Description

Technical Field

[0001] The utility model relates to a rigid base in the technical field of diesel generator assembly. Background Art

[0002] High-power diesel generators are generally used for emergency power generation. They are large in volume, heavy in weight, and irregular in shape. Therefore, a base needs to be provided for them. The base is assembled and fixed with the installation frame on site to facilitate use or transportation. In the prior art, the base of the diesel generator is a rectangular frame, and the whole diesel generator is installed on the upper surface of the rectangular frame and is bolted to the diesel generator through several fixing seats, resulting in less contact area between the diesel generator and the base. Thus, the overall height of the diesel generator together with the base is relatively high, and the rectangular frame needs to be thicker and higher to better support the diesel generator, resulting in a large manufacturing cost of the base. Moreover, when the diesel generator and the base are transported together, together with the supporting bracket (pallet), the overall height exceeds the height of the diesel generator by a large margin. Therefore, a higher container is required, resulting in an increase in transportation costs. Content of the Utility Model

[0003] The purpose of the utility model is to provide a rigid base for a high-power diesel generator, effectively reducing the overall height, weight and manufacturing cost.

[0004] To achieve the above purpose, the utility model provides a rigid base for a high-power diesel generator, which includes a pair of side frames. A support structure is connected between the front sections of the side frames. A fixing structure is arranged at the top of the front section of the side frames. A positioning structure is arranged on the rear half section of the side frames. A threading structure is arranged on the rear half section of the side frames.

[0005] Compared with the prior art, the beneficial effect of the utility model lies in that the whole is composed of two side frames. The diesel generator is fixedly connected with the side frames through the support structure, the fixing structure, the positioning structure and the threading structure. And the lower part of the diesel generator sinks between the side frames, and the oil pan extends out between the side frames. Thus, after the diesel generator together with the base is assembled with the installation frame, its actual height is only a little larger than the height of the diesel generator itself, which can effectively reduce the height of the transportation space. At the same time, the base is composed of two side frames, and the overall mass and height are effectively reduced, and thus the manufacturing cost is reduced.

[0006] As a further improvement of the utility model, the support structure includes four support blocks. The two ends of the support blocks are fixedly connected with the side frames. The latter three support blocks are fixedly connected side by side. A connecting plate is connected between the bottom of the frontmost support block and the adjacent support block. A support plate is fixed at the rear end of the last support block. The top of the support plate is processed into an arc shape. A heightening block is arranged at the top of the last support block. The whole support block matches the shape of the bottom of the front part of the diesel generator set.

[0007] In this way, the supporting block plays a role in fixedly connecting a pair of side frames, increasing the structural strength of the entire base. Moreover, since the generator part in the diesel generator is exactly located at the front section of the base, the supporting block, the supporting plate, the connecting plate and the heightening block are arranged according to the concave and convex surfaces of the generator's outer shape.

[0008] As a further improvement of the present utility model, the fixing structure includes two fixing seats, and limiting blocks are arranged on the outer side surfaces of the fixing seats.

[0009] In this way, the installation structures on both sides of the generator part of the diesel generator are connected to the fixing seats by bolts, and the limiting blocks can play a limiting role, enabling the generator part and the fixing seats to be quickly and successfully matched, and avoiding large - scale deviations.

[0010] As a further improvement of the present utility model, the positioning structure includes two positioning seats, positioning grooves are formed on the positioning seats, and positioning inserts are provided to match the positioning grooves.

[0011] In this way, the positioning inserts are connected to the installation lugs on both sides of the diesel engine of the diesel generator by bolts, and the installation lugs just buckle on the positioning inserts. The positioning inserts are then matched with the positioning grooves and can be inserted into the positioning grooves exactly, and are fixed to the positioning grooves by welding. On the one hand, it can realize the rapid assembly of the diesel generator and the base, and on the other hand, the positioning seats can bear the diesel engine.

[0012] As a further improvement of the present utility model, the through - mounting structure includes five groups of screw holes, each group of screw holes is formed on the inner side surface of the side frame, and five groups of installation holes are formed on the outer side surface of the side frame, and one group of installation holes is directly opposite to one group of screw holes.

[0013] In this way, bolts can be passed through the installation holes into the screw holes and then screwed and fixed to the lower part of the diesel engine part of the diesel generator. Since the installation holes are relatively large and the side frame is a hollow structure, the hand together with the wrench can be extended into the installation holes to screw the bolts, which is convenient for installation.

[0014] As a further improvement of the present utility model, reinforcing plates are arranged on the inner side surface of the rear half section of the side frame. The reinforcing plates are also provided with five groups of screw holes, which correspond to the five groups of screw holes formed on the inner side of the side frame one by one.

[0015] In this way, the reinforcing plates can, on the one hand, increase the structural strength of the side frame, and on the other hand, fill the gap between the inner side surface of the side frame and the diesel generator, thus avoiding the deformation of the side frame caused by the tightening of the bolts.

[0016] As a further improvement of the present utility model, a reinforcing folding plate is arranged on the side frame between the front - most positioning seat and the adjacent fixing seat, and a cut is formed at the bending part of the reinforcing folding plate.

[0017] On the one hand, this increases the structural strength of the frame, and on the other hand, the cutouts are used to match the external shape structure of the diesel generator, preventing this part of the diesel generator from being unable to be assembled onto the base.

Detailed Embodiment

[0023] The present utility model will be further described below with reference to the drawings:

[0024] As Figures 1-4 shown, a rigid base for a high-power diesel generator includes a pair of frames 4. A support structure is connected between the front sections of the frames 4. A fixing structure is provided at the top of the front section of the frame 4. A positioning structure is provided on the rear half section of the frame 4. A through-mounted structure is provided on the rear half section of the frame 4.

