[0047] With reference to Figures 1-5 For the first embodiment of the utility model, a generator pull-out maintenance device in a shelter is provided for maintaining the generator, comprising a body 1, the body 1 has an inner cavity 101, and the generator is located in the inner cavity 101;A first sliding frame 2 is arranged at the bottom of the body 1;A second sliding frame 3 is horizontally slidably arranged on the first sliding frame 2, and the second sliding frame 3 is used for supporting the generator, and the second sliding frame 3 is configured to enter or exit the inner cavity 101 after sliding.

[0048] In this embodiment, a generator pull-out maintenance device in a military shelter is arranged in the military shelter. The body 1 of the device has an inner cavity 101, and the generator is installed in the inner cavity 101. The first sliding frame 2 is arranged at the bottom of the body 1, and the second sliding frame 3 for supporting the generator is horizontally slidably arranged on the first sliding frame 2. When the generator needs to be maintained, the second sliding frame 3 is pulled out of the inner cavity 101. Since the second sliding frame 3 horizontally slides on the first sliding frame 2, the operation is relatively smooth and labor-saving. During the pulling-out process, the generator moves together with the second sliding frame 3 until it completely exits the inner cavity 101, providing sufficient operating space for the maintenance personnel. After the maintenance work is completed, the second sliding frame 3 is pushed back into the inner cavity 101, so that the generator returns to the initial position. Through the sliding design of the second sliding frame 3, the generator can be easily pulled out of the inner cavity 101 for maintenance, greatly improving the convenience of maintenance and reducing the difficulty and time cost of maintenance. When maintenance is not required, the generator is located in the inner cavity 101, which reasonably utilizes the space in the shelter and does not affect the layout and use of other equipment in the shelter. The cooperation of the first sliding frame 2 and the second sliding frame 3 provides stable support and guidance for the movement of the generator, ensuring the safety and stability of the generator during movement. The generator is built-in in the inner cavity 101 of the body 1, effectively avoiding the direct influence of wind, rain and other harsh environments on the generator, reducing the failure rate and improving the working reliability of the generator in harsh conditions such as field environment.

[0049] Further, the first sliding frame 2 has side rail portions 201 on both sides, and the second sliding frame 3 has sliding clamping edges 301 on both sides, which are slidably arranged on the side rail portions 201.

[0050] In this embodiment, when the generator is pulled out or pushed back, the sliding clamping edge 301 of the second sliding frame 3 smoothly slides along the side rail part 201 of the first sliding frame 2. This structural design ensures the accuracy and stability of the sliding. During the pulling-out process, the sliding clamping edge 301 tightly fits with the side rail part 201, preventing the second sliding frame 3 from shaking or deviating from the track during movement. When pushed back, it can also ensure accurate resetting, so that the generator accurately returns to the designated position in the inner cavity 101. The cooperation of the side rail part 201 and the sliding clamping edge 301 provides accurate guidance for the sliding of the second sliding frame 3, ensuring the accuracy of the movement path of the generator and facilitating maintenance operations. This structure effectively prevents the second sliding frame 3 from shaking and deviating during sliding, enhances the stability of the entire pulling process, and protects the generator from additional vibration and collision. Precise sliding fit reduces unnecessary friction and wear between components, prolongs the service life of the sliding frame, and reduces maintenance costs. Stable and accurate sliding structure reduces the risk of damage to the generator or injury to personnel due to improper pulling, improving the safety of the operation.

[0051] Further, the side rail part 201 has a first fixing hole 202, the sliding clamping edge 301 has a second fixing hole 203, and the lifting clamping piece 4 is arranged to slide up and down in the second fixing hole 203 and penetrate the first fixing hole 202. The lifting clamping piece 4 is configured to be clamped into or out of the first fixing hole 202 after sliding up and down.

[0052] In this embodiment, when the second sliding frame 3 slides to a specific position and needs to be fixed, the lifting clamping piece 4 slides up and down in the second fixing hole 203. When it is lowered, the lifting clamping piece 4 penetrates the first fixing hole 202, thereby clamping into the first fixing hole 202, achieving the fixation of the second sliding frame 3. When the second sliding frame 3 needs to be slid again, the lifting clamping piece 4 is lifted to leave the first fixing hole 202, thereby releasing the fixation and enabling the sliding operation. The cooperation of the lifting clamping piece 4 with the first fixing hole 202 and the second fixing hole 203 can firmly lock the position of the second sliding frame 3, avoiding the sliding of the second sliding frame 3 due to external force during maintenance, and ensuring the safety and stability of the maintenance work. The lifting operation of the lifting clamping piece 4 is simple and can quickly achieve the fixation and unlocking of the second sliding frame 3, improving the work efficiency. Preventing accidental sliding of the second sliding frame 3 reduces the safety hazards caused by sliding and protects the personal safety of maintenance personnel.

