Description

Technical Field

[0001] The invention relates to the technical field of assembly tools, in particular to a large screw tightening device for a concrete sleeper turnout. Background Art

[0002] The large screws of the concrete sleeper turnouts are oxidized by the external environment for a long time and rusted in the nylon sleeve. This situation is quite common, especially the large screws on the straight outer side and the guide bend of the turnout, which account for about 65% of the entire turnout. When loosening the large screws of the turnout on site, the following three problems are often encountered: First, the torque of most large screws on site far exceeds the maximum torque of the currently equipped electric wrenches. According to on-site tests, the maximum torque of large screws can reach 7000N.M. It is difficult to loosen them using existing electric wrenches, and forced use can easily cause damage to the electric wrenches. Second, it is time-consuming, labor-intensive and inefficient. At present, when encountering large screws that are corroded and cannot be loosened, the original manual "push grinding" method is usually used, and 5-7 people are arranged to use T-type screwdrivers to loosen large screws, which is not only very laborious, but also inefficient; Third, there are hidden dangers to personal safety. When using a T-shaped screwdriver manually, crowbars need to be inserted at both ends of the T-shaped screwdriver handle to increase the length of the screwdriver arm. There are many operators concentrated in the operation, and the torque is difficult to control, which can easily cause the screwdriver to deform, slip, or even break due to excessive torque. Large screws are also often suddenly twisted off, posing a personal safety hazard.

[0003] For this reason, a large screw tightening device for concrete sleeper turnout is now proposed to solve the above-mentioned problem. Summary of the invention

[0026] The main research contents of the turnout large screw super torque tensioner are as follows: 1. The electric wrench motor and reducer are adapted to determine the reduction ratio; select the torque size of the reducer according to the torque size of the electric wrench to ensure that the reducer can provide sufficient torque support for the wrench. Different reduction ratios will bring different speeds and torque outputs. On-site testing should be carried out to select the appropriate reduction ratio according to actual needs.

[0027] 2. Determine the appropriate lithium battery capacity based on the workload on site; after selecting the model of the electric wrench, use the formula P=UI based on the rated power of the selected electric wrench to obtain the electric wrench current I=P / U, select the skylight time of 180 minutes, and use the power Q=It to calculate the required battery capacity.
