Description

Technical Field

[0001] This utility model relates to the technical field of cylindrical mixer equipment, specifically to a special anti-reverse braking tool for the maintenance of cylindrical mixers. Background Technology

[0002] Cylindrical mixers are crucial equipment in sintering and pelletizing systems, primarily used for mixing and granulating sintered ore raw materials to meet the mixing requirements during sintering. The mixer cylinder is large and heavy, and its inner wall often has varying degrees of material adhering to it. When the cylinder stops, its inertia causes it to rotate unpredictably, making manual rotation necessary to locate it at a suitable maintenance position. Without a dedicated fixing device, the cylinder's position may shift due to inertia, requiring repeated manual rotation to determine the maintenance location – a time-consuming and labor-intensive process. Furthermore, any rotation of the cylinder during maintenance can cause significant personal injury to maintenance personnel, ultimately impacting the overall safety and efficiency of cylindrical mixer maintenance. Utility Model Content

[0003] This utility model provides a special anti-reverse braking tool for the maintenance of a cylindrical mixer, in order to solve the problems mentioned above.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A special anti-reverse braking tool for the maintenance of a cylindrical mixer includes a rotating rod, one end of which is threaded with a knob, and the other end of which is threaded with multiple wedges arranged flush with each other. A clamping rod is also connected to the side of the rotating rod located between the wedges.

[0006] Furthermore, one end of the rotating rod is connected to a handle, the knob and the handle are threaded together, and a locking pin is provided near the handle on the rotating rod.

[0007] Furthermore, a connecting plate is threaded to the other end of the rotating rod, and a locking nut is also fitted between the connecting plate and the rotating rod.

[0008] This utility model has the following beneficial effects:

[0009] This utility model provides a special anti-reverse braking tool for the maintenance of a cylindrical mixer. It mainly consists of a rotating rod, a wedge, a tightening rod, a locking nut, and a knob. By rotating the knob, the tightening rod is retracted to the inside of the wedge. The wedge is then inserted between the stopped mixer drum and the mixer support roller, forming an anti-reverse tool clamp on both sides of the drum. The knob is rotated to adjust the placement position, and finally, the locking nut is rotated to lock the wedge position. This achieves a stopping limit on the mixer drum, effectively preventing rotation during maintenance, improving the overall safety and efficiency of maintenance. It solves the problem that currently, the lack of a dedicated cylindrical mixer rotation locking device often leads to the mixer easily reversing, ultimately reducing the safety and efficiency of maintenance operations.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1-4 As shown, a special anti-reverse braking tool for the maintenance of a cylindrical mixer includes a rotating rod 1. One end of the rotating rod 1 is threadedly connected to a knob 8, and the other end of the rotating rod 1 is threadedly connected to a plurality of flatly arranged wedges 4. A clamping rod 6 is also connected to the side of the rotating rod 1 located between the wedges 4.

[0018] One end of the rotating rod 1 is connected to the handle 2. The knob 8 and the handle 2 are threaded together, and a backstop pin 7 is provided near the rotating rod 1 of the handle 2.

[0019] The other end of the rotating rod 1 is threadedly connected to a connecting plate 3, and a locking nut 5 is also fitted between the connecting plate 3 and the rotating rod 1.

[0020] The tool is made entirely of Q235 carbon steel. The wedge block 4 measures 150*140*40mm with a wedge angle of 18.92° and has a Tr24*3T internal thread at its center. The handle 2 measures Φ24*500mm, with a front section of Φ16*60mm and a rounded head (R5). A 150mm section in the middle has a Tr24*3T external thread, and the rear section is a Φ24*274mm round steel. A Φ16*150mm round steel is welded to the end, forming the clamping rod 6. The end of the handle 2 has an M10*30mm... The internal thread has an M6 continuous fixing hole drilled in the threaded hole; the locking nut 5 is made of Φ54*30mm round steel with a Tr24*3T-shaped internal thread at the center and the outer surface is machined into a mesh surface m0.3GB6403.3-1986; the knob 8 is made of Φ54*30mm round steel in four sections: the front section is Φ9.5*5mm round steel, the second section is Φ5*10mm round steel, the third section is Φ9.5*10mm round steel, and the end section is Φ20*15mm round steel with a Φ6 continuous fixing hole drilled in the center.

[0021] In practical application, when the mixer is shut down for maintenance, the maintenance personnel manually rotate the mixer drum 9 to the maintenance position, and then install the anti-reverse braking tool between the mixer drum 9 and the mixer support roller 10. During installation, the handle 2 can be pulled out of the thread of the wedge block 4 as much as possible, and then the locking nut 5 is tightened by hand and pushed between the mixer support roller 10 and the mixer drum 9. Then, the knob 8 is turned to wedge the wedge block 4 into the contact surface of the mixer drum 9 and the mixer support roller 10, and then the anti-reverse pin 7 is locked. Two of these tools are used for each mixer drum 9 and placed diagonally to fix the mixer drum 9 firmly and prevent it from rotating. Furthermore, to prevent the tool from falling off, a chain or thin steel wire rope can be used to hang it on the knob 8 for fixation. After maintenance, loosen the locking nut 5, rotate the handle 2, and press the arc-shaped clamping rod 6 at the end of the tool against the contact surface. Then, remove the wedge 4 from the contact surface between the mixer cylinder 9 and the mixer support roller 10. The tool can then be easily and safely removed. The entire process achieves the stopping limit of the mixer cylinder 9, thereby effectively preventing the mixer cylinder 9 from rotating during maintenance and improving the overall safety and efficiency of maintenance. Therefore, the tool has good practicality.
