Detailed Implementation

[0027] To enable those skilled in the art to better understand this application, the technical solution of this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] The 20-roll reversible cold rolling mill is primarily responsible for rolling pickled hot-rolled coils to the target thickness required by customers, which is crucial for product quality and process control. The belt winding aid is located on the coiler; due to its frequent use, the belt wears out quickly. Therefore, a belt replacement device for the belt winding aid is provided.

[0029] In the embodiments of this application, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a belt replacement device for a belt winder is disclosed. The belt replacement device 100 includes a first clamping assembly 110 and a second clamping assembly 120. The first clamping assembly 110 includes a first frame 111 and a first crossbeam 112 disposed on the first frame 111. The first frame 111 has a first hinge end and a first connecting end disposed opposite to each other. The second clamping assembly 120 includes a second frame 121, an adjusting member 123, and a second crossbeam 122 disposed on the second frame 121. The second frame 121 has a second hinge end and a second connecting end disposed opposite to each other. The second connecting end is connected to the first connecting end. The connection is fixed or unfixed; the second hinge end is hinged to the first hinge end, and a gap is provided at the hinge for the belt 200 of the belt 200 winder to pass through; wherein, when the first frame 111 and the second frame 121 are open, the belt 200 passes through the gap between the second hinge end and the first hinge end until it passes through the other end; when the first frame 111 and the second frame 121 are closed, the second connecting end is fixedly connected to the first connecting end, and the output end of the adjusting member 123 acts on the second crossbeam 122 to make the second crossbeam 122 misaligned relative to the first crossbeam 112 to clamp the belt 200.

[0030] like Figure 3 and Figure 4As shown, both the first frame 111 and the second frame 121 are rectangular. The first frame 111 includes a first horizontal side a, a first horizontal side b, a first vertical side a, and a first vertical side b. The second frame 121 includes a second horizontal side a, a second horizontal side b, a second vertical side a, and a second vertical side b. The first horizontal side a has a first hinge end, and the second horizontal side a has a second hinge end. The first hinge end of the first horizontal side a and the second hinge end of the second horizontal side a can be hinged together by a pin. The first horizontal side b has a first connecting end, and the second horizontal side b has a second connecting end. The first crossbeam 112 and the second crossbeam 122 are respectively located in the rectangles enclosed by the first frame 111 and the second frame 121. An adjusting member 123 is provided on the second frame 121. The driving end of the adjusting member 123 can be manual. When the adjusting member 123 is manually driven, its output end acts on the second crossbeam 122 to move the second crossbeam 122.

[0031] Thus, the belt 200 passes through the gap between the second hinge end and the first hinge end and exits from the other end. The first frame 111 rotates downward, causing the first frame 111 to close with the second frame 121. The first frame 111 and the second frame 121 are connected and fixed, which can be done by fasteners or other methods, thus achieving the first clamping of the belt. By adjusting the adjusting component 123, the second crossbeam 122 is moved, causing the belt 200 to form an "S" shape and be clamped, thus achieving the second clamping of the belt. The tail of the old belt 200 is connected to the head of the new belt 200. The old belt 200 can be pulled manually by the belt 200 replacement device, and the old belt 200 pulls the new belt 200 into the belt 200 winding device, thus completing the replacement of the belt 200 in the belt 200 winding device. Alternatively, the replacement device can be connected and fixed to a hoisting traction machine, and then hoisting and traction can be performed, saving labor compared to the previous manual dragging. Furthermore, the belt 200 replacement device of this application has a simple structure and is easy to operate in the narrow space of the belt 200 winder area. The belt 200 can be easily clamped and fixed by the double clamping method of the replacement device, making it easy to replace and improving safety.

[0032] like Figure 2 As shown, in some embodiments, the distance of the second crossbeam 122 relative to the second hinge end is less than the distance of the first crossbeam 112 relative to the first hinge end. This facilitates adjustment of the movement of the second crossbeam 122 via the adjusting member 123, allowing the second crossbeam 122 to be misaligned with the first crossbeam 112. This misalignment of the first crossbeam 112 and the second crossbeam 122 can clamp the belt 200 into an S-shape, increasing the clamping force of the belt 200.

[0033] like Figure 2As shown, in some embodiments, the first crossbeam 112 is parallel to the second crossbeam 122; the direction of movement of the second crossbeam 122 is angled to the second hinge end. The adjusting member 123 adjusts the movement of the second crossbeam 122. When the first frame 111 and the second frame 121 are closed, the misalignment of the first crossbeam 112 and the second crossbeam 122 can clamp the belt 200 into an S-shape, thereby increasing the clamping force of the belt 200.

[0034] like Figure 2 As shown, in some embodiments, both the first crossbeam 112 and the second crossbeam 122 are parallel to the second hinge end; the direction of movement of the second crossbeam 122 is perpendicular to the second hinge end.

[0035] like Figure 2 and Figure 4 As shown, in some embodiments, adjusting members 123 are disposed at both ends of the second crossbeam 122; the adjusting member 123 includes a lead screw 1231 and a nut 1232 cooperating with the lead screw 1231. The lead screw 1231 is rotatably disposed on the second frame 121, and the nut 1232 is disposed on the second crossbeam 122. There are two sets of adjusting members 123, respectively located on both sides of the second crossbeam 122, and the nuts 1232 are both disposed on the second crossbeam 122, with the lead screw 1231 cooperating with the nut 1232. In some embodiments, the lead screw 1231 is mounted on the second frame 121. To facilitate the mounting of the lead screw 1231 on the second frame 121, the end of the second horizontal side b of the second frame 121 is provided with a mounting position, that is, the second horizontal side b is provided with a mounting hole. The lead screw 1231 passes through the mounting hole and cooperates with the nut 1232 provided on the second crossbeam 122. The end of the lead screw 1231 is provided with an adjusting handwheel 1233. By rotating the adjusting handwheel 1233, the second crossbeam 122 can be moved, thereby cooperating with the first crossbeam 112 to make the belt 200 form an "S" shape and clamp it.

