Description

Technical Field

[0001] This utility model relates to the field of pipeline hoisting equipment technology, and in particular to a pipeline auxiliary docking device used in hoisting. Background Technology

[0002] In municipal engineering construction, the installation of drainage pipes is a key link to ensure the normal operation of the urban drainage system. Usually, a crane is used to lift the pipe to be connected to a preset height, align it with the port of the already installed pipe, and then insert, weld or flange it to form a continuous delivery pipeline.

[0003] In current drainage pipeline hoisting operations, during pipeline hoisting and docking, the connection between the pipeline and the crane hook is usually flexible (such as simple wire rope binding). Relying solely on the lifting and rotation of the crane makes it difficult to achieve high-precision alignment of the pipeline ends. The pipeline is prone to swaying and tilting in the air, leading to docking deviations. Manual adjustment with tools such as crowbars and ropes is required, which not only increases the labor intensity of the workers, but also, although existing pipeline docking auxiliary equipment can replace manual adjustment to a certain extent, it generally suffers from complex structure and heavy weight, making on-site handling and deployment cumbersome and limiting the construction progress.

Detailed Implementation

[0018] Below, in conjunction with the appendix Figure 1 To be continued Figure 5 The present invention will be further described in detail below, along with specific implementation methods. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0019] A pipe hoisting and docking adjustment device includes a track frame structure 1, a sliding support structure 2, an adjustment structure 3, and a control structure 4. The track frame structure 1 supports and guides the sliding support structure 2, facilitating handling and installation. The sliding support structure 2 bears and lifts the pipe 5. The track frame structure 1 utilizes multiple designs to provide multi-point support for key parts of the pipe 5. The adjustment structure 3, with its horizontal lateral movement structure 31 and lifting movement structure 32, allows for horizontal and vertical position adjustment of the pipe 5, effectively correcting positional deviations during docking. The control structure 4 enables rapid lifting and lowering of the lifting movement structure 32, further enhancing the ease of operation and construction safety during pipe 5 adjustment.

[0020] For details, please refer to the appendix. Figure 1 and attached Figure 2The track frame structure 1 includes two sets of tracks 11 arranged on both sides of the axial direction of the pipe 5 and track adjustment components 12 arranged on the tracks 11. The tracks 11 are linear guide rails, and can be made of lightweight aluminum alloy or high-strength alloy steel, depending on the weight of the pipe 5 to be supported. The tracks 11 can move on the support surface of the pre-dug pipe 5 trench. The lower end of the high-strength alloy steel track 11 can be equipped with pulleys for easy movement to improve on-site deployment efficiency. In this embodiment, the pipe 5 is a plastic drainage pipe. Two rails 11 are placed parallel to each other in a pre-dug pipe 5 groove, with the bottom of the rails 11 fitting against the bottom surface of the pipe 5 groove to form a stable support; the rail adjustment assembly 12 includes a threaded screw 121 and a rotating handle 122 disposed at the end of the threaded screw 121. The ends of both sets of rails 11 are provided with threaded holes 111 that are threadedly engaged with the threaded screw 121, so as to rotate the threaded screw 121 through the rotating handle 122 to realize the spacing adjustment function between the two rails 11, while improving the structural stability between the two sets of guide rails.

