[0022] As Figure 1 shown, an embodiment of the present invention provides a guiding system for lifting a system, including: a lifting unit 1, a guiding control unit 2, a structural frame 3, a guiding electromagnet 4, and a track 5; The track 5 is installed on the structural frame 3; A space for placing the lifting unit 1 is formed by the structural frame 3 and the track 5; The guiding electromagnet 4 is installed on the lifting unit 1; The guiding control unit 2 is connected to the guiding electromagnet 4 and is used to control the current of the guiding electromagnet 4.

[0023] In the actual operation process, this guiding system is composed of a lifting unit, a guiding control unit, a structural frame, a guiding electromagnet, and a track. Among them, the structural frame is a steel structural frame, and the steel structural frame is installed on the shaft wall 6. The lifting unit is a lifting container. By installing the track on the steel structural frame, placing the lifting unit in the space formed by the steel structural frame and the track, then installing the guiding electromagnet on the lifting unit, generating electromagnetic suction with the track, and radio connecting the guiding control unit with the guiding electromagnet to control the current of the guiding electromagnet, the problem of the lifting container shaking caused by the fluctuation of the wire rope in the ultra-deep well can be solved, the stability and reliability of the lifting system can be improved, and the safety hazard can be eliminated.

[0024] Preferably, the guiding electromagnet 4 includes a gap sensor 40.

[0025] In the actual operation process, the guiding electromagnet includes a gap sensor, and also includes an inner pole plate, an outer pole plate, an excitation coil, an anti-collision skid, and a clamp. There are 4 groups of guiding electromagnets, namely the first guiding electromagnet 41, the second guiding electromagnet 42, the third guiding electromagnet 43, and the fourth guiding electromagnet 44. Each group contains two guiding electromagnets, denoted as the first guiding electromagnet 1 and the first guiding electromagnet 2, the second guiding electromagnet 1 and the second guiding electromagnet 2, the third guiding electromagnet 1 and the third guiding electromagnet 2, the fourth guiding electromagnet 1 and the fourth guiding electromagnet 2. Among them, as Figure 2 shown, the guiding electromagnets are symmetrically arranged on both side walls of the lifting unit. The first guiding electromagnet and the third guiding electromagnet are symmetrically distributed with respect to the second direction 12 of the lifting unit, the second guiding electromagnet and the fourth guiding electromagnet are symmetrically distributed with respect to the second direction 12 of the lifting unit, the first guiding electromagnet and the second guiding electromagnet are symmetrically distributed with respect to the third direction 13 of the lifting unit, the third guiding electromagnet and the fourth guiding electromagnet are symmetrically distributed with respect to the third direction 13 of the lifting unit. Each group of guiding electromagnets (guiding electromagnet 1 and guiding electromagnet 2) is perpendicularly and symmetrically arranged with respect to the first direction 11 of the lifting unit. And the guiding electromagnet 1 in each group of guiding electromagnets is located above the lifting unit, and the guiding electromagnet 2 is located below the lifting unit. The three directions of the lifting unit in this embodiment can be understood as placing the lifting unit in a three-dimensional coordinate (X, Y, Z). The first direction of the lifting unit is on the XY plane; the second direction of the lifting unit is on the XZ plane; the third direction of the lifting unit is on the YZ plane.

[0026] Preferably, the gap sensor includes a first gap detection unit, a second gap detection unit, and a third gap detection unit.

[0027] In the actual operation process, the gap sensor includes a first gap detection unit, a second gap detection unit, and a third gap detection unit. The three-way gap detection unit is used to detect the guiding gap value. The guiding control unit judges whether the gap is too large or too small according to the guiding gap value, and correspondingly adjusts the current magnitude of the guiding electromagnet. First, it is very difficult to make the track seamless. When passing through the rail gap, at least one of the gap detection units will be affected and cannot be used. It is necessary to take the signals of the other two paths for control operation. Secondly, the three-way gap detection unit has a redundant function.

[0028] Preferably, the track 5 is specifically a π-shaped track; the π-shaped track specifically includes: a first π-shaped track 51, a second π-shaped track 52, a third π-shaped track 53, and a fourth π-shaped track 54; The first π-shaped track 51 is the acting object of the first guiding electromagnet, the second π-shaped track 52 is the acting object of the second guiding electromagnet, the third π-shaped track 53 is the acting object of the third guiding electromagnet, and the fourth π-shaped track 54 is the acting object of the fourth guiding electromagnet.

[0029] In the actual application process, the adopted track is a π-shaped track. As Figure 3 shown, the π-shaped track is distributed in three directions. 55 is the first direction of the π-shaped track, 56 is the second direction of the π-shaped track, and 57 is the third direction of the π-shaped track. Its first direction 55 is installed on the steel structure frame. The track surface is the gap detection surface of the gap sensor, and the detection surface is the surface where the first direction 55 is located. However, below the track, that is, the lower surface of the track forming an angle with the second direction 56 and the third direction 57; the tracks in the second direction 56 and the third direction 57 are magnetic pole surfaces, generating suction force with the magnetic pole surfaces of the guiding electromagnets to ensure the lateral and longitudinal guiding functions of the lifting unit. Among them, the track along the first direction 55 is parallel to the deep well wall and the magnetic pole surface of the guiding electromagnet. The track in the second direction 56 is the outer side surface of the π-shaped rail, and the included angle with the first direction 55 is denoted as α. The track in the third direction 57 is the inner side surface of the π-shaped rail, and the included angle with the first direction 55 is denoted as β; among them, there are specifically 4 π-shaped tracks, which are respectively installed on the steel structure frame, namely the first π-shaped track, the second π-shaped track, the third π-shaped track, and the fourth π-shaped track. The first π-shaped track is the object of action of the first guiding electromagnet 1 and the first guiding electromagnet 2. The second π-shaped track is the object of action of the second guiding electromagnet 1 and the second guiding electromagnet 2. The third π-shaped track is the object of action of the third guiding electromagnet 1 and the third guiding electromagnet 2. The fourth π-shaped track is the object of action of the fourth guiding electromagnet 1 and the fourth guiding electromagnet 2.

