Description

Technical Field

[0001] The invention relates to the technical field of mechanical parts assembly lifting devices, and specifically provides a large-scale industrial bearing installation and lifting device. Background Art

[0002] In the field of mechanical assembly, in order to ensure assembly accuracy and coaxiality, avoid axial and radial displacement between bearings and shafts, and withstand greater loads, bearings and shafts are often assembled and installed using interference fit. Large industrial bearings are mounted on the shafts of heavy machinery and equipment, and have obvious characteristics such as large size and heavy weight.

[0003] Under the existing technology, when assembling a large bearing relative to a shaft, the shaft to be installed is often placed vertically. According to the principle of thermal expansion and contraction, the bearing will be reasonably preheated in advance to facilitate installation and reduce matching resistance before assembly, and the bearing needs to be lifted with the help of corresponding lifting equipment to align the bearing with the shaft. During the assembly process, the lifting equipment will be loosened and the bearing will slide down along the shaft by its own weight. However, during actual installation, on the one hand, the lifting equipment only plays a simple lifting role. When the lifting equipment is loosened, the inner ring of the bearing will randomly contact with the shaft when the bearing slides down, and the contact resistance is unevenly distributed in the circumferential direction. This makes the bearing prone to slight tilt and affects assembly. On the other hand, as the bearing dissipates heat quickly, the fitting resistance between the bearing and the shaft will gradually increase, and the sliding movement of the bearing will suddenly stop. At this time, the bearing is generally allowed to slide smoothly to the specified position by manual knocking. However, when manually knocked, the bearing is in a single-point force state, and the knocking points mostly act on the outer ring of the bearing. When the bearing assembly resistance is large and multiple knocks are required, it is obvious that the bearing structure will be damaged to a certain extent. For bearings assembled on mechanical equipment that requires high strength and high stability, the assembly method is inappropriate. Summary of the invention

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] like Figure 1 As shown, a large-scale industrial bearing installation lifting equipment includes a ring hanger 1, and three hook ends 12 are evenly distributed on the top circumference of the ring hanger 1. The hook ends 12 are connected to iron chains or steel cables. In this embodiment, steel cables are preferred. One end of the three steel cables can be fixedly connected to the same lifting ring, and the lifting ring can be connected to the lifting end of an existing lifting machinery. It should be emphasized that in the present invention, the lifting equipment refers to a sling that can be connected to the lifting end of an existing lifting machinery.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, three wing plate slide rails 11 are welded evenly distributed on the circumference of the circular hanger 1, and the three wing plate slide rails 11 and the three hook ends 12 are evenly and alternately distributed in the circumferential direction of the circular hanger 1, and the wing plate slide rails 11 extend radially along the circular hanger 1; the three wing plate slide rails 11 are respectively equipped with supporting side clamping mechanisms 2, and the three supporting side clamping mechanisms 2 are used to jointly support and place bearings and clamp the bearings; the supporting side clamping mechanism 2 includes an advance cylinder 21 horizontally fixed on the wing plate slide rail 11 at one end away from the center of the circular hanger 1 through a fixed plate, and a hanging slide plate 22 is slidably installed on the wing plate slide rail 11, and the hanging slide plate 22 is fixed at the output end of the advance cylinder 21, and a supporting plate 23 for supporting the bearing is horizontally welded at the bottom end of the hanging slide plate 22, and the supporting plate 23 extends to a side close to the center of the circular hanger 1, and a side clamping plate 24 for clamping and contacting the side wall of the outer ring of the bearing is vertically welded on the supporting surface of the supporting plate 23.

[0033] The bearing can be preheated by a heating device before assembly. After the preheating reaches the set temperature (the required preheating temperature is determined by actual measurement, and the appropriate preheating temperature is based on meeting the assembly requirements and not damaging the bearing structure), when the three suspended slides 22 are moved to the position farthest from the center of the ring hanger 1, the bearing is moved between the three side clamps 24 by moving the lifting device. Then, the lifting device is moved upward so that the bearing is passively overlapped on the three supporting plates 23. Subsequently, the three advance cylinders 21 are started synchronously so that the outer ring of the bearing is clamped between the three side clamps 24. The side clamps 24 not only improve the stability of the bearing lifting and support, but also provide lateral protection, thereby improving safety during the lifting process.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in order to further improve the stability of the bearing during the lifting process, the circular hanger 1 is also equipped with a pressing mechanism 3 for pressing the bearing downward; the pressing mechanism 3 includes a pressing drive assembly 31 and three pressing plate members 32 mounted on the three side clamping plates 24 in a one-to-one correspondence, the pressing drive assembly 31 includes a circular frame lifting frame 311 coaxially arranged with the circular hanger 1, the circular frame lifting frame 311 is located below the circular hanger 1, and three guide pillars 312 are evenly distributed on the top circumference of the circular frame lifting frame 311. The three guide pillars 312 are vertically slidably mounted on the circular hanger 1, and the bottom end of the circular frame lifting frame 311 Three sliding feet 313 are evenly distributed and welded on the circumference and are connected to the three pressure plate members 32 in a one-to-one manner; a lifting cylinder (not shown in the figure) can be fixedly installed on the top of the circular ring hanger 1, and the circular frame lifting frame 311 can be fixed on the output end of the lifting cylinder, and the circular frame lifting frame 311 can be driven to rise and fall by the lifting cylinder; a radial slide rail 321 extending radially along the circular ring hanger 1 is welded on the top of the pressure plate member 32, and the sliding feet 313 are slidably docked on the radial slide rail 321, and a slide groove 241 is opened on the side clamp 24 from the top downward, and a vertical slide 322 that slidably cooperates with the slide groove 241 is provided on the pressure plate member 32.

