Description

Technical Field

[0001] The utility model belongs to the technical field of bucket elevator sprockets, and in particular relates to a split bucket elevator sprocket. Background Art

[0002] The so-called bucket elevator sprocket mainly refers to the sprocket with the lifting chain hanging inside the bucket elevator we are using on site. The manufacturing process of this sprocket can be simply summarized as: integral casting - fine machining - heat treatment. It is a continuous conveying machine that uses a series of buckets evenly fixed on the endless traction member to vertically lift materials. Bucket elevators have significant advantages such as large conveying capacity, high lifting height, stable and reliable operation, and long service life.

[0003] However, the teeth of the sprocket are easy to wear during use. After the bucket elevator has been running for a long time, the sprocket needs to be replaced. The sprocket is generally an integral part, so the entire sprocket needs to be removed for replacement. The disassembly and assembly process of the sprocket requires a lot of manpower and time, and the price of a complete set of sprockets is also high, resulting in high costs. At present, according to the comparative document disclosure (announcement) number: CN217558939U, although the sprocket can be replaced, there are still some shortcomings. For example, the sprocket is simply fixed with a locking component, which causes the sprocket to be unevenly stressed when it rotates at high intensity, thereby causing the sprocket to be damaged. The sprocket is fixed to the main shaft by multiple locking components, but the fixing efficiency is slow, thereby delaying the construction efficiency.

[0004] Therefore, a split bucket elevator sprocket is needed to solve the problems in the prior art that the fixing effect of the locking components is unstable and the efficiency of operating and installing multiple locking components is slow. Utility Model Content

When the positioning shaft is reset, it can drive the positioning shaft to be threadedly connected with the inner wall of the positioning port, thereby achieving the connection effect between the inner main shaft and the outer ring.

[0008] It should be noted in the scheme that the mounting mechanism includes two mounting grooves, the mounting grooves are opened on the inner wall of the mounting block, a compression spring is fixed to the bottom end of the inner wall of the mounting groove, a limiting block is fixed to the top end of the compression spring, and a positioning shaft is fixed to the top end of the limiting block.

[0010] A plurality of movable wheels are arranged on the outer wall of the positioning opening, so that the limiting movement can be performed on the inner wall of the limiting movable groove, thereby driving the positioning opening to perform the limiting movement, thereby making it possible to fix the positioning shaft more stably, thereby further stably connecting the outer ring and the main shaft.

[0011] It should be further explained that the mounting block moves on the inner wall of the rotating groove through the opening.

[0012] As a preferred implementation manner, the limit block is movably mounted on the inner wall of the installation groove, and the positioning shaft is movably mounted on the inner wall of the installation groove.

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] See also Figure 1-4 The utility model provides a split bucket elevator sprocket, comprising an outer ring 1 and a main shaft 10. The outer wall of the outer ring 1 is fixedly mounted with teeth 2 distributed in a circumferential manner. An opening 3 is provided on the surface of the outer ring 1. A rotating groove 4 arranged in a circular shape is provided in the middle of the outer ring 1. Mounting members 5 are fixedly mounted on both ends of the surface of the outer ring 1.

A mounting mechanism 12 is provided on the inner wall of the mounting block 11.

[0023] By having the mounting mechanism 12 move on the inner wall of the rotating groove 4 and then being stressed by the extrusion spring 122, it is possible to drive the limit block 123 to be stressed, thereby driving the positioning shaft 124 to be stressed, and further driving the positioning shaft 124 to move to the inner wall of the positioning port 8, and at the same time rotating the positioning port 8, so that the threaded groove 9 and the positioning shaft 124 can be threadedly connected, and further the positioning shaft 124 can be limited and fixed.

[0024] Further as Figure 4 As shown, it is worth explaining in detail that the mounting mechanism 12 includes two mounting grooves 121, the mounting grooves 121 are opened on the inner wall of the mounting block 11, a compression spring 122 is fixed to the bottom end of the inner wall of the mounting groove 121, a limiting block 123 is fixed to the top end of the compression spring 122, and a positioning shaft 124 is fixed to the top end of the limiting block 123.

[0025] By applying force to the extrusion spring 122, it can drive the limit block 123 to be subjected to force, and further drive the positioning shaft 124 to be reset. When the positioning shaft 124 is reset, it can drive the positioning shaft 124 to be threadedly connected with the inner wall of the positioning port 8, thereby achieving the connection effect between the inner main shaft 10 and the outer ring 1.

[0026] Further as Figure 3 and Figure 4 As shown, it is worth explaining in detail that a thread groove 9 is provided on the inner wall of the positioning opening 8 , and the outer wall of the positioning shaft 124 is threadedly provided, and the positioning shaft 124 is threadedly connected to the thread groove 9 .

[0027] This scheme has the following working process: when the outer ring 1 and the tooth 2 need to be replaced, first take out the inner main shaft 10, and then align the replaced outer ring 1 and the tooth 2 through the opening with the device and the mounting block 11, and then rotate the outer ring 1 so that the mounting block 11 can be aligned with the limiting movable groove 6, and then through the action of the extrusion spring 122, it can drive the limiting block 123 to be subjected to force, and then drive the positioning shaft 124 to be subjected to force, thereby driving the positioning shaft 124 to move to the inner wall of the thread groove 9, so that the positioning shaft 124 can be threadedly connected with the thread groove 9, and then by rotating the positioning port 8, it can further drive the positioning shaft 124 to be threadedly connected with the positioning port 8, thereby improving the stability of the positioning shaft 124.

[0028] According to the above working process, it can be known that: a plurality of movable wheels 7 are arranged on the outer wall of the positioning opening 8, so that the limiting movement can be performed on the inner wall of the limiting movable groove 6, thereby driving the positioning opening 8 to perform the limiting movement, so that the positioning shaft 124 can be fixed more stably, thereby further stably connecting the outer ring 1 and the main shaft 10.

[0032] By setting the outer wall of the positioning shaft 124 with a thread and then rotating the positioning port 8, a stable threaded connection can be achieved between the thread groove 9 and the positioning shaft 124. At the same time, the positioning shaft 124 can be limited, and the positioning port 8 can be fixed, so that the outer ring 1 and the main shaft 10 can be fixed through the positioning port 8 and the positioning shaft 124.

[0033] In summary: by the installation mechanism 12 moving on the inner wall of the rotating groove 4, and then exerting force through the extrusion spring 122, it is possible to drive the limit block 123 to be exerted, thereby driving the positioning shaft 124 to be exerted, and then driving the positioning shaft 124 to move to the inner wall of the positioning port 8, and then rotating the positioning port 8, so that the threaded groove 9 and the positioning shaft 124 can be threadedly connected, and further the positioning shaft 124 can be limited and fixed.
