Description

Technical Field

[0001] The utility model relates to a chassis of a generating set, in particular to a hidden pull-out chassis. Background Art

[0002] A generating set usually needs to be installed on a chassis, and at the same time, the chassis needs to carry other necessary components such as a fuel tank and a battery.

[0003] In order to save space, during the space layout stage of the generating set, the arrangement of the upper unit and the lower fuel tank is often adopted, the unit is elevated by the unit chassis, and the fuel tank is fixed below the chassis; later, in order to reduce the overall height of the unit, the chassis and the fuel tank are set as an integrated structure. This way, the chassis is inconvenient to disassemble, and the fuel tank needs to be cleaned regularly. Therefore, although this structural form optimizes the space, it is not conducive to the later maintenance and disassembly of the fuel tank. The fuel tanks placed in the above two forms have the problem of incomplete oil suction and oil discharge. Content of the Utility Model

[0004] The utility model provides a hidden pull-out chassis to solve the problems in the prior art.

[0005] To solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A hidden pull-out chassis includes two longitudinals arranged at intervals, and the longitudinals all extend in the front-rear direction; several crossbeams are fixedly connected to the upper parts of the longitudinals, and generator fixing beams are arranged on the crossbeams according to the positions of the units.

[0007] A first chassis and a second chassis distributed front and rear are fixedly connected between the longitudinals, and are separated by a partition board between the first chassis and the second chassis;

[0008] The space between the crossbeam and the first chassis is a fuel tank installation space. The first chassis is inclined in the left-right direction. One end of the first chassis away from the partition board forms a fuel tank installation inlet between the longitudinal and the crossbeam. The fuel tank is pushed into the fuel tank installation space through the fuel tank installation inlet and placed on the first chassis;

[0009] The space between the crossbeam and the second chassis is a battery installation space. One end of the second chassis away from the partition board forms a battery installation inlet between the longitudinal and the crossbeam. The battery is pushed into the battery installation space through the battery installation inlet and placed on the second chassis.

[0010] Preferably, the inclination angle of the first chassis is 3-5°.

[0011] Preferably, a detachable baffle is fixedly provided at the fuel tank inlet, and the baffle and the partition board respectively form a limit fit with the front and rear ends of the fuel tank.

[0012] Preferably, there are two unit positions on the upper part of the longitudinal beam, including a first unit position above the first chassis and a second unit position above the second chassis;

[0013] At the first unit position, a first cross beam is arranged, and a first engine fixing beam is fixedly arranged on the first cross beam, and the first engine fixing beam extends in the left - right direction;

[0014] At the second unit position, at least two second cross beams are arranged, and at least two second engine fixing beams are fixedly arranged on the second cross beams, and the second engine fixing beams extend in the front - back direction.

[0015] Preferably, a radiator support is also arranged on the longitudinal beam beside the second unit position.

[0016] Preferably, the main body of the longitudinal beam is a channel steel. The flat side of the channel steel is fixedly connected to the first chassis and the second chassis, and short sides are fixed at both ends of the open side of the channel steel, and a number of reinforcing plates are fixedly arranged in the open cavity surrounded by each side.

[0017] Preferably, the sharp - angled parts of the reinforcing plates are chamfered.

[0018] Preferably, weight - reducing holes are opened on the first chassis and the second chassis.

[0019] Advantages of the present utility model:

[0020] 1. In the present utility model, the chassis is supported by welding the longitudinal beam and the cross beam. While reducing weight, it meets the open space for the pull - out fuel tank and does not affect the installation of the units above.

[0021] 2. Due to the load - bearing of the first chassis, when installing the fuel tank, it is directly pushed in between the first chassis and the cross beam. The fuel tank is hidden and used in the unit chassis. During later maintenance, the fuel tank can be pulled out reversely when maintaining the fuel tank. This placement method is more flexible. There is no need to limit the installation of a baffle at the open end of the fuel tank to prevent the fuel tank from slipping out of the chassis.

[0022] 3. The first chassis meets the requirements of the fuel tank for inclined fuel supply and discharge, ensuring the concentration of the oil volume and avoiding the situation of incomplete oil suction and discharge.

