Description

Technical Field

[0001] This utility model belongs to the technical field of power generation equipment support devices, and in particular, relates to an engine bracket for generator sets that facilitates the replacement of shock-absorbing pads. Background Technology

[0002] Diesel generators have advantages such as high power, good stability, and low operating costs, and are widely used in various fields such as industry, agriculture, commerce, and households. A diesel generator typically consists of a diesel engine, a generator set, and a support assembly that supports and fixes the diesel engine and generator set. The support assembly bears the weight of the diesel generator and dynamic impact loads, and can reduce vibration and noise during the operation of the diesel engine.

[0003] Currently, rubber vibration damping pads are typically installed between the diesel engine and the support bracket to buffer and reduce vibrations generated during diesel generator operation. However, these rubber damping pads wear out or age over time, requiring periodic replacement. Because the diesel engine presses the rubber damping pads tightly against the support bracket, the engine must first be removed from the bracket and then lifted using lifting equipment before the worn or aged rubber damping pads can be replaced. This makes it difficult to replace the worn or aged rubber damping pads quickly and conveniently. Utility Model Content

[0004] Based on the aforementioned problems in the prior art, the purpose of this utility model embodiment is to provide an engine bracket for generator sets that facilitates the replacement of vibration damping pads, thereby solving the technical problem in the prior art where, after the rubber vibration damping pads located between the diesel engine and the bracket are worn or aged, the diesel engine presses the rubber vibration damping pads tightly onto the bracket, making it difficult to quickly and conveniently replace the worn or aged rubber vibration damping pads.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide an engine bracket for a generator set that facilitates the replacement of shock-absorbing pads, comprising: The support assembly includes a fixed bracket and a plurality of movable brackets that can be moved up and down on the fixed bracket. Each movable bracket includes a horizontal support plate for being fixedly connected to the support base plate of the diesel engine and a support shaft connected to the horizontal support plate. The fixed bracket is provided with a plurality of first shaft holes that are perpendicular to the horizontal plane at intervals. One end of each support shaft away from the horizontal support plate is slidably inserted into the corresponding first shaft hole. The shock absorption assembly includes a plurality of rubber shock absorption pads detachably mounted on the fixed bracket, and the support base plate of the diesel engine is supported on each of the rubber shock absorption pads; A lifting assembly for lifting the support base plate of the diesel engine upwards to separate the support base plate of the diesel engine from the upper surface of the rubber shock-absorbing pad; and The lifting assembly is used to lift the diesel engine above the fixed bracket after the lifting assembly lifts the support base plate of the diesel engine upward. The lifting assembly includes multiple rotating shafts rotatably mounted on the fixed bracket, and cams fixedly connected to both ends of each rotating shaft, with equal spacing between adjacent rotating shafts.

[0006] Furthermore, the shock absorption assembly also includes shock absorption springs sleeved on each of the support shafts, with the bottom end of each shock absorption spring abutting against the fixed bracket and the top end of each shock absorption spring abutting against the bottom surface of the corresponding horizontal support plate.

[0007] Furthermore, each of the first shaft holes is a stepped hole, and the sliding groove of one end of the support shaft away from the horizontal support plate is inserted into the lower small hole of the stepped hole. The bottom of the shock-absorbing spring is accommodated in the upper large hole of the stepped hole, and the bottom end of the shock-absorbing spring abuts against the stepped surface of the stepped hole.

[0008] Furthermore, the fixed bracket includes two parallel and spaced first crossbeams, and a plurality of second crossbeams connected at both ends to the two first crossbeams respectively. Each first crossbeam has first shaft holes equally spaced along its length direction, and the support shaft of each movable bracket is slidably inserted into the corresponding first shaft hole.

[0009] Furthermore, multiple second crossbeams are arranged parallel to each other and spaced apart, with equal spacing along the length direction of the first crossbeam. Each second crossbeam has a second shaft hole extending through it along its length direction, and each rotating shaft is rotatably disposed in the corresponding second shaft hole.

[0010] Furthermore, the support base plate of the diesel engine is provided with an arc-shaped positioning groove that matches the arc protrusion of the cam.

[0011] Furthermore, the lifting assembly includes multiple jacks, which are equally spaced apart on the outside of the fixed space.

