Abstract
Description
Technical Field
[0001] This application relates to the technical field of construction machinery, and in particular to a rope pressing structure. Background Art
[0002] Steel wire ropes are commonly used lifting tools and are widely used in engineering projects, such as offshore tugboats or lifting devices. Steel wire ropes are usually wound around the drum of a winch for subsequent retrieval and placement. When winding the steel wire rope, one end of the rope head is usually restricted to the drum in a fixed manner, and then the drum is rotated to neatly wind the steel wire rope around the drum.
[0003] However, in this way of fixing the rope head of the steel wire rope, when the steel wire rope is subjected to a large tensile force, such as when an offshore tugboat encounters strong winds and waves, or when a lifting device encounters a large tensile load, the additional tensile force generated by the steel wire rope far exceeds the rated load. Since the end of the steel wire rope is always fixed to the drum, the heavy object or the towed ship cannot be unhooked in time, which may cause equipment damage or even the overturning of the operating or rescue ship. Utility Model Content
[0004] In order to improve the situation of the steel wire rope when it is subjected to a large tensile load, this application provides a rope pressing structure.
[0005] This application provides a rope pressing structure, adopting the following technical solutions:
[0006] A rope pressing structure includes
[0007] A rope pressing plate and a drum. Side plates are provided at both ends of the drum. The outer diameter of the side plates is larger than the outer diameter of the drum. The rope pressing plate is arranged inside one of the side plates and is placed parallel to the side plate. A spiral steel wire rope groove is provided on the surface of the drum for placing the steel wire rope;
[0008] A fixing member. One end of the fixing member passes through the side plate and abuts against the side wall of the rope pressing plate. The fixing member is threadedly connected to the side plate. The rope pressing plate and the groove wall of the drum at the steel wire rope groove jointly clamp the rope head of the steel wire rope to fix the rope head of the steel wire rope.
[0009] By adopting the above technical solution, when installing the steel wire rope, the rope end at one end of the steel wire rope is placed in the groove at the end of the steel wire rope groove, and the pressing plate and the groove walls on both sides of the drum at the steel wire rope groove jointly press the rope end of the steel wire rope, thereby fixing the rope end. Subsequently, an external force is applied to tighten the fixing part, so that one end of the fixing part abuts against the side wall of the pressing plate, and the thrust generated by the screwing-in of the fixing part is used to push the pressing plate to further press the rope end of the steel wire rope, further fixing the position of the rope end. When the steel wire rope is subjected to a large tensile force, the large tensile force will pull the rope end of the steel wire rope. Since the instantaneous load of the large tensile force is very large, when the tensile load is greater than the maximum static friction force between the pressing plate and the groove wall on the steel wire rope, the steel wire rope can break free from the restraint of the pressing plate, and thus follow the heavy object to break free from the drum, avoiding causing greater damage to the equipment.
[0010] Optionally, a locking part is also sleeved on the fixing part. The locking part is located outside the side plate and is threadedly connected to the fixing part. After the fixing part abuts against the pressing plate, the side wall of the locking part abuts against the outer wall of the side plate.
[0011] By adopting the above technical solution, the locking part is threadedly connected to the fixing part. After the fixing part abuts against the pressing plate, the locking part is rotated so that the side wall of the locking part abuts against the outer wall of the side plate. The biting force between the screw teeth is used to limit the position of the fixing part, so that the fixing part always maintains the state of abutting against the pressing plate.
[0012] Optionally, the pressing plate is an arc plate, and the inner circle of the pressing plate fits the surface of the drum.
[0013] By adopting the above technical solution, the pressing plate is an arc plate, and the inner circle of the pressing plate is placed in contact with the surface of the drum. The arc-shaped pressing plate can effectively extend the effective contact area with the rope end of the steel wire rope, so that it can provide a greater contact friction force for the steel wire rope, and make the rope end of the steel wire rope be fixed on the drum more stably.
[0014] Optionally, a plurality of fixing parts are provided, and the plurality of fixing parts are spaced apart along the length direction of the pressing plate and all abut against the side wall of the pressing plate.
