Description

Technical Field

[0001] The utility model relates to the technical field of dry slag machines, in particular to a tool for disassembling a sleeve die forging chain core shaft. Background Art

[0002] A dry slag conveyor is a slag handling device used in power plant boilers, cooling and conveying boiler slag. This latest generation dry slag conveyor utilizes a hopper as a carrier for slag and heat exchange, a sleeve die-forged chain as a transmission center, and features synchronous self-cleaning and conveying. It utilizes penetrating heat exchange and quantitative air control technology. The sleeve die-forged chain consists of chain plates, sleeves, a mandrel, connecting plates, and screws.

[0003] During daily production, the sleeve die-forged chain wears out due to the long-term operation of the dry slag machine, stretching the sleeve die-forged chain length. This wear and tear necessitates the removal of the sleeve die-forged chain mandrel to cut the chain. This is due to the small clearance between the mandrel and the sleeve, and the fact that the sleeve die-forged chain expands due to the high temperature of the slag during daily use, making removal of the mandrel difficult. Traditional disassembly methods, such as hammering, damage the sleeve die-forged chain, and require lengthy and labor-intensive maintenance. Utility Model Content

[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions of the embodiments of the present application will be clearly and completely described below in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the described embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] Unless otherwise defined, technical or scientific terms used herein shall have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs.

[0022] The specific embodiments of the present invention are described in detail and completely below with reference to the accompanying drawings.

[0023] like Figure 1As shown, a tool for removing a mandrel from a sleeve die forging chain comprises a chuck 3, which comprises a base plate and two clamping plates. One end of each clamping plate is fixedly connected to the two ends of one side of the base plate, and the other ends respectively engage with the slots on both sides of one end of the mandrel of the sleeve die forging chain. The tool also comprises an operating rod 1, which is detachably connected to the base plate of the chuck 3. In a sleeve die forging chain, components such as chain plates, sleeves, mandrels, connecting plates, and screws are included. After the mandrel passes through the sleeve, its two ends are respectively inserted into the connecting holes of the chain plates. A connecting plate is inserted into the slots and fixedly connected to the chain plates by bolts. When disassembling the mandrel, first unscrew the bolts, remove the connecting plate, insert the two clamping plates of the barrel die forging chain mandrel disassembly tool into the slots on both sides of one end of the mandrel, twist the operating rod to a certain angle, and the mandrel, clamped by the clamping plates, rotates due to the torque applied by the operating rod, overcomes the friction between the mandrel and the sleeve and becomes loose, and then the mandrel can be easily removed. After removing the mandrel, the chain plate that has been stretched due to wear is replaced with a normal chain plate, completing the maintenance of the sleeve die forging chain. This reduces the damage to the sleeve die forging chain caused by traditional hammer strikes, and reduces the maintenance time and labor intensity of the maintenance operation. The operating rod 1 is detachably connected to the base plate of the clamping plate 3, and different clamping plates 3 can be replaced according to the different mandrels of the sleeve die forging chain.

[0024] Specifically, the detachable connection is a threaded connection, which can provide stable connection strength, ensure a tight fit between the connected parts, and is not affected by human factors, with stable and reliable performance.

[0025] Specifically, the detachable connection is a snap connection, which is easy to operate and does not require complicated installation steps and tools, thereby improving work efficiency.

[0026] Specifically, the splint is C-shaped, which can withstand greater force, ensuring high stability during the fixing process and is not easy to loosen or deform.

[0027] Specifically, the splint is L-shaped, which has high durability and stability and can maintain performance for a long time.

[0028] Specifically, if Figure 2 As shown, the operating rod 1 is a screw rod and also includes a two-legged bracket 2. The supporting surface of the two-legged bracket 2 has a screw hole that cooperates with the screw rod. The support of the operating rod 1 by the bracket 2 ensures the stability of the operating rod 1, further reducing the labor intensity of maintenance workers.

[0029] Specifically, after the screw rod passes through the screw hole, a handle is provided at the end of the screw rod. The provision of the handle further reduces the labor intensity of the maintenance workers and improves the comfort of the maintenance work.

[0030] To solve the above-mentioned technical problems, another technical solution of the present invention is a sleeve die forging chain mandrel removal tool, comprising a chuck 3, which comprises a base plate and two clamping plates, one end of each clamping plate being fixedly connected to the two ends of one side of the base plate, and the other end of each clamping plate being engaged with the slots on both sides of one end of the sleeve die forging chain mandrel, and an operating lever 1, which is integrally formed with the base plate of the chuck 3. The integral formation of the operating lever 1 and the base plate of the chuck 3 improves the convenience and reliability of maintenance operations.

[0031] Specifically, the splint is C-shaped, which can withstand greater forces, ensuring high stability during the fixing process and is not prone to loosening or deformation.

[0032] Specifically, the splint is L-shaped, which has high durability and stability and can maintain performance for a long time.

[0033] The above description is merely an exemplary embodiment of the present application and is not intended to limit the scope of protection of the present application. The scope of protection of the present application is determined by the appended claims.