[0036] like Figure 2 and Figure 4 As shown, in some other embodiments, one end of the lead screw 1231 is provided with an adjusting handwheel 1233 and the other end is provided with a locking handwheel 1241. Before adjustment, the locking handwheel 1241 can be loosened. After adjustment, the adjusting locking handwheel 1241 can be used to lock and fix the lead screw 1231 to prevent the lead screw 1231 from loosening during the adjustment process or due to vibration.

[0037] like Figure 2 and Figure 4As shown, in some embodiments, the second crossbeam 122 is provided with a groove or sliding hole that is slidably connected to the second frame 121. The two ends of the second crossbeam 122 are provided with grooves or sliding holes that mate with the second vertical side a and the second vertical side b of the second frame 121. The second crossbeam 122 can be slidably connected along the second vertical side a and the second vertical side b, and serves as a guide during the adjustment of the movement of the second crossbeam 122 by the adjusting member 123.

[0038] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the first connecting end and the second connecting end each have a locking hole 113 and a locking member 124 that mates with the locking hole 113. The locking member 124 is removed from the locking hole 113 to release the fixation, thereby opening the first frame 111 and the second frame 121, allowing the belt 200 to pass through the gap between the second hinge end and the first hinge end until it exits from the other end. The locking member 124, in conjunction with the locking hole 113, connects and fixes the first frame 111 and the second frame 121, thereby closing the first frame 111 and the second frame 121 and clamping the belt 200. In some embodiments, the locking member 124 includes a threaded rod and a lock nut that mates with the threaded rod. The locking hole 113 has an internal thread that mates with the threaded rod, and the end of the threaded rod has a locking handwheel 1241, facilitating rotation to adjust the threaded rod's engagement with the locking hole 113 and the lock nut, thereby connecting and fixing the first frame 111 and the second frame 121. To avoid interference between the locking element and the belt 200, in some embodiments, the locking element is provided in two sets, and the distance between the two sets of locking elements is greater than the width of the belt 200.

[0039] like Figure 2 and Figure 4 As shown, in some embodiments, at least one of the first crossbeam 112 and the first frame 111 is provided with a rubber block 130 at a position opposite to the first frame 111 and the second frame 121; when the belt 200 passes through the hinge of the first frame 111 and the second frame 121 until it passes through the other end, and the first frame 111 and the second frame 121 are closed, the friction force can be increased at the point where the first crossbeam 112 clamps the belt 200 and at the point where the first frame 111 clamps the belt 200, making it less likely for the belt 200 to fall off.

[0040] like Figure 2 and Figure 4As shown, in some embodiments, at least one of the second crossbeam 122 and the second frame 121 is provided with a rubber block 130 at a position opposite to the first frame 111 and the second frame 121. When the belt 200 passes through the hinge joint between the first frame 111 and the second frame 121 and exits from the other end, and the first frame 111 and the second frame 121 are closed, the friction force can be increased at the points where the first crossbeam 112 clamps the belt 200 and the points where the first frame 111 clamps the belt 200, making it less likely for the belt 200 to fall off.

[0041] like Figure 2 and Figure 4 As shown, in some embodiments, at least one of the first crossbeam 112 and the second crossbeam 122 is provided with a protrusion at a position opposite to the first crossbeam 112 and the second crossbeam 122; the protrusion portion of the first crossbeam 112 and the protrusion portion of the second crossbeam 122 can clamp the belt 200 to make the belt 200 into an "S" shape, thereby achieving the clamping of the belt 200.

[0042] like Figure 2 and Figure 4 As shown, in some other embodiments, the rubber block 130 is provided on the protrusion, which can increase the friction between the protrusion and the belt 200, making the belt 200 less likely to fall off.

[0043] In order to ensure that the belt can be clamped, in some embodiments, the lengths of the first crossbeam 112 and the second crossbeam 122 are both greater than the width of the belt, and in order not to interfere with other areas, the length of the protrusion is matched with the width of the belt 200, and the length of the protrusion can be slightly greater than the width of the belt 200.

[0044] like Figure 3 As shown, in some embodiments, the first frame 111 and the second frame 121 are further provided with a lifting area 140. The lifting area 140 is located at the corner of the first connecting end and the second connecting end, and the lifting strap is fixed in the lifting area 140, so that the first frame 111 and the second frame 121 are not easily loosened by the tension.

[0045] Therefore, the belt replacement device of this application, when replacing the belt, connects the tail of the old belt to the head of the new belt. With the first frame 111 and the second frame 121 open, the old belt 200 is inserted through the gap between the second hinge end and the first hinge end until it exits from the other end. The first frame 111 and the second frame 121 are then closed, with the first connecting end and the second connecting end in contact, and connected and fixed by fasteners, clamping the first frame 111 and the second frame 121. Rotating the adjusting component 123 moves the second crossbeam 122, thereby misaligning the second crossbeam 122 with the first crossbeam 112, making the old belt 200 form an "S" shape and clamp it, locking the adjusting component 123. The sling is fixed in the lifting area 140, and the old belt 200 can be pulled downwards by hoisting, and the old belt 200 pulls the new belt into the belt winding device. With this device in operation, two people can complete the belt replacement operation.

[0046] Through the above embodiments, this application has the following beneficial effects or advantages:

[0047] The belt 200 replacement device of this application has a simple structure and is easy to operate in the narrow space of the belt 200 winder area. The belt 200 can be easily clamped and fixed by the replacement device, making it easy to replace and improving safety.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.