[0012] Furthermore, the jack and the cam are offset from each other.

[0013] Furthermore, the rubber shock-absorbing pad is offset from the movable bracket, and a shock-absorbing spring is sleeved on the support shaft of the movable bracket.

[0014] Furthermore, each of the horizontal support plates is provided with a first bolt hole, and the support base plate of the diesel engine is provided with a second bolt hole at the position corresponding to the first bolt hole. The generator set engine bracket for easy replacement of the shock absorber pad also includes a plurality of fastening bolts for fastening the horizontal support plate to the support base plate of the diesel engine.

[0015] Compared with the prior art, one or more technical solutions in the embodiments of this utility model have at least one of the following beneficial effects: The generator set engine bracket for easy replacement of vibration damping pads in this embodiment of the invention only requires lifting the diesel engine's support base plate upwards using a lifting assembly, and then using multiple cams to assist jacks in lifting the diesel engine above the fixed bracket. This creates a certain gap between the diesel engine's support base plate and the upper surface of the rubber vibration damping pad, thus eliminating the need to remove the diesel engine from the fixed bracket. This allows for convenient and quick removal of worn or aged rubber vibration damping pads and easy and quick installation of new rubber vibration damping pads onto the fixed bracket. After installing the new rubber vibration damping pads on the fixed bracket, simply rotating the cams to remove the lifting effect on the diesel engine's support base plate and releasing the lifting force of the jacks allows the diesel engine's support base plate to press down and support itself on the replaced rubber vibration damping pads under the diesel engine's own weight, thereby facilitating the quick and easy replacement of the rubber vibration damping pads.

[0022] Please refer to the following: Figures 1 to 8 The following describes the generator set engine bracket with easily replaceable shock-absorbing pads provided by an embodiment of this utility model. Please refer to further details. Figure 1 , Figure 2 and Figure 3The generator set engine bracket for easy replacement of shock-absorbing pads provided in this embodiment of the utility model includes a support assembly 1, a shock-absorbing assembly 2, a lifting assembly 3, and a support assembly 4. The support assembly 1 includes a fixed bracket 11 and a plurality of movable brackets 12 that are movably mounted on the fixed bracket 11. Each movable bracket 12 includes a horizontal support plate 121 and a support shaft 122 connected to the horizontal support plate 121. The horizontal support plate 121 is used to fixably connect to the support base plate 51 of the diesel engine 5. A plurality of first shaft holes 113 are spaced apart on the fixed bracket 11. The axial direction of each first shaft hole 113 is perpendicular to the horizontal plane. One end of each support shaft 122 facing away from the horizontal support plate 121 is slidably inserted into the corresponding first shaft hole 113, so that each movable bracket 12 can be movably mounted on the fixed bracket 11. The vibration damping assembly 2 includes multiple rubber damping pads 21, which are detachably mounted on the fixed bracket 11. The support base plate 51 of the diesel engine 5 is supported on each rubber damping pad 21, thereby allowing the diesel engine 5 to be supported on the fixed bracket 11 via the rubber damping pads 21. The vibrations generated by the diesel engine 5 during operation can be damped and buffered by the rubber damping pads 21. The lifting assembly 3 is used to lift the support base plate 51 of the diesel engine 5 upwards, so that the support base plate 51 of the diesel engine 5 is separated from the upper surface of the rubber damping pads 21, and a certain distance is maintained between the support base plate 51 of the diesel engine 5 and the upper surface of the rubber damping pads 21. This prevents the support base plate 51 of the diesel engine 5 from pressing tightly against the rubber damping pads 21 under the weight of the diesel engine 5, thus facilitating the replacement of worn or aged rubber damping pads 21. The lifting assembly 4 is used to assist the jack 31 of the lifting assembly 3 in lifting the diesel engine 5 above the fixed bracket 11 after the lifting assembly 3 lifts the support base plate 51 of the diesel engine 5 upwards. This enhances the stability of the diesel engine 5 when replacing the rubber damping pad 21, thereby improving the safety of the rubber damping pad 21 replacement operation. The lifting assembly 4 includes multiple rotating shafts 41 rotatably mounted on the fixed bracket 11, and cams 42 fixedly connected to both ends of each rotating shaft 41. The spacing between adjacent rotating shafts 41 is equal.

