Technical Field

[0001] The present invention relates to the technical field of building construction, and in particular to an auxiliary connection device for the outer protection sleeve of a stay cable and its usage method. Background Art

[0002] A cable-stayed bridge, also known as a cable-stayed bridge, is a bridge in which the main beam is directly pulled on the bridge tower by many stay cables. It is a structural system composed of a pressure-bearing tower, a tensioned cable, and a beam body that bears bending. It can be regarded as a multi-span elastic support continuous beam with stay cables replacing the piers. It can reduce the bending moment in the beam body, lower the building height, and reduce the structural weight.

[0003] During the construction of a cable-stayed bridge, an installation pipe 1 communicating with the cable saddle is provided on the side wall of the tower column. The installation of the stay cable mainly uses a cable threading machine to push, and the stay cables are strung one by one in cooperation with the outer protection sleeve of the stay cable. During the operation and construction, usually a crane is used to lift one end of the outer protection sleeve of the stay cable, so that one end of the outer protection sleeve of the stay cable is close to the installation pipe 1, and then the temporary hoisting connection between the installation pipe 1 and the outer protection sleeve of the stay cable is realized through a connecting strand. The other end of the outer protection sleeve of the stay cable is also temporarily hoisted and connected to the installation pipe 2 located on the bridge deck through a connecting strand, and then the cable stringing operation is carried out in cooperation. Since the hoisting connection between the installation pipe 1 and the outer protection sleeve of the stay cable is realized through a connecting strand, during the cable stringing construction of the stay cable, when the outer protection sleeve of the stay cable is shaken due to wind or other influences, the pipe orifice of the outer protection sleeve of the stay cable will shake and shift relative to the pipe orifice of the installation pipe 1, which will affect the cable stringing operation.

[0035] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following combines the attached drawings and preferred embodiments to elaborate in detail on the specific implementation mode, structure, features and their effects of the present invention as follows.

[0036] Refer to Figures 1-9 , an auxiliary connection device for the outer protective sleeve of a stay cable, including a limiting piece 33 arranged on the outer surface of the first installation pipe 1 and a lifting piece 3 on the outer protective sleeve body 2 of the stay cable. The lifting piece 3 is a prior art. The lifting piece 3 includes two first splicing parts 4. On one side of the upper first splicing part 4, two arc seats 5 are movably arranged. On one side of each arc seat 5, a plurality of insertion rods 6 are fixed. One end of each insertion rod 6 movably penetrates through the first splicing part 4 and the limiting piece 33. A fixing component is arranged on each arc seat 5, and an anti-dropping unit is arranged between each insertion rod 6 and the first splicing part 4.

[0037] The connection mode between the limiting piece 33 and the first installation pipe 1 is detachable, and the connection mode between the lifting piece 3 and the outer protective sleeve body 2 of the stay cable is also detachable.

[0038] In the initial preparation stage, the limiting piece 33 can be installed and sleeved on the outer surface of the corresponding end of the first installation pipe 1. When one end of the outer protective sleeve body 2 of the stay cable is lifted to be close to the end of the first installation pipe 1, adjust the position of the end of the outer protective sleeve body 2 of the stay cable so that the pipe orifice (end) of the outer protective sleeve body 2 of the stay cable is aligned with the pipe orifice (end) of the first installation pipe 1. Then, push the arc seat 5 towards the direction of the first installation pipe 1. The arc seat 5 drives the insertion rod 6 to move towards the direction of the first installation pipe 1 until one end of the insertion rod 6 movably penetrates through the first splicing part 4 and the limiting piece 33. Then, limit and fix the arc seat 5 through the set fixing component. Then, use the prior art to realize the lifting connection between the first installation pipe 1 and the outer protective sleeve body 2 of the stay cable. At this time, the pipe orifice of the outer protective sleeve body 2 of the stay cable is always facing the pipe orifice of the first installation pipe 1, so as to achieve the effect of positioning and strengthening one end of the outer protective sleeve body 2 of the stay cable.

[0039] The limiting member 33 includes two second splicing parts 7. Each second splicing part 7 includes two second semi-circular rings 8. A second reinforcing plate 9, a second locking plate 10 and a second rotating plate 11 are fixed between the two second semi-circular rings 8. A locking unit is arranged between the two second locking plates 10. A rotating shaft 12 is rotatably arranged between the two second rotating plates 11. One end of each insertion rod 6 movably penetrates through the corresponding two second semi-circular rings 8, and a slot for cooperating with the insertion rod 6 is formed on the side wall of the second semi-circular ring 8.

[0040] During use, the two second splicing parts 7 used in cooperation are flipped open by a certain angle through the provided rotating shaft 12, then sleeved on the outer surface of the first installation pipe 1, and then the two second splicing parts 7 are locked and closed through the locking unit, so that the two second splicing parts 7 used in cooperation are fixedly sleeved on the outer surface of the first installation pipe 1.

