Description

Technical Field

[0001] This utility model relates to the technical field of pipeline cleaning devices, and in particular to a pipeline clamping mechanism and a pipeline cleaning device. Background Technology

[0002] Pipe cleaning refers to cleaning pipes to restore the original surface of the pipe material. After production, expandable rubber hoses need to have their inner walls cleaned using a pipe cleaning device. To clean the inner walls using this device, a cleaning cartridge of the appropriate size is first placed inside the expandable rubber hose. Then, high-pressure gas and / or high-pressure liquid are introduced. The high-pressure gas and / or high-pressure liquid propels the cleaning cartridge along the inner wall of the expandable rubber hose to the other end, thus completing the cleaning of the inner wall of the expandable rubber hose.

[0003] Existing pipe cleaning devices require manual placement of the end of the expandable rubber hose to be cleaned onto the pipe cleaning gun. Because the cleaning gun introduces high-pressure gas and / or high-pressure liquid into the expandable rubber hose, this poses a safety hazard to operators during cleaning. Therefore, there is a need to design a pipe clamping mechanism and pipe cleaning device that can clamp and secure the end of the expandable rubber hose to be cleaned, replacing the current manual operation and thus avoiding danger to operators during cleaning. Utility Model Content

[0004] To address the problems in the prior art, this application proposes a pipe clamping mechanism and a pipe cleaning device, which can clamp and fix the end of the expandable rubber pipe to be cleaned, replacing the existing manual operation and thus avoiding danger to operators during cleaning.

[0005] One aspect of this utility model provides a pipe clamping mechanism, which includes a support frame. A first clamping block is installed on the lower side of the support frame, and a telescopic drive is installed on the upper side of the support frame. The telescopic end of the telescopic drive extends into the support frame, and a second clamping block is installed on the telescopic end of the telescopic drive. The extension of the telescopic end of the telescopic drive can drive the second clamping block to approach the first clamping block to clamp the end of an expandable rubber tube. First vertical guide holes are provided on both side walls of the support frame, and first guide rods are provided on both side walls of the second clamping block. The first guide rods on both sides are correspondingly limited and slidably in the first vertical guide holes on both sides.

[0006] As a further improvement to the above technical solution:

[0007] Furthermore, in the aforementioned pipe clamping mechanism, a limiting groove is formed in the middle of the upper surface of the first clamping block, and the telescopic end of the telescopic drive member extends to drive the second clamping block to be confined in the limiting groove and to move downward along the limiting groove.

[0008] In the aforementioned pipe clamping mechanism, a threaded sleeve is further installed on the lower side of the support frame, and a threaded drive rod is installed in the threaded sleeve. The first clamping block is rotatably installed on the upper end of the threaded drive rod. A second vertical guide hole is provided on both sides of the support frame, and a second guide rod is provided on both sides of the first clamping block. The second guide rods on both sides are correspondingly limited and slid in the second vertical guide holes on both sides.

[0009] Furthermore, in the aforementioned pipe clamping mechanism, a drive handle is installed at the lower end of the threaded drive rod, and the drive handle is used to drive the threaded drive rod to rotate.

[0010] Furthermore, in the aforementioned pipe clamping mechanism, the mating end faces of the first clamping block and the second clamping block are V-shaped.

[0011] Another aspect of this utility model provides a pipe cleaning device, which includes a pipe cleaning gun and a pipe clamping mechanism as described above. The pipe clamping mechanism can clamp and fix the end of the expandable rubber tube to be cleaned, and make the end of the expandable rubber tube sleeved on the pipe cleaning gun.

[0012] The above-mentioned technical features can be combined in various suitable ways or replaced by equivalent technical features, as long as the purpose of this utility model can be achieved.

[0013] This utility model provides a pipe clamping mechanism and pipe cleaning device, which, compared with the prior art, has at least the following advantages: When it is necessary to clean the inner wall of an expandable rubber tube, the end of the expandable rubber tube to be cleaned is first placed between the first clamping block and the second clamping block, and the end of the expandable rubber tube to be cleaned is sleeved on the pipe cleaning gun. Then, the telescopic end of the telescopic drive extends to drive the second clamping block closer to the first clamping block to clamp the end of the expandable rubber tube. Finally, the pipe cleaning gun delivers a cleaning bullet into the expandable rubber tube and cleans the inner wall of the expandable rubber tube. The first guide rod slides in the first vertical guide holes on both sides, which can guide the movement of the second clamping block, thereby improving the clamping stability of the end of the expandable rubber tube. This pipe clamping mechanism can clamp and fix the end of the expandable rubber tube to be cleaned, replacing the existing manual operation, thereby avoiding danger to operators during cleaning.

[0029] This utility model provides a pipe clamping mechanism that can clamp and fix the end of an expandable rubber tube to be cleaned, replacing the existing manual operation and thus avoiding danger to operators during cleaning.

