Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline construction tooling, and relates to a quick installation tensioner for flexible pipe fittings. Background Art

[0002] A pipeline is a device connected by pipes, pipe fittings, valves, etc. for transporting gases, liquids, or fluids with solid particles. During pipeline laying operations, the butt joint between pipes and pipe fittings usually involves manually pulling the end of the receiving pipe or inserting pipe first to make the ends of the receiving pipe and inserting pipe approach each other, and then adjusting the coaxiality of the ends of the receiving pipe and inserting pipe. After inserting the inserting pipe into the receiving pipe, sealing welding is carried out. However, due to the generally large length and diameter of the pipes, the operation is time-consuming and laborious. Summary of the Invention

[0003] The purpose of the utility model is to provide a quick installation tensioner for flexible pipe fittings in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to improve the operation efficiency of the butt joint between pipe fittings and pipes.

[0004] The purpose of the utility model can be achieved by the following technical solutions:

[0005] A quick installation tensioner for flexible pipe fittings, characterized in that it includes two parallel support rods, two sliding seats respectively arranged on the two support rods, and a driving component for driving the sliding seats to move horizontally along the support rods. A clamp is fixedly connected between the two support rods and between the two sliding seats respectively. The clamp includes two connected semi-circular clamping rings. A snap hook is arranged on one of the clamping rings, and a buckle handle is hinged on the other clamping ring. A buckle ring is hinged on the buckle handle, and the buckle ring is sleeved on the snap hook so that the two semi-circular clamping rings are butted and locked, and the buckle ring can be separated from the snap hook by pulling the buckle handle.

[0006] During use, the user only needs to horizontally place the pipes and pipe fittings to be installed into the two clamps respectively, and make the ends of the pipes and pipe fittings face each other. Then the user pulls the buckle handles of the two clamps in turn to sleeved the buckle rings on the snap hooks so that the two semi-circular clamping rings are butted and locked, thereby fixing the pipes and pipe fittings respectively. Then, by shaking the push rod, the sliding seats are driven to move horizontally along the support rods. The pipes fixed on the sliding seats move synchronously with the sliding seats, while the pipe fittings fixed on the two support rods by the clamps remain stationary, so that the pipes are inserted into the socket of the flexible pipe fittings to complete the insertion. The operation is simple and convenient, thus improving the operation efficiency of the butt joint between pipe fittings and pipes.

[0007] In the above-mentioned quick-installation tensioner for flexible pipe fittings, the middle parts of the two snap rings located between the two sliding seats are respectively fixedly connected to the sliding seats on the same side, and the middle parts of the two snap rings located between the two support rods are respectively fixedly connected to the support rods on the same side. The lower ends of the two snap rings of the same clamp respectively have connecting ears, and a positioning screw is passed through between the two connecting ears. A locking nut for adjusting the connection tightness between the two connecting ears is threadedly connected to the positioning screw. Before use, the user separates the two snap rings of the clamp to an appropriate position according to the diameter of the pipe fitting to be installed, and adjusts the tightness of the clamp by rotating the locking nut on the positioning screw of the clamp, so as to better place the pipe and pipe fitting into the clamp, and enable the clamp to better position the pipe and pipe fitting after being locked. After completing this operation, when installing pipes and pipe fittings of the same size later, it is possible to avoid re-adjusting the tightness of the two clamps, thereby improving the operation efficiency of pipe fitting docking.

[0008] In the above-mentioned quick-installation tensioner for flexible pipe fittings, an installation seat is provided at the upper end of one of the snap rings of the same clamp, the snap hook is provided at the upper end of the other snap ring of the above-mentioned clamp, the hook part of the snap hook faces away from the installation seat, the buckle handle is hinged on the installation seat, the buckle ring is horizontally arranged, one end of the buckle ring is hinged on the buckle handle, and the other end of the buckle ring is clamped on the hook part of the snap hook. The above structure can improve the reliability after the clamp is locked, prevent the buckle ring from disengaging from the snap hook by itself, and enable the buckle ring to disengage from the snap hook only when the buckle handle is pulled.

[0009] In the above-mentioned quick-installation tensioner for flexible pipe fittings, the connecting ear is a flat plate vertically arranged. By setting the connecting ear as a vertically arranged flat plate and setting the upper end face of the snap ring as a vertically arranged plane, the two snap rings of the clamp can be better docked to lock the pipe and pipe fitting in the clamp.

[0010] In the above-mentioned quick-installation tensioner for flexible pipe fittings, the driving assembly includes a push-pull rod vertically arranged on the sliding seat and swingable along the length direction of the support rod. A rack is arranged on the upper side of the support rod, the sliding seat is sleeved on the support rod, a gear is further arranged at the lower end of the push-pull rod, a relief hole is opened on the upper side of the sliding seat, and the gear extends into the relief hole and meshes with the rack. By adopting the above structure, when the push-pull rod is shaken, the gear arranged at the lower end of the push-pull rod will rotate synchronously, so that the sliding seat moves horizontally along the support rod, which is labor-saving and convenient, thereby changing the distance between the two clamps and realizing the docking operation of the pipe and pipe fitting. In addition, the driving assembly can also adopt a cylinder. Specifically, a slider is arranged inside the sliding seat and is slidably sleeved on the support rod, and the output shaft of the cylinder is connected to the end of the sliding seat.

[0011] Compared with the prior art, the advantages of this quick-installation tensioner for flexible pipe fittings are as follows: This quick-installation tensioner for flexible pipe fittings can assist manual operation in inserting pipes and pipe fittings, with simple and convenient operation, thus improving the operation efficiency of butt-jointing pipe fittings and pipes.
