Description

Technical Field

[0001] This utility model relates to the field of fire protection pipeline maintenance technology, and in particular to a fire protection pipeline maintenance device. Background Technology

[0002] Fire protection facilities refer to fixed facilities such as automatic fire alarm systems, indoor fire hydrants, and outdoor fire hydrants in buildings. Automatic fire protection facilities are divided into electrical automatic facilities and water automatic facilities. Pipelines are also an important part of fire protection facilities. In order to extend the service life of pipelines, maintenance devices are needed to spray paint and maintain fire pipelines.

[0003] Existing fire pipeline maintenance methods involve manually spraying paint onto the pipelines using handheld spray guns. However, this method has several drawbacks. First, the spraying process is limited by the operating angle and field of vision, resulting in numerous blind spots on the pipeline surface. This is especially true for complex areas such as bends and joints, which are difficult to cover evenly. These unsprayed areas lack effective corrosion protection and are highly susceptible to corrosion, accelerating the overall aging of the pipeline, shortening its service life, and leading to frequent repairs and replacements, thus increasing long-term maintenance costs. Second, manual operation requires repeated adjustments to the spray gun angle to suit different parts of the pipeline, making the process cumbersome and labor-intensive. Utility Model Content

[0004] The purpose of this utility model is to provide a fire pipeline maintenance device to solve the problems mentioned above in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a fire pipeline maintenance device, comprising a maintenance platform and a pipeline body, wherein a support frame is fixedly installed on the bottom surface of the maintenance platform, a through groove is opened on the surface of the maintenance platform, and a movable spraying device is provided on one side surface of the maintenance platform, wherein the movable spraying device comprises two support plates fixedly installed on one side surface of the maintenance platform, and a threaded rod is rotatably connected between the two support plates, wherein a motor is fixedly installed on the surface of one of the support plates, and the output end of the motor is fixedly connected to the threaded rod through a coupling.

[0006] Preferably, a slide rod is fixedly installed between the two support plates, and a T-shaped plate is threadedly connected to the surface of the threaded rod. The T-shaped plate is slidably connected to the slide rod by means of the threaded rod.

[0007] Preferably, two connecting rods are fixedly installed on the surface of the T-shaped plate, and a paint storage tank is fixedly installed at the end of the two connecting rods away from the T-shaped plate. The top surface of the paint storage tank is provided with a feed pipe.

[0008] Preferably, two round rods are fixedly installed on one side surface of the paint storage tank, and a hollow ring is fixedly installed at the end of the two round rods away from the paint storage tank. Multiple nozzles are evenly distributed on the annular sidewall of the hollow ring.

[0009] Preferably, a pump is fixedly installed on the top surface of the paint storage tank, a pumping pipe is fixedly installed at the input end of the pump, the end of the pumping pipe away from the pump is connected to the paint storage tank, and a discharge pipe is fixedly installed at the output end of the pump, the end of the discharge pipe away from the pump is connected to the hollow ring.

[0010] The effect achieved by the above components is that multiple nozzles evenly distributed on the sidewall of the hollow ring can spray paint from multiple angles around the pipe. Combined with the horizontal movement driven by the motor, it can fully cover the entire length of the pipe and areas that are difficult to reach by traditional manual spraying, such as bends and joints, avoiding localized corrosion caused by missed spraying and effectively improving the anti-corrosion effect of the pipe.

[0011] Preferably, the surface of the maintenance table is provided with a clamping device, which includes four support rods. The four support rods are symmetrically distributed on the surface of the maintenance table in pairs. An arc-shaped bracket is fixedly installed on the surface of each pair of support rods away from the maintenance table.

[0012] Preferably, uprights are fixedly installed on both sides of the arc-shaped bracket extension, and an arc-shaped clamp is slidably connected between the two uprights.

[0013] Preferably, a U-shaped frame is fixedly installed on both sides of the maintenance platform. A vertical groove is formed on the inner wall surface of the vertical end of the U-shaped frame. A sliding plate is slidably connected inside the vertical groove. A short rod is fixedly installed between the sliding plate and the arc-shaped clamping plate. An electric telescopic rod is fixedly installed on the surface of the top horizontal end of the U-shaped frame. The output end of the electric telescopic rod is fixedly connected to the arc-shaped clamping plate.

[0014] The effect achieved by the above components is as follows: the arc-shaped bracket and the arc-shaped clamp form a ring-shaped clamping structure, which, together with the uniform pressure provided by the electric telescopic rod, can firmly fix the pipe and avoid uneven paint film thickness caused by pipe shaking during the spraying process, thus ensuring accurate paint coverage.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] In this invention, a mobile spraying device is installed, which utilizes multiple nozzles evenly distributed on the sidewall of a hollow ring to spray paint from multiple angles around the pipe. Combined with the horizontal movement driven by a motor, it can fully cover the entire length of the pipe and areas that are difficult to reach by traditional manual spraying, such as bends and joints, avoiding localized corrosion caused by missed spraying and effectively improving the pipe's corrosion resistance. At the same time, the motor drives the threaded rod to move the spraying assembly at a uniform speed along the pipe axis, and the pump stably delivers paint, realizing the automated operation of the spraying process. There is no need for manual handling of the spray gun or repeated angle adjustments, reducing the cumbersome operation process, greatly improving the maintenance efficiency of a single pipe, and reducing the labor intensity of operators.

