Description

Technical Field

[0001] This utility model relates to the field of excavator technology, and in particular to a slewing platform support and an excavator. Background Technology

[0002] In order to facilitate digging at any location in the working environment, the excavator body is set to rotate during use, and the slewing platform in the slewing support device bears the weight of the entire upper part of the mining excavator.

[0003] Traditional slewing platform supports are mounted on the excavator chassis, with the other side of the support connected to the slewing platform. The slewing platform bears the weight of the entire excavator body and boom. During operation, the platform support motor rotates, causing the gear ring to drive the rotation of the entire platform and body. However, in actual operation, it has been found that the support structure is only connected to the platform via the gear ring, resulting in excessively concentrated stress on the support structure. Given the overall weight of the excavator body, this can lead to overload damage to the support structure, affecting its normal use and posing certain safety hazards. Utility Model Content

[0004] This utility model addresses the problem that the connection between the support structure and the platform is solely through a toothed ring component, resulting in excessively concentrated stress on the support structure. Given the overall weight of the machine, this can lead to overload damage to the support structure, affecting its normal use and posing certain safety hazards. Therefore, this utility model proposes a rotary platform support and excavator.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a rotary platform support and an excavator, including a support plate, characterized in that: an assembly ring is fixedly connected to the surface of the support plate, a gear ring is rotatably connected to the arc surface of the assembly ring, a motor is fixedly connected to one side surface of the support plate, a gear is fixedly connected to the output end of the motor, the gear meshes with the gear ring, a support device is provided on the surface of the support plate, the support device includes a connecting ring, a plurality of evenly distributed support plates are fixedly connected to the arc surface of the connecting ring, a rotating shaft is fixedly connected to one side surface of each of the support plates, bearings are fixedly connected to the arc surfaces of both ends of the rotating shaft, the inner ring of the bearing is fixedly connected to the arc surface of the rotating shaft, the outer ring of the bearing is fixedly connected to the inner wall of the support plate, a roller is rotatably connected to the arc surface of the rotating shaft, and a slide rail is fixedly connected to the surface of the support plate, the roller is rollingly connected to the inner wall of the slide rail.

[0006] The aforementioned components achieve the following effects: when the rotating platform on one side of the machine body rotates under the drive of the support structure, it can better ensure stability, and is less likely to be damaged due to excessive pressure on the support structure caused by the excessive weight of the machine body, which would affect the normal use of the rotating platform support. It also ensures that the machine body is not prone to shaking or even breaking from the bottom, thus ensuring the effectiveness and safety of the rotating platform support.

[0007] Preferably, a reinforcing plate is fixedly connected to one side surface of each of the support plates, and a sliding groove is formed on one side surface of the slide rail, with the reinforcing plate slidably connected to the inner wall of the sliding groove.

[0008] The effect achieved by the above components is that by setting the reinforcing plate, the connection between the support plate and the slide rail is further improved, thereby making the position of the support plate more stable and ensuring the stable rotation of the excavator body.

[0009] Preferably, reinforcing rings, which are rubber rings, are fixedly connected to the arc surface of the roller.

[0010] The effect achieved by the above components is that, by setting the reinforcing ring, the friction is further increased when the roller rolls in the inner wall of the slide rail, thereby making the rotation of the support plate more stable and improving the support strength.

[0011] Preferably, a stabilizing groove is formed on one side surface of each of the plurality of support plates, and a stabilizing ring is slidably connected to the inner wall of the stabilizing groove.

[0012] The effect achieved by the above components is that, through the sliding arrangement of the stabilizing ring and the stabilizing groove, the support plate can maintain stability better when rotating, thereby providing better support for the fuselage.

[0013] Preferably, an auxiliary device is provided on one side surface of the support plate. The auxiliary device includes a rotating rod that is rotatably connected to the surface of the support plate. A brush roller is fixedly connected to one end of the rotating rod. Pulleys are fixedly connected to one end of the rotating rod and the arc surface of the output end of the motor, respectively. A connecting belt is provided on the arc surface of the pulley.

[0014] The effect achieved by the above components is to clean the surface of the ring gear, prevent foreign objects from adhering to the meshing surface, thus avoiding affecting normal meshing and rotation, and ensuring the normal use of the rotary platform support.

