Description
The present invention relates to be installed in the connection rod-type rubber belt track on the bottoms such as walking vehicle for construction, civil engineering machinery.
In the past, in walking building mechanism, used the steel crawler belt bar none, yet, more and more in recent years rubber belt tracks that use.Owing in the steel crawler belt, become continuous runner track above the crawler belt connecting rod, vibration is little when making walking, circumferentially, lateral excursion does not take place yet, thereby less generation crawler belt comes off with wide to not stretching, in addition, also have because of each crawler belt connecting rod room machine Joint strenght height, thus advantage such as durability is good, yet, it but exists noise big on the other hand, resiliency is poor, easily makes the operator produce fatigue, and easily makes shortcomings such as road surface damaged.
In contrast, rubber belt track has that noise is low, resiliency good, do not damage the road surface and light, can make advantages such as the speed of travel is very fast, yet, its weak point is because of bad mechanical strength, so durability is not as good as the steel crawler belt, for unusual big external force, circumferentially elongation easily takes place and widely cause crawler belt to come off to reversing and produce problem such as the vibration of walking because of the runner track is discontinuous.
On Japanese patent laid-open 4-71386 number (denomination of invention: connect the rod-type rubber belt track) communique of present inventor's previous application, once proposed to be used for traditional rubber belt track by some structure with the steel crawler belt, the advantage that is had with the steel crawler belt solves the connection rod-type rubber belt track of the above-mentioned shortcoming of traditional rubber belt track, aftermentioned Fig. 8 A～C represents an embodiment of this structure, A is birds-eye view (kiss the earth one side), and B and C are respectively along the B-B line of A and the section-drawing of C-C line.Among the figure, 15 is the rubber belt track body, and 15a is the alar part projection, 15b is a center projections, and 16 for axle 16a is an alar part, the curve of 15c for rubber body 15 bendings are formed, 15d is the hole of hollow, and 16b is for forming the central portion of concavity, and 16p is a bolt hole, 17 is the crawler belt connecting rod, 17a is a window, and 17p is a bolt hole, and f and f ' are respectively screw bolt and nut, 18 is enhancement layer, and 19 is connecting rod pin.
In this structure, with each bolt hole 17p, 17p of a pair of crawler belt connecting rod 17,17 respectively with imbed rubber belt track body 15 in bolt hole 16p, the 16p of central portion 16b of the axle 16 back bolt of aliging, and the two ends that connect crawler belt connecting rod 17 with connecting rod pin 19, formation is by the continuous runner track that forms with the paired crawler belt connecting rod 17 of interior all bonded assemblys of rubber belt track body 15, make when walking vibration little, crawler belt takes place hardly come off.
Now the problem that will solve the present invention's first scheme is described below.
As shown in Figure 9, in coiling portion towards connection rod-type rubber belt track drive wheel or idle pulley, the outer circumferential side elongation of the connection lead of connecting rod pin 19,19, the part of burying underground of axle 16 is not extended, extend thereby make between the axle, when this part elongation reached very big, the fatigue that cyclic extension produces just can accumulate, thereby influences its durability.In the structure that proposes by above-mentioned Japanese patent laid-open 4-71386 number, rubber belt track body 15 all lateral bending songs in rubber belt track stretch out between axle by making, form curve 15c, thereby the amount of tension when guaranteeing to reel, and by enhancement layer 18 being imbedded in the rubber belt track body 15 in order to keep its durability, yet, because this enhancement layer 18 can not excessively extend, as this curve 15c and connecting rod pin 19 formed when roughly contour, then rubber bodies elongation and enhancement layer does not extend when reeling may be concentrated and be cut off by Yin Lali enhancement layer.
