Description

Belt fracture alarm device

Technical Field

The utility model relates to a belt fracture alarm device.

Background

At present, a great number of apparatuses and devices use belts as a transmission mode, and the transmission mode mostly comprises the belts, guide wheels and tension wheels. In order to beautify the mechanical structure, the belt is often hidden, so that an operator can not know the use condition of the belt, and generally only when the machine is difficult to operate normally, the operator can find that the belt is broken and cannot find the condition in time, and therefore the belt breakage alarm device is provided for solving the problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome current operating personnel can in time discover belt fracture defect and the belt fracture alarm device who provides.

The technical scheme for realizing the purpose is as follows: the belt breakage alarm device comprises a tension wheel, wherein a bearing sleeve is sleeved on the outer side wall of the tension wheel; a magnet mounting hole is formed in the front side wall of the bearing sleeve, and a magnet is mounted in the magnet mounting hole; one end of the rotating object stalling detector is connected with the magnetic switch, and the other end of the rotating object stalling detector is connected with the audible and visual alarm; the magnetic switch is arranged right in front of the rotation path of the magnet; and the outer side wall of the bearing sleeve is provided with a bearing sleeve hoop.

Preferably, the magnetic switch is spaced from the magnet.

Preferably, the magnet mounting hole is formed in the edge of the front side wall of the bearing sleeve.

Preferably, the two groups of bearing sleeve clamps are respectively arranged at the front end and the rear end of the outer side wall of the bearing sleeve.

Preferably, the rotating object stalling detector is electrically connected with the audible and visual alarm; the rotating object stall detector is electrically connected with the magnetic switch.

The beneficial effects of the utility model are that: through setting up the bearing housing, lateral wall connects magnet before the bearing housing, magnetic switch is connected to the one end of rotatory object stall detector, audible-visual annunciator is connected to the other end, through the corresponding continuous actuation of magnet and magnetic switch, send operating signal to in the rotatory object detection device, when the belt fracture, tight pulley disappears because belt tension, can't drive rotation and stall, magnet stops and can't change the on-off state through magnetic switch, thereby can't provide the signal of law and trigger audible-visual annunciator, thereby can in time discover the inside belt fracture of machine through audible-visual annunciator with this.

Detailed Description

The technical solution of the present invention will be clearly and completely described with reference to the accompanying drawings. In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance.

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1-2, a belt breakage warning device includes a tension roller 1, and a bearing sleeve 2 is sleeved on an outer side wall of the tension roller 1; a magnet mounting hole 4 is formed in the front side wall of the bearing sleeve 2, and a magnet 5 is mounted in the magnet mounting hole 4; one end of the rotating object stalling detector 7 is connected with the magnetic switch 6, and the rotating object stalling detector 7 is an existing device, for example, the type GYJ-0163-C is adopted; the other end of the rotating object stalling detector 7 is connected with an audible and visual alarm 8; the audible and visual alarm 8 is an existing device, for example, the type is ND16-22FS 24V; the magnetic switch 6 is arranged right in front of the rotation path of the magnet 5; the outer side wall of the bearing sleeve 2 is provided with a bearing sleeve hoop 3. The magnetic switch 6 is spaced from the magnet 5 by a distance of 0.5 cm. The magnet mounting hole 4 is arranged at the edge of the front side wall of the bearing sleeve 2. The bearing sleeve clamps 3 are two sets of clamps which are respectively arranged at the front end and the rear end of the outer side wall of the bearing sleeve 2. The rotating object stalling detector 7 is electrically connected with the audible and visual alarm 8; the rotating-object stalling detector 7 is electrically connected to the magnetic switch 6. The special bearing sleeve 2 is sleeved on the tension wheel 1 of the belt to replace the tension wheel 1 to be driven by the belt, when the belt normally works, the bearing sleeve 2 normally rotates, the magnet 5 on the bearing sleeve 2 rotates along with the rotation, the magnetic switch 6 correspondingly and continuously attracts, the attraction serves as a signal of normal work, the working signal is sent to the rotating object stalling detector 7, when the belt is broken, the tension wheel 1 disappears due to the tension of the belt, the rotation cannot be driven to stop rotating, the magnet 5 stops passing through the magnetic switch 6, the on-off state cannot be changed, and therefore the audible and visual alarm 8 cannot be triggered by signals of rules.

The working principle is as follows: the belt tensioning device is characterized in that a special bearing sleeve 2 is sleeved on a tensioning wheel 1 of the belt to replace the tensioning wheel 1 to be driven by the belt, when the belt works normally, the bearing sleeve 2 rotates normally, a magnet 5 on the bearing sleeve 2 rotates along with the rotation, a magnetic switch 6 is attracted continuously correspondingly to serve as a signal of normal work, the working signal is sent to a rotating object stop detector 7, when the belt is broken, the tensioning wheel 1 stops rotating due to the fact that the tension of the belt disappears, the rotation cannot be driven to stop rotating, the magnet 5 stops passing through the magnetic switch 6, and therefore the on-off state cannot be changed, and therefore a regular signal cannot be provided to trigger an audible and visual alarm 8.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications or substitutions do not depart from the scope of the invention in its corresponding aspects.
