Description

Technical Field

[0001] This utility model relates to the technical field of cylinder head processing and hoisting equipment, and in particular to a cylinder head hoisting device. Background Technology

[0002] The cylinder head is the cover of the engine and the component that seals the cylinder. It is generally made of cast iron or aluminum alloy. It serves as the mounting base for the valve mechanism, the sealing cover for the cylinder, and together with the inner surface of the cylinder and the top of the piston, it forms the combustion chamber. Its main function is to cool the engine.

[0003] Cylinder heads need to be handled and moved during processing, requiring lifting devices. Various lifting devices exist, such as the Chinese utility model patent CN219860116U, entitled "An Adjustable Hook and Cylinder Head Lifting Device." This patent includes a connecting frame with a fixed hook at one end and a movable hook slidably mounted at the other end. The movable hook corresponds to the fixed hook and is adapted to the mounting holes or lifting holes on the cylinder head. Both the movable and fixed hooks are equipped with elastic limiting mechanisms to impede the free movement of the cylinder head. These elastic limiting mechanisms include limiting blocks, which... The rotating shaft is rotatably installed in the mounting grooves provided on the movable and fixed hooks. A spring is compressed at the bottom of the limiting block, which is located in the mounting groove. Under the elastic action of the spring, the limiting block will limit the cylinder head and prevent it from falling off. In use, although the above structure can limit the cylinder head to a certain extent through the spring and the limiting block, the limiting effect on the cylinder head is limited because the size of the part of the limiting block protruding from the mounting groove is small. In addition, in order to facilitate the smooth insertion of the movable and fixed hooks into the mounting holes or lifting holes of the cylinder head, the elastic force of the spring is often designed to be small. Therefore, there is still a risk of the cylinder head falling off during use. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, this utility model provides a cylinder head lifting device, which solves the problem that the current lifting device only relies on springs and limit blocks to stop and limit the cylinder head, and there is a risk of the cylinder head falling off during use.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A cylinder head lifting device includes a lifting frame body, a lifting arm hinged to the top of the lifting frame body, a lifting cable connected to the lifting arm, the end of the lifting cable away from the lifting arm being wound around a winch of a winch, the winch being slidably mounted on a support frame, a stop frame movably mounted on the top of the lifting frame body near the lifting arm, the stop frame being hinged to the lifting arm via a connecting frame, an elastic stop component movably mounted on the end of the stop frame away from the connecting frame, the elastic stop component and the lifting frame body forming a space for limiting and fixing the cylinder head.

[0007] As an improved technical solution, the elastic barrier assembly includes a barrier sleeve, which is slidably fitted onto the barrier frame. The inner cavity of the barrier sleeve is provided with a spring, which is compressed between the barrier frame and the barrier sleeve.

[0008] As an improved technical solution, a limiting block is provided at one end of the barrier frame connected to the barrier sleeve, and the limiting block is slidably installed inside the barrier sleeve;

[0009] The barrier frame is provided with a first connecting ear at one end away from the limiting block, and the first connecting ear is hinged to the connecting frame.

[0010] As an improved technical solution, the connecting frame includes two connecting arms arranged opposite to each other, which are connected by a connecting block. One end of each connecting arm is hinged to the first connecting ear via a first connecting shaft, and the other end is hinged to the boom via a second connecting shaft.

[0011] As an improved technical solution, the hanger body is provided with a first through hole for the movement of the barrier frame, and the barrier frame passes through the first through hole;

[0012] The barrier frame is also provided with a guide block, and the hanger body is provided with a guide groove corresponding to the guide block, and the guide block is slidably disposed in the guide groove.

[0013] As an improved technical solution, the top of the hanger body is provided with a second connecting lug, and the boom is hinged to the second connecting lug via a third connecting shaft;

[0014] The end of the boom away from the second connecting lug is provided with a lifting ring, which is connected to the lifting cable.

[0015] As an improved technical solution, the hanger body includes a first frame, a second frame, and a third frame connected in sequence. The first frame and the second frame are arranged perpendicularly to each other, and the second frame and the third frame are arranged perpendicularly to each other. The first frame, the second frame, and the third frame together form a U-shaped structure.

[0016] Both the boom and the barrier frame are mounted on the first frame.

[0017] As an improved technical solution, the length of the third frame is smaller than that of the first frame.

