Abstract
The utility model discloses an excavator lower frame tacking slide rail mechanism, which comprises a left crawler beam base plate and a left crawler beam tensioning mechanism which are fixed on the left of a main body, a middle X frame positioning device, a regulating screw and a cylinder which are fixed in the middle of the main body, a right crawler beam base plate and a right crawler beam tensioning mechanism which are fixed on the right of the main body, and a guide rail and a sliding support which are fixed on the left or right of the main body, wherein the left crawler beam base plate and the right crawler beam base plate are fixedly provided with a crawler beam pin roll respectively; and the sliding support is fixed on the guide rail. The excavator lower frame tacking slide rail mechanism has the advantage that the service life of an excavator lower frame is prolonged.
Description
Technical field
The utility model relates to a vehicle frame assembly point sliding track mechanism under a kind of excavator, belongs to vehicle frame assembly point apparatus technical field under the excavator.
Background technology
When the excavator vehicle frame is pieced together point, generally be with steady pin left and right sides crawler belt beam to be fixed earlier, middle X frame be positioned between left crawler belt beam and the right-hand track chiain beam; When adopting this kind mode to place, middle X frame is not easy to place, and places the also difficult adjustment in its position, back of entering; Therefore, after middle X frame is placed, easily and gapped between left crawler belt beam or the right-hand track chiain beam; In this case, in follow-up welding process, be difficult for also easy deformation of welding and welding back crawler belt beam.
Summary of the invention
Problem to above-mentioned prior art existence; The utility model provides a vehicle frame assembly point sliding track mechanism under a kind of excavator; Through the cooperation of slide rail and sliding support, it is more tight when piecing together point, left crawler belt beam, right-hand track chiain beam and middle X frame to be cooperated, and is beneficial to next step welding operation.
To achieve these goals, the technical scheme that the utility model adopts is: vehicle frame is pieced together the some sliding track mechanism under a kind of excavator, comprises the left crawler belt girder bearing plate that is fixed on the mechanism body left side, and left crawler belt beam steps up mechanism; Be fixed on middle X frame positioner, adjustment screw mandrel and the oil cylinder of mechanism body middle part; The right-hand track chiain girder bearing plate and the right-hand track chiain beam that are fixed on the mechanism body right side step up mechanism; Be fixed with crawler belt beam bearing pin respectively on left side crawler belt girder bearing plate and the right-hand track chiain girder bearing plate; Also comprise the guide rail and the sliding support that are fixed on mechanism body left side or right side, sliding support is fixed on the guide rail.
Preferably, said middle X frame positioner adopts the bearing pin location.
The beneficial effect of the utility model is: on mechanism body, be provided with guide rail and sliding support; When operation; Through sliding support moving on guide rail, the gap between adjustment crawler belt beam and the middle X frame makes the cooperation between left crawler belt beam, middle X frame, the right-hand track chiain beam more tight; Be convenient to the carrying out of next step welding job, thereby improved the service life of vehicle frame under the excavator.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the use sketch map of the utility model.
Among the figure: 1, left crawler belt girder bearing plate, 2, left crawler belt beam steps up mechanism, 3, middle X frame positioner, 4, the adjustment screw mandrel; 5, oil cylinder, 6, the right-hand track chiain girder bearing plate, 7, the right-hand track chiain beam steps up mechanism; 8, crawler belt beam bearing pin, 9, guide rail, 10, sliding support; 11, left crawler belt beam, 12, middle X frame, 13, the right-hand track chiain beam.
The specific embodiment
To combine accompanying drawing and embodiment that the utility model is described further below.
As shown in Figure 1: the utility model comprises the left crawler belt girder bearing plate 1 that is fixed on the mechanism body left side, and left crawler belt beam steps up mechanism 2; Be fixed on middle X frame positioner 3, adjustment screw mandrel 4 and the oil cylinder 5 of mechanism body middle part; The right-hand track chiain girder bearing plate 6 that is fixed on the mechanism body right side steps up mechanism 7 with the right-hand track chiain beam; Be fixed with crawler belt beam bearing pin 8 respectively on left side crawler belt girder bearing plate 1 and the right-hand track chiain girder bearing plate 7; Also comprise the guide rail 9 and sliding support 10 that are fixed on mechanism body left side or right side, sliding support 10 is fixed on the guide rail 9.
Preferably, said middle X frame positioner 3 adopts the bearing pins location.
Embodiment:
The use of the utility model is as shown in Figure 2: when guide rail 9 and sliding support 10 are fixed on the mechanism body left side; Under piecing together some during vehicle frame; At first be put into right-hand track chiain beam 13 on the right-hand track chiain girder bearing plate 6, and, step up mechanism 7 with the right-hand track chiain beam and step up with on crawler belt beam bearing pin 8 pins; Left side crawler belt girder bearing plate 1 installs on the sliding support 10, then the middle X frame of middle X frame 12 usefulness positioner 3 location, again with 4 leveling of adjustment screw mandrel; Be put into left crawler belt beam 11 on the left crawler belt girder bearing plate 1 and at last and sell, and step up mechanism 2 with left crawler belt beam and step up with 1 crawler belt beam bearing pin 8, retract cylinder 5, sliding support 10 moves on guide rail 9, thereby adjusts the gap of left crawler belt beam 11 and middle X frame 12; Be convenient to closely cooperating between left crawler belt beam 11, middle X frame 12, the right-hand track chiain beam 13.
The use of this device was applicable to that simultaneously guide rail 9 and sliding support 10 are fixed on the state on mechanism body right side when in like manner, guide rail 9 was fixed on the mechanism body left side with sliding support 10.
