Description
Technical field
The utility model relates to elevators field, does not relate to a kind of can preventing because the elevator traction rope short rope that happens suddenly causes the safety device of car pendant well out of control.
Background technology
The user of elevator people's go off daily, known by people.At present, the principle of work great majority of elevator arrange a towing machine in the top of elevator, the hauling rope be connected with car by this towing machine folding and unfolding and then realize car knee-action.In order to ensure the normal trip of people, improve safety when elevator uses, so need the service work all parts in elevator, device etc. being carried out to periodical maintenance, maintenance, and hauling rope is wherein exactly one of the parts needing time-based maintenance, maintenance.But due to the particularity of its structure of hauling rope and setting position, service personnel is difficult to realize careful service work to it, therefore hauling rope local location there will be the phenomenon of some tiny fracture of wires, disconnected stock.If these phenomenons are not let alone to expand by Timeliness coverage, be easy to cause hauling rope to happen suddenly short rope, finally cause immeasurable elevator fall accident.
Utility model content
The purpose of this utility model is to solve the problems of the technologies described above, and then provides a kind of anti-lift car pendant well device.
The utility model deal with problems adopt technical scheme be:
A kind of anti-lift car pendant well device, it comprises two cross sills be parallel to each other be arranged in same level, above every bar cross sill, be equipped with the entablatrance be parallel to each other with it, between entablatrance, between cross sill and between entablatrance and cross sill, be all fixedly connected with strut bar; On every bar entablatrance, equal correspondence is provided with two brake arms, and one end of every bar brake arm is hinged on entablatrance, and the other end is free end, and is equipped with spring between each free end and corresponding cross sill; Be equipped with fixed pulley A at the two ends place near every bar entablatrance, be equipped with fixed pulley B at the two ends place near every bar cross sill; Lower outhauler is mounted on fixed pulley A, and its one end is fixed on free end, and the other end is fixed on car top; Upper outhauler is mounted on fixed pulley B, and its one end is fixed on free end, and the other end connects hauling rope.
By implementing technique scheme, once the disconnected rope of hauling rope burst, car is caused to do the movement of falling object, now on every bar, the pulling force of outhauler is zero, and add the spring be held between free end and cross sill and will recover elastic deformation, and then the free end promoting brake arm moves, until free end touches elevator madial wall to the direction of elevator madial wall.Elevator madial wall freers and holds friction force upwards and then stop the utility model to continue to fall downwards, meanwhile car continues to move downward and pulls lower outhauler then to freer end pulling force upwards, at this moment because the horizontal throw between two corresponding free ends is greater than the width of elevator inside, so two corresponding brake arms can block just on the madial wall of elevator and then stop car to continue tenesmus simultaneously, finally avoid car directly falls to the generation of elevator shaft bottom accident, thus ensured people's security of the lives and property, improve the safety that elevator uses.
Further, on every bar cross sill, equal correspondence offers two through holes, and the position of corresponding each through hole is equipped with fender pile; One end of this fender pile is fixed on the top of car, and the other end through corresponding through hole, and is provided with the pile cover preventing cross sill from departing from fender pile on this end.
Further, the fender pile between each pile cover and cross sill is set with spring.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model;
Fig. 2 is using state figure of the present utility model.
In figure: 1. hauling rope, 2. entablatrance, 3. cross sill, 4. strut bar, 5. brake arm, 6. fender pile, 7. spring, 8. go up outhauler, 9. descend outhauler, 10. car, 21. fixed pulley A, 31. fixed pulley B, 51. free ends, 61. pile covers.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As shown in Figure 1 and Figure 2, a kind of anti-lift car pendant well device, it mainly comprises two cross sills be parallel to each other 3 be arranged in same level, is equipped with fixed pulley B31 at the two ends place near every bar cross sill 3.Above the every bar cross sill 3 of correspondence, be equipped with the entablatrance 2 be parallel to each other with it, and be equipped with fixed pulley A21 at the two ends place near every bar entablatrance 2, all weld by strut bar 4 between entablatrance 2, between cross sill 3 and between entablatrance 2 with cross sill 3.Every bar entablatrance 2 is equipped with corresponding two brake arms 5 arranged, and one end of this brake arm 5 is hinged on entablatrance 2, and the other end is free end 51.And the horizontal throw between two the corresponding free ends 51 being in every bar entablatrance 2 the same side is all greater than the width of elevator, between each free end 51 and corresponding cross sill 3, be provided with spring 7 simultaneously.On every bar, outhauler 8 is mounted on fixed pulley B31, and its one end is fixed on free end 51, and the other end is connected with hauling rope 1.Under every bar, outhauler 9 is mounted on fixed pulley A21, and its one end is fixed on free end 51, and the other end is fixed on the top of car 10.
In actual use procedure, the disconnected rope once hauling rope 1 happens suddenly, car 10 is caused to do the movement of falling object, now on every bar, the pulling force of outhauler 8 is zero, and add the spring 7 be held between free end 51 and cross sill 3 and will recover elastic deformation, and then the free end 51 promoting brake arm 5 moves, until free end 51 touches elevator madial wall to the direction of elevator madial wall.Elevator madial wall freers end 51 friction force upwards and then stop the utility model to continue to fall downwards, meanwhile car 10 continues to move downward and pulls lower outhauler 9 then to freer end 51 pulling force upwards, at this moment because the horizontal throw between two corresponding free ends 51 is greater than the width of elevator inside, so two corresponding brake arms 5 can simultaneously card just on the madial wall of elevator and then stop car 10 to continue tenesmus, finally avoid car 10 directly falls to the generation of elevator shaft bottom accident, thus ensured people's security of the lives and property, improve the safety that elevator uses.
In order to improve the Joint strenght between the utility model and car 10, on every bar cross sill 3, equal correspondence can also offer two through holes, and the position of corresponding each through hole is equipped with fender pile 6.Wherein, one end of every root guard stake 6 is fixed on the top of car 10, and the other end through corresponding through hole, and is provided with the pile cover 61 preventing cross sill 3 from departing from fender pile 6 on this end.Lower outhauler 9 can be avoided like this to bear separately the gravity of car 10, further increase the safety that the utility model uses.
In order to reach the effect playing damping in brake process, the fender pile 6 between each pile cover 61 and cross sill 3 can also be set with spring 7, even if car 10 slams on the brakes in dropping process like this, also can not produce the sensation of concussion.
Each embodiment above-mentioned all can combine enforcement under the prerequisite that there is not conflict, there is no mutual restriction.
