Description

Technical Field

[0001] The present invention belongs to the technical field related to bridge construction, and more specifically, it is a wire dividing tube saddle guiding and positioning device for a cable-stayed bridge and its working method. Background Art

[0002] A wire dividing tube saddle guiding and positioning device for a cable-stayed bridge is a device used in the installation process of a cable-stayed bridge saddle to assist in positioning the wire dividing tube and the main pipe body. A saddle refers to a supporting structure for a suspension cable or a stay cable to pass through the top of a tower. The upper seat of the saddle is usually made of a ribbed arc-shaped cast steel block, and is provided with a cable groove for placing the suspension cable or the stay cable. For the saddle in a rigid bridge tower, generally, a row of roller shafts is also provided under the upper seat, and a lower seat bottom plate is provided under the roller shafts to better distribute the concentrated load transmitted by the roller shafts on the tower column.

[0003] The application document with the publication number CN116607411A records a saddle and a manufacturing method of the saddle, belonging to the technical field of bridge cable clamps. The saddle includes a saddle head, a base, and a plurality of transverse ribs. The saddle head includes a saddle head body and at least one saddle head longitudinal rib, and the at least one saddle head longitudinal rib is connected to the bottom of the saddle head body; the base includes a base body and at least one base longitudinal rib, and the base longitudinal rib is connected to the top of the base body. The at least one base longitudinal rib corresponds to and contacts the at least one saddle head longitudinal rib one by one; the transverse ribs are arranged in pairs, and the paired transverse ribs are respectively located on opposite sides of the saddle head or opposite sides of the base, and the base and the saddle head are connected together through the transverse ribs.

[0004] The above saddle structure has certain deficiencies in installation and use. The traditional saddle uses welding to fix the wire dividing tube, and it is necessary to control the length, bending radius, and structural style of the wire dividing tube. When the wire dividing tube is installed, the wire dividing tubes with different bending radii are prone to dislocation, resulting in confusion during on-site installation, making it impossible for the overall assembly of the wire dividing tube to maintain the same bending radius and length, affecting the subsequent steel cable installation effect, and at the same time, it cannot be flexibly applied to the installation operations of different numbers of wire dividing tubes, reducing its flexibility in installation and use. Summary of the Invention

[0005] The purpose of the present invention is to provide a wire dividing tube saddle guiding and positioning device for a cable-stayed bridge and its working method, which can solve the existing problems.

[0006] The problems solved by the present invention are:

[0007] 1. Traditional cable saddles fix the wire dividing pipes by welding, which requires controlling the length, bending radius, and structural style of the wire dividing pipes. During the installation operation of the wire dividing pipes, wire dividing pipes with different bending radii are prone to dislocation, resulting in confusion during on-site installation. After the overall assembly of the wire dividing pipes, they cannot maintain the same bending radius and length, affecting the subsequent installation effect of the steel cables. At the same time, it cannot be flexibly applied to the installation operations of different numbers of wire dividing pipes, reducing the flexibility during its installation and use.

[0008] The object of the present invention can be achieved through the following technical solutions:

[0009] A guiding and positioning device for a wire dividing pipe cable saddle of a cable-stayed bridge, comprising an outer pipe body, a positioning frame, and several groups of wire dividing pipes. The outer pipe body is located inside the positioning frame. The positioning frame is made by welding a steel frame structure, and both ends of the outer pipe body and the positioning frame are fixedly welded through channel steel. Several groups of wire dividing pipes are all sleeved inside the outer pipe body. The overall of the outer pipe body and several groups of wire dividing pipes are all arc-shaped. Five guiding rings are sleeved between the outer pipe body and several groups of wire dividing pipes. The five guiding rings are distributed in an arc shape and are arranged at equal intervals. A pipe-passing disk for docking the wire dividing pipes is spliced and installed inside the guiding rings. Several pipe-passing grooves are arranged on the outer surface of the pipe-passing disk. The pipe-passing disk and the wire dividing pipes are mutually docked through the pipe-passing grooves.

[0010] As a further technical solution of the present invention, several rollers are arranged on the outer surface of the guiding ring. The several rollers are annularly and equally spaced. A limiting sliding groove for cooperating with the several rollers is arranged on the inner side of the outer pipe body. A circular notch is arranged on the outer surface of the guiding ring. By using the settings of the guiding ring and the pipe-passing disk, the wire dividing pipes can be installed on the inner side of the outer pipe body with the same radian, playing an auxiliary positioning role in the installation of the wire dividing pipes inside the outer pipe body. The setting of the rollers can reduce the friction between the guiding ring and the outer pipe body when the guiding ring is installed, enabling the rollers to move along the limiting sliding groove of the outer pipe body.

