Description

Technical Field

[0001] The utility model relates to the technical field of engineering construction, in particular to a lever-type installation spacer wrench. Background Art

[0002] Spacers are hardware that are installed on split conductors to fix the spacing between each split conductor to prevent the conductors from whipping each other and to suppress breeze vibration and sub-span oscillation. Spacers are generally installed in the middle of the span, 50 to 60 meters apart. The main requirements for spacers are that the wire clamps must have sufficient grip and are not allowed to loosen during long-term operation. The overall strength must be able to withstand the centripetal force of each split conductor when the line is short-circuited and fatigue under long-term vibration. Spacers can be divided into two categories based on performance: damping and rigidity. Damping spacers have wear-resistant rubber pads embedded in their moving parts, and the damping of the rubber pads is used to consume the vibration energy of the conductors, thereby damping the vibration of the conductors.

[0003] When installing the spacer bar, it is necessary to use an installation wrench to tighten and fix the parts on both sides. When fixing the spacer bar, the commonly used wrench drives the parts on both sides to tighten and fix by rotating the thread, which is slow and inconvenient to install. Utility Model Content

[0033] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a lever-type spacer wrench of the utility model in conjunction with the accompanying drawings.

[0034] like Figure 1-Figure 9As shown, an embodiment of the utility model provides a lever-type installation spacer wrench, including a traction rod 100 for traction installation of parts, a pressure rod 200 for lifting the traction rod 100 is installed on the upper end of the traction rod 100, a fixing section 300 for positioning the parts is sleeved on the upper end of the traction rod 100, a pin portion 400 for snap-fitting installation with the parts is movably installed on the lower end of the traction rod 100, the pin portion 400 is rotatably installed on the lower end of the traction rod 100, and a connecting rod portion 500 for supporting the pressure rod 200 is movably installed on the lower end of the pressure rod 200.

[0035] The upper end of the traction rod 100 is fixedly mounted with a mounting head 120 for mounting a pressure rod 200. The ends of the pressure rod 200 are movably mounted on both sides of the mounting head 120 through bearings. The connecting rod portion 500, the pressure rod 200 and the traction rod 100 arranged on the side of the fixed section 300 are arranged in a triangle shape.

[0036] Connecting ears 310 for installing the connecting head 540 are fixedly arranged on both sides of the fixing section 300. The connecting head 540 is movably installed inside the connecting ears 310. The upper end of the connecting head 540 is clamped on both sides of the connecting hole 210 arranged at the lower end of the pressure rod 200 and fixed by a mounting pin.

[0037] First, the end of the traction rod 100 and the bayonet portion 400 are penetrated through the middle of the part to be clamped, and the fixed section 300 and the bayonet portion 400 are pressed against one side of the part to be clamped. Then the pressure rod 200 is pressed downward, and the fixed section 300 and the connecting rod portion 500 remain stationary as a lever. The pressure rod 200 drives the traction rod 100 to rise upward, and the bayonet portion 400 at the end of the traction rod 100 approaches and presses against the other side of the part to be clamped during the rising process. Finally, the fixed section 300 and the bayonet portion 400 are shortened in distance to clamp the part to be clamped together, thereby completing the installation and clamping of the part. By utilizing the principle of leverage, the effect of clamping the part is achieved by pressing down the pressure rod 200, and the installation of the parts is fast, labor is saved, and the structure is simple.

[0038] The pressing rod 200 at the end of the traction rod 100 can be set to a single-sided type or a symmetrical double-sided type, which is convenient for the pressing operation of the parts and flexible to choose.

[0039] The lower end of the traction rod 100 is provided with a plurality of installation grooves 110 for installing the bayonet part 400. Both sides of the installation grooves 110 are provided with installation holes 150 for fixing the bayonet part 400. The installation position of the bayonet part 400 can be adjusted according to the thickness of the parts, which is more flexible to use.

[0040] One side of the mounting hole 150 can be configured as a hexagonal groove for easy fixation, and a hexagonal nut 130 can be embedded in the interior of the hexagonal groove. A bolt 140 for fixing the bayonet portion 400 is installed on the internal thread of the hexagonal nut 130. The bolt 140 passes through a through hole 420 opened in the middle of the bayonet portion 400 to be connected to the hexagonal nut 130. The hexagonal nut 130 can be effectively stored and limited by being embedded in the hexagonal groove. After the bolt 140 is installed and fixed, it is convenient for the bayonet portion 400 to pass through the center of the part installation.

[0041] Extension parts 410 for expanding the force-bearing area of ​​the pin part 400 are movably installed on both sides of the pin part 400. The extension parts 410 include an extension frame 411 movably installed inside the pin part 400 for extension and a telescopic rack 413 installed at one end of the extension frame 411 for driving the extension frame 411 to move. The telescopic rack 413 adjusts its position through an adjusting gear 415 meshingly installed in the middle, and is reset by traction of a reset spring installed on one side of the extension frame 411.

