Description

Technical Field

[0001] This utility model relates to a protective structure for the cab of a loader, belonging to the field of engineering machinery technology. Background Technology

[0002] Currently, rollover protection cabs have become one of the basic requirements for cab designation. The built-in rollover protection frame structure of large-tonnage loaders is relatively weak and no longer meets the requirements of large-tonnage products. At the same time, the rollover protection frame must be designed to prevent its flexible deformation from intruding into the DLV area of ​​the cab, in order to protect the driver. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides an external anti-rollover frame with high structural strength, and its flexible deformation will not damage the cab, thus protecting the driver after the whole machine rolls over.

[0004] This utility model is achieved through the following technical solution: a protective structure for a loader cab, comprising a base, a left column, a right column, a top cover plate, and a rear upper crossbeam. The top cover plate is connected to the rear upper crossbeam, which is connected to the top of the left and right columns. The bottom of the left and right columns is connected to the base. Bolt mounting holes are arranged around the perimeter of the base, and the base is connected to the vehicle frame by bolts passing through the bolt mounting holes. The left and right columns are frame structures used to support the cab protective structure.

[0005] The rear upper crossbeam is also connected to a side support beam, and the other end of the side support beam is connected to a front upper crossbeam. The side support beam, the front upper crossbeam, and the rear upper crossbeam are fixedly connected to the top cover plate to form an integral rigid structure.

[0006] A reinforcing beam is provided between the side support beam and the front upper crossbeam and the rear upper crossbeam.

[0007] The number of reinforcing beams is 6, which increases the torsional resistance of the cab protection structure.

[0008] The top of the top cover plate is also provided with a rearview mirror bracket mounting seat. There are two rearview mirror bracket mounting seats, which are arranged on the left and right sides of the top cover plate for installing rearview mirror brackets.

[0009] The top of the top cover plate is also provided with an accessory bracket, and there are 4 accessory brackets. The accessory brackets are arranged on the top of the top cover plate for installing electrical components.

[0010] The top cover plate is also provided with two lifting seats, which are arranged on the left and right sides of the top cover plate and fixedly connected to the top cover plate, serving as lifting points for the cab protection structure.

[0011] The top cover is an integral U-shaped structure, which serves to protect the cab from falling objects.

[0012] The beneficial effects of this utility model are: it provides a high-strength external anti-rollover protection structure for the cab of a large-tonnage loader, which protects the driver; the overall welded structure is lightweight, reducing the overall weight of the machine and thus reducing the vehicle's fuel consumption.
