Description

Technical Field

[0001] This invention relates to the field of wire rope maintenance equipment, and in particular to an automatic maintenance and inspection trolley for hydraulic lifting wire ropes. Background Technology

[0002] The steel wire ropes used for lifting in water conservancy projects mainly refer to the steel wire ropes used at winches and gates in the water conservancy field or on gantry cranes. Because they are frequently in contact with water, they are more prone to corrosion and rust. In addition, a series of mechanical behaviors such as friction, wear, and breakage that occur inside the steel wire rope directly affect its load-bearing capacity and service life, thereby affecting the stability, reliability, and safety of water conservancy project operation. Therefore, compared with steel wire ropes in ordinary working environments, the steel wire ropes used for lifting in water conservancy projects have a higher maintenance level.

[0003] Currently, the maintenance of hoisting wire ropes in water conservancy projects mainly relies on manual labor. Various oiling tools are used to periodically maintain the wire ropes. This method is not only inefficient but also produces inconsistent maintenance results. Furthermore, manual maintenance is generally performed periodically, making real-time maintenance difficult. Additionally, when manually applying oil to the wire ropes, they are usually removed from the machine, as on-site manual maintenance is challenging in conditions such as at winches, gates, or gantry cranes in water conservancy projects. Summary of the Invention

[0004] Existing methods for maintaining wire ropes typically involve manual oiling using various tools. However, this approach is inefficient, lacks guaranteed maintenance effectiveness, and cannot provide real-time maintenance. Furthermore, manual maintenance is particularly challenging in hydraulic engineering projects involving wire ropes on winches, gates, and gantry cranes. This application presents an automatic maintenance and inspection trolley for hydraulic lifting wire ropes, with the following specific technical solution:

[0005] An automatic maintenance and inspection trolley for hydraulic lifting wire ropes includes a box body with a through hole for the wire rope to pass through. The box body is also equipped with a walking mechanism and an oiling assembly, which are spaced apart along the length of the through hole.

[0006] The traveling mechanism includes at least two clamping traveling components, which are evenly spaced along the circumference of the through hole inside the housing, and there is a clamping space between the two clamping traveling components, which coincides with the through hole;

[0007] Each clamping and traveling assembly includes a fixed rod and a traveling wheel. The fixed rod is installed in the housing along the length of the through hole, and the traveling wheel is installed on the fixed rod. The traveling wheels of the two clamping and traveling assemblies clamp the wire rope and travel on the wire rope.

[0008] Preferably, the traveling wheel is mounted on the fixed rod via the first wheel frame, and a torsion spring is provided between the first wheel frame and the fixed rod to keep the traveling wheel close to the wire rope.

[0009] Preferably, the clamping walking assembly further includes a first balance wheel and a second balance wheel, which are disposed on the fixed rod and located on both sides of the walking wheel.

[0010] Preferably, the first balance wheel is fixed to the fixed rod by the second wheel frame, the second balance wheel is set on the fixed rod by the third wheel frame, and torsion springs are respectively provided between the second wheel frame and the fixed rod and between the third wheel frame and the fixed rod. The third wheel frame is arranged crosswise with the first wheel frame and is detachably connected to the fixed rod. The first wheel frame, the third wheel frame and the second wheel frame are connected by a connecting rod.

[0011] Preferably, the oiling assembly includes an oil tank, an oil channel, and a flexible oiling component. The flexible oiling component is disposed inside the tank, and the oil tank is disposed inside the tank. The lubricating oil in the oil tank flows to the flexible oiling component through the oil channel.

[0012] Preferably, it also includes a head cleaning mechanism, including a cleaning wheel frame, balls and a cleaning wheel. The cleaning wheel has a through hole that coincides with a through hole. The inner wall of the cleaning wheel is a frosted surface, and the inner wall of the cleaning wheel is provided with raised patterns that are evenly spaced along its circumference and are adapted to the wire rope lay pitch. The cleaning wheel frame and the cleaning wheel are connected by rolling balls.

[0013] Preferably, it also includes an oil scraping mechanism. The oil scraping mechanism and the head cleaning mechanism are respectively located on the outside of the box and at both ends of the box. The structure of the oil scraping mechanism is the same as that of the head cleaning mechanism. The difference between the oil scraping mechanism and the head cleaning mechanism is that the inner wall of the cleaning wheel of the oil scraping mechanism is smooth.

[0014] Preferably, the cleaning wheel includes two wheel bodies, and the outer walls of the two wheel bodies are provided with slots along the circumference. One of the wheel bodies is provided with a pin at the end corresponding to the slot. The pin is fixed by a spring and the pin fastens the two wheel bodies together.

[0015] Preferably, the cleaning wheel frame is hinged to the housing, and a torsion spring is provided between the cleaning wheel frame and the housing.

[0016] Preferably, the enclosure comprises two half-enclosures, which are connected by screws to form the enclosure.