[0042] When the bayonet portion 400 is attached to the part to be fixed, the extension frame 411 on one side can be pulled to extend from the inside of the bayonet portion 400, thereby expanding the area of ​​the bayonet portion 400 fixing the part and avoiding the situation where it is inconvenient to fix the part due to the large center hole of the part.

[0043] An anti-skid pad 412 for preventing sliding is fixedly arranged on the upper surface of one side of the extension frame 411. The anti-skid pad 412 can be made of elastic rubber material. The upper surface of the anti-skid pad 412 can be arranged in a wavy shape, which makes it more convenient to make the upper surface of the extension frame 411 fit the parts to be fixed. The anti-skid pad 412 can prevent the extension frame 411 from sliding, thereby improving the part fixing effect.

[0044] An adjusting portion 440 for fixing the adjusting gear 415 is movably mounted on the upper end of the latch portion 400. The adjusting portion 440 includes a ratchet 441 fixedly mounted on one side of the adjusting gear 415 for positioning the adjusting gear 415 and a pawl 442 mounted on one side of the ratchet 441 for engaging and positioning the ratchet 441. One end of the pawl 442 is rotatably mounted in a cavity opened in the middle of the latch portion 400 through a torsion spring. A traction rope 443 for driving the pawl 442 to rotate is movably mounted on one side of the upper end of the pawl 442, and one end of the traction rope 443 is arranged outside the latch portion 400.

[0045] When the extension frame 411 is pulled out for fixing, after being pulled out to a specified length, the ratchet 441 and the pawl 442 engage with each other, thereby fixing the ratchet 441, and the adjustment gear 415 fixedly installed on one side is fixed, thereby preventing the extension frame 411 from rebounding. When the extension frame 411 needs to be retracted, the button at one end of the traction rope 443 is pulled, thereby driving the pawl 442 to rotate, and the reset spring drives it to reset, and the operation is simple.

[0046] A first locking hole 414 for fixing the extension frame 411 is provided at the lower end of the extension frame 411, and second locking holes 430 matching the first locking hole 414 are provided on both sides of the pin portion 400. The first locking hole 414 and the second locking hole 430 can be passed through an installation pin to fasten the extension frame 411. After the extension frame 411 is pulled to a specified position, the second locking hole 430 can be passed through an installation pin to fasten the extension frame 411, thereby fixing the position of the extension frame 411 to avoid severe wear of the ratchet 441 and the pawl 442 and protect the parts.

[0047] The connecting rod portion 500 includes a first support rod 510 and a second support rod 520 for supporting and fixing the pressure rod 200. Connectors 540 are installed at both ends of the first support rod 510 and the second support rod 520. The second support rod 520 is movably inserted into the cavity of the first support rod 510. An adjusting ring 530 is movably installed on one side of the end of the first support rod 510 through a bearing. A thread is provided inside the adjusting ring 530, which matches the thread arranged on the upper end of the second support rod 520. When the connecting rod portion 500 is used for support, the second support rod 520 can be extended from the inside of the first support rod 510 by rotating the adjusting ring 530, thereby extending the length of the connecting rod portion 500, which is convenient for adjustment according to the condition of the parts and more flexible to use.

[0048] The fixed joint 300 is movably installed with a ball 320 for moving the fixed joint 300. The ball 320 is installed outside the outer surface of the traction rod 100 to facilitate the traction rod 100 to slide up and down inside the fixed joint 300. The ball 320 can reduce the contact area and reduce the wear of parts.

[0049] Positioning grooves 160 for positioning the traction rod 100 are evenly provided on the upper end of the traction rod 100. A rotating clamp 330 for matching and engaging with the positioning groove 160 is provided on one side of the fixed section 300. The rotating clamp 330 is movably installed in the slot opened inside the fixed section 300 through a torsion spring. When the traction rod 100 moves upward, the rotating clamp 330 retracts and buckles the positioning groove 160 to prevent the traction rod 100 from retreating, thereby facilitating the movement of the traction rod 100.

[0050] The working principle of a lever-type installation spacer wrench is as follows: first, the end of the traction rod 100 and the bayonet portion 400 are penetrated through the middle of the part to be clamped, the fixed section 300 and the bayonet portion 400 are pressed against one side of the part to be clamped, and then the pressure rod 200 is pressed downward, the fixed section 300 and the connecting rod portion 500 are kept stationary as a lever, and the pressure rod 200 drives the traction rod 100 to rise upward, and the bayonet portion 400 at the end of the traction rod 100 approaches and presses against the other side of the part to be clamped during the rising process, and finally the fixed section 300 and the bayonet portion 400 are shortened to clamp the part to be clamped together, thereby completing the installation and clamping of the part, utilizing the lever principle, and by pressing the pressure rod 200 downward to achieve the effect of clamping the part, the installation speed of the part is fast, physical effort is saved, and the structure is simple.
