[0001] The invention relates to the technical field of wire rope joints, in particular to a wire rope joint and a wire rope scraper with the joint. Background Art

[0002] Steel wire rope is a spiral steel wire bundle twisted together according to certain rules with steel wires that meet the requirements of mechanical properties and geometric dimensions. Steel wire rope is composed of steel wire, rope core and grease. Steel wire rope is first twisted into strands by multiple layers of steel wires, and then a certain number of strands are twisted into a spiral rope with the rope core as the center. In material handling machinery, it is used for lifting, traction, tensioning and carrying.

[0003] In the industrial field, wire rope joint connection technology is the most commonly encountered and used technology in wire rope related technologies. Commonly used wire rope connection methods include wire rope clip connection, extrusion head connection, braided connection and other methods. However, in terms of joint connection under non-high-load-bearing conditions, when there is a problem with the wire rope, it is often difficult to separate it from the connecting mechanism and replace the wire rope. The difficulty in disassembly and assembly greatly affects work efficiency and increases the cost of use. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a wire rope joint and a wire rope scraper with the joint.

[0005] The present invention solves the technical problem by adopting the following technical solutions:

[0006] A wire rope joint comprises a rotatably connected male head and a female head. The conveying wire rope joint is fixed in the male head and the female head respectively by a top screw, and a transport component is fixedly connected to the outer sides of the male head and the female head.

[0007] Preferably, the male connector and the female connector are both provided with fixing holes for the wire rope to pass through, and one side of the outer wall of the male connector and the female connector is provided with a plurality of connecting holes that penetrate to the fixing holes, and the top screw is screwed into the threaded hole so that the wire rope is fixed in the male connector or the female connector.

[0008] Preferably, the fixing holes of the male connector and the female connector are coaxially arranged.

[0009] Preferably, an I-shaped structure is provided on the connecting female head.

[0010] Preferably, an end cap is fixed at the top of the female connector, and a fixing groove is provided at the bottom. The outer diameter of the end cap and the outer diameter of the bottom of the female connector are both larger than the outer diameter of the top of the female connector.

[0011] Preferably, one end of the male connector is sleeved in the fixing groove and is detachably rotatably connected to the female connector via a retaining spring.

[0012] Preferably, the connecting male head comprises a fixed end and a connecting end, the fixed end is sleeved in the fixing groove, and the connecting end is provided with a connecting hole.

[0013] Preferably, the fixing end is columnar and the outer diameter of the fixing end matches the inner diameter of the fixing groove, and the outer diameter of the connecting end is smaller than the outer diameter of the fixing end.

[0014] Preferably, the side wall of the fixing groove is provided with an annular groove, and when the fixing end is inserted into the fixing groove, the top surface of the annular groove and the bottom surface of the fixing end are in the same plane, and the retaining spring is clamped in the annular groove.

[0015] A wire rope scraper with a wire rope joint comprises the wire rope joint and a scraper group sleeved on the outer side of the wire rope joint.

[0016] The advantages and positive effects of the present invention are:

[0017] 1. The wire rope is detachably connected to the male or female connector through a top wire, so that when a problem occurs, the wire rope can be quickly separated from the male or female connector and replaced, thereby effectively improving work efficiency.

[0018] 2.

[0027] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings:

