[0026] Figures 1-2 An implementation form of a retractable support foot pad is shown, which comprises two support plates 401 and a linkage structure;

[0027] The back of the two support plates 401 is provided with a mounting plate 402, the two ends of the mounting plate 402 are respectively provided with a first mounting hole 408 and a second mounting hole, the two support plates 401 comprise a left side support plate 401 and a right side support plate 401, the mounting plate 402 on the left side support plate 401 is arranged staggered with the mounting plate 402 on the right side support plate 401, and a first connecting shaft 404 penetrates the first mounting holes 408 on the two support plates 401, so that the two support plates 401 can be rotatably connected;

[0028] The linkage structure comprises one or more groups of linkage rods, a second connecting shaft 405 and a third connecting shaft 406, each group of linkage rods comprises two linkage rods 403, the two ends of each linkage rod 403 are respectively provided with a third mounting hole 409 and a fourth mounting hole 410, the second connecting shaft 405 penetrates the second mounting hole of the mounting plate 402 and the third mounting hole 409 of the linkage rod 403, so that the linkage rod 403 can rotate relative to the mounting plate 402, and the third connecting shaft 406 penetrates the fourth mounting hole 410 on each group of linkage rods, so that each group of linkage rods is hingedly connected in a herringbone shape, and the third connecting shaft 406 provides a lower end connection for the foot 412.

[0029] The retractable support foot pad of the utility model can be retracted by gravity, the two support plates 401 have a large contact surface with the ground when being unfolded, which is beneficial to ensure the stability of the equipment support, and the space occupied by the two support plates 401 when being retracted is small, which does not affect the installation and use of other functions of the equipment.

[0030] The utility model can retractable support foot pad through two mounting plates 402 on two support plates 401 and two linkage rods 403 of each group linkage rod form quadrilateral, and two second connecting shafts 405, a second connecting shaft 405 and a third connecting shaft 406 are combined to hingedly form four hinge points of four vertices of quadrilateral, make two mounting plates 402 on two support plates 401 and two linkage rods 403 of each group linkage rod overlap and form four bar structure, when the support foot 412 lifts the support foot pad through the third connecting shaft 406, under the action of gravity, the support foot pad is automatically retracted, when the support foot 412 pushes the support foot pad and presses the ground through the third connecting shaft 406, the first connecting shaft 404 of the two support plates 401 of the support foot pad is pushed by the ground, and under the action of the weight of equipment or machine, the two support plates 401 of the support foot pad are unfolded, so that a larger contact area is formed with the support plane (ground), to ensure the stability of the machine.

[0031] The support foot pad mainly has two states in the working process, that is, when not working, the support foot pad is automatically retracted under the action of gravity, so that the volume of the support foot pad is reduced, the use of other functions of the machine is avoided (the support foot pad is not used) Figure 2 ), and it is convenient to store; when working, the support foot pad contacts with the support plane (ground), and the two support plates 401 of the support foot pad are unfolded under the action of the weight of the machine, so that a larger contact area is formed with the support plane (ground), to ensure the stability of the machine (the support foot pad is used) Figure 1 ).

[0032] The mounting plates 402 on the two support plates 401 are staggered, that is, the two support plates 401 are designed asymmetrically, so that the two support plates 401 can be hingedly connected through the mounting plates 402, when the two support plates 401 are rotated downward to the horizontal state, the end portions of the two support plates 401 abut, the self-locking of the two support plates 401 is realized, the support plates 401 are prevented from continuing to rotate upward after being unfolded horizontally, a larger contact area is ensured, and the stability is improved.

[0033] When using:

[0034] When the equipment needs to improve the support stability and is often moved, a support foot pad can be installed on each support foot 412 of the required equipment, that is, the lower end of each support foot 412 is connected with the third connecting shaft 406 of the support foot pad. During the daily movement of the equipment, the support foot pad is always in the retracted state due to the retractable characteristics of the support foot pad. At this time, the two support plates 401 of the support foot pad are closely close, the linkage structure is compactly folded, the overall volume is small, and the movement of the equipment is not hindered.

[0035] When the device reaches the work site and needs stable support, place the device in the work area. As the device's own gravity acts on the foot 412, the foot 412 transmits the gravity to the support foot pad through the connection with the third connecting shaft 406. The two support plates 401 of the support foot pad begin to expand under the combined action of gravity and ground reaction force. Due to the asymmetric staggered design of the back mounting plate 402 of the two support plates 401, when the support plates 401 rotate downward to the horizontal state, their ends abut each other, realizing self-locking function. At this time, the support foot pad forms a large contact area with the ground, providing strong support stability for the device, effectively ensuring the smooth operation of the device during work. Even if the device produces some vibration or is slightly disturbed by the outside world during operation, it can remain stable and will not sway or fall.

