Description

Technical Field

[0001] This utility model relates to the field of pipeline installation equipment technology, specifically to a composite pipe joint installation device. Background Technology

[0002] Composite pipes are multi-layered pipes made from two or more layers of different materials through a composite process. Due to the superior properties of each layer, they are widely used in municipal engineering, chemical industry, water conservancy, and gas transmission. Pipe fittings, as key components connecting two composite pipes, directly affect the sealing and safety of the pipeline system. However, the locking components in existing pipe fitting installers are typically fixed to a frame with a fixed inner wall curvature, only suitable for a single specification of composite pipe. Since composite pipes come in various diameters in actual projects, replacing them with different diameter pipes requires replacing the entire locking clamp, increasing equipment procurement costs and leading to low installation efficiency due to frequent disassembly. Summary of the Invention

[0003] The technical problem to be solved by this utility model is how to overcome the deficiency of the limited adaptability of pipe locking clamps in the prior art for pipe joint installers.

[0004] The technical solution adopted by this utility model is: a composite pipe connector installation device, including a fixing ring and a locking ring assembly. The locking ring assembly includes an upper locking ring and a lower locking ring. The interiors of the upper locking ring and the lower locking ring are hollow. Both the upper locking ring and the lower locking ring are connected to the fixing ring through a connecting rod. A sliding rod is provided at the end of the fixing ring away from the connecting rod. The sliding rod is connected to a pushing ring. The lower locking ring is provided with a first circular through hole assembly. The diameters of the circular through holes provided on the inner and outer walls of the lower locking ring are not the same. An adjusting rod is slidably connected to the first circular through hole assembly. The adjusting rod is located on one side of the lower locking ring and is connected to a first lower abutting arc plate. An elastic element is sleeved on the adjusting rod. One end of the elastic element abuts against the first lower abutting arc plate, and the other end of the elastic element abuts against the first lower abutting arc plate.

[0005] The above structure has the following beneficial effects: (1) By setting a fixed ring, a locking ring group including an upper locking ring and a lower locking ring, and using a connecting rod to achieve a stable connection between the upper and lower locking rings and the fixed ring, the rigidity of the overall structure is guaranteed; the sliding rod on the fixed ring cooperates with the pushing ring to provide a stable sliding guide for the docking of the pipe joint and the composite pipe, making the moving direction of the pushing ring more accurate and facilitating precise pushing docking.

[0006] (2) The first circular through hole group of the lower locking ring adopts a design with different diameters of the inner and outer circular through holes, and an elastic element is sleeved on the adjusting rod so that one end of the elastic element can abut against the first lower abutting arc plate, and the other end of the elastic element abuts against the lower locking ring. While providing elastic pre-tightening force, the elastic element can also adapt to composite pipes with different pipe diameters.

[0007] Preferably, the lower locking ring is further provided with an adjustment through hole. There are two sets of adjustment through holes, which are respectively located on both sides of the first lower abutment arc plate. An arc-shaped slider is slidably connected inside the lower locking ring at the position of the adjustment through hole. The arc-shaped slider is provided with a through hole and the through hole is connected to an adjustment rod. The adjustment rod includes a rotating part and a rotating rod. The rotating part is provided with a rotating groove, and the rotating rod is provided with a rotating boss. The rotating groove and the rotating boss are rotatably connected. The rotating part is rotatably connected to the second lower abutment arc plate on one side of the inner wall of the lower locking ring. The rotating rod is connected to the inner wall of the through hole on the arc-shaped slider. An adjustment knob is threadedly connected to the side of the adjustment rod located on the outer wall of the lower locking ring.

[0008] Two sets of adjustment through holes, in conjunction with an arc-shaped slider, allow for more flexible adjustment of the position of the second lower abutment arc plate, accommodating composite pipes of different diameters. Through the cooperation of the arc-shaped slider and the adjustment rod, as the rotating rod in the adjustment rod rotates continuously, the position of the second lower abutment arc plate also moves. Once adjusted to the appropriate position, it is locked by the adjustment knob, thereby achieving multi-directional clamping and fixing of the composite pipe, further improving the stability of the composite pipe during installation and preventing it from shaking.

