Description

Technical Field

[0001] The utility model relates to the technical field of gas generator sets, in particular to a chassis of a gas generator set. Background Technique

[0002] Gas generator sets are new types of generator sets developed to meet the world's environmental protection requirements and the new market environment. Natural gas generator sets are mainly divided into two types. One is a combined cycle gas turbine, and the other is a gas internal combustion engine. Gas turbines have relatively large power and are mainly used in large and medium-sized power stations. Gas internal combustion engines have relatively small power and are mainly used in small distributed power stations. It is a new type of green and environmental protection power to replace fuel and coal-fired units.

[0003] Through retrieval, it is found that the Chinese patent publication number: CN217634643U discloses a chassis of a gas generator set, including a base and an adjustment component. A first buffer spring connected to a buffer sleeve is sleeved on the surface of the installation rod. The upper end of the base is movably installed with a bottom plate. The bottom plate is mutually extruded by a first elastic buffer plate and a second elastic buffer plate, having a certain buffer effect. The first elastic buffer plate moves along the surface of the installation rod through a sliding sleeve. The sliding sleeve and the buffer sleeve move relatively to compress the first buffer spring. During the deformation of the second elastic buffer plate, the movable block is driven to move along the sliding rod inside the installation rail to compress the second buffer spring. Under the action of the first buffer spring and the second buffer spring, a good buffer effect is achieved between the bottom plate and the base. At the same time, under the action of the first magnet and the second magnet, the buffer effect is enhanced, which is convenient for protecting the gas generator set and reducing shaking.

[0004] However, the existing chassis is made of steel plates combined by welding and is mainly used for generator sets with small weights. As the weight of the generator set increases, the requirements for the strength and deformation of the chassis are getting higher and higher. If it is still made of steel plates welded together, it will cause problems such as a large amount of welding work and easy deformation of the chassis. Therefore, a high-strength chassis is proposed to solve this problem. Content of the Utility Model

[0016] Furthermore, a limiting plate is fixed to the outer surface of the four small-diameter steel pipes on one side close to the large-diameter steel pipe, and the outer diameter of the limiting plate is greater than the inner diameter of the large-diameter steel pipe.

Detailed implementation mode

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1 to 2 , a chassis of a gas generator set in this embodiment includes two main beams 1, a plurality of longitudinal beams 2, two engine bases 3, two generator bases 4, and a unit accessory base 5. The longitudinal beams 2 are fixed between the opposite sides of the two main beams 1. Two rectangular steel profiles are used as the main beams 1, and other functional modules are concentrated on the main beams 1, making the overall structure of the chassis compact and the welding process simple. The two main beams 1 are connected by the longitudinal beams 2, increasing the lateral structural strength of the chassis. The two engine bases 3 are arranged on the upper surfaces of the two main beams 1. The engine bases 3 are in the middle of the chassis, arranged in the middle of the upper surfaces of the two main beams 1, increasing the overall structural strength of the chassis. The two generator bases 4 are fixed at the left ends of the upper surfaces of the two main beams 1, and the unit accessory base 5 is fixed at the right ends between the opposite sides of the two main beams 1. The other end of the chassis is the unit accessory base 5, which can be a radiator base or a supercharger intercooler module base. Lifting mechanisms 7 for lifting the unit are provided at the left and right ends of the opposite sides of the two main beams 1, and an adjusting mechanism 8 for adjusting the size of the engine base 4 is provided in the middle between the opposite sides of the two main beams 1.

[0031] In this embodiment, the main beam 1 is a rectangular steel profile. A reinforcing cross beam 6 is fixed between the opposite sides of the two longitudinal beams 2 and located between the engine base 3 and the generator base 4. There is a reinforcing cross beam 6 between the engine base 3 and the generator base 4, improving the connection strength between the engine and the generator. The cross-sectional shape of the engine base 3 is trapezoidal, and the inclined surfaces of the two engine bases 3 are on the opposite sides of the two engine bases 3. The entire chassis adopts a welded structure, and all structures are welded and fixed on the main beam 1, having the characteristics of a small chassis width, simple structure, small welding workload, high structural strength, and small deformation.

[0032] It should be noted that the bottom of the chassis (i.e., the middle and the right end of the bottom between the opposite sides of the two main beams 1) adopts a closed structure to form an oil collecting pan to collect the oil stains on site. The closed structure forms a closed cavity by welding a steel plate to the main beam 1 at the bottom of the chassis, which can collect the oil stains generated during the operation of the unit.

[0033] Please refer to Figures 3 - 4, in order to avoid interference between the hoisting steel wire rope and both sides of the unit, the hoisting mechanism 7 in this embodiment includes four large-diameter steel pipes 71, four small-diameter steel pipes 72 and several sliding blocks 73. The four large-diameter steel pipes 71 are respectively fixed at the left and right ends of the opposite sides of the two main beams 1. The small-diameter steel pipes 72 are arranged in the inner cavities of the large-diameter steel pipes 71. Chutes 74 are opened at both the left and right ends of the large-diameter steel pipes 71. Two of the sliding blocks 73 are fixed on the left and right sides of the small-diameter steel pipes 72.

