As a preference of the present invention, the buffering pneumatic cushion when elevator works normally inside gassy, and bottommost is high
High 0.3 ~ the 0.5m in bottom when spending more fully extended than the hydraulic buffer cylinder.
The hydraulic buffer cylinder first contacts to earth buffering as a result, is retracted to and stretches out bottom surface and flush with the buffering pneumatic cushion bottommost
When simultaneous buffering again.
As a preference of the present invention, the secondary seal boss fills in the transit joint lower communication hole depth greater than institute
It states primary seal boss and fills in communicating passage lower part bore depth.
As a result, the hydraulic buffer cylinder contact to earth retraction buffering when hydraulic oil be depressed into the transit joint, the rubber stopper
The secondary seal projection section be pushed out the intercommunicating pore by hydraulic oil thrust, when the secondary seal boss is completely de-
Communicating passage lower part inner hole is completely disengaged from primary seal boss described in the intercommunicating pore, i.e., the described rubber stopper is completely de-
It falls, the gas in the buffering pneumatic cushion is just able to enter in the safety air cushion.
As a preference of the present invention, when the hydraulic buffer cylinder stroke is compressed into 80% ~ 95%, gas in the safety air cushion
Body is full of.
As a result, the hydraulic buffer cylinder stroke on earth when the safety air cushion fill with gas, so as to sufficiently protect
Protect the personnel in carriage.
As a preference of the present invention, being covered with protective pad, the protective pad on the safety air cushion of the cage bottom
For soft material.
It will not directly be trampled on the safety air cushion when people walks in the carriage as a result, the safety will not be made
Air cushion friction and it is damaged.
As a preference of the present invention, fitting is installed on the carriage bottom surface, two sides when the safety air cushion unaerated
And medial surface, and side mounting height is greater than 1m.
In conclusion the invention has the following advantages:
Safety air cushion is arranged in elevator with buffer unit of the invention in carriage, outside carriage be arranged hydraulic buffer cylinder and
Cause safety air cushion work while buffering pneumatic cushion, hydraulic buffer cylinder and buffering pneumatic cushion work, can not only be touched in used during elevator falling
Play the role of buffering when bottom, while the personnel in carriage are protected the injury that is not hit, the inside and outside collaboration of carriage by safety air cushion
Protecting effect is more preferable.
Detailed description of the invention

Specific embodiment
Below in conjunction with attached drawing, by specific embodiment, the invention will be further described.
As shown in Figure 1, Figure 2, Fig. 3, Fig. 4, a kind of elevator with buffer unit, including carriage 1 are equipped with substitute in carriage 1
Pad 2, safety air cushion 2 are located at below the bottom surface and side of carriage 1；
1 outside lower section of carriage is equipped with hydraulic buffer cylinder 3 and buffering pneumatic cushion 4, and hydraulic buffer cylinder 3 is vertically arranged at carriage 1
At bottom margin, buffering pneumatic cushion 4 is set to 1 bottom centre of carriage；
It is provided with communicating passage 5 between safety air cushion 2 and buffering pneumatic cushion 4, is equipped with transit joint 51, mistake in communicating passage 5
51 lower end of connector is crossed equipped with intercommunicating pore 511, side is equipped with the interface being connected to intercommunicating pore 511；
Hydraulic buffer cylinder 3 connect one end with carriage 1 equipped with oil pipe 31, and oil pipe 31 is connected to 51 side of transit joint and connects
Mouthful；
5 lower end of communicating passage is equipped with rubber stopper 52, and rubber stopper 52 includes primary seal boss 521 and secondary seal boss
522, primary seal boss 521 fills in 5 lower part inner hole of communicating passage, and secondary seal boss 522 fills in 51 lower part of transit joint company
Through-hole 511.
As shown in Figure 1, Figure 2, hydraulic buffer cylinder 3 is multi-stage oil cylinder, fully extended state is in when elevator works normally, and internal
Full of hydraulic oil.
As shown in Figure 1, Figure 2,3 stroke length of hydraulic buffer cylinder is greater than 1.5m.
3 trip segment of hydraulic buffer cylinder is for buffering carriage, and the longer effect of length is better, in order to guarantee buffering effect
Stroke length need to be greater than 1.5m.
Such as Fig. 1, buffering pneumatic cushion 4 when elevator works normally inside gassy, and bottommost height is than hydraulic buffer cylinder 3
High 0.3 ~ the 0.5m in bottom when fully extended.
Hydraulic buffer cylinder 3 first contacts to earth buffering as a result, is retracted to and stretches out bottom surface and flush Shi Zaitong with 4 bottommost of buffering pneumatic cushion
When buffer.
Such as Fig. 4, secondary seal boss 522 fills in 51 lower communication hole of transit joint, 511 depth greater than primary seal boss
521 fill in 5 lower part bore depth of communicating passage.
As a result, hydraulic buffer cylinder 3 contact to earth retraction buffering when hydraulic oil be depressed into transit joint 51, the second level of rubber stopper 52 is close
It seals 522 part of boss and is pushed out intercommunicating pore 511 by hydraulic oil thrust, when secondary seal boss 522 completely disengages intercommunicating pore 511
Primary seal boss 521 has completely disengaged 5 lower part inner hole of communicating passage, i.e. rubber stopper 52 is completely fallen off, in buffering pneumatic cushion 4
Gas is just able to enter in safety air cushion 2.
When 3 stroke of hydraulic buffer cylinder is compressed into 80% ~ 95%, gas is full of in safety air cushion 2.
As a result, 3 stroke of hydraulic buffer cylinder on earth when safety air cushion 2 fill with gas, so as to the carriage that adequately protects
Interior personnel.
As shown in Figure 1, Figure 2, protective pad 6 is covered on the safety air cushion 2 of 1 bottom of carriage, protective pad 6 is soft material.
Will not directly be trampled on safety air cushion 2 when people walks in carriage 1 as a result, will not make safety air cushion 2 rub and
It is damaged.
As shown in Figure 1, Figure 2, fitting is installed on 1 bottom surface of carriage, two sides and medial surface, and side when 2 unaerated of safety air cushion
Face mounting height is greater than 1m.
Embodiment described above is only that preferred embodiments of the present invention will be described, not to design of the invention
It is defined with range.Without departing from the design concept of the invention, ordinary people in the field is to technical side of the invention
The all variations and modifications that case is made, should all drop into protection scope of the present invention, the claimed technology contents of the present invention,
Through being all described in the claims.