[0023] The generator set engine bracket provided in this embodiment of the utility model, which facilitates the replacement of the vibration damping pad, allows for easy replacement of the rubber vibration damping pad 21. Since the support base plate 51 of the diesel engine 5 is supported on the fixed bracket 11 by multiple movable support plates, it is only necessary to use the lifting assembly 3 to lift the support base plate 51 of the diesel engine 5 upward a short distance, so that the support base plate 51 of the diesel engine 5 is separated from the upper surface of the rubber vibration damping pad 21, thereby relieving the pressure of the support base plate 51 of the diesel engine 5 on the rubber vibration damping pad 21 due to the weight of the diesel engine 5. Then, by rotating the cams 42 at both ends of each rotating shaft 41, after the lifting assembly 3 lifts the support base plate 51 of the diesel engine 5 upward, the cams 42 assist the jack 31 in lifting the diesel engine 5 above the fixed bracket 11, thereby enhancing the stability of the diesel engine 5 when replacing the rubber vibration damping pad 21. At this time, there is a certain gap between the support base plate 51 of the diesel engine 5 and the upper surface of the rubber damping pad 21, so that the diesel engine 5 does not need to be removed from the fixed bracket 11 and can be easily and quickly removed from the worn or aged rubber damping pad 21. After the new rubber damping pad 21 is installed on the fixed bracket 11, it is only necessary to rotate the cams 42 at both ends of each rotating shaft 41 so that each cam 42 removes the lifting effect on the support base plate 51 of the diesel engine 5, and then release the lifting force of each jack 31 on the support base plate 51 of the diesel engine 5. At this time, under the action of the diesel engine 5's own weight, the support base plate 51 of the diesel engine 5 presses down on multiple movable brackets 12. The sliding engagement between the support shafts 122 of multiple movable brackets 12 and the corresponding first shaft holes 113 on the fixed bracket 11 can guide the support base plate 51 of the diesel engine 5 to press down stably and support it on the replaced rubber damping pad 21, thereby facilitating the replacement of the rubber damping pad 21.

[0024] Please refer to the following: Figure 2 , Figure 4 and Figure 8 In some embodiments, the shock-absorbing assembly 2 further includes shock-absorbing springs 22 sleeved on each support shaft 122, with the bottom end of each shock-absorbing spring 22 abutting against the fixed bracket 11 and the top end of each shock-absorbing spring 22 abutting against the bottom surface of the corresponding horizontal support plate 121. In this embodiment, the shock-absorbing springs 22 sleeved on each support shaft 122 provide shock absorption and buffering for the movable bracket 12, thereby improving the shock absorption and buffering effect on the diesel engine 5.

[0025] Please refer to the following: Figure 2 and Figure 4In some embodiments, each first shaft hole 113 is a stepped hole. The end of the support shaft 122 facing away from the horizontal support plate 121 is inserted into the lower small hole of the stepped hole via a sliding groove. The bottom of the damping spring 22 is housed in the upper large hole of the stepped hole, and the bottom end of the damping spring 22 abuts against the stepped surface of the stepped hole. In this embodiment, housing the bottom of the damping spring 22 in the upper large hole of the stepped hole enhances the damping and buffering effect of the damping spring 22.

[0026] Please refer to the following: Figure 5 , Figure 6 and Figure 8 In some embodiments, the fixed bracket 11 includes two parallel and spaced-apart first crossbeams 111 and a plurality of second crossbeams 112 connected at both ends to the two first crossbeams 111 respectively. Each first crossbeam 111 has first shaft holes 113 evenly spaced along its length direction, and the support shaft 122 of each movable bracket 12 is slidably inserted into the corresponding first shaft hole 113. In this embodiment, the first shaft holes 113 are evenly spaced along the length direction on each first crossbeam 111. By sliding the support shaft 122 of each movable bracket 12 into the corresponding first shaft hole 113, the movable brackets 12 are evenly distributed on each first crossbeam 111. This not only helps to improve the balance of force on the support base plate 51 of the diesel engine 5, but also enhances the stability of the lifting assembly 3 during the lifting process of the support base plate 51 of the diesel engine 5.

