Abstract
Description
Technical Field
[0001] The utility model relates to the field of roller door locking tool design, in particular to a roller door locking device. Background Art
[0002] The hot rolling roll locking device is installed on the operating side of the mill. Its main function is to limit the large axial movement of the working roll (the axial movement is not more than 5mm) and affect the quality of the rolled billet. However, due to the unreasonable structural design of the existing technology, the gap between the locking plate and the working roll bearing seat is uneven. When the working roll bearing seat is against the locking plate lining, the locking plate is tilted to the outside and has poor guidance, which causes the locking plate to be unable to open, affecting the progress of the roll change. When the locking plate cannot be opened, it is usually necessary to use the roll change trolley to push the working roll to the transmission side to open the locking plate, so the above problems need to be solved. Utility Model Content
[0003] The technical problem to be solved by the utility model is that when the working roll bearing seat is abutted against the lock door plate lining plate, the lock door plate is tilted outwards and has poor guiding performance, so that the lock door plate cannot be opened, affecting the progress of roll replacement.
[0004] In order to solve the above problems, the technical solution adopted by the utility model is as follows: the utility model is a rolling mill door locking device, including a rough rolling arch and a bearing seat ear shoulder, the bearing seat ear shoulder is arranged on the rough rolling arch, and the bearing seat ear shoulder is symmetrically arranged in two groups, and also includes a guide fixing bolt group, a guide plate, a mover, a support and a door locking cylinder, the guide fixing bolt group is arranged in two groups, the guide fixing bolt group is arranged on the rough rolling arch, the guide plate is arranged in two groups, the guide plates are respectively arranged on one group of guide fixing bolt groups, the mover is slidably sleeved on the guide fixing bolt group, the support is installed on the rough rolling arch, and the door locking cylinder is connected between the support and the mover.
[0005] Furthermore, the mover includes a door lock plate, a lead screw, a nut, an adjustment block, a first fixing bolt and a lining plate, the door lock plate is provided with a moving opening, the guide fixing bolt group is located in the moving opening, the door lock plate is slidably arranged on the guide fixing bolt group and is connected to the door lock cylinder, the door lock plate is slidably arranged on the guide plate, the door lock plate is penetrated with adjustment holes on the upper and lower sides, the lead screw slides through the adjustment hole, the nut is threadedly connected on the lead screw and is in contact with the door lock plate, a plurality of mounting holes are provided on the door lock plate, the adjustment block is provided with two groups, the adjustment block is sleeved on the lead screw and penetrates the mounting holes, the first fixing bolt is installed on the adjustment block, the first fixing bolt is in contact with the door lock plate, and the lining plate is installed on the adjustment block.
[0006] The beneficial effects achieved by the utility model using the above structure are as follows: the reasonable design of the guide structure of the door lock plate can ensure the reliable operation of the locking plate and high opening and closing accuracy; when the door lock plate cannot be opened, the lining plate gap adjustment mechanism is used to adjust the gap between the lining plate and the ear shoulder of the bearing seat, so that the door lock plate can be quickly opened, greatly improving the progress of roller replacement.
