Description

Technical Field

[0001] This utility model relates to the field of rope descender technology, specifically a rope descender locking and high-efficiency ascending device. Background Technology

[0002] A descent device is an essential safety piece of equipment in rope work, and its internal structure and working principles involve multiple disciplines, such as physics, design, and materials science. The goal of a descent device is to manage the descent speed of the rope while ensuring the safety of the user.

[0003] Based on the above, the inventors have discovered the following problems: Current rope descenders are generally designed to increase rope friction to enhance cushioning, thereby achieving deceleration or locking. However, with the widespread application of rope work, especially in rope rescue, the increased weight of users, such as when multiple users are using the device simultaneously in rescue operations, can lead to problems like slippage, difficulty in transitioning between descent and ascent, and excessive slippage during the transition from ascent to descent, causing panic among personnel. These issues all affect user safety to some extent and are problems that require special attention in the design of rope descenders.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a rope descender locking and high-efficiency ascending device in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a rope descender locking and high-efficiency ascending device to solve the problems mentioned in the background art.

[0006] A rope descender locking and high-efficiency ascending device includes a fixed integration and a rotating integration. The fixed integration includes a mounting plate and a fixed friction block. The mounting plate is provided with a connector and a sliding groove.

[0007] The rotating assembly includes a pulley, a drive shaft, a rotating plate, a bearing, a movable friction block, and a ratchet mounting component. The pulley and ratchet mounting component are assembled on the rotating plate. The drive shaft passes through the sliding groove. One end of the rotating plate is rotatably assembled on one end of the assembly plate via a first connecting shaft. The other end of the rotating plate is connected to one end of the drive shaft.

[0008] The ratchet mounting component is disposed inside the rope pulley and is coaxially rotatably connected to the rope pulley. The ratchet mounting component is provided with at least one ratchet groove, and a ratchet is assembled in each ratchet groove. One end of the ratchet is located in the ratchet groove, and the other end protrudes from the ratchet groove. At least one step is provided on the inner wall of the rope pulley.

[0009] Furthermore, each of the ratchet grooves is also fitted with a spring, one end of which is connected to the ratchet tooth, and the other end of which is fitted into the ratchet groove.

[0010] Furthermore, the number of steps is greater than the number of ratchet grooves.

[0011] Furthermore, the number of steps includes 5 or more and 8 or less, and they are evenly distributed along the inner wall of the rope wheel; the number of ratchet grooves includes 3 or 4, and they are evenly distributed around the ratchet mounting component.

[0012] Furthermore, the middle part of the rope wheel is sleeved on the outside of the first connecting shaft, and the bearing is located in the middle part of the rope wheel.

[0013] Furthermore, it also includes a cover plate integration, which includes a cover plate and a locking post. The cover plate has a locking groove on its side. The cover plate is rotatably mounted on the assembly plate via a second connecting shaft. The locking post passes through the locking groove and engages with the first connecting shaft.

[0014] Furthermore, a rope groove is provided on the outer side of the rope pulley.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: When the user drags the rope end, the rope wheel rotates efficiently with the assistance of the bearing under the dragging force, thereby releasing the rope from its locked state and enabling a transition from the descent to the ascent state. When the dragging force on the rope end disappears, the rope wheel rotates clockwise, and the ratchet assembly relocks. The user's weight applies a clockwise force to the rope wheel, causing the rotation to be integrated clockwise under the rope's action, reducing the gap between the moving and fixed friction blocks, locking the rope, and thus ensuring the rope descender remains locked to the rope without movement, providing high safety.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] The fixed integration 2 mainly includes an assembly plate 25 and a fixed friction block 22. The assembly plate 25 is provided with a connector 21 and a sliding groove 23. The fixed friction block 22 and the assembly plate 25 can also be made as a single unit. The connector 21 is used for connection with the user and is typically... Figure 2 The hanging ring structure shown.

