Abstract
The utility model discloses a belt longitudinal crack early warning device of a belt conveyor, which comprises a horizontally installed belt conveyor, wherein a balance plate is horizontally arranged between an ascending belt and a descending belt of the belt conveyor, the cross section of the balance plate is arc-shaped, the balance plate is gradually reduced from the center to two sides, a sleeve is installed at the center position of the bottom end of the balance plate, a rotating shaft is inserted in the sleeve and penetrates through the sleeve, the rotating shaft is rotatably connected with the sleeve through a bearing, and stand columns are vertically and downwards installed at two ends of the rotating shaft; the utility model has the advantages that: the utility model discloses at band conveyer's conveyor belt's below design balance plate device, take place to indulge when the belt and split, buggy or fritter coal can more enter the balance plate device promptly, make the balance plate take place to rotate and trigger proximity switch to make the alarm take place to pipe the warning, the warning staff is timely maintains, prevents that the belt from indulging the fracture by a large scale, avoids big economic loss, is worth using widely on a large scale.
Description
The technical field is as follows:
the utility model relates to a coal dressing equipment technical field especially relates to a band conveyer's belt rip crack early warning device.
Background art:
the technical field of coal dressing, lump coal usually uses band conveyer to carry, because various reasons, sharp-pointed stereoplasm article may be mixed in the lump coal, for example steel spare and other bold debris that drop into on the mechanical equipment in the material processing transportation, these sharp-pointed stereoplasm articles are very likely to pierce through conveyor belt, lead to conveyor belt to produce the rip, the crack is generally only several centimetres or tens of centimetres at the initial stage, the rip phenomenon at this moment is difficult to discover, in case the rip size develops to tens of metres or even hundreds of metres will be difficult to restore, change time is long, cause long-time shut down, cause huge loss, consequently wait to design a detection alarm device that the belt rip takes place the initial stage urgently to avoid the loss.
The utility model has the following contents:
an object of the utility model is to provide a band conveyer's belt is indulged and is split early warning device.
The content of the utility model is as follows: a belt longitudinal crack early warning device of a belt conveyor comprises the belt conveyor which is horizontally installed, a balance plate is horizontally arranged between an ascending belt and a descending belt of the belt conveyor, the cross section of the balance plate is arc-shaped, the balance plate is gradually reduced from the center to two sides, a sleeve is installed at the center of the bottom end of the balance plate, a rotating shaft is inserted in the sleeve and is rotatably connected with the sleeve through a bearing, stand columns are vertically and downwards installed at two ends of the rotating shaft, spring plates are radially and outwards installed at two sides of the rotating shaft, a compression spring is installed on each spring plate, the top end of each compression spring is in contact with the bottom end of the balance plate, proximity switches are arranged under two ends of the balance plate and are fixedly installed on an installation plate, and the installation plate is fixedly installed on a rack of the belt conveyor, the proximity switch is electrically connected with the controller, the controller is electrically connected with the alarm, and the alarm is fixedly installed on the rack of the belt conveyor.
Further, a vibration motor is mounted on the upright post.
The utility model has the advantages that: the utility model discloses at band conveyer's conveyor belt's below design balance plate device, take place to indulge when the belt and split, buggy or fritter coal can fall into the balance plate device promptly, make the balance plate take place to rotate and trigger proximity switch to make the alarm take place to pipe the warning, warning staff's timely maintenance prevents that the belt from indulging the split by a large scale, avoids big economic loss, is worth using widely on a large scale.
Description of the drawings:
fig. 1 is a perspective view of the present invention;
FIG. 2 is a control diagram of the present invention;
in the figure, a belt conveyor 1, a balance plate 2, a sleeve 3, a rotating shaft 4, an upright post 5, a spring plate 6, a compression spring 7, a proximity switch 8, a controller 9, an alarm 10 and a vibrating motor 11.
The specific implementation mode is as follows:
as shown in fig. 1 and 2, a belt longitudinal crack early warning device of a belt conveyor comprises a horizontally installed belt conveyor 1, a balance plate 2 is horizontally arranged between an ascending belt and a descending belt of the belt conveyor 1, the cross section of the balance plate 2 is arc-shaped, the balance plate 2 gradually decreases from the center to two sides, a sleeve 3 is installed at the center of the bottom end of the balance plate 2, a rotating shaft 4 is inserted into the sleeve 3, the rotating shaft 4 is rotatably connected with the sleeve 3 through a bearing, upright columns 5 are vertically installed downwards at two ends of the rotating shaft 4, spring plates 6 are installed radially outwards at two sides of the rotating shaft 4, compression springs 7 are installed on the spring plates 6, the top ends of the compression springs 7 are in contact with the bottom end of the balance plate 2, proximity switches 8 are installed right below two ends of the balance plate 2, the proximity switch 8 is fixedly installed on an installation plate, the installation plate is fixedly installed on a rack of the belt conveyor 1, the proximity switch 8 is electrically connected with a controller 9, the controller 9 is electrically connected with an alarm 10, and the alarm 10 is fixedly installed on the rack of the belt conveyor 1; a vibration motor 11 is mounted on the column 5.
The working principle is as follows: when the belt is longitudinally cracked, pulverized coal or coal blocks fall into the balance plate 2 from the crack, due to the action of the vibration motor 11, the pulverized coal or the coal blocks slide up and down to the bottom end of the balance plate 2 on the balance plate 2, so that the balance plate 2 rotates to trigger the proximity switch 8, the proximity switch 8 sends a signal to the controller 9, and the controller 9 controls the alarm 10 to give an alarm to remind a worker of repairing the longitudinally cracked belt in time.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
