Abstract
The utility model discloses a guide mechanism of a track beam of an excavator. The guide mechanism of the track beam of the excavator comprises a bearing beam, wherein the front end of the bearing beam is fixedly connected with a guide device for assembling a guide wheel; the guide device comprises guide plates on the two sides and fixed U-shaped connecting plates on the upper and lower sides; a first reinforcing plate is arranged on the inner side of each guide plate; a second reinforcing plate is arranged on the outer side of each guide plate; the second reinforcing plates extend to the outside of the bearing beam and are connected and fixed. Through intensity reinforcement of the guide mechanism of the track beam and effective restriction of the guide wheel and a guide fit clearance, the guide mechanism of the track beam of the excavator solves the problems of movement and dropping of the guide wheel in the traveling process of the excavator and has the advantages of being rational in structure, safe, reliable and the like.
Description
Technical field
The utility model discloses a kind of crawler beam of excavator guiding mechanism, by International Patent Classification (IPC) (IPC), divides and belongs to crawler beam of excavator manufacturing technology field, especially relates to a kind of track beam track adjusting wheel anti-drop structure design.
Background technology
At present, the use of traxcavator is more and more extensive, but track adjusting wheel easily comes off in the course of the work, and job schedule is wasted time and energy, affects in repair.It is generally in excavating machine walking a period of time that track adjusting wheel comes off, and its both sides guiding mechanism is because undercapacity causes outer, and track adjusting wheel is large with guiding tolerance clearance, thereby causes track adjusting wheel to be rocked greatly, severe patient generation obscission.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of crawler beam of excavator guiding mechanism, the problem that solve excavating machine walking process track adjusting wheel play, comes off.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of crawler beam of excavator guiding mechanism, comprise support beam, this support beam front end is fixedly connected with the guide piece of assembling track adjusting wheel, guide piece comprises the guide plate of both sides and the fixing U-shaped connecting panel of upper and lower sides thereof, in guide plate inner side, be provided with the first brace panel, brace panel with on guide plate, all have the bar hole matching, in guide plate outside, be provided with the second brace panel, the second brace panel extends to support beam outside and is connected and fixed.
Further, described the first brace panel is a pair of, is arranged on respectively on the guide plate of both sides, between the first brace panel, is controlled at 271-273mm, and four arris along its length of the first brace panel all form chamfering structure.
Further, the thickness of slab of described the first brace panel is 21-25mm.
Further, described the second brace panel is vertically mounted on guide plate outside, and be positioned at brace panel bar shaped hole above or below.
The utility model is applied to the technical reform scheme that comes off occurring after track beam track adjusting wheel is installed, by effective restriction of the intensity reinforcement of track beam guiding mechanism and track adjusting wheel and guiding tolerance clearance, the problem that solve excavating machine walking process track adjusting wheel play, comes off, has the advantages such as rational in infrastructure, safe and reliable.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model guide piece front view.
Fig. 3 is guide piece lateral plan.
Fig. 4 is guide piece birds-eye view.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment: refer to Fig. 1 to Fig. 4, a kind of crawler beam of excavator guiding mechanism, comprise support beam 1, this support beam 1 front end is fixedly connected with the guide piece 2 of assembling track adjusting wheel, guide piece 2 comprises the guide plate 21 of both sides and the fixing U-shaped connecting panel 22 of upper and lower sides thereof, in guide plate 21 inner sides, be provided with the first brace panel 3, brace panel 3 all has with on guide plate 21 bar hole matching, in guide plate 21 outsides, being provided with the second brace panel 4, the second brace panels 4 extends to support beam 1 outside and is connected and fixed.The first brace panel of the present utility model is a pair of 31,32, welded and installed is on both sides guide plate 21 respectively, between the first brace panel, L is controlled at 271-273mm (271+2/0), and four arris along its length of the first brace panel 3 all form chamfering structure, and the thickness of slab of the first brace panel is 22mm.The second brace panel 4 of the present utility model is vertically mounted on guide plate 21 outsides, and be positioned at brace panel bar shaped hole above or below, wherein side second brace panel is two, opposite side the second brace panel is one.
The utility model improvement project and effect are as follows:
1. the utility model increases above two kinds of brace panels 3,4;
2. increase the part of welding the first brace panel (sequence number 3), dimensional control is at 271+2/0.
3. carry out road surface test, travelled distance 500km, the excavating machine 50km that often travels verifies that track adjusting wheel rocks surplus, gap length and give record, according to record result verification at every turn, rock surplus, gap all in dimension limit, effectively prevented excavating machine walking process track adjusting wheel play, the phenomenon coming off.
Above record, only, for utilizing the embodiment of this origination techniques content, modification, variation that any those skilled in the art use this creation to do, all belong to the scope of the claims that this creation is advocated, and be not limited to those disclosed embodiments.
