fig. 3 is a use state diagram of the present invention.
Detailed Description
As shown in fig. 1 and 2, the special disassembling tool for the bucket elevator speed reducer provided by the utility model comprises a fixing plate 1 and a fixing screw rod 2, wherein the middle of the fixing plate 1 is provided with an installation groove 11, the periphery of the fixing plate 1 is provided with fixing holes 12, and the fixing screw rod 2 penetrates through the fixing holes 12; a fixing nut 21 is arranged at the top end of the fixing screw rod 2, an external thread 22 is arranged at the bottom end of the fixing screw rod 2, and the external thread 22 is matched with an internal thread of a screw hole of an end cover of the speed reducer; the mounting groove 11 is matched with the screw jack base.
As shown in FIG. 3, when the utility model is used, firstly, one end of the top cover of the QL-20T type screw jack 3 is vertically fixed on the driving roller shaft 5 of the TDZA1000 type bucket elevator, and the base of the QL-20T type screw jack at the other end is vertically fixed in the mounting groove 11. Then, the fixing nut 21 is screwed by using a monkey wrench, so that the external thread 22 at the bottom end of the fixing screw rod 2 is rotationally fixed in the screw hole of the B3HH08D type reducer end cover 4, and the fixing screw rod 2 connects the fixing plate 1 and the reducer end cover together. Finally, the operator uniformly shakes the handle of the QL-20T-shaped screw jack 3 with force, under the action of the screw jack 3, the fixing plate 1 and the fixing screw rod 2 act together to pull the B3HH08D type speed reducer out of the driving roller shaft 5 of the TDZA1000 type bucket elevator, namely, the speed reducer is separated from the driving roller of the bucket elevator.
The mounting groove 11 does not penetrate through the middle of the fixing plate 1, the mounting groove 11 is circular, and the diameter of the mounting groove 11 is 140-160 mm. As the diameter of the base of the QL-20T-shaped screw jack 3 is about 140mm, the mounting groove 11 is matched with the screw jack base, and the diameter of the mounting groove 11 is equal to or slightly larger than that of the base of the screw jack 3, the screw jack base is conveniently and vertically mounted in the mounting groove 11.
The length of the fixing screw rod 2 is 460mm, the diameter of the fixing screw rod 2 is 14mm, the distance between two adjacent fixing screw rods 2 in the horizontal direction is 160mm, and the distance between two adjacent fixing screw rods 2 in the vertical direction is 240 mm. Because the screw hole pitch of two adjacent horizontal directions of B3HH08D type speed reducer end cover 4 is 160mm, the screw hole pitch of two adjacent vertical directions is 240mm, the bottom of fixed screw rod 2 is provided with external screw thread 22, external screw thread 22 and the internal thread looks adaptation of speed reducer end cover screw, conveniently fix the external screw thread 22 rotation of the bottom of fixed screw rod 2 in the screw hole of B3HH08D type speed reducer end cover 4, with speed reducer and bucket elevator drive cylinder quick separation.
