In addition, hydraulic bolts face many problems during disassembly: For example, high preload: Hydraulic bolts usually apply high preload to ensure a secure connection. This force needs to be overcome during disassembly, which is difficult for traditional tools to handle.

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0024] like Figures 1 to 4 As shown, a disassembly device for ship hydraulic bolts according to an embodiment of the present invention comprises a disassembly body 1, wherein the disassembly body 1 is formed in an integrated manner by a plurality of curved brackets 101, wherein a handle 2 is fixedly connected to the outer circumferential surface of one of the curved brackets 101, and a collar frame 3 is installed inside the disassembly body 1, wherein a plurality of collar frames 3 are provided and are designed to be spaced apart, and an engaging plate 301 is rotatably connected between adjacent collar frames 3, and a circular shaft 302 adapted to the engaging plate 301 is provided on the upper side of the inner wall of the collar frame 3, and a thread adapted to the stud to be disassembled is provided on the inner wall of the engaging plate 301, and the engaging plate 301 is used to cooperate with the stud to be disassembled and rotate the stud to be disassembled; During work, currently professional equipment is required for disassembling hydraulic bolts, but due to the various sizes of bolts, different disassembly equipment needs to be replaced when disassembling different hydraulic bolts; when using the disassembly device in the embodiment of the present invention, the disassembly device is carried to the side of the hydraulic bolt to be disassembled by the handle 2, and then the collar frame 3 is aligned with the stud of the hydraulic bolt to be disassembled and sleeved on the outer circumference of the stud, and then all the meshing plates 301 are rotated toward the side close to the stud through the circular shaft 302, so that the threads on the inner wall of the meshing plate 301 are meshed with the threads on the outer circumference of the stud, and the collar frame 3 drives all the meshing plates 301 to rotate, that is, drives the stud to rotate, so that the stud is loosened to a certain extent, and then the nut is screwed out from the stud, so that the nut and the stud can be unscrewed without damaging the nut and the stud, and all the meshing plates 301 are set to a rotating design, which can adapt to different types of studs, improve the practicality of the disassembly device, and bring convenience to the subsequent maintenance and replacement of the ship.

[0025] like Figures 2 to 6 As shown, the end of the handle 2 away from the curved bracket 101 is fixedly connected to a driving motor 4, and a connecting shaft 5 is fixedly installed on the telescopic end of the driving motor 4. The bottom end of the connecting shaft 5 is provided with a disassembly frame 6, and a plurality of the engaging plates 301 are located below the disassembly frame 6; during operation, when all the engaging plates 301 are combined with the studs, the driving motor 4 is controlled to drive the connecting shaft 5 to rotate, and the connecting shaft 5 drives the disassembly frame 6 and all the engaging plates 301 to rotate, so that the engaging plate 301 will drive the studs matched therewith to rotate, so the studs can be loosened first, and then the nut can be screwed out, and the operation is more convenient.

[0026] The disassembly frame 6 includes a mounting seat 7 installed below the connecting shaft 5, an electric telescopic column 8 is fixedly installed at the bottom of the mounting seat 7, a fitting plate 801 is fixedly installed at the telescopic end of the electric telescopic column 8, and a plurality of pressure frames 9 are fixedly installed on the lower end surface of the fitting plate 801. The plurality of pressure frames 9 and the plurality of meshing plates 301 are arranged in a one-to-one correspondence, and the bottom end of the pressure frame 9 contacts the side wall of the meshing plate 301; During operation, when the ring frame 3 moves down along the top of the stud, the engaging plate 301 has not yet cooperated with the stud, so the telescopic end of the electric telescopic column 8 can be controlled to move, and the telescopic end of the electric telescopic column 8 drives the fitting plate 801 to move down, and the fitting plate 801 drives the pressure frame 9 to move down. Since the bottom end of the pressure frame 9 contacts the side wall of the engaging plate 301, the pressure frame 9 will squeeze the engaging plate 301 during the downward movement, so that the engaging plate 301 rotates toward the side close to the stud, and then all the engaging plates 301 will be fitted on the outer peripheral surface of the stud, and then the stud can be initially loosened by the drive of the above-mentioned drive motor 4. Under the rotation design of all the engaging plates 301, it is convenient to cooperate with the studs of different hydraulic bolts, and it is convenient to disassemble different types of hydraulic bolts, and it has a wide range of uses.

