Description

Technical Field

[0001] This invention belongs to the field of mineral processing application technology, and specifically relates to a protection device for the crossbeam and center hole of the upper frame of a cone crusher. Background Technology

[0002] The upper frame, as a major component of the cone crusher, is worth millions of yuan. The upper frame bushing is installed in the central hole of the upper frame and serves as a support point for the rotation of the crusher's main shaft during operation, thus bearing significant forces. During production, the upper frame beams, the upper outer surface of the central hole, and other parts are directly subjected to the impact and friction of the raw ore, resulting in rapid wear. After the upper frame beams and the upper outer surface of the central hole wear down, their strength decreases, which can easily lead to cracks in the central hole, causing the entire upper frame to be scrapped.

[0003] Therefore, in order to extend the service life of the upper frame and reduce the operating cost of the crusher, it is necessary to protect it. Summary of the Invention

[0004] To address the above problems, this invention provides a protective device for the crossbeam and center hole of the upper frame of a cone crusher, employing the following technical solution:

[0009] Furthermore, the second protective structure includes a protective cover covering the outer surface of the upper part of the central hole of the upper frame, the protective cover having a plurality of circumferentially distributed strip-shaped holes.

[0010] Furthermore, the protective cover includes a first connecting ring, a plurality of second protective columns, and a second connecting ring;

[0011] The bottom of the first connecting ring is connected to the upper outer surface of the center hole of the upper frame, and the top of the first connecting ring is connected to the second connecting ring through a plurality of second protective columns. The interval between two adjacent second protective columns is d. The first connecting ring, the two adjacent second protective columns and the second connecting ring form the strip hole.

[0012] Furthermore, the included angles between the plurality of second protective columns and the first connecting ring are all 80° to 90°.

[0013] Furthermore, the third protective structure includes a protective ring, which is sleeved on the outside of the bottom of the central hole of the upper frame, and the inner diameter of the protective ring is matched with the bottom diameter of the central hole of the upper frame.

[0014] Furthermore, the first protective column is made of Q235 steel, and the bottom of each first protective column is welded to the body of the cone crusher, while the top of the first protective column is welded to the upper frame crossbeam.

[0015] Furthermore, the first connecting ring, the plurality of second protective columns, and the second connecting ring are made of Q235 steel; the bottom of each second protective column is welded to the upper outer surface of the center hole of the upper frame, and the top of the second protective column is welded to the second connecting ring.

[0016] Furthermore, the protective ring is made of Q235 steel, and the protective ring is welded to the bottom lower surface of the center hole of the upper frame.

[0017] The beneficial effects of this invention are:

[0018] 1. This invention, by setting protective structures on both sides of the upper frame crossbeam and around the outer surface of the upper frame center hole of the cone crusher, greatly reduces the impact and wear of ore on the upper frame crossbeam and the upper outer surface of the upper frame center hole of the cone crusher during production, thereby extending the service life of the upper frame of the cone crusher and reducing the operating cost of the crusher.

[0019] 2. The cone crusher upper frame crossbeam and center hole protection device of the present invention have a simple structure. Each component can be manufactured first, and then the cone crusher can be modified on site. Each component is made of easy-to-weld materials, which facilitates on-site construction, reduces costs, and makes operation convenient.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] It should be noted that the terms "first," "second," etc., used in this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein. In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," "horizontal," "lateral," "longitudinal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

[0026] This invention provides a protective device for the crossbeam and center hole of the upper frame of a cone crusher, which reduces wear on the upper outer surface of the crossbeam and center hole of the upper frame, extends the service life of the upper frame, and reduces the operating cost of the crusher.

[0027] like Figure 1 As shown, a protective device for the upper frame beam 1 and the center hole of a cone crusher includes a first protective structure 2 disposed on both sides of the upper frame beam 1, a second protective structure 4 disposed on the upper outer surface of the center hole 3 of the upper frame, and a third protective structure 5 disposed circumferentially along the bottom of the center hole 3 of the upper frame.

