In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0045] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0046] like Figure 1-Figure 6 As shown, the present invention provides a fire alarm facility maintenance device, including a base 1, a supporting mechanism 2 and a folding assembly 3, the base 1 is provided with a storage groove 100, the supporting mechanism 2 includes a driving assembly 21 and a bearing platform 22, the driving assembly 21 is arranged in the storage groove 100, and can drive the bearing platform 22 to rise and fall in the vertical direction, and the bearing platform 22 is configured to accommodate maintenance tools; the folding assembly 3 includes at least two folding ladders 31, the folding ladders 31 are movably connected in sequence, and the folding assembly 3 has a storage state and an unfolding state. In the storage state, the multiple folding ladders 31 are close to each other and can be stored in the storage groove 100. In the working state, the multiple folding ladders 31 are arranged in a straight line, and the folding ladders 31 at both ends, the folding ladder 31 at one end can abut against the base 1, and the folding ladder 31 at the other end can abut against the bearing platform 22.

[0047] The fire alarm facility maintenance device of the present invention, when not in use, the multiple folding ladders 31 of the folding assembly 3 are close to each other and can be stored in the storage groove 100 of the base 1, so that the entire fire alarm facility maintenance device is relatively compact, effectively reducing the occupied space, and is easy to store; when it is necessary to climb up, the driving assembly 21 drives the bearing platform 22 to move away from the base 1 in the vertical direction, and the multiple folding ladders 31 are unfolded along the same extension direction and arranged in a straight line. The folding ladders 31 at one end of the folding ladders 31 abut against the base 1, and the folding ladders 31 at the other end abut against the bearing platform 22, which can be used for maintenance personnel to climb. The entire fire alarm facility maintenance device does not rely on other auxiliary supports such as walls, and has strong applicability; in addition, the maintenance personnel can place the maintenance tools on the bearing platform 22 in advance and deliver them to the required height through the driving mechanism, without having to carry tools when climbing, which reduces the burden on the operator, provides more convenient operating conditions for the maintenance personnel, and is conducive to improving maintenance efficiency.

[0048] like Figure 2 As shown, the folding ladder 31 includes two ladder beams 311 and a plurality of pedals 312. The two ladder beams 311 are arranged at intervals, and the plurality of pedals 312 are sandwiched between the two ladder beams 311. The pedals 312 are provided with anti-skid parts 3121 to increase the friction force when the maintenance personnel climb, thereby improving safety.

[0049] Specifically, the folding assembly 3 further includes a plurality of connecting members 33 and a plurality of limiting members 34. Two connecting members 33 are arranged as a group on opposite sides of the folding assembly 3. Two adjacent folding ladders 31 are connected by rotation through a group of connecting members 33, and limiting members 34 are arranged on opposite sides of one of the folding ladders 31. When the folding assembly 3 is in the unfolded state, the two connecting members 33 abut against the two limiting members 34 one by one. When the fire alarm facility maintenance device needs to be used, the folding ladder 31 is rotated around the connecting member 33 to unfold. As the unfolding process proceeds, the connecting member 33 gradually approaches and finally abuts against the limiting member 34. The limiting member 34 plays a role in limiting the excessive unfolding of the folding ladder 31, ensuring that the folding assembly 3 can remain stable in the unfolded state, and providing a safe and reliable climbing platform for the operator.

[0050] In this embodiment, three folding ladders 31 are provided.

[0051] In other embodiments, two folding ladders 31 may be provided, and the number of the folding ladders 31 is not specifically limited herein.

[0052] In other embodiments, multiple folding ladders 31 can also be slidably connected in sequence. When in use, the folding ladders 31 are pulled out in sequence so that the multiple folding ladders 31 are arranged in a straight line. When stored, the folding ladders 31 are pushed back in sequence so that the multiple folding ladders 31 are close to each other.

[0053] Specifically, a hanging part 35 is also provided on the folding ladder 31 at the end of the folding component 3. When the folding component 3 is in the unfolded state, the hanging part 35 can be hung on the supporting platform 22, so that the folding component 3 can withstand greater pressure and is not prone to sliding during use, providing more reliable support for maintenance personnel.

[0054] Specifically, Figure 3 As shown, the folding assembly 3 further includes a handle 36 , which is disposed on one of the folding ladders 31 . When the folding assembly 3 is in the storage state, the maintenance personnel can lift the folding assembly 3 by the handle 36 and put it into or take it out of the storage slot 100 .

