Description

Technical Field

[0001] The invention belongs to the technical field of the construction of spatial cable - shaped suspension bridges, and relates to the system conversion of spatial cable - shaped suspension bridges. Specifically, it relates to a main cable transverse movement system and a construction method for spatial cable - shaped suspension bridges. Background Art

[0002] Different from traditional planar cable - shaped suspension bridges, the surface formed by the main cable and the suspenders of a spatial cable - shaped suspension bridge is a spatial curved surface. The plane formed by the main cable and the suspenders is no longer a vertical plane but a laterally inclined plane, that is, the main cable has not only a vertical sag but also a lateral sag. This results in a large difference in the lateral coordinates of the spatial cable - shaped suspension bridge between the empty - cable stage and the completed - bridge stage. Therefore, before installing the suspender clip, it is necessary to control the alignment of the spatial main cable to ensure that the suspender ear plate can be smoothly inserted into the clip ear plate, and there will be no large bending at the contact between the two.

[0003] The existing methods for converting the alignment of the main cable of spatial cable - shaped suspension bridges mainly include the "temporary cable method" and the "temporary cross - brace method". Among them, the "temporary cable method" uses temporary suspenders to open the empty - cable laterally outward, so that the empty - cable alignment approaches the completed - bridge alignment in the transverse direction of the bridge; the "temporary cross - brace method" installs a temporary cross - brace above the main cable and uses a winch for tensioning to push the main cable outward, so that the empty - cable alignment approaches the completed - bridge alignment in the transverse direction of the bridge.

[0004] The above - mentioned existing technologies mainly have the following defects:

[0005] First, both of the above - mentioned methods drive the main cable to move transversely by pulling the position of the main cable clamp through cables. It is very difficult to control the displacement of the main cable moved by cable traction, resulting in difficulty in accurately positioning the main cable and affecting the alignment of the spatial main cable.

[0006] Second, both of the above - mentioned methods have strong constraints on the main cable during the system conversion process. This will cause the main cable to undergo constrained torsion during the transverse movement, and there are often phenomena such as strand bulging and strand entanglement. The phenomena of strand bulging and strand entanglement will cause some strands to fail and lose part of their bearing capacity, posing a great potential safety hazard. Summary of the Invention

[0007] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a main cable transverse movement system and a construction method for spatial cable - shaped suspension bridges, so as to solve the technical problem that in the system conversion of spatial cable - shaped suspension bridges in the prior art, it is difficult to control the displacement of the main cable movement, which in turn makes it difficult to accurately position the main cable and affects the alignment of the spatial main cable.

[0008] To solve the above - mentioned technical problems, the present invention is implemented by adopting the following technical solutions:

[0009] A main cable transverse movement system for a spatial cable - shaped suspension bridge, comprising a traction device guide rail arranged along the transverse direction, and a right traction device sleeved on the traction device guide rail.

[0010] The right traction device includes a dynamic reaction frame and a dynamic traction frame sleeved on the traction device guide rail. The dynamic reaction frame is located on the transverse inner side of the dynamic traction frame. The outer end of a threaded steel rod in the transverse direction is fixedly installed at the bottom end of the dynamic traction frame. The inner end of the threaded steel rod in the transverse direction passes through the dynamic reaction frame and is fixedly connected to the top of an adaptive rotating main cable clamp. A spatial main cable is arranged inside the adaptive rotating main cable clamp along the longitudinal direction.

[0011] A plurality of guiding elastic automatic locks are fixedly arranged on both longitudinal sides of the traction device guide rail. The guiding elastic automatic lock includes a guiding lock fixing block fixedly installed on the traction device guide rail. A guiding lock movable block is rotatably installed on the transverse outer side of the guiding lock fixing block. The inner end of a guiding lock spring in the longitudinal direction is fixedly installed on the transverse inner side of the guiding lock fixing block. The outer end of the guiding lock spring in the longitudinal direction is fixedly connected to the guiding lock movable block.

[0012] One reaction elastic automatic lock is respectively fixedly arranged on both longitudinal inner sides of the dynamic reaction frame, and a pair of reaction elastic automatic locks are arranged oppositely. The reaction elastic automatic lock includes a reaction lock movable block. The length direction of the reaction lock movable block is arranged vertically, and the reaction lock movable block can be flipped towards the transverse inner side. When the transverse inner side of the reaction lock movable block tightly abuts against the transverse outer side of the guiding lock movable block, the dynamic reaction frame does not move in the transverse direction at this time, and the dynamic traction frame can move towards the transverse outer side on the traction device guide rail, thereby driving the adaptive rotating main cable clamp and the spatial main cable to move towards the transverse outer side.

