Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a cable-stayed cable cleaning device which is convenient for disassembly and assembly. Background Technique

[0002] A bridge refers to a structure erected over rivers, lakes and seas to enable vehicles and pedestrians to pass smoothly. A bridge generally consists of an upper structure, a lower structure, bearings and auxiliary structures. A stay cable, also known as a cable, is the main load-bearing member that directly transfers the weight of the main girder and the bridge deck of a cable-stayed bridge to the tower. The stay cables of a cable-stayed bridge are usually made of steel cables, and their forms vary according to their composition methods, and can be composed of parallel steel wires, parallel steel cables, single steel cables, steel wire ropes, enclosed steel cables or solid steel bars. Since the stay cables are placed obliquely, they are called stay cables. A cable-stayed bridge consists of a cable tower, a main girder and stay cables. The cable tower types include A-type, inverted Y-type, H-type, and single-column, and the materials are steel and concrete. The stay cable arrangements include single cable plane, parallel double cable plane, inclined cable plane, etc.

[0003] Stay cables are usually made of steel. When exposed to harsh environmental conditions for a long time, they are attached by seawater, rainwater and pollutants in the air, and are prone to corrosion, which affects their structural strength and stability. Therefore, it is necessary to regularly clean the surface to extend their service life.

For the current cleaning method of stay cables, workers climb and clean through lifting equipment, using high-pressure water guns or cloths to wipe. However, since the stay cables are too long, the lifting machine needs to be adjusted continuously, which is not only inconvenient but also has certain safety hazards; 2. Although drones can replace manual operations, single spraying may not be able to completely remove surface stains. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by ordinary technical staff in the art without creative efforts belong to the scope of protection of the present utility model.

[0024] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a stay cable cleaning device that is convenient for disassembly and assembly, including a driving base 1. At both ends of the outer wall of the driving base 1, a first winding rod 2 is respectively installed. On one side of the driving base 1 away from its outer wall, an external fixing component 3 is provided. At both ends of the outer wall of the external fixing component 3, a second winding rod 4 is respectively installed. The first winding rods 2 are respectively installed and connected to the second winding rods 4 through steel ropes wound on their surfaces. Inside the external fixing component 3, an internal fixing component 5 is installed through bolts. On the other side of the driving base 1 away from its outer wall, a cleaning bucket 6 is provided. At both ends of the cleaning bucket 6, a sewage tank 7 and a clean water tank 8 are respectively installed.

[0025] Inside the driving base 1, a driving gear 101 is installed through a mounting frame. One end of the driving gear 101 is meshed and connected with a driven gear 102. The driven gear 102 is respectively installed and connected to the first winding rods 2 through a shaft rod penetrating through its axis.

[0026] The external fixing component 3 includes an upper base 301 and a lower base 302, and the upper base 301 and the lower base 302 are connected by a slide rod 303.

[0027] The internal fixing component 5 includes an upper stay cable patch 501 and a lower stay cable patch 502. The upper stay cable patch 501 and the lower stay cable patch 502 are bolted together through connecting pieces welded to both ends of their outer walls. The upper stay cable patch 501 and the lower stay cable patch 502 are respectively provided with an internal moving layer 503 that is slidably connected to their interiors.

[0028] The cleaning bucket 6 includes a fixing plate 601, an outer bucket 602, and an inner bucket 603. The fixing plate 601 is glued to the surface of the frame. The bottom of the outer bucket 602 is glued and connected to the top of the fixing plate 601. The inner bucket 603 is rotatably connected inside the outer bucket 602.

[0029] In this embodiment, as Figure 2 shown, a servo motor connected to the driving gear 101 is provided on the outer wall of the driving base 1, and the driven gear 102 is rotatably connected inside the driving base 1 through the driving gear 101. And the first winding rods 2 are rotatably connected to both ends of the outer wall of the driving base 1 through the driven gear 102; the rotation of the driving gear 101 and the driven gear 102 drives the first winding rods 2 at both ends to rotate, and under the connection of the steel ropes, the components for cleaning at the front end are retracted.

[0030] In this embodiment, as Figure 2As shown, both ends of the sliding rod 303 are respectively slidably connected to the through holes formed on the surfaces of the upper base 301 and the lower base 302, and an opening and closing structure is formed between the upper base 301 and the lower base 302 through the sliding rod 303; the stay cables are defined according to the design requirements of the bridge and need to meet the span and bearing capacity, so the diameters of the stay cables on the surface of each bridge are different. In order to facilitate fitting on the surface of the stay cables, the inner fixing component 5 for cleaning is adjustable, and the outer fixing component 3 is the main carrier for fixing and connecting the inner fixing component 5 and the driving base 1. The telescopic structure of the sliding rod 303 can adjust the distance between the upper base 301 and the lower base 302 to better adapt to and fix the inner fixing component 5. At the same time, most components are connected by bolts during installation, and there is no need to carry large and cumbersome installation tools during installation, reducing the load of the lifting platform and the handling problems caused by the equipment being too large.