[0027] like Figures 3 to 6 As shown, the side wall of the meshing plate 301 is fixedly connected with a connecting frame 10, the inner wall of the connecting frame 10 is provided with an arc plate 11, the side wall of the pressure frame 9 is in contact with the arc end of the arc plate 11, the side wall of the pressure frame 9 is provided with a limiting groove 12, the arc plate 11 is located at the groove wall of the limiting groove 12, and the width of the arc plate 11 is adapted to the width of the limiting groove 12; when working, refer to the attached Figure 3 and Figure 5 As shown, when the pressure frame 9 moves downward, the limiting groove 12 on the side wall of the pressure frame 9 will move downward along the curved surface of the arc plate 11, and the groove wall of the limiting groove 12 will squeeze the curved end of the arc plate 11, thereby causing the engaging plate 301 to rotate toward the side close to the stud. Furthermore, since the width of the arc plate 11 is compatible with the width of the limiting groove 12, that is, under the limitation of the two, when the connecting shaft 5 drives the mounting seat 7, the bonding plate 801, and the pressure frame 9 to rotate, all the pressure frames 9 will simultaneously drive all the engaging plates 301 to rotate, that is, the studs will be loosened.

[0028] A limiting ring 102 is arranged on the outer side of the connecting shaft 5, and the connecting shaft 5 passes through the inside of the limiting ring 102; an oil storage tank 13 is installed on the lower end surface of the collar frame 3, and lubricating oil is stored in the oil storage tank 13; the lower end surface of the limiting ring 102 is connected to the top end surface of the mounting seat 7 through a bracket; The inner wall of the limit ring 102 is provided with a control unit, which is used to control the lubricating oil inside the oil storage tank 13 to spray out; Figure 6 As shown, the connecting shaft 5 passes through the interior of the limiting ring 102, and the lower end surface of the limiting ring 102 is connected to the top end of the electric telescopic column 8 through a bracket; When the driving motor 4 drives the connecting shaft 5 to rotate, the connecting shaft 5 will drive the limit ring 102 and the electric telescopic column 8 to rotate through the control unit; since there are two situations when loosening the stud, one is: the stud can be directly driven to loosen, and the other is that the stud is difficult to loosen, that is, it needs lubrication of lubricating oil to loosen slowly. When the second situation occurs, under the action of the control unit, the lubricating oil inside the oil storage tank 13 can be controlled to spray out and spray to the connection between the stud and the nut, which can facilitate the loosening of the stud.

