Description

Technical Field

[0001] This application relates to the field of hydraulic technology, and more specifically to a handrail cable wire rope joint clamping device. Background Technology

[0002] In the manufacturing process of handrail cables, the connection between the wire rope and the splice is a crucial step, as its quality directly affects the safety and lifespan of the handrail cable. Achieving this connection typically requires pressing the wire rope and splice together to form a stable joint.

[0003] Currently, the pressing equipment used in the traditional manufacturing process of wire rope joints is mostly large hydraulic equipment. These machines are often bulky and complex in structure, and need to be fixedly installed in the production workshop, making them difficult to move. This limits the processing of wire rope joints to the workshop environment. When it is necessary to process wire rope joints for handrail cables on ships or in field operations, traditional equipment simply cannot meet the requirements.

[0004] Therefore, traditional wire rope splice pressing equipment has significant shortcomings in terms of size, cost, operation, and environmental adaptability, and cannot meet the on-site processing needs of handrail cable wire rope splices in shipbuilding and field operations. Utility Model Content

[0005] The purpose of this application is to provide a handrail cable wire rope joint crimping device to meet the needs of on-site processing of handrail cable wire rope joints in shipbuilding and field operations.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: a handrail cable wire rope joint crimping device is provided, comprising: a crimping mechanism, which is used to crimp the wire rope and the joint sleeve together, the crimping mechanism being provided with an oil inlet; and an ultra-high pressure oil pump, which is provided with an oil outlet. The crimping mechanism and the ultra-high pressure oil pump are connected through the oil inlet and the oil outlet, thereby the ultra-high pressure oil pump outputs hydraulic oil to the crimping mechanism to crimp the wire rope and the joint sleeve together.

[0007] Meanwhile, the clamping mechanism includes a support body, a hydraulic cylinder assembly, an upper clamping die, and a lower clamping die. One end of the hydraulic cylinder assembly is connected to the support body, and the other end is connected to the lower clamping die. The upper clamping die is connected to the support body, and the oil inlet is located in the hydraulic cylinder assembly. The wire rope and the connector sleeve are placed in the lower clamping die. The ultra-high pressure oil pump outputs hydraulic oil to the hydraulic cylinder assembly, so that the hydraulic cylinder assembly drives the lower clamping die to approach the upper clamping die to close the die and complete the clamping of the wire rope and the connector sleeve.

[0008] As another preferred embodiment, the cylinder assembly, the upper die, and the lower die are arranged along the vertical direction of gravity; wherein, the cylinder assembly drives the lower die to move vertically from bottom to top, so that the lower die overcomes the effect of gravity and moves closer to the fixed upper die to complete the mold closing.

[0009] In a further preferred embodiment, the cylinder assembly includes a hydraulic cylinder, a piston, and a piston connecting plate. The hydraulic cylinder is connected to the bracket body, and the piston connecting plate is connected to the hydraulic cylinder through the piston. A lower pressing mold is connected to the piston connecting plate.

[0010] In a further preferred embodiment, the bracket body includes a base, a support rod, and a top plate. The hydraulic cylinder assembly is fixedly connected to the base, the upper pressure mold is connected to the top plate, and the relative position between the top plate and the base is fixed and connected by the support rod.

[0011] Preferably, the oil inlet is located on the side of the cylinder assembly near the base.

[0012] Preferably, the upper die is detachably connected to the top plate; and or, the lower die is detachably connected to the piston connecting plate.

[0013] Preferably, the support rod includes a first support rod and a second support rod. One end of the first support rod is connected to the top plate and the other end is connected to the base. One end of the second support rod is connected to the top plate and the other end is connected to the base. The first support rod and the second support rod are respectively located on opposite sides of the hydraulic cylinder assembly. The first support rod cooperates with the second support rod to achieve fixed support for the top plate.

[0014] Preferably, the first support rod, the second support rod, and the top plate are detachably connected.

[0015] Preferably, the ultra-high pressure oil pump includes an oil cylinder, a pump body, a pressure gauge, and a drive arm. The oil outlet is located on the oil cylinder, the pressure gauge is connected to the oil outlet, the pump body is connected to the oil cylinder, and the drive arm abuts against the pump body. The drive arm then squeezes the pump body to drive the oil cylinder to output hydraulic oil from the oil outlet.