[0036] When the device completes the work task and needs to be moved again, the operator only needs to lift the device to make the support foot pad leave the ground. Once the support force of the ground is lost, the two support plates 401 of the support foot pad quickly and automatically shrink together under the action of gravity, and the linkage structure is also reset and shrunk. The support foot pad quickly recovers to a small and compact state, and at this time the device can be easily moved to the next work site. In the process of frequently moving the device, this support foot pad can quickly and conveniently switch between the collapsed and expanded states, not only meeting the high requirements of the device for support stability during work, but also not causing inconvenience to the frequent movement of the device, greatly improving the use efficiency and flexibility of the device. Moreover, since each foot 412 is equipped with an independent support foot pad, the device can maintain good support balance in different terrains and working environments, further enhancing the adaptability and reliability of the device.

[0037] In use:

[0038] For devices equipped with telescopic storage feet 412, the use of the collapsible support foot pad exhibits unique adaptability and convenience.

[0039] When the device is ready to be stored, first control the telescopic storage feet 412 of the device to perform the shrinking action. At this time, the collapsible support foot pad connected to the lower end of the foot 412 responds synchronously. Since the foot 412 is shrunk upward, the support foot pad loses the support force of the ground and the two support plates 401 quickly and automatically shrink together under the action of their own gravity, and the linkage structure is also compactly folded. The entire support foot pad quickly recovers to a small and compact state, perfectly adapting to the shrinking process of the telescopic storage feet 412 of the device and not causing any obstruction to it, greatly facilitating the overall storage operation of the device, enabling the device to quickly and neatly complete the storage, reducing the occupied space, and facilitating storage or transportation.

[0040] When the device needs to be converted from the storage state to the moving state, the retracted support foot pad still maintains a small size and does not interfere with the movement of the device. Whether the device is manually pushed for short-distance movement indoors or is transferred by a carrying tool for long-distance transfer, the device can be easily moved by virtue of the flexibility of the telescopic storage support foot 412 and the compact design of the retractable support foot pad, thereby greatly improving the convenience of transferring the device between different sites.

[0041] After arriving at the work site, the telescopic storage support foot 412 of the operating device is extended. As the support foot 412 extends downward, the retractable support foot pad gradually approaches the ground. When the support foot pad contacts the ground, the device gravity is transmitted to the support foot pad through the support foot 412. The two support plates 401 of the support foot pad begin to expand under the combined action of gravity and ground reaction force. Due to the asymmetric staggered design of the back mounting plate 402 of the two support plates 401, when the support plates 401 are rotated downward to the horizontal state, the ends thereof abut each other to realize the self-locking function. At this time, the support foot pad forms a large contact area with the ground, providing stable and reliable support for the device to ensure smooth operation of the device during operation. Even if the device is shaken or slightly disturbed by the outside world, it can remain stable, effectively meeting the high requirements of the device on support stability during operation.

[0042] During the entire use cycle of the device, the combination of the device with telescopic storage support foot 412 and the retractable support foot pad can efficiently switch between the storage, moving, and working support states, fully utilizing the advantages of both and showing excellent application prospects. It not only meets the requirements of the device for convenient storage and small space occupation in the non-working state, but also provides strong support stability guarantee during work.

[0043] On the basis of the above implementation mode, the mounting plate 402 at the back of each support plate 401 includes two or more mounting plates 402, and the two or more mounting plates 402 are parallel to each other, thereby improving stability.

[0044] On the basis of the above implementation mode, a guide plate 407 is further included, a long strip-shaped guide slot 411 is arranged along the length direction of the guide plate 407, the bottom of the guide plate 407 is fixedly connected with the first connecting shaft 404, the third connecting shaft 406 is slidably sleeved in the long strip-shaped guide slot 411, the first connecting shaft 404 is parallel to the third connecting shaft 406, and the long strip-shaped guide slot 411 is arranged in parallel with the support foot 412.

[0045] When the support foot pad is expanded or retracted under the action of gravity, the support plate 401 may be inclined to one side. The guide plate 407 can ensure that the support plate 401 does not deviate to one side.

[0046] On the basis of the above implementation, the lower end of the supporting leg 412 is connected to the middle part of the third connecting shaft 406, improving stability.

[0047] On the basis of the above implementation, the supporting leg 412 is a telescopic supporting leg 412 that can be telescoped up and down, facilitating the contraction of the supporting leg pad for use.

[0048] Figure 3 An implementation form of a supporting leg equipped with a telescopic supporting leg pad is shown, including a supporting leg 412 and the above-mentioned telescopic supporting leg pad, the third connecting shaft 406 of the supporting leg pad is connected to the lower end of the supporting leg 412, and the upper end of the supporting leg 412 is connected to the required equipment.

[0049] On the basis of the above implementation, the supporting leg 412 is telescopically arranged in the circumferential direction of the mobile-offload power generation equipment.

[0050] The mobile-offload power generation equipment includes mobile-offload power generation equipment, and substations, transformer equipment and the like used in conjunction, by installing a telescopic supporting leg pad at the lower end of the telescopic supporting leg 412 in the circumferential direction of the equipment, both the need for convenience and small space occupation of the equipment in the non-working state are met, and strong support stability is provided when working.

