[0001] This utility model relates to the field of frame assembly technology, and in particular to an engine frame cylinder liner suspension device. Background Technology

[0002] The assembly of the engine frame involves the installation of cylinder liners at the ends and the sealing technology of the cylinders. Because the cylinder liners for the engine frame are heavy, conventional assembly methods typically involve lifting the product by binding it to the inner bore, and then assembling it according to assembly requirements. However, binding the cylinder liners can cause tensile damage to the inner bore, affecting the accuracy of subsequent engine frame assembly. Utility Model Content

[0003] The purpose of this utility model is to provide an engine frame cylinder liner suspension device to solve the problems encountered in the above-mentioned background art.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] An engine frame cylinder liner suspension device includes a base support, a top cover, and a lifting rod. The base support is an isosceles triangular structure with abutment portions on both sides. The lifting rod passes through the middle of the top cover, and its through end is movably connected to the middle of the base support. The base support and the top cover clamp the engine frame cylinder liner in the middle. The base support lifts the bottom surface of the engine frame cylinder liner through the abutment portions, and the top cover presses against the top surface of the engine frame cylinder liner through its lower plane.

[0006] The lifting rod is threaded and has a lifting hole at its top. When suspending the cylinder liner of the machine frame, the bottom of the lifting rod is threaded to the base support, and the middle of the lifting rod is locked to the top cover by a fastening sleeve and a nut.

[0007] The above solution also includes a lifting ring, which has a U-shaped structure and is rotatably connected to the lifting hole via a pin.

[0008] In one embodiment, the base includes two side plates, each side plate being an isosceles triangle, and the two side plates are fixedly connected by a connecting plate; the abutment is provided on both sides of each side plate, and each side plate has a guide bevel on its top side.

[0009] As a preferred embodiment, a transition section with an arc-shaped structure is provided between the guide bevel and the abutment. Each side plate has a through hole, and a locking block is installed in the through hole and threadedly connected to the bottom of the lifting rod; the edge of the abutment has an arc-shaped structure.

[0010] In one embodiment, the top cover includes two pressure plates, which are rectangular in structure, and the two pressure plates are fixedly connected on both sides by a baffle; each pressure plate has a pressure groove on both sides of its bottom.

[0011] The top of the top cover has an upper pad block connecting two pressure plates in the middle, and the bottom of the top cover has a lower pad block connecting two pressure plates in the middle. The upper and lower pad blocks are respectively provided with threaded holes for rotating connection with the suspension rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: by using this hanging device, the product does not need to be lifted by binding from the inner hole during the hanging process of the engine frame cylinder liner. Instead, the frame cylinder liner is directly clamped in the middle by the bottom support and the top cover. The inner hole of the frame cylinder liner will not be damaged during the entire hanging process. Therefore, this hanging device can be used for the hanging work of engine frame cylinder liners and maintain good frame assembly accuracy. Attached Figure Description

[0024] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Example 1, such as Figure 1 As shown, an engine frame cylinder liner suspension device includes a base support 1, a top cover 2, and a lifting rod 3. The base support 1 has an isosceles triangular structure, and abutment portions 13 are provided on both sides of the base support 1 to support and lift the bottom of the engine frame cylinder liner. The lifting rod 3 passes through the middle of the top cover 2, and its through end is movably connected to the middle of the base support 1. This connection is adjustable using threads.

[0026] During the engine frame cylinder liner hoisting process, the base support 1 and the top cover 2 clamp the engine frame cylinder liner in the middle. Specifically, the base support 1 lifts the bottom surface of the engine frame cylinder liner through the abutment part 13, and the top cover 2 presses the top surface of the engine frame cylinder liner with its lower plane, stabilizing the entire hoisting process to facilitate the assembly of the engine crankshaft.

[0027] Please see Figure 7 The lifting rod 3 is threaded and has a lifting hole 32 fixed at its top, through which it can be suspended individually. When suspending the cylinder liner of the frame, the bottom of the lifting rod 3 is threaded to the base support 1, and the middle part of the lifting rod 3 is locked to the top cover 2 by fastening sleeve 31 and nut 33.

