作業用デツキである。 Conventionally, when excavating with a shield excavator,
Various excavation methods are used in response to changes in the strata (such as when a hard rock is hit or when boulders come out). For example, a breaker is used in a bucket-type shield excavator 1 with a labor-saving machine as shown in FIGS. 1 and 2. That is, a bucket 3 is attached to the tip of a swinging arm 2 provided inside the shield main body 1a so as to be able to swing horizontally and vertically.
It was replaced with a breaker and excavation was performed using the breaker. In the figure, reference numeral 4 designates a deck for excavation work that is provided above the swing arm 2 and is movable in the front and rear directions.

Inside the main body of the shield excavator with a bucket-type labor-saving machine, there is a swinging arm 13 that is supported so as to be able to swing vertically and horizontally and has a bucket 12 at its tip, and above the swinging arm 13 there is a cylinder device that extends in the front-rear direction A. A movable deck 15 is provided which is movable by means of 14. The swinging arm 13 in the vertical direction B is controlled by the cylinder device 1.
6, and the swinging (turning) in the left and right direction is performed via a shaft 17 connected to the other end. A mounting bracket 19 for mounting a breaker 18 is protruded from the top surface of the bucket 12, and is detachable from the breaker 18 via a bolt body 20. In addition, the floor 15 of the movable deck 15
a On the bottom surface, there is a storage bracket 2 for the breaker 18.
1 is provided protrudingly, through holes 22 and 23 are formed in the breaker 18 and the storage bracket 21, respectively, and a rod 24, which is an example of an engaging means, is formed in the breaker 18 and the storage bracket 21.
is connected to the cylinder device 25 and the through hole 2
2 and 23. In addition, 2
6 and 27 are cushioning rubber plates.

必要としない。 According to the above structure, when the breaker 18 is required, the breaker 18 can be attached to the mounting bracket 19 on the upper surface of the bucket 12 with the bolt body 20, and the breaker 18 can be used for excavation (solid line position in FIG. 3). When storing the breaker 18, after confirming that the movable deck 15 is in the retracted position, the swinging arm 13 is swung upward to connect the through hole 22 of the breaker 18 and the through hole 23 of the storage bracket 21. Match. Then, the rod 24 is moved into both through holes 2 by the cylinder device 25.
2 and 23, the breaker 18 can be simply and easily stored in the movable deck 15 (the position indicated by the imaginary line in FIG. 3). In this way, when the breaker 18 is required, it is only necessary to attach the breaker 18 to the top surface of the bucket cart 12, and when the breaker 18 is removed and stored, it can be stored as is in the upper movable deck 15, so it is not necessary to install the breaker 18 on the upper surface of the bucket 12. There is no need to replace the bucket 12 and breaker 18 as in the case of the above.
