Description

Technical Field

[0001] The invention relates to the technical field of bridge engineering, and in particular to a bridge cable maintenance device. Background Art

[0002] Bridges are an important part of the transportation system, and their safety in various environments is very important. Most of the cable surfaces composed of the cables of cable-stayed bridges are spatial structures and are located directly above the bridge lanes. In low-temperature rainy and snowy weather, due to the effects of rain, snow and low temperatures, snow and icicles are easily formed on the cables. The presence of snow and icicles increases the deadweight of the cables and changes the cross-sectional shape of the cables. Under such conditions, the stress state of the cables themselves will change, and abnormal "ice-wrapped vibrations" are easily formed under the action of wind, which poses a huge threat to the structural safety of the bridge.

[0003] The prior art discloses a deicing device for cables of cable-stayed bridges in severe cold environments with publication number CN215210612U, which includes a casing, crushing and locking bolts. The casing includes a rear half shell and a front half shell, and crushing components, driving components and spraying components are symmetrically installed on the rear half shell and the front half shell, respectively, wherein the spraying components are located at the bottom of the rear half shell and the front half shell, and the top and bottom sides of the rear half shell and the front half shell are respectively fixedly connected to fixing plates, and connecting holes are respectively arranged in the middle of the fixing plates, and locking bolts pass through the inner sides of the connecting holes, and the locking bolts are threadedly connected to nuts.

[0004] However, the above-mentioned method still has some shortcomings in actual use: the device directly uses the crushing head to collide with the ice condensed on the rope. Although the ice is removed, large pieces of ice will fall and pose a huge threat to the safety of traffic on the bridge deck. In addition, some firmly frozen ice will remain on the surface of the cable and cannot be completely removed. Summary of the invention

[0018] Compared with the existing technology, the present invention has the following beneficial effects:

[0019] 1. Under the action of the second pulley assembly, the first motor starts the two third connecting shafts to rotate, the two third connecting shafts drive the two fifth gears to rotate, the two fifth gears mesh with the third rack, and then drive the second slider to slide on the inner wall of the working seat, so that the arc block and the cutting knife group perform a circular motion with the cable body as the center, and the cutting knife group is stepped from the outer circle to the inner circle, and the cutting knife group contacts the ice body to be cut and cuts it from the outside to the inside;

The fourth gear 29 rotates and meshes with the two fourth racks 41. The two second connecting rods 27 squeeze the two third springs 31 respectively, so that the two first sliders 35 squeeze the two second springs 30 respectively, so that the two cutting knives 11 move toward each other to cut the ice body 10, avoiding the large-scale falling of the ice body 10 when the cutting structure 102 is working, which poses a huge threat to the safety of traffic on the bridge deck. When the cutting structure 102 is in continuous operation, the second rack 28 is away from the first gear 12. Under the action of the second spring 30 and the third spring 31, the cutting knife 11 returns to its original state. The cutting knife group 17 is stepped from the outer circle to the inner circle. The cutting knife group 17 contacts the cut ice body 10 and cuts it from the outside to the inside.

[0041] Among them, the inner wall of the working seat 8 is fixedly connected with the first rack 19, and the first rack 19 is meshingly connected with the second gear 20.

[0042] In this embodiment, when the arc block 16 and the cutting tool group 17 perform circular motion with the cable body 3 as the center, the second gear 20 meshes with the first rack 19, and the rotation of the second gear 20 drives the scraper wheel 18 to rotate, thereby further removing the ice body 10 remaining on the outer wall of the cable body 3. At the same time, under the action of the three groups of first pulley assemblies 39, the scraper wheel 18 is ensured to continue working, so that the ice body 10 remaining on the outer wall of the cable body 3 can be cleaned up.

[0044] Among them, the crushing structure 103 also includes two second sliders 43, two first connecting rods 24 and two first springs 25, the outer walls of the two third connecting shafts 38 are respectively fixedly connected with protrusions 34, the two second sliders 43 are slidably connected to the inner wall of the lower shell 2, one end of the two first springs 25 are respectively fixedly connected to the outer walls of the two second sliders 43, the other ends of the two first springs 25 are both slidably connected to the inner wall of the lower shell 2, one end of the two first connecting rods 24 are respectively fixedly connected to the outer walls of the two second sliders 43, and the other ends of the two first connecting rods 24 are respectively fixedly connected to the two fifth racks 42.

