[0002] As an important part of bridge engineering, bridge drainage pipes mainly function to timely drain accumulated water during rainfall or when there is water on the bridge surface, preventing water from seeping into the internal structure of the bridge and avoiding damage to the durability and safety of the bridge. As a specific installation method of the drainage pipes, they are distributed along the length direction of the bridge at the bottom of the bridge and are connected to the top of the bridge through multiple longitudinal pipe bodies, so as to collect the accumulated water discharged from the top of the bridge. Through reasonable layout and design, the efficient operation of the drainage system is ensured, thereby extending the service life of the bridge and reducing maintenance costs.

Detailed implementation manners

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments.

[0048] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this invention belongs. The terms used in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit the invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0049] As Figures 1 to 8 shown, a bridge drain pipe lifting device includes:

[0050] A vehicle body 03, which is suspended outside the bridge crash barrier 01 and is movably arranged along the arrangement direction of the drain pipe 02, and the vehicle body 03 provides an operating position for the operator at the bottom of the bridge;

[0051] A lifting assembly, including a lifting frame 04 and a hoisting structure 05. The lifting frame 04 is installed outside the vehicle body 03 and includes a sliding part 041 and a rotating part 042;

[0052] The sliding part 041 is linearly slidably connected to the vehicle body 03 and receives the up-and-down moving power provided by the hoisting structure 05; the rotating part 042 is rotatably connected to the sliding part 041 through a longitudinal rotating shaft. When the rotating part 042 fits with the sliding part 041, it carries the drain pipe 02 loaded from the top of the bridge and moves, and, after the drain pipe 02 descends to the installation height, it rotates relative to the sliding part 041 so that the drain pipe 02 rotates from the outside of the vehicle body 03 to the inside.

[0053] In this invention, through the design of suspending the vehicle body 03 outside the bridge crash barrier 01 and the coordinated action of the sliding part 041 and the rotating part 042 of the lifting assembly, the problems of complex structure and high cost of traditional drain pipe 02 lifting vehicles are solved. During operation, the vehicle body 03 moves along the arrangement direction of the drain pipe 02, providing an operating position at the bottom of the bridge for the operator. The lifting frame 04 drives the sliding part 041 to move up and down through the hoisting structure 05, and when the rotating part 042 rotates with the sliding part 041 through the longitudinal rotating shaft, the precise transfer of the drain pipe 02 from the outside to the inside is realized; not only the equipment structure is simplified, the equipment cost is reduced, but also the installation efficiency and flexibility are greatly improved in the bridge construction environment with limited space.

[0054] Specifically, before using the above bridge drain pipe 02 lifting device for work, it is necessary to suspend the vehicle body 03 of the device outside the bridge crash barrier 01, ensure that the moving direction of the vehicle body 03 is consistent with the arrangement direction of the bridge drain pipe 02, and the suspension of the vehicle body 03 should be firm and reliable to ensure that there will be no shaking or falling during the movement and lifting process, and ensure the safety of the drain pipe 02 lifting operation.

[0055] After the assembly is completed, the lifting work of the drain pipe 02 can be carried out through this device. First, the vehicle body 03 needs to be moved to the set position at the top of the bridge. This set position should be correspondingly set with the end position of the previous section of the drain pipe 02, so that the operator can stand on the working position of the vehicle body 03 and complete the connection and assembly work of the next section of the drain pipe 02; the movement of the vehicle body 03 along the arrangement direction of the drain pipe 02 can be realized by an electric or manual drive system. During the movement, it can be controlled by the operator at the position above the bridge collision wall 01, or directly by the operator at the working position of the vehicle body 03 at the bottom of the bridge, ensuring that the vehicle body 03 can accurately reach the position where the drain pipe 02 needs to be assembled.

