Detailed Description

The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As described in fig. 1 to 4: the embodiment discloses a cab overturning safety supporting structure, which comprises a vertical frame 1 and a supporting seat 2, wherein the vertical frame 1 is connected to a frame, the supporting seat 2 comprises an L-shaped bent plate 2-1 and a handle bracket 2-2 connected to the L-shaped bent plate 2-1, the vertical frame 1 comprises a bottom plate 1-1, a first side plate 1-2 and a second side plate 1-3 which are connected to the bottom plate 1-1, in most application scenes, the two side parts are arranged in parallel, and an elastic device for enabling the supporting seat 2 to be attached to the bottom plate 1-1 is further arranged between the vertical frame 1 and the supporting seat 2.

The lower end of the L-shaped bent plate 2-1 is hinged between the first side plate 1-2 and the second side plate 1-3, and the hinging mode can be realized by bolts penetrating through the three. In order to improve the supporting strength, the embodiment also adopts the following optimization measures, firstly, the lower end of the L-shaped bent plate 2-1 is provided with a sleeve 2-3, the sleeve 2-3 is connected with the hinge bolt, the lower end of the L-shaped bent plate 2-1 is welded on the sleeve 2-3 through a flanging 2-6, the flanging 2-6 can wrap the sleeve 2-3, and the length of a welding line is improved; furthermore, in order to improve the strength and rigidity of the supporting seat 2, the upper end of the L-shaped bent plate 2-1 is further provided with a convex rib 2-5, and the convex rib 2-5 is preferably welded at the upper end of the L-shaped bent plate 2-1 to function as a reinforcing rib. In order to avoid the support seat 2 deviating from the cab 7 during the supporting process, the upper surface of the ribs 2-5 of the present embodiment is provided with positioning grooves 2-4 for connecting support blocks of the cab 7.

The elastic device of the embodiment is a tension spring 4, and two ends of the tension spring 4 are respectively connected to the L-shaped bent plate 2-1 and the bottom plate 1-1.

In order to improve the strength of the vertical frame 1, a connecting plate I1-4 and a connecting plate II 1-5 are further arranged between the side plate I1-2 and the side plate II 1-3 in the embodiment.

When needing to support driver's cabin 7, need to operate the manual pump as the power application pole through rocker 3, lift driver's cabin 7 to suitable position, but when rocker 3 does not use, need to place on-vehicle, in order to solve the problem of placing of rocker 3, this embodiment still is equipped with round hole 2-7 at supporting seat 2, when not using rocker 3, inserts rocker 3 to round hole 2-7.

Because the wire rods and pipelines at the bottom of the cab 7 are more, in order to not influence the wiring, the first side plate 1-2 and the second side plate 1-3 of the embodiment are both provided with wire passing holes, and the wire passing rubber rings 5 for playing a role of protection are also arranged in the wire passing holes.

When the support is used, when the cab 7 needs to be supported, the rocker 3 is pulled out to serve as an extension bar to shake the hand pump, the cab 7 is lifted to a proper position, the handle support 2-2 is moved to enable the base of the cab 7 to smoothly pass through the upper end of the support seat 2, the handle support 2-2 is put down after the base is lifted to the top, the support seat 2 is tightly attached to the bottom plate 1-1 through the elasticity of the tension spring 4, the cab 7 falls back at the moment, and the base of the cab 7 just falls on the positioning groove 2-4, so that the cab 7 can be effectively supported, and the injury of a maintainer under the cab 7 due to accidental fall back is prevented.

After the overhaul is finished, the cab 7 is lifted a little by the manual pump, the handle bracket 2-2 is moved to be not in the falling range of the cab 7, then the pressure is relieved to enable the cab 7 to fall back to the frame smoothly, and the rocker 3 penetrates through the round hole 2-7 after the use is finished, so that the use is convenient for reuse, and the loss is avoided.

Compared with the prior art, this embodiment reasonable in design through grudging post 1, supporting seat 2 under the tensile force effect of extension spring 4, forms an ingenious round pin axle construction, can effectively support the driver's cabin 7 that is lifted up when overhauing, has ensured operating personnel's life safety.

The supporting seat 2 is provided with a convex rib 2-5, a sleeve 2-3 and a flanging 2-6 for increasing the strength, and the upper end of the convex rib 2-5 is provided with a positioning groove 2-4 for preventing the base of the cab 7 from being separated from the supporting seat 2. The two wire passing rubber rings 5 can effectively reduce the friction of the pipeline and protect the safe operation of the whole vehicle. This embodiment can also play the effect of accomodating and placing to rocker 3.

The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