[0026] The rotating assembly 3 mainly includes a rope wheel 31, a drive shaft 32, a bearing 37, a movable friction block 38, and a rotating plate 33. The rope wheel 31 and the ratchet mounting part 34 are assembled on the rotating plate 33. The drive shaft 32 passes through the sliding groove 23. One end of the rotating plate 33 is rotatably assembled on the mounting plate 25 through the first connecting shaft 81, and the other end is connected to one end of the drive shaft 32. The other end of the drive shaft 32 is assembled with the handle assembly 4.

[0027] The cover plate 11 is rotated and fitted via the second connecting shaft 82, which allows the cover plate 11 and the fixed friction block 22 to be assembled onto the mounting plate 25 together. A slot 12 is provided in the middle area of ​​the cover plate 11, and a locking post 13 is provided on the first connecting shaft 81 corresponding to the slot 12. When the cover plate 11 rotates around the second connecting shaft 82, and the slot 12 and locking post 13 engage, the cover plate 11 is in a closed state, sealing the rotating assembly 3 and further preventing the rope 5 from falling off, thereby improving the safety of the rope descender. When the cover plate 11 rotates to the left and is in an open state, the rope 5 can be easily assembled onto the rope descender.

[0028] When the rope descender is in use, the rope end 51 of the rope 5 passes through the gap 6 between the movable friction block 38 and the fixed friction block 22 after wrapping around the rope pulley 31. The rope pulley 31 may be further provided with a rope groove 311 around its periphery. As the rope 5 travels through the rope descender, it is primarily positioned within the rope groove 311, thereby further improving the stability of the rope 5 within the rope descender and effectively preventing slippage.

[0029] To increase the friction force experienced by the rope 5 during travel, the positions of the rope pulley 31, sliding groove 23, and fixed friction block 22 are configured such that when the rope 5 is pulled straight in the vertical direction, the distance from the center of the left rope to the first connecting shaft 81 is greater than the distance from the center of the right rope to the second connecting shaft 82 when viewed from the direction facing the rope pulley 31. This eccentric design can effectively utilize the user's gravity to push the movable friction block 38 towards the fixed friction block 22 through the rope 5, thereby effectively reducing the gap 6 and increasing the friction force on the rope 5.

[0030] Specifically, when the user connects to the rope descender via connector 21, the user's weight is applied to the rope descender through connector 21. The user's weight applies a clockwise pushing force to the movable friction block 38, causing one end of the rotating assembly 3 and the drive shaft 32 to rotate clockwise along the sliding groove 23, that is, to rotate closer to the friction block 22. The gap 6 between the movable friction block 38 and the fixed friction block 22 is reduced accordingly, and the rope pulley 31 and the fixed friction block 22 press the rope 5 together, thereby locking the rope 5. The rope descender stops moving on the rope when the rope 5 is locked.

[0031] Furthermore, the dimensions and positional relationship of the sliding groove 23, the fixed friction block 22, and the movable friction block 38 are preferably configured such that when the drive shaft 32 is close to the end of the sliding groove 23 away from the fixed friction block 22, the gap 6 between the movable friction block 38 and the fixed friction block 22 allows the rope 5 to pass smoothly, and when the drive shaft 32 is close to the other end of the sliding groove 23 near the fixed friction block 22, the gap 6 between the movable friction block 38 and the fixed friction block 22 can lock the rope 5.

[0032] This embodiment also adds a ratchet mounting component 34 to the rotation integration 3. The ratchet mounting component 34 is assembled in the rope pulley 31. The ratchet teeth 35 inside the ratchet mounting component 34 can restrict the unidirectional rotation of the rope pulley 31, allowing the rope pulley 31 to rotate only when the device is ascending along the rope. The rolling friction of the bearing 37 replaces the sliding friction between the ratchet mounting component 34 and the rope pulley 31, greatly improving the rotation efficiency of the rope pulley 31. When the ratchet mounting component 34 descends along the rope 5, it restricts the rotation of the rope pulley 31 and keeps the rope pulley 31 stationary. This achieves a rapid transition from the descending to the ascending state and also ensures the friction between the rope pulley 31 and the fixed friction block on the rope 5 during the descent. The asynchronous design of multiple ratchet teeth 35 allows the rope pulley 31 to lock with a small rotation angle, reducing the slippage of the descent device.