[0034] In this embodiment, the inner diameters of the four large-diameter steel pipes 71 are adapted to the outer diameters of the four small-diameter steel pipes 72. The four large-diameter steel pipes 71 and the four small-diameter steel pipes 72 are evenly distributed at the left and right ends of the vertical central axes of the two main beams 1. The size of the inner cavity of the chute 74 is adapted to the size of the sliding block 73. The sliding block 73 makes a horizontal linear motion in the inner cavity of the chute 74. When the small-diameter steel pipe 72 extends out of the large-diameter steel pipe 71, the movement of the small-diameter steel pipe 72 drives the sliding blocks 73 on its left and right sides to move in the inner cavity of the chute 74, and the movement of the small-diameter steel pipe 72 can be limited.

[0035] Among them, limit plates are fixed on the outer surfaces of the four small-diameter steel pipes 72 on the side close to the large-diameter steel pipes 71, and the outer diameters of the limit plates are larger than the inner diameters of the large-diameter steel pipes 71.

[0036] It should be noted that with the double-layer steel pipe structure, the small-diameter steel pipe 72 is sleeved in the large-diameter steel pipe 71. The small-diameter steel pipe 72 can be retracted into the large-diameter steel pipe 71 when not in use. During hoisting, the limit plate can be pulled to make the small-diameter steel pipe 72 extend out of the large-diameter steel pipe 71, and the two together form a hoisting structure.

[0037] Please refer to Figure 5 , in order to meet the installation requirements of different models of generators, the adjusting mechanism 8 in this embodiment includes four connecting plates 81 and eight connecting blocks 82. The four connecting plates 81 are evenly fixed in the middle between the opposite sides of the two main beams 1. Four of the connecting blocks 82 are evenly fixed on the lower surface of the engine base 3. When the engine base 3 moves, the connecting blocks 82 fixed on its lower surface slide between the two connecting plates 81, and the movement of the engine base 3 can be limited.

[0038] In this embodiment, the size between the left and right connecting plates 81 is adapted to the size of the connecting blocks 82. The two engine bases 3 move relatively or away from each other on the outer surfaces of the two main beams 1.

[0039] It should be noted that limiting grooves are opened on the opposite sides of the left and right connecting plates 81, and limiting blocks are fixed on both the left and right sides of the connecting plates 81. The limiting blocks make a horizontal linear motion in the inner cavities of the limiting grooves.

[0040] It can be understood that the size of the adjustable engine base 3 can be adjusted to adapt to the sizes of different models of engines, so as to meet the installation requirements of different models of engines and improve the adaptability.

[0041] The working principle of the above embodiment is as follows:

[0042] (1) Two rectangular steel profiles are used as the main beams 1, and other functional modules are concentrated on the main beam 1, making the overall structure of the chassis compact and the welding process simple. The two main beams 1 are connected by longitudinal beams 2, which increases the lateral structural strength of the chassis. The engine base 3 is located in the middle of the chassis, at the middle of the upper surfaces of the two main beams 1, which increases the overall structural strength of the chassis. There is a strengthening cross beam 6 between the engine base 3 and the generator base 4, which improves the connection strength between the engine and the generator. The other end of the chassis is the unit accessory base 5, which can be a radiator base or a supercharger intercooler module base. The bottom of the chassis (i.e., the middle and the right end of the bottom between the opposite sides of the two main beams 1) adopts a closed structure to form an oil collecting pan to collect the on-site oil stains. The closed structure uses steel plates to weld with the main beam 1 at the bottom of the chassis to form a closed cavity, which can collect the oil stains generated during the operation of the unit.

[0043] (2) A double-layer steel pipe structure is adopted. The small-diameter steel pipe 72 is sleeved inside the large-diameter steel pipe 71. The small-diameter steel pipe 72 can be retracted into the large-diameter steel pipe 71 when not in use. When lifting, the limit plate is pulled to make the small-diameter steel pipe 72 extend out of the large-diameter steel pipe 71, and the two together form a lifting structure. When the small-diameter steel pipe 72 extends out of the large-diameter steel pipe 71, the movement of the small-diameter steel pipe 72 drives the sliding blocks 73 on its left and right sides to move in the inner cavity of the sliding groove 74, which can limit the movement of the small-diameter steel pipe 72. One end of the chassis is the engine base 3. By making the two engine bases 3 move relatively or away from each other, when the engine base 3 moves, the connecting block 82 fixed to its lower surface slides between the two connecting plates 81, making the limit blocks fixed on the left and right sides of the connecting block 82 move in the inner cavity of the limit groove, which can limit the movement of the engine base 3. The size of the engine base 3 can be adjusted to adapt to the sizes of different models of engines, so as to meet the installation requirements of different models of engines and improve the adaptability.
