Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cleaning tools, in particular to a water pipeline cleaning tool. Background Art

[0002] When liquid or fluid slag with solid particles is transported through a pipeline, there will be residual materials inside the pipeline, and the transportation is not clean, which will cause the residual materials to adhere to the pipeline. This will not only cause material waste for a long time, but also the accumulation of materials attached to the inside of the pipeline will affect the transportation effect. For this reason, it is necessary to design pipeline cleaning tools to clean the pipeline regularly.

[0003] Existing tools for brushing and cleaning the inner wall of a pipe by driving a motor to rotate at high speed have a driving shaft that is quite long for connecting the brush component and the motor in order to be suitable for the length of the pipe and to clean a longer pipe. This makes it difficult for the longer driving shaft and the brush component far away from the motor to keep the central axis centered when the impurities on the brush component are centrifugally cleaned, resulting in a large eccentric resonance, making it impossible or difficult for the hand to stably grasp and fix the motor and the entire tool. The entire tool may be thrown away by the eccentric resonance force, causing a safety accident. Utility Model Content

[0004] In view of this, the utility model provides a water pipe cleaning tool to solve the problem that when centrifugally cleaning impurities on the brush component, the longer drive shaft and the brush component far away from the motor are difficult to keep the central axis centered when rotating at high speed, which will produce a large eccentric resonance, making it impossible or difficult for the hand to stably grasp and fix the motor and the entire tool, causing safety accidents.

[0005] The technical solution proposed by the utility model is: a water pipeline cleaning tool, which specifically includes a driving motor, a hexagonal driving shaft and a brushing component, wherein the hexagonal driving shaft is installed at the center of the driving motor, and the front end of the hexagonal driving shaft is fixed with a brushing component;

[0006] It is characterized in that a shaft sleeve is rotatably installed at the center of the driving motor, the shaft sleeve is integrated and fixed together with the rotor, and the hexagonal driving shaft and the shaft sleeve are slidably fitted through the shaft sleeve; two plug-in positioning pieces are symmetrically and slidably installed on the front end protruding part of the shaft sleeve, and the plug-in positioning piece is a U-shaped structure, and two plug-in shafts are symmetrically welded on the horizontal part toward the center position of the shaft sleeve, and the head ends of the two plug-in shafts are plug-fitted with the hexagonal driving shaft; a slip ring is slidably sleeved on the head end part of the shaft sleeve, and two connecting rods are symmetrically and rotatably connected between the slip ring and the two plug-in positioning pieces; a limit ring is slidably sleeved on the driving motor through a spring push sliding sleeve, and under normal conditions, the limit ring and the rear side vertical support part of the plug-in positioning piece are sleeved and fitted to position the plug-in positioning piece against;

[0007] When the centrifugal cleaning is used, the brushing component slides backward along the shaft sleeve to approach the driving motor.

[0008] Furthermore,

[0009] A limiting disk is welded to the front end of the shaft sleeve, and the slip ring slides forward and comes into contact with the limiting disk.

[0010] Furthermore,

[0011] The head end of the connecting rod is rotatably connected to the top end of the front vertical support part of the plug-in positioning member, and a roller is rotatably installed on the top end of the rear vertical support part of the plug-in positioning member, and the roller rolls against the inner wall of the limiting ring.

[0012] Furthermore,

[0013] The rear half of the driving motor is symmetrically welded with two handle frames of U-shaped structures, and the brushing component is symmetrically welded with two sliding shafts supporting backwards, and the sliding shafts are pushed by springs to slide through and fit with the front vertical bending part of the handle frame.

[0014] Furthermore,

[0015] The brushing component is integrally formed by welding a circle of L-shaped support rods, and the outer side of the horizontal part of the L-shaped support rod is evenly and densely covered with stainless steel brush wires.

[0016] Furthermore,

[0017] Four positioning holes are arranged on the hexagonal driving shaft at intervals in the front and back directions.

[0018] Furthermore,

[0019] When the normal rotation cleaning is used, the four plug shafts of the two plug-in positioning parts are plugged into and matched with the two positioning holes on the front side. When the centrifugal cleaning is used, the four plug shafts are plugged into and matched with the two positioning holes on the rear side.

