Description

Technical Field

[0001] This utility model relates to the field of riser technology, specifically to a dual-drive riser. Background Technology

[0002] Dual-drive ascenders are core equipment in high-altitude operations, fire rescue, mountain climbing, and industrial safety, and their performance directly affects operational efficiency and personnel safety. As human activities continue to expand into extreme environments, such as high-altitude snow-capped mountains, complex rock faces, damp caves, or disaster relief sites, higher demands are placed on the reliability, adaptability, and environmental tolerance of ascenders. While traditional ascenders can achieve basic climbing functions, they still have significant limitations when facing variable weather, complex media, and long-term continuous operations. Against this backdrop, improving the stability and durability of equipment under harsh conditions through structural innovation has become a key direction for technological iteration in the industry. In recent years, many improvements have emerged in areas such as drive efficiency, human-machine interaction, and lightweight design; however, a systematic solution is still lacking for controlling contamination at the ascender's rope inlet, a critical aspect affecting core functionality.

[0003] In existing technologies, when ascenders are used in harsh environments such as outdoor operations, emergency rescue, or high-altitude climbing, the surface of the rope is easily contaminated with pollutants such as mud, water, and frost. If these pollutants enter the ascender's interior with the rope, they will significantly aggravate the wear of the internal drive and locking mechanisms, leading to increased operating resistance, decreased locking reliability, and even equipment jamming or malfunction. This seriously affects the safety and lifespan of the ascender. Although some existing products attempt to alleviate this problem through fixed cleaning structures, these structures are often non-removable, have limited cleaning effects, and lack adaptability to ropes of different diameters or surface shapes, making it difficult to achieve effective and durable protection in practical applications.

[0004] Therefore, it is necessary to provide a crystallization tank that facilitates material discharge to solve the above-mentioned technical problems. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the existing technology, this utility model provides a crystallization tank that facilitates material discharge and can clean sludge and other impurities in the riser.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A crystallization tank for easy discharge includes: an ascender and a mounting base. The ascender is equipped with a rope inlet, and the mounting base can be rotatably sleeved on the rope inlet by means of a threaded connection. The mounting base is equipped with multiple sets of annularly distributed adjustment plates. Each set of adjustment plates has a brush strip fixedly attached to it to wrap and clean the surface of the rope. The multiple sets of adjustment plates are rotatably connected to the mounting base through a mounting shaft. The mounting base is equipped with a locking mechanism to lock the angle of the adjustment plate; Preferably, a mounting ring is rotatably mounted inside the mounting base, a gear ring is sleeved on the mounting ring, multiple sets of mounting shafts are distributed in a ring around the mounting ring, and a first gear is sleeved on each of the multiple sets of mounting shafts, and the multiple sets of first gears are meshed with the gear ring.

[0007] Preferably, the two adjacent sets of adjustment plates are staggered in the vertical direction, and a first torsion spring is sleeved on the mounting shaft. The two ends of the first torsion spring are fixedly connected to the corresponding adjustment plate and the mounting base, respectively.

[0008] Preferably, the locking mechanism includes two sets of check wheels symmetrically sleeved on the right mounting shaft. Two sets of check claws corresponding to the check wheels are installed in the mounting base. The two sets of check claws are meshed with the corresponding check wheels. Both sets of check claws are rotatably connected to the mounting base through rotating rods. A second gear is sleeved on each of the two rotating rods. Two sets of racks that mesh with the second gears are slidably installed in the mounting base.

[0009] Preferably, a second torsion spring is sleeved on the rotating rod, and the two ends of the second torsion spring are fixedly connected to the anti-return pawl and the mounting base, respectively.

[0010] Preferably, a connecting frame is slidably installed inside the mounting base, the connecting frame is fixedly connected to two sets of racks respectively, and a sliding rod is fixedly installed inside the mounting base, with the connecting frame and the sliding rod slidably connected.

[0011] Preferably, two sets of symmetrically distributed springs are sleeved on the slide rod, and the two ends of the two sets of springs are fixedly connected to the connecting frame and the mounting base, respectively. A locking block is fixedly installed on the connecting frame.