[0056] Next, the operator can lift the lifting frame 04 to the top of the sliding path of the sliding part 041 through the hoisting structure 05. The lifting frame 04 is installed outside the vehicle body 03, used to receive the drain pipe 02 at the top and transfer it to the assembly position at the bottom of the bridge, and ensure its stability; the hoisting structure 05 provides power for the lifting frame 04 to drive the sliding part 041 to move up and down. Generally, the hoisting structure 05 is usually driven by an electric motor, and the operator can operate through the control panel or remote control to ensure that the sliding part 041 can be smoothly lifted and lowered to the specified position.

[0057] When the sliding part 041 is at the top of the sliding path, the rotating part 042 is at the top of the bridge. The operator can load the drain pipe 02 onto the rotating part 042 on the bridge to ensure the convenience and stability of loading the drain pipe 02; after the assembly is completed, the hoisting structure 05 drives the lifting frame 04 to descend until the drain pipe 02 descends to the installation height. During the process of carrying and transporting the drain pipe 02, the rotating part 042 fits with the sliding part 041 to ensure that the drain pipe 02 will not shake or fall off during the lifting process; during the lifting process, the operator needs to closely monitor the position and state of the drain pipe 02 to ensure its smooth descent.

[0058] When the drain pipe 02 descends to the installation height, the operator can apply force to the rotating part 042 or the drain pipe 02 at the working position to drive the drain pipe 02 to rotate from the outside of the vehicle body 03 to the inside. During this process, the rotating part 042 rotates 0° to 180° relative to the sliding part 041 through the longitudinal rotating shaft, so that the drain pipe 02 reaches the inside position where it can be assembled. During the rotation, the operator needs to ensure that the rotation action is stable to avoid the drain pipe 02 colliding with the surrounding structures.

[0059] After the drain pipe 02 rotates to the inside, the operator installs the drain pipe 02 to the predetermined position. During the installation process, it is necessary to ensure that the connection of the drain pipe 02 is firm and the sealing performance is good to avoid problems such as water leakage in the future. At the installation position, the operator can accurately position the drain pipe 02 through the auxiliary device and complete the fixation through the expansion bolts, thus completing the lifting and assembly operation of a single drain pipe 02.

[0060] After the installation is completed, the operator needs to check the drain pipe 02 to ensure that its installation quality meets the requirements. At the same time, check the lifting device to ensure that all its components are working properly and get ready for the next operation. At this time, the operator can apply a reverse force to the rotating part 042 at the working position, so that the rotating part 042 fits with the sliding part 041 again. After the vehicle body 03 moves to the next set position, the hoisting structure 05 drives the sliding part 041 to rise again, preparing for the next hoisting and assembling operation of the drain pipe 02.

[0061] On the basis of the above embodiments, the lifting frame 04 further includes a magnetic attraction structure, which is arranged on the rotating part 042 and / or the sliding part 041, and provides a set magnetic attraction force for the sliding part 041 and the rotating part 042 through a permanent magnet; arranging a magnetic attraction structure on the rotating part 042 and / or the sliding part 041 of the lifting frame 04, such as embedding a permanent magnet or using an annular magnetic attraction component, can provide a stable magnetic attraction force during the lifting process, ensure the close fit of the sliding part 041 and the rotating part 042, and at the same time does not affect the rotation of the rotating part 042.

[0062] Specifically, the specific structural form of the magnetic attraction structure can be set as a structure of arranging an iron adsorption plate on the end face of the sliding part 041, or embedding a permanent magnet in an annular groove opened on the contact surface of the rotating part 042; this not only improves the stability of the lifting process, but also simplifies the operation steps and reduces manual intervention.

[0063] On the basis of the above embodiments, the rotating part 042 includes a base body 0421, a carrier 0422 and a telescopic body 0423;

[0064] The base body 0421 is rotatably connected to the sliding part 041. The carrier 0422 radially limits the drain pipe 02 through a groove structure. The telescopic body 0423 connects the base body 0421 and the carrier 0422, and adjusts the distance between the base body 0421 and the carrier 0422 by adjusting the telescopic length.

