The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0020] The first embodiment of this application is as follows:
[0021] Please see Figures 1 to 4 ,in Figure 1 This is a schematic diagram of the overall structure of a marine pneumatic winch. Figure 2 This is an overall front view of a marine pneumatic winch. Figure 3 This is a structural diagram of a compact component. Figure 4This is a schematic diagram of the locking ring's movement. This utility model provides a marine pneumatic winch: including a fixed base 101, a pneumatic motor 102, a control valve 103, a pneumatic directional valve 104, an air duct 105, and an airtight device. The airtight device includes a mounting ring 106, an anti-slip pad 107, a tightening assembly, and a mating assembly. The tightening assembly includes a locking ring 108 and a rubber ring 109. The locking ring 108 is provided with striped blocks 110. The mating assembly includes a left protective ring 111 and a right protective ring 112. The fixed base 101 is provided with a storage box 113. The aforementioned solution addresses the issue of air leakage during the use of this pneumatic winch, where the airtightness of the connection between the air pipe 105 and the pneumatic directional valve 104 is prone to occur, and the airtightness needs to be improved. It is understood that the aforementioned solution can be used to improve the airtightness between the air pipe 105 and the pneumatic directional valve 104 during the use of this pneumatic winch, thereby improving the performance. It can also be used to improve the airtightness between the air pipe 105 and the control valve 103.
[0022] In this specific embodiment, the pneumatic motor 102 and the control valve 103 are fixedly mounted on the fixed base 101. The pneumatic reversing valve 104 is located above the pneumatic motor 102. One end of the air pipe 105 is connected to the pneumatic reversing valve 104, and the other end of the air pipe 105 is connected to the control valve 103. The fixed base 101 is equipped with the pneumatic motor 102 and the control valve 103. The pneumatic reversing valve 104 is located above the pneumatic motor 102, and the air pipe 105 is located on the pneumatic reversing valve 104. The air pipe 105 is connected to an external air compression and delivery pipe. By starting the pneumatic motor 102, the winch is agitated. This method is clean and hygienic, has good explosion-proof performance, and is highly safe. All of the above are existing technologies.
[0023] The mounting ring 106 is fixedly connected to the pneumatic reversing valve 104 and located on one side of the pneumatic reversing valve 104. The anti-slip pad 107 is fixedly connected to the fixed base 101 and located on one side of the fixed base 101. The tight fitting assembly is disposed on the air duct 105. The mating assembly is disposed on the control valve 103. The mounting ring 106 is embedded on the right side of the pneumatic reversing valve 104 and has a groove. The lower surface of the fixed base 101 is provided with the anti-slip pad 107, which is made of soft rubber material to improve the stability of the fixed base 101. The tight fitting assembly is disposed on the left end of the outer surface of the air duct 105 and can be moved to the mounting ring 105. The mounting ring 106 is recessed to improve the airtightness between the ventilation pipe 105 and the pneumatic reversing valve 104. The control valve 103 is provided with the mating assembly. The mating assembly improves the airtightness between the ventilation pipe 105 and the control valve 103, thereby improving the performance of the pneumatic winch. During the use of this pneumatic winch, by setting the mounting ring 106 on the pneumatic reversing valve 104, the mating assembly on the ventilation pipe 105 is screwed into the mounting ring 106, thereby improving the airtightness between the ventilation pipe 105 and the pneumatic reversing valve 104. The mating assembly further improves the airtightness between the ventilation pipe 105 and the control valve 103, thus improving the performance.
[0024] Secondly, the locking ring 108 is threadedly connected to the ventilation pipe 105 and located on one side of the ventilation pipe 105; the rubber ring 109 is fixedly connected to the locking ring 108 and detachably connected to the mounting ring 106; the striped blocks 110 are arrayed on the outer surface of the locking ring 108, the locking ring 108 is located on the left side of the outer surface of the ventilation pipe 105, and the rubber ring 109 is provided on the outer surface of the locking ring 108. The rubber ring 109 is made of soft rubber material and has anti-slip and wear-resistant characteristics. After the ventilation pipe 105 is installed on the pneumatic reversing valve 104, the locking ring 108 is rotated, and the locking ring 108 is located on the... Driven by the thread of the ventilation pipe 105, the rubber ring 109 moves in the direction that facilitates the operation of the mounting ring 106 until the locking ring 108 enters the groove of the mounting ring 106. This causes the outer surface of the rubber ring 109 to fit tightly against the inner surface of the mounting ring 106, thereby improving the airtightness between the ventilation pipe 105 and the pneumatic reversing valve 104. The outer surface of the locking ring 108 is provided with an array of striped blocks 110. The striped blocks 110 increase the resistance between the operator and the locking ring 108 when the operator rotates the locking ring 108, making it easier to rotate the locking ring 108 and simplifying the operation.
[0025] Meanwhile, the left protective ring 111 is fixedly connected to the control valve 103 and detachably connected to the ventilation pipe 105; the right protective ring 112 is fixedly connected to the control valve 103 and detachably connected to the ventilation pipe 105. The ventilation pipe 105 passes through the control valve 103. The left protective ring 111 is located on the left side of the connection between the control valve 103 and the ventilation pipe 105. The left protective ring 111 fits tightly against the connection between the ventilation pipe 105 and the control valve 103. The right protective ring 112 is located on the right side of the connection between the control valve 103 and the ventilation pipe 105. The right protective ring 112 fits tightly against the connection between the ventilation pipe 105 and the control valve 103, thereby improving the airtightness between the ventilation pipe 105 and the control valve 103 and improving the performance of the pneumatic winch.
[0026] In addition, the storage box 113 is fixedly connected to the fixed base 101 and is located on one side of the fixed base 101. The storage box 113 is embedded in the front side of the upper surface of the fixed base 101. The storage box 113 has a large internal volume, which makes it convenient to place the tools needed by the operator, making the device more practical.
[0027] When using a marine pneumatic winch according to this embodiment, during the process of using this pneumatic winch, by setting the mounting ring 106 on the pneumatic reversing valve 104, the tight assembly set on the ventilation pipe 105 is screwed into the mounting ring 106, thereby improving the airtightness between the ventilation pipe 105 and the pneumatic reversing valve 104, and by setting the mating assembly, the airtightness between the ventilation pipe 105 and the control valve 103 is improved, thereby improving the performance.
