Description

Technical Field

[0001] This utility model relates to the field of maintenance equipment technology, and in particular to a torque adjustment tooling and synchronous shaft system. Background Technology

[0002] Currently, the main types of vertical ship lifts that have been built or are under construction in China include the wire rope winch fully balanced type, the gear climbing fully balanced type, and the fully balanced hydraulic drive type. Among these, the wire rope winch type with partial balance for launching the ship compartment and the fully balanced hydraulic drive type are currently limited to ship lifts with relatively small ship passage capacity and lifting height. The largest ship lift in China is currently the fully balanced gear climbing type, with a maximum ship passage capacity of 3000 tons and a lifting height of 113 meters.

[0003] According to a flexible shaft torque testing fixture scheme disclosed in publication number CN 221173681 U, the torque after shaft rotation can be tested. However, after long-term use, the internal components of the synchronous shaft system of the ship lift will deform or wear. When the drive system stops, due to the deformation or wear of the components, residual torque remains on the transmission shaft. This residual torque prevents the fasteners of the couplings from being removed, making it impossible to disassemble or replace the equipment in the synchronous shaft system. If the residual torque in the system is completely released directly and the worn components are replaced, many couplings or reversing transmission structure components will not be able to be installed properly, requiring a complete adjustment of the entire synchronous shaft system and affecting the normal operation of the ship lift.

[0004] Therefore, a torque adjustment fixture and synchronous shaft system are proposed, which can counteract the residual torque between local shaft segments in the synchronous shaft system. At the same time, it can solve the technical problems that the connecting fasteners of the coupling cannot be removed due to residual torque, and that it is inconvenient to maintain the synchronous shaft system. Utility Model Content

[0006] This utility model proposes a torque adjustment fixture, comprising: At least two semi-circular rings, with two adjacent semi-circular rings detachably connected, are used to be sleeved around the coupling; At least two anti-rotation components are provided on the inner surfaces of the at least two semi-circular ring components, respectively, and are detachably connected to the at least two semi-circular ring components and the coupling, in order to prevent the at least two semi-circular ring components from rotating relative to the coupling. At least two flexible connectors, one end of which is connected to the at least two semi-circular rings respectively, and the other end is set at the fixing point on the outside of the at least two semi-circular rings, for locking the torque of the coupling.

[0007] Based on the above technical solution, preferably, the at least two anti-rotation members extend toward the center of the semi-circular ring member, and the adjacent ends of the at least two anti-rotation members enclose a hollow anti-rotation part, which is detachably connected to the coupling.

The first fastener passes through the first connecting hole and the second connecting hole to connect at least two anti-rotation parts to the coupling.

[0009] Based on the above technical solutions, preferably, the torque adjustment fixture further includes: A plurality of second fasteners are circumferentially distributed on at least two semi-circular rings. The at least two semi-circular rings are provided with third connecting holes adapted to the second fasteners. The at least two anti-rotation members are provided with fourth connecting holes adapted to the second fasteners. The plurality of second fasteners are sequentially inserted into the third connecting holes and the fourth connecting holes to enable the semi-circular rings and the anti-rotation members to be detachably connected.

[0010] Based on the above technical solutions, preferably, the ends of two adjacent semi-circular rings that abut against each other extend outward in the radial direction to form a splicing part; The torque adjustment fixture also includes: Several third fasteners are provided on the splicing part. Each of two adjacent splicing parts is provided with a fifth connecting hole adapted to the third fastener. The third fasteners are sequentially inserted into the fifth connecting holes of two adjacent splicing parts to make the two adjacent semi-circular rings abut against each other.

[0011] Based on the above technical solution, preferably, the at least two semi-circular rings extend outward from the side that is far apart from each other to form a plurality of hooking parts, each hooking part being provided with a hooking hole for connecting to one end of the flexible connector.

[0012] Based on the above technical solutions, preferably, the length of the flexible connector is adjustable.

[0013] Based on the above technical solutions, preferably, a number of hook parts are circumferentially distributed on the circumferential side surfaces of the at least two semi-circular ring parts.

[0014] Based on the above technical solutions, preferably, the flexible connector is a manual or electric hoist sling.

[0015] On the other hand, the present invention also provides a synchronous shaft system, including: the torque adjustment fixture as described above, a plurality of drive components, a plurality of couplings, and a plurality of reversing transmission components, wherein the plurality of couplings and the plurality of reversing transmission components are used to drive the plurality of drive components, and the torque adjustment fixture is sleeved around the couplings.

