Description

Technical Field

[0001] This utility model relates to the technical field of coiling high-pressure flexible water pipes, and in particular to an electric coiling device for high-pressure flexible water pipes. Background Technology

[0002] High-pressure flexible water pipes are widely used in emergency drainage scenarios such as underground coal mines, tunnel construction, and fire rescue due to their advantages of good flexibility, high pressure resistance, and rapid deployment. After use, the water pipes need to be quickly retrieved and neatly coiled for reuse or storage.

[0003] To reduce manual labor and improve efficiency, devices that automatically wind water pipes using motor-driven reels already exist. These devices use an electric drive system to rotate the reel, achieving automatic pipe winding. However, several practical problems remain in actual use: firstly, water pipes are flexible and long, easily slipping and swaying under gravity, resulting in uneven reels; secondly, the lack of auxiliary guiding and pressing structures leads to loose, bulky coils that occupy space; and thirdly, the pipe ends cannot pass through guide rollers, requiring manual start-stop operation for precise winding control when the pipe end approaches the guide rollers, which is inconvenient. These problems affect the practicality and reliability of automatic winding devices. Therefore, there is an urgent need to optimize the structure of existing technologies to enhance their stability and intelligence. Utility Model Content

[0004] In response to the technical problems of unstable operation, loose coiling, and the need for manual intervention in existing automatic winding devices, this utility model provides a high-pressure flexible water pipe electric winding device.

[0005] This utility model adopts the following technical solution: a high-pressure flexible water pipe electric coiling device, including a rectangular frame, rubber wheels at the four corners of the bottom of the frame, counterweights on both sides along the length of the frame, a drive assembly inside the frame, a coiling assembly above the frame, and guide assemblies at the ends of the frame. The drive assembly includes a housing fixed in the middle of the frame, a geared motor inside the housing, the output shaft of the geared motor pointing vertically upwards, and a coiling assembly including a rotating shaft connected to the output shaft of the geared motor. The transmission connection includes a rotating shaft with its upper end fixedly connected to the center of the reel. A ring is arranged around the outer perimeter of the reel. At least three roller frames are arranged above the machine frame corresponding to the ring. The included angle between adjacent roller frames with the center of the reel as the center is no greater than 120°. Roller support rings are installed on the roller frames. A vertical sliding assembly is arranged above the center of the reel. A reel frame is arranged on the vertical sliding assembly. The reel frame includes rectangular frames arranged at intervals. Two rectangular frames are connected by a connecting frame in the middle. The connecting frame is vertically slidably connected to the vertical sliding assembly.

[0006] Furthermore, the connecting frame includes two horizontal bars spaced apart in the middle of the rectangular frame and vertically connecting the connecting rods on both sides of the rectangular frame along its length. Vertical bars are symmetrically arranged at both ends of the horizontal bars on the same side of the upper and lower rectangular frames and connected to each other. Longitudinal bars are symmetrically arranged between the horizontal bars and / or vertical bars on the upper and / or lower sides.

[0007] Furthermore, the vertical sliding assembly includes a guide rod arranged in a rectangle around the center of the reel, with the crossbars and longitudinal bars of the connecting frame engaged in the guide rod to restrict circumferential rotation.

[0008] Furthermore, two roller frames are provided on each side of the machine frame along its length.

[0009] Furthermore, the roller has a groove in the middle to accommodate the bottom of the ring.

[0010] Furthermore, the diameter of the ring is smaller than the width of the machine frame.

[0011] Furthermore, the guiding assembly includes a flat roller bracket fixed above the end side of the machine frame, a horizontally arranged flat roller is installed on the flat roller bracket, and vertical anti-deviation roller support sleeves are symmetrically arranged on both sides of the length direction of the flat roller on the end side of the machine frame, with anti-deviation rollers rotatably connected in the anti-deviation roller support sleeves.

[0012] Furthermore, a sensor bracket is installed on the outer side of the anti-deviation idler roller on the end of the machine frame, and a metal proximity switch is installed on the sensor bracket.

[0013] The high-pressure flexible water pipe electric coiling device proposed in this utility model has the following beneficial effects:

[0014] 1. It can improve the stability and neatness of winding. The winding frame is composed of upper and lower rectangular frames, forming a stable spatial constraint structure to guide the water pipe in shape, making the winding more compact and orderly; the roller frame provides multi-point support for the outer ring of the winding, reducing shaking and swaying, and improving the stability of the winding and the smooth operation of the equipment.

