Description

Technical Field

[0001] The present invention relates to the technical field of cleaning equipment, and particularly to a high-pressure cleaner for fire-fighting equipment maintenance. Background Art

[0002] Fire-fighting equipment refers to various equipment and tools used for preventing, controlling, and extinguishing fires, which together constitute a fire safety system. As an important fire-fighting equipment, a fire hose is a hose mainly used to transport high-pressure water or flame-retardant liquids such as foam. Traditional fire hoses have a rubber lining and are wrapped with linen fabric on the outer surface.

[0003] After the fire hose is used, a large amount of mud and stains are easily attached to its surface. If it cannot be cleaned in time or is not cleaned thoroughly, it is very easy to cause the fire hose to mildew and affect normal use, which requires the use of high-pressure cleaning methods.

[0004] After the fire hose is used, it is usually wound up. During this process, creases will inevitably form. These creases not only increase the difficulty of cleaning, but also because the hose is in a flat state when not in use and the width of its two sides is extremely narrow, making the cleaning work more difficult. This special shape makes it difficult to reach all parts of the hose during cleaning, especially the creases and the flat two sides, thus increasing the difficulty of thorough cleaning and making it difficult to ensure that the fire hose is cleaned thoroughly. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-pressure cleaner for fire-fighting equipment maintenance to solve the problem that because the hose is in a flat state when not in use and the width of its two sides is extremely narrow, making the cleaning work more difficult. This special shape makes it difficult to reach all parts of the hose during cleaning, especially the creases and the flat two sides, thus increasing the difficulty of thorough cleaning and making it difficult to ensure that the fire hose is cleaned thoroughly.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions: A high-pressure cleaner for fire-fighting equipment maintenance includes a cleaning tank assembled in a frame.

The fixed clamp is connected to a tube supporting ring slidably sleeved on the hose guiding rod through a pull rope. It also includes a winding mechanism installed at the end of the hose guiding rod. One end of the pull rope is fixed in a reel on the winding mechanism. By winding the pull rope with the reel, the fixed clamp is pulled to move the hose forward along the hose guiding rod after being cleaned by the high-pressure cleaning mechanism, and after the cleaning is completed, the pull rope is further wound to make the tube supporting ring move inside the hose, so that the inner cavity of the hose can be cleaned in an expanded state.

[0007] As a further description of the above technical solution: The pipe walking mechanism further includes a support assembly sleeved on the surface of the pipe walking rod. The support assembly includes a support pipe. The bottom of the support pipe is rotatably connected to an electric push rod. The bottom end of the electric push rod is installed on the inner bottom wall of the cleaning tank. The electric push rod cooperates with the support pipe to drive the pipe walking rod to incline downward when the fixed clamp moves and incline upward when the pipe support ring moves.

[0008] As a further description of the above technical solution: Two water channels are opened in the pipe walking rod. A plurality of water outlet holes are opened on the inner wall of the water channel, so that the inner cavity can be flushed after the water belt is completely sleeved on the surface of the pipe walking rod.

[0009] As a further description of the above technical solution: The pipe walking mechanism further includes three guide rods inserted into the guide chute. The three guide rods are respectively rotatably connected to the fixed clamp and the two pipe support rings. One end of the pull rope passing through the guide rod in the fixed clamp is fixed to the guide rod in the pipe support ring. A knob stud is threadedly connected to the guide rod in the fixed clamp, and the end of the knob stud penetrating into the guide rod abuts against the pull rope.

[0010] As a further description of the above technical solution: A positioning bolt is threadedly connected to one end of the pipe walking rod close to the pipe support ring. The end of the positioning bolt penetrating into the guide chute is threadedly connected to the guide rod on the outer pipe support ring, so that the pipe support ring keeps its position fixed when the fixed clamp moves.

[0011] As a further description of the above technical solution: The folded part of the pull rope is located in the guide chute between the pipe support ring and the fixed clamp, and a bottom plate is clamped on one side of the inner wall bottom of the guide chute close to the folded part of the pull rope, so that the folded part of the pull rope is kept in the guide chute when not in use.

