Description

Technical Field

[0001] This utility model relates to a mounting and fixing assembly for the front cover of an excavator turntable, belonging to the field of excavator technology. Background Technology

[0002] Excavators are heavy machinery widely used in construction, mining, and civil engineering. Their main function is to dig, transport, and shovel soil using buckets and other devices. Modern excavator technology involves multiple aspects, including hydraulic systems, engine technology, and electronic control systems. Hydraulic systems provide powerful support and enable precise motion control; engine technology determines the excavator's working efficiency and power output; and electronic control systems improve operational safety and accuracy through intelligent management. Furthermore, with the development of automation and intelligent technologies, excavators are gradually moving towards unmanned driving and remote control, further enhancing work efficiency and safety.

[0003] Authorization announcement number (CN218622383U) discloses an excavator turntable, including a base, a frustum fixedly mounted on the base, a mounting seat fitted onto the upper end of the frustum, a buffer groove formed in the bottom wall of the mounting seat, a rotary bearing fixedly mounted on the side wall of the frustum, the inner wall of the buffer groove slidably mounted on the outer wall of the rotary bearing, a first rotating groove formed on the upper surface of the frustum, and a second rotating groove penetrating the bottom of the frustum formed on the bottom wall of the first rotating groove. This utility model achieves excavator rotation through a planetary gear structure, resulting in a more stable and less labor-intensive operation with a centered axis, reducing drive energy consumption. Through spring buffering and air pressure throttling to release buffer energy, it effectively reduces the amplitude and frequency of swaying, improving the excavator's shock resistance and enhancing the riding experience.

[0004] In summary, the lack of a front cover fixing assembly on the excavator's turntable can lead to the front cover not being stably secured to the turntable, thus affecting the overall structural stability and safety of the excavator. The front cover fixing assembly is typically used to connect the front cover to the turntable, preventing it from loosening or detaching during operation due to vibration or other external forces. The absence of this crucial fixing assembly can cause machine malfunctions and even compromise operator safety. Therefore, the proper design and installation of a front cover fixing assembly is an important measure to ensure the efficient and safe operation of excavators.

[0005] To address this, a mounting and fixing assembly for the front cover of an excavator turntable is proposed. Utility Model Content

[0006] In view of this, the present invention provides an excavator turntable front cover mounting and fixing component to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is implemented as follows: A front cover mounting and fixing assembly for an excavator turntable includes a base, an outer ring fixedly mounted on the top of the base, and a mounting assembly provided at the bottom of the outer ring. The mounting assembly includes a front cover body, which is fixedly mounted on the bottom of the outer ring. A fixing plate is fixedly mounted around the top of the front cover body. A pull rod is slidably connected to the inner side of the fixing plate. A buckle is fixedly mounted on the right side of the pull rod, and the right end of the buckle is trapezoidal. A second spring is sleeved on the surface of the pull rod.

[0008] More preferably, a fixing strip is fixedly installed around the bottom of the outer ring, an upper ring is slidably connected to the surface of the fixing strip, a lower ring is fixedly installed at the bottom of the fixing strip, a first spring is sleeved on the surface of the fixing strip and located at the bottom of the fixing plate, and the buckle passes through the fixing plate and extends between the upper and lower rings.

[0009] More preferably, a cooling component is provided at the bottom of the base. The cooling component includes a housing, which is fixedly installed at the bottom of the base. A fan is fixedly installed on the inner side of the housing, and a cooling rod is fixedly installed on the inner side of the housing and at the bottom of the fan.

[0010] More preferably, the bottom of the housing has a ventilation opening that extends through the base and to the top of the base.

[0011] More preferably, U-shaped grooves are fixedly installed on the left and right sides of the bottom of the box, and a filter screen is slidably connected to the inner side of the U-shaped groove.

[0012] More preferably, an inner ring is movably connected to the top of the base and to the inside of the outer ring, and the surface of the inner ring is distributed with a plurality of teeth.

[0013] More preferably, a mounting base is fixedly installed on the top of the base on the inner side of the inner ring, and a slot is formed on the inner side of the mounting base.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] I. This utility model uses the lower ring to press the buckle, causing the buckle to move inward towards the fixed plate. At this time, the second spring is compressed and deformed. When the buckle reaches between the lower and upper rings, the second spring loses pressure, causing the buckle to return to its original position and engage between the lower and upper rings. This effectively ensures that the front cover body is stably connected to the turntable, thereby enhancing the structural stability of the entire machine, resisting vibrations and external forces generated during operation, preventing the front cover from loosening or falling off, and reducing the risk of malfunctions.

