In the above-mentioned technical solutions, the pressure pin 11 is connect by linear guide with base station 25.
As shown in Figure 8 and Figure 9, bracket 1 is mounted on base station 25, can be slided on base station 25, for uniform load, in base
Stand 25 central symmetry position and meanwhile be arranged two groups of bracket systems.When operating normally on guide rail bracket 27, bracket 1 is in cage 26
Retracted state, locating rod 2 is automatically fallen in the card slot of positioning plate 3 at this time, is avoided cage 26 and is run channel, and the second limit switch
8 effects, controlling equipment at this time allows the control drive system of cage 26 that about 26 cage is driven to run, to prevent cage 26 and support
Frame 1 interferes and causes safety accident.
As shown in Figure 10 and Figure 11, when the suspension building hoist guide rail, 27 preparation supernumerary segments or when tearing section open, first by cage 26
The appropriate location higher than bracket 1 is run to, locating rod 2 is then lifted and leaves 3 card slot of positioning plate, release the mechanical position limitation of bracket 1,
Again to the extrapolated bracket 1 in base station 25, stroke is controlled by position-limited rack 4 when bracket 1 is released, after reaching stroke end, locating rod 2 is certainly
It is dynamic to fall in another card slot of positioning plate 3, and bracket 1 can be forbidden mobile by 18 locking positioning plate 3 of nut, thus real
Accurate mechanical limit, the positioning that existing bracket 1 is released, after bracket 1 releases machinery positioning, the first limit of detection 1 position of bracket is opened
7 effects are closed, cage 26 runs control and taken over by base station 25 at this time, and 25 control system of base station allows to control the driving on cage 26
System, driving cage 26 are run down, when cage 26 goes downwards to the cage that is mounted on bracket 19 position of electric limiting in place,
Third limit switch 9 act on, base station 25 control driving 26 downlink disabler of cage, but can by 25 control system of base station,
The brake for opening drive system on cage 26 allows cage 26 by freely falling on the supporting plate 5 of bracket 1, completes bracket 1
Holding to cage 26, the i.e. weight of cage 26 and its attachment are undertaken by two brackets 1 being fixed on base station 25 completely；Cage
26 by after 1 holding of bracket, and base station 25 can only need that guide rail bracket 27 is driven to move up and down, and reaches the mesh for reducing performance load
's.When base station 25 drives guide rail bracket 27 to move up and down under nominal situation, in order to guarantee that cage 26 can freely be fallen on bracket 1,
The brake of 26 drive system of cage must be in the open state, if at this time because other failures cause brake in on-position
When, when base station 25 drives guide rail bracket 27 to move up, cage 26 is because braking can follow guide rail bracket 27 together on guide rail bracket 27
It moving up, cage 26 and third limit switch 9 are detached from, and after third limit switch 9 disconnects, base station 25 can be cut off and control power supply,
Stop guide rail bracket 27 to move up；When otherwise base station 25 drives guide rail bracket 27 to move down, cage 26 moves downwardly together with guide rail bracket 27
Dynamic, under the action of base station 25 drives, cage 26 can be pressed down against supporting plate 5 and lead to 5 lower part of supporting plate under the effect of external force
Spring 6 compresses, and after certain degree is arrived in 6 compressive deformation of spring, is mounted on the 4th limit switch 10 on bracket 1 and acts on, cut
Disconnected base station 25 controls power supply, stops guide rail bracket 27 and moves down, so that effective protection cage 26 and bracket 1, evade safety wind
Danger.
After base station 25 completes the supernumerary segment of guide rail bracket 27 or subtracts section and guide rail bracket 27 is fixed on base station 25, in cage 26
Before normal use, bracket 1 should be recycled and leave cage operation channel.Recycle bracket 1 when, first pass through base station 25 control cage 26 to
On be moved out bracket system, then unclamp nut 18 and lift the locating rod 2 on bracket 1 and leave 3 card slot of positioning plate, release support
1 mechanical position limitation of frame, bracket 1 are moved into base station 25, are controlled stroke by position-limited rack 4 when bracket 1 is withdrawn, are reached stroke end
Afterwards, bracket 1 leaves cage 26 and runs channel, and locating rod 2 is fallen on automatically in the other card slot of positioning plate 3, and bracket 1 is forbidden to move
It is dynamic, to realize accurate mechanical limit, positioning that bracket 1 is withdrawn, after bracket 1 withdraws machinery positioning, the of detection 1 position of bracket
The effect of two limit switches 8,25 control system power supply of base station is cut off at this time, and base station 25 does not allow to drive cage 26 or guide rail bracket 27
It moving up and down, the recycling operation control of cage 26, the driving operation of cage 26 can only be completed by the control system in cage 26,
I.e. construction elevator cage 26 can operate normally.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the protection scope of the present invention.
