Abstract

The invention discloses a stable walking hydraulic stud wrench comprising soft rail clamping walking wheels. A middle plate and a wheel frame are arranged inside an adjusting seat; a guide post is arranged between the middle plate and the wheel frame which are capable of moving along the guide post vertically; a locking handle penetrates the adjusting seat and the middle plate sequentially; a spring sleeve the lower portion of the locking handle and is located between the middle plate and the wheel frame; the lower end of the wheel frame is provided with a bottom walking wheel; side connecting arms are arranged on two sides of the upper portion of the adjusting seat symmetrically; the external ends of the side connecting arms are hinged to the side connecting rods respectively; the lower ends of the side connecting rods are provided with side assistant wheels; a frame installation part is arranged at the lower end of the adjusting seat; two ends of the frame installation part are hinged to the middle of the corresponded side connecting rods; during operation, the bottom walking wheel contacts with the upper surfaces of rails, and the two side assistant wheels are arranged at the left and right sides of the rails. The wrench is capable of walking on the rails stably.

Description

technical field [0001] The invention relates to a hydraulic stud bolt wrench with good running stability on rails and stable walking. Background technique [0002] The YLB-750 hydraulic stud wrench with stable walking produced by Suzhou Luyun Electromechanical Equipment Co., Ltd. is an efficient and high-precision equipment for the construction and maintenance of sleeper nut fasteners. This machine is powered by imported American Briggs & Stratton gasoline engine. Driven and precisely controlled by a hydraulic system, it is a very suitable construction and maintenance machine for new and old railway lines, especially high-speed railway lines. [0003] main feature: [0004] 1. Realize the real hydraulic static torque to tighten the nut, and it is very convenient to adjust the size of the torque steplessly. The torque meter visually displays the tightening torque value, and the output torque is accurate and constant. [0005] 2. Automatically switch the tightening speed a...
