Technical Field

[0001] The utility model relates to the technical field of port pipeline protection, in particular to a port pipeline protection device. Background Art

[0002] Ports are the gathering points and hubs of water and land transportation, the distribution centers of industrial and agricultural products and foreign trade import and export materials, and the places where ships anchor, load and unload cargo, pick up and drop off passengers, and replenish supplies. Therefore, ports have a large number of mechanical equipment for handling and lifting cargo, and the operation of the equipment requires the use of electricity, gasoline or diesel. Therefore, in order to facilitate adjustments, pipelines will be laid on the port ground and properly protected.

[0003] After searching

[0004] A pipeline protection device for a port, with the publication number CN219692629U. When in use, a first protection body and a second protection body can be placed on both sides of the pipeline respectively, and then the second protection body can be pushed toward the first protection body, so that the pipeline can be slowly lifted up by using a plurality of positioning trustee splines, so that the pipeline can be positioned in the accommodating cavity and thus be separated from the ground. After the plurality of positioning trustee splines are inserted into the corresponding positioning slots, the preliminary combination positioning between the first protection body and the second protection body can be achieved. After the combination, a plurality of top connecting blocks can be inserted into the corresponding top connecting grooves. At this time, a plurality of top fixing bolts can be used to fix the installation positions of the plurality of top connecting blocks. At the same time, the two bottom connecting blocks will be inserted into the corresponding bottom connecting grooves. At this time, the two bottom fixing bolts can be used to fix the bottom between the first protection body and the second protection body.

[0005] However, during the pipeline laying process, a connecting port is used to connect two sections of the pipeline to extend the laying length of the pipeline. When the first protective body and the second protective body are installed along the pipeline laying route, the use of longer first protective body and second protective body is prone to cause the longer first protective body and second protective body to be removed when connecting at the maintenance interface, resulting in the longer pipeline being unable to be protected, which can easily cause the pipeline to be damaged by being crushed by vehicles. When the shorter first protective body and second protective body are used, they need to be manually spliced ​​one by one during laying, resulting in different forces acting on the spliced ​​first protective body and the second protective body, and because there is no connection mechanism on the contact surface at the splicing point, they will offset from each other when subjected to different forces or vibrations, affecting the protection of the pipeline.

[0023] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0024] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0025] Such as Figures 1-5As shown in the figure, a pipeline protection device for a port includes a number of protection bodies 1 with cavities formed inside. The length and orientation of the protection bodies 1 are set according to the length and orientation of the pipeline itself. A joint maintenance pad 2 for installation at the pipeline joint is inserted between two adjacent protection bodies 1. The joint maintenance pad 2 is installed at the connection of the two ends of the pipeline. When maintaining the pipeline joint, only the joint maintenance pad 2 needs to be taken out:

[0026] At the position of the side of the joint maintenance pad 2 corresponding to the cavity of the protection body 1, a clamping groove 17 is formed. A plug post 7 for inserting into the cavity of the protection body 1 is slidably connected in the clamping groove 17. By inserting the plug post 7 into the cavity, the offset and dislocation between the joint maintenance pad 2 and the protection body 1 can be prevented. A countersunk nut 6 is embedded on the side of the protection body 1. An installation groove 9 is formed on the side of the joint maintenance pad 2. A cover plate 3 is embedded and slidably connected at the notch of the installation groove 9 on the surface of the joint maintenance pad 2. The arranged cover plate 3 can prevent rainwater and dust from entering the installation groove 9 under normal circumstances. A screw rod 5 with the same height as the countersunk nut 6 is penetrated through the wall of the installation groove 9. The position where the countersunk nut 6 is installed in the protection body 1 is penetrated, and the penetration part is in clearance fit with the screw rod 5, so that the screw rod 5 can enter the protection body 1. The center line of the countersunk nut 6 is penetrated and threadedly connected with the screw rod 5. When the joint maintenance pad 2 is installed between two protection bodies 1, by rotating the screw rod 5 in the installation groove 9, due to the threaded connection between the screw rod 5 and the countersunk nut 6 in the protection body 1, the screw rod 5 enters the protection body 1. And as the screw rod 5 continues to rotate, with the position of the countersunk nut 6 unchanged, the screw rod 5 drives the joint maintenance pad 2 to continuously approach the protection body 1 until the joint maintenance pad 2 fits against the side of the protection body 1. A fixed ring 14 is fixedly connected to the surface of the screw rod 5. A rotating ring 15 located in the installation groove 9 is rotatably connected to the surface of the fixed ring 14. The outer wall of the rotating ring 15 is slidably connected to one side wall of the installation groove 9. The cooperation between the arranged rotating ring 15 and the fixed ring 14 can ensure that when the screw rod 5 fits against the wall of the installation groove 9, the screw rod 5 can rotate smoothly due to the rotation of the fixed ring 14. At the same time, when the screw rod 5 is inserted into the protection body 1, under the interference of the rotating ring 15, the joint maintenance pad 2 approaches the protection body 1.

