Description

Technical Field

[0001] The invention belongs to the technical field of cleaning inclined cables, and in particular relates to a cleaning device for bridge inclined cables. Background Art

[0002] A cable-stayed bridge is a type of bridge in which the main beam is directly pulled on the bridge tower by many cables. It is a structural system composed of pressure-bearing towers, tensioned cables and bending beams. It can be regarded as a multi-span elastically supported continuous beam with cables replacing piers. It can reduce the bending moment in the beam body, lower the building height, reduce the structural weight and save materials. A cable-stayed bridge is mainly composed of cable towers, main beams and cables. The maintenance and care of cable-stayed bridges in the later stage is an important task to ensure their structural safety and extend their service life. Cleaning the cables is an important part that cannot be ignored. In the later stage, it is necessary to conduct regular visual inspections of the cables to determine whether there is obvious dirt, rust or other damage. The cleaning method can be selected from water flushing, chemical cleaning agents and other methods. After each cleaning, make detailed records, including cleaning time, method, cleaning agent used and problems found, and form a report for filing to facilitate future maintenance and management. Through scientific and reasonable cleaning and maintenance, the service life of the cables can be effectively extended to ensure the safe operation of the bridge.

[0003] Currently, the cleaning of bridge cables is mostly done manually. During the cleaning process, workers need to take protective safety measures and move along the direction of the cables to clean. Although manual cleaning is very effective, it also leads to low cleaning efficiency and a high risk factor. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a bridge cable cleaning device.

[0005] The technical solution adopted to solve the above technical problems is: to provide a bridge cable cleaning device, comprising a bridge body, a supporting bridge tower is arranged at the center of the bridge body, a cable assembly is arranged between the top of the bridge body and both sides of the supporting bridge tower, and a device driving mechanism is fixedly connected to the front end surface of the supporting bridge tower; A rope connection sleeve is installed at one end of the equipment driving mechanism, and a connecting frame mechanism is fixedly connected to the other side of the rope connection sleeve. A limited rotation mechanism is installed on the connecting frame mechanism, and a cleaning mechanism is installed inside the limited rotation mechanism.

[0006] Furthermore, the equipment driving mechanism includes a long protective shell fixedly connected to the front end face of the supporting bridge tower, both sides of the long protective shell are rotatably connected with side sealing rotating strips, the top of the inner wall of the long protective shell is provided with a guide roller, the bottom end of the interior of the long protective shell is rotatably connected with a winding roller, one side of the bottom of the inner wall of the long protective shell is fixedly connected to a limiting rod, a transmission rope is provided between the winding roller, the guide roller and the rope connecting sleeve, and a first motor assembly is provided at the front end of the bottom of the long protective shell, and the output end of the first motor assembly is fixedly connected to a square connecting plug.

[0007] Through the above technical solution, the side sealing rotating strips on both sides are opened, the end of the transmission rope on the limit rod is removed and pulled, and connected to the installed rope connecting sleeve. At the same time, a square connecting block is installed on the output end of the first motor assembly, and then the square connecting block is inserted into the square hole at the front end of the winding roller. The first motor assembly drives the winding roller to rotate through the square connecting block, continuously pulling the transmission rope, and then driving the overall connecting frame mechanism to move along the trajectory of the steel cable in the inclined cable assembly, thereby realizing the drive of the cleaning route.

[0008] Furthermore, a square hole corresponding to the square connecting plug is opened in the center of the front end face of the winding roller, and the long protective shell, two side sealing rotating strips, guide rollers, winding rollers, limit rods and transmission ropes are always installed on the supporting bridge tower.

[0009] Through the above technical solution, during normal times, the other end of the transmission rope is wound around the limit rod, and the two side sealing rotating strips are closed, and the equipment driving mechanism abandons the first motor assembly and the square connecting plug and is fixed on the supporting bridge tower for a long time.