[0089] A pair of upper spring connecting rod outer card slots 20205 are arranged on the transverse inner side of the upper beam 20201 of the traction frame; a pair of traction frame rollers 20206 are rotatably installed on the bottom surface of the upper beam 20201 of the traction frame, and the traction frame rollers 20206 are in contact with the top surface of the traction device guide rail 1.

[0090] A pair of lower spring connecting rod outer card slots 20207 are arranged on the transverse inner side of the lower beam 20202 of the traction frame, and a lower spring connecting rod 206 is fixedly clamped in the lower spring connecting rod outer card slots 20207; a pair of deformed steel bar pull rod fixing holes 20208 are formed in the lower beam 20202 of the traction frame, and a deformed steel bar pull rod 4 is fixedly installed in the deformed steel bar pull rod fixing holes 20208.

[0092] In this embodiment, the traction frame rollers 20206 and the reaction frame rollers 20107 can reduce the friction force between the dynamic reaction frame 201 and the dynamic traction frame 202 and the traction device guide rail 1, so that the dynamic reaction frame 201 and the dynamic traction frame 202 can move better.

[0093] As a specific solution of this embodiment, as Figure 7 and Figure 8 shown, the adaptive rotation main cable clamp 5 includes an upper half outer clamp 501 and a lower half outer clamp 502, and the upper half outer clamp 501 and the lower half outer clamp 502 are fixedly connected to form a complete outer clamp; an upper half inner clamp 503 is arranged inside the upper half outer clamp 501, a lower half inner clamp 504 is arranged inside the lower half outer clamp 502, and the upper half inner clamp 503 and the lower half inner clamp 504 are fixedly connected to form a complete inner clamp, and a spatial main cable 6 is fixedly arranged inside the inner clamp.

[0096] In this embodiment, there is no relative sliding or rotation between the inner clamping clip and the spatial main cable 6, and the outer clamping clip can rotate self-adaptively along the circumferential direction of the spatial main cable 6. This self-adaptive rotating main cable clamping clip 5 can effectively avoid the strand torsion phenomenon when the spatial main cable 6 transverses.

[0097] In this embodiment, a polytetrafluoroethylene plate 510 is provided at the top of the upper half outer clamping clip 501. The polytetrafluoroethylene plate 510 is used to reduce the friction between the self-adaptive rotating main cable clamping clip 5 and the guiding rail 1 of the traction device.

[0101] Embodiment 2:

[0102] This embodiment provides a construction method, which adopts the main cable transverse movement system of the spatial cable-shaped suspension bridge in Embodiment 1. This method specifically includes the following steps:

[0103] Step 1, install the self-adaptive rotating main cable clamping clip:

[0104] Design the self-adaptive rotating main cable clamping clip 5 according to the diameter of the spatial main cable 6. After determining the position of the self-adaptive rotating main cable clamping clip 5, first sleeved the upper half inner clamping clip 503 and the lower half inner clamping clip 504 outside the spatial main cable 6, and then fixedly connect the upper half inner clamping clip 503 and the lower half inner clamping clip 504 with high-strength bolts 11, so that the inner clamping clip is fixed on the spatial main cable 6.

[0105] After the fixed installation of the inner clamping clip is completed, the upper rolling frame 507 and the lower rolling frame 508 with rolling columns 509 are sleeved outside the inner clamping clip, and the upper rolling frame 507 and the lower rolling frame 508 are fixedly connected.

[0106] After the installation of the rolling frame is completed, the upper half outer clamping clip 501 and the lower half outer clamping clip 502 are sleeved outside the rolling frame, and the upper half outer clamping clip 501 and the lower half outer clamping clip 502 are fixedly connected with high-strength bolts 11, thus completing the installation of the self-adaptive rotating main cable clamping clip.

[0107] Step two, install the right traction device and the left traction device:

[0108] After the installation of the self-adaptive rotating main cable clamping clip in step one is completed, the dynamic reaction frame 201 and the dynamic traction frame 202 of the right traction device 2 are pushed onto the right traction device guide rail 101, and the dynamic reaction frame 201 and the dynamic traction frame 202 of the left traction device 3 are pushed onto the left traction device guide rail 102.

[0109] After the dynamic reaction frame 201 and the dynamic traction frame 202 are pushed to the preset positions, the spring connecting plates 20501 of the upper spring connecting rod 205 and the lower spring connecting rod 206 are respectively clamped in the inner clamping grooves 20105 of the upper spring connecting rod, the inner clamping grooves 20108 of the lower spring connecting rod, the outer clamping grooves 20205 of the upper spring connecting rod, and the outer clamping grooves 20207 of the lower spring connecting rod, and then the upper spring connecting rod 205 and the lower spring connecting rod 206 are fixed on the dynamic reaction frame 201 and the dynamic traction frame 202 with high-strength bolts 11.

