Problems solved by technology

[0002] During the operation of the vehicle, there will be accidents where one or two of the wheels fall into the ditch or ridge, or even the accident where the wheel is out of the road. Since the drop between the road surface and the bottom of the ditch or ridge is greater than the height of the jack, it is very difficult in this case. Difficult to rescue
[0003] Especially in the wild, when the driver is driving alone, without the assistance of other people, if the above-mentioned accident occurs, it will be more difficult for the driver to save himself
[0004] At present, in response to the above-mentioned accidents, it is usually rescued by placing stones, sand, and wooden boards under the wheels or using human power to push the vehicle. If the filling is not dense, it is difficult to ensure safety during the self-rescue process of the car, and the expected effect is often not achieved. At present, there is no emergency rescue equipment that can be operated alone in the field to complete the self-rescue of the vehicle

Abstract

The invention discloses a rescue method of hand shaking three-fold-bridge rescue equipment. The rescue method adopts the hand shaking three-fold-bridge rescue equipment, and in particular, relates to load-bearing and quick-supporting emergent rescue equipment with a three-section foldable platform at the top end of a hand shaking jack with an extension rod for vehicle rescue; an extension rod is between the platform and the hydraulic jack; two sets of tooth-shaped projections are in an outer sleeve body of the extension rod; the equipment can realize self rescue through independent operation, largely saves labors, financial resources and the time, supports vehicle wheels through the three-section foldable platform on the jack, and finishes self rescue through adjusting the longitudinal and transverse directions of the three-section foldable platform; and a vehicle can perform longitudinal and transverse translation through the three-section foldable platform to realize the purposes of safe operation, labor saving and convenience for operation, so that the practicability is high.

Description

technical field [0001] The invention relates to a rescue method of a hand-cranked three-fold bridge-type rescue equipment, in particular to a load-bearing fast-supported emergency rescue for a car rescue with a hand-cranked jack with a telescopic rod and a three-section foldable platform at the top equipment. Background technique [0002] During the operation of the vehicle, there will be accidents where one or two of the wheels fall into the ditch or ridge, or even the accident where the wheel is out of the road. Since the drop between the road surface and the bottom of the ditch or ridge is greater than the height of the jack, it is very difficult in this case. Difficult to rescue. [0003] Especially in the wild, when the driver is driving alone, without the assistance of other people, if the above accident occurs, it will be more difficult for the driver to save himself. [0004] At present, in response to the above-mentioned accidents, it is usually rescued by placing...