[0018] After adopting the above technical solution, the beneficial effects of this utility model are:

[0019] By setting up a hanger body, a boom is hinged to the top of the hanger body, and a lifting cable is connected to the boom. The end of the lifting cable away from the boom is wound around the winch of a winch machine. The winch machine is slidably mounted on a support frame. A stop frame is movably installed on the top of the hanger body near the boom. The stop frame is hinged to the boom via a connecting frame. A flexible stop component is movably installed on the end of the stop frame away from the connecting frame. The flexible stop component and the hanger body form a space to limit and fix the cylinder head. The flexible stop component does not affect the lifting and insertion of the cylinder head, and at the same time, it can automatically pop out to limit the cylinder head. To prevent the cylinder head from detaching from the lifting frame, a barrier frame is installed, which is hinged to the boom via a connecting frame. When the lifting slings lift the boom upwards, the boom rotates, and the barrier frame moves synchronously through the connecting frame, causing the barrier frame to move closer to the cylinder head. This allows the elastic barrier component to abut against one side of the cylinder head, forming a limiting and fixing space for the cylinder head in conjunction with the lifting frame. This prevents the cylinder head from detaching from the lifting frame, thus solving the problem of current lifting devices that rely solely on springs and limit blocks to stop and limit the cylinder head, which poses a risk of cylinder head detachment during use.

[0020] In summary, this utility model provides a cylinder head lifting device that solves the problem that current lifting devices rely solely on springs and limit blocks to stop and limit the cylinder head, which poses a risk of cylinder head detachment during use. Attached Figure Description

[0026] The present invention will be further described below with reference to specific embodiments. However, the uses and purposes of these exemplary embodiments are only for illustrating the present invention and do not constitute any limitation on the actual protection scope of the present invention, nor are they intended to limit the protection scope of the present invention to these embodiments.

[0027] like Figures 1-3 As shown, a cylinder head lifting device includes a lifting frame 1. A lifting arm 2 is hinged to the top of the lifting frame 1. A lifting cable 3 is connected to the lifting arm 2. The end of the lifting cable 3 away from the lifting arm 2 is wound around the winch of a winch 4. The winch 4 is slidably mounted on a support frame 5. A stop frame 6 is movably mounted on the top of the lifting frame 1 near the lifting arm 2. The stop frame 6 is hinged to the lifting arm 2 via a connecting frame 7. An elastic stop component 8 is movably mounted on the end of the stop frame 6 away from the connecting frame 7. The elastic stop component 8 and the lifting frame 1 form a space for limiting and fixing the cylinder head. The elastic stop component 8 does not affect the lifting and insertion of the cylinder head, and at the same time, it can automatically pop out to stop the cylinder head. The cylinder head is limited to prevent it from falling off the lifting frame 1. This is achieved by setting a stop frame 6, which is hinged to the boom 2 via a connecting frame 7. When the lifting cable 3 lifts the boom 2 upward, the boom 2 rotates and moves synchronously with the stop frame 6 via the connecting frame 7. This causes the stop frame 6 to move closer to the cylinder head, and the elastic stop assembly 8 to abut against one side of the cylinder head. Together with the lifting frame 1, this forms a limiting and fixing space for the cylinder head, thus preventing it from falling off the lifting frame 1. This solves the problem that current lifting devices rely solely on springs 802 and limit blocks 803 to stop and limit the cylinder head, which poses a risk of cylinder head falling off during use.

[0028] Furthermore, in practical applications, to ensure the stability of the cylinder head during hoisting and to avoid problems such as tilting and collision, two cylinder head hoisting devices in this application are used simultaneously.

[0029] Combination Figures 2-3As shown, the elastic blocking assembly 8 includes a blocking sleeve 801, which is slidably fitted onto the blocking frame 6. The inner cavity of the blocking sleeve 801 is provided with a spring 802, which is compressed between the blocking frame 6 and the blocking sleeve 801. By setting the spring 802, the blocking sleeve 801 can compress the spring 802 and move upward along the blocking frame 6 when subjected to external force, so that the hanger body 1 can be inserted into the lifting hole of the cylinder head. After the cylinder head is inserted, the blocking sleeve 801 returns to its initial state under the elastic force of the spring 802, thereby achieving the limiting and blocking of the cylinder head.

[0030] Combination Figures 2-3 As shown, a limiting block 803 is provided at one end of the barrier frame 6 connected to the barrier sleeve 801. The limiting block 803 is slidably installed inside the barrier sleeve 801. The limiting block 803 is set to prevent the barrier sleeve 801 from detaching from the barrier frame 6.

