The second positioning part is used for positioning the jack 7, so that the jack 7 is perpendicular to the upper side of the base 5. The vertical line between the axis of the through hole 4 and the axis of the winding drum 2 refers to a line which is connected with the axis of the through hole 4 at one end and connected with the axis of the winding drum 2 at the other end and perpendicular to the axis of the through hole 4 and the axis of the winding drum 2.
[0047] The first positioning part is arranged to position the through hole 4, so that the vertical line between the axis of the through hole 4 and the axis of the winding drum 2 is parallel to the upper side of the base 5, and it is easier to make the vertical line between the axis of the through hole 4 and the axis of the winding drum 2 parallel to the upper side of the base 5, that is, it is easier to make the vertical line between the axis of the connecting part and the axis of the winding drum 2 parallel to the upper side of the base 5. The second positioning part is arranged to position the jack 7, so that the jack 7 is perpendicular to the upper side of the base 5, and it is easier to make the jack 7 perpendicular to the upper side of the base 5.
[0048] In the embodiment, the connecting part further comprises a round rod 12, which is fixedly connected to the other end surface of the screw rod 10, and the round rod 12 is coaxially arranged with the screw rod 10.
[0049] The first positioning part comprises a vertical plate 13, a horizontal rod 14, a bearing plate 15 and a spiral spring 16.

The bearing plate 15 is fixedly arranged at one end of the horizontal rod 14 close to the middle of the base 5 and is parallel to the vertical plate 13. The spiral spring 16 is located between the vertical plate 13 and the bearing plate 15, and one end of the spiral spring 16 is fixedly connected to the vertical plate 13 and the other end is fixedly connected to the horizontal rod 14.
[0050] Since the round rod 12 and the screw rod 10 are coaxially arranged, the overall structure of the connecting part is still coaxially arranged with the through hole 4.
[0051] When the winch is moved to be supported on the base 5, the winch is located on the side of the bearing plate 15 away from the vertical plate 13, the axis of the winding drum 2 is parallel to the vertical plate 13, and the round rod 12 is located on the side of the bearing plate 15 away from the vertical plate 13.
[0052] When the winch braking torque detection device is used to detect the braking torque of the winch, after the connecting part is fixedly connected to the wing plate 3, the winding drum 2 is rotated, the wing plate 3 is rotated with the winding drum 2, the wing plate 3 drives the connecting part to move on a circular path, the round rod 12 is rotated to the side of the winding drum 2 close to the vertical plate 13, and the circumferential surface of the round rod 12 abuts against the bearing plate 15.
[0053] Then reciprocating rotation of the winding drum 2, so that the wing plate 3 reciprocating rotation, the wing plate 3 drive connection part in a circular path up and down reciprocating movement, can make the circular rod 12 in a circular path up and down reciprocating movement. Because the circular rod 12 of the circumference of the bearing plate 15, in the circular rod 12 in a circular path up and down reciprocating movement process, the bearing plate 15 and the cross bar 14 can be reciprocating under the action of the push of the circular rod 12 and the push of the spiral spring 16 close to and away from the middle of the base 5, the cross bar 14 of the bearing plate 15 can reciprocating close to and away from the side of the vertical plate 13. In the process of reciprocating movement of the cross bar 14, the length scale line 17 is convenient for reference to obtain the distance between the cross bar 14 of the bearing plate 15 and the side of the vertical plate 13 away from the bearing plate 15, when the distance between the cross bar 14 of the bearing plate 15 and the side of the vertical plate 13 away from the bearing plate 15 reaches the maximum, stop rotating the winding drum 2, at this time the vertical line between the axis of the through hole 4 and the axis of the winding drum 2 can be parallel to the upper side of the base 5. With this structure, the first positioning part can position the through hole 4, so that the vertical line between the axis of the through hole 4 and the axis of the winding drum 2 is parallel to the upper side of the base 5.

Since the sides of the two stop blocks 19 away from the vertical plate 13 are parallel to the vertical plate 13 and located on the same plane, and since the axis of the winding drum 2 is parallel to the long edge of the base frame 1, at this time, the axis of the winding drum 2 can be parallel to the vertical plate 13, which is more convenient.
[0057] In the embodiment, the cross section of the horizontal rod 14 is non-circular. In the embodiment, the cross section of the horizontal rod 14 is rectangular. Since the horizontal rod 14 is slidingly fitted in the through hole, the cross section of the horizontal rod 14 is non-circular, so that the horizontal rod 14 can only slide in the through hole, but cannot rotate in the through hole.

[0059] The connecting part further comprises a bolt 20, which is screwed in the screw hole, and the screw-in end of the bolt 20 is used to abut against the horizontal rod 14.
[0060] When the screw-in end of the bolt 20 does not abut against the horizontal rod 14, the horizontal rod 14 can move in the through hole; the bolt 20 is rotated in the screw hole, so that the bolt 20 moves towards the direction where the horizontal rod 14 is located, and the screw-in end of the bolt 20 abuts against and tightly abuts against the horizontal rod 14, at this time, the horizontal rod 14 can be fixed on the vertical plate 13, and the horizontal rod 14 cannot continue to move in the through hole.
[0061] After the vertical line between the axis of the through hole 4 and the axis of the winding drum 2 is parallel to the upper side of the base 5, the winch is in a braking state, then the horizontal rod 14 and the abutting plate 15 are moved away from the circular rod 12, so that the abutting plate 15 is in a state of being separated from the circular rod 12, then the horizontal rod 14 is fixed on the vertical plate 13 by the bolt 20, so that the abutting plate 15 remains in a state of being separated from the circular rod 12.
[0062] During the process that the jack 7 pushes and presses the connecting part upwards, the abutting plate 15 does not abut against the circular rod 12, and the abutting plate 15 does not cause friction force to the circular rod 12, so that the detected braking torque can more accurately reflect the actual braking torque of the winch.
[0063] In the embodiment, the length scale line 17 is arranged outside the range of the side of the horizontal rod 14 facing the screw hole. When the bolt 20 is rotated in the screw hole, the bolt 20 does not rub against the length scale line 17, so that the possibility of the length scale line 17 being worn can be reduced.
