Abstract

This utility model provides a combined piston head lifting device, belonging to the field of processing technology. It includes a lifting ring with two iron chains on its surface. A first lifting arm and a second lifting arm are respectively mounted at the other end of each chain. A mandrel is positioned between the first and second lifting arms. A base support is fixedly installed at the other end of each of the first and second lifting arms. A piston head body is positioned between the first and second lifting arms. The lifting ring and iron chains are welded together, and the iron chains are welded to both the first and second lifting arms. The first and second lifting arms are cross-connected, and the mandrel is located at the intersection point. This utility model utilizes the gravity generated by the piston head body during lifting. Its own weight causes the hinge formed by the first and second lifting arms and the mandrel to clamp tightly, further ensuring that the base support is firmly engaged in the annular groove on the surface of the piston head body under the clamping force, thus improving the stability and safety of the piston head body during lifting.

Description

Technical Field

[0001] This utility model belongs to the field of processing technology, specifically relating to a combined piston head lifting device. Background Technology

[0002] Large, low-speed engine combined pistons typically have piston heads made of heat-resistant alloy steel. Large piston heads are usually machined using vertical machine tools. The traditional method of hoisting is to use lifting slings. After machining, the outer surface is smooth. However, traditional lifting slings cannot guarantee safety during the hoisting process. Multiple lifting slings are usually wrapped around the piston multiple times to ensure safety, resulting in low processing efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a combined piston head lifting device, which aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A combined piston head lifting device includes a lifting ring, on the surface of which two iron chains are provided. The other end of each iron chain is provided with a first lifting arm and a second lifting arm, respectively. A spindle is provided between the first lifting arm and the second lifting arm. A base is fixedly installed at the other end of the first lifting arm and the second lifting arm, respectively. A piston head body is provided between the first lifting arm and the second lifting arm.

[0006] In a preferred embodiment of this utility model, the lifting ring and the iron chain are welded together, and the iron chain is welded to the first boom and the second boom respectively.

[0007] In a preferred embodiment of this utility model, the first boom and the second boom are cross-connected, and the spindle is located at the intersection point.

[0008] As a preferred embodiment of this utility model, the surface of the piston head body is provided with several annular grooves, and the end of the base is engaged with the inside of the annular grooves.

[0009] As a preferred embodiment of this utility model, the dimensions of the bottom support end are adapted to the dimensions of the annular groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the weight generated by the piston head body during lifting causes the hinge formed by the first boom, the second boom and the spindle to clamp together, and the bottom support is firmly engaged in the annular groove on the surface of the piston head body under the action of clamping force, thereby improving the stability and safety of the piston head body during lifting.

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. Among them:

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example

[0019] Reference Figure 1-2 This is an embodiment of the present utility model, which provides a combined piston head lifting device, including a lifting ring 1. Two iron chains 2 are provided on the surface of the lifting ring 1. A first lifting arm 3 and a second lifting arm 4 are respectively provided at the other end of the iron chains 2. A spindle 5 is provided between the first lifting arm 3 and the second lifting arm 4. A base support 6 is fixedly installed at the other end of the first lifting arm 3 and the second lifting arm 4. A piston head body 7 is provided between the first lifting arm 3 and the second lifting arm 4.

[0020] The piston head body 7, when lifted, is subjected to gravity, which causes it to fall and clamp the hinge formed by the first boom 3, the second boom 4, and the spindle 5. This further ensures that the base support 6 is firmly engaged in the annular groove on the surface of the piston head body 7 under the action of clamping force, thereby improving the stability and safety of the piston head body 7 during lifting.

[0021] Specifically, the lifting ring 1 and the iron chain 2 are welded together, and the iron chain 2 is welded to the first boom 3 and the second boom 4 respectively.

[0022] Furthermore, the first boom 3 and the second boom 4 are cross-connected, with the spindle 5 located at the intersection.

[0023] Preferably, the surface of the piston head body 7 is provided with several annular grooves, and the end of the base 6 is engaged with the inside of the annular grooves.

[0024] The annular groove is used to improve the clamping stability of the base support 6 on the piston head body 7, thereby improving the lifting stability of the piston head body 7.

[0025] Furthermore, the dimensions of the bottom support 6 end are matched with the dimensions of the annular groove.

[0026] In this way, by matching the size of the end of the base support 6 with the size of the annular groove, the snapping stability between the end of the base support 6 and the annular groove is improved, thereby improving the clamping stability of the base support 6 on the piston head body 7.

[0027] In use, the first boom 3, the second boom 4 and the spindle 5 form a hinge structure. When lifting the piston head body 7, the weight of the piston head body 7 causes the first boom 3, the second boom 4 and the spindle 5 to form a hinge clamping force, which clamps the base 6 in the annular groove on the surface of the piston head body 7, thereby clamping the piston head body 7.

[0028] In summary, the gravity generated by the piston head body 7 during lifting causes it to fall and clamp together with the hinge formed by the first boom 3, the second boom 4, and the spindle 5. This further ensures that the base support 6 is firmly engaged in the annular groove on the surface of the piston head body 7 under the action of the clamping force, thereby improving the stability and safety of the piston head body 7 during lifting.