[0030] Please see Figure 1 and Figure 2 The pipe clamping mechanism 100 provided in this embodiment of the utility model includes a support frame 110. A first clamping block 120 is installed on the lower side of the support frame 110. A telescopic drive member 130 is installed on the upper side of the support frame 110. The telescopic end of the telescopic drive member 130 extends into the support frame 110, and a second clamping block 140 is installed on the telescopic end of the telescopic drive member 130. The extension of the telescopic end of the telescopic drive member 130 can drive the second clamping block 140 to approach the first clamping block 120 to clamp the end of the expandable rubber tube. First vertical guide holes 111 are provided on both sides of the support frame 110, and first guide rods 141 are provided on both sides of the second clamping block 140. The first guide rods 141 on both sides are correspondingly limited and slid in the first vertical guide holes 111 on both sides.

[0031] When cleaning the inner wall of the expandable rubber tube, the end of the expandable rubber tube to be cleaned is first placed between the first clamping block 120 and the second clamping block 140, and then the end of the expandable rubber tube to be cleaned is sleeved on the pipeline cleaning gun. Then, the telescopic end of the telescopic drive 130 extends to drive the second clamping block 140 to approach the first clamping block 120 to clamp the end of the expandable rubber tube. Finally, the pipeline cleaning gun delivers a cleaning bullet into the expandable rubber tube and cleans the inner wall of the expandable rubber tube. The first guide rod 141 slides in the first vertical guide holes 111 on both sides, which can guide the movement of the second clamping block 140, thereby improving the clamping stability of the end of the expandable rubber tube.

[0032] The pipe clamping mechanism 100 provided in this embodiment of the present invention can clamp and fix the end of the expandable rubber tube to be cleaned, replacing the existing manual operation, thereby avoiding danger to the operator during cleaning.

[0033] The pipe clamping mechanism 100 provided in this embodiment of the utility model, further please refer to... Figure 1 and Figure 3The first clamping block 120 and the second clamping block 140 have V-shaped mating end faces. A limiting groove 121 is provided in the middle of the upper surface of the first clamping block 120. The telescopic end of the telescopic drive member 130 extends to drive the second clamping block 140 to be limited in the limiting groove 121 and to move downward along the limiting groove 121. When the telescopic drive 130 extends to drive the second clamping block 140 to approach the first clamping block 120 to clamp the end of the expandable rubber tube, the second clamping block 140 presses the expandable rubber tube from the upper side of the end of the expandable rubber tube, and the first clamping block 120 supports the expandable rubber tube from the lower side of the end of the expandable rubber tube. Since the limiting groove 121 is opened in the middle of the upper surface of the first clamping block 120, the first clamping blocks 120 on both sides of the limiting groove 121 simultaneously support the lower side of the end of the expandable rubber tube, thereby avoiding shearing force when the second clamping block 140 and the first clamping block 120 cooperate to clamp the end of the expandable rubber tube, thus improving clamping stability.

[0034] The pipe clamping mechanism 100 provided in this embodiment of the utility model, further please refer to... Figure 1 and Figure 2 A threaded sleeve 112 is installed on the lower side of the support frame 110. A threaded drive rod 150 is installed in the threaded sleeve 112 with internal thread engagement. A first clamping block 120 is rotatably installed on the upper end of the threaded drive rod 150. Second vertical guide holes 113 are provided on both side walls of the support frame 110. Second guide rods 122 are provided on both side walls of the first clamping block 120. The second guide rods 122 on both sides slide and are limited in the second vertical guide holes 113 on both sides. A drive handle 151 is installed on the lower end of the threaded drive rod 150, and the drive handle 151 is used to drive the threaded drive rod 150 to rotate. Since the installation height of the pipeline cleaning gun is fixed, the height of the first clamping block 120 needs to be adjusted for expandable rubber tubes of different diameters to be cleaned, so that the expandable rubber tubes to be cleaned can be aligned and fitted onto the pipeline cleaning gun. The second guide rods 122 on both sides are correspondingly limited and slidable in the second vertical guide holes 113 on both sides, which can guide the movement of the first clamping block 120 and prevent the first clamping block 120 from rotating with the threaded drive rod 150.

[0035] In this embodiment, please refer to Figure 1 and Figure 2The first guide rod 141 and the second guide rod 122 are both guide screws. Threaded holes are provided on both side walls of the first clamping block 120 and the second clamping block 140. The end of the guide screw passes through the first vertical guide hole 111 or the second vertical guide hole 113 and is threaded into the threaded hole. The support frame 110 includes two vertical side plates 114, an upper end plate 115, and a lower end plate 116. The first vertical guide hole 111 and the second vertical guide hole 113 are provided on the vertical side plates 114. The telescopic drive component 130 is mounted on the upper end plate 115, and the threaded sleeve 112 is mounted on the lower end plate 116.
