As shown in fig. 1, the hydraulic rerailer is shown in use with a dedicated support kit, comprising: the length of the supporting beam 1 is longer than the track gauge of the steel rail, and the supporting beam is mainly used for placing a hydraulic rerailer; the support beam 1 is transversely placed on two steel rails through two rail head cushion blocks 3, and one end of the support beam 1 and one rail head cushion block 3 form rotation constraint; the free end of the supporting beam 1 is adjusted in height by a hydraulic adjusting machine 2 so as to ensure that the hydraulic rerailer is in a horizontal state and smoothly finish rescue operation.
First, the support beam 1 is explained with reference to fig. 2 and 3. The support beam 1 spans over the two rail head cushion blocks 3, and is positioned at the middle part of the steel rail to bear the maximum bending moment, so that the middle part of the support beam is thickened to form a reinforcing part 12, and the whole support beam 1 is in a trapezoid step shape. Considering the situation that the derailment distance of the train is far and the roof is required to be restored from the outer side of the steel rail when the hydraulic rerailer is used for roof restoration rescue, and the situation that the horizontal state of the supporting beam 1 is required to be adjusted when the curve rescue is carried out. The supporting beam 1 is provided with a long supporting surface and a short supporting surface, the long supporting surface is a free end, the short supporting surface is a constraint end, the long supporting surface extends to the end position of the sleeper at the outer side of the steel rail, and the height is adjusted by the hydraulic adjusting machine tool 2 so as to ensure that the hydraulic rerailer is in a horizontal state for rescuing the situation. The supporting beam 1 is a key bearing part of the supporting device, the mechanical model of the supporting device is a simple supporting beam structure, the bearing condition is complex, and the supporting strength of the supporting beam is ensured and the self weight of the supporting beam is strictly controlled by reasonably designing the bearing structure.
In this embodiment, the support beam 1 and the head block 3 are rotationally constrained by a shaft structure. The two sides of a rail head cushion block 3 are respectively fixedly connected with a rotating shaft seat 4, and one side of a short supporting surface of the supporting beam 1 is provided with a rotating shaft 11, so that the supporting beam 1 and the rail head cushion block 3 are in rotating connection after being installed.
Next, the head block 3 will be described with reference to fig. 2 and 5. The rail head cushion block 3 is mainly used for protecting the rail head of a steel rail, expanding the supporting area of the supporting beam 1 and avoiding bearing damage caused by the line contact between the supporting beam 1 and the top surface of the steel rail. The steel rail is designed by adopting a profiling structure, is closely placed at the head part of a steel rail, and is provided with a supporting beam 1. Meanwhile, the height of the free end of the supporting beam 1 is required to be adjusted when the rescue of the curve superelevation road section is considered, so that the supporting beam 1 is in a horizontal state, and the situation of line contact with larger bearing risk is avoided in order to ensure that the rail head cushion block 3 and the supporting beam 1 are constantly kept in surface contact in the height adjustment process. The rail head cushion block 3 adopts a combined structural design, and comprises a first supporting piece 31 and a first rolling piece 32, wherein the first supporting piece 31 and the first rolling piece 32 can roll relatively so as to ensure that the rail head cushion block 3 and a steel rail have angle adjustment freedom degree. The first support 31 is in direct contact with the support beam 1 and is dimensioned to fit the width of the support beam 1, ensuring a sufficient bearing area. The first rolling element 32 adopts an arch structure design (U-shaped structure), and because the first rolling element is mainly buckled on the rail head of the steel rail, the contact surface is required to be matched with the rail head to carry out special curved surface design, the first rolling element 32 and the rail head of the steel rail are ensured to be in surface contact at the moment, the bearing capacity is ensured, and the top surface of the steel rail is prevented from being damaged. The first rolling member 32 is accommodated by providing a concave arc-shaped groove on one side surface of the first supporting member 31. When in use, in order to adjust the supporting beam 1 to the horizontal, the horizontal included angle of the supporting beam 1 needs to be changed in real time, and as the first supporting piece 31 is in real-time surface contact with the supporting beam 1, the first supporting piece 31 and the first rolling piece 32 can rotate relatively, so that the first supporting piece 31 and the first rolling piece 32 keep in real-time surface contact, and the bearing capacity of the rail head cushion block 3 is improved.
In actual production, considering field operation efficiency and equipment transportation convenience, the width of the rail head cushion block 3 should be comprehensively designed, and the weight bearing area and the weight bearing capacity should be ensured and simultaneously the weight bearing capacity should be lighter as much as possible.