[0012] As a further description of the above technical solution: The winding mechanism includes a support seat fixed to the end of the pipe walking rod. The reel is rotatably connected to the support seat. A motor for driving the reel to rotate is assembled on the outer wall of the cleaning tank. The output end of the motor is fixed with a connecting shaft, and one end of the connecting shaft is connected to one end of the reel through a universal joint.

[0013] As a further description of the above technical solution: The high-pressure cleaning mechanism includes a mounting frame installed on the inner wall of the cleaning box, two water spray ring pipes are fixed on the mounting frame, water outlet holes are opened on the outer walls of the water spray ring pipes, connecting pipes are fixed on the water inlets of the two water spray ring pipes, and one end of the two connecting pipes is commonly connected to a rear three-way solenoid valve.

[0014] As a further description of the above technical solution: The high-pressure cleaning mechanism also includes a water pump installed in the cleaning box, the input end of the water pump is fixedly connected to a water outlet pipe, the input end of the water pump is fixedly connected to a water inlet pipe, and the water inlet pipe is connected to an external water source.

[0015] As a further description of the above technical solution: One end of the water outlet pipe is connected to two water distribution pipes through a front three-way solenoid valve, one end of one of the water distribution pipes is connected to one end of the rear three-way solenoid valve, and a three-way pipe connected to the water flow chamber is fixed to one end of the pipe rod close to the support seat, and one end of the three-way pipe is connected to one end of the other water distribution pipe.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: By means of the arranged pipe-feeding mechanism and the high-pressure cleaning mechanism, it is realized that the cleaned water hose can be moved and unfolded on the pipe-feeding rod by means of a fixed clamp. During cleaning, the water hose is stretched to a cylindrical shape when passing through the pipe-supporting ring, so that the folds and edges are unfolded, so that the water sprayed through the water-spraying ring can completely contact the surface of the water hose, and the surface of the water hose is fully cleaned, which greatly improves the cleaning effect, avoids stains being left in the folds on the surface of the water hose, and avoids the edges of the water hose from being not cleaned properly. At the same time, after the surface of the water hose is cleaned, the inner cavity of the water hose can be cleaned by injecting water into the pipe rod. After cleaning, the water hose can be squeezed by moving the pipe support ring and cooperating with the support pipe to reduce the residual moisture in the water hose after high-pressure water cleaning.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figure 1 - Figure 9 shown, what the present invention provides: A high-pressure cleaner for fire-fighting equipment maintenance, including a cleaning tank 10 assembled in a frame, a high-pressure cleaning mechanism 50 assembled on the inner wall of the cleaning tank 10, and a pipe walking mechanism 30 assembled in the cleaning tank 10; The pipe walking mechanism 30 includes a pipe walking rod 31, and a fixed clamp 33 is slidably installed on the pipe walking rod 31 through a guide chute 32, so that the end of the water hose sleeved on the pipe walking rod 31 can be fixed, and the fixed clamp 33 is connected to a pipe support ring 34 slidably sleeved on the pipe walking rod 31 through a pull rope 35; Preferably, studs are threadedly connected to the extending portions on both sides of the fixing clip 33. One end of the stud passing through the extending portion is rotatably connected to a contact plate. After the end of the water hose is sleeved on the surface of the pipe walking rod 31, the two sides of its end are attached to the two sides of the fixing clip 33, and then the stud is tightened, so that the contact plate gradually contacts the surface of the water hose, and then presses against the water hose to fix its end on the fixing clip 33. Thus, the fixing clip 33 can drive the cleaned water hose to move along the pipe walking rod 31. It should be noted that: the connectors at both ends of the water hose need to be removed before fixing; Specifically, when the surface of the water hose is cleaned by the high-pressure cleaning mechanism 50, the water hose moves driven by the fixing clip 33. Similarly, when the water hose passes through the pipe supporting ring 34, it will be fully expanded into a cylindrical shape, and its surface can be fully cleaned in this state; Such as Figure 1 、 Figure 2 、 Figure 5 、 Figure 7 and Figure 9 As shown in figures, the high-pressure cleaning mechanism 50 includes a mounting rack installed on the inner wall of the cleaning tank 10. Two spray ring pipes 52 are fixed on the mounting rack. Water outlet holes are formed on the outer wall of the spray ring pipe 52. Connecting pipes are fixed on the water inlets of the two spray ring pipes 52. One ends of the two connecting pipes are jointly connected to a rear three-way solenoid valve 53. Preferably, the rear three-way solenoid valve 53 is a proportional solenoid valve, which can control the flow rate into the spray ring pipe 52 to make the water output of the two spray ring pipes 52 different; The high-pressure cleaning mechanism 50 further includes a water pump 51 installed in the cleaning tank 10. Preferably, the water pump 51 is a high-pressure water pump. The input end of the water pump 51 is fixedly communicated with a water outlet pipe, and the input end of the water pump 51 is fixedly communicated with a water inlet pipe. The water inlet pipe is communicated with an external water source. One end of the water outlet pipe is connected to two water distribution pipes through a front three-way solenoid valve 54. One end of one of the water distribution pipes is connected to one end of the rear three-way solenoid valve 53. One end of the pipe walking rod 31 close to the support seat 41 is fixed with a three-way pipe communicated with the water flow cavity 37, and one end of the three-way pipe is connected to one end of the other water distribution pipe; Further in detail, two water flow cavities 37 are formed in the pipe walking rod 31. A plurality of water outlet holes are formed on the inner wall of the water flow cavity 37, so that the inner cavity can be flushed after the water hose is completely sleeved on the surface of the pipe walking rod 31; After the cleaning of the water hose surface is completed, the three-way solenoid valve 54 at the front controls the connection between the water outlet pipe and the water distribution pipe communicating with the water flow cavity 37. At this time, the external cleaning water is sent into the water flow cavity 37 under the action of the water pump 51, and then sprayed into the inner cavity of the water hose to perform high-pressure cleaning on the inner cavity of the water hose.