[0011] As a further technical solution of the present invention, a first anchor plate is fixedly installed on the outer surface of one end of the outer pipe body, and a second anchor plate is fixedly installed on the outer surface of the other end of the outer pipe body. Both the first anchor plate and the second anchor plate are butt-joint fixed through fixing bolts and bolt grooves. Several reinforcing ribs are arranged on the surfaces of the first anchor plate and the second anchor plate. The first anchor plate and the second anchor plate can play a butt-joint fixing role between the outer pipe body and the main pipe body through the fixing bolts.

[0012] As a further technical solution of the present invention, reinforcing ribs are installed between the first anchor plate and the outer pipe body and between the second anchor plate and the outer pipe body. One end of the reinforcing rib and the outer pipe body are butt-joint fixed through a fixed hanging ear. The stability of the first anchor plate and the second anchor plate can be improved by using the setting of the reinforcing ribs.

[0013] As a further technical solution of the present invention, an upper chuck is movably installed in the middle of the upper end of the pipe-passing disc, a lower chuck is movably installed in the middle of the lower end of the pipe-passing disc, and a docking groove for cooperating with the upper chuck and the lower chuck is provided inside the guiding ring. By fixing the docking groove with the upper chuck and the lower chuck, the pipe-passing disc can be spliced and installed inside the guiding ring, enabling the user to install a pipe-passing disc with a corresponding number of pipe-passing grooves according to the number of wire-dividing pipes.

[0014] As a further technical solution of the present invention, both between the lower chuck and the pipe-passing disc and between the upper chuck and the pipe-passing disc are elastically connected by a first spring. A positioning card slot for cooperating with the first spring is provided inside the pipe-passing disc. The first spring can elastically eject the lower chuck and the upper chuck to prevent the lower chuck and the upper chuck from resetting during docking and fixing.

[0015] As a further technical solution of the present invention, the rollers on the five groups of guiding rings are arranged in a staggered manner, and the total number of rollers on several groups of guiding rings is equal to the number of limit sliding grooves. To ensure that the guiding rings can be fixed at the designated positions on the outer pipe body during installation, by using the setting of several groups of limit sliding grooves in cooperation with the rollers, when the guiding rings are sequentially inserted into the outer pipe body, the docking blocks can be inserted into the designated positioning card slots, so that the five groups of guiding rings are all installed at the designated positions.

[0016] As a further technical solution of the present invention, positioning card slots are provided in the limit sliding grooves of the outer pipe body, and the five groups of positioning card slots are arranged in an equidistant stepped staggered manner. Because the distances of the positioning card slots are the same, when the guiding rings are installed, their docking blocks can be inserted into the corresponding positions to keep the guiding rings installed at equal distances. And because the five groups of guiding rings are sequentially inserted into the interior of the outer pipe body, by using the staggered positioning card slots, the five groups of positioning card slots are installed on five different limit sliding grooves. After the docking block of the first group of guiding rings completes the docking operation, the docking blocks of the remaining guiding rings all complete the docking operation. If the five groups of positioning card slots are installed at equal distances in the limit sliding grooves, when the frontmost guiding ring enters, the docking operation is completed first, and the remaining guiding rings cannot enter the interior of the outer pipe body.

[0017] As a further technical solution of the present invention, a docking block is provided at the lower end of the roller, and the docking block and the guiding ring are elastically connected by a second spring. With the setting of the second spring, when the roller moves to the positioning card slot, the docking block can be ejected outwards, so that the docking block cooperates with the inclined surface chuck to be inserted into the positioning card slot.

[0018] A working method of a cable saddle guiding and positioning device for a cable-stayed bridge wire-dividing pipe includes the following operating steps:

[0019] Step 1: Install the pipe threading disc with corresponding number of pipe threading grooves on the inner side of the guiding ring according to the number of wire dividing pipes, fix the wire dividing pipes by welding method, and successively sleeve five groups of pipe threading discs on the surface of the wire dividing pipes, so that the five groups of pipe threading discs are arranged at equal intervals;

[0020] Step 2: Insert the wire dividing pipe into the inner part of the outer pipe body, so that the rollers of the guiding ring move along the limit sliding groove of the outer pipe body, and fix the guiding ring by using the docking blocks.

