Description

Technical Field

[0001] The utility model belongs to the technical field of shot blasting machines, and particularly relates to a novel driving device for shot material lifting. Background Technique

[0002] As a key device in the heat treatment line, the main task of the shot blasting machine is to remove the surface scale of the steel plate, which determines the surface quality of the product before entering the furnace. It is particularly important for medium and heavy plates with high added value.

[0003] The shot material lifting driving device is mainly responsible for driving the shot material circulation system in the shot blasting machine to meet the required shot material supply for shot blasting production. The structure of the existing driving device is as Figure 5 shown. The shaft body on the roller is divided into a driving side and a non-driving side, and the driving side is connected to the reduction motor.

[0004] The disadvantages of this driving device in use are as follows:

[0005] 1) Due to the relatively harsh use environment of the driving device, the shaft head on the driving side is prone to wear, shortening the service life of the driving device.

[0006] 2) Due to the relatively harsh use environment of the driving device, and it is not easy to inspect the bearing installation position of the driving device, the service life of the bearing is relatively short, and the bearing needs to be replaced within a cycle of 8 - 10 months. However, due to the long length of the roller, the space between the reduction motor, the bearing and it is small (inconvenient for overhead crane lifting), resulting in great inconvenience in replacing and disassembling the reduction motor and the bearing, and the replacement operation and maintenance time are long.

[0007] 3) The cross-section of the roller is designed as a plane, and its use environment is relatively harsh. When driving the lifting belt, the edge of the belt wears quickly, seriously affecting the use effect of the driving device and severely restricting the production of the heat treatment production line. Content of the Utility Model

[0008] The purpose of the utility model is to provide a novel driving device for shot material lifting. By designing the non-driving side shaft head and the driving side shaft head of the core shaft on the roller to have the same structure and a relatively large length, the installation distance of the bearing of the driving device is ensured. The symmetrical design of the shaft head meets the installation requirements of the device. After the shaft head on the driving side wears, the non-driving side shaft head can be used, improving the interchangeability of the driving device and effectively extending the service life.

[0009] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0010] The utility model is a novel driving device for shot material lifting, including a roller, a reduction motor and a combined core shaft;

[0011] The roller includes a core cylinder and an outer cylinder body. A side plate body is provided between the core cylinder and the outer cylinder body, and a plurality of positioning grooves are provided on the inner wall of the core cylinder;

[0012] The combined mandrel includes a left shaft body and a right shaft body. Key grooves are provided on the circumferential surface of the left shaft body. One end of the left shaft body is connected with an insertion section through a transition section, and a plurality of positioning edges are provided on the circumferential surface of the insertion section;

[0013] The structural features of the left shaft body are the same as those of the right shaft body. The insertion sections of the left shaft body and the right shaft body are both arranged in the core cylinder with a gap. The end faces of the insertion sections on the left shaft body and the right shaft body are mutually attached, and the connection surface is located in the middle of the core cylinder. The positioning edges are arranged in the positioning grooves with a gap;

[0014] One end of the insertion section close to the key groove extends beyond the side plate body on the outer side of the roller and forms an outward convex part, and the outward convex part is fixed to the side plate body.

[0015] Further, the number of the side plate bodies is two or three, and a plurality of through openings are provided on the side plate bodies.

[0016] Further, the end faces at both ends of the core cylinder are flush with the outer surfaces of the side plate bodies on both sides of the roller, and both ends of the positioning grooves extend to the end faces at both ends of the core cylinder.

[0017] Further, the insertion section is fixed to the side plate body on the outer side of the roller by welding, and the welding point is located at the connection part between the outward convex part and the side plate body.

[0018] Further, the insertion section is fixed to the side plate body on the outer side of the roller by a flange. The flange is arranged on the outward convex part and fits with the outer side of the side plate body.

[0019] Further, the outer surface of the outer cylinder body is a curved surface structure.

[0020] The utility model has the following beneficial effects:

[0021] 1. In the utility model, the non-driving side shaft head and the driving side shaft head of the mandrel on the roller are designed to have the same structure and a relatively large length, ensuring the installation distance of the bearings of the driving device. The symmetrical design of the shaft head meets the installation requirements of the device. After the driving side shaft head is worn, the non-driving side shaft head can be used, improving the interchangeability of the driving device and effectively extending the service life.

[0022] 2. The roller designed in the utility model is installed in the middle of the driving side shaft head and the non-driving side shaft head. At the same time, the reduction motor is installed on the other side of the driving device. Without changing the bearing installation distance, the maintenance space for disassembling and assembling the reduction motor and the bearings of the driving device is increased, which is beneficial to the maintenance of the driving device and its bearings.

[0023] 3. The utility model designs a combined mandrel, which facilitates the positioning, installation and disassembly of the mandrel. Meanwhile, it is beneficial to maintenance and assembly after the mandrel is damaged. At the same time, the cooperation between the positioning edge and the positioning groove ensures the stability and strength between the mandrel and the roller.

[0024] 4. The utility model improves the roller body cross-section of the shaft cylinder from the original plane to a curved surface, which improves the edge wear problem during the use of the belt, and enhances the durability and service life of the new driving device and the belt.

[0025] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. Description of the Drawings