[0017] This invention, by setting up the aforementioned rope-patching trolley, enables the trolley to automatically move along the wire rope and apply oil, avoiding the problems of traditional manual oiling. It can achieve real-time maintenance of the wire rope without having to remove it, resulting in high work efficiency and ensuring maintenance effectiveness. Attached Figure Description

[0022] To clearly illustrate the technical features of this solution, the invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0023] Furthermore, in the description of this invention, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] like Figure 1-4 As shown, an automatic maintenance and inspection trolley for hydraulic lifting wire ropes includes a rectangular box 1 composed of two halves. The two halves are fastened together by screws, and can be opened by removing the screws. The box 1 has a through hole 3 for the wire rope to pass through. This through hole 3 is formed on the fastening surface of the two halves; that is, each half has a semi-cylindrical groove. When the two halves are fastened together, the two semi-cylindrical grooves combine to form a single cylindrical through hole 3. The reason for using two halves of the box 1 is to facilitate the passage of the wire rope through the through hole 3.

[0025] The housing 1 also includes a traveling mechanism 4 and an oiling assembly 7. The traveling mechanism 4 enables the device to move independently on the wire rope, while the oiling assembly 7 applies oil to the wire rope as it moves, thus maintaining the wire rope. Specifically, the traveling mechanism 4 and the oiling assembly 7 are arranged in two mounting cavities 6 within the housing 1. The traveling mechanism 4 and the oiling assembly 7 are installed in the two mounting cavities 6 respectively, spaced apart along the length of the through hole 3. When the wire rope passes through the through hole 3, it simultaneously passes through both the traveling mechanism 4 and the oiling assembly 7.

[0026] The aforementioned walking mechanism 4 specifically includes at least two clamping walking components 401, which can be two, three, four, etc., depending on the thickness of the wire rope. This embodiment describes four clamping walking components 401 as an example. The mounting cavity 6 includes two half-cavities. The four clamping walking components 401 are divided into two groups, one group is set in one half-cavity, and the other group is set in the other half-cavity. The four clamping walking components 401 are evenly spaced along the circumference of the through hole 3, and the four clamping walking components 401 form a clamping space. This clamping space coincides with the through hole 3 and is a part of the through hole 3. When the wire rope passes through the through hole 3, it also passes through this clamping space.

[0027] Each of the clamping and traveling components 401 specifically includes a fixed rod 401a and a traveling wheel 401b. The fixed rod 401a is fixed in the mounting cavity 6 along the length direction of the through hole 3, and the traveling wheel 401b is disposed on the fixed rod 401a and located on one side of the fixed rod 401a. The traveling wheels 401b of the four clamping and traveling components 401 clamp the wire rope and travel on the wire rope.

[0028] It should be understood that the aforementioned walking wheel 401b has an internal hub motor, which serves as the power drive wheel. Shaped like a drum, it can move independently on the steel cable. Furthermore, the hub motor of the walking wheel 401b is powered by the battery pack 5 inside the housing 1.

[0029] Furthermore, the traveling wheel 401b is mounted on the fixed rod 401a via a first wheel frame 401f. This first wheel frame 401f specifically includes a fixed seat and a swing connecting frame. The fixed seat can be secured to the fixed rod 401a using existing clamps. The swing connecting frame is movably mounted on the fixed seat. A torsion spring 401i is provided between the swing connecting frame and the fixed seat. The torque of the torsion spring 401i keeps the traveling wheel 401b pressed tightly against the wire rope. By using the torsion spring 401i to float the traveling wheel 401b, it is possible to always keep the traveling wheel 401b pressed tightly against the wire rope, reducing or even preventing slippage of the traveling wheel 401b.

[0030] Furthermore, the clamping and traveling assembly 401 also includes a first balance wheel 401d and a second balance wheel 401c. The first balance wheel 401d and the second balance wheel 401c are disposed on the fixed rod 401a and located on both sides of the traveling wheel 401b. Here, "both sides" refers to the length direction along the fixed rod 401a. That is, the presence of the first balance wheel 401d and the second balance wheel 401c ensures that the contact point of the wire rope in the traveling wheel 401b is always in the same position, avoiding the problem of the single traveling wheel 401b swinging on the wire rope and improving the stability of the traveling wheel 401b on the wire rope.

[0031] Furthermore, the first balance wheel 401d is fixed to the fixed rod 401a via the second wheel frame 401g, and the second balance wheel 401c is set on the fixed rod 401a via the third wheel frame 401e. The structure of the second wheel frame 401g and the third wheel frame 401e is the same as that of the first wheel frame 401f. Torsion springs 401i are also provided between the second wheel frame 401g and the fixed rod 401a, and between the third wheel frame 401e and the fixed rod 401a. At the same time, the third wheel frame 401e is arranged crosswise with the first wheel frame 401f. The first wheel frame 401f, the third wheel frame 401e and the second wheel frame 401g are connected by the connecting rod 401h. In this way, the first wheel frame 401f, the second wheel frame 401g, the third wheel frame 401e and the connecting rod 401h form an approximately hinged four-bar linkage mechanism. When the position of the first wheel frame 401f on the fixed rod 401a is changed, the position of the third wheel frame 401e also moves accordingly. Due to the presence of the connecting rod 401h, the distance between the traveling wheel 401b, the first balance wheel 401d, and the second balance wheel 401c and the fixed rod 401a changes. When the distance to the fixed rod 401a increases, the clamping space decreases, thus clamping the wire rope with a smaller diameter. When the distance to the fixed rod 401a decreases, the clamping space increases, thus clamping the wire rope with a larger diameter. The wheel frame structure described above can meet the requirements for traveling on wire ropes of different diameters and for their maintenance.

