Description

A half-riding type suspension bridge cable clamp device

technical field

The utility model relates to a cable clamp device of a suspension bridge in bridge engineering, in particular to a half-riding type suspension bridge cable clamp device.

Background technique

Suspension bridges are widely respected in the field of long-span bridges and urban landscape bridges because of their unique advantages of clear force, strong spanning ability, beautiful appearance and magnificent momentum. The dead weight of the main girder and the vehicle load of the suspension bridge are all transmitted to the main cable through the suspension cable, and the effectiveness of the transmission is realized by the reasonable setting of the cable clamp. Therefore, the reliability of the cable clamp structure directly affects the safety of the entire suspension bridge. .

Although according to the function of use, the cable clamps in the suspension bridge also include the tightening cable clamps for the main cable shaping, and the closed cable clamps for the protection and sealing of the main cable saddle and the outlet of the anchorage, the cable clamps mentioned in this utility model only refer to The number of sling clips connecting the main cable and the slings is much more than the other two types of clips.

According to the different connection methods of the sling on the cable clip, the cable clip can be divided into two types: straddle type and pin hinge type. The straddle-type cable clip is slotted at the top of the cable clip, the sling is stuck in the slot and crosses the cable clip, and the two ends of the sling are connected at the beam part. The end will generate a certain bending stress, and the smaller the diameter of the main cable, the greater the bending stress. The pin hinged cable clamp is designed with a lug plate at the lower part of the circular clamp body. The lug plate is opened for the pin rod to pass through and is connected to the sling. The other end of the sling is connected to the main beam. The sling has no bending stress, so it is relatively Straddle-type cable clamps are used a lot. The body of the cable clamp is mostly made of two cast steel semi-circular components, which are connected with high-strength bolts during installation. The pin-hinged connection generally adopts the design of upper and lower butt joints, and its high-strength bolts need to transmit the tension of the sling, so the total axial force of the bolts is large. The straddle-type cable clamp adopts the design of left and right butt joints. Since its high-strength bolts do not need to transmit the tension of the sling, the total axial force of the bolts is small, and the bolts are more economical to use. Therefore, for long-span suspension bridges, the straddle-type cable clamp has its advantages over the pin-hinged cable clamp.

When the bridge deck is subjected to vehicle loads, the compressive stress on the top area of the main cable in the cable clip increases, while the compressive stress on the bottom area decreases. Considering the loss of screw pre-tension during service, the compressive stress in the entire section of the main cable is reduced, which will reduce the tightening effect of the cable clamp on the main cable. In extreme cases, it may even cause the bottom area of the main cable to separate from the cable clip, seriously affecting the skid resistance of the straddle-type cable clip.

Detailed ways

In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described The embodiments are only some of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

The semi-riding type suspension bridge cable clamp device of the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments:

Example 1

The connection structure of the half-straddle-type cable clip in this embodiment is relatively simple and easy to manufacture. The schematic side views of the suspension bridge cable clip are shown in Figures 1 and 2, and the main cables are not shown in the figures. The cable clamp is of the Haval type, and the butt joint type of the two parts is the upper and lower butt joints. The two ends of the annular contour of the half-cable clip body 1 and the half-cable clip body 2 are provided with connecting steps, and the tooth blocks on their connecting steps are engaged with each other, and the connecting steps are provided with a plurality of bolt holes corresponding to each other. , high-strength bolts composed of nuts 5 and washers 6 connect the two parts together and clamp them on the main cable. There is a straddle slot 3 for placing a sling 11 on the cable clip. The sling 11 is made of steel wire rope. The lower end of the suspension cable 11 is connected to the bridge deck, the anchor head 13 at the upper end is connected to the connection structure located on the second half-cable clip body 2 , and the suspension cable 11 is half-straddled on the cable clip. For the conventional straddle-type cable clip, the two sides of the cable clip directly bearing the pressure of the high-strength bolt are a piece, and the outer side thereof is a vertical plane. The non-shaded part in the action range of the high-strength bolts in Figures 1 and 2 is equivalent to a part of the vertical plane, and the shaded part is the protruding block more than the side of the conventional cable clamp, which is used to support the sling 11, called For the anchor block 9, there is a straddle groove 3 on it. The connection structure is located on the corresponding anchor block 9, and the half-cable clamp body 2 has a positioning groove 7 above the anchor head 13 of the sling 11, which can directly support and position the anchor head 13, or as shown in FIG. There is also a backing plate 12 above the head 13 . The number of slings 11 on the cable clip can be odd or even, as long as the tension balance on both sides is finally achieved. Along the longitudinal direction of the cable clip, the anchor heads 13 of the slings 11 are located on both sides of the cable clip respectively, as shown in the figure 6. The connection method of the sling 11 on the cable clip is shown in Figure 3. The anchoring block 9 in this embodiment is mainly concentrated in the half cable clip body 2, which is relatively easy to manufacture, but the riding groove 3 splits the pressure of the adjacent high-strength bolts. The action area, so that the pressure of each high-strength bolt only affects its local area, this phenomenon mainly occurs in the half-cable clamp body 1. The longitudinal cross-sectional views of different positions of the circumference of the cable clip are shown in Figures 4 and 5. In order to ensure that the cable clip has sufficient wall thickness, in the top area of the half-cable clip body 1, two convex strips 10 are provided for the riding groove 3 on both sides. , which protrudes from the main body of the half-cable clip body-1.

