Description

Technical Field

[0001] The invention relates to the technical field of wire clamps, and in particular to a wire clamp that is easy to recycle. Background Art

[0002] Wire grippers are commonly used wire gripping tools in the construction and maintenance of electric power, telecommunications, and railway electrification overhead lines. Wire grippers are used in different working conditions and hold different types and specifications of wires. They are divided into: aluminum alloy wire grippers, insulated wire grippers, steel strand wire grippers (applicable to steel strand wires), frog-type wire grippers, and anti-twist wire rope grippers. Each type of wire gripper has a variety of sizes and specifications.

[0003] Currently, when using wire clamps for overhead transmission and distribution line operations, when the wire clamp is clamped at a distant position on the conductor, the operator cannot grasp the tool for adjustment and retraction by simply extending his arms. At this time, the operator usually uses auxiliary materials such as long wooden sticks, ring sticks, etc. to retract the wire clamp, resulting in low work efficiency and the risk of falling. At the same time, the wire clamp dropped from a high altitude quickly contacts the ground, and its impact force causes the wire clamp to be easily damaged, making it difficult to guarantee the service life of the wire clamp.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0034] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0035] Reference Figure 1-Figure 8 As shown, a wire clamp for easy recycling includes a main board 1, a lower jaw 2 is arranged at the bottom of the main board 1, a pull rod 3 is inserted on the main board 1, one end of the pull rod 3 is rotatably connected to a connecting plate 4 through a first rotating shaft, one side of the connecting plate 4 is rotatably connected to the main board 1 through a second rotating shaft, and the side of the connecting plate 4 away from the second rotating shaft is rotatably connected to an upper jaw 5 through a third rotating shaft, and also includes:

[0036] The wire take-up assembly 6 is installed on the main board 1. When the wire clamp is recovered, the pull rod 3 can be pulled by the wire take-up assembly 6 to open the wire clamp;

[0037] The self-locking component 7 is installed on the side of the main board 1 away from the connecting plate 4, and the self-locking component 7 is connected to the second rotating shaft. In a normal state, the self-locking component 7 limits the rotation direction of the second rotating shaft, and can only allow the upper jaw 5 to move toward the direction of the lower jaw 2. In this way, when clamping the line, the line can only be clamped tighter and tighter to prevent the line clamp from accidentally opening when it is loosened in the middle;

[0038] The unlocking component 8 is installed on the main board 1, and the two ends of the unlocking component 8 are respectively connected to the wire taking-up component 6 and the self-locking component 7. After the wire taking-up component 6 is started, the unlocking component 8 will be driven first, and the unlocking component 8 will open the self-locking component 7. At this time, the wire taking-up component 6 will drive the pull rod 3 and finally open the wire clamp;

[0039] The cover plate 9 is rotatably disposed on the third rotating shaft and is used to limit the line. The cover plate 9 is also provided with a limiting component 10 connected to the lower jaw 2;

[0040] When initially clamping the line, the cover plate 9 can be flipped upward to open it, and then the line is placed in the line holder. Then the cover plate 9 is flipped downward again, and the limit assembly 10 is clamped in the lower jaw 2, so that the line is blocked in the line holder. In this way, after the line holder is opened, the line holder can be prevented from falling off the line, and can be moved back along the line when it is recovered.

[0041] In one embodiment, the wire take-up assembly 6 includes a wire take-up device 61, which is connected to the main board 1 through a support frame. A cable 62 is wound inside the wire take-up device 61. The wire take-up device 61 can adopt a structure similar to a tape measure, that is, a spring is provided inside the wire take-up device 61, and the cable 62 is connected to the spring. After the cable 62 is stretched, the spring is compressed, and when it is recovered, the cable 62 can be automatically reeled and recovered. A first fixed shaft 31 is provided on the pull rod 3, and a ring 63 sleeved on the first fixed shaft 31 is fixedly provided at one end of the cable 62 away from the wire take-up device 61. A first guide roller 64, a second guide roller 65 and a third guide roller 66 are also provided on the main board 1. The cable 62 passes through the first guide roller 64, the unlocking assembly 8, the second guide roller 65 and the third guide roller 66 in sequence.

[0042] When using the wire gripper, the staff carries the wire retractor 61 on their body, and the cable 62 can be stretched at any time. When retrieving the wire gripper, the cable 62 can be pulled, and the cable 62 can pull the ring 63 on the pull rod 3 through transmission, thereby pulling the pull rod 3 inward to open the wire gripper.

[0043] In one embodiment, a second fixed shaft 611 is provided at one end of the wire take-up device 61, and a telescopic button 612 is slidably provided inside the second fixed shaft 611. The telescopic button 612 has a certain elasticity and can be contracted by pressing inwards. After being released, the telescopic button 612 will also pop outwards. The wire take-up device 61 is connected to the support frame through the telescopic button 612. When the wire take-up device 61 is removed, it can be pressed inwards to make the telescopic button 612 detach from the support frame.

