Description

Technical Field

[0001] The invention relates to the technical field of dredgers, and in particular to an installation structure of a curved pipe upper limiter for a trailing suction dredger. Background Art

[0002] A limit sensor is a device used to measure or detect the position of an object. It determines when an object has reached or exceeded a preset position limit, based on physical contact or non-contact performance between the object and the sensor.

[0003] During the construction of the dredger, due to strong winds and waves, the curved pipe connected to the dredger arm on the hanger is directly hit, causing the upper limit sensor cable of the curved pipe to be damaged and water to enter, or the spring of the movable sensing frame is stuck, making the sensor ineffective. When the dredger is lowered, the upper limit cannot be sensed. At this time, the general solution is for personnel to go to the site to check the problem. For example, if it is confirmed that the site is stuck, the movable frame can be knocked. However, if water enters, the only option is to notify the electrician to repair the sensor. Both methods are time-consuming and labor-intensive, and sometimes they cannot achieve results, and there are many accidental factors. Summary of the invention

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two components; for ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Example: Refer to Figure 1 , Figure 4 , Figure 5 and Figure 6A mounting structure of a curved pipe upper limiter for a trailing suction dredger comprises a supporting plate 2 fixedly mounted on a ship support 1, the supporting plate 2 comprising a lower supporting plate 201 and an upper supporting plate 202, a guide rod 3 is arranged between the lower supporting plate 201 and the upper supporting plate 202, a mounting seat 4 is slidably connected to the outer side of the guide rod 3, a clamp 401 is connected to the mounting seat 4 by bolts, a sensor body 5 is arranged between the clamp 401 and the mounting seat 4, a positioning assembly is arranged on the mounting seat 4, a positioning groove 10 matched with the positioning assembly is opened on the ship support 1, the positioning groove 10 is placed on the lower side of the ship winch, a gravity sensing block 6 is rotatably connected to the mounting seat 4 by a pin shaft, the gravity sensing block 6 is movably opposed to a follower block 7 on the slide rail 101 of the ship support 1 that slides with the curved pipe, and a lifting assembly for lifting the mounting seat 4 is arranged on the ship support 1.

[0031] Specifically, by moving the sensor body 5, i.e., the limit sensor, to the lower part of the ship's winch to avoid being hit by waves, the complex movable sensing frame is changed into a gravity sensing block 6, and the curved pipe moves upward to lift the gravity sensing block 6. The sensor body 5 detects the gravity sensing block 6 and obtains the upper limit position. When the curved pipe is lowered, the gravity sensing block 6 disengages the sensing downward by its own gravity, reducing the distance with the sensor, making the sensing sensitive, reducing and eliminating the phenomenon of the sensor not sensing and getting stuck, reducing the time for personnel to go to the site for inspection, processing and repair, increasing time utilization, increasing dredging time, and also canceling the arrangement of personnel specifically going to the site for processing, thereby improving the efficiency of manpower use and reducing labor costs. By setting a lifting component, it is convenient to lift and lower the sensor body 5 set at a high place from a low place, which is convenient for the later maintenance work of the sensor body 5, reducing the danger of the staff's climbing work, and cooperating with the positioning component to stably install the sensor body 5 lifted to a high place at a high place on the ship, thereby improving the stability of the installation of the sensor body 5.

[0032] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As a preferred technical solution of the present invention, the pulling assembly includes a rotating rod 8 rotatably connected to the ship support 1, a first drum 801 is provided on the rotating rod 8, a first pull rope 802 is provided on the first drum 801, and one end of the first pull rope 802 away from the first drum 801 passes through the upper support plate 202 and is fixedly connected to the top of the mounting seat 4.

[0033] Furthermore, two guide rods 3 are provided, and both guide rods 3 are slidably connected to the mounting seat 4 .

[0034] Specifically, when controlling the lifting and lowering of the mounting seat 4, the rotating rod 8 is rotated to drive the first reel 801 to rotate, and then the first reel 801 reels or releases the first pull rope 802, so that the mounting seat 4 is pulled up or lowered along the guide rod 3, which is convenient for the subsequent maintenance or replacement of the sensor body 5 on the mounting seat 4.

