Description

Technical Field

[0001] The present invention relates to the technical field of cable pulling, and specifically to a labor-saving tooling for cable pulling. Background Art

[0002] In ship repair projects, the use of cables is essential. The diameter of the cables used in ship repair is generally about 50 mm. When the ship is docked at the pier, it is necessary to connect the shore power to the ship. At this time, the cable needs to be pulled from the pier across the bulwark to a designated position on the single-ship deck;

[0003] In the past, the process of pulling cables was relatively laborious for workers and had low efficiency. To reduce the work burden of workers and improve work efficiency, after on-site investigation and discussion, this labor-saving tooling for cable pulling was designed. Summary of the Invention

[0004] The purpose of the present invention is to provide a labor-saving tooling for cable pulling to solve the problems that the process of pulling cables in the past was relatively laborious for workers and had low efficiency.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A labor-saving tooling for cable pulling, including two vertical plates. One end of the two vertical plates is provided with a horizontal plate, and the other end of the two vertical plates is provided with a rotating shaft. A guiding roller is rotatably sleeved on the rotating shaft. At corresponding positions on the front surfaces of the two vertical plates, U-shaped hanging brackets for hanging on the ship's bulwark are provided;

[0006] A strip-shaped groove is penetrated on the surface of the vertical plate. A lead screw is rotatably installed in the strip-shaped groove. A nut sleeve is threadedly sleeved on the lead screw. The U-shaped hanging bracket is fixedly connected to the nut sleeve. A driven sector gear is sleeved at the end of the lead screw;

[0007] A notch penetrating the strip-shaped groove is opened at the end of the inner side of the vertical plate. A shaft rod is rotatably installed at one end of the two vertical plates close to the horizontal plate. Both ends of the shaft rod penetrate the notch, and driving sector gears meshing with the driven sector gear are fixedly installed at both ends of the shaft rod.

[0008] Wherein, an annular groove for restricting the cable is opened on the surface of the guiding roller.

[0009] Wherein, the guiding roller adopts a nylon roller.

[0010] Wherein, the U-shaped hanging bracket includes a cross bar, a short rod provided at one end of the cross bar, and a long rod provided at the other end of the cross bar. The long rod part of the U-shaped hanging bracket is fixed on the vertical plate.

[0011] Wherein, the short rod and the long rod are arranged in parallel, and both the short rod and the long rod are perpendicular to the cross bar.

[0012] Among them, clamping rods are symmetrically and rotatably installed inside the U-shaped hanger, and a telescopic spring is arranged between the free ends of the clamping rods and the inner wall of the U-shaped hanger.

[0013] Among them, hinge seats matching the clamping rods are symmetrically and fixedly installed on the inner wall of the U-shaped hanger, and one end of the clamping rod is rotatably connected to the U-shaped hanger through the hinge seat.

[0014] Among them, a connecting rod is fixedly connected between the two U-shaped hangers.

[0015] Among them, a grip ring is sleeved on the middle part of the shaft rod. The grip ring is made of a rubber sleeve, and protrusions for anti-slip are evenly arranged on the surface of the grip ring.

[0016] Among them, support plates are symmetrically and fixedly installed on the cross plate, and a shaft sleeve matching the shaft rod is fixedly installed at the end of the support plate. The shaft rod penetrates through the axis of the shaft sleeve, and the shaft rod is rotatably connected to the shaft sleeve.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. The present invention suspends the tooling on the ship's side wall through the U-shaped hanger, and then winds the cable to be pulled around the guide roller. During the process of pulling the cable, by driving the guide roller to rotate, the pulling force of the cable is reduced, the workload of workers is reduced, the work efficiency is improved, the work intensity is significantly improved, and the safety risk caused by the fatigue operation of workers is reduced;

[0019] 2. The present invention can drive the driving sector gear to rotate through the shaft rod, and then drive the lead screw to rotate in the strip groove through the cooperation of the driving sector gear and the driven sector gear. During the rotation of the lead screw, the nut sleeve moves along the strip groove, and at the same time, the nut sleeve drives the U-shaped hanger to move along the lead screw, so as to adjust the position of the U-shaped hanger on the vertical plate, and thus adjust the height of the guide roller. Since the pulling height of the cable is different, by adjusting the position of the U-shaped hanger on the vertical plate, the height of the guide roller can be changed, which is convenient for pulling the cable at different heights.

