Description

Technical Field

[0001] This utility model relates to the field of hydrological emergency response, and in particular to a rope winding and fixing auxiliary device for hydrological emergency flow measurement. Background Technology

[0002] When conducting emergency river hydrological measurements on bridges, traditional methods rely primarily on operators leaning over the railing to manually reel in and out the ropes attached to the current meter. This method not only exposes operators to significant safety risks of falls from heights but is also physically demanding and inefficient. Especially during measurement breaks or when temporary fixation is required, the rope is typically wrapped or knotted to the railing; this method is cumbersome and unreliable, posing a risk of the expensive current meter falling and being damaged due to rope loosening or slippage. Currently, there is a lack of dedicated auxiliary devices that integrate rapid fixation, reliable locking, labor-saving reeling in and out, and effective guidance, making it difficult to meet the urgent needs of emergency river hydrological measurements for safety, efficiency, and reliability.

To this end, this invention proposes a rope winding and fixing auxiliary device for hydrological emergency flow measurement. Through integrated design, it integrates fixing, guiding, winding and clamping functions into one unit, significantly improving the safety, reliability and work efficiency of hydrological emergency flow measurement operations.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A rope winding and securing auxiliary device for emergency hydrological flow measurement, including The fixing unit includes a fixing bracket. The bottom of the fixing bracket is provided with a slot for engaging the railing. The side of the fixing bracket is provided with at least one horizontal locking bolt. By tightening the horizontal locking bolt, the end of the bolt is pressed against the upright of the railing, thereby fixing the entire device to the bridge railing. The guiding unit includes a guide rod fixed to the front end of the fixed bracket. The guide rod has a guide groove along its length for accommodating and guiding the flow measurement rope. A roller is provided at the front end outlet of the guide groove. The winding unit includes a winding motor and a winding wheel installed at the rear end of the fixed bracket. The winding motor drives the winding wheel to rotate for winding and unwinding the flow measuring rope. The rope clamping unit includes a hydraulic cylinder that provides the fixed bracket and clamping blocks that are provided on both sides of the guide groove. The hydraulic cylinder drives the clamping blocks to clamp or release the flow measurement rope.

[0005] According to an embodiment of this utility model, a rope winding and fixing auxiliary device for emergency hydrological flow measurement has at least the following beneficial effects: Through integrated design, fixing, guiding, winding, and clamping functions are combined into one unit, significantly improving the safety, reliability, and efficiency of emergency hydrological flow measurement operations. The fixing unit, utilizing the cooperation of slots and horizontal locking bolts, can quickly and securely install the device on bridge railings, effectively avoiding the risk of falls from heights caused by personnel needing to lean over the bridge in traditional operations. The guide groove and front roller in the guiding unit ensure smooth and directional movement of the flow measurement rope during winding and unwinding, greatly reducing rope wear and jamming. The rope clamping unit, using a hydraulic drive, can generate strong clamping force, achieving instantaneous and reliable locking of the rope and preventing accidental falls of the current meter. The winding unit, driven by a motor, achieves mechanization and labor-saving of rope winding and unwinding, significantly reducing the labor intensity of operators. This device has a compact structure and is easy to operate, making it particularly suitable for complex working conditions such as emergency flow measurement in the field, providing strong support for hydrological monitoring work.

[0006] According to some embodiments of the present invention, one end of the horizontal locking bolt located in the slot is connected to an anti-slip pad.

[0007] The benefits are that the anti-slip pads increase the friction between the locking end and the railing post, making the device more secure and reliable. At the same time, they prevent the metal bolts from directly tightening and causing scratches or damage to the railing surface, thus providing good protection.

[0008] According to some embodiments of the present invention, an operating handwheel is connected to one end of the horizontal locking bolt located outside the slot.

[0009] The advantages are: the handwheel can be easily turned by hand, and the installation and fastening of the device can be completed without the need for additional tools, which simplifies the operation steps and improves the convenience and efficiency of field operations.

[0010] According to some embodiments of the present invention, the inner wall of the guide groove of the guide rod is a smooth arc-shaped surface.

[0011] The advantages are: the smooth, curved inner wall provides a smooth sliding channel for the rope, which can effectively reduce the frictional resistance and wear of the rope during the guiding process, extend the service life of the rope, and ensure the smoothness of the retrieval and deployment operations.

[0012] According to some embodiments of the present invention, the rim of the roller has a V-shaped or U-shaped groove structure.

[0013] The advantages are that the V-shaped or U-shaped groove structure can provide good radial constraint on the rope, preventing the rope from shifting laterally or derailing on the roller, ensuring the accuracy and reliability of guidance, and improving operational safety.

[0014] According to some embodiments of the present invention, the rope clamping unit further includes an operating handle, which is connected to the hydraulic cylinder, and power is provided to the hydraulic cylinder by moving the operating handle.

[0015] The advantages are: the operating handle provides an intuitive and labor-saving manual driving method. The operator can generate huge hydraulic clamping force by simply turning the handle, realizing the rapid locking and releasing of the rope. The operation is simple and highly reliable.

[0016] According to some embodiments of the present invention, the hydraulic cylinder is provided with a pressure relief valve for releasing the pressure of the hydraulic cylinder to loosen the clamping block.

[0017] The advantages are: the pressure relief valve makes it easy and quick to release the clamping state; the rope can be released with a single button press, which greatly improves the convenience of operation and is conducive to frequent start-stop operations.

