Description

Technical Field

[0001] This invention relates to the field of diesel generator set technology, specifically to a self-loading and unloading diesel generator set structure. Background Technology

[0002] Diesel generator sets are a type of backup power source with good overall performance. They can be used for emergency power supply in various important occasions such as communication, rescue, medical care, and military. The overall structure of diesel generator sets is large, with many internal electrical components and a heavy weight. It is inconvenient for manual handling. When transporting diesel generator sets, hoisting or lifting equipment is required to assist in loading and unloading the diesel generator set structure on the transport vehicle.

[0003] For example, patent CN214650647U discloses a diesel generator set transfer device that is easy to load and unload. The device includes a base and a protective shell. The inner wall of the base has a groove through which a push-pull rod passes. A first spring is installed on the outer side of the push-pull rod, and one end of the push-pull rod passes through a storage groove. A second spring is installed inside the storage groove, and a connecting rod is installed inside the second spring. A slot is provided inside the connecting rod, and casters are installed below the connecting rod. A platform is provided above the base, and a storage cavity is provided inside the platform. A buffer spring is installed inside the storage cavity, and a storage slot is connected above the buffer spring. A generator set is installed inside the storage slot. The protective shell is installed on the platform. This easy-to-load diesel generator set transfer device allows for convenient loading and unloading and provides protection.

[0004] For example, patent CN210733935U discloses a diesel generator assembly and unloading fixture, including a truck body. A driver's cab is fixedly connected to either side of the truck body. Two symmetrically arranged second hydraulic cylinders are respectively installed on the top of the truck body near the driver's cab and on the side away from the driver's cab. A first hydraulic cylinder is installed on the side of the second hydraulic cylinder away from the driver's cab. Both the first and second hydraulic cylinders are equipped with casters at their bottoms. A fixed frame is installed above the truck body, and three sets of support frames are installed at the bottom of the fixed frame. The three sets of support frames are fixedly connected to the tops of the first and second hydraulic cylinders respectively on the side away from the fixed frame. A sliding groove is opened at the center of the top of the truck body, and the sliding groove is perpendicular to the driver's cab. This device can automatically load and unload generator sets, avoiding the use of cranes for transportation, saving costs. Moreover, this product is simple and convenient to use, saves labor time, improves loading and unloading efficiency, and ensures stable and safe loading and unloading.

[0005] For example, patent CN218950407U discloses a diesel generator transport and loading / unloading device, which solves the current problem of inconvenient and rapid loading and unloading of diesel generator sets. It includes a base, with universal self-locking wheels fixedly installed near the four corners of the base's bottom. A fixing mechanism is installed on the top of the base to fix the diesel generator set. The fixing mechanism includes a placement plate located above the base. This invention, through the cooperation between movable plates and movable rods, as well as springs and a top plate, facilitates the rotation of the two movable plates to a vertical position, while simultaneously allowing the top plate to move downwards, enabling the two clamping plates to clamp and fix the diesel generator set. Simultaneously, the two movable plates can rotate to a horizontal position, allowing the positioning pin to insert into the positioning sleeve, thereby facilitating... The purpose is to release the fixing of the diesel generator set, thereby facilitating the rapid loading and unloading of the diesel generator set. In the existing process of loading, unloading and lifting, some diesel generator sets are prone to overall structural imbalance due to inconsistent drive force output, resulting in a tilt on one side. During loading and unloading, the tilt of the unit structure will cause instability during the lifting and unloading process. When the unit structure comes into contact with the ground or transport vehicle, the force will be uneven. When the unit structure lands, it is easy to be impacted and vibrated, which will damage the internal electrical components and affect the service life of the diesel generator set. In addition, when transporting the generator set on some bumpy roads, the transport vehicle does not have a structure to buffer the bumps to keep the generator set moving stably, which will cause the generator set to be bumped and vibrated during transportation, which can easily damage its internal electrical structure.

