As shown in fig. 1 and 2, the correcting apparatus of the present invention further includes a locking rod 20 as a locking member, the locking rod 20 having an unlocking position and a locking position, and locking holes 21 communicating with each other are provided on the wall of the installation cavity and the horizontal section of the lower adjusting rod 10, when the lower adjusting rod 10 is located at the leftmost end, the locking rod 20 penetrates into the locking hole 21, the lower adjusting member can be locked in the installation box 5, the lower adjusting member cannot move, the locking rod 20 is located at the locking position, and the locking rod 20 is located at the unlocking position after being pulled out.
The steel cable 1 between the friction power wheel 3 and the upper rotating wheel 9 extends along the vertical direction, the steel cable 1 between the auxiliary wheel 4 and the lower rotating wheel 12 extends to the lower right and bypasses the auxiliary wheel 4, and when the locking rod 20 is in the unlocking position and the steel cable 1 is tensioned, the steel cable 1 can push the lower rotating wheel 12 to translate to the right along the lower translation groove 14.
When the lengths of the four steel cables 1 of the mine hoisting equipment are different and the tensions of the steel cables 1 are different, the length of the steel cables 1 is adjusted by using the correcting equipment of the invention as follows:
the method comprises the following steps: the friction power wheel 3 is controlled to rotate anticlockwise to enable the lifting block 6 to fall into the well bottom or be clamped at any height in the well, the steel cable 1 between the friction power wheel 3 and the lifting block 6 is loosened without tension, and then the locking rod 20 is pulled out of the locking hole 21 to be in an unlocking position.
Step two: and then the friction power wheel 3 is controlled to rotate clockwise to lift the lifting block 6, the steel cable 1 between the friction power wheel 3 and the lifting block 6 is tensioned and has tension, the rightward acting force exerted on the lower rotating wheel 12 is greater than the leftward acting force exerted on the upper rotating wheel 9, the four lower rotating wheels 12 slide rightward along the lower translation groove 14, the second ratchet rack 19 drives the first ratchet rack 18 to move rightward, and the lower adjusting rod 10 fixed on the lower rotating wheel 12 pushes the linkage rod 16 to slide rightward in the linkage long groove so that the upper rotating wheel 9 compresses the pressure spring 15 rightward.
Because the lengths of the steel cables 1 passing around the four lower rotating wheels 12 are different, the sliding distances of the four lower rotating wheels 12 to the right are different (as shown in fig. 6), and the sliding distance of the lower rotating wheel 12 corresponding to the shortest steel cable 1 to the right is the largest, assuming that the sliding distances of the four lower rotating wheels 12 to the right are respectively L1 > L2 > L3 > L4, when the other three lower rotating wheels 12 stop moving, the lower rotating wheel 12 corresponding to the shortest steel cable 1 continues to slide to the right, and the lower adjusting rod 10 on the lower rotating wheel 12 pushes the linkage rod 16 to continue to move to the right. Because the first ratchet bar 18 and the second ratchet bar 19 are in one-way transmission, the upper rotating wheel 9 moves rightwards relative to the lower rotating wheel 12 and cannot be blocked, the linkage rod 16 can simultaneously drive the four upper rotating wheels 9 to continue to compress the pressure springs 15 rightwards until the lower rotating wheel 12 corresponding to the shortest steel cable 1 moves to the limit position, at the moment, the four pressure springs 15 are all compressed by L1, the four upper rotating wheels 9 all move rightwards by L1, and the distances between the linkage rod 16 and the lower adjusting rods 10 on the four lower rotating wheels 12 are respectively 0, L1-L2, L1-L3 and L1-L4.
Step three: and then the friction power wheel 3 is controlled to rotate anticlockwise, the lifting block 6 falls into the well bottom or is clamped at any height in the well, and the steel cable 1 between the friction power wheel 3 and the lifting block 6 is loosened without tension. Because the unidirectional transmission structure formed by the first ratchet bar 18 and the second ratchet bar 19 is arranged between the upper rotating wheel 9 and the lower rotating wheel 12, the upper rotating wheel 9 can drive the lower rotating wheel 12 to move leftwards through the matching between the first ratchet bar 18 and the second ratchet bar 19 under the action of the leftward thrust of the pressure spring 15.
In the second step, the distances of the four lower rotating wheels 12 sliding rightwards are different, so that the lower rotating wheel 12 with the smallest rightward sliding distance moves L4 first and is limited by the lower translation groove 14, the first reset is realized, the corresponding pressure spring 15 stops releasing after releasing the distance L4 under the constraint of the lower translation groove 14 and the first ratchet bar 18 and the second ratchet bar 19, the corresponding upper rotating wheel 9 resets L4 leftwards and then is static, and compared with the initial state, the distance of the corresponding upper rotating wheel 9 moving rightwards is L1-L4. By analogy, the lower rotating wheel 12 with the largest rightward sliding distance is finally reset, and the upper rotating wheels 9 corresponding to the four short-to-long steel cables 1 move rightward at different distances (as shown in fig. 7) compared with the initial state, wherein the specific distances are respectively 0, L1-L2, L1-L3 and L1-L4, so that the lengths of all the steel cables 1 outside the length correction equipment are kept consistent.
It should be noted that, in the second step, the distances between the linkage rod 16 and the lower adjustment rods 10 on the four lower rotation wheels 12 are respectively 0, L1-L2, L1-L3, and L1-L4, so that in the process that the compression spring 15 is released and the upper rotation wheel 9 moves leftward in the third step, the linkage rod 16 does not contact the four lower adjustment rods 10 at the same time, and along with the leftward movement of the linkage rod 16, the linkage rod 16 sequentially contacts the four lower adjustment rods 10, and in this process, the lower rotation wheel 12 is reset by means of one-way transmission matching between the first ratchet bar 18 and the second ratchet bar 19.
Step four: the locking rod 20 is inserted into the locking hole 21 again, thus completing the adjustment process.
in embodiment 1, the upper adjustment rod and the lower adjustment rod are both L-shaped rods having a horizontal section and a vertical section, and one end of the pressure spring is fixed to the horizontal section of the upper adjustment rod. In this embodiment, different from embodiment 1, the upper adjusting rod is a straight rod arranged obliquely, one end of the straight rod is fixed on the upper rotating shaft, the other end of the straight rod extends to the linkage rod, and the pressure spring is fixed on the upper rotating shaft.
in embodiment 1, the anti-tilt member is a nut threaded onto the extended end of the linkage rod, and the diameter of the nut is greater than the width of the linkage long hole. In this embodiment, unlike embodiment 1, the anti-tilting member is a stopper pin inserted into the extended end of the linkage rod, and the length of the stopper pin is greater than the width of the linkage long hole.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
