Description

Technical Field

[0001] This utility model relates to the field of mobile device technology, and in particular to an auxiliary mobile device for a diesel generator set. Background Technology

[0002] A diesel generator set is a power generation device that uses a diesel engine as a power source to drive a generator, thereby converting mechanical energy into electrical energy. It features a wide power range, rapid start-up, ease of operation, and high reliability, and is widely used in various fields such as industry, agriculture, commerce, medical care, communications, and construction, playing a particularly important role in emergency power supply and power supply in remote areas. Due to the large size and heavy weight of diesel generator sets, auxiliary moving devices are required for transportation when installing, maintaining, or relocating them.

[0003] However, existing auxiliary moving devices for diesel generator sets generally suffer from insufficient stability. Due to the large mass of the diesel generator set itself, the vertical impact force from road bumps and the centrifugal force during turns can disrupt the original force balance of the device during movement. Many auxiliary moving devices have poor structural design, with a high center of gravity and limited support area. When the auxiliary moving device turns, the centrifugal force will cause the unit to generate a tilting moment towards the outside of the curve. Due to the imperfect center of gravity and support structure, the device cannot provide sufficient anti-overturning moment to balance it, resulting in increased shaking of the unit and even a rollover accident. This can not only cause loosening and damage to internal components, reducing the unit's performance and service life, but also pose safety hazards. Therefore, it is necessary to design an auxiliary moving device for diesel generator sets.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] This utility model provides an auxiliary moving device for diesel generator sets to solve the problem that existing auxiliary moving devices for diesel generator sets have poor stability and are prone to swaying and tipping over due to the weight of the generator set, road surface force, and poor device structure, which affects the performance of the generator set.

[0006] This utility model embodiment adopts the following technical solution: an auxiliary moving device for a diesel generator set. It includes a supporting base plate and a stabilizing assembly. A supporting platform is mounted on the supporting base plate. The stabilizing assembly includes a driving part disposed on the upper end of the supporting base plate. The driving part includes an extension rod disposed on the upper end of the supporting base plate and two sets of sliding seats that slide towards or away from each other along the length of the extension rod. A fixed cover is mounted on the supporting platform. A cylinder is installed inside the fixed cover. A support member is installed at the output end of the cylinder. The extension rod is installed at one end of the support member. A chain is sleeved on the sliding seat via a fixed shaft. The chain passes through the extension rod. A sliding groove for chain displacement is opened at the bottom of the extension rod. A hook is installed at one end of the chain. The two sets of hooks have a certain gap. Two sets of lifting rings are threadedly connected to the diesel generator set. The lifting rings are adapted to the hooks.

[0007] Furthermore, the extension rod is a hollow structure, and a double-acting screw is installed inside the extension rod with a bearing. The double-acting screw has two sections of threads with different directions of rotation. Two sets of guide rods are installed between the inner walls of the extension rod, and the two sets of guide rods are respectively located on both sides of the double-acting screw. Two sets of sliding seats are threadedly connected to the double-acting screw, and the two sets of sliding seats are respectively located at the two sections of threads with different directions of rotation. One end of the double-acting screw passes through one end of the extension rod, and a turntable is installed at one end of the double-acting screw.

[0008] Furthermore, a clamping unit is installed on the support base plate. The clamping unit includes four sets of limiting plates disposed on the support base plate. Angle plates are installed on the sides of the limiting plates. The angle plates are installed on the support base plate by bolts. The four sets of limiting plates are spliced ​​together to form a square structure. The square structure is suitable for conforming to the four side contours of the diesel generator set.

[0009] Furthermore, a limiting component is installed on the support platform. The limiting component includes two sets of support rods installed on the support platform. A fixing sleeve is installed on the support rod. A rotating shaft is mounted between the two sets of fixing sleeves. A clamping rod is installed on each of the two sets of rotating shafts. Two sets of pressing rods are connected between the two sets of clamping rods. There is a certain gap between the two sets of pressing rods. The pressing rods are L-shaped and are adapted to fit against the two right-angled sides of the upper end of the diesel generator set. A driving component is provided on one side of one set of fixing sleeves. The output end of the driving component is connected to the rotating shaft.

