Description
Technical field
The present invention relates to lifting device field, specifically a kind of emergency support of hoistable platform.
Background technique
Hoistable platform is a kind of Multifunctional hoisting loading mechanization equipment, and lifting altitude meter is differed from 1 meter to 30；Hydraulic liter
It drops platform and is suitable for all types of industries enterprise and the production lines such as automobile, container, mold manufacture, and timber is processed, and chemical industry is filling,
It can be equipped with all kinds of table top forms (such as ball roller, turntable, is turned to, tumbled, is flexible), cooperate various control modes (transfer, connection
It is dynamic, explosion-proof), have the characteristics that lifting exactly, frequent starting, loading capacity are big, effectively solves all kinds of liftings in industrial enterprise
Operation difficult point keeps production operation free and relaxed.But hydraulic elevating platform is while be lifted to higher position for object or person,
But also there is the risk fallen in the object being lifted；If the object on hoistable platform falls, not only object is damaged,
It is also possible to the people pounded onto ground or other objects can be directly to works if that contain on hoistable platform is staff
It is damaged as personnel.
Summary of the invention
The present invention provides a kind of emergency support of hoistable platform, can carry out self-locking after platform stopping, avoiding because of elevator
Failure and cause the object that holds on platform to fall and cause accident so that hydraulic elevating platform is more safe and reliable.
The technical solution adopted by the present invention to solve the technical problems is: a kind of emergency support of hoistable platform, including stretches
Contracting sheath and telescopic rod, the flexible sheath include sheath, electromagnet, sliding iron core and reset spring, the cross section of the sheath
In " recessed " shape, sheath is enclosed in outside telescopic rod, and sheath top is connected with hoistable platform；The electromagnet is located at sheath
Lower part；The sliding iron core is in cuboid, slides the V-shaped close to end of iron core and telescopic rod, and slides iron core and be located at electromagnetism
On the left of iron；Described reset spring one end is connected with electromagnet, and the other end is connected with sliding iron core；The cross of the telescopic rod
Section assumes a " convex " shape, the pedestal connection of telescopic rod lower end and hydraulic elevating platform, and telescopic rod and flexible sheath form and cooperate, and stretch
The right side of bar is provided with brake tooth, and sliding iron core can be inserted on brake tooth to prevent flexible sheath from gliding because out of control.
The sheath body length is equal with length of telescopic bar, and telescopic rod is enabled to enter sheath just.
The beneficial effects of the present invention are: can carry out self-locking after platform stopping, avoiding leading to platform because of elevator malfunctions
On the object that holds fall and cause accident so that hydraulic elevating platform is more safe and reliable；Reasonable in design, principle is simple, just
In popularization and use.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.

Specific embodiment
Following further describes the present invention in conjunction with specific drawings.
As shown in Figure 1 and Figure 2, the emergency support of a kind of hoistable platform of the present embodiment, including flexible sheath 1 and telescopic rod 2,
The flexible sheath 1 includes that sheath 11, electromagnet 12, sliding iron core 13 and reset spring 14, the cross section of the sheath 11 are in
" recessed " shape, sheath 11 are enclosed in outside telescopic rod 2, and 11 top of sheath is connected with hoistable platform；The electromagnet 12 is located at
11 lower part of sheath；The sliding iron core 13 is in cuboid, and sliding iron core 13 is V-shaped close to end with telescopic rod 2, and slides
Iron core 13 is located at 12 left side of electromagnet；Described 14 one end of reset spring is connected with electromagnet, the other end and sliding iron core 13
It is connected；The cross section of the telescopic rod 2 assumes a " convex " shape, the pedestal connection of 2 lower end of telescopic rod and hydraulic elevating platform, and telescopic rod
2 form cooperation with flexible sheath 1, and the right side of telescopic rod 2 is provided with brake tooth 21, and sliding iron core 13 can be inserted on brake tooth 21
To prevent flexible sheath 1 from gliding because out of control.
11 length of sheath and 2 equal length of telescopic rod, enables telescopic rod 2 to enter sheath 11 just.
In the use of the present invention, iron core 13 and brake tooth 21 close proximity always are slided under the action of reset spring 14,
So that sliding iron core 13 can be inserted into brake tooth 21 to come so that hoistable platform stops after hoistable platform rises to certain altitude stopping
Only；When hoistable platform needs to decline, operation associated button controls electromagnet 12, so that electromagnet 12 is inhaled iron core 13 is slided
To the right, so that hoistable platform can move down.
The basic principles, main features and advantages of the invention have been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, and the description in above embodiment and specification only illustrates that this is practical
Novel principle, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these
Changes and improvements are both fallen in the scope of protection of present invention.The claimed scope of the invention is by appended claims
And its equivalent thereof.