[0035] After the bearing is supported and side clamped by the three supporting side clamping mechanisms 2, the circular frame lifting frame 311 is driven down by the lifting cylinder, and then the three pressure plates 32 are driven down synchronously and pressed on the upper end of the bearing. Then the bearing is restricted between the three side clamping plates 24 and is in an up and down clamping state. When the lifting equipment is in a suspended state, the bearing can be better in a horizontal and stable state, thereby effectively suppressing the tilt during assembly. It should be supplemented that when the bearing is in a side clamping and up and down clamping state, the supporting plate 23 and the pressure plate 32 do not extend to the inner ring hole of the bearing, but both are in contact with the outer ring and inner ring of the bearing at the same time to ensure the overall force of the outer ring and inner ring of the bearing.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 8 and Fig. 9As shown, a pressing mechanism 4 is installed on the pressing mechanism 3 to push the bearing to move along the axis. The pressing mechanism 4 includes three pressing assemblies 41 which are assembled on the pressing plate 32 in a one-to-one correspondence and a pushing drive assembly 42 which synchronously drives the three pressing assemblies 41. An open guide groove 323 is vertically penetrated on the pressing plate portion of the pressing plate 32. The pressing assembly 41 includes a pushing block 414 which is vertically slidably mounted in the open guide groove 323. The pressing assembly 41 also includes a base plate 411 located above the pressing plate 32. Two No. 1 springs 415 are vertically welded between the base plate 411 and the pressing plate 32. Two guide rods 413 are vertically welded at the bottom end of the base plate 411. The pushing block 414 is slidably mounted on the two guide rods 413 through the guide rod holes opened at the top. A No. 2 spring 416 is sleeved on the guide rod 413, and the two ends of the No. 2 spring 416 are respectively welded. It is connected to the base plate 411 and the propulsion block 414; the propulsion drive assembly 42 includes a slewing bearing 421 coaxially arranged and welded in the round frame of the round frame lifting frame 311, and a driving motor 424 vertically fixed to the round frame lifting frame 311 by bolts, a driving gear 425 is fixed to the output shaft of the driving motor 424, and a driven gear ring 422 meshing with the driving gear 425 is welded to the top of the inner ring of the slewing bearing 421; a driving ring 423 is coaxially arranged and horizontally welded to the bottom end of the inner ring of the slewing bearing 421, and the lower end face of the driving ring 423 is an annular concave-convex surface with uniform and alternating undulations, and a ball 412 is movably installed on the top of the base plate 411. Under the elastic force of the No. 1 spring 415, the ball 412 rolls in contact with the annular concave-convex surface of the driving ring 423. The pressing and pushing mechanism 4 is lifted and lowered synchronously with the circular frame lifting frame 311. In the present embodiment, when the ball 412 contacts the most concave part of the annular concave-convex surface of the driving ring 423, the lower end surface of the pushing pressure block 414 is not exposed relative to the lower end of the opening guide groove 323 and is in a basically flush position. In addition, it should be supplemented that the lower end surface of the pushing pressure block 414 can be pressed and contacted with the inner and outer rings of the bearing at the same time, and the pushing pressure block 414 can also avoid the inner ring hole area of ​​the bearing.

[0037] When the bearing is pressed up and down, the bearing is lifted by the lifting equipment and moved to the top of the shaft to be assembled, and the height of the bearing is continuously lowered so that the inner ring hole of the bearing is aligned with the shaft, and then it continues to descend so that the shaft passively passes through the bearing under the action of gravity. Then, the drive motor 424 is started, and the driven gear ring 422 is driven by the drive gear 425, so that the drive ring 423 rotates with the driven gear ring 422, and the ball 412 rolls relatively along the annular concave and convex surface of the drive ring 423. When the ball 412 rolls from the most concave part to the most convex part of the annular concave and convex surface, the base plate 411 gradually descends, and the No. 1 spring 415 is gradually compressed, pushing the pressure block 414 As the base plate 411 descends, it has a tendency to slide out from the open guide groove 323, but since the bearing is stably clamped between the pressure plate 32 and the support plate 23, the push block 414 cannot actually slide out, but the No. 2 spring 416 is gradually compressed, and the pressure of the push block 414 on the upper end of the bearing gradually increases. Correspondingly, when the ball 412 rolls from the most convex part to the most concave part of the annular concave-convex surface, the pressure of the push block 414 on the upper end of the bearing gradually decreases. Since the annular concave-convex surface is evenly undulating, the three base plates 411 are raised and lowered synchronously, and then the three push assemblies 41 form three circumferentially evenly distributed reciprocating downward thrusts on the upper end of the bearing.

[0038] During the assembly process, the lifting end of the lifting device is gradually relaxed. When in a relaxed state, under the action of gravity, the lifting device and the bearing have a tendency to move downward. Therefore, through the continuous reciprocating downward pressure of the press-in thrust mechanism 4, the bearing is pressed and slid along the shaft, and the lifting end tends to be tightened again, and then relaxed again, and tightened again. Through the step-by-step descent of the lifting end, the bearing is continuously and stably pressed in until the bearing moves to the shaft shoulder assembly position; during the press-in assembly process, the bearing is continuously pressed in through multiple evenly distributed and continuously reciprocating downward thrusts, avoiding the single-point impact force on the bearing caused by the knocking method, better protecting the bearing's own structure, and the step-by-step tightening effect can actively adjust the bearing's pressed posture to avoid the bearing assembly tilt, thereby better realizing the smooth, fast and smooth installation of the bearing.

[0039] After the assembly is completed, the pressing plate 32 and the supporting side clamping mechanism 2 are loosened, and the lifting device is moved out.
