Abstract
The utility model provides an under-well vertical-curve rail-bending machine, belonging to the mining rail apparatus field. The machine comprises a base, bearing arms and a hydraulic system. The utility model is characterized in that the hydraulic system is vertically fixed in the middle of the base; one bearing arm is respectively arranged on two sides of the hydraulic system and the bearing arms are vertically fixed on the base; round holes are equally cut on two horizontal bearing arms on the top of the hydraulic system. Compared with the prior art, the rail-bending machine has simple structure as shaft structure and other components are omitted and the integration is realized, so as to better enhance the mechanical strength for the bending operation of various light rails and heavy rails. And the operation of the machine is convenient so as to reduce the labor intensity of operators and enhance working efficiency, and the machine is also solid and durable.
Description
1, technical field
The utility model relates to the apparatus that the crooked rail used in a kind of mine is used, and specifically a kind of down-hole vertical curve is bent the rail working rig.
2, background technology
The route on turnout, mine has certain requirement to rail, all needs usually rail is carried out buckling work, carries out the laying of turnout rail after the rail bending.The instrument of present crooked rail has generally adopted structure or the modular construction of some, and this has just weakened its mechanical strength to a certain extent, but also has because the limiting factor first order buckling of equipment itself is not thorough.This brings very inconvenient factor for the bending work of rail.
3, summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, provides a kind of down-hole vertical curve to bend the rail working rig.
The technical solution of the utility model realizes in the following manner, this down-hole vertical curve is bent the rail working rig, comprise base, support arm, hydraulic system, it is characterized in that hydraulic system is vertically fixed on the centre of base, the hydraulic system both sides respectively are provided with a support arm, support arm is vertically fixed on the base, and hydraulic system comes directly towards on two horizontal support arms and has circular hole uniformly.
The utility model has the advantages that: the curved rail working rig of this down-hole vertical curve is simple in structure, omit the design of axle construction and other modular construction, realized integrated, thereby improved mechanical strength more, can bend the rail operation dissimilar light rails and heavy rail, easy to operate, alleviate operator's labour intensity, increase work efficiency, long service life has good value for applications.
4, description of drawings
Accompanying drawing 1 is the structural representation of the curved rail working rig of this down-hole vertical curve;
Accompanying drawing 2 is side views of the curved rail working rig of this down-hole vertical curve.
Mark in the accompanying drawing is represented respectively;
5, the specific embodiment
Below in conjunction with accompanying drawing vertical curve curved rail working rig in down-hole of the present utility model is done following detailed description the in detail:
Shown in accompanying drawing 1,2, down-hole of the present utility model vertical curve is bent the rail working rig, comprise base 1, support arm 2, hydraulic system 3, it is characterized in that hydraulic system 3 is vertically fixed on the centre of base 1, hydraulic system 3 both sides respectively are provided with a support arm 2, support arm 2 is vertically fixed on the base 1, and hydraulic system 3 comes directly towards on two horizontal support arms 2 and has circular hole 4 uniformly.
The support arm on hydraulic system both sides equates to the distance of hydraulic system jackshaft.
The upper end of support arm is a circular arc.
Circular hole quantity on the support arm is 2～5.
Two circular holes that have on the support arm of the curved rail working rig of this down-hole vertical curve are separately positioned on horizontal above and below, hydraulic system top.Treat crooked rail for one section during operation, carry out buckling work by uppermost two circular holes earlier,, can extract out if can reach bending effect; Carry out second order buckling processing again for crooked rail, it wants crooked curvature estimation earlier, rail is passed other circular hole rail is continued buckling work, wants crooked effect up to reaching.According to the complexity of mine geographic factor, can calculate the maximum curvature and the minimum curvature of required rail, thereby can also design the circular hole position on the support arm of this curved rail working rig as required.
