Description

Technical Field

[0001] The utility model relates to the technical field of steel wire ropes, in particular to a rope clamp. Background Art

[0002] A wire rope clamp is a clamp used for temporary connection and fixation of wire ropes. It is mainly used for temporary connection of wire ropes and fixation of the rear hand rope when the wire rope is passed through the pulley block, as well as fixation of the head of the cable wind rope on the raft. It is a widely used wire rope clamp in lifting and hoisting operations. Conventional wire rope clamps are generally composed of a U-shaped ring with a tightening thread, a clamp and a nut. During use, when the rope clamp and the wire rope slide relative to each other, there is no limiting structure to prevent the rope clamp and the wire rope from continuing to slide relative to each other, which poses a risk of the wire rope slipping off, resulting in poor safety in the use of the rope clamp. Utility Model Content

[0003] In view of this, the utility model provides a rope clamp to solve the problem that when the rope clamp and the wire rope slide relative to each other, there is a lack of a limiting structure to prevent the relative sliding, thereby resulting in poor safety in the use of the rope clamp.

[0004] The utility model provides a rope clamp for clamping a steel wire rope, the rope clamp comprising:

[0005] A ferrule, including passages extending through both ends thereof;

[0006] A clamping block is rotatably disposed in the channel;

[0007] Two pressing blocks, part of which is located in the channel and on both sides of the clamping block, and a receiving cavity partially overlapping with the channel is formed between the clamping block and the two pressing blocks respectively, and a part of the steel wire rope is passed through the receiving cavity and clamped by the pressing block and the clamping block; a through hole is opened in the side wall of the ferrule corresponding to the receiving cavity, and the through hole is suitable for the steel wire rope to pass through, and when the steel wire rope slides relative to the ferrule, the clamping block is suitable for rotating around its rotation axis to change the spacing between it and the pressing block.

[0008] Beneficial effect: When the wire rope and the clamp block slide relative to each other, the friction between the wire rope and the clamp block drives the clamp block to rotate in the sliding direction of the wire rope, thereby reducing the spacing between the clamp block and the pressure block, and then increasing the slip resistance of the wire rope by squeezing the wire rope, which is beneficial to reduce the risk of wire rope slipping and improve the safety of rope clamp use.

[0009] In an optional embodiment, the pressing block includes a threaded portion at least part of which is located in the channel, and an internal thread is provided on the inner wall of the channel corresponding to the threaded portion, so that the pressing block and the ferrule form a threaded connection.

[0010] Beneficial effects: The pressing block is threadedly connected to the ferrule. By rotating the pressing block, the size of the accommodating cavity between it and the clamping block can be adjusted, so as to be applicable to wire ropes of different specifications, which is beneficial to improving the applicability of the wire rope clip.

[0011] In an alternative embodiment, the channel is in a straight tubular shape. A sliding block is arranged between the threaded portion and the clamping block. The sliding block is slidably arranged in the accommodating cavity, and the threaded portion presses against the wire rope through the sliding block. Define the end face in contact with the wire rope of the clamping block as the first end face, and define the end face in contact with the wire rope of the sliding block as the second end face. The second end face is parallel to the first end face.

[0012] Beneficial effects: By making the first end face parallel to the second end face, when clamping the wire rope through the clamping block and the sliding block, it is convenient to achieve full contact between the wire rope and the first end face and the second end face, which is beneficial to improving the stability of the clamping operation.

[0013] In an alternative embodiment, the angle between the first end face and the axis of the channel is A, where 75° ≤ A ≤ 80°.

[0014] In an alternative embodiment, the pressing block further includes a fixing portion at least partially disposed outside the ferrule. The fixing portion is coaxially and fixedly connected to the threaded portion, and the operator drives the threaded portion to rotate by rotating the fixing portion.

[0015] In an alternative embodiment, a local area of the end face of the fixing portion facing away from the threaded portion is recessed to form an abutting groove, and the operator rotates the fixing portion through the abutting groove.

[0016] Beneficial effects: By providing an abutting groove on the end face of the fixing portion facing away from the threaded portion, it is convenient for the operator to rotate the fixing portion through the abutting groove, and then drive the threaded portion to rotate.

[0017] In an alternative embodiment, a local area of the end face of the fixing portion facing away from the threaded portion protrudes to form a convex block, and the operator rotates the fixing portion through the convex block.

[0018] Beneficial effects: By providing a convex block on the end face of the fixing portion facing away from the threaded portion, it is convenient for the operator to rotate the fixing portion through the convex block, and then drive the threaded portion to rotate.

[0019] In an alternative embodiment, a rotating shaft is arranged inside the channel, and the clamping block is sleeved on the rotating shaft so that the clamping block is rotatably connected to the ferrule. Description of the Drawings

[0029] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] The following Figures 1 to 3 is combined to describe the embodiments of the present utility model.

