DETAILED DESCRIPTION

[0017] Example 1 like Figure 1-4 As shown, a large-diameter drainage pipe threading device for a steel beam flange includes a steel box beam 1, a steel box beam flange 2 at the edge of the steel box beam 1, and a drainage pipe 6. The bottom of the steel box beam flange 2 is provided with a mounting hole 3 for mounting the drainage pipe 6. This is a prior art in the art, so it will not be described in detail here. The installation platform of this embodiment realizes efficient installation of large-diameter drainage pipes through the following components and steps: The installation truss 4 is fixedly arranged on the end face of the steel box girder 1. The installation truss 4 can bear the load during the installation process and provide a stable working environment for the installation of the drainage pipe 6. The upper chord and the lower chord of the installation truss 4 are fixedly arranged on the end face of the steel box girder 1. The reinforcing plates 14 distributed on the four sides are arranged at the consolidation points of the upper chord and the lower chord of the installation truss 4 and the steel box girder 1 to enhance the torsion resistance of the node.

[0018] The mounting platform 5 is an outwardly extending structure, fixedly mounted on the outside of the mounting truss 4 and corresponding to the mounting hole 3 , and is used to guide the installation of the drain pipe 6 . The size of the mounting platform 5 meets the installation requirements of the drain pipe 6 .

[0019] A traction connection member 9 is arranged on the drainage pipe 6 to be installed; The winch 8 is arranged on the bridge deck of the steel box girder flange 2 and is located above the mounting hole 3 . The pull rope on the winch is connected to the traction connector 9 through a pulley 10 .

[0020] With such a design, the drain pipe 6 can be hoisted onto the installation platform 5 by the hoisting equipment and aligned with the installation hole 3, and then the pull rope of the winch 8 is connected to the traction connector 9 through the pulley 10 to provide traction for the through-hole of the drain pipe 6, thereby completing the installation of the drain pipe 6. There is no need for construction workers to stand in the hanging basket to perform the perforation installation of the drain pipe 6, thereby achieving efficient and safe installation of large-diameter drain pipes.

[0021] Among them, the walkway board 11 on the top of the installation truss 4 and the guardrail 12 surrounding the top thereof facilitate the formation of a safe working passage on the top of the installation truss 4, thereby assisting the installation of the drainage pipe 6.

[0022] In the preferred embodiment, the installation platform 5 is composed of a plurality of support units arranged equidistantly, and the support unit includes a support rod 501 fixedly mounted on the outside of the installation truss 4, and the support rod 501 is used to support the drain pipe 6 to be installed from the bottom, and the other end of the support rod 501 is provided with a baffle 503 extending upward, and the baffle 503 plays a limiting role to prevent the drain pipe 6 from falling. A supporting diagonal rod 502 is also fixedly arranged between the bottom of the support rod 501 and the installation platform 5, thereby forming a stable triangular structure, which can improve its structural strength.

[0023] In addition, the top of the upper chord of the mounting truss 4 is higher than the bottom of the drain pipe, and also serves as a limit for the inner side of the drain pipe.

[0024] In the preferred solution, a plurality of cables 13 connected to the bridge deck of the steel box girder 1 are also provided at one end of the installation truss 4 away from the steel box girder 1 to enhance the stability of the truss and avoid excessive deflection of the cantilever end, which may cause deformation and affect the pipe threading work.

[0025] In this embodiment, the traction connecting member 9 is a steel wire rope tied to the outside of the drain pipe 6. The steel wire rope prevents the pulley 10 from moving during the traction process through static friction. At the same time, during the traction process, the traction installation of all the drain pipes 6 is completed by tying the steel wire rope to different drain pipes 6 in turn.

[0026] Example 2 Further illustrate with reference to Example 1, Figure 5-7 In order to improve the through-hole capability of the front end of the first drain pipe 6 , the structure shown in this embodiment also includes a guide device 7 , which is arranged at the front end of the first drain pipe 6 and is used to align the first drain pipe 6 with the installation hole 3 .

[0027] Furthermore, the guide device 7 includes a mounting base that can be plugged into the end of the drain pipe 6, a guide cone guide head arranged on the mounting base, and a plurality of distance measuring devices arranged on the guide cone guide head.

[0028] With such a design, the guide device 7 is installed at the front end of the drain pipe 6 through the mounting base, and the conical design of the guide cone guide head facilitates the guiding role in the through hole. The distance measuring device can play a role in real-time measurement and positioning, making it convenient for the installer to adjust the position of the drain pipe 6.

