Problems solved by technology

However, due to the harsh working environment of the loader, the cab with this structure is prone to being crushed or deformed by impact
For example, in a mine, once falling objects collapse, the cab will be directly deformed or even flattened; while in mines with bad road conditions, once a rollover occurs, the cab will be deformed or broken by impact, which is harmful to the driver. There is a great threat, so the strength of the cab of this structure is too low, not suitable for use in mines or on mines
In order to increase the strength of the cab, the frame is generally welded inside the thin plate parts of

Example Embodiment

[0018] The present invention will be further described below in conjunction with the drawings.

[0019] Such as figure 1 As shown, a large-tonnage integral cab structure includes a skeleton and sheet metal parts welded to the skeleton. The skeleton is welded by a special-shaped tube and a rectangular tube. The joints of the skeleton are welded with ear plate reinforcement; the entire driving The room is streamlined.

[0020] The framework includes a bottom framework 6, a top framework 5, a rear column 1, a middle and upper column 2, a middle and lower column 3, and a front column 4. The bottom framework 6 and the top framework 5 are both welded with rectangular tubes to form a "well"-shaped structure The front pillar 4 is formed by bending a special-shaped tube; the floor is welded to the bottom frame 6, the front pillar 4 and the rear pillar 1 are welded to the front and rear ends of the bottom frame 6, and the middle and lower pillars 3 are welded to the bottom frame 6 and On th...

Abstract

The invention discloses a large-tonnage integral cab structure. A cab welding assembly is mainly formed by welding a framework and sheet metal parts, and lug plate reinforcing ribs are welded to the connecting positions of the framework. A whole cab is in a streamline type. The cab has certain strength, can be used under coal mines and in mines with bad road conditions, and is beautiful in appearance molding. A framework type rolling preventing structure is adopted, the structure is formed by welding special-shaped pipes and rectangular pipes, a bottom framework body is a reinforced rectangular pipe, and the strength of the cab is guaranteed. A front wall is formed by being stamped by a die, a covering piece is welded to the framework, the sealing performance is good, shock absorption and noise reduction are achieved, welding of the framework and the sheet steel parts is located through process steps of the structures of themselves, and the framework welding assembly structure has the functions of preventing rolling and object falling.

Description

technical field [0001] The invention relates to a driver's cab, in particular to a large-tonnage integrated driver's cab structure, which belongs to the technical field of construction machinery manufacturing. Background technique [0002] At present, as an important part of construction machinery, the loader cab is welded by thin plate parts, and its main function is to provide the driver with a safe and comfortable operating environment. However, due to the harsh working environment of the loader, the cab with this structure is prone to being crushed or deformed by impact. For example, in a mine, once falling objects collapse, the cab will be directly deformed or even flattened; while in mines with bad road conditions, once a rollover occurs, the cab will be deformed or broken by impact, which is harmful to the driver. There is a great threat, so the strength of the cab of this structure is too low, and it is not suitable for use under the mine or on the mine. In order t...
