Abstract
A kind of scissor platform automatic latch hook safety device is additionally provided with the latch hook mechanism for being locked after scissor-type lifting platform rises to corresponding position to scissor cantilever crane including platform base and platform base hinged scissor cantilever crane on the platform base.The latch hook mechanism includes the latch hook being connected by pin shaft with platform base, is located at clamping portion and the latch hook oil cylinder for pushing latch hook rotation to carry out the locking to scissor cantilever crane with open that scissor cantilever crane bottom end is matched with latch hook.The utility model can be automatically performed the mechanical caging to scissor-type lifting platform, and platform falls caused by preventing because of oil cylinder decompression, play safety protection function, and the latch hook mechanism structure of use is simple, esy to use, safe and reliable and operable automatically.
Description
Technical field
The utility model relates to a kind of automatic latch hook safety devices of scissor platform.
Background technique
Scissor-type lifting platform is widely used high altitude operation special equipment.Since high altitude operation is used to manned or loading
, the safety and stability of platform is to cannot be neglected, current many scissor-type lifting platform high altitude operation be all be self-locking by oil cylinder
Carry out support platform, oil cylinder may because of failure can not support platform, so just very likely result in accident.
Utility model content
To solve the above problems, a kind of scissor platform automatic latch hook safety device is provided, caused by preventing because of oil cylinder decompression
Platform falls, and plays safety protection function.
The purpose of this utility model is achieved in that
A kind of scissor platform automatic latch hook safety device, including platform base 1 and the hinged scissor arms of platform base 1
Frame 2 is additionally provided on the platform base 1 for carrying out after scissor-type lifting platform rises to corresponding position to scissor cantilever crane 2
The latch hook mechanism of locking.
The latch hook mechanism include the latch hook 4 being connected by pin shaft 3 with platform base, be located at 2 bottom end of scissor cantilever crane with
The clamping portion 5 and the latch hook oil cylinder 6 for pushing the rotation of latch hook 4 to carry out the locking to scissor cantilever crane with open that latch hook 4 matches.
The utility model has the beneficial effects that the utility model can be automatically performed the mechanical caging to scissor-type lifting platform,
Platform falls caused by preventing because of oil cylinder decompression, plays safety protection function, the latch hook mechanism structure of use is simple, it is easy to use,
Securely and reliably and operable automatically.
Detailed description of the invention
Fig. 1 is this automatic latch hook mechanism structure locking schematic diagram.
Fig. 2 is that this automatic latch hook mechanism structure opens schematic diagram.
Fig. 3 is that the automatic latch hook mechanism structure is applied in embodiment.
Fig. 4 is that the automatic latch hook mechanism structure applies locking state in embodiment.
Fig. 5 is that the automatic latch hook mechanism structure applies opening state in embodiment.
Wherein 1 be platform base .2 is scissor cantilever crane, and 3 be pin shaft, and 4 be latch hook, and 5 be clamping portion, and 6 be latch hook oil cylinder.
Specific embodiment
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
A kind of scissor platform automatic latch hook safety device, including platform base 1 and the hinged scissor arms of platform base 1
Frame 2 is additionally provided on the platform base 1 for carrying out after scissor-type lifting platform rises to corresponding position to scissor cantilever crane 2
The latch hook mechanism of locking.
The latch hook mechanism include the latch hook 4 being connected by pin shaft 3 with platform base 1, be located at 2 bottom end of scissor cantilever crane with
The clamping portion 5 and the latch hook oil cylinder 6 for pushing the rotation of latch hook 4 to carry out the locking to scissor cantilever crane 2 with open that latch hook 4 matches.
The latch hook 4 can be freely rotated around pin shaft 3, realize it by flexible promotion latch hook 4 rotation of latch hook oil cylinder 6
Locking and opening to scissor cantilever crane 2.
As shown in attached drawing 1~5, scissor-type lifting platform position is a fixed position, and platform stops after rising to extreme higher position,
Latch hook oil cylinder 6, which is started to work, pushes latch hook 4 to turn to locked position, and then declining platform falls on the clamping portion 5 of scissor cantilever crane 2
4 the inside of latch hook, completes locking.When unlock, lift bench first is detached from scissor cantilever crane 2 and latch hook 4, then shrinks latch hook oil
Cylinder 6, falls latch hook, finally declines platform, completes unlock.
Above-described is only preferred embodiments of the present invention, it is noted that for those skilled in the art
For, under the premise of not departing from the utility model general idea, several changes and improvements can also be made, these also should be considered as
The protection scope of the utility model.
