Description

Anti-twist torque multiplier wrench

technical field

The utility model relates to the field of tools, in particular to an anti-rolling torque multiplication wrench, which is used for tightening or disassembling an outer hexagonal bolt or other similar structures fastened by an outer hexagonal nut.

Background technique

Bolts and nuts are commonly used fasteners in daily life and production. They are widely used in various fields due to their simple manufacture and strong adaptability. However, when nuts and bolts are used to fasten workpieces, the phenomenon that the bolts rotate around the shaft often occurs, that is to say, the bolts will follow the rotation of the nuts. Especially after the bolts and nuts are rusted to death, the following phenomenon is particularly serious.

In order to prevent the bolt from rotating, the measure most people take is to use the upper and lower wrenches to twist in opposite directions to tighten or disassemble it. Moreover, it is necessary to lubricate the rusted bolts when they need to be removed, and even to remove some rusted bolts, it is necessary to use cutting tools to cut them, which has caused great troubles in daily production and life. . This problem becomes particularly prominent during high-altitude construction. For example, the porcelain insulators widely used in the process of wiring wires use a fastening structure of a screw rod and two outer hexagon nuts. These porcelain insulators are installed on the top of the pole to fix and insulate the wires. effect. Due to long-term exposure to the air, the fasteners of these porcelain bottles are easily rusted. When dismantling or repairing these porcelain insulators, since the construction site is at a high altitude, improper operation when using two wrenches may easily cause objects to fall from the height, and the cutting tools cannot reach the high altitude, so it is extremely difficult to remove these rusted porcelain insulators.

detailed description

Below in conjunction with embodiment the utility model is described in further detail:

As shown in Figures 1 and 3, the utility model is an anti-coupling torque multiplication wrench, which mainly includes a torque multiplier 2 and an anti-coupling mechanism installed on the torque multiplier 2 in the preferred embodiment .

The anti-heel rotation mechanism includes a connecting handle 4 installed on the torque multiplier 2, a trip beam 5 and an anti-heel rotation wrench 6. One end of the connecting handle 4 is hinged by a pair of side ears arranged on the side wall of the torque multiplier 2 and the torque multiplier 2, and a vertical trip beam 5 is installed at the other end, and an anti-following wrench is installed on the top of the trip beam 5 6.

Torque multiplier 2, also known as torque multiplier, torque amplifier, gear reducer, torque amplifier, force booster, etc., is a device that can increase torque for the operator. Torque multiplier 2 internally realizes torque amplification through a set of planetary gears. Since the output power will not exceed the input power, the rotation speed of the output shaft is lower than that of the input shaft. The common torque multiplier 2 currently on the market generally achieves torque multiplication through planetary gears, which can generally be amplified by 5 to 125 times, and the maximum output torque can reach about 50,000 Nm.

A rocking bar 1 is installed on the input shaft of the lower end of the torque multiplier 2 in the utility model, and a nut sleeve 3 is installed on the output shaft at the upper end. As shown in FIG. 4 , the nut sleeve 3 can use an inner hexagonal sleeve or an outer hexagonal sleeve or a torx sleeve according to different bolts. A pair of side ears for hinged connection with the connecting handle 4 are also arranged on the side wall of the torque multiplier 2 .

The anti-heeling wrench 6 of the present invention is connected with the tripping beam 5 through the jacking bolt B8, and the position of the anti-heeling wrench 6 can be adjusted at any time by adjusting the jacking bolt B8 during use, or the anti-heeling wrench 6 can be replaced. The anti-heeling wrench 6 in the utility model is a wrench with only one end opening. According to different usage conditions, different opening forms such as dull mouth, live mouth, and plum blossom mouth can be selected. Special tools such as pliers.

The trip beam 5 of the utility model is connected with the connecting handle 4 by the jacking bolt A7. One end of the connecting handle 4 is provided with a through hole which can be loosely matched with the trip beam 5, and the trip beam 5 is installed in the through hole and fastened by the tightening bolt A7. During use, the trip beam 5 and the connecting handle 4 can be loosened or tightened by adjusting the tightening bolt A7.

Used jacking bolt A7 and jacking bolt B8 in the utility model all can be outer hexagonal bolt, inner hexagonal bolt.

Illustrate working principle or using method of the present utility model below in conjunction with specific embodiment:

As shown in FIG. 1 , it is a structural diagram of the utility model for removing the porcelain insulator 9 ; FIG. 2 is a structural diagram of the porcelain insulator 9 . Porcelain bottle insulator 9 is a device fixed on the top of the utility pole for fixing and insulating electric wires. Porcelain bottle insulator 9 is fixed on the angle iron in the form of a screw rod plus a lower nut.

When the utility model is applied to remove the porcelain bottle insulator 9 fixed on the angle iron, firstly, different anti-heeling wrenches 6 and nut sleeves 3 should be selected according to different fasteners. Hex socket. After selecting a suitable nut sleeve 3 and anti-heeling wrench 6, adjust the position of the trip beam 5 by tightening the bolt A7, and adjust the distance between the anti-heeling wrench 6 and the nut sleeve 3 properly.

Then clamp the anti-following wrench 6 and the nut sleeve 3 on the upper and lower nuts of the porcelain insulator 9 respectively, and rotate the rocker 1. At this time, the outer wall of the torque multiplier 2 will rotate in the opposite direction with the rotation of the rocker 1. At the same time, it drives the connecting handle 4 to rotate in the opposite direction. When the trip beam 5 on the connecting handle 4 is caught by the angle iron on which the porcelain insulator 9 is installed, it starts to prevent the torque multiplier 2 from rotating in the opposite direction. The output shaft of the torque multiplier 2 of the rod 1 will transmit the amplified torque to the lower nut to rotate the lower nut. At the same time, since the anti-following wrench 6 has fixed the upper nut, the upper nut will not follow the phenomenon. Therefore, the lower nut will be gradually loosened under huge torque, and then the entire dismantling work will be completed.