[0015] 2. Improved ease of operation and adaptability: The reel and reel rack are separate structures, which facilitates quick replacement or transportation of reeled water hoses by forklift, improving on-site operation efficiency; the high-pressure flexible water hoses are stored on the reel rack for easy storage and use.

[0016] 3. It can realize intelligent monitoring and reduce manual intervention. The metal proximity switch detects the position and status of the water pipe in real time and automatically stops the machine when the water pipe head is detected, effectively preventing pipe jamming or equipment damage during the winding process.

[0027] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a high-pressure flexible water pipe electric reeling device.

[0028] like Figures 1-3 As shown, a high-pressure flexible water pipe electric coiling device includes a machine base assembly 1, a drive assembly 2, a coiling assembly 3, a guide assembly 4, and an electrical control assembly 5.

[0029] The machine assembly 1 includes a machine frame 1-1, rubber wheels 1-2, and a counterweight water tank 1-3. The machine frame 1-1 is a cuboid, welded from stainless steel, with a length of at least 200cm, a width of at least 110cm, and a net height of at least 40cm. Internal space is provided for installing the counterweight water tank 1-3 and the drive assembly 2. Rubber wheels 1-2 are installed at the four corners of the bottom of the machine frame 1-1. All four rubber wheels 1-2 are made of rubber, providing load-bearing capacity, wear resistance, omnidirectional and directional braking functions. The rubber wheels 1-2 are fixed to the lower part of the four corners of the bottom of the machine frame 1-1 with screws, facilitating flexible movement and fixation of the device. Counterweight water tanks 1-3 are installed on both sides of the machine frame 1-1 along its length to add counterweight to the machine assembly 1 and prevent tipping during operation. The counterweight water tanks 1-3 are made of PVC, with a single volume of approximately 250L. The two counterweight water tanks 1-3 are placed on the stainless steel frames on both sides inside the machine frame 1-1, allowing for easy disassembly. The counterweight water tanks 1-3 are equipped with dual outlets for both upper and lower water supply, and can be connected to various water pipes.

[0030] A drive assembly 2 is installed in the middle of the machine frame 1-1. The drive assembly 2 includes a housing 2-1 and a geared motor 2-2. The housing 2-1 is welded to the middle of the machine frame 1-1. The side panels of the housing 2-1 are fixed with screws to achieve both safety protection and easy disassembly for maintenance. The geared motor 2-2 is installed inside the housing 2-1. The geared motor 2-2 is fixed to the bottom plate of the housing 2-1 by foot mounting. The output shaft of the geared motor 2-2 faces vertically upward.

[0031] A coiling assembly 3 is installed above the machine frame 1-1. The coiling assembly 3 includes a rotating shaft 3-1, a coil 3-2, and a vertical sliding assembly. The output shaft of the reduction motor 2-2 is axially fixed to the rotating shaft 3-1 via a flat key. The coil 3-2 is circular and nested at the upper end of the rotating shaft 3-1. A circular ring 3-3 is provided around the outer circumference of the coil 3-2. Two roller frames 7 are provided on each side of the machine frame 1-1 along its length. Rollers 8 are mounted on the roller frames 7 to support the circular ring 3-3. Figure 4 As shown, the roller 8 has a groove in the middle to accommodate the bottom of the ring 3-3. The vertical sliding assembly is vertically positioned above the center of the reel 3-2. The vertical sliding assembly includes a guide rod 3-4 arranged rectangularly around the center of the reel 3-2, and a reel holder 6 is mounted on the vertical sliding assembly. Figure 5 and Figure 6As shown, the reel rack 6 includes rectangular frames 6-1 spaced apart vertically. The two rectangular frames 6-1 are connected by a connecting frame in the middle. The connecting frame includes two horizontal bars 6-2 spaced apart in the middle of the rectangular frames 6-1 and vertically connecting the connecting rods on both sides of the length direction of the rectangular frames 6-1. Vertical bars 6-3 are symmetrically arranged at both ends of the horizontal bars 6-2 on the same side of the upper and lower rectangular frames 6-1 and connected to each other. Vertical bars 6-4 are symmetrically arranged between the horizontal bars 6-2 on the lower side. The horizontal bars 6-2 and the vertical bars 6-4 are vertically slidably connected to the guide rods 3-4 and are engaged to restrict the circumferential rotation of the reel rack 6.

[0032] A guide assembly 4 is provided on one end of the machine frame 1-1, such as... Figure 7 and Figure 8 As shown, the guide assembly 4 includes a flat roller bracket 4-1, a flat roller 4-2, an anti-deviation roller support sleeve 4-3, and an anti-deviation roller 4-4. The flat roller bracket 4-1 is welded and fixed above the end side of the machine frame 1-1. The roller shafts at both ends of the flat roller 4-2 pass through the holes at both ends of the flat roller bracket 4-1 and are installed together. The flat roller 4-2 provides flat support for the high-pressure flexible water pipe and rotates radially with the flat roller 4-2.

