雑になるといつた問題があつた。 However, when using the above-mentioned device to bolt flanges or metal fittings installed on the ceiling or floor of a tunnel or passageway with a low ceiling (such as a tunnel with a ceiling high enough for a person to bend down to pass through). The problem is that it is necessary to move the equipment away from the ceiling or floor by the length of the motor shaft, but if you support the equipment while working in this state, your working posture becomes extremely cramped and the work becomes complicated. It was hot.

するといつた弱点もあつた。 However, when the above-mentioned bolt tightening work requires the tightening of many types of bolts and nuts of different sizes and shapes, when the above-mentioned device is used, the bolts and nuts are tightened.
Depending on the size and shape of the nut, it is necessary to replace the above-mentioned device with sockets of different sizes and shapes, which reduces the workability of bolting.

になつている。 On the other hand, four through holes 1f having the same diameter are formed at 90° intervals in each of the peripheral walls 1d and 1e near the openings on both sides of the rotating shaft 1. In the opening of the engagement hole 1a on the bearing 4a side, there is a cap-shaped socket 20 formed on one side with an opening hole 20a into which a nut or the like is fitted, and on the other side (bottom outer surface side) of the socket 20. The prismatic protrusion 20b formed in the above is fitted into one opening of the engagement hole 1a, and the mounting pin 21 is inserted into the attachment hole 20c formed at the base of the protrusion 20b and the pair of insertion holes 1f, 1f. is installed by inserting it. In addition, the bearing 4a has
The receiving cylinder 22 is fitted with a bolt-shaped fixing member 23 screwed into a screw hole at the end of its outer peripheral wall in contact with the outer periphery of the bearing 4a, and the outer peripheral wall covers the socket 20. Furthermore, a reaction force receiver 22a is provided protruding from the outer peripheral wall of the receiver tube 22. 2 is a second socket in which an opening hole 24a smaller than the opening hole 20a of the first socket 20 is formed, and this second socket 24 is approximately the same as the first socket 20. It has a shape that allows it to be attached to the rotating shaft 1 in the same manner as the first socket 20 using the convex portion 24b and attachment hole 20c.

や金具はボルト止めされる。 The device configured as described above can be used to tighten bolts and nuts on flanges and metal fittings installed on ceilings and floors in narrow tunnels and passageways (tunnels with ceilings high enough for people to bend down to pass through). To turn the bolt, first fit the opening hole 20a of the socket 20 at one end of the support frames 4, 5 into the nut (or the head of the bolt) and turn on the switch 18.
When the switch 18 is turned on, the control device alternately sends pressure oil to the hydraulic cylinders 11 and 12 via the oil pipe, which causes the rods 11a and 12a to
move back and forth in conjunction. When the rods 11a and 12a reciprocate, the spanner arm 3 reciprocates around the rotating shaft 1, and as a result of this rotation, the rotating shaft 1 is intermittently rotated around its axis by the swinging arm 6. As a result, the socket 20 is turned with a nut, and the flanges and fittings are bolted.

First, rotate the fixing member 23 to loosen it, and then
Remove the receiving tube 22 from the
is pulled out from the insertion hole 1f and the attachment hole 20c, and the socket 20 is removed from the opening of the engagement hole 1a on the bearing 4a side. Then, the convex portion 20b of the socket 20
into the opening of the engagement hole 1a on the bearing 5a side,
The mounting pin 21 is inserted into the insertion hole 1f and the mounting hole 20c, and the receiving cylinder 22 is fitted into the bearing 5a, and the receiving cylinder 22 is fixed to the bearing 5a by the fixing member 23. Then, in the same manner as above, switch 18 is turned on to rotate socket 20 and turn the nut. At this time, since the socket 20 rotates in the opposite direction to the above, the nut can be turned in the opposite direction. In addition, as mentioned above, connect socket 2 to the nut, etc.
0, the axis of the bolt and the support plates 4, 5 are orthogonal, so the support plates 4, 5 can be supported in a comfortable posture even during tightening work in tunnels etc. where the work space in the direction of the bolt axis is narrow. can.

By bringing the reaction force into contact with the reaction force receiver 22a, the reaction force can be received by the reaction force receiver 22a.

In addition to the sockets listed above, we have prepared a wide variety of sockets with opening holes (not shown) of various shapes and sizes, so that you can choose the shape or size of the bolt head or nut you are using. Replace and use as appropriate. This allows bolts and nuts of various shapes or sizes to be rotated simply by changing the socket.

It is also possible to configure so that the rotation direction of 1 changes.

め付け作業を行うことができる。 As explained above, in this invention, a rotating shaft equipped with a socket that fits into a nut, etc. is rotatably attached to one end of a support plate, and one end of a spanner arm is rotatable around the rotating shaft. A nut or the like is attached freely to the support plate, and the support plate is provided with a drive mechanism consisting of a hydraulic cylinder that is provided at the other end of the spanner arm in a direction perpendicular thereto, and that rotates the rotation shaft. In the tightening device, the rotary shaft is attached to the support plate with both ends disposed on both sides of the support plate, and the socket is selectively detachably attached to both ends of the rotary shaft, so that the socket can be replaced. Since the rotary shaft can be connected to the heads of nuts and bolts of various sizes, it is possible to tighten bolts and nuts of various shapes and sizes. Therefore, it is possible to easily and quickly turn and tighten various bolts and nuts of different sizes and shapes in a narrow tunnel or the like where the working space in the bolt axial direction is small by simply and quickly changing the socket. Furthermore, the drive mechanism uses a hydraulic cylinder to reciprocate the spanner arm around the rotation axis, that is, it combines the principles of a hydraulic cylinder and a lever, so the device can simply be held. It is possible to generate a large tightening torque with only a single bolt, and it can also handle bolts with a large tightening torque value.
The device can be made smaller and lighter, and its operability can be improved. Furthermore, since the hydraulic cylinder can be used as a handle, the device can be reliably held and subjected to reaction force, and tightening work can be performed reliably even in a narrow place with a small work space.
