Description

Technical Field

[0001] This utility model relates to an installation structure for a gas generator set, belonging to the field of generator set installation technology. Background Technology

[0002] A gas generator set is a small power generation device that converts combustible gases such as natural gas into electrical energy. Combustible gases such as natural gas are transported to the generator through pipelines. The engine and generator are coaxially connected. When the gas burns inside the engine, the generated power drives the generator to rotate, thereby producing electrical energy.

[0003] Currently, the mounting base of most gas generator sets adopts an integral welded structure. The engine assembly and generator assembly are fixed to the base by bolts. During the assembly of the unit, the engine assembly and generator assembly need to be hoisted onto the base one after another for docking and assembly. During the assembly process, it is difficult to align the center line of the engine power output shaft with the center line of the generator in one go, which is prone to deviation. Since the engine assembly and generator are large in size and weight, once their positions are fixed, they are not easy to adjust, which makes docking the engine assembly and generator assembly difficult and slows down the alignment and assembly speed.

[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] This utility model addresses the shortcomings of the prior art by providing an installation structure for a gas generator set, which facilitates the alignment and adjustment of the generator input shaft and the engine output shaft, thereby improving the assembly speed of the generator input shaft and the engine output shaft.

[0006] To solve the above technical problems, the present invention adopts the following technical solution:

[0007] The installation structure of the gas generator set includes a welded base, which consists of an upper frame and a lower frame. The upper frame and the lower frame are flush at one end along their length, and the length of the upper frame is less than the length of the lower frame.

[0008] The engine assembly is fixedly installed on the top of the upper structure, and the linear slide rail, slider, transverse slide seat, slewing bearing, slewing seat and generator assembly are installed sequentially from bottom to top on the lower structure at the end away from the upper structure.

[0009] A horizontally arranged telescopic cylinder is installed between the upper and lower frames. The head of the telescopic cylinder is connected to the transverse sliding seat through a fixed lug A.

[0010] Furthermore, the linear slide rails are arranged side by side along the length of the lower frame.

[0011] Furthermore, the slider is fixed to the bottom of the transverse sliding seat, and the slider is slidably connected to the linear slide rail.

[0012] Furthermore, the tail of the telescopic cylinder is hinged to the fixed lug B via a pin, and the fixed lug B is fixedly installed between the upper frame and the lower frame.

[0013] Furthermore, the generator assembly is fixed to the rotary base.

[0014] Furthermore, the bottom of the slewing seat is fixedly connected to the top of the slewing bearing, and the bottom of the slewing bearing is fixedly connected to the top of the transverse seat.

[0015] Furthermore, the rotary seat has multiple upper positioning holes arranged in a circular pattern on its outer periphery, and the transverse seat has multiple lower positioning holes arranged in a circular pattern on its outer periphery.

[0016] Furthermore, the position of the rotary seat is fixed by a locking pin, which passes vertically through the corresponding upper and lower positioning holes.

[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0018] In this invention, the generator assembly is fixed to the top of the slewing base. The generator assembly can rotate along the slewing support, so that the center line of the generator assembly input shaft is collinear with the center line of the engine assembly output shaft. Then, the position of the generator assembly is locked by the locking pin, and then the telescopic cylinder retracts, so that the generator assembly moves towards the engine assembly and completes precise docking, which significantly improves the docking and assembly speed of the generator input shaft and the engine output shaft.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0024] like Figure 1 and Figure 2 As shown in the figure, the present invention provides an installation structure for a gas generator set, including a welding base 3. The welding base 3 is composed of an upper frame 301 and a lower frame 302. The upper frame 301 and the lower frame 302 are flush at one end along the length direction, and the length of the upper frame 301 is less than the length of the lower frame 302.

[0025] The engine assembly 1 is fixedly installed on the top of the upper frame 301, and the lower frame 302, from bottom to top, is equipped with a linear slide rail 4, a slider 5, a transverse slide seat 6, a slewing bearing 7, a slewing seat 8, and a generator assembly 2.

[0026] The linear slide rails 4 are arranged side by side along the length of the lower frame 302.

[0027] The slider 5 is fixed to the bottom of the transverse sliding seat 6, and the slider 5 is slidably connected to the linear slide rail 4.

[0028] A fixed lug A601 is installed on the end of the transverse sliding seat 6 near the upper frame 301. A horizontally arranged telescopic cylinder 9 is installed between the upper frame 301 and the lower frame 302. The head of the telescopic cylinder 9 is hinged to the fixed lug A601 by a pin, and the tail of the telescopic cylinder 9 is hinged to the fixed lug B10 by a pin. The fixed lug B10 is fixedly installed between the upper frame 301 and the lower frame 302.

[0029] The telescopic cylinder 9 provides power for the translation of the generator assembly 2, facilitating docking between the generator assembly 2 and the opposing ends of the engine assembly 1. After docking, the telescopic cylinder 9 can be removed from the welded base 3.

[0030] The generator assembly 2 is fixedly connected to the rotary base 8.

[0031] The bottom of the slewing seat 8 is fixedly connected to the top of the slewing bearing 7, and the bottom of the slewing bearing 7 is fixedly connected to the top of the transverse seat 6. The generator assembly 2 can rotate along the slewing bearing 7, which facilitates the centering adjustment of the generator assembly 2 and the engine assembly 1.

[0032] The rotary seat 8 has multiple upper positioning holes 801 arranged in a circle on its outer periphery, and the transverse seat 6 has multiple lower positioning holes 602 arranged in a circle on its outer periphery.

[0033] The position of the rotary seat 8 is fixed by a locking pin 11, which is vertically inserted into the corresponding upper positioning hole 801 and lower positioning hole 602.

[0034] The specific working principle of this utility model is as follows:

[0035] First, the engine assembly 1 is fixedly installed on the top of the upper frame 301, and the generator assembly 2 is fixedly connected to the top of the slewing base 8. The generator assembly 2 can rotate along the slewing bearing 7 so that the center line of the input shaft of the generator assembly 2 is collinear with the center line of the output shaft of the engine assembly 1. Then, the position of the generator assembly 2 is locked by the locking pin 11. Then, the telescopic cylinder 9 retracts, so that the generator assembly 2 moves towards the engine assembly 1 and completes precise docking.