[0041] The locking unit includes notches 13 formed on the side walls of the two second locking plates 10. A threaded column 14 is rotatably arranged in the notch 13 located below. Two connecting columns 15 are symmetrically fixed on the outer surface of the lower section of the threaded column 14. Each connecting column 15 rotatably penetrates into the corresponding second locking plate 10, and a locking nut 16 is threadedly connected to the outer surface of the upper section of the threaded column 14.

[0042] When the two second splicing parts 7 are sleeved on the outer surface of the first installation pipe 1, at this time, the two second locking plates 10 are butted together. Then the threaded column 14 is rotated upward to drive the corresponding locking nut 16 to rotate together until the locking nut 16 is located above the second locking plate 10. Then the locking nut 16 is tightened to make the two second locking plates 10 firmly contact each other, so that the two second splicing parts 7 used in cooperation are fixedly sleeved on the outer surface of the first installation pipe 1.

[0043] Each first splicing part 4 includes two first semi-circular rings 17. Two first connecting plates 18 are fixed between the two first semi-circular rings 17. A middle semi-circular ring 19 is fixed between the two first connecting plates 18. A first reinforcing plate 20 is also fixed between the two first semi-circular rings 17. A plurality of lifting rings 21 are rotatably arranged on the side wall of the first reinforcing plate 20 located above.

[0044] During use, the two first splicing parts 4 are butted and clamped on the outer surface of the outer protection sleeve body 2 of the stay cable. Through the provided lifting rings 21, the hoisting operation of the crane is realized in cooperation, etc.

[0045] A plurality of installation bolts 22 penetrate through between adjacent two first connecting plates 18. An installation nut 23 is threadedly connected to the upper end of each installation bolt 22.

[0046] Before the hoisting operation of the outer protective sleeve body 2 of the stay cable is realized, first, the two splicing parts I 4 are butted and held together on the outer surface of the outer protective sleeve body 2 of the stay cable. At this time, the adjacent two connecting plates I 18 are butted together, and then through the set installation bolts 22 and installation nuts 23, the limit fixation of the adjacent two connecting plates I 18 is realized, so as to fixedly sleeve the two splicing parts I 4 on the outer surface of the outer protective sleeve body 2 of the stay cable.

[0047] One end of the outer protective sleeve body 2 of the stay cable far from the installation pipe I 1 can be fixedly sleeved with an installation sleeve or the like, which is used to realize the hoisting connection between the end of the outer protective sleeve body 2 of the stay cable and the end of the installation pipe II located on the bridge deck. The specific operation method is a conventional technical means in this field.

[0048] Each fixing component includes a lifting plate 24. Each lifting plate 24 is movably arranged above the corresponding arc seat 5. The lower end surface of the lifting plate 24 is fixed with a mounting plate 25. The lower end surface of the mounting plate 25 is provided with a mounting groove, and a contact wheel 26 is rotatably arranged in the mounting groove. A guiding unit and a driving unit for cooperating with the lifting plate 24 are arranged on the arc seat 5.

[0049] In the initial state, the contact wheel 26 is in a position far from the surface of the outer protective sleeve body 2 of the stay cable, so as to avoid the contact wheel 26 affecting the displacement of the arc seat 5 when the arc seat 5 approaches the corresponding semi - ring I 17.

[0050] When one end of the insertion rod 6 movably penetrates through the splicing part II 7, at this time, the arc seat 5 moves and abuts against the side wall of the semi - ring I 17. Then, through the set driving unit cooperating with the guiding unit, the lifting plate 24 is urged to drive the mounting plate 25 and the contact wheel 26 to move downward. During the process of the contact wheel 26 moving towards the surface of the outer protective sleeve body 2 of the stay cable, it always abuts and fits against the side wall of the semi - ring I 17. When the contact wheel 26 moves to the specified position and stops moving, at this time, the contact wheel 26 and the arc seat 5 clamp and abut against both sides of the corresponding semi - ring I 17, realizing the limit fixation of the arc seat 5, and thus realizing the limit fixation of the insertion rod 6.

[0051] According to needs, the end of the insertion rod 6 can also be set to be threaded. Then, when the end of the insertion rod 6 penetrates through the splicing part II 7, a limit nut is installed at the end of the insertion rod 6 until the limit nut abuts against the outer side wall of the semi - ring II 8, further realizing the limit fixation of the insertion rod 6 and the arc seat 5.

[0052] Each guiding unit includes a lifting groove opened on the upper surface of the arc seat 5. A lifting block 27 is movably arranged in the lifting groove, and the upper end surface of the lifting block 27 is fixedly connected with the lower end surface of the lifting plate 24.

[0053] Through the set lifting groove and lifting block 27, the lifting movement of the lifting plate 24, the mounting plate 25 and the contact wheel 26 is limited and guided.

