Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy bridge frames, in particular to an earthquake-resistant and fracture-resistant aluminum alloy bridge frame. Background Art

[0002] Aluminum alloy cable trays feature an attractive appearance, simple structure, unique design, high load capacity, and light weight. Anodized aluminum alloy cable trays resist corrosion and electromagnetic interference, particularly shielding interference, an advantage that steel cable trays cannot match. Aluminum alloy cable trays hold significant practical value in modern industry, national defense, and high technology.

[0003] However, the existing aluminum alloy bridge frames are usually spliced together with bolts, which are rigid connections. Therefore, in the case of vibration, the connection parts are easily broken due to vibration. In Chinese patent CN218242902U, a seismic-resistant and fracture-resistant aluminum alloy bridge frame is disclosed. The connecting parts of the seismic-resistant and fracture-resistant aluminum alloy bridge frame adopt a double-layer plate structure of inner and outer outer side fixing plates and inner side fixing plates, which improves the connection strength and enhances the fracture resistance of the connection between the bridge frames. The circular screw hole plate in the connecting part is installed in the circular hole under the action of the transverse spring column and the longitudinal spring column, so that when vibration occurs, the circular screw hole plate can vibrate up and down and left and right, thereby reducing the vibration between adjacent bridge frames, buffering the vibration pressure that the connecting parts need to bear, and improving the seismic resistance of the structure. However, while solving the problem, the seismic-resistant and fracture-resistant aluminum alloy bridge frame has the following defects:

[0004] Aluminum alloy bridges are characterized by being light and thin, with a limited overall thickness. Therefore, during production, it is difficult to install spring columns and circular screw hole plates in the narrow spring slot space, which is inconvenient for production. In addition, the elastic force of the spring columns that can be installed in the narrow space is limited, resulting in insufficient elastic force and failure to achieve the purpose of buffering. Utility Model Content

[0005] The purpose of the present invention is to at least solve one of the technical defects described in the background technology.

[0006] To this end, one purpose of the present invention is to propose an earthquake-resistant and fracture-resistant aluminum alloy bridge frame, which aims to solve the problem that the earthquake-resistant and fracture-resistant aluminum alloy bridge frame in the existing technology is not easy to produce, and the elastic force of the spring columns that can be installed in the narrow space is limited and cannot achieve buffering.

[0007] In order to achieve the above-mentioned objectives, an embodiment of one aspect of the present invention provides an earthquake-resistant and fracture-resistant aluminum alloy bridge frame, including a U-shaped groove, a first positioning block is fixedly connected to both sides of the U-shaped groove, a guide cylinder is fixedly connected to one side of the first positioning block, a spring is sleeved on the outer surface of the guide cylinder, a circular ring is slidably connected to the outer surface of the guide cylinder, a plurality of connecting rods are fixedly connected to the inner wall of the circular ring, a sliding groove is provided on the outer surface of the guide cylinder, the end of the connecting rod is fixedly connected to a fixed block, a steel rope is fixedly connected to one side of the fixed block, a first through hole is provided on one side of the first positioning block, and second positioning blocks are fixedly connected to both sides of the U-shaped groove.

[0008] Preferably, any of the above schemes is that a second through hole is provided on one side of the second positioning block, a notch communicating with the second through hole is provided on the side of the second positioning block away from the U-shaped groove, a positioning groove is provided on one side of the second positioning block, and the end of the steel rope away from the fixed block is fixedly connected to the positioning block, which facilitates the connection between the steel rope and the second positioning block, thereby achieving the purpose of easy assembly.

[0009] Preferably, any of the above schemes is that both ends of the U-shaped groove are rotatably connected to the first guide wheel and the second guide wheel on both sides, and the steel rope is located between the first guide wheel and the second guide wheel to avoid friction between the steel rope and the first through hole and the second through hole, which may cause the problem of steel rope wear. In addition, when vibrating, a fulcrum is provided for the steel rope, making it easier to return the U-shaped groove.

[0010] Preferably, any of the above schemes is that a rubber plate is fixedly installed at the bottom between two adjacent U-shaped grooves, and threaded tubes are fixedly connected to the bottoms of both ends of the U-shaped grooves. Positioning holes are opened on both sides of the top of the rubber plate to block the gap at the bottom of the two adjacent U-shaped grooves to avoid exposure of the wiring harness inside the bridge frame, and the rubber plate is elastic and will not affect the seismic performance.

[0011] Compared with the prior art, the advantages and beneficial effects of the present invention are as follows:

[0012] 1. One end of the steel rope is connected to the second positioning block, and the other end of the steel rope is slidably connected to the surface of the guide cylinder on one side of the first positioning block through a circular ring, and the spring supports the circular ring to make the steel rope taut, and softly connect the two adjacent U-shaped grooves together to achieve the purpose of shock resistance and fracture resistance. Since the spring is arranged on the outside of the U-shaped groove, the operating space is large, which is convenient for production, and a spring with larger elastic force can be used as needed to ensure that the purpose of buffering can be achieved.

