[0023] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0024] like Figure 1-Figure 4As shown, a lifting tool for a cylinder liner 1 according to an embodiment of the utility model, the outer peripheral side wall of the cylinder liner 1 has a boss 11, including: a lifting ear 2, a rotating shaft 3 and two clamping assemblies 4; the rotating shaft 3 is arranged at one end of the lifting ear 2 in a first direction X, and the rotating shaft 3 extends along a second direction Y; the two clamping assemblies 4 are respectively arranged on both sides of the lifting ear 2 in a third direction Z, the clamping assembly 4 includes a lifting arm 41 and a clamping member 42, the lifting arm 41 includes a first extension portion 411 and a second extension portion 412, the clamping member 42 and the first extension portion 411 are arranged at one side of the second extension portion 412 at intervals along the length direction of the second extension portion 412, the first extension portion 411 is rotatably connected to the rotating shaft 3 at one end away from the second extension portion 412, and as the lifting arm 41 rotates, the clamping member 42 can abut against the bottom surface of the boss 11.

[0025] Based on the above scheme, the device clamps the cylinder liner 1 by rotating the two clamping components 4 around the rotating shaft 3, that is, the first extension part 411 rotates around the rotating shaft 3, driving the clamping part 42 arranged on the second extension part 412 to rotate, so that the clamping part 42 can abut against the bottom surface of the boss 11. When the cylinder liner 1 is lifted by the lifting ear 2, due to the weight of the cylinder liner 1 itself, the clamping part 42 can maintain the state of abutting against the bottom surface of the boss 11, and the lifting arm 41 can firmly lock the cylinder liner 1 inward, so as to realize a smooth and safe lifting process and avoid damage to the cylinder liner 1. In addition, the device has a simple structure and is easy to use. When in use, it only needs to control the lifting arm 41 to swing to complete the lifting process, which can improve the work efficiency of the lifting process.

[0026] like Figure 5 As shown, in order to ensure the stability of the lifting process, the clamping part 42 includes a clamping ring 421 and an abutting protrusion 422. The clamping ring 421 extends along the circumference of the boss 11, and the clamping ring 421 is arranged on the second extension portion 412. The abutting protrusion 422 is arranged on the side of the clamping ring 421 away from the second extension portion 412. With the rotation of the lifting arm 41, the abutting protrusion 422 can abut against the bottom surface of the boss 11. When the cylinder liner 1 is lifted by the lifting ear 2, due to the weight of the cylinder liner 1 itself, the clamping ring 421 will be locked inwardly and firmly on the outer peripheral side of the boss 11, and the abutting protrusion 422 can maintain the state of abutting against the bottom surface of the boss 11, thereby preventing the cylinder liner 1 from falling off from the clamping assembly 4 during the lifting process, thereby ensuring the stability of the lifting process.

[0027] like Figure 5 As shown, in order to further ensure the stability of the lifting process, the clamping part 42 includes a plurality of abutment protrusions 422, and the plurality of abutment protrusions 422 are evenly spaced along the extension direction of the clamping ring 421. When the clamping ring 421 firmly locks the outer peripheral side of the boss 11 inward, the plurality of abutment protrusions 422 can abut against the bottom surface of the boss 11, thereby improving the supporting strength of the boss 11, thereby avoiding misalignment of the boss 11 and the abutment protrusions 422 during the lifting process, causing the boss 11 to fall off from the clamping assembly 4.

[0028] Optionally, in order to improve the strength of the abutting protrusion 422 , the clamping member 42 further includes a washer, which is sleeved on the abutting protrusion 422 , and the abutting protrusion 422 is in indirect contact with the boss 11 through the washer.

[0029] Optionally, in order to prevent wear of the cylinder liner 1, the gasket is made of aluminum.

[0030] like Figure 3 and Figure 4 As shown, in order to ensure that the two clamping assemblies 4 are arranged evenly, the lifting ear 2 has a slot 21 at one end in the first direction X, and the slot 21 extends along the third direction Z and passes through the lifting ear 2. The lifting ear 2 also has a first mounting hole 22 and a second mounting hole 23 on both sides of the second direction Y. The first mounting hole 22, the slot 21 and the second mounting hole 23 are connected in sequence. The first extension portion 411 has a third mounting hole 4111 at one end away from the second extension portion 412, and the third mounting hole 4111 extends along the second direction Y and passes through the first extension portion 411. The rotating shaft 3 passes through the first mounting hole 22, the third mounting hole 4111 and the second mounting hole 23 in sequence to install the first extension portion 411 in the slot 21, and enable the first extension portion 411 to rotate around the rotating shaft 3. When the cylinder liner 1 is lifted by the lifting ear 2, the two clamping assemblies 4 can be symmetrically arranged on both sides of the lifting ear 2, and during the entire lifting process, the two clamping assemblies 4 are subjected to balanced force.

[0031] like Figure 4 As shown, in order to facilitate the control of the rotation of the boom 41, the boom 41 also has a third extension portion 413, one end of the third extension portion 413 is connected to an end of the first extension portion 411 away from the second extension portion 412, and the third extension portion 413 has the same extension direction as the first extension portion 411, and the rotation of the boom 41 is controlled by the third extension portion 413.

[0032] In some embodiments, when the device is in a natural state and the cylinder liner 1 is not hoisted, as the third extension portion 413 rotates, the third extension portion 413 can abut against the outer peripheral side of the lifting ear 2. Since the lifting ear 2 is provided, the clamping parts 42 of the two clamping assemblies 4 can be prevented from colliding with each other and causing damage.

[0033] like Figure 4 As shown, in order to ensure the stability of the lifting process, the extension direction of the first extension part 411 is approximately perpendicular to the extension direction of the second extension part 412, so that when the clamping part 42 abuts against the bottom surface of the boss 11, the first extension part 411 can be in an approximately parallel state with the clamping part 42, and then the second extension part 412 can better contact with the outer peripheral side surface of the boss 11 to firmly lock the outer peripheral side surface of the boss 11.

[0034] like Figure 4As shown, in order to facilitate removal, the hanging arm 41 further has a hanging portion 414, which is disposed on the top surface of the second extension portion 412, and has a hanging hole, which is used to remove the hanging arm 41.

[0035] Optionally, in order to extend the service life of the device, the clamping component 4 is made of stainless steel.

[0036] In summary, the embodiment of the utility model provides a lifting tool for the cylinder liner 1, which is compared with the prior art. The cylinder liner 1 is clamped by rotating two clamping components 4 around the rotating shaft 3, that is, the first extension part 411 rotates around the rotating shaft 3, driving the clamping part 42 arranged on the second extension part 412 to rotate, so that the clamping part 42 can abut against the bottom surface of the boss 11. When the cylinder liner 1 is lifted by the lifting ear 2, due to the weight of the cylinder liner 1 itself, the clamping part 42 can maintain the state of abutting against the bottom surface of the boss 11, and the lifting arm 41 can firmly lock the cylinder liner 1 inward, so as to realize a smooth and safe lifting process and avoid damage to the cylinder liner 1. In addition, the device is easy to use. When in use, it only needs to control the lifting arm 41 to swing to complete the lifting process, which can improve the work efficiency of the lifting process. In addition, the device has a simple structure, low manufacturing cost, and can also be processed using the original facilities of the factory.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
