[0033] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.
[0034] See figure 1 , An anti-breaking device for cables and vehicles, comprising a cylinder body 6 that can accommodate cables. One end of the cylinder body 6 is provided with a support plate 1, a bearing seat 2 is provided on the support plate 1, and a bearing 3 is installed in the bearing seat 2 , Also includes the shaft 4 matched with the bearing 3, such as image 3 As shown, the shaft 4 is provided with a channel communicating with the cylinder 6;
[0035] The side of the cylinder 6 is also provided with a cable steel pipe 7 communicating with the cylinder 6, and the passage of the shaft 4, the cylinder 6 and the cable steel pipe 7 constitute a passage for the cable to pass through.
[0036] The cable steel pipe 7 is provided with a fixing plate 8 for pressing the cable, and the cable steel pipe 7 is provided with an adjusting mechanism for adjusting the fixing plate 8. Such as figure 2 As shown, the adjusting mechanism includes an adjusting bolt 9 which is threadedly connected with the cable steel pipe 7, and the end of the adjusting bolt 9 is in contact with the fixing plate 8.
[0037] The supporting plate 1 closes one end of the cylinder 6, and a dustproof plate 5 is also provided to close the other end of the cylinder 6. Both the shaft 4 and the cylinder 6 are made of metal.
[0038] A method for using the above-mentioned cable vehicle cable anti-breaking device includes the following steps:
[0039] 1) Pass one end of the cable into the cylinder 6 through the through hole of the shaft 4, and then leave a certain amount of cable in the cylinder 6;
[0040] 2) Pass the cable out of the cable steel pipe 7,
[0041] 3) Adjust the adjusting bolt 9 to make the fixing plate 8 compress the cable,
[0042] 4) Connect the cable to the cable car body.
[0043] When the device is assembled and used, the cable is first inserted through the shaft 4, passed through the cylinder and the cable steel pipe 7, then installed the dustproof plate 5, tightened the adjusting bolt 9, and finally connected with the cable car body. In the process of movement, because the cable car usually reciprocates linearly along the steel rail on a plane, the rotating part of the cable anti-breaking mechanism includes the bearing seat 2, the transparent cover, the support plate 1, the cylinder, the cable steel pipe 7, etc. , This part all rotates around the axis 4, and its swing angle is less than 180°. At the same time, when the cable takes the axis as the reference frame, it can also be regarded as swinging along the axis. After changing the movement of the cable, the fixed end is prevented from being damaged due to frequent reciprocating movement.
[0044] After adopting the above-mentioned structure, 1. The condition that the part of the cable close to the cable vehicle is exposed to the outside can be changed, that is, the cable can be effectively protected by this mechanism. During the movement of the cable vehicle, even if molten steel splashes, it will only splash on the protective mechanism and will not burn the cable; or if the scrap steel falls from the basket car and hits the protective mechanism, it will not cause damage to the cable.
[0045] 2. The cable can slide inside the shaft 4 along the inner diameter of the shaft, or it can rotate with the shaft 4 around the support plate 1, instead of fatigue damage to the cable due to frequent reciprocating movement at the fixed end of the cable at this stage. Reduce axial and circumferential fatigue damage and extend the service life of the mechanism.
[0046] 3. There will be a large space in the cylinder 6, and a certain length of extra cables can be put in this space. When the cable is under tension, a surplus cable is provided to ensure that the internal cable will not be broken. This part of the cable can also be used for measurement during scheduled repairs, that is, regularly open the dust cover to measure the length of the internal cable to determine whether the bolt is loose.
[0047] 4. In order to make the cable extend the "dangerous distance", it can be solved by adjusting the designed length of the shaft 4 and the cable steel pipe 7 according to the actual situation of the site.
[0048] 5. The cross-section of common cables is mostly round, but there are also cables with other shapes, such as flat cables. In order to meet the needs of different cables, it can be solved by changing the design of shaft 4 and cable steel pipe 7.
[0049] If the cable is a flat cable: when the longest side of the cable section is less than 50mm, press image 3 Design, that is, the inner hole is directly processed into the shape of a flat cable; if the longest side is greater than 50mm, press Figure 4 design, Figure 4 The middle bracket is welded with steel plate, as detailed as Image 6 Shown. In addition, for flat cables with the longest side greater than 50mm, you can also press Figure 5 Design, the internal grid part is filled with asbestos.
[0050] The cable steel pipe 7 is designed in the shape of the cable: if the cable section is round, the fixing plate 8 is designed as a semicircle, and the cable steel pipe 7 is designed as a circle; if the cable is a flat cable, the fixing plate 8 is made of flat steel Instead, the cable steel pipe 7 is welded with a steel plate into a flat cable shape. However, in either case, the internal space shape and size must be larger than the flat cable outline size.
[0051] 6. There are two schemes for the connection between the mechanism and the car body. One is directly welded to the car body, and four ribs are used to strengthen the connection with the car body in a "cross arrangement" manner, such as Figure 7 , The other is flange connection, such as Figure 8. Figure 7 The shape of cable products suitable for use in the market is relatively fixed, Figure 8 There are many types of applicable cable products, and it is relatively easy to replace this kind of cable, just replace Figure 8 The flanged part of the middle and right side is sufficient, eliminating the need for welding to the car body again.
[0052] 7. The gravity of the cable anti-breaking mechanism and the gravity and tension of the cable will eventually act on the shaft 4. The main torque generated on the shaft 4 is followed by the bending moment, so choose a material with higher strength such as 40Cr.
[0053] 8. The inner hole near the shaft 4 of the through-cover end must be rounded to prevent the edges from cutting the cable.
[0054] 9. Bearing 3 can be refueled by designing and installing an oil cup to extend the service life of bearing 3.
[0055] 10. Install a dust-proof plate 5 on the outside of the cylinder to prevent the spilled high-temperature liquid from flowing into the cylinder and burn the cable, and at the same time play a role in preventing dust in the harsh environment.
[0056] 11. A felt ring oil seal is installed between the shaft 4 and the bearing seat 2 and the end cover for sealing to prevent dust from entering and protect the bearing 3.
[0057] The present invention has been exemplarily described above in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited by the above methods, as long as the method concept and technical solution of the present invention are used for various insubstantial improvements or without improvements. Application of the concept and technical scheme of the present invention to other occasions directly falls within the protection scope of the present invention.
