Abstract
The utility model relates to a railway track thermit welding tool and particularly relates to a sand mold lateral template used for railroad turnout steel rail thermit welding. The lateral template is divided into two parts from the middle in the longitudinal direction, so as to form two lateral templates, and a locking clamp is arranged between the two lateral templates. The sand mold lateral template provided by the utility model mainly solves the technical problem that the mounting and the dismounting are very difficult when thermit welding operation is performed on the railroad turnout of a universal sand mold lateral template (particularly the tip of the turnout ), sand mold mounting and dismounting operations in thermit welding can be performed on the tip of the turnout conveniently, and the thermit welding operation efficiency to the tip of the turnout can be improved greatly.
Description
Technical field
The utility model relates to railway track exothermic welding instrument, particularly a kind of track switch rail aluminothermy welding sand mold side template that is used in.
Background technology
19th-century latter stage, along with the development of metallurgical industry and chemical industry, people invent exothermic welding and come welded rails.Twentieth century begins to adopt exothermic welding to weld tramway railway and subway line abroad.Last century early sixties, China begins on railway to adopt exothermic welding to weld continuous welded rail track.
The rule of the cast of rail exothermic welding and cooling procedure and casting is very similar, so exothermic welding also is called cast welding.The exothermic welding sand mold needs accurately location, and is fixed in the steel rail welding line centre position firmly as moulding mold important in the cast welding process in welding process, to guarantee carrying out smoothly of exothermic welding.
Generally speaking, the straight rail that is used in that exothermic welding is a large amount of welds, and the installation of sand mold side template and dismounting have enough spaces to operate.
On track switch, when especially the exothermic welding operation was carried out at the switch blade position, because its operating space is quite narrow, general general sand mold side template was very difficult in the installation and the dismounting of this position; Though very can install reluctantly sometimes, after the aluminothermy welding is accomplished, but can't the sand mold side template be disassembled smoothly.
The utility model content
The purpose of the utility model is to provide a kind of track switch rail aluminothermy welding sand mold side template that is used in; It mainly solves general sand mold side template (especially switch blade position) on track switch and installs and dismantle very difficult technologies problem when carrying out the exothermic welding operation; It can carry out exothermic welding very easily at the switch blade position of track switch sand mold installation and field-strip have improved the exothermic welding operating efficiency at switch blade position greatly.
The utility model solves the problems of the technologies described above the technical scheme that is adopted.
A kind of track switch rail aluminothermy welding sand mold side template that is used in, it is characterized in that: this side template longitudinally is divided into two from the centre, forms two halves sheet side template, is provided with locking fixture between the two halves sheet side template.
The beneficial effect of the utility model is.
The utility model is under the prerequisite of the monnolithic case structure that does not change sand mold and other exothermic welding instruments; Re-design a slice detachable side template; Just can carry out the sand mold of exothermic welding very easily at the switch blade position of track switch and install and field-strip, improve the exothermic welding operating efficiency at switch blade position greatly.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
See also Fig. 1, the utility model discloses a kind of track switch rail aluminothermy welding sand mold side template that is used in.As shown in the figure: this side template 1 longitudinally is divided into two from the centre, forms two halves sheet side template, is provided with locking fixture 2 between the two halves sheet side template, therefore, has formed a kind of detachable side template.
Concise and to the point order is installed and dismantled to the sand mold 3 at the switch blade position of the utility model detachable side template as follows.
A., the base plate template is installed.
B. the switch blade outside (partly) sand mold 3 and side template 1 are installed.
C. two halves sheet side template is fixed (partly) sand mold with special-purpose locking fixture 2, be installed in the switch blade inboard.
D. other normal running operations of exothermic welding.
E. unclamp special-purpose locking fixture 2, take two halves sheet side template away from two side directions.
In sum, being merely the preferred embodiment of the utility model, is not the practical range that is used for limiting the utility model, and promptly all equivalences of doing according to the content of the utility model claim change and modify, and all should be the technological category of the utility model.
