Description

Technical Field

[0001] This utility model relates to the field of dredging hose technology, and specifically to dredging hose connectors. Background Technology

[0002] Dredging hoses are key pieces of equipment used in dredging projects. They are mainly used for connecting dredgers' discharge pipes in harbors, rivers, lakes, and other water bodies. They reduce swaying caused by waves, allowing for smoother flow of media within the pipe. Their core function is to reduce wave-induced swaying through a flanged structure and a large-diameter steel wire skeleton design, ensuring the smooth transmission of media such as silt and mud within the pipe.

[0003] A dredging hose connector, disclosed in CN223242343U, relates to the field of dredging pipe connection technology. It includes a dredging hose with a connecting flange and a mating flange at both ends, and a connecting bolt between the connecting flange and the mating flange. A connecting assembly is provided on the outside of the connecting flange and the mating flange. This utility model achieves reconnection and protection at the connection between the connecting flange and the mating flange through the connecting assembly. Two connecting clamps are secured to the outside of the connecting flange and the mating flange for protection. A sealing strip inserted into the connecting groove and an arc-shaped sealing strip inserted into the sealing groove improve the sealing effect between the two connecting clamps, reduce the corrosion of the connecting bolt by seawater or rainwater, extend the service life of the mating flange, connecting flange, and connecting bolt, and reduce the occurrence of media leakage.

[0004] The existing technology has the following shortcomings: When connecting dredging pipes, the existing connectors cannot be easily adjusted according to the thickness of the flanges at both ends of the dredging pipes. At the same time, the sealing effect at the connection point of the two dredging pipes is poor and the connection is not firm, which makes it easy for leakage to occur at the connection point of the two dredging pipes. As a result, the connection between the two dredging pipes is prone to loosening and falling off after long-term operation. Utility Model Content

[0005] The purpose of this utility model is to provide a dredging hose connector that can connect two dredging pipe bodies through a fixed sleeve plate and a movable sleeve plate. The limiting plate can clamp and limit the dredging pipe body under the elastic force of the traction spring and the connection action of the fastening bolt, so that the two dredging pipe bodies can be tightly connected, thereby solving the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dredging hose connector, including a dredging pipe body, and further comprising: The connecting mechanism is located on the outside of the connection position of the two dredging pipe bodies, and the four limiting mechanisms are located on the outside of both ends of the connecting mechanism. The connecting mechanism includes a fixed sleeve plate, which is movably sleeved on the outside of the connection position of the two dredging pipe bodies. A movable sleeve plate is rotatably installed on one side of the top of the fixed sleeve plate. A partition plate is fixedly installed on the inner side of both the fixed sleeve plate and the movable sleeve plate.

The limiting mechanism includes two traction springs, one end of each traction spring is provided with a limiting plate, and a fastening bolt is threaded into the inner wall of the limiting plate. The fastening bolt passes through the inner wall of the outer flange of the dredging pipe body and is threadedly connected to the inner wall of the adjacent partition plate.

[0007] Preferably, the limiting mechanism includes two mounting slots, and four sets of mounting slots are respectively opened at the inner ends of the fixed sleeve plate and the movable sleeve plate, and one end of the inner wall of the mounting slot is fixedly connected to one end of the adjacent traction spring.

[0008] Preferably, two movable seats are fixedly installed on the outer side of the limiting plate, and the two movable seats are respectively fixedly connected to the end of the adjacent traction spring away from the inner wall of the mounting groove, and a limiting rod is fixedly installed on the inner wall of the mounting groove.

[0009] Preferably, the outer wall of the limiting rod is slidably connected to the inner wall of the adjacent movable seat, the outer wall of the movable seat is slidably connected to the inner wall of the adjacent mounting groove, and the limiting rod is movably inserted into the inner side of the adjacent traction spring.

[0010] Preferably, the inner walls of the two limiting plates at the same end are provided with six fixing holes at equal intervals, and the inner walls of the two partition plates are provided with six mounting holes at equal intervals, with the fixing holes and mounting holes aligned.

[0021] This utility model provides, for example Figure 1 The dredging hose connector shown includes a dredging hose body 1, and also includes: The connecting mechanism 2 is located on the outside of the connection position of the two dredging pipe bodies 1, and the four limiting mechanisms 3 are located on the outside of both ends of the connecting mechanism 2.

[0022] To facilitate the splicing of the two dredging pipe bodies 1, such as Figure 1-5 As shown, the connecting mechanism 2 includes a fixed sleeve 201, which is movably sleeved on the outside of the connection position of the two dredging pipe bodies 1. A movable sleeve 202 is rotatably installed on one side of the top of the fixed sleeve 201. A partition plate 204 is fixedly installed on the inner side of both the fixed sleeve 201 and the movable sleeve 202. The two partition plates 204 are respectively set at the top and bottom of the inner side of the connection position of the two dredging pipe bodies 1. Two connecting bolts 203 are threaded into the inner wall of one side of the movable sleeve 202. The bottom of the two connecting bolts 203 is threaded to the inner wall of the fixed sleeve 201. By sleeved onto the outside of the flanges at the ports of the two dredging pipe bodies 1 through the fixed sleeve 201 and the movable sleeve 202, the two partition plates 204 can be positioned between the two dredging pipe bodies 1, which can achieve a sealing effect. The connecting bolts 203 penetrate the movable sleeve 202 and are threaded to the inner wall of the fixed sleeve 201, so that the two dredging pipe bodies 1 can be stably connected.