[0029] Among them, the installation base includes a plug-in ring 701 and a contact ring 702 that are connected. The outer diameter of the plug-in ring 701 is adapted to the inner diameter of the drain pipe 6, and the outer diameter of the contact ring 702 is adapted to the outer diameter of the drain pipe 6. Therefore, the installation between the two can be achieved through the static friction between the plug-in ring 701 and the drain pipe 6. It should be noted that when the front end of the drain pipe 6 is closed by the pipe cover, the plug-in ring 701 is plugged into the pipe cover, and the pipe cover is a concave inner plug-in cover.

[0030] The guide cone guide head is composed of a plurality of inclined rods 703 connected at the ends, the other end of the inclined rod 703 is connected to the abutment ring 702, and a connecting rod 704 is arranged between the inclined rods 703 to form a conical design. In the present embodiment, the number of the inclined rods 703 is four, and the four inclined rods 703 are equidistantly distributed in a ring, and the connecting ends of the four inclined rods 703 are pointed, and the connecting rod 704 effectively enhances the stability between the four inclined rods 703.

[0031] The tilt rod 703 is provided with a through slot 705 for distance measurement. The number of the distance measuring devices is adapted to the number of the tilt rods 703, which includes a fixing plate 706 arranged on the inner side of the tilt rod 703. A distance measuring sensor 707 with a measuring end located in the through slot 705 is penetrated on the fixing plate 706. The measuring end of the distance measuring sensor 707 is lower than the outer side surface of the tilt rod 703. In the present embodiment, the number of the distance measuring sensors 707 is four, and they are all ultrasonic sensors.

[0032] With such a design, the through groove 705 provides conditions for the measurement of the distance measuring sensor 707, so that the four ultrasonic sensors on the guide device 7 can be used to measure the distances between the four points of the guide head and the edge of the mounting hole 3 in real time during the through-hole process. If the data exceeds the limit, manual correction is performed in a timely manner based on the real-time data. In addition, the design that the measuring end is lower than the outer side of the tilting rod 703 can prevent unnecessary collision with the distance measuring sensor 707 when the tilting rod 703 collides with the edge of the mounting hole 3.

[0033] In the preferred embodiment, a plurality of locking components evenly distributed in an annular manner are provided on the plug-in ring 701 to improve the strength of its connection with the drain pipe 6. In this embodiment, the number of the locking components is four, and the locking components are staggered with the tilt rod 703 to facilitate adjustment therewith.

[0034] The locking assembly includes an internal threaded shaft 708 arranged on the inner side of the plug-in ring 701, and a hole connected to the internal threaded shaft 708 is arranged on the plug-in ring 701. A locking bolt 709 is threadedly installed in the internal threaded shaft 708. The end of the locking bolt 709 can pass through the hole on the plug-in ring 701 and contact the inner wall of the drain pipe 6, and a rubber pad is provided.

[0035] When in use, the locking bolt 709 can be rotated to expand and contract in the internal threaded shaft 708, so that the rubber pad at its end can come into contact with the inner wall of the drain pipe 6, thereby improving the connection strength. In addition, the rubber pad can increase the connection friction while preventing unnecessary damage to the inner wall of the drain pipe 6.

[0036] Example 3 Further illustrate with reference to Examples 1 and 2, Figure 8-17 As shown in the structure, this embodiment provides a second embodiment of the traction connector 9, which can adjust its connection with the drain pipes 6 in different installation sequences by self-movement during the traction process of the drain pipe 6, without the need for manual adjustment.

[0037] Furthermore, the traction connector 9 includes two self-propelled mechanisms 92 arranged outside the drain pipe 6 and a binding mechanism 91 arranged between the two self-propelled mechanisms 92, wherein the self-propelled mechanism 92 is used to control the movement of the traction connector 9 on the drain pipe 6, and the binding mechanism 91 is used to bind and connect it to or unbind it from the drain pipe 6. In addition, the three are fixedly connected.

[0038] In the preferred embodiment, the binding mechanism 91 includes an outer ring 910 and a rotating ring 911 rotatably disposed in the outer ring 910. The inner diameters of the outer ring 910 and the rotating ring 911 are both larger than the drain pipe 6, and both are provided with notches. The notches facilitate avoiding the connection between the drain pipe 6 and the mounting platform 5 when the outer ring 910 moves on the drain pipe 6. It should be noted that in this embodiment, the arc lengths of the outer ring 910 and the rotating ring 911 are the same.