[0045] In this embodiment, the two third connecting shafts 38 rotate to drive the two protrusions 34 to rotate respectively, and the two protrusions 34 rotate intermittently to push the two second sliders 43 to squeeze the two first springs 25 respectively, so that the two second sliders 43 move downward on the inner wall of the lower shell 2, and the two second sliders 43 move downward to drive the two first connecting rods 24 to move downward respectively, and the two first connecting rods 24 move downward so that the two fifth racks 42 are respectively meshed with the two third gears 23, and the two third gears 23 rotate to drive the four I-shaped wheels 22 to rotate, and the four I-shaped wheels 22 rotate to release the four traction lines 26. Under the action of the four fourth springs 32, the two squeezing plates 15 quickly slide toward each other on the inner walls of the filter housing 7 and the lower housing 2, so that the outer walls of the two squeezing plates 15 crush the large ice blocks 10 introduced through the two inclined plates 9, and all the cut ice blocks 10 are fragmented, effectively avoiding the large ice blocks 10 from falling from a high altitude and posing a huge threat to the safety of traffic on the bridge deck.

[0046] Working principle: When in use, first manually remove the ice body 10 at the bottom of the bridge cable body 3 so that the equipment can be installed on the cable and ensure that when it moves forward, the cutting structure 102 starts working only after the transverse cutting structure 101 completes an action. First, use the bolt assembly to put the equipment on the cable body 3, and then turn on the external power supply of the electric telescopic rod 4. Under the action of the fixed rod 5, the four rotating plates 45 are driven to rotate toward the working seat 8, so that the four moving wheels 47 are close to the cable body 3, and the equipment is in a standby state, the cutting knife 11 is away from the ice body 10, and the two extrusion plates 15 are away.

[0047] The external power supply of the second motor 46 is turned on to drive the moving wheel 47 to rotate on the cable body 3, so that the device moves. At the same time, the external power supply of the first motor 13 is turned on to operate the cutting structure 102, and the transverse cutting structure 101 cuts the ice body 10. That is, under the action of the second pulley assembly 44, the start of the first motor 13 drives the two third connecting shafts 38 to rotate, and the two third connecting shafts 38 drive the two fifth gears 33 to rotate, and the two fifth gears 33 mesh with the third rack 36, thereby driving the second slider 43 to slide on the inner wall of the working seat 8, so that the arc block 16 and the cutting tool group 17 perform a circular motion with the cable body 3 as the center. When the second rack 28 meshes with the first gear 12, the first gear 12 The fourth gear 29 is driven to rotate, and the fourth gear 29 rotates and meshes with the two fourth racks 41. The two second connecting rods 27 squeeze the two third springs 31 respectively, so that the two first sliders 35 squeeze the two second springs 30 respectively, so that the two cutting knives 11 move towards each other to cut the ice body 10, avoiding the large-scale falling of the ice body 10 when the cutting structure 102 is working, which poses a huge threat to the safety of bridge deck driving. When the cutting structure 102 is in continuous operation, the second rack 28 is away from the first gear 12. Under the action of the second spring 30 and the third spring 31, the cutting knife 11 returns to its original state, and the cutting knife group 17 is stepped from the outer circle to the inner circle. The cutting knife group 17 contacts the cut ice body 10 and cuts it from the outside to the inside.

[0048] When the arc block 16 and the cutting tool group 17 perform circular motion with the cable body 3 as the center, the second gear 20 meshes with the first rack 19, and the rotation of the second gear 20 drives the scraper wheel 18 to rotate, thereby further removing the ice body 10 remaining on the outer wall of the cable body 3. At the same time, under the action of the three groups of first pulley assemblies 39, the scraper wheel 18 is ensured to be able to work continuously, so that the ice body 10 remaining on the outer wall of the cable body 3 can be cleaned up.

[0049] At the same time, the two third connecting shafts 38 rotate and respectively drive the two protrusions 34 to rotate. The two protrusions 34 rotate intermittently and respectively push the two second sliders 43 to squeeze the two first springs 25, so that the two second sliders 43 move downward on the inner wall of the lower shell 2. The two second sliders 43 move downward and respectively drive the two first connecting rods 24 to move downward. The two first connecting rods 24 move downward so that the two fifth racks 42 respectively mesh with the two third gears 23. The two third gears 23 rotate and drive the four I-shaped wheels 22 to rotate. The four I-shaped wheels 22 rotate to release the four traction lines 26. Under the action of the four fourth springs 32, the two squeezing plates 15 quickly slide toward each other on the inner walls of the filter housing 7 and the lower housing 2, so that the outer walls of the two squeezing plates 15 crush the large ice bodies 10 introduced through the two inclined plates 9, and all the cut ice bodies 10 are fragmented, effectively preventing the large ice bodies 10 from falling from a high altitude and posing a huge threat to the safety of traffic on the bridge deck. When the protrusion 34 does not squeeze the second slider 43, under the action of the two first springs 25 and the four fourth springs 32, the two squeezing plates 15 move away, and the fragmented ice bodies 10 are discharged through the filter holes 14.

[0050] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
