Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cable laying, in particular to a cable laying anti-cutting and anti-damage protective jacket. Background Art
[0002] In cable laying and traction operations, traditional cable traction sleeves usually directly drag the cable net and the cable body to move on the ground. This method has many shortcomings. First, the cable net and the cable body are prone to friction and collision with stones, sharp objects, etc. on the ground during the dragging process, which not only easily causes damage to the cable net, but also may cause damage to the cable body, affecting its performance and life. Secondly, due to the lack of effective support and friction reduction devices in the traditional traction method, the friction force during the traction process is relatively large, which not only increases the load of the traction equipment, but also reduces the traction efficiency. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model provides a cable laying anti-cut and anti-damage protective jacket, which has the advantages of anti-cut and anti-damage and improved traction efficiency, and solves the problems existing in the traditional cable traction jacket during the traction process.
[0004] The utility model provides the following technical solutions: a cable laying anti-cut and anti-damage protective jacket, comprising a cable sheath net, a guide wheel and a conical protective sleeve, the guide wheel being provided with three groups, a metal hollow tube being fixedly inserted in the middle of the guide wheel, an elastic steel cable being passed through the inside of the metal hollow tube, a positioning kit being movably sleeved on the outside of the elastic steel cable at both ends of the guide wheel, a fastener being passed through and threadedly connected at the middle of one end of the positioning kit, a rope loop being fixedly sleeved on the outside of the metal hollow tube at both ends close to the guide wheel, a pull rope being passed through and around the inside of the rope loop, and three groups of evenly distributed pull rings being fixedly connected to the conical protective sleeve near the front end, and the pull rope being fixedly connected to the pull ring at one end away from the rope loop.
[0005] Furthermore, the three groups of guide wheels are connected in series through elastic steel cables, and grip-type cable locks are provided at the head and tail of the elastic steel cables.
[0006] Furthermore, the cable body is sheathed inside the cable sheath net, and the three groups of guide wheels are evenly distributed on the outside of the cable body through the positioning kit.
[0007] Furthermore, the tail of the cable net extends between the guide wheel and the cable body.
[0008] Furthermore, a restraining piece is provided at the head of the cable net, and a connecting steel cable is fixedly connected to the middle of the front end of the conical protective sleeve, and the connecting steel cable is fixedly connected to the restraining piece.
[0009] Furthermore, a rope buckle is fixedly connected to the front end of the binding member.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] 1. Compared with the traditional cable traction sleeve, this technical solution can support the cable sleeve net and the cable body through the design of the guide wheel to play a protective role, avoiding damage caused by friction and collision with objects such as stones on the ground during traction. At the same time, the guide wheel is equipped with bearings inside that can rotate when subjected to tension. Compared with directly dragging the cable sleeve net and the cable body on the ground, it can effectively reduce friction, reduce the load of the traction equipment, and improve traction efficiency.

[0013] 3. At the same time, the guide wheel will be more closely attached to the cable net when being pulled, thereby improving the fitting effect between the rear end of the cable net and the cable body, ensuring the traction effect of the cable net and effectively avoiding the occurrence of falling off.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-Figure 3 A cable laying anti-cut and anti-damage protective jacket, comprising a cable sheath 1, a guide wheel 2 and a conical protective sheath 10. The guide wheel 2 is provided with three groups. A metal hollow tube 3 is fixedly inserted in the middle of the guide wheel 2. An elastic steel cable 4 is passed through the inside of the metal hollow tube 3. The outer side of the elastic steel cable 4 is movably sleeved with a positioning kit 6 at both ends of the guide wheel 2. A fastener 7 is passed through and threadedly connected to the middle of one end of the positioning kit 6. A rope loop 8 is fixedly sleeved on the outer side of the metal hollow tube 3 at both ends near the guide wheel 2. The rope loop 8 The inside of each cable is wound with a draw rope 9, and the conical protective sleeve 10 is fixedly connected with three sets of evenly distributed draw rings 11 near the front end. The end of the draw rope 9 away from the rope sleeve 8 is fixedly connected to the draw ring 11. First, the head end of the cable body 15 is installed into the cable sleeve net 1 and pressed into the conical protective sleeve 10 to prevent the cutting corners of the cable body 15 from cutting the cable sleeve net 1 or affecting its expansion and contraction during the traction process. The elastic steel cable 4 can be pulled by squeezing the compression grip cable lock 5, so that the elastic steel cable 4 can be retracted. After retracting, the guide wheel 2 can be made to be tightly attached to the cable body 15 and the cable net 1. Furthermore, after moving the three groups of guide wheels 2 to make them evenly distributed on the outside of the cable body 15, the positioning kit 6 is moved to the metal hollow tubes 3 at both ends of the guide wheel 2 and tightened, and then the lower end of the guide wheel 2 can be tightened on the elastic steel cable 4 by screwing the fastener 7, thereby completing the fixation of the positioning kit 6. After repeating this operation, the guide wheel 2 can be positioned so that the three groups of evenly distributed guide wheels 2 will not shift during the dragging process, thereby maintaining uniform force and protecting the cable body 15. Compared with the traditional cable traction sleeve, the technical solution can support the cable net 1 and the cable body 15 through the design of the guide wheel 2 to play a protective role, avoiding damage caused by friction and collision with objects such as stones on the ground during traction. At the same time, the guide wheel 2 is provided with a bearing inside which can rotate when subjected to tension. Compared with the cable net 1 and the cable body 15 directly dragged on the ground, it can effectively reduce friction, reduce the load of the traction equipment, and improve traction efficiency.