[0010] Furthermore, the connecting frame mechanism includes a first semicircular frame and a second semicircular frame that are rotatably connected, two transmission threaded rods are spirally connected to both sides of the first semicircular frame, one end of each of the transmission threaded rods is rotatably connected to a limiting roller, fixing ears are fixedly connected to the centers of the inner walls of both sides of the first semicircular frame, bolt assemblies are fixedly connected to both sides of the first semicircular frame at one end away from the second semicircular frame, one end of each of the two sides of the second semicircular frame is fixedly connected to an integrated open locking piece corresponding to the bolt assembly, a battery assembly is fixedly connected to one side of the interior of the second semicircular frame, a liquid storage tank is fixedly connected to the bottom of the second semicircular frame, a micro pump is installed on one side of the liquid storage tank, an annular hard pipe is fixedly connected to the output end of the micro pump, a fixing piece is installed between the second semicircular frame and the bottom of the annular hard pipe, and a plurality of long nozzles are fixedly connected to the inner wall of the annular hard pipe.

[0011] Through the above technical scheme, the first semicircular frame and the second semicircular frame are rotated and merged to achieve sleeve connection on the outside of the overall cleaning mechanism. During the rotation and merging process, the annular hard pipe can be bent outward by a certain angle to avoid jamming during the merging, and then the locking and fixing are completed by two bolt assemblies and corresponding two integrated opening locking pieces. During the installation process, multiple transmission threaded rods are rotated to make multiple limit rollers close to the inclined cable assembly until the grooves of the limit rollers and the steel cables in the inclined cable assembly are completely fitted, thereby achieving the support of the overall equipment, so that the steel cables in the inclined cable assembly are located in the center of the cleaning mechanism. During the cleaning work, the micro pump extracts the cleaning liquid from the liquid storage tank, and sprays the cleaning liquid on the surface of the steel cables of the inclined cable assembly through the annular hard pipe and multiple long nozzles. After cleaning by the cleaning mechanism, most of the sewage will flow down along the inclined cable assembly and can be collected.

[0012] Furthermore, the limit rotation mechanism includes an adjusting threaded rod rotatably connected to the connecting frame mechanism, both sides of the adjusting threaded rod are spirally connected with threaded blocks, the bottoms of the two threaded blocks are respectively fixedly connected to the first outer ring and the second outer ring, the insides of the first outer ring and the second outer ring are respectively rotatably connected with the first inner ring and the second inner ring, the outer walls of the first outer ring and the second outer ring are fixedly connected to two limit frames, one side of the second inner ring is fixedly connected to an arc gear frame, the inner wall of the arc gear frame is fixedly connected to a plurality of limit plug plates, the other side of the arc gear frame is fixedly connected to two first threaded rods, an arc sleeve tooth is sleeved between the two first threaded rods, the two first threaded rods are spirally connected with a first locking nut, the bottom of the outer wall of the second outer ring is fixedly connected to the second motor assembly, and the output end of the second motor assembly is fixedly connected to a driving gear.

[0013] Through the above technical scheme, during the installation process, the first inner ring, the second inner ring and the arc-shaped sleeve gear need to be rotated and adjusted so that their openings coincide with the openings of the first outer ring, the second outer ring and the arc-shaped gear frame respectively, to ensure that the inclined cable assembly can pass through the process of merging the first semicircular frame and the second semicircular frame, wherein during the rotation adjustment process of the arc-shaped sleeve gear, the two first locking nuts need to be loosened first, the arc-shaped sleeve gear is pulled apart, the meshing with the driving gear is released, and then the rotation adjustment is performed. After the first semicircular frame and the second semicircular frame are merged, the rotation adjustment threaded rod drives the two threaded blocks to approach each other, and then the first outer ring and the second outer ring are driven to approach each other through the two threaded blocks. The arc gear rack and the arc gear rack are fixed with the arc gear rack through two first locking nuts. The second motor assembly and the micro pump are connected to the battery assembly through wires, and the second motor assembly and the battery assembly can be connected by spiral wires, so as to meet the requirement that the distance between the battery assembly and the second motor assembly is lengthened when the first semicircular frame and the second semicircular frame are opened.

