slowly beaten by window bracket 43
It opens, ladder 1 successively opens step according to gravity, since step is relatively heavy, slides rubber using fixed stop 12, block
13, block fixing bolt 14 constitutes slow-descending system, when step slides into sedan-chair described in centre in 3 14 fixing bolts of block
That is mounted in the threaded hole in fixed stop 12, and since block sliding rubber 13 has certain elasticity, block slides rubber
Glue 13 and fixed stop 12 generate frictional force, and then play the downslide of step caused by slowing down gravity, when all steps are all snapped down to
When cab interior bottom, rope 16 extends, and is directly connected in third step 103 from the first step 101, when rescue personnel from
Ladder 1 can grab rope 16 when climbing out of and be rescued.
When ladder 1 is in extended state, and in hoistway work, when personnel complete to climb to car top from cab interior
When, rope 16 is first passed through by step and successively mentions car top from carriage, then first opens up step 103 from step 102 from car top
It opens, leads to after expansion and revolve the block fixing bolt 14 of two sides extremely in the hole of the rectangular sliding slot two sides of ladder ontology 11 completely, according to
It is secondary to be attached the second step 102 and the first step 101 using same method, ladder 1 is overlapped in hoistway after connection,
Forms 31 are being pulled to car top by window bracket 43, by manual toggle swing rod 23, are making it into position as shown in FIG. 6, it will
Mechanical lock head 27 and electric switch 28 on T-shape bar 25 pull in inside car top, when forms 31 are parallel to car top, decontrol swing rod
23, so that carrying out hoistway rescue after mechanical lock head 27 and mechanical lock 32 fasten, electric switch 28 is fastened with electrolock 33.
Therefore, ladder 1 has the function of two-way use: rotation triangular key lock 21 disconnects 3 machinery of security window and electricity in sedan-chair
Air cock and security window 3 are opened, and have 3 steps in ladder 1, between step by fixed stop 12, block slide rubber 13,
Block fixing bolt is attached 14, can slide onto sedan-chair along the square groove in ladder ontology 11 by gravity when extending into sedan-chair
It is interior, carriage is climbed out of for personnel, after personnel evacuate to car top, ladder is packed up either manually or by rope 16, is packed up by window bracket 43
Security window 3, while manual toggle swing rod 23 closes the mechanically and electrically lock of security window 3, then passes sequentially through block bolt key
6 block fixing bolts 14 rotation in each step after death (is prevented step from sliding due to gravity reversal) by spoon 44, to hoistway layer
Sliding ladder uses at door so that car top personnel climb out of hoistway.
And simple lever system, connecting rod 24 are constituted using cam 22, swing rod 23, connecting rod 24 in unlocking executing agency 2
Connection by the conversion of motion of vertical direction be horizontal direction movement, wherein 23 shaft of swing rod apart from cam 22 farther out, distance
Swing rod 23 is close, then can be again in sedan-chair using the rotary force band moving cam 22 of very little using lever principle, and then drives entire system
Dynamic T-shape bar 25 is commanded to move, and the flexible of spring 26 can guarantee that cam 22 is restored to the state of most original, be conducive to whole
A system is resetted.
The above is only the preferred embodiment of the present invention, it is noted that for those skilled in the art,
Without departing from the principles of the invention, several improvements and modifications can also be made, these improvements and modifications also should be regarded as this hair
Bright protection scope.