[0010] Furthermore, there is a certain gap between the two sets of clamping rods, and there is a certain gap between one end of the extension rod and one set of the pressing rods.

[0011] Furthermore, the pressure rod is fixedly connected to the clamping rod by fasteners to form a detachable assembly structure.

[0014] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0015] An auxiliary moving device for a diesel generator set is disclosed. An extension rod driven by a cylinder moves along the generator set direction, aligning the hook with the lifting ring. Adjusting the lifting point effectively lowers the overall center of gravity. Two sets of sliding seats slide synchronously in opposite directions along the extension rod, allowing the hook spacing to be adjusted according to the generator set width, forming an adaptive wide-width support structure. When the device turns or encounters bumps, the sliding seats change the chain tension distribution, creating a balancing torque opposite to centrifugal force or impact force, suppressing generator set sway. The chain connection design buffers vertical vibration, reducing the risk of internal parts loosening. Attached Figure Description

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0027] Reference Figures 1 to 5 As shown, this utility model embodiment provides an auxiliary moving device for a diesel generator set, including a moving component 1, a stabilizing component 2, and a limiting component 3. The moving component 1 includes a support base plate 11 for placing the diesel generator set 16. A support platform 15 is fixedly installed on the support base plate 11, and four sets of sliding wheels 12 for moving the moving component 1 are fixedly installed at the bottom of the support base plate 11.

[0028] The stabilizing assembly 2 includes a drive unit disposed on the upper end of the support base plate 11. The drive unit includes an extension rod 24 disposed on the upper end of the support base plate 11. The extension rod 24 is a hollow structure, and a bidirectional lead screw 25 is mounted on a bearing inside the extension rod 24. The bidirectional lead screw 25 has two threads with different directions of rotation. At the same time, two sets of guide rods 26 are fixedly installed between the inner walls of the extension rod 24. The two sets of guide rods 26 are respectively located on both sides of the bidirectional lead screw 25.

[0029] Furthermore, two sets of sliding seats 27 are threadedly connected to the bidirectional lead screw 25. The two sets of sliding seats 27 are located at two different threads with different directions of rotation. The sliding seats 27 are simultaneously movably sleeved on two sets of guide rods 26. The two sets of guide rods 26 are suitable for axially restricting the movement of the sliding seats 27.

[0030] Furthermore, one end of the bidirectional lead screw 25 passes through one end of the extension rod 24, and a turntable 210 is fixedly installed at one end of the bidirectional lead screw 25. The turntable 210 is suitable for driving the bidirectional lead screw 25 to rotate.

[0031] The operator can drive the bidirectional lead screw 25 to rotate by rotating the turntable 210. Since the two sections of the bidirectional lead screw 25 have opposite threads, the two sets of sliding seats 27, which are respectively threaded to it, will move synchronously and in opposite directions along the bidirectional lead screw 25 under the axial constraint of the guide rod 26 (that is, when the turntable 210 rotates clockwise, the two sliding seats 27 move towards the middle; when it rotates counterclockwise, they separate to the sides).

[0032] A fixed cover 21 is fixedly installed on the support platform 15. A cylinder 22 is fixedly installed inside the fixed cover 21, and a support member 23 is fixedly installed at the output end of the cylinder 22. An extension rod 24 is fixedly installed at one end of the support member 23. The extension rod 24 is adapted to move closer to or further away from the diesel generator set 16 placed on the support base plate 11 as the cylinder 22 extends or retracts.

[0033] Furthermore, a chain 28 is sleeved on the sliding seat 27 via a fixed shaft 211. The chain 28 passes through the extension rod 24, and a sliding groove (not shown in the figure) is provided at the bottom of the extension rod 24 for the chain 28 to move. The width of the sliding groove is greater than the size of the chain 28, and a hook 29 is fixedly installed at one end of the chain 28. The two sets of hooks 29 have a certain gap, which is suitable for providing balanced support for the diesel generator set 16. At the same time, two sets of lifting rings 161 are threadedly connected to the diesel generator set 16. The lifting rings 161 are suitable for use with the hooks 29 to keep the diesel generator set 16 suspended and prevent shaking.

