DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0017] Referring to Figures 1 to 4 , the laser ranging device for adjusting the center line of the roller path according to the embodiment of the present invention includes: a laser rangefinder 1, two laser receiving plates 5, and two pointers 4; wherein, the two laser receiving plates 5 are respectively arranged on both sides of the roller path to be adjusted, and the two are symmetrical about the transverse center line of the roller path 3 to be adjusted; the two pointers 4 are arranged on the corresponding laser receiving plates 5 along the transverse center line, and are respectively used to point to the transverse center line of the roller path 3 to be adjusted and be collinear with the transverse center line; the two laser receiving plates 5 are adjustably connected to the base position of the roller path 3 to be adjusted, so that the two pointers 4 coincide with the transverse center line of the roller path 3 to be adjusted; the laser rangefinder 1 is arranged at one end of the roller path 3 to be adjusted along the longitudinal center line direction of the roller path 3 to be adjusted, and is integrally connected to the roller path 3 to be adjusted through a fixing sleeve 18, and is used to measure the distance from the corresponding laser receiving plate 5 after rotating left and right to a preset angle together with the roller path 3 to be adjusted in the same plane.

[0018] Specifically, the laser rangefinder 1 is arranged vertically at one end of the roller path 3 to be adjusted to ensure parallelism with the longitudinal center line of the roller path to be adjusted. The two laser receiving plates 5 are symmetrically arranged on both sides of the roller path 3 to be adjusted to ensure that their respective distances from the laser rangefinder 1 are equal, reducing measurement errors. The laser rangefinder 1 can display corresponding data after completing the distance measurement, enabling the user to directly read the measurement results, which is convenient and fast.

[0019] Pointers 4 are respectively arranged on the two laser receiving plates 5 to respectively point to the transverse center line of the roller path 3 to be adjusted, so that the measurement references on both sides are consistent.

[0020] Guide members can be arranged on the base of the roller path 3 to be adjusted to embed the laser receiving plates 5, so that their positions are adjustable in the horizontal direction, and then the positions of the pointers 4 can be adjusted. Finally, the straight line where the pointers 4 are located coincides with the transverse center line of the roller path, so that the center line of the laser receiving plate 5 and the transverse center line of the roller path 3 to be adjusted are on the same straight line.

[0021] The shape of the fixing sleeve 18 can match the roller path 3 to be adjusted, so as to clamp on the roller path. Then, the laser rangefinder 1 is connected to the fixing sleeve 18 through the connecting seat 2, and the laser rangefinder 1 can be detachably fixed on the roller path 3 to be adjusted. The fixing sleeve 18 can be set in a clamp shape, and a number of fastening bolts are arranged thereon for bolt connection with the roller path 3 to be adjusted.

[0022] Refer to Figure 5 , the fixing sleeve 18 includes: two semi-circular snap rings 18; wherein, connecting plates are respectively arranged at both ends of the two semi-circular snap rings 18 for connecting the two semi-circular snap rings 18 through a number of bolts.

[0023] Furthermore, a connecting seat 2 is arranged at the bottom of the laser rangefinder 1 for connecting with the connecting plate of the fixing sleeve 18.

[0024] Refer to Figure 6 , the connecting seat 2 includes: a clamping groove 16, a fastener 15 and two connecting rods 17; wherein, the two connecting rods 17 are arranged oppositely along the vertical direction and are connected between the two connecting plates at the upper end of the fixing sleeve 18; the clamping groove 16 is arranged at the top of the connecting rod 17, and the fastener 15 is connected to the opening end of the clamping groove 16, and the two cooperate to fix the laser rangefinder 1. The distance between the two connecting rods 17 can be determined according to the actual situation. Connecting holes are correspondingly opened on the two connecting rods 17 for connecting with the two connecting plates at the end of the fixing sleeve 18.

[0025] The shape of the clamping groove 16 matches the contour of the laser rangefinder 1. For example, the clamping groove 16 can be a U-shaped structure with an upward opening. One end of the fastener 15 can be rotatably connected to one side of the opening end of the clamping groove 16, and the other end can be snap-connected to the opening end of the clamping groove 16. The shape and structure of the fastener 15 can be determined according to the actual situation, and this embodiment does not make any limitation on it. By setting the fastener 15, the laser rangefinder 1 can be quickly and stably placed.

[0026] A laser receiving plate 5 is arranged to receive the laser beam emitted by the laser rangefinder 1, so as to measure the distance between the two by using the laser rangefinder 1. When the distance measured when the laser rangefinder 1 rotates to the left side of the roller path (the distance between the laser rangefinder 1 and the left laser receiving plate 5) is the same as the distance measured when it rotates to the right side of the roller path (the distance between the laser rangefinder 1 and the right laser receiving plate 5), it can be determined that there is no deviation in the installation of the roller path 3 to be adjusted in the vertical direction. Otherwise, it is considered that the perpendicularity does not meet the standard, and then the longitudinal center of the roller path needs to be adjusted. Then, the laser rangefinder 1 is used for re-measurement again, and the longitudinal center of the roller path is adjusted again according to the measurement results until the vertical accuracy reaches the allowable range. The laser rangefinder 1 is connected to the roller path 3 to be adjusted through a fixing sleeve 18 and can rotate left and right with the roller path 3 to be adjusted, so as to record a ranging value once when rotating 90° to the left (the vertical distance data between the longitudinal center line and the transverse center line of the roller path), and record a ranging value once when rotating 90° to the right (the vertical distance data between the longitudinal center line and the transverse center line of the roller path). By comparing the two measured values (subtracting the two data), the deviation value of the longitudinal center line of the roller path can be calculated, and then the longitudinal center of the roller path is adjusted according to the deviation value. By using the laser rangefinder 1 to rotate left and right (oscillate) to adjust the deviation of the roller path center line, the measured value accuracy can reach an adjustment accuracy of 0.5 - 0.3 mm.

