Description

Technical Field

[0001] The present invention relates to the field of high-pressure cleaning machines, and in particular to a supporting and shock-absorbing device for a high-pressure cleaning machine unit. Background Art

[0002] A high-pressure cleaner uses a high-pressure plunger pump to generate high-pressure water to wash surfaces. It removes dirt and washes it away, ultimately cleaning the surface. Because it uses high-pressure water jets to remove dirt, high-pressure cleaning is recognized worldwide as one of the most scientific, economical, and environmentally friendly cleaning methods. When used, the motor and pump inside a high-pressure cleaner rotate at high speed, generating vibrations that affect internal components. This not only creates loud noise but also shortens the lifespan of the equipment.

[0003] Existing high-pressure cleaning units generally use multiple sets of combined springs and rubber washers to reduce vibration, but the shock absorption effect is poor. In addition, the bottom of the high-pressure body, which is fixed to reduce vibration, directly fits the mounting base, making it easy for heat to accumulate at the bottom and difficult to dissipate, directly causing the high-pressure cleaning unit to malfunction due to the high working environment temperature.

[0004] Therefore, it is necessary to provide a new support and shock absorbing device for a high-pressure cleaning unit to solve the above technical problems. Summary of the Invention

[0012] Preferably, a double-outlet water distribution component is installed and connected on the lower end wall of the water tank, and the double-outlet water distribution component is connected to the two main pipes respectively through two water pipes. A groove is provided on the upper end surface of the disk body, and a surrounding water pipe is installed and connected in the groove. One end of the surrounding water pipe is provided with two interfaces, and the two interfaces are respectively connected to the two branch pipes through two first connecting pipes. The lower end of the annular seat is fixedly connected to an upper pipe, and a plurality of vertical pipes are provided on the upper pipe.

[0013] Preferably, the plurality of vertical tubes are arranged at equal intervals, a fan blade is provided on one side of the plurality of vertical tubes, and one end of the secondary sub-shaft is fixedly connected to the center of the fan blade.

[0014] Compared with the related art, the support and shock absorbing device for a high-pressure cleaning unit provided by the present invention has the following beneficial effects:

[0015] 1. The present invention drives the shift plate to move by the central plate. The side plates at both ends of the shift plate drive the two sliding rods, which are equivalent to the sliding of the two end walls of the horizontal pipe. The two sliding rods jointly drive the main piston to move inside the horizontal pipe. The negative pressure on both sides of the main piston changes alternately, so that the water in the water tank passes through the double-outlet water distribution piece and the liquid inlet valves in the two main pipes and enters the two ends of the horizontal pipe in sequence, and is then transported to the interior of the surrounding water pipe. The continuously transported water can effectively take away the heat generated at the bottom of the high-pressure cleaning unit, and achieve good heat dissipation while vibrating.

[0016] 2. The present invention causes the central vertical rod at its bottom to slide relative to the sliding opening in the middle of the annular seat by vibrating the disk body. The built-in spring in the central vertical rod causes the built-in rod to move downward. The lower end of the built-in rod drives the push bar to move downward, which in turn drives the eccentric shaft to rotate. The rotation of the eccentric shaft drives the main and auxiliary shafts to rotate relative to the two vertical plates. The rotation of the main and auxiliary shafts causes the center plate to move back and forth accordingly, so that the center plate can drive the shift plate to move accordingly.

[0017] 3. The present invention enables the multiple support rods to rotate relative to the multiple supporting rods while moving, so that the multiple supporting rods slide relative to the multiple fixed cylinders, and the multiple return springs are elastically deformed. The elastic force of the multiple return springs effectively buffers the vibration force. One end of the multiple supporting rods simultaneously drives the multiple small pistons to slide inside the multiple fixed cylinders, so that the negative pressure inside the multiple fixed cylinders changes accordingly. The change in air pressure inside the multiple fixed cylinders and the elastic force of the multiple return springs can be used to buffer the vibration force in a dual-effect manner, effectively reducing the vibration generated by the high-pressure cleaning unit during operation.

[0018] 4. The present invention refluxes the cooling water into the upper tube, then disperses it into multiple vertical tubes, and then collects it into the lower tube for reflux. The multiple vertical tubes are used to disperse the hot cooling water, making it convenient for further heat dissipation treatment.