[0016] Preferably, the drive arm is a hand crank structure, with one end of the drive arm rotatably connected to the oil cylinder via the pump body, and the other end extending outward away from the oil cylinder as the operating end; wherein, the drive arm forms a cantilever structure with the end near the pump body as the fulcrum, and the pump body is driven to perform an oil injection action on the oil cylinder by pressing down the operating end.

[0017] Compared with the prior art, the beneficial effects of this application are as follows:

[0018] The handrail cable wire rope joint crimping device provided in this application does not rely on fixed workshops or large equipment. Through the combination of various parts of the integrated crimping mechanism, such as the support body and the hydraulic cylinder assembly, with the ultra-high pressure oil pump, the joint processing can be completed directly on the ship deck or in the field. This solves the problem that traditional fixed workshop processing cannot meet the needs of field and ship mobile operations, thereby realizing on-site processing and greatly improving operational flexibility.

[0027] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0030] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0031] In a preferred embodiment, see Figures 1 to 7 This application provides a handrail cable wire rope joint crimping device 1, which includes: a crimping mechanism 10, which is used to crimp the wire rope 2 and the joint sleeve 3 to form a joint, and the finished handrail cable is obtained after the joint is crimped. The crimping mechanism 10 is provided with an oil inlet port 11; an ultra-high pressure oil pump 20, which is provided with an oil outlet port 21. The crimping mechanism 10 and the ultra-high pressure oil pump 20 are connected through the oil inlet port 11 and the oil outlet port 21. Specifically, the oil inlet port 11 and the oil outlet port 21 are connected through a high pressure oil pipe 4, so that the ultra-high pressure oil pump 20 outputs hydraulic oil to the crimping mechanism 10 to crimp the wire rope 2 and the joint sleeve 3.

[0032] Also see Figure 2 and Figure 3The crimping mechanism 10 includes a support body 12, a cylinder assembly 13, an upper die 14, and a lower die 15. The support body 12 supports the cylinder assembly 13, the upper die 14, and the lower die 15. One end of the cylinder assembly 13 is connected to the support body 12, and the other end is connected to the lower die 15. The upper die 14 is connected to the support body 12. An oil inlet 11 is located on the cylinder assembly 13. The lower die 15 and the upper die 14 have various sizes and models to meet the pressing and forming requirements of different joints. The wire rope 2 and the joint sleeve 3 are placed in the lower die 15. The ultra-high pressure oil pump 20 outputs hydraulic oil to the cylinder assembly 13, so that the cylinder assembly 13 drives the lower die 15 to approach the upper die 14 to close the mold and complete the pressing of the wire rope 2 and the joint sleeve 3.

[0033] The handrail cable wire rope joint crimping device 1 provided in this application does not rely on a fixed workshop or large equipment. Through the combination of various parts in the integrated crimping mechanism 10, such as the bracket body 12 and the hydraulic cylinder assembly 13, with the ultra-high pressure oil pump 20, the joint processing can be completed directly on the ship deck or in the field. This solves the problem that traditional fixed workshop processing cannot meet the needs of field and ship mobile operations, thereby realizing on-site processing and greatly improving operational flexibility.

[0034] Meanwhile, the crimping mechanism 10 and the ultra-high pressure oil pump 20 are quickly connected through an interface, and the power supply relies solely on the ultra-high pressure oil pump 20, without the need for additional electrical equipment. The handrail cable wire rope joint crimping device 1 has a compact overall structure, making it easy to transport and set up in narrow spaces on ships or rugged outdoor sites. It solves the problem that traditional large crimping equipment is difficult to enter the site and improves adaptability to the working environment.

[0035] The bracket body 12, together with the cylinder assembly 13, upper mold 14, and lower mold 15, forms a small-volume clamping mechanism 10, which is easy to store and arrange in the confined space of a ship's cabin without taking up too much valuable space. When working in the field, the small-volume clamping mechanism 10 is easier to carry and transport, and can adapt to the handling needs of rugged terrain and changing environments.

