Abstract
Description
Technical Field
[0001] The utility model relates to a cold rolling mill roll placing rack. Background Art
[0002] The cold rolling mill roll rack is a device for storing and placing rolls, which is usually located around the cold rolling mill equipment or on the side of the production line. These racks are designed to facilitate the storage, management and maintenance of rolls. In the prior art, there are the following defects: some existing cold rolling mill roll racks are integrated, and special roll racks need to be customized. However, it takes a certain amount of time to customize special roll racks, and they cannot be adjusted according to rolls of different lengths, which reduces the practicality of the device to a certain extent. On the other hand, some cold rolling mill roll racks are equipped with special moving wheels at the bottom. Generally, the moving wheels of the roll racks have a self-locking function. However, if the self-locking mechanism of the moving wheels is used for a long time, the friction may be reduced, and the locking may not be tight enough. In addition, although the moving wheels have a self-locking function, the contact area with the ground is small, and there is still a possibility of movement in the event of collision.

The outer wall of the driving mechanism is threadedly connected with a moving plate 4, and the moving plates 4 are in two groups. When the bidirectional screw rod 3 rotates, the two groups of moving plates 4 will be separated from or brought closer to each other. The top of the moving plate 4 is elastically connected with a limiting block 6 through a return spring 5, and the limiting block 6 is plugged into the upper limit groove 8 of the connecting pipe 7 to keep the position of the connecting pipe 7 unchanged. The inner wall of the moving plate 4 is penetrated by and slidably connected with a connecting pipe 7, and the top of the connecting pipe 7 is provided with a limiting groove 8, and the right end of the connecting pipe 7 is fixedly connected with a load-bearing frame 9. By placing the roller on the bearing The heavy rack 9 is stored to facilitate the subsequent taking of rollers of different lengths. The right end side wall of the placement rack 1 is fixedly connected with a support block 10, and a vertical opening is opened on the support block 10. The vertical opening can allow a card block 12 to vertically pass through the support block 10, and the interior of the support block 10 is in the shape of a ring groove, which can allow the slide bar 11 to rotate with the card block 12 inside the support block 10. The middle part of the support block 10 is penetrated and slidably connected with a slide bar 11, and the outer wall of the slide bar 11 is fixedly connected with a card block 12, and the card block 12 is arranged in two groups. The card block 12 on the outer wall of the upper end of the slide bar 11 can allow the upper end card block 12 of the slide bar 11 to be clamped and limited with the inner wall of the support block 10 after the contact block 15 contacts the ground, and the outer wall card block 12 at the lower end of the slide bar 11, such as Figure 3 As shown, when the bottom plate 13 and the contact block 15 are not in use, the outer wall block 12 at the lower end of the slide bar 11 is engaged with the inner wall of the support block 10 to limit the position, and the bottom end of the slide bar 11 is rotatably connected to the bottom plate 13, as shown in FIG. Figure 3As shown, a vertical tube is fixed to the top left side of the bottom plate 13, and the vertical tube slides with the support block 10 of the left side wall of the placement rack 1. The vertical tube can ensure the vertical movement of the bottom plate 13, and the movement trajectory will not produce a deviation to reach the guiding effect. A contact mechanism is provided at the bottom end of the bottom plate 13; the contact mechanism includes a contact block 15, which is made of rubber material and can contact the ground to increase its friction and contact point with the ground. The contact block 15 penetrates and is slidably connected to the inner wall of the bottom plate 13, and the top of the contact block 15 is fixedly connected There is one end of a positioning spring 14. When the contact block 15 contacts the ground, the positioning spring 14 will be compressed, and the elastic force of the positioning spring 14 will keep the contact block 15 in contact with the ground at all times. The other end of the positioning spring 14 is fixedly connected to the top inner wall of the bottom plate 13, and the clamping block 12 is clamped with the inner wall of the support block 10; the driving mechanism includes a partition plate 2, which can locate the moving distance of the two groups of load-bearing frames 9, and the partition plate 2 mainly supports and connects the entire bidirectional screw rod 3. The partition plate 2 passes through and is fixedly connected to On the inner wall of the placement rack 1, a bidirectional screw rod 3 is penetrated and rotatably connected to the inner wall of the partition plate 2. The bidirectional screw rod 3 usually has two symmetrical threads, so that it can transmit movement in the forward and reverse directions at the same time. This symmetrical design helps to balance the force and improve stability. The outer wall of the bidirectional screw rod 3 is threadedly connected to the middle part of the moving plate 4. The top of the moving plate 4 is fixedly connected to one end of the reset spring 5. When the limit block 6 moves upward, the reset spring 5 will be stretched. When resetting, the elastic force of the reset spring 5 is used to reset the limit block 6. The other end of the return spring 5 is fixedly connected to the inner side wall of the limit block 6, the limit block 6 passes through and is slidably connected to the inner wall of the movable plate 4, the limit block 6 is plugged into the inner wall of the limit groove 8, the load-bearing frame 9 is slidably connected to the bottom inner wall of the placement frame 1, and a notch is provided on the bottom inner wall of the placement frame 1, so that the load-bearing frame 9 can slide along the notch of the placement frame 1, the movable plate 4 passes through and is slidably connected to the right end side wall of the placement frame 1, and a notch is provided on the right end side wall of the placement frame 1, so that the movable plate 4 can move with the entire load-bearing frame 9.
[0012] When the roller needs to be placed first, it is only necessary to adjust the load-bearing frame 9 according to the longest length of the roller. By rotating the two-way screw rod 3, the movable plate 4, the connecting pipe 7 and the load-bearing frame 9 are moved relatively, so that the distance between the two groups of load-bearing frames 9 is brought closer and the rollers can be placed on the two groups of load-bearing frames 9. When a shorter roller needs to be placed, one group of load-bearing frames 9 can be adjusted separately. It is only necessary to pull the limit block 6 upwards and stretch the reset spring 5 to separate the limit block 6 from the notch of the limit groove 8. Then, the load-bearing frame 9 is moved by moving the connecting pipe 7, so that the two pairs of load-bearing frames 9 can be moved relatively, so that a shorter roller can be placed between the two pairs of load-bearing frames 9. Finally, the limit block 6 is released and the reverse elastic force of the reset spring 5 is used to reset the limit block 6, so that the limit block 6 is plugged into the inner wall of the limit groove 8 to limit the entire connecting pipe 7. When the load-bearing frame 9 and the movable plate 4 need to be completely reset to the initial state, it is only necessary to follow the above steps.
[0013] Finally, the slide bar 11 is rotated to engage the upper end block 12 with the inner ring groove of the support block 10, and the contact block 15 is contacted with the ground by contacting the upper and lower end blocks 12 and the bottom plate 13, and the contact block 15 and the vertical tube are overlapped.
[0014] When the placement rack 1 needs to be moved, it is only necessary to follow the second step to move the slide bar 11 with the entire bottom plate 13 upwards, and to engage the lower end block 12 of the slide bar 11 with the inner wall of the support block 10 .
