DETAILED DESCRIPTION

Here, the schematic implementation mode of the utility model and its description are used to explain the utility model, but are not used as a limitation of the utility model.

[0019] Reference Figure 1 , Figure 2 and Figure 3 A rope-locking device for preventing ropes from falling off comprises a transverse beam 1, a vertical cylinder 11 is fixed at the bottom of the transverse beam 1, a double-axis rod 12 is fixed on one side of the vertical cylinder 11, a rope-supporting wheel 2 is rotatably connected to the side wall of the vertical cylinder 11, and a steel wire rope 21 passes over the rope-supporting wheel 2. A hanging seat 3 is arranged on the steel wire rope 21, and a rope-holding device 31 is arranged at the top of the hanging seat 3. The rope-holding device 31 holds the steel wire rope 21, and the rope-holding device 31 can move together with the steel wire rope 21, thereby driving the hanging seat 3 to move.

[0020] The first connecting shaft 4 and the second connecting shaft 5 are fixed on the double-axis rod 12. The first connecting shaft 4 and the second connecting shaft 5 are located on the same side of the double-axis rod 12. The first connecting shaft 4 and the second connecting shaft 5 are at the same height. The second connecting shaft 5 is located on the side of the first connecting shaft 4 close to the rope support wheel 2.

[0021] The first connecting shaft 4 is sleeved with a first sleeve 41, which can rotate along the axis of the first connecting shaft 4. The second connecting shaft 5 is sleeved with a second sleeve 51, which can rotate along the axis of the second connecting shaft 5. Both the first sleeve 41 and the second sleeve 51 cannot move along the axis of the first connecting shaft 4.

[0022] The first connecting shaft 4 and the second connecting shaft 5 are both stepped shafts, one end of the first sleeve 41 contacts the shoulder of the first connecting shaft 4, and one end of the second sleeve 51 contacts the shoulder of the second connecting shaft 5. The end of the first sleeve 41 away from the dual-axis rod 12 is provided with a first blocking member 42 to prevent the first sleeve 41 from being separated from the first connecting shaft 4, and the end of the second sleeve 51 away from the dual-axis rod 12 is provided with a second blocking member 52 to prevent the second sleeve 51 from being separated from the second connecting shaft 4.

[0023] The first blocking member 42 includes a first anti-slip plate 421, a first bolt 422 and an abutting sleeve 423. The first anti-slip plate 421 is located at one end of the first sleeve 41 away from the dual-axis rod 12. The first bolt 422 passes through the abutting sleeve 423 and the first anti-slip plate 421 and is threadedly connected to the first connecting shaft 4. The second blocking member 52 includes a second anti-slip plate 521 and a second bolt 522. The second anti-slip plate 521 is located at one end of the second sleeve 51 away from the dual-axis rod 12. The second bolt 522 passes through the second anti-slip plate 521 and is threadedly connected to the second connecting shaft 5.

[0024] Reference Figure 3 A connecting rod 61 is fixed to the side of the first sector plate 6 away from the double-axis rod 12. The connecting rod 61 is located directly above the first connecting shaft 4. The plane formed by the axis of the first connecting shaft 4 and the axis of the connecting rod 61 is a vertical plane.

[0025] A rope retaining plate 8 is fixed to the bottom of the first sleeve 41, and a through slot 81 is provided on the rope retaining plate 8. The rope retaining plate 8 is in an inverted U shape through the through slot 81, and the width of the through slot 81 is larger than the diameter of the steel wire rope 21. In a normal state (the rope retaining plate 8 is only subjected to gravity), the rope retaining plate 8 is in a vertical state, and the rope retaining plate 8 is located below the first sleeve 41. The steel wire rope 21 passes through the through slot 81, and the steel wire rope 21 contacts both side walls of the through slot 81 in the vertical direction.

[0026] A first sector plate 6 is fixed to the first sleeve 41, and a second sector plate 7 is fixed to the second sleeve 51. The first sector plate 6 is located directly above the first sleeve 41, and the second sector plate 7 is located directly above the second sleeve 51 and offset clockwise by a certain angle. An L-shaped unlocking rod 9 is fixed below the second sleeve 51, and the unlocking rod 9 is in a naturally drooping standby state under the action of gravity.