[0021] Beneficial effects of the present invention:

[0022] 1. By setting the outer pipe body and the guiding ring, when installing the wire dividing pipes of the cable-stayed bridge, several groups of wire dividing pipes can be uniformly installed inside the outer pipe body, and the installation position and bending radius of the wire dividing pipes can be accurately controlled by using the guiding ring, so that several groups of wire dividing pipes are accurately combined;

[0023] During the operation, by using the guiding ring and the pipe threading disc, the wire dividing pipes can be installed on the inner side of the outer pipe body with the same radian, which plays an auxiliary positioning role in the installation of the wire dividing pipes inside the outer pipe body. The setting of the rollers can reduce the friction between the guiding ring and the outer pipe body when the guiding ring is installed, so that the rollers move along the limit sliding groove of the outer pipe body. Install the pipe threading disc with corresponding number of pipe threading grooves on the inner side of the guiding ring according to the number of wire dividing pipes, successively sleeve five groups of pipe threading discs on the surface of the wire dividing pipes, so that the five groups of pipe threading discs are arranged at equal intervals, and then insert the wire dividing pipe into the inner part of the outer pipe body, so that the rollers of the guiding ring move along the limit sliding groove of the outer pipe body, fix the guiding ring by using the docking blocks, grout into the outer pipe body to fix between the outer pipe body and the wire dividing pipe, so that the outer pipe body and the wire dividing pipe are integrated. The outer pipe body can play a certain protective role for the wire dividing pipe to avoid the wire dividing pipe from rusting. At the same time, by using several groups of pipe threading grooves in the pipe threading disc, it can play a positioning role in the installation between several groups of wire dividing pipes. The setting of the guiding ring can make the combined wire dividing pipes located in the middle position of the outer pipe body, and at the same time make the wire dividing pipes and the outer pipe body maintain the same bending radius, accurately control the installation position of the wire dividing pipes, and avoid confusion between several groups of wire dividing pipes during installation.

[0024] 2. By setting the pipe threading disc, when using the cable saddle guiding and positioning device of the wire dividing pipe of the cable-stayed bridge, the use of the guiding ring is optimized, and the inner side of the guiding ring has a splicing fixed structure, which can flexibly install any number of wire dividing pipes for use, improving its flexibility during use;

[0025] In use, the upper chuck and the lower chuck are used to fix the docking groove, and the pipe-passing disc can be spliced and installed inside the guiding ring, enabling the user to install a pipe-passing disc with a corresponding number of pipe-passing grooves according to the number of wire-dividing pipes. The user sleeved the pipe-passing disc in the middle position of the guiding ring, and the first spring can elastically eject the lower chuck and the upper chuck, so that the lower chuck and the upper chuck are respectively inserted into the docking grooves above and below the guiding ring, avoiding the reset phenomenon when the lower chuck and the upper chuck are docked and fixed, enabling the use of a pipe-passing disc with any number of pipe-passing grooves. At the same time, by using several groups of circular notches arranged on the surface of the guiding ring, when grouting is carried out inside the outer pipe body, the grout can flow evenly into the inside of the outer pipe body.

[0026] 3. By setting the docking block and the positioning slot, when the wire-dividing pipe saddle guiding and positioning device of the cable-stayed bridge is in use, the use effects of the outer pipe body and the guiding ring are improved, the installation positions of the guiding ring and the wire-dividing pipe inside the outer pipe body are accurately controlled, and the installation accuracy of the whole pipe cable structure is improved;

[0027] During operation, to ensure that the guiding ring can be fixed at a specified position on the outer pipe body during installation, by using the setting of several groups of limiting chutes and rollers, when the guiding ring is sequentially inserted into the outer pipe body, the docking block can be inserted into the specified positioning slot, so that all five guiding rings are installed at the specified positions. Because the distances of the positioning slots are the same, when the guiding ring is installed, its docking block can be inserted into the corresponding position, keeping the guiding rings installed at equal distances. And because the five guiding rings are sequentially inserted into the inside of the outer pipe body, by using the positioning slots arranged in a staggered manner, the five positioning slots are installed on five different limiting chutes, so that after the docking block of the first guiding ring completes the docking operation, the docking blocks of the remaining guiding rings all complete the docking operation. If the five positioning slots are installed at equal intervals on the limiting chutes, when the foremost guiding ring enters, the docking operation is completed first, and the remaining guiding rings cannot enter the inside of the outer pipe body.