[0013] 2. The steel rope can be inserted into the second through hole from the notch, and when the steel rope is in a taut state, the positioning block can be inserted into the positioning groove so as not to slip out, thereby achieving the purpose of easy assembly.

[0014] 3. The first guide wheel and the second guide wheel clamp the steel rope so that when the U-shaped groove vibrates, the steel rope will not rub against the edges of the first through hole and the second through hole, thereby avoiding the problem of affecting the service life of the steel rope due to wear.

[0015] 4. During the vibration process, when the elastic force of the spring tightens the steel rope, the steel rope can use the first guide wheel or the second guide wheel as a fulcrum to provide an upward force or downward force on the edge of the U-shaped groove, so that the U-shaped groove is reset. This structural design can achieve the purpose of saving effort, thereby extending the service life of the spring.

[0016] 5. The rubber sheet can cover the bottom of the gap between two adjacent U-shaped grooves to prevent the wiring harness in the U-shaped groove from being exposed. The rubber sheet is elastic, which not only does not affect the shock resistance and fracture resistance, but also assists the spring in providing buffering force, thereby further extending the service life of the spring.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0026] The utility model provides an earthquake-resistant and fracture-resistant aluminum alloy bridge frame.

[0027] Example 1:

[0028] like Figure 1-3 As shown, it includes a U-shaped groove 1, two sides of the U-shaped groove 1 are fixedly connected to the first positioning block 2, one side of the first positioning block 2 is fixedly connected to the guide cylinder 21, the outer surface of the guide cylinder 21 is sleeved with a spring 22, the outer surface of the guide cylinder 21 is slidably connected to a ring 4, the inner wall of the ring 4 is fixedly connected to a plurality of connecting rods 41, the outer surface of the guide cylinder 21 is provided with a slide groove 23, the connecting rod 41 passes through the slide groove 23 to the inside of the guide cylinder 21, the end of the connecting rod 41 is fixedly connected to a fixed block 42, and the fixed block 42 is located in the guide cylinder 21. Inside the cylinder 21, a steel rope 43 is fixedly connected to one side of the fixed block 42, a first through hole 24 is opened on one side of the first positioning block 2, and the steel rope 43 passes through the first through hole 24 to penetrate the first positioning block 2, and the second positioning blocks 3 are fixedly connected to both sides of the U-shaped groove 1. When the two adjacent U-shaped grooves 1 are fixed, the end of the steel rope 43 away from the fixed block 42 is fixed to the second positioning block 3, and the spring 22 supports the ring 4, so that the steel rope 43 tightens the two adjacent U-shaped grooves 1, thereby achieving the purpose of soft connection.

[0029] Specifically, a cover plate 5 is fixedly installed on the top of the U-shaped groove 1. Both the U-shaped groove 1 and the cover plate 5 are made of aluminum alloy. A first bolt hole 13 is opened at the top of both ends of the U-shaped groove 1. A nut 14 is fixedly connected to the position of the inner wall of the U-shaped groove 1 corresponding to the first bolt hole 13. A second bolt hole 51 is opened at both ends of the cover plate 5. Bolts are used to pass through the second bolt hole 51 and the first bolt hole 13 and threadedly connect with the nut 14 to install the cover plate 5 on the top of the U-shaped groove 1.

[0030] Example 2:

[0031] like Figure 1-3 As shown, on the basis of embodiment one, a second through hole 31 is provided on one side of the second positioning block 3, a notch 32 which passes through the second through hole 31 is provided on the side of the second positioning block 3 away from the U-shaped groove 1, a positioning groove 33 is provided on one side of the second positioning block 3, and the end of the steel rope 43 away from the fixed block 42 is fixedly connected to the positioning block 44, and the steel rope 43 can be inserted into the second through hole 31 through the notch 32. The spring 22 pushes the ring 4 so that when the steel rope 43 is tightened, the positioning block 44 is inserted into the positioning groove 33, so that the steel rope 43 cannot slide out of the second through hole 31, thereby connecting the steel rope 43 to the second positioning block 3.