[0029] like Figures 3 to 9 As shown, the control unit includes a limiting groove 14 opened on the inner wall of the limiting ring 102, and the limiting groove 14 is provided in plurality and is opened on the inner wall of the limiting ring 102 in a circular array, and a limiting convex seat 15 is fixedly installed on the outer circumference of the connecting shaft 5, and a contact 1 151 is fixedly installed on the outer circumference of one of the limiting convex seats 15, and a contact 2 121 is fixedly installed on the groove wall of the limiting ring 102, and the contact 1 151 and the contact 2 121 are designed to be on the same horizontal plane, and the contact 2 121 is connected to the external controller through a power cord; When working, refer to the attached Figure 6 As shown, under normal circumstances, the limiting convex seat 15 is located inside the limiting groove 14, so when the connecting shaft 5 rotates, the connecting shaft 5 will drive the limiting ring 102 to rotate through the limiting of the limiting convex seat 15 and the limiting groove 14, and the limiting ring 102 drives the bottom bracket and the electric telescopic column 8 to rotate, so as to achieve the loosening of the stud; When the stud and the nut are too close together, that is, the stud is difficult to loosen, the driving motor 4 drives the connecting shaft 5 to rotate, and the stud below is difficult to rotate. The connecting shaft 5 will drive the limiting convex seat 15 to gradually separate from the limiting groove 14, and then the contact 1 151 on the outer peripheral surface of the limiting convex seat 15 will contact the contact 2 121 on the groove wall of the limiting ring 102, so the external circuit is connected, the driving motor 4 is stopped first, and then the lubricating oil in the oil storage tank 13 is controlled to spray out, so as to achieve the lubrication operation between the stud and the nut; It should be noted that, since the stud at the bottom is difficult to rotate, and the connecting shaft 5 is still driven by the driving force of the driving motor 4, the connecting shaft 5 will drive the limiting protrusion 15 to gradually separate from the limiting groove 14, which not only protects the stud and the nut itself, but also improves the disassembly speed of the stud; It should be further explained that after the lubricating oil in the oil storage tank 13 is sprayed out, after a certain period of time, the drive motor 4 is controlled to drive the connecting shaft 5 to rotate, so that the connecting shaft 5 drives the limiting protrusion 15 to move to the inside of the limiting groove 14 again, and the above operation is performed, so that the stud that is difficult to loosen can be loosened.

[0030] The material of the limiting boss 15 is hard rubber, and the shape of the limiting boss 15 is matched with the shape of the limiting groove 14; when working, since the material of the limiting boss 15 is hard rubber, it not only gives the limiting ring 102 sufficient limiting force, but also can push the limiting boss 15 out from the inside of the limiting groove 14 to a certain extent, so as to facilitate the lubricating oil inside the oil storage tank 13 to be sprayed out.

[0031] The oil storage tanks 13 are arranged in two groups and are symmetrically designed relative to the ring frame 3. An oil outlet pipe 16 is installed at the lower end of the oil storage tank 13. Adjacent oil storage tanks 13 are connected by connecting pipes 17, and the connecting pipes 17 are externally connected to the oil delivery pipe. When working, the connecting pipes 17 are designed, and oil can be delivered to the inside of the oil storage tank 13 through the connecting pipes 17 and the external oil pipe, so as to facilitate the replenishment of lubricating oil in the oil storage tank 13.

[0032] A circular sleeve 18 is installed at the bottom of the curved bracket 101, and two groups of electric push columns 19 are installed on the inner wall of the circular sleeve 18. A fastening plate 20 is fixedly installed at the telescopic end of the electric push column 19; the side wall shape of the fastening plate 20 is serrated. During operation, when the disassembly body 1 moves downward along the bolt to be disassembled, the circular sleeve 18 will fall into the outside of the nut. At this time, the electric push column 19 is controlled to drive the fastening plate 20 to move, so that the fastening plate 20 is pressed on the outside of the nut. In this way, the nut can be limited first, which facilitates the loosening of the stud by the above operation. After the stud is loosened, the disassembly body 1 is taken out, and then the nut can be manually screwed out.

