Comprehensive maintenance equipment used for rail transit

Abstract

The invention relates to the technical field of rail maintenance devices, in particular to comprehensive maintenance equipment used for rail transit. The equipment comprises a cart, a lifting module is fixedly connected to the top face of the cart, a bottom plate is fixedly connected to the output end of the lifting module, a working mechanism is arranged at the two ends of the bottom plate, and the working mechanism comprises a first sleeve pipe. In the equipment, brush plates, a nut sleeve and a rust removal rod are arranged, a nut is in clamped connection and screwed off through the nut sleeve, a second sleeve pipe drives the nut sleeve and the nut to move upwards, so that the rust removal rod is inserted into the nut, first reset springs extrude the brush plates to move downwards along sliding rails, the three brush plates move to the bottom ends of the sliding rails, a driving motor drives the first sleeve pipe to rotate, the outer side of a screw rod is brushed and subjected to rust removal through the brush plates, the nut rotates to rub with the rust removal rod, and therefore threads on the inner wall of the nut are brushed and subjected to rust removal, the manual workload is reduced, the working burden is relieved, and the thread part of the nut and the thread part of the screw rod are subjected to rust removal well.

Description

Background technique [0002] The rails are spliced ​​together by steel rails, and the rails are fastened to the road sleepers through the fasteners on both sides of the rails. After the rails run for a long time and vibrate, the nuts on the fasteners will loosen, and the rails cannot be effectively fixed. , and the fasteners are completely exposed to the disintegration environment, and the bolts are easily corroded, which weakens the strength. Therefore, it is necessary to regularly overhaul the bolts on the fasteners on both sides of the rail.

Problems solved by technology

[0002] The rails are spliced ​​together by steel rails, and the rails are fastened to the road sleepers through the fasteners on both sides of the rails. After the rails run for a long time and vibrate, the nuts on the fasteners will loosen, and the rails cannot be effectively fixed. , and the fasteners are completely exposed to the disintegration environment, the bolts in them are easily corroded, making the strength weaker, so it is necessary to regularly overhaul the bolts on the fasteners on both sides of the rail

[0003] When overhauling fastener bolts, first rotate the nut, then clean and derust the threaded part of the screw and nut, then re-tighten the nut, and brush the anti-rust grease on the bolt. The whole process generally takes three to five It is done by division of labor, and the required tools include torque wrench, grinder, steel brush, derusting knife, etc., which is time-consuming and labor-intensive, and it is troublesome to derust the threaded part of the nut and screw
