る。"Prior Art" Conventionally, a fixing fitting was attached to the rail in order to fix the connecting fitting for connecting the long rail unloading device to the rail to the rail. Conventional fixing fittings have a rail head insertion groove in the main body, the lower facing surfaces of the groove protrude in opposite directions to form a rail head engaging part, and a key is inserted between the groove and the rail head. (Wedge) A was inserted by impact with a hammer to fix the main body to the rail (the state is shown in Fig. 5). Also, the rail head is held between the left and right sides by a pair of frames, and in this state, the above-mentioned pair of frames are connected with bolts, and a shoe or key is pressed onto the top surface of the rail head by operating a lever or the like, and the rail is assembled. There are those that are attached to the head (for example, Japanese Utility Model Publication No. 2-3008,
Publication No. 46-30650, etc.). However, the former method poses a safety problem as there is a risk of damage to the rail due to a hitting error and a risk of bruises to the worker himself/herself. In addition, the key extraction work is carried out late at night on-site, causing a noise problem for the hitter. Moreover, the latter has the disadvantage that its structure is complicated, making it inconvenient to store and handle the device body, and also requiring time and trouble to attach it to the rail head.

によつて構成される。``Means for Solving the Problems'' In order to achieve the above object, this proposal forms a rail head insertion groove in the lower part of the main body, and makes the lower end facing surface of the groove protrude in the opposite direction to insert the rail head engaging part. A rail head press member is arranged inside the groove so as to be slidable up and down in the vertical direction along the groove and fixed in the rotating direction, and the rail head member is placed in the groove from the upper surface of the main body toward the lower part of the main body. A through hole is drilled to open, a downward step is formed inside the through hole, a screw hole corresponding to the upper end opening of the through hole is bored inside the press material, and the screw hole is fitted into the through hole. Screw the lower part of the combined bolt into the screw hole,
A friction material is disposed on the lower surface of the pusher, and the upper surface of the flange formed on the bolt faces the downward step, and a thrust bearing is interposed and engaged therebetween, and the bolt head of the bolt is inserted into the through hole. It consists of a fixture for handling long rails that faces the upper end opening of the rail.

The upper surface of the head 2 can be brought into contact with the lower surface of the friction material 9, and the rail head press material 7 can be placed on the upper surface. In this state, when the bolt head 14 appearing at the upper end opening 5' of the upper surface of the main body 1 is turned with a wrench, the pusher member 7 screwed into the lower part of the bolt 10 is pushed through the friction material 9 to the rail head. The bolt 10 is fixed on the upper surface of the section 2 and is raised to the flange 1.
The upper surface of 1 is pressed against the downward step 6 via the thrust bearing 12, and the reaction force presses the friction material 9 and the rail head 2 between the pusher 7 and the engaging parts 4, 4, and the rail is closed. The above main body can be fixed to. When separating, the bolt head 14 is rotated with a wrench in the opposite direction to the above-mentioned direction, thereby breaking the pressure contact between the press member 7 and the friction material 9 and the upper surface of the head 2, and allowing the main body 1 to slide. Can be removed from the rail.

A through hole 5 is bored through the bottom surface of the groove 3 and the top surface of the main body 1, and a circular downward step 6 is formed inside the through hole 5 to enlarge the inner diameter below the step. A rail head press member 7 is disposed on the bottom surface of the groove 3 and is slidable up and down, and is fitted into the groove 3 and fixed in the rotating direction. Matching threads 8 are bored in the pusher 7, and a friction material 9 is provided on the lower surface of the pusher 7. Then, the lower male threaded part of the bolt 10 inserted into the opening 5' is screwed into the threaded hole 8, and the upper surface of the flange 11 provided on the bolt 10 faces the downward step 6, and the thrust bearing 1
2 are interposed and engaged. 13 in the figure
1 is a hub bolt screw hole for preventing the bolt 10 from falling, 14 is a bolt head, and 15 is a hexagonal recess.

Components for tightening such as the rail head press member 7 are arranged inside the main body 1, and there are no protrusions on the outside of the main body 1, and the main body 1 itself can be configured in a simple shape. It can be downsized and the main body 1 itself can be easily stored and handled. Furthermore, since the main body 1 has a simple shape, there is more freedom in handling it when moving the rail by engaging a hook or the like with the main body 1 while it is attached to a rail, compared to conventional products. However, the functionality will not deteriorate. In addition, the bolt head 14 appearing on the top surface of the main body 1 can be smoothly rotated in forward and reverse directions via the thrust bearing 12, and the main body 1 can be fixed to or separated from the rail head 2 by only this rotation, and striking work can be performed. Since this is not necessary, the main body 1 can be safely attached to and detached from the rail without any damage to the rail and there is no danger to the operator, and the attaching and detaching work can be carried out quietly without noise.