[0031] According to an embodiment of the present utility model, a wire rope clip is provided for clamping a wire rope 2. The wire rope clip includes:

[0032] A ferrule 1 including a channel 101 penetrating through both ends thereof;

[0033] A clamping block 3 rotatably disposed in the channel 101;

[0034] Two pressing blocks 4, with partial regions located in the channel 101 and on both sides of the clamping block 3. Accommodating cavities 7 overlapping with part of the channel 101 are respectively formed between the clamping block 3 and the two pressing blocks 4. A partial region of the wire rope 2 is threaded through the accommodating cavities 7 and is clamped by the pressing blocks 4 and the clamping block 3. A through hole 102 is provided in the side wall of the ferrule 1 corresponding to the accommodating cavity 7, and the through hole 102 is adapted for the wire rope 2 to pass through. When the wire rope 2 slides relative to the ferrule 1, the clamping block 3 is adapted to rotate around its rotation axis to change the interval distance between it and the pressing block 4.

[0035] For the wire rope clip provided in this embodiment, when the wire rope 2 slides relative to the clamping block 3, under the frictional force between the wire rope 2 and the clamping block 3, the clamping block 3 is driven to rotate in the sliding direction of the wire rope 2, so as to reduce the interval distance between the clamping block 3 and the pressing block 4, and further increase the slippage resistance of the wire rope 2 by squeezing the wire rope 2, which is beneficial to reducing the slippage risk of the wire rope 2 and improving the use safety of the wire rope clip.

[0036] Specifically, along the direction perpendicular to the rotation axis of the clamping block 3, the size of the clamping block 3 is smaller than the inner diameter of the channel 101, so as to facilitate the rotation of the clamping block 3 within the channel 101. The two pressing blocks 4 are respectively located on both sides of the clamping block 3 to form a receiving cavity 7 on both sides of the clamping block 3. The steel wire rope 2 is adapted to slide relative to the ferrule 1 along its length direction, so that the length direction of the steel wire rope 2 located within the receiving cavity 7 is arranged at an angle to the rotation axis of the clamping block 3. Thus, when the steel wire rope 2 slides relative to the clamping block 3, the clamping block 3 is driven to rotate along the sliding direction of the steel wire rope 2 through the frictional force between the steel wire rope 2 and the clamping block 3, so as to reduce the interval distance between the clamping block 3 and the pressing block 4, thereby enabling the clamping block 3 and the pressing block 4 to further squeeze and clamp the steel wire rope 2, enhancing the slippage resistance of the steel wire rope 2, and further preventing the steel wire rope 2 from slipping. As a preferred implementation form, the rotation axis of the clamping block 3 is perpendicular to the axis of the channel 101, and the length direction of the steel wire rope 2 located inside the receiving cavity 7 is perpendicular to the rotation axis of the clamping block 3.

[0037] A through hole 102 is formed in the side wall of the ferrule 1 corresponding to the position of the steel wire rope 2, and the through hole 102 communicates with the receiving cavity 7. The through hole 102 is adapted for the steel wire rope 2 to pass through. Two through holes 102 are formed in the side wall of the ferrule 1 corresponding to each receiving cavity 7, so as to facilitate the steel wire rope 2 to enter the receiving cavity 7 through one through hole 102 and pass through the ferrule 1 through the other through hole 102. After the steel wire rope 2 passes through the ferrule, it extends into the other receiving cavity 7 through one of the two through holes 102 corresponding to the other receiving cavity 7 and passes through the ferrule 1 through the other of the two through holes 102, so that the steel wire rope 2 is arranged in a U shape on the ferrule 1. The channel 101 is in a straight tube shape. Preferably, along the length direction of the channel 101, the projections of the two through holes 102 on the same side of the two receiving cavities 7 overlap.

[0038] In some embodiments, as shown in Figures 1 to 3 the pressing block 4 includes a threaded portion 41 at least partially located within the channel 101, and an internal thread is provided on the inner wall of the channel 101 corresponding to the threaded portion 41, so that the pressing block 4 is threadedly connected to the ferrule 1.

[0039] For the wire clamp provided in this embodiment, the pressing block 4 is threadedly connected to the ferrule 1. By rotating the pressing block 4, the size of the receiving cavity 7 between it and the clamping block 3 can be adjusted, so as to be applicable to steel wire ropes 2 of different specifications, which is beneficial to improving the applicability of the wire clamp.

[0040] Specifically, rotate the pressing block 4 to adjust the distance between it and the clamping block 3. Before threading the steel wire rope 2, rotate the pressing block 4 to move it away from the clamping block 3, increasing the space of the accommodating cavity 7, so as to reserve sufficient space for threading steel wire ropes 2 of different specifications, which is beneficial to improving the operation convenience and the applicability of the wire rope clip; when the steel wire rope 2 is threaded in place, rotate the pressing block 4 to move it towards the clamping block 3 until the steel wire rope 2 is pressed against the clamping block 3, so that the steel wire rope 2 is clamped on the wire rope clip by the pressing block 4 and the clamping block 3.