[0015] Preferably, one end of the rotating rod is rotatably connected to an auxiliary plate, and the auxiliary plate is fixedly connected to the surface of the support plate.

[0016] The effect achieved by the above components is that, through the setting of the auxiliary plate, the rotating rod can be better stabilized under the drive of the motor, and is less prone to shaking, thereby better cleaning the gear ring and gear.

[0017] Preferably, a scraper is fixedly connected to the surface of the support plate, and the scraper is slidably connected to the surface of the brush roller.

[0018] The effect achieved by the above components is that, through the setting of the scraper, when the brush roller cleans the surface of the toothed ring and gear, the scraper can remove the dirt and impurities attached to the brush roller, thus ensuring the cleaning effect of the brush roller.

[0019] Preferably, the excavator employs the slewing platform support as described in any one of the claims.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] When the rotating platform on one side of the machine body rotates under the drive of the support structure, it can better ensure stability and is less likely to be damaged due to excessive pressure on the support structure caused by the excessive weight of the machine body, which would affect the normal use of the rotating platform support. It also ensures that the machine body is not prone to shaking or even breaking from the bottom, thus ensuring the effectiveness and safety of the rotating platform support.

[0027] Reference Figure 1As shown, this embodiment discloses a rotary platform support and an excavator, including a support plate 1. An assembly ring 2 is fixedly connected to the surface of the support plate 1. A toothed ring 3 is rotatably connected to the arc surface of the assembly ring 2. A motor 4 is fixedly connected to one side surface of the support plate 1. A gear 5 is fixedly connected to the output end of the motor 4. The gear 5 meshes with the toothed ring 3. A support device 6 is provided on the surface of the support plate 1. An auxiliary device 7 is provided on one side surface of the support plate 1.

[0028] Reference Figure 1 and Figure 2 as well as Figure 3 As shown, this embodiment discloses a support device 6 including a connecting ring 64. A plurality of evenly distributed support plates 61 are fixedly connected to the arc surface of the connecting ring 64. A rotating shaft 62 is fixedly connected to one side surface of each of the support plates 61. Bearings 66 are fixedly connected to the arc surfaces of both ends of the rotating shaft 62. The inner ring of the bearing 66 is fixedly connected to the arc surface of the rotating shaft 62, and the outer ring of the bearing 66 is fixedly connected to the inner wall of the support plate 61. A roller 63 is rotatably connected to the arc surface of the rotating shaft 62. A slide rail 65 is fixedly connected to the surface of the support plate 1. The roller 63 is tactilely connected to the inner wall of the slide rail 65. When the excavator is in operation, the slewing platform of the machine body rotates using the slewing bracket on the chassis. At this time, the support plate 1 is activated. The motor 4 on the side drives the gear 5 to rotate, causing the gear ring 3 to rotate under the limiting position of the assembly ring 2 on the surface of the support plate 1. At this time, the support plate 61 will rotate with the rotary platform plate, causing the roller 63 on one side of the support plate 61 to roll. The roller 63 connected to the rotating shaft 62 rolls on the inner wall of the slide rail 65 on the surface of the support plate 1. When the rotary platform on one side of the machine body rotates under the drive of the support structure, it can better ensure stability and is less likely to be damaged due to excessive pressure on the support structure caused by the excessive weight of the machine body, which would affect the normal use of the rotary platform support. It also ensures that the machine body is not prone to shaking or even breaking at the bottom, thus ensuring the use effect and safety of the rotary platform support.

[0029] Reference Figure 1 and Figure 2 as well as Figure 3As shown, this embodiment discloses that a plurality of support plates 61 are fixedly connected to one side surface of each of the support plates 61, and a slide rail 65 is provided with a slide groove 611 on one side surface. The reinforcement plate 610 is slidably connected to the inner wall of the slide groove 611. By setting the reinforcement plate 610, the connection between the support plate 61 and the slide rail 65 is further improved, thereby making the position of the support plate 61 more stable and ensuring the stable rotation of the excavator body. A reinforcing ring 67 is fixedly connected to the arc surface of the roller 63. The reinforcing ring 67 is a rubber ring. By setting the reinforcing ring 67, the friction force is further increased when the roller 63 rolls in the inner wall of the slide rail 65, thereby making the rotation of the support plate 61 more stable and improving the support strength. A stabilizing groove 69 is provided on one side surface of each of the support plates 61, and a stabilizing ring 68 is slidably connected to the inner wall of the stabilizing groove 69. By sliding the stabilizing ring 68 and the stabilizing groove 69, the support plate 61 can better maintain stability when rotating, thereby better supporting the machine body.