[0019] 5. The present invention drives the fan blades to rotate simultaneously through one end of the auxiliary shaft, and utilizes the normal blowing of airflow to accelerate the dissipation of heat in multiple vertical pipes, thereby achieving efficient heat dissipation treatment of cooling water.

The lower end of the annular seat 3 is fixedly connected to two vertical plates 12, and the two vertical plates 12 are symmetrically arranged; an auxiliary mechanism, the auxiliary mechanism includes a cross tube 5, the cross tube 5 is fixedly connected to the vertical plate 12 at one end, and a sliding rod 51 is slidably connected to the tube wall at both ends of the cross tube 5. A main piston 52 is provided inside the cross tube 5, and the two sliding rods 51 are fixedly connected to the main piston 52 at the opposite ends. A shift plate 53 is provided above the cross tube 5, and both ends of the shift plate 53 are fixedly connected to side plates 531. The two side plates 531 are respectively fixedly connected to the other ends of the two sliding rods 51. A middle plate 54 is fixedly connected to the middle position of the shift plate 53, and suction and discharge components are provided at both ends of the cross tube 5.

[0031] In the specific implementation process, Figure 2 and Figure 3 As shown, the suction and discharge assembly includes a main pipe 55, one end of which is connected to the pipe wall of the horizontal pipe 5, and a branch pipe 56 is provided on the main pipe 55. A liquid inlet valve 57 is installed and connected inside the main pipe 55, and a liquid outlet valve 58 is installed and connected inside the branch pipe 56.

[0032] It should be noted that: the side plates 531 at both ends of the shift plate 53 drive the two sliding rods 51 to slide along the walls of the two ends of the cross tube 5, and the opposite ends of the two sliding rods 51 jointly drive the main piston 52 to move inside the cross tube 5. The negative pressure on both sides of the main piston 52 changes alternately, so that the water stored in the water tank 2 enters the two ends of the cross tube 5 in turn through the double-outlet water distribution component 8 and the liquid inlet valves 57 in the two main pipes 55, and then is output in turn through the liquid outlet valves 58 in the two branch pipes 56. The vibration force is used to ensure that the continuously delivered water can well take away the heat generated at the bottom end of the high-pressure cleaning unit.

[0033] refer to Figure 1 and Figure 4As shown, an eccentric shaft body 6 is provided between the two vertical plates 12, one end of the eccentric shaft body 6 is fixedly connected to the main sub-shaft 61, and the other end of the eccentric shaft body 6 is fixedly connected to the secondary sub-shaft 62. The main sub-shaft 61 is rotatably connected to the vertical plate 12 at one end, and the secondary sub-shaft 62 is rotatably connected to the vertical plate 12 at the other end. A sliding mouth is provided at the center position of the annular seat 3, and a central vertical rod 63 is slidably connected in the sliding mouth. The top of the central vertical rod 63 is fixedly connected to the lower end of the disk body 31. The interior of the central vertical rod 63 is provided with a sliding cavity. The sliding cavity is slidably connected to an internal rod 64, and one end of the internal rod 64 is provided with a convex piece. The internal rod 64 is sleeved with an internal spring 66. One end of the internal rod 64 is rotatably connected to a push bar 65 through a first pin shaft, and the other end of the push bar 65 is rotatably connected to the eccentric shaft body 6 through a second pin shaft. One end of the internal spring 66 is connected to the convex piece, and the other end of the internal spring 66 is connected to the cavity wall of the sliding cavity.

[0034] It should be noted that the vibration of the disk body 31 causes the central vertical rod 63 at its bottom end to slide relative to the sliding opening in the middle of the annular seat 3. The built-in spring 66 in the central vertical rod 63 causes the built-in rod 64 to move downward. The lower end of the built-in rod 64 drives the push bar 65 to move downward and simultaneously drives the eccentric shaft body 6 to rotate. The rotation of the eccentric shaft body 6 drives the main sub-shaft 61 and the auxiliary sub-shaft 62 to rotate relative to the two vertical plates 12. The rotation of the main sub-shaft 61 causes the center plate 54 to move back and forth accordingly, and the center plate 54 drives the shift plate 53 to move accordingly.

