[0038] Referring to FIG. 1 and FIG. 2, a schematic diagram of the use of a disk cover safety disassembly and assembly tool in an embodiment of the present application is shown. The disk cover safety disassembly and assembly tool includes a first support seat 100, a second support seat 200, a movable beam 300 and a lifting mechanism 400. A first mounting portion 110 is provided at one end of the first support seat 100, and a first connecting portion 120 is provided at the other end of the first support seat 100. The first mounting portion 110 is used to be detachably mounted on the component to be repaired 10. Specifically, the component to be repaired 10 can be a pipeline or a cavity, and the pipeline or the cavity is provided with a disk cover 20 to cover it. A second mounting portion 210 is provided at one end of the second support seat 200, and a second connecting portion 220 is provided at the other end of the second support seat 200. The second mounting portion 210 is used to be detachably mounted on the component to be repaired 10, and the second mounting portion 210 is installed on the opposite side of the first mounting portion 110. That is, the first mounting portion 110 and the second mounting portion 210 are respectively installed on the opposite sides of the component to be repaired 10 when in use. One end of the movable beam 300 is movably connected to the first connection part 120, and the other end of the movable beam 300 is detachably connected to the second connection part 220. The lifting mechanism 400 is disposed on the movable beam 300, and is used to lift the plate cover 20 of the component 10 to be repaired.

[0039] The disk cover safety disassembly and assembly tool described in the embodiment of the present application is configured by installing the first mounting portion 110 of the first support seat 100 and the second mounting portion 210 of the second support seat 200 on both sides of the component to be repaired 10, and the movable beam 300 is arranged across the upper end of the disk cover 20, and the two ends of the movable beam 300 are respectively connected to the first connection portion 120 of the first support seat 100 and the second connection portion 220 of the second support seat 20. After the bolts of the disk cover 20 are removed, the lifting mechanism 400 on the movable beam 300 is operated to connect the disk cover 20. After the lifting mechanism 400 lifts the disk cover 20 smoothly, the movable beam 300 is disconnected from the second connection portion 220. The movable beam 300 uses the first support seat 100 as a fulcrum, thereby conveniently driving the disk cover 20 to move to one side of the component to be repaired 10, so as to repair the inside of the component to be repaired 10. When the repair is completed, the movable beam 300 is moved back to its original position, and then the disk cover is lowered and covered on the component to be repaired 10 through the lifting mechanism 400, thereby completing the installation.

[0040] The disk cover safety disassembly and assembly tool described in the embodiment of the present application is achieved by installing the disk cover safety disassembly and assembly tool on the component 10 to be repaired, and then the lifting mechanism 400 lifts the disk cover 20 and can be easily transferred to one side. The overall structure is simple, and only one person is required to complete the disassembly and assembly of the disk cover 20. Moreover, there is no need for manual direct handling of the disk cover 20 during the disassembly and assembly process, which not only solves the problem of manual disassembly and assembly due to the heavy disk cover 20 and the small space where it is difficult to exert force, which may cause it to fall, but also solves the problem of no safe place to put the disk cover 20 after it is removed. It has the advantages of high safety and easy use.

[0041] As shown in FIG3 , FIG3 shows a schematic diagram of the structure of a disk cover safety disassembly tool in an embodiment of the present application. In some embodiments, the first connection portion 120 is provided with a first connection hole 120A, one end of the movable beam 300 is provided with a second connection hole 300A, and the first connection hole 120A and the second connection hole 300A are rotatably connected through a first fastener 310. Specifically, the first fastener 310 is a screw or a bolt. Since one end of the movable beam 300 needs to rotate around the first connection part 120, the first connection hole 120A of the first connection part 120 and the second connection hole 300A of the movable beam 300 are movably connected through the first fastener 310, so that the movable beam 300 and the first connection part 120 are hinged, so that the movable beam 300 rotates in a plane with the first connection part 120 as a fulcrum. When the movable beam 300 is connected to the disk cover 20 and lifted, the disk cover 20 can be conveniently rotated and transferred to the other side through the movable beam 300, thereby solving the safety hazards of manual transportation of the disk cover 20 and the problem of no safe place to put the disk cover 20 after removal.

