In the absence of further restrictions, an element defined by the sentence "includes a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element.

[0025] See also Figure 1-6 , describe the embodiments of the present utility model in detail.

[0026] Example: Lifting device for quick lifting of cylinder liner, see Figure 1 , Figure 2As shown, it includes a semicircular ring clamp Ⅰ1 and a semicircular ring clamp Ⅱ2, both of which are semicircular ring structures, the left end of the semicircular ring clamp Ⅰ1 and the left end of the semicircular ring clamp Ⅱ2 are hinged together, the right end of the semicircular ring clamp Ⅰ1 and the right end of the semicircular ring clamp Ⅱ2 are connected by a side-pull toggle clamp 11, and a plurality of pads 5 are arranged on the inner surfaces of the semicircular ring clamp Ⅰ1 and the semicircular ring clamp Ⅱ2.

[0027] The process of hoisting the cylinder liner using this embodiment: refer to Figure 3 , Figure 4 As shown in the figure: when lifting the cylinder liner, the handle on the side-pull toggle clamp 11 is opened, the lifting device is put on the cylinder liner, and then the cylinder liner is locked by the handle on the side-pull toggle clamp 11, and then the cylinder liner is lifted by the eye bolt. The whole operation process is fast and convenient, and the clamping force acting on the cylinder liner can be controlled by adjusting the nut on the U-shaped tie rod bolt on the side-pull toggle clamp 11 to ensure that the clamping force does not damage the cylinder liner.

[0028] In this embodiment, one end of the semicircular ring clamp Ⅰ1 and the semicircular ring clamp Ⅱ2 are linked, and the other end can be opened by opening the handle on the side-pull toggle clamp 11, so that the sling can be quickly detached from the cylinder sleeve, which is convenient and quick to operate and improves work efficiency.

[0029] In a specific embodiment, the left end of the semicircular ring clamp I1 and the left end of the semicircular ring clamp II2 are both provided with a hinge seat, and the hinge seats at the left ends of the semicircular ring clamp I1 and the semicircular ring clamp II2 are connected together by a pin 3, and the end of the pin 3 is limited by a pin 4.

[0030] The above structure facilitates the quick and firm hinge connection of the left end of the semicircular clamp Ⅰ1 and the left end of the semicircular clamp Ⅱ2, and the pin and latch are common components in the connection structure and are easy to obtain, which reduces the manufacturing difficulty of the sling.

[0031] In a specific embodiment, each of the pads 5 is fixedly connected to the corresponding semicircular ring clamp Ⅰ1 or semicircular ring clamp Ⅱ2 through a pad fixing bolt 6, and the inner surface of the pad 5 is an arc surface for adapting to the outer circular surface of the cylinder liner.

[0032] Through the above structure, the pad is designed and manufactured using three-dimensional software, and its curvature completely complies with the outer diameter of the cylinder liner, and can fit tightly with the cylinder liner, so that the clamping force of the hanger on the cylinder liner is uniform.

[0033] Preferably, the pad 5 is made of copper, which is a relatively soft material and can produce a slight deformation under the clamping force, thereby ensuring that the force on each pad is as uniform as possible.

[0034] In a specific implementation, eye bolts 8 are fixed on the outer sides of the semicircular ring clamp Ⅰ1 and the semicircular ring clamp Ⅱ2.

[0035] The fixing method of the lifting eye bolt 8 is as follows: a lifting eye mounting seat 7 is provided on the outer side surface of the semicircular ring clamp Ⅰ1 and the semicircular ring clamp Ⅱ2, and the lifting eye mounting seat 7 is fixedly connected to the corresponding semicircular ring clamp Ⅰ1 and the semicircular ring clamp Ⅱ2 through the mounting seat bolt 9, and the lifting eye bolt 8 is threadedly screwed on the lifting eye mounting seat 7.

[0036] Through the above structure, the lifting rings are symmetrically arranged on both sides, which makes it easy to lift the parts.

[0037] In a specific embodiment, the side-pull elbow clamp 11 includes a clamp bracket 11-1, a clamp handle 11-2, a U-shaped pull rod bolt 11-3 and a hook 11-6. The right ends of the semicircular ring clamp Ⅰ1 and the semicircular ring clamp Ⅱ2 are both provided with mounting seats. The hook 11-6 is fixed to the mounting seat at the right end of the semicircular ring clamp Ⅰ1 by a fixing bolt 10. The clamp bracket 11-1 is fixed to the mounting seat at the right end of the semicircular ring clamp Ⅱ2 by a fixing bolt 10. The front part of the clamp handle 11-2 is hinged to the clamp bracket 11-1 through a connecting pin shaft. Pull rod connecting seats 11-4 are provided on both sides of the middle part of the clamp handle 11-2. Both ends of the U-shaped pull rod bolt 11-3 pass through the pull rod connecting seats 11-4 on both sides respectively and are limited by adjusting nuts 11-5.

[0038] The side-pull toggle clamp structure adopted above is clamped by the side-pull toggle clamp, and its clamping and disengaging operations are simple, the clamping force is up to 8.8KN, and the clamping is reliable and stable. The clamping force applied to the cylinder liner can be controlled by adjusting the screw-in length of the nut on the U-shaped tie rod bolt on the side-pull toggle clamp to ensure that the clamping force does not damage the cylinder liner.

[0039] When the hoist lifts the cylinder liner, the operation is simple, fast and convenient, which greatly improves the clamping efficiency. The clamping process will not cause unnecessary damage to the cylinder liner due to excessive clamping force. The hoist has a novel design concept and a simple structure, and can be quickly promoted to solve similar problems.
