Description

Technical Field

[0001] This utility model relates to the field of bottle making machine production technology, and in particular to a roll device for laying underwater geomats in shallow water areas on land. Background Technology

[0002] In the field of hydraulic engineering construction, including ports and waterways, water conservancy projects, and ecological revetments, the laying of underwater geomats (such as geotextiles and gabion mats) is a fundamental and crucial process, mainly used for erosion control, filtration, foundation reinforcement, and ecological restoration. Currently, when carrying out such operations in shallow waters or tidal zones, common traditional construction methods mainly include direct manual laying and ship-positioned laying.

[0003] However, at present, these two construction methods have some significant drawbacks: manual laying is slow, preparation work for ship laying is complicated, and the effective working time is short due to the influence of water level. The whole process is cumbersome, and the connection between each link is not smooth, which seriously affects the construction progress.

[0004] In addition, underwater operations face risks such as drowning and cuts, and vessels operating in shallow waters are at risk of running aground. The complex on-site environment also brings many challenges to equipment and personnel management.

[0005] To address the aforementioned issues, we have developed a roll-type device that can be hoisted and laid on land for underwater geomats in shallow water areas. Utility Model Content

[0006] This utility model discloses a roll device for hoisting and laying underwater geomats in shallow water areas on land, aiming to solve the technical problems in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A roll-up device for hoisting and laying underwater geomats in shallow water areas on land includes: The roller is configured as a hollow tube, and both ends of the roller are fixedly connected to shaft-shaped mounting ends; The mounting end is provided with a bearing mounting position and a threaded connection position; The connecting end has a ball bearing installed inside, the ball bearing is sleeved on the bearing mounting position, and the connecting end has a mounting hole, in which a connecting rod is fixedly connected. The sling is fixedly connected at both ends to the end face of the corresponding connecting rod. Each threaded connection position is provided with a through hole; A fixing pin is movably inserted into the through hole.

[0008] In a preferred embodiment, the fixing pin has a through groove, and a baffle is provided on the top of the fixing pin; The outer side of the fixing pin is provided with a blocking slope, and the end of the fixing pin is provided with an installation slope.

[0009] In a preferred embodiment, the maximum diameter of the blocking bevel is greater than the diameter of the through hole, and the minimum diameter of the mounting bevel is less than the diameter of the through hole.

[0010] In a preferred embodiment, the maximum diameter of the mounting ramp is connected to the maximum diameter of the blocking ramp.

[0011] In a preferred embodiment, a lock nut is threaded onto the threaded connection position.

[0012] The roll device for hoisting and laying underwater geomats in shallow water areas provided by this utility model has the following advantages: This utility model, through the connection structure of rollers and slings, facilitates construction in conjunction with cranes and other machinery on the construction site, realizing the functions of direct hoisting on land and automatic unwinding and laying underwater. Through the double anti-loosening design of elastic fixing pins and locking nuts, it ensures long-term reliable locking under vibration environment. This not only ensures the convenience of installing geomats and greatly improves laying efficiency, but also significantly improves construction efficiency compared with traditional manual laying, while significantly reducing labor intensity and safety risks.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0019] This utility model discloses a roll device for hoisting and laying underwater geomats in shallow water areas on land.

[0020] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a roll-up device for hoisting and laying underwater geomats in shallow water areas on land includes: Roller 1 is a hollow tube, and both ends of roller 1 are fixedly connected to shaft-shaped mounting ends 2. The mounting end 2 is provided with a bearing mounting position 3 and a threaded connection position 4; Connecting end 5, a ball bearing 9 is installed inside the connecting end 5, the ball bearing 9 is sleeved on the bearing mounting position 3, the connecting end 5 has a mounting hole 6, and a connecting rod 7 is fixedly connected inside the mounting hole 6; The sling 8 has both ends fixedly connected to the end face of the corresponding connecting rod 7; Each threaded connection 4 is provided with a through hole 10; The fixing pin 12 is movably inserted into the through hole 10; In this embodiment: First, the rolled geomat is placed on the roller 1. During the hoisting and laying, the hook of the hoisting equipment is connected to the sling 8. The sling 8 transmits the lifting force to the connecting end 5 through the connecting rod 7. The connecting end 5 transmits the force to the installation end 2 through the internal ball bearing 9 and finally acts on the roller 1, thereby realizing the overall hoisting.

