Description

Technical Field

[0001] This utility model relates to cable conveying equipment in marine engineering, and more particularly to a device for quick disassembly and convenient replacement of cables for towing. Background Technology

[0002] Various types of cable towing devices exist in marine engineering construction. These devices are not only numerous but also frequently used in marine module construction. Traditional cable trolleys are mostly integrally welded or bolted structures. When parts of the trolley (such as rollers or tracks) are damaged or need to be replaced, the entire trolley must be removed from the track, making the repair and replacement process cumbersome, requiring tools and time-consuming. After long-term use, the trolleys are prone to rust and wear, resulting in high costs for overall replacement or maintenance, and significant downtime. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a quick-release cable trolley with a reasonable structure, convenient assembly and disassembly, easy maintenance and flexible adaptation to different cable layout requirements.

[0004] This utility model discloses a quick disassembly and convenient replacement device for cable dragging, comprising an upper suspension module and a lower slide rail module;

[0005] The upper suspension module includes a main frame, which is a channel steel structure. A set of traveling wheels is rotatably connected to the inner walls of the front and rear flanges of the main frame via axles. The two sets of traveling wheels are supported on the front and rear sides of the lower flange of the I-beam track and can roll along the lower flange, allowing the upper suspension module to move left and right along the I-beam track. The lower slide module includes an arc-shaped main cable slide, on which a T-shaped block is connected. The T-shaped block has two legs spaced apart on the left and right sides. The two legs are welded to the top wall of the arc-shaped main cable slide. A pressure plate is installed on the arc-shaped main cable slide between the two legs. The pressure plate is connected to the arc-shaped main cable slide by bolts and nuts. A U-shaped opening groove is welded to the bottom wall of the web of the main frame. A long groove is cut in the middle of the web of the U-shaped opening groove, which is horizontally oriented. The horizontal plate of the T-shaped block is supported on the top wall of the web of the main frame and located between the two sets of traveling wheels. The two legs are located at the long groove.

[0006] Advantages of this invention: Modular quick-release design, dividing the trolley into two independent modules connected by a quick-release mechanism, achieves separation of the upper suspension part and the lower functional part, greatly facilitating installation, disassembly, and subsequent maintenance and component replacement. Highly efficient maintenance and reduced costs: When the cable trolley is partially damaged or the cable load configuration needs to be changed, only the corresponding lower slide rail module needs to be replaced, without disassembling the entire trolley system, significantly reducing maintenance time and costs. High flexibility: By replacing different models of lower slide rail modules, it can quickly adapt to different cable laying requirements such as single-rail and double-rail systems, improving the equipment's versatility and adaptability. High reliability: The quick-connect mechanism is designed with a locking function, ensuring the stability and safety of the trolley during operation and preventing accidental detachment.

[0011] The present invention will now be described in detail with reference to the accompanying drawings and specific examples.

[0012] As shown in the attached figure, this utility model provides a quick disassembly and convenient replacement device for cable dragging, including an upper suspension module 1 and a lower slide module 2.

[0013] The upper suspension module 1 and the lower slide rail module 2 can be designed as a single-cable slide rail type or a double-cable slide rail type, depending on the number and method of the carrying cables (e.g., Figure 3 (As shown).

[0014] The upper suspension module 1 includes a main frame 1-1, which is a channel steel structure. A set of traveling wheels 1-2 is rotatably connected to the inner walls of the front and rear flanges of the main frame 1-1 via axles. Each set of traveling wheels includes two wheels, which are supported on the front and rear sides of the lower flange of the I-beam track 3 and can roll along the lower flange, allowing the upper suspension module 1 to move left and right along the I-beam track 3. The I-beam track can be an existing cable tray on site.

[0015] The lower slide module 2 includes an arc-shaped main cable slide 2-2, on which a T-shaped block 2-1 is installed. The T-shaped block has two legs spaced apart on the left and right sides, which are welded to the top wall of the arc-shaped main cable slide. A pressure plate 2-4 is installed on the arc-shaped main cable slide between the two legs, and the pressure plate is connected to the arc-shaped main cable slide by bolts and nuts. A U-shaped opening groove 1-3 is welded to the bottom wall of the web of the main frame. A long groove is cut in the middle of the web of the U-shaped opening groove 1-3, which is horizontally oriented. The horizontal plate of the T-shaped block is supported on the top wall of the web of the main frame and located between two sets of traveling wheels. The two legs are located at the long groove.

[0016] Preferably, a first pin hole 2-3 is welded to the bottom wall of the horizontal plate of the T-shaped block between the two legs. The first pin hole is located at a position corresponding to the long groove. Second pin holes 4-2 are welded to the bottom wall of the web plate of the U-shaped open slide groove on both sides of the long groove. The first pin hole and the two second pin holes are connected by an anti-detachment cotter pin 4-1. This prevents the upper suspension module 1 and the lower slide module 2 from accidentally separating due to vibration or other reasons.

[0017] The working principle is as follows:

[0018] When in use, the cable is clamped and fixed to the main cable slide rail 2-2 by the clamping plate 2-4. The device moves the cable by sliding along the I-beam rail 3 via the traveling wheel set 1-2. When a cable trolley needs maintenance or a change of slide rail type, the operator does not need to remove the entire trolley. Simply pull out the anti-detachment cotter pin 4-1 from the first pin hole and the two second pin holes, and the T-block 2-1 can be removed along the U-shaped opening slide groove 1-3. This allows the damaged or replacement lower slide rail module 2 to be removed and replaced with a new, functional or different type module. Then, the anti-detachment cotter pin 4-1 is inserted into the symmetrical pin holes 4-2, and the two feet of the cotter pin are bent to fix the new lower slide rail module 2. The entire process can be completed in a few minutes, greatly improving work efficiency.
