[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: the existing height adjustment device cannot integrate its own structure into the rolling mill equipment, thus occupying other space on the rolling mill production line, resulting in low space utilization. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that existing height adjustment devices cannot be integrated into the rolling mill equipment, thus occupying other space on the rolling mill production line and resulting in low space utilization. This invention provides an adjustment device for rolling mill equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] The present invention discloses an adjustment device for steel rolling equipment, comprising a drive cylinder; a movable block is detachably threaded to the lower end of the drive cylinder; a support plate is rotatably connected to the drive cylinder; a pull rod is inserted into symmetrically opened holes in the support plate; a lever bracket is pinned to the lower end of the pull rod; a fixed tube is inserted into one end of the lever bracket; fixed seats are fixed to both ends of the fixed tube; a fixed plate is fixed to the other end of the lever bracket; and a loose roller is fixed to the fixed plate.

[0008] Furthermore, a connecting seat is fixedly connected to the upper end of the drive cylinder; a fixed connecting plate is rotatably connected to the connecting seat; and the fixed connecting plate is fixed to the loop frame.

[0009] Furthermore, the looper frame has clearance grooves corresponding to the fixed plate and the looper roller.

[0010] The adjustment device for steel rolling equipment provided by this utility model has the following beneficial effects:

[0011] 1. This utility model drives the cylinder to reciprocate under the control of the solenoid valve by connecting an external pressure air source. This reciprocates the cylinder, thereby pushing the movable block, support plate, and pull rod to move up and down. The up and down movement of the pull rod pushes and pulls the lever bracket to move up and down around the fixed pipe and fixed seat, thereby moving the fixed plate and the looper roller fixed on the lever bracket up and down. This lifts the rolled steel, reducing the contact area between the rolled steel and the looper frame, and also reducing the contact pressure. This reduces the friction and pressure of the rolled steel entering from one piece of equipment to another, making the transfer of the rolled steel more stable and reliable.

[0012] 2. This utility model uses a connecting seat to make the drive cylinder and the connecting seat rotate, so that when the drive cylinder is actuated, it can rotate around the connecting seat as the center of rotation and perform stable operation; the looper frame can be adapted to the device to lift and adjust the height of the rolled steel by opening a small area of ​​clearance groove, so the improvement requirements of the looper frame are small and the difficulty is low.

[0018] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0021] Please see Figure 1-3 As shown, an adjustment device for steel rolling equipment includes a drive cylinder 1; a movable block 2 is detachably threaded to the lower end of the drive cylinder 1; a support plate 3 is rotatably connected to the drive cylinder 1; pull rods 4 are inserted into symmetrically opened holes on the support plate 3; a lever bracket 5 is pin-connected to the lower end of the pull rod 4; a fixed pipe 6 is inserted into one end of the lever bracket 5; fixed seats 7 are fixed to both ends of the fixed pipe 6; a fixed plate 8 is fixed to the other end of the lever bracket 5; a loose roller 10 is fixed to the fixed plate 8. The drive cylinder 1 is driven by an external pressure air source, thereby driving the cylinder 1 in electromagnetic... The valve controls the reciprocating motion, which in turn drives the movable block 2, support plate 3, and pull rod 4 to move up and down. The up and down movement of the pull rod 4 pushes and pulls the lever bracket 5 to move up and down around the fixed pipe 6 and fixed seat 7, thereby moving the fixed plate 8 and the looper roller 10 fixed on the lever bracket 5 up and down, thus lifting the rolled steel. This reduces the contact area between the rolled steel and the looper frame 13, and also reduces the contact pressure. This reduces the friction and pressure of the rolled steel entering from one piece of equipment to another, making the transfer of the rolled steel more stable and reliable.

[0022] A connecting seat 14 is fixedly connected to the upper end of the drive cylinder 1; a fixed connecting plate 12 is rotatably connected to the connecting seat 14; the fixed connecting plate 12 is fixed to the loose frame 13, and the drive cylinder 1 and the connecting seat 14 are rotatably connected through the connecting seat 14, so that when the drive cylinder 1 is activated, it can rotate around the connecting seat 14 as the center of rotation and perform stable operation.

[0023] The looper frame 13 has clearance grooves 11 corresponding to the fixed plate 8 and the looper roller 10. By opening clearance grooves 11 in a small area on the looper frame 13, it can be adapted to the device to lift and adjust the height of the rolled steel. Therefore, the improvement requirements of the looper frame 13 are small and the difficulty is low.

[0024] The fixed base 7 is symmetrically fixed at the lower end of the fixed connecting plate 12, so that the fixed connecting plate 12 serves as a reference connecting member. The structure fixed on the fixed connecting plate 12 achieves the support of the entire structure by the fixed connecting plate 12, so that it does not rely on the loop frame 13 and will not interfere with the structure of the loop frame 13 itself, and can be adapted to different loop frames 13.

[0025] The spacing of the pull rods 4 is greater than the width of the loop frame 13, so that the external force from the moving block 2 and the support plate 3 of the drive cylinder 1 can be transmitted through the pull rods 4 without interfering with the structure of the loop frame 13 itself, and can be adapted to different loop frames 13.

[0026] A water spray pipe 9 is inserted between the fixed plates 8. The steel can be cooled by external cold water circulation through the water spray pipe 9.
