When the surface of hoistable platform 2, arc hook 44 catches on 5 side of limited block.Arc hook 44 catches on 5 side of limited block
Afterwards, due to the blocking by limited block 5, upper lifting platform 1 can not direction guiding rail 16 free end it is mobile, and due to locating part
Blocking, upper lifting platform 1 can not skid off guide rail 16 to the direction of free end far from guide rail 16, therefore, by from
Limiting device 4 can fix the position of upper lifting platform 1.
In the present embodiment, the surrounding edge of the loading plate 14 of upper lifting platform 1 is equipped with anti-fall sidebar 18.Anti-fall sidebar
Anti-skidding felt 181 is equipped in 18, anti-skidding felt 181 can be fixed using high-strength double-face glue.The coefficient of friction of anti-skidding felt 181 is very
Greatly, even if the oil droplet of switch operating mechanism falls in anti-skidding felt 181, it still can guarantee that switch operating mechanism does not slide steadily.
For the ease of staff's operation, the side of the pedestal 11 of lower layer's hoistable platform 2 is equipped with push rod 19.Hand-hydraulic cylinder
12 with being arranged with pressurized handgrip 121 and pressure release handle 122, by pressurized handgrip 121 can to 12 manual pressure of hand-hydraulic cylinder,
It can be to the manual pressure release of hand-hydraulic cylinder 12 by pressure release handle 122.Pressurized handgrip 121 and pressure release handle 122 can pass through glue
Pipe is connect with hand-hydraulic cylinder 12.The pressurized handgrip 121 and pressure release handle 122 of lower layer's hoistable platform 2 can integrate in push rod 19
On, or elsewhere.
By the above-mentioned means, the mobile lifting platform for operation mechanism for high voltage switch maintenance of the utility model can expire
Dress is dismantled and returned to the operation mechanism for high voltage switch of sufficient different height, has a good versatility, and by from limiting device, anti-
The risks such as pendant sidebar, anti-skidding felt can be injured by a crashing object to avoid personnel, pulled muscle, equipment damage, can be improved safety.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other related technical areas are also included in the patent protection scope of the utility model.
