Description

Technical Field

[0001] The present invention relates to the technical field of generators, and in particular to a generator set protection structure and a generator set. Background Art

[0002] Portable generators are temporary power supply equipment, which are mainly divided into two types: open-frame generators and silent (enclosed) generators. Among them, the generator set of the open-frame generator is installed as a whole on a frame-type rack, through which the generator set is supported and protected.

[0003] During transportation or handling, open-frame generators may be at risk of falling, especially high-power generators. In the prior art, the generator set is only supported on the frame by shock-absorbing supports. Since the shock-absorbing supports are made of rubber, when a fall occurs, the shock-absorbing supports will deform in different directions. Once the degree of deformation exceeds the allowable range, the generator set will contact and collide with the frame or other related supporting components, and the frame will also collide with the ground. During the collision, under the action of force, it is easy to cause damage to the generator set. In order to solve the above problems, the present invention proposes a generator set protection structure. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, one of the objects of the present invention is to provide a generator set protection structure to address the problem that the generator set may be damaged due to falling. The second object of the present invention is to provide a generator set using the above-mentioned generator set protection structure.

[0005] The technical solution adopted by the present invention is as follows: A generator set protection structure comprises a frame, to which a connecting bracket is detachably connected. The generator set is supported on the frame by the connecting bracket and a shock-absorbing support during transportation, and is supported on the frame by the shock-absorbing support when not transported.

[0006] Compared with the prior art, the present invention has the following beneficial effects: 1. When the generator is not in use, especially during transportation or handling, the connecting bracket is installed on the frame. When the generator set is in use, the connecting bracket can be removed. The present invention sets the connecting bracket as a detachable structure, so that the connecting bracket can be removed when the generator set is in use. At this time, the generator set is connected to the frame through a shock-absorbing support, and the shock-absorbing support can be used to reduce the vibration of the generator set to ensure the stability of the generator set when in use.

[0007] 2. By installing the connecting bracket on the frame during transportation or handling, since the frame and the generator set are now connected through a shock-absorbing support, the generator set is prone to move during transportation or falling, thereby causing collisions between the generator set and other related components. The solution of the present invention can install the connecting bracket during transportation, so that the generator set can be hard-connected to the frame to avoid movement of the engine, thereby effectively avoiding the problem of damage to the generator set caused by collision due to movement.

[0008] 3. In the prior art, in order to better protect the generator set, especially in the process of transportation or handling to cope with the collision of falling, the frame pipes or plates usually used are thicker, which not only increases the weight of the whole machine, but also increases the cost. The solution of the present invention can avoid the collision between structures by cleverly setting up a detachable connection bracket. The connection bracket can be used as an additional part to increase the overall support strength. There is no need to use thicker pipes or thicker plates, which can minimize the manufacturing cost and reduce waste. It can also reduce the overall weight of the generator set, which is conducive to the lightweight design of the generator set.

[0009] As a preferred embodiment of the present invention, the frame is provided with two parallel arranged cross beams, two reinforcing beams are fixed between the two cross beams, a mounting plate is provided at the lower part of the engine, the shock absorbing support is installed between the cross beam and the mounting plate, and the connecting bracket is locked and connected to the reinforcing beam and the mounting plate by bolts respectively.

[0010] The reinforcing beam provided between the two beams of the present invention can not only install the connecting bracket, but also form the two beams into a whole. The reinforcing beam can effectively disperse the load on the beam, improve the supporting strength and stability of the entire bottom, and improve the bearing capacity of the beam, which can solve the problems of insufficient bearing strength and uneven force of conventional supporting structures.

[0011] As a preferred embodiment of the present invention, the reinforcing beam includes a vertical section and a horizontal section bent inward at the lower part of the vertical section, two connecting ear plates for connecting to the connecting bracket are arranged on the upper side of the vertical section, the edges of the two connecting ear plates and the upper side of the vertical section are folded inward, a reinforcing rib is formed at the corner between the vertical section and the horizontal section, and a plurality of lightening holes are opened on the vertical section.

[0012] In the present invention, the horizontal section of the reinforcing beam that is bent inwardly and the edge that is folded inwardly can improve the bending resistance of the reinforcing beam, so that the overall structure has higher strength and rigidity and improves the support stability; by opening a plurality of lightening holes on the reinforcing beam, the weight of the reinforcing beam can be reduced, and by providing reinforcing ribs at the corners between the horizontal plate and the vertical plate of the reinforcing beam, the corner strength can be enhanced, the stress concentration at the corner position can be reduced, the structural strength can be further improved, and the support stability can be improved.