[0041] In some embodiments, as shown in Figures 1 to 3 the channel 101 is in a straight tube shape, and a sliding block 5 is arranged between the threaded portion 41 and the clamping block 3. The sliding block 5 is slidably arranged in the accommodating cavity 7, and the threaded portion 41 presses against the steel wire rope 2 through the sliding block 5; define the end face of the clamping block 3 in contact with the steel wire rope 2 as the first end face, and define the end face of the sliding block 5 in contact with the steel wire rope 2 as the second end face, and the second end face is parallel to the first end face.

[0042] For the wire rope clip provided in this embodiment, by making the first end face parallel to the second end face, when clamping the steel wire rope 2 through the clamping block 3 and the sliding block 5, it is convenient to achieve full contact between the steel wire rope 2 and the first end face and the second end face, which is beneficial to improving the stability of the clamping operation.

[0043] Specifically, the sliding block 5 is arranged between the clamping block 3 and the pressing block 4. Define the state when the sliding block 5 and the clamping block 3 initially press against the steel wire rope 2 as the initial state. In the initial state, the first end face is arranged at an acute angle with the axial direction of the channel 101, the second end face of the sliding block 5 is parallel to the first end face, and relative to the first end face being perpendicular to the axial direction of the channel 101, the first end face is arranged at an acute angle with the axial direction of the channel 101, so that the steel wire rope 2 has a larger contact area with the first end face and the second end face, which is beneficial to improving the clamping stability, and makes the direction of the frictional force received by the clamping block 3 tilt towards the side close to the axis of the clamping block 3, which is beneficial to driving the clamping block 3 to rotate around its own axis under the action of the frictional force.

[0044] In some embodiments, as shown in Figures 1 to 3 the included angle between the first end face and the axis of the channel 101 is A, where 75° ≤ A ≤ 80°.

[0045] Specifically, in the initial state, the included angle between the first end face of the clamping block 3 and the axial direction of the channel 101 is 75° to 80°. As a preference, in the initial state, the included angle between the first end face and the axial direction of the channel 101 is 78°.

[0046] In some embodiments, as shown in Figures 1 to 3As shown, the pressing block 4 also includes a fixing portion 42 at least part of which is arranged outside the ferrule 1 . The fixing portion 42 is coaxially fixedly connected with the threaded portion 41 . The operator rotates the fixing portion 42 to drive the threaded portion 41 to rotate.

[0047] Specifically, the fixing portion 42 is located on a side of the threaded portion 41 away from the clamping block 3 , and at least a portion of the fixing portion 42 is located outside the clamping sleeve 1 , so that an operator can easily rotate the threaded portion 41 by rotating the fixing portion 42 .

[0048] In some embodiments, in combination Figures 1 to 3 As shown, a local area of the end surface of the fixing portion 42 away from the threaded portion 41 is recessed to form an abutment groove 421 , and an operator rotates the fixing portion 42 through the abutment groove 421 .

[0049] The rope clamp provided in this embodiment has an abutment groove 421 formed on the end surface of the fixing portion 42 away from the threaded portion 41 , so that an operator can rotate the fixing portion 42 through the abutment groove 421 , thereby driving the threaded portion 41 to rotate.

[0050] Specifically, the abutment groove 421 is formed by a depression in the middle area of the end surface of the fixing portion 42 away from the threaded portion 41. The abutment groove 421 includes a straight-shaped, a cross-shaped, and a hexagonal type, so that the operator can rotate the fixing portion 42 through a tool (such as a screwdriver, a hexagonal wrench), and the rotation axis of the abutment groove 421 coincides with the rotation axis of the threaded portion 41.

[0051] In some embodiments, in combination Figures 1 to 3 As shown, a local area of the end surface of the fixing portion 42 facing away from the threaded portion 41 protrudes to form a convex block 422 , and an operator rotates the fixing portion 42 through the convex block 422 .

[0052] The rope clamp provided in this embodiment is provided with a protrusion 422 on the end surface of the fixing portion 42 away from the threaded portion 41 , so that the operator can rotate the fixing portion 42 through the protrusion 422 , thereby driving the threaded portion 41 to rotate.

[0053] Specifically, the end surface of the fixing portion 42 away from the threaded portion 41 can be provided with either an abutment groove 421 or a protrusion 422, or both can be provided at the same time. When the protrusion 422 and the abutment groove 421 are provided at the end surface of the fixing portion 42 away from the threaded portion 41, the position of the protrusion 422 avoids the abutment groove 421.

[0054] In some embodiments, in combination Figures 1 to 3 As shown, a rotating shaft 6 is disposed inside the channel 101 , and the clamping block 3 is sleeved on the rotating shaft 6 , so that the clamping block 3 and the clamping sleeve 1 form a rotational connection.

[0055] Preferably, the axis of the rotating shaft 6 is perpendicular to the axis of the channel 101, and the midpoint of the axis of the rotating shaft 6 coincides with the midpoint of the channel 101. The clamping block 3 is adapted to rotate around the axis of the rotating shaft 6 on the rotating shaft 6.

[0056] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations fall within the scope defined by the present invention.