[0021] The ball bearing 9 allows the roller 1 to rotate freely relative to the connecting end 5 and the sling 8. When the device is hoisted above the laying area and moved, the geomat is pulled off the roll by manual or other forces. This pulling force drives the roller 1 to rotate, thereby reducing the unwinding resistance and realizing the smooth and continuous underwater laying of the geomat. This effectively avoids uneven laying or material damage caused by jamming or excessive resistance.

[0022] The fixing pin 12 is inserted into the through hole 10 as a physical limit to prevent the roller 1 from moving axially unexpectedly when it is not in operation or during transportation, thus ensuring the stability of the structure.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, the fixing pin 12 is provided with a through groove 13, and a baffle 16 is provided on the top of the fixing pin 12. A blocking slope 14 is provided on the outer side of the fixing pin 12, and an installation slope 15 is provided at the end of the fixing pin 12; In this embodiment: when inserted into the through hole 10, the mounting bevel 15 at its end first contacts the hole wall. Under pressure, the bevel guides and squeezes, causing the pin with the through groove 13 to undergo slight elastic contraction, thus smoothly entering the through hole 10. After the maximum diameter part of the blocking bevel 14 passes through, the pin recovers by its own elasticity. At this time, the blocking bevel 14 will be stuck on the inner edge of the through hole 10, forming an interlock to prevent the fixing pin 12 from accidentally falling off due to vibration. The baffle 16 at the top is larger than the through hole 10, which can prevent the fixing pin 12 from falling completely into the hole. It can also be used as a tapping point. During installation, the fixing pin 12 can be inserted into the through hole 10 by tapping the baffle 16.

[0024] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, the maximum diameter of the blocking slope 14 is greater than the diameter of the through hole 10, and the minimum diameter of the mounting slope 15 is smaller than the diameter of the through hole 10. In this embodiment, the minimum diameter of the mounting ramp 15 is smaller than the diameter of the through hole 10, ensuring that the end of the fixing pin 12 can be aligned and begin to enter the through hole 10, thus reducing the installation difficulty. The maximum diameter of the blocking ramp 14 is larger than the diameter of the through hole 10, forming an anti-dislodgement structure. Once the fixing pin 12 is installed in place, the "large diameter" part of its blocking ramp 14 will be stuck in the opening of the through hole 10, ensuring that the fixing pin 12 will not be shaken out when subjected to vibration or impact.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, the maximum diameter of the mounting ramp 15 is connected to the maximum diameter of the blocking ramp 14. In this embodiment, the maximum diameter of the mounting inclined surface 15 is connected to the maximum diameter of the blocking inclined surface 14, so that the outer contour of the fixing pin 12 forms a continuous surface, making the insertion process of the fixing pin 12 smoother and reducing friction and jamming during insertion. At the same time, this connection method also ensures a continuous and rapid functional transition from "easy to insert" to "forming a barrier". Furthermore, when it is necessary to remove the fixing pin 12, it can be disengaged by tapping the fixing pin 12 in the opposite direction.

[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, a locking nut 11 is threaded onto the threaded connection 4; In this embodiment, the locking nut 11 is tightened onto the threaded connection 4 to press and fix the inner ring of the ball bearing 9 axially, ensuring that the bearing will not have axial play when the roller 1 rotates, making the rotation of the roller 1 more stable. At the same time, it works together with the fixing pin 12 to form a double anti-loosening mechanism, preventing the nut from loosening under long-term vibration environment and improving the safety of the entire device in dynamic working environment.

[0027] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