[0027] In order to drive the screw 5 to rotate: a connecting plate 16 is slidably connected to the position near the end face of the screw 5 in the installation groove 9, and two sprocket wheels 11 are rotatably connected to one side of the connecting plate 16, and a chain 10 is meshed and connected between the two sprocket wheels 11, and one end face of the sprocket wheels 11 is fixed to the end face of the screw 5 located in the installation groove 9, and a worm wheel 12 is rotatably connected to the other sprocket wheel 11 on the other side of the connecting plate 16, and one end of the worm wheel 12 is fixed to the end face of the other sprocket wheel 11, and a worm 13 meshed and connected to the worm wheel 12 is rotatably connected to the other side of the connecting plate 16. The cover plate 3 is opened by sliding up, and the personnel first adjusts the position of the joint maintenance pad 2 so that the screw 5 in the joint maintenance pad 2 corresponds to and fits with the corresponding countersunk nut 6, and then the personnel rotates the worm 13 to realize that the meshed worm wheel 12 drives the corresponding sprocket wheel 11 to rotate, and under the transmission action of the chain 10, the other sprocket wheel 11 drives the screw 5 to rotate.

[0028] The protection body 1 is located on both sides of the joint maintenance pad 2 for fixing: a connecting strip 4 is fixedly connected between a plurality of plug-in columns 7 located on one side of the joint maintenance pad 2, one side of the connecting strip 4 extends to the outside of the joint maintenance pad 2, and is connected to the side of the protection body 1 by bolts. By moving the connecting strip 4, the plug-in column 7 can be slid in the slot 17 to be inserted into the cavity on the side of the protection body 1, which can prevent the joint maintenance pad 2 and the protection body 1 from rotational misalignment. In addition, the plug-in column 7 can be pulled out of the cavity by sliding the connecting strip 4, and when the screw rod 5 is not threadedly connected to the countersunk nut 6, the joint maintenance pad 2 can be slid out of between the two protection bodies 1.

[0029] Optimize the protection body 1: a plurality of partitions 8 are inserted into the inner side of the protection body 1 from top to bottom, and the side of the protection body 1 is fixed by expansion bolts. The plurality of partitions 8 are arranged to facilitate placement of a plurality of pipelines between the two protection bodies 1.

[0030] Working principle: after the pipeline is laid according to the predetermined route, the pipeline main body is covered with two protective bodies 1, and then the two protective bodies 1 are fixed. After the two sections of the pipeline joints are assembled, the joint inspection pad 2 is installed at the joint. The two joint inspection pads 2 are assembled and fixed by plugging the plug column 7 into the cavity and threadedly connecting the screw 5 with the countersunk nut 6. When inspecting the joint, it is only necessary to rotate the worm 13 to realize the meshing connection of the worm wheel 12 to drive the corresponding sprocket 11 to rotate. Under the transmission action of the chain 10, the other sprocket 11 drives the screw 5 to rotate, so that the screw 5 is separated from the countersunk nut 6, and then the connecting strip 4 is slid to pull the plug column 7 out of the cavity. When the screw 5 is not threadedly connected with the countersunk nut 6, the joint inspection pad 2 is slid and pulled out from between the two protective bodies 1.

[0031] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
