Description

Technical Field

[0001] The invention belongs to the technical field of main cable clamp sealing, and in particular relates to a rubber spring sealing strip for a main cable clamp of a suspension bridge. Background Art

[0002] Suspension bridges have been rapidly developed in modern bridges due to their beautiful appearance and large span capacity, especially in large-span bridges. Cable clamps are components that tightly clamp the main cable strands and connect the main cable with the suspenders. They mainly bear the tension of the suspenders. The structural types of cable clamps are divided into two categories: straddle type and pin-joined type. The pin-joined main cable clamps can be divided into upper and lower half pin-joined types and left and right half pin-joined types. When the two types of pin-joined cable clamps are finally installed, the two half-cable clamps are clamped to the main cable by high-strength bolts. As the core load-bearing component, the quality of the cable clamp determines the safety of the bridge, and the sealing of the cable clamp plays a vital role in the safety of the cable clamp. The existing sealing method is to apply rubber sealant or install rubber sealing strips on the docking plane of the pin-joined cable clamp, and seal the two half-cable clamps clamped on the main cable from both sides. The pin-joined cable clamp is sealed with rubber seals. When the sealant is naturally vulcanized, the deformation of the sealant is large, bubbles are easily generated during the construction process, the quality is difficult to control, the construction process is time-consuming and labor-intensive, and the service life is short, which cannot meet the requirement of high service life of the sealing strip; when the existing rubber sealing strip is used to seal the pin-connected cable clamp, the maximum compression allowed by the existing rubber sealing strip is about 30%. If an O-type or rectangular rubber sealing strip structure is used, the compression of the rubber sealing strip can reach about 57-60%, but this has greatly exceeded the allowable compression of the sealing strip, which can easily lead to compression fatigue, bulging or even rupture of the sealing strip, shortening the service life of the sealing strip, and the width of the sealing strip is more than twice the original width, which cannot meet the use requirements.

[0003] Therefore, there is a lack of a rubber spring sealing strip for the main cable clamp of a suspension bridge with a simple structure and reasonable design to solve the problems of small compression, poor sealing effect and short service life of the existing sealing structure.

[0020] 1. The invention has novel and reasonable structural design, low manufacturing cost, large compression volume, good sealing effect, long service life, and is easy to promote and apply.

[0021] 2. The present invention is provided with an elastic part, which is composed of at least two hollow elastic bodies. The compression amount of each hollow elastic body can reach 65%, and when the compression amount of the hollow elastic body reaches 65%, the hollow elastic body is only pressed together, and the hollow elastic body is not compressed and deformed, which plays a positive role in improving the service life of the rubber spring sealing strip.

The compression amount of each hollow elastomer body can reach 65%. When the compression amount of the hollow elastomer body reaches 65%, the hollow elastomer body is only pressed together, and the hollow elastomer body is not compressed and deformed, which plays a positive role in improving the service life of the rubber spring sealing strip. The compression amount is large, the sealing effect is good, and the service life is long, which is convenient for promotion and application.

[0047] The present invention is described in detail through Examples 1 to 6:

[0048] Example 1

[0049] like Figure 1 and Figure 2 As shown, the present invention includes an upper mounting portion 1 and a lower mounting portion 2, and an elastic portion arranged between the upper mounting portion 1 and the lower mounting portion 2;

[0050] The elastic part includes an upper elastic part 3 and a lower elastic part 4 which are symmetrically arranged. The upper elastic part 3 and the lower elastic part 4 have the same structure. The upper elastic part 3 includes a first elongated hollow elastic body 5 and a first blocking block 6 for blocking both ends of the first elongated hollow elastic body 5. The first blocking block 6 is located in the internal cavity of the first elongated hollow elastic body 5.

[0051] The first elongated hollow elastic body 5 comprises a hollow elastic body, which comprises an upper straight portion 5-1 and a lower straight portion 5-2, and a left arcuate portion 5-3 and a right arcuate portion 5-4 symmetrically arranged on the left and right sides of the upper straight portion 5-1. The wall thickness of the hollow elastic body is 2 mm to 3 mm, and the height of the internal cavity of the hollow elastic body is 8 mm to 10 mm. The maximum distance L1 between the left arcuate portion 5-3 and the right arcuate portion 5-4 of the hollow elastic body is greater than the length of the upper straight portion 5-1.