[0006] To address the aforementioned issues, there is an urgent need for innovative design based on the existing diesel generator set structure. Summary of the Invention

[0007] The purpose of this invention is to provide a self-loading and unloading diesel generator set structure to solve the problem mentioned in the background art that some diesel generator sets are prone to overall structural imbalance and tilting on one side during loading, unloading and lifting due to inconsistent driving force output. During loading and unloading, the tilt of the generator set structure will cause instability during the lifting and lowering of the equipment, uneven force when the generator set structure contacts the ground or transport vehicle, and vibration of the generator set structure, which will lead to damage to the internal electrical components and affect the service life of the diesel generator set.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a self-loading and unloading diesel generator set structure, including a chassis for mounting diesel generator components, a frame fixedly installed on the outside of the chassis, and supporting steel frames fixedly installed at the four corners of the frame; an upper pull rod and a lower pull rod are rotatably connected sequentially from top to bottom in the supporting steel frame, and rectangular columns are rotatably connected to the sides of the upper pull rod and the lower pull rod, and the upper pull rod and the lower pull rod are set at the same slope between the supporting steel frame and the rectangular columns, and a supporting upright is slidably fitted inside the rectangular column; a support mechanism is provided between the supporting upright and the rectangular column to maintain the balance of lifting and unloading the chassis, and the lifting and adjusting control of the supporting upright controls the autonomous extension and folding of the support mechanism.

[0009] Preferably, a protrusion is fixedly connected to the side of the pull rod, and a cylinder is rotatably connected to the supporting steel frame, with the output end of the cylinder rotatably connected to the protrusion; the cylinder is tilted and supported between the pull rod and the supporting steel frame.

[0010] Preferably, an electric telescopic rod is fixedly installed on the outside of the rectangular column, and the output end of the electric telescopic rod is fixedly connected to the supporting column; a guide groove is provided on the rectangular column, and a guide slide is slidably connected in the guide groove. The guide slide is fixedly connected to the supporting column, and the guide slide is engaged with the outside of the rectangular column.

[0011] Preferably, the support mechanism includes two sets of reinforcing support rods rotatably mounted on the outside of the support pole, the two sets of reinforcing support rods being vertically distributed; a positioning seat is rotatably mounted on the other end of the reinforcing support rod, and a caster wheel is rotatably mounted on the positioning seat.

[0012] Preferably, the support mechanism further includes a guide rod rotatably connected to the positioning seat, with a telescopic guide rod slidably connected to the end of the guide rod away from the positioning seat, and the telescopic guide rod rotatably connected to the guide slide; a limit spring is elastically connected between the telescopic guide rod and the guide rod.

[0013] Preferably, the support pole is provided with a power mechanism for driving the reinforcing support pole to rotate, and the support pole is provided with a self-locking mechanism for limiting the rotation angle of the reinforcing support pole.

[0014] Preferably, the power mechanism includes a side groove formed on the support pole, the position of the side groove being laterally corresponding to the position of the reinforcing support pole; a half gear is sleeved and fixed on the reinforcing support pole along its rotation axis, and the half gear is inserted through the side groove; the reinforcing support pole rotates downward to its maximum position, causing the universal wheel to contact the ground.

[0015] Preferably, a cylindrical rod is fixedly connected inside the rectangular column along the central axis, and the cylindrical rod extends through the interior of the supporting upright; a lifting rod is fixedly installed on the lower end face of the cylindrical rod, and racks are fixedly installed on both sides of the outer side of the lifting rod. The position of the racks corresponds to the position of the side grooves, and the racks are meshed with the half gears; the height of the upper end face of the lifting rod is lower than the height of the lower end face of the rectangular column.

[0016] Preferably, the self-locking mechanism includes a fixed frame fixedly installed on the support pole, and an elastic element is fixedly installed on the fixed frame; the elastic element is inclinedly connected to the fixed frame, and the end of the elastic element near the reinforcing support pole has an inclined angled structure.

[0017] Preferably, the reinforcing support rod has a slot, and the elastic element passes through the slot and engages with the reinforcing support rod for limiting connection, and the inclined angle above the elastic element elastically fits against the surface of the reinforcing support rod.

[0018] Compared with the prior art, the beneficial effects of the present invention are: the self-loading and unloading diesel generator set structure can push the rectangular column to move and unfold next to the frame through the operation cylinder, so that the rectangular column is supported on the four sides of the chassis and the frame. The operation of the electric telescopic rod pushes the support column to move and unfold under the rectangular column, so that the chassis and the frame can move upward, so as to realize the self-lifting and unloading operation of the chassis and the frame without the need for additional hoisting or lifting equipment.

