Description

Technical Field

[0001] This utility model belongs to the field of wire rope maintenance equipment, specifically, it relates to an anti-twist wire rope maintenance machine that can quickly load and unload rope reels. Background Technology

[0002] Anti-twist steel wire ropes are widely used in power grid construction as essential tools in the process of cable tension erection. However, due to the relatively harsh working environment of traction steel wire ropes, they are prone to the adhesion of dirt such as mud and sand, forming grime on their surface. During operation, defects such as wear, fatigue, corrosion, and broken wires and kinks are easily generated, reducing the strength of the steel wire rope, shortening its lifespan, and seriously affecting construction efficiency and safety. Therefore, regular cleaning and maintenance of the steel wire ropes are necessary.

[0003] Chinese Patent CN117798103A discloses an environmentally friendly anti-torsion wire rope maintenance system, comprising: a wire rope, one end of which is coiled on a torque release device; the wire rope is also sequentially placed into an oil cleaning device, a high-pressure air cleaning device, and an oiling device; the other end of the wire rope is coiled on a rope winding device; the rope winding and unwinding mechanisms provide tension to the wire rope to be maintained; the rotation mechanism releases torque from the wire rope; and the rope winding mechanism ensures that the maintained wire rope is evenly wound on the winding reel. The oil cleaning device includes a set of static coarse brushes and a set of reciprocating powerful dynamic cleaning devices; the high-pressure air cleaning device is used to blow away small oil particles that were not dislodged by the reciprocating powerful dynamic cleaning devices; and the oiling device is used to apply grease to the surface of the wire rope by spraying.

[0004] The above technical solution has the following drawbacks:

[0005] The wire rope reel has a large, circular structure. To maximize space, it is often laid flat with a vertical shaft and stacked. The maintenance machine's end slots are horizontal shafts, requiring two lifting and reversing operations for loading and unloading the reel. Combined with the time spent loading and unloading the chuck shafts, this significantly impacts work efficiency and increases the workload for operators. Furthermore, while the above solution also includes cleaning and oiling functions, the oiling position and angle cannot be adjusted as needed. Utility Model Content

[0006] To address the above deficiencies, this utility model provides an anti-twist wire rope maintenance machine that allows for quick loading and unloading of rope reels, including a rope releasing device and a rope taking device located on the front and rear sides, and a maintenance mechanism located between the rope releasing device and the rope taking device.

[0007] The maintenance mechanism includes a cleaning mechanism, a hydraulic pump station, and an oil injection mechanism, which are distributed sequentially from the area closest to the rope release device to the area furthest away from the rope release device. The cleaning mechanism is used to clean the surface of the wire rope, and the hydraulic pump station is used to supply oil to the oil injection mechanism.

[0008] The oil injection mechanism includes a slide table, with a stepper motor and a bearing seat installed at the left and right ends of the slide table, respectively. The output end of the stepper motor is connected to a positive and negative lead screw via a coupling. Two sliders are threaded onto the positive and negative lead screws. The bottom ends of the two sliders are slidably mounted on a linear slide rail fixed on the upper surface of the slide table. The top of the two sliders is fixed with an oil injector adjustment bracket, and an oil injector is movably mounted on each oil injector adjustment bracket.

[0009] Both the rope-releasing device and the rope-retracting device are equipped with a rotatable mechanism.

[0010] Furthermore, each of the fuel injector adjustment brackets has two screw holes at different heights, and each screw hole is fitted with a hand screw. The fuel injector is installed on the fuel injector mounting base via inner and outer ribbon ear connectors, and the fuel injector mounting base is fixed to the fuel injector adjustment bracket by hand screws.

[0011] Furthermore, one of the two screw holes is a waist hole.

[0012] Furthermore, a limit switch mounting plate is installed on the slide, and a limit switch for controlling the stepper motor is installed on the limit switch mounting plate.

[0013] Furthermore, a motor guard is installed at the stepper motor, and an oil baffle is installed at the limit switch.

[0014] Furthermore, the slewing mechanism includes a rope release frame, the slewing frame is located inside the rope release frame, the rotating end of the slewing frame is rotatably connected to a large slewing bearing installed on the inner side wall of the rope release frame, the large slewing bearing is driven by a slewing frame pinion gear installed on the inner side wall of the rope release frame, and the slewing frame pinion gear is driven by a slewing frame motor installed on the outer side wall of the rope release frame.