[0015] By adopting the above technical solution, a plurality of fixing parts are provided, and the plurality of fixing parts are spaced apart along the length direction of the pressing plate. More fixing parts abut against the pressing plate, which can provide a greater lateral pressure on the pressing plate, so that the pressing plate can have a greater lateral pressure on the rope end. Moreover, the fixing parts are spaced apart along the length direction of the pressing plate, making the abutting force of the fixing parts on the pressing plate more evenly distributed. At the same time, due to the presence of the pressing plate, the pressing plate can evenly apply the pressure of the fixing parts on the pressing plate to the rope end of the steel wire rope.
[0016] Optionally, one end of the fixing part abuts against the middle position in the width direction of the pressing plate, and the width of the pressing plate corresponds to the depth of the steel wire rope groove.
[0017] By adopting the above technical solution, one end of the fixing member abuts against the middle position in the width direction of the rope pressing plate, so that the rope pressing plate can always be parallel to the side plate, and thus can always press the steel wire rope in a posture perpendicular to the fixing member. At the same time, the width of the rope pressing plate corresponds to the depth of the steel wire rope groove, so that the rope pressing plate and the groove walls on both sides of the steel wire rope groove can correspond to each other, and the steel wire rope can be clamped more stably.
[0018] Optionally, a positioning member is also inserted through the side plate. One end of the positioning member is simultaneously inserted into the rope pressing plate and is threadedly connected to the rope pressing plate.
[0019] By adopting the above technical solution, one end of the positioning member is simultaneously inserted into the rope pressing plate and is threadedly connected to the rope pressing plate. The positioning member can play a role in positioning the rope pressing plate in the initial stage, thus facilitating the subsequent installation of the rope pressing plate.
[0020] Optionally, an abutting groove is formed in the side wall of the rope pressing plate close to the side plate. A buffer member is arranged in the rope pressing plate in the abutting groove. One end of the fixing member is inserted into the abutting groove and abuts against the buffer member.
[0021] By adopting the above technical solution, an abutting groove is formed in the side wall of the rope pressing plate close to the side plate. A buffer member is arranged in the rope pressing plate in the abutting groove. The formation of the abutting groove facilitates the insertion of one end of the fixing member for positioning. One end of the fixing member abuts against the buffer member. When a slight displacement of the rope pressing plate occurs due to the frictional force between the steel wire rope and the rope pressing plate, it will cause an impact on one end of the fixing member. The buffer member can absorb part of the impact through its own deformation, thereby reducing the damage to the fixing member.
[0022] Optionally, anti-slip textures are provided on the side wall of the rope pressing plate away from the buffer member.
[0023] By adopting the above technical solution, anti-slip textures are provided on the side wall of the rope pressing plate away from the buffer member. The anti-slip textures can increase the surface roughness of the rope pressing plate at the anti-slip grooves, thereby further providing greater frictional force for the fixation of the steel wire rope.
[0024] In summary, the present application has at least the following beneficial effects:
[0025] 1. By arranging a rope pressing plate inside the side plate and using the rope pressing plate and the groove walls of the drum at the steel wire rope groove to jointly clamp the end of the steel wire rope, the purpose of fixing the end of the steel wire rope is achieved. When the tensile force on the steel wire rope is greater than the maximum static frictional force provided by the rope pressing plate to the steel wire rope, the steel wire rope can smoothly break free from the restraint of the rope pressing plate;
[0026] 2. By adopting the method of using the fixing member to tightly press the rope pressing plate, the fixing member provides a lateral pressure to the rope pressing plate, and the rope pressing plate uniformly transmits the received pressure to the end of the rope, thereby effectively fixing the end of the rope;
[0027] 3. By adopting the method of passing the positioning member through the side plate and the rope pressing plate simultaneously, the positioning member can provide a positioning effect on the rope pressing plate, facilitating the subsequent installation of the rope pressing plate.