[0021] As Figure 1 , Figure 2 , Figure 3 and Figure 7 shown, the pipe walking mechanism 30 further includes a support assembly 20 sleeved on the surface of the pipe walking rod 31. The support assembly 20 includes a support pipe 21. The bottom of the support pipe 21 is rotatably connected to an electric push rod 22, and the bottom end of the electric push rod 22 is installed on the inner bottom wall of the cleaning tank 10; More specifically, the electric push rod 22 and the support pipe 21 can drive the pipe walking rod 31 to tilt downward when the fixed clamp 33 moves and tilt upward when the pipe support ring 34 moves. And at least three electric push rods 22 are provided, corresponding to the two ends and the middle part of the support pipe 21 respectively. At the same time, the support pipe 21 is composed of two half pipes in a detachable manner, which is convenient for the installation of the pipe walking rod 31. And the pipe walking rod 31 and the support pipe 21 have a certain toughness, and the support pipe 21 can support the pipe walking rod 31; Specifically, when cleaning the water hose surface, the electric push rods 22 at the middle position and the tail end drive the support pipe 21 to tilt upward with the front end as the fulcrum, so that the water droplets dripping from the surface of the water hose entering the support pipe 21 after cleaning can flow towards the front end of the support pipe 21 under the action of gravity; After the cleaning of the water hose surface is completed, when cleaning the inside of the water hose, the electric push rods 22 at the middle position and the tail end drive the support pipe 21 to tilt downward with the front end as the fulcrum, so that the fixed clamp 33 is at a low position. It should be noted that when cleaning the inside of the water hose, the tail end of the water hose needs to be fixed to the front end of the pipe walking rod 31 through a pipe clamp first.