[0055] Specifically, Figure 3 As shown, the folding assembly 3 further includes two sliders 32, which are arranged on opposite sides of one of the folding ladders 31. Two limiting grooves 1000 are arranged on the inner wall of the storage slot 100, and the limiting grooves 1000 extend from the notch of the storage slot 100 toward the bottom of the storage slot 100. When the folding assembly 3 is in the storage state, the two sliders 32 can be inserted into the two limiting grooves 1000 one by one. The two sliders 32 correspond to the two limiting grooves 1000 one by one, so that the folding assembly 3 in the storage state can be accurately positioned and stored in the storage slot 100, avoiding uneven storage due to position offset. At the same time, the close cooperation between the sliders 32 and the limiting grooves 1000 can effectively prevent the folding assembly 3 from shaking in the storage slot 100, ensuring that the fire alarm facility maintenance device remains stable during movement or storage.

[0056] In this embodiment, the cross-sections of the limit groove 1000 and the slider 32 are both trapezoidal, and the hypotenuse of the trapezoid can provide a certain guiding and restraining effect, so that the slider 32 can better maintain stability in the limit groove 1000 and is not prone to shaking left and right or falling out of the limit groove 1000.

[0057] In this embodiment, the storage slot 100 is divided into a first storage slot and a second storage slot with the limit slot 1000 as the dividing line. The driving component 21 is located in the first storage slot, and the folding component 3 is located in the second storage slot to prevent the folding component 3 from colliding with the driving component 21 during the movement of the fire alarm facility maintenance device.

[0058] In this embodiment, the limiting groove 1000 extends in the vertical direction, and the length of the limiting groove 1000 is not less than the length of the folding ladder 31. The limiting groove 1000 extending in the vertical direction enables the folding ladder assembly 3 to minimize its space occupation in the storage groove 100, making the entire fire alarm facility maintenance device more compact; and, because the length of the limiting groove 1000 is not less than the length of the folding ladder 31, the folding assembly 3 can be fully extended into the storage groove 100 in the storage state, thereby preventing the folding assembly 3 from being damaged by collision due to partial exposure when the fire alarm facility maintenance device is moved.

[0059] More specifically, the fire alarm facility maintenance device further includes two fixing rods, a slider 32 is rotatably connected to a folding ladder 31 at one end of the folding assembly 3, and the slider 32 is provided with a connecting hole 320, and the two sliders 32 can be partially extended into the two limiting grooves 1000 one by one, so that the connecting holes 320 are located outside the limiting grooves 1000, and the two fixing rods can be passed through the two connecting holes 320 one by one and abut against the top surface of the base 1. Since the base 1 itself has a certain height, a higher fixing point can be provided for the folding assembly 3, so that the folding assembly 3 can directly extend from the top of the base 1 to the bearing platform 22 when unfolded, thereby reducing the number of folding ladders 31, so that the folding assembly 3 occupies less space when folded, and is more convenient for storage and transportation.

[0060] See also Figure 3 In this embodiment, the driving assembly 21 includes a cylinder 211 and a piston rod 212. The cylinder 211 is disposed in the storage tank 100, the piston rod 212 is connected to the output end of the cylinder 211, and the carrier 22 is connected to the piston rod 212. By controlling the air intake and air pressure of the cylinder 211, the extension speed and stroke of the piston rod 212 can be accurately controlled, thereby smoothly adjusting the height of the carrier 22.

[0061] In other embodiments, the driving assembly 21 includes a hydraulic cylinder and a hydraulic rod. The hydraulic cylinder is fixedly disposed in the storage groove 100, the hydraulic rod is connected to the output end of the hydraulic cylinder, and the supporting platform 22 is connected to the hydraulic rod.

[0062] Specifically, Figure 3 and Figure 5 As shown, the carrying platform 22 is provided with a storage slot 221, and the carrying platform 22 is movably connected to a protective cover 23 through a hinge, and the protective cover 23 can cover the slot of the storage slot 221. The storage slot 221 provides a convenient tool storage space for maintenance personnel, and the protective cover 23 can prevent the tools from falling from the storage slot 221 due to bumps.

[0063] Specifically, Figure 4As shown, the fire alarm facility maintenance device also includes a running wheel 4, which is arranged at the bottom of the base 1. By providing the running wheel 4, the maintenance personnel can push the fire alarm facility maintenance device to different working areas, which not only reduces physical exertion, but also makes the work more efficient.

