Description

Technical Field

[0001] The utility model belongs to the field of rope rescue technology and high-altitude rope technology, in particular to a safety rope controller. Background Art

[0002] Currently, there are two common devices on the market: one-way locking pulleys and descenders. Among them, as for one-way locking pulleys, the one-way locking pulleys on the market do not have the function of a descender. If you want to achieve the purpose of a descender, you often need a pulley with a one-way locking function or similar functions. Usually, it requires a system to complete, which is cumbersome to operate and prone to failure. In addition, when the existing pulley device is used to lift heavy objects, the one-way locking strength is insufficient and it is very easy to cause the risk of rope loss of control during the release process. In addition, it does not meet the function of personnel descent.

[0003] In addition, as for descenders, existing descenders all use the friction principle to clamp the rope to ensure that the user does not fall at a high speed, but when the user wants to ascend, the existence of friction will greatly reduce the efficiency of ascent.

[0004] Therefore, in order to improve efficiency and safety, there is an urgent need to design a one-way pulley device that does not require a system assembly and is easy to operate. At the same time, it can meet the requirements of saving efficiency when the rope is ascending and serving as a rope controller used as a pulley descender to ensure safety when descending. Utility Model Content

[0005] The technical problem to be solved by the utility model is that the descender is affected by friction during ascent, the ascent efficiency is greatly reduced, and the ascent safety factor is not high.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: A safety rope controller proposed in the present invention includes a panel, a rotating shaft is provided at the lower end of the panel, the other end of the rotating shaft is connected to a back plate, an eccentric slide groove for descent adjustment is provided on the back plate, a descent component is connected to the back plate, and the descent component and the eccentric slide groove for descent adjustment are eccentrically connected, a rope fixing block is installed on the side of the back plate close to the panel, a one-way bearing is rotated between the panel and the back plate, a roller is wrapped on the outer side of the one-way bearing, an eccentric shaft component is provided in the roller, the eccentric shaft component is connected to the descent component, and the one-way bearing controls the roller to move only in one direction.

[0007] As an improvement, the descending assembly includes a descending handle, a handle pin and an eccentric linkage pin. The descending handle is arranged on the back plate. The handle pin passes through the descending handle and is rotatably connected to the back plate. The eccentric linkage pin is arranged on the descending handle and passes through the descending adjustment eccentric slide groove and the eccentric shaft component. The descending handle drives the entire one-way bearing and roller to move to achieve the purpose of locking and releasing the rope. The eccentric shaft component connects the one-way bearing and the descending handle to achieve the purpose of moving the eccentric linkage pin by rotating the descending handle, and finally locking or releasing the rope.

[0008] As an improvement, when the distance between the descending adjustment eccentric chute and the roller is reduced, the rope is blocked by friction.

[0009] As an improvement, the surface of the roller is treated to increase friction and is installed on the eccentric shaft component together with a one-way bearing. When the rope is pulled upward, it can rotate freely, but when the rope slides downward, it will drive the eccentric shaft component to reduce the distance between the roller and the rope fixing block, jamming the rope and preventing it from sliding.

[0010] As an improvement, a one-way locking block is further provided in the front panel and the back panel, and the one-way locking block controls the roller to rotate in only one direction, and makes a "clicking" sound when the roller rotates.

[0011] As an improvement, a panel unlocking button is provided on the panel, and the panel unlocking button is used to lock the panel.

[0012] The beneficial effects achieved by the utility model using the above structure are as follows: a safety rope controller proposed in this scheme controls the roller to move in only one direction through the one-way locking block, thereby improving the efficiency of pulling upward and providing safety performance that will not fall. At the same time, a visible clicking sound is emitted when pulling, helping workers to distinguish whether the pull is in progress, especially when the rope is too long and out of sight; the roller is installed on the eccentric linkage pin, and when the rope moves, the eccentric linkage pin drives the distance between the roller and the rope fixing block to change, so as to lock or release the rope, thereby meeting the function of pulling the rope in one direction and achieving the purpose of being used as a one-way pulley;

