Description

Technical Field

[0001] This utility model relates to the field of hanging bracket technology, and in particular to a heavy-duty bushing hanging bracket. Background Technology

[0002] A hanger is a mechanical structural component used to suspend, support, and position specific parts. Its core function is to stably connect the target load to the base through "suspension" while bearing the weight, vibration, impact, and other forces of the load, and ensuring the installation accuracy and operational stability of the suspended parts. As the core load-bearing and fixing structure of the bushing, the heavy-duty bushing hanger needs to withstand the longitudinal load, radial impact force, and vibration load generated during equipment operation transmitted by the bushing for a long time.

[0003] To address this, patent CN207632328U discloses a heavy-duty bushing hanger, comprising a cylinder for mounting the bushing, a front plate and a rear plate respectively fitted onto the front and rear ends of the cylinder, and a left vertical plate and a right vertical plate respectively located on the left and right sides of the cylinder. The front and rear plates are welded to the cylinder. The left vertical plate is fitted and welded to the left edge of both the front and rear plates, and the right vertical plate is fitted and welded to the right edge of both the front and rear plates. The front and rear plates, viewed from the front, form approximately inverted isosceles triangles. Stress relief holes are provided on the front, rear, left, and right vertical plates, and their top surfaces are all on the same welding plane. This hanger can absorb some stress through its own deformation, exhibiting good deformation capacity, strong adaptability, uniform stress distribution, and light weight.

[0004] The heavy-duty bushing hanger mentioned above requires repeated adjustments to the relative position of the hanger and the external equipment using external measuring tools during assembly to ensure the coaxiality of the bushing. This not only increases assembly time but also makes the bushing installation prone to misalignment due to human error, affecting the operating accuracy of the equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a heavy-duty bushing hanger to solve the problem that existing heavy-duty bushing hangers are inconvenient to install.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a heavy-duty bushing hanger, including a fixed base;

[0007] A support base is fixed to the bottom of the fixed base. The support base has an internal shaft hole. Protective structures are fixed to both sides of the fixed base. The protective structures include a first connecting plate fixed to both sides of the fixed base. A second connecting plate is fixed to both sides of the fixed base on one side of the first connecting plate.

[0008] The mounting structure includes a first through hole disposed inside the first connecting plate and the second connecting plate. A connecting seat is fixed to one side of the fixing seat. A fixing groove is disposed on the bottom side of the connecting seat. A mounting plate is installed at the bottom end of the connecting seat. Mounting holes are disposed on both sides inside the mounting plate. A fixing block is fixed to the top of the mounting plate. Fixing plates are fixed to both sides of the top of the mounting plate. A second through hole is disposed inside the fixing plate. Bolts are installed inside the first through hole and the second through hole. Washers are installed on both sides of the first connecting plate and the second connecting plate outside the bolts.

[0009] Preferably, a reinforcing rib is fixed to the front side of the fixing seat on one side of the first connecting plate, a dustproof ring is fixed to both ends of the shaft holes on both sides of the support seat, an arc-shaped groove is provided on both sides of the top of the fixing seat, a triangular rib is fixed to the bottom of the reinforcing rib, and a sloping groove is provided on both sides of the bottom of the fixing seat.

[0010] Preferably, the first connecting plate and the second connecting plate are symmetrically distributed on both sides of the fixed base, and the bottom side of the support base is semi-circular.

[0011] With the above structure, the semi-circular structure on the bottom side of the support seat allows the load transmitted by the bushing to be evenly distributed along the arc-shaped surface at the bottom of the support seat during use, avoiding the load being concentrated on the sharp edge at the bottom of the support seat.

[0012] Preferably, the dustproof ring is made of nitrile rubber, the arc-shaped grooves are symmetrically distributed at the top of the fixing base, and one side of the triangular rib is fixedly connected to one side of the inclined groove.

[0013] With the above structure, the nitrile rubber material has excellent sealing performance during use, which can closely fit the fit gap between the two ends of the shaft hole and the bushing, effectively preventing dust, iron filings, oil and other impurities from entering the bushing. The fixed connection between the triangular rib and the inclined groove can further constrain the deformation direction of the fixed seat and enhance the deformation resistance of the fixed seat in the longitudinal and transverse directions.

[0014] Preferably, the inner side of the fixing groove fits into the outer side of the fixing block, and the fixing plates are symmetrically distributed at the top of the mounting plate.

[0015] With the above structure, the fixing slot and fixing block can be fitted together to form a preliminary connection between the fixing seat and the mounting plate before the bolts are tightened, thus avoiding the fixing seat from shaking during assembly.

[0016] Preferably, the first through hole and the second through hole correspond one-to-one, and the first connecting plate and the second connecting plate are respectively fixedly connected to the fixing plate by bolts.

[0017] With the above structure, the bolted connection allows for the removal of bolts during use, separating the connecting plate from the fixing plate, and then inspecting and replacing components such as the fixing seat and bushing.

[0018] The advantages of the heavy-duty bushing hanger provided by this utility model are as follows:

[0019] With the protective structure, the first and second connecting plates are symmetrically distributed and reinforced with ribs and triangular ribs, which can disperse the heavy load borne by the fixed seat in both the lateral and longitudinal directions. The dust rings at both ends of the shaft hole are made of oil-resistant and wear-resistant nitrile rubber, which can effectively prevent dust, iron filings and other impurities from entering the bushing fit gap.

