Abstract
Description
Technical Field
[0001] The utility model relates to the field of use and installation of hot rolling mill stand rollers, in particular to a hot rolling mill stand roller anti-loosening device. Background Art
[0002] The E stand rollers of hot rolled plate mainly play a role of transportation, and the main body of the transportation is the slab.
[0003] Since the hot-rolled plate E stand roller bears a greater impact from the previous slab, the anchor bolts of the E stand roller bearing seat are easily loosened, and even all the anchor bolts fall off, causing the accident. Utility Model Content
[0004] The technical problem to be solved by the utility model is that the foundation bolts of the E-frame roller bearing seat are easy to loosen, and even all the foundation bolts fall off to cause accidents.
[0005] In order to solve the above problems, the technical solution adopted by the utility model is as follows: the utility model is a hot rolling mill stand roller anti-loosening device, including an external machine base and a bearing seat, the bearing seat is clamped and placed on the external machine base, the bearing seat is penetrated by a bearing groove, the external machine base is penetrated by a through hole, and also includes a T-bolt, a flat washer, a double-stacked self-locking washer and a nut. The top bolt head of the T-bolt is placed on the bearing seat and the lower bolt column of the T-bolt slides through the bearing groove and the through hole, the flat washer is slidably sleeved outside the T-bolt, the double-stacked self-locking washer is slidably sleeved outside the T-bolt, and the nut is threadedly connected on the T-bolt.
[0006] Furthermore, a drainage hole is provided at the lower inner portion of the bearing seat.
[0007] Furthermore, the external machine base, the flat washer, the double-stacked self-locking washer and the nut are in close contact with each other.
[0008] The beneficial effects achieved by the utility model with the above structure are as follows: the problem that the anchor bolts of the E-frame roller bearing seat are easily loosened is solved, and the probability of accidents caused by the anchor bolts all falling off is avoided. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 This is a schematic diagram of the overall structure of a hot rolling mill stand roller anti-loosening device proposed by the utility model;
[0010] Figure 2 The utility model is a partial side sectional view of a hot rolling mill stand roller anti-loosening device.
[0011] Among them, 1. external machine base, 2. bearing seat, 3. bearing groove, 4. through hole, 5. T-shaped bolt, 6. flat washer, 7. double-stacked self-locking washer, 8. nut. DETAILED DESCRIPTION
[0012] like Figure 1~Figure 2 As shown, the utility model is a hot rolling mill stand roller anti-loosening device, comprising an external machine base 1 and a bearing seat 2, the bearing seat 2 is clamped and placed on the external machine base 1, the hot rolling mill stand roller is installed on the bearing seat 2, the bearing seat 2 is penetrated by a bearing groove 3, the external machine base 1 is penetrated by a through hole 4, and also comprises a T-bolt 5, a flat washer 6, a double-stacked self-locking washer 7 and a nut 8, the top bolt head of the T-bolt 5 is placed on the bearing seat 2 and the lower bolt column of the T-bolt 5 slides through the bearing groove 3 and the through hole 4, the flat washer 6 is slidably sleeved outside the T-bolt 5, the double-stacked self-locking washer 7 is slidably sleeved outside the T-bolt 5, and the nut 8 is threadedly connected on the T-bolt 5, and a through installation method is adopted to tighten it more.
[0013] A drainage hole (not shown) is provided at the lower inner side of the bearing seat 2 to facilitate drainage. The external machine base 1, flat washer 6, double-stacked self-locking washer 7 and nut 8 are tightly fitted together to install the bearing seat 2 and the external machine base 1 together.
[0014] When using it specifically: insert the bearing seat 2 into the external machine base 1, insert the T-bolt 5 into the bearing groove 3 and the through hole 4, put on the flat washer 6, double-stack self-locking washer 7, and then tighten it with the nut 8.
[0015] It should be understood that although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