[0019] Furthermore, a support mechanism is provided between the support pole and the rectangular column to maintain the balance of the chassis lifting and unloading. During the process of controlling the movement and unfolding of the support pole and the rectangular column, the reinforcing support rod is driven by force to rotate and unfold on the side of the support pole. The guide rod and telescopic guide rod connected between the positioning seat and the guide slide can extend and retract autonomously, and can also rotate and unfold autonomously. This allows the reinforcing support rod, guide rod, and telescopic guide rod to rotate and tilt to support the sides of the support pole and the rectangular column. The reinforcing support rod, guide rod, and telescopic guide rod are provided with support structures in both directions of the support pole and the rectangular column, which can maintain the stability of the four-way driving force output during the lifting and unloading of the chassis, so that the chassis can be lifted and unloaded as stably as possible.

[0020] A limit spring is elastically connected between the guide rod and the telescopic guide rod. This part of the structure can adjust itself elastically during the lifting and lowering of the chassis, which plays a buffering role in the lifting and lowering operation of the chassis, avoiding the chassis from colliding with the ground or transport vehicle due to excessive speed during lifting and lowering, and ensuring that the chassis can land smoothly.

[0021] Furthermore, the support pole is equipped with a power mechanism that drives the reinforcing support rod to rotate. When the support pole and the rectangular column are adjusted for height, the lifting rod and the rack in the rectangular column move up and down synchronously. The initial movement path of the rack is engaged with the half gear, which drives the half gear and the reinforcing support rod to rotate under the meshing transmission, thereby adjusting the angle at which the reinforcing support rod is connected to the side of the support pole.

[0022] The support pole is equipped with a self-locking mechanism that limits the rotation angle of the reinforcing support pole. When the reinforcing support pole is rotated and extended to the maximum angle, the rack and half gear move and separate, and the reinforcing support pole and the elastic element are elastically engaged, so that the extension angle of the reinforcing support pole is limited, and the reinforcing support pole is kept in the extended state connected to the support pole.

[0023] When transporting generator sets on bumpy roads, rectangular columns and support poles can be unfolded and placed on the outside of the generator set. The reinforcing support poles next to the support poles can be rotated and unfolded so that the casters are in contact with the ground. During the transportation process, the reinforcing support poles, guide poles and telescopic guide poles support the outside of the generator set, which can buffer the vibration force during transportation and keep the generator set stable during transportation.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1: Please refer to Figures 1-6 The present invention provides the following technical solution: a self-loading and unloading diesel generator set structure, including a chassis 1 for mounting diesel generator components, a frame 2 fixedly mounted on the outside of the chassis 1, and support steel frames 3 fixedly mounted at the four corners of the frame 2; an upper pull rod 4 and a lower pull rod 5 are rotatably connected from top to bottom in the support steel frame 3, and a rectangular column 6 is rotatably connected to the sides of the upper pull rod 4 and the lower pull rod 5, and the upper pull rod 4 and the lower pull rod 5 are set at the same slope between the support steel frame 3 and the rectangular column 6, and a support upright 7 is slidably sleeved inside the rectangular column 6; a support mechanism is provided between the support upright 7 and the rectangular column 6 to maintain the balance of lifting and unloading the chassis 1, and the lifting and adjusting control of the support upright 7 controls the support mechanism to extend and fold for storage.

[0042] Please see Figures 2-6A protrusion 51 is fixedly connected to the side of the pull rod 5, and a cylinder 52 is rotatably connected to the support steel frame 3. The output end of the cylinder 52 is rotatably connected to the protrusion 51. The cylinder 52 is tilted and supported between the pull rod 5 and the support steel frame 3.

[0043] Please see Figure 6 and Figure 7 An electric telescopic rod 8 is fixedly installed on the outside of the rectangular column 6, and the output end of the electric telescopic rod 8 is fixedly connected to the support column 7. A guide groove 61 is provided on the rectangular column 6, and a guide slide 62 is slidably connected in the guide groove 61. The guide slide 62 is fixedly connected to the support column 7, and the guide slide 62 is snapped onto the outside of the rectangular column 6.

