Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of equipment for auxiliary application of portable inclinometers, in particular to a wire winding mechanism for a portable inclinometer. Background Art
[0002] In construction projects such as deep foundation pit enclosure, dam and landslide monitoring, inclinometers are used to monitor soil displacement and deformation. A portable inclinometer consists of a controller, a wire rope, an inclinometer sensor, etc. During measurement, the controller controls an electric wire winding device to lower the sensor (the sensor has two pairs of upper and lower tension rollers to ensure that the axial direction of the sensor is parallel to the axial direction in the inclinometer tube) into the bottom of the inclinometer tube (a conduit with a limit groove) through the wire rope, and then lift the relevant system of the sensor and read the sensor data every 500 mm (the inclination angle of the inclinometer tube axis relative to the plumb line). The internal system of the controller calculates the horizontal displacement value of each section based on the section length and the inclination angle, and then obtains the deformation value of the entire inclinometer tube.
[0003] The main structure of the existing electric wire winding device supporting the inclinometer controller includes a motor, a winding disc, and a frame. The motor and the winding disc are installed on the frame. After the motor drives the winding disc to rotate, the wire rope connecting the controller and the sensor can be wound or unwound. Although the existing electric wire winding device meets the effect of winding and unwinding the wire rope to a certain extent, due to structural limitations, there are still the following technical drawbacks. Specifically, the depth of the inclinometer tube is relatively deep and the length of the wire rope is relatively long (up to dozens or hundreds of meters). Since the winding disc and the wire rope cannot move left and right, when the wire rope is wound, it will be concentrated at a fixed position on the winding disc, and the wire rope cannot be normally wound at other positions of the winding disc, resulting in the wire rope being unevenly wound on the winding disc from left to right. Even after winding to a certain extent, the wire rope will jump out of the baffle plates on both sides of the winding disc, which has an adverse effect on the work of winding and unwinding the wire rope. In summary, it is particularly necessary to provide a wire winding mechanism that can wind and unwind the wire rope neatly between the sensor and the controller. Summary of the Utility Model
[0004] In order to overcome the drawbacks of the existing electric wire winding device for inclinometers, due to structural limitations, the wire rope cannot be normally wound at other positions of the winding disc, resulting in the wire rope being unevenly wound on the winding disc after being wound, and even after winding to a certain extent, the wire rope will jump out of the baffle plates on both sides of the winding disc, which has an adverse effect on the work of winding and unwinding the wire rope, the utility model provides a wire winding mechanism for a portable inclinometer. Under the combined action of relevant mechanisms, when the winding disc winds the wire rope, the sliding guide mechanism will move left and right to drive the wire rope to move, so that the wire rope can be wound on the winding disc from right to left and from left to right in turn, the wire rope can be neatly wound on the winding disc, and the wire rope is prevented from jumping out of the winding disc.

The middle part of the winding reel is fixedly installed on the outer end of the rotating shaft of the motor reduction device and is located between the inner ends of the two fixed frames. One end of the wire feeding rope of the inclinometer is fixedly installed on the outer middle part of the outer side of the winding reel, and the wire feeding rope is led out from the upper rear side of the pulley groove of the pulley and then outwards and downwards.
[0007] Further, the outer diameter of the middle part of the winding reel is smaller than the outer diameters of the two ends, and the interval distances between the two outer ends of the winding reel and the inner sides of the two fixed frames.

In this way, the wire rope can be neatly wound on the winding disc, and the wire rope is prevented from jumping out of the winding disc. To sum up, the present novel type has good application prospects. Description of the Drawings

There are openings in the lower parts of the rear ends of the two fixed frames 5.

A sliding ejector rod 82 is installed in the threaded seat 88 through threads.

The outer diameter of the driving pulley 3 is smaller than that of the driven pulley 6 (the outer diameter ratio is 1:5). The inner diameter of the sliding tube 85 in the middle of the inner sides of the two limiting wheels 84 is slightly larger than the outer diameter of the reciprocating lead screw 83 (1 mm), and the outer diameter of the shaft rod 7 is smaller than the inner diameters of the shaft holes at both ends of the rear side of the connecting plate 87.

The lower ends of the two fixing brackets 5 are provided with a support platform (not shown in the figure).
[0019] Figure 1 , 2 , as shown in Figures 3 and 4, when the present invention works, after the motor speed reduction device 1 (after the reverse power switch is toggled forward or backward, the rotating shaft of the motor speed reduction device 1 rotates clockwise or counterclockwise) is powered on, its rotating shaft drives the driven pulley 6 to rotate clockwise or counterclockwise through the driving pulley 3 and the transmission belt 4, and the winding reel 2 synchronously winds or unwinds the wire rope 9. The wire rope drives the sensor at its lower end to rise or fall in height (the wire rope moves up or down along the chute of the pulley). The power output by the rotating shaft of the motor speed reduction device is decelerated by the driven pulley 6, and the reciprocating lead screw 83 rotates clockwise or counterclockwise. When the reciprocating lead screw 83 rotates clockwise, the lower end of the sliding ejector rod 82 of the sliding block will move from right to left along the forward thread groove 831 of the reciprocating lead screw 83. When the sliding block moves to the left stop point, the lower end of the sliding ejector rod 82 of the sliding block will move from left to right along the reverse thread groove 831 of the reciprocating lead screw 83. The above process is continuously cycled, and the sliding block will drive the connecting plate 87 and the pulley 81 to move left and right reciprocally. Subsequently, it drives the wire rope to move left and right reciprocally. Furthermore, it can enable the wire rope to be reciprocally wound from right to left and from left to right in sequence on the middle winding part of the winding reel. In this way, the wire rope can be neatly wound on the winding reel and prevent the wire rope from jumping out of the winding reel. The present invention overcomes the drawbacks of the existing electric wire winding device of the inclinometer. Due to structural limitations, the wire rope cannot be normally wound at other positions of the winding reel, resulting in the wire rope being wound unevenly on the winding reel. Even after being wound to a certain extent, the wire rope jumps out of the baffles at both ends of the winding reel, which has an adverse impact on the work of winding the wire rope.
