[0026] like Figure 1As shown, the utility model discloses an engine cylinder block hoist, including a mounting plate 1, a lifting ring assembly, a control assembly, a guide rail assembly and two hook bodies. Among them, an adjustment hole is provided on the mounting plate 1, and the adjustment hole is in a long strip shape to facilitate the movement of the hook body, and the length of the adjustment hole is adapted to the movement displacement range of the two hook bodies. There can be one adjustment hole to satisfy both hook bodies at the same time; or two adjustment holes can be provided, each corresponding to a hook body. The lifting ring assembly is fixed on the mounting plate 1 to realize the lifting of the entire hoist. The guide rail assembly includes a guide rail 31 disposed at the adjustment hole and a first limit block 32 disposed at the end of the guide rail, wherein two first limit blocks are provided, respectively provided at both ends of the adjustment hole to realize the limitation of the relative maximum displacement of the slider. The control assembly includes two sliders 41 provided on the guide rail 31 and a control member 42 for controlling the slider 41 to move along the guide rail 31 in a direction away from or close to each other. There are two hook bodies and they are respectively arranged on both sides of the mounting plate 1 with the lifting ring assembly. The hook body includes a connecting rod 51 with one end fixed to the slider 41 and a hook portion 52 connected to the other end of the connecting rod 51. The hook portions 52 of the two hook bodies are respectively arranged on the sides of the two connecting rods 51 facing away from each other.

[0027] With the above structure, the two hooks are respectively fixed on the two sliders. When the control member controls the slider 41 to move toward each other along the guide rail 31, the two hooks close together, and the sling can be installed. After the sling is installed in place, when the control member controls the slider 41 to move away from each other along the guide rail 31, the two hooks are stuck in the locking grooves in the cylinder body to lock the cylinder body. At this time, the cylinder body can be hoisted. After the hoisting is completed, when the control member controls the slider 41 to move toward each other along the guide rail 31, the two hooks close together, the sling is taken out, and the hoisting is completed.

[0028] The above structure can be used to lock the cylinder body from inside the cylinder body and realize lifting. It is particularly suitable when the outer diameter of the cylinder body is large, such as Figure 3 The cylinder body 7 structure shown.

[0029] In order to improve the structural stability of the sling, preferably, the connecting rod 51 and the hook 52 are an integrated structure.

[0030] The guide rail can be directly fixed on both ends of the adjustment hole of the mounting plate 1, or directly fixed on the first limit blocks at both ends, and the first limit blocks are fixed on both ends of the adjustment hole of the mounting plate 1. The fixing method of the guide rail is not limited.

[0031] There are many ways to implement the lifting ring assembly. For example, lifting rings can be set on the four corners of the mounting plate 1, and the lifting rings on the four corners can be connected by lifting ropes to achieve lifting. Figure 1 As shown, the lifting ring assembly includes a lifting ring 21 and a connecting piece 22 for connecting the lifting ring 21 and the mounting plate 1. Lifting is achieved directly using a lifting ring.

[0032] With the existing structure, when the finished cylinder body is hoisted, the hoist often scratches the cylinder bore and the finely processed surface of the top surface of the cylinder body, resulting in the scrapping of the engine cylinder body, which brings high quality losses to the enterprise. In this regard, in order to achieve cylinder body protection, a protective layer 11 is fixed on one side of the mounting plate 1, and the protective layer 11 is arranged on one side of the hook body. The protective layer 11 is a nylon plate, a rubber plate or a flexible film. The protective layer is used to protect the cylinder body, prevent the top surface of the hoisted cylinder body from being scratched, and reduce the quality loss of the enterprise.

[0033] Specifically, the protective layer 11 can be fixed on the mounting plate 1 by bonding, or fixed on the mounting plate 1 by bolts.

[0034] In order to facilitate the installation of the sling and prevent the hook 52 from scratching the cylinder hole during the installation process, the installation plate 1 is fixed with a guide structure 61 to achieve guidance during installation. The guide structure is provided with a guide groove 62 for guiding the movement of the connecting rod 51. The depth of the guide groove 62 is greater than or equal to the length of the hook 52, so that the hook 52 can be hidden in the guide groove 62 during the installation process to protect the cylinder hole.

