Description

Technical Field

[0001] The utility model relates to the technical field of adhesive belt machines, in particular to a counterweight auxiliary and detection alarm device for an adhesive belt machine. Background Art

[0002] In the field of coal washing, belt conveyors are the main transportation equipment. During the use of belt conveyors, coal is scattered due to the deviation of the belt. When the scattered materials fall from the upper belt surface to the non-working surface of the lower belt, the materials will enter the tail drum of the belt conveyor as the lower belt surface runs, causing the tail drum to wrap the materials and increase the diameter of the drum. When the diameter of the drum becomes larger, the tension of the belt surface increases, and the belt surface is stretched, which makes the belt break easily. Therefore, counterweight tensioning is needed to solve the problem of belt surface stretching and breakage.

[0003] With the cooperation of counterweight tensioning, when the tension of the tape surface of the material wrapped by the tail roller is too large, the tail counterweight is lifted up under the drive of the head roller of the belt conveyor to make the tape loose and prevent damage to the tape. Usually, the operator needs to clean the material wrapped by the roller after the tail counterweight is lifted, and the operator needs to use the fall chain to pull the counterweight down slowly to restore the normal tension of the tape. When the belt surface of the belt conveyor is torn longitudinally or reaches the end of its service life and needs to be replaced, the operator usually needs to use the fall chain to lift the tail counterweight to relax the tape tension to replace the tape. After the replacement is completed, the fall chain is operated again to lower the counterweight to restore the normal tension of the belt conveyor. When cleaning the material wrapped by the roller and replacing the tape, the cooperation of the operator is required. Relying on manpower to solve the problem is inefficient and has high labor intensity for the operators. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1 As shown, the belt conveyor counterweight auxiliary and detection alarm device includes a track 1, a tension frame 2, a tail roller 13, a hanger 5, a first traction rope 7, and a counterweight 8;

[0023] A tensioning frame 2 is slidably provided on the track 1, a vertically arranged guide wheel bracket 3 is fixed at the end of the track 1, and a first guide wheel 4 is rotatably connected to the guide wheel bracket 3;

[0024] The bottom end of the hanger 5 is rotatably connected to a second guide wheel set 6;

[0025] One end of the first traction rope 7 is fixedly connected to the tension frame 2, and the other end of the first traction rope 7 is fixedly connected to the top of the counterweight 8 via the first guide wheel 4 and the second guide wheel group 6 respectively;

[0026] A tail cylinder 9 is provided between the tensioning frame 2 and the guide wheel bracket 3. The fixed end of the tail cylinder 9 is hinged to the guide wheel bracket 3, and the telescopic end of the tail cylinder 9 is connected to the tensioning frame 2 through a first zipper 10. The function of the tail cylinder 9 is to facilitate the pulling of the tensioning frame 2 to move, thereby moving the tail roller 13 back and forth, thereby achieving tensioning and relaxation of the tape surface, facilitating the replacement of the tape or cleaning the material wrapped by the tail roller 13, and resuming normal production.

[0027] A lifting cylinder 11 is provided between the hanger 5 and the counterweight 8. The fixed end of the lifting cylinder 11 is fixedly connected to the hanger 5, and the telescopic end of the lifting cylinder 11 is fixedly connected to the top of the counterweight 8 through a second zipper 12. The lifting cylinder 11 is used to achieve the up and down traction effect on the counterweight 8. The up and down movement of the counterweight 8 and the cooperation of the tail cylinder 9 can realize the forward and backward movement of the tensioning frame 2.

[0028] When the belt surface of the belt conveyor is torn longitudinally or reaches the end of its service life and needs to be replaced, the counterweight 8 can be quickly lifted up by the lifting cylinders 11 on both sides of the counterweight 8 to loosen the tail roller 13 and the tape, saving the labor intensity of the operators. The operators can replace the tape or handle the wrapped materials. After the operation is completed, the counterweight 8 can be quickly lowered by the lifting cylinder 11, and with the cooperation of the tail cylinder 9, the tail roller 13 is moved, and the tape surface is restored to a tensioned state, and normal production can be carried out.

[0029] The counterweight 8 includes a counterweight block 81 and a counterweight guide frame 82 above the counterweight block 81. A third guide wheel 83 is rotatably connected inside the counterweight guide frame 82. The top of the counterweight block 81 is fixedly connected to the counterweight guide frame 82 via a second traction rope 84 that passes around the third guide wheel 83.

