Description

Technical Field

[0001] The utility model relates to the technical field of bridge cable brackets, in particular to a retractable cable bracket. Background Art

[0002] Bridges generally refer to structures built across rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology, or meet other transportation needs to make passage more convenient. In order to adapt to the thermal expansion and contraction of bridge building materials caused by factors such as temperature, load, and wind, it is often necessary to divide the bridge into multiple evenly arranged bridge decks during the construction process of the bridge. Expansion joints are set between two adjacent bridge decks to meet the thermal expansion and contraction requirements of the bridge.

[0003] For cables installed on the bridge body, when the adjacent walls expand or contract due to factors such as temperature and wind, the cable brackets fixed on the bridge decks in the prior art will continuously pull and tug on the cable body as they move between the adjacent bridge decks, which can easily cause damage or breakage on the surface of the cable body. In severe cases, it may even cause the cable body to break. Therefore, it is necessary to design a retractable cable bracket to solve the above problem. Utility Model Content

[0025] Reference Figure 1-Figure 3 , which is an embodiment of the utility model, provides a retractable cable bracket, including: a main frame unit 100 and a retractable adjustment unit 200.

[0026] The main frame unit 100 includes a sliding end frame 101 installed on one bridge deck, and an angle frame 102 and a fixed end frame 103 fixedly installed on an adjacent bridge deck. The angle frame 102 is fixedly connected to the bridge deck through a reinforcing support frame 106, and the reinforcing support frame 106 is fastened to the bridge deck through fastening bolts. The setting of the reinforcing support frame 106 enhances the connection stability between the angle frame 102 and the bridge. The sliding end frame 101, the angle frame 102 and the fixed end frame 103 are all welded with channel steel, and the channel steel is galvanized steel, which is corrosion-resistant. The corrosion resistance is improved, and it can work in high temperature, high humidity and strong ultraviolet environment, thereby extending the service life of the moving end frame 101, the angle frame 102 and the fixed end frame 103. The angle frame 102 is located between the sliding end frame 101 and the fixed end frame 103. The sliding end frame 101, the angle frame 102 and the fixed end frame 103 are jointly provided with a plurality of cable bodies 105. The plurality of cable bodies 105 and the sliding end frame 101, the angle frame 102 and the fixed end frame 103 are fixedly connected with the cable bodies 105 through a plurality of groups of evenly distributed cable jackets 104.

[0027] The telescopic adjustment unit 200 includes a first hinged frame 201 hingedly mounted on an end of the angle frame 102 away from the sliding end frame 101 and a second hinged frame 211 rotatably mounted on an end of the fixed end frame 103. The end of the second hinged frame 211 away from the fixed end frame 103 is hinged to the angle frame 102. The hinges of the first hinged frame 201 and the second hinged frame 211 are both fixedly supported by an elastic support plate 202. The elastic support plate 202 is away from the first hinged frame 201 and the second hinged frame 211. A tightening roller 204 is rotatably installed at the hinge, and symmetrically positioned fixing ears 203 are fixedly installed at the hinge of the elastic support plate 202 away from the first hinge frame 201 and the second hinge frame 211. Each pair of fixing ears 203 is rotatably connected to the corresponding tightening roller 204. Through the coordinated use of the fixing ears 203 and the tightening roller 204, the tightness adjustment range of the elastic support plate 202 and the tightening roller 204 on the cable body 105 is improved, and the tightening roller 204 is abutted against multiple cable bodies 105.

[0028] A plurality of sets of symmetrical fixed rods 205 are fixedly installed on one side of the first articulated frame 201 and the second articulated frame 211 near the cable body 105. A fixed roller 206 is rotatably installed at the lower end of each set of fixed rods 205, and an arched compression sleeve 207 is slidably sleeved on the upper end of each set of fixed rods 205. Each pair of arched compression sleeves 207 is rotatably connected to a corresponding compression roller 209. Each pair of arched compression sleeves 207 is rotatably connected to the corresponding compression roller 209 through a corresponding connecting rotating column 208. The clamping roller 209 and the corresponding fixed roller 206 are arranged on both sides of the cable body 105, and the corresponding limiting nut 210 is threadedly connected to the fixed rod 205, and a clamping spring is sleeved on the fixed rod 205, and the two ends of the clamping spring are respectively against the limiting nut 210 and the arched clamping sleeve 207; through the coordinated use of the clamping spring, the limiting nut 210 and the arched clamping sleeve 207, it can be adaptively ensured that the clamping roller 209 always maintains a good clamping effect on the cable body 105.

[0029] During use, when adjacent bridge decks move to both sides due to factors such as temperature and wind, the first articulated frame 201 and the second articulated frame 211 are compressed downward, and the originally supported cable body 105 is driven by the cooperation of the fixed pressure roller 206, the clamping roller 204 and the tensioning roller 209 to unfold the cable body 104 to adapt to the expansion amount between adjacent bridge decks. When adjacent bridge decks are relatively close due to factors such as temperature and wind, the first articulated frame 201 and the second articulated frame 211 are propped up to ensure that the cable body 105 is always in a taut state, effectively solving the defect of surface damage and breakage of the cable body 105 due to the expansion or contraction of the adjacent bridge decks.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