[0064] In this embodiment, the running wheel 4 is connected to the bottom of the base 1 through an adapter, and the adapter can rotate horizontally relative to the base 1, so that the fire alarm facility maintenance device can flexibly adjust its direction during movement.

[0065] In this embodiment, four running wheels 4 are provided, the bottom surface of the base 1 is rectangular, and the four running wheels 4 are respectively arranged at four corner points of the bottom surface of the base 1 .

[0066] In other embodiments, six running wheels 4 may be provided, one running wheel 4 is provided at each of the four corner points of the bottom surface of the base 1, and one running wheel 4 is provided at each of the midpoints of the two longer sides. The number and the setting positions of the running wheels 4 are not specifically limited here.

[0067] More specifically, if Figure 4 As shown, the fire alarm facility maintenance device also includes a plurality of support components 5, and the support components 5 include a connecting block 51 and a support rod 52. The connecting block 51 is fixedly arranged on the base 1, and the support rod 52 is adjustably connected to the connecting block 51. The support rod 52 has a supporting position and a retracted position. When the support rod 52 is at the supporting position, the support rod 52 abuts against the reference plane. When the support rod 52 is at the retracted position, the walking wheel 4 abuts against the reference plane, and the support rod 52 is separated from the reference plane.

[0068] When the fire alarm facility maintenance device reaches the working position, the maintenance personnel can adjust the support rod 52 to the supporting position so that the support rod 52 rests on the reference plane. At this time, the support rod 52 can bear the weight of the fire alarm facility maintenance device, provide stable support for the fire alarm facility maintenance device, and prevent the fire alarm facility maintenance device from sliding during the climbing process; when the fire alarm facility maintenance device needs to be moved, the support rod 52 can be adjusted to the retracted position so that the support rod 52 is separated from the reference plane. At this time, the walking wheel 4 is in contact with the reference plane, and the fire alarm facility maintenance device can be freely moved by the walking wheel 4.

[0069] In this embodiment, the support rod 52 is screwed to the connection block 51. By rotating the support rod 52, the position of the support rod 52 can be flexibly adjusted to adapt to different reference surface conditions, ensuring that the device can remain level and stable under various conditions. In addition, the threaded fit between the support rod 52 and the connection block 51 can effectively prevent the two from relative displacement or loosening, thereby increasing the stability of the entire fire alarm facility maintenance device when in use.

[0070] In other embodiments, a pin hole may be provided on the connection block 51, and a pin hole may be provided at a corresponding position of the support rod 52, and the connection is achieved by inserting a cylindrical pin. When in use, the pin is inserted into the two holes to fix the position of the support rod 52, and the pin is pulled out when adjusting, and then inserted and fixed after adjustment. This method has a stable connection, is easy to disassemble, and is convenient for quickly adjusting the position of the support rod 52.

[0071] In this embodiment, four support components 5 are provided. The base 1 is a cube. The four support components 5 are disposed on two opposite sides of the base 1 .

[0072] In other embodiments, eight support components 5 may also be provided, which are disposed on four sides of the base 1 . The number and the location of the support components 5 are not specifically limited herein.

[0073] More specifically, if Figure 4 As shown, the support assembly 5 further includes an anti-skid pad 53, which is connected to one end of the support rod 52 away from the base 1. The provision of the anti-skid pad 53 increases the friction between the fire alarm facility maintenance device and a reference surface such as the ground, effectively preventing the fire alarm facility maintenance device from sliding or shifting during operation, and further improving the stability of the fire alarm facility maintenance device.

[0074] Specifically, Figure 5 As shown, the fire alarm facility maintenance device also includes a fixing seat 6 and a support member 7. The fixing seat 6 is arranged on the top of the bearing platform 22. The support member 7 is connected to the fixing seat 6 in an adjustable manner in the vertical direction, and the support member 7 can abut against the fire alarm facility. When the fire alarm facility needs to be disassembled, the support member 7 can be adjusted so that the support member 7 abuts against the fire alarm facility. At this time, the maintenance personnel do not need to hold the fire alarm facility by hand for disassembly, which further improves the convenience of the maintenance personnel's operation.

[0075] In this embodiment, the fixing seat 6 is provided with a threaded hole, and the supporting member 7 is provided with an adaptable external thread. By rotating the supporting member 7 to screw it into or out of the threaded hole, its position adjustment in the vertical direction is achieved.

[0076] In other embodiments, the support member 7 and the fixing seat 6 may be connected via an electric push rod, and the vertical position of the support member 7 may be adjusted by controlling the extension and retraction of the electric push rod.

