Description

Technical Field

[0001] The present application relates to the technical field of cable pay-off angle pulleys, and in particular to a cable pay-off angle pulley structure. Background Art

[0002] A cable is a device for transmitting electrical energy or signals, usually composed of several or several groups of conductors. Cables and wires are generally composed of three components: a core wire, an insulating sheath, and a protective outer sheath (except for bare wires). Cables are usually made up of multiple wires bundled together, and their structure is relatively complex. Each core is insulated from each other, and an insulating protective layer is added on the outside. Cables have higher efficiency and stronger anti-interference ability when transmitting electrical energy or signals. Due to their complex structure and strong transmission capacity, cables are usually used in high-voltage power transmission, communication, data transmission and other fields.

[0003] During the cable laying process, when the cable needs to pass through a corner, a simple fixed bracket or ordinary pulley is usually used to support the cable. Although these methods can achieve the turning of the cable, they often have large friction resistance and easily cause the cable sheath to wear, affecting construction efficiency and cable service life.

[0004] Currently, a common solution is to install a fixed single pulley at the corner, and the cable is turned through the pulley. However, pulleys with this structure often cannot adapt to the requirements of turning at different angles, and the contact area between the pulley and the cable is limited, resulting in greater friction.

[0005] Therefore, the pulley structure of the prior art lacks flexibility and cannot be well adapted to the needs of the construction site. At the same time, the contact mode between the pulley and the cable easily causes wear and tear, which is not conducive to long-term use.

[0006] To this end, the present application proposes a cable pay-off angle pulley structure. Utility Model Content

[0007] The present application proposes a cable-releasing corner pulley structure to solve the problems raised in the above-mentioned background technology; the structural design, through the adjustable structure of the corner frame, realizes flexible adaptation to different angle requirements, the design of the pulley assembly increases the contact area with the cable, effectively reduces the friction resistance, and the precise control function of the adjustment mechanism ensures the accuracy of the opening and closing angle of the corner frame. The surfaces of the first pulley and the second pulley are both wear-resistant treated to extend the service life of the device. By replacing the pulley material, the friction resistance and corrosion resistance of the device are further improved, which greatly improves the practicality of the device.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0032] Reference Figure 1-3 A cable pay-off angle pulley structure includes a first angle frame 1, a second angle frame 2, a first pulley 3, a second pulley 4 and an adjustment mechanism 17. The first pulley 3 and the second pulley 4 are rotatably connected between the first angle frame 1 and the second angle frame 2. The surfaces of the first pulley 3 and the second pulley 4 are both provided with grooves 5.

[0033] An adjusting mechanism 17 is provided between the first corner frame 1 and the second corner frame 2. The adjusting mechanism 17 includes a first connecting plate 7, a second connecting plate 8 and a connecting rod 9. The first connecting plate 7 and the second connecting plate 8 are respectively fixedly connected to the first corner frame 1 and the second corner frame 2, and a connecting rod 9 is provided inside the first connecting plate 7 and the second connecting plate 8; by setting the first connecting plate 7 and the second connecting plate 8 and the connecting rod 9, the first connecting plate 7 and the second connecting plate 8 are respectively connected to the first corner frame 1 and the second corner frame 2 by welding, so that the fixing effect is good and the stability is strong, thereby improving the practicality of the device. Through the adjustable structure of the corner frame, flexible adaptation to different rotation angle requirements is achieved. The design of the pulley assembly increases the contact area with the cable and effectively reduces the friction resistance. The precise control function of the adjusting mechanism 17 ensures the accuracy of the opening and closing angle of the corner frame. The surfaces of the first pulley 3 and the second pulley 4 are both wear-resistant treated to extend the service life of the device. The friction resistance and corrosion resistance of the device are further improved by replacing the pulley material.

[0034] One end of the connecting rod 9 is fixedly connected to the first limit plate 11, and the other end of the connecting rod 9 is fixedly connected to the second limit plate 12; by setting the first limit plate 11 and the second limit plate 12, it is used to prevent the two ends of the connecting rod 9 from being separated from the first connecting plate 7 and the second connecting plate 8, ensuring the connectivity during use and not easy to loosen, thereby improving the practicality of the device.

[0035] The middle section of the connecting rod 9 is provided with an anti-slip texture 10, which is an uneven texture. By providing the anti-slip texture 10 and coating the middle section of the connecting rod 9 with the anti-slip texture 10, the friction force is increased, the anti-slip performance is improved, and the practicality of the device is improved.