[0027] Obviously, it can be obtained from the above that in the laser ranging device for adjusting the roller path center line provided in this embodiment, by arranging the laser receiving plates on both sides of the roller path to be adjusted, and using a pointer to adjust the center of the laser receiving plate to coincide with the transverse center line of the roller path, the laser rangefinder is arranged at one end of the roller path to be adjusted along the longitudinal center line direction of the roller path to be adjusted and is connected to the roller path to be adjusted as a whole, so as to measure the distance to the corresponding laser receiving plate after rotating to a preset angle with the roller path to be adjusted, so that the operator can determine the deviation value of the vertical distance between the longitudinal center line and the transverse center line of the roller path according to the measured distance, and then adjust the longitudinal center of the roller path, thereby ensuring the vertical accuracy of the installation of the roller path.

[0028] Refer to Figure 7 , in each of the above embodiments, it further includes: two magnet blocks 8; wherein, the two magnet blocks 8 are magnetically connected to the base 9 of the roller path 3 to be adjusted, and guide blocks 7 are respectively arranged thereon for placing the corresponding laser receiving plate 5 and adjusting the position of the laser receiving plate 5 in the horizontal direction.

[0029] Specifically, the magnet blocks 8 and the guide blocks 7 can be square, rectangular, etc., and their shapes can be the same or different. The length of the guide block 7 can be less than the length of the magnet block 8.

[0030] A guide groove is provided in the guide block 7. The laser receiving plate 5 is embedded in the guide groove and is slidably connected to the guide groove for receiving the rays emitted by the laser rangefinder 1 to measure the distance between it and the laser rangefinder 1. The guide groove in the guide block 7 can be a strip-shaped groove. Adjusting holes 6 are correspondingly provided on the two side walls of the guide block 7 in the width direction to tighten the side wall of the laser receiving plate 5 by adjusting bolts, thereby fixing the laser receiving plate 5.

[0031] Preferably, the horizontal center line of the laser receiving plate 5, the center line of the pointer 4, and the center line of the guide groove are collinearly arranged.

[0032] Refer to Figure 8 , the pointer 4 includes: a needle tube 13 and a needle body 10 and an elastic member 11 placed inside the needle tube; wherein, one end of the needle tube is provided with a connecting member 12 for connecting with the laser receiving plate 5; the first end of the elastic member 11 is connected to a part of the inner wall of the needle tube close to the connecting member 12; One end of the needle body is connected to the second end of the elastic member, and the other end extends to the outside of the needle tube.

[0033] Specifically, the elastic member 11 is a spring. Setting the elastic member 11 can prevent the tip of the pointer 4 from damaging the surface of the roller path. The connecting member is a spherical structure, and a threaded hole can be provided inside it for connecting with the laser receiving plate 5.

[0034] During specific implementation, a theodolite can also be used to cooperate with adjusting the position of the pointer 4 so that its contact head can point to the transverse center line of the roller path.

[0035] The usage method of the distance measuring device provided by the present invention is as follows: Fix the connecting seat 2 of the laser rangefinder 1 on the fixed sleeve 18 with the fastening bolt 14. At the same time, place the laser rangefinder 1 into the card slot 16 of the connecting seat 2, and the fastener 15 clamps the laser rangefinder 1. Place the magnet block 8 (the receiving plate can be quickly installed and disassembled with the magnet block) on the roller path base, then place the two laser receiving plates 5 in the guide grooves on the magnet block, place the pointer 4 on the upper end surface of the laser receiving plate 5, utilize the fact that the laser receiving plate 5 can move horizontally and longitudinally in the guide groove, and at the same time use a theodolite to cooperate with adjusting the pointer 4 to point to the transverse center line of the roller path, and then fix the adjusting bolt. After the adjustment device is installed, rotate the roller path 90° to the left and right for swinging, turn on the rangefinder, record a distance measurement value when rotating 90° to the left, record a distance measurement value when rotating 90° to the right, compare the two measured values, and the deviation value of the longitudinal center line of the roller path can be calculated, thereby adjusting the longitudinal center of the roller path according to the deviation value. Use the laser rangefinder 1 to swing left and right to adjust the center line deviation of the roller path, and the adjustment accuracy of the measured value can reach an accuracy of 0.5 - 0.3 mm.

[0036] In summary, the laser ranging device provided by the present invention for adjusting the center line of the roller path can quickly locate, accurately measure distances, automatically display the measured distance values, and can be reused, improving the installation quality and installation speed of the roller path.
