Description

Technical Field

[0001] The utility model relates to the technical field of anti-falling pulleys, in particular to an anti-falling tool for high-altitude operations. Background Art

[0002] In many application scenarios, cables carry high voltage or are used to transmit important control signals. If the cables fall off the cable pulley, they may fall and hit people below, posing a great safety hazard. Therefore, it is very important to prevent the cable pulley used for aerial work from falling off.

[0003] In Chinese patent CN209658761U, the utility model discloses a combined cable slide with a self-locking function, including an upper cable slide wheel group, a lower cable slide wheel group and a rotating shaft, wherein the upper cable slide wheel group and the lower cable slide wheel group are respectively rotatably connected to the outer surface of the rotating shaft, and both ends of the rotating shaft are fixedly connected to a fixed frame, and both ends of the fixed frame are rotatably connected to a movable rod through a first rotating rod, and the side of the movable rod is rotatably connected to a second rotating rod, and the movable rod is rotatably connected to a locking block through the second rotating rod, and a limited position hole is provided on the upper surface of the locking block. The utility model passes the cable between the upper cable slide wheel group and the lower cable slide wheel group, so that the cable can be guided to slide in all directions on the vertical plane, avoiding the disadvantage that only one cable slide wheel can not guide the cable in all directions in the traditional method, and the combined cable slide can slide multiple cables at the same time, which is highly practical and efficient.

[0004] The existing pulleys for aerial work have the problem that when two or more groups of cables are being slid at the same time, since the initial cables are released from the cable winding device, the cables have an upward curvature. When two or more groups of cables are being slid at the same time, the bowed cables are easy to jump on the pulleys and may jump from one pulley to another. As a result, the two cables will be entangled together, affecting normal transportation. In addition, since the cables have a certain curvature in their initial state, when they slide through the pulley and the pressing wheel, if the pressing wheel presses the cables too tightly and cannot adjust the tension, the friction between the cables and the cables will increase, causing certain damage to the cable surface.

[0005] In view of the above problems, a high-altitude operation anti-falling tool is proposed. Utility Model Content

[0018] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0019] 1. The utility model provides an anti-falling tool for high-altitude operations. When the cable is arched or jumped upward on the pulley due to various reasons, it will move upward against the pressing wheel. At this time, a gap will appear between the pressing wheel and the cable pulley at its bottom. The anti-jumping component is intercepted between the two groups of cable pulleys, which can effectively prevent the cable from jumping from one group of cable pulleys to the other group of cable pulleys, thereby preventing the two cables from being entangled on the pulleys, and the cable can rotate with the lower guide rotating block and the upper guide rotating block, thereby reducing the friction between the cable and its outer wall. At the same time, due to the special shape setting of the lower guide rotating block and the upper guide rotating block, the cable has a pushing and guiding effect to the middle position, thereby being able to push the cable back between the pressing wheel and the cable pulley for normal sliding.

[0020] 2. The utility model provides an anti-falling tool for high-altitude operations, in which a wire pressing wheel is arranged on the top of the cable pulley, and can have a downward pressure limiting effect on the cable on the cable pulley. When the cable on the cable pulley bends upward or jumps, the adjusting spring on the top of the wire pressing wheel can absorb and buffer this part of the kinetic energy. The wire pressing wheel can adaptively adjust the pressure according to the movement state of the cable. The adjusting spring will make the wire pressing wheel press down with appropriate elastic force, stabilize the cable on the cable pulley, reduce its vertical displacement, and ensure that the cable runs in a relatively stable position. Moreover, since the wire pressing wheel can be appropriately adjusted upward, the pressure on the cable below will not be too large, thereby facilitating the reduction of damage to the cable caused by excessive pressure.

[0032] The top of the adjusting spring 505 is fixedly connected to the top support frame 7, and a fixing component 8 is installed on the top of the top support frame 7, the fixing component 8 includes a fixing hook 801, and the connection method between the fixing hook 801 and the top support frame 7 is a fixed connection, and side anti-detachment components 6 are symmetrically arranged at both ends of the bottom support frame 1, and the side anti-detachment components 6 include a fourth rotating shaft 601, and the connection method between the fourth rotating shaft 601 and the bottom support frame 1 is a fixed connection.

[0033] The bottom of the lower guide rotating block 404 is slidably connected with the first ball 403, and the outside of the first ball 403 is rotatably connected with the bottom fixed block 402, and the connection between the bottom fixed block 402 and the second rotating shaft 401 is a fixed connection.

[0034] When the cable bends upward or jumps on the pulley due to various reasons, it will move upward against the pressing wheel 504. At this time, a gap will appear between the pressing wheel 504 and the cable pulley 3 at its bottom. If the cable has a tendency to move toward another cable pulley 3 at this time, it will first contact the upper guide turn block 405 and the lower guide turn block 404. The cable can rotate with the lower guide turn block 404 and the upper guide turn block 405, thereby reducing the friction between the cable and its outer wall.

[0036] The pressing wheel 504 is arranged on the top of the cable pulley 3, and can have a downward pressure limit effect on the cable on the cable pulley 3. When the cable on the cable pulley 3 bends upward or jumps, the adjusting spring 505 on the top of the pressing wheel 504 can absorb and buffer this part of the kinetic energy. The pressing wheel 504 can adaptively adjust the pressure according to the movement state of the cable. The adjusting spring 505 will make the pressing wheel 504 press down with appropriate elastic force, stabilize the cable on the cable pulley 3, reduce its vertical displacement, and ensure that the cable runs in a relatively stable position. Moreover, since the pressing wheel 504 can be appropriately adjusted upward, the pressure on the cable below will not be too large, which makes it easier to reduce the damage to the cable caused by excessive pressure.

[0037] The top of the fourth rotating shaft 601 is rotatably connected to a receiving block 602, and the top of the receiving block 602 is integrally connected to a side guide block 603, and the inner wall of the side guide block 603 is rotatably connected to a fourth ball 604, the top of the side guide block 603 is integrally connected to a side railing 605, and the top of the side railing 605 is threadedly connected to a fixing bolt 606, the fourth ball 604 is arranged at equal intervals about the inner wall of the side guide block 603, and the side guide block 603 is in an arc shape, the side railing 605 forms a threaded detachable structure with the top support frame 7 through the fixing bolt 606, and the connection method between the fixing bolt 606 and the top support frame 7 is a threaded connection.

[0038] Before using this device, turn and unscrew the fixing bolt 606, then the side railing 605 together with the side guide block 603 can be turned open, and the wire pressing wheel 504 can be pushed upward, so that the cable can be clamped between the wire pressing wheel 504 and the cable pulley 3 from the side. When the wire pressing wheel 504 rises and the cable jumps toward the side guide block 603, the arc-shaped side guide block 603 can effectively push the cable back to its original position again, and the inner wall of the side guide block 603 is provided with a fourth ball 604, which can convert the sliding friction between it and the cable into rolling friction, thereby reducing the wear on the cable.