[0016] II. This utility model, by starting the fan, draws outside air into the housing through the filter screen. The cooling rod converts the air into cold air, which is then transmitted to the inner side of the inner ring through the vent. This effectively prevents the turntable system from overheating, ensures the stability of the hydraulic system and engine under high load, extends the service life of the equipment, and improves operating efficiency.

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1-4 As shown, this utility model embodiment provides an excavator turntable front cover mounting and fixing assembly, including a base 1, an outer ring 2 fixedly mounted on the top of the base 1, and a mounting assembly 5 provided at the bottom of the outer ring 2. The mounting assembly 5 includes a front cover body 501, which is fixedly mounted on the bottom of the outer ring 2. A fixing plate 502 is fixedly mounted around the top of the front cover body 501. A pull rod 507 is slidably connected to the inner side of the fixing plate 502. A buckle 509 is fixedly mounted on the right side of the pull rod 507, and the right end of the buckle 509 is trapezoidal. A second spring 506 is sleeved on the surface of the pull rod 507.

[0029] The lower ring 503 presses against the buckle 509, causing the buckle 509 to move inward toward the fixed plate 502. At this time, the second spring 506 is compressed and deformed. When the buckle 509 reaches between the lower ring 503 and the upper ring 508, the second spring 506 loses pressure, causing the buckle 509 to return to its original position and engage between the lower ring 503 and the upper ring 508. This effectively ensures that the front cover is securely connected to the turntable, thereby enhancing the structural stability of the entire machine, resisting vibrations and external forces generated during operation, preventing the front cover from loosening or falling off, and reducing the risk of malfunctions.

[0030] Example 2

[0031] like Figure 1-5As shown, in one embodiment, a fixing strip 505 is fixedly installed around the bottom of the outer ring 2. An upper ring 508 is slidably connected to the surface of the fixing strip 505, and a lower ring 503 is fixedly installed at the bottom of the fixing strip 505. A first spring 504 is sleeved on the surface of the fixing strip 505 and located at the bottom of the fixing plate 502. A buckle 509 passes through the fixing plate 502 and extends between the upper ring 508 and the lower ring 503. A cooling component 6 is provided at the bottom of the base 1. The cooling component 6 includes a housing 601, which is fixedly installed at the bottom of the base 1. A cooling component 504 is fixedly installed on the inner side of the housing 601. A cooling rod 603 is fixedly installed inside the fan 602 and at the bottom of the housing 601. A vent 604 is opened at the bottom of the housing 601, which passes through the base 1 and extends to the top of the base 1. U-shaped grooves 605 are fixedly installed on the left and right sides of the bottom of the housing 601. A filter screen 606 is slidably connected to the inside of the U-shaped groove 605. An inner ring 3 is movably connected to the top of the base 1 and inside the outer ring 2. Multiple teeth are distributed on the surface of the inner ring 3. A mounting base 4 is fixedly installed on the top of the base 1 and inside the inner ring 3. A slot 7 is opened on the inside of the mounting base 4.

[0032] By starting the fan 602, the fan 602 draws outside air into the housing 601 through the filter 606. The air is then converted into cold air by the cooling rod 603 and transmitted to the inside of the inner ring 3 through the vent 604. This effectively prevents the turntable system from overheating, ensures the stability of the hydraulic system and engine under high load, extends the service life of the equipment, and improves operating efficiency.

[0033] In operation, this invention first presses the buckle 509 by the lower ring 503, causing the buckle 509 to move inward toward the fixed plate 502. At this time, the second spring 506 is compressed and deformed. When the buckle 509 reaches between the lower ring 503 and the upper ring 508, the second spring 506 loses pressure, causing the buckle 509 to return to its original position and engage between the lower ring 503 and the upper ring 508. This effectively ensures that the front cover is securely connected to the turntable, thereby enhancing the structural stability of the entire machine, resisting vibrations and external forces generated during operation, preventing the front cover from loosening or falling off, and reducing the risk of malfunctions. When the turntable is working, the fan 602 is started, drawing outside air into the housing 601 through the filter 606. The cooling rod 603 converts the air into cold air, which is then transmitted to the inner side of the inner ring 3 through the vent 604. This effectively prevents the turntable system from overheating, ensures the stability of the hydraulic system and engine under high load, extends the service life of the equipment, and improves operating efficiency.

[0034] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