[0040] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in combination with the accompanying drawings and preferred embodiments, details the specific embodiments, structures, features and their effects of the present invention as follows.

[0041] As Figures 1-10As shown in the figure, a cable saddle guiding and positioning device for a stay cable bridge includes an outer pipe body 1, a positioning frame 25 and several sets of wire dividing pipes 2. The outer pipe body 1 is located inside the positioning frame 25. The positioning frame 25 is made by welding steel frame structures, and both ends of the outer pipe body 1 and the positioning frame 25 are fixed by welding with channel steels. Several sets of wire dividing pipes 2 are all sleeved inside the outer pipe body 1. The whole of the outer pipe body 1 and several sets of wire dividing pipes 2 are both arc-shaped. Five sets of guiding rings 4 are sleeved between the outer pipe body 1 and several sets of wire dividing pipes 2. The five sets of guiding rings 4 are distributed in an arc shape, and the five sets of guiding rings 4 are arranged at equal intervals. A pipe-passing disc 9 for docking with the wire dividing pipe 2 is spliced and installed inside the guiding ring 4. Several sets of pipe-passing grooves 11 are arranged on the outer surface of the pipe-passing disc 9. The pipe-passing disc 9 and the wire dividing pipe 2 are docked with each other through the pipe-passing grooves 11.

[0042] To solve the guiding and positioning problem during the installation of the wire dividing pipe 2, as Figure 3 shown in the figure, several sets of rollers 10 are arranged on the outer surface of the guiding ring 4. The several sets of rollers 10 are distributed at equal intervals in a circular shape. A limiting sliding groove 16 for cooperating with the several sets of rollers 10 is arranged inside the outer pipe body 1. A circular notch 13 is arranged on the outer surface of the guiding ring 4. By setting the guiding ring 4 and the pipe-passing disc 9, the wire dividing pipe 2 can be installed inside the outer pipe body 1 with the same radian, which plays an auxiliary positioning role in the installation of the wire dividing pipe 2 inside the outer pipe body 1. The setting of the rollers 10 can reduce the friction between the guiding ring 4 and the outer pipe body 1 when the guiding ring 4 is installed, so that the rollers 10 move along the limiting sliding groove 16 of the outer pipe body 1.

[0043] A first anchor plate 3 is fixedly installed on the outer surface of one end of the outer pipe body 1, and a second anchor plate 6 is fixedly installed on the outer surface of the other end of the outer pipe body 1. Both the first anchor plate 3 and the second anchor plate 6 are docked and fixed through fixing bolts 7 and bolt grooves 24. Several sets of reinforcing ribs 23 are arranged on the surfaces of the first anchor plate 3 and the second anchor plate 6. The first anchor plate 3 and the second anchor plate 6 can play a role in docking and fixing between the outer pipe body 1 and the main pipe body through the fixing bolts 7.

[0044] As Figure 1 shown in the figure, reinforcing ribs 5 are installed between both the first anchor plate 3 and the outer pipe body 1 and the second anchor plate 6 and the outer pipe body 1. One end of the reinforcing rib 5 and the outer pipe body 1 are docked and fixed through a fixed hanging ear 8. The setting of the reinforcing rib 5 can improve the stability of the first anchor plate 3 and the second anchor plate 6.

[0045] To solve the installation and fixing problem of wire dividing pipes 2 with different quantities, as Figure 4As shown, an upper chuck 12 is movably installed in the middle of the upper end of the pipe threading disc 9, and a lower chuck 14 is movably installed in the middle of the lower end of the pipe threading disc 9. A docking groove 17 for cooperating with the upper chuck 12 and the lower chuck 14 is provided inside the guide ring 4. By fixing the docking groove 17 with the upper chuck 12 and the lower chuck 14, the pipe threading disc 9 can be spliced and installed inside the guide ring 4, enabling the user to install the pipe threading disc 9 with a corresponding number of pipe threading grooves 11 according to the number of wire dividing pipes 2.

[0046] Both between the lower chuck 14 and the pipe threading disc 9 and between the upper chuck 12 and the pipe threading disc 9 are elastically connected by a first spring 15. A positioning card slot 22 for cooperating with the first spring 15 is provided inside the pipe threading disc 9. By using the first spring 15, the lower chuck 14 and the upper chuck 12 can be elastically ejected, preventing the lower chuck 14 and the upper chuck 12 from resetting during docking and fixing.