[0013] As a preferred embodiment of the present invention, mounting grooves are provided at the positions of the two opposite sides of the two cross beams corresponding to the positions of the reinforcing beams, and the two ends of the reinforcing beams are inserted into the mounting grooves for fixing. The present invention can increase the connection area between the reinforcing beam and the cross beam by inserting the two ends of the reinforcing beam into the mounting grooves for fixing, thereby making the connection more stable, and this embedded fixing can embed part of the reinforcing beam into the cross beam, thereby enhancing the strength and stability of the overall structure.

[0014] As a preferred embodiment of the present invention, the connecting bracket includes a trapezoidal connecting plate with a hole in the middle and the edges of the hole and both sides of the connecting plate are folded outward, and the inner side of the lower part of the connecting plate is tightly attached to the outer sides of the two connecting ear plates.

[0015] In this solution, the connecting bracket adopts a trapezoidal symmetrical structure. The trapezoidal structure has good stability, can evenly disperse the load, and effectively improves the supporting effect. By opening a hole in the middle of the connecting plate, it can not only save materials and reduce costs, but also reduce weight. By folding the edges of the hole and the two sides of the connecting plate outward, the bending resistance of the connecting plate can be improved. The folding direction is outward, which is opposite to the folding direction of the edges of the two connecting ear plates. The connecting plate and the connecting ear plate can be tightly fitted to increase the contact area between the connecting plate and the connecting ear plate. The increase in contact area can increase the friction between the connecting plate and the connecting ear plate, making the connection more stable and not easy to loosen, thereby improving the stability of the connection.

[0016] As a preferred embodiment of the present invention, the mounting plate is bent upward on one side close to the connecting plate to form a first bent plate, the outer side of the first bent plate is tightly attached to the inner side of the upper part of the connecting plate, and the top of the connecting plate is bent inward to form a limiting plate, and the lower end surface of the limiting plate is abutted against the first bent plate.

[0017] In this solution, when the first bent plate is connected to the upper part of the connecting plate, the first bent plate and the connecting plate are tightly attached, which not only makes the connection more stable, but also can laterally limit the mounting plate and the generator set. The limiting plate on the top of the connecting plate is abutted against the upper side of the first bent plate, and can also vertically limit the mounting plate and the generator set to prevent vertical movement. By vertically and laterally limiting the mounting plate and the generator set, the stability of the connection can be further ensured and the stability of the overall structure can be improved.

[0018] As a preferred embodiment of the present invention, local reinforcement plates are installed on both sides of the bottom of the frame, and the local reinforcement plates extend toward both ends of the frame at a position close to the center of gravity of the engine unit.

[0019] In the prior art, in order to protect the generator set, the pipe material used for the frame is relatively thick as a whole. This not only increases the cost, but also greatly increases the overall weight of the machine. In the present invention, local reinforcement plates are installed in the local areas where the stress on the frame is more concentrated for sectional reinforcement, and the overall pipe thickness of the frame is reduced, which not only ensures the structural strength, but also reduces the cost and lightens the overall weight.

[0020] As a preferred embodiment of the present invention, a first bolt is provided between the upper part of the connecting plate and the first bending plate, and second bolts are provided between the two sides of the lower part of the connecting plate and the two connecting ear plates. The three connection points on the connecting plate of the present invention form a triangle, and the triangular structure is more stable.

[0021] As a preferred embodiment of the present invention, the cross-section of the cross beam is in a "ji" shape. The cross beam adopts a "ji" shaped beam. The "ji" shaped beam has been folded multiple times, has stronger bending resistance, stronger bearing capacity, and can reduce the wall thickness under the same load-bearing capacity, saving costs.

Detailed Embodiments

[0025] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0026] In the description of the present application, the terms "top", "bottom", "one end", "one side", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on the present application.

[0027] Example 1 See also Figure 1 and Figure 2 As shown, this embodiment discloses a generator set protection structure and a generator set using the protection structure. The generator set 8 protection structure includes a frame 1, the frame 1 is located outside the generator set 8, two parallel beams 2 are welded on the frame 1, and two parallel reinforcing beams 3 are welded between the two beams 2. Through the two reinforcing beams 3, the two beams 2 can be connected to form a whole, so as to effectively disperse the load on the beams 2, thereby enhancing the strength of the bottom support and improving the bearing capacity and stability of the beams 2.