[0054] Each driving unit includes an L-shaped plate 28 fixed to one side of the arc-shaped seat 5. Between the inner top of the L-shaped plate 28 and the bottom of the lifting groove, two guiding columns 29 are symmetrically fixed. Each guiding column 29 movably penetrates through the lifting block 27. Between the inner top of the L-shaped plate 28 and the bottom of the lifting groove, a threaded rod 30 is rotatably arranged. The threaded rod 30 threadedly penetrates through the lifting block 27 and the lifting plate 24. The upper end of the threaded rod 30 rotatably penetrates through the L-shaped plate 28 and is fixed with a handwheel 31.

[0055] When the arc-shaped seat 5 moves and abuts against the side wall of the first semi-circular ring 17, rotate the handwheel 31 to drive the threaded rod 30 to rotate, thereby driving the lifting block 27 to move, and then driving the lifting plate 24, the mounting plate 25 and the abutting wheel 26 to move towards the direction close to the outer sheathing body 2 of the stay cable.

[0056] Each anti-detachment unit includes an anti-detachment sleeve 32. Each anti-detachment sleeve 32 is fixedly sleeved on the outer surface of the corresponding insertion rod 6. A through groove for cooperating with the anti-detachment sleeve 32 is formed on the side wall of the middle semi-circular ring 19.

[0057] By providing the anti-detachment sleeve 32, it is ensured that the anti-detachment sleeve 32 can only move between the corresponding two first semi-circular rings 17, restricting the moving stroke of the insertion rod 6, and avoiding the insertion rod 6 and the arc-shaped seat 5 falling off the lifting member 3 when hoisting and moving the outer sheathing body 2 of the stay cable.

[0058] A usage method of an auxiliary connection device for an outer sheathing of a stay cable, and the specific operation steps of this method are as follows:

[0059] Step 1, install and sleeve the limiting member 33 on the outer surface of the end of the corresponding first mounting pipe 1;

[0060] Step 2, hoist one end of the outer sheathing body 2 of the stay cable to be close to the end of the first mounting pipe 1, adjust the position of the end of the outer sheathing body 2 of the stay cable so that the pipe orifice of the outer sheathing body 2 of the stay cable is aligned with the pipe orifice of the first mounting pipe 1;

[0061] Step 3, push the arc-shaped seat 5 towards the direction of the first mounting pipe 1. The arc-shaped seat 5 drives the insertion rod 6 to move towards the direction of the first mounting pipe 1 until one end of the insertion rod 6 movably penetrates through the first splicing part 4 and the limiting member 33. Then, limit and fix the arc-shaped seat 5 through the provided fixing assembly, and then use the existing technology to realize the hoisting connection between the first mounting pipe 1 and the outer sheathing body 2 of the stay cable.

[0062] When the present invention is in use, in the initial preparation stage, the limiting member 33 can be installed and sleeved on the outer surface of the corresponding end of the first installation pipe 1. After one end of the outer protective sleeve body 2 of the stay cable is hoisted close to the end of the first installation pipe 1, the position of the end of the outer protective sleeve body 2 of the stay cable is adjusted to align the pipe orifice (end) of the outer protective sleeve body 2 of the stay cable with the pipe orifice (end) of the first installation pipe 1. Then, the arc-shaped seat 5 is pushed towards the direction of the first installation pipe 1, and the arc-shaped seat 5 drives the insertion rod 6 to move towards the direction of the first installation pipe 1 until one end of the insertion rod 6 movably penetrates through the first splicing part 4 and the limiting member 33. Then, the arc-shaped seat 5 is limited and fixed by the provided fixing assembly. Then, the prior art is adopted to realize the hoisting connection between the first installation pipe 1 and the outer protective sleeve body 2 of the stay cable. At this time, the pipe orifice of the outer protective sleeve body 2 of the stay cable is always facing the pipe orifice of the first installation pipe 1, so as to achieve the effect of positioning and strengthening one end of the outer protective sleeve body 2 of the stay cable;

[0063] When one end of the insertion rod 6 movably penetrates through the second splicing part 7, at this time, the arc-shaped seat 5 moves and abuts against the side wall of the first semi-circular ring 17. Then, through the cooperation of the provided driving unit and the guiding unit, the lifting plate 24 drives the mounting plate 25 and the abutting wheel 26 to move downward. During the process of the abutting wheel 26 moving towards the surface of the outer protective sleeve body 2 of the stay cable, it always abuts against and fits the side wall of the first semi-circular ring 17. When the abutting wheel 26 moves to the designated position and stops moving, at this time, the abutting wheel 26 and the arc-shaped seat 5 clamp and abut against both sides of the corresponding first semi-circular ring 17, realizing the limiting and fixing of the arc-shaped seat 5, and thus realizing the limiting and fixing of the insertion rod 6;

[0064] After the arc-shaped seat 5 moves and abuts against the side wall of the first semi-circular ring 17, the hand wheel 31 is rotated to drive the threaded rod 30 to rotate, thereby driving the lifting block 27 to move, and then driving the lifting plate 24, the mounting plate 25 and the abutting wheel 26 to move towards the direction close to the outer protective sleeve body 2 of the stay cable.