[0028] This invention, by setting protective structures around the upper frame beam 1 and the upper frame center hole 3 of the cone crusher, greatly reduces the impact and wear of ore on the upper outer surface of the upper frame beam 1 and the upper frame center hole 3 during the production process, thereby extending the service life of the upper frame of the cone crusher and reducing the operating cost of the crusher.

[0029] For example, the first protective structure 2 includes a plurality of first protective columns 6, and the interval between two adjacent first protective columns 6 is d, for example, the interval d is 10-30mm; the bottom of each first protective column 6 is connected to the body of the cone crusher, and the top of each first protective column 6 is connected to the upper frame beam 1.

[0030] For example, the included angles between the multiple first protective columns 6 and the upper frame crossbeam 1 are all 80° to 90°.

[0031] For example, the first protective column 6 can be made of round steel with a diameter d1 of Φ30mm and a length d2 of approximately 400mm; or the first protective column 6 can be made of square steel with a width d1 of approximately 60mm and a length d2 of approximately 300mm.

[0032] For example, the first protective column 6 is made of Q235 steel. The bottom of each first protective column 6 is welded to the body of the cone crusher, and the top of the first protective column 6 is welded to the upper frame beam 1.

[0033] Q235 steel possesses excellent mechanical properties, exhibiting high strength and toughness. It belongs to the medium-low carbon steel category, with a tensile strength of 370-500 MPa, a yield strength of 235 MPa, and an elongation of ≥26%. These mechanical properties enable Q235 steel to maintain stable performance under various stress conditions.

[0034] Q235 steel is low in cost and easy to weld, with good weldability, allowing for connection and repair via methods such as arc welding, gas welding, and resistance welding. The use of Q235 steel for the first protective column 6 reduces the manufacturing cost of the protective device.

[0035] For example, the second protective structure 4 includes a protective cover covering the outer surface of the upper part of the central hole 3 of the upper frame, the protective cover having a plurality of circumferentially distributed strip holes.

[0036] For example, the protective cover includes a first connecting ring 7, a plurality of second protective columns 8 and a second connecting ring 9. The bottom of the first connecting ring 7 is connected to the upper outer surface of the center hole 3 of the upper frame, and the top of the first connecting ring 7 is connected to the second connecting ring 9 through a plurality of second protective columns 8.

[0037] The interval between two adjacent second protective pillars 8 is d. The first connecting ring 7, the two adjacent second protective pillars 8, and the second connecting ring 9 form a strip-shaped hole. The included angle between the multiple second protective pillars 8 and the first connecting ring 7 is 80° to 90°.

[0038] For example, the second protective column 8 can be made of round steel with a diameter of d1 and a length of d2; or the second protective column 8 can be made of square steel with a width of d1 and a length of d2.

[0039] For example, the first connecting ring 7, the multiple second protective columns 8, and the second connecting ring 9 are made of Q235 steel. The bottom of each second protective column 8 is welded to the upper outer surface of the center hole 3 of the upper frame, and the top of the second protective column 8 is welded to the second connecting ring 9.

[0040] For example, the third protective structure 5 includes a protective ring, which is fitted around the bottom outer side of the center hole 3 of the upper frame. The inner diameter of the protective ring is matched with the bottom diameter of the center hole 3 of the upper frame. For example, the inner diameter of the protective ring is d3, the outer diameter is d4, and the thickness is d5. The lower surface of the bottom of the center hole 3 of the upper frame is protected by the protective ring. The size of the protective ring is determined according to the size of the center hole of the cone crusher.

[0041] For example, the protective ring is made of Q235 steel and is welded to the bottom surface of the center hole 3 of the upper frame.

[0042] The cone crusher upper frame crossbeam 1 and the center hole protection device of the present invention have a simple structure. Each component can be manufactured first, and then the cone crusher can be modified on site. Each component is made of easy-to-weld materials, which facilitates on-site construction, has low cost, and is easy to operate.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