[0053] Further, a middle beam 5 is arranged on both ends of the two sliding clamping edges 301, and the middle beam 5 is arranged in the length direction of the first sliding frame 2.

[0054] In actual application, when the second slide 3 slides on the first slide 2, the middle beam 5 can provide additional support and stability. The uniform distribution of multiple middle beams 5 makes the entire sliding structure more stable. During the process of pulling out the second slide 3, the middle beam 5 can share the weight of the generator, reduce the local pressure of the first slide 2 and the second slide 3, and prevent deformation. The arrangement of the middle beam 5 significantly enhances the overall structural strength of the first slide 2, enabling it to withstand greater weight and pressure, ensuring that it does not deform during long-term use. The arrangement of multiple middle beams 5 along the length direction enables the weight of the generator to be evenly distributed, avoiding damage caused by excessive local stress. It provides more stable support for the entire pull-out maintenance device, reduces shaking and instability during sliding, and ensures the safety of the generator. By sharing the load and enhancing the structure, the service life of the first slide 2 and the second slide 3 is effectively prolonged, reducing the frequency of maintenance and replacement.

[0055] Further, the leg 6 is arranged at one end of the middle beam 5, and the foot 7 is arranged on the leg 6 in a lifting and sliding manner.

[0056] In this embodiment, the leg 6 and the foot 7 are also provided. The leg 6 is arranged in a detachable manner. When not in use, the leg 6 can be placed in the inner cavity 101 of the machine body 1 to save space. When needed, the leg 6 is taken out from the inner cavity 101 and installed on the middle beam 5. One end of the leg 6 is fixed on the middle beam 5, and the foot 7 is arranged on the leg 6 in a lifting and sliding manner. When the second slide 3 is pulled out and the generator needs to be maintained, the foot 7 slides down along the leg 6 until it contacts the ground, providing additional support and stability to the entire device. The lifting design of the foot 7 can provide effective ground support when needed, greatly enhancing the stability of the entire device during pulling out and maintenance, avoiding shaking or falling. By lifting and sliding the foot 7 on the leg 6, the device can be adjusted according to the flatness and height difference of the ground to ensure that the device always remains stable. When the device is pulled out and the generator is in a maintenance state, the leg 6 and the foot 7 can share part of the weight and pressure, reducing the burden on the slide structure and prolonging its service life. Stable support reduces the safety risks that may be caused by unstable devices, ensuring the safety of maintenance personnel during operation.

[0057] Further, the leg 6 and the foot 7 are threadedly connected, and the universal wheel 8 is arranged at the bottom of the foot 7, which is used to roll against the ground.

[0058] In this embodiment, when the mobile device is needed, the position of the supporting leg 7 on the supporting leg 6 is adjusted by rotating the supporting leg 7, so that the universal wheel 8 rolls in contact with the ground. During the process of pushing the generator back into the inner cavity 101 of the shelter, if there is a slight lateral deviation, the universal wheel 8 can be used for fine adjustment. The universal wheel 8 can easily cope with the slight lateral displacement of the device, without the need to change the direction of the entire device, making the adjustment more convenient and efficient. Compared with directly pushing the device laterally, the universal wheel 8 only needs a small force to achieve, reducing the labor intensity of the operation. The threaded connection of the supporting leg 6 and the supporting leg 7 facilitates the accurate adjustment of the height of the universal wheel 8 and the supporting force of the supporting leg 7 to adapt to different ground conditions and operation requirements. During the installation, disassembly and position adjustment of the device, the device can be quickly moved, saving time and manpower, and improving work efficiency.

[0059] Further, the first supporting rod 9 is arranged on the supporting leg 6 at one end and on the middle beam 5 at the other end, and the first supporting rod 9 is arranged on the two middle beams 5 with the supporting leg 6.

[0060] In this embodiment, when the second sliding frame 3 is pulled out and the supporting leg 6 and the supporting leg 7 play a supporting role, the first supporting rod 9 arranged between the supporting leg 6 and the middle beam 5 forms a stable triangular support structure, effectively improving the stability of the device during use, preventing deformation or damage due to uneven stress. It can share the stress generated from the weight of the generator and the device itself, so that the stress is more evenly distributed in the entire structure, prolonging the service life of the device. It helps to improve the carrying capacity of the device, so that it can better cope with the weight of the generator and various external forces during maintenance operation. The stable structure can reduce the risk of accidents during use of the device, ensuring the safety of maintenance personnel and the normal operation of the equipment.