[0052] The upper straight portion 5-1 includes a straight portion, the left arc portion 5-3 includes a b arc portion, a c inclined portion, a d arc portion, an e inclined portion and an f arc portion connected in sequence, the lower straight portion 5-2 includes a g straight portion, the centers of the b arc portion and the f arc portion are both located outside the hollow elastic body, and the center of the d arc portion is located inside the hollow elastic body;

[0053] The upper straight portion 5 - 1 of the upper elastic portion 3 is connected to the upper mounting portion 1 .

[0054] In this embodiment, it should be noted that the upper mounting portion 1 and the lower mounting portion 2 are both rectangular structures or trapezoidal structures, the main cable clamp includes an upper half cable clamp 18 and a lower half cable clamp 19, both end surfaces of the upper half cable clamp 18 are provided with upper mounting grooves, both end surfaces of the lower half cable clamp 19 are provided with lower mounting grooves that match the upper mounting grooves, the upper mounting portion 1 is fixedly mounted in the upper mounting groove of the upper half cable clamp 18, and the lower mounting portion 2 is fixedly mounted in the lower mounting groove of the lower half cable clamp 19;

[0055] The upper straight portion 5-1 and the lower straight portion 5-2 of the hollow elastic body are arranged symmetrically, the cross section of the upper straight portion 5-1 is an inverted trapezoidal structure, and the top surface width of the upper straight portion 5-1 is 18mm to 20mm. The upper straight portion 5-1 and the lower straight portion 5-2 are arranged to facilitate the connection of multiple hollow elastic bodies, and at the same time, facilitate the connection of the hollow elastic body with other components;

[0056] The maximum distance L1 between the left arc portion 5-3 and the right arc portion 5-4 of the hollow elastic body is 28mm to 30mm, and the wall thickness of the hollow elastic body is equal at all places. By setting the left arc portion 5-3 and the right arc portion 5-4, the hollow elastic body is naturally compressed toward the arc portion d of the left arc portion 5-3 and the arc portion d of the right arc portion 5-4 after being compressed by force, thereby avoiding the problem that the circular structure deviates in an uncertain direction and causes uneven force on the elastic part. Moreover, the width of the hollow elastic body in the maximum compression state is only increased by 2mm to 3mm compared with the width of the hollow elastic body in the uncompressed state, which is within the width variation range allowed by the main cable clamp, and has good stability and good sealing effect.

[0057] The left arc portion 5-3 and the right arc portion 5-4 of the hollow elastic body both include arc segments d. The arc segments d can effectively avoid the formation of sharp corner structures on the left and right sides of the hollow elastic body when the hollow elastic body is compressed, thereby avoiding stress concentration caused by the sharp corner structures and causing cracking of the hollow elastic body after compression;

[0058] The left arc portion 5-3 and the right arc portion 5-4 of the hollow elastomer body also include an arc portion b and an arc segment f. By setting the arc portion b and the arc segment f, the left and right sides of the connection between the two adjacent hollow elastomer bodies are formed into an arc structure, thereby avoiding the formation of a sharp-angle structure on the left and right sides of the connection between the two adjacent hollow elastomer bodies when the elastic portion is compressed, thereby avoiding the stress concentration generated by the sharp-angle structure causing the connection between the two adjacent hollow elastomer bodies to crack after compression, thereby effectively extending the service life of the rubber spring sealing strip.

[0059] In this embodiment, there are two first blocking blocks 6 in the first elongated hollow elastic body 5 , and the two first blocking blocks 6 are respectively located at two ends of the first elongated hollow elastic body 5 to block the internal cavity of the first elongated hollow elastic body 5 .

[0060] In this embodiment, when the hollow elastomer body is compressed by force, the height of the internal cavity of the hollow elastomer body gradually decreases. When the inner side surface of the upper straight portion 5-1 of the hollow elastomer body and the inner side surface of the lower straight portion 5-2 are in contact with each other, the hollow elastomer body is approximately a solid structure. At this time, the compression of the hollow elastomer body can reach 65%. When the compression of the hollow elastomer body reaches 65%, the hollow elastomer body is simply pressed together, and the hollow elastomer body is not compressed and deformed, which plays a positive role in improving the service life of the rubber spring sealing strip. In special cases, the hollow elastomer body can also withstand a compression of about 20%, with a large compression amount and a long service life.

[0061] In this embodiment, in actual use, due to the limited width of the sealing plane between the upper half cable clamp 18 and the lower half cable clamp 19, it is impossible to allow the sealant or the sealing strip to deform indefinitely at the plane. The width variation allowed by the main cable clamp is generally no more than about 20% of the width of the sealing strip. When the rubber spring sealing strip of the present invention is in the maximum compression state, the width variation of the rubber spring sealing strip is about 10%, which can meet the actual requirements.

