Description

Technical Field

[0001] The utility model belongs to the technical field of excavator rotary platforms, in particular to a novel excavator rotary platform. Background Art

[0002] The new excavator slewing platform is an optimized and improved structural design for excavator equipment, aiming to improve the performance, stability and operating efficiency of the excavator.

[0003] The existing excavator slewing platform usually has rollers embedded in the supports. Due to the large size of the slewing platform, the support as a whole is large and heavy. When maintenance work is required, it is not easy to remove the rollers in the support, and the staff needs to spend a lot of time to remove them. In addition, there will be violent methods such as knocking during the disassembly process, which makes it easier to damage the support or rollers. Replacing the entire support will greatly increase the maintenance cost. Therefore, we proposed a new excavator slewing platform. Utility Model Content

[0026] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-5 As shown, the utility model is a new type of excavator slewing platform, including a slewing platform body 1, a support 11 is provided above the slewing platform body 1, an inner gear ring 111 is fixedly connected to the inner wall of the support 11, and a separation component 12 is provided inside the slewing platform body 1;

[0028] The separation component 12 includes a fixed support ring 121 fixedly connected to the inner wall of the rotary platform body 1, and a plurality of placement circular grooves 122 are opened on the top of the fixed support ring 121, and rollers 123 are inserted into the plurality of placement circular grooves 122. By setting the separation component 12, there is a gap between the bottom of the support 11 and the fixed support ring 121 after installation, which facilitates subsequent disassembly. When the roller 123 needs to be replaced, the limit of the support 11 is released, and then the support 11 is pulled upward to expose the roller 123. The damaged roller 123 can be directly taken out and replaced. The operation is simple and convenient, and violent disassembly is avoided. It not only greatly reduces the maintenance cost, but also avoids damage to the support 11 and other rollers 123.

[0029] The outer side of the support 11 is plugged into the inner side of the rotary platform body 1, and there is a gap between the bottom of the support 11 and the top of the fixed support ring 121. The outer surface of the roller 123 contacts the bottom of the support 11. Since there is a gap between the bottom of the support 11 and the top of the fixed support ring 121, the support 11 and the fixed support ring 121 are in a separated state, thereby reducing friction.

[0030] A limit assembly 13 is provided at each of the four corners of the top of the slewing platform body 1. The limit assembly 13 includes a fixing seat 131 fixedly connected to the top of the slewing platform body 1, and a plug plate 132 is slidably connected to the inner side of the fixing seat 131. A threaded block 133 is fixedly connected to the inner wall of the fixing seat 131, and a nut 134 is threadedly connected to the outer surface of the threaded block 133. By setting the limit assembly 13, specifically after the support 11 is placed, the plug plate 132 on the fixing seat 131 is pushed so that the plug plate 132 is inserted into the convex ring on the outer side of the support 11, and then the nut 134 is rotated clockwise with a tool to fix the plug plate 132. At this time, the plug plate 132 will limit the support 11 to prevent the support 11 from falling off, which is convenient for the excavator to perform lifting work. At the same time, there is a small gap between the bottom of the plug plate 132 and the support 11, which will not affect the rotation of the support 11.

[0031] The fixing seat 131 is U-shaped, and a straight slot is provided inside the insert plate 132. The inner side of the straight slot is adapted to the threaded block 133. A convex ring is fixedly connected to the outer side of the support 11. The insert plate 132 is arranged above the convex ring. There is a gap between the bottom of the insert plate 132 and the top of the convex ring. The U-shaped setting of the fixing seat 131 can limit the insert plate 132, so that the insert plate 132 can move in a straight line.

[0032] A support base 14 is fixedly connected to the inner wall of the rotating platform body 1, a motor 141 is fixedly connected to the inner top of the support base 14, a gear 142 is fixedly connected to the top output end of the motor 141, and the gear 142 is meshed with the inner gear ring 111. After the support 11 is plugged into the rotating platform body 1, the inner gear ring 111 will be meshed with the gear 142, thereby not affecting the installation and disassembly of the support 11.

[0033] An annular stabilizing rail 15 is fixedly connected to the top of the rotary platform body 1. The top of the annular stabilizing rail 15 is rotatably connected to the inner side of the bottom of the support 11. When the support 11 rotates, it will rotate on the annular stabilizing rail 15 to improve the stability of the support 11 during rotation.

[0034] There is a gap between the bottom of the convex ring on the outside of the support 11 and the top of the rotating platform body 1. The bottom of the support 11 is an annular recess, which is adapted to the roller 123. The annular recess at the bottom of the support 11 can better adapt to the roller 123 and reduce the shaking of the roller 123.

[0035] A specific application of this embodiment is:

[0036] When in use, first place several rollers 123 into the placement groove 122 from the top of the fixed support ring 121. The top of the placement groove 122 is a flat opening, so the rollers 123 can be placed quickly. When the rollers 123 are placed, insert the support 11 from the top of the rotary platform body 1. The bottom of the support 11 contacts the surface of the roller 123. At the same time, the inner gear ring 111 is meshed with the gear 142, and the inner side of the bottom of the support 11 is plugged into the annular stabilizing rail 15. This method can quickly install the support 11 with higher efficiency. When the support 11 is placed, push the plug plate 132 on the fixed seat 131 so that the plug plate 132 is inserted into the convex ring on the outside of the support 11, and then use a tool to turn the nut 134 clockwise. When the nut 134 contacts the plug plate 132, fix the plug plate 132. At this time, the plug plate 132 will limit the support 11 to prevent the support 11 from falling off. At the same time, there is a small gap between the bottom of the plug plate 132 and the support 11. The spacing will not affect the rotation of the support 11. The support 11 is connected and fixed to the excavator by several bolts. By starting the motor 141 to drive the gear 142 to rotate, the gear 142 drives the support 11 to rotate through the inner gear ring 111, and the support 11 drives the excavator to rotate. During the rotation of the support 11, the bottom will slide on the roller 123, which can make the rotation smoother. At the same time, the support 11 rotates on the annular stabilizing rail 15 to improve the stability of the support 11 during rotation. When the roller 123 inside the fixed support ring 121 is damaged, the excavator is disassembled, and the nut 134 is loosened, and the plug plate 132 is pulled away from the support 11 to release the limit of the support 11. Then, the support 11 is pulled upward to expose the roller 123. The damaged roller 123 can be directly taken out and replaced. The operation is simple and convenient, avoids violent disassembly, not only greatly reduces the maintenance cost, but also avoids damage to the support 11 and other rollers 123.