[0034] It should be noted that when the diesel generator set 16 is placed on the support base plate 11, the cylinder 22 inside the fixed cover 21 starts first. Its output end pushes the extension rod 24 closer to the generator set through the support member 23, so that the hook 29 at one end of the chain 28 first approaches the lifting ring 161. Thus, the position of the extension rod 24 can be adjusted according to the size of the generator set to ensure that the connection point of the two sets of hooks 29 and the lifting ring 161 of the generator set is as close as possible to the vertical line of the generator set's center of gravity, thereby reducing the overall center of gravity height.

[0035] Subsequently, the operator drives the double-ended lead screw 25 to rotate via the rotary turntable 210. Utilizing its two-section reverse thread characteristic, the two sets of sliding seats 27 move synchronously in opposite directions along the guide rod 26 to the designated position (e.g., adjusting the lateral spacing of the hooks 29 according to the width of the unit). At this point, the lifting ring 161 is connected to the hook 29, and then the cylinder 22 inside the fixed cover 21 is activated, allowing the hook 29 at one end of the chain 28 to support the diesel generator set 16 through the lifting ring 161, thus maintaining the tension of the chain 28. The rigid support spacing established by the double-ended lead screw 25 is kept constant through mechanical transmission, ensuring that the unit is always subjected to balanced lateral constraint during movement, suppressing lateral swaying caused by centrifugal force or crosswinds, and avoiding the defect of "single lifting point cannot constrain lateral displacement" in traditional fixed hoisting methods.

[0036] Reference Figure 2 As shown, specifically, a clamping unit is installed on the supporting base plate 11. This clamping unit includes four sets of limiting plates 13 disposed on the supporting base plate 11. Angle plates 131 are fixedly installed on the sides of the limiting plates 13, and these angle plates 131 are bolted to the supporting base plate 11. The four sets of limiting plates 13 are spliced ​​to form a square structure, which is suitable for conforming to the four side contours of the diesel generator set 16, physically limiting the unit from the bottom. When the auxiliary moving device is activated or encounters road bumps or centrifugal force during movement, the friction and lateral support force generated by the tight contact between the limiting plates 13 and the bottom of the unit can effectively prevent lateral displacement and tilting tendency of the unit, thereby achieving stable constraint on the bottom of the diesel generator set 16.

[0037] Reference Figures 1-4 As shown, specifically, the limiting component 3 includes two sets of support rods 31 fixedly installed on the support platform 15. A fixing sleeve 32 is fixedly installed on the support rod 31, and a rotating shaft 37 is mounted between the two sets of fixing sleeves 32. At the same time, a clamping rod 33 is fixedly installed on each of the two sets of rotating shafts 37. Two sets of pressing rods 34 are connected and installed between the two sets of clamping rods 33. There is a certain gap between the two sets of pressing rods 34, and the pressing rods 34 are L-shaped. The two sets of pressing rods 34 are adapted to fit against the two right-angled sides of the upper end of the diesel generator set 16 to limit the diesel generator set 16 in the vertical direction. A driving member 36 is provided on one side of each set of fixing sleeves 32. The output end of the driving member 36 is connected to the rotating shaft 37.

[0038] It should be noted that there is a certain gap between the two sets of clamping rods 33, and there is a certain gap between one end of the extension rod 24 and a set of pressing rods 34;

[0039] In the initial state, the drive unit 36 ​​tilts the two sets of clamping rods 33, providing space for the placement of the diesel generator set 16. Once the generator set is placed on the support base plate 11, the drive unit 36 ​​is activated, and its output end drives the rotating shaft 37 to rotate. Since the rotating shaft 37 is fixedly connected to the clamping rods 33, it drives the two sets of clamping rods 33 to rotate synchronously. The clamping rods 33 drive the L-shaped holding rods 34 to rotate until the holding rods 34 are in contact with the two right-angled edges of the upper end of the diesel generator set 16. The gap design between the two sets of holding rods 34 allows them to precisely fit the right-angled edge contour of the generator set, applying pressure from the vertical direction to fix the generator set on the support base plate 11.