[0025] The support structure includes four support blocks 13. Both ends of the support blocks 13 are fixedly connected to the frame 4. The latter three support blocks 13 are fixedly connected side by side. A connecting plate 8 is connected between the bottom of the foremost support block 13 and the adjacent support block 13. A support plate 11 is fixed to the rear end of the last support block 13. The top of the support plate 11 is processed into an arc shape. A heightening block 12 is provided at the top of the last support block 13. The entire support block 13 matches the external shape of the bottom of the front part of the diesel generator 17 group.

[0026] The fixed structure includes two fixed seats 14, and limit blocks 9 are arranged on the outer side surfaces of the fixed seats 14. The positioning structure includes two positioning seats 1, positioning grooves 5 are formed in the positioning seats 1, and positioning inserts 18 are provided to match the positioning grooves 5. The mounting structure includes five groups of screw holes 2, each group of screw holes 2 is formed in the inner side surface of the frame 4, and five groups of mounting holes 10 are formed in the outer side surface of the frame 4, and one group of mounting holes 10 is aligned with one group of screw holes 2. A reinforcing plate 3 is arranged on the inner side surface of the rear half section of the frame 4, and the reinforcing plate 3 is also provided with five groups of screw holes 2, which correspond to the five groups of screw holes 2 formed in the inner side of the frame 4 one by one. A reinforcing folding plate 6 is arranged on the frame 4 between the foremost positioning seat 1 and the adjacent fixed seat 14, and a notch 7 is formed at the bending part of the reinforcing folding plate 6.

[0027] In the present utility model, the diesel generator 17 is simply referred to as the diesel engine generator. In order to reduce the actual assembly height, the lower part of the diesel engine generator needs to sink into the base, that is, between a pair of frames 4. Therefore, the lower parts of all parts of the diesel engine generator need to contact the base. Thus, the entire frame 4 and its attached structures are all matched with the shape of the diesel engine generator.

[0028] The main body of the diesel engine generator is mainly the generator 17 and the diesel engine 16. The diesel engine 16 is located in the rear half section of the frame 4, and the generator 17 is located in the front half section of the frame 4. The outer shape of the generator 17 is cylindrical, and its actual height is lower than that of the diesel engine 16. And an oil tank 15 is provided for the diesel engine, and the oil tank 15 is located at the bottom of the diesel engine 16. In order to reduce the overall height of the assembled diesel engine generator, the oil tank 15 needs to extend downward out of the frame 4. In this way, the supporting structure for fixedly connecting the frame 4 can only be arranged in the front half section of the frame 4. At the same time, in order to enhance the overall strength of the base and reduce the deformation caused by welding, a reinforcing folding plate 6 is welded on the frame 4 between the positioning seat 1 and the adjacent fixed seat 14, and both ends of the three support blocks 13 arranged side by side are welded to the reinforcing folding plate 6.

[0029] Since there is a convex structure 19 at the rear of the generator 17, in order to prevent the convex structure 19 from squeezing and colliding with the lower part of the generator 17 and the support blocks 13, for the outer shape of the generator 17, the three support blocks 13 are arranged side by side, and the fourth and the third are connected by a connecting plate 8. A heightening block 12 is added to the first support block 13, and both ends of the heightening block 12 are welded to the reinforcing folding plate 6. A fixed structure for cooperating with the fixed seat 14 on the front section of the frame 4 is arranged on the outer periphery of the generator 17, and the two are fixedly connected by bolts. Since the reinforcing folding plate 6 itself has a certain thickness, a notch 7 is formed at the front part of the reinforcing folding plate 6 to avoid interference with the convex structure 19 through the notch 7.

[0030] The positioning insert block 18 is bolted to the mounting lugs 20 on both sides of the diesel engine 16, and the mounting lugs 20 just fit over the positioning insert block 18. The positioning insert block 18 is matched with the positioning slot 5 and can be inserted into the positioning slot 5 exactly, and is fixed to the positioning slot 5 by welding. On the one hand, it can realize the rapid assembly of the diesel generator and the base, and the positioning seat 1 can also bear the diesel engine 16. To better fix the diesel engine 16, bolts are inserted into the mounting holes 10, passed through the screw holes 2 on the reinforcing plate 3 and assembled with the screw holes 2 on the diesel engine 16. Since the mounting holes 10 are opened larger and the frame 4 is of a hollow structure, the hand and the wrench can be inserted into the mounting holes 10 together to screw the bolts, which is convenient for installation. The reinforcing plate 3 can increase the structural strength of the frame 4 on the one hand and fill the gap between the inner side of the frame 4 and the diesel generator on the other hand, so as to avoid the deformation of the frame 4 after the bolts are tightened.

[0031] After the assembly is completed, it is equivalent to the base sleeving the lower part of the diesel generator. The oil tank 15 extends downward from the base. In this way, when transporting, the diesel generator together with the base is placed on the bracket. The rear half of the bracket is hollow and used to accommodate the oil tank 15. In this way, the bracket, the base and the diesel generator form a whole. The actual height of this whole is only a little larger than the height of the diesel generator itself. Therefore, the height of the container used to transport the diesel generator is effectively reduced, thus reducing the transportation cost. Moreover, the main body of the base itself is a pair of frames 4 and the supporting structure, and its material consumption is greatly reduced, and the weight is also effectively reduced, so that the manufacturing cost is greatly reduced.

[0032] The utility model is not limited to the above embodiments. Based on the technical solutions disclosed in the present disclosure, those skilled in the art can make some substitutions and deformations to some technical features without creative labor according to the disclosed technical content, and these substitutions and deformations are all within the protection scope of the utility model.
