Description

Technical Field

[0001] The utility model belongs to the technical field of roller disc brakes, and in particular relates to a roller disc brake device. Background Art

[0002] A cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires. When working, the cable is wound on a roller, which is also called a tube reel. It is a cable winder, a cable reel, a reel, and a drum. As the name suggests, the tube or wire is wound on an axis. It is simple and practical, and is widely used in various production and assembly workshops and maintenance workshops. However, the existing roller cannot brake in time. After braking, the cable on the roller will fall off, increasing the working time of the staff to reel up. Therefore, a roller brake device is proposed.

[0003] For example, a Chinese patent with publication number CN218579272U discloses a cable drum brake device, comprising: a bearing base; a first mounting seat, the first mounting seat is arranged on the bearing base; a brake shoe push rod, the brake shoe push rod is provided with a brake shoe, the brake shoe is provided with an upward braking surface, the brake shoe push rod is hinged to the first mounting seat through a first hinge axis, and the brake shoe push rod can rotate vertically around the first hinge axis; a push rod, one end of the push rod is a hinged end, and the other end is a force-applying end, and the hinged end is hinged to the brake shoe push rod through a second hinge axis; a second mounting seat, the second mounting seat is arranged on the bearing base; a suspension rod, one end of the suspension rod is hinged to the second mounting seat through a third hinge axis, the suspension rod can rotate vertically around the third hinge axis, and the other end of the suspension rod is suspended in the middle of the push rod and is hinged to the push rod through a fourth hinge axis.

[0004] The above patent has the following problems:

[0005] Compared with the cable reel emergency brake device in the prior art, which cannot brake in time, after the emergency brake is completed, the cable reel may move forward due to inertia, causing the cable to fall, and the staff needs to roll it up, affecting the work process and delaying the work time. In addition, the brake pads in the prior art cannot be adjusted, and directly block the cable reel after braking, affecting the dragging of the cable reel, resulting in reduced work efficiency. The dragging force may also cause the cable reel to slip. In view of this, we propose a roller brake device. Utility Model Content
