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 device that can be operated alone in the field to complete the self-rescue of the vehicle

example 1

[0058] Example 1: if Figure 1 to Figure 18 A hand-cranked three-fold bridge-type rescue equipment includes a scissor-type hand jack J, a platform 3, a left telescopic plate 3-21, a right telescopic plate 3-22, a telescopic rod A, and a bottom plate D,

[0059] The support top at the top of the scissors jack J is connected to the lower part of the middle section of the platform 3;

[0060] The scissor hand jack J and the platform 3 can rotate horizontally;

[0061] A bottom plate D is connected to the bottom of the scissor hand jack J;

[0062] The area of ​​the bottom plate D is greater than the projected area of ​​the platform 3;

[0063] There is a telescopic rod A between the platform 3 and the scissor hand jack J;

[0064] The bottom of the telescopic rod A is connected with the support top at the top of the scissor hand jack J;

[0065] The middle section of the platform 3 is horizontally connected with the top of the telescopic rod A;

[0066] The platform 3 and the ...

example 2

[0080] Example 2: According to a hand-cranked three-fold bridge-type rescue device described in Example 1, the upper section inside the outer tube cavity 1-2 has evenly distributed parallel internal tooth-shaped protrusions 1-1, The lower part of the inner tooth-shaped protrusion 1-1 is a hollow straight pipe, or the inner tooth-shaped protrusion 1-1 is uniformly distributed in parallel throughout the outer casing cavity 1-2.

example 3

[0081] Example 3: a hand-cranked three-fold bridge-type rescue equipment according to Example 1 or 2,

[0082] There is a positioning groove 7 in the middle of the "outer teeth";

[0083] The outer sleeve body 1 also includes a safety buckle, and the safety buckle is installed on the side of the upper section of the outer sleeve body 1;

[0084] The safety clasp lock also includes a positioning thimble 6-1 and an elastic body 6. The elastic body 6 inside the safety clasp lock bounces the thimble 6-1 inward, and the inner tooth shape protrudes 1-1 and the outer tooth shape protrudes When 2-1 rotates and coincides, the thimble 6-1 snaps into the positioning groove 7;

[0085] In the case that a single wheel of the vehicle falls into a shallow pit and cannot be moved, first put the bottom plate D into the bottom of the pit to fix it, and then place the Figure 4-6 The shown telescopic pole A and platform 3 are installed on the scissor hand jack J, then the left telescopic plate...

Abstract

The invention relates to hand-cranked triple-foldable bridge type rescue equipment, in particular to an emergency rescue device which is provided with a telescopic rod, is used for automobile rescue and can be used for bearing and quickly supporting, wherein three sections of foldable platforms are arranged at the top end of a hand-cranked jack. The telescopic rod is arranged between the platforms and a hydraulic jack; and four groups of toothed protrusions are arranged inside an outer casing pipe body of the telescopic rod. According to the equipment, self-rescue can be realized by independent operation, so that labor force, financial resources and time are greatly saved; according to the equipment, wheels of an automobile are supported by the three sections of foldable platforms on the jack; the self-rescue is finished by adjusting longitudinal and transverse directions of the three sections of foldable platforms; and the automobile can longitudinally translate and transversely translate through the three sections of foldable platforms, so that safety and labor conservation in operation are realized, the aim of facilitating the operation is achieved, and high practicality is realized.

Description

technical field [0001] The invention relates to a hand-cranked three-fold bridge-type rescue equipment, in particular to a load-bearing fast-support emergency rescue device for automobile rescue with a hand-cranked jack with a telescopic rod and a three-stage foldable platform at the top. 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.
