Viaduct fast rescue escalator

Abstract

The invention discloses a viaduct fast rescue escalator which comprises a stand column and a scaffold component, wherein the stand column is formed by butting multiple sections of sectional bars in a removable manner; ratchets are formed on left and right sides of the sectional bars in the axial direction; the top surfaces of the ratchets are limit surfaces while the bottom surfaces are guide surfaces; the scaffold component is composed of a pair of left and right transverse pipes and a connecting rod; the connecting rod surrounds around the sectional bars; corresponding to the left and right ratchets of the sectional bars, the pair of left and right transverse pipes are fixed at left and right ends of the connecting rod; a regulating handle, a spring and a guide block are arranged in a central hole of each transverse pipe; the outer ends of the regulating handles stretch out of outer ends of the transverse pipes while the inner ends are fixed at the outer ends of the springs; the guide blocks are arranged at the inner ends of the transverse pipes and are fixed with the inner ends of the springs; axial locating structures with at least two gears are arranged between the regulating handles and the transverse pipes; through the axial locating structures, the regulating handles move axially in the transverse pipes and are located, so that the guide blocks stretch out of the inner ends of the transverse pipes and are matched with the ratchets or retract. The escalator disclosed by the invention is simple in structure, convenient to carry, convenient to assemble and low in cost.

Description

technical field [0001] The invention relates to a rapid rescue escalator for a viaduct. Background technique [0002] In the prior art, escalators for rescue at high places such as viaducts are formed by butt joints of multiple sections of pipes. A number of short pipes are threaded butted together to form a long pipe, and a number of parallel horizontal pipes are inserted between the two long pipes by clamping, thereby forming an escalator for high-altitude rescue. [0003] There are many problems in the escalator structure of this structure: [0004] 1. There are many components, which are very heavy, laborious and inconvenient to carry, and are not conducive to rescue work; [0005] 2. There are many components, and the assembly is time-consuming and labor-intensive during use, which is very troublesome and is not conducive to rescue work; [0006] 3. There are many components and high manufacturing costs; [0007] 4. There is no positioning when the escalator is erec...
