Description

Rollover prevention cab frame

Technical Field

The utility model belongs to the engineering machine tool field, specifically speaking especially relates to a prevent rolling over driver's cabin frame.

Background

In order to meet the requirements of disassembling and assembling the cab of some loaders during transportation, the split type cab becomes an industry design trend. As shown in fig. 1, the conventional split loader cab is divided into a conventional type and a rollover prevention type, and the conventional split loader cab is generally constructed by assembling upper and lower frames with fastening bolts, washers, etc. The upper frame and the lower frame of the split cab frame are directly fixed together through the bolt washers, the structure can realize the anti-rolling performance of the whole cab with small tonnage, but the structure cannot meet the anti-rolling requirement of higher level due to high requirements on required loading force and energy when the cab with large tonnage is used. Meanwhile, the upper frame and the lower frame are fixed together through the lower plate, so that a larger height difference is formed between the inner floor and the outer floor of the frame, and the universal design is not convenient when the inner floor of the cab is arranged.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: the anti-rolling cab frame has the advantages that the defects of the prior art are overcome, the anti-rolling cab frame is of an embedded structure, the upper frame and the lower frame are provided with lateral limiting functions after being combined, vertical and lateral fixing is matched, the overall strength of the cab frame is guaranteed, and the use requirements of the anti-rolling cab frame of a large-tonnage machine type are met.

The anti-rolling cab frame comprises an upper frame and a lower frame, wherein a mounting seat is arranged at the bottom of the upper frame, a mounting groove is formed in the periphery of the lower frame matched with the upper frame, the upper frame is embedded into the mounting groove of the lower frame through the mounting seat, and the bottom of the mounting groove is fixedly connected with the lower frame through a fastening piece.

Preferably, the left side, the right side and the rear side of the bottom of the upper frame are respectively provided with a mounting seat, the mounting seats are rectangular tubes, the peripheries of the left side, the right side and the rear side of the lower frame are respectively provided with a mounting groove, the bottom and the inner side in the mounting groove are respectively provided with a mounting plate fixedly connected, and the mounting seats are matched with the mounting plates.

Preferably, the mounting plate on the inner side of the mounting groove is fixedly connected with the mounting seat through a fastener.

Preferably, the lower frame is provided with a table plate, and the table plate is almost flush with the upper plane of the mounting seat.

Preferably, a round wire seat is arranged inside the mounting seat and matched with the fastener.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model adopts a split cab frame structure, wherein the bottom of the upper frame is additionally provided with a mounting seat, the periphery of the upper part of the lower frame sinks, the mounting groove is additionally provided, and the cab frame integrally has certain self-locking capability through the embedding of the upper frame of a concave structure and the lower frame of a convex structure;

2. the upper frame and the lower frame are respectively fixed by bolts in the vertical direction and the lateral direction, and the anti-rolling structure of the whole cab frame realizes the maximum strength, so that the anti-rolling performance requirement of a large-tonnage machine type is met;

3. the utility model discloses an embedded structure, under the prerequisite that does not increase the inside and outside additional strengthening of frame, realized more tonnage anti-roll performance requirement.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings and embodiments:

the first embodiment is as follows: as shown in fig. 2 to 4, the rollover prevention cab frame comprises an upper frame 1 and a lower frame 6, wherein a mounting seat 2 is arranged at the bottom of the upper frame 1, a mounting groove 3 is arranged at the periphery of the lower frame 6, which is matched with the upper frame 1, the upper frame 1 is embedded into the mounting groove 3 of the lower frame 6 through the mounting seat 2, and the bottom of the mounting groove 3 is fixedly connected with the lower frame 6 through a fastener; the left side, the right side and the rear side of the bottom of the upper frame 1 are respectively provided with a mounting seat 2, the mounting seats 2 are rectangular tubes, the peripheries of the left side, the right side and the rear side of the lower frame 6 are respectively provided with a mounting groove 3, the bottom and the inner side in the mounting groove 3 are respectively provided with a mounting plate 8 which is fixedly connected, and the mounting seats 2 are matched with the mounting plates 8.

In the embodiment, the upper frame 1 and the lower frame 6 are only fixed by bolts in the vertical direction, and are mainly suitable for the anti-rolling performance of a small-tonnage cab.

Example two: the mounting plate 8 on the inner side of the mounting groove 3 is fixedly connected with the mounting seat 2 through a fastener; the lower frame 6 is provided with a table plate 7, and the table plate 7 is almost flush with the upper plane of the mounting seat 2. The rest is the same as the first embodiment.

In the embodiment, the upper frame 1 and the lower frame 6 are respectively fixed by bolts in the vertical direction and the lateral direction, so that the anti-rolling structure of the whole cab frame realizes the maximum strength, and the anti-rolling performance requirement of a large-tonnage machine type is met.
