[0038] By setting up the left and right groups of clamping mechanisms, the flange 5 and the connecting plate 1 of the first rubber lined pipe 3 and the second rubber lined pipe 4 can be reinforced from the left and right directions, and the first rubber lined pipe 3 and the second rubber lined pipe 4 can be reinforced from the upper and lower directions. In combination with the inner support ring 2 for reinforcing the inner side of the connection between the first rubber lined pipe 3 and the second rubber lined pipe 4, the connection stability between the first rubber lined pipe 3, the second rubber lined pipe 4 and the connecting plate 1 is effectively improved, thereby improving the stability between the first rubber lined pipe 3 and the second rubber lined pipe 4.
[0039] The connecting plate 1 is connected to the flange plates 5 of the first rubber-lined pipe 3 and the second rubber-lined pipe 4 by bolts 6 .
[0040] The connecting plate 1 and the flange plates 5 of the first rubber-lined pipe 3 and the second rubber-lined pipe 4 are conventionally fixed by bolts 6 .
[0041] The flange 5 is provided with a pressure block matching groove 22 .
[0042] The pressing block matching groove 22 is used to match with the pressing block 21 to clamp the flange 5 .
[0043] One end of the first bidirectional screw shaft 8 is connected to a first hand wheel 10 , and one end of the second bidirectional screw shaft 14 is installed with a second hand wheel 16 .
[0044] The first hand wheel 10 is used to rotate the first bidirectional screw shaft 8 , and the second hand wheel 16 is used to rotate the second bidirectional screw shaft 14 . The first hand wheel 10 and the second hand wheel 16 also play a supporting role for the compression spring 23 .
[0045] The first transmission block 11 is penetrated by the first bidirectional screw shaft 8 and the first guide slide rod 9 . The first bidirectional screw shaft 8 and the first transmission block 11 are threadedly connected, and the first guide slide rod 9 and the first transmission block 11 are slidably connected.
[0046] The first bidirectional screw shaft 8 rotates to drive the first transmission blocks 11 on the left and right clamping mechanisms to move toward or away from each other under the guidance of the first guide slide bar 9, so that the two clamping mechanisms move closer to or farther away from each other.
[0047] The second transmission block 20 is penetrated by the second bidirectional screw shaft 14 and the second guide slide bar 15 . The second bidirectional screw shaft 14 and the second transmission block 20 are threadedly connected, and the second guide slide bar 15 and the second transmission block 20 are slidably connected.
[0048] The second bidirectional screw shaft 14 rotates to drive the second transmission block 20 of the upper clamping arm mechanism 17 and the second transmission block 20 of the lower clamping arm mechanism 18 to move toward or away from each other under the guidance of the second guide slide bar 15, so that the upper and lower clamping arms 19 are moved closer to or away from each other.
[0049] The outer sides of the first bidirectional screw shaft 8 , the first guide slide bar 9 , the second bidirectional screw shaft 14 , and the second guide slide bar 15 are all sleeved with spring bushings 24 , and the outer sides of the spring bushings 24 are sleeved with compression springs 23 .
[0050] When the upper clamping arm mechanism 17 and the lower clamping arm mechanism 18 are separated from each other, and the left and right clamping mechanisms are away from each other, the compression spring 23 is compressed. When the upper clamping arm mechanism 17 and the lower clamping arm mechanism 18 and the left and right clamping mechanisms are close to each other, the compression spring 23 is released, and it uses the first hand wheel 10, the second hand wheel 16, and the limit plate 25 as a fulcrum to apply a force to the first transmission block 11 and the second transmission block 20, which not only increases the pressure of the clamping arm 19 and the pressure block 21 on the first rubber-lined pipe 3, the second rubber-lined pipe 4, and the flange 5, but also increases the friction between the first transmission block 11, the second transmission block 20 and the first bidirectional screw shaft 8, the second bidirectional screw shaft 14, thereby improving the stability of the first bidirectional screw shaft 8, the second bidirectional screw shaft 14, avoiding their rotation due to the vibration transmitted from the pipeline, and improving reliability.
