Problems solved by technology

Excavator construction is often carried out on sites with harsh working conditions, such as in tunnels, construction sites, mines, etc. Most of the excavator construction sites are not flat, and the excavator is inexperienced when working on a slope, or the excavator is stressed. Landslides, etc., often cause excavator rollover accidents

Embodiment 1

[0030] like Figure 1-9 As shown, an anti-rollover installation mechanism for a cab includes a protection bolt 4, a fixed main body 11 and a threaded seat 31; 2 and the mounting plate 32 are threadedly connected with the threaded seat 31; the threaded seat 31 is welded on the mounting plate 32; the threaded seat 31 includes a washer 31-2 and a nut 31-1; 4-2 After passing through the washer 31-2, it is threadedly connected with the nut 31-1; the fixed body 11 is welded on the column 9 of the cab 1; when the excavator overturns, the force direction of the protection bolt is along the vertical direction of the column, It can ensure the bearing capacity of the column and avoid the excessive deformation of the beam of the cab, causing the cab to crack and fall off.

[0031] The fixing body 11 includes a fixing block 11-3 and a vertically arranged connecting cylinder 11-4; the fixing block 11-3 is arranged above the connecting cylinder 11-4; the mounting hole 11-2 is along the conn...

Embodiment 2

[0035] like Figure 1-9 As shown, an excavator includes a cab 1 and a vehicle frame 3; the cab 1 is arranged on the mounting plate 32 of the vehicle frame 3; ; The anti-rollover installation mechanism is arranged on the outside of the cab 1; the restriction of dismantling the interior trim and the narrow space at the lower part of the frame is avoided, and the installation and disassembly are very convenient.

Abstract

The invention discloses an anti-rolling mounting mechanism of a cab and an excavator in the field of cab mounting. The anti-rolling mounting mechanism comprises a protective bolt, a fixed main body and a threaded seat, the protection bolt sequentially penetrates through the fixing body, a beam of the cab, a bottom plate of the cab and the mounting plate and then is in threaded connection with the threaded seat. The fixed main body is welded on a stand column of a cab; a limiting plate is mounted on the fixed main body; the limiting plate limits rotation of the protection bolt. When the excavator is overturned, the stress direction of the protection bolts is the vertical direction of the stand column, the bearing capacity of the stand column can be guaranteed, and the situation that a cab cracks and falls off due to excessive deformation of a cross beam of the cab is avoided; the cab mounting position is prevented from loosening and falling off through the limiting plate, and safety accidents caused by connection loosening of the cab and the frame are avoided.

Description

technical field [0001] The invention belongs to the technical field of cab installation, and particularly relates to an anti-rollover installation mechanism of a cab and an excavator. Background technique [0002] Excavators are construction machinery used to excavate soil and ore. According to statistics, more than 60% of earthwork in engineering construction is completed by excavators. In addition, the excavator can also perform various operations such as lifting, logging, crushing, and demolition after replacing the working device. Excavator construction is often done in sites with harsh working conditions, such as in tunnels, construction sites, mines, etc. Most of the excavator construction sites are not flat, and the driver is inexperienced when the excavator is working on the slope, or the excavator is stressed. Landslides, etc., often cause excavator rollover accidents. With the development of the construction machinery industry, users pay more and more attention t...