In addition, in various Work machines, what have is preventing that near the setting of idle pulley place guide and the anti-stone baffle plate that crawler belt comes off, Figure 10 from being to be illustrated in the structure that above-mentioned rubber belt track car body 15 is installed on the crawler attachment that possesses anti-stone baffle plate 20, A is a lateral plan, and B is the Z-Z line section-drawing along A.Wherein, 21 is the car body frame of running gear, and 22 is idle pulley, and 23 is runner, and 24 are the key wheel.For such device, structurally,, just may produce and inappropriate situations such as the anti-stone baffle plate of body contacts in case curve 15c is bent to till the position of connecting rod pin 19.
Therefore, the present invention's first scheme, in order to address the above problem, purpose is to provide and can adapts to the connection rod-type rubber belt track that various Work machines are installed just.
The connection rod-type rubber belt track of the present invention's first scheme is with by a left side, the length of the axle that right wing part and central portion are formed to relative rubber belt track body circumferentially vertically, bury underground by roughly certain interval, above or below described alar part or up and down two sides bury enhancement layer underground, while is established lug boss in a side of the kiss the earth of this body, the crawler belt connecting rod is installed in upper central portion both sides at this axle, the crawler belt connecting rod of front and back is connected into the state of bending mutually, form track with a pair of continuous crawler belt connecting rod, it is characterized in that, the rubber belt track body between the axle of burying underground is made accordion-like.In addition, can with described enhancement layer oblique imbed the axle alar part above or below or two sides up and down.And then, the central portion of imbedding axle can be formed invaginated type by relative left and right sides alar part.
In this first scheme, because the rubber belt track body that will connect between the axle that the rod-type rubber belt track buries underground is made accordion-like, the elongation in the time of fully guaranteeing on drive wheel, idle pulley coiling prevents to produce the rubber fatigue accumulation that causes because of cyclic extension.In addition, even can not be in the rubber belt track body because of anti-stone baffle plate etc. all sides form in the running gear of extension and also can install.
In addition, because the oblique enhancement layer of imbedding of two sides above or below the axle alar part that connects the rod-type rubber belt track or up and down makes enhancement layer self can produce some elongations, thereby enhancement layer can not take place be cut off because of inappropriate stretching.

10Rubber belt track plate 407 configuration be connected and connect between rod-type crawler belt end.With axle 401 with have the connecting strap 413 that is equivalent to these rubber belt track plate 407 whole circumferential lengths and imbed in this rubber belt track plate 407, this connecting strap 413 is formed and possess along the front and back of rubber belt track plate 407, the concavity section of overlapping 413t, 413 ' t stretching out of side obliquely, make its in connecting rod pin 406 positions respectively with overlapping the 412t in crawler belt end, the overlapping connection of 412 ' t.
Figure 25 is the circumferential section-drawing of the connection rod-type rubber belt track of another other example of expression this programme, and expression is imbedded the axle of axle alar part 410a and connecting strap 410k, 410 ' k formation one, has to be equivalent to a joint crawler belt connecting rod circumferential lengths L
10Rubber belt track plate 408, make this connecting strap 410k, 410 ' k from oblique the erecting in axle alar part 410a rear and front end, and the connecting strap end is stretched out in the rubber bodies and form overlapping 410t, 410 ＇ t.Expression is with these rubber belt track plate 408 circumferentially assortments of edge in this example, the overlapping portion that makes butt joint is at connecting rod pin location overlap roughly, simultaneously, connect front and back rubber belt track plate 408, become the connection rod-type rubber belt track that only constitutes full week with rubber belt track plate 408 with crawler belt crawler belt connecting rod.
According to this cubic case, owing to not using bolt etc. to use the connecting strap of simple structure to connect, thereby bolt fracture does not take place, inappropriate situation such as loose, constitute make connect and repair work easily, cheap connection rod-type rubber belt track economically.
In addition, owing to make the connecting strap overlapping part in the connecting rod pin position, thereby the portion's opening phenomenon of reeling on sprocket wheel or do not overlap during reflex action, thereby can prevent that foreign matter from entering respectively connects the place, and walking is carried out smoothly.
