[0019] The application will be described in detail below with reference to the accompanying drawings and embodiments, but it should be understood that the scope of protection of the application is not limited by the specific embodiments, and the application is described with reference to the accompanying drawings and embodiments Figures 1-12 .

[0020] As shown in Figure 1 , a multi-scene application multifunctional modular diesel engine lifting device includes: crossbeam connecting bolt assembly 1, positioning screw 2, crossbeam unit 3, spring 4, lever connecting bolt assembly 5, lever 6, pull rope 7, cushion block assembly 8, limit pin assembly 9, lifting beam unit 10, Y-shaped lifting chain 11, damping controller 12, safety rope 13; the crossbeam connecting bolt assembly 1 connects the crossbeam unit 3 with external equipment, threaded holes are drilled on the main body of the channel steel of the crossbeam unit 3, the positioning screw 2 is connected to the crossbeam unit 3 and is screwed from bottom to top until the end face is on the driving equipment. The positioning screw 2 mainly relies on the friction between the screw end face and the driving equipment surface to limit the horizontal displacement of the crossbeam unit 3, thereby preventing the lifting device of the hoisted diesel engine from moving forward and backward when running horizontally in the air. The damping controller 12 is installed in the crossbeam unit 3, and the cushion block assembly 8 is fixedly installed below the damping controller 12; the spring 4 connects the crossbeam unit 3 and the lever 6, the lever connecting bolt assembly 5 is connected with the lever 6, the pull rope 7 is connected with the lever 6, and the limit pin assembly 9 is installed on the crossbeam unit 3 and placed on the lever 6; the lifting beam unit 10 is hung on the rotating hook of the crossbeam unit 3, the Y-shaped lifting chain 11 is hung on the lifting chain hanging plate of the lifting beam unit 10, and the safety rope 13 fixes the crossbeam unit 3 and the lifting beam unit 10 together.

[0021] In this embodiment, for the diesel engine with front and rear lifting points, one Y-shaped lifting chain is used for each lifting point of the diesel engine. Each Y-shaped lifting chain has three hooks, one of which hangs the diesel engine, and the other two hooks hang in the holes of the lifting chain hanging plate 10.5 of the lifting beam unit 10 according to the center of gravity of the diesel engine. Finally, it is ensured that the center of gravity of the diesel engine and the rotating hook 3.6 remain on a vertical line. The damping controller 12 in this embodiment is composed of a large torque spring. The safety rope 13 binds the crossbeam unit 3 and the lifting beam unit 10 together to achieve the purpose of double protection, preventing the hoisted diesel engine from falling off after the rotating hook 3.6 of the crossbeam unit 3 falls off.

[0022] As shown in Figure 2 , the crossbeam unit 3 is connected with external equipment, the first hinged hole bolt 1.1 in the crossbeam connecting bolt assembly 1 passes through the hole on the fixed connection plate 3.1 on the crossbeam unit 3, and then the first flat washer 1.2 and the first nut 1.3 are installed in turn, and after fastening, the first split pin 1.4 is inserted through the processing hole of the first hinged hole bolt 1.1, and the tail is forked. After installation is completed, it can play the role of connecting the diesel engine lifting device with electromechanical equipment.

[0023] As shown in Figure 3 , the crossbeam unit 3 is connected with external equipment, the first hinged hole bolt 1.1 in the crossbeam connecting bolt assembly 1 passes through the hole on the fixed connection plate 3.1 on the crossbeam unit 3, and then the first flat washer 1.2 and the first nut 1.3 are installed in turn, and after fastening, the first split pin 1.4 is inserted through the processing hole of the first hinged hole bolt 1.1, and the tail is forked. After installation is completed, it can play the role of connecting the diesel engine lifting device with electromechanical equipment.Figure 4 As shown in the figure, the fixed connection plate 3.1, the main body channel steel 3.2, the vibration reduction controller sleeve 3.3, the lever fixed plate 3.4, the limiting pin sleeve 3.5 and the rotating hook 3.6 of the cross beam unit 3 are fixed together, a total of six sub-pieces. The vibration reduction controller sleeve 3.3 is mainly installed with the vibration reduction controller 12, the limiting pin sleeve 3.5 is mainly placed with the limiting pin assembly 9, and the rotating hook 3.6 can rotate 360 degrees.

[0024] As shown in the figure, Figure 5 and Figure 6 The cushion assembly 8 is composed of three internal hexagonal screws 8.1, three third open nuts 8.2, three third open pins 8.3 and three cushion blocks 8.4. The cushion assembly 8 is suspended below the vibration reduction controller 12, mainly to reduce the distance between the cross beam of the hoisting beam unit 10 and the vibration reduction controller 12, and further reduce the front and rear swing amplitude of the diesel engine during horizontal transportation in the air.

