[0002] Bucket wheel stacker reclaimer refers to a kind of high-efficiency loading and unloading machinery for continuous conveying that can both stack and retrieve materials in large dry bulk cargo yards. It consists of a belt conveyor arm that can pitch and swing horizontally and a bucket wheel, frame and operating mechanism at its front end. The belt can run in both directions. When retrieving materials, the bucket wheel takes the materials and sends them out through the conveyor arm. When stacking materials, the goods transported by the main conveyor are thrown into the yard through the conveyor arm. The belt conveyor arm mainly consists of the following parts: drive device, tensioning device, redirecting device, upper and lower roller groups, frame, conveyor belt, etc. Through the study of the working principle and working mode of bucket wheel stacker reclaimer, it is found that during the stacking operation of the stacker reclaimer, there will be a situation where there is not always material on the conveyor belt. Especially for the start-stop process and process failure, the cantilever belt will run no-load for a long time. The cantilever belt can be decelerated by setting the material flow switch to reduce the power consumption when the belt is running no-load, so as to achieve the purpose of energy saving.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] See also Figure 1-Figure 5The utility model provides a technical solution: a bucket wheel machine cantilever speed reduction energy-saving device, comprising a bottom plate 1, a speed reduction mechanism 2 is fixedly installed on the top of the bottom plate 1, the speed reduction mechanism 2 comprises a rotating seat 201 and a travel switch 204, the rotating seat 201 is fixedly installed on the top of the bottom plate 1, the inner side of the rotating seat 201 is rotatably connected with a rotating rod 202 through a pin shaft, the right end of the rotating rod 202 is fixedly installed with a running wheel 203, the outer sliding of the travel switch 204 is provided with a protective structure 205, and the protective structure 205 is fixedly installed on the bottom plate 1. At the top of the bottom plate 1, a switch connector 207 is provided between the left end of the rotating rod 202 and the travel switch 204. A counterweight ring 206 is provided on the outer wall of the rotating rod 202. The counterweight ring 206 is close to the left end of the rotating rod 202. The travel switch 204 is electrically connected to a wire connector 208 through a cable. The wire connector 208 is fixedly mounted on the top of the bottom plate 1. The wire connector 208 is electrically connected to the controller of the conveyor belt through wires. The running wheel 203 is located below the pressure wheel belt. When the tail car belt is running without load, the tail car belt is electrically connected to the conveyor belt. The pressure wheel belt near the belt pressure wheel device will be lifted and will not move on the roller frame. When there is material on the belt on the ground, the pressure wheel belt will be pressed down by the material to the roller for movement, and then judge whether there is material on the belt. After the pressure wheel belt is pressed on the running wheel 203, the left end of the rotating rod 202 will be tilted, and then the travel switch 204 will be pulled to open through the switch connector 207. Because the travel switch 204 is electrically connected to the controller of the conveyor belt through the wire connector 208, the conveyor belt is started to accelerate to The feeding speed is to prevent the material from piling up at the end of the tail car belt. When there is no material on the belt, the pressure wheel belt rises, and the counterweight ring 206 is used to drive the left end of the rotating rod 202 to lower, and then the travel switch 204 is pulled closed through the switch connector 207, so as to achieve the purpose of controlling the acceleration and deceleration of the feeding belt. The protective structure 205 is set to protect the travel switch 204 to prevent the left end of the rotating rod 202 from tilting to a large extent, resulting in the switch connector 207 being unable to connect the left end of the rotating rod 202 and the travel switch 204;

[0021] The protection structure 205 includes a slide rail 2051, which is slidably sleeved on the outer wall of the travel switch 204. A spring 2052 is fixedly installed on the top inner wall of the slide rail 2051. The bottom end of the spring 2052 is fixedly connected to the top of the travel switch 204. The slide rail 2051 is set to limit the travel switch 204, so that the travel switch 204 can only slide up and down relative to the bottom plate 1. The spring 2052 is set to push the travel switch 204 to move downward, so as to avoid excessive freedom of the travel switch 204, which causes the switch connector 207 to be unable to open and close the travel switch 204;

[0022] The switch connector 207 includes a rotating plate 2071 and a collar 2072. The rotating plate 2071 is rotatably arranged on the right outer wall of the travel switch 204 through a pin shaft. The collar 2072 is fixedly installed on one end of the rotating plate 2071, and the other end of the rotating plate 2071 is connected to the switch of the travel switch 204. The collar 2072 is movably sleeved on the left end of the rotating rod 202. The rotating plate 2071 is arranged to connect the switch on the travel switch 204 and the collar 2072. The left end of the rotating rod 202 and the rotating plate 2071 are connected through the collar 2072, so that when the left end of the rotating rod 202 is tilted, the rotating plate 2071 can be driven to rotate, thereby turning on the travel switch 204. When the left end of the rotating rod 202 is lowered, the rotating plate 2071 can be driven to reverse, thereby turning off the travel switch 204.

[0023] Two deceleration mechanisms 2 are provided, and even if one deceleration mechanism 2 is not sensed or damaged, the acceleration can be ensured all the time, thereby improving safety. A protective shell 3 is fixedly installed on the top of the bottom plate 1, and the protective shell 3 covers the deceleration mechanism 2. A through slot 4 is provided on the right outer wall of the protective shell 3, and the through slot 4 corresponds to the rotating rod 202. The protective shell 3 is provided to protect the deceleration mechanism 2 to prevent the falling materials from hitting the travel switch 204, and the through slot 4 is provided so that the rotating rod 202 can rotate normally.

[0024] A counterweight 5 is fixedly mounted on the top of the travel switch 204, which is used to press down the travel switch 204, so that the travel switch 204 will squeeze the spring 2052 to move upward only when it is subjected to sufficient upward thrust;

[0025] An upper limit block 6 and a lower limit block 7 are fixedly installed on the right outer wall of the limit switch 204. The upper limit block 6 and the lower limit block 7 are respectively located above and below the rotating plate 2071. The upper limit block 6 and the lower limit block 7 are set to limit the maximum rotation angle of the rotating plate 2071 to prevent the rotating plate 2071 from rotating too much, which may cause the rotating plate 2071 to be disconnected from the switch on the limit switch 204.

[0026] Working principle: When in use, the base plate 1 is installed on the cantilever frame, and then the running wheel 203 is extended under the pressure wheel belt, and the wire connector 208 is electrically connected to the controller of the feed belt using wires. When there is no material on the feed belt, the pressure wheel belt rises, and at this time the travel switch 204 is closed, causing the feed belt to slow down or stop. After there is material on the feed belt, the pressure wheel belt presses the running wheel 203 down, causing the left end of the rotating rod 202 to tilt up, and then the traction ring 2072 to tilt up. The lifting of the ring 2072 causes the rotating plate 2071 to rotate, and then the travel switch 204 is turned on, causing the conveyor belt to accelerate to the corresponding speed for feeding.

[0027] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