[0036] A first thread 13 is provided inside the first connecting plate 7, and a second thread 14 is provided on the outside of the connecting rod 9 and on one side of the anti-slip texture 10, and one end of the connecting rod 9 is threadedly connected to the first connecting plate 7 through the first thread 13 and the second thread 14; by rotating the connecting rod 9 in the forward direction, at this time, the first thread 13 inside the first connecting plate 7 and the second thread 14 at one end of the connecting rod 9 cooperate with each other, prompting the first corner frame 1 to move toward the second corner frame 2, thereby improving the practicality of the device.

[0037] A third thread 15 is provided inside the second connecting plate 8, and a fourth thread 16 is provided on the outside of the connecting rod 9 and on the side of the anti-slip texture 10 away from the second thread 14, and the other end of the connecting rod 9 is threadedly connected to the second connecting plate 8 through the third thread 15 and the fourth thread 16; by rotating the connecting rod 9 forward, the third thread 15 in the second connecting plate 8 and the fourth thread 16 at the other end of the connecting rod 9 cooperate with each other, so that the second corner frame 2 is moved toward the first corner frame 1, thereby achieving flexible adaptation to different corner requirements, and being used to adjust the opening and closing angles of the first corner frame 1 and the second corner frame 2. The precise control function ensures the accuracy of the opening and closing angles of the corner frames, thereby improving the practicality of the device.

[0038] The first thread 13 and the second thread 14 are arranged opposite to the third thread 15 and the fourth thread 16; by setting the first thread 13, the second thread 14, the third thread 15 and the fourth thread 16, nut-type or screw-type thread grinding tools made of softer materials such as cast iron are used to perform forward and reverse rotation grinding on the parts of the processed threads on the workpiece where there is a pitch error, so as to improve the pitch accuracy, thereby enhancing the practicality of the device.

[0039] The bottom ends of the first corner frame 1 and the second corner frame 2 are respectively fixedly connected to two supporting legs 6, and each supporting leg 6 is connected by a welding process; by setting the supporting legs 6 and welding the supporting legs 6 at the bottom ends of the first corner frame 1 and the second corner frame 2, the contact between the first corner frame 1 and the second corner frame 2 and the ground is pulled apart, ensuring the smooth rotation of the first pulley 3 and the second pulley 4, thereby improving the practicality of the device.

[0040] Working principle: A first pulley 3 and a second pulley 4 are set between the first corner frame 1 and the second corner frame 2. The two rolling pulleys are placed parallel to the two ends of the device to support and guide the travel direction of the cable. An adjustment mechanism 17 is added between the first corner frame 1 and the second corner frame 2. The adjustment mechanism 17 is connected between the first corner frame 1 and the second corner frame 2 to adjust the opening and closing angles of the first corner frame 1 and the second corner frame 2. The surfaces of the first pulley 3 and the second pulley 4 are provided with grooves 5 to increase the contact area with the cable and reduce friction.

[0041] The specific use of the adjustment mechanism 17 is to hold the anti-slip texture 10 part of the connecting rod 9 with the palm of your hand, and then rotate the connecting rod 9 in the forward direction. At this time, the first thread 13 inside the first connecting plate 7 and the second thread 14 at one end of the connecting rod 9 cooperate with each other, prompting the first corner frame 1 to move toward the second corner frame 2. At the same time, because the threads of the third thread 15 and the fourth thread 16 are opposite to the first thread 13 and the second thread 14, the third thread 15 in the second connecting plate 8 and the fourth thread 16 at the other end of the connecting rod 9 cooperate with each other, prompting the second corner frame 2 to move toward the first corner frame 1. In this way, flexible adaptation to different corner requirements is achieved, which is used to adjust the opening and closing angles of the first corner frame 1 and the second corner frame 2. The precise control function ensures the accuracy of the opening and closing angles of the corner frames.

[0042] This structural design, through the adjustable structure of the corner frame, achieves flexible adaptation to different turning angle requirements. The design of the pulley assembly increases the contact area with the cable, effectively reducing friction resistance. The precise control function of the adjustment mechanism 17 ensures the accuracy of the opening and closing angle of the corner frame. The surfaces of the first pulley 3 and the second pulley 4 are both wear-resistant to extend the service life of the device. The friction resistance and corrosion resistance of the device are further improved by replacing the pulley material.

[0043] The above are only preferred specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present application within the technical scope disclosed in the present application, and they should be covered by the protection scope of the present application.
