Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further:
See Fig. 1-Fig. 2, it is structural representation of the present utility model, a kind of grooved rail of the utility model hydraulic rail bender, comprise power set 5, hydraulic system, jim crow bearing 4 and gib head 2, described power set 5 are connected by cable with the motor 7 of hydraulic system, the hydraulic cylinder 6 of hydraulic system is fixed in the middle part of jim crow bearing 4, and gib head 2 is removably mounted on jim crow bearing 4 both sides.
Described power set 5 are gasoline engine generator or diesel-driven generator.
Described hydraulic system is made up of motor 7, hydraulic oil container 9, gear pump and hydraulic cylinder 6, motor 7 is fixedly connected with gear pump, and gear pump is arranged in hydraulic oil container 9, and hydraulic oil container 9 is by pipeline connection hydraulic cylinder 6, pipeline is established pressure meter 12, hydraulic oil container 9 is established operation control lever 8.
Described gib head 2 is fixed on jim crow bearing 4 by bearing pin 3, is provided with cushion block 10 between gib head 2 and institute's curved groove type rail 1.
Described jim crow bearing 4 bilateral symmetry arranges several pin shaft hole 11, establishes travelling wheel 13 bottom jim crow bearing 4.
The operating principle of a kind of grooved rail of the utility model hydraulic rail bender is: provide power supply by power set 5 (gasoline or diesel-driven generator), motor 7 driven gear pump is to hydraulic system fuel feeding, hook rail 1 with two gib heads 2 and be connected with jim crow bearing 4 with bearing pin 3, when pump oil loads, hydraulic cylinder 6 piston rod promotes rail 1 at middle part, make it produce elastic deformation, until plastic strain, reach straightening or bending object.
Following examples are implemented under premised on technical solutions of the utility model, give detailed embodiment and concrete operating process, but protection domain of the present utility model are not limited to following embodiment.In following embodiment, method therefor is conventional method if no special instructions.
[embodiment 1]
The present embodiment power set 5 adopt gasoline engine generator SC700T (rated power: 6500W; Rated speed: 3000rpm); Motor 7 is threephase asynchronous Y112M-6; Rated power: 2.2kW;
Hydraulic system rated pressure: 60MPa flow: 60L/min; Specified curved rail (straight rail) power: 105T; Impulse stroke: 100mm; Hydraulic oil adopts 46# antiwear hydraulic oil; Hydraulic oil container 9 volume 40L;
Jim crow bearing 4 and gib head 2 adopt 25mm steel plate to be welded, and tensile strength is high.
Complete machine weight 150kg.
Be provided with overflow valve in hydraulic system, when system nominal pressure ± 3MPa, overflow valve is opened.Jim crow is when specified straight rail power, and pressurize 3min, oil pressure declines and is less than 3mpa.
Described in the present embodiment, grooved rail hydraulic rail bender using method is as follows:
Check before work that whether fastening whether each several part part is intact, connect, hydraulic oil container 9 whether oil starvation, and generator 5 gases up.Normally whether start gasoline engine generator 5 and motor 7, observe and to run, pull operation control lever 8, confirm that hydraulic cylinder 6 is under immunization with gD DNA vaccine, piston rod stretches out or resets steadily.
Grooved rail 1 is paved with backing plate 14 and puts smooth, adjustment jim crow bearing 4 height, ensures that hydraulic cylinder 6 piston rod ejects position concordant with grooved rail 1 horizontal center line.
Gib head 2 is hooked grooved rail 1 and be positioned at the both sides that hydraulic cylinder 6 piston rod ejects position, rail 1 upper surface is close in gib head 2 bottom surface, with bearing pin 3, gib head 2 is fixed in the pin shaft hole 11 of jim crow bearing 4 correspondence, and cushion block 10 is filled in eject between the opposite side gib head 2 of position and the web of the rail at hydraulic cylinder 6 piston rod, after piston rod withstands web of the rail centre position, jim crow bearing 4 is locked on rail 1.Pull operation control lever 8, Slow loading, hydraulic cylinder 6 piston rod stretches out and rail 1 is deformed.After one place has exerted pressure, promote jim crow bearing 4 and slide on rail 1, eject pressurization once at interval of 200mm hydraulic cylinder 6 piston rod.Be close to inside track with arc model, until curved in tracks arc meets designing requirement simultaneously.
After having worked, extract bearing pin 3, take off cushion block 10, unload gib head 2.Check whether each position permanent deformation and other anomalies occur, with cleaning agent or pure industrial alcohol cleaning oil circuit, keep for next time.
When the utility model uses, can select suitable gib head 2 according to rail 1 model, select gib head 2 fixed range according to bend radius, pressure meter 12 can display system pressure, effectively prevents deflection excessive.Application the utility model, can reduce the labour intensity of workman, and efficiency improves more than 3 times than using leading screw jim crow.And track construction condition can be improved, be more suitable for the field operation environments such as mine, harbour, forest farm, traffic, light-duty, the curved rail of the level of heavy rail, vertical curve or straight rail operation can be solved simultaneously.