[0047] As Figure 6 shown, the rollers 10 on the five groups of guide rings 4 are arranged in a staggered manner, and the total number of rollers 10 on several groups of guide rings 4 is equal to the number of limit sliding grooves 16. To ensure that the guide ring 4 can be fixed at a specified position on the outer pipe body 1 during installation, by using the arrangement of several groups of limit sliding grooves 16 in cooperation with the rollers 10, when the guide ring 4 is inserted into the outer pipe body 1 in sequence, the docking block 19 can be inserted into the specified positioning card slot 22, so that the five groups of guide rings 4 are all installed at the specified positions.

[0048] To solve the positioning problem during the installation of the wire dividing pipe 2, as Figure 8 shown, positioning card slots 22 are provided in the limit sliding grooves 16 of the outer pipe body 1. The five groups of positioning card slots 22 are arranged in an equidistant stepped staggered manner. Because the distances of the positioning card slots 22 are the same, when the guide ring 4 is installed, its docking block 19 can be inserted into the corresponding position, keeping the guide ring 4 installed at equal distances. And because the five groups of guide rings 4 are inserted into the inside of the outer pipe body 1 in sequence, by using the staggered positioning card slots 22, the five groups of positioning card slots 22 are installed on five different limit sliding grooves 16, so that after the docking block 19 of the first group of guide rings 4 completes the docking operation, the docking blocks 19 of the remaining guide rings 4 all complete the docking operation. If the five groups of positioning card slots 22 are installed at equal distances in the limit sliding grooves 16, when the foremost guide ring 4 enters, the docking operation is completed first, and the remaining guide rings 4 cannot enter the inside of the outer pipe body 1.

[0049] As Figure 7 shown, a docking block 19 is provided at the lower end of the roller 10, and the docking block 19 and the guide ring 4 are elastically connected by a second spring 20. With the arrangement of the second spring 20, the docking block 19 can be ejected outward when the roller 10 moves to the positioning card slot 22, enabling the docking block 19 to cooperate with the inclined plane chuck 18 to be inserted into the positioning card slot 22.

[0050] The working method of the wire dividing tube saddle guiding and positioning device for the cable-stayed bridge includes the following operation steps:

[0051] Step 1: Install the pipe-passing disc 9 with the corresponding number of pipe-passing grooves 11 on the inner side of the guiding ring 4 according to the number of wire dividing tubes 2, fix the wire dividing tubes 2 by welding, and successively sleeved five groups of pipe-passing discs 9 on the surface of the wire dividing tubes 2, so that the five groups of pipe-passing discs 9 are arranged at equal intervals;

[0052] Step 2: Insert the wire dividing tubes 2 into the inner part of the outer pipe body 1, so that the rollers 10 of the guiding ring 4 move along the limit sliding groove 16 of the outer pipe body 1, and fix the guiding ring 4 by the docking block 19.

[0053] During use, the traditional saddle fixes the wire dividing tube by welding, and it is necessary to control the length, bending radius and structural style of the wire dividing tube 2. When installing the wire dividing tube 22, the wire dividing tubes 2 with different bending radii are prone to dislocation, resulting in confusion during on-site installation, so that the wire dividing tubes 2 cannot maintain the same bending radius and length after overall assembly, affecting the subsequent steel cable installation effect, and at the same time, it cannot be flexibly applied to the installation operations of wire dividing tubes 2 with different numbers, reducing the flexibility during its installation and use;

[0054] By setting the outer pipe body 1 and the guiding ring 4, when installing the wire dividing tubes 2 of the cable-stayed bridge, several groups of wire dividing tubes 2 can be uniformly installed inside the outer pipe body 1, and the guiding ring 4 can accurately control the installation position and bending radius of the wire dividing tubes 2, so that several groups of wire dividing tubes 2 are accurately combined;

