DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0042] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] In the description of the present invention, it should be noted that the terms used, such as "first" and "second", are only used to distinguish the expressions, rather than to indicate or imply the difference in importance or order. The use of the above terms is only to facilitate a clear and simple description of the technical solution of the present invention, and cannot be understood as a limitation of the present invention.

[0044] A commonly used existing manual disassembly method is first described below, so that relevant technical personnel can understand why manual disassembly is likely to cause damage to the coupling workpiece structure.

[0045] Generally, the flange can be clamped with a clamping tool first, and then the shaft can be manually pulled out with the help of the clamping tool. However, during the pulling out process, the flange needs to be firmly clamped with a clamping tool, which may cause structural damage to the flange. At the same time, it is difficult to keep the shaft in a horizontal state during the pulling out process, and the operation is difficult. In addition, if the shaft deviates to a certain extent during the pulling out process, structural damage will be caused to the connection between the shaft or the flange.

[0046] In view of this, the present invention provides a new solution, that is, the disassembly tool of the present invention. Through the disassembly tool of the present invention, not only can the coupling be disassembled very conveniently and quickly, but also structural damage to the shaft or flange can be effectively avoided.

[0047] The technical solution of the present invention is described in detail below with reference to the accompanying drawings.

[0048] Example 1

[0049] like Figures 1 to 10 As shown, this embodiment provides a disassembly tool 100 for disassembling a coupling workpiece 200, comprising a mounting frame 1, a first driving member 21, a second driving member 22, a first disassembly arm 31, a second disassembly arm 32, a first support block 41, and a second support block 42. The first driving member 21 is mounted on the mounting frame 1, and the output end of the first driving member 21 is used to abut against the shaft 201 of the coupling workpiece 200, so that the output end of the first driving member 21 can abut against the shaft 201 of the coupling workpiece 200 and push the shaft 201 of the coupling workpiece 200 along the first direction. The first disassembly arm 31 and the second disassembly arm 32 are used to be arranged on opposite sides of the coupling workpiece 200, the second driving member 22 is installed on the mounting frame 1, the second driving member 22 includes a driving body 221 and an output rod body 222 connected to the driving body 221, one end of the first disassembly arm 31 is connected to the driving body 221, the other end of the first disassembly arm 31 is connected to the first support block 41, one end of the second disassembly arm 32 is connected to the output rod body 222, and the other end of the second disassembly arm 32 is connected to the second support block 42, the first support block 41 and the second support block 42 are respectively used to abut against the flange 202 of the coupling workpiece 200, so that the first support block 41 and the second support block 42 can abut against the flange 202 of the coupling workpiece 200 respectively along the second direction. The first direction and the second direction are configured to be collinear with the axial direction of the coupling workpiece 200, and the first direction and the second direction are opposite directions.

[0050] Through the above technical scheme, on the one hand, the disassembly tool 100 of the present invention can quickly and conveniently complete the disassembly of the coupling workpiece 200, which can effectively improve the disassembly efficiency and reduce the disassembly difficulty, thereby effectively shortening the maintenance time of equipment such as water pumps and oil pumps and improving the maintenance efficiency of the equipment.

[0051] On the other hand, during the process of disassembling the coupling, the disassembly tool 100 of the present invention can make the shaft smoothly and reliably disengage from the flange 202 along its axial direction, thereby avoiding the possible deviation of the shaft 201 during the disassembly process, thereby effectively avoiding the problem of the coupling workpiece 200 being damaged due to the deviation of the shaft 201. At the same time, during the disassembly process, the force transmission direction between the first support block 41, the second support block 42 and the flange 202 is along the axial direction of the flange 202. Therefore, during the entire disassembly process, structural damage to the flange 202 can be effectively avoided, thereby effectively avoiding waste of resources and asset loss.

[0052] To facilitate understanding by relevant technical personnel, the working principle / working process of the above technical solution is explained below.