[0018] According to some embodiments of this utility model, the winding motor is a worm gear reducer motor with a self-locking function.

[0019] The advantage is that the worm gear transmission mechanism has a natural self-locking characteristic, which can automatically prevent the winding wheel from reversing when the motor is powered off, providing another safety barrier for the flow meter, preventing it from sliding down due to its own weight, and enhancing the safety of the system.

[0020] According to some embodiments of the present invention, the surface of the winding wheel is provided with anti-slip texture.

[0021] The benefits are that the anti-slip texture increases the contact friction between the winding wheel and the rope, effectively preventing slippage between the rope and the wheel surface during winding and unwinding, and ensuring transmission efficiency and control precision.

[0022] According to some embodiments of the present invention, the fixed bracket is further provided with a safety ring hole for connecting an auxiliary safety rope.

[0023] The advantage is that the safety ring hole provides an interface for connecting the auxiliary safety rope, allowing the device to be secondary secured to other stable parts of the railing via an additional rope, forming redundant safety protection and further enhancing the safety level of the entire flow measurement system.

[0024] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The following is for reference. Figures 1-4 A rope winding and securing auxiliary device for emergency hydrological flow measurement is described in detail with reference to a specific embodiment. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.

[0033] like Figures 1-4 As shown, the rope winding and fixing auxiliary device for hydrological emergency flow measurement mainly consists of four functional units. The core component of the fixing unit is a fixing bracket 100. The bottom of the bracket is machined with a slot 110 for engaging the bridge railing, and at least one horizontal locking bolt 120 is installed on the side of the bracket. After the device is initially placed on the railing through the slot 110, the horizontal locking bolt 120 is tightened to firmly press its end against the railing post, thereby achieving a quick and stable installation of the entire device on the bridge railing. To improve the reliability of the fixing and protect the surface of the railing, an anti-slip pad 210 can be installed at the end of the horizontal locking bolt 120 that is pressed against the railing, and a handwheel that is easy to operate by hand can be configured at its outer end, making the installation process more convenient without additional tools.

[0034] like Figure 2 and Figure 3 As shown, the guiding unit includes a guide rod 130 fixedly mounted at the front end of the fixed bracket 100. The guide rod 130 has a guide groove 150 along its length specifically for accommodating and guiding the flow measurement rope 140. To ensure smooth rope movement and reduce wear, the inner wall of the guide groove 150 can be machined into a smooth arc-shaped surface. At the front outlet of the guide groove 150, a roller 160 is installed. The rim of the roller 160 preferably adopts a V-shaped or U-shaped groove structure, which can effectively restrain the rope and prevent it from lateral displacement or derailment during use, ensuring the accuracy and reliability of the guidance.

[0035] like Figure 4As shown, the rope clamping unit is integrated on the fixed bracket 100. Its core consists of a hydraulic cylinder 190 and a pair of clamping blocks 200 positioned on either side of the guide groove 150. The hydraulic cylinder 190 is driven by an operator via an operating handle 230. Moving the handle provides power to the hydraulic cylinder 190, driving the two clamping blocks 200 to move towards each other, generating a powerful clamping force to firmly lock the rope. The hydraulic cylinder 190 is also equipped with a pressure relief valve 240. When it is necessary to loosen the rope, opening the pressure relief valve 240 instantly releases the pressure, causing the clamping blocks 200 to separate, making operation very convenient. This hydraulic clamping method achieves instantaneous and reliable locking of the rope.

[0036] like Figure 2 As shown, the winding unit includes a winding motor 170 and a winding reel 180, which are mounted at the rear end of the fixed bracket 100. The winding motor 170 is preferably a worm gear reducer motor with a self-locking function. When the motor stops working, its self-locking characteristic automatically prevents the winding reel 180 from reversing, providing additional safety protection for the flow meter. The motor drives the winding reel 180 to rotate, thereby realizing the mechanized winding and unwinding of the flow measuring rope 140, greatly reducing the physical exertion of the operator. To further prevent rope slippage, the surface of the winding reel 180 can be machined with anti-slip textures to increase friction and ensure accurate and reliable transmission. In addition, a safety ring hole 250 can be provided on the fixed bracket 100 for connecting an auxiliary safety rope, providing secondary fixation to other parts of the railing and forming redundant safety protection.

[0037] During operation, the operator first places the device in a suitable position on the railing via the slot 110, and then rotates the handwheel to secure the anti-slip pad 210 firmly against the upright post for initial fixation. Next, the rope with the flow meter attached is passed through the guide horn and runs along the polished guide groove 150, around the V-shaped roller 160. During lowering, the rope moves smoothly within the mirror groove, and the hydraulic clamp, controlled by the handle, allows for precise suspension at any position. After measurement, the winding motor 170 is started, and the rope is systematically wound and retrieved onto the anti-slip textured winding wheel 180. The entire operation is fully mechanized, eliminating the need for personnel to extend beyond the railing. The overall benefits are significant in three aspects: safety – completely eliminating the risks of working at heights, with multiple safety mechanisms ensuring equipment safety; reliability – each unit is precisely designed and rigorously tested to ensure stable operation in harsh environments; and efficiency – mechanized operation significantly reduces the time required for a single operation, making it particularly suitable for emergency monitoring tasks. The device has a reasonable structural layout and is easy to maintain. Through integrated design, it combines fixing, guiding, winding and clamping functions into one, which significantly improves the safety, reliability and efficiency of hydrological emergency flow measurement operations.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
