Description

Technical Field

[0001] This utility model relates to the field of generator technology, specifically a diesel generator lifting device. Background Technology

[0002] A diesel generator set is a power supply device that uses a diesel engine as the prime mover to drive a synchronous generator to generate electricity. It is a power generation device that starts quickly, is easy to operate and maintain, requires less investment, and has strong adaptability to the environment. It mainly consists of an engine, a generator, and a control system.

[0003] A search revealed a lifting device for a diesel generator set disclosed in Chinese Patent Publication No. CN 209081242 U. The diesel generator set includes a base, a generator body, and four lifting holes on the base. The lifting device includes a horizontally positioned main beam and two symmetrically arranged secondary beams fixed at both ends of the main beam. The main beam has a sliding sleeve that can slide along its length and several locking holes evenly distributed along its length. A lifting ring is located at the upper end of the sliding sleeve. A locking pin is detachably mounted on the sliding sleeve, and a locking nut is attached to the locking pin. Each secondary beam has a boom at both ends, its upper end vertically rotatable and hinged to the secondary beam. Each boom has a shackle detachably mounted on its lower end, and a sling for engaging with the corresponding lifting hole. This design improves lifting efficiency and safety.

[0004] The diesel generator lifting device used in the aforementioned patent still has certain shortcomings. Although the existing diesel generator lifting device supports the generator through the base and lifts the base and generator together, the generator will tilt during the lifting process due to the different weights on the left and right sides of the generator. This increases the difficulty of lifting and installing the generator, and the tilted generator is also more troublesome for subsequent installation and adjustment. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a diesel generator lifting device. This device solves the problem that while existing diesel generator lifting devices support the generator using a base and lift both the base and the generator together, the generator tilts during lifting due to the different weight distribution on the left and right sides. This increases the difficulty of lifting and installing the generator, and the tilted generator also makes subsequent installation and adjustment more troublesome.

[0006] This utility model provides the following technical solution: a diesel generator lifting device, including a diesel generator body, a generator connecting plate at the bottom of the diesel generator body, two lifting auxiliary plates symmetrically and vertically arranged on both sides of the top of the generator connecting plate, a top lifting frame above the diesel generator body, the top lifting frame and the lifting auxiliary plates being connected by a center of gravity adjusting lifting connection assembly, and a lifting steel wire connected to the middle of the top lifting frame;

[0007] The center of gravity adjustment lifting connection assembly includes symmetrically arranged connection slots at the top of both sides of the lifting auxiliary plate. A fixing block is inserted into the connection slot. A connection hole is opened on the rod of the fixing block. A fixing bolt is threaded into the side of the lifting auxiliary plate. The end of the fixing bolt passes through the connection hole and is inserted into the lifting auxiliary plate. A lifting connection steel wire is connected to the top of the fixing block. Several counterweights for increasing weight are movably sleeved on the lifting connection steel wire.

[0008] The top lifting frame has two symmetrical top fixing holes at its front and rear ends. The top end of the lifting connecting wire is provided with a top insertion rod, and the end of the top insertion rod is inserted into the top fixing hole. Several first locking blocks are evenly arranged on the side of the top insertion rod. An inner wall groove is provided on the inner side wall of the top fixing hole. A fixing push plate is slidably arranged in the inner wall groove. Several second locking blocks are evenly arranged on the side of the fixing push plate.

[0009] Preferred technical solution 1: The inner wall of the inner wall groove is provided with a drive screw hole, and an abutment screw is rotatably disposed in the drive screw hole.

[0010] Preferred technical solution 2: The end of the contact screw is rotatably connected to the center of the side of the inner wall groove, and the upper and lower side walls of the inner wall groove are provided with limiting grooves. A limiting slider is slidably arranged in the limiting groove, and the limiting slider is connected to the side of the fixed push plate.

[0011] Preferred technical solution three: Both the second locking block and the first locking block are triangular in shape that engages in mutual contact.

[0012] This solution enables the top plug-in rod to be more securely inserted into the top lifting frame by the engagement of the second locking block and the first locking block when the fixed push plate is in contact with and fixed to the top plug-in rod.

[0013] Preferred technical solution four: The counterweight is provided in several parts, and each of the several counterweights can be penetrated by a fixing insert.

[0014] This solution allows users to add appropriate counterweights to the lifting connection steel wire according to the weight distribution on the left and right sides of the diesel generator body, so as to achieve a near-horizontal state for the diesel generator body as a whole.

[0015] Preferred technical solution five: The end of the abutting screw is provided with a handle for easy rotation.

[0016] This solution makes it easier for users to rotate the contact screw.

[0017] Compared with the prior art, the present invention provides a diesel generator lifting device, which has the following advantages:

[0018] (1) This utility model provides a lifting auxiliary plate on the side of the diesel generator body. The lifting auxiliary plate is connected to the top lifting frame through a center of gravity adjustment lifting connection assembly. The lifting connection steel wire in the center of gravity adjustment lifting connection assembly can be equipped with counterweights, thereby adjusting the uneven weight distribution on the left and right sides of the diesel generator body. This ensures that the left and right sides of the diesel generator body are similar in mass, so that the diesel generator body can be easily kept in a horizontal state when it is lifted on the generator connection plate without tilting too much. This greatly simplifies the lifting and installation difficulty of the diesel generator body and facilitates subsequent adjustment and installation, thus greatly improving the lifting and installation efficiency of the diesel generator body.

