Abstract

A creeper tread for a pavement construction vehicle is characterized in that the creeper tread comprises an internally-arranged element (6), a rubber body (4) which enwraps the internally-arranged element (6), the rubber body (3) is equipped with a bottom surface (3) and the opposite side of the rubber body (3) is equipped with a top surface (13). A screw bolt (5) is fixed on the internally-arranged element (6) and the outer end of the screw bolt (5) extends out of the top surface (13) of the rubber body (4). The utility model has the advantages of abrasion resistance, easy dismounting and easy processing compared with prior technology.

Description

The caterpillar block of pavement engineering vehicle

Technical field

The utility model relates to a kind of caterpillar block of pavement engineering vehicle.

Background technology

In the prior art, various tracklaying vehicles, for example the crawler belt excluded on the various vehicleses such as machine, cement or asphalt pavement machine of grab excavator, aloft work machine, armored motor car, road surface is made up of chain and the caterpillar block that is contained on the chain, caterpillar block is one-body molded by rubber block and iron plate, be divided into two up and down, fix with bolt, its shortcoming is that dismounting is consuming time, the productive costs height.

Summary of the invention

The purpose of this utility model is to provide the caterpillar block of the pavement engineering vehicle of a kind of easy disassembling, long service life.

The technical solution of the utility model is: a kind of caterpillar block of pavement engineering vehicle, it comprises the rubber bodies of built-in part, the described built-in part of parcel, described rubber bodies has a bottom surface, an end face is arranged on the rubber bodies of the opposite side of bottom surface, be fixed with bolt on the described built-in part, stretch out outside the end face of described rubber bodies the outer end of this bolt.

The specific embodiment

Referring to accompanying drawing 5, a kind of caterpillar block of pavement engineering vehicle, it comprises built-in part [6], wraps up the rubber bodies [4] of described built-in part [6], described rubber bodies [4] has a bottom surface [3], on the rubber bodies [4] of the opposite side of bottom surface [3] end face [13] is arranged, be fixed with bolt [5] on the described built-in part [6], stretch out outside the end face [13] of described rubber bodies [4] outer end of this bolt [5].

Referring to accompanying drawing 5 and accompanying drawing 6, two relative sides of the close bottom surface [3] of described rubber bodies [4] all are skewed, be called first inclined-plane [2], two other relative side of the close bottom surface [3] of described rubber bodies [4] also is skewed, is called second inclined-plane [12].The face on the most close first inclined-plane [2] is and equidirectional bevelled inclined-plane, first inclined-plane [2] on the described built-in part [6].First inclined-plane [2] can band by first inclined-plane [2] when crawler belt turns round and tilt, but the large tracts of land kiss the earth reduces the wearing and tearing to rubber bodies [4], can play a supporting role to described first inclined-plane [2] in the equidirectional bevelled inclined-plane on the built-in part [6].

Described built-in part [6] on the face of end face [13] towards end face [13] protrude form in the middle of projection [17] and edge projection [18], make built-in part [6] that more stressed support portion be arranged.

The surface of described built-in part [6] is provided with many convex tendons [10], and described rubber bodies [4] matches with described convex tendon [10], and then rubber block [4] can be connected better and be difficult for peeling off with built-in part [6].

Described built-in part [6] is two and is arranged side by side within described rubber bodies [4].

As shown in Figure 7, described built-in part has through hole on [6], described bolt [5] passes described through hole, described through hole hole wall is provided with the axially extended a plurality of anti-slop serrations [11] along bolt [5], anti-slop serrations [11] can prevent effectively that bolt [5] from rotating in through hole, make to be connected securely between bolt [5] and the built-in part [6].In addition, the bight of built-in part [6] is an arc chord angle all, makes that rubber block [4] is evenly stressed.

The utility model compared with prior art has the advantage of wear-resistant, easy dismounting, handling ease.