[0035] If the vibration intensity of the disk body 31 is different, when the built-in rod 64 moves to the lowermost end, the built-in rod 64 slides relative to the sliding cavity in the central vertical rod 63, causing the built-in spring 66 to undergo elastic deformation, so that the built-in rod 64 can be used in conjunction with the central vertical rod 63 to make it suitable for different vibration intensities and relative distances.

[0036] refer to Figure 1 and Figure 2 As shown, one end of the main shaft 61 is a reciprocating screw rod, and a corresponding threaded opening is provided on the middle plate 54 , and the middle plate 54 is threadedly connected to one end of the main shaft 61 .

[0037] It should be noted that the rotation of the main shaft 61 causes the center plate 54 to move back and forth, and the center plate 54 drives the shift plate 53 to move accordingly.

[0038] refer to Figure 1 and Figure 5As shown, the annular seat 3 is provided with a plurality of mounting grooves, and a fixed cylinder 7 is installed and connected in the plurality of mounting grooves. A push rod 71 is slidably connected to the cylinder wall of one end of the plurality of fixed cylinders 7, and one end of the plurality of push rods 71 ​​is rotatably connected to the support rod 72. The other ends of the plurality of support rods 72 are rotatably connected to the lower end of the disc body 31. The other ends of the plurality of push rods 71 ​​are fixedly connected to a small piston 74. The plurality of small pistons 74 are respectively arranged inside the plurality of fixed cylinders 7. Reset springs 75 are respectively sleeved on the plurality of push rods 71, and one end of the plurality of reset springs 75 is respectively connected to the plurality of small pistons 74, and the other ends of the plurality of reset springs 75 are respectively connected to the inner walls of the plurality of fixed cylinders 7.

[0039] It should be noted that the high-pressure pump group 4 generates vibrations when in operation, causing the disc 31 to drive the multiple support rods 72 to move and simultaneously rotate relative to the multiple support rods 71, causing the multiple support rods 71 ​​to slide relative to the wall of one end of the multiple fixed cylinders 7, and the multiple return springs 75 to elastically deform, so that the elastic force of the multiple return springs 75 effectively buffers the vibration force;

[0040] One end of the plurality of rods 71 ​​simultaneously drives the plurality of small pistons 74 to slide inside the plurality of fixed cylinders 7, so that the negative pressure inside the plurality of fixed cylinders 7 changes accordingly, and the air pressure inside the plurality of fixed cylinders 7 further prevents the movement of the plurality of small pistons 74;

[0041] The elastic force of the multiple return springs 75 and the air pressure inside the multiple fixed cylinders 7 can buffer the vibration force in a dual-effect manner, effectively reducing the vibration generated by the high-pressure cleaning unit during operation.

[0042] refer to Figure 5 and Figure 6 As shown, a limiting ring 73 is installed and connected to the cylinder wall of one end of each of the plurality of fixed cylinders 7 , and a plurality of push rods 71 ​​are slidably connected to the plurality of limiting rings 73 respectively.

[0043] It should be noted that the provision of multiple limiting rings 73 can further limit and reinforce the lateral movement of the multiple supporting rods 71, ensuring that the multiple supporting rods 71 ​​can move stably.

[0044] refer to Figure 1 and Figure 7As shown, a double-outlet water distribution component 8 is installed and connected to the lower end box wall of the water tank 2, and the double-outlet water distribution component 8 is connected to the two main pipes 55 through two water pipes respectively. A groove is provided on the upper end disk surface of the disk body 31, and a surrounding water pipe 81 is installed and connected in the groove. One end of the surrounding water pipe 81 is provided with two interfaces, and the two interfaces are respectively connected to the two branch pipes 56 through two first connecting pipes. The lower end of the annular seat 3 is fixedly connected to an upper pipe 82, and a plurality of vertical pipes 83 are provided on the upper pipe 82. The lower ends of the plurality of vertical pipes 83 are commonly connected to a lower pipe 84. The other end of the surrounding water pipe 81 is connected to the upper pipe 82 through a second connecting pipe, and the lower pipe 84 is connected to the water tank 2 through a third connecting pipe.

