It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] like Figure 1-Figure 4 As shown, the brake device for the dispatching winch comprises a workbench 1, on which a brake mechanism 2 is arranged;

[0025] The brake mechanism 2 includes two slides 201, two motors 205 and two slide grooves 203. Brake pads 202 are fixed on opposite sides of the two slides 201. Two symmetrical racks 204 are fixed on opposite sides of the two slides 201. A round rod 207 is installed at the output end of each motor 205. A gear 206 is fixedly sleeved on the outer surface of each round rod 207. The two bottom ends of each slide 201 are respectively slidably connected to the inside of the two slide grooves 203. The four racks 204 are divided into two groups. The teeth of each group of racks 204 are respectively meshed with the teeth of each gear 206. The two slide grooves 203 are both opened on the top of the workbench 1. The two motors 205 are installed on the top of the workbench 1. The top of the workbench 1 is installed with Two symmetrical brackets 5, the interiors of the two brackets 5 are rotatably connected with a rotating rod 6 through a bearing, the outer surface of the rotating rod 6 is fixedly sleeved with a reel 7, a motor 8 is installed on one side of one of the brackets 5, the output end of the motor 8 is installed with one end of the rotating rod 6, a limiting rod 3 is fixed on the surface of each group of racks 204, four mounting seats 4 are installed on the top of the workbench 1, the four mounting seats 4 are divided into two groups, each round rod 207 is movably sleeved between the insides of each group of mounting seats 4, the four limiting rods 3 are divided into two groups, the opposite ends of each group of limiting rods 3 are movably sleeved through the opposite sides of the two slides 201, the rotating rod 6 is movably sleeved between the insides of the two slides 201, and the rotating rod 6 is movably sleeved between the insides of the two brake pads 202.

[0026] The effect achieved is that when it is necessary to use the dispatching winch to move an object, first connect the two motors 205 and the motor 8 to the external controller (PLC controller), then connect the controller to the external power supply, and then install one end of the prepared wire rope inside the drum 7, then wind part of the wire rope around the drum 7, and then install the other end of the wire rope to the object to be moved, and then use the controller to start the motor 8. When the motor 8 is started, the motor 8 will drive the drum 7 to rotate with the cooperation of the two brackets 5 and the rotating rod 6, and the rotating drum 7 will drive the wire rope wound on the drum 7 to reel in, and the continuously reeled wire rope will also drive the object connected to it to move. When an emergency occurs during the operation of the winch, it needs to be quickly When the reel 7 stops rotating at a high speed, the two motors 205 are started simultaneously by the controller. At this time, each started motor 205 will drive the corresponding gear 206 to rotate under the cooperation of the corresponding round rod 207 and the corresponding set of mounting seats 4. At the same time, the rotating gear 206 will drive the corresponding set of racks 204 to move in relative directions. At this time, the two sets of racks 204 moving in relative directions will, under the cooperation of the corresponding set of limiting rods 3 and the two slide grooves 203, allow the two slides 201 to respectively drive the brake pads 202 connected thereto to move relative to each other. When the opposite sides of the two brake pads 202 are in contact with the opposite sides of the reel 7 respectively, the two brake pads 202 in contact with the reel 7 will stop the rotating reel 7. At this time, the two motors 205 can be turned off by the controller.

[0027] Working principle: When it is necessary to use the dispatch winch to move an object, first connect the two motors 205 and the motor 8 to the external controller (PLC controller), then connect the controller to the external power supply, and then install one end of the prepared wire rope inside the drum 7, then wind part of the wire rope around the drum 7, and then install the other end of the wire rope to the object to be moved, and then use the controller to start the motor 8. When the motor 8 is started, the motor 8 will drive the drum 7 to rotate with the cooperation of the two brackets 5 and the rotating rod 6, and the rotating drum 7 will drive the wire rope wound on the drum 7 to reel in, and the continuously reeled wire rope will also drive the object connected to it to move. When an emergency occurs during the operation of the winch, it is necessary to quickly let When the reel 7 stops rotating, the two motors 205 are started simultaneously by the controller. At this time, each started motor 205 will drive the corresponding gear 206 to rotate with the cooperation of the corresponding round rod 207 and the corresponding set of mounting seats 4. At the same time, the rotating gear 206 will drive the corresponding set of racks 204 to move in relative directions. At this time, the two sets of racks 204 moving in relative directions will, with the cooperation of the corresponding set of limit rods 3 and the two slide grooves 203, allow the two slides 201 to respectively drive the brake pads 202 connected thereto to move relative to each other. When the opposite sides of the two brake pads 202 are in contact with the opposite sides of the reel 7 respectively, the two brake pads 202 in contact with the reel 7 will stop the rotating reel 7. At this time, the two motors 205 can be turned off by the controller.