[0009] Preferably, the upper locking ring is provided with a second circular through hole group, the second circular through hole group is slidably connected to another adjusting rod, the other adjusting rod is rotatably connected to an upper abutting arc plate on one side of the inner wall of the upper locking ring, the other adjusting rod is threadedly connected to another adjusting knob on one side of the outer wall of the upper locking ring, and the other adjusting rod is rotatably connected to an upper abutting arc plate on one side of the inner wall of the upper locking ring.

[0010] The second circular through hole assembly of the upper locking ring, together with the adjusting rod, adjusting knob, and upper abutment arc plate, forms an upper locking structure corresponding to the lower locking ring. The operator can adjust the position of the upper abutment arc plate by adjusting the knob, so that the upper abutment arc plate fits against the upper wall of the composite pipe, and cooperates with the first and second lower abutment arc plates on the lower side to form an upper and lower clamping, thereby achieving circumferential stable fixation of the composite pipe, adapting to the installation requirements of composite pipes of different diameters, and improving the versatility of the device.

[0011] Preferably, the fixed ring is provided with a first rotating shaft, the first rotating shaft is rotatably connected to a pusher, the top end of the pusher is provided with a second rotating shaft, the push ring is provided with a third rotating shaft, and a connecting rod is connected between the second rotating shaft and the third rotating shaft, with the two ends of the connecting rod respectively rotatably connected to the second rotating shaft and the third rotating shaft.

[0012] Through the linkage structure formed by the first rotating shaft, the pusher, the second rotating shaft, the third rotating shaft and the connecting rod, the rotation of the pusher is converted into the linear sliding of the push ring along the sliding rod. The operator only needs to rotate the pusher to drive the push ring to push the pipe joint, which can effectively improve the docking efficiency and accuracy of the pipe joint and the composite pipe.

[0013] Preferably, a limiting plate is provided at the end of the adjusting rod away from the first lower abutting arc plate.

[0014] The limiting plate at the end of the adjusting rod can effectively limit the sliding stroke of the adjusting rod, prevent the adjusting rod from falling out of the first circular through hole group, ensure the connection stability between the adjusting rod and the lower locking ring, avoid the interruption of pipe joint installation or structural failure due to component detachment, and further improve the reliability of the device.

[0015] Preferably, the top surface of the pusher is provided with a push rod.

[0016] The push rod on the top surface of the pusher provides a convenient point of force application for the operator, making it easy for the operator to drive the pusher to rotate by pushing or pulling the push rod, reducing the difficulty of operation and making the sliding adjustment of the push ring more effortless and convenient.

[0017] Preferably, a limit nut is connected to the side of the sliding rod away from the fixed ring.

[0018] The limiting nut at the end of the sliding rod can limit the maximum sliding distance of the push ring along the sliding rod, preventing the push ring from falling off the sliding rod due to excessive sliding, ensuring the stability of the fit between the push ring and the sliding rod, avoiding the loss or damage of parts, and also providing a clear stroke boundary for the sliding of the push ring.

[0019] Preferably, a locking ring is connected to the end of the pushing ring away from the fixed ring.

[0020] The locking ring connected to the end of the push ring can directly abut against the pipe joint. By rotating the locking ring, the locking ring can be tightly abutted against the pipe joint. At the same time, the locking ring can be replaced according to the joint specifications, improving the device's adaptability to different types of pipe joints.

[0021] Preferably, the locking ring is provided with a rotating protrusion that facilitates rotation.

[0022] The rotating protrusion on the locking ring provides a non-slip force application point for workers to rotate the locking ring, which facilitates quick installation or removal of the locking ring, reduces the difficulty of changing locking rings of different specifications, improves the maintenance and adjustment efficiency of the device, and enhances ease of use.
