Problems solved by technology

The weight of the upper bearing seat is nearly 700 kg. In the case of no external force, the upper bearing seat itself is in a static state and will not roll. Once the operator installs the snap ring and tightens the screw forcefully, a torque is applied to the upper bearing seat. It will rotate left and right under the action of a large inertia, and the two levers of the bearing seat will hit the operator's head and cause a safety accident. In the prior art, two operators need to cooperate to disassemble and clean the upper bearing seat.

Embodiment 1

[0022] Such as figure 1 As shown, a special device for anti-rotation of the bearing seat includes a cross fixing frame 1 for clamping the flat head of the rotating shaft. The cross fixing frame is made of two door-shaped metal frames 1a and 1b. A screw rod 2 is fixed on the top of the intersection of the frames (that is, the junction of the two door-shaped metal frames), and the screw rod is perpendicular to the upper end faces of the two door-shaped metal frames, and a nut 3c is sleeved on the screw rod. Both sides of the nut are fixed with a left balance bar 3a and a right balance bar 3b on the same straight line. The height of two gate-shaped metal frames 1a, 1b is 20cm.

[0023] When in use, as long as the cross bracket is clamped on the flat head of the rotating shaft, tighten the nut, and place the balance bars on both sides of the nut on the upper ends of the left and right levers, the relative rotation between the flat head of the rotating shaft and the lever can be ...

Embodiment 2

[0025] The difference from Embodiment 1 is that it also includes a three-bar pressing device 4, which is composed of three pressing bars 4b that are fixed to the rotating head 4a and form 120° with each other. The center of 4a is a threaded circular hole 4a-1, and the swivel head and the screw rod are threaded.

[0026] When in use, set the three-bar compression device on the screw rod, rotate the three-bar compression device firmly to press it tightly on the nut, and fix the nut firmly, so as to ensure that the balance bar is firmly pressed against the two levers the upper end. Thus, the safety factor is further increased, and the double insurance of safe operation is realized.

[0027] As a preferred solution, the nut is welded on the screw rod. In this case, the nut, the cross bracket and the screw rod are integrated. This scheme can also be applied in Example 1.

Abstract

The invention relates to a special device for preventing a bearing seat from rotating. The special device comprises a cross fixing bracket (1), wherein the cross fixing bracket (1) is used for clamping a flat end of a rotary shaft, the cross fixing bracket (1) is formed by fixedly connecting two door-shaped metal brackets (1a and 1b), the top end of the crossed part of the cross fixing bracket is fixedly provided with a screw rod (2), the screw rod (2) is sheathed with a nut (3c), and the two sides of the nut are fixedly provided with a left balance rod (3a) and a right balance rod (3b) which are positioned in a straight line. As the second embodiment, the special device also comprises a three-rod pressing device (4), wherein the three-rod pressing device consists of three press rods (4b), the three press rods are fixedly connected with a rotary head (4a) and mutually form 120 degrees, the center of the rotary head (4a) is provided with a circular hole (4a-1) which is provided with threads, and the rotary head is in thread connection with the screw rod. The special device has the advantage that an upper bearing seat and the flat end of the rotary shaft can be combined into a whole, so the relative rotation between the upper bearing seat and the flat end of the rotary shaft is avoided, the body safety of operators is ensured, and the occurrence of safety accidents is avoided.

Description

technical field [0001] The invention relates to a special device for preventing rotation of a bearing seat, in particular to a special device for preventing the rotation of the upper bearing seat when cleaning and installing the upper bearing seat in the grinding roller operation area. Background technique [0002] In the grinding roll operation area of ​​steel processing enterprises, cleaning and installation of bearing housings is an essential operation procedure before roll operation. Figure 4 It is a structural schematic diagram of the upper bearing seat. In the working state, the two levers 7 and 8 protruding forward from the left and right ends of the upper bearing seat are erected on the guide rail; when disassembled and cleaned, the upper bearing seat protrudes forward, The frame 5 is in a suspended state, and the middle of the bearing seat is a protruding rotating shaft flat head 6. When torque is applied, the upper bearing seat and the rotating shaft of the grindin...