[0033] On this end side of the machine frame 1-1, vertical anti-deviation roller support sleeves 4-3 are symmetrically arranged on both sides of the length direction of the planar roller 4-2. The anti-deviation roller support sleeves 4-3 are welded and fixed to the machine frame 1-1 as a whole. The anti-deviation roller 4-4 is fitted on the anti-deviation roller support sleeve 4-3 to restrict the high-pressure flexible water pipe to a controllable range during coiling and prevent deviation.

[0034] like Figure 9 As shown, the electrical control component 5 includes a remote control switch 5-1, a power cord 5-2, a power plug 5-3, a remote controller 5-4, and a metal proximity switch 5-5. The remote control switch 5-1 is an integrated module, fixed to one side of the machine frame 1-1 with screws. It has forward and reverse rotation surge protection, a voltage of 220V, a power of 5.5kW, and a remote control distance of 1.5m. The purpose is to prevent personnel from having close contact with the device during operation after the remote control switch 5-1 is activated, thus minimizing safety risks.

[0035] The power cord 5-2 is a cable consisting of a live wire, a neutral wire, and a ground wire. The output terminal of the remote control switch 5-1 is connected to the geared motor 2-2 via the power cord 5-2. The input terminal of the remote control switch 5-1 is connected to the power plug 5-3 via the power cord 5-2. The power plug 5-3 is 10A and 220V. The 220V voltage is more convenient for this device to meet the power needs of daily places.

[0036] The remote control 5-4 has an integrated module that operates at the same frequency as the remote control switch 5-1. The remote control 5-4 can control the remote within a certain range. The remote control 5-4 panel is equipped with a start button, a stop button, a forward rotation button, and a reverse rotation button.

[0037] Sensor brackets 9 are symmetrically installed on the outer side of the anti-deviation roller 4-4 at one end of the machine frame 1-1. Metal proximity switches 5-5 are mounted on these sensor brackets 9. The metal proximity switch 5-5 has an integrated module with the same frequency as the remote control switch 5-1. Inside the metal proximity switch 5-5 is a high-frequency oscillation coil. When the power is turned on, the coil generates a high-frequency magnetic field. When a metal object enters the range of the alternating magnetic field, eddy currents are generated within the metal, consuming magnetic field energy and changing the oscillation amplitude of the high-frequency oscillation circuit. The signal processing circuit detects this change in oscillation amplitude and converts it into an electrical signal. This signal changes the state of the electronic components inside the switch, thus disconnecting the output to indicate that a metal object has been detected.

[0038] In use, first, fix one end of the high-pressure flexible water pipe (traction end) to the connecting frame of the coiling frame 6 using the flat roller 4-2 and the anti-deviation roller 4-4. Connect the power supply and press the start switch on the remote control 5-4. The output shaft of the reduction motor 2-2 drives the coil 3-2 to rotate, pulling the traction end of the high-pressure flexible water pipe to coil at a uniform speed. During coiling, the anti-deviation roller 4-4 guides the coiling path of the water pipe and continuously squeezes and reshapes any trapped water, air, or deformed water pipe. This causes residual water and air in the water pipe to be continuously squeezed towards the other end (end) of the water pipe. Due to the height difference between the traction end and the end of the water pipe, the trapped water and air in the water pipe will continuously flow towards the outlet of the end of the water pipe and be expelled. At the same time, the water pipe is coiled neatly and flat, and its volume is correspondingly reduced. When the end connector of the high-pressure flexible water pipe is close to the magnetic field, because the connector is made of aluminum conductive material, eddy currents will be generated inside the aluminum metal under the action of the magnetic field. The generation of eddy currents will consume the energy of the magnetic field, causing the oscillation amplitude of the oscillation coil to decrease or even stop oscillating. The internal circuitry of the metal proximity switch 5-5 detects this change in oscillation amplitude, thereby determining the approach of the high-pressure flexible water pipe connector and outputting a corresponding signal to change the switch state from normally closed to open. Finally, a forklift is used to detach the coiled high-pressure flexible water pipe from the coil rack 6 from the reel 3-2 and transport it to the storage location by hoisting or forklift.

[0039] While maintaining the basic functions of automatic coiling, this utility model significantly improves coiling quality, safety performance and operating efficiency through structural and control optimization, and is suitable for efficient water pipe coiling operations in various complex working environments.
