[0033] This invention provides a convenient tool for installing large-diameter PCCPs, aiming to offer a more user-friendly and labor-saving solution. Existing tools for installing large-diameter PCCPs align and tighten the ends of two PCCP tubes using two square tubes, then pull the two PCCP tubes closer together using a tightening hinge. However, in this method, tightening the hinge requires a person to repeatedly operate a lever hoist on both sides, resulting in high workload for the operator. Furthermore, when installing the two square tubes, the lack of clear markings between the square tubes and the PCCP tubes necessitates manual confirmation of the tubes' placement by the operator, involving measurement, calculation, and angle adjustment, significantly reducing work efficiency. To address these issues, this invention provides a convenient tool for installing large-diameter PCCPs, as detailed below:

[0034] Example 1

[0035] Please see Figures 1 to 4 In this embodiment, a tool for conveniently installing a large-diameter PCCP is provided, which includes: two hollow square columns 1 arranged symmetrically, two lever hoists 5 arranged symmetrically, and two hinges 4 arranged symmetrically.

[0036] Please refer to Figure 2 ,Figure 2 This is a front view of the hollow square column 1 and metal sheet 2 structure. Each of the two hollow square columns 1 has a symmetrical connection point 3 on its first side, which is used for hinge connection with a hinge 4 or a lever hoist 5. Crucially, each of the two hollow square columns 1 has a symmetrical metal sheet 2 on its second side. The outer edge of the metal sheet 2 is arc-shaped, and its inner end is fixed to the end of the hollow square column 1. The perpendicular line from the midpoint of the outer edge of the metal sheet 2 is parallel to the axis of the hollow square column 1. Using the metal sheet 2, the hollow square column 1 can be easily and accurately aligned with the corresponding position of the outer edge of the PCCP pipe, effectively improving work efficiency.

[0037] In addition, please see Figure 1 and Figure 3 , Figure 3 This is a top view of the hollow square column 1 and metal sheet 2 structure. The fixed ends of two lever hoists 5 are connected to two connection points 3 of the same hollow square column 1. The non-fixed ends of the two lever hoists 5 are connected to two connection points 3 of another hollow square column 1 via hinges 4. In use, tightening the hinges 4 allows for the tightening and splicing of the two PCCP pipes. Furthermore, tightening the hinge on one side individually allows for fine-tuning of the pipe spacing, thereby improving installation accuracy. This device is simple to operate, easy to install and dismantle, low in cost, convenient and flexible in use, and has a wide range of applications. The self-made internal pulling device can be used in conjunction with large crawler cranes, reducing labor intensity and shortening the construction cycle. This tool can improve pipeline installation accuracy and ensure the quality of PCCP pipeline installation. The fixed end refers to the end without hinge extension, and the non-fixed end refers to the extendable hinge.

[0038] This invention makes the hollow square column 1 more intuitive to use by setting a metal sheet 2 on the side. Since the shape and curvature of the metal sheet 2 are similar to the curvature of the PCCP pipe, the operator can see with his eyes where the metal sheet 2 should be placed on the outer edge of the PCCP pipe, which effectively improves the placement efficiency and accuracy and increases the working power.

[0039] Example 2

[0040] Please see Figures 5 to 7 Based on Embodiment 1, the tool for conveniently installing large-diameter PCCPs also includes a combined drive box 6, which comprises an I-shaped box plate 61, a fixing component 62, a straight plate 64, a gear 65, a rack 66, a connecting rope 67, and a drive component 68. The metal sheet 2 can also be replaced with a high-fiber polyester plastic sheet.

[0041] Please refer to Figure 5 and Figure 6Two fixing components 62 are symmetrically arranged at the bottom of the I-shaped box plate 61. The fixing components 62 are used to fix the two lever hoists 5. A straight plate 64 is fixed to the upper part of the I-shaped box plate 61. A gear 65 is rotatably mounted on the straight plate 64. Two racks 66 are symmetrically and slidably connected to the straight plate 64. The racks 66 are slidably connected to the straight plate 64. The two racks 66 are respectively connected to the two lever hoists 5 through connecting ropes 67. The connecting ropes 67 can be formed by interlacing and twisting multiple strands of steel rope. A drive component 68 is set on the gear 65. The drive component 68 is used to drive the gear 65 to rotate. In this embodiment, the drive component 68 includes a disc 681 and a shaft 682. The shaft 682 is fixed to the shaft end of the gear 65, and the disc 681 is fixed to the other shaft end of the shaft 682. By rotating the disc 681, the left and right lever hoists 5 can be operated simultaneously, which can effectively reduce the labor intensity of the operator in the early PCCP tensioning operation.