[0053] When the coupling workpiece 200 needs to be disassembled, the coupling can be placed in a fixed position, and the output end of the first driving member 21 is aligned with the shaft 201 of the coupling workpiece 200 and abutted against it, so that the output end of the first driving member 21 can be moved in a first direction (the first direction is Figure 1 At the same time, by adjusting the second driving member 22, the first support block 41 and the second support block 42 are aligned with the flange 202 of the coupling workpiece 200 and abutted against it, so that the first support block 41 and the second support block 42 can provide a supporting force for the flange 202 in the second direction. In this way, the first driving member 21 can be started, so that the output end of the first driving member 21 pushes the shaft 201 along the first direction. Due to the obstruction of the first support block 41 and the second support block 42, the flange 202 will remain in place, so that the coupling workpiece 200 can be quickly and non-destructively disassembled.

[0054] In this embodiment, it should be noted that: first, in the present invention, the second driving member 22 is connected to the first support block 41 and the second support block 42 through the first disassembly arm 31 and the second disassembly arm 32, so that the relative distance between the first support block 41 and the second support block 42 can be adjusted, so as to effectively adapt to the disassembly needs of coupling workpieces 200 of different sizes, which is conducive to improving the versatility of the disassembly tool 100 of the present invention.

[0055] Second, the first support block 41 and the second support block 42 of the present invention may have a certain rotation angle, that is, the first support block 41 and the second support block 42 are rotatably connected to the first disassembly arm 31 and the second disassembly arm 32, respectively, so that they can be closely fitted to the surface of the flange 202 when adapting to the coupling workpiece 200 of different sizes.

[0056] Third, the present invention is provided with a first support block 41 and a second support block 42, which has two advantages. First, it can effectively ensure that a stable and reliable support force is provided for the flange 202. At the same time, the pressure on the flange 202 can be effectively distributed through the first support block 41 and the second support block 42, which is conducive to preventing the flange 202 from being damaged. Second, the first support block 41 and the second support block 42 located on both sides of the flange 202 can effectively ensure the position stability of the flange 202 during the process of the shaft being pushed by the first driving member 21, which is conducive to ensuring that the shaft can be relatively stably separated from the flange 202 along its axial direction, and further reducing the possibility of the shaft being offset.

[0057] Fourthly, it is understandable that the first driving member 21 and the second driving member 22 of the present invention may adopt a hydraulic driving device (see below) or a pneumatic driving device.

[0058] In one embodiment of the present invention, Figures 1 to 3 as well as Figure 6 and Figure 7 As shown, the first driving member 21 of the present invention may include a hydraulic pump 211, a multi-way control valve group 212, a main push cylinder 213 and a vertical lifting cylinder 214. The hydraulic pump 211 is connected to the main push cylinder 213 and the vertical lifting cylinder 214 respectively through the multi-way control valve group 212. The output end of the vertical lifting cylinder 214 is connected to the main push cylinder 213 to drive the main push cylinder 213 to move in the vertical direction. The output end of the main push cylinder 213 is used to abut against the shaft 201 of the coupling workpiece 200, so that the output end of the main push cylinder 213 can abut against the shaft of the coupling workpiece 200 and push the shaft 201 of the coupling workpiece 200 along the first direction.

[0059] In this embodiment, first, the first driving member 21 is configured as a hydraulic pushing device, which not only has the advantages of greater pushing force and high control accuracy, but also has better safety and stability, and can be well adapted to the disassembly operation of the coupling workpiece 200.

[0060] Second, by configuring the vertical lifting cylinder 214 in this way, the position of the main push cylinder 213 in the vertical direction can be effectively adjusted, so that it can be well adapted to coupling workpieces 200 of different placement positions and sizes, and can effectively improve the versatility of the disassembly tool 100 of the present invention.

[0061] Third, the present invention connects the main push cylinder 213 and the vertical lift cylinder 214 to the same hydraulic pump 211 through the multi-way control valve group 212, which can not only achieve the working reliability of the main push cylinder 213 and the vertical lift cylinder 214, but also effectively reduce the manufacturing cost and space occupancy of the disassembly tool 100 of the present invention, and can be well adapted to most maintenance workshops.