[0065] The base body 0421, as the core component of the rotating part 042, is connected to the sliding part 041 through a longitudinal rotating shaft, providing stable rotational support to ensure that the rotating part 042 can rotate smoothly; the carrier 0422 radially positions the drain pipe 02 through a groove structure to ensure that the drain pipe 02 does not shake or fall off during rotation and lifting, improving the installation accuracy and safety; the telescopic body 0423 adjusts the distance between the base body 0421 and the carrier 0422, and can flexibly move the drain pipe 02 to the docking position with the end of the previous drain pipe 02 during the assembly of the drain pipe 02, so as to adapt to drain pipes 02 of different diameters and lengths, increasing the versatility and flexibility of the device; the combination of the base body 0421, the carrier 0422 and the telescopic body 0423 provides stable support and precise positioning for the drain pipe 02, ensuring the stability of the drain pipe 02 during rotation and lifting, and improving the accuracy, efficiency, flexibility and safety of installation.

[0066] Specifically, the carrier 0422 can adopt a U-shaped, V-shaped limiting groove or a modular clamp structure, or a radial clamping device is provided in the groove structure, and the telescopic body 0423 is preferably a hydraulic push rod or a lead screw mechanism; enabling the drain pipe 02 to achieve dual control of radial limit and axial adjustment during the hoisting process, significantly improving the installation accuracy and adaptability.

[0067] Based on the above embodiments, it further includes a limiting structure fixedly connected to the vehicle body 03, and the limiting structure independently provides a limiting space, or provides a limiting space together with the vehicle body 03;

[0068] During the movement of the crane 04, the limiting space restricts the sliding part 041 and the rotating part 042 to remain in a fitting state.

[0069] The limiting structure ensures that the sliding part 041 and the rotating part 042 always remain in a fitting state during movement, improving the stability of the device and the installation accuracy of the drain pipe 02, ensuring the stability of the drain pipe 02 during lifting and rotation, and also reducing the risk of deviation caused by vibration or wind, significantly enhancing the applicability of the equipment in complex environments. Specifically, the specific form of the limiting structure includes welding a U-shaped limiting card slot on the side wall of the vehicle body 03, with a compact structure and reliable limiting.

[0070] Based on the above embodiments, the vehicle body 03 includes a frame structure 031 and a wheel assembly 032;

[0071] The frame structure 031 provides a standing position and a position for linear sliding connection with the sliding part 041, and the wheel assembly 032 is fixedly connected to the frame structure 031;

[0072] There are at least three groups of wheel assemblies 032 distributed on the vehicle body 03, and each group of wheel assemblies 032 includes at least two. The three groups of wheel assemblies 032 are respectively attached to the outer surface, top surface and inner surface of the anti-collision wall 01.

[0073] The frame structure 031 provides a working position for the operator and a connection position with the sliding part 041. The wheel assembly 032 includes at least three groups, which are respectively attached to the outer surface, top surface and inner surface of the anti-collision wall 01 to form a three-dimensional constraint, ensuring that the vehicle body 03 remains stable during movement, preventing tilting or shaking, improving the safety and stability of the device, reducing the risks during construction, and at the same time ensuring the precision and quality of construction; specifically, the specific structural form of the wheel group assembly can be set as a universal wheel group or a spring suspension wheel group, which can adapt to the uneven surface of the bridge anti-collision wall 01, improve the environmental adaptability and versatility of the device and the stability and safety of the movement of the vehicle body 03. At the same time, the wheel assembly 032 converts the sliding friction between the frame structure 031 and the anti-collision wall 01 into rolling friction, facilitating the transfer of the vehicle body 03 and reducing the labor intensity of the operator.

[0074] On the basis of the above embodiment, the hoisting structure 05 is installed on the top of the frame structure 031; by optimizing the rope-out angle of the steel wire 051, the off-load friction is reduced and the service life of the steel wire 051 is extended. In addition, a cross-shaped reinforcing rib can be provided on the top of the frame structure 031 to improve the bearing capacity, or a rain-proof cover structure can be integrated to protect the hoisting mechanism, which not only improves the operation convenience but also enhances the applicability of the equipment in harsh environments.

