Description

Technical Field

[0001] This utility model relates to the field of engineering construction safety technology, and more specifically, to a safety rope connection device for a cap beam. Background Technology

[0002] In the bridge cap beam construction phase, the safety of workers walking and working on the cap beam is a key focus of construction safety management due to its high altitude and lack of edge protection. Safety ropes are required for construction safety, and their proper placement and efficient use are crucial for reducing the risk of falls and improving construction safety. However, the simple structure of the cap beam lacks reliable anchor points for safety ropes, resulting in a significant risk of falls and seriously threatening the lives of workers. Utility Model Content

[0003] The purpose of this utility model is to provide a safety rope connection device for cap beams, which solves the problem of no reliable hanging point for safety ropes in existing cap beam construction.

[0004] This utility model is achieved through the following technical solution: a safety rope connection device for a cap beam, including pre-embedded buckles pre-embedded on the blocks at both ends of the cap beam, a horizontal rope between the pre-embedded buckles, a number of positioning brackets for clamping and fixing the horizontal rope evenly distributed in the middle of the cap beam, an open ring sleeved on the horizontal rope, a limiting ring groove opened in the inner ring of the open ring, a number of balls that roll in contact with the horizontal rope being movably connected in the limiting ring groove, a connecting ring for connecting the safety rope being provided on the outer wall of the open ring, and when the open ring slides along the horizontal rope, the positioning brackets pass through the opening of the open ring and between the adjacent balls.

[0005] Furthermore, the opening of the open ring is shaped like an hourglass, narrow in the middle and gradually widening at both ends, along the axial direction.

[0006] Furthermore, the diameter of the ball is larger than the opening width of the open ring.

[0007] Furthermore, the angle between the line connecting the axes of the connecting ring and the open ring and the central axis at the opening of the open ring is an obtuse angle.

[0008] Furthermore, the two ends of the horizontal rope are secured by rope clamps after passing over pre-embedded buckles.

[0009] Furthermore, at least three rope clamps are provided at the connection between the horizontal rope and the pre-embedded buckle, and the clamp seat of all rope clamps faces the long rope section of the horizontal rope.

[0010] Furthermore, the axial distance between two adjacent rope clamps shall not be less than six times the diameter of the horizontal rope.

[0011] Furthermore, U-shaped steel bars are used for the pre-embedded buckles.

[0012] This utility model has at least the following advantages and beneficial effects: By combining the pre-embedded buckle, horizontal rope, positioning bracket and open ring, a complete safety protection system for the cover beam is constructed. The limiting ring groove in the open ring cooperates with the ball to convert sliding friction into rolling friction, reducing sliding resistance. The positioning bracket can pass through the gap between the opening and the ball to achieve continuous sliding, ensuring uninterrupted protection and effectively reducing the risk of falling from height.

[0021] The specific implementation method is described below with reference to the accompanying drawings.

[0022] Example like Figures 1 to 7As shown, this embodiment mainly discloses a safety rope device for a cap beam 1, including pre-embedded buckles 2 embedded in the end blocks 11 at both ends of the cap beam 1, a horizontal rope 3 between the pre-embedded buckles 2, and a plurality of positioning brackets 31 evenly distributed in the middle of the cap beam 1 for clamping and fixing the horizontal rope 3. An open ring 4 is fitted on the horizontal rope 3, and a limiting ring groove 40 is formed in the inner ring of the open ring 4. A plurality of balls 41 that roll in contact with the horizontal rope 3 are movably connected in the limiting ring groove 40. A connecting ring 42 for connecting the safety rope is provided on the outer wall of the open ring 4. When the open ring 4 slides along the horizontal rope 3, the positioning brackets 31 pass through the opening of the open ring 4 and between the adjacent balls 41. Through the combined structure of the pre-embedded buckles 2, the horizontal rope 3, the positioning brackets 31 and the open ring 4, a complete safety protection system for the cap beam 1 is constructed. The pre-embedded buckle 2 is embedded in the stop blocks 11 at both ends of the cap beam 1, providing a stable fixing foundation for the horizontal rope 3 and solving the problem of no reliable fixing point for the safety rope during the construction of the cap beam 1. The positioning bracket 31 can be formed by bending steel plate and using anchor nails. The upper part forms a ring that clamps the horizontal rope 3, and the lower part forms a base that is bolted to the cap beam 1. The base is reinforced with elbow plates on both sides. The clamping and fixing enhances the overall rigidity of the horizontal rope 3 and avoids sagging or swaying due to large span. The limiting ring groove 40 of the inner ring of the open ring 4 cooperates with the ball 41 to transform the sliding friction between the traditional hook and the safety rope into rolling friction, which greatly reduces the sliding resistance and makes the movement of the workers smoother. The design of the positioning bracket 31, which can pass through the opening of the open ring 4 and between the adjacent ball 41, realizes the continuous sliding of the hook along the horizontal rope 3, ensuring uninterrupted protection for the workers when the cap beam 1 moves in its entire range, and effectively reducing the risk of falling from height. The overall structure takes into account both the reliability of fixing and the convenience of movement, and is suitable for the special construction environment of the cap beam 1 without edge protection.