[0031] The barrier frame 6 is provided with a first connecting ear 9 at the end away from the limiting block 803. The first connecting ear 9 is hinged to the connecting frame 7. The first connecting ear 9 facilitates the connection between the barrier frame 6 and the connecting frame 7.

[0032] Combination Figure 2 As shown, the connecting frame 7 includes two connecting arms 701 arranged opposite to each other. The two connecting arms 701 are connected by a connecting block 702. One end of the two connecting arms 701 is hinged to the first connecting ear 9 through the first connecting shaft 10, and the other end is hinged to the boom 2 through the second connecting shaft 11. The structural strength of the connecting frame 7 is enhanced by setting the two connecting arms 701 and the connecting block 702, while facilitating the connection with the first connecting ear 9 and the boom 2.

[0033] Combination Figures 1-3 As shown, the hanger body 1 is provided with a first through hole 12 for the movement of the barrier frame 6. The barrier frame 6 passes through the first through hole 12. In this embodiment, the first through hole 12 is provided with an elliptical structure to facilitate the movement and limiting of the barrier frame 6.

[0034] The barrier frame 6 is also provided with a guide block 13, and the hanger body 1 is provided with a guide groove 14 corresponding to the guide block 13. The guide block 13 is slidably disposed in the guide groove 14. In this embodiment, the guide block 13 is designed with a rectangular structure and the guide groove 14 is designed with an elliptical structure. By setting the guide block 13 and the guide groove 14, it is convenient to move, guide and limit the barrier frame 6.

[0035] Combination Figures 1-3 As shown, the top of the hanger body 1 is provided with a second connecting lug 15, and the boom 2 is hinged to the second connecting lug 15 through a third connecting shaft 16. The second connecting lug 15 facilitates the connection between the boom 2 and the hanger body 1.

[0036] The end of the boom 2 away from the second connecting lug 15 is provided with a lifting ring 17, which is connected to the lifting cable 3.

[0037] Combination Figures 1-3 As shown, the hanger body 1 includes a first frame 101, a second frame 102, and a third frame 103 connected in sequence. The first frame 101 and the second frame 102 are arranged vertically, and the second frame 102 and the third frame 103 are arranged vertically. The first frame 101, the second frame 102, and the third frame 103 together form a U-shaped structure. The U-shaped structure design facilitates the insertion of the cylinder head. In conjunction with the structure of the blocking frame 6 and the blocking sleeve 801, the cylinder head is blocked and limited, preventing the cylinder head from falling off the hanger body 1.

[0038] The boom 2 and the barrier frame 6 are both mounted on the first frame 101, and the third frame 103 passes through the lifting hole of the cylinder head.

[0039] Combination Figures 1-3 As shown, the length of the third frame 103 is smaller than that of the first frame 101, which facilitates the cylinder head compression arrestor sleeve 801 and spring 802 to be inserted into the lifting frame 1 during hoisting.

[0040] For ease of understanding, the working process of this embodiment is described below:

[0041] like Figures 1-3 As shown, firstly, the blocking sleeve 801 of the elastic blocking assembly 8 is pressed against the cylinder head and pressure is applied. The blocking sleeve 801 compresses the spring 802 and moves upward along the blocking frame 6, so that the third frame 103 of the hanger body 1 passes through the lifting hole of the cylinder head. When the cylinder head is inserted into the hanger body 1, the blocking sleeve 801 returns to its initial state under the elastic force of the spring 802.

[0042] Afterwards, the winch 4 is started. The winch of the winch 4 winds up the lifting cable 3. The lifting cable 3 drives the boom 2 to rotate to a vertical position. During the rotation of the boom 2, the boom 2 drives the barrier frame 6 to move in the first through hole 12 through the connecting frame 7. During the movement, the barrier frame 6 is guided by the guide block 13 and the guide groove 14, so that the barrier sleeve 801 abuts against one side of the cylinder head. Together with the hanger body 1, it forms a limiting and fixing space for the cylinder head, thereby preventing the cylinder head from falling off the hanger body 1 during hoisting, making it safer and more convenient to use.

[0043] In summary, this utility model provides a cylinder head lifting device that solves the problem that current lifting devices rely solely on springs and limit blocks to stop and limit the cylinder head, which poses a risk of cylinder head detachment during use.
