Detailed implementation manners
[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0036] Please refer to Figure 1-8 , the present invention provides a technical solution: a rope ladder that is anti-wear and easy to carry, as Figure 1 and Figure 2As shown, it includes a storage cylinder 1 and a locking mechanism 16. A handle 2 is fixed to the top of the storage cylinder 1, and a hook 3 is fixed to the rear side of the storage cylinder 1. A threaded rod 4 passes through the hook 3. The front end of the threaded rod 4 is rotatably connected to a blocking block 5. After hanging the hook 3 on the relevant equipment, the threaded rod 4 can be tightened, and the blocking block 5 finally presses tightly against the equipment, facilitating the installation and fixation of the device.
[0037] As Figure 1 shown, on both sides inside the storage cylinder 1, support plates 6 are symmetrically fixed. A winding rod 8 is rotatably connected between the two support plates 6. A motor 7 is fixed to the inner bottom of the storage cylinder 1, and the output end of the motor 7 is connected to the winding rod 8. The winding rod 8 can rotate under the action of the motor 7, facilitating the release or retraction of the rope ladder mechanism 9.
[0038] As Figure 1 、 Figure 2 、 Figure 3 and Figure 8 shown, a rope ladder mechanism 9 is wound around the outside of the winding rod 8. The rope ladder mechanism 9 passes through an opening 10. The opening 10 is opened at the bottom of the storage cylinder 1. The rope ladder mechanism 9 includes a suspension rope 901, ladder rods 902, bolts 904, and a first groove 907. The suspension rope 901 is wound around the outside of the winding rod 8, and the suspension rope 901 passes through the opening 10. Clamping sleeves 903 are fixed to both sides of the ladder rod 902. A metal ring 905 is inlaid in the suspension rope 901. The bolt 904 passes through the clamping sleeve 903 and the metal ring 905 and is threadedly connected to the ladder rod 902. A lead block 906 is fixed to the bottom of the suspension rope 901. Both the suspension rope 901 and the ladder rod 902 are made of wear-resistant materials. The first groove 907 is opened at the bottom of the bottommost ladder rod 902, and a camera 908 and a lighting lamp 909 are fixed to the top of the first groove 907. A transparent sheet 910 is fixed to the bottom of the first groove 907. After sleeving the ladder rod 902 outside the two suspension ropes 901 using the clamping sleeve 903, the ladder rod 902 can be fixed using the bolt 904. Each ladder rod 902 can be individually disassembled and replaced. During the process of releasing the suspension rope 901, the lead block 906 plays a role in pulling the suspension rope 901. The combination of the camera 908 and the lighting lamp 909 can be used to observe the distance between the bottommost ladder rod 902 and the ground. The suspension rope 901 and the ladder rod 902 are wear-resistant and have a long service life.
[0039] As Figure 1 、 Figure 4 and Figure 5As shown, the winding rod 8 penetrates through the two support plates 6. One end of the winding rod 8 is fixed with a turntable 11. A second groove 12 is formed on the outer side of the turntable 11. A rotating block 13 is rotatably connected in the second groove 12. There are six rotating blocks 13, and the six rotating blocks 13 are symmetrically distributed about the center on the turntable 11. The rotating blocks 13 are arranged in one-to-one correspondence with the blocking blocks 1604. When the motor 7 operates abnormally and causes the winding rod 8 and the turntable 11 to rotate at a high speed, the rotating blocks 13 open, and each rotating block 13 pushes the corresponding blocking block 1604 to move, and the rotating sleeve 1603 will rotate along with the rotation of the turntable 11.
[0040] As Figure 1 , Figure 4 and Figure 5 shown, the rotating block 13 is connected to the turntable 11 through a volute spring 14. A clamping groove 15 is formed on one side of the turntable 11, and the clamping grooves 15 are circumferentially and evenly distributed on the turntable 11. When the rotation speed of the turntable 11 is abnormal, the rotating block 13 rotates and opens, and the rotating block 13 plays a role in pushing the blocking block 1604. After the rotating sleeve 1603 rotates to the end, the bolt 1607 will automatically spring into the corresponding clamping groove 15 to facilitate locking the turntable 11 so as to achieve the effect of emergency stop of the fault.