[0042] In an optional embodiment, as shown in FIG2 and FIG3, the second connection part 220 is provided with a third connection hole 220A, and the end of the movable beam 300 away from the second connection hole 300A is provided with a fourth connection hole 300B, and the third connection hole 220A is detachably connected to the fourth connection hole 300B through a latch 320. The connection between the movable beam 300 and the second connection part 220 is a detachable connection, so the third connection hole 220A of the second connection part 220 and the fourth connection hole 300B of the movable beam 300 are connected by the latch 320. When the disk cover 20 is lifted or lowered, the latch 320 locks the detachable end of the movable beam 300 to ensure the stability of the movable beam 300, and ensure that the position of the movable beam 300 quickly corresponds to the lifting position of the disk cover 20, thereby improving efficiency.

[0043] In an optional embodiment, as shown in Figures 2 and 3, the lifting mechanism 400 includes a first lifting rod 410, a second lifting rod 420, a first lifting assembly 430 and a second lifting assembly 440. The first lifting assembly 430 and the second lifting assembly 440 are both installed on the movable beam 300. One end of the first lifting rod 410 is movably connected to the first lifting assembly 430, and the other end of the first lifting rod 410 is used for detachably connecting to the disk cover 20. One end of the second lifting rod 420 is movably connected to the second lifting assembly 440, and the other end of the second lifting rod 420 is used for detachably connecting to the disk cover 20. The first lifting assembly 430 and the second lifting assembly 440 are used to jointly lift the disk cover 20. In order to enable the lifting mechanism 400 to be connected to the disk cover 20 for lifting and lowering, a first lifting component 430 and a second lifting component 440 are arranged on the movable beam 300, and the two ends of the first lifting rod 410 are respectively connected to the disk cover 20 and the first lifting component 430, and the two ends of the second lifting rod 420 are respectively connected to the disk cover 20 and the second lifting component 440. When the first lifting component 430 drives the first lifting rod 410 to lift and lower, and the second lifting component 440 drives the second lifting rod 420 to lift and lower, the disk cover 20 is driven to lift and lower, avoiding manual direct handling of the disk cover 20, thereby avoiding the safety problem of the disk cover 20 or the staff falling.

[0044] It should be noted that the first lifting assembly 430 and the second lifting assembly 440 can be a manual operation structure or an automatic lifting structure. In some embodiments, the first lifting assembly 430 and the second lifting assembly 440 are both drive motors, and the first lifting rod 410 and the second lifting rod 420 can be driven by the drive motor to automatically lift the disk cover 20.

[0045] In other embodiments, as shown in FIG. 2 and FIG. 3 , the first lifting rod 410 and the second lifting rod 420 are both threaded rods, the first lifting rod 410 is connected to the disk cover 20 via a first thread pair, and the second lifting rod 420 is connected to the disk cover 20 via a second thread pair. Since the disk cover 20 is usually connected to the component to be repaired 10 via bolts, a plurality of threaded holes are provided on the disk cover 20. By setting the first lifting rod 410 and the second lifting rod 420 as threaded rods, the first lifting rod 410 and the second lifting rod 420 can be directly connected to the threaded holes on the disk cover 20, which has the advantage of being convenient to use.

[0046] Further, as shown in FIG3 , the first lifting assembly 430 includes a first worm gear 431, which is rotatably mounted on the movable beam 300, and is provided with a first threaded hole 431A, and the first lifting rod 410 is movably screwed to the first threaded hole 431A. The second lifting assembly 440 includes a second worm gear 441, which is rotatably mounted on the movable beam 300, and is provided with a second threaded hole 441A, and the second lifting rod 420 is movably screwed to the second threaded hole 441A. By passing the first lifting rod 410 through the first threaded hole 431A of the first worm gear 431, and the second lifting rod 420 through the second threaded hole 441A of the second worm gear 441, when the staff manually rotates the first worm gear 431 and the second worm gear 441, the first lifting rod 410 and the second lifting rod 420 can be driven by the thread pair, thereby lifting the disk cover 20.

[0047] Furthermore, as shown in FIG3 , the lifting mechanism 400 further includes a transmission shaft 450, and a first thread 451 and a second thread 452 are respectively provided at both ends of the transmission shaft 450, the first thread 451 is meshedly connected with the teeth of the first worm gear 431, and the second thread 452 is meshedly connected with the teeth of the second worm gear 441. The first worm gear 431 and the second worm gear 441 are transmission-connected by providing the transmission shaft 450, and when the first worm gear 431 rotates, the second worm gear 441 is driven to rotate through the transmission shaft 450, thereby ensuring that the two connection ends of the disk cover 20 are synchronously lifted and lowered, so that the lifting and lowering of the disk cover 20 is more stable.

