Description

Technical Field

[0001] The utility model belongs to the technical field of assembly and disassembly of diesel generators, in particular to an assembly and disassembly tool for a diesel generator. Background Art

[0002] A diesel generator set is a power source that uses a diesel engine as the prime mover to drive a synchronous generator. It is a power generation device that features quick start-up, easy operation and maintenance, low investment, and strong environmental adaptability. A diesel generator set primarily consists of a diesel engine, generator, control and protection system, and other auxiliary components.

[0003] Currently, the loading and unloading of components (generators) from traditional diesel generator sets primarily relies on manual operation or the assistance of on-site cranes. While traditional, manual loading and unloading is inefficient, labor-intensive, and carries significant safety risks, such as increased risk of injury from falling objects. In contrast, using cranes for loading and unloading significantly improves efficiency and reduces the labor burden.

[0004] However, while cranes operate quickly, their operational stability is relatively limited. During the lifting process, the hoisting ropes are prone to shaking and swinging, potentially causing personal injury or accidental damage to equipment. Furthermore, frequent calls for lifting equipment not only significantly increase project costs but can also extend the overall construction period, impacting project progress. Given these challenges, exploring more efficient, economical, and convenient loading and unloading solutions is crucial. Therefore, we designed a diesel generator assembly and unloading tool. Utility Model Content

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a diesel generator assembly and disassembly tooling that solves the technical problems of existing loading and disassembly tooling, such as insufficient stability, prone to personal injury and accidental collision damage to equipment, resulting in excessive costs, thereby reducing the overall construction period.

[0006] To achieve the above-mentioned purpose, according to an embodiment of the first aspect of the present utility model, a diesel generator assembly and disassembly tool is provided, comprising an assembly and disassembly base and guide seats arranged in ports on both sides of the assembly and disassembly base;

[0007] Also includes:

[0008] The loading and unloading base is arranged on the surface of the loading and unloading base, and the two sides are respectively connected to the inner sides of a pair of guide seats;

[0009] A clamping and fixing mechanism includes a double-headed screw rotatably arranged in a loading and unloading base, a sliding seat arranged on opposite threaded teeth at both ends of the double-headed screw, and a U-shaped clamping rod arranged on the surface of each sliding seat, a pair of grooves on the surface of the loading and unloading base, and the top surfaces at both ends of each U-shaped clamping rod respectively pass through the grooves.

[0010] A further improvement is that a pair of push-pull hydraulic cylinders are provided on the same side of the loading and unloading base, and a pair of guide seats are connected to the rod end of each push-pull hydraulic cylinder. The guide rods are located parallel to and above each push-pull hydraulic cylinder in the ports on both sides of the loading and unloading base, and each guide seat is movably mounted on the guide rod. A push-pull hydraulic cylinder is provided on the side of the loading and unloading base, and a push plate is provided at the rod end of the push-pull hydraulic cylinder.

[0011] A further improvement is that an installation cavity is provided in the loading and unloading base, and a double-headed screw is rotatably provided in the installation cavity. The double-headed screw is driven by a DC servo motor externally arranged outside the loading and unloading base, and the main shaft of the DC servo motor is connected to the double-headed screw.

[0012] A further improvement is that the inner sides of the pair of clamping rods on the same side are connected to clamping molds through fixing bolts, and a clamping notch is provided on the inner side of each clamping mold.

[0013] A further improvement is that track grooves with opposite ends are additionally provided on the side surfaces of the two outer clamping rods, a baffle is slidably provided in the track groove, and an elastic protective pad is connected to the inner wall surface of the baffle.

[0014] A further improvement is that the two inner side surfaces of the clamping rod are additionally connected to limit plates.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) The utility model activates a DC servo motor to drive the double-headed screw to rotate. The two sides of the double-headed screw are designed with thread teeth in opposite directions. These thread teeth act on a pair of sliding seats and a pair of U-shaped clamping rods respectively, causing them to move toward each other and gradually approach each other. As this process proceeds, the clamping molds in the pair of U-shaped clamping rods accurately align and clamp the target model generator, and the body of the generator is firmly embedded in the clamping notch of the clamping mold, thereby achieving stable fixation and clamping of the generator; and the matching baffle is smoothly slid and installed along a pair of track grooves to ensure that the elastic pad on the inside of the baffle fits tightly to the side of the generator end, thereby achieving stable limitation and comprehensive protection of the generator side.

[0017] (2) The utility model uses the synergistic effect of the push-pull hydraulic cylinder 1 and the push-pull hydraulic cylinder 2 to push / pull the guide seat together with the loading and unloading base and the generator to move smoothly, thereby realizing convenient loading and unloading of the generator in the diesel generator. This innovative design significantly reduces the risk of shaking and collapse of the generator set components during the unloading process, greatly improves the stability and safety of the loading and unloading operation, and at the same time speeds up the loading and unloading efficiency, effectively reducing project costs and shortening the overall construction period.

[0025] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1 and Figure 2 As shown, a diesel generator assembly and disassembly tool comprises an assembly and disassembly base 1 and guide seats 14 arranged in ports on both sides of the assembly and disassembly base 1;

[0027] The loading and unloading base 3 is provided on the surface of the loading and unloading base 1, and the two sides are respectively connected to the inner sides of a pair of guide seats 14;

[0028] Specifically, as a preferred embodiment, a pair of push-pull hydraulic cylinders 11 are provided on the same side of the loading and unloading base 1, and a pair of guide seats 14 are connected at the rod end of each push-pull hydraulic cylinder 11. Guide rods 13 are located parallel to and above each push-pull hydraulic cylinder 11 in the ports on both sides of the loading and unloading base 1. Each guide seat 14 is movably sleeved on the guide rod 13. A push-pull hydraulic cylinder 2 12 is provided on the side of the loading and unloading base 3. A push plate is provided at the rod end of the push-pull hydraulic cylinder 2 12. The size of the push plate is selected according to the specifications of the generator. Through the coordinated action of the pair of push-pull hydraulic cylinders 11 and the push-pull hydraulic cylinder 2 12, the guide seat 14, the loading and unloading base 3 and the generator are pushed / pulled together to move smoothly, thereby realizing convenient loading and unloading of the generator in the diesel generator.

