It should be understood that the structures, ratios, sizes, and the like shown in the drawings and described in the specification are only used for matching with the disclosure of the specification, so as to be understood and read by those skilled in the art, and are not used to limit the conditions under which the present invention can be implemented, so that the present invention has no technical significance, and any structural modification, ratio relationship change, or size adjustment should still fall within the scope of the present invention without affecting the efficacy and the achievable purpose of the present invention. In addition, the terms "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not to be construed as a scope of the present invention.
As shown in fig. 1 to 4, the invention provides a double-sided shears pinch roll sleeve pipe dismounting tool, wherein one end of a double-sided shears pinch roll 1 is sleeved with a sleeve pipe 2 and comprises a pneumatic device for expanding the sleeve pipe 2, a plurality of fixing structures 3 are arranged around the outer side of the other end of the double-sided shears pinch roll 1, a plurality of connecting structures 4 are arranged around the outer side of the sleeve pipe 2, and a traction cable chain 5 is arranged between each fixing structure 3 and each connecting structure 4.
When the double-sided shears pinch roll sleeve dismounting tool is used for dismounting the sleeve 2 of the double-sided shears pinch roll 1, the pulling cable chain 5 is connected between the connecting structure 4 on the sleeve 2 and the fixing structure 3 on the double-sided shears pinch roll 1, so that when the sleeve 2 is expanded by the pneumatic device, the sleeve 2 is pulled by the pulling cable chain 5 and cannot fly away from the double-sided shears pinch roll 1 to hurt personnel or equipment even if the sleeve axially pops up under the action of high-pressure gas. Therefore, the bilateral scissors pinch roll sleeve dismounting tool and the operation method thereof can enable dismounting operation to be safer, and reduce safety risks of personnel and equipment.
When dismantling bilateral scissors pinch roll 1 sleeve pipe 2, because be the tight fit between sleeve pipe 2 and the pinch roll, so need adopt pneumatic means to expand sleeve pipe 2 and make sleeve pipe 2 not hard up, as shown in figure 1, pneumatic means is high-pressure pneumatic pump 11, be equipped with air inlet 12 on the sleeve pipe 2, high-pressure pneumatic pump 11 passes through the gas-supply pipe 13 and is connected with air inlet 12. High-pressure gas easily causes the casing 2 to pop out to injure people or equipment, and in the technical scheme of the invention, because the pulling cable chain 5 is connected between the casing 2 and the pinch roll, the pulling cable chain 5 can pull the casing 2, so that the casing 2 is prevented from popping out.
As a preferred embodiment, as shown in fig. 1 and fig. 2, a fixing frame 6 is sleeved at the other end of the pinch roll 1 of the double-sided shears, and the plurality of fixing structures 3 are first connecting holes 7 arranged on the fixing frame 6; as shown in fig. 4, the fixing frame 6 has a U-shaped opening, a locking chain is connected between two side edges of the U-shaped opening, a connecting lug 15 is arranged on the fixing frame 6, and the first connecting hole 7 is arranged on the connecting lug 15. The plurality of connection structures 4 are arranged on the outer side of the casing 2. The connecting structure 4 is an L-shaped connecting frame 9 fixed at the end of the casing 2, please refer to fig. 3, the L-shaped connecting frame 9 is provided with a second connecting hole 10. Both ends of the pulling chain 5 are provided with coupling hooks 14, and the coupling hooks 14 of both ends of the pulling chain 5 are respectively hooked in the first coupling hole 7 and the second coupling hole 10.
As a preferred embodiment, as shown in fig. 1 and fig. 2, a chain block 8 is connected between the fixing structure 3 and the connecting structure 4, the pulling rope chain 5 is a chain of the chain block 8, and two ends of the pulling rope chain 5 are provided with connecting hooks 14. In this way, the length of the pull chain 5 can be easily adjusted by the chain block 8. In order to enable the haul-off chain 5 to effectively prevent the casing 2 from popping out and also to enable the haul-off chain 5 not to affect the dismantling operation so that the casing 2 can move within a certain range, the haul-off chain 5 should be slack.
When the sleeve 2 on the pinch roll is dismounted, the manufactured fixing frame 6 is connected to the pinch roll, the manufactured L-shaped connecting frame 9 is connected to the sleeve 2, the connecting hooks 14 at two ends of the pulling cable chain 5 of the chain block 8 are connected into the first connecting hole 7 and the second connecting hole 10, the pulling chain is slightly loose (the stroke is about 100 plus 150 mm), the sleeve 2 is expanded by starting the high-pressure pneumatic pump 11 to 1500 plus 2000bar at the moment, and the forward ejection force potential safety hazard is extremely high due to the fact that the sleeve 2 is expanded in a conical shape, and the double-sided shear pinch roll sleeve dismounting tool effectively prevents the sleeve from being ejected forwards, so that the dismounting work is finished.
Corresponding to the bilateral scissors pinch roll sleeve dismounting tool, the invention also provides a using method of the bilateral scissors pinch roll sleeve dismounting tool, the bilateral scissors pinch roll sleeve dismounting tool is used for operating, and the method comprises the following steps:
1) a connecting structure 4 is arranged on the outer side of the sleeve 2, and a fixing structure 3 is arranged on the pinch roll 1 of the double-sided shears;
2) connecting the pull chain 5 between the fixed structure 3 and the connecting structure 4, with the pull chain 5 in a slack condition;
3) Connecting a pneumatic device with the sleeve 2;
4) the pneumatic device is started to expand the casing 2 and move the casing 2 axially relative to the pinch roll 1 of the double-sided shears so as to detach the casing 2.
The use method of the double-sided shears pinch roll sleeve dismounting tool provided by the invention has the beneficial effects of the double-sided shears pinch roll sleeve dismounting tool provided by the invention, and details are not repeated here.
Based on the technical scheme, the dismounting tool for the pinch roll sleeve of the double-sided shear and the using method thereof can enable dismounting operation to be safer, and enable the dismounting operation to be safe and convenient.
In conclusion, the present invention effectively overcomes various disadvantages of the prior art and has high industrial utilization value.