[0027] Reference Figure 4 and Figure 5 The first sector plate 6 and the second sector plate 7 form a double-leaf lock structure. By changing the setting angles of the two first sector plates 6 and the second sector plates 7, different interlocking and unlocking functions can be achieved. In order to ensure the stability of the double-leaf lock when interlocked, the size of the double-leaf lock must comply with the Pythagorean theorem in design. Specifically, the first sector plate 6 and the second sector plate 7 are located in the same motion plane, and the square of the radius of the first sector plate 6 and the square of the radius of the second sector plate 7 are equal to the square of the distance between the axes of the first connecting shaft 4 and the second connecting shaft 5.

[0028] A right angle △ABC is established on a plane, and the axes of the two sector plates are located at points B and C respectively. When the second sector plate 7 is placed to cover line segment AB, the first sector plate 6 rotates counterclockwise to the edge of line segment AC and comes into contact with the second sector plate 7. The first sector plate 6 will not be able to continue to rotate counterclockwise. According to the Pythagorean theorem, it can be judged that the direction of the pressure of the first sector plate 6 on the second sector plate 7 will pass through the axis of the second sector plate 7. Therefore, this pressure cannot cause the first sector plate 6 to rotate. Therefore, the structure in which the first sector plate 6 is locked by the second sector plate 7 is stable and reliable.

[0029] Reference Figure 6 When the wire rope 21 and the rope supporting wheel 2 need to be inspected and repaired, the rope blocking plate 8 is manually operated to flip forward 90 degrees clockwise, and the unlocking rod 9 is flipped 270 degrees counterclockwise, and the unlocking rod 9 is pressed on the connecting rod 61 and the abutment sleeve 423. At this time, the anti-rope-slipping rope locking device can form a stable structure under the action of its own weight, and will not interfere with the replacement of the wire rope 21, the replacement of the rope supporting wheel 2, etc.

[0030] The implementation principle of the rope-locking device for preventing rope from falling off of the utility model is as follows:

[0031] When the steel wire 21 moves normally, the rope stopper 8 and the unlocking lever 9 are in a naturally drooping standby state under the action of gravity. When the steel wire 21 drives the rope gripper 31 on the hanging seat 3 to pass under the unlocking lever 9 and the rope stopper 8, the unlocking lever 9 is first triggered by the rope gripper 31 and lifted up forward and upward, and then the rope stopper 8 is triggered by the rope gripper 31 and also lifted up forward and upward, and the hanging seat 3 passes smoothly. After the hanging seat 3 passes, the rope stopper 8 and the unlocking lever 9 return to the standby state under the action of gravity.

[0032] When the moving wire rope 21 is laterally derailed, the wire rope 21 has a tendency to continue to move obliquely forward, which can be decomposed into two sub-movement trends, namely forward movement and lateral movement. The lateral movement will press the wire rope 21 against the rope baffle plate 8, while the forward movement will cause the wire rope 21 to drive the rope baffle plate 8 to flip up forward and upward. At this time, the first fan-shaped plate 6 above the rope baffle plate 8 is pressed on the second fan-shaped plate 7, and the rope baffle plate 8 cannot be further flipped up forward and upward, that is, the rope baffle plate 8 is locked, so that the rope baffle plate 8 can continuously limit the lateral movement of the wire rope 21, thereby preventing the wire rope 21 from being laterally derailed.

[0033] When it is necessary to inspect and repair the wire rope 21 and the rope supporting wheel 2, the rope stop plate 8 is manually flipped forward 90 degrees, and the unlocking rod 9 is flipped backward 270 degrees, and the unlocking rod 9 is pressed onto the rope stop plate 8. At this time, the anti-rope-slipping rope locking device can form a stable structure under the action of its own weight. The rope stop plate 8 and the unlocking rod 9 are separated from the vicinity of the wire rope 21 together, and will not interfere with the replacement of the wire rope 21, the replacement of the rope supporting wheel 2, etc., thereby achieving the purpose of not affecting other maintenance work.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
