Description

  The present invention relates to a rubber crawler disassembly method and a disassembly apparatus used for a traveling body of a self-propelled working machine.

  A rubber crawler used for a traveling body of a self-propelled working machine has been widely used because it has a feature that the traveling road surface is not damaged. However, rubber crawlers are inferior in durability to iron crawlers, and a large number of used rubber crawlers are discarded along with crawler replacement. Since such rubber crawlers are provided with a large number of cored metal bases that engage with sprockets embedded in endless rubber, in order to reuse this waste rubber crawler, rubber and metal cores are used. Need to be separated. The separated rubber is reused as fuel or the like, and the core metal is processed as scrap. However, when disassembling the rubber crawler, it is necessary to separate the rubber and the iron, but there are various sizes and shapes, and the base of the cored bar made of iron is embedded in the rubber. It is difficult to separate and many waste rubber crawlers are often piled up and left unattended.

  As a conventional dismantling method and dismantling apparatus for separating such rubber crawlers, there are those described in Patent Documents 1 to 3. In order to improve the separation performance of the rubber crawler cut into a belt shape, the one described in Patent Document 1 heats the metal part with an induction heating coil, holds both sides of the rubber part, and uses the core metal in the center part. A method is adopted in which the cored bar is pressed by a presser body attached to a correspondingly provided cylinder and pushed out from the rubber part to be separated.

  The one described in Patent Document 2 conveys a rubber crawler in the longitudinal direction, applies heat to reduce the strength of the rubber being conveyed, and forcibly moves the rubber having reduced strength in the longitudinal direction, The rubber part is separated from the rubber by tearing the rubber part to the left and right by a wedge-shaped separating device facing the central part of the rubber crawler, and at the same time moving the core metal to the central part by the guide device while moving it. is there.

In the one described in Patent Document 3, the front and back portions of the core bar of the rubber crawler are pressed and fixed by a pressing device using a cylinder, the core bar is pushed out from one side of the left and right sides of the core bar by a punching device, and then the other The side is pushed out and separated.

  According to the method and apparatus described in Patent Document 1, the cored bar is induction-heated, so that the rubber is softened by heat, so that the peeling force of the rubber part is reduced, but the rubber cannot be gripped or the rubber There is a problem that a situation occurs in which the rubber breaks at the grip portions on both sides of the metal core and the core metal cannot be separated.

  According to the method and apparatus described in Patent Document 2, since the rubber is heated for rubber separation as in Patent Document 1, the rubber becomes soft as in Patent Document 1, so that the rubber is separated. In addition, the rubber crawler is separated by passing it through a wedge-shaped separation device, and since the cutting is only on the ground side from the cored metal buried portion, the rubber may not be completely separated.

  According to the method and apparatus described in Patent Document 3, the cored bar is pushed out from the grounding side by a punching device, so that the rubber in the buried part of the cored bar is separated while remaining attached to the cored bar, and the separation is insufficient. There is a problem.

First, in the preparation stage, as shown in FIG. 7A, the hydraulic cylinder 17 is contracted to raise the clamp 16, and the hydraulic cylinder 10 is contracted. Then, the rubber crawler 1 is manually set across the mounting table 7 and the movable frame 9. At this time, the gap (hole) 1 d of the rubber crawler 1 is fitted into the claw 15 and set.

  Next, as shown in FIG. 7 (B), the hydraulic cylinder 17 is extended and sandwiched between the mounting table 7 and the cored bar holding part 16b of the clamp 16 so as to surround one protruding part 1c of the corresponding cored bar 1b. Then, one side of the rubber crawler 1 is held.

  Next, as shown in FIG. 7C, by extending the hydraulic cylinder 10, the movable frame 9 and the claw 15 integrated therewith are moved in the short direction of the rubber crawler 1, that is, in the direction away from the clamp 16. Then, the rubber 1a on the other side that is not pressed and held by the clamp 16 of the rubber crawler 1 is torn off and separated.

  Next, as shown in FIG. 7D, the hydraulic cylinder 17 is contracted to pull up the clamp 16, and the hydraulic cylinder 10 is contracted to return the movable frame 9 and the claw 15 to their original positions. Then, as shown in FIG. 8A, the rubber crawler 1 from which the half of the rubber 1a is separated is reversed, and a claw 15 is inserted into the gap between the core bars 1b and set on the mounting table 7 and the movable frame 9. To do. As shown in FIG. 8B, the hydraulic cylinder 17 is extended and sandwiched between the mounting table 7 and the cored bar holding part 16a of the clamp 16 so as to surround the other protruding part 1c of the corresponding cored bar 1b. The other side of the rubber crawler 1 is held.

  At this time, the part from which the rubber 1 a has already been removed is placed on the mounting table 7, and the part from which the rubber 1 a remains is placed on the movable frame 9. In this state, rubber is removed from the clamp 16 side of the rubber crawler 1, so that the clamp 16 side is lowered as indicated by an arrow 40 and the opposite side (non-holding side) is raised as indicated by an arrow 41, but Since the grip 15a is provided, the grip 15a presses the upper surface of the rubber 1a to prevent the rubber crawler 1 from floating, and the rubber crawler 1 is prevented from being detached from the claw 15.

  Next, as shown in FIG. 8C, the hydraulic cylinder 10 is extended to separate the remaining half of the rubber crawler 1 from the core metal 1b. Thereafter, as shown in FIG. 8D, the hydraulic cylinder 17 is contracted to raise the clamp 16 and take out the metal core 1b.

  Thus, in this embodiment, the metal core 1b portion is held by the clamp 16, and the claw 15 inserted into the gap 1d of the rubber crawler 1 is hydraulically moved together with the movable frame 9 without heating the rubber 1a portion. Since the rubber 1a is moved by the cylinder 10, the half of the rubber 1a and the remaining rubber 1a can be separated reliably and easily from the cored bar 1b without extending the rubber 1a.

  Further, in this embodiment, as shown in FIGS. 2 and 3, the rubber crawler 1 is preferably divided into three or more, and the rubber crawler 1 is formed into a short strip shape and separated from the core metal 1b. The length of the rubber crawler 1 when separating from 1b is shortened, the scale of the dismantling device can be reduced, and the implementation becomes easy.

  In this embodiment, since the grip 15a protruding in the advancing direction at the time of separation is provided on the upper portion of the claw 15, when the claw 15 is moved and the rubber 1a is separated from the core metal 1b by half, the grip 15a is applied to the upper surface of the rubber 1a, and the rubber can be reliably separated without the rubber 1a coming off.

Reference numeral 23b denotes a protruding portion provided on both sides of the claw 23 with the tip protruding in an arc shape. The protruding portion 23a abuts against the opposing surface of the core metal holding portion 21c of the clamp 21 so that the interval between the core metal holding portions 21c is increased. It plays the role of holding properly (that is, making the cored bar holding part 21c correspond to the position of the protruding part 1c of the cored bar 1b) and smoothing the sliding of the clamp 21 and the claw 23.

  As described above, the plurality of core metal holding portions 21c provided in the clamp 21 corresponding to the core metal 1b are movable in the longitudinal direction, and the plurality of claws 23 provided in the movable frame 22 are also movable in the longitudinal direction. Since the portion 21c and the claw 23 can be moved according to the interval between the core bars 1b of the rubber crawler 1, a plurality of types of rubber crawlers 1 having different sizes can be connected to one unit without replacing the clamp 21 and the movable frame 22. It can be disassembled with a dismantling device.