[0051] A limiting plate 25 is disposed at one end of the first bidirectional screw shaft 8 , the first guide slide bar 9 , the second bidirectional screw shaft 14 , and the second guide slide bar 15 .
[0052] The limit plate 25 is used to prevent the first transmission block 11 from escaping from the first bidirectional screw shaft 8 and the first guide slide bar 9 and to prevent the second transmission block 20 from escaping from the second bidirectional screw shaft 14 and the second guide slide bar 15, and plays a supporting role for the compression spring 23.
[0053] The working principle and use process of the utility model: when the device is used, after aligning the first rubber-lined pipe 3 and the second rubber-lined pipe 4 with the inner support ring 2, the first rubber-lined pipe 3 and the second rubber-lined pipe 4 are respectively inserted into the inner support ring 2, and the flange 5 is aligned with the screw hole on the connecting plate 1, and then the bolt 6 is used to screw and fix the connecting plate 1 and the flange 5 in the first rubber-lined pipe 3 and the second rubber-lined pipe 4, and then the second hand wheel 16 is rotated to drive the second bidirectional screw shaft 14 to rotate, and the second transmission block 20 of the upper clamping arm mechanism 17 and the second transmission block 20 of the lower clamping arm mechanism 18 are driven to move towards each other under the guidance of the second guide slide bar 15, so that the upper and lower groups of clamping arms 19 are relative to each other. The first and second rubber-lined pipes 3 and 4 are clamped together. When the clamping arm 19 contacts the first and second rubber-lined pipes 3 and 4, the second hand wheel 16 can no longer be rotated. Subsequently, the first hand wheel 10 is rotated to drive the first bidirectional screw shaft 8 to rotate, and the first transmission blocks 11 on the left and right clamping mechanisms are driven to move toward each other under the guidance of the first guide slide bar 9, so that the two sets of clamping mechanisms are close to each other, and the pressure block 21 is inserted into the pressure block matching groove 22, and the flange 5 and the connecting plate 1 of the first and second rubber-lined pipes 3 and 4 are clamped. When the pressure block 21 is in place, the first hand wheel 10 can no longer be rotated. Through the setting of the left and right clamping mechanisms, it is possible to The flange 5 and the connecting plate 1 of the first rubber-lined pipe 3 and the second rubber-lined pipe 4 are reinforced from the left and right directions, and the first rubber-lined pipe 3 and the second rubber-lined pipe 4 can be reinforced from the upper and lower directions, and the inner support ring 2 is used to reinforce the inner side of the connection between the first rubber-lined pipe 3 and the second rubber-lined pipe 4, which effectively improves the connection stability between the first rubber-lined pipe 3, the second rubber-lined pipe 4 and the connecting plate 1, thereby improving the stability between the first rubber-lined pipe 3 and the second rubber-lined pipe 4. The device is provided with a compression spring 23. When the upper clamping arm mechanism 17 and the lower clamping arm mechanism 18 are separated from each other, and when the left and right clamping mechanisms are away from each other, the compression spring 23 is compressed. When the upper clamping arm mechanism 17 and the lower clamping arm mechanism 18 and the left and right clamping mechanisms are close to each other, the compression spring 23 is released, and the first hand wheel 10, the second hand wheel 16 and the limit plate 25 are used as fulcrums to apply a force to the first transmission block 11 and the second transmission block 20, which not only increases the pressure of the clamping arm 19 and the pressure block 21 on the first rubber-lined pipe 3, the second rubber-lined pipe 4 and the flange 5, but also increases the friction between the first transmission block 11, the second transmission block 20 and the first bidirectional screw shaft 8 and the second bidirectional screw shaft 14, thereby improving the stability of the first bidirectional screw shaft 8 and the second bidirectional screw shaft 14, avoiding their rotation due to the vibration transmitted from the pipeline, and improving reliability.
