[0003] In the prior art, a fully manual method is used to calibrate whether the relative position between the return rope wheel and the first beam or the second beam is accurate.

DETAILED DESCRIPTION
[0028] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific embodiments:
[0029] Example 1
[0030] like Figures 1 to 3 As shown, the present invention discloses a return rope wheel 54 calibration system, comprising: a base 1, a first positioning fixture 2, a second positioning fixture 3, a calibration beam 4 and a measuring tool (not shown in the figure); the base 1 supports a first beam 51 and a second beam 52, one end of the first beam 51 and one end of the second beam 52 are positioned and clamped by the first positioning fixture 2, and the other end of the first beam 51 and the other end of the second beam 52 are positioned and clamped by the second positioning fixture 3, the first positioning fixture 2 and the second positioning fixture 3 are used to make the first beam 51 and the second beam 52 parallel to each other; the return rope wheel 54 is installed on the first beam 51 and the second beam 52 through a guide shaft 53, two calibration beams 4 parallel to each other are installed on the first positioning fixture 2 and the second positioning fixture 3, and the two calibration beams 4 are respectively located beside the two end surfaces of the return rope wheel 54; the measuring tool is used to measure the distance between each end surface of the return rope wheel 54 and the calibration beam 4.
[0031] The first positioning fixture 2 and the second positioning fixture 3 both include: a positioning body 20, a first clamping mechanism 21 and a second clamping mechanism 22. The positioning body 20 is provided with a first side positioning surface 203 and a second positioning surface. The first side positioning surface 203 is used to be in close contact with the first beam 51, and the second side positioning surface 204 is used to be in close contact with the second beam 52. The first side positioning surface 203 and the second side positioning surface 204 are parallel to each other. The first clamping mechanism 21 and the second clamping mechanism 22 are installed on the positioning body 20. The first clamping mechanism 21 is used to press the first beam 51 against the first side positioning surface 203, and the second clamping mechanism 22 is used to press the second beam 52 against the second side positioning surface 204. On the premise that the first beam 51 and the second beam 52 are kept parallel with each other by means of the first positioning fixture 2 and the second positioning fixture 3, how to quickly position the first beam 51 and the second beam 52 to be parallel to each other is a problem that needs to be solved. When this problem is solved, the specific structure of the first positioning fixture 2 and the second positioning fixture 3 can be solved, that is, the positioning body 20 first provides a first side positioning surface 203 and a second side positioning surface 204, and then the first clamping mechanism 21 presses the first beam 51 on the first side positioning surface 203, and the second clamping mechanism 22 is used to press the second beam 52 on the second side positioning surface 204. The first side positioning surface 203 and the second side positioning surface 204 are the reference surfaces that need to be aligned, thereby achieving the first clamping mechanism 21 and the second clamping mechanism 22 to achieve the quick ring positioning of the first beam 51 and the second beam 52, thereby improving the installation and positioning efficiency while ensuring the high accuracy of the calibration result.
[0032] The first positioning fixture 2 and the second positioning fixture 3 also include: a third clamping mechanism 23. Two third clamping mechanisms 23 are installed on the positioning body 20. The third clamping mechanism 23 is used to clamp the calibration beam 4 on the return rope wheel 54. Since the positioning body 20 only supports the calibration beam 4, in order to position the calibration beam 4, the calibration beam 4 is prevented from moving randomly when being measured, and the calibration beam 4 is prevented from moving randomly and affecting the calibration result. The third clamping mechanism 23 is used to clamp the return rope wheel 54 between the first beam 51 and the second beam 52. Since the end face of the return rope wheel 54 is uneven, after the third clamping mechanism 23 presses the calibration beam 4 on the return rope wheel 54, there may be a situation where the distance between the end face of the return rope wheel 54 and the calibration beam 4 is different. This can detect whether the thickness between the two end faces of the return rope wheel 54 is uniform, so as to determine whether the return rope wheel 54 meets the quality requirements.
[0033] The first clamping mechanism 21, the second clamping mechanism 22 and the third clamping mechanism 23 all include: a fixed seat 210, a first rotating arm 211, a second rotating arm 212 and a clamping arm 213. The fixed seat 210 is installed on the positioning body 20. The fixed seat 210 is hinged to one end of the first rotating arm 211. The middle part of the first rotating arm 211 is hinged to one end of the second rotating arm 212. The other end of the second rotating arm 212 is hinged to one end of the clamping arm 213. The clamping arm 213 is guided by the fixed seat 210 and can move in a direction perpendicular to the first beam 51. The specific structural design of the first clamping mechanism 21, the second clamping mechanism 22 and the third clamping mechanism 23 realizes that the fixed seat 210 serves as the basis of the entire first clamping mechanism 21, the second clamping mechanism 22 or the third clamping mechanism 23. By manually rotating the first rotating arm 211, the middle part of the first rotating arm 211 can drive one end of the second rotating arm 212 to move, and the second rotating arm 212 rotates, and then the other end of the second rotating arm 212 drives the clamping arm 213 to move in a direction away from or close to the first beam 51, the second beam 52 or the calibration beam 4, thereby realizing the clamping or releasing function.
[0034] The clamping arm 213 includes: a first arm body and a second arm body, one end of the first arm body is hinged to the second rotating arm 212, the other end of the first arm body is threadedly connected to one end of the second arm body, and the other end of the second arm body is used to clamp the first beam 51, the second beam 52 or the calibration beam 4. The length of the second arm body extending from the first arm body can be adjusted as needed.
[0035] The positioning body 20 includes: a positioning upper arm 200, a first positioning block 201 and a second positioning block 202. The positioning upper arm 200 is pressed tightly above the first beam 51 and the second beam 52. The first positioning block 201 and the second positioning block 202 are installed below the positioning upper arm 200. There is a gap between the first positioning block 201 and the second positioning block 202. The first side surface of the first positioning block 201 and the first side surface of the second positioning block 202 form a first side positioning surface 203 on the same plane. The second side surface of the first positioning block 201 and the second side surface of the second positioning block 202 form a second side positioning surface 204 on the same plane. The first positioning block 201 and the second positioning block 202 are spaced apart so that there is a larger gap between the first side surface of the first positioning block 201 and the first side surface of the second positioning block 202, so that the smaller first side surface of the first positioning block 201 and the first side surface of the second positioning block 202 can form a larger first side positioning surface 203. Since the first side surface of the first positioning block 201 and the first side surface of the second positioning block 202 are smaller, it is easier and simpler to adjust the first side surface of the first positioning block 201 and the first side surface of the second positioning block 202 to form a first side positioning surface 203, thereby improving the adjustment efficiency. The first positioning block 201 and the second positioning block 202 are spaced apart so that there is a larger gap between the second side surface of the first positioning block 201 and the second side surface of the second positioning block 202, so that the smaller second side surface of the first positioning block 201 and the second side surface of the second positioning block 202 can form a larger second side positioning surface 204. Since the second side surface of the first positioning block 201 and the second side surface of the second positioning block 202 are smaller, it is easier and simpler to adjust the second side surface of the first positioning block 201 and the second side surface of the second positioning block 202 to form a second side positioning surface 204, thereby improving the adjustment efficiency.