[0015] The fixed end of the slewing frame is rotatably mounted with a chuck shaft via a small slewing bearing. The wire rope reel is sleeved on the outside of the chuck shaft and fixed to it by the pressure plate jaws. The end of the chuck shaft is also limited by a large locking nut. Similarly, the small slewing bearing is also synchronously driven by the chuck shaft motor and the chuck shaft pinion mounted on the fixed end of the slewing frame.

[0016] Furthermore, a hydraulic slip ring is installed at the rotating end of the slewing frame to supply hydraulic oil to the reverse slewing frame motor. A brake is also installed between the output end of the slewing frame motor and the pinion of the slewing frame to ensure reliable braking of the slewing frame. The side wall of the rope release frame is also equipped with a rope release and unloading valve and a torque release valve for oil return. At the same time, a protective cover for protecting the slewing frame motor is fixed on the side of the rope release frame.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] Both the rope winding and unwinding devices are rotatable, and the chuck shaft is integrated into the rotating frame, which facilitates quick loading and unloading of the rope reel, reduces the loading and unloading time of the rope reel, improves work efficiency, and reduces the labor intensity of the operators.

[0019] The method of installing fuel injectors in the existing technology has been changed, making it easier to adjust the angle of the fuel injectors, ensuring reliable sealing, and making the installation more secure. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example

[0029] like Figure 1 As shown, this embodiment provides an anti-twist wire rope maintenance machine that can quickly load and unload rope reels, including a rope releasing device 1 and a rope taking device 5 located on the front and rear sides, and a maintenance mechanism located between the rope releasing device 1 and the rope taking device 5.

[0030] The maintenance mechanism includes a cleaning mechanism 2, a hydraulic pump station 3, and an oil injection mechanism 4, which are distributed in sequence from the closest to the rope release device 1 to the furthest from the rope release device 1. The cleaning mechanism 2 is used to clean the surface of the wire rope, and the hydraulic pump station 3 is used to supply oil to the oil injection mechanism 4.

[0031] It should be noted that the specific structures of the cleaning mechanism 2 and the hydraulic pump station 3 mentioned above can be found in application number 202520755355.5, entitled "Structure in a Wire Rope Maintenance Equipment". For example, the cleaning mechanism 2 cleans the surface of the wire rope passing through it by means of a relatively rotating wire brush roller. Its function is the same, so it will not be described in detail here.

[0032] like Figures 3 to 4 As shown, the rope-releasing device 1 includes a rope-releasing frame 101 and a slewing frame 103 located inside the rope-releasing frame 101. The rotating end of the slewing frame 103 is rotatably connected to a large slewing support 110 installed on the inner side wall of the rope-releasing frame 101. The large slewing support 110 is driven by a slewing frame pinion 109 rotatably installed on the inner side wall of the rope-releasing frame 101. The slewing frame pinion 109 is driven by a slewing frame motor 107 installed on the outer side wall of the rope-releasing frame 101. Thus, the slewing frame motor 107 provides power to drive the slewing frame pinion 109 to rotate. Since the slewing frame pinion 109 meshes with the outer gear ring of the large slewing support 110, it can synchronously drive the slewing frame 103 and the wire rope reel 102 to rotate together, so that the wire rope torque is completely released. The orientation of the slewing frame can also be adjusted when loading and unloading the wire rope reel 102.

[0033] Additionally, a hydraulic slip ring 117 is installed at the rotating end of the slewing frame 103 to supply hydraulic oil to the reverse traction slewing frame motor 107. A brake 108 is also installed between the output end of the slewing frame motor 107 and the slewing frame pinion 109 to ensure reliable braking of the slewing frame 103. The side wall of the rope release frame 101 is also equipped with a rope release and take-up unloading valve 104 and a torque release unloading valve 105 for oil return. At the same time, a protective cover 106 for protecting the slewing frame motor 107 is fixed on the side of the rope release frame 101.