[0048] In an optional embodiment, a component flange 11 is usually provided at one end of the component 10 to be inspected that is close to the disk cover 20. As shown in Figures 2 and 3, in order to fasten the first mounting portion 110 and the second mounting portion 210 to the component flange 11, the first mounting portion 110 includes a first protrusion 111, a second protrusion 112 and a second fastener 113. The first protrusion 111 and the second protrusion 112 are arranged on one side of the first support seat 100 along the height direction of the first support seat 100. A first embedding groove 110A is provided between the first protrusion 111 and the second protrusion 112. The first embedding groove 110A is used to be installed on the component flange 11. The first protrusion 111 is provided with a first through hole 111A. The second fastener 113 is installed in the first through hole 111A. The second fastener 113 is used to abut the component flange 11. By setting a first protrusion 111 and a second protrusion 112 on one side of the first support seat 100 close to the component 10 to be repaired, a first embedding groove 110A is formed between the two, so that a connection is formed by embedding the component flange 11 into the first embedding groove 110A, and the second fastener 113 is abutted and locked to complete the installation of the first support seat 100, which has the advantage of easy use.

[0049] Similarly, as shown in Figures 2 and 3, the second mounting portion 210 includes a third protrusion 211, a fourth protrusion 212 and a third fastener 213. The third protrusion 211 and the fourth protrusion 212 are arranged on one side of the second support seat 200 along the height direction of the second support seat 200. A second embedding groove 210A is provided between the third protrusion 211 and the fourth protrusion 212. The second embedding groove 210A is used to be installed on the component flange 11. The third protrusion 211 is provided with a second through hole 211A. The third fastener 213 is installed in the second through hole 211A. The third fastener 213 is used to abut the component flange 11. By setting a third protrusion 211 and a fourth protrusion 212 on one side of the second support seat 200 close to the component 10 to be repaired, a second embedding groove 210A is formed between the two, so that a connection is formed by embedding the component flange 11 on the other side into the second embedding groove 210A, and the third fastener 213 is abutted and locked to complete the installation of the second support seat 210, which has the advantage of easy use.

[0050] In an optional embodiment, when the component 10 to be repaired is a pipeline, as shown in Figures 2 and 3, the side surfaces of the first protrusion 111, the second protrusion 112, the third protrusion 211, and the fourth protrusion 212 facing the component 10 to be repaired are all concave arc surfaces. By setting the side surfaces of the first protrusion 111, the second protrusion 112, the third protrusion 211, and the fourth protrusion 212 abutting against the component 10 to be repaired as concave arc surfaces, the first protrusion 111, the second protrusion 112, the third protrusion 211, and the fourth protrusion 212 are more closely fitted to the component 10 to be repaired, thereby improving the connection stability of the first support seat 100 and the second support seat 200.

[0051] In an optional embodiment, as shown in FIG. 4 , the movable beam 300 is provided with a reinforcing rib 330, which is arranged on the bottom surface of the movable beam 300. The reinforcing rib 330 includes a plurality of ribs, which are arranged in a crisscross grid shape. By arranging the reinforcing rib 330 on the movable beam 300, the strength of the movable beam 300 is higher, the heavy plate cover 20 has better stability, and the movable beam 300 is prevented from breaking, which has the advantage of high safety. Moreover, the reinforcing rib 330 is a grid-shaped reinforcement structure composed of crisscross ribs, which can enhance the strength and stability of the movable beam 300 in two directions at the same time, so that the movable beam 300 can have better resistance when subjected to external forces in different directions.

[0052] The disk cover installation and disassembly tool described in the embodiment of the present application has the following beneficial effects:

[0053] 1. The disc cover safety disassembly and assembly tool is installed on the component to be repaired 10, and then the lifting mechanism 400 lifts the disc cover 20 and can be easily transferred to one side. Only one person is needed to complete the disassembly and assembly of the disc cover 20, and there is no need to directly carry the disc cover 20 manually during the disassembly and assembly process. This solves the problem of manual disassembly and assembly due to the heavy disc cover 20 and the small space where it is difficult to exert force, which may cause it to fall, and solves the problem of no safe place to put the disc cover 20 after it is removed. It has the advantages of high safety and convenient use.

[0054] 2. The first worm gear 431 and the second worm gear 441 are connected by setting a transmission shaft 450. When the first worm gear 431 rotates, the second worm gear 441 is driven to rotate through the transmission shaft 450, thereby ensuring that the two connecting ends of the disk cover 20 are lifted and lowered synchronously, so that the lifting and lowering of the disk cover 20 is smoother.