[0028] like Figure 1 As shown, the present invention provides a wire rope joint, which is suitable for non-high-load application scenarios. Specifically, in this embodiment, the wire rope joint is used in the field of powder conveying. The pipeline structure in the commonly used powder conveying device includes a hollow pipeline, a steel wire rope for conveying is arranged in the tube shell, and a plurality of scrapers are arranged on the steel wire rope for conveying powder, granules or other small-particle food materials. Since the powder conveying device relies on the steel wire rope scraper to transport the material, in order to meet the distance length of the transportation route, the steel wire ropes inevitably need to be docked to extend the length. In the prior art, manufacturers often stipulate that the strength of the docking point between the steel wire ropes is as large as possible to achieve the stability of the steel wire rope scraper during transportation. However, once the powder conveying device has material accumulation and blockage that makes the scraper unable to move, the steel wire rope scraper that meets the high-load use will generate a large resistance between the mechanical parts in the powder conveying device, thereby causing damage to the steel wire rope scraper and the powder conveying device. Therefore, the present invention provides a wire rope joint, wherein the wire rope joint and the wire rope are connected to each other in a non-high-load-bearing manner through a top wire, which can ensure that the wire rope connection has sufficient strength to transport materials when the powder conveying device and the wire rope scraper are working normally, and can also ensure that when material accumulation and blockage occur between the powder conveying device and the wire rope scraper, the wire rope and the wire rope joint will be separated from the top wire due to excessive tension, thereby effectively protecting the wire rope scraper and the powder conveying device. Specifically, the wire rope joint includes a rotatably connected male connector 1 and a female connector 2, and the conveying wire rope joint is fixed in the male connector 1 and the female connector 2 respectively through the top wire, and a transport component is fixedly connected to the outer side of the male connector 1 and the female connector 2. Specifically, in this embodiment, the transport component is a scraper group 7.

[0029] Furthermore, if Figure 1As shown, the male connector 1 and the female connector 2 are both provided with fixing holes for the steel wire rope to pass through, and the outer wall of the male connector 1 and the female connector 2 are both provided with a plurality of connecting holes 3 that penetrate the fixing holes, and the top screw 4 is screwed into the threaded hole so that the steel wire rope is fixed in the male connector 1 or the female connector 2. During use, the first steel wire rope 9 joint is fixed in the fixing hole of the female connector 2 through the top screw 4, and the second steel wire rope 10 joint is fixed in the fixing hole of the male connector 1 through the top screw 4, and then the female connector 2 is connected to the male connector 1, so that the fixed connection between the first steel wire rope 9 and the second steel wire rope 10 can be achieved. In this embodiment, the male connector 1 and the female connector 2 are each provided with two connecting holes 3, and the axes of the two connecting holes 3 are parallel to each other, which is convenient for the staff to install and disassemble. In another embodiment of the present invention, the number of connecting holes 3 on the connecting male head 1 and the connecting female head 2 can be selected according to actual conditions, and the axes of each connecting hole 3 can also be selected to be parallel or non-parallel according to actual conditions. When the steel wire rope needs to withstand a greater tension than that in the first embodiment, the number of connecting holes 3 should be increased, and the positional relationship between the axes of each connecting hole 3 should be non-parallel, thereby achieving the effect of enhancing the connection stability between the steel wire rope and the connecting male head 1 or the connecting female head 2.

[0030] In actual use, the staff regulates the torsion between the top wire 4 and the connection hole 3 or the top wire 4 and the wire rope to ensure that the wire rope scraper can be separated from the top wire 4 when material accumulation or blockage occurs. At the same time, it should also be ensured that the torsion between the top wire 4 and the connection hole 3 or the top wire 4 and the wire rope supports the wire rope scraper to work normally during the normal operation of the powder transportation device. In this way, the protection effect of the wire rope scraper and the powder transportation device can be achieved. At the same time, the scraper group 7 is arranged outside the wire rope joint, which can effectively reduce the contact area between the wire rope joint and the material, thereby increasing the service life of the wire rope joint.

[0031] Furthermore, if Figure 1 , Figure 2 , Figure 3 As shown, the fixing holes of the male connector 1 and the female connector 2 are coaxially arranged, thereby ensuring that the force between the male connector 1 and the female connector 2 is more uniform when there is a tensile force, that is, the connection is more stable.

[0032] Furthermore, if Figure 1 , Figure 2 As shown, an I-shaped structure is provided on the female connector 2. The I-shaped structure enables the female connector 2 and the male connector 1 fixedly connected thereto to be fixed in the scraper assembly 7, thereby effectively preventing relative displacement between the wire rope joint and the scraper assembly 7.

[0033] Furthermore, if Figure 1 , Figure 2 As shown, the top of the female connector 2 is fixed with an end cap, and the bottom is provided with a fixing groove 5, and the outer diameter of the end cap and the bottom of the female connector 2 are both larger than the outer diameter of the top of the female connector 2. Specifically, the top of the female connector 2 is the belly column part of the I-shaped structure, and the scraper group 7 can be mounted on the top of the female connector 2, and fixed on the top of the female connector 2 based on the restrictions of the end cap and the bottom of the female connector 2.