In addition, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0026] The technical solution is explained below. In existing solutions, handling residual torque in the synchronous shaft system involves directly releasing all residual torque and then replacing worn parts. This would prevent the proper installation of numerous couplings or reversing drive components, necessitating a complete overhaul of the entire synchronous shaft system and impacting the normal operation of the ship lift. Therefore, if... Figure 1 and Figure 2 As shown, this utility model provides a torque adjustment fixture, comprising: At least two semi-circular ring parts 1, two adjacent semi-circular ring parts 1 are detachably connected, for wrapping around the coupling 100; At least two anti-rotation elements 2 are respectively provided on the inner surface of at least two semi-circular ring elements 1, and are detachably connected to at least two semi-circular ring elements 1 and coupling 100, to prevent at least two semi-circular ring elements 1 from rotating relative to coupling 100. At least two flexible connectors 3 are connected at one end to at least two semi-circular rings 1 respectively, and the other end is set at the fixing point on the outside of at least two semi-circular rings 1 to lock the torque of the coupling 100.

[0027] Two adjacent semicircular ring parts 1 are separated. The semicircular ring parts 1 can be radially fitted onto the coupling 100 and connected to the coupling 100 via anti-rotation parts 2. After the semicircular ring parts 1 are connected to the coupling 100, at least two semicircular ring parts 1 are fixed from at least two directions by flexible connecting parts 3. This allows the flexible connecting parts 3 to lock the torque of the coupling 100 through the two semicircular ring parts 1. When it is necessary to remove parts connected to the coupling 100, it can be ensured that the torque of the coupling 100 will not be output outwards. Therefore, when a part in the synchronous shaft system needs to be replaced, the torque near both ends of the part to be replaced is locked by two sets of torque adjustment fixtures. During the removal and replacement of this part, it can be ensured that the torque of other components in the synchronous shaft system will not be output outwards.

[0028] like Figure 1As shown, at least two anti-rotation members 2 extend toward the center of the semi-circular ring member 1, and the adjacent ends of the at least two anti-rotation members 2 enclose a hollow anti-rotation part, which is detachably connected to the coupling 100.

[0029] Specifically, there are two anti-rotation components 2 and two semi-circular ring components 1. The anti-rotation component 2 is in the shape of a semi-circular plate, and the two anti-rotation components 2 together form an anti-rotation part with a cross-shaped hollow interior.

[0030] like Figure 1 and Figure 2 As shown, in order to ensure a stable connection between the anti-rotation part and the coupling 100, the coupling 100 is provided with a plurality of first connection holes, and a first fastener 110 is connected in each of the first connection holes. The inner surface of the anti-rotation part is provided with several arc-shaped protrusions, and each protrusion is provided with a second connecting hole 201 corresponding to the first fastener 110. The first fastener 110 is inserted into the first connecting hole and the second connecting hole 201 in sequence to connect at least two anti-rotation parts 2 to the coupling 100.

[0031] Specifically, by using a number of first connecting holes on the coupling 100 itself, and by providing second connecting holes 201 on the anti-rotation part corresponding to the first connecting holes, the first fastener 110 can connect the anti-rotation part to the coupling 100.

[0032] More specifically, the coupling 100 is provided with eight first fasteners 110, and four protrusions are formed on the two anti-rotation parts, with the four protrusions circumferentially distributed on the two anti-rotation parts. Each protrusion is provided with a second connecting hole 201 that corresponds to one of the four first fasteners 110. The coupling 100 is connected to the two anti-rotation members 2 through the four protrusions. Each protrusion is located exactly between two adjacent first fasteners 110, and correspondingly, there is also exactly one protrusion between two adjacent first fasteners 110. In this way, the two anti-rotation members 2 can be detachably connected to the coupling 100 through the protrusions, and the anti-rotation members 2 can also avoid the other first fasteners 110 on the coupling 100.

[0033] To enable the semi-circular ring 1 to fix couplings 100 of different outer diameters via anti-rotation parts 2 of different sizes, the following additional components are also included: A plurality of second fasteners 4 are circumferentially distributed on at least two semi-circular rings 1. At least two semi-circular rings 1 are provided with third connecting holes adapted to the second fasteners 4. At least two anti-rotation members 2 are provided with fourth connecting holes 202 adapted to the second fasteners 4. The plurality of second fasteners 4 are sequentially inserted into the third connecting holes and the fourth connecting holes 202 for connecting the semi-circular rings 1 and the anti-rotation members 2.

[0034] Specifically, in couplings 100 with different outer diameters, the position of the first fastener 110 in the coupling 100 is also different. Therefore, it is necessary to use anti-rotation parts 2 of different sizes to connect the first fastener 110 and the semi-circular ring part 1. The anti-rotation parts 2 are detachable from the semi-circular ring part 1, which makes it convenient to use anti-rotation parts 2 of different sizes to connect the coupling 100 and the semi-circular ring part 1.

