Description

Technical Field

[0001] This utility model relates to the field of high-rise escape technology, specifically to a reciprocating high-altitude descent device. Background Technology

[0002] A reciprocating descent device is a personal descent device primarily used for high-altitude work or emergency escape scenarios. Its core feature is that it allows users to safely and steadily perform repeated descents and brief ascents under control, making it more flexible and practical compared to traditional descent devices that can only reach the bottom in one go.

[0003] Existing technologies, such as the utility model patent with publication number CN221771358U, describe a high-rise escape reciprocating descent device, which includes a mounting frame, a drive motor, a controller, an energy storage battery, a planetary reducer, a rope winding drum, a reciprocating screw mechanism, a synchronous belt transmission assembly, a rope guide mechanism, a cable, and a hook. The drive motor, the controller, and the energy storage battery are all fixedly mounted on the mounting frame, and the planetary reducer is mounted on the drive end of the drive motor. This utility model uses the rotation of the drive motor to drive the planetary reducer to rotate. Under the action of the planetary reducer, the rope winding drum begins to rotate, and under the transmission action of the synchronous belt transmission assembly, the reciprocating screw mechanism operates. The rope guide mechanism always presses down on the cable on the rope winding drum, thereby facilitating the control of the cable winding sequence and the speed of winding and unwinding. This avoids the steel wire rope directly contacting and rubbing against the building wall, ensuring that the high-rise escape reciprocating descent device can be reused and has a high safety factor.

[0004] The high-altitude descent device uses multiple mechanisms and components, which increases the complexity of the structure and requires frequent inspection and maintenance. Furthermore, the reciprocating screw mechanism is driven by a synchronous belt drive assembly, which means that only a single layer of cable can be wound on the winding drum, thus limiting the applicable height of the device.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this utility model is to provide a reciprocating high-altitude descent device that can effectively solve the above-mentioned technical problems.

[0007] To achieve the purpose of this utility model, the following technical solution is adopted: a reciprocating high-altitude descent device, comprising: a mounting frame, and a reciprocating mechanism that enables the descent device to reciprocate;

[0008] The reciprocating mechanism includes: a guide rod, on which a movable frame is slidably mounted; a first pulley is rotatably mounted inside the movable frame; a cable passes between the first pulleys; traction ropes are fixedly connected to both sides of the movable frame; the traction ropes pass through a second pulley and are fixedly connected to another movable frame.

[0009] Furthermore, the cable is wound around a winding drum, and both ends of the cable pass through the two moving frames respectively.

[0010] Furthermore, both ends of the winding drum are mounted in bearings, and the bearings are mounted on the mounting bracket.

[0011] Furthermore, the length of the winding roller is less than the length of the guide rod.

[0012] Furthermore, the first pulley is parallel to the central axis of the winding drum.

[0013] Furthermore, braking components are installed at both ends of the winding roller.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention is a reciprocating high-altitude descent device. When one end of the cable descends, the cable drives the winding drum to rotate, so that the winding drum winds up the other end of the cable. The cable release drives the moving frame at the release end to move. This moving frame drives another moving frame to move through the traction rope, so that the winding drum can wind up the cable evenly without affecting the multi-layer winding of the cable, thus improving the practicality of the device.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0021] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. When a mechanism is referred to as being "fixed to" another mechanism, it can be directly on the other mechanism or there may be an intervening mechanism. When a mechanism is considered to be "connected" to another mechanism, it can be directly connected to the other mechanism or there may be an intervening mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it can be directly set on the other mechanism or there may be an intervening mechanism at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0022] like Figures 1 to 3 As shown, this utility model discloses a reciprocating high-altitude descent device, comprising: a mounting frame 1, and a reciprocating mechanism 4 that enables the descent device to reciprocate; the top of the mounting frame 1 is slidably mounted in a mounting rail 6, and the mounting rail 6 is provided with a limiting groove, in which a limiting block 7 is slidably mounted, thereby limiting and fixing the position of the mounting frame 1 by the limiting block 7, so that the high-altitude descent device can extend out of the high-rise building, avoiding the user from contacting the high-rise building wall and causing injury during escape, and the reciprocating mechanism 4 enables the high-altitude descent device to reciprocate, allowing for multiple uses and improving escape efficiency.

