[0001] This utility model relates to the field of pipeline construction equipment technology, specifically to a pipeline guiding and docking device for water conservancy pipeline construction. Background Technology
[0002] In water conservancy pipeline construction sites, mechanical excavation of trenches and foundation pits is commonly used. After the trenches and foundation pits are completed, the pipelines to be laid are moved into the pipeline foundation pits. Pipeline connection is usually done manually, using tools such as crowbars to slowly move the pipelines to the connection position, which is time-consuming and labor-intensive. With the development of technology, mechanized pipeline connection equipment has been gradually applied to pipeline construction; however, most existing pipeline connection equipment is installed on a base and is suitable for compacted ground. For foundation pits formed by excavation, the movement conditions are still limited, especially for deep foundation pits. The equipment base cannot be placed in the uneven and geologically complex deep foundation pits, making it unusable. Summary of the Invention

Detailed Implementation
[0030] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.
[0031] Please refer to Figures 1-3This invention provides an embodiment of a pipeline guiding and docking device for water conservancy pipeline construction, comprising a positioning component, a clamping component, and a support component. The positioning and clamping components work together to directly fix the device onto an assembled pipeline. Simultaneously, the positioning component also positions and supports the pipeline to be connected until the pipeline docking operation is completed. The support component includes a fixed support 8, which can be welded and assembled from common materials such as steel plates and channel steel. The fixed support 8 is generally rectangular, and in use, its length corresponds to the axial direction of the pipeline. The clamping component includes a clamping block 11, which is mounted on the fixed support 8 and can be raised and lowered relative to the fixed support 8. The positioning component includes two positioning plates 1, both of which are inclined, forming a V-shaped positioning groove 12 between them.
[0032] like Figure 3 As shown, the method of using the pipe guiding and docking device of this application is illustrated by taking the docking operation of the first pipe 17 and the second pipe 18 as an example. The first pipe 17 has already been docked, with one end being a fixed end and the other a free end. The second pipe 18 is the pipe to be docked, with both ends being free ends. Two positioning plates 1 contact the outer wall of the free end of the first pipe 17, and together with the clamping block 11, achieve a fixed connection between the device and the first pipe 17. The portions of the two positioning plates 1 extending out of the first pipe 17 provide support and positioning for the second pipe 18. Using lifting equipment, the second pipe 18 is placed on the two positioning plates 1. Under the limitation of the two positioning plates 1, the first pipe 17 and the second pipe 18 are aligned. Axially pushing the second pipe 18 will dock it with the already fixed first pipe 17. Subsequently, welding or other methods can be used to fix the first pipe 17 and the second pipe 18 together.
[0033] As one connection method between the clamping block 11 and the fixed bracket 8, the fixed bracket 8 is equipped with a lifting mechanism 7, and the lifting shaft of the lifting mechanism 7 is fixedly connected to the clamping block 11. The lifting mechanism 7 can be a worm gear lifting mechanism, which allows for manual adjustment and simplifies the equipment structure, and also enables the pipe guiding and docking device to be used in environments without electricity. Preferably, the clamping block 11 is positioned directly above the positioning groove 12, and particularly centered in the width direction of the positioning groove 12.
[0034] The two positioning plates 1 of the positioning component are connected to the fixed bracket 8 through the adjustment bracket, so that the distance between the two positioning plates 1 is adjustable, that is, the width of the positioning groove 12 can be adjusted. This not only allows the pipe guiding docking device to be used in the docking operation of pipes with different outer diameters, but also allows the pipe guiding docking device to be removed from the pipe after the pipe docking is completed.
[0035] Each adjustment bracket includes a connecting plate 4 and several first brackets 2. The lower end of the first bracket 2 is fixedly connected to the positioning support plate 1, and the upper end is fixedly connected to the connecting plate 4. The fixed bracket 8 is provided with at least two guide shafts 5. Preferably, the two guide shafts 5 are fixed to both ends of the fixed bracket 8 along its length by connecting sleeves 6. The first brackets 2 or the connecting plate 4 are slidably connected to the guide shafts 5 by guide sleeves 9. For example, as shown... Figure 1 As shown, there are two first brackets 2, which are fixedly connected to both ends of the connecting plate 4 respectively; the guide sleeve 9 is fixed to the upper end of the first bracket 2, and the two adjusting brackets are slidably set at both ends of the guide shaft 5.
[0036] Each of the two connecting plates 4 is also equipped with a drive sleeve 3, which has a threaded hole that passes through both the drive sleeve 3 and the connecting plate 4. An adjusting screw 10 is located between the two connecting plates 4. The two ends of the adjusting screw 10 are threaded, with opposite directions of rotation, and both threads engage with the threads of the drive sleeve 3. Rotating the adjusting screw 10 causes the two drive sleeves 3 to move closer together or separate. An operating handwheel is fixed to one end of the adjusting screw 10. The operating handwheel and the operating lever of the elevator 7 are located on the same side of the fixed bracket 8 for easy operation.
[0037] Furthermore, the positioning tray 1 includes two parallel and spaced-apart support plates 14, with a plurality of rollers 13 disposed between the two support plates 14. The two ends of each roller 13 are rotatably mounted on the two support plates 14. Adjacent rollers 13 are spaced apart, particularly at the end of the first pipe 17, where the distance between the two rollers 13 is appropriately increased to provide sufficient operating space for subsequent welding and other operations. For example, an operating window 16 is provided in the middle of the positioning tray 1. In use, the free end of the first pipe 17 is aligned with the operating window 16, thus ensuring the pipe's mating position is directly opposite the operating window 16. The operating window 16 can be formed by removing one or two rollers 13.
[0038] Preferably, a plurality of reinforcing plates 15 are provided between the two supporting plates 14, and the two ends of the reinforcing plates 15 are respectively fixedly connected to the two supporting plates 14. The reinforcing plates 15 are spaced apart, and the positions of the reinforcing plates 15 correspond one-to-one with the rollers 13, located on the underside of the rollers 13 or in other positions that avoid the supporting surface of the rollers 13.
[0039] The clamping block 11 can be made of wear-resistant materials such as rubber with a certain amount of elastic deformation. Depending on the needs, especially the material of the pipe, a buffer sleeve can be fitted on the outside of the roller 13. The thickness of the buffer sleeve should not be too thick, as this will affect the accuracy of the pipe docking and positioning. The hardness of the buffer sleeve material should be slightly less than that of the pipe material.
[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
