DETAILED DESCRIPTION

[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings of the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0027] Embodiment 1

[0028] Reference Figures 1-4The utility model provides a device for installing plane bearing conveniently, which is applied in the technical field of bearing installation and comprises a bottom plate 1 made of high-strength steel to ensure stability. An installation part is arranged on the upper side of the bottom plate 1, which is composed of a vertical plate 2 and a top plate 3. The vertical plate 2 is vertically fixed to the top end of the bottom plate 1, and the top plate 3 is horizontally fixed to the side end of the vertical plate 2. A hydraulic oil cylinder 4 is installed at the top end of the top plate 3 to provide power.

[0029] The output end of the hydraulic oil cylinder 4 is fixedly connected with an extrusion rod 5, which is designed in a hollow structure and internally provided with a first groove 13. A positioning disc 6 is fixed to the surface of the extrusion rod 5 near the bottom position thereof to preliminarily position a cover plate 7.

[0030] A cross lifting plate 14 is installed in the first groove 13 and is slidably connected with four sliding grooves 16 and four sliding blocks 21. The top end of each sliding block 21 is fixed with a clamping plate 15, which is used to clamp the cover plate 7. Meanwhile, a lifting screw 19 is arranged in the first groove 13 and is threadedly connected with the cross lifting plate 14. The cross lifting plate 14 can be driven to move up and down by rotating the lifting screw 19, thereby driving the clamping plates 15 to clamp or release the cover plate 7.

[0031] Each set of guiding components comprises a guiding rod 17 fixed in the clamping plate 15 and penetrating through two guiding grooves 18 formed in the extrusion rod 5. The driving motor 20 is started to drive the lifting screw 19 to rotate, which drives the cross lifting plate 14 to move up. When the cross lifting plate 14 moves up, the four clamping plates 15 are synchronously lifted, which drives the four guiding rods 17 to move up. The four guiding rods 17 are guided to relatively displace by the guiding grooves 18, and the four clamping plates 15 are guided to relatively displace outward by the four guiding rods 17, thereby moving out of the first groove 13. When the cross lifting plate 14 is lifted by the lifting screw 19, the clamping plates 15 reach the bottom end of the cover plate 7, which is clamped and fixed by the positioning disc 6. The extrusion rod 5 is lowered by starting the hydraulic oil cylinder 4 to complete the installation of the cover plate 7. After installation, the driving motor 20 is reversed to drive the clamping plates 15 to move downward and return to the first groove 13. The extrusion rod 5 is lifted by the hydraulic oil cylinder 4 to complete the installation.

[0032] Anti-skid pads are arranged at the bottom end of the positioning disc 6 and the top end of the four clamping plates 15 to enhance the clamping force and prevent the cover plate 7 from sliding. In addition, the surface of the extrusion rod 5 is processed with external threads and is threadedly connected with a limiting ring 12. The position of the limiting ring 12 can be adjusted to centrally limit the cover plate 7.

[0033] Embodiment 2

[0034] Reference Figures 1-4On the basis of embodiment 1, the top end of the bottom plate 1 is also provided with a threaded groove 10, a bolt 11 is threadedly connected in the threaded groove 10, and the top end of the bolt 11 is fixed with a positioning ring 9 for centrally limiting the stationary part 8 and ensuring the stability of the stationary part 8 during installation.

[0035] However, as known by those skilled in the art, the working principle and wiring method of the driving motor 20 and the hydraulic cylinder 4 are common, which belong to conventional means or common general knowledge, and will not be described herein, and those skilled in the art can make any selection according to needs or convenience.

[0036] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