[0020] The utility model provides a water pipeline cleaning tool, which has the following beneficial effects:

[0021] When the utility model is used for centrifugal cleaning, the brush component slides backward along the shaft sleeve through the hexagonal driving shaft to approach the driving motor, which can reduce the distance between the brush component and the driving motor, reduce the rotational eccentric resonance effect caused by the brush component being away from the driving motor, and make the gripping and fixing force output by the hand sufficient to counteract the eccentric resonance force. Compared with the prior art, it can effectively reduce the probability of the tool as a whole falling out of the hand and flying away, which helps to improve the safety of the tool when used for centrifugal cleaning and reduce the occurrence of safety accidents.

[0022] In addition, two connecting rods, two plug-in positioning parts and a slip ring are connected together to form two crank slider mechanisms. Through this mechanism, only one slip ring needs to be slid forward and backward to push and drive the two plug-in positioning parts and the four plug-in shafts to synchronously push and slide toward each other, so as to loosen or tighten the hexagonal drive shaft at one time. Compared with traditional cleaning tools that use multiple threaded parts to position the hexagonal drive shaft, it can save the trouble of screwing multiple threaded parts in sequence for multiple turns during the loosening and tightening operation, and is easy to operate and use.

[0023] In addition, under normal circumstances, the limit ring and the rear vertical support part of the plug-in positioning piece are inserted into and cooperated to position the plug-in positioning piece, thereby preventing the plug-in positioning piece from rotating at high speed with the sleeve and being thrown outward by centrifugal force and separated from the hexagonal drive shaft, causing the positioning function of the hexagonal drive shaft to fail, which can indirectly ensure the normal and effective use of the tool.

[0040] Embodiment 1:

[0041] The utility model proposes a water pipeline cleaning tool, comprising a driving motor 1, a hexagonal driving shaft 2 and a brushing component 3. The hexagonal driving shaft 2 is installed at the center of the driving motor 1, and the brushing component 3 is fixed at the front end of the hexagonal driving shaft 2.

[0042] Among them, a shaft sleeve 104 is rotatably installed at the center of the driving motor 1, the shaft sleeve 104 is integrated and fixed together with the rotor, and the hexagonal driving shaft 2 is slidably matched with the shaft sleeve 104; two plug-in positioning pieces 4 are symmetrically slidably installed on the front end protruding part of the shaft sleeve 104, the plug-in positioning piece 4 is a U-shaped structure, and two plug-in shafts 401 are symmetrically welded on the horizontal part toward the center position of the shaft sleeve 104, and the head end parts of the two plug-in shafts 401 are plug-fitted with the hexagonal driving shaft 2, and the two plug-in shafts 401 can be plugged and positioned with the hexagonal driving shaft 2, so that the brushing component 3 is kept in a state of sliding forward away from the driving motor 1 to clean the pipeline and in a state of approaching the driving motor 1 to perform centrifugal cleaning on its body; a slip ring 105 is slidably sleeved on the head end part of the shaft sleeve 104, and two connecting rods 402 are symmetrically rotatably connected between the slip ring 105 and the two plug-in positioning pieces 4, and the two connecting rods 402, the two plug-in positioning pieces 4 and the slip ring 105 are connected together Two crank slider mechanisms are formed, through which only one slip ring 105 needs to be slid forward and backward to push and drive the two plug-in positioning members 4 and the four plug-in shafts 401 to synchronously push and slide toward each other, so that the hexagonal drive shaft 2 can be loosened or tightened at one time. Compared with the traditional cleaning tool that uses multiple threaded members to position the hexagonal drive shaft 2, it can save the trouble of screwing multiple threaded members in turn for multiple turns during the loosening and tightening operation, and is easy to operate and use; the limit ring 102 is pushed and slidably mounted on the drive motor 1 through the spring, and under normal circumstances, the limit ring 102 and the rear side vertical support part of the plug-in positioning member 4 are inserted and matched to position the plug-in positioning member 4 against each other, so as to prevent the plug-in positioning member 4 from rotating at a high speed with the shaft sleeve 104, being thrown outward by the centrifugal force and separated from the hexagonal drive shaft 2, causing the positioning function of the hexagonal drive shaft 2 to fail, which can indirectly ensure the normal and effective use of the tool, and when loosening and removing the plug-in positioning member 4, the limit ring 102 is slid backward and pulled out from it;

[0043] When used for centrifugal cleaning, the brush component 3 slides backward along the shaft sleeve 104 through the hexagonal drive shaft 2 to approach the drive motor 1, which can reduce the distance between the brush component 3 and the drive motor 1, and reduce the rotational eccentric resonance effect caused by the brush component 3 being away from the drive motor 1, so that the gripping and fixing force output by the hand is sufficient to counteract the eccentric resonance force. Compared with the existing technology, it can effectively reduce the probability of the tool falling out of the hand and flying away, which helps to improve the safety of the tool when used for centrifugal cleaning and reduce the occurrence of safety accidents.