[0077] Specifically, Figure 5As shown, the fixing seat 6 includes a tube body 61 and a movable disk 62. The tube body 61 is fixedly connected to the top of the bearing platform 22, and the movable disk 62 is rotatably connected to the tube body 61. The support member 7 is screwed to the movable disk 62 and extends into the tube body 61. When the fire alarm facility needs to be disassembled, the maintenance personnel fix the movable disk 62 by hand, rotate the support member 7 so that the support member 7 rises in the vertical direction to support the fire alarm facility, which is convenient for disassembly; after disassembly, the support member 7 is reversely rotated to drive the fire alarm facility to descend, and then the movable disk 62 is rotated to drive the fire alarm facility to rotate, so that the back and some obscured parts of the side of the fire alarm facility can be close to the maintenance personnel during the rotation process, so as to facilitate the maintenance personnel to clean and inspect.

[0078] In this embodiment, a plurality of handles are fixedly connected to the side surface of the movable disk 62, so that the maintenance personnel can apply force more conveniently when rotating the movable disk.

[0079] Optionally, the fire alarm facility maintenance device further includes a smoke generator, and a receiving groove is provided at one end of the support member 7 away from the fixed seat 6, and the smoke generator is provided in the receiving groove. During the maintenance process, the maintenance personnel can use the smoke generator to generate smoke to check whether the fire alarm facility can normally sense the smoke and send out an alarm signal in time, so as to ensure that the fire alarm facility is in good working condition. It should be noted that the smoke generator is a mature technology in this field.

[0080] In this embodiment, the support member 7 includes a threaded tube 71 and a pressure plate 72 . The threaded tube 71 is threadedly connected to the movable plate 62 . The pressure plate 72 is sleeved on one end of the threaded tube 71 facing the fire alarm facility, and the receiving groove is arranged on the pressure plate 72 .

[0081] Alternatively, if Figure 5 and Figure 6 As shown, the fire alarm facility maintenance device also includes a fan 8 and a heating wire 9. The carrier 22 is provided with a groove 220 and a mounting groove. The mounting groove is connected to the groove 220 through an air inlet channel. The fan 8 is arranged in the mounting groove, and the heating wire 9 is arranged in the air inlet channel. The fan 8 draws the airflow into the air inlet channel. The airflow is heated by the heating wire 9 in the air inlet channel and becomes hot air. The hot air rises along the groove 220 to dry the fire alarm facility and remove the moisture inside the fire alarm facility, thereby prolonging the service life of the fire alarm facility.

[0082] In this embodiment, two fans 8 are provided, and the side wall of the support platform 22 is provided with two installation slots connected to the air inlet channel, and the two fans 8 are installed in the two installation slots in a one-to-one correspondence.

[0083] In this embodiment, the fixing seat 6 is disposed in the groove 220 .

[0084] More specifically, if Figure 5As shown, the fire alarm facility maintenance device also includes an air inlet hood 10, which has a plurality of air inlet holes. The air inlet hood 10 is arranged on the inner wall of the groove 220 and covers the opening of the air inlet channel away from the fan 8. By setting the air inlet hood 10, the flow rate and flow velocity of the airflow can be limited. Compared with the open state without the air inlet hood, the air inlet holes form a physical barrier to the airflow, preventing insufficient heating due to excessively fast airflow, or heat accumulation near the heating wire 9 due to excessively slow airflow, causing local overheating. In addition, the setting of multiple air inlet holes can promote the airflow to enter the groove 220 in a dispersed and orderly manner, avoiding the concentrated influx of airflow causing local overheating and damage to the fire alarm facility. In addition, the air inlet hood 10 can prevent large particles of dust and debris from entering the air inlet channel from the groove 220, thereby playing a good protective role for the heating wire 9.

[0085] More specifically, the inner wall of the groove 220 opposite to the air inlet cover 10 is inclined, and the inner wall gradually moves away from the air inlet cover 10 from the bottom of the groove 220 to the notch of the groove 220. The airflow coming out of the air inlet cover 10 will be guided to gradually diffuse in the direction away from the air inlet cover 10, and this diffusion mode enables the airflow to more comprehensively cover the fire alarm facilities during the rising process.

[0086] Alternatively, if Figure 3 As shown, the fire alarm facility maintenance device also includes a battery 11, which is disposed in the storage slot 100 and is configured to supply power to the fan 8 and the heating wire 9.
