Description

Technical Field

[0001] The utility model relates to the technical field of bridge cables, in particular to a device for deicing the surface of an inclined cable. Background Art

[0002] Cable-stayed bridges are currently widely used in the field of bridge construction in my country. For example, the Hangzhou Bay Bridge, the Wuhan Chuankou Yangtze River Bridge, the Sutong Yangtze River Highway Bridge, etc. all use cable-stayed bridges. The cable is the main load-bearing and force-transmitting component of the cable-stayed bridge. During the operation of the cable-stayed bridge, due to rain, snow, icing and other phenomena caused by climatic reasons, especially in the Yangtze River basin, the rain and snow left on the cable condense into ice. In addition to damaging the cable structure, when the temperature rises, the wind blows, or the cable vibrates normally, icicles and ice cones may fall from the cable. When ice blocks in a higher position fall at a higher speed, they will cause major safety hazards to vehicles traveling normally on the bridge deck. In serious cases, it may even cause a series of traffic accidents, causing significant personal and property losses.

[0003] For example, a de-icing device for bridge cables disclosed in a Chinese patent document (publication number: CN117753705A) uses a steel wire rope extended from a rope retractor to pull the de-icing device to move, and the driving force is sufficient to prevent the de-icing device from being unable to move effectively after the cable is frozen. At the same time, a heating mechanism is provided to increase the temperature of the cable and soften the ice layer, which is conducive to more efficient de-icing by the subsequent de-icing mechanism. An adjustable de-icing knife is provided so that the de-icing knife can better fit the ice layer, thereby improving the de-icing effect and de-icing efficiency.

[0004] However, the rotation of the drum scrapes the ice layer through the de-icing blade. When the ice layer is thick, the outer layer of the ice layer will melt after being heated by the heating mechanism, so the surface of the ice layer is relatively smooth. At this time, the rotation of the de-icing blade scrapes the smooth surface of the ice layer, which will make the de-icing time-consuming, thereby leading to the problem of low de-icing efficiency.

[0026] An ice-breaking device is provided on the outer surface of the ice-breaking cone 4 , and the ice-breaking device includes a connecting rod 7 , one end of which is fixedly connected to the outer surface of the ice-breaking cone 4 .

[0027] The outer surface of the connecting rod 7 is provided with a sliding sleeve 71 through a bearing. The inner wall of the movable sleeve 1 is provided with an annular groove 72. The inner wall of the annular groove 72 is slidably connected with an arc-shaped slider 73 distributed in an annular array. The inner side surfaces of multiple arc-shaped sliders 73 are fixedly connected to a rotating sleeve 74. The coordinated use of the arc-shaped slider 73 and the annular groove 72 plays a role in enabling the rotating sleeve 74 to rotate stably. The outer surface of the rotating sleeve 74 is rotatably sleeved with the inner wall of the movable sleeve 1. The outer surface of the rotating sleeve 74 is fixedly sleeved with an outer gear ring 75. The rotating sleeve 74 is connected and fixed by two semicircular sleeves through bolts, so as to facilitate installation with the inclined cable. The outer gear ring 75 is spliced ​​by two semicircular gear rings. The inner wall of the rotating sleeve 74 is fixedly connected with an L-shaped fixing block 76. The upper surface of the L-shaped fixing block 76 is fixedly connected with an extrusion inclined rod 77. The sliding sleeve 71 reduces the friction of contact with the extrusion inclined rod 77 through rotation.

[0028] The outer surface of the extrusion diagonal rod 77 contacts the outer surface of the sliding sleeve 71, and a servo motor 78 is fixedly installed on the outer surface of the movable sleeve 1 through a mounting seat. The output shaft of the servo motor 78 is fixedly installed with a rotating shaft 79 through a coupling. A driving gear 710 is fixedly sleeved on the outer surface of one end of the rotating shaft 79. The tooth surface of the driving gear 710 meshes with the tooth surface of the outer gear ring 75. The servo motor 78 drives the driving gear 710 to rotate through the rotating shaft 79, and the rotation of the driving gear 710 drives the meshing outer gear ring 75 to rotate.

[0029] By setting up an ice-breaking device, the ice on the surface of the inclined cable can be heated and softened, and then the softened ice layer is repeatedly struck so that the ice layer breaks into blocks and falls off, which greatly improves the de-icing efficiency of the inclined cable surface.

[0030] Working principle: Step 1, when deicing, install the movable sleeve 1 and the rotating sleeve 74 on the outside of the inclined cable, then start the arc heating block 2 to heat and soften the ice layer on the surface of the inclined cable, and then drive the movable sleeve 1 to move along the inclined cable through the external rope collector and the wire rope. When moving, start the servo motor 78, and the servo motor 78 drives the driving gear 710 to rotate through the rotating shaft 79. The rotation of the driving gear 710 drives the rotating sleeve 74 to rotate through the meshing outer gear ring 75. The rotation of the rotating sleeve 74 is stably rotated through the cooperation of multiple arc sliders 73 and the annular slide groove 72;

[0031] In step 2, the rotation of the rotating sleeve 74 drives the extrusion oblique rod 77 to rotate in a circle through the L-shaped fixed block 76. The rotation of the extrusion oblique rod 77 will squeeze the sliding sleeve 71. When the sliding sleeve 71 is squeezed by the extrusion oblique rod 77, it rotates through the cooperation of the bearing, thereby reducing the contact friction. At the same time, the sliding sleeve 71 drives the icebreaker cone 4 to move through the connecting rod 7. The extrusion movement of the icebreaker cone 4 drives the reset spring 6 to stretch through the block 5. When the extrusion oblique rod 77 rotates and disengages from the sliding sleeve 71, the elastic force of the reset spring 6 drives the icebreaker cone 4 to reset, thereby knocking and breaking the softened ice layer on the surface of the inclined cable.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.
