Examples
As shown in fig. 1 to 3, the anti-falling crawler traveling unit of the embodiment comprises a traveling bracket 1, wherein the front end of the traveling bracket is provided with a tensioning wheel 2, the rear end of the traveling bracket is provided with a driving wheel 3, a crawler chain 4 is sleeved on the tensioning wheel 2 and the driving wheel 3, a pair of front baffles 5 for blocking the crawler chain 4 from transversely falling off from the tensioning wheel 2 are arranged at the front end of the traveling bracket 1, and a pair of rear baffles 6 for blocking the crawler chain 4 from transversely falling off from the driving wheel 3 are arranged at the rear end of the traveling bracket; the front baffle plate 5 and the rear baffle plate 6 are respectively provided with two baffle plates which are respectively arranged at two sides of the walking bracket 1, and the edges of the baffle plates protrude out of the track chain 4 and are higher than the ground. When the crawler engineering machinery turns, the crawler chain 4 generates larger tangential force due to friction with the ground, so that a trend of transverse movement relative to the walking bracket 1 is formed, and if the crawler chain 4 is separated from the crawler induction teeth and the induction plate at this time, the crawler chain 4 can be separated from the tensioning wheel 2 or the driving wheel 3 with high probability. According to the application, the front end of the walking bracket 1 is provided with the two front baffles 5, the rear end of the walking bracket 1 is provided with the two rear baffles 6, and the edges of the front baffles 5 and the rear baffles 6 are protruded out of the track chain 4, so that when the track chain 4 moves transversely relative to the walking bracket 1, the side edges of the track chain 4 are pushed by the front baffles 5 and/or the rear baffles 6, and the probability that the track chain 4 falls off from the tensioning wheel 2 or the driving wheel 3 can be reduced to a certain extent. The anti-drop crawler travel unit is required to travel on the ground, so that the edges of the front baffle plate 5 and the rear baffle plate 6 are higher than the ground so as not to generate friction.
In this embodiment, gaps exist between the front barrier 5 and the track chain 4, and between the rear barrier 6 and the track chain 4. The anti-drop crawler belt traveling unit rotates relative to the traveling support 1 in the moving process, and gaps are formed between the front baffle plate 5 and the crawler belt 4 and between the rear baffle plate 6 and the crawler belt 4, so that continuous friction between the crawler belt 4 and the baffle plate can be avoided.
In this embodiment, the front end of the walking bracket 1 extends laterally and is provided with a front support 7, and the front support 7 is connected to the front baffle 5. The rear end of the walking bracket 1 is provided with a rear supporting piece 8 at one side away from the driving wheel 3, and the rear supporting piece 8 is connected with a rear baffle 6. The driving wheel 3 is provided with a plurality of supporting rods 9 along the lateral direction, and the supporting rods 9 are connected with the other rear baffle 6. The supporting piece 7 is of a plate-shaped structure, one end of the supporting piece is fixedly connected with the walking bracket 1, and the other end of the supporting piece is detachably connected with the front baffle plate 5 through bolts. The rear supporting piece 8 is of an arc plate-shaped structure, is arranged along the arc end face of the walking bracket 1, one end of the rear supporting piece is fixedly connected with the walking bracket 1, and the other end of the rear supporting piece is detachably connected with the rear baffle 6 through bolts. The tailgate 6 connected to the driving wheel 3 is provided in a ring-shaped plate structure detachably connected to the driving wheel 3 via a supporting rod 9, which tailgate 6 follows the rotation when the driving wheel 3 rotates. Further, in order to reduce the dead weight, a plurality of lightening holes are formed on each of the front baffle plate 5 and the rear baffle plate 6.
In this embodiment, a pair of middle baffles 10 for blocking the track chain 4 from falling out transversely are installed in the middle section of the walking bracket 1, and the middle baffles 10 are two and are separately arranged on two sides of the walking bracket 1, and the edges of the middle baffles protrude out of the track chain 4 and are higher than the ground. The middle section of the walking bracket 1 is provided with a middle supporting piece 11 along the lateral extension, and the middle supporting piece 11 is connected with a middle baffle 10. The middle baffle plate 10 positioned on the outer side comprises an outer upper baffle strip 10-1 and an outer lower baffle strip 10-2, wherein the outer upper baffle strip 10-1 is connected with the outer lower baffle strip 10-2 through a beam plate 10-3, and the beam plate 10-3 is connected with a middle supporting piece 11. The inner middle baffle plate 10 comprises an inner upper baffle strip 10-4, the lower side of which is convexly provided with a mounting plate 10-5, and the mounting plate 10-5 is connected with a middle supporting piece 11. When the crawler engineering machinery runs on a side slope, the crawler chain 4 generates larger tangential force due to friction with the ground, so that a trend of transverse movement relative to the walking bracket 1 is formed, and if the crawler chain 4 is separated from the crawler induction teeth and the induction plate at this time, the crawler chain 4 can be separated from the tensioning wheel 2 or the driving wheel 3 with high probability. According to the application, the middle baffle plates 10 are arranged in the middle section of the walking bracket 1, and the edges of the middle baffle plates 10 protrude out of the track chain 4, so that when the track chain 4 moves transversely relative to the walking bracket 1, the side edges of the track chain 4 are pushed by the middle baffle plates 10, and the probability that the track chain 4 falls off from the walking bracket 1 can be reduced to a certain extent. Because the anti-drop crawler travel unit is required to travel on the ground, the edge of the middle baffle plate 10 is also higher than the ground so as to avoid friction. Specifically, the middle baffle plate 10 located at the outer side comprises an outer upper baffle strip 10-1 and an outer lower baffle strip 10-2, which are connected through a beam plate 10-3, the upper side part of the track chain 4 can be blocked by arranging the outer upper baffle strip 10-1, and the lower side part of the track chain 4 can be blocked by arranging the outer lower baffle strip 10-2. In order to avoid interference, the inner side of the walking bracket 1 is connected with the outer structure of the engineering machinery, and the middle baffle plate 10 positioned at the inner side is only provided with the inner upper baffle strip 10-4, so that the upper side part of the track chain 4 can be blocked by utilizing the inner upper baffle strip 10-4.
In this embodiment, a plurality of traction wheels 12 are arranged at intervals on the upper side of the walking bracket 1, and a plurality of bogie wheels 13 are arranged at intervals on the lower side. Because the dead weight of the track chain 4 is large, if only the tensioning wheel 2 and the driving wheel 3 are arranged, the middle part of the track chain 4 is easy to bend downwards, and the dragging wheel 12 is arranged at intervals on the upper side of the walking bracket 1, so that a better bearing effect can be generated. And through setting up bogie wheel 13 at the interval of walking support 1 downside for walking support 1 atress more disperses, thereby alleviate the bearing pressure of take-up pulley 2 and drive wheel 3.