[0023] 4. The second chassis is used to place the battery, and the partition plays a role in separating oil and electricity, reducing the occurrence of accidents. Description of the Drawings

[0033] The accompanying drawings are only for illustrative purposes and should not be construed as limiting the present patent; for better illustration of this embodiment, some components in the accompanying drawings may be omitted, enlarged or reduced, which do not represent the dimensions of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the accompanying drawings may be omitted. Specific embodiments

[0034] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0035] As Figures 1 to 9 shown, this embodiment provides a hidden pull-out chassis, including two longitudinally arranged longitudinal beams 3, and the longitudinal beams 3 all extend in the front-rear direction; a plurality of cross beams 4 are fixedly connected to the upper part of the longitudinal beams 3, and generator fixing beams are arranged on the cross beams 4 according to the positions of the units.

[0036] A first chassis 1 and a second chassis 2 are fixedly connected between the longitudinal beams 1 and are separated by a partition 6.

[0037] The space between the cross beam 4 and the first chassis 1 is an oil tank installation space. The first chassis 1 is inclined in the left-right direction, and the inclination angle is 3-5°. The first chassis is used to place the oil tank. One end of the first chassis 1 away from the partition forms an oil tank installation inlet between the longitudinal beam 3 and the cross beam 4. The oil tank is pushed into the oil tank installation space through the oil tank installation inlet and placed on the first chassis 1.

[0038] Specifically during processing, the first chassis 1 is composed of a straight plate and an inclined plate that are fixedly joined. The inclined angle of the inclined plate is 3 - 5°, the straight plate is located at the lower end, and the straight plate is horizontally arranged. The inclined plate part effectively ensures the flow of the oil fluid towards the lower place, and the gravity is applied to the straight plate part, which ensures that the fuel tank will not slide down and squeeze against the side wall of the unit chassis.

[0039] In this way, the fuel tank is placed obliquely on the first chassis 1, and the oil flows towards the lower end. The suction pipe and the drain port of the fuel tank are both arranged at the lower end of the fuel tank, thus solving the problem of incomplete oil suction and drainage. At the same time, due to the load-bearing of the first chassis 1, when installing the fuel tank, it is directly pushed in from the fuel tank installation inlet, and the fuel tank is hidden and used in the unit chassis. During later maintenance, the fuel tank can be directly pulled out. At the same time, it is not limited to fixedly arranging a detachable baffle at the fuel tank installation inlet. The blocking plate and the partition 6 respectively form a limit fit with the front and rear ends of the fuel tank to prevent the fuel tank from slipping out of the chassis.

[0040] The space between the cross beam 4 and the second chassis 2 is the battery installation space. An opening for installing the battery is formed between the end of the second chassis 2 away from the partition and the longitudinal beam 3 and the cross beam 4. The battery is pushed into the battery installation space from the battery installation inlet and placed on the second chassis. In this way, the partition 6 plays a role in separating oil and electricity, reducing the occurrence of accidents.

[0041] Weight-reducing holes are also opened on the first chassis 1 and the second chassis 2.

[0042] In this embodiment, there are two unit positions on the upper part of the longitudinal beam 3, including a first unit position above the first chassis 1 and a second unit position above the second chassis 2.

[0043] At the first unit position, a first cross beam 41 is arranged in a row. A first engine fixing beam 71 is fixedly arranged on the first cross beam 41, and the first engine fixing beam 71 extends in the left-right direction;

[0044] At the second unit position, two second cross beams 42 are arranged in a row. Two second engine fixing beams 72 are fixedly arranged on the second cross beams 42, and the second engine fixing beams 72 extend in the front-rear direction.

[0045] At the same time, a radiator support 8 is also arranged on the longitudinal beam 3 beside the second unit position.

[0046] In this embodiment, the main body of the longitudinal beam 3 is a channel steel. The planar side of the channel steel is fixedly connected to the first chassis 1 and the second chassis 2. Short sides are fixed at both ends of the open side of the channel steel. A number of reinforcing plates 9 are fixedly arranged in the open cavity surrounded by each side. In order to smoothly place the reinforcing plates 9 into the open cavity, the sharp corners of the reinforcing plates are chamfered. The part of the reinforcing plate in contact with the longitudinal beam is welded and connected to enhance the support performance of the longitudinal beam for the unit and fuel tank parts.
