Description

Technical Field

[0001] This application relates to the field of cable production, and in particular to a cable for mining equipment and its production process. Background Art

[0002] Cables are necessary basic products in the future electrified and information-based society. There are many cables in mining operation areas, and the operation of mining equipment cannot do without cables in many cases. Cables transmit electric energy and signals for mining equipment.

[0003] In related technologies, cables for mining equipment are mostly conventional rubber-sheathed cables.

[0004] However, the mining environment is complex and harsh. Especially the ground is uneven. When some mining equipment is operating or moving, it is inevitable to drag the cable, and the operating personnel will also drag some cables. The uneven and locally sharp road surface is extremely easy to wear the cable, resulting in the cable being affected in its overall use due to local damage. Summary of the Invention

[0005] In order to reduce the wear degree of the cable, this application provides a cable for mining equipment and its production process.

[0006] In a first aspect, this application provides a cable for mining equipment, adopting the following technical scheme:

[0007] A cable for mining equipment includes a supporting part, several of which are provided, and the supporting part is sleeved outside the cable part; chains, and multiple chains are provided between adjacent two supporting parts, and both ends of the chains are connected to the supporting part.

[0008] By adopting the above technical scheme, first, an explanation is made. This application does not provide anti-wear protection for the entire cable because the cable itself has a certain degree of anti-wear ability. This application mainly targets the cable placed on extremely harsh ground and provides protection for the local cable. Therefore, before installing the supporting part, it is necessary to determine the position of the cable part to be protected, and then install the supporting part and the chains. The supporting part raises the cable part, and the chains are adjusted below the cable part. At this time, when pulling the cable part, the cable part raised by the supporting part is not easy to contact the harsh ground, reducing the wear. Even if it contacts, there are chains to block, reducing the possibility of wear between the cable part and the uneven ground, and enhancing the anti-wear degree of the entire cable.

[0009] Optionally, in the length direction of the cable part, the supporting parts at both ends are oiling parts, and there is an oil-applying member with oil liquid between the oiling parts and the cable part.

[0010] By adopting the above technical solution, since sometimes the mine ground is too rough and the movement obstruction between the support part and the ground is too great, when the cable is pulled (sometimes the cable needs to be moved locally), relative slippage will occur between the cable part and the support part. However, this is actually one of the designs of the present application, because it can ensure that the support part remains on the roughest section of the mine ground, so that the support part is not affected by the pulling of the cable part. However, sometimes due to various factors, after the cable part is pulled, although displacement occurs between the cable part and the support part, the cable part is finally connected. It is placed on an uneven and harsh ground, and the smear piece smears oil on the outside of the cable part, which avoids the possibility of wear of the cable part that is pulled out to the entire protective section (composed of the support part and the chain), because at this time, there is oil outside the cable part and lubrication operation occurs, which causes sliding between the ground and the cable part, and the uneven ground will hardly leave marks on the cable part, which naturally solves the wear problem. Even if the oil becomes viscous after drying, it can form an oil layer outside the cable part, which can also play a role in protecting the rubber outside the cable part.

[0011] Optionally, the smear member is a cloth, a fabric or a sponge, and the smear member is provided between all the support parts and the cable parts.

[0012] By adopting the above technical solution, cloth, fabric and sponge are one of the materials for the smear that are easiest to apply oil, and are also relatively cheap. They are one of the preferred solutions for the smear of the present application. The smear on the inner side of the support part acts as a cushion block, making the connection between the support part and the cable part more secure. At the same time, by adopting the material of the smear of the present application, the friction between the coating part and the cable part will not be too large, and the support part and the cable part can be clamped, which is also convenient for the relative movement of the two.

[0013] Optionally, the support portion is detachably connected to the cable portion.

[0014] By adopting the above technical solution, the support part and the cable part can be detachably connected, which makes it easy to install the support part, and also easy to replace and disassemble the support part, thus providing convenience for the placement of the applicator.

[0015] Optionally, the supporting portion includes an inner ring and an outer ring, the inner ring is detachably connected to the cable portion, the inner ring is sleeved outside the cable portion, the smear member is arranged between the inner ring and the cable portion, the outer ring is detachably connected to the inner ring, the outer ring is sleeved outside the inner ring, an annular groove is formed on the inner wall of the outer ring along the circumference of the outer ring, a limiting member is provided on the outside of the inner ring, the limiting member extends into the annular groove, and the inner ring and the outer ring rotate relatively to each other.

[0016] By adopting the above technical solution, the inner ring is connected to the cable part, and the inner ring rotates relative to the outer ring, reducing the influence of the rotation of the cable part on the outer ring and avoiding the need for operators to frequently adjust the support part.

[0017] Optionally, a support rod for supporting the support part is provided on the outer ring.

[0018] By adopting the above technical solution, the support rod plays a role in supporting and stabilizing the support part, making the placement of the support part more stable. At the same time, the support rod is easy to insert into the concave position of the uneven ground, making the position of the support part more fixed and ensuring that the support part is located on the most rugged road surface.

[0019] Optionally, sliders are connected to both ends of the chain, and the sliders are slidably connected to the outer ring, and the sliders slide along the circumferential direction of the outer ring.

[0020] By adopting the above technical solution, when the support part accidentally overturns, since the chain can slide on the outer ring, according to the action of gravity, the chain will try to slide under the cable part as much as possible. Before the outer ring accidentally rotates and is not corrected in time, the sliding chain can protect the bottom of the cable part to the greatest extent.

[0021] Optionally, the outer ring includes two first half rings, one end of the two first half rings is hinged to each other, and the other end is detachably connected; the inner ring includes two second half rings, one end of the two second half rings is hinged, and the other end is detachably connected, and a limiting member is provided on each of the two second half rings.

