Abstract
The utility model relates to a bestriding-type hydraulic hole opener for hole punching operation of a steel rail. The hole opener comprises an oil pump, an oil pipe, a casing capable of accommodating the steel rail and provided with a hollow cavity, an oil cylinder installed in the casing, a piston and a piston rod arranged in the oil cylinder, a hole-squeezing male die on one side of the hollow cavity, a hole-squeezing female die on the other side of the hollow cavity, and a discharging hole, wherein the hole-squeezing male die is installed at the front end of the piston rod; and the center lines of the piston rod, the hole-squeezing male die and the hole-squeezing female die are collinear. The hole opener is characterized in that the hollow cavity is positioned in the middle of the casing and opened on the lower end surface of the casing. The hole punching operation of the installed steel rail can be conveniently carried out by the hole opener, so that the application range of the hole opener is wider.
Description
Technical field
the utility model relates to and a kind of rail is carried out the saddle ride type hydraulic opener of drilling operation, relates to the hydraulic tool technical field.
Background technology
In the prior art, the hydraulic opener that rail is carried out drilling operation by the bottom have the body of the cavity that can hold rail, the oil pump that is installed on the body internal upper part, oil pipe, oil cylinder, be located at oil cylinder inner carrier and piston rod, through lever link to each other with piston rod be installed on bottom in the body and be positioned at the crowded hole formpiston of cavity one side, crowded hole former, the discharge opening that is positioned at the cavity opposite side constitutes.During work, the motion of oil cylinder piston bar is squeezed the hole formpiston through lever pushing the rail that is positioned at cavity is carried out drilling operation.The hydraulic opener machine volume of this structure is big, Heavy Weight, operation inconvenience; The lever bearing capacity is big, and lever and body stage casing are fragile.For this reason; Chinese patent CN201659199U discloses hydraulic opener; It comprises oil pump, oil pipe, have the body of the cavity that can hold rail, be installed on oil cylinder in the body, be located at in-oil cylinder piston and piston rod, be positioned at cavity one side crowded hole formpiston, be positioned at crowded hole former, the discharge opening of cavity opposite side; Said crowded hole formpiston is installed on the piston rod front end, and piston rod, crowded hole formpiston, crowded hole former three's center line is on same straight line.It has saved leverage, and body weight is light, volume is little, and is easy to operate, and body intensity is high.Its weak point is that it only is applicable to the perforate of uninstalled rail, can't carry out the perforate operation for mounted rail, and the scope of application is limited, need improve.
Summary of the invention
the utility model aims to provide the wideer saddle ride type hydraulic opener of a kind of scope of application.
The technical solution of the utility model is following:
a kind of saddle ride type hydraulic opener; Comprise oil pump, oil pipe, have the cavity that can hold rail body, be installed on oil cylinder in the body, be located at in-oil cylinder piston and piston rod, be positioned at cavity one side crowded hole formpiston, be positioned at crowded hole former, the discharge opening of cavity opposite side; Said crowded hole formpiston is installed on the piston rod front end; Piston rod, crowded hole formpiston, crowded hole former three's center line is characterized in that on same straight line: said cavity is positioned at the body middle part and is opened on the body lower surface.
this technical scheme can be carried out the perforate operation for mounted rail easily.
Further technical scheme is:
said crowded hole former is installed on the swivel nut front end, and the swivel nut spiral is connected in the body of cavity opposite side, the inner discharge opening that forms of swivel nut.
this technical scheme is convenient to regulate the distance of squeezing between hole former and rail, and is convenient to change crowded hole former.
Another improvements are:
The port of export of
said discharge opening is equipped with plug screw.
this technical scheme can prevent that the waste material of extruding from flying out, and guarantees safety.
another improvements are: on the said body carrying handle is installed.
Description of drawings
To combine accompanying drawing and embodiment that the utility model is explained further details below
.
accompanying drawing 1 is the structural representation of the utility model embodiment.
Each sequence number is respectively in
accompanying drawing 1: 1, joint; 2, piston; 3, seal; 4, oil cylinder; 5, body; 6, piston rod; 7, carrying handle; 8, cavity; 9, back-moving spring; 10, squeeze the hole formpiston; 11, rail; 12, squeeze the hole former; 13, discharge opening; 14, hexagonal swivel nut; 15, plug screw.
The specific embodiment
are referring to accompanying drawing 1; Saddle ride type hydraulic opener shown in the utility model embodiment; Be split-type structural; Constitute by separation oil pump (not drawing among the figure), oil pipe (not drawing among the figure), saddle ride type hydraulic opener body three parts outside; Comprise body 5 on the body, be installed on oil cylinder 4 in the body, be located at in-oil cylinder piston 2 and piston rod 6, be set in back-moving spring 9 on the piston rod 6, be positioned at the crowded hole formpiston 10 that is installed on piston rod 6 front ends of cavity 8 one sides, the spiral that is positioned at cavity 8 opposite sides is connected in the hexagonal swivel nut 14 of body, the crowded hole former 12 that is installed on hexagonal swivel nut 14 front ends, hexagonal swivel nut 14 middle parts have discharge opening 13, the port of export of discharge opening 13 is equipped with plug screw 15.Piston 2 is structure as a whole with piston rod 6, and carrying handle 7 is installed on the body.Above-mentioned cavity 8 is positioned at the body middle part and is opened on the body lower surface.
During
operation; The saddle ride type hydraulic opener is straddled on mounted rail, and turn hexagonal swivel nut 14 makes crowded hole former 12 be close to rail; The oil pipe (not drawing among the figure) that connects oil pump (not drawing among the figure) is sent into hydraulic oil in the oil cylinder 4 through joint 1; Promotion piston 2 pushes rail 11 with piston rod 6 motions, the crowded hole formpiston 10 that is installed on piston rod 6 front ends, and the center line of piston rod 6, crowded hole former 12, crowded hole formpiston 10, discharge opening 13 4 is on same straight line; Waste material under the extruding gets into discharge opening 13, and screwing off plug screw 15 can in time discharge waste material.
above-mentioned accompanying drawing and embodiment only are used to explain the utility model, and the protection domain of the utility model is not constituted any limitation.Under the inventive concept of the utility model, adopt any protection domain that replacement scheme has fallen into the utility model certainly that is equal to.