[0033] During work, currently professional equipment is required for disassembling hydraulic bolts, but due to the various sizes of bolts, different disassembly equipment needs to be replaced when disassembling different hydraulic bolts; when using the disassembly device in the embodiment of the present invention, the disassembly device is carried to the side of the hydraulic bolt to be disassembled by the handle 2, and then the collar frame 3 is aligned with the stud of the hydraulic bolt to be disassembled, and is sleeved on the outer circumference of the stud, and then all the meshing plates 301 are rotated toward the side close to the stud through the circular shaft 302, so that the threads on the inner wall of the meshing plate 301 are meshed with the threads on the outer circumference of the stud, and the collar frame 3 drives all the meshing plates 301 to rotate, that is, drives the stud to rotate, so that the stud is loosened to a certain extent, and then the nut is screwed out from the stud, so that the nut and the stud can be undamaged, and all the meshing plates 301 are set to a rotating design, which can adapt to different types of studs, improve the practicality of the disassembly device, and bring convenience to the subsequent maintenance and replacement of the ship; When all the meshing plates 301 are engaged with the studs, the driving motor 4 is controlled to drive the connecting shaft 5 to rotate, and the connecting shaft 5 drives the disassembly frame 6 and all the meshing plates 301 to rotate, so that the meshing plates 301 will drive the studs matched with them to rotate, so the studs can be loosened first, and then the nuts can be unscrewed, and the disassembly steps are more convenient to operate; when the collar frame 3 moves down along the top of the stud, the meshing plate 301 has not yet matched with the stud, so the telescopic end of the electric telescopic column 8 can be controlled to move, and the telescopic end of the electric telescopic column 8 drives the fitting plate 801 to move down , the fitting plate 801 drives the pressure frame 9 to move downward. Since the bottom end of the pressure frame 9 contacts the side wall of the meshing plate 301, the pressure frame 9 will squeeze the meshing plate 301 during the downward movement, so that the meshing plate 301 rotates toward the side close to the stud. Then, all the meshing plates 301 will fit on the outer peripheral surface of the stud. Then, the stud can be initially loosened by the drive of the above-mentioned drive motor 4. Under the rotation design of all the meshing plates 301, it is convenient to match the studs of different hydraulic bolts and to disassemble different types of hydraulic bolts. It has a wide range of uses. See attached Figure 3 and Figure 5 As shown, when the pressure frame 9 moves downward, the limiting groove 12 on the side wall of the pressure frame 9 will move downward along the arc surface of the arc plate 11, and the groove wall of the limiting groove 12 will squeeze the arc end of the arc plate 11, so that the meshing plate 301 rotates toward the side close to the stud. Furthermore, since the width of the arc plate 11 is adapted to the width of the limiting groove 12, that is, under the limit of the two, when the connecting shaft 5 drives the mounting seat 7, the bonding plate 801, and the pressure frame 9 to rotate, all the pressure frames 9 will simultaneously drive all the meshing plates 301 to rotate, that is, Drive the stud to loosen; when the driving motor 4 drives the connecting shaft 5 to rotate, the connecting shaft 5 will drive the limit ring 102 and the electric telescopic column 8 to rotate through the control unit; because there are two situations when the stud is loosened, one is: the stud can be directly driven to loosen, and the other is that the stud is difficult to loosen, that is, it needs lubrication of lubricating oil to loosen slowly. When the second situation occurs, under the action of the control unit, the lubricating oil inside the oil storage tank 13 can be controlled to spray out and spray to the connection between the stud and the nut, so that the stud can be easily loosened; See attached Figure 6 As shown, under normal circumstances, the limiting convex seat 15 is located inside the limiting groove 14, so when the connecting shaft 5 rotates, the connecting shaft 5 will drive the limiting ring 102 to rotate through the limiting of the limiting convex seat 15 and the limiting groove 14, and the limiting ring 102 drives the bottom bracket and the electric telescopic column 8 to rotate, so as to achieve the loosening of the stud; When the stud and the nut are too close, that is, the stud is difficult to loosen, at this time, the driving motor 4 drives the connecting shaft 5 to rotate, and the lower stud is difficult to rotate. The connecting shaft 5 will drive the limiting convex seat 15 to gradually disengage from the limiting groove 14, and then the contact 1 151 on the outer peripheral surface of the limiting convex seat 15 will contact the contact 2 121 of the groove wall of the limiting ring 102, so the external circuit is connected, the driving motor 4 is stopped first, and then the lubricating oil inside the oil storage tank 13 is controlled to spray out, so as to achieve the lubrication operation between the stud and the nut; when the disassembly main body 1 moves downward along the bolt to be disassembled, the circular sleeve 18 will fall on the outside of the nut, and at this time, the electric push column 19 is controlled to drive the fastening plate 20 to move, so that the fastening plate 20 is pressed on the outside of the nut, so that the nut can be limited first, which is convenient for the above operation to loosen the stud, and after the stud is loosened, the disassembly main body 1 is taken out, and then the nut is manually screwed out.
