(57) [Summary] [Purpose] Eliminate the work of carrying heavy objects such as bolt tensioning machines, and facilitate bolt tensioning operations. [Structure] A trolley that can travel on a rail, a bolt tensioner suspending arm that is mounted on the trolley, and a bolt tensioner that hangs on the arm via a spring are suspended via the spring. The feature is that the lowered bolt tensioning machine is pushed down and set at the bolt position to perform the tensioning work.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a rail fastening bolt tensioning trolley in which a bolt tensioning machine is hung on a trolley that can travel on rails so that the tensioning work of the rail fastening bolt can be performed efficiently.

[0002]

[Prior art]

 Conventionally, the bolts used to fasten rails to sleepers have been manually moved by manually carrying and moving the bolt tensioner, the power source engine, and the cord for supplying power from the power source to the bolt tensioner. I was going.

[0003]

[Problems to be solved by the device]

 In this way, the conventional work to relieve the rail fastening bolts has been performed manually, but the bolt retraction machine, the power supply engine, the power supply, etc. are heavy items, which makes them difficult to carry. Since the work is performed by the person bending over, the work efficiency was poor due to the severe work that hurt the waist and the like. The present invention is to solve the above problems, and to provide a rail fastening bolt tensioning trolley that eliminates the work of carrying heavy objects such as a tensioning machine and can easily perform the bolt tensioning work. With the goal.

[0004]

[Means for Solving the Problems]

 The rail fastening bolt tensioning trolley of the present invention comprises a trolley capable of traveling on rails, a bolt tensioning machine suspension arm mounted on the trolley, and a bolt tensioning arm hung on the arm via a spring. It is characterized in that it is equipped with a machine, and that the carriage is provided with a chair.

[0005]

[Action]

 The present invention attaches a bolt tensioning device suspension arm to a truck that can run on rails, attaches the tensioning device to the spring at its tip, and supplies all the equipment necessary for bolt tensioning work, such as power source engine and power source. The bolts are fastened in a comfortable position by moving them on the rails and sitting on a chair so that you do not need to carry heavy objects required for bolt tightening work. There is no fear of damaging the lower back and the work efficiency can be improved.

【Example】

 FIG. 1 is a side view of a rail fastening bolt tensioning trolley of the present invention, FIG. 2 is a plan view of a rail fastening bolt tensioning trolley, and FIG. 3 is a front view of a rail fastening bolt tensioning trolley. In the figure, 1 is a spring, 2 is a bolt tensioner, 3 is a foot rest, 4 is an insulating wheel, 5 is a chair, 6 is a light, 7 is an arm for suspending the bolt tensioner, 8 is a carrier, 9 is a trolley. Reference numeral 10 is a brake device, 11 is an axle, 12 is a support frame, and 13 is a receiving port.

In the plan view of FIG. 2, the carriage 9 can run on the rail by three wheels 4, and the wheels are insulated wheels such as rubber tires, which hinders train control. . Further, a loading platform 8 is provided on the axle 11 of the truck, and a chair 5 is provided on the support frame 12 at a position corresponding to one rail, and a footrest 3 is provided at one end of the support frame. Is provided. At one end of the supporting frame 12 provided with the footrest 3, a receiving port 13 into which the bolt tensioning device suspending arm 7 is inserted is provided.

As shown in FIG. 1 which is a side view seen from the direction A in FIG. 2, the bolt tensioner 2 is suspended from the bolt tensioner suspension arm 7 inserted in the receiving port 13 via the spring 1. The bolt tensioner 2 is provided with a handle 2a as shown in the front view of FIG. The seat 5 is provided with a light 6 for illuminating the track surface, and the front wheel 4 is provided with a brake device 10. Although not shown, the power supply engine, power supply and other devices necessary for tightening bolts are mounted on the carrier 8 of the carriage.

[0009] With such a configuration, when performing the bolt tensioning work, the user sits on the chair 5 of the carriage and suspends the bolt tensioner on the spring 1 attached to the bolt tensioner suspension arm 7. By holding the bundle 2a and pushing down the bolt tensioner to set the tip at the bolt position, the rail fastening bolt can be tensioned in an extremely comfortable position, even if it moves freely on the rail. It is possible to carry heavy objects manually.

[0010]

[Effect of device]

 As described above, according to the present invention, all the devices necessary for bolt tensioning work are placed on the trolley, moved on the rail, and the tensioner is attached to the spring attached to the bolt tensioner suspension arm to attach the tensioner. Since the bolts can be tightened in a comfortable position while sitting on a chair, it is not necessary to carry the power supply engine, power supply, cords, etc., and at the same time, there is no risk of injury to the waist and work efficiency is improved. Is possible.
