Description

Technical Field

[0001] This utility model relates to the field of puller devices, and more particularly to a puller device for disassembling quick couplings. Background Technology

[0002] Many modern industrial enterprises have process hoses on their equipment that require frequent disassembly. These are typically connected using quick-connect couplings. To connect a quick-connect coupling, the outer steel ring on the female connector is pulled outwards and then inserted into the male connector. The outer ring on the female connector is then released, locking the male connector in place. To disconnect, the outer ring on the female connector is pulled outwards, allowing it to separate from the male connector. Normally, new quick-connect couplings insert and remove smoothly. However, if the quick-connect coupling has not been disassembled for a long time, or if the pipeline carries fluids prone to scaling (such as lime slurry, salty water, or water with many impurities), the quick-connect coupling may become stuck and unable to separate smoothly. In emergencies, the quick-connect coupling may have to be destructively removed by cutting, which is both time-consuming and wasteful of materials.

[0003] For example, in waste incineration power plants, rotary deacidification atomizers may malfunction for various reasons, or require periodic replacement of the backup atomizer according to safety regulations. To prevent the emission of acidic gases in the flue gas from exceeding standards due to the loss of the atomizer's deacidification function, the replacement time of the atomizer should be shortened as much as possible. In this case, due to the aforementioned situations, disassembling the quick connector located on top of the atomizer is usually not smooth, which takes a lot of time and poses environmental risks.

[0004] Existing puller devices require the screw to be pressed against the shaft, but when it comes to disassembling quick couplings, the quick couplings are usually connected to a hose at the back, leaving the screw with nowhere to bear force, thus rendering them unusable. Utility Model Content

[0005] To address the problem of difficult disassembly of quick couplings in existing technologies, this invention provides a puller device capable of quickly disassembling quick couplings.

[0006] This utility model provides a puller device for disassembling quick couplings, including a puller support, a pull claw, and a lifting screw. The puller support includes a bottom support ring with an opening, an upper support plate, and a support connecting rod connecting the upper support plate and the bottom support ring. The upper support plate has a threaded hole at its center that is adapted to the lifting screw. The pull claw includes a pull claw disc and multiple grippers hinged to the lower end of the pull claw disc. The lower end of the lifting screw passes through the threaded hole and is connected to the center of the pull claw disc, and can rotate freely.

[0007] As a further improvement of this utility model, a wrench connector is fixedly provided at the upper end of the lifting screw.

[0008] As a further improvement of this utility model, the wrench connector is a hexagonal nut.

[0009] As a further improvement of this utility model, the supporting connecting rods are multiple.

[0010] As a further improvement of this utility model, the gripper has two or three claws.

[0011] As a further improvement of this utility model, the upper support plate has a circular structure.

[0012] As a further improvement of this utility model, the pull claw disc has a circular structure and its diameter is smaller than that of the upper support plate.

[0013] As a further improvement of this utility model, a silicone anti-slip pad is provided at the lower end of the bottom support ring.

[0014] The beneficial effects of this utility model are: by setting a bottom support ring with an opening, this utility model can be directly fitted onto this quick connector with a connecting tube, thereby enabling the quick connector female head to be pulled out, which greatly facilitates the disassembly of quick connectors that are rusted or stuck.

[0017] In the description of this utility model, it should be understood that if there are descriptions involving orientation, such as up, down, front, back, left, right, etc., indicating orientation or positional relationship, the orientation description may be based on the orientation or positional relationship shown in the accompanying drawings. This is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0018] In the description of this utility model, if there is a description of quantity, "several" means one or more, "more than" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the number itself, while "above," "below," "within," etc. are understood to include the number itself. If there is a description of "first" or "second," it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] like Figure 1 As shown, this utility model discloses a puller device for disassembling quick connectors, including a puller support, a pull claw, and a lifting screw 6. The puller support includes a bottom support ring 1 with an opening 8, an upper support plate 2, and a support connecting rod 3 connecting the upper support plate 2 and the bottom support ring 1. The upper support plate 2 has a threaded hole at its center that is adapted to the lifting screw 6. The pull claw includes a pull claw disc 4 and multiple grippers 5 hinged to the lower end of the pull claw disc 4. The lower end of the lifting screw 6 passes through the threaded hole and is connected to the center of the pull claw disc 4 and can rotate freely.

[0021] In use, insert the puller device through the opening 8 of the bottom support ring 1 onto the outside of the connector to be disassembled, and then support the bottom support ring 1 on the outside of the quick connector. Then rotate the lifting screw 6 to adjust the height of the pull claw so that the claw 5 of the pull claw engages with the lower edge of the steel sleeve on the female head of the quick connector. At this time, continue to rotate the lifting screw 6 to pull up the steel sleeve on the female head, and then the female head and male head of the quick connector can be separated to achieve the purpose of quickly separating the quick connector.

[0022] This invention features a bottom support ring 1 with an opening 8, which allows it to be directly fitted onto a quick connector with a connecting tube, thereby enabling the quick connector female to be pulled out, greatly facilitating the disassembly of quick connectors that are rusted or stuck.

[0023] In this utility model, a wrench connector 7 is fixedly provided at the upper end of the lifting screw 6. The wrench connector 7 is a hexagonal nut. The lifting screw 6 can be rotated by a manual wrench or an electric wrench, which saves effort and reduces the workload of the operator.

[0024] In this invention, there are multiple supporting rods 3 to ensure the connection strength between the upper support plate 2 and the bottom support ring 1.

[0025] In this invention, the grippers 5 are either two or three, both capable of pulling. The grippers 5 are hinged to the puller disc 4 via pins or hinges.

[0026] In this invention, the upper support plate 2 is circular, and the pull claw disc 4 is also circular with a diameter smaller than that of the upper support plate 2. This design saves space, facilitates storage, and eliminates sharp corners, making it safer.

[0027] In this utility model, the lower end of the bottom support ring 1 is provided with a silicone anti-slip pad, which plays an anti-slip role and can also prevent scratches on the contact surface.

[0028] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