[0023] To enable the device to accommodate different thicknesses of the flange at port 1 of the dredging pipe body, such as Figure 1-3 and Figure 5 As shown, the limiting mechanism 3 includes two traction springs 302. A limiting plate 305 is provided at one end of each traction spring 302. A fastening bolt 307 is threaded into the inner wall of the limiting plate 305. The fastening bolt 307 passes through the inner wall of the outer flange of the dredging pipe body 1 and is threadedly connected to the inner wall of the adjacent partition plate 204. The inner diameter of the partition plate 204 is the same as the inner diameter of the dredging pipe body 1, and the inner diameter of the limiting plate 305 is the same as the outer diameter of the dredging pipe body 1. When connecting the dredging pipe body 1, its port flange is inserted between the partition plate 204 and the limiting plate 305. At the gap, the limiting plate 305 can be pushed to move towards both ends, causing the traction spring 302 to extend. Then, after the dredging pipe body 1 is connected, the limiting plate 305 is reset under the elastic force of the traction spring 302, which can clamp the port flange of the dredging pipe body 1. Then, the fastening bolt 307 is used to pass through the limiting plate 305 and the port flange and is threaded to the inner wall of the partition plate 204, so that the connector can adapt to the different thicknesses of the port flange of the dredging pipe body 1. Through the limitation of the limiting plate 305, the connection between the two dredging pipe bodies 1 is more firm and tight.

[0024] To ensure the stability of the limiting plate 305 during adjustment, such as Figure 2-3 and Figure 5 As shown, the limiting mechanism 3 includes two mounting slots 301. Four sets of mounting slots 301 are respectively opened at both ends of the inner side of the fixed sleeve plate 201 and the movable sleeve plate 202. One end of the inner wall of the mounting slot 301 is fixedly connected to one end of the adjacent traction spring 302. Two movable seats 303 are fixedly installed on the outer side of the limiting plate 305. The two movable seats 303 are respectively fixedly connected to the ends of the adjacent traction springs 302 away from the inner wall of the mounting slot 301. A limiting rod 304 is fixedly installed on the inner wall of the mounting slot 301. The outer wall of the limiting rod 304 is slidably connected to the inner wall of the adjacent movable seat 303. The outer wall of the movable seat 303 is slidably connected to the inner wall of the adjacent mounting groove 301. The limiting rod 304 is movably inserted into the inner side of the adjacent traction spring 302. The mounting groove 301 can install and fix the traction spring 302 and the limiting rod 304. The limiting plate 305 can move along the inner wall of the adjacent mounting groove 301 and the outer wall of the limiting rod 304 through the movable seat 303, so that it remains stable during the movement and can prevent it from detaching from the inner wall of the mounting groove 301. Thus, the limiting plate 305 can stably clamp the port flange of the dredging pipe body 1 of different thicknesses.

[0025] To ensure a tight connection between the limiting plate 305 and the port flange of the dredging pipe body 1, such as Figure 2-5 As shown, six fixing holes 306 are equally spaced on the inner walls of the two limiting plates 305 at the same end, and six mounting holes 205 are equally spaced on the inner walls of the two partition plates 204. The fixing holes 306 are aligned with the mounting holes 205. The inner wall of the fixing hole 306 is threaded to the outer wall of the adjacent fastening bolt 307. The end of the fastening bolt 307 away from the fixing hole 306 is threaded to the inner wall of the adjacent mounting hole 205. The fastening bolt 307 passes through the fixing hole 306 and the port flange of the dredging pipe body 1 and is threaded to the inner wall of the adjacent mounting hole 205. This allows the limiting plate 305 to stably clamp and limit the dredging pipe body 1, preventing the dredging pipe body 1 from detaching from the inside of the connector.

[0026] When connecting two dredging pipe bodies 1, the fixing sleeve 201 is fitted onto the outside of the port flanges of the two dredging pipe bodies 1, so that the partition plate 204 can be inserted into the gap between the two dredging pipe bodies 1. As the fixing sleeve 201 is fitted, the port flange of the dredging pipe body 1 will press against the limiting plate 305 at the same end, causing it to move along the inner wall of the adjacent mounting groove 301 outside the limiting rod 304 via the two movable seats 303, thereby causing the traction spring 302 to extend. After the fixing sleeve 201 is fully fitted onto the outer wall of one side of the port flange, the movable sleeve 202 is rotated so that it can be fitted onto the outer wall of the other side of the two port flanges. Similarly, the limiting plates 305 at both ends of the movable sleeve 202 move towards both ends. Then, by rotating the fixing sleeve 201 and the movable sleeve 202, the through hole in the inner wall of the port flange can be aligned with the mounting hole 205 and the fixing hole 306, and then... The connecting bolt 203 passes through the movable sleeve plate 202 and is threaded to the inner wall of the fixed sleeve plate 201, so that the fixed sleeve plate 201 and the movable sleeve plate 202 can be tightly fitted onto the outer side of the port flange of the two dredging pipe bodies 1. At the same time, after the fixed sleeve plate 201 and the movable sleeve plate 202 are fully fitted, the limiting plate 305 is reset under the elastic force of the traction spring 302, so that the two limiting plates 305 at the same end can clamp the port flange of the adjacent dredging pipe body 1. Then, the fastening bolt 307 is threaded into the inner wall of the fixing hole 306, so that it passes through the port flange and is threaded to the inner wall of the adjacent mounting hole 205, so that the limiting plate 305 can stably clamp and limit the port flange of the dredging pipe body 1, thereby allowing the connector to stably connect the two dredging pipe bodies 1. This embodiment specifically solves the problem that the connector in the prior art cannot adapt to the port flanges of different thicknesses of the dredging pipe.

[0027] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