[0013] In addition, when descending by rope, the internal eccentric linkage pin design will drive the eccentric linkage pin to move as the rope slides downward to clamp the rope with friction, ensuring that the rope will not slip; at the same time, a descending handle is provided on the outside of the pulley descender, which can drive the roller to move along the eccentric linkage pin, expand the distance between the roller and the rope fixing block, and enable the rope to slide, satisfying the function of rope descent and achieving the purpose of being used as a descender.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0020] like Figure 1-4 As shown, the utility model proposes a safety rope controller, including a panel 1, a rotating shaft 2 is rotated at the lower end of the panel 1, the other end of the rotating shaft 2 is connected to a back plate 3, the back plate 3 is provided with a descending adjustment eccentric slide 4, a descending component 5 is connected to the back plate 3, and the descending component 5 and the descending adjustment eccentric slide 4 are eccentrically connected, a rope fixing block 6 is installed on the side of the back plate 3 close to the panel 1, a one-way bearing 7 is rotated between the panel 1 and the back plate 3, the outer side of the one-way bearing 7 is wrapped with a roller 8, an eccentric shaft component 9 is provided in the roller 8, the eccentric shaft component 9 is connected to the descending component 5, and the one-way bearing 7 controls the roller 8 to move only in one direction.

[0021] like Figure 3 、 4 As shown, the descent assembly 5 includes a descent handle 10, a handle pin 11 and an eccentric linkage pin 12. The descent handle 10 is arranged on the back plate 3. The handle pin 11 passes through the descent handle 10 and is rotatably connected to the back plate 3. The eccentric linkage pin 12 is arranged on the descent handle 10 and passes through the descent adjustment eccentric slide groove 4 and is connected to the eccentric shaft component 9. The descent handle 10 drives the entire one-way bearing 7 and the roller 8 to move to achieve the purpose of locking and releasing the rope. The eccentric shaft component 9 connects the one-way bearing 7 and the descent handle 10 to achieve the purpose of moving the eccentric linkage pin 12 by rotating the descent handle 10, and finally locking or releasing the rope.

[0022] like Figure 1 、 2 As shown in Figures 3 and 4, when the distance between the eccentric chute 4 and the roller 8 is reduced, the rope is stuck due to friction; the surface of the roller 8 is treated to increase friction, and it is installed on the eccentric shaft component 9 together with the one-way bearing 7. When the rope is pulled upward, it can rotate freely, but when the rope slides downward, it will drive the eccentric shaft component 9 to reduce the distance between the roller 8 and the rope fixing block 6, thereby blocking the rope and preventing it from sliding.

[0023] like Figure 3 As shown, a one-way locking block 13 is further provided in the front panel 1 and the back panel 3. The one-way locking block 13 controls the roller 8 to rotate in only one direction and makes a "clicking" sound when the roller 8 rotates.

[0024] like Figure 2 As shown, a panel unlocking button 14 is provided on the panel 1 , and the panel unlocking button 14 is used to lock the panel 1 .

[0025] When in use, the panel unlocking button 14 is pressed to release the locking force between the panel 1 and the back panel 3, so that the back panel 3 can rotate around the panel 1, and the internal structure installed on the back panel 3 is exposed. Then the user winds the rope around the left side of the roller 8 and upwards from between the roller 8 and the rope fixing block 6. After closing the panel 1, the rope is stuck between the roller 8 and the rope fixing block 6. When rising, the rope is pulled upward. Under the action of friction, the rope pulls the roller 8 and the one-way bearing 7 to rotate in one direction, and the one-way locking block 13 is set. When the vehicle is lowered, a "clicking" sound is emitted, thereby achieving the purpose of ascending; when descending, the descending handle 10 is opened, and the descending handle 10 rotates around the handle pin 11 on the back plate 3, and slides eccentrically in the descending adjustment eccentric slot 4 with the eccentric linkage pin 12, thereby driving the eccentric shaft component 9 and the descending handle 10 to rotate eccentrically in the same direction. As the eccentric shaft component 9 rotates eccentrically and is displaced under the action of the descending adjustment eccentric slot 4, the distance between the linkage roller 8 and the rope fixing block 6 increases, thereby achieving the purpose of releasing the rope to descend.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.

[0027] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
