Description

Technical Field

[0001] The utility model relates to the technical field of installation tools, in particular to a quick installation tool for large-diameter ductile iron pipes. Background Art

[0002] Ductile iron pipe refers to a pipe made by high-speed centrifugal casting in a centrifugal ductile iron machine after adding spheroidizing agent to molten iron above No. 18. It is referred to as ductile iron pipe, ductile iron pipe and ductile iron pipe for short. It is mainly used for the transportation of tap water and is an ideal material for tap water pipes. Quick installation tools will be required during its installation.

[0003] The existing ductile iron pipe quick installation tool is not convenient for multiple people to hold and use at the same time in actual use. Since large-diameter ductile iron pipes are heavy, relying on the strength of one person during installation will result in time-consuming and labor-intensive installation, and there will be problems with insufficient installation tightness.

[0004] For this reason, we propose a quick installation tool for large-diameter ductile iron pipes. Utility Model Content

[0005] In view of the deficiencies of the prior art, the utility model provides a quick installation tool for large-diameter ductile iron pipes, which overcomes the deficiencies of the prior art and aims to solve the problems in the background technology.

[0008] By adopting the above technical solution, the four bites can be clamped to the outer positions of the four positions of the ductile iron pipe, and then the pad can be pushed to drive the device and the ductile iron pipe to move, thereby realizing installation. At the same time, the anti-slip pad can increase the friction between the bite and the ductile iron pipe to ensure that it will not loosen easily.

[0009] As a preferred technical solution of the utility model, a round hole is opened on the top of the square rod, and the round hole corresponds to one position of the plurality of threaded holes, and the bolt is threadedly connected to the threaded hole and the inner wall position of the round hole.

[0010] By adopting the above technical solution, the bolts can be tightened to the inner wall positions of the threaded holes at different positions, thereby adjusting the length of the long rod exposed to the outside, thereby facilitating the adjustment of the position of the bite.

[0011] As a preferred technical solution of the utility model, a through hole is opened on the top of the protective cover, and the through hole passes through the protective cover and the fixed plate to the inner wall position of the power-assisting rod, the insertion rod is slidably connected to the inner wall position of the through hole, and a disc is fixedly installed on the top of the insertion rod.

[0012] By adopting the above technical solution, the power-assisting rod can be stably positioned in the middle position between the fixing plate one and the fixing plate two using the insertion rod to ensure that it will not be easily dislocated. The provided disc increases the convenience for the staff to manually pull the insertion rod, thereby facilitating moving the bottom end of the insertion rod out of the inner wall position of the power-assisting rod.

[0013] As a preferred technical solution of the utility model, the side of the power-assisting rod away from the rotating block is arranged in the middle position of the fixed plate 1 and the fixed plate 2, the number of the power-assisting rods is two, and the two power-assisting rods are symmetrically arranged on both sides of the square rod.

[0014] By adopting the above technical solution, the fixing plate one and the fixing plate two can be used to position the power-assisting rod, ensuring that it can be stably set in the middle position between the fixing plate one and the fixing plate two, ensuring that it will not be easily detached, and when the device needs to be used, the two power-assisting rods can be unfolded to form a cross shape with the square rod, so that two staff members can work together to pull and push to rotate the device.

[0015] As a preferred technical solution of the utility model, the spring is arranged at a middle position between gasket 1 and gasket 2, and the spring, gasket 1 and gasket 2 are all arranged in the inner cavity of the protective cover.

[0016] By adopting the above technical solution, gasket one and gasket two can be used to position the two ends of the spring, ensuring that the two ends will not rub against the inner wall of the protective cover, thereby preventing the user from directly pulling the insertion rod out.

[0017] Beneficial effects of the utility model:

[0018] 1. The insertion rod is driven to move by pulling the disc, so that the bottom end of the insertion rod can be moved out of the inner wall position of the power-assisting rod, so that the ends of the two power-assisting rods away from the rotating block can be pulled out from the middle position of the fixed plate 1 and the fixed plate 2, so that the staff can rotate the two power-assisting rods to drive the device and the ductile iron pipe to rotate, thereby realizing the installation, which makes it convenient for multiple people to hold hands and force together to rotate, avoiding the time-consuming and labor-intensive installation caused by insufficient strength of a single person, and the problem of insufficient installation tightness, and the power-assisting rods can be folded and stored when not in use to reduce space occupancy.

[0019] 2. By tightening the bolts to the inner wall positions of the threaded holes at different positions, the length of the long rod exposed to the outside can be adjusted, thereby facilitating the adjustment of the position of the bite, thereby facilitating the adjustment of the device for use according to different terrains, thereby improving applicability.