[0029] like Figure 1 and Figure 3 As shown, when implemented, it includes: a clamping and fixing mechanism 2, which includes a double-ended screw 23 rotatably set in the loading and unloading base 3, a sliding seat 24 set on the opposite thread teeth at both ends of the double-ended screw 23, and a U-shaped clamping rod 22 set on the surface of each sliding seat 24, a pair of grooves 21 on the surface of the loading and unloading base 3, and the top surfaces of both ends of each U-shaped clamping rod 22 respectively pass through the groove 21;

[0030] Specifically, as a preferred embodiment, an installation cavity 31 is provided in the loading and unloading base 3, and a double-headed screw 23 is rotatably provided in the installation cavity 31. The double-headed screw 23 is driven by a DC servo motor 25 externally provided on the outside of the loading and unloading base 3. The main shaft of the DC servo motor 25 is connected to the double-headed screw 23, and the double-headed screw 23 is driven to rotate by activating the DC servo motor 25. The two sides of the double-headed screw 23 are designed with thread teeth in opposite directions. These thread teeth act on a pair of sliding seats 24 and a pair of U-shaped clamping rods 22 respectively, causing them to move toward each other and gradually approach. As this process proceeds, the clamping mold 201 in the pair of U-shaped clamping rods 22 accurately aligns with and clamps the generator of the target model, thereby achieving stable fixation and clamping of the generator;

[0031] Specifically, as a preferred embodiment, the inner sides of the pair of clamping rods 22 on the same side are connected to a clamping mold 201 via fixing bolts. A clamping notch 202 is provided on the inner side of each clamping mold 201. The clamping mold 201 is selected according to the specifications of the generator. When clamping, the clamping notch 202 is used to firmly embed the body of the generator into the clamping notch 202 to achieve stable clamping.

[0032] like Figure 2As shown, in this embodiment, a track groove 203 with opposite ends is provided on the side of the two outer clamping rods 22, a baffle 204 is slidably provided in the track groove 203, and the inner wall surface of the baffle 204 is connected to an elastic pad 205, and the two inner clamping rods 22 are connected to the side of the limiting plate 206, which is used to limit the side of the generator to facilitate auxiliary clamping and fixation.

[0033] like Figures 1 to 3 As shown, it should also be noted that the application documents of this embodiment are mainly aimed at loading and unloading the generator components of the diesel generator set; for the loading and unloading of other components, loading and unloading are carried out by replacing different clamping molds 201; before implementation, the loading and unloading tooling is installed on the mobile vehicle body and pushed to the unloading platform of the production workshop. The loading / unloading platform of the production workshop and the loading / unloading platform of the assembly workshop are pre-set, and the height of the loading / unloading platform is the same as the surface height of the loading and unloading base 3.

[0034] In addition, it should be noted that this application document only aims to improve the shortcomings of the existing loading and unloading tooling, which is insufficient in stability, prone to personal injury and accidental collision damage to equipment, resulting in excessive costs, thereby reducing the overall construction period, and does not involve other aspects. The following is an introduction to the working principle of this diesel generator assembly and unloading tooling:

[0035] When using this new model, on-site staff connect the push plate at the end of the generator to the side of the generator base and ensure that the side of the generator's main shaft is aligned with the side where the limit plate 206 is located. Then, by operating the rod of the push-pull hydraulic cylinder 2 12, the tension generated by it is used to smoothly pull the generator and its base together and place them on the loading and unloading base 3 until the sides of the generator are tightly attached to the limit plates 206 arranged symmetrically on both sides, completing the generator loading operation.

[0036] Next, the DC servo motor 25 is activated to drive the double-ended screw 23 to rotate. The two sides of this double-ended screw 23 are designed with threaded teeth in opposite directions. These threads act on a pair of sliding seats 24 and a pair of U-shaped clamping rods 22, respectively, causing them to move toward each other and gradually approach each other. As this process proceeds, the clamping mold 201 within the pair of U-shaped clamping rods 22 precisely aligns and clamps the target model generator. The generator body is firmly embedded in the clamping notch 202 of the clamping mold 201, thus achieving stable fixation and clamping of the generator.

[0037] Afterwards, a suitable baffle 204 is selected and smoothly slid along a pair of track grooves 203, ensuring that the elastic pad 205 inside the baffle 204 fits snugly against the side of the generator's end, thereby providing secure positioning and comprehensive protection for the generator's side. Upon arrival at the assembly workshop, the push-pull hydraulic cylinders 11, built into the ports on either side of the loading and unloading platform 1, are first activated. Through the synergistic action of these push-pull hydraulic cylinders 11, the guide seat 14, along with the loading and unloading base 3 and the generator, is smoothly moved to one side until the side of the loading and unloading base 3 and the unloading platform in the assembly workshop are level. Next, the push-pull hydraulic cylinder 2 12 is operated, leveraging its rod force to steadily push the generator and its base off the surface of the loading and unloading base 3, ultimately placing them safely on the unloading platform in the assembly workshop. This innovative design significantly reduces the risk of shaking and collapsing of generator set components during unloading, significantly improving the stability and safety of loading and unloading operations while accelerating loading and unloading efficiency, effectively reducing project costs, and shortening the overall construction period.

[0038] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