[0033] The ratchet mount 34 is located in the pulley 31 and is coaxially assembled with the pulley 31. The ratchet mount 34 has at least one ratchet groove 341; for example, in this embodiment, the ratchet mount 34 has three ratchet grooves 341. Each ratchet groove 341 is fitted with a set of ratches 35 and a spring 36 to limit the rotation direction of the pulley 31. Figure 6 As shown, at least one step 312 is also provided along the inner wall of the rope pulley 31. A preferred configuration is that the number of steps 312 is greater than the number of ratchet grooves 341, for example... Figure 5 The number of steps 312 shown is 8. Preferably, the ratchet grooves 341 and steps 312 are evenly distributed. Each ratchet groove 341 has a certain slope.

[0034] One end of the ratchet 35 is located in the ratchet groove 341, and the other end protrudes from the ratchet groove 341. The bottom of the ratchet groove 341 can be slightly larger than the opening. The end of the ratchet 35 located at the bottom of the groove cooperates with the bottom structure of the ratchet groove 341, and is slightly larger than the end protruding from the opening. This structure can effectively limit the ratchet 35 in the ratchet groove 341.

[0035] When the rope pulley 31 descends along the rope 5, at least one ratchet 35 will be engaged between the step 312 and the ratchet groove 341 to limit the rotation of the rope pulley 31. When the rope is pulled from the direction of the rope exiting the gap 6, the rope pulley 31 will rotate with the rope 5.

[0036] The following is in conjunction with the appendix Figure 6 This section details the working principle of the ratchet assembly that restricts the unidirectional rotation of the pulley 31. (Focusing on...) Figure 6When viewed from the indicated direction, when the pulley 31 rotates clockwise, the protruding end of the ratchet 35 passes over the step 312 on the inner wall of the pulley 31 in sequence, without affecting the clockwise rotation of the pulley 31. When the pulley 31 rotates counterclockwise, as long as one protruding end of the ratchet 35 is caught by the step 312, the ratchet 35 is locked by the step 312 and the ratchet groove 341, and the pulley 31 is in a locked state, preventing the pulley 31 from rotating.

[0037] The spring 36 pushes the ratchet 35 more smoothly from the step 312 surface when the rope wheel 31 rotates clockwise, and when the rope wheel 31 rotates counterclockwise, it can push the ratchet 35 to better abut against the step 312.

[0038] In summary, the rope descender locking and high-efficiency ascending device provided in this embodiment allows the rope wheel 31 to rotate efficiently counterclockwise under the dragging force and with the assistance of the bearing 37 when the user is pulling the rope end 51. This releases the locked state of the rope 5, enabling the transition from the descending state to the ascending state. When the dragging force on the rope end 51 disappears, the rope wheel 31 rotates clockwise, and the ratchet assembly relocks. The rope 5 exerts a clockwise force on the rope wheel 31 due to the user's weight, causing the rotating assembly 3 to rotate clockwise under the action of the rope 5. This reduces the gap 6 between the movable friction block 38 and the fixed friction block 22, locking the rope 5 and thus locking the rope descender onto the rope 5 without movement.

[0039] In the rope descender provided in this embodiment, the number of ratchet grooves 341 can be greater than the number of steps 312. The ratchet grooves 341 include three evenly distributed around the periphery of the ratchet mounting member 34, while the steps 312 can be five to eight evenly distributed along the inner wall of the rope pulley 31. The number of ratches 35 and steps 312 does not correspond synchronously. When the rope pulley 31 changes from counter-clockwise to clockwise rotation, locking any one of the three ratches will lock the rope pulley 31, ensuring that the rope pulley 31 rotates to the minimum angle required for locking. The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