Detailed Implementation

[0026] Please see Figure 1-4 A diesel generator lifting device includes a diesel generator body 1, a generator connecting plate 2 at the bottom of the diesel generator body 1, two lifting auxiliary plates 3 symmetrically and vertically arranged on both sides of the top of the generator connecting plate 2, a top lifting frame 4 above the diesel generator body 1, the top lifting frame 4 and the lifting auxiliary plates 3 are connected by a center of gravity adjustment lifting connection assembly 5, and a lifting wire 6 is connected to the middle of the top lifting frame 4.

[0027] The center of gravity adjustment lifting connection assembly 5 includes connecting slots 501 symmetrically opened at the top of both sides of the lifting auxiliary plate 3. A fixing block 502 is inserted into the connecting slot 501. A connecting hole 503 is opened on the rod of the fixing block 502. A fixing bolt 504 is threaded into the side of the lifting auxiliary plate 3. The end of the fixing bolt 504 passes through the connecting hole 503 and is inserted into the lifting auxiliary plate 3. A lifting connecting steel wire 505 is connected to the top of the fixing block 502. Several counterweights 506 for increasing weight are movably sleeved on the lifting connecting steel wire 505.

[0028] Two top fixing holes 507 are symmetrically opened at the front and rear ends of the top lifting frame 4. A top insertion rod 508 is provided at the top of the lifting connecting steel wire 505. The end of the top insertion rod 508 is inserted into the top fixing hole 507. Several first locking blocks 509 are evenly arranged on the side of the top insertion rod 508. An inner wall groove 510 is opened on the inner side wall of the top fixing hole 507. A fixed push plate 511 is slidably arranged in the inner wall groove 510. Several second locking blocks 512 are evenly arranged on the side of the fixed push plate 511.

[0029] The inner wall of the inner wall groove 510 is provided with a drive screw hole 513. A contact screw 514 is rotatably arranged in the drive screw hole 513. The end of the contact screw 514 is rotatably connected to the side center of the inner wall groove 510. Limiting grooves 515 are provided on the upper and lower side walls of the inner wall groove 510. Limiting sliders 516 are slidably arranged in the limiting grooves 515. The limiting sliders 516 are connected to the side of the fixed push plate 511.

[0030] Example 2: The difference between this example and Example 1 is that the second locking block 512 and the first locking block 509 are both triangular in shape that collide and cooperate with each other.

[0031] When the fixed push plate 511 abuts against and fixes the top plug rod 508, the second locking block 512 abuts against the first locking block 509, ensuring that the top plug rod 508 is more firmly inserted into the top lifting frame 4.

[0032] Example 3: The difference between this example and Example 1 is that there are several counterweights 506, and all of the counterweights 506 can be penetrated by the fixing insert 502.

[0033] This allows users to add appropriate counterweights 506 to the lifting connecting steel wire 505 according to the weight distribution on the left and right sides of the diesel generator body 1, so as to achieve a near-horizontal state for the diesel generator body 1.

[0034] Example 4: The difference between this example and Example 1 is that the end of the contact screw 514 is provided with a handle for easy rotation.

[0035] This makes it easier for users to rotate the contact screw 514.

[0036] In this embodiment, although the existing diesel generator lifting device supports the generator through the base and lifts the base and generator together, the generator tilts during the lifting process due to the different weights on the left and right sides. This increases the difficulty of lifting and installing the generator, and the tilted generator is also more troublesome for subsequent installation and adjustment.

[0037] In summary, during specific implementation, when the user needs to lift and install the diesel generator body 1, in order to ensure that the overall center of gravity of the diesel generator body 1 is located in the middle, fixing blocks 502 are inserted on both sides of the lifting auxiliary plate 3. The fixing blocks 502 are fixedly connected to the top lifting frame 4 by the inserted fixing bolts 504. Before fixing the fixing blocks 502 to the top lifting frame 4, the weight difference between the left and right sides of the diesel generator body 1 needs to be considered.

[0038] A counterweight 506 of appropriate weight is fitted onto the lifting connecting steel wire 505 set at the top of the fixed plug 502, so that the weight of the drive part and the generator part on the left and right sides of the diesel generator body 1 is similar, and the overall center of gravity of the diesel generator body 1 is concentrated at its center position. Thus, when the diesel generator body 1 is lifted by the four lifting connecting steel wires 505 set on the top lifting frame 4, the diesel generator body 1 can be kept in a horizontal state and will not tilt too much.

[0039] Next, by inserting the top plug rod 508 connected to the top of the lifting connecting steel wire 505 into the top fixing hole 507, and by rotating the abutting screw 514 provided on the side of the top plug rod 508, the abutting screw 514 drives the second locking block 512 on the fixed push plate 511 to engage and abut against the first locking block 509 provided on the side of the top plug rod 508, thereby firmly locking the top plug rod 508.

[0040] This makes the connection between the lifting connecting steel wire 505 and the top lifting frame 4 more secure. The crane then lifts the diesel generator body 1, which is connected to the top lifting frame 4 via the center of gravity adjustment lifting connecting assembly 5, by lifting the lifting steel wire 6 on the top lifting frame 4. This greatly simplifies the lifting and installation of the diesel generator body 1 and facilitates subsequent adjustments and installations, thus significantly improving the lifting and installation efficiency of the diesel generator body 1.
