Anti-falling digital-display torque wrench for aerial working

Abstract

The invention belongs to the technical field of appliances for aerial working, and discloses an anti-falling digital-display torque wrench for aerial working. The anti-falling digital-display torque wrench for aerial working is provided with a handle, wherein an anti-falling ring buckle sleeves outside the handle, a rear cover is spirally installed on the tail part of the handle, a power supply sleeves in the handle, and a force application rod sleeves outside the power supply; a ratchet wheel head is arranged at the front end of the handle, and a torque sensor is connected outside the ratchet wheel head; a display screen is installed at the middle part of the handle in an inlaying manner, and a control panel is installed in the display screen; and the signal output end of the torque sensor is electrically connected with the control panel through an electronic circuit board, and the control panel is electrically connected with the display. The anti-falling digital-display torque wrench for aerial working realizes setting and counting, measurement and recording for many preset target measurement values; and the fastening amount of each bolt of an iron tower and the corresponding torque value are effectively determined, and the counting workload and the error rate of working personnel on the tower are greatly lowered, so that the working efficiency is effectively increased, and the convenience is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of high-altitude work tools, and in particular relates to a digital display torque wrench for high-altitude work to prevent falling. Background technique [0002] At present, there are two types of torque wrenches: mechanical and electronic. The mechanical type includes preset type, fixed value type, meter type and pointer type. convenient. Most of the circuit part of the electronic torque wrench is composed of analog components. After the output signal of the sensor is amplified and A / D converted, it is sent to the display for display, and its measurement accuracy is low. In addition, there is also a torque wrench using a single-chip microcomputer, which has improved measurement accuracy and increased functions, but the structural design has no operating safety device, which cannot meet the needs of high-altitude operations. The operation mode and storage mode are relatively simple and can only meet the co...