Example 2

This embodiment is a modification of Embodiment 1, and the schematic side view after the sling is installed is shown in FIG. 7 . In this embodiment, the simplicity of manufacture is not introduced too much, and more attention is paid to the force of the sling 11 , so as to reduce the degree of extrusion between the sling 11 and the side wall of the spanning groove 3 , and reduce the micro-wear of the end of the sling 11 . The section of the straddle slot 3 on the side of the anchor head 13 is located at the higher end of the clip with respect to the cross-section of the clip at the lowest point of the overstraddle slot 3 at the top of the main cable. In this way, after the sling is installed, the segment of the sling 11 in the spanning slot 3 is a three-dimensional curve with a non-circular distribution. At the top of the cable clip, the tangent of the sling 11 segment is continuous, or the transverse curvature is relatively small. Small, it can reduce the lateral compressive stress on the sling 11 at the top of the clip.

Example 3

This embodiment is an improved form of Embodiment 1, and the schematic diagram of the vertical section of the cable clip along the sling curve is shown in FIG. 8 . The disengagement point where the cable clamp and the sling 11 come out of contact is located on the half-cable clamp body-1, specifically on the downwardly protruding tooth block of the connecting step, and the disengagement point is the cross section of the main cable passing through the disengagement point. The center of the circle is of equal height. The D-D line in FIG. 8 is located on the horizontal plane of the center of the cross section of the main cable in the cable clip, and the detachment point of the sling 11 is also located on the D-D line. The purpose of this design is to facilitate the calculation of the length of the sling 11, because the length of the segment below the breakaway point is easy to calculate, and it is only necessary to superimpose the length of the sling 11 on the cable clip during design.

Example 4

This embodiment is an improved form of Embodiment 3, and the schematic diagram of the vertical section of the cable clip along the sling curve is shown in FIG. 9 . In the half-cable clamp body 1, the fixing ear 14 under the sling 11 is thickened, and the protruding piece is called the support block 16, and the spanning groove 3 does not enter the action range of the high-strength bolt pressure corresponding to the conventional cable clamp, that is, The inner side of the vertical dotted line in Fig. 9 no longer splits the action area of the adjacent high-strength bolt pressure, which is beneficial to ensure the flexural rigidity of the cable clip and improve the integrity of the cable clip.

Example 5

This embodiment is a modification of Embodiment 1. Referring to FIG. 16 , in this embodiment, the upper end of the sling 11 is no longer hung on the open hanging lug, but is connected to the plug lug with a pin hole. In this example, the anchor head 13 at the upper end of the sling 11 has an ear plate with a pin hole, the anchor block 9 has two opposite ear plates, and the ear plate also has pin holes. The lugs on the anchor head 13 extend between the two lugs on the anchoring block 9, and the pin rods 17 are used to pass through the three pin holes in sequence, so that the sling 11 is pinned on the cable clamp.

Example 6

This embodiment is a modification of Embodiment 1, see FIG. 17 . In this embodiment, the anchoring block 9 is no longer integrated with the fixing lug 14 , the anchoring block 9 is located on the outer side wall of the second half-cable clip body 2 , and the upper end of the sling 11 is connected to the lug with pin hole. In this example, the anchor head 13 at the upper end of the sling 11 has an ear plate with a pin hole, the anchor block 9 has two opposite ear plates, and the ear plate also has pin holes. The lugs on the anchor head 13 extend between the two lugs on the anchoring block 9, and the pin rods 17 are used to pass through the three pin holes in sequence, so that the sling 11 is pinned on the cable clamp.

