Description

Technical Field

[0001] The invention relates to the technical field of engine parts, in particular to an engine hoisting structure. Background Art

[0002] During the assembly or disassembly of the engine, it is often necessary to lift the engine cylinder head or the entire engine. The original lifting method is to set connection holes for lifting ears on the cylinder head or the engine body, which damages the side of the cylinder head or the engine body; or to cast lifting ears on the cylinder head or the engine body, which requires multiple pairs of lifting ears, occupies a large space, and wastes material costs.

[0003] In addition, in existing truck models, the engine is generally installed under the cab according to the structural characteristics of the cab. Existing lifting lugs are often limited to a single function of lifting. With the development of the integration of gas engines and the increasing requirements for compactness of the engine compartment space, the single-function lifting lugs no longer meet the requirements of the existing technology for the engine.

[0004] In addition, the engine also needs to install a bracket specially designed for the air filter. For example, Chinese patent CN106917705A discloses a device for supporting the air filter, including a plurality of connectors connected to the engine cylinder head to install the air filter on the engine compartment, a connecting plate connected to all the connectors to form an integral device is provided above the plurality of connectors, a bracket connected to the connecting plate and supporting the air filter is detachably provided above one end of the connecting plate, and a limit frame connected to the connecting plate and capable of limiting the axial displacement of the air filter is detachably provided above the other end, and an annular locking device with an adjustable diameter to change the tightness of the air filter is provided on the bracket and the limit frame.

[0005] However, the bracket structure in the above scheme has a single function, and the engine hoisting, wiring harness oil pipe installation, and air filter installation are performed separately, the installation process is complicated, and the cost is high. Summary of the invention

[0006] In view of the above-mentioned existing defects, the purpose of the present invention is to provide an engine hoisting structure that can meet the needs of hoisting the cylinder head alone or the entire engine, and also has the function of fixing the wiring harness and the pipe, thereby improving the compactness of the engine compartment space.

[0007] The technical solution of the present invention is as follows:

[0008] An engine hanging structure, comprising a plurality of connecting members connected to an engine cylinder head for mounting an air filter on an engine compartment, wherein the number of the connecting members is more than two, a truss is connected and arranged above the connecting members, the truss connects all the connecting members to form a whole, the truss is arranged to cover above the engine cylinder head, and a bracket for supporting the air filter is detachably connected above the truss;

[0009] The two ends of the truss are respectively provided with a front lifting ear and a rear lifting ear, the upper ends of the front lifting ear and the rear lifting ear are respectively connected to the two ends of the truss, and the lower ends of the front lifting ear and the rear lifting ear are respectively connected to the front end face and the rear end face of the engine; the middle part of the front lifting ear and the rear lifting ear is respectively provided with a limiting channel for the wiring harness or pipeline of the engine to pass through.

[0010] Specifically, the front lifting ear includes a vertically arranged front vertical plate, a front horizontal plate arranged on the outer side of the upper end of the front vertical plate and extending along the length direction of the truss, and a front lifting hole arranged on the front horizontal plate; a front mounting hole for installing a fan is arranged on the side surface of the lower end of the front vertical plate; an L-shaped rib is connected between the outer end of the front horizontal plate and the lower end of the front vertical plate, and a front limiting channel for the wiring harness or pipeline of the engine to pass through is formed between the inner side surface of the L-shaped rib, the bottom of the front horizontal plate, and the outer side surface of the front vertical plate.

[0011] Specifically, the rear lifting ear includes a vertically arranged rear vertical plate, a rear horizontal plate arranged on the outer side of the upper end of the rear vertical plate and extending along the length direction of the truss, and a rear lifting hole arranged on the rear horizontal plate; the lower end of the rear vertical plate is provided with a bending portion recessed inward, and the side surface of the lower end of the bending portion is provided with a rear mounting hole for installing the flywheel housing, and the inner side of the rear vertical plate, the bending portion, the bottom of the truss, and the side surface of the rear end of the engine form a rear limiting channel for the engine wiring harness or pipeline to pass through.

[0012] Specifically, the L-shaped ribs are connected to the front transverse plate and the front vertical plate respectively by welding.

[0013] Specifically, the rear lifting ear is an integrally formed part.

[0014] Specifically, the upper ends of the inner side surfaces of the front vertical plate and the rear vertical plate are respectively connected to the two ends of the truss by bolts through L-shaped connecting pieces.

[0015] Specifically, weight-reducing holes are provided on the front vertical plate and the rear vertical plate.

[0016] Specifically, the width of the front limiting channel is 20-30 mm, and the width of the rear limiting channel is 10-20 mm. The widths of the front limiting channel and the rear limiting channel not only ensure the space for the pipeline and the wiring harness to pass through, but also reduce the space for the pipeline to be arranged outside the engine.