[0045] It should be noted that the water stored in the water tank 2 enters the two ends of the horizontal pipe 5 in sequence through the double-outlet water distribution component 8 and the liquid inlet valves 57 in the two main pipes 55, and is then output through the liquid outlet valves 58 in the two branch pipes 56 in sequence, so that the cooling water is transported to the interior of the surrounding water pipe 81. The continuously transported water is used to take away the heat generated at the bottom of the high-pressure cleaning unit, so that the heat can be dissipated well while vibrating.

[0046] refer to Figure 1 and Figure 8 As shown, a plurality of vertical tubes 83 are arranged at equal intervals, a fan blade 9 is provided on one side of the plurality of vertical tubes 83 , and one end of the auxiliary branch shaft 62 is fixedly connected to the center of the fan blade 9 .

[0047] It should be noted that one end of the auxiliary shaft 62 simultaneously drives the fan blades 9 to rotate, utilizing the airflow to accelerate the heat dissipation in the plurality of vertical pipes 83, thereby achieving efficient heat dissipation of the cooling water in a multi-effect manner.

[0048] The working principle of the support and shock-absorbing device for a high-pressure cleaning unit provided by the present invention is as follows: the high-pressure pump group 4 generates vibration when working, so that it drives the multiple support rods 72 to rotate relative to the multiple push rods 71 ​​while moving, so that the multiple push rods 71 ​​slide relative to the one end wall of the multiple fixed cylinders 7, and the multiple return springs 75 all undergo elastic deformation, so that the elastic force of the multiple return springs 75 can buffer the vibration force well. One end of the multiple push rods 71 ​​simultaneously drives the multiple small pistons 74 to slide inside the multiple fixed cylinders 7, so that the negative pressure inside the multiple fixed cylinders 7 changes accordingly, and the air pressure inside the multiple fixed cylinders 7 is used to further prevent the movement of the multiple small pistons 74. The elastic force of the multiple return springs 75 and the air pressure inside the multiple fixed cylinders 7 can be used to dual-effect buffer the vibration force, effectively reducing the vibration generated by the high-pressure cleaning unit during operation.

[0049] The vibration of the disk body 31 causes the central vertical rod 63 at its bottom end to slide relative to the sliding opening in the middle of the annular seat 3. The built-in spring 66 in the central vertical rod 63 causes the built-in rod 64 to move downward. The lower end of the built-in rod 64 drives the push bar 65 to move downward and at the same time drives the eccentric shaft body 6 to rotate. The rotation of the eccentric shaft body 6 drives the main sub-shaft 61 and the auxiliary sub-shaft 62 to rotate relative to the two vertical plates 12. The rotation of the main sub-shaft 61 causes the middle plate 54 to move back and forth. The middle plate 54 drives the shift plate 53 to move accordingly, and the side plates 531 at both ends of the shift plate 53 drive the two The sliding rods 51 are equivalent to the sliding of the tube walls at both ends of the transverse tube 5. The opposite ends of the two sliding rods 51 jointly drive the main piston 52 to move inside the transverse tube 5. The negative pressure on both sides of the main piston 52 changes alternately, so that the water stored in the water tank 2 enters the two ends of the transverse tube 5 in turn through the double-outlet water distribution component 8 and the liquid inlet valves 57 in the two main pipes 55, and then is output in turn through the liquid outlet valves 58 in the two branch pipes 56, so that the cooling water is transported to the inside of the surrounding water pipe 81, and the continuously transported water is used to take away the heat generated at the bottom of the high-pressure cleaning unit, so that the heat can be dissipated well while vibrating.

[0050] If the vibration intensity of the disk body 31 is different, when the built-in rod 64 moves to the lowermost end, the built-in rod 64 slides relative to the sliding cavity in the central vertical rod 63, causing the built-in spring 66 to undergo elastic deformation, so that the built-in rod 64 can be used in conjunction with the central vertical rod 63 to make it suitable for different vibration intensities.

[0051] The cooling water then flows back to the interior of the upper tube 82, is dispersedly transported to multiple vertical tubes 83, and then flows back to the lower tube 84. The multiple vertical tubes 83 are used to disperse the hot cooling water, making it convenient for further heat dissipation treatment to be performed subsequently.

[0052] One end of the auxiliary shaft 62 simultaneously drives the fan blades 9 to rotate, utilizing the airflow to accelerate the heat dissipation in the plurality of vertical pipes 83, thereby achieving efficient heat dissipation treatment of the cooling water in a multi-effect manner.