[0020] See also Figure 1-Figure 2The three sets of guide wheels 2 are connected in series through elastic steel cables 4. Grip-type cable locks 5 are arranged at the head and tail of the elastic steel cables 4. The cable body 15 is arranged inside the cable net 1. The three sets of guide wheels 2 are evenly distributed on the outside of the cable body 15 through the positioning kit 6. The tail of the cable net 1 extends between the guide wheel 2 and the cable body 15. The guide wheel 2 will be more and more tightly attached to the cable net 1 when being pulled, thereby improving the fitting effect between the rear end of the cable net 1 and the cable body 15, ensuring the traction effect of the cable net 1, and effectively avoiding the falling off.
[0021] See also Figure 3 A restraining piece 12 is provided at the head of the cable sheath 1, and a connecting steel cable 13 is fixedly connected to the middle of the front end of the conical protective sheath 10. The connecting steel cable 13 is fixedly connected to the restraining piece 12, and the guide wheel 2 and other components are connected to the pull rope 9 and the pull ring 11 through the rope sheath 8, so that the guide wheel 2 will not fall off during the traction process. At the same time, the guide wheel 2 will also provide a backward pulling force to the conical protective sheath 10 through the pull rope 9, thereby effectively avoiding the separation of the conical protective sheath 10 and the head end of the cable body 15, thereby ensuring the protective effect of the conical protective sheath 10.
[0022] See also Figure 1-Figure 2 The front end of the restraining member 12 is fixedly connected with a rope buckle 14, that is, the conical protective sleeve 10 and the restraining member 12 are connected by a connecting steel cable 13 to prevent them from falling off. The rope buckle 14 can be connected to the traction equipment, ensuring the rationality of the design.
[0023] Working principle: first, the head end of the cable body 15 is installed into the interior of the cable net 1, and pressed into the interior of the conical protective sleeve 10, so as to prevent the cutting sharp corners of the cable body 15 from cutting the cable net 1 or affecting its expansion and contraction during the traction process. By squeezing the pressure-grip cable lock 5, the elastic steel cable 4 can be pulled, so that the elastic steel cable 4 can make the guide wheel 2 close to the cable body 15 and the cable net 1 after contraction. Furthermore, after moving the three groups of guide wheels 2 to make them evenly distributed on the outside of the cable body 15, the positioning kit 6 is moved to the metal hollow tubes 3 at both ends of the guide wheel 2 and tightened, and then the lower end of the guide wheel 2 can be tightened against the elastic steel cable 4 by screwing the fastener 7, thereby completing the fixation of the positioning kit 6. After repeating this operation, the guide wheel 2 can be positioned so that the three groups of evenly distributed guide wheels 2 will not shift during the dragging process, thereby maintaining uniform force and protecting the cable body 15. Compared with the traditional cable traction sleeve, the technical solution can be used for the cable net through the design of the guide wheel 2. 1 and the cable body 15 are supported to play a protective role, thereby avoiding damage caused by friction and collision with objects such as stones on the ground during traction. At the same time, a bearing is arranged inside the guide wheel 2, which can rotate when subjected to tension. Compared with the cable net 1 and the cable body 15 directly dragging on the ground, it can effectively reduce friction, reduce the load of the traction equipment, and improve traction efficiency. In addition, the guide wheel 2 and other components are connected between the pull rope 9 and the pull ring 11 through the rope loop 8, so that the guide wheel 2 will not fall off during traction. At the same time, the guide wheel 2 will also provide a backward pulling force to the conical protective sleeve 10 through the pull rope 9, thereby effectively avoiding the separation of the conical protective sleeve 10 from the head end of the cable body 15, ensuring the protective effect of the conical protective sleeve 10, and at the same time, the guide wheel 2 will become more and more tightly attached to the cable net 1 when being pulled, thereby improving the fitting effect between the rear end of the cable net 1 and the cable body 15, ensuring the traction effect of the cable net 1, and effectively avoiding the occurrence of falling off.
