Abstract
The utility model relates to a six-column anti-overturn protection device for a crawler dozer, which comprises a side beam, a front upright post, a front bracket, a cross beam, a left rear upright post, a left bracket soldering part, a left bend plate soldering part, a right bend plate soldering part, a right bracket soldering part, a right rear upright post, an anti-overturn frame rear protective net, a right forebeam, a left forebeam, an anti-overturn frame front protective net and a top plate, and is characterized in that the top plate is covered above a main structure frame formed by welding and building the side beam, the front upright post, the cross beam, the left rear upright post and the right rear upright post; the main structure frame is connected onto a machine body through the front bracket, the left bend plate soldering part, the right bend plate soldering part, the left bracket soldering part and the right bracket soldering part; two ends of the left forebeam and two ends of the right forebeam are respectively connected onto the side beam and the machine body; the anti-overturn frame front protective net is covered above the left forebeam and the right forebeam; and the anti-overturn frame rear protective net is covered on the left rear upright post and the right rear upright post. The six-column anti-overturn protection device has the benefits that when the dozer is in operation under the condition of being not equipped with a driving cab, a necessary life protection can be provided for operating staff.
Description
Technical field
The utility model belongs to engineering machinery class vehicle to be prevented turning over protective device, relates in particular to the anti-roll and the anti-junk protective device of crawler dozer.
Background technology
Export the bulldozer of tropic countries such as Africa at present,, do not require equipped driver's cabin owing to receive the microclimate condition restriction; But tropical rain forest operation; Condition of work is abominable, and the not equipped driver's cabin of bulldozer gets into and wherein carries out the modern operation of forest, can cause serious threat to the life and health of human pilot.
The utility model content
The utility model is to solve bulldozer and during equipped driver's cabin operation, a kind of anti-roll and anti-junk protective device is provided in tropical rain forest or weather hot area, effectively protects the life security of human pilot.
The utility model is for realizing above-mentioned purpose; Adopt following technical scheme: the anti-protective device that turns over of a kind of six posts; It comprises protecting wire net before protecting wire net behind curb girder, front column, preceding bracket, crossbeam, left back column, left bracket component, left bent plate soldering member, right curved plate soldering member, right bracket component, right back column, the anti-translation frame, right front beam, left front beam, the anti-translation frame, top board; It is characterized in that: said top board covers the main structural framework top of being built by curb girder, front column, crossbeam, left back column and the welding of right back column; Main structural framework is connected on the body through preceding bracket, left bent plate soldering member, right curved plate soldering member, left bracket component, right bracket component; Left front beam and right front beam two ends are connected on curb girder and the body; Protecting wire net covers left front beam, right front beam top before the anti-translation frame, and protecting wire net covers on left back column, the right back column behind the anti-translation frame, and its middle cross beam, curb girder, left front beam, right front beam, front column, left back column, right back column are hollow fine strain of millet.
The beneficial effect of the utility model: when bulldozer is not equipped with driver's cabin, can necessary life protection be provided for operating personnel.

1. protecting wire net 12. right front beam 13. left front beams 14. were prevented preceding protecting wire net 15. top boards of translation frames after bracket 4. crossbeams 5. left back column 6. left bracket component 7. left bent plate soldering member 8. right curved plate soldering members 9. right bracket component 10. right back columns 11. were prevented translation frames before curb girder 2. front columns 3.
The specific embodiment
Like Fig. 1; 2; Shown in 3; The anti-protective device that turns over of six posts is covered the main structural framework top of being built by curb girder 1, front column 2, crossbeam 4, left back column 5 and 10 welding of right back column by top board 15; Left back column 5, right back column 10 are connected on the bulldozer wing plate through left bracket component 6, right bracket component 9, and front column 2 is connected on wing plate and the body through preceding bracket 3 and left bent plate soldering member 7, right curved plate soldering member 8, and right front fine strain of millet 12, left front fine strain of millet 13 two ends are connected with bulldozer machine front shroud with curb girder 1 respectively through high-strength bolt; Protecting wire net 14 covers left front beam 13, right front beam 12 tops before the anti-translation frame, and protecting wire net 11 covers on left back column 5, the right back column 10 behind the anti-translation frame.
Through above-mentioned embodiment, prevent that turning over protective device has had following function:
1, six post frameworks of rigidity have had certain anti-roll ability, have guaranteed mental awareness.
2, before top board 15, the anti-translation frame behind protecting wire net 14 and the anti-translation frame protecting wire net 11 can effectively stop the injury of obstruction and junk to the bulldozer human pilot, thereby the life security of protection human pilot.
The above only is the preferred embodiment of the utility model, is not the structure of the utility model is done any pro forma restriction.Every technical spirit according to the utility model is to any simple modification, equivalent variations and modification that above embodiment did, all still belongs in the scope of technical scheme of the utility model.
