Description

Technical Field

[0001] The invention relates to the technical field of diesel generator sets, in particular to a self-loading and unloading diesel generator set structure. Background Art

[0002] The diesel generator set structure is a backup power source with good comprehensive performance. It can be used for emergency power supply in many important occasions such as communication, rescue, medical treatment, and military. The overall structure of the diesel generator set is large, with many internal electrical components and a heavy unit structure. It is inconvenient to carry it directly by hand. When transporting the diesel generator set structure, hoisting equipment or lifting equipment is required to assist in loading and unloading the diesel generator set structure on the transport vehicle.

[0003] For example, the patent with publication number CN214650647U discloses a diesel generator set transfer device that is easy to load and unload, including a device base and a protective shell, the inner wall of the device base is provided with a slide groove, and a push-pull rod is passed through the inside of the slide groove, a first spring is installed on the outer side of the push-pull rod, and a storage groove is passed through one end of the push-pull rod, a second spring is installed inside the storage groove, and a connecting rod is provided inside the second spring, a slot is provided inside the connecting rod, and a universal wheel is installed below the connecting rod, a storage platform is provided above the device base, and a storage cavity is provided inside the storage platform, and a buffer spring is installed inside the storage cavity, a storage groove is connected above the buffer spring, and a power generation device is installed inside the storage groove, and the protective shell is installed on the storage platform; the diesel generator set transfer device that is easy to load and unload can be easily loaded and unloaded, and has a protective function.

[0004] For example, the patent with publication number CN210733935U discloses a diesel generator assembly and unloading device, which includes a carriage, a cab fixedly connected to either side of the carriage, two symmetrically arranged second hydraulic cylinders respectively provided on the top of the carriage near the cab and away from the cab, the second hydraulic cylinder on the top of the carriage away from the cab is provided with a first hydraulic cylinder away from the cab, universal wheels are provided at the bottom of the first and second hydraulic cylinders, a fixed frame is provided above the carriage, three sets of support frames are provided 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 away from the fixed frame, a chute is provided at the center of the top of the carriage, and the chute is perpendicular to the cab. This device can load and unload the generator set by itself, avoiding the use of a crane for transportation and saving costs. In addition, this product is simple and convenient to use, saves labor hours, improves loading and unloading efficiency, and is stable and safe.

[0005] For example, the patent with publication number CN218950407U discloses a diesel generator transport and loading and unloading device, which solves the current problem of inconvenience in quickly realizing the loading and unloading of diesel generator sets. The device comprises a base, the bottom of the base is fixedly installed with universal self-locking wheels near the four corners, and the top of the base is installed with a fixing mechanism for fixing the diesel generator set. The fixing mechanism comprises a placement plate located above the base; the utility model facilitates the rotation of the two movable plates to a vertical state through the cooperation between the movable plate and the movable rod as well as the spring and the top plate, and at the same time enables the top plate to move downward, and enables the two clamping plates to clamp and fix the diesel generator set, and at the same time the two movable plates can be rotated to a horizontal state, so that the positioning column is inserted into the interior of the positioning sleeve, and then It is easy to release the fixation of the diesel generator set, thereby facilitating the rapid loading and unloading of the diesel generator set; during the loading, unloading and lifting process of some existing diesel generator sets, due to inconsistent driving force output, it is easy to cause the overall imbalance of the generator set structure and tilt on one side. During the loading and unloading process, the tilt of the unit structure will cause instability during the equipment lifting process, and the unit structure will be unevenly stressed when in contact with the ground or the transport vehicle. When the unit structure falls to the ground, it is easy to impact and vibrate, causing damage to the internal power components and affecting the service life of the diesel generator set. In addition, when the generator set is transported on some bumpy roads, there is no structure in the transport vehicle to buffer the bumps to keep the generator set moving stably, resulting in bumps and vibrations during transportation of the generator set, which can easily damage its internal power structure.

[0006] In response to the above problems, it is urgent to carry out innovative design based on the original diesel generator set structure. Summary of the Invention

[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 beside the frame by running the cylinder, so that the rectangular column is supported on the four sides of the chassis and the frame, and the electric telescopic rod is run to push the supporting vertical pole to move and unfold under the rectangular column, so that the chassis and the frame move upward, so as to realize autonomous lifting and adjustment of the chassis and the frame, and the self-loading and unloading operation of the chassis can be completed without the use of additional hoisting or lifting equipment.