[0024] Reference Figure 1-4As shown in this embodiment: the surface of the maintenance table 1 is provided with a clamping device 3, which includes four support rods 31. The four support rods 31 are symmetrically distributed on the surface of the maintenance table 1 in pairs. An arc-shaped bracket 32 ​​is fixedly installed on the surface of each pair of support rods 31 away from the maintenance table 1. Uprights 33 are fixedly installed on the extensions on both sides of the arc-shaped bracket 32. An arc-shaped clamping plate 34 is slidably connected between two uprights 33. U-shaped frames 35 are fixedly installed on both sides of the maintenance table 1. A vertical groove 36 is opened on the inner wall surface of the vertical end of the U-shaped frame 35. A sliding connection is made inside the vertical groove 36. A sliding plate 37 is fixedly installed between the sliding plate 37 and the arc-shaped clamp 34. An electric telescopic rod 39 is fixedly installed on the surface of the top horizontal end of the U-shaped frame 35. The output end of the electric telescopic rod 39 is fixedly connected to the arc-shaped clamp 34. The arc-shaped bracket 32 ​​is rubber-wrapped, and its curvature is adapted to the pipe body 5. The surface roughness is Ra3.2μm. The arc-shaped clamp 34 has a rubber lining and its curvature is consistent with that of the arc-shaped bracket 32. The gap between the two is ≤0.2mm. The electric telescopic rod 39 is model DTZ100, with a thrust of 1000N, a stroke of 100mm, and a telescopic speed of 20mm / s.

[0025] Working principle: When using this device, first check the status of each component: confirm that the motor 203 is running normally, the extraction pump 211 is not blocked, and the rubber lining of the arc-shaped clamp 34 is intact. At the same time, according to the diameter of the pipe body 5, ensure that the curvature of the arc-shaped bracket 32 ​​and the clamp 34 are matched to lay the foundation for subsequent stable clamping and uniform spraying. After the inspection is completed, the operator first places the pipe body 5 to be maintained stably on the surface of the two sets of arc-shaped brackets 32, adjusts the position of the pipe body 5 so that its axis is aligned with the center of the hollow ring 209 to ensure uniform force during spraying, and then simultaneously starts the electric telescopic rods 39 on both sides of the maintenance platform 1. The output end of the electric telescopic rod 39 pushes the arc-shaped clamp 34 to slide down along the upright 33, and simultaneously drives the slide plate 37 to move vertically. The pipe moves smoothly within the groove 36. During the downward movement of the arc-shaped clamp 34, its rubber lining makes flexible contact with the surface of the pipe body 5, forming a ring-like clamping action with the arc-shaped bracket 32 ​​until the pipe body 5 is firmly fixed without radial swaying, completing the clamping step. After clamping, the paint collection mechanism, such as a tray, is placed on the surface of the support frame 4, facing the through groove 6 of the maintenance platform 1, to collect excess paint dripping during the spraying process and reduce waste. An appropriate amount of anti-corrosion paint is injected through the feed pipe at the top of the paint storage tank 207, and the sealing cap is tightened to prevent paint evaporation. Then, the extraction pump 211 is started to extract the paint from the paint storage tank 207 through the extraction pipe 212, and transport it to the interior of the hollow ring 209 through the discharge pipe 213, finally passing through the hollow ring. Multiple nozzles 210, evenly distributed on the annular sidewall of pipe 209, spray paint in a mist, initially covering the surface of the pipe body. After the paint is sprayed normally, motor 203 is started. The output end of motor 203 drives threaded rod 202 to rotate through coupling, causing T-shaped plate 205 to move smoothly horizontally along slide rod 204. During the movement of T-shaped plate 205, paint storage tank 207 is moved synchronously through connecting rod 206. Paint storage tank 207 then drives hollow ring 209 to move slowly along the axial direction of pipe body 5 through round rod 208. As hollow ring 209 moves, nozzles 210 continuously spray paint onto the surface of pipe body 5, achieving full-length, no-dead-angle coverage of pipe body 5, avoiding blind spots caused by manual spraying. After the entire pipe body 5 is sprayed, extraction pump 21 is turned off. 1. Stop the paint supply, then control the motor 203 to run in reverse, driving the T-shaped plate 205 and the spraying assembly to return to the initial position. Start the electric telescopic rod 39 to retract, driving the arc-shaped clamp 34 to rise and release the clamp on the pipe body 5. The operator removes the sprayed pipe body 5 and places it in a ventilated place to dry. Finally, clean the paint residue on the nozzle 210 and pour out the excess paint in the collection mechanism. It can be filtered and reused to ensure that all parts of the device are clean and ready for the next maintenance operation. Through the above process, the device, with the help of the automatic movement of the mobile spraying device and the ring nozzle design, combined with the stable fixation of the clamping device, realizes the fully automatic and comprehensive spraying of fire pipelines. There is no need for manual hand-held spray guns, which effectively solves the problems of missed spraying and low efficiency of traditional manual spraying.
