Description

Technical Field

[0001] The utility model relates to the technical field of sleepers, in particular to a cutting machine for sleepers. Background Art

[0002] Railway is the main artery of my country's national economic development. With the rapid development of my country's railway, the requirements for the stability of railway operation are getting higher and higher. The railway turnout area is used very frequently as a hub for train line change. At the same time, it is affected by the vibration of train passing, the creep of rails, and mechanical wear. Its failure rate is the highest in the railway system. When the train passes through the railway turnout area, due to the geometric shape of the turnout guiding the train from one track to another, it usually causes a large lateral force to act on the track system. This lateral force is mainly caused by the change in the direction of the train and the interaction between the wheels and the track. Under the long-term track vibration and large lateral force, the shoulder of the turnout sleeper is prone to damage, cracking and falling off, resulting in insufficient lateral resistance of the turnout track, affecting the operational safety of the train.

[0003] At present, there are mainly the following methods to repair the shoulder guard of existing sleepers: 1. Replace the sleepers. This method is labor-intensive and mainly relies on manual work. The operation is difficult and inefficient, and it consumes manpower and material resources; 2. Pouring repair materials directly on the damaged area. This method is simple and fast, but it has high requirements for repair materials and consumes a lot of funds. After most of the repair materials are repaired, it takes time to wait for the repair materials to completely solidify before the normal use of the sleepers can be restored, which greatly affects the normal operation of the site. When there are many pieces of fallen blocks on the shoulder guard, it is necessary to fill them in each fallen block area, which consumes a lot of time. Utility Model Content

[0040] (5) First, use a cleaning machine to clean the required cutting area of ​​the sleeper and remove excess slag and dust;

[0041] (6) After cleaning, install the cutting machine at the designed position, fix the first bracket 1 and the second bracket 2 by rotating the screw 31, and move the cutting machine to the position of the sleeper to be cut;

[0042] (7) Start the pusher 6 on the top of the first bracket 1 and the second bracket 2 to move the vertical cutting mechanism 4 to the vertical cutting position, start the first telescopic member 42 to make the cutting circular saw 44 start to vertically cut the designed position of the rail sleeper shoulder, and move the first telescopic member 42 left and right through the pusher 6 in the T-shaped slide groove 411, so that the cutting circular saw 44 finally completes the vertical cutting;

[0043] After the vertical cutting is completed, the first telescopic member 42 and the push member 6 in the T-shaped slide groove 411 are both paused;

[0044] Start the second telescopic member 53, adjust the laser cutter 54 to the transverse cutting position, and then start the pusher 6 on the top of the first bracket 1 and the second bracket 2, finally drive the laser cutter 54 to move forward and backward, and complete the transverse cutting of the sleeper shoulder until the designed sleeper shoulder is cut;

[0045] (8) When the designed shoulder guard is cut, turn off and remove the cutting machine, remove the old shoulder guard, and clean the broken stones and dust left by the cutting. After cleaning, place the prefabricated sleeper shoulder guard mark in the corresponding position;

[0046] (9) Then, screw steel nails are drilled into both sides of the new shoulder to securely connect it to the old sleeper;

[0047] (10) After the fixed connection is completed, concrete polymer compound repair material is injected into the gap between the new shoulder and the old sleeper for repair. At this point, all the repair steps of the sleeper shoulder are completed.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