[0041] As Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 shown, the locking mechanism 16 penetrates through one side of the storage cylinder 1 and is connected to one of the support plates 6. The locking mechanism 16 includes a slide rail 1601, and the slide rails 1601 are symmetrically fixed on both sides of one end face of one of the support plates 6. A first compression spring 1602 is fixed on an inner wall of the slide rail 1601, and a rotating sleeve 1603 is fixed between the two first compression springs 1602. The rotating sleeve 1603 is slidably connected between the two slide rails 1601, and a blocking block 1604 is fixed on an inner wall of the rotating sleeve 1603. A limiting rod 1605 is fixed on one side of the rotating sleeve 1603, and the limiting rod 1605 penetrates through the moving plate 1606. A bolt 1607 is fixed on one side of the moving plate 1606. A first through hole 1608 is formed on the rotating sleeve 1603, and the bolt 1607 penetrates through the first through hole 1608. When the motor 7 fails and causes the winding rod 8 and the turntable 11 to rotate rapidly, the rotating block 13 rotates out of the second groove 12, and the blocking block 1604 plays a role in blocking the rotating block 13. The rotating block 13 pushes the blocking block 1604 to move, and the rotating sleeve 1603 rotates between the two slide rails 1601, thereby driving the moving plate 1606, the connecting rod 1613 and the convex block 1615 to rotate as a whole.
[0042] Further, a fixing block 1609 is fixed on an inner wall of the storage cylinder 1, and one side of the fixing block 1609 is connected to an abutting ring 1611 through a second compression spring 1610. A ball 1612 is movably connected to one end face of the abutting ring 1611. A connecting rod 1613 is fixed on the other side of the moving plate 1606. A second through hole 1614 is formed in the fixing block 1609. The connecting rod 1613 passes through the abutting ring 1611, the second through hole 1614 and one side of the storage cylinder 1 and is connected to a handle 1616. A convex block 1615 is fixed on the outer side of the connecting rod 1613. An abnormal rotation speed of the turntable 11 will cause the rotating block 13 to open. After that, the rotating block 13 will push the blocking block 1604 to move, and the rotating sleeve 1603 rotates, thereby driving the moving plate 1606 to rotate. The abutting ring 1611 does not rotate, and the ball 1612 rolls, which is convenient for reducing the friction between the moving plate 1606 and the abutting ring 1611 and making the rotation of the moving plate 1606 smoother. The connecting rod 1613 and the convex block 1615 will rotate together with the moving plate 1606. After the rotating sleeve 1603 rotates to the end, the convex block 1615 corresponds to the second through hole 1614. The abutting ring 1611 bounces to the left under the propping action of the second compression spring 1610. The convex block 1615 passes through the second through hole 1614, and the moving plate 1606 and the latch 1607 move to the left as a whole. The latch 1607 finally snaps into the corresponding slot 15, which is convenient for locking the turntable 11.
[0043] As Figure 1 shown, a battery pack 17 is fixed inside the bottom of the storage cylinder 1, and the battery pack 17 is electrically connected to a motor 7, a camera 908 and a lighting lamp 909. The battery pack 17 can convert direct current into alternating current under the action of an inverter for the use of the whole device, so as to ensure the normal operation of the device.
[0044] Working principle: When using the anti-wear and portable rope ladder, hold the handle 2 to lift the device, hang the hook 3 on the relevant equipment, and then use the threaded rod 4 and the abutting block 5 to fix the device on the equipment. Rotating the winding rod 8 can release or wind the suspension rope 901. During the process of releasing the suspension rope 901, the camera 908 and the lighting lamp 909 can be used to observe the distance between the bottom ladder rod 902 and the ground. After releasing the suspension rope 901 for a certain length, people can climb up along the ladder rod 902. When the motor 7 accidentally fails, the winding rod 8 and the turntable 11 rotate rapidly. When the rotation speed of the turntable 11 reaches a certain value, the rotating block 13 automatically opens and pushes the blocking block 1604 to move. At this time, the rotating sleeve 1603 rotates, driving the whole moving plate 1606 and the connecting rod 1613 to rotate. After the convex block 1615 aligns with the second through hole 1614, the abutting ring 1611 is bounced off by the second compression spring 1610, and the moving plate 1606 moves to the left. The convex block 1615 passes through the second through hole 1614, and the bolt 1607 finally snaps into the corresponding card slot 15 to lock the turntable 11, achieving the effect of emergency stop in case of failure. After completing the fault repair operation, hold the handle 1616 and pull the connecting rod 1613 and the moving plate 1606 to the right to make the bolt 1607 leave the card slot 15. The rotating sleeve 1603 will rotate back under the action of the first compression spring 1602, and the rotating block 13 will reset and retract into the second groove 12 under the action of the scroll spring 14. Then the turntable 11 can continue to rotate normally. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
