Abstract
The invention discloses a track beam for an excavator. The track beam comprises a beam body and an off foot plate and is characterized in that the beam body and the off foot plate are detachably connected. According to the track beam, on the basis that the off foot plate and the track beam are firmly connected, the track beam is convenient to dismount and mount in the case of the damage of the off foot plate, so that the production efficiency is improved.
Description
Technical field
The invention belongs to excavating machine parts, be specifically related to crawler beam of excavator.
Background technology
In prior art, on the track beam of excavating machine, the installation form of stretcher of getting off is the assigned address that is directly welded on the left and right track beam of getting off, although this form is enough firm, excavating machine is usually worked under rugged environment, and the stretcher of getting off is very easily impaired, once impaired, due to fixing welding, remove difficulty, maintenance difficulty is large; Meanwhile, because will get off stretcher and track beam are connected firmly, need at least four weld seams of welding welding, welding difficulty, is difficult for producing.
Summary of the invention
Technical matters to be solved by this invention is to provide crawler beam of excavator, by the get off annexation of stretcher and track beam of change, on the basis being connected firmly, in the situation that the stretcher that makes to get off damages, removes and facilitates at guarantee to get off stretcher and track beam.
For solving the problems of the technologies described above, the invention provides crawler beam of excavator, it comprises the Liang Tihe stretcher of getting off, beam body and the detachable connection of stretcher of getting off.
On described beam body, by the form of spot welding, be welded with captive nut, the stretcher of getting off is connected with beam body with captive nut by bolt.
Described captive nut arranges four groups, and along getting off, stretcher Central Symmetry respectively arranges two groups.
Crawler beam of excavator proposed by the invention, on the basis being connected firmly at guarantee to get off stretcher and track beam, in the situation that the stretcher that makes to get off damages, it is convenient to remove, and the while is easy for installation, has improved production efficiency.
Accompanying drawing explanation
Fig. 1 is the crawler beam of excavator structural representation in background technology.
Fig. 2 is the birds-eye view schematic diagram of Fig. 1.
Fig. 3 is crawler beam of excavator structural representation proposed by the invention.
Fig. 4 be Fig. 3 birds-eye view schematic diagram.
The specific embodiment
Referring to attached Fig. 1 and 2, the track beam beam body 1 in background technology is fixedly connected with by four weld seams 3 with the stretcher 2 of getting off, although connect firm, get off stretcher damage in the situation that, remove inconvenience, maintenance difficult, simultaneously the track beam of this structure produce be difficult for.
Referring to accompanying drawing 3 and 4, crawler beam of excavator, it comprises beam body 1 and the stretcher 2 of getting off, beam body and the detachable connection of stretcher of getting off.
On described beam body, by the form of spot welding, be welded with captive nut 5, the stretcher of getting off is connected with beam body with captive nut by bolt 4.
Described captive nut arranges four groups, and along getting off, stretcher Central Symmetry respectively arranges two groups.
Crawler beam of excavator proposed by the invention, on the basis being connected firmly at guarantee to get off stretcher and track beam, in the situation that the stretcher that makes to get off damages, it is convenient to remove, and the while is easy for installation, has improved production efficiency.
Claims (3)