[0035] The guide structure 61 is used to guide the installation, and it can be implemented by various structures. Preferably, the guide structure is configured to be columnar. The guide structure 61 can be one or two. Figure 1 As shown, there are two examples of the guide structure 61 .

[0036] The guide structure 61 includes a guide section and a positioning section connected to each other. One end of the positioning section is fixed on the mounting plate 1. The diameter of the guide section gradually increases from the free end to the end connected to the positioning section. During installation, the guide section is placed at the bottom end and the positioning section is placed at the top end. The width of the positioning section is adapted to the cylinder hole of the cylinder body so that the hook body can be engaged with the locking groove.

[0037] For example, Figure 1 As shown, there are two guide sections and one positioning section.

[0038] Furthermore, in order to protect the cylinder hole, the guide structure 61 is a flexible guide structure, which can be made of rubber, nylon or flexible plastic.

[0039] In order to limit the movement of the slider, a second limit block 33 for limiting the displacement of the slider 41 is provided in the middle of the guide rail 31. The second limit block 33 is provided in the middle of the guide rail to limit the relative minimum distance between the two hooks. Specifically, the second limit block 33 can be directly fixed on the guide rail 31 or on the mounting plate 1.

[0040] The control member 42 realizes the sliding control of the two sliders, and there are many ways to achieve it, such as using existing screws and other structures. In order to facilitate control, the utility model discloses an implementation method, referring to Figure 4 , including an adjusting rod 421, a fixing block 422, an operating member 423, and a connecting piece 424. One of the two sliders is a first slider, and the other is a second slider. The first slider is fixed on the adjusting rod 421; the second slider is installed on the adjusting rod 421 through a fixing hole, that is, the second slider and the adjusting rod are slidably connected. The fixing block 422 is fixed on the second slider. The operating member 423 is "L" shaped and one end is rotatably connected to one end of the adjusting rod 421. The two ends of the connecting piece 424 are rotatably connected to the operating member 423 and the fixing block 422 respectively.

[0041] For easy operation, a handle 425 for operation is provided at one end of the operating member 423 .

[0042] With the above structure, the distance between the first slider and the second slider can be adjusted by directly controlling the rotation of the handle, thereby achieving the locking and unlocking control of the spreader. Figure 4 For example, when the handle 425 is pulled downward, the "L"-shaped control member 423 drives the adjustment rod 421 to move upward, the two sliders approach each other, and the sling is unlocked. When the handle 425 is pulled upward again, the "L"-shaped control member 423 drives the adjustment rod 421 to move downward, the two sliders move away from each other, and the sling is locked.

[0043] The above structure can realize the rapid lifting of the engine block, which is safe and reliable without scratching the machined surface of the engine, thereby improving the efficiency and quality of the engine block lifting, while protecting the safety of surrounding tooling equipment and the personal safety of operators.

[0044] With the above structure, the guide rail assembly and the control assembly are used to realize the movement control of the two hook bodies. The control member controls the slider 41 to move toward each other along the guide rail 31 and hides the hook 52 in the guide groove 62, so that the sling can be installed. After the sling is installed in place, the control member controls the slider 41 to move away from each other along the guide rail 31 until the slider abuts against the first limit block 32. Figure 1 As shown, at this time, the two hooks are stuck in the locking grooves in the cylinder body, and the cylinder body can be hoisted.

[0045] By adopting the above structure, the guide structure is used for installation guidance and positioning of the hoisting device, so that the rapid positioning of the hoisting of the engine cylinder body is realized, and at the same time the stability and safety of the hoisting are ensured.

[0046] By adopting the above structure, a protective layer 11 is arranged under the mounting plate 1 to prevent scratches on the top surface of the hoisted cylinder body, thereby reducing the quality loss of the enterprise.

[0047] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
