Embodiment
Illustrate the present invention below in conjunction with the accompanying drawings.
As shown in accompanying drawing 1-2, it is of the present invention it is a kind of with fall arrest locking hydraulic elevating platform, comprising leading truck 1,
Oil cylinder dolly 2, fixed mount 3 and lifting platform 4；The left and right sides of the leading truck 1 be provided with guide rail and it is multiple vertically
Evenly distributed clamping block 5, two vertical oil cylinders 6 is additionally provided with leading truck 1, two oil cylinders 6 are located at front and rear sides respectively；
The fixed mount 3 is arranged on the middle part of leading truck 1, and oil cylinder dolly 2 is arranged on the upside of fixed mount 3, the bottom of oil cylinder dolly 2 with
The telescopic end connection of oil cylinder 6, the guide rail of oil cylinder dolly 2 and lifting platform 4 with leading truck 1 are slidably matched；The oil cylinder dolly 2
Sprocket wheel 7 is additionally provided with the corner of bottom, oil cylinder dolly 2 is connected to lifting platform 4 by 4 chain interoperations, one end of chain
On lifting platform 4, the other end is connected on fixed mount 3 around sprocket wheel 7；Also set up on the corner of the sidepiece lower end of the lifting platform 4
