Common solution method is to use mechanical limiter of speed, i.e., drives governor sheave by the steel wire being attached thereto when car is walked
Rotation, when speed is higher than threshold values, the centrifuge arm touching safety switch on pulley, the signal that falls is provided, it is this using machinery limit
The method of fast device needs the mechanical mechanisms such as steel wire, pulley, centrifuge arm, spring, and steel wire length is proportional to story height, it is necessary to consume
Material is more, while there is also the problem of numerous and diverse is installed, causes the problems such as cost is high, construction is difficult, and in current elevator system
In system, elevator keeps stopping at the state of some position, be by the band-type brake frictional force of traction machine prevent motor rotation and reality
Existing, once band-type brake failure car or counterweight will fall along hoistway under gravity.Such case once occurs in elevator
During level position enabling disengaging passenger, caused personal injury accident is very serious.And many elevator bottoms do not have
Fall protection equipment, reason are that existing fall protection equipment is complicated and cost is high, poor durability, it is difficult to are safeguarded.
A kind of therefore, it is proposed that elevator bottom protector.
Utility model content
Main purpose of the present utility model is to provide a kind of elevator bottom protector, by provided with cushion, preventing
Only drop casualties, while carries out preliminary buffering and damping to the cage that high speed falls.By provided with hydraulic press, working as electricity
Terraced case is out of control when rapidly dropping, and cage is pressed onto on cushion, due to Action of Gravity Field, may proceed to push so that and hydraulic press compresses,
Hydraulic press is not in bounce-back and seismism in compression, so as to enter row buffering and damping to cage, avoids secondary vibrations,
Ensure that personal safety so that elevator case safety and steady fall earthward.By provided with pouring weight, bearing plate and neck, working as electricity
Elevator car can be pressed onto bearing plate when rapidly dropping, and due to Action of Gravity Field so that pouring weight moves upwards, the gravity of elevator tenesmus is changed
On the active force moved upwards to pouring weight, the lapse rate of cage is effectively reduced, effectively can be solved in background technology
The problem of.
To achieve the above object, the technical scheme that the utility model is taken is：
A kind of elevator bottom protector, including bottom plate, cushion, hydraulic press and chute, the bottom plate upper end are provided with
Chute, the chute side are provided with pouring weight, and the pouring weight side is provided with fixture block, lock key, the lock are provided among the pouring weight
Only key side is provided with spring, and the chute is fixedly connected with crossbeam, and the crossbeam side is fixedly connected with pulley, on the pouring weight
End is provided with steel wire rope, and the steel wire rope is buckled with pouring weight by hanger to be fixedly connected, and bearing plate is provided with above the bottom plate, described to hold
Dividing plate is provided with above weight plate, hydraulic press is provided between the bearing plate and dividing plate, cushion is provided with above the dividing plate.
Further, the pouring weight is connected with bearing plate by steel wire rope.
Further, the bearing plate is bearing plate made of steel material.
Further, the dividing plate is dividing plate made of aluminum alloy material.
Further, the cushion is cushion made of hair foam.
Further, the chute top is provided with neck.
Compared with prior art, the utility model has the advantages that：
1st, by provided with cushion, preventing the casualties that drops, while preliminary delay is carried out to the cage that high speed falls
Punching and damping.
2nd, by the way that provided with hydraulic press, when elevator case is out of control rapidly to drop, cage is pressed onto on cushion, because gravity is made
With may proceed to push so that hydraulic press compresses, and hydraulic press is not in bounce-back and seismism in compression, so as to elevator
Row buffering and damping are entered in railway carriage or compartment, avoid secondary vibrations, ensure that personal safety so that elevator case safety and steady fall earthward.
3rd, by that provided with pouring weight, bearing plate and neck, bearing plate can be pressed onto when cage rapidly drops, because gravity is made
With causing pouring weight to move upwards, the gravity that elevator drops is transformed on the active force that pouring weight moves upwards, effectively reduced
The lapse rate of cage.