[0062] In one embodiment of the present invention, Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the first disassembly arm 31 and the second disassembly arm 32 of the present invention can be arranged at intervals in the horizontal direction, the second driving member 22 is configured as a horizontal extension cylinder, the hydraulic pump 211 is connected to the horizontal extension cylinder through the multi-way control valve group 212, the fixed end of the horizontal extension cylinder is installed at an end of the first disassembly arm 31 away from the first support block 41, the output end of the horizontal extension cylinder is connected to an end of the second disassembly arm 32 away from the second support block 42, and the middle part of the first disassembly arm 31 and the middle part of the second disassembly arm 32 are respectively hinged on the mounting frame 1.

[0063] In this way, the first support block 41 installed on the first disassembly arm 31 and the second support block 42 installed on the second disassembly arm 32 can be effectively attached to the opposite sides of the flange 202, can effectively maintain the position stability and force balance of the flange 202, and will not interfere with the mutual separation process of the shaft and the flange 202, and can ensure that the shaft is stably and smoothly separated from the flange 202 along its axial direction during the disassembly process.

[0064] At the same time, the second driving member 22 is configured as a horizontal extension cylinder and is connected to the hydraulic pump 211 through a multi-way control valve group 212. It can not only achieve the working reliability of the horizontal extension cylinder, but also effectively reduce the manufacturing cost and space occupancy of the disassembly tool 100 of the present invention, and can be well adapted to most maintenance workshops.

[0065] In addition, since the horizontal extension cylinder is connected to one end of the first disassembly arm 31 and the second disassembly arm 32 (the end away from the first support block 41 and the second support block 42), and the middle parts of the first disassembly arm 31 and the second disassembly arm 32 are respectively hinged on the mounting frame 1 (that is, the first disassembly arm 31 and the second disassembly arm 32 can respectively rotate a certain angle relative to the hinge between them and the mounting frame 1), in this way, not only can the position stability of the first disassembly arm 31 and the second disassembly arm 32 during the disassembly process be effectively maintained, but also the relative rotation angles of the first disassembly arm 31 and the second disassembly arm 32 can be effectively ensured to be consistent, thereby ensuring that the first support block 41 and the second support block 42 can be relatively attached to the two sides of the flange 202, thereby ensuring the posture and position stability of the flange 202 during the disassembly process.

[0066] In one embodiment of the present invention, Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the disassembly tool 100 of the present invention may also include a retractable cylinder-balanced telescopic bracket 5, which is arranged between the horizontal extension cylinder and the main push cylinder 213, and the two ends of the cylinder-balanced telescopic bracket 5 are respectively hinged to the first disassembly arm 31 and the second disassembly arm 32; wherein the middle part of the cylinder-balanced telescopic bracket 5 is hinged to the main push cylinder 213.

[0067] In this way, on the one hand, the retractable cylinder balanced retractable bracket 5 is connected between the first disassembly arm 31 and the second disassembly arm 32, which can effectively ensure the stability of the relative rotation angle of the first disassembly arm 31 and the second disassembly arm 32, and at the same time, can also effectively improve the position stability of the first disassembly arm 31 and the second disassembly arm 32 during the disassembly process.

[0068] On the other hand, the cylinder balancing telescopic bracket 5 is also hinged to the main push cylinder 213 , which can effectively further improve the position and posture stability of the main push cylinder 213 and ensure the alignment degree between the main push cylinder 213 and the shaft 201 of the coupling workpiece 200 .

[0069] In one embodiment of the present invention, Figure 1 As shown, the mounting frame 1 of the present invention can be formed into a U-shaped structure, and the mounting frame 1 includes a bottom plate 11 and a top plate 12 that are relatively arranged, and a vertical plate 13 connected between the bottom plate 11 and the top plate 12; wherein, the hydraulic pump 211 is arranged on the side of the top plate 12 close to the vertical plate 13, and the multi-way control valve group 212 and the vertical lifting cylinder 214 are respectively arranged on the side of the top plate 12 away from the vertical plate 13.

[0070] In this way, through the installation frame 1 set up in this way, not only can the hydraulic pump 211, the multi-way control valve group 212 and the vertical lifting cylinder 214 be effectively and reliably installed, but it is also beneficial to reduce the space occupied by the installation frame 1 and improve the structural simplicity of the installation frame 1.