[0027] Please refer to the following: Figure 5 , Figure 6 and Figure 8 In some embodiments, multiple second crossbeams 112 are arranged parallel to each other and spaced apart, with equal spacing along the length of the first crossbeam 111. Each second crossbeam 112 has a second shaft hole 114 extending through it along its length, and each rotating shaft 41 is rotatably disposed in the corresponding second shaft hole 114. In this embodiment, rotatably mounting each rotating shaft 41 in the second shaft hole 114 of each second crossbeam 112 not only enhances the stability of the rotation of the rotating shaft 41, but also increases the supporting force of the cam 42 supporting the support base plate 51 of the diesel engine 5.

[0028] Please refer to the following: Figure 3 , Figure 5 and Figure 8In some embodiments, the support base plate 51 of the diesel engine 5 is provided with an arc-shaped positioning groove 52 that matches the arc-shaped protrusion 421 of the cam 42. When the cam 42 is rotated so that the arc-shaped protrusion 421 of the cam 42 engages in the arc-shaped positioning groove 52 on the support base plate 51 of the diesel engine 5, it can prevent the cam 42 from slipping off the support base plate 51 of the diesel engine 5 during the lifting of the diesel engine 5. This can improve the stability of the diesel engine 5 when replacing the rubber damping pad 21, thereby improving the safety of the rubber damping pad 21 replacement operation. After the rubber damping pad 21 is replaced, the support base plate 51 of the diesel engine 5 only needs to be lifted upward by the jack 31 to disengage the arc-shaped protrusion 421 of the cam 42 from the arc-shaped positioning groove 52 on the support base plate 51 of the diesel engine 5. Then the cam 42 can be rotated to remove the lifting effect of the cam 42 on the support base plate 51 of the diesel engine 5. It should be noted that in some other embodiments, in order to prevent the cam 42 from slipping off the support base plate 51 of the diesel engine 5 during the lifting of the diesel engine 5, a positioning pin or positioning clamp may be provided to position the cam 42 on the fixed bracket 11 to limit the position of the cam 42.

[0029] Please refer to the following: Figure 1 , Figure 2 and Figure 8 In some embodiments, the lifting assembly 3 includes a plurality of jacks 31, which are equally spaced on the outside of the fixed bracket, so that the plurality of jacks 31 can provide a lifting force evenly to the support base plate 51 of the diesel engine 5, thereby enabling the diesel engine 5 to be stably lifted to the position above the fixed bracket 11 and separated from the rubber shock-absorbing pad 21.

[0030] Please refer to the following: Figure 1 and Figure 3 In some embodiments, the jack 31 and the cam 42 are staggered, which enhances the force balance of the diesel engine 5 during the replacement of the rubber damping pad 21, allowing the diesel engine 5 to remain stably above the fixed bracket 11 and separated from the rubber damping pad 21. It should be noted that in other embodiments, the jack 31 can also be replaced by a lifting mechanism such as a cylinder or hydraulic cylinder.

[0031] Please refer to the following: Figure 1 and Figure 3 In some embodiments, the rubber damping pad 21 is offset from the movable bracket 12, and the support shaft 122 of the movable bracket 12 is fitted with a damping spring 22, which provides better buffering and damping effect for the vibration generated during the operation of the diesel generator.

[0032] Please refer to the following: Figure 4 , Figure 6 , Figure 7 and Figure 8 In some embodiments, each horizontal support plate 121 has a first bolt hole 123, and the support base plate 51 of the diesel engine 5 has a second bolt hole 53 corresponding to the first bolt hole 123. The generator set engine bracket for easy replacement of the shock absorber also includes a plurality of fastening bolts 6 for fastening the horizontal support plate 121 to the support base plate 51 of the diesel engine 5. In this embodiment, it is only necessary to align the second bolt hole 53 on the support base plate 51 of the diesel engine 5 with the first bolt hole 123 on each horizontal support plate 121, and then pass the fastening bolt 6 through the second bolt hole 53 and the first bolt hole 123 to achieve a fastening connection between the support base plate 51 of the diesel engine 5 and the horizontal support plate 121.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
