Specific embodiments

[0025] To make the objectives, method solutions and advantages of the embodiments of the present utility model clearer, the method solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Usually, the components of the embodiments of the present utility model described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0026] Embodiment 1

[0027] Such as Figure 1As shown in the figure, a pipeline pigging device includes a main shaft 1 and a leather cup 2. The leather cup 2 is inserted through and fixed to the main shaft 1, and includes: a support member 3, one end of the support member 3 is connected to the inner side wall of the leather cup 2; an elastic member 4, the other end of the support member 3 is connected to the elastic member 4; when the side wall of the leather cup 2 is squeezed, the elastic member 4 contracts, and the resilience of the elastic member 4 is transmitted to the support member 3 through the support member 3.

[0028] In the specific implementation process, the material of the leather cup 2 can be a polyurethane body, which has excellent wear resistance and is suitable for long-distance pipeline cleaning. The support member 3 can be a rod body, and the support part is located at the edge of the leather cup 2. The elastic member 4 can be a spring. During use, the deformation characteristics of the leather cup 2 enable it to be suitable for pipelines with different diameters and some pipelines with variable diameters. During the mutual extrusion process between the leather cup 2 and the inner wall of the pipeline, the elastic member 4 can enhance the extrusion process, avoiding poor cleaning effect on the pipe wall relying solely on the material characteristics of the leather cup 2. At the same time, the presence of the elastic member 4 can strengthen the ability of the leather cup 2 to recover from deformation, avoiding slow or difficult recovery of its deformation, which affects the subsequent pipeline cleaning effect. Preferably, when the leather cup 2 is in a natural state, the elastic member 4 is in a natural state.

[0029] Embodiment 2

[0030] In order to prevent the support member 3 and the elastic member 4 from moving laterally when being squeezed and to limit the moving position of the support member 3, an improvement is made on the basis of Embodiment 1, as Figure 2 shown in the figure. In this embodiment, a slider 31 is provided on the side wall of the support member 3. This pigging device further includes: a connecting cylinder 5, a slide rail 51 matching with the slider 31 is provided on the inner wall of the connecting cylinder 5, the support member 3 is slidably connected to the connecting cylinder 5, and the elastic member 4 is arranged inside the connecting cylinder 5 and connected to the bottom end of the support member 3.

[0031] In the specific implementation process, through the limitation of the inner hole of the connecting cylinder 5, the elastic member 4 can be prevented from bending when being compressed. The setting of the slide rail 51 and the slider 31 can also avoid lateral movement between the support member 3 and the inner hole of the connecting cylinder 5, avoiding the obstruction of the inner hole of the connecting cylinder 5 to the movement of the support member 3. At the same time, by reasonably setting the starting point and the ending point of the slide rail 51, the longitudinal movement of the support member 3 can also be restricted. The connecting cylinder 5 can be connected to the main shaft 1 by screws.

[0032] Embodiment 3

[0033] In order to adjust the acting force of the elastic member 4 on the leather cup 2, an improvement is made on the basis of Embodiment 2. In this embodiment, it includes: a height adjustment mechanism, the bottom end of the spring is connected to the height adjustment mechanism, and the height adjustment mechanism is used to adjust the distance between the bottom end of the spring and the main shaft 1.

[0034] In the specific implementation process, after adjusting the height of the elastic member 4 through the height adjustment mechanism, under the same state of the leather cup 2, the reverse force of the elastic member 4 on the leather cup 2 is different, and the maximum outer diameter of the leather cup 2 is also different in the natural state of the device. For example, after increasing the distance between the bottom end of the elastic member 4 and the main shaft 1 through the height adjustment mechanism, the reverse acting force of the elastic member 4 on the leather cup 2 is greater, and the cleaning force is greater. At the same time, the outer edge of the leather cup 2 will also have a certain outward extension due to the resilience of the elastic member 4. There can be many structures of the height adjustment mechanism, and now two specific examples are listed, as shown in Embodiment 4-5.

[0035] Embodiment 4

[0036] In this embodiment, the height adjustment mechanism is an automatic telescopic rod.

[0037] In the specific implementation process, the telescopic length of the automatic telescopic rod can be controlled by an existing control system, such as a single-chip microcomputer. When the pipe cleaning device is stuck in the pipeline, the maximum outer diameter of the leather cup 2 can also be reduced by the contraction of the automatic telescopic rod to facilitate the smooth recovery of the leather cup 2.

[0038] Embodiment 5

[0039] As Figure 2-3 shown, in this embodiment, the height adjustment mechanism includes: a threaded rod 61, the bottom end of the threaded rod 61 is rotatably connected to the inner bottom wall of the connecting cylinder 5; a lifting member 62, the lifting member 62 is threadedly connected to the threaded rod 61, and the bottom end of the spring is connected to the lifting member 62; a guide rod 63, the lifting member 62 is disposed through the guide rod 63.

[0040] In the specific implementation process, the rotation of the threaded rod 61 can be driven by a motor, and the start and stop of the motor can also be controlled by an existing control system. The lifting member 62 can be a nut, and the spring is connected to the nut by welding. The guide rod 63 can be connected to the inner bottom wall of the connecting cylinder 5.