[0055] During operation, by setting the guiding ring 4 and the pipe threading disc 9, the wire splitting pipe 2 can be installed on the inner side of the outer pipe body 1 with the same radian, which plays an auxiliary positioning role in the installation of the wire splitting pipe 2 inside the outer pipe body 1. The setting of the roller 10 can reduce the friction between the guiding ring 4 and the outer pipe body 1 when the guiding ring 4 is installed, so that the roller 10 moves along the limiting chute 16 of the outer pipe body 1. According to the number of wire splitting pipes 2, the pipe threading disc 9 with corresponding number of pipe threading grooves 11 is installed on the inner side of the guiding ring 4. Five groups of pipe threading discs 9 are successively sleeved on the surface of the wire splitting pipe 2, and the five groups of pipe threading discs 9 are kept at equal intervals. Then the wire splitting pipe 2 is inserted into the inner part of the outer pipe body 1, so that the roller 10 of the guiding ring 4 moves along the limiting chute 16 of the outer pipe body 1. The guiding ring 4 is fixed by the docking block 19, and grout is injected into the outer pipe body 1 to fix between the outer pipe body 1 and the wire splitting pipe 2, so that the outer pipe body 1 and the wire splitting pipe 2 are integrated. The outer pipe body 1 can play a certain protective role for the wire splitting pipe 2 to avoid the rust phenomenon of the wire splitting pipe 2. At the same time, by using several groups of pipe threading grooves 11 in the pipe threading disc 9, it can play a positioning role in the installation between several groups of wire splitting pipes 2. The setting of the guiding ring 4 can make the combined wire splitting pipe 2 located in the middle position of the outer pipe body 1, and at the same time make the wire splitting pipe 2 and the outer pipe body 1 have the same bending radius, which plays an accurate control on the installation position of the wire splitting pipe 2 and avoids the confusion phenomenon during the installation between several groups of wire splitting pipes 2;

[0056] By setting the pipe threading disc 9, when the wire splitting pipe 2 saddle guiding and positioning device of the cable-stayed bridge is used, the use of the guiding ring 4 is optimized, and the inner side of the guiding ring 4 has a spliced fixed structure, which can make it flexibly install any number of wire splitting pipes 2 for use, improving its flexibility during use;

[0057] During use, the docking groove 17 can be fixed by using the upper chuck 12 and the lower chuck 14, and the pipe threading disc 9 can be spliced and installed on the inner side of the guiding ring 4, so that the user can install the pipe threading disc 9 with corresponding number of pipe threading grooves 11 according to the number of wire splitting pipes 2. The user sleeved the pipe threading disc 9 on the middle position of the guiding ring 4. The first spring 15 can elastically eject the lower chuck 14 and the upper chuck 12, so that the lower chuck 14 and the upper chuck 12 are respectively inserted into the docking grooves 17 above and below the guiding ring 4, avoiding the reset phenomenon when the lower chuck 14 and the upper chuck 12 are docked and fixed, making it possible to install the pipe threading disc 9 with any number of pipe threading grooves 11 for use. At the same time, by using several groups of circular notches 13 arranged on the surface of the guiding ring 4, when grouting operation is carried out inside the outer pipe body 1, the grout can uniformly flow into the inner part of the outer pipe body 1.

[0058] By setting the docking block 19 and the positioning slot 22, when the cable saddle guiding and positioning device of the stay cable pipe 2 of the cable-stayed bridge is used, the use effects of the outer pipe body 1 and the guiding ring 4 are improved, the installation positions of the guiding ring 4 and the stay cable pipe 2 in the outer pipe body 1 are accurately controlled, and the installation accuracy of the whole cable structure is improved;

[0059] During operation, to ensure that the guiding ring 4 can be fixed at a specified position on the outer pipe body 1 during installation, the arrangement of a number of groups of limiting chutes 16 and rollers 10 can make the docking block 19 inserted into the specified positioning slot 22 when the guiding ring 4 is successively inserted into the outer pipe body 1, so that all five groups of guiding rings 4 are installed at the specified positions. Because the distances of the positioning slots 22 are the same, when the guiding ring 4 is installed, its docking block 19 can be inserted into the corresponding position to keep the guiding rings 4 installed at equal distances. Since the five groups of guiding rings 4 are successively inserted into the inside of the outer pipe body 1, the positioning slots 22 are arranged in a staggered manner, and the five groups of positioning slots 22 are installed on five different limiting chutes 16, so that after the docking block 19 of the first group of guiding rings 4 completes the docking operation, the docking blocks 19 of the remaining guiding rings 4 all complete the docking operation. If the five groups of positioning slots 22 are installed at equal intervals on the limiting chutes 16, when the foremost guiding ring 4 enters, the docking operation is completed first, and the remaining guiding rings 4 cannot enter the inside of the outer pipe body 1.

[0060] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention.