[0035] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As a preferred technical solution of the present invention, the positioning assembly includes a movable groove 9 opened in the mounting seat 4, a positioning block 901 slidably connected in the movable groove 9, and an elastic element 902 arranged between the inner wall of the movable groove 9 and the positioning block 901, and the positioning block 901 is inserted in the positioning groove 10.

[0036] Furthermore, the lifting assembly also includes a second reel 803 arranged on the rotating rod 8, and a second pull rope 804 is wound around the second reel 803. One end of the second pull rope 804 away from the second reel 803 passes through the mounting seat 4 and is connected to the positioning block 901.

[0037] Specifically, when the rotating rod 8 rotates clockwise, the first drum 801 reels the first pull rope 802, and the second drum 803 releases the second pull rope 804, so that the first pull rope 802 drives the mounting seat 4 to move upward, and the second pull rope 804 no longer applies tension to the positioning block 901. After the first pull rope 802 pulls the mounting seat 4 to a high position, the positioning block 901 is at the same height as the positioning groove 10. At this time, the positioning block 901, which is not subject to tension, moves under the elastic force of the elastic element 902. The positioning block 901 is inserted into the positioning groove 10, thereby realizing the stable installation of the mounting seat 4 and the ship bracket 1, and ensuring the accuracy of the detection of the sensor body 5; when the mounting seat 4 needs to be lowered, the rotating rod 8 rotates counterclockwise, and the second pull rope 804 pulls the positioning block 901 to shrink the positioning block 901 in the movable groove 9, and the first pull rope 802 lowers the mounting seat 4, and cooperates with the second pull rope 804 to pull down the mounting seat 4 through the positioning block 901, so that the mounting seat 4 moves downward.

[0038] Reference Figure 1 and Figure 3As a preferred technical solution of the present invention, a driving gear 11 is provided on the rotating rod 8, and a driven gear 12 rotating on the ship support 1 is meshed and connected on the outer side of the driving gear 11, and a rotating rod 121 is provided on the driven gear 12, and two eccentric shafts 122 are provided on the rotating rod 121, and each eccentric shaft 122 is provided with a collar 123, and a connecting rod 124 is fixed on the collar 123, and an end of the connecting rod 124 away from the collar 123 is movably connected to a movable ring 13, and an elastic telescopic rod 14 is provided between the movable ring 13 and the ship support 1, and a first pull rope 802 and a second pull rope 804 are respectively placed in the two movable rings 13.

[0039] Specifically, when the rotating rod 8 rotates, it drives the driving gear 11 to rotate, and the driving gear 11 meshes with the driven gear 12 on the rotating rod 121 for transmission, thereby causing the rotating rod 121 to rotate. When the rotating rod 121 rotates, the eccentric shaft 122 drives the ring 123 to move, so that the ring 123 cooperates with the connecting rod 124 to reciprocate and pull the movable ring 13 to move, so that the movable ring 13 drives the first pull rope 802 and the second pull rope 804 to swing back and forth, thereby causing the seawater that may be attached to the outside of the first pull rope 802 and the second pull rope 804 to fall off, thereby reducing the corrosion degree of the pull rope to a certain extent and reducing the construction cost; it should be noted that a protective shell should be provided at the meshing point of the driving gear 11 and the driven gear 12 to avoid erosion by seawater. This is common knowledge among people in this field and will not be elaborated here.

[0040] Reference Figure 1 As a preferred technical solution of the present invention, the first pull rope 802 and the second pull rope 804 are sprayed with an anti-corrosion coating on the outside; specifically, the service life of the first pull rope 802 and the second pull rope 804 is effectively improved.

[0043] Specifically, when the rotating rod 121 rotates, the worm 15 engages with the worm wheel 151 on the guide rod 3 for transmission, so that the worm wheel 151 drives the guide rod 3 to rotate. When the guide rod 3 rotates, the cable 161 connected to the sensor body 5 is wound or released through the third reel 16, so that the length of the cable 161 moving out of the third reel 16 is adapted to the lifting and lowering work of the sensor body 5, thereby preventing the cable 161 from being too long or too short and affecting the normal lifting and lowering action of the sensor body 5.