[0071] In one embodiment of the present invention, Figure 1 As shown, the mounting frame 1 of the present invention may further include a plurality of universal wheels 14, which are respectively arranged on a side of the bottom plate 11 away from the vertical plate 13. Thus, by means of the universal wheels 14 arranged in this way, the position of the mounting frame 1 can be quickly and conveniently adjusted, thereby enabling the disassembly tool 100 of the present invention to be well adapted to the coupling workpiece 200 placed at any position, which is conducive to further improving the versatility of the disassembly tool 100 of the present invention.

[0072] In one embodiment of the present invention, Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, the disassembly tool 100 of the present invention may further include two mounting plates 6, one end of the two mounting plates 6 is respectively connected to the first disassembly arm 31 and the second disassembly arm 32, and the other end of the two mounting plates 6 is respectively connected to the first support block 41 and the second support block 42.

[0073] In this way, by means of the mounting plate 6 thus arranged, on the basis of being able to realize reliable installation of the first support block 41 and the second support block 42, it is also beneficial to ensure that there is a sufficient spacing between the first disassembly arm 31 and the second disassembly arm 32 to accommodate the coupling workpiece 200, and to ensure that during the disassembly process, the shaft of the coupling workpiece 200 has sufficient disassembly space.

[0074] In one embodiment of the present invention, Figure 8 and Fig. 9 As shown, the mounting plate 6 of the present invention may include two side plates 61 arranged opposite to each other and a connecting plate 62 connected between the two side plates 61, the side plates 61 are formed into a plate-like structure with a right-angled trapezoidal cross-section, the side plates 61 corresponding to the side of the long bottom side of the right-angled trapezoid are connected to the first disassembly arm 31 or the second disassembly arm 32, the side plates 61 corresponding to the side of the right-angled waist side of the right-angled trapezoid are connected to the connecting plate 62, and the connecting plate 62 is used to install the first support block 41 or the second support block 42.

[0075] Thus, on one hand, the side plate 61 is configured as a plate-like structure with a right-angle trapezoidal cross section, which can not only stably and reliably install the first support block 41 or the second support block 42, but also helps to reduce the manufacturing cost of the side plate 61. On the other hand, the connecting plate 62 configured in this way has a larger installation space, so that the first support block 41 and the second support block 42 can be well installed.

[0076] In one embodiment of the present invention, Figures 8 to 10 As shown, the first support block 41 and the second support block 42 of the present invention can be formed into a symmetrical structure; the first support block 41 can include an attached plate body 411, a connecting rod 412 and two locking nuts 413, the attached plate body 411 is formed into an arc-shaped curved plate structure, the connecting rod 412 includes a coaxially connected connecting section 4121 and a penetration section 4122, the connecting section 4121 is connected to the attached plate body 411 at one end away from the penetration section 4122, and the radial dimension of the connecting section 4121 gradually decreases in the direction from the attached plate body 411 to the penetration section 4122, and the penetration section 4122 is formed with an external thread that matches the locking nut 413; a penetration through hole 621 for the penetration section 4122 to penetrate is opened on the connecting plate 62, and two locking nuts 413 are threadedly connected to the penetration section 4122 and are located on both sides of the connecting plate 62 so that the first support block 41 can be detachably mounted on the connecting plate 62.

[0077] Thus, in this embodiment, first, relative to the technical solution described above in which the first support block 41 and the second support block 42 can have a certain rotation angle, the first support block 41 and the second support block 42 of this embodiment can be more securely installed on the first disassembly arm 31 and the second disassembly arm 32, and can effectively avoid the shaking of the first support block 41 and the second support block 42, and can effectively enhance the stable support of the first support block 41 and the second support block 42 for the flange 202.

[0078] Second, the arc-shaped curved plate structure of the attached plate body 411 can not only adapt well to the shape of the flange 202, but also effectively increase the contact area between the attached plate body 411 and the flange 202, reduce the relative pressure between the attached plate body 411 and the flange 202, further optimize the stress condition of the flange 202, and avoid damage to the flange 202 due to excessive stress.

[0079] Third, the two locking nuts 413 and the penetration section 4122 arranged in this way can stably and reliably install the connecting rod 412 on the connecting plate 62, and are easy to install and disassemble.