[0110] After the installation of the upper spring connecting rod 205 and the lower spring connecting rod 206 is completed, the right traction device guide rail 101 and the left traction device guide rail 102 are fixedly connected with high-strength bolts 11.

[0111] Step three, connect the dynamic traction frame and the self-adaptive rotating main cable clamping clip, and place the jack.

[0112] The traction device guide rail 1 installed with the right traction device 2 and the left traction device 3 in step two is hoisted and the position is adjusted so that the connecting end faces of the right traction device 2 and the left traction device 3 coincide with the vertical plane where the bridge center line is located. Then, the traction device guide rail 1 is slowly hoisted above the spatial main cable 6 installed with the self-adaptive rotating main cable clamping clip 5 in step one so that the guiding support bottom plate 10102 contacts the top of the upper half outer clamping clip 501; then, the threaded steel rod 4 is passed through the threaded steel rod fixing hole 20208 and the threaded steel rod installation hole 506, and the threaded steel rod 4 is fixed on the dynamic traction frame 202 and the self-adaptive rotating main cable clamping clip 5 with high-strength nuts 12, thus completing the connection between the dynamic traction frame and the self-adaptive rotating main cable clamping clip.

[0113] After completing the connection of the dynamic traction frame and the adaptive rotating main cable grip, place the upper jack 203 and the lower jack 204 on the upper jack placement platform 20106 and the lower jack placement platform 20109 respectively, and adjust the positions of the upper jack 203 and the lower jack 204 so that the lateral ends of the upper jack 203 and the lower jack 204 are closely attached to the dynamic reaction frame 201 and the dynamic traction frame 202.

[0114] Step Four, main cable transverse movement construction.

[0115] After ensuring that the lateral outer side of the reaction lock fixing block 802 abuts against the lateral inner side of the guide lock movable block 701, start the upper jack 203 and the lower jack 204 to push the dynamic traction frame 202, and the dynamic traction frame 202 drives the spatial main cable 6 to move along the transverse direction until the spatial main cable 6 moves to the preset position.

[0116] Then, after removing the jacking force applied by the upper jack 203 and the lower jack 204, when the lateral inner side of the traction lock movable block 901 tightly abuts against the lateral outer side of the guide lock movable block 701, the dynamic reaction frame 201 moves towards the lateral outer side direction until the dynamic reaction frame 201 stops moving, and one-step small displacement jacking process is completed.

[0117] Repeat the above process. After multiple steps of small displacement jacking, until the spatial main cable 6 is transversely moved to the established alignment position, the main cable transverse movement construction is completed.

[0118] In this embodiment, as Figure 10 shown, taking the right traction device 2 as an example, at the start of the main cable transverse movement construction, the positional relationship among the guide lock movable block 701, the reaction lock fixing block 802, and the traction lock movable block 901 is as shown in A in Figure 10 ; as shown in B in Figure 10 , as the dynamic traction frame 202 moves, when the lateral outer side of the traction lock movable block 901 comes into contact with the lateral inner side of the guide lock movable block 701; as shown in C in Figure 10 , the traction lock movable block 901 and the guide lock movable block 701 will flip; then the dynamic traction frame 202 continues to move until the spatial main cable 6 moves to the preset position.

[0119] After removing the jacking force applied by the upper jack 203 and the lower jack 204, as shown in D in Figure 10 , when the lateral inner side of the traction lock movable block 901 tightly abuts against the lateral outer side of the guide lock movable block 701, at this time, the dynamic traction frame 202 does not move in the transverse direction; as shown in Figure 10As shown by E in [reference], the dynamic reaction frame 201 will move towards the lateral outer direction until the upper spring connecting rod 205 and the lower spring connecting rod 206 stop contracting and the dynamic reaction frame 201 stops moving. At this time, the positional relationship among the guide lock movable block 701, the reaction lock fixed block 802, and the traction lock movable block 901 is as shown by Figure 10 F in [reference].

[0120] Step 5: Demolish the real-time transverse movement system for the adaptive rotation of the spatial main cable.

[0121] After the suspension bridge system conversion is completed, first remove the threaded steel tie rod 4, then remove the upper spring connecting rod 205, the lower spring connecting rod 206, the upper jack 203, and the lower jack 204, and then push the dynamic reaction frame 201 and the dynamic traction frame 202 off the right traction device guide rail 101 and the left traction device guide rail 102. After the removal of the right traction device 2 and the left traction device 3 is completed, then remove the adaptive rotation main cable clamp 5 from the spatial main cable 6.