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0029] Please refer to Figure 1-7 , the present invention provides a technical solution: a cable pulling labor-saving tooling, including two vertical plates 10, one end of the two vertical plates 10 is provided with a horizontal plate 11, and the other end of the two vertical plates 10 is provided with a rotating shaft 12. The two vertical plates 10 are assembled together through the horizontal plate 11, and a U-shaped frame is formed by the combination of the horizontal plate 11 and the two vertical plates 10, and the rotating shaft 12 is fixedly installed at the open end of the U-shaped frame.

[0030] A guide roller 20 is rotatably sleeved on the rotating shaft 12, and U-shaped hangers 30 for hanging on the ship's side wall are provided at corresponding positions on the front surfaces of the two vertical plates 10. During use, the tooling is vertically hung on the ship's side wall through the U-shaped hanger 30, and then the cable to be pulled is wound around the guide roller 20. During the process of pulling the cable, by driving the guide roller 20 to rotate, the pulling force of the cable is reduced, the workload of the workers is reduced, the work efficiency is improved, the work intensity is significantly improved, and the safety risk caused by the workers' fatigue operation is reduced.

[0031] Among them, a strip-shaped groove 13 is penetrated on the surface of the vertical plate 10, a lead screw 40 is rotatably installed in the strip-shaped groove 13, a nut sleeve 41 is threadedly sleeved on the lead screw 40, the U-shaped hanger 30 is fixedly connected to the nut sleeve 41, a driven sector gear 42 is sleeved at the end of the lead screw 40. When the lead screw 40 is driven to rotate clockwise, the nut sleeve 41 moves to the left as the lead screw 40 rotates. When the lead screw 40 is driven to rotate counterclockwise, the nut sleeve 41 moves to the right as the lead screw 40 rotates;

[0032] A notch 14 penetrating through the strip-shaped groove 13 is formed at the inner end of the vertical plate 10. At one end of the two vertical plates 10 close to the horizontal plate 11, a shaft rod 50 is rotatably installed. Both ends of the shaft rod 50 penetrate through the notch 14, and driving sector gears 51 meshing with the driven sector gears 42 are fixedly installed at both ends of the shaft rod 50.

[0033] When it is necessary to adjust the position of the U-shaped hanger 30 on the vertical plate 10, the driving sector gear 51 can be driven to rotate through the shaft rod 50, and then the lead screw 40 is driven to rotate in the strip-shaped groove 13 through the cooperation of the driving sector gear 51 and the driven sector gear 42. During the rotation of the lead screw 40, the nut sleeve 41 moves along the strip-shaped groove 13, and at the same time, the nut sleeve 41 drives the U-shaped hanger 30 to move along the lead screw 40, so as to adjust the position of the U-shaped hanger 30 on the vertical plate 10, thereby adjusting the height of the guide roller 20. Since the pulling heights of the cables are different, by adjusting the position of the U-shaped hanger 30 on the vertical plate 10, the height of the guide roller 20 can be changed, which is convenient for pulling the cables at different heights.

[0034] Wherein, an annular groove 21 for restricting the cable is formed on the surface of the guide roller 20. When the cable to be pulled is wound around the guide roller 20, the cable is wound around the annular groove 21, and the cable is limited by the annular groove 21 to prevent the cable from falling off the guide roller 20 during the process of pulling the cable.

[0035] Wherein, the guide roller 20 is made of a nylon roller, which not only reduces the total weight but also reduces the problem of jamming due to rust during use.

[0036] Wherein, the U-shaped hanger 30 includes a cross bar, a short rod arranged at one end of the cross bar, and a long rod arranged at the other end of the cross bar. The long rod part of the U-shaped hanger 30 is fixed on the vertical plate 10. The short rod and the long rod are arranged in parallel, and both the short rod and the long rod are perpendicular to the cross bar. The U-shaped hanger 30 is installed on the vertical plate 10 through the long rod, and the short rod part is a free end. It is convenient to hang the U-shaped hanger 30 on the ship's gunwale through the short rod part.