[0028] Example 2, based on the solution of Example 1, provides an engine frame cylinder liner suspension device, including a base support 1, a top cover 2, and a suspension rod 3, as well as a suspension ring 4. The suspension ring 4 has a U-shaped structure and is rotatably connected to the suspension hole 32 via a pin 41. By connecting the suspension ring 4, the suspension hole slot is enlarged, allowing for direct suspension with a hook on the vehicle.

[0029] Example 3, please refer to Figures 2 to 4Based on the scheme of Embodiment 1, the base support 1 includes two side plates 11, each side plate 11 having an overall isosceles triangular structure, and the two side plates 11 are fixedly connected by a connecting plate 12. The connecting plate 12 has a block-shaped structure. By setting the two side plates 11 and connecting and fixing them together, the thickness between the two side plates 11 can be widened, thereby better lifting the cylinder liner of the frame.

[0030] The abutment 13 is provided on both sides of each side plate 11. When the bottom support 1 is installed at the bottom of the frame cylinder liner, the abutment 13 abuts against the bottom sides of the frame cylinder liner. Each side plate 11 is provided with a guide bevel 14 on the top side so that the frame cylinder liner can be automatically guided to the middle position of the bottom support 1 during installation.

[0031] A transition section 16 is provided between the guide bevel 14 and the abutment part 13. The transition section 16 has an arc-shaped structure, which facilitates the bottom of the frame cylinder liner to engage with the abutment part 13 through the smooth transition section 16 when the frame cylinder liner is suspended. Each side plate 11 has a through hole 15. A locking block is installed in the through hole 15 and threadedly connected to the bottom of the lifting rod 3. The locking block has a square structure, with its top side threadedly connected to the bottom of the lifting rod 3, and its two sides inserted into the through hole 15 and locked by clamps. In addition, since the frame cylinder liner is a cylindrical structure, the edge of the abutment part 13 is designed to be arc-shaped.

[0032] Example 4, please refer to Figures 5 to 6 Based on the scheme of Embodiment 1, the top cover 2 includes two pressure plates 21, each with a rectangular structure. The two pressure plates 21 are fixedly connected by welding between their two sides via a baffle 23. The baffle 23 connects the two pressure plates 21, widening the distance between them and facilitating a greater range of pressure on the top surface of the frame cylinder liner during assembly. Each pressure plate 21 has pressure grooves 26 on both sides of its bottom. The pressure grooves 26 have a relief slope that moves towards the center. When installed on the top surface of the frame cylinder liner, the top surface of the frame cylinder liner is pressed tightly by the pressure grooves 26.

[0033] As a preferred embodiment, an upper pad 24 connecting two pressure plates 21 is welded to the center of the top of the top cover 2, and a lower pad 25 connecting two pressure plates 21 is welded to the center of the bottom of the top cover 2. The upper pad 24 and lower pad 25 are respectively provided with threaded holes 22 for rotatable connection with the hanger rod 3. By welding and adding two pads, a foundation is provided for the threaded connection of the hanger rod 3, thus facilitating the external thread of the hanger rod 3 to pass through the top cover 2 and then be threadedly connected to the base support 1.

[0034] When installing this hanging device, the frame cylinder liner can be laid flat first, with the middle hole horizontal, making it easy for the base support 1 to be inserted into the bottom of the cylinder liner. Then, the lifting rod 3 and the top cover 2 connected to the lifting rod 3 are placed on top of the frame cylinder liner. By adjusting the depth of the lifting rod 3, the tail of the lifting rod 3 is inserted into the locking block in the middle of the base support 1. Finally, the middle part of the lifting rod 3 is locked with the top cover 2 through the fastening sleeve 31 and the nut 33, thereby clamping the frame cylinder liner in the middle. Then, it can be lifted by directly inserting the cable or by using the lifting ring 4.

[0035] Based on the solutions in Embodiments 1-4, this hanging device can be used to hang the engine frame cylinder liner without binding the product through the inner hole. Instead, the bottom support 1 and the top cover 2 are used to clamp the frame cylinder liner in the middle. The entire hanging process will not damage the inner hole of the frame cylinder liner. Therefore, this hanging device is suitable for the hanging of engine frame cylinder liners.

[0036] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