[0032] Example 3:

[0033] like Figure 1 As shown, on the basis of Example 1 or Example 2, both sides of the two ends of the U-shaped groove 1 are rotatably connected with the first guide wheel 11 and the second guide wheel 12, and the steel rope 43 is located between the first guide wheel 11 and the second guide wheel 12, and the first guide wheel 11 and the second guide wheel 12 clamp the steel rope 43. Therefore, according to the principle of two points determining a straight line, no matter how the bridge frame vibrates, the part of the steel rope 43 between the first positioning block 2 and the first guide wheel 11 is always parallel to the direction of the U-shaped groove 1, so that the steel rope 43 will not rub against the edge of the first through hole 24, thereby avoiding the problem of affecting the service life of the steel rope 43 due to wear. At the same time, during the vibration process, the spring 22 pushes the ring 4 to tighten the steel rope 43. In the process of returning the U-shaped groove 1, the steel rope 43 can provide downward pressure to the first guide wheel 11, or provide upward force to the second guide wheel 12, so that the U-shaped groove 1 is reset, and more effort is saved by doing work on the edge of the U-shaped groove 1.

[0034] Example 4:

[0035] like Figure 1 、 Figure 2 and Figure 4 As shown, on the basis of Example 1 or Example 2 or Example 3, a rubber plate 6 is fixedly installed at the bottom between two adjacent U-shaped grooves 1, and the bottoms of both ends of the U-shaped groove 1 are fixedly connected with threaded cylinders 15. Positioning holes 61 are opened on both sides of the top of the rubber plate 6. The rubber plate 6 is sleeved on the surface of the threaded cylinder 15 at the bottom of the two adjacent U-shaped grooves 1 through the positioning holes 61, and then is threadedly connected to the threaded cylinder 15 using bolts to achieve the purpose of fixing the rubber plate 6. The rubber plate 6 can block the bottom of the gap between the two adjacent U-shaped grooves 1, thereby preventing the wiring harness in the U-shaped groove 1 from being exposed, and the rubber plate 6 is elastic, which not only does not affect the shock resistance and fracture resistance, but also can assist the spring 22 in providing buffering force.

[0036] The working principle of the present invention is as follows: when in use, the U-shaped groove 1 is suspended on the top of the wall by a bridge bracket. When the building vibrates, causing the aluminum alloy bridge to vibrate, the two ends of the U-shaped groove 1 fluctuate up and down, so that the first positioning block 2 and the second positioning block 3 on the two adjacent U-shaped grooves 1 move away from each other, so the spring 22 is compressed by force. When the first positioning block 2 and the second positioning block 3 approach each other during the vibration process, the spring 22 resets, so that the steel rope 43 is always in a taut state. The two adjacent U-shaped grooves 1 are softly connected by the steel rope 43 and the spring 22 to achieve the purpose of earthquake resistance and fracture resistance.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] 1. By setting a steel rope 43, one end of the steel rope 43 is connected to the second positioning block 3, and the other end of the steel rope 43 is provided with a ring 4, the ring 4 is slidably connected to the surface of the guide cylinder 21 on one side of the first positioning block 2, and the spring 22 supports the ring 4, so that the steel rope 43 is tightened, thereby softly connecting the two adjacent U-shaped grooves 1 together to achieve the purpose of shock resistance and fracture resistance. Since the spring 22 is arranged on the outside of the U-shaped groove 1, the operating space is large, which is convenient for production, and a spring 22 with greater elastic force can be used as needed to ensure that the buffering purpose can be achieved.

[0039] 2. By providing a notch 32 that penetrates the second through hole 31 on one side of the second positioning block 3, and providing a positioning block 44 at the end of the steel rope 43, the steel rope 43 can be inserted into the second through hole 31 through the notch 32, and when the steel rope 43 is in a taut state, the positioning block 44 can be inserted into the positioning groove 33 so as not to slip out, thereby achieving the purpose of easy assembly.

[0040] 3. By setting the first guide wheel 11 and the second guide wheel 12, the first guide wheel 11 and the second guide wheel 12 clamp the steel rope 43, so that when the U-shaped groove 1 vibrates, the steel rope 43 can always be in the middle of the first through hole 24 and the second through hole 31, and will not rub against the edges of the first through hole 24 and the second through hole 31, thereby avoiding the problem of affecting the service life of the steel rope 43 due to wear.

[0041] 4. During the vibration process, when the elastic force of the spring 22 tightens the steel rope 43, the steel rope 43 can use the first guide wheel 11 or the second guide wheel 12 as a fulcrum to provide an upward force or a downward force on the edge of the U-shaped groove 1, so that the U-shaped groove 1 is reset. This structural design can achieve the purpose of saving effort, so the elastic force requirement of the spring 22 is relatively small, thereby extending the service life of the spring 22.

[0042] 5. By providing a rubber plate 6, the bottom of the gap between two adjacent U-shaped grooves 1 can be shielded, thereby preventing the wiring harness in the U-shaped groove 1 from being exposed. The rubber plate 6 is elastic, which not only does not affect the shock resistance and fracture resistance, but also assists the spring 22 in providing a buffering force, thereby further extending the service life of the spring 22.