[0044] In one embodiment, the unlocking assembly 8 includes a driving rod 81, the middle portion of the driving rod 81 is connected to the main board 1 via a fourth rotating shaft, one end of the driving rod 81 is connected to the self-locking assembly 7, and the other end of the driving rod 81 is provided with a driving assembly, which is connected to the cable 62;

[0045] When in use, pulling the pull rod 3 outward will only cause the upper jaw 5 to move toward the lower jaw 2 and be locked by the self-locking component 7, preventing it from moving in the opposite direction. Therefore, when recycling, it is necessary to first open the self-locking component 7 through the driving component, and then pull the pull rod 3 through the cable 62 to open the wire gripper.

[0046] In one embodiment, the driving assembly includes a first pressure rod 82, a pressure roller 83 is arranged on the first pressure rod 82, the cable 62 is closely attached to the pressure roller 83, a vertical groove is opened on the main board 1, a second pressure rod 84 fixed on the first pressure rod 82 is arranged in the vertical groove, a first compression spring 85 is arranged at the bottom of the second pressure rod 84, and the second pressure rod 84 is connected to the bottom of the vertical groove through the first compression spring 85;

[0047] When the cable 62 is pulled, the cable 62 will first start the driving assembly, that is, the cable 62 between the first guide roller 64 and the second guide roller 65 will be gradually straightened and push the first pressure rod 82 downward, and the first pressure rod 82 will also press down the driving rod 81, so that the other end of the driving rod 81 is lifted upward to open the self-locking assembly 7.

[0048] In one embodiment, the self-locking assembly 7 includes a ratchet 71 connected to the second rotating shaft, a ratchet bar 72 is provided on one side of the ratchet 71, a first baffle 73 is provided on one side of the ratchet bar 72, a second baffle 74 is provided on the other side of the ratchet bar 72, a return spring 75 is provided between the ratchet bar 72 and the second baffle 74, and a driven rod 721 connected to the driving rod 81 is also provided on the ratchet bar 72;

[0049] By adopting the setting of the ratchet 71 and the ratchet bar 72, the rotation of the second rotating shaft can be limited. When the driving component is not used, only the upper jaw 5 will move in the direction of the lower jaw 2. After starting the driving component, the end of the driving rod 81 away from the first pressure rod 82 will be tilted upward, thereby pushing the ratchet bar 72 to deflect and make the ratchet bar 72 disengage from the ratchet 71. At this time, the pull rod 3 can be pulled by the cable 62 to open the wire clamp.

[0050] In one embodiment, the limiting assembly 10 includes a mounting frame 101 fixed on the cover plate 9, a limiting rod 102 is inserted into the mounting frame 101, a pressing plate 103 located in the mounting frame 101 is sleeved on the limiting rod 102, a limiting spring 104 sleeved on the limiting rod 102 is provided on the pressing plate 103 and the mounting frame 101, and a movable groove 21 matching with the limiting rod 102 is opened on the lower jaw 2;

[0051] After the line is clamped in the wire clamp, flip the cover plate 9 downward, then pull the limit rod 102 to shrink it, and release it when it is aligned with the movable groove 21. The limit rod 102 will be inserted into the movable groove 21 under the elastic force of the limit spring 104, and the movable groove 21 itself is relatively loose. The limit rod 102 can swing left and right and slide up and down in the movable groove 21. When the wire clamp is opened, the upper jaw 5 moves upward, which will drive the cover plate 9 to move upward as well. While loosening the line, it can also be hung on the line through the cover plate 9 to prevent the wire clamp from falling. When recycling, the wire clamp can be moved back along the line.

[0052] In one embodiment, a guide assembly 11 is further provided in the main board 1 , and the guide assembly 11 is clamped on the upper and lower sides of the pull rod 3 to guide the pull rod 3 , reduce the friction between the pull rod 3 and the main board 1 , and facilitate the movement of the pull rod 3 .

[0053] In one embodiment, the guide assembly 11 includes a fixed frame 111, a movable frame 112 is slidably disposed in the fixed frame 111, a roller shaft 113 is rotatably disposed in the inner cavity of the movable frame 112, both ends of the movable frame 112 are welded with lifting sliders 114 slidably disposed with the fixed frame 111, a second compression spring 115 is disposed at the bottom of the movable frame 112, and the movable frame 112 is connected to the bottom of the fixed frame 111 through the second compression spring 115, and both inner side walls of the fixed frame 111 are provided with protrusions 116;

[0054] Since the pull rod 3 moves along a certain curve, in order to allow the roller 113 to change accordingly with the moving direction of the pull rod 3 at any time, the guide component 11 is set to a structure that can bounce up and down, and the roller 113 can always be close to the surface of the pull rod 3 to facilitate the forward and backward movement of the pull rod 3.

[0055] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
