Track shoe

Technical Field

The utility model relates to the technical field of conveyors, in particular to a track shoe.

Background

The crawler chain plate conveyor consists of a machine body, a crawler plate, a crawler chain, a driving chain wheel, a driven wheel and the like, wherein the crawler chain consists of a chain rail section, and the crawler plate is arranged on the crawler chain to form the crawler chain plate.

Detailed Description

The objects, technical solutions and advantages of the present utility model will become more apparent by the following detailed description of the present utility model with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.

The specific embodiment is as follows: in combination with fig. 1-4, two ends of a track shoe are respectively provided with a blank pressing structure 1 and a lug structure 3, the upper side surface of the lug structure 3 and the lower side surface of the blank pressing structure 1 are arc surfaces coaxial with two pin shaft holes of a track link to be installed respectively, the radii of the two arc surfaces are equal, when the track shoe is used, the blank pressing structure 1 on the rear track shoe is pressed on the lug structure 3 on the front track shoe, and when the adjacent track shoe relatively rotates within a certain range by taking the pin shaft hole as an axis, the lower side surface of the blank pressing structure 1 can keep contact with the upper side surface of the lug structure 3, and no gap exists. The side of the blank pressing structure 1, which is close to the lug structure 3, is provided with the groove 2, the groove cannot be contacted with the upper side surface of the lug structure 3, friction force is reduced, and the adjacent track shoes can rotate relatively easily. The track shoe is further provided with a plurality of connecting holes 7, the positions of the connecting holes 7 correspond to the positions of the mounting holes on the caterpillar links, and the track shoe is conveniently fixed on a caterpillar chain by bolts and nuts. The lug structure 3 is provided with a plurality of notches 8, when the track link plate moves from the horizontal tail part to the inclined section, the track link plate is bent upwards, and at the moment, the notch 8 on the front track plate can accommodate the front part of the track link on the rear track chain, so that interference between the track plate and the track chain is avoided.

Further, the track shoe is provided with protruding 4 and first protruding muscle 6 at its both ends of one side that the track chain was kept away from respectively, protruding 4 is located the one end that is close to blank holder structure 1, first protruding muscle 6 is located the one end that is close to lug structure 3, protruding 4 and first protruding muscle 6 have not only strengthened the intensity of track shoe, have improved the ability of track shoe's promotion material moreover.

Further, the second convex rib 5 is arranged in the middle of one side, far away from the track chain, of the track plate, so that the strength of the track plate is enhanced, and the capability of lifting materials of the track plate is improved.

Further, the second protruding rib 5 is located in the middle of the two rows of connecting holes 7, when the track shoe is used, the head of the bolt is located on the upper side of the upper surface of the track shoe, the height of the second protruding rib 5 is higher than that of the top end of the head of the bolt, the height of the protrusion 4 and the height of the top end of the head of the first protruding rib 6 are also higher than that of the top end of the head of the bolt, so that the head of the bolt is not easy to be impacted by falling materials when being loaded, and abrasion to the head of the bolt is reduced.

Further, as shown in fig. 3, the inner side surface of the notch 8 is inclined with the bottom surface of the track plate, so that the size of the upper portion of the notch 8 is smaller than the size of the lower portion in the left-right direction, and the purpose of completely covering the notch 8 is easier to achieve by the edge pressing structure 1 when two adjacent track plates are located on the same plane.