Example 7

This embodiment is a modification of Embodiment 5, see FIG. 18 . In order to reduce the bending of the sling 11 , improve the stress state of the end of the sling 11 and prolong the service life, an arc-shaped body 15 is used to connect the end of the sling 11 and the anchoring block 9 . In this example, the anchor head 13 at the upper end of the sling 11 has an ear plate with a pin hole, the anchor block 9 has two opposite ear plates, and the ear plate also has pin holes. The arc-shaped body 15 has lugs at both ends, two opposite lugs on the upper end, an lug in the middle of the lower end, and pin holes on the lugs. The lugs on the anchor head 13 protrude between the two lugs on the upper end of the arc body 15, and the pin rods 17 are used to pass through the three pin holes in sequence; Between the two lugs, use the pin rod 17 to pass through the three pin holes in sequence.

The lower end of the sling 11 is connected to the bridge deck, the sling 11 is half-riding on the cable clip, and the anchor head 13 at the upper end is connected to the anchoring block 9 on the lower side of the main cable. The fixing ears 14 are integrated. The main feature of this embodiment is that the advantages of conventional cable clamps are brought into play, and the cable clamp is under the pulling force of all the slings 11 on it, so that the half-cable clamp body 1 and the half-cable clamp body 2 are tightly squeezed together , which avoids the disadvantage that the conventional cable clip is easy to expand the porosity between the wires at the bottom of the main cable, and the greater the tension of the sling 11, the greater the extrusion stress of the cable clip to the main cable, which can ensure that the cable clip does not slide.

To sum up, the functions of some of the technical features of the present invention are as follows. The straddle groove port on the side of the sling connection to the main beam is provided with a divergent port, which can adapt to the swing range of the sling. The straddle slot is a curved slot for accommodating and positioning the sling. The positioning slot can stabilize the position of the anchor head as much as possible, and the end slot is designed to cooperate with the connection of anti-rust kits, such as wrapping tape. The anchoring block is an extended fixing block, and the upper part of the anchoring block is provided with an opening for inserting or penetrating the sling. The protruding strip protrudes from the surface of the cable clip body, and extends outward to increase the depth of the riding groove without reducing the standard size of the cable clip body.

The idea of the utility model is that the first and second half cable clips are upper and lower cable clips that are connected up and down respectively, and the openings on both sides of the riding groove are respectively located on the side walls of the first half cable clip body. , at the same time on the side wall of the second half-cable clip body or respectively on the side walls of the first half-cable clip body and the second half-cable clip body.

The area where the anchoring block can be set in this structure is to go over the spanning groove at the highest point of the vertical plane, to the lowest point of the cable clamp body, and finally land at the place where the projection angle is 215 degrees on the plane rectangular coordinate system , without touching the straddle starting point of the sling.

Half cable clip body 1 and half cable clip body 2 are left and right cable clips that are butted left and right, respectively, and the openings on both sides of the straddle groove are respectively located on the side walls of half cable clip body 1, and at the same time on the half cable clip body. The two side walls are respectively located on the side wall of the first half-cable clip body and the second side wall of the half-cable clip body at the same time.

The anchoring block in this structure can also be set in an area that crosses from the riding groove at the highest point of the vertical plane, goes all the way to the lowest point of the cable clamp body, and finally falls at a projection angle of 215 degrees on the plane rectangular coordinate system. place, without touching the start of the straddle of the sling.

This winding method is equally applicable even at the operating rotation inclination angle between the plane where the half-cable clip body 1 and the half-cable clip body 2 are spliced and the horizontal plane. , has always crossed the lowest point of the cable clip body, and finally landed at the place where the projection angle is 215 degrees on the plane rectangular coordinate system, without touching the starting point of the sling.

The half-cable clip body 1 and the half-cable clip body 2 are spliced and then sleeved on the main cable of the suspension bridge, and the rotation inclination angle between the plane where the splicing place is located and the horizontal plane is α4, where 0°≤α4≤90°.

This explanation also applies to the case where the first and second half-cable clamps are spliced together, then rotated and then sleeved on the main cable of the suspension bridge.

This solution is also applicable to the situation where the sling is pulled upward. For example, in order to increase the lateral stiffness or vertical stiffness of a long-span bridge or a long-span slender structure, a stabilizing cable will be installed. It protrudes upwards under the action of upward pulling force, and the similar cable clamp device used at this time is also included in this scheme.