[0017] Beneficial effects of the present invention:

[0018] 1. The present invention connects the air filter, the cylinder head, the lifting lug and the engine body through a truss, so it is very convenient to disassemble the air filter, lift and remove the cylinder head and lift and remove the engine body. Only one pair of lifting lugs is needed, the structure is simple, and the labor intensity is reduced;

[0019] 2. The air filter of the present invention can be installed on a hoisting mechanism, so the position on the vehicle originally used to install the air filter can be used for other purposes, and the air intake pipeline connecting the air filter to the gas engine is greatly shortened, saving space;

[0020] 3. The lifting lug of the present invention has both the lifting function and the function of fixing the wiring harness and the pipeline, thus achieving multiple uses and saving space around the engine;

[0021] 4. The entire hoisting structure truss and weight-reducing holes of the present invention have multiple weight-reducing designs, which ensure a firm installation and a weight-reducing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention connects the air filter 2, the cylinder head 1, the lifting lugs, and the main body of the engine 8 through the truss 4. When lifting the cylinder head 1 or lifting the engine 8 as a whole, it is only necessary to remove or install the mounting hole and the engine 8 for lifting. The cylinder head 1 is connected to the truss 4 through the connecting piece 3. The truss 4 structure can improve the stability of lifting and reduce the weight of the cylinder head 1 at the same time. Based on the above scheme, the present embodiment is very convenient in disassembling and assembling the air filter 2, lifting and removing the cylinder head 1, and lifting and removing the main body of the engine 8. Only a pair of lifting lugs is needed, the structure is simple, and the labor intensity is reduced. The air filter 2 can be installed on the lifting mechanism, so the position originally used for installing the air filter 2 on the whole vehicle can be used for other purposes, and the intake pipe connecting the air filter 2 to the engine 8 is greatly shortened, saving space. The lifting lug has both the lifting function and the function of fixing the wiring harness and the pipeline, realizing multiple uses of one object, further saving the space around the engine, and achieving the purpose of the present invention.

[0031] Embodiment 2:

[0032] The present embodiment further provides an engine hoisting structure, comprising a plurality of connecting members 3 connected to the engine cylinder head 1 so as to install the air filter 2 on the engine compartment 8; a truss 4 connected to all the connecting members 3 to form a whole is provided above the plurality of connecting members 3; the truss 4 completely covers the top of the engine cylinder head 1; a bracket 5 connected to the truss 4 and supporting the air filter 2 is detachably provided above the truss 4; a front lifting ear 6 and a rear lifting ear 7 are respectively provided at both ends of the truss 4; the upper ends of the front lifting ear 6 and the rear lifting ear 7 are respectively connected to the two ends of the truss 4, and the lower ends of the front lifting ear 6 and the rear lifting ear 7 are respectively connected to the front end face and the rear end face of the engine 8; the middle parts of the front lifting ear 6 and the rear lifting ear 7 are respectively provided with limiting channels for the engine wiring harness or pipeline.

According to the requirements of the engine, the connecting pipe of the air filter points to the front lifting ear, so the connecting pipe can pass through the space surrounded by the L-shaped rib 12 to connect with the air filter, saving the space required for the connecting parts fixed on the periphery of the engine; the L-shaped rib can be set to an oblique strip shape to achieve the function of fixing the wiring harness or pipeline, and at the same time can reduce the weight.

[0034] like Figure 2 as well as Figure 4 As shown, in this embodiment, the rear lifting lug 7 includes a rear vertical plate 13 arranged vertically, and a rear horizontal plate 14 arranged outside the upper end of the rear vertical plate 13 and extending along the length direction of the truss 4, and a rear lifting hole 15 is arranged on the rear horizontal plate 14; the lower end of the rear vertical plate 13 is provided with a bent portion 16 recessed inwardly, and the lower end side of the bent portion 16 is provided with a rear mounting hole for mounting the flywheel housing, and the inner side of the rear vertical plate 13, the bent portion 16, the bottom of the truss 4, and the rear end side of the engine 8 form a rear limiting channel 19 for the engine 8 wiring harness or pipeline to pass through. Similarly, the bent portion 16 forms an inner hole-type space to achieve the function of fixing the wiring harness or pipeline.

[0035] In this embodiment, the L-shaped ribs 12 are connected to the front transverse plate 10 and the front vertical plate 9 respectively by welding, thereby reducing the cost of processing parts.

[0036] In this embodiment, the rear lifting ear 7 is an integrally formed part, which reduces the number of parts and is easy to install.

[0037] In this embodiment, the upper ends of the inner sides of the front vertical plate 9 and the rear vertical plate 13 are connected to the two ends of the truss 4 through L-shaped connectors 17.

[0040] Embodiment 3:

[0041] The difference between this embodiment and the above-mentioned Embodiment 2 is that the width of the front limiting channel 18 is 30 mm, and the width of the rear limiting channel 19 is 20 mm. The setting of this size ensures the space for the pipes and wiring harnesses of the front limiting channel 18 and the rear limiting channel 19 to pass through.

[0042] Although the present invention has been described in detail above with specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention.