[0061] Further, the first connecting rod 10 is rotatably arranged on the side rail part 201 at one end; the second connecting rod 11 is rotatably arranged on the sliding clamping edge 301 at one end; the first sleeve rod 12 is rotatably arranged on the first connecting rod 10 at one end, and has a first sliding guide groove 1201 at the other end, the direction of the first sliding guide groove 1201 being along the length direction of the first sleeve rod 12; the second connecting rod 11 has a first sliding part 1101 at one end, the first sliding part 1101 being slidably arranged in the first sliding guide groove 1201; and the first foot block 13 is swingably arranged on one end of the first connecting rod 10.

[0062] In this embodiment, when the second sliding carriage 3 starts to slide outwards, but has not yet reached the full length of pull-out required for maintenance, the structure composed of the first connecting rod 10, the second connecting rod 11 and the first sleeve rod 12 will first expand, causing the first foot block 13 to come into contact with the ground and provide support. At this time, due to the special design of the first sliding guide groove 1201 and the first sliding part 1101, even if the first foot block 13 has already provided support, the second sliding carriage 3 can still continue to slide outwards without being affected. In actual operation, when the second sliding carriage 3 just starts to slide a small distance, this structure will automatically expand and support the ground. As the second sliding carriage 3 continues to slide, the structure will adjust its state accordingly, always maintaining the coordination of support and sliding. The support provided before the second sliding carriage 3 is fully extended increases the stability and safety during operation, effectively preventing accidental tilting or shaking of the device when it is not fully in place. The design of the first sliding guide groove 1201 and the first sliding part 1101 ensures that the subsequent sliding of the second sliding carriage 3 is not hindered even if support has already been provided at an early stage, ensuring the continuity and smoothness of the operation. The early support shares part of the weight, reducing the burden on the second sliding carriage 3 and other related components during sliding, reducing the risk of wear and damage, and prolonging the service life of the device.

[0063] Further, a third connecting rod 14 is provided, one end of which is rotatably arranged on the sliding clamping edge 301 on the side away from the machine body 1. The second sleeve rod 15 has a second sliding guide groove 1501, and the third connecting rod 14 has a second sliding part 1401 which is slidably arranged in the second sliding guide groove 1501. The second foot block 16 is swingably arranged at one end of the second sleeve rod 15. The fourth connecting rod 17 is hingedly connected to the first foot block 13 at one end and to the second foot block 16 at the other end. The first connecting rod 10 is configured to swing and drive the third connecting rod 14 to swing through the fourth connecting rod 17.

[0064] In actual operation, in this embodiment, the second sleeve rod 15 begins to fall as soon as the first connecting rod 10 swings, but does not bear the supporting role at first. With the continuous sliding of the second sliding carriage 3, the second foot block 16 finally contacts the ground when reaching the designated position, and the mechanism formed by the first connecting rod 10, the second connecting rod 11, and the first sleeve rod 12 jointly plays a supporting role, at which time an inverted trapezoidal structure is formed between the first sleeve rod 12 and the second sleeve rod 15, and both of the two oblique sides are stably stressed and supported. The second sleeve rod 15 falls when the first connecting rod 10 begins to swing, preparing for subsequent support and saving support response time. Until the second sliding carriage 3 slides to the target length, the second foot block 16 contacts the ground to form support, avoiding the hindrance that may be caused by premature support, while ensuring reliable support at the key position. When reaching the target length, the inverted trapezoidal structure formed by the first sleeve rod 12 and the second sleeve rod 15 enhances the overall structural stability, enabling the device to withstand more external forces in various directions. This design does not affect the normal sliding of the second sliding carriage 3, and can provide strong support in time when needed, ensuring smooth maintenance operation.

[0065] Further, the first elastic member 18 is arranged to act on the inner wall of the first sliding guide groove 1201 at one end and on the first sliding part 1101 at the other end, providing a force for the first sliding part 1101 to move away from the first sliding guide groove 1201; the second elastic member 19 is arranged to act on the inner wall of the second sliding guide groove 1501 at one end and on the second sliding part 1401 at the other end, providing a force for the second sliding part 1401 to move away from the second sliding guide groove 1501.

[0066] In actual operation, in this embodiment, when the second sliding carriage 3 begins to slide and the first connecting rod 10 and the second connecting rod 11 and the third connecting rod 14 act, the elastic force of the first elastic member 18 and the second elastic member 19 can play a role in buffering and auxiliary resetting. The first elastic member 18 and the second elastic member 19 can play a role in buffering during the sliding process of the connecting rod and the sleeve rod, reducing the impact and vibration between the components and protecting the device structure. After the operation is completed, the elastic force of the elastic member helps the first sliding part 1101 and the second sliding part 1401 to return to the initial position, making the device easier to restore to its original state. The continuous force provided by the elastic member can make the connection between the connecting rod and the sleeve rod more tight and stable, improving the reliability of the entire support structure. Under different working conditions and sliding speeds, the elastic member can automatically adjust the force, making the action of the device more stable and adapting to various situations.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