[0021] Please refer to the attached document. Figure 2 and attached Figure 3 The sliding lifting structure 2 is provided in at least three sets. Each set of sliding lifting structures 2 includes two sets of slides 24 respectively set on the corresponding rails 11 and a lifting support 25 set between the two sets of slides 24. The lifting support 25 includes an arc-shaped plate, which can be, but is not limited to, a rigid plate. The middle part of the arc-shaped plate is adapted to the shape of the lower side of the pipe 5 to achieve lifting constraint on the corresponding pipe 5. The two ends of the arc-shaped plate are rotatably connected to the slides 24 to adapt to the tilting scenario of the pipe 5. At least one set of sliding lifting structures 2 is engaged with the rear end of the front pipe 51, at least one set is engaged with the front end of the rear pipe 52, and at least one set is engaged with the rear end of the rear pipe 52. In this embodiment, the sliding lifting structure 2 is provided in three sets, respectively. The three sliding lifting structures 2, namely the first sliding lift 21, the second sliding lift 22, and the third sliding lift 23, are arranged sequentially along the length of the track 11. During docking, the first sliding lift 21 cooperates with the rear end of the front pipe 51, the second sliding lift 22 cooperates with the front end of the rear pipe 52, and the third sliding lift 23 cooperates with the rear end of the rear pipe 52. The position of the rear pipe 52 is adjusted by the adjusting device, and the rear end of the front pipe 51 is docked with the front end of the rear pipe 52. With the coordinated support of the three sliding lifting structures 2, the height and lateral position of each lifting support 25 can be adjusted by the adjusting structure 3 to ensure that the rear end of the front pipe 51 and the front end of the rear pipe 52 are precisely aligned, thus ensuring the stability of the docking process. Please refer to the attached document. Figure 3For pipes 5 using flange connections or other rigid connections, after docking, maintain the lifting constraint of the third sliding lift 23 on the rear end of the rear pipe 52, release the sliding constraints of the first sliding lift 21 and the second sliding lift 22 on the corresponding pipes 5, and move the first sliding lift 21 and the second sliding lift 22 below the rear end of the rear pipe 52. Re-establish the lifting constraint of the first sliding lift 21 on the rear end of the rear pipe 52. Releasing the lifting constraint on the pipe 5 is achieved by the lifting and moving structure 32 driving the lifting support 25 to descend. Re-establishing the lifting of the pipe 5 is achieved by the lifting and moving structure 32 driving the lifting support 25 to rise. After releasing the corresponding lifting constraints of the second sliding lift 22 and the third sliding lift 23, the track frame structure 1... The entire structure moves to the next pipe 5 hoisting position, i.e., backwards. The positions of the second sliding support 22 and the third sliding support 23 are moved so that the second sliding support 22 is below the front end of the next pipe 5 and the third sliding support 23 is below the rear end of the next pipe 5. Since the first sliding support 21 slides relative to the track 11 and is constrained by the pipe 5, it will not move arbitrarily when the track frame structure 1 is moved, and will still maintain the support constraint on the rear end of the pipe 5. If necessary, the first sliding support 21 can be fixed to the groove of the pipe 5 with a pin to ensure the stability of the pipe 5 during the movement of the track frame structure 1, and to avoid deformation of the connection part of the connected pipe 5 due to displacement. At the same time, it prepares the structure for the hoisting and docking of the next set of pipes 5.

[0022] Please continue to refer to the appendix. Figure 3For pipes 5 connected by a plug-in method, the connection is generally completed in the groove of pipe 5. After the connection is completed, the first sliding lift 21 is released from its support constraint on the rear end of the front pipe 51, separating it from the front pipe 51. After the pipes 5 are connected, the front end of the rear pipe 52 has formed a limiting constraint with the rear end of the front pipe 51, and the second sliding lift 22 continues to support the front end of the rear pipe 52. Therefore, the release of the constraint by the first sliding lift 21 will not affect the connection state of the two pipes 5. Subsequently, the first sliding lift 21 is moved to below the front end of the rear pipe 52 and forms a supporting constraint on the front end of the rear pipe 52. The three sets of sliding lift structures 2 descend synchronously, making the front pipe 51 and the rear pipe 52 closer to the ground. Then, the third sliding lift 23 rises. At this time, the lower side of the front pipe 51 is supported by the ground or a preset limiting bracket. The rear pipe 52 uses the connection point between the front pipe 51 and the rear pipe 52 as a fulcrum, so that the rear pipe 52 is in an inclined state, providing the operating space required to release the constraints of the first sliding lift 21 and the second sliding lift 22. The first sliding lift 21 and the second sliding lift 22 move backward along the track 11 and move to below the rear end of the rear pipe 52. The first sliding lift 21 rises through the lifting and moving structure 32 to lift and constrain the rear end of the rear pipe 52. The third sliding lift 23 releases the lifting constraint on the rear pipe 52 and moves the entire track frame structure 1 to the next pipe 5 hoisting position (i.e., the rear). The positions of the second sliding lift 22 and the third sliding lift 23 are moved so that the second sliding lift 22 is below the front end of the next pipe 5 and the third sliding lift 23 is below the rear end of the next pipe 5. This cycle is repeated to complete the continuous insertion and connection of the pipe 5 docking operations.

[0023] Please refer to the attached document. Figure 2 and attached Figure 4The adjustment structure 3 includes a horizontal sliding structure 31 and a lifting moving structure 32; this enables multi-directional adjustment of the pipe 5 in the horizontal and vertical directions, ensuring docking accuracy. The horizontal sliding structure 31 is slidably mounted on the slide table 24, and its sliding direction is perpendicular to the axial direction of the pipe 5. Specifically, the horizontal sliding structure 31 includes a sliding frame 311 and a locking assembly 312. The sliding frame 311 includes a sliding plate 3111 and a sliding limiting protrusion disposed on the lower side of the sliding plate 3111. The upper side of the slide table 24 is provided with a sliding groove 241 that cooperates with the sliding protrusion, so that the sliding limiting protrusion and the sliding groove 241 can be connected. The sliding frame 311 is restricted by the cooperation of the sliding plate 24 to ensure the horizontal movement direction. The sliding frame 311 is located on the side of the sliding table 24 near the lifting support 25. The locking assembly 312 is fixed on the side of the sliding table 24 away from the lifting support. The locking assembly 312 includes a locking screw 3121 and a screw seat 3122. The screw seat 3122 is fixed to the sliding table 24. The locking screw 3121 is located on the screw seat 3122 and its end abuts against the sliding plate 3111. By means of the abutting cooperation between the locking screw 3121 and the sliding plate 3111, the sliding frame 311 is rigidly locked after being adjusted to the position.

