Description
Technical field
The utility model relates to load mechanism technology for making field, the connection structure of especially a kind of Rear frame of loader and operator's compartment.
Background technology
Traditional Rear frame of loader and the connection structure of operator's compartment are for being rigidly connected, and in the use procedure of loader, the vibration of vehicle frame is directly passed to operator's compartment, and the vibration of operator's compartment is large and noise is larger, and the traveling comfort of therefore driving is poor.
Utility model content
The technical problems to be solved in the utility model is to provide the connection structure of a kind of Rear frame of loader and operator's compartment, has good damping effect, is conducive to improve the traveling comfort of driving.
For achieving the above object, the technical solution of the utility model is: the connection structure of a kind of Rear frame of loader and operator's compartment, comprise rear vehicle frame, operator's compartment, on rear vehicle frame, fix four upper end surfaces in the supporting seat of same level, the upper surface of each supporting seat offers an assembly opening, on the base plate of operator's compartment, offer the assembly opening of corresponding four the supporting seat upper surfaces of four through holes, on each described assembly opening, cushion blocking is housed, described upper cushion blocking outer peripheral face is that ladder is cylindrical, the centre of upper cushion blocking is provided with centre hole, the head lower surface of upper cushion blocking is attached to the upper surface of supporting seat, the outer peripheral face at upper cushion blocking middle part matches with the inside face of described assembly opening, upper cushion blocking lower, outer perimeter face is through described assembly opening and lower cushion blocking phase fit with central through hole, the lower surface of bottom plate of driving cab is erected at the through hole that utilizes bolt to pass on bottom plate of driving cab on the upper surface of cushion blocking head and with upper cushion blocking centre hole, operator's compartment is connected with rear vehicle frame, the lower end lock of bolt has nut.
Further improve, the center borehole jack of described upper cushion blocking has an anti-wearing liner to match with bolt.To extend the service life of upper cushion blocking.
Further improve, described bolt lower end is also overlapped and is had spring chair and irony pad successively on nut, matches with the lower surface of lower cushion blocking in the upper surface of irony pad.Prevent that screw bolt and nut from occurring loosening.
Preferred described supporting seat comprises two side plate and the horizontally disposed top boards that vertically arrange, and described assembly opening is opened on top board.With upper cushion blocking convenient for assembly, lower cushion blocking, screw bolt and nut.
The utility model operator's compartment is to be connected by upper cushion blocking, lower cushion blocking and the supporting seat being fixed on rear vehicle frame with being connected of rear vehicle frame, upper cushion blocking outer peripheral face is that ladder is cylindrical, there is certain deflection, upper cushion blocking lower, outer perimeter face is again through described assembly opening and lower cushion blocking phase fit with central through hole, therefore operator's compartment and rear vehicle frame can do relative displacement in top to bottom, left and right, front and rear, the vibration of rear vehicle frame just can not be directly passed to operator's compartment, can reduce vibration and the noise of operator's compartment, improve the traveling comfort of driving.

Detailed description of the invention
Below in conjunction with accompanying drawing and concrete embodiment, the utility model is described in further detail.
Shown in Fig. 1 to Fig. 4, the connection structure of a kind of Rear frame of loader and operator's compartment, comprise rear vehicle frame 1, operator's compartment 2, on rear vehicle frame 1, fix four upper end surfaces in the supporting seat 3 of same level, the upper surface of each supporting seat 3 offers an assembly opening, on the base plate of operator's compartment 2, offer the assembly opening of corresponding four supporting seat 3 upper surfaces of four through holes, described supporting seat 3 comprises two side plate 31 and the horizontally disposed top boards 32 that vertically arrange, and described assembly opening is opened on top board 32;
On each described assembly opening, cushion blocking 4 is housed, described upper cushion blocking 4 outer peripheral faces are that ladder is cylindrical, the centre of upper cushion blocking 4 is provided with centre hole 41, head 42 lower surfaces of upper cushion blocking 4 are attached to the upper surface of supporting seat 3, the outer peripheral face 43 at upper cushion blocking 4 middle parts matches with the inside face of described assembly opening, upper cushion blocking 4 lower, outer perimeter faces 44 are through described assembly opening and lower cushion blocking 5 phase fits with central through hole 51, the lower surface of operator's compartment 2 base plates is erected at the through hole that utilizes bolt 6 to pass on operator's compartment 2 base plates on the upper surface of cushion blocking 4 heads 42 and with upper cushion blocking 4 centre holes 41, operator's compartment 2 is connected with rear vehicle frame 1, the lower end lock of bolt 6 has nut 7.
The center borehole jack of described upper cushion blocking 4 has an anti-wearing liner 8 to match with bolt 6.
Described bolt 6 lower ends are also overlapped and are had spring chair 9 and irony pad 10 successively on nut 7, match with the lower surface of lower cushion blocking 5 in the upper surface of irony pad 10.
Below be only preferred embodiment of the utility model, the change that those skilled in the art does to be equal to by claim all falls into the protection domain of this case.