[0075] On the basis of the above embodiment, the vehicle body 03 further includes a guiding structure 033 for guiding the transmission direction of the steel wire 051 led out from the hoisting structure 05;

[0076] The guiding structure 033 is one of a rotatably arranged rod body or a wheel body.

[0077] By guiding the transmission direction of the steel wire 051, the guiding structure 033 avoids the deviation or winding of the steel wire 051 during the transmission process, ensures the smooth and reliable transmission of the steel wire 051, thereby improving the operation precision of the hoisting mechanism and the smoothness of the lifting action of the lifting frame 04; specifically, the specific form of the guiding structure 033 can be set as the structure form of an adjustable-angle guiding rod or a compound pulley group, and the appropriate guiding structure 033 can be selected according to the size structure of the drain pipe 02 and the construction environment to adjust the running direction of the steel wire 051, which can not only reduce the wear of the steel wire 051, extend the service life of the device, but also improve the stability and efficiency of the hoisting process.

[0078] On the basis of the above embodiment, the frame structure 031 includes a guardrail 0311, which is arranged around the standing position to limit the standing space of the operator, thereby improving the safety of the operator. The guardrail 0311 can be designed in a lifting style or a modular quick-release structure, which is convenient for adjusting the height or disassembly according to construction requirements. Specifically, it can be arranged as a telescopic structure supported by a gas pressure rod or a buckle connection of an aluminum alloy rod. Thus, the safety of the operator is improved while enhancing the flexibility and adaptability of the equipment.

[0079] The present invention also provides a working method of a bridge drainage pipe lifting device, using the bridge drainage pipe lifting device as above, comprising the following steps:

[0080] A1: Move the vehicle body 03 to the set position on the top of the bridge; during the movement, the wheel assembly 032 of the vehicle body 03 must fit tightly against the outer surface, top surface and inner surface of the crash barrier 01 to ensure the stability and balance of the vehicle body 03 during the movement. During the movement, the operator must pay attention to the surrounding environment to avoid collision with other structures;

[0081] A2: The hoisting frame 04 is hoisted to the top of the sliding path of the sliding part 041 by the hoisting structure 05; during the lifting process of the hoisting frame 04, the operator needs to pay close attention to the position and state of the sliding part 041 to ensure that it rises smoothly and avoids shaking or tilting; the steel wire 051 of the hoisting structure 05 can be guided by the guide structure 033 under the set scenario to ensure that the transmission direction of the steel wire 051 is stable;

[0082] A3: Load the drain pipe 02 onto the rotating part 042 on the bridge; during the loading process, the operator needs to ensure the stability of the connection between the drain pipe 02 and the rotating part 042 to avoid loosening during the lifting and rotating process; when the bridge drain pipe lifting device is optimized to use the bearing body 0422, when implementing this step, the bearing body 0422 of the rotating part 042 can be adjusted according to the diameter and length of the drain pipe 02 to ensure that the drain pipe 02 can be stably loaded;

[0083] A4: The hoisting structure 05 drives the lifting frame 04 to descend until the drain pipe 02 descends to the installation height. During the descent of the lifting frame 04, the operator needs to pay close attention to the position and state of the drain pipe 02 to ensure that it descends smoothly and avoids shaking or tilting. The descent speed of the hoisting structure 05 needs to be adjusted according to the actual situation to ensure that the drain pipe 02 can accurately reach the installation height.

