Description

Technical Field

[0001] The invention relates to the technical field of cable conductor installation, in particular to a cable tightener for cable construction. Background Art

[0002] The existing tensioner is mainly fixed on the cross arm during operation. One end of the cable conductor is selected as the fixed end and installed on the first hook of the tensioner. Then the steel rope is loosened so that the second hook assembly can be moved to the other end of the cable conductor for installation. After the cable conductors at both ends are fixed, the wrench is pulled so that the wrench gradually winds the steel rope around the ratchet roller under the anti-reversal effect of the pawl to complete the tightening of the cable conductor. The problem with this tensioner is that when the cable conductors at both ends are not in the same parallel plane or the single-end conductor is in an inclined position, there is a connection height deviation because the cable conductor at the unfixed inclined end is not at the same connection height as the cable conductor at the fixed end, and the hook assembly installed at the moving end cannot adjust the fixed angle along the steel rope arrangement path according to the deviation. During assembly, the operator needs to manually straighten the hook assembly in the unconnected state to prevent the hook assembly from moving along the outer side of the steel rope, so that the hook assembly can be aligned with the conductor in the inclined position before the fixing operation can be completed.

The press-fit locking drive 43 and the longitudinal movable shaft 42 are both slidably connected to the directional sliding support 41. The longitudinal movable shaft 42 is fixedly connected to the bottom of the press-fit locking drive 43. The longitudinal movable shaft 42 is rotatably connected to a staggered clamp 44. The staggered clamp 44 slides and extends to the inner side of the directional sliding support 41. A merging guide wedge 45 is provided on the inner side of the directional sliding support 41. The merging guide wedge 45 is used to provide a contact support surface when the staggered clamp 44 slides, so that the two staggered clamps 44 are merged in relative directions after sliding in contact with the merging guide wedge 45 under the pushing pressure of the press-fit locking drive 43.

[0020] In an optional implementation of the present embodiment, the directional sliding support 41 is provided with an anti-slip limiting groove 411, the longitudinal movable shaft 42 is slidably connected along the anti-slip limiting groove 411, and a pressure response switch 451 is arranged on the outer side of the merging guide wedge block 45. The pressure response switch 451 is used to detect the contact pressure generated by the staggered clamping head 44 and the merging guide wedge block 45 after the staggered clamping head 44 is slidably engaged. The staggered clamping head 44 is provided with an electromagnetic fixed lock 441, and the electromagnetic fixed lock 441 is connected to the pressure response switch 451 signal. When the electromagnetic fixed lock 441 obtains the contact signal transmitted by the pressure response switch 451, it is used to limit the merged staggered clamping head 44.

[0021] In this embodiment, in order to solve the technical problem proposed by the present invention, the present invention provides a wire diameter outer locking component 4 and an opposite moving end hooking mechanism 5. Figure 1 It can be known that the specific structural composition of the two-way transmission support 11, the driving ratchet 12 and the hand-operated handle 13 in the tightening wheel group 1. Since the working principle of the ratchet operation to tighten the steel rope is not the improved content of the present invention, it will not be repeated in this embodiment. When used in cable construction, the fixed angle of the opposite moving end hook mechanism 5 can be adjusted along the steel rope arrangement path according to the connection height deviation between the cable conductor to be tightened and the non-traction cable conductor. After the fixed angle debugging of the opposite moving end hook mechanism 5 is completed, the positioning locking of the opposite moving end hook mechanism 5 can be performed through the wire diameter outer locking component 4. The positioning locking operation principle of the wire diameter outer locking component 4 is: the interlaced clamping head 44 is driven to slide and extend to the inner side of the directional sliding support 41 by the press-fit locking drive 43, until the interlaced clamping head 44 is combined with the guide wedge block After sliding contact, the staggered clamps 44 are guided by the supporting surface of the merging guide wedge 45, and at the same time are pushed by the pressure of the pressing and locking drive 43, so that the two groups of staggered clamps 44 are merged in relative directions. At the same time, in the merged state, the staggered clamps 44 trigger the pressure sensing area of ​​the pressure response switch 451, and send a stop signal to the pressing and locking drive 43 and an enable signal to the electromagnetic fixing lock 441 through the pressure response switch 451, so that the electromagnetic fixing lock 441 is doubly locked by the pressing and locking drive 43 and the electromagnetic fixing lock 441 to fix the movable end support 51 and the steel rope, so that it cannot continue to slide and is always at the same connection height as the inclined wire. The operator can connect when the movable end support 51 is in a fixed state close to the cable.

[0022] In an optional implementation of the present embodiment, the directional sliding support 41 is provided with a clearance groove 412, which is used to provide expansion space for the staggered clamping head 44 in a non-merged state. A reset connecting member 431 is provided between the pressed locking drive member 43 and the staggered clamping head 44, and the reset connecting member 431 is used to push the staggered clamping head 44 to release the merger when the staggered clamping head 44 slides to the inner side of the clearance groove 412.

