Detailed description of the invention
Attached drawing 1 is the structural schematic diagram of the safety buffer device of the utility model；
Attached drawing 2 is the scheme of installation of the safety buffer device of the utility model.
Wherein: 1, Buffer Unit；11, shell；12, plunger rod；13, spring；14, pressure head；15, pedestal；2, safety switch；
3, push rod；
100, rack.
Specific embodiment
The technical solution of the utility model is further elaborated with reference to the accompanying drawing.
Referring to shown in Fig. 1-2, a kind of safety buffer device for building hoist, building hoist include rack 100,
Lifting be set to rack 100 on cage (not shown), for drive cage go up and down driving mechanism (not shown),
Power switch (not shown) for controlling driving mechanism operation or stopping, safety buffer device are located at below cage,
Including for resisting cage Buffer Unit 1, set on 1 side of Buffer Unit safety switch 2, be connected to 1 side of Buffer Unit
And the push rod 3 extended towards the direction close to safety switch 2, wherein safety switch 2 and power switch are synchronised setting.
Pass through the setting of Buffer Unit 1 and safety switch 2, on the one hand, Buffer Unit 1 can play the tenesmus of cage slow
The effect of punching；On the other hand, safety switch 2 can be associated with the power supply of cutting building hoist, reduce unnecessary energy and disappear
Consumption, eliminates the security risk that building hoist continues to run.
Buffer Unit 1 includes shell 11, along the flexible plunger rod 12 being set in shell 11 in the lifting direction of cage, set
Spring 13 on plunger rod 12, the pressure head 14 set on plunger rod 12 far from 11 one end of shell, wherein 13 both ends of spring are distinguished
It is connected on shell 11 and pressure head 14.Wherein safety switch 2 is set to shell 11 close to one end side of plunger rod 12, push rod 3 one
End is connected to one end side of the plunger rod 12 far from shell 11.
Herein, when building hoist controls failure or brake failure, cage falls down, is added with certain gravity
Speed is pressed in above pressure head 14, and pressure head 14 is run downwardly together with plunger rod 12, spring 13 and push rod 3, the spring energy of spring 13
It is enough that a buffer function is played to the tenesmus of cage.After push rod 3 distally contacts and disconnects safety switch 2, building hoist
The gravity deficiency of itself is to overcome the elastic force of spring 13 to continue to run down, and due to safety switch 2 and power switch phase
Synchronous setting, therefore building hoist stops work, effectively protects equipment.Here, setting by each component relative position
Fixed, total operation stroke of limitation pressure head 14 and plunger rod 12 is not less than 65mm.
In the present embodiment, which is the combination of oil cylinder and spring, and wherein shell 11 is the cylinder body of oil cylinder, column
Stopper rod 12 is the piston rod of oil cylinder.It is provided with hang-up in the control system of building hoist from oil cylinder program is opened, is applying
After work elevator 120s out of service, oil cylinder starting jacks up cage, push rod 3 leaves safety switch 2, and power switch closes upwards
It closes, building hoist continues to run.
Here, Buffer Unit 1 has three groups, and three groups of Buffer Units 1 are at Chinese character pin-shaped arrangement.
The Buffer Unit 1 further includes the pedestal 15 being fixedly arranged on ground, and shell 11 is removably connected on pedestal 15.Shell
It is connected between body 11 and pedestal 15 by bolt.
The course of work of lower the present embodiment is illustrated in detail below: when building hoist controls failure or brake failure,
Cage falls down, is pressed in above pressure head 14 with certain acceleration of gravity, and pressure head 14 is with plunger rod 12, spring 13 and push rod 3
It runs downwardly together, the elastic force of spring 13 can play a buffer function to the tenesmus of cage.Until push rod 3 distally contacts simultaneously
Disconnect safety switch 2 after, the gravity deficiency of building hoist fuselage to continue to run down, and due to safety switch 2 with
Power switch is synchronised setting, and building hoist stops work.After building hoist stops operation 120s, oil cylinder starting will
Cage jacks up upwards, and push rod 3 leaves safety switch 2, power switch closure, and building hoist continues to run.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention.
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