[0031] In this embodiment, as Figure 3 shown, the upper stay cable patch 501 and the lower stay cable patch 502 are made of semi-circular metal materials, and the inner movable layers 503 are symmetrically distributed, and the inner movable layers 503 form a sliding telescopic structure in the chutes formed on the surfaces of the upper stay cable patch 501 and the lower stay cable patch 502; since the stay cable is inclined, the upper stay cable patch 501 and the lower stay cable patch 502 are respectively attached to its outer wall and sleeved on the outside. Made of metal material, it has a certain weight, and under the inclined angle itself, it will slide downward due to the influence of gravity. The added inner movable layer 503 structure can meet the use range to a greater extent, and is not restricted by the specification factors when cleaning the surfaces of stay cables with different diameters.

[0032] In this embodiment, as Figure 3 shown, a hook layer 504 is provided on the arc-shaped concave surface on the opposite side of the upper stay cable patch 501 and the lower stay cable patch 502, and a fiber cloth 505 is adhesively connected to the surface of the hook layer 504; currently, in order to clean the stay cables, a lift may be used to carry construction workers. However, when spraying or wiping the surface of the stay cables, there may be a hidden danger of the lift touching the bridge during reciprocating displacement, and there are also certain safety problems. While the upper stay cable patch 501 and the lower stay cable patch 502 fall by their own weight, the internal fiber cloth 505 slides and wipes on the surface of the stay cable, which is safer than manual work, avoids the unnecessary reciprocating displacement of the lift, and has a better cleaning effect than spraying and decontaminating by drones.

[0033] In this embodiment, as Figure 4As shown, the bottom of the inner barrel 603 is installed and connected to the output end of the servo motor provided outside through a shaft rod. A plurality of through holes are penetrated and opened on the surface of the barrel body of the inner barrel 603. A drain port for pipeline connection to the sewage tank 7 is opened on one side of the outer barrel 602. At the same time, water pumps are provided inside both the sewage tank 7 and the clean water tank 8. The fiber cloth 505 is detachable and can be reused after being cleaned, dehydrated by the inner barrel 603 after cleaning. The dust adsorbed on the surface of the cable is relatively much and the cleaning range is relatively large. For the convenience of high-altitude operation and efficient cleaning strength, the used fiber cloth 505 is processed in time to ensure the effectiveness of the surface cleaning and maintenance of the bridge cable.

[0034] The usage method and advantages of the present utility model: For this cable cleaning device that is convenient for disassembly and assembly, during use, the working process is as follows:

[0035] Such as Figure 1 、 Figure 2 、 Figure 3 And Figure 4As shown, first, when using the device, the device and the personnel are sent to the highest point of the cable by the lifting platform. Clean water or chemical reagents for professional cleaning can be poured into the interior through the water inlet at the top of the water purification tank 8. It should be noted that multiple groups of fiber cloths 505 are provided, and the effective length of the steel wire ropes on the surfaces of the first winding rod 2 and the second winding rod 4 is 350 meters. Although the inner fixing component 5 is made of metal, it has no excessive load-bearing structure, while the outer fixing component 3 is made of polypropylene. When the operator attaches the upper cable patch 501 and the lower cable patch 502 to the surface of the cable respectively, they are fixed using bolts. When fixing, for the convenience of subsequent sliding, the upper cable patch 501 and the lower cable patch 502 do not need to be tightly clamped on the outer edge of the cable, and an appropriate gap is reserved. If the diameter of the cable is too large, the fitting area can be increased by sliding and pulling the inner moving layer 503. The surface wall of the inner moving layer 503 is coated with a PTFE coating to avoid damage caused by friction to the surface of the cable during sliding. After fixing the upper cable patch 501 and the lower cable patch 502, the outer fixing component 3 is adjusted to a suitable position to be sleeved outside the inner fixing component 5, and then the outer fixing component 3 is fixed to its outside through the mounting holes at the upper and lower ends of the inner fixing component 5 using bolts. The driving power servo motor drives the driving gear 101 to rotate the driven gear 102, so that the first winding rod 2 rotates and unwinds the rope on the surface. At the same time, while the upper cable patch 501 and the lower cable patch 502 at the front end fall by their own weight, the fiber cloth 505 inside slides and wipes on the surface of the cable. When sliding to the lowest point on the surface of the cable, drive in the reverse direction. After the servo motor rotates, the first winding rod 2 rotates again to retract and reset the front-end components. When cleaning the next group of cables, the fiber cloth 505 can be replaced, and the fiber cloth 505 can be placed inside the inner barrel 603. The medium for cleaning the fiber cloth 505 is poured into the cleaning barrel 6 through the nozzle on the surface of the water purification tank 8. When dehydration of the fiber cloth 505 is required, the pipeline valve on one side of the sewage tank 7 is opened, and the servo motor drives the inner barrel 603 to rotate at a high speed. During the rotation process, the fiber cloth 505 throws the internal water molecules out to the outer barrel 602 under the action of centrifugal force, and the sewage inside the outer barrel 602 is drained out through the pressure pump.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Technical staff in this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