[0030] A bearing shoe seat 18 is fixed on the tension frame 2, and a tail drum 13 is rotatably connected to the bearing shoe seat 18.

[0031] A stall switch 14 is fixed on the bearing shoe seat 18, and the trigger end of the stall switch 14 is arranged opposite to the tail roller 13. The stall switch 14 can detect the rotation of the tail roller 13 of the belt conveyor in real time, and further judge whether the tape surface is loose and slipping, the tail roller 13 stops rotating, and other abnormal problems.

[0032] A displacement sensor 17 is also fixed between the hanger 5 and the counterweight 8, and a controller 15 is also included. Preferably, the controller 15 adopts a Milant XSA displacement digital display. The stall switch 14 and the displacement sensor 17 are electrically connected to the input end of the controller 15 respectively, and the output end of the controller 15 is electrically connected to the belt conveyor stop button 16.

[0033] When the diameter of the tail drum 13 increases after the coal is spread on the belt conveyor, and the tail counterweight 8 is automatically lifted, the tail drum 13 will move forward under the action of the belt and the material. At this time, the displacement sensor 17 is triggered during the upward movement of the counterweight guide frame 82, so that the pull rod of the displacement sensor 17 is retracted, and the detected movement value is fed back to the controller 15 through the displacement sensor 17. If the counterweight 8 is lifted upward after the tail drum 13 wraps the material and the distance exceeds the preset value of the controller 15, the controller 15 controls the belt conveyor stop button 16 to be triggered, and the belt conveyor stops working. The operator can clean up the material wrapped in the tail drum 13 in time; during the normal operation of the belt conveyor, when the belt is torn or the tension decreases due to the service life of the belt, the counterweight 8 will fall downward, and the displacement sensor 17 moves downward with the counterweight guide frame 82. When the falling distance exceeds the preset value of the controller 15, the controller 15 controls the belt conveyor stop button 16 to be triggered, and the operator can check whether the belt is torn and can repair it in time.

[0034] The specific operation process of this embodiment is as follows:

[0035] When the tape machine is in a normal state, the tail cylinders 9 on both sides of the tension frame 2 extend to keep the first zipper 10 in a relaxed state, and the lifting cylinders 11 on both sides of the counterweight 8 extend to keep the second zipper 12 in a relaxed state. If the tail roller 13 moves forward, the first zipper 10 will not affect the movement of the tail roller 13. If the tail roller 13 moves backward, the second zipper 12 will not affect the descent of the counterweight 8.

[0036] When the diameter of the tail drum 13 increases after the coal is spread on the belt conveyor, and the tail counterweight 8 is automatically lifted, the tail drum 13 will move forward under the action of the belt and the material. At this time, the displacement sensor 17 is triggered during the upward movement of the counterweight guide frame 82, so that the pull rod of the displacement sensor 17 is retracted, and the detected movement value is fed back to the controller 15 through the displacement sensor 17. When the counterweight 8 is lifted upward after the tail drum 13 wraps the material and the distance exceeds the preset value of the controller 15, the controller 15 controls the belt conveyor stop button 16 to be triggered, and the belt conveyor stops working. The operator can clean the material wrapped in the tail drum 13 in time. After the operator cleans the material wrapped in the tail drum, when the tail drum 13 needs to be pulled back to move, the tail cylinders 9 on both sides of the tensioning frame 2 can be retracted to assist the counterweight 8 to descend. When the belt reaches the normal operating tension, the tail cylinders 9 on both sides are extended to keep the first zipper 10 relaxed.

[0037] When the tape is torn or the tension decreases due to the end of its service life, the counterweight 8 will fall downward, and the displacement sensor 17 will move downward with the counterweight guide frame 82. When the descending distance exceeds the preset value of the controller 15, the controller 15 controls the tape machine stop button 16 to be triggered, and the tape machine stops working. The operator can check whether the tape is torn and can repair it in time. When the tape needs to be replaced, the lifting cylinders 11 on both sides of the counterweight guide frame 82 can be retracted, and the counterweight 8 can be lifted upward. Under the action of the second zipper 12, the tape is relaxed, and the tail cylinder 9 is extended. When the tape is replaced and needs to be tensioned, the tail cylinders 9 on both sides of the tensioning frame 2 can be retracted to tighten the first zipper 10, and the cylinders on both sides of the counterweight guide frame 82 can be extended to move the tensioning frame 2 toward the counterweight 8. After the tape tension is normal, the tail cylinders 9 on both sides of the tensioning frame 2 are extended to keep the first zipper 10 in a relaxed state.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
