保の点から問題があつた。 As construction progresses, the gate-type work machine moves along the rails laid next to the road, etc. At this time, the horizontal level of the rails is not constant, and there are differences in height. If there is, an uneven load will be placed on the legs brought to the low part of the rail. Conventionally, such abnormalities have been detected using a level meter, but this method does not allow accurate determination of how much unbalanced load is being applied to which leg. For this reason, even if it is possible to detect that an unbalanced load is being applied to the legs, it is difficult to detect how much more unbalanced load it can withstand, which poses a problem in terms of ensuring safety.

る。 Therefore, the present invention provides a gate-type working machine that solves these problems.The main feature of this invention is that a bearing supporting the appropriate axle is attached to the traveling device disposed at the lower end of each leg. A vertical load detection device that fits onto the axle is removably attached to the bearing with a bolt and nut, and the diameter of the axle through hole of the bearing is slightly larger than the diameter of the axle through hole of the vertical load detection device. In addition, by adjusting the relative position of the vertical load detecting device with respect to the bearing using the bolt and nut, the axle can be supported by the vertical load detecting device instead of the bearing. With this configuration, the vertical load detection device can accurately detect the unbalanced load applied to the leg via the axle, and accurately detect how much more unbalanced load the leg can withstand. It is something that can be done. Therefore, safety can be sufficiently ensured.

This prevents the vehicle from rolling horizontally. Axle through hole 6a of one bearing 6 facing vertical load detection device 11
The diameter of the axle is made larger than the diameter of the axle 8, thereby forming a slight gap α between the axle 8 and the axle through hole 6a. Also, strain gauge 13
The front and back sides of the sensor cancel each other's bending effects so that only vertical loads can be detected, and the sensor is attached in a position that is not affected by temperature changes. Furthermore, the strain gauge 13 forms a bridge circuit, and the output from that circuit is connected to an amplifier and an A/
The load value enters the processing device via the D converter and is configured so that the detected load value is displayed on a display (not shown) on the work machine main body 1. Also, the cell body 12

におこなうことができるものである。 The operation of the above configuration will be explained. The state shown in FIG. 3 is a state detected by the vertical load detection device 11, in which the vertical load of the leg portion 2 is directly applied to the axle shaft 8 via the other bearing 7, and the vertical load on one of the bearings 6,
It is connected to the axle 8 via the bolt 16, nut 17 and the vertical load detection device 11, so that the vertical load of the leg 2 is transferred to the vertical load detection device 11.
is detected and the load is displayed on the display. Therefore, the operator on the work machine main body 1 only has to run the traveling device 3 while watching the load displayed on the display to advance the work machine. and rail 9
When an uneven load is applied to the leg part 2 due to a difference in height, it is possible to immediately know the value of the uneven load, and also to know how close the uneven load value is to the maximum allowable load value. to accurately judge whether or not it is okay to run with the unbalanced load applied, or whether or not to immediately stop running and extend/contract the appropriate leg portions 2 to eliminate the unbalanced load. It is something that can be done.

なえばよい。 Next, if detection by the vertical load detection device 11 is not required, loosen the nut 17 and tighten one of the bearings 6.
It is sufficient that the vertical load detection device 11 is not subjected to any load by directly contacting the axle 8.
Furthermore, when you want to remove the vertical load detection device 11 for maintenance etc. of the vertical load detection device 11, remove the nut 17 and bolt 16,
What is necessary is to remove the key plate 18 bolted to the cell body 12, grasp the cell body 12, and remove it from the axle 8. After maintenance, when installing the vertical load detection device 11, the procedure may be reversed.