[0023] In this embodiment, the clearance groove 412 is used to provide a storage space for the staggered clamping head 44 when it is lifted up and opened. That is, after the compression locking drive member 43 drives the longitudinal movable shaft 42 to slide and rise along the anti-slip limiting groove 411 to reach the inner side of the clearance groove 412, the staggered clamping head 44 is no longer squeezed by the combined guide wedge block 45 and is elastically reset and expanded through the reset connector 431, so that the staggered clamping head 44 is in an open state and detached from the outside of the cable conductor, thereby releasing the connection between the movable end support 51 and the cable conductor. At this time, the operator can continue to slide the movable end support 51 along the outside of the steel rope to adjust the installation angle of the movable end support 51.

[0024] In an optional implementation of the present embodiment, the tightening wheel assembly 1 includes a two-way transmission support 11, a driving ratchet 12 and a hand-operated handle 13. The driving ratchet 12 is installed at one end of the two-way transmission support 11. The driving ratchet 12 is used to connect to an external driving member to control the anti-deviated hook seat 3 and the opposite moving end hook mechanism 5 to achieve expansion or contraction. The hand-operated handle 13 is fixedly connected to one side of the two-way transmission support 11. The hand-operated handle 13 is used to install the two-way transmission support 11 on a fixed support point. Among them, the hand-operated handle 13 is used as a manual driving end to drive the driving ratchet 12 to unwind or rewind the steel rope inside the two-way transmission support 11. In the present embodiment, the hand-operated handle 13 can also be set to be driven by an electric control machine, and the driving ratchet 12 is driven by the electric control machine to unwind or rewind the steel rope inside the two-way transmission support 11. Its driving method is a well-known technical means and will not be repeated here.

[0025] In an optional implementation of the present embodiment, the opposing mobile end hooking mechanism 5 includes a mobile end support 51, a transmission sleeve 52 and a mobile end hook 53. The anti-deviated hook seat 3 and the mobile end support 51 are respectively arranged at the two ends of the bidirectional transmission support 11. The mobile end support 51 is slidingly connected to the bidirectional transmission support 11. The transmission sleeve 52 is rotatably connected to the inner side of the mobile end support 51. The mobile end hook 53 is rotatably connected to the mobile end support 51 through the transmission sleeve 52. The directional sliding support 41 is fixedly connected to the outer side of the mobile end support 51.

[0026] In this embodiment, the movable end hook 53 and the anti-deviation hook seat 3 are respectively arranged as tightening wire connection ends between two wires to be tightened, wherein the anti-deviation hook seat 3 is used to connect the fixed end wire, and the movable end hook 53 is used to connect the tightening end wire to be moved. The movable end hook 53 can be rotated and adjusted along the axial direction through the setting of the transmission sleeve 52, thereby fitting the inclination and installation position of the tightening end wire.

[0027] In an optional implementation of the present embodiment, the external extension limiting mechanism 2 includes a rectangular guide seat 21 and a non-contact assembly frame 22, both of which are fixedly connected to the outside of the bidirectional transmission support 11, and the rectangular guide seat 21 is arranged at one end of the bidirectional transmission support 11 close to the movable end support 51, and the rectangular guide seat 21 is used to limit the moving path of the movable end support 51 when it is extended or tightened.

[0028] In this embodiment, after the non-contact assembly frame 22 is installed on the outer side of the bidirectional transmission support 11 through the rectangular guide seat 21, the non-contact assembly frame 22 limits the sliding path of the steel rope when it is wound and unfolded along the inner side of the bidirectional transmission support 11, preventing the steel rope from detaching from the inner side of the bidirectional transmission support 11.

[0029] The working principle and use process of the present invention are as follows: first, the ratchet wheel 12 is driven by the hand-operated handle 13 to loosen the wire rope coiled inside the bidirectional transmission support 11. After the wire rope is loosened, the anti-deviated hook seat 3 is preferentially connected to the fixed end wire, and the fixed angle of the opposite movable end hook mechanism 5 is adjusted along the wire rope arrangement path according to the connection height deviation between the cable wire to be tightened and the non-traction cable wire, that is, the movable end support 51 is slid along the wire rope arrangement path until the movable end support 51 is aligned with the cable wire to be tightened, and then the longitudinal movable shaft 42 is driven downward by the pressing and locking driving member 43, so that the staggered clamping head 44 moves downward with the longitudinal movable shaft 42. At this time, the staggered clamping head 44 is guided by the support surface of the combined guide wedge block 45, and moves in the relative direction under the pressure formed when the pressing and locking driving member 43 is pushed forward. Merge until the staggered clamping heads 44 in the merged state are completely merged and contact with the pressure sensing area of ​​the trigger pressure response switch 451, thereby triggering the pressure response switch 451 to send a stop signal to the pressing and locking driving component 43, and send an activation signal to the electromagnetic fixing lock buckle 441, so that the electromagnetic fixing lock buckle 441 is doubly locked by the pressing and locking driving component 43 and the electromagnetic fixing lock buckle 441 to fix the movable end support 51 and the steel rope, and cannot continue to slide, so that it is always at the same connection height with the wire in the inclined state. The operator can connect the movable end support 51 to the cable wire at the end to be tightened when the movable end support 51 is in a fixed angle state, avoiding the need for the operator to manually straighten the hook head assembly in the unconnected state during assembly, thereby facilitating the connection operation in a high-altitude assembly environment.