[0034] Furthermore, if Figure 1 , Figure 2 , Figure 3 As shown, one end of the male connector 1 is sleeved in the fixing groove 5 and is detachably connected to the female connector 2 through the retaining spring 6. Specifically, in this embodiment, the fixing groove 5 is provided at the bottom end of the female connector 2, and the top end of the female connector 2 is provided with a connecting hole 3. The design of the rotating connection between the male connector 1 and the female connector 2 enables the first steel wire rope 9 joint and the second steel wire rope 10 joint to rotate 360 ​​degrees relative to each other, thereby effectively avoiding the twisting and winding of the steel wire rope during use and affecting the strength of the steel wire rope.

[0035] Furthermore, if Figure 2 As shown, the male connector 1 includes a fixed end 11 and a connecting end 12 . The fixed end 11 is inserted into the fixing groove 5 , and the connecting end 12 is provided with a connecting hole 3 .

[0036] Furthermore, if Figure 2 , Figure 3 As shown, the fixed end 11 is columnar and the outer diameter of the fixed end 11 matches the inner diameter of the fixed groove 5. The columnar design of the fixed end 11 allows the connecting male head 1 and the connecting female head 2 to rotate freely in the horizontal direction. It should be added that the depth of the fixing groove 5 is greater than the thickness of the fixed end 11, and the outer diameter of the connecting end 12 is smaller than the outer diameter of the fixed end 11, so that there is a free space between the connecting end 12 and the side wall of the fixing groove 5 for the retaining ring 6 to be installed or removed.

[0037] Furthermore, if Figure 2 , Figure 3 As shown, the side wall of the fixing groove 5 is provided with an annular groove 51. When the fixing end 11 is inserted into the fixing groove 5, the top surface of the annular groove 51 and the bottom surface of the fixing end 11 are in the same plane. Specifically, during use, the retaining spring 6 is fixed in the fixing groove 5 and at the same time presses against the bottom surface of the fixing end 11, so that the fixing end 11 can be fixed in the fixing groove 5, that is, the connecting male head 1 is fixedly connected to the connecting female head 2.

[0038] like Figure 4 , Figure 5As shown, the present invention also provides a wire rope scraper set 7 with a wire rope joint. Specifically, the wire rope scraper with a wire rope joint includes a wire rope joint and a scraper set 7 sleeved on the outside of the wire rope joint. In this embodiment, the scraper set 7 is composed of two semicircular scrapers with the same structure, the wire rope joint is sleeved between the two semicircular scrapers, the two semicircular scrapers are combined and connected by bolts, so that the wire rope joint can be fixed in the semicircular scraper. It should be supplemented that the scraper set 7 is provided with a groove 8 that matches the wire rope joint.

[0039] The working process of the present invention is as follows:

[0040] A wire rope joint: first, insert the first wire rope 9 joint into the fixing hole of the connecting female head 2 and fix it through the top screw 4, then insert the second wire rope 10 joint into the fixing hole of the connecting male head 1 and fix it through the top screw 4, and finally insert the fixed end 11 of the connecting male head 1 into the fixing groove 5 of the connecting female head 2 until the top surface of the fixed end 11 contacts the bottom surface of the fixing groove 5. At this time, install the retaining spring 6 into the annular retaining groove 51 of the connecting female head 2 to achieve a fixed connection between the first wire rope 9 and the second wire rope 10.

[0041] A wire rope scraper with a wire rope joint: two semicircular scrapers are placed on both sides of an installed wire rope joint, the two semicircular scrapers are combined and fixedly connected by bolts, thereby realizing the assembly of the wire rope scraper with the wire rope joint.

[0042] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive, and therefore the present invention is not limited to the embodiments described in the specific implementation manners. Any other implementation manners derived by those skilled in the art based on the technical solutions of the present invention also fall within the scope of protection of the present invention.