[0036] Specifically, the hydraulic cylinder assembly 13, the upper pressure mold 14, and the lower pressure mold 15 are arranged in the vertical direction of gravity; the hydraulic cylinder assembly 13 drives the lower pressure mold 15 to move vertically from bottom to top, so that the lower pressure mold 15 overcomes the effect of gravity and moves closer to the fixed upper pressure mold 14 to complete the mold closing operation.

[0037] The hydraulic cylinder assembly 13 drives the lower pressing mold 15 to move, cooperating with the fixed upper pressing mold 14 to achieve bottom-up mold closing. This is applicable to the clamping mechanism 10 in this application. Since the clamping mechanism 10 is a portable, small-volume outdoor hydraulic tool, this mold closing setup does not require additional lifting drive devices, such as cylinders, for the upper pressing mold 14, as is the case with large hydraulic equipment in factories. Instead, during the joint pressing operation, the ultra-high pressure oil pump 20 directly provides hydraulic driving force to the hydraulic cylinder assembly 13 to achieve mold closing. After mold closing, the lower pressing mold 15 can fall back solely by its own weight. This not only reduces auxiliary components such as cylinders and control valves, simplifying the overall structure and reducing the complexity and manufacturing cost of the equipment, but also improves the operational reliability and portability of the mechanism by reducing mechanical connection points, making it particularly suitable for environments with limited maintenance conditions, such as ships or in the field.

[0038] Further preferably, the cylinder assembly 13 includes a hydraulic cylinder 131, a piston 132, and a piston connecting plate 133. The hydraulic cylinder 131 is connected to the bracket body 12, and the piston connecting plate 133 is connected to the hydraulic cylinder 131 via the piston 132. A lower pressing mold 15 is connected to the piston connecting plate 133. Preferably, the piston connecting plate 133 and the lower pressing mold 15 are detachably connected. Specifically, the piston connecting plate 133 and the lower pressing mold 15 are detachably connected by nuts, studs, bolts, etc. (See [reference]). Figure 2 Bolts are inserted into both sides of the lower die 15 to mate with the piston connecting plate 133.

[0039] In a further preferred embodiment, the bracket body 12 includes a base 121, a support rod 122 and a top plate 123. The hydraulic cylinder assembly 13 is fixedly connected to the base 121, the upper pressure mold 14 is connected to the top plate 123, and the relative position between the top plate 123 and the base 121 is fixed and connected by the support rod 122.

[0040] For further optimization, see [link to relevant documentation]. Figure 1 and Figure 3 The oil inlet 11 is located on the side of the cylinder assembly 13 near the base 121. Since the driving mold closing path of the hydraulic cylinder 131 in the cylinder assembly 13 is from bottom to top, the oil inlet 11 located near the base 121 can facilitate the transmission of hydraulic oil input from the ultra-high pressure oil pump 20.

[0041] Preferred, see Figure 3The support rod 122 includes a first support rod 1221 and a second support rod 1222. The first support rod 1221 and the second support rod 1222 have the same structure, and both the first support rod 1221 and the second support rod 1222 are preferably made of metal rods to provide higher support strength. One end of the first support rod 1221 is connected to the top plate 123 and the other end is connected to the base 121. One end of the second support rod 1222 is connected to the top plate 123 and the other end is connected to the base 121. The first support rod 1221 and the second support rod 1222 are respectively located on opposite sides of the cylinder assembly 13. The first support rod 1221 cooperates with the second support rod 1222 to achieve fixed support for the top plate 123.

[0042] The first support rod 1221 and the second support rod 1222 are respectively located on opposite sides of the cylinder assembly 13, forming a symmetrical support structure. This symmetrical layout allows the force on the top plate 123 to be evenly transmitted to the base 121, avoiding swaying or tilting of the mechanism due to uneven force distribution. This stable support effect is particularly important in environments with rough seas or uneven ground during field operations, ensuring that the clamping mechanism 10 remains stable during operation, thereby guaranteeing the clamping accuracy of the wire rope 2 joint.

