Embodiment Construction
[0017] figure 1 and figure 2 A preferred embodiment of the present invention is shown.
[0018] like figure 1 figure 2 As shown, the bottom of the ROPS bottom beam 1 is provided with a U-shaped plate 2, the opening of the U-shaped plate 2 is upward, and the open end is welded with both sides of the bottom beam 1, and an upper through hole 5 is provided at the bottom of the U-shaped plate 2. , There is a lower through hole 7 on the frame 9. In order to use the standard bolts 6 and nuts 3, an upper pad 4 is arranged in the U-shaped plate 2, and a lower pad 8 is sleeved on the inside of the head of the bolt 6 , there is a gap between the upper plane of the lower block 8 and the frame 9 . The threaded end of the bolt 6 passes through the lower through hole 7, the upper through hole 5 and the upper spacer 4 and is threadedly connected to the nut 3, wherein the diameters of the upper through hole 5 and the lower through hole 7 are larger than the diameter of the bolt 6, and th...

The invention relates to a safety mechanism capable of preventing a roll over protection system (ROPS) from being separated from an automobile frame and aims to overcome the defects that the conventional safety mechanism capable of preventing the ROPS from being separated from the automobile frame occupies the inner space of a cab and is inconvenient to assemble. The safety mechanism comprises the ROPS, the automobile frame and a safety pull rod device, wherein the safety pull rod device comprises a bolt, a nut and a U-shaped plate; the open end of the U-shaped plate is welded with a bottom transverse beam of the ROPS; coaxial through holes are formed at the bottom of the U-shaped plate and on the automobile frame; the threaded end of the bolt passes through the through holes on the automobile frame and the U-shaped plate and is in threaded connection with the nut in the u-shaped plate; the threaded end of the bolt is fixedly connected with the U-shaped plate; no rigid connection exists between the head of the bolt and the automobile frame; the walls of the through holes are in clearance fit with the rod part of the bolt; and when the ROPS and the automobile frame move relatively and staggeredly, the two ends of the bolt can rotate along with the moving directions of the ROPS and the automobile frame and are connected with the ROPS and the automobile frame. The safety mechanism is convenient to assemble and does not occupy the inner space of a cab.
Description
technical field [0001] The invention relates to a driver protection mechanism, in particular to a safety mechanism for preventing ROPS from being separated from a vehicle frame when a vehicle rolls over. Background technique [0002] A rollover protection structure (ROPS) is a driver protection safety device commonly used in construction machinery, which provides protection for the driver when the machine rolls over. The ROPS of some construction machinery is used as the skeleton of the driver's cab and is a part of the driver's cab. This kind of ROPS usually uses a suspension device such as a silicone oil shock absorber to install the ROPS on the frame to realize the shock absorption of the cab. However, the bearing capacity of this type of shock absorber is weak. When the machine overturns, after the shock absorber of the cab is destroyed, the ROPS will be separated from the frame, which may cause the failure of the ROPS protection function and cause personal injury.
