Description

Technical Field

[0001] This utility model relates to the technical field of shipboard ladder safety net fixing devices, and more specifically, to a fixing clamp for shipboard ladder safety nets. Background Technology

[0002] When using ship boarding ladder safety nets, they need to be fixed to the pier ledge. The current practice is to fix a bracket to the pier ledge with bolts, and the bracket is equipped with fixing rings. The ropes of the ship boarding ladder safety net are tied and fixed to the fixing rings. In the above structure, since the bracket is directly fixed to the pier ledge with bolts, it is impossible to move the bracket according to the fixing requirements of the ship boarding ladder safety net, which has the disadvantage of poor adaptability. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a fixing clamp for the safety net of the ship's boarding ladder, whose position relative to the pier protrusion can be adjusted according to the usage requirements, that is, it has the advantages of high flexibility and good adaptability.

[0004] This utility model provides a fixing clamp for a ship's boarding ladder safety net, including a first clamping member, a second clamping member, a clamp, and a screw rod. The first clamping member includes a clamping part and a guide rod part. The upper end of the clamping part is connected to the left end of the guide rod part to form an "L"-shaped structure. A fixing component is provided at the top of the left end of the guide rod part. The fixing component is used to tie and fix the ship's boarding ladder safety net to the fixing clamp. The upper end of the second clamping member is sleeved on the guide rod part located on the right side of the fixing component and can slide along the extension direction of the guide rod part. A blocking member is connected to the guide rod part located on the right side of the second clamping member. The blocking member is used to block the second clamping member to prevent the second clamping member from detaching from the guide rod part from left to right. The screw rod is transversely inserted into the lower end of the second clamping member and threadedly connected to the second clamping member. The clamp is rotatably connected to the left end of the screw rod, and a handle is connected to the right end of the screw rod. The clamping part and the clamp are used to clamp the two sides of the pier flange.

[0005] When in use, this utility model can clamp the fixing clamps at different positions on the pier flange according to the fixing requirements of the ship's boarding ladder safety net. Then, the ropes on the ship's boarding ladder safety net can be tied and fixed to the fixing components. That is, the position of this utility model relative to the pier flange can be adjusted according to the usage requirements, which has the advantages of high flexibility and good adaptability.

[0006] In one possible implementation, the fixing assembly includes two fixing rods arranged symmetrically on the left and right sides, forming an inverted "V" shape. The lower ends of both fixing rods are welded and fixed to the top of the left end of the guide rod. By using this fixing assembly, when the ropes of the ship's boarding ladder safety net are wrapped around the two fixing rods and tied to them, the inverted "V" shape of the two fixing rods effectively prevents the ropes of the ship's boarding ladder safety net from detaching from the two fixing rods, thus ensuring that the ship's boarding ladder safety net is reliably fixed to the fixing clamp.

[0007] In one possible implementation, the fixing assembly further includes a connecting rod located between the two fixing rods, with both ends of the connecting rod welded to the middle of the inner side of one of the fixing rods respectively. By adopting this structure, the connecting rod can connect and fix the two fixing rods, thereby further improving the fixing firmness of the fixing rods and avoiding the situation of detachment between the fixing rods and the guide rod.

[0008] In one possible implementation, the right side of the guide rod is provided with several insertion holes spaced apart from left to right. Each insertion hole penetrates the guide rod from front to back. The blocking element is a pin, which is inserted into one of the insertion holes from front to back. The pin is used to block the second clamping element to prevent the second clamping element from disengaging from the guide rod from left to right. With this structure, the pin can be engaged with the insertion holes at different positions, and when the second clamping element abuts against the pin, the distance between the clamping part and the chuck can be coarsely adjusted to achieve rapid adjustment of the distance between the clamping part and the chuck, thereby facilitating the clamping of the fixing fixture onto the wharf flange of different widths.

[0009] In one possible implementation, the handle is movably inserted into the right end of the lead screw along its radial direction. Both ends of the handle are welded and fixed with ball heads, the diameter of which is larger than the outer diameter of the handle. These ball heads abut against the outer wall of the lead screw to prevent the handle from detaching. With this structure, when the handle is operated and drives the lead screw to rotate, it can move flexibly along the radial direction of the lead screw, effectively preventing interference between the handle and the dock surface, thus providing convenience for the user. Furthermore, under the action of the ball heads, when the handle moves along the radial direction of the lead screw, the ball heads eventually abut against the outer wall of the lead screw to prevent the handle from detaching.

[0010] In one possible implementation, a first anti-slip rubber pad is attached and fixed to the inner wall of the clamping part, and a second anti-slip rubber pad is attached and fixed to the inner end of the chuck. By attaching and fixing the first anti-slip rubber pad to the inner wall of the clamping part and the second anti-slip rubber pad to the inner end of the chuck, the friction between the clamping part and the chuck and the chuck and the chuck can be increased after the clamping part and the chuck are clamped to both sides of the pier flange, thereby further achieving the purpose of anti-slip and improving the clamping firmness between the fixing fixture and the pier flange.

