Description

Technical Field

[0002] During the installation of transmission lines, the tightening construction is an important part of the tension stringing construction of overhead transmission lines, and it is also an important part of the tension stringing construction process. After the tension is released, the conductor has been deployed on the transmission line tower, and the tightening construction is required to make the conductor sag meet the design operation requirements. In the existing tightening construction process, wire clamps, pulleys, shackles, and temporary anchor wires are usually used to tighten the conductors, and the temporary anchor wires are pulled by motorized capstans or hand winches to gradually tighten the conductors and finally meet the design sag requirements.

[0003] At present, during the construction of overhead wire tightening and sag adjustment, high-altitude workers need to carry a wire clamp to "exit the wire". When installing a wire clamp for "exiting the wire" with a large height difference, ground wire, and fewer split wires, high-altitude workers need to "go downhill", "climb", and "hang" to exit the wire, which places high physical requirements on high-altitude workers and has a high safety risk of "exiting the wire". This process has high labor intensity and high safety risks, especially for single split wires and ground wires, which are more difficult to exit the wire manually. Therefore, it is necessary to design a wire clamp pusher to replace manual carrying of the wire clamp to "exit the wire".

[0004] The existing publicly available wire gripper pushing devices are generally integrated, and the wire gripper is fixedly installed on the pushing device. Each wire gripper needs to be equipped with a pushing trolley, and the equipment laying cost is high. Summary of the invention

In the initial state, the self-locking mechanism 6 and the opening and closing mechanism 13 are both in the retracted state and are not connected to the wire clamp. The self-locking mechanism 6 is directly opposite to the pre-installed connecting piece 3, and the opening and closing mechanism 13 is opposite to the movable pin shaft 22 of the wire clamp 2. During the pushing operation, the remote control device sends a control instruction to the controller to control the opening and closing mechanism to extend and press against the wire clamp, and the controller controls the running mechanism to realize the pushing of the wire clamp. When the wire clamp is installed, the controller controls the opening and closing mechanism to retract, and the running mechanism drives the pushing and recovery device body to withdraw offline, and other wire clamp installation work can be carried out. When the wire clamp work is completed, the pushing and recovery device body is put online, and the remote control device sends a control instruction to the controller to control the clamping mechanism 12 to clamp the line. The running mechanism moves the pushing and recovery device body to the vicinity of the wire clamp, and extends through the self-locking mechanism to connect with the pre-installed connecting piece pre-installed on the wire clamp. The wire clamp can be automatically connected back by the running mechanism. Each construction site only needs to be equipped with one pushing and recovery device body, which is low in cost.

The lower ends are bent inwards and the ends are equipped with symmetrical clamping wheel mounting plates 125. The two clamping wheel mounting plates 125 are trumpet-shaped with the bottom opening outwards. Two groups of symmetrical clamping wheels 128 are arranged on the two clamping wheel mounting plates 125. The output shaft of the screw motor 126 is threadedly connected to the inner hole of the connecting piece 127. The screw motor 126 is connected to the connecting piece 7 to drive the clamping arms 124 of the two rod assemblies to open and close, so that the clamping wheels 128 clamp or release the wire. The screw motor 126 is connected to the housing through the motor base plate 121. The two ends of the screw motor 126 are symmetrically provided with vertical fixed arms 122. One end of the connecting arm 123 is hinged to the lower end of the fixed arm 122, and the other end is hinged to the middle of the clamping arm 124. The upper end of the fixed arm 122 is fixed in the housing 5. The clamping mechanism 12 is opened and closed by a screw motor 126, which makes it easy to install the wire and the clamping force can be adjusted autonomously.

[0026] like Figure 5 The pre-installed connector 3 includes a U-shaped card plate, which is clamped on the upper clamping die 21 of the wire clamp 2. There are clearance holes on the two parallel clamping plates a32 of the U-shaped card plate, the clamping plates b33 and the corresponding positions of the upper clamping die 21.

The U-shaped card plate extends a connecting plate 34 to one side of the housing 5, and a slot is provided at the end of the connecting plate 34. Clamping plates a32 and b33 are installed on both sides of the wire clamp, locked with bolts 31, clamping the wire clamp and the connecting plate 34, and used in conjunction with the self-locking mechanism 6 when in use. There is a clearance hole at the lower end of the clamping plate a32 for the upper pin of the upper clamping die 21, and there is a semicircular notch at the lower end of the clamping plate b33 for the upper pin of the upper clamping die 21.