[0037] Among them, in order to prevent the U-shaped hanger 30 from detaching after being hung on the ship's bulwark, clamping rods 32 are symmetrically and rotatably installed inside the U-shaped hanger 30. A telescopic spring 33 is provided between the free ends of the clamping rods 32 and the inner wall of the U-shaped hanger 30. Hinge seats 31 that cooperate with the clamping rods 32 are symmetrically and fixedly installed on the inner wall of the U-shaped hanger 30. One end of the clamping rod 32 is rotatably connected to the U-shaped hanger 30 through the hinge seat 31; when this tooling needs to be used, the opening of the U-shaped hanger 30 is sleeved on the ship's bulwark, and then the ship's bulwark will contact the clamping rod 32 and exert extrusion on the clamping rod 32, causing one end of the clamping rod 32 to rotate around the hinge seat 31. At the same time, the free ends of the clamping rods 32 expand to both sides, and the free ends of the clamping rods 32 exert extrusion on the telescopic spring 33. Then the ship's bulwark is clamped between the two clamping rods 32 to prevent the tooling from falling off the ship's bulwark.

[0038] Among them, in order to ensure the synchronous movement of the two U-shaped hangers 30, a connecting rod 34 is fixedly connected between the two U-shaped hangers 30. By connecting the two U-shaped hangers 30 through the connecting rod 34, not only can the synchronous movement of the two U-shaped hangers 30 be ensured, but also the position of the U-shaped hanger 30 can be restricted. When the lead screw 40 rotates, the nut sleeve 41 and the U-shaped hanger 30 can be prevented from rotating synchronously with the lead screw 40.

[0039] Among them, in order to facilitate the rotation of the drive shaft rod 50, a grip ring 52 is sleeved on the middle part of the shaft rod 50. The user can drive the shaft rod 50 to rotate through the grip ring 52, thereby driving the rotation of the driving sector gear 51;

[0040] When the user drives the shaft rod 50 to rotate, in order to prevent the grip ring 52 from wearing the user's hand, the grip ring 52 is made of a rubber sleeve, which plays a role in protecting the user's hand;

[0041] When the user holds the grip ring 52 and rotates the shaft rod 50, in order to prevent the user's hand from sliding relative to the grip ring 52, anti-slip protrusions are evenly provided on the surface of the grip ring 52, increasing the friction between the user's hand and the grip ring 52.

[0042] Among them, support plates are symmetrically and fixedly installed on the cross plate 11. The end parts of the support plates are fixedly installed with bushings 53 that cooperate with the shaft rod 50. The shaft rod 50 penetrates through the axis of the bushing 53, and the shaft rod 50 is rotatably connected to the bushing 53. By supporting the bushing 53 through the support plates, the axis of the bushing 53 and the axis of the shaft rod 50 are located on the same straight line. In this way, through the cooperation of the bushing 53 and the shaft rod 50, the shaft rod 50 can be rotatably installed between the two vertical plates 10.

[0043] Working principle: When in use, put the opening of the U-shaped hanger 30 on the ship's bulwark. Then the ship's bulwark will contact the clamping rod 33 and exert extrusion on the clamping rod 33, causing one end of the clamping rod 33 to rotate around the hinge seat 32. At the same time, the free ends of the clamping rod 33 expand to both sides, and the free ends of the clamping rod 33 exert extrusion on the telescopic spring 34. Then the ship's bulwark is stuck between the two clamping rods 33, thus hanging this tooling on the ship's bulwark. Then bypass the cable to be pulled around the guide roller 20. During the process of pulling the cable, by driving the guide roller 20 to rotate, the pulling resistance of the cable is reduced, the workload of workers is reduced, the work efficiency is improved, the work intensity is significantly improved, and the safety risk caused by workers' fatigued operation is reduced;

[0044] When it is necessary to adjust the pulling height of the cable upward, drive the shaft rod 50 to rotate through the grip ring 52. Then the shaft rod 50 drives the active sector gears 51 at both ends to rotate. At the same time, through the cooperation of the active sector gear 51 and the driven sector gear 42, drive the lead screw 40 to rotate in the strip-shaped groove 13. During the rotation of the lead screw 40, the nut sleeve 41 moves along the strip-shaped groove 13, and at the same time the nut sleeve 41 drives the U-shaped hanger 30 to move along the lead screw 40, thereby adjusting the position of the U-shaped hanger 30 on the vertical plate 10, and thus adjusting the height of the guide roller 20. By adjusting the position of the U-shaped hanger 30 on the vertical plate 10, the height of the guide roller 20 can be changed, which is convenient for pulling cables at different heights.

[0045] Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