[0012] Preferably, a locking rod corresponding to the locking block is fixedly installed inside the mounting base. Two sets of symmetrically distributed locking clips are sleeved on the locking rod. The two sets of locking clips can be movably engaged with the locking block. A third torsion spring is sleeved on the locking rod. The two ends of the third torsion spring are fixedly connected to the corresponding locking clips and the locking rod, respectively.

[0013] Compared with the prior art, the present invention has the following beneficial effects: (1) This utility model has multiple sets of ring-shaped adjustment plates with brush strips in the mounting base, which can fully wrap and efficiently clean the surface of the rope when it passes through, effectively removing adhering mud, water, frost and other pollutants, and preventing pollutants from entering the inside of the riser. (2) The locking mechanism of this utility model can quickly switch the working state of the adjustment plate by simply pulling; pulling the connecting frame drives the rack to move, so that the locking block is locked into the two sets of clamps, and the anti-return claw can disengage from the anti-return wheel. At this time, the mounting shaft and the adjustment plate can rotate freely, which is convenient for adjusting or replacing the rope; pulling the connecting frame in the opposite direction, the clamps release the locking block, and under the action of the spring and the second torsion spring, the anti-return claw automatically returns to its position and meshes with the anti-return wheel, thereby achieving reliable locking of the mounting shaft, thus fixing the working position of the adjustment plate, ensuring structural stability and reliable anti-loosening during the cleaning process, and improving the convenience of operation and the safety locking performance of the mechanism; (3) This utility model can adaptively adjust the tilt angle by linking the mounting shaft with the gear ring transmission structure, so that the brush strip is always closely attached to the surface of the rope, which significantly improves the adaptability and cleaning effect of ropes with different diameters or surface shapes, and takes into account both the comprehensiveness of protection and the flexibility of use.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0017] First embodiment: like Figure 1-5As shown, a dual-drive ascender includes an ascender 1 and a mounting base 3. The ascender 1 is equipped with a rope inlet 2. The mounting base 3 can be rotatably sleeved on the rope inlet 2 by means of a threaded connection. By means of a threaded connection, the mounting base 3 can be easily installed on or removed from the rope inlet 2 of the ascender 1, which is convenient for users to maintain or replace the cleaning mechanism. Multiple sets of annularly distributed adjustment plates 4 are installed inside the mounting base 3. Each set of adjustment plates 4 has a brush strip 5 fixedly attached to it to wrap and clean the surface of the rope. The multiple sets of adjustment plates 4 are rotatably connected to the mounting base 3 through the mounting shaft 8. The multiple sets of adjustment plates 4 with brush strips 5 are arranged in annularly to accommodate ropes of different diameters. When the rope passes through, the brush strips 5 can effectively scrape off the mud, sand, ice water and other dirt attached to the surface, keep the rope clean and prevent contaminants from entering the interior of the ascender 1. The mounting base 3 is equipped with a locking mechanism 11, which locks the angle of the adjustment plate 4. The locking mechanism 11 can fix or release the rotation angle of the adjustment plate 4, so that the brush strip 5 can be adjusted according to the diameter of the rope and kept in the best wrapping posture, or facilitate the insertion and removal of the rope.

[0018] Second embodiment: like Figure 2 , Figure 3 As shown in the preferred embodiment of this utility model, a mounting ring 6 is rotatably mounted inside the mounting base 3, and a toothed ring 7 is sleeved on the mounting ring 6. Multiple sets of mounting shafts 8 are distributed in a ring around the mounting ring 6, and a first gear 9 is sleeved on each of the multiple sets of mounting shafts 8. The multiple sets of first gears 9 are meshed with the toothed ring 7. Adjacent sets of adjusting plates 4 are staggered in the vertical direction. A first torsion spring 10 is sleeved on the mounting shaft 8. The two ends of the first torsion spring 10 are fixedly connected to the corresponding adjusting plate 4 and the mounting base 3, respectively. When a certain adjusting plate 4 is squeezed and rotated by the rope, the meshing transmission between the first gear 9 and the toothed ring 7 can drive the other adjusting plates 4 to deflect synchronously, so that multiple sets of brush strips 5 work together to evenly cover the surface of the rope. The staggered arrangement improves the comprehensiveness of cleaning. The first torsion spring 10 provides the force for the adjusting plate 4 to automatically reset, ensuring that it stays in contact with the rope.