[0030] Preferably, the guiding control unit controls the guiding gap between the guiding electromagnet and the track; Among them, the guiding gaps are respectively the first guiding gap, the second guiding gap, the third guiding gap, and the fourth guiding gap.

[0031] In the actual application process, there are specifically 4 groups of guiding control units. Each group consists of two guiding control units, namely the first guiding control unit 1 and the first guiding control unit 2, the second guiding control unit 1 and the second guiding control unit 2, the third guiding control unit 1 and the third guiding control unit 2, and the fourth guiding control unit 1 and the fourth guiding control unit 2; the 4 groups of guiding control units respectively control 4 groups of guiding electromagnets. Among them, each group of guiding electromagnets and each π-shaped track will form two guiding gaps, denoted as the first guiding gap 1 (S 1,1 ), and the first guiding gap 2 (S 1,2 ), the second guiding gap 1 (S 2,1 ), and the second guiding gap 2 (S 2,2 ); the third guiding gap 1 (S 3,1 ), and the third guiding gap 2 (S 3,2 ); the fourth guiding gap 1 (S 4,1 ), and the fourth guiding gap 2 (S4,2 ); And the four groups of guiding control units respectively control the above-mentioned guiding gaps; In this embodiment, by controlling the guiding gap between the guiding electromagnet and the π-shaped track, the functions of lateral active guiding and longitudinal passive guiding of the lifting unit are realized.

[0032] As Figure 4 shown, an embodiment of the present invention provides a guiding method for a lifting system, including the following steps: S1. Detect the guiding gap value between the guiding electromagnet and the π-shaped track through a gap sensor; In step S1, each set gap sensor is used to detect the guiding gap value between the corresponding guiding electromagnet and the π-shaped track which is the acting object of the guiding electromagnet, and send the guiding gap value to the corresponding guiding control unit.

[0033] S2. The guiding control unit receives the guiding gap value transmitted by the gap sensor and calculates the first comprehensive gap; In step S2, each guiding control unit receives the guiding gap values transmitted by the first, second, and third gap detection units of the corresponding gap sensor, and calculates the comprehensive gap of the guiding control unit according to the guiding gap value , for example, if the three-way guiding gap values are all normal, the average of the two smaller ones can be taken, and if one is faulty, the smaller gap value among the remaining two can be taken.

[0034] S3. The guiding control unit receives the second comprehensive gap value transmitted by the adjacent guiding control unit; In step S3, each guiding control unit also simultaneously receives the comprehensive gap value transmitted by the adjacent guiding control unit , which is convenient for subsequent calculation; There are three adjacent guiding control units here, and correspondingly there are also 3 comprehensive gap values; Such as the adjacent comprehensive gap values of the first guiding electromagnet first guiding control unit comprehensive gap are respectively , , , it is necessary to ensure that the deviation of the gap values in the front and back, left and right, and up and down directions is within the preset range to prevent the lifting unit from tilting.

[0035] S4. Adjust the current of the guiding electromagnet according to the guiding gap deviation between the first comprehensive gap and the second comprehensive gap value.

[0036] In step S4, the guiding control unit performs current adjustment according to the guiding gap deviation between the comprehensive gap obtained in step S2 and the comprehensive gap value of the adjacent guiding control unit obtained in step S3, where upper and lower limit values are assigned to the above-mentioned guiding gap deviation , and all guiding clearance deviations are within the range.

[0037] In this embodiment, an equalization control strategy is adopted for the guiding clearances of 8 guiding electromagnets, that is, the guiding clearances of each guiding electromagnet should be equal. When the clearance deviation exceeds , the guiding control unit calculates based on the guiding clearance value and controls the current of the corresponding guiding electromagnet to achieve clearance equalization, avoiding tilting of the lifting container and causing safety accidents.

[0038] Its clearance and current adjustment simultaneously satisfy the following equalization control strategy: If and , then increase the current of the th guiding electromagnet . Conversely, decrease the current of the th guiding electromagnet ; Taking the clearance values , , , in step S3 as an example, if and > , then increase the current of the first guiding electromagnet M 1,1 . Conversely, decrease the current of the first guiding electromagnet M 1,1 .

[0039] If and , then increase the current of the th guiding electromagnet . Conversely, decrease the current of the th guiding electromagnet ; Taking the clearance values , , , in step S3 as an example, if and > , then increase the current of the first guiding electromagnet M 1,1 .

[0040] If and , then increase the current of the th guiding electromagnet . Conversely, decrease the current of the th guiding electromagnet ; Taking the clearance values , , , For example, if and > , then increase the current of the first guiding electromagnet M 1,1 , and vice versa, then decrease the current of the first guiding electromagnet M 1,1 .

[0041] Among them, i represents the number of the guiding electromagnet, which are the first guiding electromagnet, the second guiding electromagnet, the third guiding electromagnet, and the fourth guiding electromagnet respectively. , if , then is , and vice versa, then it is ; if , then is , and vice versa, then it is ; j represents the number of the guiding control unit, which are the first guiding control unit and the second guiding control unit respectively. , if , then is , and vice versa, then it is .