[0027] like Figure 6 The opening and closing mechanism 13 includes a push rod and a translation driving device for driving the push rod to translate and retract. The translation driving device includes a rack 134 and a gear 136 that mesh with each other. One end of the rack 134 is fixed on the slider 132, and the other end is supported on the support bearing 137. The support bearing 137 is supported on the housing 5 through a fixed shaft 138. The slider 132 is slidably connected to the guide rail 131. The guide rail 131 and the motor 135 are mounted on the mounting plate 131. The gear 136 is mounted on the output shaft of the motor 135. The rack 134 is directly opposite to the active pin 22 of the wire clamp 2. There is a window on the side of the housing 5 close to the wire clamp 2 to give way to the rack 134. The motor 135 drives the gear to rotate, and then drives the rack 134 to move forward and backward. The front end of the rack 134 extends out of the housing 5 and pushes against the active pin 22 hinged between the lower jaw of the wire clamp and the upper clamping die 21, so that the lower jaw is disengaged and the wire 1 is released. The implementation method using the gear rack opening and closing mechanism 13 has large torque and simple control.

[0028] like Figure 7 , Figure 8As shown, the rotating mechanism 8 includes more than three clamping wheels arranged around the outer periphery of the conductor 1, a clamping drive device for driving the clamping wheels to clamp the conductor 1, and a rotating motor 86 for driving one of the clamping wheels to rotate; the three clamping wheels are arranged around the outer periphery of the conductor, two of which are auxiliary clamping wheels 89, and the other is a driving wheel 84, and the clamping drive device for driving the three clamping wheels to loosen or clamp synchronously includes a fixed plate 87, a rotating member 83 located on the outer periphery of the fixed plate 87, and a rotating drive device for driving the rotating member 83 to rotate around the center line of the fixed plate 87; the fixed plate 87 and the rotating member 83 are concentrically arranged, and both are semi-annular structures with a notch at the bottom, and the fixed plate 87 is arranged with waist rings corresponding to the three clamping wheels one by one. The rotating member 83 is provided with hinge seats corresponding to the three clamping wheels one by one; each clamping wheel is mounted on one end of the clamping wheel connecting rod 88, and the other end and the middle of the clamping wheel connecting rod 88 are opened and respectively hinged in the corresponding hinge seat and waist-shaped hole through the hinge shaft; the rotary drive device includes a connecting rod assembly 82 and a clamping motor 81; the connecting rod assembly 82 includes a connecting arm 1, a connecting arm 2, a connecting wall 3 and a connecting wall 4, one end of the connecting wall 2 is hinged to one end of the connecting arm 1, and the other end is hinged to one end of the connecting wall 3 and the connecting wall 4, the other end of the connecting wall 1 is fixed to the output shaft of the clamping motor 81, the other end of the connecting wall 4 is hinged to the rotating member 83, and the other end of the connecting wall 3 is hinged to the hinge seat in the housing 5; the mounting seat of the clamping motor 81 is fixed in the housing 5. The rotating motor 86 is used to drive the driving wheel 84 to rotate, and the rotating motor 86 is mounted on the motor seat 85, and the motor seat 85 and the fixing plate 87 are fixed to the housing through the connecting rod. The four connecting arms of the connecting rod assembly 82 are parallel to the rotation plane of the rotating part 83, and the output shaft of the clamping motor 81 is perpendicular to the rotation plane of the rotating part 83. The rotation of the output shaft of the clamping motor 81 drives the connecting wall 1 to rotate around the output shaft. The rotation of the connecting wall 1 drives the connecting wall 2 and the connecting wall 3 to move. The movement of the connecting wall 2 drives the rotating part 83 to rotate around the center line of the fixed plate 87.

[0029] The clamping motor 81 rotates through the connecting rod assembly 82 to drive the rotating part 83 to rotate, and the clamping wheel connecting rod 88 drives the auxiliary clamping wheel 89 and the driving wheel 84 to clamp the wire 1. The driving wheel 84 is driven to rotate by the rotating motor 86 to realize the free rotation of the whole machine along the wire. When the wire clamp is recovered, the push recovery device body moves to the wire clamp attachment, and the entire push recovery device body is driven to rotate around the wire through the rotating mechanism 8. The push recovery device body is aligned with the wire clamp. Only after alignment can the self-locking mechanism 6 and the pre-installed connector 3 be aligned, and the self-resetting hook of the self-locking mechanism 6 can be hung in the groove at one end of the connecting plate 34 of the pre-installed connector 3 after being extended.

