Example (b):
a rope pulling device comprises a transverse pipe 1, a pull rod 2, a tooth-shaped plate 12, a rotating block, a fixed block 9 and a movable block; the central position of the transverse pipe 1 is fixedly connected with the left end of the pull rod 2; the middle part of the pull rod 2 is provided with the movable block; the movable block comprises a fixed frame 3, a spring 4, a push rod 5 and a first rope pulling block 6; the fixed frame 3 is fixedly connected with the pull rod 2; the spring 4 is arranged in the fixed frame 3; the left end of the push rod 5 is fixedly connected with the right end of the spring 4, and the right end of the push rod 5 is fixedly connected with the side surface of the first rope pulling block 6; the right side of the first rope pulling block 6 is provided with a fixed block 9; the fixed block 9 is fixedly connected with the pull rod 2; one end of the fixed block 9 is a rotating block; the rotating block comprises a roller 10, a rotating rod 8 and a second rope pulling block 7; the roller 10 is rotatably connected with the pull rod 2; the left end of the rotating rod 8 is fixedly connected with the roller 10, and the right end of the rotating rod 8 is fixedly connected with the second rope pulling block 7; the right end of the pull rod 2 is fixedly connected with the bottom block 13; the upper end of the bottom block 13 is fixedly connected with the lower ends of the plurality of tooth-shaped plates 12.
Rubber layers are arranged on the surfaces of the fixing block 9, the first rope pulling block 6 and the second rope pulling block 7. The friction resistance to the rope is increased, and the rope is guaranteed not to slip when being drawn.
The rotating rod 8 is an arc-shaped rod. The second rope pulling block 7 can not be pushed against the first rope pulling block 6 too much when moving downwards, and can smoothly enter and exit.
The number of the tooth-shaped plates 12 is 4 and the tooth-shaped plates are sequentially distributed on the upper end of the bottom block 13; the two tooth-shaped plates 12 close to the two ends of the bottom block 13 are arranged oppositely to one side with the tooth patterns; the two tooth-shaped plates 13 positioned in the middle of the bottom block 13 are arranged back to back with the side with the tooth patterns. The two opposite tooth lines can better increase the resistance to the rope and ensure that the rope cannot slip.
The two tooth-shaped plates 12 close to the two ends of the bottom block 13 are all obliquely arranged and are all inclined 5-10 degrees to the tooth-shaped plate far away from the middle of the bottom block. The inclined tooth-shaped plates 12 cause the openings of the two tooth-shaped plates facing each other to be smaller as the positions of the two tooth-shaped plates are closer to the bottom block 13, and the rope moves towards the direction close to the bottom block when the rope is drawn, so that the resistance of the tooth-shaped plates to the rope is further increased. So that the rope puller does not slip when pulling the rope.
The outer surface of the transverse pipe 1 is provided with a silicone rubber layer. The silicon rubber layer increases the friction force between the hand and the transverse pipe, so that the hand is pulled more tightly and is not easy to be abraded and foamed.
The working principle of the embodiment is as follows:
when the rope pulling device is used, a rope is wound on the tooth-shaped plate and the bottom block with two opposite tooth grains in one rotating direction, then the rope passes through the first rope pulling block 6 and the fixed block 9 from the upper part, but the rope is positioned below the second rope pulling block 7, the second rope pulling block 7 is pushed downwards, the second rope pulling block 7 presses the rope on the fixed block 9 and the first rope pulling block 6, the first rope pulling block 6 is pushed leftwards to compress the spring 4 in the fixed frame 3 along with the continuous pushing downwards of the second rope pulling block 7, and when the second rope pulling block 7 and the rope enter the left lower side of the fixed block 9, the first rope pulling block 6 also moves rightwards to press the upper side of the second rope pulling block 7 under the thrust of the spring 4. At this time, the fixing block 9, the second rope pulling block 7 and the first rope pulling block 6 are in close contact, and the ropes on the fixing block 9, the second rope pulling block 7 and the first rope pulling block 6 are tightly pressed. At the moment, the transverse pipe 1 is held by hand to pull the rope.
When the use is finished, the first rope pulling block 6 is moved leftwards by hands, and meanwhile, the second rope pulling block 7 is moved upwards to the upper part of the fixed block 9 and the first rope pulling block 6. The rope is taken out, and the rope wound between the tooth-shaped plates 12 is also unwound.
The utility model has the advantages that: through setting up the tooth shaped plate and having increased the frictional force to production when pulling the rope, can firmly grasp the rope, the rethread fixed block, first rope pulling piece and the cooperation of second rope pulling piece are fixed the rope is tighter, prevent that the rope from skidding. The rope pulling device is simple in structure, reliable in work and convenient to use. The work efficiency of the workers can be improved, and the harm to the hands can be reduced.