[0014] Furthermore, the spiral directions of the threads on both sides of the adjusting threaded rod are opposite, lubricating oil is filled between the first outer ring and the first inner ring and between the second outer ring and the second inner ring, and the outer tooth structure of the gear ring and the arc-shaped sleeve tooth on one side of the arc-shaped gear rack is the same.

[0015] Through the above technical scheme, it is ensured that the two threaded blocks can move in opposite directions at the same time during the rotation of the adjusting threaded rod, ensuring that relative rotation can occur between the first outer ring and the first inner ring and between the second outer ring and the second inner ring. At the same time, the outer tooth structure of the gear ring and the arc-shaped sleeve tooth on one side of the arc-shaped gear rack is the same, ensuring that the arc-shaped sleeve tooth can fill the gap of the arc-shaped gear rack through rotation adjustment.

[0016] Furthermore, the cleaning mechanism includes two groups of integrally-mounted beveled and thickened ring plates respectively arranged on the inner walls of the first inner ring and the second inner ring, an arc shell plate is fixedly connected between the two groups of the integrally-mounted beveled and thickened ring plates, a plurality of snap-fit ​​plug-in block assemblies are fixedly connected to one side of the inner walls of the two arc shell plates, a built-in arc plate is snapped into the interior of the two arc shell plates, a plurality of second threaded rods are fixedly connected to the outer walls of the two built-in arc plates, a second locking nut is spirally connected to the plurality of second threaded rods, and a plurality of brush assemblies are fixedly connected to the inner walls of the two built-in arc plates.

[0017] Through the above technical solution, when the bridge cable-stayed assembly needs to be cleaned, different multiple brush assemblies are installed according to the diameter of the steel cable of the cable-stayed assembly to ensure that the brushes inside the multiple brush assemblies can be close to the surface of the steel cable, and the multiple second threaded rods on the multiple brush assemblies are passed through the built-in arc plate, and then the second locking nuts are installed on the second threaded rods one by one, and the two built-in arc plates are rotated to be sleeved on the steel cables in the cable-stayed assembly that needs to be cleaned. During the cleaning process, the steel cables in the cable-stayed assembly are cleaned by rotating the multiple brush assemblies in conjunction with the cleaning liquid.

[0018] Furthermore, the plurality of engaging block assemblies and the plurality of limiting plug plates correspond one to one, and the length of the brushes inside the multiple brush assemblies decreases step by step.

[0019] Through the above technical scheme, it is ensured that after multiple locking block assemblies and multiple limit plug plates are inserted, the overall cleaning mechanism and the second inner ring, the arc-shaped gear rack and the arc-shaped sleeve teeth can rotate simultaneously, and the brushes in the multiple brush assemblies become shorter step by step, thereby achieving multi-layer cleaning. The long-bristled brush can perform preliminary cleaning of the surface dust, and the short-bristled brush can increase the brushing force and improve the cleaning efficiency.

[0020] The beneficial effects of the present invention are as follows: (1) The present invention designs a partial equipment driving mechanism on the supporting bridge tower. During use, the entire cleaning work can be driven by only the first motor assembly and the square connecting plug block, and in conjunction with the connecting frame mechanism, the limiting rotation mechanism and the cleaning mechanism, so that the cleaning equipment can move along the trajectory of the inclined cable to perform step-by-step cleaning, avoiding manual cleaning, greatly improving the safety of cleaning the inclined cable, and also improving the cleaning efficiency; (2) The present invention designs a first semicircular frame and a second semicircular frame combined in the connecting frame mechanism, and designs the first outer ring and the first inner ring, the second outer ring and the second inner ring in the limiting rotation mechanism with the arc gear rack and the arc sleeve gear. While ensuring that the connecting frame mechanism can pass through the inclined cable through the gaps of multiple components to complete the connection between the inclined cable and the cleaning mechanism, the arc gear rack and the arc sleeve gear can also rotate and merge a complete gear to achieve a complete rotation process, thereby achieving complete cleaning of the inclined cable.