[0044] Please see Figures 1-3 , Figures 7-9 The support mechanism includes two sets of reinforcing rods 9 rotatably mounted on the outside of the support pole 7, and the two sets of reinforcing rods 9 are vertically distributed; a positioning seat 10 is rotatably mounted on the other end of the reinforcing rod 9, and a caster wheel 11 is rotatably mounted on the positioning seat 10.

[0045] Please see Figures 1-3 , Figures 7-11 The support mechanism also includes a guide rod 12 rotatably connected to the positioning seat 10. The end of the guide rod 12 away from the positioning seat 10 is slidably connected to a telescopic guide rod 13. The telescopic guide rod 13 is rotatably connected to the guide slide 62. A limit spring 14 is elastically connected between the telescopic guide rod 13 and the guide rod 12.

[0046] When the control box 1 is lifted and unloaded autonomously, its lifting process is as follows: The operating cylinder 52 pushes the protrusion 51 away from the supporting steel frame 3. At this time, the lower pull rod 5 rotates between the supporting steel frame 3 and the rectangular column 6, causing the rectangular column 6 to move outward and unfold at the corner of the frame 2. During the outward movement of the rectangular column 6, the upper pull rod 4 also rotates and unfolds. The two sets of pull rods can keep the rectangular column 6 connected to the supporting steel frame 3 and unfolded stably. Then, the operating electric telescopic rod 8 pushes the supporting upright 7 to move up and down. The unfolding of the supporting upright 7 can lift the frame 2 and the control box 1 upward, thereby achieving the purpose of controlling the autonomous lifting of the control box 1.

[0047] When the control unit 1 is autonomously lifted and unloaded, its descent process is as follows: First, the transport platform at the rear of the transport vehicle is moved to below the raised unit 1. Then, the electric telescopic rod 8 is operated to control the movement and retraction of the support column 7 and the rectangular column 6, causing the rectangular column 6, the frame 2, and the unit 1 to move downwards. The unit 1 descends to the transport platform at the rear of the transport vehicle. The support column 7 is then moved and retracted until it is completely moved back to below the rectangular column 6. Next, the cylinder 52 is operated to control the pull rod 5 to rotate and approach the support steel frame 3, causing the rectangular column 6 and the support column 7 to move and fit against the side of the support steel frame 3, reducing the space occupied by the external structure of the entire diesel generator set. At this time, the unit 1 is loaded onto the transport vehicle. The transport vehicle can realize the movement and transportation of the unit 1. No additional hoisting or lifting equipment is needed during the loading and unloading process, making the operation convenient.

[0048] During the movement and unfolding of the support column 7 and the rectangular column 6, the reinforcing support rod 9 below the support column 7 is driven by the movement of the support column 7 and rotates and unfolds autonomously. The reinforcing support rod 9 is tilted and supported on the side of the support column 7. At the same time, the guide rod 12 and the telescopic guide rod 13 rotate and unfold under the rotational pulling force of the reinforcing support rod 9 below. Under the elastic thrust of the limiting spring 14, the guide rod 12 and the telescopic guide rod 13 are tilted and supported between the guide slide 62 and the positioning seat 10. (During the lifting and lowering adjustment of the support column 7, the guide slide 62 follows the support column 7 and slides directionally along the direction of the guide groove 61.) The unfolding of the reinforcing support rod 9 and the guide rod 12 can drive the positioning seat 10 and the universal wheel 11 to move and unfold, so that the universal wheel 11 is in close contact with the ground. This ensures that the four-way lifting drive structure is stable during the lifting and unloading process of the chassis 1. Furthermore, if the driving forces output by the four sides are not synchronized, causing the chassis 1 to tilt during lifting, and if the chassis 1 descends too quickly, resulting in instability on one side and impact with the contact surface, the limiting spring 14 between the telescopic guide rod 13 and the guide rod 12 can elastically adjust and buffer the vibration force during the descent, keeping the chassis 1 descending stably.

[0049] Example 2: Please refer to Figures 9-15 Based on Embodiment 1, a power mechanism and a self-locking mechanism are also disclosed, the specific structure of which is as follows: a power mechanism for driving the reinforcing support rod 9 to rotate is provided in the support rod 7, and a self-locking mechanism for limiting the rotation angle of the reinforcing support rod 9 is provided on the support rod 7.