[0044] Preferably,

[0045] A limit plate is welded to the front end of the shaft sleeve 104, and the slip ring 105 slides forward and comes into contact with the limit plate.

[0046] Preferably,

[0047] The head end of the connecting rod 402 is rotatably connected to the top end of the front vertical support part of the plug-in positioning member 4, and a roller is rotatably installed on the top end of the rear vertical support part of the plug-in positioning member 4. The roller rolls against the inner wall of the limit ring 102, and the roller can reduce the relative wear between the plug-in positioning member 4 and the limit ring 102.

[0048] Preferably,

[0049] Two handle frames 101 of U-shaped structure are symmetrically welded on the rear half of the driving motor 1, and two sliding shafts 103 supporting backwards are symmetrically welded on the brushing component 3. The sliding shafts 103 are pushed by springs to slide through the front vertical bending part of the handle frame 101.

[0050] Preferably,

[0051] The brushing component 3 is integrally formed by welding a circle of L-shaped support rods, and the outer side of the horizontal part of the L-shaped support rod is evenly and densely covered with stainless steel brush wires.

[0052] Based on the first embodiment, the second embodiment:

[0053] Four short positioning sleeves 1041 are symmetrically welded on the circumferential outer wall of the shaft sleeve 104 , and the insertion shaft 401 penetrates and slides with the short positioning sleeves 1041 .

[0054] Preferably,

[0055] Four positioning holes are formed on the hexagonal driving shaft 2 at intervals in the front and rear directions.

[0056] Preferably,

[0057] When used for normal rotation cleaning, the four plug-in shafts 401 of the two plug-in positioning members 4 are plugged into and matched with the two positioning holes at the front side. When used for centrifugal cleaning, the four plug-in shafts 401 are plugged into and matched with the two positioning holes at the rear side.

[0058] Working principle: When used for pipeline cleaning, the brush wiping component 3 is placed in the forward sliding position and slidably plugged into the pipeline. The driving motor 1 can rotate to drive the brush wiping component 3 to rotate at a high speed to perform sliding cleaning of dirt and impurities on the inner wall of the pipeline;

[0059] When the brushing component 3 is used for centrifugal cleaning, the brushing component 3 is slid backward along the shaft sleeve 104 through the hexagonal driving shaft 2 to approach the driving motor 1. The brushing component 3 is close to the driving motor 1, which can reduce the distance between the brushing component 3 and the driving motor 1, reduce the rotational eccentric resonance effect caused by the brushing component 3 being away from the driving motor 1, and make the grasping and fixing force output by the hand sufficient to counteract the eccentric resonance force, effectively reducing the probability of the tool falling out of the hand as a whole;

[0060] The head end parts of the two plug-in shafts 401 are plugged into and matched with the hexagonal drive shaft 2. The two plug-in shafts 401 can be plugged into and position the hexagonal drive shaft 2, so that the brushing component 3 remains in a state of sliding forward away from the drive motor 1 to clean the pipeline and in a state of sliding close to the drive motor 1 to perform centrifugal cleaning on its body. The two connecting rods 402, the two plug-in positioning members 4 and the slip ring 105 are connected together to form two crank slider mechanisms. Through this mechanism, only one slip ring 105 needs to slide forward and backward to push and drive the two plug-in positioning members 4 and the four plug-in shafts 401 to slide toward each other synchronously, so as to tighten and loosen the hexagonal drive shaft 2 at one time. Under normal circumstances, the limit ring 102 is inserted and matched with the rear side vertical support part of the plug-in positioning member 4 to abut and position the plug-in positioning member 4, so as to avoid the plug-in positioning member 4 rotating at high speed with the shaft sleeve 104, being thrown outward by the centrifugal force and separated from the hexagonal drive shaft 2, causing the positioning function of the hexagonal drive shaft 2 to fail.
