Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] The following reference Figure 1 and Figure 2 This application describes the cylinder liner installation tool in the embodiments.

[0023] according to Figure 1 and Figure 2As shown, an embodiment of the cylinder liner installation tool of this application includes a support frame 3, an upper plate 4, a lifting ring 51, a lifting ring sleeve 52, a jack 6, a lower plate 7, and a connecting rod 81. The cylinder liner 2 is installed in the mounting groove 11 of the machine body 1. The support frame 3 is installed above the machine body 1 and fixed in the fixing groove 12. The support frame 3 is used to bear the pressure during the downward installation of the cylinder liner 2. The upper plate 4 is installed on the upper end of the cylinder liner 2, and the bottom surface of the upper plate 4 is in contact with the upper end surface of the cylinder liner 2. This is used to evenly transmit pressure during the downward pressing process and prevent local deformation of the upper end surface of the cylinder liner 2. The lifting ring 51 is installed on the upper side of the upper plate 4. The lifting ring sleeve 52 is sleeved on the outside of the lifting ring 51 and connected to the upper plate 4. The lifting ring 51 is used as a lifting force transmission component when the cylinder liner 2 is lifted, and the lifting ring sleeve 52 is used to protect the lifting ring 51 when the cylinder liner 2 is pressed down, preventing deformation and damage to the lifting ring 51. One end of the jack 6 is connected to the upper side of the lifting eyelet 52, and the other end of the jack 6 is connected to the support frame 3. The lower plate 7 is installed at the lower end of the cylinder liner 2 to support it during lifting. The connecting rod 81 extends longitudinally through the cylinder liner 2; one end of the connecting rod 81 is connected to the upper plate 4, and the other end is connected to the lower plate 7, so that the upper plate 4 and the lower plate 7 abut against the upper and lower ends of the cylinder liner 2 respectively for force transmission. In use: When the cylinder liner 2 is being pressed down for installation, the user drives the jack 6, which abuts against the lower side of the support frame 3, causing the jack 6 to output downward pressure. The pressure generated by the jack 6 is transmitted to the upper plate 4 through the lifting eyelet 52, and then to the upper end of the cylinder liner 2, thereby pressing the cylinder liner 2 evenly into the mounting groove 11 of the machine body 1. After the cylinder liner 2 is fully pressed into the predetermined position, the pressure of the jack 6 is released, and the installation tools are removed.

[0024] When the cylinder liner 2 is lifted, the jack 6 is removed or the lower end of the jack 6 is raised to the highest point. The external drive mechanism is connected to the lifting ring 51 to provide an upward pulling force to the lifting ring 51. The pulling force can be transmitted through the upper plate 4 to the connecting rod 81, and then through the connecting rod 81 to the lower plate 7. Thus, the lower plate 7 supports the lower part of the cylinder liner 2 during the lifting process, providing upward power to the cylinder liner 2 and lifting it.

[0025] The cylinder liner installation tool of this application is easy to operate and can be used independently by one person. Simply driving the jack 6 to generate downward pressure allows the cylinder liner 2 to be smoothly pressed down axially; and simply connecting the external drive mechanism to the lifting ring 51 allows the cylinder liner 2 to be stably lifted. The installation process can be completed by a single person, effectively improving production efficiency. The cylinder liner installation tool of this application can both press down and lift the cylinder liner 2, achieving multi-functional use of a single tool.

[0026] In some embodiments, the connecting rod 81 can be directly connected to the lifting ring 51 to facilitate force transmission during the lifting of the cylinder liner 2.

[0027] In some embodiments, both the upper plate 4 and the lower plate 7 are provided with an inner protrusion (not shown in the figure). The inner protrusion is embedded in the cylinder liner 2 to prevent the upper plate 4 from moving laterally relative to the cylinder liner 2 during the pressing down of the cylinder liner 2; and to prevent the lower plate 7 from moving laterally relative to the cylinder liner 2 during the lifting of the cylinder liner 2, which would cause uneven force and damage to the cylinder liner 2.

[0028] In some embodiments, the cylinder liner 2, the lifting ring sleeve 52, and the upper plate 4 are all circular to maintain coaxial force distribution.

[0029] according to Figure 2 As shown, in one embodiment of this application, the lifting ring sleeve 52 is detachably connected to the upper plate 4.