[0050] Please see Figures 9-15 The power mechanism includes a side groove 91 opened on the support pole 7, the position of the side groove 91 is laterally corresponding to the position of the reinforcing support pole 9; a half gear 92 is sleeved and fixed on the reinforcing support pole 9 along its rotation axis, and the half gear 92 is inserted through the side groove 91; the reinforcing support pole 9 rotates downward to the maximum position, causing the universal wheel 11 to fit against the ground.

[0051] Please see Figures 9-15 A cylindrical rod 93 is fixedly connected inside the rectangular column 6 along the central axis, and the cylindrical rod 93 extends through into the interior of the supporting column 7; a lifting rod 94 is fixedly installed on the lower end face of the cylindrical rod 93, and racks 95 are fixedly installed on both sides of the lifting rod 94. The position of the racks 95 corresponds to the position of the side grooves 91, and the racks 95 are meshed with the half gears 92; the height of the upper end face of the lifting rod 94 is lower than the height of the lower end face of the rectangular column 6.

[0052] Please see Figure 9 and Figure 10 The self-locking mechanism includes a fixed frame 96 fixedly mounted on the support pole 7, and an elastic element 97 fixedly mounted on the fixed frame 96. The elastic element 97 is inclinedly connected to the fixed frame 96, and the end of the elastic element 97 near the reinforcing support pole 9 has an inclined angle structure. The reinforcing support pole 9 has a slot 98, through which the elastic element 97 passes and engages with the reinforcing support pole 9 for limiting connection, and the inclined angle above the elastic element 97 elastically fits against the surface of the reinforcing support pole 9.

[0053] During the process of controlling the lifting and unfolding of the support pole 7 and the rectangular column 6, the support pole 7 controls the rectangular column 6 to lift up or lower down. At this time, the cylindrical rod 93 fixed in the rectangular column 6 moves relative to the support pole 7. When the support pole 7 initially moves and unfolds, the lifting rod 94 and the rack 95 below the cylindrical rod 93 correspond to the side of the half gear 92. At this time, the rack 95 and the half gear 92 are meshed and connected. Under the meshing transmission, the half gear 92 can be driven to rotate outward. The half gear 92 drives the reinforcing support pole 9 to rotate outward synchronously, thereby achieving the purpose of controlling the reinforcing support pole 9 to move and unfold outward.

[0054] Continue to control the lifting and adjustment of the support rod 7 and the rectangular column 6. The cylindrical rod 93 drives the lifting rod 94 and the rack 95 to move and separate from the half gear 92, so that the subsequent extension and adjustment of the support rod 7 does not interfere with the rotation of the reinforcing rod 9. During the rotation and unfolding of the reinforcing rod 9, the slot 98 opened inside it contacts the elastic inclined surface on the side of the elastic element 97. The elastic inclined surface of the elastic element 97 is deformed by force, so that the entire elastic element 97 passes through the slot 98. When the inclined surfaces on both sides of the elastic element 97 pass through the slot 98, its end face is no longer subjected to the squeezing force. At this time, the elastic inclined surface of the elastic element 97 unfolds to the initial state on its own. The unfolding of the elastic inclined surface of the elastic element 97 is limited to the surface of the reinforcing rod 9, thereby limiting the position of the reinforcing rod 9 at this time. This allows the reinforcing rod 9, the guide rod 12, and the telescopic guide rod 13 to unfold and tilt to support the outside of the support rod 7, keeping the lifting and unloading of the chassis 1 relatively stable.

[0055] When transporting the generator set on a smooth road, the support poles 7 and rectangular columns 6 are folded and stored on the outside of the casing 1, as shown below. Figure 2As shown, when transporting the generator set on bumpy roads, the control support pole 7 and rectangular column 6 extend and support the outside of the chassis 1. At this time, the reinforcing support pole 9, guide rod 12, and telescopic guide rod 13 extend and support the outside of the support pole 7, and the casters 11 are in contact with the ground. Figure 1 As shown, during transportation, the reinforcing struts 9, guide rods 12, and telescopic guide rods 13 provide buffer support for the outside of the chassis 1, reducing the vibration force transmitted by road bumps, maintaining the relative stability of the chassis 1 on the transport vehicle, preventing damage to its internal electrical structure, and extending the service life of the generator set.