[0030] Reference Figure 1 and Figure 2 as well as Figure 4 As shown, this embodiment discloses an auxiliary device 7 including a rotating rod 71, which is rotatably connected to the surface of the support plate 1. A brush roller 74 is fixedly connected to one end of the rotating rod 71. A pulley 72 is fixedly connected to the arc surface of one end of the rotating rod 71 and the output end of the motor 4, respectively. A connecting belt 73 is provided on the arc surface of the pulley 72. When the slewing support on the chassis supports the excavator platform, the motor 4 will rotate. Because the rotating rod 71 is connected to the motor 4 through the pulley 72 and the connecting belt 73, the rotation of the motor 4 will drive the rotating rod 71 to rotate, thereby causing the brush roller 74 at one end of the rotating rod 71 to rotate. While the brush roller 74 rotates, it will rotate and rub against the surface of the toothed ring 3 and gear 5 on one side of the support plate 1, thereby cleaning the surface of the toothed ring 3 and gear 5. This prevents foreign objects from adhering to the meshing surface, affecting normal meshing and rotation, and also ensures the normal use of the slewing platform support.

[0031] Reference Figure 1 and Figure 2 as well as Figure 4 As shown in the figure, this embodiment discloses that one end of the rotating rod 71 is rotatably connected to an auxiliary plate 76, and the auxiliary plate 76 is fixedly connected to the surface of the support plate 1. By setting the auxiliary plate 76, the rotating rod 71 can better maintain stability under the drive of the motor 4 and is less prone to shaking, thereby better cleaning the toothed ring 3 and gear 5. A scraper 75 is fixedly connected to the surface of the support plate 1, and the scraper 75 is slidably connected to the surface of the brush roller 74. By setting the scraper 75, when the brush roller 74 cleans the surface of the toothed ring 3 and gear 5, the scraper 75 can remove the dirt and impurities attached to the brush roller 74, ensuring the cleaning effect of the brush roller 74.

[0032] Working Principle: When the excavator is in operation, the slewing platform of the machine body rotates with the help of the slewing bracket on the chassis. At this time, the motor 4 on one side of the bracket plate 1 is started. The operation of the motor 4 drives the gear 5 to rotate, so that the gear ring 3 rotates under the limit of the assembly ring 2 on the surface of the bracket plate 1. At this time, the support plate 61 will rotate with the slewing platform plate, causing the roller 63 on one side of the support plate 61 to roll. The roller 63 connected to the rotating shaft 62 rolls on the inner wall of the slide rail 65 on the surface of the bracket plate 1. At the same time, the reinforcing plate 610 fixedly connected to one side of the support plate 61 will slide on the inner wall of the slide groove 611 on one side of the slide rail 65. When the slewing platform on one side of the machine body rotates under the drive of the bracket structure, it can better ensure stability and prevent damage to the bracket structure due to excessive weight of the machine body, which would affect the normal use of the slewing platform bracket. It also ensures that the machine body is not prone to shaking or even breaking from the bottom, thus ensuring the use effect and safety of the slewing platform bracket.

[0033] When the slewing bracket on the chassis supports the excavator platform, the motor 4 will rotate. Because the rotating rod 71 is connected to the motor 4 through the pulley 72 and the connecting belt 73, the rotation of the motor 4 will drive the rotating rod 71 to rotate, thereby causing the brush roller 74 at one end of the rotating rod 71 to rotate. As the brush roller 74 rotates, it will rotate and rub against the surface of the toothed ring 3 and gear 5 on one side of the bracket plate 1, thereby cleaning the surface of the toothed ring 3 and gear 5. This prevents foreign objects from adhering to the meshing surface, which would affect the normal meshing rotation, and also ensures the normal use of the slewing platform support.