[0030] In one embodiment of this application, the upper plate 4 is provided with a positioning groove 41, and the lifting ring sleeve 52 is provided with a positioning part 521 that cooperates with the positioning groove 41. The lifting ring sleeve 52 can be directly placed on the upper side of the upper plate 4. During the pressing down of the cylinder liner 2, the positioning part 521 and the positioning groove 41 form a limiting fit, thereby preventing the lifting ring sleeve 52 from rotating or shifting laterally when subjected to axial force, and ensuring a coaxial state.

[0031] In some other embodiments, the lifting eyelet 52 can also be detachably connected to the upper plate 4 by means of bolts 312 or pins.

[0032] This application uses a detachable connection between the lifting eye sleeve 52 and the upper plate 4 to ensure that the upper plate 4 is under stable force during the downward pressing of the lifting eye sleeve 52. This allows the downward pressure of the jack 6 to be transmitted to the upper end face of the cylinder liner 2 through the lifting eye sleeve 52, the lifting eye 51 and the upper plate 4 in the same vertical direction, avoiding eccentric force that could damage the cylinder liner 2. It also avoids the lifting eye sleeve 52 obstructing the lifting eye 51 when the cylinder liner 2 needs to be lifted.

[0033] according to Figure 1 and Figure 2 As shown, in one embodiment of this application, the lifting ring 51 is fixedly connected to the upper plate 4, and the lifting ring sleeve 52 is provided with a first through hole, which passes through the lifting hole of the lifting ring 51 to form a hole channel.

[0034] When the cylinder liner 2 is lifted, there is no need to remove the lifting ring sleeve 52. The lifting device of the external drive mechanism (such as a hook or wire rope) can pass through the first through hole of the lifting ring sleeve 52 and the lifting hole of the lifting ring 51 in sequence, thereby driving the cylinder liner 2 to be lifted and moved.

[0035] In some embodiments, the hole wall of the lifting ring sleeve 52 may be provided with a thickened or reinforced structure to enhance the stress strength of the hole channel.

[0036] The cylinder liner installation tool of this application eliminates the need for operators to repeatedly disassemble and assemble the lifting ring sleeve 52 or lifting ring 51, simplifying the operation process and further improving work efficiency and production efficiency.

[0037] according to Figure 1 and Figure 2 As shown, in one embodiment of this application, the cylinder liner installation tool further includes a threaded connector 82. The upper plate 4 has an installation hole at its center. The threaded connector 82 is fixedly installed in the installation hole. The threaded connector 82 has a threaded hole. The first end of the connecting rod 81 has a thread that mates with the threaded hole. The first end of the connecting rod 81 is connected to the upper plate 4 through the threaded connector 82.

[0038] according to Figure 1 As shown, in one embodiment of this application, the cylinder liner installation tool further includes a fixing component 91, which is connected to a connecting rod 81. A lower plate 7 is installed between the fixing component 91 and the cylinder liner 2. The fixing component 91 is configured to abut against the lower plate 7 so that the lower plate 7 abuts against the lower end face of the cylinder liner 2, forming a stable clamping structure.

[0039] according to Figure 1 As shown, in one embodiment of this application, the fixing component 91 is configured as a first nut 92, and the second end of the connecting rod 81 is provided with a thread that engages with the first nut 92.

[0040] During the assembly process of the cylinder liner installation tool, firstly, the connecting rod 81 is passed through the cylinder liner 2 from bottom to top. The first threaded end of the connecting rod 81 is screwed into the threaded connector 82 below the upper plate 4 and tightened to secure it. Then, the lower plate 7 is connected to the second end of the connecting rod 81. The lower plate 7 is secured by the fixing component 91 or by tightening the first nut 92. The upper and lower plates 7 are in close contact with both ends of the cylinder liner 2, forming a stable clamping state.

[0041] The cylinder liner installation tool of this application adjustably connects the connecting rod 81 to the upper plate 4 via a threaded connector 82, and adjustably connects the connecting rod 81 to the lower plate 7 via a first nut 92 and the lower end face of the cylinder liner 2. This allows for installation of cylinder liners 2 at different heights, increasing the practicality and versatility of the cylinder liner installation tool. Furthermore, the cylinder liner 2 can be locked and released simply by tightening or loosening the threads, without the need for additional tools. This facilitates quick installation or disassembly by a single person, further improving production efficiency.

