Technical Field
The invention discloses a ceiling anti-falling buffer device for an engineering machinery cab, and belongs to the field of cab equipment.
Background
The cab is an important component of the body of a truck and a special automobile and is a place where professional drivers work day and night. The structure of the device is directly related to the safety, the working efficiency and the health of a driver. The cab is generally of a metal thin shell structure, is flexibly connected with the frame, does not bear load, and belongs to a non-bearing type vehicle body.
The existing ceiling anti-falling buffer device for the engineering machinery cab has certain defects, the function of quickly disassembling and assembling a spring is lacked, the spring is generally fixed between a cab shell and a rubber plate and is easily damaged by environmental influence, the effect of buffering falling objects is reduced, and the impact force of the falling objects easily causes the deformation of the cab shell, so that the ceiling anti-falling buffer device for the engineering machinery cab is needed to solve the problems.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide the ceiling anti-falling buffer device for the engineering machinery cab, which solves the problems in the background technology.
In order to achieve the purpose, the invention is realized by the following technical scheme: the utility model provides an engineering machine tool is ceiling buffer of preventing falling object for driver's cabin, includes driver's cabin shell, spring one, telescopic link, rubber slab and dismouting mechanism, a spring lower extreme is laminated mutually with driver's cabin shell upper end, spring one is installed on telescopic link annular side, the telescopic link is installed in driver's cabin shell upper end, the rubber slab is installed in the telescopic link upper end, dismouting mechanism installs at driver's cabin shell front end, the telescopic link lower extreme is installed inside two recesses, dismouting mechanism includes recess one, gag lever post, spring two, draws piece and recess two, recess two is seted up at driver's cabin shell front end, spring two is installed inside two recesses, draw the piece to install at spring one front end and draw the piece front end and extend to driver's cabin shell front side, the gag lever post is installed at drawing the piece rear end, recess one is seted up in driver's cabin shell upper end, the rear end of the limiting rod extends into the first groove and is connected with the telescopic rod.
Further, both ends have all been seted up two T type grooves and two T type inslot portions around the rubber slab and have all installed T type piece, T type piece lower extreme is connected with the telescopic link upper end.
Further, telescopic link, spring one, dismouting mechanism all assemble four, four the telescopic link is evenly installed in the driver's cabin shell upper end, four spring one is evenly installed at the rubber slab lower extreme, four both ends around the driver's cabin shell are installed to dismouting mechanism symmetry.
Furthermore, a limiting hole is processed on the rear wall inside the groove, and a through hole is processed at the lower end of the annular side face of the telescopic rod.
The invention has the beneficial effects that: according to the ceiling anti-falling buffering device for the engineering machinery cab, the first groove, the limiting rod, the second spring, the pulling block and the second groove are added, the first spring is convenient to disassemble, assemble and replace, and the problems that the existing ceiling anti-falling buffering device for the engineering machinery cab has certain defects, the spring is lack of a quick disassembling and assembling function, the spring is generally fixed between an outer shell of the cab and a rubber plate, the spring is easily damaged due to the influence of the environment, the effect of buffering falling objects is reduced, and the outer shell of the cab is easily deformed due to the impact force of the falling objects are solved.
The telescopic rod is convenient to mount due to the addition of the T-shaped groove and the T-shaped block, and the mounting of the limiting rod is convenient due to the addition of the limiting hole and the through hole.
