Detailed description of the invention
Referring to figs. 1 through Fig. 7, the fool proof elevator embodiment of the utility model one band is described further.
The fool proof elevator of a kind of band, comprise car main body 1, described car main body 1 comprises car walls 11, car floor 12, described car floor 12 is hinged with car walls 11, jointed shaft and horizontal direction parallel, jointed shaft is positioned on the sidewall adjacent with the opening of car main body 1, the inside of described car floor 12 is provided with cavity 121, described cavity 121 is through the sidewall of car floor 12 away from jointed shaft, safety device 2 is provided with in described cavity 121, described safety device 2 comprises drive block 21, rotatable driving fluted disc 22, limiting stopper 23, one end of described limiting stopper 23 is fixed with draught line 24, described draught line 24 is through car floor 12, described draught line 24 is fixed with handle 25 away from one end of limiting stopper 23, described handle 25 is positioned at car floor 12 outside the sidewall of car main body 1 opening, sidewall near car main body 1 opening is hidden in below ground when elevator normally runs always, can effectively prevent the passenger when normal operation from encountering handle 25, once occur clamping passenger, because passenger is sandwiched between car floor 12 and the upper roof of hoistway, so now car floor 12 is just above the ground level near the sidewall of car main body 1 opening, passenger just can successfully touch handle 25, the lower wall of described cavity 121 is provided with the driving chute 3 slided for drive block 21, the length direction of described driving chute 3 is parallel with the jointed shaft of car floor 12, described driving fluted disc 22 rotates hinged with the lower wall of cavity 121, described driving fluted disc 22 is positioned at the side of drive block 21 away from the jointed shaft of car floor 12, described drive block 21 is fixed with tooth bar 211 near driving the side of fluted disc 22, described tooth bar 211 coordinates with the flank of tooth driven on fluted disc 22, the lower wall of described cavity 121 is provided with the limit sliding chutes 8 of sliding for limiting stopper 23, the length direction of described limit sliding chutes 8 is vertical with driving the length direction of chute 3, drive link 4 is connected with between described limiting stopper 23 and driving fluted disc 22, one end and the limiting stopper 23 of described drive link 4 are hinged, the other end of described drive link 4 is hinged with the upper surface of driving fluted disc 22, described car walls 11 is provided with the position-limited trough 5 stretched into for limiting stopper 23 near the side of cavity 121 opening, described confinement block can extrude press section 6 to position-limited trough 5 limiting stopper 23 near driving the side of fluted disc 22 to be provided with.
When elevator normally runs, limiting stopper 23 can extrude press section 6 to position-limited trough 5 limiting stopper 23 near driving the side of fluted disc 22 to be provided with, rely on press section 6 that limiting stopper 23 is squeezed in position-limited trough 5, thus whole car floor 12 is fixed, when once occur that passenger is stuck between car floor 12 and the upper roof of hoistway, if when passenger has consciousness, drive block 21 can be driven to move along driving chute 3 by pull handle 25, handle 25 can passenger oneself go to pull more easily, the sidewall of drive block 21 is provided with tooth bar 211, tooth bar 211 coordinates with driving the flank of tooth of fluted disc 22, direct drive drives fluted disc 22 to rotate, drive between fluted disc 22 and limiting stopper 23 and be connected with drive link 4, due to drive link 4 two ends respectively with driving fluted disc 22, limiting stopper 23 is hinged, along with the rotation driving fluted disc 22, drive fluted disc 22 limiting stopper 23 can be driven to move towards the direction away from position-limited trough 5 by drive link 4, when limiting stopper 23 is extracted out completely from position-limited trough 5, car floor 12 loses the effect of limiting stopper 23, will rotate around jointed shaft, now passenger loses the bearing force effect of car floor 12, passenger can not be stuck between car floor 12 and the upper roof of hoistway, passenger just can realize the object of saving oneself, even if passenger self does not have consciousness, the masses around also can be very fast take actv. rescue method, thus redemption life.
The lower end of described car main body 1 is provided with grille guard 7, the edge of described grille guard 7 is fixedly connected with the lower diapire of car main body 1 respectively, after car diapire rotates around jointed shaft, can toward drop by the passenger pressed from both sides, in this process, there will be the situation that passenger falls toward hoistway position unavoidably, be provided with the passenger that grille guard 7 can catch past drop effectively, enhance the safety of whole safety device 2, completely avoid the secondary injury occurred in the process of suing and labouring.
Described press section 6 comprises spring 61, the lower wall of described cavity 121 is fixed with boss 62, described boss 62 is positioned at limiting stopper 23 near the side driving fluted disc 22, one end of described spring 61 is fixedly connected with limiting stopper 23, the other end of described spring 61 is fixedly connected with boss 62, by spring 61, limiting stopper 23 is pushed up in position-limited trough 5, in the process that elevator normally uses, the restriction of boss 62 is subject to by spring 61 one end, the other end of spring 61 tightly will be limited in position-limited trough 5 limiting stopper 23, even if vibrations appear in car diapire, limiting stopper 23 also can not shift out in position-limited trough 5.
Described drive link 4 is less than to driving the distance a at fluted disc 22 center the radius driving fluted disc 22 with driving the hinge-point of fluted disc 22, drive link 4 is greater than 0 with driving the hinge-point of fluted disc 22 to driving the distance a at fluted disc 22 center, because the weight ratio of the car floor 12 of elevator is heavier, when limiting stopper 23 is stuck in position-limited trough 5, limiting stopper 23 to be needed larger power from pull-out in position-limited trough 5, tooth bar 211 drives whole driving fluted disc 22 to rotate, a is less than the radius driving fluted disc 22, because tooth bar 211 drives the distance at fluted disc 22 center to be greater than a with driving the contact point of the flank of tooth of fluted disc 22 distance, labour-saving object can be played in the process of suing and labouring, drive link 4 is greater than 0 with driving the hinge-point of fluted disc 22 to driving the distance a at fluted disc 22 center, the rotational of fluted disc 22 is driven effectively to pull limiting stopper 23 by drive link 4 ground.
In specific implementation process, when occurring that passenger is stuck between car floor 12 and the upper roof of hoistway, the sentient words of passenger passenger oneself can go to pull handle 25, when passenger's imperception, the masses around can go to pull handle 25, when handle 25 is pulled the opening direction of drive block 21 towards car main body 1 by hauling rope, tooth bar 211 on drive block 21 will drive and drive fluted disc 22 to rotate, drive fluted disc 22 will pull drive link 4, the other end of drive link 4 will pull limiting stopper 23 to move, until limiting stopper 23 shifts out completely from position-limited trough 5, now car floor 12 will rotate around hinge-point, the bearing force effect that passenger loses car floor 12 would not be clamped by elevator.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