[0022] By adopting the above technical solution, the present application provides a preferred structure for the outer ring and the inner ring, which is easy to install and disassemble the outer ring and the inner ring.

[0023] Optionally, a receiving groove is formed in the inner wall of the inner ring of the oiling part, and the smearing member is located in the receiving groove.

[0024] By adopting the above technical solution, the existence of the receiving groove enables a larger smearing member to be placed in the oiling part, which can also hold more oil, reducing the frequency of refueling.

[0025] In a second aspect, the present application provides a production process for a cable for mining equipment, adopting the following technical solution:

[0026] A production process for a cable for mining equipment, for producing a cable for mining equipment, the steps are as follows:

[0027] Place the smearing member in the support part;

[0028] Apply oil to the smearing member in the oiling part;

[0029] Connect several of the support parts together through the chain;

[0030] Clamp and fix the support part at the position where the cable part needs to be protected;

[0031] Gather the chains between adjacent support parts.

[0032] By adopting the above technical solution, it is convenient to process and produce the cable of the present application, and gathering the chains facilitates the later laying and protection.

[0033] In summary, the present application includes at least one of the following beneficial technical effects:

[0034] 1. The support part and the chain play a protective role for the cable part, reducing the wear degree of the cable;

[0035] 2. The coating member applies oil to the cable part, so that after relative movement occurs between the support part and the cable part, the wear degree of the cable part outside the protection section of the support part is reduced;

[0036] 3. The chain is slidably connected to the outer ring, and it is easy to adjust the position of the chain by itself. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0042] The following is a further detailed description of the present application in conjunction with the attached Figures 1-4 Make a further detailed description of the present application.

[0043] An embodiment of the present application discloses a cable for mining equipment.

[0044] Refer to Figure 1 , a cable for mining equipment includes a cable part 1, a support part 2 and a chain 3.

[0045] Referring to Figure 1 , the cable part 1 is a rubber cable, and there are several support parts 2. The support parts 2 are sleeved outside the cable part 1, and the support parts 2 are distributed at intervals on the cable part 1.

[0046] Referring to Figure 2 and Figure 3 , the support part 2 includes an inner ring 21 and an outer ring 22. The inner ring 21 is detachably connected to the cable part 1. The inner ring 21 is sleeved outside the cable part 1. The inner ring 21 includes two second half rings 211. One ends of the two second half rings 211 are hinged to each other in the arc direction at both ends, and the other ends are detachably connected by screws. The two second half rings 211 can form a complete ring. A fan-shaped plate-like limiting member 212 is welded on the outer wall of each of the two second half rings 211; the outer ring 22 is sleeved outside the inner ring 21. The outer ring 22 includes two first half rings 221. One ends of the two first half rings 221 are hinged to each other in the arc direction at both ends, and the other ends are detachably connected by screws. The two first half rings 221 form a complete ring. A ring groove 222 is formed along the circumferential direction of the inner wall of the outer ring 22. The limiting member 212 extends into the ring groove 222, and the limiting member 212 rotates in the ring groove 222 to realize the relative rotation between the inner ring 21 and the outer ring 22. A support rod 223 for supporting the support part 2 is welded on the outer ring 22. The support rods 223 are located on both sides of the cable axis. The support rods 223 extend in a direction away from the support part 2. One end of the support rod 223 is welded to the outer wall of the outer ring 22, and the other ends are arranged away from each other. The end of the support rod 223 away from the outer ring 22 is a tip.

[0047] Referring to Figure 1 , Figure 2 and Figure 3 , a receiving groove 213 is formed on the inner wall of the inner ring 21. A coating member 214 is placed in the receiving groove 213. The coating member 214 is cloth, fabric or sponge. When the support part 2 is installed outside the cable part 1, the coating member 214 contacts the cable part 1. When all the support parts 2 and the chain 3 are installed, in the length direction of the cable, the support parts 2 at both ends are oiling parts 20, and the coating member 214 between the oiling parts 20 and the cable part 1 is provided with oil.

[0048] Referring to Figure 4 , several chains 3 are provided between two adjacent support parts 2. Both ends of the chain 3 are slidably connected to the support part 2. Circular sheet-like sliders 31 are connected to both ends of the chain 3. Annular limiting grooves 224 are formed on both end walls distributed in the axial direction of the outer ring 22. The limiting grooves 224 open both ends of the first half ring 221 in the arc direction. The sliders 31 slide in the limiting grooves 224. The sliders 31 slide along the circumferential direction of the outer ring 22. After the outer ring 22 is opened, the sliders 31 can be taken out from the limiting grooves 224 of the first half ring 221.

[0049] The implementation principle of a cable for mining equipment in an embodiment of the present application is as follows: First, determine the rough and uneven positions in the mining environment. When the cable needs to pass through these positions, the support part 2 and the chain 3 are installed on the cable part 1 laid on this section of the ground. The chain 3 is arranged between two adjacent support parts 2, and the chain 3 is located below the cable part 1 when placed; Oil liquid is applied to the coating part 214 in the support part 2 at both ends. When relative displacement occurs between the cable part 1 and the support part 2, the oil liquid in the oil coating part 20 contaminates the cable part 1, forming an oil layer on the cable part 1, which can also play a role in anti-wear when there is no protection of the support part 2 and the chain 3. Using the cable of the present application can reduce the wear degree of the cable.

[0050] The embodiment of the present application also discloses a production process of a cable for mining equipment.

[0051] A production process of a cable for mining equipment is as follows:

[0052] Place the coating part 214 in the support part 2.

[0053] Apply oil liquid to the coating part 214 in the oil coating part 20.

[0054] Connect several support parts 2 together through the chain 3.

[0055] Clamp and fix the support part 2 at the position where the cable part 1 needs to be protected.

[0056] Gather the chain 3 between adjacent support parts 2.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