[0042] In this embodiment, connection point 3 is a collar, and the fixed or non-fixed end of the lever hoist 5 is connected to the collar. In other embodiments, connection point 3 may not be directly connected to the hollow square column 1. Instead, a rotating sleeve 7 is rotatably fitted onto the hollow square column 1, with connection point 3 fixed to the outer wall of the rotating sleeve 7. Connection point 3 is connected to the fixed or non-fixed end of the lever hoist 5. The advantage of this is that, since the rotating sleeve 7 is rotatable relative to the hollow square column 1, after installing one PCCP pipe, it is not necessary to reinstall and pair the original two hollow square columns 1. Only the inner hollow square column 1 needs to be removed, and then the rotating sleeve 7 can be used to transform the original outer hollow square column 1 into the inner hollow square column 1 for the next step. This saves the next step of pipe installation, effectively improving work efficiency and reducing labor intensity.

[0043] Please see Figure 5 Two hooks 69 are symmetrically fixed at the ends of the straight plate 64. The ends of the two connecting ropes 67 are detachably connected to the two lever hoists 5. The two hooks 69 are used to hook the ends of the two connecting ropes 67 after they are separated.

[0044] In addition, the combined drive box 6 also includes a double-hole plate 63. The double-hole plate 63 is fixed in the middle of the I-shaped box plate 61, and the two connecting ropes 67 pass through the two holes of the double-hole plate 63 respectively. The double-hole plate 63 can limit the two connecting ropes 67, thereby ensuring that the force applied by the two connecting ropes 67 to the wrench of the lever hoist 5 is within a reasonable range.

[0045] Please see Figure 6The fixing assembly 62 includes a fixing plate 621, a movable plate 622, a limiting groove 623, and a threaded rod assembly 624. The fixing plate 621 is fixed to the middle of the inner bottom of the I-shaped box plate 61. The inner bottom of the I-shaped box plate 61 has a limiting groove 623, which is slidably connected to the upper limit of the limiting groove 623. The movable plate 622 is located on one side of the inner bottom of the I-shaped box plate 61. The threaded rod assembly 624 includes a fixing block and a threaded rod. The fixing block is fixed to the side of the I-shaped box plate 61, and the threaded rod is threadedly connected to the fixing block. One end of the threaded rod is rotatably connected to the movable plate 622. The fixing plate 621 and the movable plate 622 are used to clamp the lever hoist 5. This detachable installation structure can not only drive two lever hoists 5 simultaneously, but also allow for individual fine-tuning of either of the two lever hoists 5 at any time. Since the two racks 66 are connected to the two lever hoists 5 respectively via connecting ropes 67, there is a movable margin between the lever hoists 5 and the disc 681. The key point is that after the PCCP pipeline is roughly moved to the approximate position, it can also be fine-tuned by turning either of the lever hoists 5 on both sides. This reduces the labor intensity of the operator while maintaining the accuracy of construction.

[0046] Please see Figure 7 A clamp is provided on one side of the metal sheet 2 to hold the metal sheet 2 against the outer edge of the PCCP pipe. The clamp consists of symmetrically arranged clamping pieces. Alternatively, by providing a clamp on one side of the metal sheet 2 and clamping the outer edge of the PCCP pipe, the positions of the metal sheet 2 and the hollow square column 1 are defined. Since the clamping position on the PCCP pipe is fixed, once clamping is complete, the installation positions of the metal sheet 2 and the hollow square column 1 are guaranteed to be accurate, thus saving inspection steps during installation and effectively improving construction efficiency.

[0047] By installing the lever hoist 5 inside the combined drive box 6, when the lever hoist 5 needs to be used, simply rotating the disc 681 will allow both lever hoists 5 to rotate simultaneously. During use, the operator does not need to operate one side of the lever hoist 5 individually, effectively reducing the operator's workload. After roughly moving the PCCP pipeline to its approximate position, fine adjustments can also be made by operating either of the two lever hoists 5 separately, thus maintaining accuracy during construction while reducing the operator's labor intensity.