[0022] As Figure 3 , Figure 4 , Figure 6 and Figure 8 shown, the pipe walking mechanism 30 further includes three guide rods 36 inserted into the guide chute 32. The three guide rods 36 are respectively rotatably connected to the fixed clamp 33 and the two pipe support rings 34. One end of the pull rope 35 passing through the guide rod 36 in the fixed clamp 33 is fixed to the guide rod 36 in the pipe support ring 34. A knob stud 39 is threadedly connected to the guide rod 36 in the fixed clamp 33, and the end of the knob stud 39 inserted into the guide rod 36 abuts against the pull rope 35; One end of the pipe walking rod 31 close to the pipe support ring 34 is threadedly connected with a positioning bolt 38. The end of the positioning bolt 38 inserted into the guide chute 32 is threadedly connected to the guide rod 36 on the outer pipe support ring 34, so that the pipe support ring 34 remains fixed in position when the fixed clamp 33 moves; The folded part of the pull rope 35 is located in the guiding chute 32 between the support pipe ring 34 and the fixed clamp 33. And a bottom plate is clamped on one side of the inner wall bottom of the guiding chute 32 near the folded part of the pull rope 35, so that the folded part of the pull rope 35 is kept in the guiding chute 32 when not in use. Particularly, when the end of the water hose is sleeved on the pipe walking rod 31 and moves to the front of the fixed clamp 33 through the support pipe ring 34, first take out the bottom plate, and then fix the end of the water hose on the fixed clamp 33; More specifically, in the initial state, the fixed clamp 33 and the support pipe ring 34 are located at the front end position. In this state, the guide rod 36 on one of the support pipe rings 34 is threadedly connected with the positioning bolt 38, so that the positions of the two support pipe rings 34 are fixed, avoiding the movement of the support pipe ring 34 due to the action of friction when the fixed clamp 33 moves with the water hose. At the same time, when the fixed clamp 33 moves with the water hose to the rear end, in this state, the folded part of the pull rope 35 will also unfold. After the internal cleaning of the water hose is completed, unscrew the positioning bolt 38 and the knob stud 39 to release the fixation of the support pipe ring 34 and the pull rope 35. At this time, when the pull rope 35 continues to move, it will pull the support pipe ring 34 to move along the pipe walking rod 31 inside the water hose. At this time, the support pipe ring 34 cooperates with the support pipe 21 to squeeze the water hose, so that the water on the water hose during cleaning will be squeezed out and flow away along the downwardly inclined support pipe 21.

[0023] As Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 7 shown, more specifically, it further includes a winding mechanism 40 installed at the end of the pipe walking rod 31. One end of the pull rope 35 is fixed in the reel 43 on the winding mechanism 40. By winding the pull rope 35 through the reel 43, the fixed clamp 33 is made to pull the water hose to move forward along the pipe walking rod 31 after being cleaned by the high-pressure cleaning mechanism 50, and after the cleaning is completed, the pull rope 35 is continuously wound to make the support pipe ring 34 move inside the water hose, so that the inner cavity of the water hose can be cleaned in the expanded state; The winding mechanism 40 includes a support seat 41 fixed at the end of the pipe walking rod 31. The reel 43 is rotatably connected inside the support seat 41. An electric motor 42 for driving the reel 43 to rotate is assembled on the outer wall of the cleaning box 10. The output end of the electric motor 42 is fixed with a connecting shaft. One end of the connecting shaft is connected to one end of the reel 43 through a universal joint 44. Particularly, in order to improve the stability between the connecting shaft and the reel 43, a bearing seat is sleeved on the surface of the connecting shaft, and one end of the bearing seat is fixed to the inner wall of the cleaning box 10; Specifically, when cleaning the surface of the water hose, the reel 43 is rotated by the motor 42, and then the pulling rope 35 is wound up, so that the fixing clip 33 drives the water hose to move on the surface of the pipe walking rod 31. When the surface cleaning of the water hose is completed and the inner cavity of the water hose is cleaned, first screw out the knob stud 39 to release the fixation of the pulling rope 35, and then screw out the positioning bolt 38 to release the fixation of the support pipe ring 34. Then continue to rotate the reel 43 by the motor 42 to continue winding up the pulling rope 35. At this time, the pulling rope 35 will pull the support pipe ring 34 to move inside the water hose along the pipe walking rod 31. During the movement, the water hose is expanded to abut against the inner wall of the support pipe 21, and the cleaned water hose is squeezed in cooperation to squeeze out as much residual water as possible after the water hose is cleaned. When the squeezing is over, release the fixation of the hose clamp and the fixing clip 33 on both ends of the water hose, then pull out the water hose from the end far away from the winding mechanism 40, and then perform subsequent drying operations; Preferably, a folding frame is slidably connected to the surface of the cleaning box 10, and a waterproof cloth that can be contracted and unfolded together with it is provided on the surface of the folding frame. When cleaning the surface of the water hose, the folding frame is unfolded. At this time, the waterproof cloth can block the splashing water during the cleaning process. Specifically, a fan is installed at the front end of the folding frame. After the inside and outside of the water hose are cleaned and squeezed, the upper half of the support pipe 21 is removed, and then the fan is turned on to blow the water hose to dry it inside the box. After drying, release the fixation of the hose clamp and the fixing clip 33 on both ends of the water hose, then pull out the water hose from the end far away from the winding mechanism 40, and wind it up manually or by a winding device; Specifically, the guide rods 36 on the two support pipe rings 34 are connected together by a connecting rope, so that the two support pipe rings 34 can move smoothly together at the bent part of the pipe walking rod 31; It should be noted that after the water hose is pulled out from the pipe walking rod 31, first move the support pipe ring 34 towards the front end of the pipe walking rod 31, and pull the pulling rope 35 together during the movement. After the support pipe ring 34 returns to the initial state, tighten the positioning bolt 38 to fix the position of the support pipe ring 34, and then tighten the knob stud 39 to fix the pulling rope 35 to the fixing clip 33. Then pull the pulling rope 35 on one side of the support pipe ring 34 upward from the guiding chute 32. During the pulling process, gradually pull the fixing clip 33 to the initial state, then fold the pulling rope 35 pulled out from the guiding chute 32 and put it back into the guiding chute 32, and finally snap the bottom plate back into the bottom of the guiding chute 32 to support the folded pulling rope 35.