[0024] Please continue to refer to the appendix. Figure 2 and attached Figure 4 The lifting and moving structure 32 includes a lifting drive device 321 and a lifting assembly 33. The lifting drive device 321 is disposed on the horizontal transverse structure 31. The movable end of the lifting assembly 33 moves up and down on the horizontal transverse structure 31 via the lifting drive device 321. The lifting assembly 33 is provided with a fixed connection part. Specifically, the lifting assembly 33 includes a lifting frame 331, a lifting block 332, and a connecting rod 333. In this embodiment, the lifting frame 331 is a rectangular frame, and the lifting frame 331 is vertically disposed on the sliding... On the upper side of plate 3111, the lifting frame 331 has a vertically extending lifting groove 3311 inside. The lifting block 332 is slidably disposed in the lifting groove 3311. One end of the connecting rod 333 is fixedly connected to the end of the lifting block 332 near the lifting support member 25, and the other end extends out of the lifting frame 331 and is connected to one end of the lifting support member 25. The lifting frame 331 has a movable groove 3312 for the connecting rod 333 to move. The two ends of the lifting support member 25 are provided with rotating holes 251, and the lifting support member 25 is rotatably connected to the connecting rod 333 through the rotating holes 251. This provides stable support through the rectangular frame structure of the lifting frame 331, restricts the lifting path by the sliding cooperation between the lifting groove 3311 and the lifting block 332, and ensures the verticality of the lifting process. At the same time, the rotatable connection between the connecting rod 333 and the lifting support member 25 adapts to the angle change when the pipe 5 is tilted, ensuring the flexibility and stability of the lifting.

[0025] Please refer to the attached document. Figure 4 The lifting drive device 321 can be an electric telescopic rod 3211 or a hydraulic jack 3212. In this embodiment, the lifting drive device 321 uses an electric telescopic rod 3211. The fixed end of the electric telescopic rod 3211 is located at the upper end of the lifting frame 331. A fixing plate 3313 is provided above the sliding plate 3111 to fix the electric telescopic rod 3211. The movable end of the electric telescopic rod 3211 is connected to the upper end of the lifting block 332. The fixing plate 3313 is used to achieve a stable installation of the electric telescopic rod 3211. The telescopic movement of the electric telescopic rod 3211 drives the lifting block 332 to move up and down precisely along the lifting groove 3311, thereby driving the lifting support 25 to adjust its height.

[0026] Please refer to the attached document. Figure 1 The control structure 4 is located at the end of one of the tracks 11. The control structure 4 is electrically connected to the lifting and moving structure 32 to drive and control the lifting and moving structure 32 through electrical signal transmission. Specifically, the control structure 4 includes a power supply module and a control module connected by a circuit. The control module can be, but is not limited to, a single-chip microcontroller control board of model AT80C51 or a microcontroller of model STM32. The output terminals of the relays are respectively connected to the electric telescopic rods 3211 in the lifting and moving structure 32 by a circuit, so as to realize the adjustment of the extension and retraction of the electric telescopic rods 3211 in the three sets of lifting and moving structures 32 through the control structure 4, thereby adjusting the position parameters such as the height and pitch angle of the pipe 5 to be hoisted and the pipe 5 already connected.

[0027] Example 2 In Example 2, the same symbols are used for the same structures as in Example 1, and the same descriptions are omitted. Example 2 is an improvement on Example 1. Please refer to [link / reference needed]. Figure 5 ; The lifting drive device 321 can be a hydraulic jack 3212. The movable end of the hydraulic jack 3212 is provided with a wedge block 3314. The lifting frame 331 is located in the middle of the sliding plate 3111. The fixed end of the hydraulic jack 3212 is located at the end of the sliding plate 3111 away from the lifting support member 25. The lifting frame 331 is provided with an opening 3315 for the wedge block 3314 to extend into. The lower side of the lifting member is an inclined surface that cooperates with the wedge block 3314.

[0028] Using the strong driving force of the hydraulic jack 3212 and the cooperation of the wedge block 3314 and the inclined plane, the horizontal thrust is converted into vertical lift, so as to achieve stable lifting and precise height adjustment of the heavy-duty pipe 5 and ensure the reliability of lifting in heavy-load scenarios.

[0029] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