[0030] like Fig. 9As shown, two side mounting plates 65 are symmetrically fixed in the housing 5, and a slide rail 68 is set at the bottom of the mounting plates 65 on both sides. A telescopic plate 61 is slidably connected in the slide rail 68. A rack 64 is set on the telescopic plate 61, and the rack 64 is meshed with a gear 67. The rotating shaft of the gear 67 passes through the bearing fixed on one side mounting plate 65 and is connected to the motor 66. The telescopic plate 61 is provided with a slot near one end of the connecting plate 34, and a slot is hinged in the slot to cooperate with a slot at one end of the connecting plate 34 of the pre-installed connecting member 3. The locked self-resetting hook 62 has a spring 63 installed between the upper end of the self-resetting hook 62 and the middle of the telescopic plate 61. The spring 63 facilitates the reset of the self-resetting hook 62. When the telescopic plate 61 extends toward one end of the pre-installed connector 3, it pushes forward and fits with the connecting plate at one end of the pre-installed connector 3. The connecting plate lifts the self-resetting hook, and the telescopic plate continues to move forward. When the self-resetting hook 62 reaches the slot at one end of the connecting plate, the self-resetting hook 62 is tightened and reset due to the spring force and snaps with the pre-installed connector 3. The housing 5 has a window of the self-locking mechanism on one side close to the connecting plate 34; a travel switch 69 is fixed on the mounting plate 65 opposite to the gear 1 67, and two bosses cooperating with the travel switch 69 are arranged side by side on one side of the telescopic plate 61. When the travel switch 69 contacts the boss, a signal is sent to the controller, and the controller controls the motor 1 66 to rotate forward and reverse to achieve rack limit.

[0031] The motor drives the gear to rotate, and then the rack drives the telescopic plate to move forward and backward. The controller collects the signal of the travel switch, and then controls the motor to move forward and backward to achieve the travel purpose. When it reaches the front, the self-resetting hook extends into the card slot on the connecting plate 34 of the pre-installed connector 3 to complete the self-locking. The self-locking mechanism 6 allows the wire clamp 2 to be quickly connected when it is recovered, and it is one-way opening and closing, easy to operate, and not easy to disengage.

[0032] When working, first install the pre-installed connector 3 on the wire gripper 2, then place the wire gripper 2 and the push-and-recovery device body on the wire 1, control the clamping mechanism 12 to automatically push the wire gripper to fix the recovery device on the wire 1, control the gear rack opening and closing mechanism 13 to extend and support the movable pin 22 of the wire gripper, drive the active wheel 10 to rotate to drive the push-and-recovery device body forward and push the wire gripper 2 forward to reach the predetermined position, tighten the drag rope of the wire gripper 2 to lock the wire gripper 2 on the wire 1, and when working, use the U-shaped hook under the wire gripper to connect the drag rope for tightening the wire. After the wire gripper is in place, tighten the rope, and the wire gripper jaws automatically clamp on the wire. Drive the active wheel 10 to reverse and control the push-and-recovery device body to retract, open the clamping mechanism 12, and remove the push-and-recovery device body.

[0033] When the wire is tightened, the push recovery device body is placed on the wire 1, the clamping mechanism 12 is tightened and fixed on the wire 1, and the driving wheel 10 is driven to rotate to drive the push recovery device body forward. When it is close to the wire clamp 2, the remote control device controls and sends a signal to the controller to control the driving wheel 10 to stop rotating, and at the same time drives the rotating mechanism 8 to clamp on the wire 1, opens the clamping mechanism 12, drives the rotating mechanism 8 motor to work, and the push recovery device body rotates along the wire 1. The infrared transmitter 4 transmits a signal until the infrared receiver receives the emitted infrared rays. At this time, the push recovery device body is aligned with the wire clamp 2. After alignment, the clamping mechanism 12 is tightened, the rotating mechanism 8 is loosened, the self-locking mechanism 6 is extended, and the telescopic plate 61 of the self-locking mechanism 6 is driven forward. When the self-locking mechanism 6 clamps the pre-installed connector 3, it stops, and the opening and closing mechanism 13 is controlled to extend, and the lower jaw of the locked state of the wire clamp 2 is opened, and the push recovery device body is controlled to drive the wire clamp 2 to retract, open the clamping mechanism 12, remove the wire clamp 2 and the push recovery device body, and the work is completed.