[0024] Specifically, when this high-pressure cleaner for fire-fighting equipment maintenance is in operation / in use: 1. Preparation stage: Remove the connectors at both ends of the fire hose, sleeved the fire hose on the surface of the pipe walking rod 31, and fix the end of the fire hose with the fixing clip 33 to ensure that equipment such as the high-pressure cleaning mechanism 50 in the cleaning box 10 is in a standby state; 2. Hose surface cleaning: Control the water outlet pipe to be connected to the water distribution pipe communicating with the water spraying ring pipe 52 through the first three-way solenoid valve 54, then start the water pump 51 to send the external cleaning water into the water spraying ring pipe 52 to perform high-pressure cleaning on the hose surface. At the same time, the motor 42 drives the reel 43 to rotate, winds up the pull rope 35, so that the fixing clip 33 drives the hose to move on the pipe walking rod 31 and is cleaned by the high-pressure cleaning mechanism 50; 3. Hose internal cleaning: After the hose surface cleaning is completed, control the water outlet pipe to be connected to the water distribution pipe communicating with the water flow cavity 37 through the first three-way solenoid valve 54, then start the water pump 51 to send the external cleaning water into the water flow cavity 37 to perform high-pressure cleaning on the hose inner cavity. At this time, adjust the inclination angle of the support pipe 21 through the electric push rod 22 to make the fixing clip 33 at a low position to facilitate the cleaning of the hose inner cavity; 4. Hose squeezing and water removal: After the internal and external cleaning of the hose is completed, unscrew the positioning bolt 38 and the knob stud 39 to release the fixation of the pull rope 35 and the support pipe ring 34, and continue to drive the reel 43 to rotate through the motor 42 to wind up the pull rope 35, so that the support pipe ring 34 moves on the pipe walking rod 31 and cooperates with the support pipe 21 to squeeze the hose to remove the residual water; 5. Hose drying and winding: After squeezing, release the fixation of the hose clamps and the fixing clip 33 on both ends of the hose, pull out the hose from the end far from the winding mechanism 40 for subsequent drying operation, and after drying, wind up the hose; 6. Reset stage: Move the support pipe ring 34 towards the front end of the pipe walking rod 31 to reset to the initial state, and re-tighten the positioning bolt 38 and the knob stud 39, fold the pull rope 35 and put it back into the guide chute 32, and re-insert the bottom plate into the bottom of the guide chute 32.
