DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 5 , the utility model provides a technical solution: Example

[0024] The anti-inverting device for ship cables at a pier-type dock comprises a dock base 1, an anti-slip strip 2 is installed in the middle of the left end of the top of the dock base 1, a connecting structure is connected to the left side of the dock base 1 near the top, an abutting structure is connected to the left end of the connecting structure, and a buffer structure is connected to the middle of the right side of the abutting structure.

[0025] The connection structure includes a protection connection unit and a buffer unit. The buffer unit is arranged inside the protection connection unit. The protection connection unit includes a conical shield 101. A hanging ring 102 is arranged inside the right conical shield 101. The outer surface of the hanging ring 102 is connected to an outer cylinder 103. An inner rod 110 is connected to the left end of the outer cylinder 103. A hanging ring 2 111 is installed in the middle of the left end of the inner rod 110. A hanging ring 3 112 is arranged at the bottom of the hanging ring 2 111. The buffer unit includes a damping rod 104. An abutment plate 105 is fixedly installed on the left end of the damping rod 104. A fixed plate 106 is arranged on the left side of the abutment plate 105. A sliding rod 107 is connected to the middle of the fixed plate 106. A push plate 108 is fixedly installed on the right end of the sliding rod 107. A spring 109 is fixedly installed on the left side of the fixed plate 106.

[0026] The right end of the hanging ring 102 is fixedly connected to the left side of the dock base 1, the outer surface of the inner rod 110 is slidably connected to the inner wall of the outer tube 103, the fixing plate 106 is fixedly installed inside the outer tube 103, the outer surface of the sliding rod 107 is slidably connected to the inside of a circular hole opened in the middle of the right side of the fixing plate 106, the end of the spring 109 away from the fixing plate 106 is fixedly connected to the right end of the inner rod 110, and the right end of the damping rod 104 is fixedly connected to the middle of the right end inside the outer tube 103.

[0027] By setting the connection structure, utilizing the installation of the conical shield 101, and the sliding connection between the outer cylinder 103 and the inner rod 110, the phenomenon of the cable hanging upside down can be effectively avoided. At the same time, the sliding connection between the inner rod 110 and the outer cylinder 103, and the setting of the damping rod 104 and the spring 109 can achieve a buffering and adjustment effect, making it easy to use.

[0028] The hinge connection between the hanging ring 102 and the outer tube 103, as well as the conical shield 101 arranged outside the right end of the hanging ring 102 and the outer tube 103 can provide protection. At the same time, the conical shield 101 can shield and protect the hinge connection between the hanging ring 2 111 and the inner rod 110, thereby effectively preventing the cable from being hung upside down and avoiding damage to the cable. At the same time, this structure is simple and convenient to connect, which can effectively improve the efficiency of dock operations. At the same time, during use, when the inner rod 110 slides inside the outer tube 103, it pushes the sliding rod 107 and the pushing plate 108 to slide and move, and at the same time compresses the spring 109 to buffer the extrusion force. At the same time, the pushing plate 108 abuts against the abutment plate 105, and the setting of the damping rod 104 is used to buffer the impact force. Example

[0029] On the basis of the first embodiment, the abutment structure includes a buffer box 201, a second spring 202 is installed inside the buffer box 201, a guide rail 203 is fixedly installed in the middle of the inner surface of the buffer box 201, a slider 204 is slidably connected inside the guide rail 203, and a buffer pad 205 is connected to the left end of the slider 204 away from the guide rail 203. The inner wall of the buffer box 201 is slidably connected to the right end of the outer surface of the buffer pad 205, the outer surface of the slider 204 is slidably connected to the inner wall of the convex sliding groove of the guide rail 203, and the second spring 202 is abutted against the right side of the buffer pad 205 at one end away from the right end of the inside of the buffer box 201.

[0030] The buffer structure includes a rubber buffer cylinder 301, a connecting tube 302 is installed at the right end of the outer surface of the rubber buffer cylinder 301, a mounting cylinder 303 is connected to the end of the outer surface of the connecting tube 302 away from the rubber buffer cylinder 301, and an air bag 304 is installed inside the mounting cylinder 303. The right end of the rubber buffer cylinder 301 is fixedly connected to the middle of the left side of the dock base 1, the connecting tube 302 is connected to the inside of the rubber buffer cylinder 301 and the mounting cylinder 303, and the left end of the rubber buffer cylinder 301 abuts against the middle of the right side of the buffer box 201.

[0031] By setting up the abutment structure and the buffer structure, the slider 204 slides inside the guide rail 203, so that the buffer pad 205 squeezes the spring 202 to buffer the approaching ship. At the same time, the abutment of the rubber buffer tube 301 and the airbag 304 is used to buffer the force of the approaching collision of the ship and prevent the edge of the ship from being damaged.

[0032] When the ship docks and the edge of the ship collides with the buffer pad 205, the buffer pad 205 drives the slider 204 to slide on the inner wall of the convex slide groove opened in the guide rail 203, thereby causing the buffer pad 205 to squeeze the spring 202, and the deformation force of the spring 202 is used to buffer the impact force. At the same time, the buffer box 201 squeezes the rubber buffer tube 301, so that the air inside the rubber buffer tube 301 enters the airbag 304 through the connecting pipe 302 and the installation tube 303, so that the airbag 304 is filled, and the airbag 304 is used to abut against the right side of the buffer box 201, thereby increasing the buffering effect of the impact force of the buffer box 201.