[0040] Controlled by the drive unit 36, the position of the holding rod 34 can be flexibly adjusted according to the unit size, improving the versatility of the device. On the other hand, the vertical restriction of the upper part of the unit by the holding rod 34, together with the lateral restriction of the bottom of the unit by the clamping unit, forms a constraint, effectively suppressing the vertical jumping and displacement of the unit. When the auxiliary moving device encounters road bumps or centrifugal force during turning, the limiting component 3 and the bottom clamping unit work together to form a stable clamping force from both ends, enhancing the overall stability of the unit, reducing the risk of loosening and damage to internal parts due to shaking, and also preventing safety accidents such as rollover of the unit during movement, thus improving the safety and reliability of the auxiliary moving device.

[0041] Specifically, the clamping rod 34 is fixedly connected to the clamping rod 33 by fasteners (such as bolts, nuts, or quick-release clips), forming a detachable assembly structure. When dealing with diesel generator sets 16 of different lengths and widths, operators can replace the clamping rod 34 with different lengths, angles, or shapes by disassembling the fasteners. For example, for narrow generator sets, clamping rods 34 with smaller spacing can be used; for tall generator sets, extended L-shaped clamping rods 34 can be used to ensure that they always fit against the right-angled edge of the upper end of the generator set. This, combined with the angle adjustment of the clamping rod 33 by the drive component 36, allows for omnidirectional vertical positioning of various generator set specifications.

[0042] Specifically, an assist push rod 14 is fixedly installed on the support base plate 11. The assist push rod 14 provides a force application point for the operator. By manually pushing the assist push rod 14, the support base plate 11 and the diesel generator set 16 installed on it can be moved as a whole. A base 35 is fixedly installed on the side of the assist push rod 14. The drive component 36 is fixedly installed on the base 35, providing a stable installation foundation for the drive component 36.

[0043] Specifically, protective pads are provided at the contact points between the holding rod 34 and the limiting plate 13 and the diesel generator set 16. These protective pads are made of flexible silicone material. Utilizing the elastic deformation and buffering properties of silicone, rigid contact is transformed into flexible contact when the device clamps and limits the generator set. When the auxiliary moving device encounters road bumps or centrifugal force during turning, the protective pads can absorb and disperse the local stress generated by the clamping force and impact force, preventing the holding rod 34 and the limiting plate 13 from directly squeezing and rubbing against the generator set casing, thus preventing physical damage such as scratches and dents. At the same time, the silicone can provide stable friction without damaging the surface of the generator set, ensuring the reliability of clamping and limiting.

[0044] In summary: The stabilizing assembly 2 adjusts the position of the hook 29 by driving the extension rod 24 through the cylinder 22, so that the lifting point is close to the vertical line of the unit's center of gravity. Combined with the adjustment of the lateral spacing by the double-acting screw 25, a stable structure with a low center of gravity and wide support is formed. When the unit is placed, the cylinder 22 pushes the hook 29 closer to the lifting ring 161, shortening the slack length of the chain 28, and the preload offsets part of the vertical impact. When turning, the screw adjustment increases the tension of the outer chain 28, forming an anti-overturning moment.

[0045] The four sets of limiting plates 13 of the bottom clamping unit constrain the lateral displacement of the unit through friction and lateral support force, while the L-shaped pressure rod 34 at the top rotates and fits against the right-angled edge of the upper end of the unit through the drive component 36, forming vertical pressure. The combination of upper and lower clamping suppresses the tendency to bounce and roll over, and provides a continuous and stable restraint force, especially when the road surface is bumpy.

[0046] The detachable design of the clamping rod 34 allows for quick replacement of components of different specifications. Combined with the angle adjustment of the clamping rod 33 via the drive component 36, it achieves precise adaptation to units of various sizes. The silicone protective pad transforms rigid force into elastic cushioning at the contact interface, protecting the unit surface and enhancing limit reliability through its high coefficient of friction.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