[0035] like Figure 2 As shown, for easy mounting on the outside of the coupling 100, the ends of two adjacent semicircular rings 1 that abut against each other extend outward in the radial direction to form a splice 11; The torque adjustment fixture also includes: Several third fasteners 5 are provided on the splicing part 11. Each of the two adjacent splicing parts 11 is provided with a fifth connecting hole 1101 adapted to the third fastener 5. The third fasteners 5 are sequentially inserted into the fifth connecting holes 1101 of the two adjacent splicing parts 11 to make the two adjacent semi-circular ring parts 1 abut against each other.

[0036] Specifically, the splicing part 11 of two adjacent semi-circular ring parts 1 is detachably connected by a third fastener 5 and can be fastened to the outside of the coupling 100 in a semi-circular manner.

[0037] In this application, the first fastener 110, the second fastener 4 and the third fastener 5 are all configured as bolts and nuts. The bolts and nuts mentioned here are only one implementation method and are not considered as a limitation on the technical solution. Correspondingly, the above-mentioned fasteners can also be implemented as pin structures that cooperate with positioning holes.

[0038] like Figure 2 As shown, specifically, in order to facilitate torque adjustment after the coupling 100 is locked, at least two semi-circular rings 1 extend outward from the side away from each other to form several hook parts 12. Each hook part 12 is provided with a hook hole 1201 for connecting to one end of the flexible connector 3.

[0039] Since one end of the flexible connector 3 is connected to the semi-circular ring 1 through the mounting hole 1201, and the other end of the flexible connector 3 is connected to other fixed points, the flexible connector 3 can rotate inside the mounting hole 1201. The angle at which the flexible connector 3 pulls the semi-circular ring 1 can be adjusted arbitrarily, ensuring that the pulling force of the flexible connector 3 on the semi-circular ring 1 passes through the center of the semi-circular ring 1, and ensuring that the flexible connector 3 can stably lock the torque of the coupling 100.

[0040] Specifically, the length of the flexible connector 3 is adjustable in order to quickly fix the torque of the coupling 100.

[0041] When the flexible connector 3 is used to lock the torque of the coupling 100, by changing the length of the flexible connector 3 itself, the flexible connector 3 can be quickly tensioned, so that the semi-circular ring 1 is connected to the fixed part, thereby quickly locking the torque of the coupling 100.

[0042] Several connecting parts 12 are circumferentially distributed on the circumferential side surfaces of at least two semi-circular ring parts 1.

[0043] Multiple hook parts 12 are distributed around the semi-circular ring 1, and the semi-circular ring 1 can be pulled from different directions by multiple flexible connectors 3 to ensure that the coupling 100 is stably locked.

[0044] Specifically, the flexible connector 3 is a manual or electric hoist sling. The manual or electric hoist sling can be quickly hooked into the hook hole 1201, and its length can be quickly adjusted so that the coupling 100 can be quickly locked.

[0045] It should be noted that when the torque inside the coupling 100 is released, and because the flexible connector 3 is a manual or electric hoist sling, and the hoist sling is hooked into the hooking hole 1201, the position of the hook relative to the hooking hole 1201 can be adjusted arbitrarily. Therefore, in the synchronous shaft system, if the coupling 100 needs to rotate slightly, the position of the hook on the hooking hole 1201 can be changed, and the direction of the hoist sling's traction on the hooking hole 1201 can be changed, causing the coupling 100 to rotate. This better resists or adjusts the torque in the synchronous shaft system, facilitating the disassembly or installation of the internally connected components of the coupling 100.

[0046] The working principle of this torque adjustment tool is to separate two adjacent semi-circular ring parts 1. The semi-circular ring parts 1 can be radially fitted from the coupling 100 and connected to the coupling 100 and the semi-circular ring parts 1 by the anti-rotation part 2. After the semi-circular ring parts 1 are connected to the coupling 100, at least two semi-circular ring parts 1 are fixed from at least two directions by the flexible connecting part 3, so that the flexible connecting part 3 can lock the torque of the coupling 100 through the two semi-circular ring parts 1.

[0047] like Figure 3 As shown, on the other hand, the present invention also provides a synchronous shaft system, including: the aforementioned torque adjustment fixture, a plurality of drive components 200, a plurality of couplings 100, and a plurality of reversing transmission components 300, wherein the plurality of couplings 100 and the plurality of reversing transmission components 300 are used to drive the plurality of drive components 200, and the torque adjustment fixture is sleeved around the couplings 100.

[0048] When parts need to be replaced, a torque adjustment fixture is used to lock the torque of the coupling 100 by wrapping around it. This facilitates the replacement of parts and prevents the torque inside the synchronous shaft system from being released outward, ensuring that the synchronous shaft system as a whole is in normal working condition.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