[0051] The use process of the supporting leg for mobile-offload power generation equipment:

[0052] The mobile-offload power generation equipment (such as mobile-offload power generation equipment, substations, transformer equipment, etc.) is in a stationary state, and is provided with supporting legs equipped with telescopic supporting leg pads in the circumferential direction. These supporting legs are in an initial shortened state, and the supporting leg pads are also contracted to a small and compact form due to their own gravity, without occupying too much space.

[0053] When the equipment needs to be transported, the operator operates the supporting leg to perform an elongation action. As the supporting leg is elongated, the supporting leg pad contacts the ground and expands under the combined action of the equipment gravity and the ground reaction force. Due to the asymmetric staggered design of the supporting plate 401 and the back plate 402, the supporting plate 401 rotates downward to the horizontal state, and the rear ends of the supporting plate 401 abut each other to achieve self-locking, and the supporting leg pad forms a large contact area with the ground to provide stable support for the equipment. The supporting leg continues to elongate, gradually lifting the entire equipment, until enough space is left between the bottom surface of the equipment and the ground, which can allow a forklift or a carrier to smoothly extend into the bottom surface of the equipment.

[0054] After the forklift or the carrier truck accurately extends the carrying part thereof into the bottom surface of the equipment, the operator controls the support feet to perform a shortening action. During the shortening of the support feet, the weight of the equipment is gradually transferred to the forklift or the carrier truck, the support foot pads gradually lose the gravity from the equipment, and under the influence of the self-gravity, the two support plates 401 are quickly and automatically retracted to be close to each other, the linkage structure is also compactly folded, and the small and exquisite state is restored. With the continuous shortening of the support feet, the equipment is finally supported by the forklift or the carrier truck, at which time the support feet can be further shortened to a suitable position to avoid interference during transportation.

[0055] The forklift or the carrier truck carries the set-unset type power generation equipment and transports it to the required working position. During the entire transportation process, since the support foot pads are in the retracted state and are small in size, they will not hinder the movement of the equipment, and the transportation process is ensured to be smooth.

[0056] When the equipment reaches the specified position, the support feet are again operated to perform an elongation action. The elongation of the support feet causes the support foot pads to be in contact with the ground again, and under the combined action of the gravity of the equipment and the ground reaction force, the support plates 401 of the support foot pads are unfolded and self-locked to form a stable large contact area support with the ground. With the continuous elongation of the support feet, the equipment is gradually lifted, and the weight thereof is transferred from the forklift or the carrier truck to the support feet until the forklift or the carrier truck can easily exit from the bottom surface of the equipment and complete the separation from the equipment.

[0057] After the forklift or the carrier truck leaves, the operator controls the support feet to perform a shortening action. During the shortening of the support feet, the equipment slowly descends and finally sits on the required position. At this time, the support foot pads still remain in the unfolded state to provide stable and reliable support for the equipment, and the equipment can be stably operated during the subsequent working process. Even if the equipment is shaken or slightly disturbed by the outside world, the stability can be maintained. Alternatively, the support feet are directly retracted to the initial shortened state for standby, the bottom surface of the equipment serves as an equipment support surface, and the support feet are used as required to provide stable support for the entire loading and unloading process.

[0058] When the utility model is applied to the set-unset type power generation equipment, the support plates 401 can be made of high-quality steel plates, specifically Q345B steel plates produced by Anshan Iron and Steel, with a thickness of 12 mm and a size of 300 mm*200 mm. Such steel plates have high strength and toughness and can withstand the weight of the set-unset type power generation equipment and the ground reaction force.

[0059] The back mounting plate 402 of the support plate 401 can be fixed by welding, and the mounting plate 402 has a size of 200 mm x 50 mm x 10 mm and is also made of Q345B steel. The first mounting hole 408 and the second mounting hole at the two ends of the mounting plate 402 have a diameter of 20 mm, and the machining accuracy of the holes is controlled within ±0.1 mm to ensure the accuracy of subsequent connection. The mounting plate 402 on the left support plate 401 is arranged in a staggered manner with the mounting plate 402 on the right support plate 401, and the staggered distance is 10 mm, that is, the thickness of the mounting plate 402. This design facilitates the lapping of the left mounting plate 402 and the right mounting plate 402, and ensures that a stable motion trajectory and reliable support function can be achieved during the unfolding and folding of the support plate 401.

[0060] The linkage rod 403 is forged from 45 steel. The third mounting hole 409 and the fourth mounting hole 410 at the two ends of the linkage rod 403 have a diameter of 20 mm, and the machining accuracy is controlled within ±0.1 mm. The design and machining of the linkage rod 403 are required to ensure that it has sufficient strength and rigidity to transmit force and torque during the unfolding and folding of the support foot pad without bending or deforming.

[0061] The first connecting shaft 404, the second connecting shaft 405 and the third connecting shaft 406 are all made of 40Cr alloy steel material, and have a diameter of 20 mm and a length determined according to the installation position. These connecting shafts have high machining accuracy requirements to ensure the fitting accuracy during installation, so that the connection between the parts is tight and the rotation is smooth.

[0062] Although the embodiments of the utility model have been disclosed as above, they are not limited to the applications listed in the specification and embodiments. They can be fully applied to various fields suitable for the utility model. For those skilled in the art, other modifications can be easily realized.