[0042] In some embodiments, the connecting rod 81 may be configured as a threaded rod.

[0043] In some embodiments, an anti-loosening washer may be fitted on the side of the first nut 92 away from the lower plate 7, thereby enhancing the stability of the locking and preventing the nut from loosening due to vibration during the installation of the cylinder liner 2.

[0044] according to Figure 1 As shown, in one embodiment of this application, the support frame 3 includes a fixing component 31 and a supporting member 32. One end of the fixing component 31 is connected to the machine body 1, and the fixing component 31 is used to support the weight of the entire cylinder liner installation tool and the reaction force generated by the downward pressure of the jack 6. The supporting member 32 is connected to the other end of the fixing component 31. The supporting member 32 is horizontally arranged to form a transverse load-bearing structure, which is used to abut against the jack 6, thereby forming a stable support frame 3 structure. The other end of the jack 6 is connected to the lower side of the supporting member 32.

[0045] In some embodiments, the lower side of the support member 32 may be provided with a jack 6 positioning groove 41 to prevent the jack 6 from sliding or shifting when subjected to force, and to ensure that the downward pressure is transmitted in the vertical direction.

[0046] according to Figure 1 As shown, in one embodiment of this application, the fixing component 31 includes two fixing rods 311, the supporting component 32 is configured as a top bar 321, one end of the fixing rod 311 is installed in the fixing groove 12 of the body 1, the top bar 321 is connected to the other end of the fixing rod 311, and both ends of the top bar 321 are respectively connected to the two fixing rods 311.

[0047] In some other embodiments, the fixing component 31 may also be configured as a ring support frame 3, which is sleeved on the outside of the cylinder liner 2.

[0048] according to Figure 1 As shown, in one embodiment of this application, the fixing component 31 further includes a second nut 313, the fixing rod 311 is configured as a bolt 312, the top bar 321 is provided with a second through hole 322, the bolt 312 passes through the second through hole 322 and the second nut 313, the second nut 313 is installed on the upper side of the top bar 321, and the second nut 313 is configured to restrict the movement of the top bar 321.

[0049] After assembling the lifting eyelet 52 and the jack 6, first insert the lower ends of the two bolts 312 into and fix them in the fixing groove 12 of the machine body 1. Then, place the top bar 321 above the two bolts 312, so that the bolts 312 pass through the second through hole 322 of the top bar 321. Next, screw the second nut 313 onto the upper end of the bolts 312 and tighten it evenly so that both ends of the top bar 321 are pressed and fixed.

[0050] When the jack 6 generates pressure during downward pressing, the reaction force is transmitted to the top bar 321, and then to the machine body 1 through the constraint of the two bolts 312 and the second nut 313. The second nut 313 exerts a vertical pressing force on the top bar 321, keeping the top bar 321 in a fixed position during the force process, preventing upward, downward, or lateral displacement.

[0051] In some embodiments, the fixing rod 311 can also be configured as a screw. After assembling the lifting eyelet 52 and the jack 6, first insert and fix the lower ends of the two screws into the fixing groove 12 of the machine body 1, then place the top bar 321 above the two screws, so that the screws pass through the second through hole 322 of the top bar 321. Next, screw the second nut 313 onto the upper end of the screw and tighten it evenly, so that both ends of the top bar 321 are pressed and fixed. When the jack 6 generates top pressure when pressing down, the reaction force is transmitted to the top bar 321, and then transmitted to the machine body 1 through the constraint of the two screws and the second nut 313. When jack 6 reaches its maximum stroke but cylinder liner 2 has not yet been fully pressed down, jack 6 can be returned to its initial state, keeping the lower end of jack 6 unchanged while the upper end moves down. The top bar 321 then moves down and the second nut 313 is tightened so that the top bar 321 re-engages jack 6. Jack 6 is then driven to press down cylinder liner 2 until installation is complete.

[0052] In some embodiments, the fixing groove 12 is provided with threads, and the mounting bracket is detachably connected by the fixing rod 311 engaging with the threads in the fixing groove 12.
