Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a quick-assembly and disassembly safety cable device. Background Technology

[0002] After the formwork and scaffolding of the bridge cap beam are removed, there are no suitable facilities or locations to fasten safety belts. During subsequent high-altitude operations such as concrete curing on the pier top and measurement and setting out of the bearing pad stones, there is a risk of falling from height. Therefore, it is necessary to install a safety cable device on the top surface of the cap beam to facilitate the fastening of safety belts and avoid injury or death accidents.

[0003] Existing patents CN213391306U and CN210216167U disclose "a safety rope suspension device for a cap beam and its suspension structure" and "a simple safety protection main rope device for a cap beam." These devices use U-shaped groove plates to fix the safety rope; however, the safety rope is positioned too low, and the tensile arm at the fixing point is too short, failing to meet the requirements of "high hanging, low use" and the necessary tensile strength. Furthermore, in patent CN220433431U, a clamping hook-shaped vertical rod and a clamp formed by the vertical rod are used to hold the seismic blocking block to improve the stability of the protective device. However, when the cap beam is long, the safety rope may sag due to the excessive distance between the fulcrums, thus affecting its effectiveness. Simultaneously, this device still suffers from insufficient inherent stability and a short tensile arm at the fixing point. Utility Model Content

[0004] To overcome the shortcomings of the prior art, a quick-release safety main rope device is provided.

[0005] The technical solution of this utility model is as follows: a quick-assembly and disassembly safety main cable device includes inner and outer steel sections, vertical poles, and stops assembled at both ends of a cap beam; tie rods for fixing the stops are assembled between the inner and outer steel sections; the vertical poles are assembled on the outer steel section, and a safety main cable is assembled between the two vertical poles. This device offers greater safety and stability, as the tie rods fix the stops between the inner and outer steel sections, forming a stable support structure; it also has strong adaptability, as the dimensions and positions of the components such as the inner and outer steel sections, vertical poles, and stops can be adjusted to flexibly meet various operational needs.

[0006] Preferably, both the inner and outer steel sections have multiple bolt holes on both sides that engage with the tie rods. These bolt holes allow for flexible adjustment of the tie rod's position, facilitating adjustments based on the position and height of the stop blocks. This rapid adjustment capability enables the device to adapt to different operating environments and requirements, enhancing its flexibility and adaptability.

[0007] Preferably, the top of the vertical pole is provided with a ring bolt for the safety cable to pass through.

[0008] Preferably, the vertical pole is equipped with a rope tightening device for tightening both ends of the safety main rope.

[0009] Preferably, the rope tightening device includes a rope tightener and a base bolt; the rope tightener is fixed to the vertical pole by the base bolt.

[0010] Preferably, a fixing frame structure is assembled between the vertical post and the stop block. The fixing frame structure ensures a secure connection between the stop block and the vertical post, preventing the stop block from moving or falling off under load. The reinforcement provided by the fixing frame structure reduces wear and damage between the stop block and the vertical post, helping to extend the service life of the entire device and improving its economy and practicality.

[0011] Preferably, the fixed frame structure includes inverted angle steel, horizontal angle steel and vertical angle steel; the inverted angle steel is assembled on the top side of the stop block near the vertical upright, and the horizontal angle steel and vertical angle steel are connected to the inverted angle steel.

[0012] Preferably, diagonal bracing is installed between the vertical uprights and the fixed frame structure.

[0013] Preferably, a crossbar is attached to the side of the outer steel section near the tie rod.

[0014] Preferably, one end of the diagonal brace is fitted at the connection between the horizontal and vertical angle steels, and the other end is fitted in the middle of the vertical pole.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Easy and quick assembly and disassembly: The positions and spacing of the inner and outer steel sections and the tie rods of this utility model are pre-adjusted on the ground according to the width of the cap beam. During installation, simply insert the stop blocks and tighten the tie rods to secure them firmly. During disassembly, simply loosen the tensioner and then loosen the tie rods.

[0017] 2. The structure is stable and reliable. In this utility model, the vertical pole is fixed at the lower end of the stop block, while the force is applied at the upper end of the stop block. The tensile arm is relatively long, and the contact area between the vertical pole and the stop block is increased by using inverted angle steel, preventing the safety cable from tilting left and right under tension, thus making the force distribution more reasonable and stable. At the same time, the pole is equipped with diagonal bracing and its fixing frame structure, which can resist part of the tensile force on the vertical pole, making the vertical pole stable and the force distribution more reliable.

[0018] 3. The function is effectively guaranteed. The height of the vertical poles meets the requirements of the specifications, and the safety main rope is tightened by the rope tensioner to ensure the height of the safety main rope, prevent the middle part from sagging, and ensure the safety function of the safety main rope as required by the specifications. At the same time, during installation and dismantling, this utility model can be operated on the top surface of the cap beam without going beyond the cap beam area, making the operation safe.

[0019] 4. Wide range of applications: This utility model has multiple sets of bolt holes on the inner and outer steel sections. By inserting tie rods into different bolt holes, it can adapt to cap beams of different widths. It can also change the position of the safety cable on the axis of the cap beam. By selecting tie rods of different lengths, it can adapt to blocks of different thicknesses.

[0020] Other features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description