During the rotation adjustment of the arc-shaped gear rack 711, it is necessary to first loosen the two first locking nuts 712, pull the arc-shaped gear rack 711 apart, and release the meshing with the driving gear 714, and then perform rotation adjustment. The first semicircular frame 601 and the second semicircular frame 602 are rotated and merged to achieve sleeve connection on the outside of the overall cleaning mechanism 8, and then the two bolt assemblies 606 and the corresponding two integrated open locking pieces 607 are used to complete the locking and fixing, and finally the adjusting threaded rod 701 is rotated to drive the two threaded blocks 702 to approach each other, and then the first outer ring 703 and the second outer ring 704 are driven to approach each other through the two threaded blocks 702, until the inner walls of the first inner ring 705 and the second inner ring 706 that move accordingly are tightly fitted to the outer walls of the integrated inclined thickened ring plate 802 on both sides of the cleaning mechanism 8, thereby completing The cleaning mechanism 8 is locked and fixed, and at this time, multiple limit plug plates 709 are also inserted into the corresponding engaging plug block assemblies 803. The first inner ring 705 and the second inner ring 706 can drive the cleaning mechanism 8 to rotate through the friction and engaging limit plug plates 709 and the engaging plug block assemblies 803. Finally, the arc-shaped sleeve teeth 711 are rotated and adjusted so that the arc-shaped sleeve teeth 711 can fill the gap of the arc-shaped gear frame 708, and the arc-shaped sleeve teeth 711 need to be able to mesh with the driving gear 714, and then the arc-shaped gear frame 708 and the arc-shaped sleeve teeth 711 are fixed through the two first locking nuts 712; Finally, open the side sealing rotating strips 402 on both sides, remove the end of the transmission rope 406 on the limit rod 405 and pull it to connect it to the installed rope connecting sleeve 5, and then rotate the multiple transmission threaded rods 603 to make the multiple limit rollers 604 close to the inclined cable assembly 3, until the grooves of the limit rollers 604 and the steel cables in the inclined cable assembly 3 are completely fitted, thereby achieving the support of the entire equipment, so that the steel cables in the inclined cable assembly 3 are located at the center of the cleaning mechanism 8, and at the same time, install the square connection plug 408 on the output end of the first motor assembly 407, and then insert the square connection plug 408 into the square hole at the front end of the winding roller 404, and all work preparations are completed; The first motor assembly 407 is started to drive the winding roller 404 to rotate through the square connecting plug block 408, and the transmission rope 406 is continuously pulled, thereby driving the overall connection frame mechanism 6 to move along the trajectory of the steel cable in the inclined cable assembly 3 under the support of multiple limit rollers 604. At the same time, the micro pump 610 extracts the cleaning liquid in the liquid storage tank 609, and sprays the cleaning liquid on the surface of the steel cable of the inclined cable assembly 3 through the annular hard pipe 611 and multiple long nozzles 613. The second motor assembly 713 drives the driving gear 714 to rotate, and the cleaning liquid is removed. The arc-shaped gear rack 708 and the arc-shaped sleeve tooth 711 meshing therewith are driven to rotate by driving the second inner ring 706 to drive the overall cleaning mechanism 8 to rotate, so that the multiple brush assembly 807 can rotate to clean the steel cables in the inclined cable assembly 3, and the brushes in the multiple brush assembly 807 become shorter step by step, thereby achieving multi-layer cleaning and improving the cleaning efficiency. Most of the sewage will flow down along the inclined cable assembly 3 and can be collected. At the same time, when cleaning the inclined cable assembly 3 on the other side, it is only necessary to pull the transmission rope 406 to the other side.
