Description
Technical Field
[0001] The utility model belongs to the technical field of bucket wheel machines, in particular to a hinge seat of a bucket wheel machine. Background Art
[0002] Bucket wheel excavator is also called bucket wheel excavator. It is a multi-bucket excavator that uses multiple buckets installed on the rotating wheel at the front end of the boom for continuous excavation. It is used for excavation of large amounts of earth, stripping and mining in mines, and loading and unloading operations in large material yards. It has high productivity and large excavation force. It is used in large-scale construction, water conservancy projects and mines. It is often matched with transportation equipment to form a continuous operation line.
[0003] The existing bucket wheel excavator has a hinge seat at the bottom, which is installed together with the bucket wheel excavator frame through a slewing bearing, and a walking mechanism is installed under the hinge seat. The hinge seat structure on the market has too much dead weight, which increases the load of the whole machine, increases the requirements of the whole machine on the site bearing capacity, and increases the operating risk of the bucket wheel excavator. Utility Model Content
[0004] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide a hinge seat of a bucket wheel machine, which effectively solves the problem of excessive deadweight of the hinge seat.
[0005] The technical solution to solve the technical problem is: it includes a door frame, which is a circular ring shape, and multiple extension platforms are evenly fixed around the door frame. A support base is installed at the lower end of the extension platform. The support base includes an upper frame and a lower frame. A cross bracket is fixed in the upper frame, and the lower frame is provided with mounting holes arranged in the front and rear directions. The lower frame is installed with a limit baffle located on the outside of the mounting hole, and a left and right through groove is provided in the lower frame. The mounting hole and the slot are connected to each other, and an annular through groove is provided in the door frame.
[0006] Preferably, the cross section of the through groove is polygonal.
[0007] Preferably, the number of the extension platforms is four.
[0008] Preferably, the upper end of the upper frame is fixedly connected to the lower end of the extension platform, and the lower end of the upper frame is fixedly connected to the upper end of the lower frame.
[0009] Preferably, a cavity is provided in the extension platform.
[0010] Compared with traditional equipment, the utility model has the following advantages: 1) The extension platform structure has a more uniform force distribution, ensuring the overall stability; the through slot and cavity structure reduce the weight of the door frame and the extension platform, thereby reducing production costs, facilitating transportation, and being economical and practical while ensuring their safety; 2) The through slot, mounting hole and limit baffle are combined to ensure the space and safety of the walking mechanism installation, and the operation is simple and the stability is good.

[0018] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.
[0019] Depend on Figures 1 to 6 A hinge seat of a bucket wheel excavator is provided, including a gantry 1, which is annular, with multiple extension platforms 2 evenly fixed around the gantry 1, a support seat 3 installed at the lower end of the extension platform 2, the support seat 3 including an upper frame 4 and a lower frame 5, a cross bracket 6 is fixed in the upper frame 4, the lower frame 5 is provided with mounting holes 7 arranged in the front and rear directions, the lower frame 5 is provided with a limit baffle 8 located on the outside of the mounting hole 7, a left and right through slot 9 is provided in the lower frame 5, the mounting hole 7 and the slot 9 are connected to each other, and an annular through groove 10 is provided in the gantry 1.
[0020] The cross section of the through groove 10 is polygonal.
[0021] The number of the extension platforms 2 is four.
[0022] The upper end of the upper frame 4 is fixedly connected to the lower end of the extension platform 2 , and the lower end of the upper frame 4 is fixedly connected to the upper end of the lower frame 5 .
[0023] The extension platform 2 is provided with a cavity 11 therein.
[0024] When the utility model is in use, a slewing bearing is installed on the upper end of the gantry 1, and the slewing bearing controls the rotational movement of the bucket wheel excavator. A walking mechanism is installed in the mounting hole 7, and the slot 9 ensures the installation space of the walking mechanism. The limit baffle 8 is installed on the lower frame 5 by screws, and the limit baffle 8 limits the outer side of the mounting hole 7, effectively ensuring the stability and safety of the running of the walking mechanism, and then the walking mechanism can drive the support seat 3, the gantry 1 and the bucket wheel excavator to operate as a whole. In addition, the four extension platforms 2 evenly distributed on the circumference can ensure the overall stability of the gantry 1. The annular through groove 10 structure reduces the weight of the gantry 1 while ensuring the rigidity of the gantry 1, reduces the cost, and facilitates transportation. The cross-crossed brackets 6 ensure the stability of the upper frame 4.
[0025] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the protection scope of the technical solution of the utility model.