[0025] As shown in the figure, Figure 7 The limiting pin assembly 9 is composed of a limiting pin 9.1 and a stud 9.2, and a threaded hole is processed in the vertical direction along the limiting pin axis. The end of the stud 9.2 is threaded, and the threaded part of the stud 9.2 is coated with thread glue, and is screwed into the threaded hole of the limiting pin 9.1. The other end of the stud 9.2 is processed as a boss.

[0026] As shown in the figure, Figure 8 The lever connecting bolt assembly 5 is mainly composed of a second hinge hole bolt 5.1, a second flat washer 5.2, a second nut 5.3 and a second open pin 5.4. The second hinge hole bolt 5.1 passes through the round hole of the lever fixed plate 3.4 on the cross beam unit 3, and then the lever 6, and then the second flat washer 5.2 and the second nut 5.3 are installed in turn, and after being tightened, the second open pin 5.4 is inserted into the processing hole of the second hinge hole bolt 5.1, and the tail is forked. After the connection is completed, the lever 6 can rotate around the second hinge hole bolt 5.1, and the limiting pin assembly 9 in contact with one end of the lever 6 rises or falls with the rotation of the lever 6. The stud 9.2 of the limiting pin assembly 9 has a boss at one end, which prevents the lever 6 from rotating too much and losing contact with the limiting pin assembly 9.

[0027] As shown in the figure, Figure 9The shown lever 6 is connected to the lever fixing plate 3.4 on the beam unit 3 through the lever connecting bolt assembly 5, and the lever 6 can rotate around the light pole. One end of the lever 6 is connected to the pull rope 7, and the other end of the lever 6 is connected to the stud 9.2 of the limiting pin assembly 9. When the diesel engine reaches the predetermined position, the limiting pin of the limiting pin assembly 9 at the other end of the lever 6 is lifted up from the limiting hole of the beam unit 10, and the diesel engine hung below the beam unit 10, the Y-shaped lifting chain 11 and the diesel engine can rotate easily, and the diesel engine ground receiving and delivering device can be easily connected. The spring 4 connects the lever 6 to the beam unit 3, and when the diesel engine is hung on the diesel engine lifting device with multiple scene applications and multiple functions, the spring pulls the one end of the lever 6 up, and the limiting pin 9.1 of the limiting pin assembly 9 at the other end falls into the limiting hole 10.2 of the beam unit 10, which plays a mechanical limiting role and prevents the diesel engine from swinging greatly during horizontal transportation in the air.

[0028] As shown in Figure 10 , Figure 11 and Figure 12 , the beam unit 10 includes a beam 10.1, a limiting hole 10.2, a beam fixing plate 10.3, an auxiliary reinforcing plate 10.4, a lifting chain hanging plate 10.5 and a U-shaped ring 10.6. The beam unit 10 plays a role of connecting the upper and lower parts, and the upper part is hung on the rotating hook 3.6 of the beam unit 3, and the lower part is hung on the hole of the lifting chain hanging plate 10.5. Different lengths of diesel engines can choose different positions of the lifting chain hanging plate 10.5. For diesel engines with large length, the lifting chain hanging plates 10.5 at both ends are preferably used, and for diesel engines with small length, the lifting chain hanging plate 10.5 in the middle can be used. The installation positions of the two lifting points of the diesel engine before and after are different, and the center of gravity also differs greatly. According to the different center of gravity, the two hooks of the Y-shaped lifting chain 11 on each side are hung in different holes of the same lifting chain hanging plate 10.5, so as to finally ensure that the center of gravity of the lifting device and the diesel engine is on a vertical line, and the safety and reliability coefficient is improved.

[0029] The diesel engine lifting device uses the principle of lever, and through the application of small force, the limiting pin is lifted or fallen from the limiting pin hole, so that the diesel engine lifting device can rotate or be fixed, and other buffer measures are assisted to ensure that the diesel engine is safely and smoothly transported, and quickly connected and transferred after reaching the destination. The diesel engine lifting device belongs to a multifunctional lifting device, reduces the replacement frequency of the lifting device, and improves the production efficiency. Meanwhile, the multiple hole hanging positions can meet the safe lifting requirements of diesel engines with different structures and different sizes, and have high compatibility.

[0030] The multi-scene application multifunctional modular diesel engine hoisting device has compact structure, reasonable layout and high reliability, is suitable for hoisting diesel engines with a length of 0.5-4 m, effectively meets the accurate transfer requirements of diesel engines with front and rear hoisting points, realizes the functional requirements of safe transfer and accurate docking, and effectively improves the transfer efficiency in the diesel engine production process. Meanwhile, for the damaged hoisting device, the damaged module can be quickly replaced or repaired, thereby reducing the production manufacturing cost.