[0023] The reciprocating mechanism 4 includes: guide rods 41, both ends of which are fixedly connected to the two ends of the inner wall of the mounting frame 1; multiple guide rods 41 are provided and divided into two groups; a movable frame 42 is slidably mounted on each group of guide rods 41; the multiple guide rods 41 limit the movement of the movable frame 42 to prevent rotation and improve its stability; multiple first pulleys 43 are rotatably mounted inside the movable frame 42; the first pulleys 43 are divided into two groups and located at the upper and lower ends inside the movable frame 42; the two groups of first pulleys 43 are aligned vertically; and two first pulleys in one group... A cable 3 passes between pulleys 43, and mounting blocks 31 are fixedly connected to both ends of the cable 3. A safety belt is installed on the mounting block 31 to secure the user and reduce the usage conditions. A traction rope 44 is fixedly connected to both sides of the mobile frame 42. The two traction ropes 44 are located in the same horizontal plane. The traction rope 44 passes through the second pulley 45 and is fixedly connected to the other mobile frame 42. Each traction rope 44 passes through two second pulleys 45, so that the traction rope 44 undergoes two turns, thereby enabling the other mobile frame 42 to move by means of the traction rope 44 when one mobile frame 42 moves.

[0024] The cable 3 is wound around the winding drum 2, and the two ends of the cable 3 pass through two movable frames 42 respectively. The position of the cable 3 is corrected by the first pulley 43 in the movable frame 42 to avoid the cable 3 rubbing against the high-rise wall, which would cause damage to the cable 3 and affect the escape safety. The two ends of the winding drum 2 are installed in bearings 21, which are installed on the mounting frame 1. The bearings 21 reduce the rotational resistance of the winding drum 2, prevent the two ends of the winding drum 2 from wearing and causing the winding drum 2 to shake on the mounting frame 1, and ensure the stability of the winding drum 2.

[0025] Furthermore, the length of the winding drum 2 is less than the length of the guide rod 41, so that the range of the moving frame 42 is greater than the range of movement of the cable 3 during the winding process. This allows the moving frame 42 to move along with the cable 3 as it is unloaded. The moving frame 42 pulls the traction rope 44, which in turn pulls another moving frame 42, so that the winding drum 2 can evenly wind up the cable 3.

[0026] It should be noted that when the cable 3 is being laid out, the angle between the cable 3 and the moving frame 42 changes. The first pulley 43 is set to be parallel to the central axis of the winding drum 2 so that the moving frame 42 can accommodate the multi-layer wound cable 3 and avoid the cable 3 from rubbing against the moving frame 42 after the angle changes, which would cause the cable 3 to wear.

[0027] Furthermore, braking components 5 are installed at both ends of the winding drum 2. Each braking component 5 includes: a rotating shaft 51, which is fixedly connected to both ends of the winding drum 2 with their central axes aligned; an outer sleeve rod 52 is fixedly installed on the side of the rotating shaft 51; a sliding rod 53 is slidably installed within the outer sleeve rod 52; a spring 54 is sleeved on the sliding rod 53; and a braking block 55 is fixedly connected to the sliding rod 53. One end of the spring 54 is fixedly connected to the outer sleeve rod 52, and the other end of the spring 54 is fixedly connected to the braking block 55. Sleeves 56 are fixedly installed at both ends of the mounting frame 1. The high-speed rotation of the winding drum 2 causes the winding drum 2 to drive the rotating shaft 51 to rotate. The rotating shaft 51 drives the outer sleeve rod 52 to rotate. The outer sleeve rod 52 drives the sliding rod 53 to rotate. Under the action of centrifugal force, the sliding rod 53 overcomes the elastic force of the spring 54, causing the brake block 55 to contact and rotate with the inner wall of the sleeve 56. The friction generated hinders the rotation of the brake block 55. The faster the rotation speed of the winding drum 2, the greater the centrifugal force and the greater the friction, which stabilizes the user's descent speed and ensures the user's safety.

[0028] Working principle:

[0029] After the user secures their safety belt, they descend. As one end of the cable 3 descends, the cable 3 drives the winding drum 2 to rotate, causing the winding drum 2 to wind up the other end of the cable 3. Simultaneously, the brake 5 brakes the winding drum 2, stabilizing its speed and allowing the user to descend at a safe speed. The safety belt at the other end of the cable 3 can be used by another user immediately after one user touches the ground, eliminating the need for the device to rewind the cable 3, thus improving escape efficiency. Furthermore, the release of the cable 3 drives the movement of the movable frame 42 at the release end. This movable frame 42, via the traction rope 44, moves another movable frame 42, ensuring that the winding drum 2 can evenly wind up the cable 3 without affecting the multi-layer winding of the cable 3. This allows the device to be used in higher environments, improving its practicality.