[0062] In this embodiment, in actual use, the first elongated hollow elastic body 5 of the upper elastic portion 3 and the first elongated hollow elastic body 5 of the lower elastic portion 4 are formed as one piece.

[0063] like Figure 1 As shown, in this embodiment, a first upper semicircular groove 7-1 is provided on the inner side surface of the upper straight portion 5-1 of the upper elastic portion 3, and a first lower semicircular groove 7-2 cooperating with the first upper semicircular groove 7-1 is provided on the top of the first blocking block 6, and the first upper semicircular groove 7-1 and the first lower semicircular groove 7-2 cooperate to form a first pressure-bearing hole 7.

[0064] In this embodiment, the first upper semicircular groove 7-1 on the upper elastic part 3 and the first lower semicircular groove 7-2 on the first blocking block 6 cooperate to form a first pressure-bearing hole 7, and the first pressure-bearing hole 7 is connected to the atmosphere. By setting the first pressure-bearing hole 7, a certain deformation space is provided for the hollow elastomer body. As the elastic part is compressed to a certain height, the first pressure-bearing hole 7 is gradually closed, and a certain internal pressure is naturally formed in the internal cavity of the first elongated hollow elastomer 5, so that the elastic part of the sealing strip can withstand a certain pressure, and the air pressure is evenly distributed in the internal cavity of the first elongated hollow elastomer 5, which improves the lateral rigidity and vertical rigidity of the first elongated hollow elastomer 5, and then improves the lateral rigidity and vertical rigidity of the elastic part, ensuring the sealing performance of the elastic part, and can isolate the main cable wrapped in the main cable clamp from the outside world, ensuring that the main cable will not be corroded by harmful gases such as rain and salt spray, thereby ensuring the service life of the main cable clamp and the main cable.

[0065] In this embodiment, in actual use, the radius of the first upper semicircular groove 7-1 and the radius of the first lower semicircular groove 7-2 are both smaller than the wall thickness of the hollow elastomer body, and the number of the first pressure-bearing holes 7 of the upper elastic part 3 is two. By providing two first pressure-bearing holes 7, the pressure-bearing effect of the hollow elastomer body can be guaranteed while ensuring the strength of the upper straight part 5-1 of the hollow elastomer body.

[0066] In actual use, the upper mounting portion 1 is bonded to the upper mounting groove of the upper half cable clamp 18 by an adhesive, and the lower mounting portion 2 is bonded to the lower mounting groove of the lower half cable clamp 19 by an adhesive. If the compression amount of the sealing strip is less than 50%, two first blocking blocks 6 are used to block the two ends of the first long hollow elastic body 5; when the compression amount of the sealing strip is greater than 50%, after the sealing strip is compressed into place, a sealant is used to block the two ends of the first long hollow elastic body 5, or an end face sealing block is used to seal the gap between the two end faces of the hollow elastic body 5 and the end face of the cable clamp.

[0069] In this embodiment, the width of the first notch is equal to the length of the lower straight portion 5-2 of the hollow elastomer body, and the width of the first notch is 5mm to 7mm. In actual use, the length of the lower straight portion 5-2 of the hollow elastomer body and the width of the first notch can be adjusted according to actual needs.

[0070] In this embodiment, in actual use, the first elongated hollow elastomer 5 of the upper elastic part 3 and the first elongated hollow elastomer 5 of the lower elastic part 4 are integrally formed; the first blocking block 6 of the upper elastic part 3 and the first blocking block 6 of the lower elastic part 4 are connected as a whole, and the first blocking block 6 of the upper elastic part 3 and the first blocking block 6 of the lower elastic part 4 are integrally formed.

[0071] In actual use, the upper mounting portion 1 is bonded to the upper mounting groove of the upper half cable clamp 18 by an adhesive, and the lower mounting portion 2 is bonded to the lower mounting groove of the lower half cable clamp 19 by an adhesive. If the compression amount of the sealing strip is less than 50%, two first blocking blocks 6 are used to block the first elongated hollow elastic body 5 and the two ends of the first notch on the first elongated hollow elastic body 5; if the compression amount of the sealing strip is less than 50%, after the sealing strip is compressed into place, the first elongated hollow elastic body 5 and the two ends of the first notch on the first elongated hollow elastic body 5 are blocked by a sealant, or the end face sealing block is used to seal the two end faces of the hollow elastic body 5 and the end face gap of the cable clamp together.
