Description

[Detailed explanation of the idea]

0001 [Purpose of invention]

0002

[Industrial application field]

This invention is a cable rack for storing thin cables such as instrumentation cables and control cables. This invention relates to curved rollers for cable extension used when extending cables.

0003

[Conventional technology]

When extending thin cables by machine, it is not effective to extend the cables one by one. Because of the low efficiency, sometimes a construction method is adopted in which multiple cables are extended together. . For example, a single messenger wire is placed in advance on a cable rack installed in the wire passageway. In addition to extending the road endlessly along the road, it is also possible to run on it. child Connect two or three cables to one messenger wire. There is a construction method.

0004 In this method, most of the tension during wire stretching is applied to the messenger wire, but The passageway has straight sections and curved sections, so there are fluctuations, especially at curved sections. Increase rapidly.

[0005] In order to reduce the tension at the bend as much as possible and improve work efficiency, use 3 to 4 rods. Use a curved roller for cable extension, which is made by arranging rollers curved along the curve. is desirable.

[0006] Conventional curve rollers of this type have three to four rollers between a pair of curved frames. Some rollers are arranged in a curved shape. If you use this, please extend the line. Place it along the cable rack to be installed and secure it with bolts. Ru.

[0007]

[Problem that the idea aims to solve]

However, conventional curved rollers for cable extensions only allow cables to be tightened by bolts. Since it is fixed directly to the bull rack or to an auxiliary member on its side, There was an inconvenience in that it took a considerable amount of time and effort to install.

[0008] The present invention was made to solve the disadvantages of the conventional example described above, and it can be done in a short time. To provide a curved roller for cable extension that can be fixed to a cable rack. With the goal.

[0009] [Structure of the idea]

0010

[Means to solve the problem]

The curved roller for cable extension of the present invention includes a pair of frames and the pair of frames. A small piece of paper is rotatably supported between the arms, with each axis being approximately parallel to each other and positioned on a curved line. at least three rollers and at least three rollers fixedly attached to the lower outer surface of one of the frames. Both have two fixed seats and at least Two fixed seats and a one-touch button that is removably installed on the lower or upper fixed seat. The present invention is characterized in that it is equipped with a double-sided clamp.

[0011]

[Effect]

The curve roller for cable extension of this invention is installed on the main girder of the cable rack at the bending point. It is placed and fixed with one touch using the one-touch clamp. The fixed seat is Provides a seat for attaching touch-type clamps and prevents bends in cable racks. Its role is to determine the position when installing it in a certain location.

0012

【Example】

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

[0013] The curved roller shown in the figure includes a pair of frames 1a and 1b.

[0014] The frames 1a and 1b are each curved in an arc shape and have circular ends. They are shaped like an oval and are placed opposite each other. Between the pair of frames 1a and 1b, there are three Rollers 2a, 2b, and 2c are rotatably supported. Rollers 2a, 2b, 2c The axes of the frames 1a and 1b are located on a curve C that is substantially parallel to each other and along the arc shape of the frames 1a and 1b. It is located in

[0015] Two fixed seats 3a and 3b are fixed to the lower part of the outer surface of one frame 1a. There is. Furthermore, two fixed seats 4a and 4b are fixedly installed above the outer surface of the other frame. It is. These fixed seats 3a, 3b and 4a, 4b have a cylindrical shape. . The one-touch clamp 5 is attached to and detached from the upper fixed seats 4a and 4b by tightening the bolts. possible. This one-touch clamp 5 has bolts on the fixed seats 4a and 4b. A main body 7 is fixed by a bolt 6, and a pusher 8 is attached to the main body 7 at one end and has a presser 8 at the other end. a pressing part 9 having a pressing part 9, and an operating part having one end pivoted to the main body 7 and a lever 10 at the other end By rotating the lever 10, the presser 8 is moved in its axial direction. It moves back and forth in the direction.

[0016] The curved roller of this invention constructed in this way is used at the bending point of the cable rack. When it is installed, it is installed as shown in Figure 3. In other words, in Figure 3, four cars The brackets are placed at two locations 13 at the beginning of the bend of the main girder at the bend point of the cable rack 12. a, 13b and two locations 14a, 14b at the end of the bend, respectively. Start of bend As shown in FIG. 5, the messenger wire 15 And the cable 16 latched to the messenger wire 15 is connected to the cable rack 12 4, and at two locations 14a and 14b at the end of the bend, as shown in FIG. Messenger wire 15 and cable 16 are placed on top of cable rack 12 so that be allowed to pass by the side. In addition, attach the curved roller to the main girder of cable rack 12. In this case, the fixed seats 4a and 4b are used as seats and used for positioning.

[0017] As can be seen from FIGS. 4 and 5, there are two locations at the beginning of the bend of the cable rack 12. Curved roller one-touch clamps 5 located at 13a and 13b and the end of the bend Curved roller one-touch clamps 5 located at two locations 14a and 14b of the section. , the upper and lower positions on both outer surfaces of the pair of frames 1a and 1b are opposite to each other. ing. Therefore, the curved roller of the present invention has a one-touch clamp 5 on one side. The one fixed to the upper fixing seat on the outer surface of the frame, and the one fixed to the upper fixed seat on the outer surface of the other frame. Those fixed to lower fixed seats are used. One-touch clamp 5 Simply change the body of the curved roller from one frame to the other. It can be used both at the beginning of the bend and at the end of the bend.

[0018]

[Effect of the idea]

As mentioned above, the curved roller of this invention uses a fixed seat at the bending point of the cable rack to position it. It is placed while positioning, and is fixed with a single touch using a one-touch clamp. This allows for steady and easy installation. In addition, the curved roller of this invention You can easily bend the cable rack by simply replacing the one-touch clamp with the other fixed seat. It can be used both at the beginning of the bend and at the end of the bend.
