Description

Technical Field

[0001] This utility model relates to the field of fire equipment maintenance and repair technology, and in particular to a mobile fire extinguisher repair device. Background Technology

[0002] Fire extinguishers, as commonly used fire-fighting equipment, require regular pressure testing and component replacement to ensure their fire-extinguishing performance. Mobile fire extinguisher maintenance units are widely used in fire protection facility maintenance because they can flexibly travel to different locations to carry out maintenance work. These units typically use a maintenance vehicle as their operating platform, with an internal maintenance workbench for carrying out fire extinguisher maintenance operations. A well-planned internal structure can improve maintenance efficiency and meet the needs of batch or decentralized fire extinguisher maintenance.

[0003] Currently, in the use of existing mobile fire extinguisher maintenance devices, the transfer of fire extinguishers within the maintenance vehicle largely relies on manual handling. From the device entrance to the maintenance platform and then to the storage area after maintenance, the fire extinguishers need to be moved manually repeatedly. This not only increases the labor intensity of maintenance personnel but also easily leads to tilting or collisions of fire extinguishers due to improper handling, affecting the continuity of maintenance operations. Especially during batch maintenance, manual transfer is inefficient and makes it difficult to achieve orderly flow of fire extinguishers, thus hindering the overall maintenance progress. Therefore, we propose a mobile fire extinguisher maintenance device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings in the above-mentioned background technology and to propose a mobile fire extinguisher maintenance device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mobile fire extinguisher repair device includes a repair compartment and a repair platform fixedly installed on its inner wall, wherein a repair delivery mechanism is provided at the bottom of the repair compartment.

[0007] The repair mechanism includes a repair platform fixedly installed on the bottom of the repair compartment. The top of the repair platform has a feed chute and a discharge chute, which are connected by an arc-shaped connecting port. Multiple feed shafts are rotatably connected to the inner wall of the feed chute, and multiple discharge shafts are rotatably connected to the inner wall of the discharge chute. Adjacent feed shafts and discharge shafts are connected by chain drive. A conveyor roller is fixedly sleeved on the outer wall of each feed shaft and discharge shaft. A motor is fixedly installed on the outer wall of the repair platform. The output shaft of the motor is fixedly connected to the end of one of the feed shafts. A first spur gear and a second spur gear are fixedly sleeved on the outer wall of each feed shaft and discharge shaft, respectively. Adjacent first spur gears and second spur gears are meshed together.

[0008] Preferably, chain discs adapted to the chain are fitted on the outer walls of both the feed shaft and the discharge shaft.

[0009] Preferably, the distance between two adjacent feed shafts is the same, the distance between two adjacent discharge shafts is the same, and the distance between two adjacent discharge shafts and the distance between two adjacent feed shafts are the same.

[0010] Preferably, a rubber anti-slip sleeve is fixedly fitted on the outer wall of the material conveying roller, and the surface of the rubber anti-slip sleeve is provided with anti-slip texture.

[0011] Preferably, the bottom of the arc-shaped communication port is provided with multiple rotating grooves, and the rotating grooves are tumblingly connected to material transfer balls.

[0012] Preferably, the repair station has a fixed cavity inside, and the chain, the first spur gear, and the second spur gear are all located inside the fixed cavity.

[0013] The beneficial effects of this utility model are as follows:

[0014] The feeding shaft is driven by a motor, which, in conjunction with chain drive and the meshing of the first and second spur gears, drives the conveying rollers in the feeding and discharging troughs to rotate synchronously, thus achieving automatic conveying of fire extinguishers. Rubber anti-slip sleeves prevent slippage during conveying, and the conveying ball bearings assist in a smooth transition at the arc-shaped connecting opening. The fixed cavity protects the transmission components. No manual repeated handling is required, reducing labor intensity, minimizing the risk of fire extinguisher collisions, ensuring orderly flow during batch repairs, and improving overall repair efficiency and operational continuity.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3 A mobile fire extinguisher repair device includes a repair compartment 1 and a repair platform 2 fixedly installed on its inner wall. A repair mechanism is provided at the bottom of the repair compartment 1. The repair mechanism includes a repair platform 3 fixedly installed on the bottom of the repair compartment 1. The top of the repair platform 3 has an inlet trough 4 and an outlet trough 5, which are connected by an arc-shaped connecting port 6. Multiple inlet shafts 7 are rotatably connected to the inner wall of the inlet trough 4, and multiple outlet shafts 7 are rotatably connected to the inner wall of the outlet trough 5. Shaft 8, the two adjacent feed shafts 7 and the two discharge shafts 8 are all connected by chain 9. The outer walls of the feed shafts 7 and the discharge shafts 8 are fixedly sleeved with conveyor rollers 10. The outer wall of the repair table 3 is fixedly installed with a motor 11. The output shaft of the motor 11 is fixedly connected to the end of one of the feed shafts 7. The outer walls of the feed shafts 7 and the discharge shafts 8 are respectively fixedly sleeved with a first spur gear 12 and a second spur gear 13. The adjacent first spur gears 12 and second spur gears 13 are meshed and connected.

