There are the first hoistable platform and the second hoistable platform, first hoistable platform and the second hoistable platform are detachably connectable.
The elevating drive mechanism includes motor, drive shaft and driven spindle, on the drive shaft and driven spindle
It is at least fixed with one group of sprocket wheel respectively, the sprocket wheel of drive shaft and the sprocket wheel vertical direction of driven spindle are correspondingly arranged and pass through
Chain connection, described drive shaft one end is additionally provided with the sprocket wheel being connected to the motor by chain.
It further include anti-fall device, the anti-fall device includes hook, sliding rail and hanging seat, the sliding rail and hook vertical array
It is fixed on the inside of the first crane and the second crane, described hanging seat one end is flexibly connected with sliding rail, the other end and the first lifting
Platform or the second hoistable platform are fixedly connected, and the hanging seat connecting plate is equipped with the arc-shaped hole track that the front is high and the back is low, the hole
The load-bearing bolt that can be slided along hole track is equipped in track.
It is respectively opened up on first hoistable platform and the second hoistable platform jagged.
First hoistable platform and the second hoistable platform using connected structure or use locking member connection structure.
Compared with prior art, the beneficial effects of the present invention are:
(1) present invention is equipped with operating platform, and operating platform can be separated into two parts, can use intermediate notch will
Trunk surrounds therebetween, and worker has enough operating spaces to carry out trimming work, tired to rest above, and
It can satisfy multiple workers while the trees of different location trimmed, greatly improve work efficiency；
(2) hoistable platform of the present invention is by lifting device automatic lifting, avoid worker with tool it is continuous frequently on
Under, greatly reduce the workload of worker；
(3) present invention is safe and reliable, has greatly reduced the risk that worker surprisingly falls, and operating platform is also set
Have anti-fall device, ensure that operating platform will not power disappearance after accidental falling.

Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
Embodiment 1:
As shown in Figure 1 and Figure 2, a kind of tree trimming Special lifting ladder, including the first crane 1, the second crane 8, first
Elevating drive mechanism, the lifting and driving of the first crane 1 and the second crane 8 are respectively equipped on crane 1 and the second crane 8
Mechanism is connected separately with the first hoistable platform 4 and the second hoistable platform 9, and the first hoistable platform 4 and the second hoistable platform 9 are separable
Connection.First crane 1 and the second crane 8 can be used alone and can also be used in combination, and flexibly side is used alone
Just, it is suitble to one-man job, working range is applied in combination extensively, more securely and reliably, is suitable for more artificial works.
Embodiment 2:
Elevating drive mechanism includes motor 10, drive shaft 3 and driven spindle 2, the drive shaft 3 and driven spindle 2
Upper to be at least fixed with one group of sprocket wheel 5 respectively, the sprocket wheel 5 of drive shaft 3 and 5 vertical direction of the sprocket wheel correspondence of driven spindle 2 are set
It sets and passes through chain 7 and connect, described 3 one end of drive shaft is additionally provided with the sprocket wheel 5 being connected by chain 7 with motor 10.Lifting passes
The structure of motivation structure is not limited only to above structure form, can also be used other structures similar with the application, such as gear drive,
The structures such as hydraulic lifting.
The other structures of the present embodiment are same as Example 1.
Embodiment 3:
As shown in Figs 1-4, anti-fall device is additionally provided between hoistable platform and crane, anti-fall device includes hook 12, slides
Rail 11 and hanging seat 6,12 vertical arrays of hook are fixed on 8 inside of the first crane 1 and the second crane, and sliding rail 11 is arranged in parallel in