[0084] A5: At the working position, by applying force to the rotating part 042 or the drain pipe 02, the drain pipe 02 is driven to rotate from the outside of the vehicle body 03 to the inside; during the rotation process, the operator needs to ensure that the rotation action is stable to avoid the drain pipe 02 colliding with the surrounding structures; the rotation angle of the rotating part 042 needs to be adjusted according to the actual installation position to ensure that the drain pipe 02 can accurately reach the inside position;

[0085] A6: Move the drain pipe 02 to reach the installation position; during the movement, the drain pipe 02 can be separated from the rotating part 042 or remain in the installed state relative to the rotating part 042; specifically, in the ideal state of this installation position, the end face of the drain pipe 02 to be installed should be set opposite to the end face of the previous section of the drain pipe 02, and their axes should be collinear. During the movement, the operator needs to closely monitor the distance between the drain pipe 02 and the surrounding structures to avoid collisions.

[0086] After moving to the installation position, the drain pipe 02 can be fixed to the connecting component using bolts, welding or other connection methods to ensure that the connection is firm and reliable. During the connection process, the operator needs to check the sealing performance of the connection to avoid problems such as water leakage in the future and ensure that its installation quality meets the requirements; after the installation is completed, the operator reconnects the rotating part 042 and the sliding part 041, and the hoisting structure 05 drives the sliding part 041 to rise, and the lifting frame 04 returns to its original position to prepare for the next operation.

[0087] The above working method includes steps such as positioning the vehicle body 03, lifting the lifting frame 04, loading the drain pipe 02, lowering it to the installation height, rotating it to the inside, and moving it to the installation position, controlling the precise movement of the sliding part 041 and the flexible rotation of the rotating part 042, realizing the efficient installation of the drain pipe 02; when working, the vehicle body 03 moves along the arrangement direction of the drain pipe 02, providing a working position at the bottom of the bridge for the operator. The lifting frame 04 drives the sliding part 041 to move up and down through the hoisting structure 05, and when the rotating part 042 and the sliding part 041 rotate through the longitudinal rotating shaft, the precise transfer of the drain pipe 02 from the outside to the inside is realized.

[0088] The present invention also provides a working method for a bridge drain pipe lifting device, using the above bridge drain pipe 02 lifting device, including the following steps:

[0089] B1: Move the vehicle body 03 to the set position at the top of the bridge;

[0090] B2: Lift the lifting frame 04 to the top of the sliding path of the sliding part 041 through the hoisting structure 05;

[0091] B3: Load the drain pipe 02 onto the rotating part 042 on the bridge;

[0092] B4: Drive the lifting frame 04 to descend through the hoisting structure 05 until the drain pipe 02 descends to the installation height;

[0093] B5: Apply force to the rotating part 042 or the drain pipe 02 at the working position to drive the drain pipe 02 to rotate from the outside of the vehicle body 03 to the inside;

[0094] B6: Move the drain pipe 02 to reach the installation position.

[0095] Among them, during the process of moving the drain pipe 02, the bearing of the drain pipe 02 by the rotating part 042 is maintained. The movement includes moving the drain pipe 02 along the axial direction of the drain pipe 02, and synchronously moving the carrier 0422 and the drain pipe 02 along the telescopic direction of the telescopic body 0423.

[0096] The above working method further optimizes the control method during the movement of the drain pipe 02. Using the combined rotating part 042 as an auxiliary tool for the final positioning of the drain pipe 02 is superior to removing the drain pipe 02 from the rotating part 042 during the installation process. Through the length adjustment of the telescopic body 0423, the axial and radial synchronous movement of the drain pipe 02 can be realized, which can drive the drain pipe 02 to move to the vertical plane where the installation position is located and be collinear with the axis of the upper section of the drain pipe 02. At this time, the drain pipe 02 can be moved along the axial direction of the drain pipe 02 to butt the end faces of the two sections of the drain pipe 02, and the drain pipe 02 can be fixed through additional connecting parts. During this process, precise adjustment can be achieved through the lead screw mechanism or the hydraulic push rod, reducing the adjustment time of the operator, significantly improving the accuracy and efficiency of the movement, and greatly improving the applicability of the installation of complex bridge structures or special-shaped pipes.
