The middle part of the bracket 2 is provided with a plate card 10 fixedly connected to the traction rope 4, and the plate card 10 is composed of two steel plates, and the two steel plates clamp the traction rope 4 and are fastened with bolts. A top rod 11 is provided at the top of the plate card 10, and a top seat is provided at the top of the top rod 11 12, a hinge support is respectively provided on both sides of the bracket 2 corresponding to the rope clamping mechanism 9, a crank arm 7 is hinged on the hinge support, and the outward end of the crank arm 7 is movably connected to the corresponding rope clamping mechanism 9, the crank arms 7 on both sides are connected to a cross bar 5 through a connecting rod 6, the middle part of the cross bar 5 matches the top seat 12, a tension spring 8 is connected to the crank arm 7, one end of the tension spring 8 is connected to the bracket 2, and the tension spring 8 makes the outer end of the crank arm 7 have a tendency to rotate upward; a limiting mechanism 3 is provided at the lower end of the bracket 2 corresponding to the top rod 11, and the limiting mechanism 3 is used to limit the top seat 12 from falling downward.
[0019] Furthermore, the rope clamping mechanism 9 includes a wedge box 91, the upper and lower ends of the wedge box 91 are provided with rope holes, the stabilizing rope 1 passes through the rope holes, a guide slope 92 is provided on each side of the wedge box 91, each guide slope 92 is equipped with a wedge block 93, the stabilizing rope 1 passes through the gap between the two wedge blocks 93, the outer end of the crank arm 7 is slidably connected to the bottom of the two wedge blocks 93, and when the outer end of the crank arm 7 rotates upward, it drives the two wedge blocks 93 to move upward to clamp the stabilizing rope 1.
[0020] Furthermore, the top rod 11 and the top seat 12 are hollow structures that penetrate from top to bottom, and the traction rope 4 passes through the top seat 12 and the top rod 11 and is fixedly connected to the board 10 .
[0021] Furthermore, the limiting mechanism 3 includes two limiting plates 31, the opposite ends of the two limiting plates 31 are butt-jointed and a limiting hole 34 is provided at the joint, the size of the limiting hole 34 is larger than the top rod 11 and smaller than the top seat 12, and the outward ends of the two limiting plates 31 are each connected to a rotating shaft 33, both ends of the rotating shaft 33 are rotatably connected to the bracket 2, and the two rotating shafts 33 are connected by a connecting rod mechanism 32, and the connecting rod mechanism 32 is provided with a pull rope, which drives the connecting rod mechanism 32 by stretching and then drives the two rotating shafts 33 to rotate, so that the two limiting plates 31 rotate to open the limiting holes 34.
[0022] Furthermore, the connecting rod mechanism 32 includes a connecting rod A and a connecting rod B respectively connected to two rotating shafts 33. The connecting rod A and the connecting rod B are rotatably connected via a connecting rod C. A crank arm is provided at one end of the connecting rod B. The connecting rod B is driven to rotate around the rotating shaft by rotating the crank arm, and the connecting rod A rotates around another rotating shaft at the same time. The rotation directions of the connecting rod A and the connecting rod B are opposite, thereby realizing the synchronous opening of the two limit plates upward or the closing of the limit holes 34 downward.
[0023] Furthermore, the stretch bottom is provided with a pull ring.
[0024] Furthermore, a positioning hole is provided at the position where the bottom surface of the cross bar 5 matches the top seat 12 .
[0025] In normal operation of this embodiment, the traction rope 4 drives the entire support 2 to move upward through the plate card 10, the top rod 11 and the top seat 12, and the two ends of the support 2 slide relative to the stabilizing rope 1; when moving into the well, the winch releases the rope, and the support 2 and the bucket 13 move downward along the stabilizing rope 1 at both ends under the action of their own weight. During the movement, the top seat 12 always presses against the cross bar 5; when the support 2 moves to the hanging tray at the bottom of the well and the bucket 13 needs to pass through the hanging tray, the support 2 stays above the hanging tray, and the operator in the bucket 13 pulls the pull ring to drive the connecting rod mechanism 32 through stretching, so that the two The limit plate 31 rotates upward to open the limit hole 34, and the top seat 12 can pass through the limit hole 34 and continue to move downward. Since the height of the hanging plate from the bottom of the well is generally low, the anti-fall function can be ignored at this time. When the bucket 13 needs to pass through the hanging plate again, it is only necessary to pull the pull ring again to rotate the two limit plates 31 upward to open them, so that the top seat 12 can pass through the limit hole 34 upward. At this time, release the pull ring again, and the two limit plates 31 will reset to the closed state under the action of their own weight. The limit mechanism 3 can play a limiting role again, and the anti-fall function can be restored again.
[0026] In this embodiment, when the traction rope 4 breaks, Figure 2 , Figure 4 As shown, the bucket 13 with the broken traction rope 4 drives the plate card 10 and the top rod 11 to fall, and the top seat 12 also falls with the top rod 11. Due to the existence of the limiting plate 31, the top seat 12 stays at the limiting plate 31. At this time, the cross bar 5 loses the upward thrust of the top seat 12, and at the same time, the crank arms 7 at both ends of the cross bar 5 are subjected to the upward pulling force of the tension spring 8; therefore, the cross bar 5 falls downward, and at the same time, the outer ends of the crank arms 7 at both ends rotate upward, and the two crank arms 7 simultaneously push the wedge blocks 93 on both sides to move upward. Under the action of the guiding inclined surface 92, the two wedge blocks 93 move upward while also squeezing toward the middle stabilizing rope 1. Since the wedge box 91 is fixedly connected to the bracket 2, the bracket 2 will stay on the stabilizing rope 1 and will not continue to fall. At this time, the bucket 13 cannot fall because the top seat 12 is stuck by the limiting mechanism 3, thus realizing the anti-falling function.