[0039] The inner ring side of the two and both ends of the gap of the outer ring 910 are open. A starting rod 912 is provided at the opening of the inner ring side of the outer ring 910, and the starting rod 912 is located on the inner side of the rotating ring 911. A self-recovery mechanism 913 is provided in the middle of the rotating ring 911. A binding rope 917 is wound in the self-recovery mechanism 913, and the other end of the binding rope 917 is connected to the starting rod 912. A gear ring 914 is provided at an edge of the outer ring side of the rotating ring 911, and a plurality of rotating drive mechanisms 915 connected to the gear ring 914 are provided in the outer ring 910. In this embodiment, the number of the rotating drive mechanisms 915 is three, and they are respectively arranged at the center of the arc top and at both ends of the gap.

[0040] It should be noted that the self-recovery mechanism 913 in this embodiment is a spring self-recovery structure of the tape measure, which contains a coil spring, one end of which is fixed to the central axis inside, and the other end is fixed to the end of the binding rope 917. When the rotating ring 911 rotates in the outer ring 910, due to the restraining effect of the starting rod 912, the binding rope 917 is pulled out, and at the same time, the coil spring is driven to rotate and stretch. The spring is tightened in this process and stores elastic potential energy. When the rotating ring 911 rotates, it returns to its original state through the coil spring, releasing the stored energy, thereby driving the binding rope 917 to quickly reel back into it. This is a mature existing technology, so it will not be described in detail here.

[0041] With such a design, the inner ring sides of the outer ring 910 and the rotating ring 911 are both open, which facilitates the direct contact between the binding rope 917 and the drain pipe 6. At the same time, both ends of the notch of the outer ring 910 are open, which provides conditions for the rotation of the rotating ring 911 in the outer ring 910. Through the rotation of the rotating ring 911 in the outer ring 910, the binding rope 917 can be bound to the outside of the drain pipe 6, thereby forming a connection between the two. When the rotating ring 911 rotates, the binding rope 917 can be recovered to release its binding relationship with the drain pipe 6. The three rotating drive mechanisms 915 can ensure that the rotating ring 911 always maintains two or more power outputs during the rotation process, thereby improving its rotation stability.

[0042] In the preferred embodiment, a plurality of rotatable auxiliary rotation wheels 916 are further provided in the outer ring 910, and the auxiliary rotation wheels 916 are in contact with the other edge of the outer ring side of the rotating ring 911. In this embodiment, the number of auxiliary rotation wheels 916 is four, and two are distributed in a group on both sides of the central rotating drive mechanism 915. The auxiliary rotation wheels 916 can further improve the rotation stability of the rotating ring 911.

[0043] In the preferred embodiment, the rotating drive mechanism 915 includes a transmission gear 9150 rotatably arranged in the outer ring 910 and meshing with the gear ring 914, and a driving motor 9151 with a brake arranged on the outside of the outer ring 910 and connected to the transmission gear 9150. When in use, the driving motor 9151 can drive the transmission gear 9150 to rotate, and after the bundling is completed, the bundling state can be locked by utilizing its own braking effect. It should be noted that the driving motors 9151 of the three rotating drive mechanisms 915 maintain the same frequency rotation when driven.

[0044] In the preferred embodiment, the self-propelled mechanism 92 includes a fixed arc plate 920 and two clamping arc plates 921 respectively hingedly arranged at both ends of the fixed arc plate 920. A gap is formed between the other ends of the two clamping arc plates 921. The gap is used to avoid the connection between the drain pipe 6 and the installation platform 5. The inner ring side of the fixed arc plate 920 is provided with a self-driving walking wheel 925. The self-driving walking wheel 925 is a walking wheel with a walking motor. This is a conventional commercial product and is not described in detail here. The inner ring side of the end of the clamping arc plate 921 away from the fixed arc plate 920 is provided with a walking auxiliary wheel 926. The self-driving walking wheel 925 and the walking auxiliary wheel 926 are both fitted with the drain pipe 6, and both are arc-shaped wheels adapted to the outside of the drain pipe 6, which can effectively increase the contact area. An extension plate 922 is provided on the outer ring side of the clamping arc plate 921, and two symmetrical clamping telescopic bars 923 are hingedly provided on the outer ring side of the fixed arc plate 920. The other end of the clamping telescopic bar 923 is hinged to the corresponding extension plate 922. The clamping arc plate 921 can be clamped on the outside of the drain pipe 6 by the clamping telescopic bar 923, so that the walking auxiliary wheel 926 can remain in fit with the outside of the drain pipe 6. At the same time, through clamping, unnecessary rotation of the whole can be prevented when the binding mechanism 91 is binding.

[0045] With such a design, when mobility is needed, the binding of the contact binding mechanism 91 can be achieved, and the self-driving walking wheels 925 can be used to drive the entire device to move on the drain pipe 6, thereby moving to the next binding position. It should be noted that the width of the mounting platform 5 meets the walking requirements of the traction connector 9 in this embodiment.

Repeat step S3 until all drain pipes are installed.
