[0013] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0014] REFERENCE Figure 1 A broken shaft alarm device for a chain type equipment transmission shaft 1, comprising a transmission shaft 1, a plurality of detection rods 2 are fixedly arranged on the outer side of the transmission shaft 1, a plurality of U-shaped detection switches 3 are fixedly installed on the lower side of the transmission shaft 1 through mounting seats, and the U-shaped detection switches 3 are electrically connected with an alarm 4.

[0015] In view of the problems that the existing transmission shaft 1 of the chain type equipment has broken shaft and it is difficult to troubleshoot the broken shaft, the technical scheme sets a broken shaft detection device for the transmission shaft 1, specifically, the detection rod 2 is fixedly installed on the outer side of the transmission shaft 1, the U-shaped detection switch 3 is correspondingly installed on the lower side of the detection rod 2, the detection rod 2 can be driven to rotate when the transmission shaft 1 rotates normally, the detection rod 2 passes through the U-shaped detection switch 3, the running state of the transmission shaft 1 can be detected through the U-shaped detection switch 3, when the transmission shaft 1 is broken, the detection rod 2 cannot pass through the U-shaped detection switch 3, at this time, the transmission of the transmission shaft 1 fails, the U-shaped detection switch 3 transmits information to the alarm 4, and the alarm 4 generates an alarm, so that the position of the broken shaft can be timely excluded.

[0016] In the scheme, the central control system can obtain the torque of the transmission system, the U-shaped detection switch 3 can also obtain the frequency of the detection rod 2 passing through the U-shaped detection switch 3 when detecting the rotation of the transmission shaft 1, and the running stability of the transmission shaft 1 can be detected by comparing the torque of the transmission system and the running frequency of the detection rod 2.

[0017] Further, there is a gap between the upper end of the U-shaped detection switch 3 and the transmission shaft 1, and the lower end of the detection rod 2 extends into the U-shaped groove of the U-shaped detection switch 3.

[0018] Through the technical scheme, the upper end of the U-shaped detection switch 3 is spaced from the transmission shaft 1, and the two are as close as possible without touching, and the detection rod 2 is as short as possible while ensuring that it can extend into the inside of the U-shaped detection switch 3, thereby reducing the wind resistance of the detection rod 2 during rotation.

[0019] Further, the detection rod 2 is arranged in the radial direction of the transmission shaft 1, and the detection rod 2 is a smooth round rod.

[0020] Through the technical scheme, the detection rod 2 is a smooth round rod, which is used to reduce the running resistance of the detection rod 2.

[0021] Further, the detection rod 2 is fixed on the transmission shaft 1 by a shaft sleeve.

[0022] The detection rod 2 is fixedly installed on the transmission shaft 1 by a shaft sleeve, which is convenient for installation and fixation, and can be easily removed. The detection rod 2 itself can be a conductor, and the U-shaped detection switch 3 is an electromagnetic induction type. The detection rod 2 recognizes the passing of the detection rod 2 through the electromagnetic induction of the U-shaped detection switch 3. In another embodiment, the U-shaped detection switch 3 is installed with an object recognition sensor, and the rotation of the detection rod 2 is sensed by machine vision.

[0023] Further, the alarm 4 is an audible and visual alarm 4.

[0024] Through the technical scheme, the audible and visual alarm 4 can respond in time when the transmission shaft 1 is broken, and the audible and visual alarm 4 can remind workers to check by emitting sound and light information, so as to quickly find the broken transmission shaft 1.

[0025] Working principle: The transmission shaft 1 is fixedly installed with the detection rod 2 on the outer side, and the lower side of the detection rod 2 is correspondingly installed with the U-shaped detection switch 3. The transmission shaft 1 can drive the detection rod 2 to rotate, thereby driving the detection rod 2 to pass through the U-shaped detection switch 3, and finally detecting and judging the running state of the transmission shaft 1 through the U-shaped detection switch 3. When the U-shaped detection switch 3 cannot sense the rotation of the detection rod 2, the alarm 4 issues an alarm to timely remind workers to determine the broken shaft position, and timely repair the broken shaft, thereby avoiding the blocking of the silicon wafer on the equipment line, and greatly reducing the production loss.