[0043] Preferably, the first support rod 1221, the second support rod 1222, and the top plate 123 are detachably connected. Specifically, the tops of the first support rod 1221 and the second support rod 1222 are assembled using stud and nut assemblies. Since the top plate 123 is detachable from the first support rod 1221 and the second support rod 1222, the clamping mechanism 10 only needs to remove the nut on the top of the top plate 123 during storage to detach the top plate 123 from the first support rod 1221 and the second support rod 1222, thus facilitating storage and carrying, and simplifying assembly. Meanwhile, the connection between the upper mold 14 and the top plate 123 is the same as that between the lower mold 15. Therefore, in the clamping mechanism 10 of this application, preferably, both the lower mold 15 and the upper mold 14 can be replaced as needed and under different working conditions, and the replacement process is relatively convenient.

[0044] Preferably, the ultra-high pressure oil pump 20 includes an oil cylinder 22, a pump body 23, a pressure gauge 24, and a drive arm 25. The oil outlet 21 is located on the oil cylinder 22, the pressure gauge 24 is connected to the oil outlet 21, the pump body 23 is connected to the oil cylinder 22, and the drive arm 25 abuts against the pump body 23. The drive arm 25 then squeezes the pump body 23 to drive the oil cylinder 22 to output hydraulic oil from the oil outlet 21.

[0045] Preferably, the drive arm 25 is a hand crank arm structure. One end of the drive arm 25 is rotatably connected to the oil cylinder 22 via the pump body 23, and the other end extends outward away from the oil cylinder 22 as the operating end 26. The drive arm 25 forms a cantilever structure with the end near the pump body 23 as the fulcrum. By pressing down the operating end 26, the pump body 23 is driven to perform an oil injection action on the oil cylinder 22.

[0046] Therefore, see Figure 6 The specific process of using the handrail cable wire rope joint crimping device 1 described in this application to crimp the wire rope 2 and the joint sleeve 3 to obtain the finished handrail cable is as follows: When using the handrail cable wire rope joint crimping device 1 on a ship, the joint sleeve 3 to be crimped is placed in the lower pressing mold 15, and one end of the wire rope 2 is placed into the unfolded joint sleeve 3. The joint sleeve 3 can be made of materials such as aluminum alloy, stainless steel, or carbon steel as needed; the oil inlet 11 in the crimping mechanism 10 is connected to the oil outlet 21 of the ultra-high pressure oil pump 20. During the docking and pressing process, the operator holds the operating end 26 of the drive rod in the ultra-high pressure oil pump 20 and presses down the drive rod to allow the hydraulic oil from the ultra-high pressure oil pump 20 to enter the oil inlet from the oil outlet joint through the high pressure oil pipe 4. The oil pressure pushes the piston 132 of the hydraulic cylinder 131 upward, thereby driving the piston connecting plate 133 and the lower pressing die 15 upward, realizing the closing of the lower pressing die 15 and the upper pressing die 14, thus pressing the joint sleeve 3 between the upper pressing die 14 and the lower pressing die 15 tightly, so that the wire rope 2 is tightly pressed between the joint sleeve 3. After pressing is completed, the lower pressing die 15 moves down, and the finished handrail rope is taken out from between the upper pressing die 14 and the lower pressing die 15. Figure 7 As shown.

[0047] Preferably, the ultra-high pressure oil pump 20 can generate power oil with a maximum pressure of 80 MPa, while the hydraulic cylinder 131 of the clamping mechanism 10 in the handrail cable wire rope joint clamping device 1 can withstand a high pressure of 55 MPa. The effective area of ​​the piston 132 is 32 cm². 2 With a stroke of 60mm, it can generate a maximum pressure of 55×32×10×10=176000N (17.6 tons). Simultaneously, under the influence of strong friction, the wire rope joint becomes exceptionally robust. Furthermore, the hydraulic pressure can be adjusted within the range of 10-80MPa according to different working conditions, offering strong adaptability.

[0048] Furthermore, even in field operations, the appropriate lower pressure mold 15 and upper pressure mold 14 can be selected according to actual needs and installed onto the corresponding piston connecting plate 133 and top plate 123. By adjusting the pressure of the ultra-high pressure oil pump 20, it can meet different working requirements within the range of 10-80MPa. An aluminum alloy connector sleeve 3 can be used to complete the crimping of the wire rope 2 connector. The entire process is simple to operate, and the equipment is lightweight, easy to carry and operate.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