[0041] During operation, by rotating the threaded rod 61, the lifting member 62 is driven to move up and down along the guide rod 63, thereby realizing the change of the position of the bottom end of the spring.

[0042] Embodiment 6

[0043] As Figure 2-3 shown, in this embodiment, it includes: a first bevel gear 64, the first bevel gear 64 is coaxially connected to the threaded rod 61; a second bevel gear 65, the second bevel gear 65 meshes with the second bevel gear 65; a rotating rod 66, one end of the rotating rod 66 is coaxially connected to the second bevel gear 65, and the other end of the rotating rod 66 passes through the side wall of the connecting cylinder 5.

[0044] In the specific implementation process, the spring height can be adjusted automatically or manually. Although manual adjustment is relatively troublesome to operate, it has a lower production cost and can be selected according to needs. Figure 2 As shown, when the rotating rod 66 is turned, the second bevel gear 65 drives the first bevel gear 64 to rotate, and the first bevel gear 64 drives the threaded rod 61 to rotate, thereby realizing the position movement of the bottom end of the elastic member 4.

[0045] Example 7

[0046] In order to limit the moving position of the lifting member 62, improvements are made on the basis of embodiment 6, such as Figure 3-4 As shown, in this embodiment, it includes: a cross bar 67, there are two cross bars 67, and each end of the guide rod 63 is connected to one cross bar 67, and the guide rod 63 is connected to the inner wall of the connecting tube 5 through the cross bars 67.

[0047] In the specific implementation process, the guide rod 63 can be directly Figure 4 As shown, it is connected to the inner bottom wall of the connecting tube 5, but when the threaded rod 61 rotates, the lifting member 62 may be separated from the threaded rod 61 upwards, and may also move downwards and collide with the first bevel gear 64 or the second bevel gear 65, which is more likely to happen during manual adjustment. Therefore, two cross bars 67 are provided in this embodiment, and the cross bars 67 fix the guide rod 63 to the inner side wall of the connecting tube 5, and can also limit the distance of the lifting member 62 moving up and down to avoid the above situation. The connecting tube 5 can also be made of a transparent material to facilitate the observation of the position of the lifting member 62 during manual adjustment.

[0048] Example 8

[0049] In order to avoid the replacement of the support member 3, etc., improvements are made on the basis of embodiments 1-7, such as Figure 5 As shown, in this embodiment, a threaded tube 7 is embedded in the inner wall of the leather cup 2, and the support member 3 includes: a threaded segment 32, and one end of the threaded segment 32 away from the main shaft 1 is threadedly connected to the threaded tube 7; a fixed tube 33, and one end of the threaded segment 32 away from the threaded tube 7 is rotatably connected to the fixed tube 33, and one end of the fixed tube 33 away from the threaded tube 7 is connected to the elastic member 4.

[0050] During the specific implementation, if the elastic member 4, the height adjustment structure or the support member 3 is damaged or the elastic member 4 is elastically fatigued, in order to better achieve replacement, the support rod is provided with a threaded section 32 and a fixed cylinder 33 in this embodiment, and the threaded section 32 is inserted into the fixed cylinder 33 and is rotatably connected with the fixed cylinder 33. When disassembly is required, the threaded section 32 is rotated to disengage the threaded cylinder 7. The connecting cylinder 5 is connected to the main shaft 1 by screws and can also be easily disassembled.

[0051] Example 9

[0052] As Figure 1 shown, in this embodiment, video probes 8 are provided at both ends of the main shaft 1.

[0053] During the specific implementation process, the video probe 8 can master the situation inside the pipe through real-time photography. For example, when the pigging device gets stuck in the pipe, the outer diameter of the leather cup 2 can be adjusted through the cooperation of the video probe 8 and the height adjustment mechanism, and at the same time, it can be confirmed whether the stuck state of the leather cup 2 is smoothly released.

[0054] Embodiment 10

[0055] As Figure 6 shown, a pigging assembly includes: a pipeline pigging device; a launching cylinder 9, the pipeline pigging device is placed in the launching cylinder 9, and the launching cylinder 9 can be communicated with the starting end of the pipeline cleaning; an air compressor 10, the air compressor 10 is connected to the launching cylinder 9; a receiving cylinder 11, the receiving cylinder 11 can be communicated with the end point of the pipeline cleaning; the air compressor 10 drives the pipeline pigging device through compressed air. After entering the pipeline to be cleaned from the launching cylinder 9, the pipeline pigging device is recovered by the receiving cylinder 11.

[0056] During the specific implementation process, the air compressor 10 can adopt a mobile air compressor 10 to drive the pigging device for pigging with compressed air as the power, and control the speed of the pigging device at 3-4 Km per hour. A pressure gauge can be provided at the head end of the launching cylinder 9, and the pressure gauge data can be recorded every 15 minutes to master the operation situation of the pigging device for timely handling in case of problems. Both the receiving cylinder 11 and the launching cylinder 9 are provided with air release valves to facilitate the release of compressed air. The receiving cylinder 11 can also be provided with a sewage discharge valve.

[0057] Pipeline cleaning standard: When the pigging device reaches the end of pigging, the main body of the pigging device does not undergo serious deformation, ensuring the smoothness of the pipeline interior. After the pigging device is taken out, it is qualified if there is no debris accumulation and no water flowing out at the sewage outlet.