[0028] Two rollers 10 are installed at the bottom of the frame 1 to facilitate the movement of the generator, wherein the lower side of the cross beam 2 away from the roller 10 is detachably connected to two legs 9, and the two legs 9 and the two rollers 10 can be supported on the ground. Specifically, the cross beam 2 includes a straight portion 21, both sides of the straight portion 21 are bent downward to form a first bent portion 22, and the lower sides of the two first bent portions 22 are bent outward to form a second bent portion 23, wherein the cross beam 2 without the legs 9 is folded upward at the second bent portion 23 away from the reinforcing beam 3, see Figure 8 As shown, the cross section is in the shape of a Chinese character "J". After being folded for many times, the Chinese character "J" beam has a stronger bending resistance. It not only has a stronger load-bearing capacity, but also can reduce the wall thickness under the same load-bearing condition, thus saving costs. The second bending portions 23 on the opposite sides of the two cross beams 2 are provided with mounting grooves 231 at positions corresponding to the reinforcing beams 3. The reinforcing beams 3 include a vertical section 31 and a horizontal section 32 bent inwardly at the lower part of the vertical section 31. Figure 3As shown, both ends of the vertical section 31 of the reinforcing beam 3 are inserted into the installation groove 231, and the upper side of the horizontal section 32 of the reinforcing beam 3 is against the second bending portion 23 of the cross beam 2. By inserting both ends of the reinforcing beam 3 into the installation groove 231 and making the horizontal section 32 against the second bending portion 23, the connection area between the reinforcing beam 3 and the cross beam 2 can be increased, thereby making the connection more stable. In addition, this embedded fixation can embed part of the reinforcing beam 3 into the cross beam 2, thereby enhancing the strength and stability of the overall structure. For the installation of the support leg 9, see Figure 7 As shown, there are two wing plates 91 on both sides of the top of the support leg 9, and the two wing plates 91 are respectively overlapped on the lower sides of the two second bending portions 23 of the corresponding cross beam 2 and locked by bolts. In one of the support legs 9, the horizontal section 32 of the reinforcing beam 3 is clamped between the wing plate 91 and the second bending portion 23, so that the support leg 9, the reinforcing beam 3 and the cross beam 2 are connected to disperse the load.

[0029] See also Figure 2 , Figure 4 and Figure 5 As shown, two mounting plates 7 are installed at the lower part of the generator set 8 corresponding to the two reinforcing beams 3, and a shock absorbing assembly is installed between the mounting plates 7 and the cross beam 2. The shock absorbing assembly includes four shock absorbing supports 6. A shock absorbing support 6 is installed at both ends of the two mounting plates 7. Each mounting plate 7 is installed between the two cross beams 2 through the shock absorbing support 6. A connecting bracket is detachably connected between the corresponding reinforcing beam 3 and the mounting plate 7. When the generator set is transported, it is supported on the frame by the connecting bracket and the shock absorbing support 6. Specifically, two connecting ear plates 311 for connecting with the connecting bracket are integrally formed on the upper side of the vertical section 31 of the reinforcing beam 3. The edges of the two connecting ear plates 311 and the upper side of the vertical section 31 are folded inward to improve the bending resistance of the reinforcing beam 3. A reinforcing rib 33 is formed at the corner between the vertical section 31 and the horizontal section 32 to enhance the corner strength and reduce the stress concentration at the corner position. A plurality of lightening holes 312 are opened on the vertical section 31 to reduce the weight of the reinforcing beam 3. The connecting bracket includes a trapezoidal connecting plate 4, a hole is opened in the middle of the connecting plate 4, and the edges of the hole and both sides of the connecting plate 4 are folded outwards, and the two sides of the lower part of the connecting plate 4 are tightly attached to the two connecting ear plates 311 and locked by a second bolt. The present invention can not only save materials and reduce costs by opening a hole in the middle of the connecting plate 4, but also reduce weight; by folding the edge of the connecting plate 4, the bending resistance of the structure can be enhanced and the strength can be improved. At the same time, the folding direction of the edge of the connecting plate 4 is outward, and the folding direction of the edges of the two connecting ear plates 311 is inward. This setting can make the connecting plate 4 and the connecting ear plates 311 fit tightly, so as to increase the contact area between the connecting plate 4 and the connecting ear plates 311. The increase in the contact area can increase the friction between the connecting plate 4 and the connecting ear plates 311, so that the connection is more stable and not easy to loosen, and the stability of the connection is improved.