[0019] Third embodiment: like Figure 4 , Figure 5As shown, in a preferred embodiment of this utility model, the locking mechanism 11 includes two sets of check wheels 1101 symmetrically sleeved on the right mounting shaft 8. Two sets of check claws 1102 corresponding to the check wheels 1101 are installed in the mounting base 3. The two sets of check claws 1102 are meshed with the corresponding check wheels 1101. Both sets of check claws 1102 are rotatably connected to the mounting base 3 via rotating rods 1103. Second gears 1105 are sleeved on both rotating rods 1103. Two sets of racks 1106 meshing with the second gears 1105 are slidably installed in the mounting base 3. Second torsion springs 1104 are sleeved on the rotating rods 1103, and both ends of the second torsion springs 1104 are fixedly connected to the check claws 1102 and the mounting base 3, respectively. A connecting frame 1107 is slidably installed in the mounting base 3, and the connecting frame 1107 is fixedly connected to the two sets of racks 1106, respectively. A sliding rod 1108 is fixedly installed, and a connecting frame 1107 is slidably sleeved with the sliding rod 1108. Two sets of symmetrically distributed springs 1109 are sleeved on the sliding rod 1108. The two ends of the two sets of springs 1109 are fixedly connected to the connecting frame 1107 and the mounting base 3, respectively. A locking block 1110 is fixedly installed on the connecting frame 1107. Under normal conditions, two sets of second torsion springs 1104 drive two sets of check pawls 1102 to mesh with the corresponding check wheels 1101, thereby achieving bidirectional locking of the mounting shaft 8 and the adjusting plate 4 to prevent them from loosening. When adjustment is required, the connecting frame 1107 is pulled outward, which drives the rack 1106 to move. The second gear 1105 drives the rotating rod 1103 to rotate, causing the check pawls 1102 to overcome the force of the second torsion springs 1104 and disengage from the check wheels 1101, thus releasing the lock. The connecting frame 1107 moves while compressing the springs 1109 and driving the locking block 1110 to move.

[0020] Fourth embodiment: like Figure 4 , Figure 5 As shown, in a preferred embodiment of this utility model, a locking rod 1111 corresponding to the locking block 1110 is fixedly installed inside the mounting base 3. Two sets of symmetrically distributed clamps 1112 are sleeved on the locking rod 1111, and the two sets of clamps 1112 can be movably engaged with the locking block 1110. A third torsion spring 1113 is sleeved on the locking rod 1111, and the two ends of the third torsion spring 1113 are fixedly connected to the corresponding clamps 1112 and the locking rod 1111, respectively. When the connecting frame 1107 is pulled out to a certain extent... When in the fixed position, the locking block 1110 is embedded between the two sets of clamps 1112. The clamping force provided by the third torsion spring 1113 keeps it in this stable state. At this time, the locking mechanism 11 is in a continuously released state, which is convenient for operation. Pull the connecting frame 1107 in the opposite direction again, and the locking block 1110 can be disengaged from the clamps 1112. Under the action of the spring 1109, the connecting frame 1107 is reset. The anti-return pawl 1102 re-engages with the anti-return wheel 1101 under the action of the second torsion spring 1104, and the locking function is restored.

[0021] Working principle: Multiple sets of annularly distributed adjusting plates 4 are installed inside the mounting base 3. Each set of adjusting plates 4 has a brush strip 5 fixedly attached to it to wrap and clean the surface of the rope. The multiple sets of adjusting plates 4 are rotatably connected to the mounting base 3 through the mounting shaft 8. The multiple sets of adjusting plates 4 with brush strips 5 are arranged in annularly to accommodate ropes of different diameters. When the rope passes through, the brush strips 5 can effectively scrape off the mud, sand, ice water and other dirt attached to the surface, keep the rope clean and prevent contaminants from entering the interior of the ascender 1.

[0022] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