[0034] The fixed end of the slewing frame 103 is rotatably mounted with a chuck shaft 113 via a small slewing bearing 114. The wire rope reel 102 is sleeved on the outside of the chuck shaft 113 and fixed to it by the pressure plate jaws 111. At the same time, the end of the chuck shaft 11 is also limited by a large locking nut 112. Similarly, the small slewing bearing 114 is also synchronously driven by the chuck shaft motor 116 and the chuck shaft pinion 115 mounted on the fixed end of the slewing frame 103 to realize the reverse pulling operation.

[0035] like Figure 2 As shown, the oil injection mechanism 4 includes a slide table 41. A stepper motor 42 and a bearing seat 43 are respectively installed on the left and right ends of the slide table 41. The output end of the stepper motor 42 is connected to a positive and negative lead screw 44 through a coupling. Two sliders 45 are threadedly connected to the positive and negative lead screw 44 (the sliders 45 are threadedly connected to the positive and negative lead screw 44 through an internally embedded nut 416). The bottom ends of the two sliders 45 are slidably mounted on a linear slide rail 46 fixed on the upper surface of the slide table 41. An oil injector adjustment bracket 48 is fixed on the top of the two sliders 45. A limit switch mounting plate 412 is installed at the slide table 41. A limit switch 413 for controlling the stepper motor 42 is installed on the limit switch mounting plate 412. The stepper motor 42 is started by controlling the limit switch 413, and the stepper motor 42 drives the positive and negative lead screw 44 to rotate. The two sliders 45 located at opposite threads move closer or further apart from each other through the limit of the bottom linear slide rail 46, thereby adjusting the distance between the two oil injectors 47.

[0036] Each injector adjustment bracket 48 is movably mounted with an injector 47. Each injector adjustment bracket 48 has two screw holes at different heights, one of which is a waist hole, which can adjust the angle of the injector 47 so that the fan-shaped surface of the oil mist can better wrap the steel wire rope. Each screw hole is fitted with a hand-tightening screw 49. The injector 47 is mounted on the injector mounting base 411 through inner and outer ribbon ear connectors 410. The injector mounting base 411 is fixed to the injector adjustment bracket 48 by the hand-tightening screw 49.

[0037] Additionally, a motor guard 414 is installed at the stepper motor 42, and an oil baffle 415 is installed at the limit switch 413 to prevent the oil mist generated by the fuel injector 47 from damaging the stepper motor 42 and the limit switch 413 during operation.

[0038] like Figure 5 As shown, the rope winding device 5 has the same structure as the rope unwinding device 1. The difference is that the rotation of the rope winding device 5 is not used to release torque, but only to adjust the position of its chuck shaft when loading and unloading the wire rope reel 102. In addition, the rope winding device 5 is equipped with a rope laying device 51 and an oil collection tank 54. The rotating shaft 52 of the rope laying device 51 is rotatably mounted on the rope laying bracket 53 and is driven to rotate by a motor installed at the rope laying bracket 53. The oil collection tank 54 at the bottom is shaped with a higher front and a lower rear, so that the oil collects at the rear, which is convenient for regular cleaning.

[0039] like Figure 6 As shown, when installing the wire rope reel 102, rotate the slewing frame 103 so that the chuck shaft 113 is vertically upward, align the hoisted wire rope reel 102 with the chuck shaft 113, rotate the wire rope reel 102 during the descent so that the cross connector of the inner ring of the wire rope reel 102 falls into the four guide grooves of the chuck shaft 113, continue to fall and slightly shake so that the pin hole on the cross connector is aligned with the conical pin on the chuck shaft 113, continue to fall into place, and pass the pressure plate claw 111 through the chuck shaft 113 from the top. The four conical pins on the pressure plate claw 111 are embedded into the pin hole of the cross connector on the upper part of the rope reel. Finally, tighten with the large lock nut 112 to complete the installation. During forward pulling, the chuck shaft motor 116 does not start, and together with the rope winding device 5 arranged at the other end, it completes the tensioning of the wire rope and ensures that the wire rope passes through the oil injection mechanism 4 with constant tension and constant linear speed.

[0040] It should be noted that the structure described in this utility model can be implemented in many different forms and is not limited to the embodiments described. Any equivalent transformations made by those skilled in the art based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, such as the loading and unloading of other items, are included within the protection scope of this utility model.