[0030] The mounting plate 7 is bent upward on one side near the connecting plate 4 to form a first bent plate 71, and the other side is bent downward to form a second bent plate 72. The first bent plate 71 and the second bent plate 72 can both enhance the bending resistance of the mounting plate 7 and improve the load-bearing capacity of the plate. In addition, the middle part of the first bent plate 71 is tightly attached to the upper part of the connecting plate 4 and connected by the first bolt. The first bent plate 71 is tightly attached to the connecting plate 4, which not only makes the connection more stable, but also can limit the mounting plate 7 and the generator set 8 laterally to prevent lateral movement. Figure 6 As shown, the top of the connecting plate 4 is bent inward to form a limiting plate 41, and the lower end surface of the limiting plate 41 is against the first bent plate 71. The present invention provides the limiting plate 41, which can not only serve as a bending portion to improve the strength of the connecting plate 4, but also can vertically limit the mounting plate 7 and the generator set 8 to prevent vertical movement. By vertically and laterally limiting the mounting plate 7 and the generator set 8, the stability of the connection can be further ensured, and the stability of the overall structure can be improved.

[0031] In the present invention, when the generator is not in use, especially during transportation or handling, the connecting bracket is installed on the frame 1. Since the generator set 8 is installed on the mounting plate 7, a shock-absorbing support 6 is installed between the mounting plate 7 and the crossbeam 2. If the shock-absorbing support itself is elastically deformed during transportation or falling, the generator set 8 will be caused to move. Once the deformation range is exceeded, it is easy to cause a collision between the generator set 8 and other related components. The present invention can hard connect the generator set 8 to the frame 1 by cleverly installing the connecting bracket during transportation to avoid the generator set 8 from moving, thereby effectively avoiding the problem of damage to the generator set 8 caused by collision due to movement, thereby protecting the generator set 8. When the generator set 8 is in use, the connecting bracket is removed, and the generator set 8 is connected to the frame 1 through the shock-absorbing support 6, so that the shock-absorbing support 6 can be used to reduce the vibration of the generator set 8 to ensure the stability of the operation of the generator set. This clever setting can not only well protect the generator set 8 and related components, but also save materials and reduce the weight of the whole machine. In the prior art, in order to better protect the generator set 8, especially in the process of transportation or handling to cope with the collision of falling, the frame 1 is usually made of thicker pipes or plates. Such a setting not only increases the weight of the whole machine, but also increases the cost. The solution of the present invention can avoid the collision between structures by setting a detachable connecting bracket. The connecting bracket can be used as an additional part to increase the overall support strength. There is no need to use thicker pipes or thicker plates, which can minimize the manufacturing cost and reduce waste. It can also reduce the overall weight of the generator set 8, which is conducive to the lightweight design of the generator set 8.

[0032] Furthermore, when a fall or collision occurs, the rack 1 will also collide with the ground, which may easily cause damage. Therefore, local reinforcement plates 5 are installed on both sides of the bottom of the rack 1, see Figure 1 As shown, the local reinforcement plate 5 extends to both ends of the frame 1 at a position close to the center of gravity of the generator set. In the prior art, in order to protect the generator set 8, the pipe used in the frame 1 is thicker as a whole, which is not only costly, but also greatly increases the weight of the whole machine. The present invention installs the local reinforcement plate 5 in the local area where the force of the frame 1 is more concentrated, and performs partition reinforcement, while the overall pipe thickness of the frame 1 is reduced, which not only ensures the structural strength, but also reduces the cost and the overall weight.

[0033] Example 2 The length of the reinforcing beam 2 is the distance between the two beams 2 on the frame 1. To achieve assembly, the distance between the two beams 2 on the frame 1 is fixed. Therefore, before welding the two beams 2 to the frame 1, it is necessary to locate the distance between the two beams 2 in advance. In the prior art, an additional positioning tool is used to locate the positions of the two beams 2 before welding. The two parallel reinforcing beams 3 provided in the present invention can play a positioning role during assembly. After welding one beam 2, two reinforcing beams 3 are installed in sequence. The free end connection line of the two reinforcing beams 3 is the position of the other beam 2. In this assembly welding process, no additional positioning tool is required to install and position, which not only saves the cost of additional equipment, but also saves positioning time. Therefore, the reinforcing beam 3 in the present invention can not only install the connecting bracket, but also form the two beams 2 into a whole to disperse the load on the beam 2, improve the support strength and stability of the entire bottom, and improve the bearing capacity of the beam 2. At the same time, it can also play a positioning role, which can improve assembly efficiency and save costs.

[0034] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