[0020] With an installation structure, the fixing groove on the bottom of the connector and the fixing block on the top of the mounting plate are designed to fit together in a concave-convex manner. This allows for quick horizontal and vertical positioning of the fixing seat during the initial assembly stage. The first and second through holes correspond one-to-one, ensuring that the bolts can be accurately inserted and evenly stressed. The detachable connection structure achieved through the bolts not only ensures the connection strength between the fixing seat and the mounting plate and can stably transmit heavy loads, but also provides convenience for subsequent maintenance.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 The present invention provides a heavy-duty bushing hanger, including a fixed base 1.

[0029] Reference Figure 1 , Figure 2 and Figure 5 As shown, a support base 2 is fixed to the bottom of the fixed base 1. The support base 2 has an internal shaft hole 3. Protective structures 4 are fixed to both sides of the fixed base 1. Each protective structure 4 includes a first connecting plate 401 fixed to both sides of the fixed base 1. A second connecting plate 402 is fixed to both sides of the fixed base 1 on one side of the first connecting plate 401. A reinforcing rib 403 is fixed to the front side of the fixed base 1 on one side of the first connecting plate 401. Dustproof rings 404 are fixed to both ends of the shaft holes 3 on both sides of the support base 2. Both sides of the top are provided with arc-shaped grooves 405, and the bottom of the reinforcing ribs 403 are fixed with triangular ribs 406. Both sides of the bottom of the fixing base 1 are provided with inclined grooves 407. The first connecting plate 401 and the second connecting plate 402 are symmetrically distributed on both sides of the fixing base 1. The bottom side of the support base 2 is semi-circular. The dustproof ring 404 is made of nitrile rubber. The arc-shaped grooves 405 are symmetrically distributed at the top of the fixing base 1. One side of the triangular ribs 406 is fixedly connected to one side of the inclined grooves 407.

[0030] The first connecting plate 401 and the second connecting plate 402 on both sides of the fixed seat 1 are symmetrically distributed and rigidly connected to the fixed seat 1, converting part of the longitudinal load borne by the fixed seat into a lateral dispersed force, thereby improving the bending and torsional resistance of the overall structure. The reinforcing rib 403 on the front side of the fixed seat 1 on one side of the first connecting plate 401, and the triangular rib 406 fixed at the bottom end of the reinforcing rib 403, form a "triangular support" structure. One side of the triangular rib 406 is fixedly connected to the inclined groove 407 at the bottom end of the fixed seat 1, further filling the structural gap between the fixed seat 1 and the connecting plate, enhancing the rigidity of the connection part, and preventing cracks or loosening at the connection between the connecting plate and the fixed seat due to heavy load. The arc grooves 405 on both sides of the top of the fixed seat 1 prevent local wear caused by sharp contact surfaces, thus protecting the contact surface at the top of the fixed seat. At the same time, the dustproof rings 404 fixed at both ends of the shaft hole 3 can effectively block external dust and impurities from entering the fit gap between the bushing and the shaft hole, reducing wear during the operation of the bushing, extending the service life of the bushing, and ensuring the stable operation of the bushing under heavy load conditions.

[0031] Reference Figures 1-4 As shown, the mounting structure 5 includes a first through hole 501 disposed inside the first connecting plate 401 and the second connecting plate 402. A connecting seat 502 is fixed to one side of the fixing seat 1. A fixing groove 503 is provided on the bottom side of the connecting seat 502. A mounting plate 504 is installed at the bottom end of the connecting seat 502. Mounting holes 505 are provided on both sides inside the mounting plate 504. A fixing block 506 is fixed to the top end of the mounting plate 504. Fixing plates 507 are fixed to both sides of the top end of the mounting plate 504. A second through hole 507 is provided inside the fixing plate 507. Bolts 509 are installed inside the first through hole 501 and the second through hole 508. Washers 510 are installed on both sides of the first connecting plate 401 and the second connecting plate 402 outside the bolts 509. The inner side of the fixing groove 503 fits into the outer side of the fixing block 506. The fixing plates 507 are symmetrically distributed at the top of the mounting plate 504. The first through hole 501 and the second through hole 508 correspond one-to-one. The first connecting plate 401 and the second connecting plate 402 are fixedly connected to the fixing plate 507 by bolts 509.

[0032] The fixing groove 503 on the bottom side of the connecting seat 502 and the fixing block 506 on the top of the mounting plate 504 engage with each other. This interlocking structure allows for quick lateral and longitudinal pre-positioning of the fixing seat 1, preventing misalignment during installation and improving assembly efficiency. During assembly, bolts 509 are passed through the first through hole 501 and the second through hole 508 in sequence. At this time, the washers 510 on the outside of the bolts 509 adhere to both sides of the first connecting plate 401 and the second connecting plate 402, enhancing the anti-loosening effect of the bolt connection. After tightening the bolts 509, the fixing seat 1 is firmly fixed to the mounting plate 504. The mounting holes 505 on both sides of the mounting plate 504 can be used to connect to external equipment, ultimately achieving stable assembly of the entire hanging seat with the external equipment. This ensures the connection strength after assembly and facilitates subsequent disassembly and maintenance.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
