Description

Technical Field

[0001] The utility model relates to the technical field of industrial cables, in particular to a highly wear-resistant and corrosion-resistant industrial installation cable. Background Art

[0002] In industrial environments, cables are key components for power transmission and signal transmission. Their performance and durability are crucial to the stable operation of the entire system. Especially in some harsh industrial environments, such as chemical plants, oil fields, mines, etc., cables need to withstand high temperature, high pressure, corrosion, wear and other factors. Therefore, it is particularly important to develop a highly wear-resistant and corrosion-resistant industrial installation cable.

[0003] In the existing cable technology, although some cable products have certain wear resistance and corrosion resistance, there are still some problems in actual use, especially in the docking of cables. Due to the complexity and diversity of docking conditions in industrial environments, traditional cable docking methods are often difficult to meet the requirements. Traditional cable docking methods usually adopt direct connection or use connectors for connection. However, in harsh industrial environments, these docking methods often have some problems. At the docking point, the outer sheath of the cable may be damaged or worn, causing moisture, chemicals, etc. to enter the cable, thereby affecting the performance and service life of the cable. Since the docking point is the weak link of the cable, it is easy to be physically damaged by the outside world, especially in a high-wear environment, the docking point is prone to damage or breakage.

[0004] Chinese patent document CN209674937U discloses a highly wear-resistant and corrosion-resistant industrial installation cable, including a reinforcing core, a reinforcing core protective sleeve, a cable core, an insulating protective sleeve, a first filling layer, a second filling layer and an outer protective sleeve, wherein the reinforcing core protective sleeve is sleeved on the outside of the reinforcing core, the insulating protective sleeve is sleeved on the outside of the cable core, the insulating protective sleeve and the cable core are evenly distributed on the outside of the reinforcing core protective sleeve, the first filling layer is arranged inside the insulating protective sleeve, and the second filling layer is arranged inside the outer protective sleeve; the outer surface of the outer protective sleeve is provided with a polyethylene low-temperature resistant layer, and the outer surface of the polyethylene low-temperature resistant layer is provided with a basalt fiber fireproof cloth layer; but there are still the following defects in the implementation process:

[0005] Although the device in the above document is corrosion-resistant, wear-resistant, low-temperature-resistant, fire-resistant, pressure-resistant, waterproof and moisture-proof, and can adapt to complex and changeable industrial environments, when two cables in the above document are connected, the outer sheath of the cable may be damaged or worn at the connection point, causing moisture, chemicals, etc. to enter the interior of the cable, thereby affecting the performance and service life of the cable. Utility Model Content

[0012] The above technical solution is adopted, in which a rubber layer is filled in the inner cavity of the connecting groove, so that the wear resistance and impact resistance of the cable can be increased by utilizing the rubber layer. Since the rubber layer has elasticity, it can provide additional protection when the cable is subjected to external friction or impact. The rubber layer has excellent chemical corrosion resistance and can resist corrosion by chemical substances such as acids, alkalis, and salts, thereby improving the overall wear resistance and corrosion resistance of the cable.

[0013] A further improvement of the technical solution of the utility model is that the limiting structure includes a clamp 1 and a clamp 2, the clamp 1 and the clamp 2 are squeezed together, the clamp 1 and the clamp 2 are slidably connected with a plurality of screws, and the outer surfaces of the plurality of screws are threadedly connected with nuts.

[0019] A further improvement of the technical solution of the utility model is that the first connector structure and the second connector structure are connected by threads.

[0020] By adopting the above technical solution, in this solution, the cooperation between the docking groove and the docking ring can be utilized to prevent external moisture, chemicals, etc. from entering the inner cavity of connecting ring one or the inner cavity of connecting ring two, and then entering the interior of the cable through the docking point of the two cables, thereby affecting the performance and service life of the cable.

Through the cooperation of the first connector structure and the second connector structure, the butt joint of the two sections of the cable can be prevented from being damaged or worn, thereby causing moisture, chemical substances, etc. to enter the interior of the cable, thereby affecting the performance and service life of the cable. The butt joint of the two sections of the cable can be protected to prevent it from being physically damaged by the outside, thereby causing damage or breakage.

After the docking of the two sections of cables is completed, the two limiting structures 5 are then slid on the outer surface of the sheath 4, thereby driving the first connector structure 6 and the second connector structure 7 to approach each other, and then the docking ring 62 is slid to the inner cavity of the docking groove 72, and then the first connector structure 6 is rotated, so that the cooperation between the thread 1 63 and the thread groove 73 drives the docking ring 62 to move in the inner cavity of the docking groove 72.

When the limiting structures 5 are sleeved, the first connector structure 6 and the second connector structure 7 are respectively driven to be sleeved on the outer surfaces of the two sections of cables, and then the two sections of cables are docked. After the docking of the two sections of cables is completed, the two limiting structures 5 are then slid on the outer surface of the sheath 4, thereby driving the first connector structure 6 and the second connector structure 7 to approach each other, and then the docking ring 62 is slid to the inner cavity of the docking groove 72, and then the first connector structure 6 is rotated, so that the cooperation between the thread 1 63 and the thread groove 73 drives the docking ring 62 to move in the inner cavity of the docking groove 72;

[0045] When the first connector structure 6 and the second connector structure 7 are connected together, a plurality of screws 53 are passed through the threaded holes of the clamp 1 51 and the clamp 2 52 in sequence, and then the clamp 1 51 and the clamp 2 52 are driven to be closed through the cooperation of the screws 53 and the nuts 54, so that the position of the limiting structure 5 on the surface of the sheath 4 can be limited to prevent the limiting structure 5 from sliding on the surface of the sheath 4, so that the position of the first connector structure 6 and the second connector structure 7 can be limited by the limiting structure 5, so that the cooperation of the first connector structure 6 and the second connector structure 7 can be used to protect the joint of the two sections of the cable, so as to prevent the joint of the cable from being damaged or worn during use, thereby causing moisture, chemicals, etc. to enter the inside of the cable, thereby affecting the performance and service life of the cable.