[0023] Furthermore, in specific implementation, such as Figure 7 As shown, the opening of the opening ring 4 provided in this embodiment of the present invention is an hourglass shape with a narrow middle and gradually widening ends along the axial direction, which has a clear guiding function. The structure with gradually widening ends can guide the alignment when the positioning bracket 31 approaches the opening, reducing the collision or misalignment between the positioning bracket 31 and the edge of the opening, so that the positioning bracket 31 can enter and exit the opening more smoothly, reducing the jamming phenomenon during the sliding process and improving the smoothness of operation. The structure with a narrow middle forms a certain constraint on the opening after the positioning bracket 31 passes through, preventing the opening from expanding excessively and affecting the overall stability.

[0024] Furthermore, in specific implementations, the diameter of the ball bearing 41 provided in this embodiment is larger than the opening width of the open ring 4. Specifically, the ball bearing 41 is in clearance fit with the limiting ring groove 40, and there is also a movable gap between the ball bearings 41, providing dynamic adjustment space. The design that the diameter of the ball bearing 41 is larger than the opening width constitutes a key safety constraint design, which can effectively prevent the ball bearing 41 from falling out of the opening of the open ring 4, ensuring that the ball bearing 41 is always confined within the limiting ring groove 40, avoiding failure of the rolling friction structure due to the ball bearing 41 falling, thereby causing the open ring 4 to jam or the safety rope to wear. This ensures reliable contact between the ball bearing 41 and the horizontal rope 3 (achieving the rolling friction function), and also provides space for the positioning bracket 31 to pass through through the natural gap between the ball bearings 41, thus taking into account both structural safety and functional feasibility.

[0025] Furthermore, in specific implementation, the angle between the line connecting the axes of the connecting ring 42 and the open ring 4 provided in this embodiment of the present invention and the central axis of the opening of the open ring 4 is an obtuse angle. Specifically, the connecting ring 42 is used to connect the safety rope. In actual construction scenarios, the horizontal rope 3 is set at approximately the thigh level of the worker, and the horizontal rope 3 is arranged on the center line of the width of the cap beam 1. The worker walks on one side of the horizontal rope 3 on the cap beam 1. On the one hand, this effectively avoids structural interference during use, ensuring that the force direction of the safety rope and the sliding direction of the open ring 4 form a reasonable angle. On the other hand, it reduces the interference and jamming of the safety rope by the opening of the open ring 4 and the positioning bracket 31 when the worker moves, reduces the need for alignment adjustment operations, and improves the smoothness of sliding.

[0026] Furthermore, in specific implementation, the horizontal rope 3 provided in this utility model embodiment is fixed by rope clamps 32 after passing over the pre-embedded buckles 2 at both ends, which enhances the connection strength between the horizontal rope 3 and the pre-embedded buckles 2. The operation is simple and meets the needs of rapid installation on the construction site. At the same time, it provides a reusable connection structure for the horizontal rope 3, which facilitates the reuse of materials.

[0027] Furthermore, in specific implementation, at least three rope clamps 32 are provided at the connection between the horizontal rope 3 and the pre-embedded buckle 2 provided in this embodiment of the utility model, and the clamping seats of all rope clamps 32 face the side of the longer rope segment of the horizontal rope 3. Specifically, the rope clamps 32 adopt existing technology and include three parts: a U-bolt, a clamping seat, and a nut. The U-bolt is U-shaped with threads at both ends and can pass through the corresponding through holes on the clamping seat; the clamping seat is a block structure with an arc-shaped groove on one side that matches the diameter of the horizontal rope 3 for fitting the surface of the horizontal rope 3. The setting of three or more rope clamps 32 disperses the tension of the horizontal rope 3 by applying force at multiple points, avoiding the overall connection breakage caused by the failure of a single rope clamp 32, and forming a redundant safety guarantee; the clamping seat facing the side of the longer rope segment conforms to the mechanical force principle of the rope clamp 32. When the horizontal rope 3 is under tension, the clamping seat can fit more tightly against the longer rope segment, enhance the friction between the rope clamp 32 and the rope, prevent the rope clamp 32 from loosening and slipping, and ensure long-term stable fixing effect.

[0028] Furthermore, in specific implementations, the axial distance between two adjacent rope clamps 32 provided in this embodiment of the invention is not less than six times the diameter of the horizontal rope 3. This ensures that the horizontal rope 3 transmits load evenly when under stress, avoiding localized stress concentration caused by excessively dense rope clamps 32, and reducing damage to the horizontal rope 3 caused by compression deformation. At the same time, sufficient spacing ensures that each rope clamp 32 can independently perform its fixing function, avoiding the problem of synergistic failure due to insufficient spacing, extending the service life of the horizontal rope 3, and improving the durability of safety protection.

[0029] Furthermore, in specific implementation, the pre-embedded buckle 2 provided in this utility model embodiment adopts U-shaped steel bars. The U-shaped structure provides a ring-shaped fixed support for the horizontal rope 3, stably constrains the position of the horizontal rope 3, and prevents the horizontal rope 3 from slipping when under force; the steel bar material has high strength and strong corrosion resistance, and after being pre-embedded in the stop block 11 of the cap beam 1, it can be firmly combined with the concrete structure, providing a long-term reliable load-bearing foundation.
