Abstract
The utility model discloses a bulldozer for a mine, which comprises a push broach, wherein a plurality of reinforcing ribs are arranged at the inner side of the push broach and are rectangular steel plate blocks welded at the inner side of the push broach. As the plurality of reinforcing ribs are welded at the inner side of the push broach, the stress intensity of the push broach is greatly improved, and the service life of the push broach is prolonged.
Description
Technical field
The utility model relates to a kind of mining machinery, and bulldozer is used in particularly a kind of mine.
The background technology bulldozer is widely used in the mining operation.Because work under bad environment; In use working strength is big to add bulldozer, and the stress intensity of bulldozer push broach knife plate is obviously not enough, and the push broach knife plate is using begin to crack in the surface later half a year; Use push broach knife plate fracture after a year, must change.Cost of production is increased greatly.
The utility model content
The technical problem that the utility model will solve provides the mine that a kind ofly strengthens the push broach stress intensity, prolongs push broach application life and uses bulldozer.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is: bulldozer is used in a kind of mine, comprises push broach, and said push broach inboard is provided with many reinforcing ribs.
Said reinforcing rib is to be welded on the inboard cuboid steel plate piece of push broach.
The beneficial effect of the utility model: owing to welded many reinforcing ribs, strengthened the stress intensity of push broach widely, prolonged the application life of push broach in the push broach inboard.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.
Fig. 1 shows the concrete structure of the utility model.Bulldozer push broach 2 inboards are welded with polylith cuboid steel plate piece as reinforcing rib, and cuboid steel plate piece is that the steel plate cutting of 15mm forms by thickness.During welding, confirm to select the different sizes and the cuboid steel plate piece of quantity according to bulldozer push broach 2 inner surface shapes and different stressing conditions.To the push broach lower edge of surfacing, stressed maximum, the steel plate piece 1 long with 15cm, that 10cm is wide adopts laterally closely welding manner, has strengthened surface stress and skin friction when having met push broach 2 inner surface shapes; For push broach 2 intermediate surface the situation of radian is arranged, adopt the fritter steel plate 4 that 10cm is long, 5cm is wide to carry out the oblique parallel welding, so not only increased its skin friction but also made the surface stressed evenly, effectively avoided coming off of welding steel; For the upper edge of push broach 2 surfacings, adopt the steel plate piece 3 that 20cm is long, 15cm is wide to carry out alternate anyhow welding manner, effective like this target that stoped when bulldozing is for the impact of relatively thinner knife plate top work plane.