[0033] The following will Figures 1-4 further describe the present application in detail.
[0034] Embodiment 1 of the present application discloses a rope pressing structure. Referring to Figure 1 and Figure 2 , the rope pressing structure includes a rope pressing plate 1 and a reel 2. Side plates 21 are fixed at both ends of the reel 2. The outer diameter of the side plates 21 is greater than the outer diameter of the reel 2. The wire rope 3 is wound on the reel 2 between the two side plates 21. The side plates 21 can be used to limit the position of the wire rope 3, reducing the possibility of the wire rope 3 falling off. At the same time, a spiral wire rope groove 22 is formed on the surface of the reel 2. The wire rope groove 22 is used to place the wire rope 3. The rope pressing plate 1 is arranged at the inner side position of one of the side plates 21 and is placed parallel to the side plate 21. One end of the wire rope 3 is placed in the groove at the end of the wire rope groove 22. The groove wall of the reel 2 at the end of the wire rope groove 22 and the rope pressing plate 1 jointly clamp the end of the wire rope 3 to achieve the purpose of fixing the end of the wire rope 3.
[0035] To ensure that the rope pressing plate 1 always presses tightly against the end of the steel wire rope 3, a fixing member 4 is inserted through the side plate 21. The fixing member 4 can be a fastening bolt. One end of the fixing member 4 is inserted through the side plate 21 and presses tightly against the side wall of the rope pressing plate 1. At the same time, the fixing member 4 is threadedly connected to the side plate 21. When installing the steel wire rope 3, place the end of the steel wire rope 3 in the groove at the end of the steel wire rope groove 22. Use the rope pressing plate 1 and the groove walls on both sides of the drum 2 at the steel wire rope groove 22 to jointly press the end of the steel wire rope 3, thereby fixing the end of the rope. Subsequently, apply an external force to tighten the fixing member 4 so that one end of the fixing member 4 presses tightly against the side wall of the rope pressing plate 1. Use the thrust generated by the screwing of the fixing member 4 to push the rope pressing plate 1 to further press the end of the steel wire rope 3, further fixing the position of the end of the rope. When the steel wire rope 3 is subjected to a large tensile force, the large tensile force will pull the end of the steel wire rope 3. Since the instantaneous load of the large tensile force is very large, when the tensile load is greater than the maximum static friction force of the rope pressing plate 1 and the groove wall on the steel wire rope 3, the steel wire rope 3 can break free from the restraint of the rope pressing plate 1, and thus follow the heavy object to break free from the drum 2, avoiding causing greater damage to the equipment.
[0036] In Embodiment 1 of the present application, the rope pressing plate 1 is an arc plate, and the inner circle of the rope pressing plate 1 is placed in contact with the surface of the drum 2. The rope pressing plate 1 being an arc plate can effectively extend the effective contact area with the end of the steel wire rope 3, enabling it to provide a greater contact friction force for the steel wire rope 3, so that the end of the steel wire rope 3 can be fixed more stably on the drum 2.
[0037] The number of the fixing members 4 can be set to be multiple. The specific number can be increased or decreased according to the actual length of the rope pressing plate 1. In the embodiment of the present application, six fixing members 4 are provided. The six fixing members 4 are spaced along the length direction of the rope pressing plate 1 and are all in contact with the side wall of the rope pressing plate 1. More fixing members 4 pressing against the rope pressing plate 1 can provide a greater lateral pressure on the rope pressing plate 1, enabling the rope pressing plate 1 to have a greater lateral pressure on the end of the rope. And the fixing members 4 are spaced along the length direction of the rope pressing plate 1, making the tightening force of the fixing members 4 on the rope pressing plate 1 more evenly distributed. At the same time, due to the presence of the rope pressing plate 1, the rope pressing plate 1 can evenly act the pressure of the fixing members 4 on the rope pressing plate 1 on the end of the steel wire rope 3.