[0019] Furthermore, a support mechanism is provided between the support uprights and the rectangular columns to maintain the balance of the chassis lifting and loading and unloading. In the process of controlling the movement and expansion of the support uprights and the rectangular columns, the reinforced support rods are driven by force to rotate and expand on the sides of the support uprights. The guide rods and telescopic guide rods connected between the positioning seats and the guide slides are autonomously retracted and adjusted, and they autonomously rotate and expand, so that the reinforced support rods, guide rods and telescopic guide rods are rotated and tilted to support the sides of the support uprights and the rectangular columns. The reinforced support rods, guide rods and telescopic guide rods are provided with support structures in two directions of the support uprights and the rectangular columns, which can maintain the stability of the four-way driving force output during the lifting of the chassis, so that the chassis can be lifted and loaded and unloaded as stably as possible.

[0020] The guide rod and the telescopic guide rod are elastically connected with a limit spring. This part of the structure can adjust itself elastically during the chassis lifting and adjusting process, which plays a buffering role in the chassis lifting and lowering operation, avoiding the chassis lifting and lowering drive too fast and colliding with the ground or the transport vehicle, and ensuring that the chassis can land smoothly.

[0021] Furthermore, a power mechanism for driving the reinforcement support rod to rotate is provided in the support pole.

When the reinforcement support rod is rotated and expanded to the maximum angle, the rack and the half gear move and separate, and the reinforcement support rod is elastically engaged with the elastic part, so that the expansion angle of the reinforcement support rod is limited, and the reinforcement support rod is kept in the expanded state connected to the supporting pole.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts 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 solutions: a self-loading and unloading diesel generator set structure, including a chassis 1 for installing diesel generator components, a frame 2 fixedly installed on the outside of the chassis 1, and support steel frames 3 fixedly installed at the four corners of the frame 2; an upper pull rod 4 and a lower pull rod 5 are rotatably connected in sequence from top to bottom in the support steel frame 3, and the sides of the upper pull rod 4 and the lower pull rod 5 are rotatably connected with a rectangular column 6, and the upper pull rod 4 and the lower pull rod 5 are arranged with the same inclination between the support steel frame 3 and the rectangular column 6, and a support vertical rod 7 is provided in a sliding sleeve inside the rectangular column 6; a support mechanism for maintaining the balance of the chassis 1 in lifting and loading and unloading is provided between the support vertical rod 7 and the rectangular column 6, and the lifting and adjustment of the support vertical rod 7 controls the autonomous extension and folding and storage of the support mechanism.

[0042] See also Figure 2-Figure 6The lower pull rod 5 is fixedly connected to a protrusion 51 on the side, 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 lower pull rod 5 and the support steel frame 3.

[0043] See also 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 supporting upright rod 7; a guide slot 61 is provided on the rectangular column 6, and a guide slide 62 is slidably connected in the guide slot 61. The guide slide 62 is fixedly connected to the supporting upright rod 7, and the guide slide 62 is clamped on the outside of the rectangular column 6.

[0044] See also Figure 1-Figure 3 、 Figure 7-Figure 9 The support mechanism includes two groups of reinforcement rods 9 rotatably mounted on the outside of the support pole 7, and the two groups of reinforcement rods 9 are vertically distributed; the other end of the reinforcement rod 9 is rotatably mounted with a positioning seat 10, and the positioning seat 10 is rotatably mounted with a universal wheel 11.

[0045] See also Figure 1-Figure 3 、 Figure 7-11 The support mechanism also includes a guide rod 12 rotatably connected to the positioning seat 10, and the end of the guide rod 12 away from the positioning seat 10 is slidably connected with a telescopic guide rod 13, and the telescopic guide rod 13 is rotatably connected to the guide slide 62; a limiting spring 14 is elastically connected between the telescopic guide rod 13 and the guide rod 12.

[0046] When the control chassis 1 is autonomously lifted and loaded and unloaded, its lifting process is as follows: the cylinder 52 is operated to push the protrusion 51 away from the supporting steel frame 3. At this time, the lower pull rod 5 is connected between the supporting steel frame 3 and the rectangular column 6 and rotates, so that the rectangular column 6 moves outward and expands at the corners of the frame 2. During the outward movement of the rectangular column 6, the upper pull rod 4 also rotates and expands. The two sets of pull rods can keep the rectangular column 6 connected to the supporting steel frame 3 and stably expanded. Then the electric telescopic rod 8 is operated to push the supporting vertical pole 7 to lift and move. The expansion of the supporting vertical pole 7 can lift the frame 2 and the chassis 1 upward, thereby achieving the purpose of autonomous lifting of the control chassis 1.

