Specifically, one end of the clamping device 11 is fixedly connected with the slide wire 2, that is, one end of the clamping device 11 close to the slide wire 2 is fixedly connected with the slide wire 2. One end of the clamping device 11 is fixedly connected with the slide wire 2 through a bolt device.
Specifically, two sliding blocks 121 capable of sliding left and right are symmetrically arranged on two sides of the other end of the clamping device 11, that is, the clamping device 11 is vertically arranged above the slide wire 2, and two sliding blocks 121 capable of sliding left and right are symmetrically arranged on two sides of the other end of the clamping device 11, that is, the original end away from the slide wire 2. The middle part of the clamping device 11 is penetrated by the screw 13, so that the middle part of the clamping device 11 is provided with a hole for the screw 13 to penetrate through, and the upper end of the surface where the hole is located is symmetrically provided with two sliding blocks 121 capable of sliding left and right.

The distance between the corresponding slide block 121 on the right side of the screw 13 and the slide block sensing device 123 on the right side of the screw 13 before sliding is also a preset threshold. The slider sensing means 123 and the slider 121 are symmetrically arranged with respect to the clamping means 11.
Specifically, two of the slider sensing devices 123 are respectively provided with an alarm. And any one of the slide block sensing devices 123 gives an alarm through the alarm.
Specifically, the slider sensing device 123 is an infrared alarm. The infrared alarm is divided into an active type and a passive type. The active infrared alarm is characterized in that the alarm actively emits infrared rays, and the infrared rays bounce back when touching obstacles and are received by a probe of the alarm. If the probe detects that the infrared ray is static, namely the infrared ray is continuously emitted and the infrared ray is continuously rebounded, the alarm cannot give an alarm. When a movable object touches the invisible red line, the probe detects the abnormality and gives an alarm. The slider sensing device 123 is an active infrared alarm, when the slider 121 on the left side of the clamping device 11 continues to slide to the left side until the infrared rays emitted by the infrared alarm on the left side of the screw 13 are blocked, the probe of the infrared alarm receives and detects the abnormality, and an alarm is given, that is, the slider sensing device 123 on the left side of the screw 13 gives an alarm. When the slide block 121 on the right side of the clamping device 11 continuously slides to the right side until the infrared ray emitted by the infrared alarm on the right side of the screw rod 13 is blocked, and the infrared alarm is received and detected by a probe of the infrared alarm, the probe detects abnormality and gives an alarm, namely the slide block sensing device 123 on the right side of the screw rod 13 gives an alarm.

The housing is fixedly connected with the slide line 2 through a hanging bracket 15. Two ends of the screw 13 are respectively fixed on the housing through nuts.
Specifically, the screw 13 is provided with an adjusting device, and the adjusting device is used for adjusting the screw 13, so as to adjust the slide wire 2. The adjusting device is a shaking handle connected with one end of the screw 13. When the corresponding slider sensing device 123 gives an alarm, the adjustment of the slide wire 2 is performed by loosening the nuts at the two ends of the screw 13 and then shaking the shaking handle connected with one end of the screw 13 according to the situation of the play of the slide wire 2 observed on site. When the two sliders 121 capable of sliding left and right are returned to the original non-sliding position by shaking the handle, the adjustment of the slide wire 2 is completed. Through the implementation of the monitoring device of the slide wire 2, the on-line leaping position of the slide wire 2 can be more intuitive, the leaping direction can be mastered, a reliable basis is provided for 'state maintenance', and 'periodic maintenance' is converted into 'state maintenance', so that scientific management of the slide wire 2 is realized, and the reliable and safe operation of the system is ensured. Meanwhile, the large-area disassembly of the slide wire 2 joint is reduced in the daily maintenance process, and the daily manual load and the danger of the limb operation are reduced. The monitoring device of the slide wire 2 is simple in structure, convenient to disassemble and assemble, has certain practicability and can be popularized and applied.
Specifically, the adjusting device carried by the screw 13 loosens the fixing nuts at the two ends of the screw 13, so that the slide wire 2 is in a loose state, and meanwhile, the slide wire 2 is relatively displaced by using a left-right push-pull force generated by matching a special screw of the adjusting device with a turbine, so as to adjust a left-right leaping gap, thereby completing the distance over which the slide wire 2 leaps. When the two sliders 121 capable of sliding left and right are returned to the original positions where the sliders do not slide, the adjustment of the slide wire 2 is completed.
The working process of the monitoring device of the slide wire will be explained in detail as follows: the monitoring device is vertically arranged above the slide line, a horizontal monitoring part is arranged on the monitoring device and used for monitoring the inclination of the slide line, and when the inclination monitored by the horizontal monitoring part exceeds a preset threshold value, the horizontal monitoring part gives an alarm. Specifically, the level monitoring part is parallel to the slide line, and the detected inclination of the level monitoring part is the inclination of the slide line. The early slide wire inclination can be quickly and effectively detected, and the normal operation management can be realized by timely maintenance.
In summary, the monitoring device for the slide wire can quickly and effectively detect the inclination of the slide wire in the early stage and timely maintain the slide wire to enable the slide wire to normally operate and manage the slide wire. Effectively overcomes various defects in the prior art and has high industrial utilization value.
