Abstract
Description
Technical Field
[0001] The utility model relates to a device for lifting a positioning pin of a bearing seat, and belongs to the technical field of bearing seat equipment in the metallurgical industry. Background Art
[0002] The bearing seat of transmission equipment is a basic component of the transmission system and is widely used in the metallurgical industry. The bearing seat is usually split, including an upper half and a lower half, which are positioned and connected together by locating pins. The locating pins play a very important role in positioning the upper and lower halves of the bearing seat. In particular, the locating pins of the bearing seat of large equipment are tightly matched. When removing the locating pins of the bearing seat, due to the tight fixation, it is often difficult to remove them smoothly, resulting in a temporary halt in maintenance. If the locating pins are removed violently, they may bend and cannot be reused. Therefore, it is urgent to invent a device that is convenient for lifting the locating pins of the bearing seat, which can quickly and conveniently remove the locating pins on the bearing seat so that maintenance can proceed smoothly. Utility Model Content
[0003] The purpose of the utility model is to provide a device for lifting the locating pin of a bearing seat, which has a simple structure and can quickly remove the locating pin on the bearing seat, thereby solving the problems existing in the background technology.
[0004] The technical solution of the utility model is:
[0005] A device for lifting the locating pin of a bearing seat comprises an upper half of the bearing seat, a locating pin and a lower half of the bearing seat. The upper half of the bearing seat and the lower half of the bearing seat are positioned and connected together by the locating pin. The composition of the device also includes a sleeve, a pressure cover, a nut and a bolt. The sleeve is placed on the upper half of the bearing seat and is sleeved on the locating pin. The pressure cover is fixed on the sleeve. The bolt passes through the pressure cover. The lower end of the bolt is fixedly connected to the locating pin. The upper end of the bolt is provided with a nut.
[0006] The diameter of the bolt matches the size of the positioning pin.
[0007] The bolt and the positioning pin are welded together, and the center lines of the bolt and the positioning pin coincide with the center line of the sleeve.
[0008] A bolt hole matched with a bolt is provided at the center of the gland.
[0009] By adopting the utility model, the nut is continuously tightened and the positioning pin is slowly screwed out until the positioning pin is completely taken out.
[0010] The beneficial effects of the utility model are: simple structure, easy use, the positioning pin on the bearing seat can be quickly removed, and maintenance is time-saving and labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] In the figure: the upper half of the bearing seat 1, the positioning pin 2, the sleeve 3, the pressure cover 4, the nut 5, the bolt 6, the lower half of the bearing seat 7, and the bolt hole 41. DETAILED DESCRIPTION
[0015] The present invention will be further described below with reference to the accompanying drawings and examples.
[0016] Refer to the attached Figure 1-3 A device for lifting the locating pin of a bearing seat comprises an upper part 1 of the bearing seat, a locating pin 2 and a lower part 7 of the bearing seat. The upper part 1 of the bearing seat and the lower part 7 of the bearing seat are positioned and connected together by the locating pin 2. The composition also includes a sleeve 3, a pressure cover 4, a nut 5 and a bolt 6. The sleeve 3 is placed on the upper part 1 of the bearing seat and is sleeved on the locating pin 2. The pressure cover 4 is fixed on the sleeve 3. The bolt 6 passes through the pressure cover 4. The lower end of the bolt 6 is fixedly connected to the locating pin 2, and the upper end of the bolt 6 is provided with a nut 5.
[0017] In this embodiment, refer to the attached Figure 1 , the sleeve 3 is placed on the plane of the upper part 1 of the bearing seat, and the locating pin 2 and the bolt 6 are covered inside. The pressure cover 4 is installed on the upper end of the sleeve 3. The bolt 6 passes through the bolt hole 41 on the pressure cover 4 and is assembled with the nut 5. Then, the nut 5 is tightened. As the nut 5 continues to be tightened, the locating pin 2 will be slowly unscrewed until the locating pin 2 is completely removed.
[0018] Refer to the attached Figure 2 The locating pin 2 is used to fix the upper half 1 of the bearing seat and the lower half 7 of the bearing seat. The diameter of the selected bolt 6 is equivalent to the diameter of the locating pin 2. The bolt 6 is welded to the locating pin 2 in an inverted manner. The sleeve 3 is made of a round tube. The sleeve 3 is slightly shorter than the total length of the welded bolt 6 and the locating pin 2, which facilitates the rapid tightening of the nut 6 until the locating pin 2 is completely unscrewed.