[0032] Furthermore, the structure of the aforementioned brushing component 7 specifically includes an oil tank 701, an oil channel (not shown due to viewing angle), and a flexible brushing component 702. The flexible brushing component 702 is disposed within the mounting cavity 6 inside the housing 1. The mounting cavity 6 is cylindrical in shape and includes two semi-cavities. In this embodiment, the flexible brushing component 702 is a rubber-graphene composite material, which is an oil-absorbing material. The flexible brushing component 702 is cylindrical in shape and includes two semi-cylindrical brushing blocks, which correspond to each other. The brushing blocks are inserted into the two semi-cavities by interference fit or by screws, and formed on the mating surface of the two brushing blocks through the hole 3. When the two semi-boxes are fastened together, the two semi-cylindrical brushing blocks are also fastened together on the fastening surface to form a section through the hole 3. The oil tank 701 is set in the box 1 between the two mounting cavities 6. The lubricating oil in the oil tank 701 flows to the flexible brushing component 702 through the oil passage. When the traveling wheel 401b travels on the wire rope, the flexible brushing component 702 brushes the oil on it onto the wire rope.

[0033] Furthermore, in addition to the aforementioned components, this device also includes a head cleaning mechanism 2. Specifically, the head cleaning mechanism 2 includes a cleaning wheel frame 201, a ball bearing 203, and a cleaning wheel 202. The cleaning wheel 202 has a through hole that coincides with a through hole 3, and the through hole is also for passing a steel wire rope. The inner wall of the cleaning wheel 202 has a frosted surface (similar to sandpaper). The end of the cleaning wheel frame 201 connected to the cleaning wheel 202 is U-shaped, and the lower ends of the two flanges of the U-shaped portion have upward-curved edges. These curled edges extend from the cleaning wheel 202... The two ends extend into the interior of the cleaning wheel 202. The two rolled edges are connected to the inner wall of the cleaning wheel 202 by rolling balls 203. When the wire rope passes through the cleaning wheel 202 and moves along the wire rope, the cleaning wheel 202 is passively rotated due to the wire rope lay. In order to better clean the dirt on the wire rope, the inner wall of the cleaning wheel 202 is evenly spaced along its circumference with raised textures 204 that match the wire rope lay. The raised textures 204 and the abrasive grinding surface of the inner wall of the cleaning wheel 202 are used to clean the cleaning wheel 202.

[0034] Furthermore, this device also includes an oil scraping mechanism. The oil scraping mechanism and the head cleaning mechanism 2 are respectively located on the outside of the housing 1 and at both ends of the housing 1. The structure of the oil scraping mechanism is the same as that of the head cleaning mechanism 2. The difference between the oil scraping mechanism and the head cleaning mechanism 2 is that the inner wall of the cleaning wheel 202 of the oil scraping mechanism is smooth. The oil scraping mechanism can more evenly apply the oil to the wire rope and can also prevent excessive oil from dripping from certain areas at certain moments.

[0035] Furthermore, the cleaning wheel 202 specifically comprises two semi-circular wheels. Each wheel has a slot 205 along its circumferential outer wall. One wheel has a pin 207 at the end corresponding to the slot 205. The pin 207 is secured by a spring 206, which connects the two wheels. The initial force of the spring 206 pushes the pin 207 into the slot 205, connecting the two semi-circular wheels. When a wire rope needs to be threaded through the hole, the pin 207 is manually moved to disengage from the other wheel, separating the two wheels.

[0036] Furthermore, the aforementioned cleaning wheel frame 201 is hinged to the end face of the housing 1. Specifically, a connecting rod 8 is provided at the end of the housing 1, and the end of the cleaning wheel frame 201 away from the U-shaped part is hinged to the connecting rod 8. At the same time, a torsion spring 401i is provided between the cleaning wheel frame 201 and the connecting rod 8. The presence of the torsion spring 401i can not only fix the cleaning wheel frame 201, but also give the cleaning wheel 202 a torque, so that it is in a floating state. Its floating can adapt to the situation where the wire rope has a slight bend at a certain position.

[0037] The above specific embodiments should not be construed as limiting the scope of protection of the present invention. For those skilled in the art, any alternative improvements or modifications made to the embodiments of the present invention shall fall within the scope of protection of the present invention.

[0038] Any aspects of this invention not described in detail are well-known to those skilled in the art.