[0047] When the chassis 1 is controlled to lift and unload autonomously, its lowering process is as follows: first, move the rear transport platform of the transport vehicle to the bottom of the raised chassis 1, operate the electric telescopic rod 8 to control the movement and contraction of the support uprights 7 and the rectangular columns 6, so that the rectangular columns 6, the frame 2 and the chassis 1 move downward, and the chassis 1 drops to the transport platform at the rear of the transport vehicle, and continue to control the movement and contraction of the support uprights 7 so that the support uprights 7 are completely moved and retracted to the bottom of the rectangular columns 6, and then operate the cylinder 52 to control the lower pull rod 5 to rotate close to the supporting steel frame 3, so that the rectangular columns 6 and the supporting uprights 7 move to fit the side positions of the supporting steel frame 3, reducing the space occupied by the external structure of the entire diesel generator set. At this time, the chassis 1 is loaded onto the transport vehicle, and the transport vehicle can realize the movement and transportation of the chassis 1. No additional lifting or lifting equipment is required during the loading and unloading process, and the operation is convenient.

[0048] In the process of controlling the movement and expansion of the support rod 7 and the rectangular column 6, the reinforcement rod 9 below the support rod 7 is driven by the movement of the support rod 7 and rotates and expands autonomously. The reinforcement rod 9 is tilted and supported on the side of the support rod 7. At the same time, the guide rod 12 and the telescopic guide rod 13 are rotated and expanded under the rotation tension of the reinforcement rod 9 below. The guide rod 12 and the telescopic guide rod 13 are tilted and supported between the guide slide 62 and the positioning seat 10 under the elastic thrust of the limit spring 14 (the guide slide 62 follows the support rod 7 in the process of lifting and lowering the support rod 7 and slides along the direction of the guide slot 61). ), the expansion of the reinforcement support rod 9 and the guide rod 12 can drive the positioning seat 10 and the universal wheel 11 to move and expand, so that the universal wheel 11 is closely supported on the ground, so that the chassis 1 is supported stably by the four-way lifting drive structure during the lifting and loading and unloading process. If the driving force output by the four directions is not synchronized, causing the chassis 1 to tilt when lifting, and the chassis 1 is too fast during the landing process, resulting in one side being unstable and colliding with the contact surface, the limit spring 14 between the telescopic guide rod 13 and the guide rod 12 is elastically adjusted to buffer the vibration force during the landing process and keep the chassis 1 landing stably.

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

[0050] See also Figures 9-15 The power mechanism includes a side groove 91 provided on the supporting rod 7, and the position of the side groove 91 corresponds laterally to the position of the reinforcing support rod 9; a half gear 92 is fixed on the reinforcing support rod 9 along its rotation axis, and the half gear 92 is arranged through the side groove 91; the reinforcing support rod 9 rotates downward to the maximum position to drive the universal wheel 11 to fit on the ground.

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

[0052] See also Figure 9 and Figure 10 The self-locking mechanism includes a mounting bracket 96 fixedly mounted on the support rod 7, on which an elastic member 97 is fixedly mounted. The elastic member 97 is connected obliquely to the mounting bracket 96, and the end of the elastic member 97 near the reinforcement rod 9 is in an oblique angled structure. The reinforcement rod 9 has a slot 98, through which the elastic member 97 passes to engage with the reinforcement rod 9, and the oblique angle above the elastic member 97 elastically fits the surface of the reinforcement rod 9.

[0053] In the process of controlling the lifting, movement and deployment of the support pole 7 and the rectangular column 6, the support pole 7 controls the rectangular column 6 to lift up or drop down. At this time, the cylindrical rod 93 fixed in the rectangular column 6 passes through the support pole 7 and moves relatively. When the support pole 7 initially moves and deploys, the lifting rod 94 and the rack 95 under the cylindrical rod 93 correspond to the sides of the half gear 92. At this time, the rack 95 is meshed with the half gear 92. Under the meshing transmission, it can drive the half gear 92 to rotate outward, and the half gear 92 drives the reinforcement rod 9 to rotate outward synchronously, thereby achieving the purpose of controlling the reinforcement rod 9 to move outward and deploy.

[0054] The cam 94 is then moved to the left of the support rod 7 and the cam 95 is moved to the right of the support rod 7. The cam 94 is then moved to the right of the support rod 7 and the cam 95 is moved to the right of the support rod 7.

[0055] When transporting the generator set on a smooth road, the support poles 7 and rectangular columns 6 are folded and stored outside the chassis 1. Figure 2In the state shown, when transporting the generator set on some bumpy roads, the control support pole 7 and the rectangular column 6 are unfolded and supported on the outside of the chassis 1. At this time, the reinforcement rod 9, the guide rod 12 and the telescopic guide rod 13 are unfolded and supported on the outside of the support pole 7, and the universal wheel 11 is attached to the ground. Figure 1 In the state shown, during the transportation process, the reinforced support rods 9, guide rods 12 and telescopic guide rods 13 provide buffering support for the outside of the chassis 1, reduce the vibration force transmitted by road bumps, maintain the relative stability of the chassis 1 on the transport vehicle, avoid damage to its internal power structure, and extend the service life of the generator set.