[0021] To further explain, the automatic transfer of fire extinguishers is achieved through the repair mechanism. The motor 11 drives the feed shaft 7 to rotate, which in turn drives multiple feed shafts 7 and conveyor rollers 10 to rotate synchronously via the chain 9. At the same time, the first spur gear 12 and the second spur gear 13 mesh to drive the discharge shaft 8 and conveyor rollers 10 to rotate. In conjunction with the arc-shaped connecting port 6, the fire extinguisher is continuously transferred from feeding to discharging, reducing manual handling and improving the efficiency of repair and transfer.

[0022] like Figure 1 As shown, chain discs adapted to the chain 9 are fitted on the outer walls of the feed shaft 7 and the discharge shaft 8.

[0023] To further explain, the chain disc is adapted to the chain 9, which can enhance the transmission stability of the chain 9 with the feed shaft 7 and the discharge shaft 8, prevent the chain 9 from falling off or slipping, ensure that the feed shaft 7 and the discharge shaft 8 operate synchronously and efficiently, and ensure that the conveying process is stable and reliable.

[0024] like Figure 1-3 As shown, the distance between two adjacent feed shafts 7 is the same, the distance between two adjacent discharge shafts 8 is the same, and the distance between two adjacent discharge shafts 8 and the distance between two adjacent feed shafts 7 are the same.

[0025] To further explain, the adjacent feed shaft 7 and discharge shaft 8 are equidistant and have the same spacing, which makes the material conveying roller 10 evenly distributed, providing more stable support and conveying of the fire extinguisher, avoiding tilting or jamming of the fire extinguisher due to spacing differences, and improving the smoothness of conveying.

[0026] like Figure 1 As shown, a rubber anti-slip sleeve 14 is fixedly sleeved on the outer wall of the material conveying roller 10, and anti-slip texture is formed on the surface of the rubber anti-slip sleeve 14.

[0027] To further explain, the rubber anti-slip sleeve and anti-slip texture can increase the friction between the conveying roller 10 and the fire extinguisher, prevent the fire extinguisher from slipping or shifting during the conveying process, ensure its stable passage through the feed chute 4, the arc-shaped connecting port 6 and the discharge chute 5, and improve the conveying accuracy.

[0028] like Figure 1 As shown, multiple rotating grooves 15 are provided at the bottom of the arc-shaped connecting port 6, and the rotating grooves 15 are connected to the material transfer balls 16.

[0029] To further explain, the conveying ball bearing 16 can provide auxiliary support and reduce bottom friction when the fire extinguisher passes through the arc-shaped connecting port 6, making the fire extinguisher turn more smoothly, further avoiding jamming, and improving the smoothness and stability of the conveying.

[0030] like Figure 2 As shown, the repair station 3 has a fixed cavity inside, and the chain 9, the first spur gear 12 and the second spur gear 13 are all located in the fixed cavity.

[0031] To further explain, the fixed cavity can form a closed protection for the chain 9, the first spur gear 12 and the second spur gear 13, preventing dust and debris generated during maintenance from adhering to the transmission components and affecting the transmission effect, while also preventing personnel from contacting the moving parts and improving the safety of the device.

[0032] The functional principle of this utility model can be explained through the following operation methods:

[0033] The user first places the fire extinguisher to be repaired in the feed trough 4 of the repair platform 3, so that the bottom of the fire extinguisher contacts the material transfer roller 10 in the feed trough 4. Then, the user starts the motor 11 on the outer wall of the repair platform 3. The output shaft of the motor 11 drives one of the feed shafts 7 fixed to it to rotate. The feed shaft 7 drives the other feed shafts 7 to rotate synchronously through the chain 9. This causes the material transfer rollers 10 on the outer wall of all the feed shafts 7 to rotate together. The material transfer rollers 10 drive the fire extinguisher to move along the feed trough 4 towards the arc-shaped connecting port 6 through friction.

[0034] When the fire extinguisher moves to the arc-shaped connecting port 6, the material transfer ball 16 in the bottom rotating groove 15 of the arc-shaped connecting port 6 rolls with the fire extinguisher, helping to reduce the friction between the bottom of the fire extinguisher and the arc-shaped connecting port 6. At the same time, the first spur gear 12 on the outer wall of the feeding shaft 7 meshes with the second spur gear 13 on the outer wall of the discharging shaft 8, driving the discharging shaft 8 to rotate synchronously, causing the material transfer roller 10 in the discharging trough 5 to rotate. Under the synergistic effect of the material transfer roller 10 and the material transfer ball 16, the fire extinguisher smoothly passes through the arc-shaped connecting port 6 and enters the discharging trough 5.

[0035] After the fire extinguisher enters the discharge trough 5, it is continuously conveyed by the conveying roller 10 in the discharge trough 5 and moves to a position close to the maintenance platform 2. The user turns off the motor 11, the conveying roller 10 stops running, and then takes the fire extinguisher out of the discharge trough 5 and places it on the maintenance platform 2 for inspection, replacement of parts and other maintenance operations.

[0036] After the fire extinguisher is repaired, the user restarts motor 11, places the repaired fire extinguisher in the feed trough 4, and repeats the above conveying steps to convey the repaired fire extinguisher through feed trough 4, arc-shaped connecting port 6, and discharge trough 5 to the designated collection location, completing one repair conveying process; if continuous repair is required, the fire extinguishers to be repaired can be placed into feed trough 4 in sequence and continuously conveyed through the repair mechanism until all fire extinguishers are repaired and motor 11 is turned off.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