[0038] Refer to Figure 2 and Figure 3 , a locking member 41 is also sleeved on the fixing member 4. The locking member 41 can be a lock nut. The locking member 41 is located outside the side plate 21 and is threadedly connected to the fixing member 4. After the end of the rope is placed in place and the end of the rope is pressed tightly by the rope pressing plate 1, after rotating the fixing member 4 to press tightly against the rope pressing plate 1, rotate the locking member 41 so that the side wall of the locking member 41 presses tightly against the outer wall of the side plate 21. Use the biting force between the screw threads to limit the position of the fixing member 4, so that the fixing member 4 always maintains the state of pressing tightly against the rope pressing plate 1.
[0039] The fixing member 4 is passed through one end of the side plate 21 and abuts against the middle position in the width direction of the rope pressing plate 1, and the width of the rope pressing plate 1 corresponds to the depth of the wire rope groove 22. One end of the fixing member 4 abuts against the middle position in the width direction of the rope pressing plate 1, so that the rope pressing plate 1 can always be parallel to the side plate 21, and thus can always press the wire rope 3 in a posture perpendicular to the fixing member 4. At the same time, the width of the rope pressing plate 1 corresponds to the depth of the wire rope groove 22, so that the rope pressing plate 1 can correspond to the groove walls on both sides of the wire rope groove 22 and clamp the wire rope 3 more stably.
[0040] A positioning member 5 is also passed through the side plate 21. The positioning member 5 can be a positioning bolt. One end of the positioning member 5 is simultaneously passed through the rope pressing plate 1 and is threadedly connected to the rope pressing plate 1. The positioning member 5 can play a role in positioning the rope pressing plate 1 at the initial stage of the installation of the rope pressing plate 1, so as to facilitate the subsequent installation of the rope pressing plate 1.
[0041] The implementation principle of the wire rope pressing structure in Embodiment 1 of the present application is as follows: A rope pressing plate 1 is arranged inside the side plate 21, and the rope pressing plate 1 and the groove wall of the drum 2 at the wire rope groove 22 are used to jointly clamp the end of the wire rope 3, so as to achieve the purpose of fixing the end of the wire rope 3. When the tension received by the wire rope 3 is greater than the maximum static friction force provided by the rope pressing plate 1 to the wire rope 3, the wire rope 3 can smoothly break free from the restraint of the rope pressing plate 1. The fixing member 4 provides a lateral pressure to the rope pressing plate 1, and the rope pressing plate 1 evenly transfers the received pressure to the end of the rope, so as to effectively fix the end of the rope. The positioning member 5 is simultaneously passed through the side plate 21 and the rope pressing plate 1, so that the positioning member 5 can provide a positioning effect on the rope pressing plate 1 and facilitate the subsequent installation of the rope pressing plate 1.
[0042] Embodiment 2:
[0043] The difference between Embodiment 2 and Embodiment 1 is as follows: Refer to Figure 4 , a butting groove is formed in the side wall of the rope pressing plate 1 close to the side plate 21, and a buffer member 11 is embedded in the butting groove of the rope pressing plate 1. The buffer member 11 can be a rubber buffer pad with a certain elasticity. One end of the fixing member 4 is inserted into the butting groove and abuts against the buffer member 11. The formation of the butting groove facilitates the insertion of one end of the fixing member 4 for positioning. One end of the fixing member 4 abuts against the buffer member 11. When a slight displacement of the rope pressing plate 1 occurs due to the friction between the wire rope 3 and the rope pressing plate 1, it will cause an impact on one end of the fixing member 4. The buffer member 11 can absorb part of the impact through its own deformation, so as to reduce the damage to the fixing member 4.
[0044] Further, an anti-slip texture 12 is provided on the side wall of the rope pressing plate 1 away from the buffer member 11. The anti-slip texture 12 can increase the surface roughness of the rope pressing plate 1 at the anti-slip groove 11, thereby further providing a greater frictional force for the fixation of the steel wire rope 3. In other embodiments of the present application, the anti-slip texture 12 can also be an anti-slip pad, which can also provide a greater frictional force for the fixation of the steel wire rope 3.
[0045] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