[0015] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] See Figure 1As shown in the embodiment of this application, a fixing clamp for a ship's boarding ladder safety net is disclosed, including a first clamping member 1, a second clamping member 2, a clamp 3, and a screw rod 4; the first clamping member 1 includes a clamping part 11 and a guide rod part 12, the upper end of the clamping part 11 is connected to the left end of the guide rod part 12 to form an "L"-shaped structure, and a fixing component is provided at the top of the left end of the guide rod part 12, which is used to tie and fix the ship's boarding ladder safety net to the fixing clamp; the second clamping member The upper end of 2 is sleeved on the guide rod portion 12 located on the right side of the fixing component and can slide along the extension direction of the guide rod portion 12. A blocking member is connected to the guide rod portion 12 located on the right side of the second clamping member 2. The blocking member is used to block the second clamping member 2 to prevent the second clamping member 2 from disengaging from the guide rod portion 12 from left to right. The lead screw 4 is transversely inserted into the lower end of the second clamping member 2 and threadedly connected to the second clamping member 2. The chuck 3 is rotatably connected to the left end of the lead screw 4. The right end of the lead screw 4 is connected to the handle 5. The clamping part 11 and the chuck 3 are used to clamp on both sides of the pier flange.

[0017] When using this utility model, first, the clamping part and the clamp are respectively located on both sides of the pier flange. Then, the screw is rotated by the handle to move the clamp towards the side closer to the clamping part. Finally, the clamping part and the clamp can cooperate to clamp on both sides of the pier flange, thus realizing the cooperation and clamping of the fixing fixture with the pier flange. Finally, the ropes on the safety net of the ship's boarding ladder are tied and fixed to the fixing component.

[0018] The fixing assembly includes two fixing rods 6 arranged symmetrically on the left and right sides, forming an inverted "V" shape. The lower ends of both fixing rods 6 are welded and fixed to the top of the left end of the guide rod part 12. By using this fixing assembly, when the ropes of the ship's boarding ladder safety net are wrapped around the two fixing rods and tied to them, the inverted "V" shape of the two fixing rods can effectively prevent the ropes of the ship's boarding ladder safety net from detaching from the two fixing rods, thus ensuring that the ship's boarding ladder safety net is reliably fixed to the fixing clamp.

[0019] The fixing assembly also includes a connecting rod 7, which is located between two fixing rods 6. The two ends of the connecting rod 7 are welded and fixed to the middle of the inner side of one of the fixing rods 6 respectively. With this structure, the connecting rod can connect and fix the two fixing rods, thereby further improving the fixing firmness of the fixing rods and avoiding the situation of detachment between the fixing rod and the guide rod.

[0020] The right side of the guide rod 12 is provided with several insertion holes 121 spaced apart from left to right. Each insertion hole 121 passes through the guide rod 12 from front to back. The blocking member is a pin 8, which is inserted into one of the insertion holes 121 from front to back. The pin 8 is used to block the second clamping member 2 to prevent the second clamping member 2 from disengaging from the guide rod 12 from left to right. With this structure, the pin can be engaged with the insertion holes at different positions, and when the second clamping member abuts against the pin, the distance between the clamping part and the chuck can be coarsely adjusted to achieve a quick adjustment of the distance between the clamping part and the chuck, thereby facilitating the clamping of the fixed fixture onto the pier flange of different widths.

[0021] The handle 5 is movably inserted into the right end of the lead screw 4 along the radial direction. Both ends of the handle 5 are welded and fixed with ball heads 51. The diameter of the ball head 51 is larger than the outer diameter of the handle 5. The ball head 51 is used to abut against the outer wall of the lead screw 4 to prevent the handle 5 from disengaging from the lead screw 4. With this structure, when the handle is operated and the lead screw is rotated, the handle can move flexibly along the radial direction of the lead screw, thereby effectively avoiding interference between the handle and the dock surface, which can bring convenience to the user. In addition, under the action of the ball head, when the handle moves along the radial direction of the lead screw, the ball head can finally abut against the outer wall of the lead screw to prevent the handle from disengaging from the lead screw.

[0022] A first anti-slip rubber pad 9 is attached and fixed to the inner wall of the clamping part 11, and a second anti-slip rubber pad 10 is attached and fixed to the inner end of the chuck 3. By attaching and fixing the first anti-slip rubber pad to the inner wall of the clamping part and the second anti-slip rubber pad to the inner end of the chuck, the friction between the clamping part and the chuck and the chuck and the chuck protrusion can be increased after the clamping part and the chuck are clamped to both sides of the pier protrusion, thereby further achieving the purpose of anti-slip and improving the clamping firmness between the fixing fixture and the pier protrusion.

[0023] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
