Description
Technical field
The utility model relates to a kind of railway maintenance instrument, and more particularly, it relates to a kind of acclerating road switch slide plate hydraulic pin remover.
Background technology
In order to adapt to the needs of railway transportation high-speed overload development, railway speed increase circuit upgrades year by year lays various types of acclerating road switch, the train of high-speed cruising can apply larger load and impact force to these track switches, the maintenance of acclerating road switch then becomes an important component part of railway speed increase works department routine work, and extracting slide plate pin is exactly one of operation related in the maintenance of acclerating road switch.
If on dismounting AT60 tongue slide plate when pin, other instruments, due to its narrow space, are inconvenient to dismantle, and therefore need the pin pulling tool of specialty.Existing application number be 200720142798.9 Chinese patent disclose a kind of pin removal, can fast and labour-saving pin is extracted, but needing to dismantle in the very serious pin process of some corrosions, the head of a nail due to pin top is difficult to be pullled energetically, therefore, this kind of instrument is difficult to effectively remove it.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is that providing a kind of can stablize the acclerating road switch slide plate hydraulic pin remover removing some corrosion pins.
For achieving the above object, the utility model provides following technical scheme: a kind of acclerating road switch slide plate hydraulic pin remover, comprise hydraulic hand-pump, pin extraction mechanism, described pin extraction mechanism comprises the first working head, for clamping the pin pliers of pin, also comprise pin ejecting mechanism, described pin ejecting mechanism comprises the second working head, and described second working head is provided with and ejects screw rod, and described first working head is all communicated with hydraulic hand-pump by high-pressure hose with the second working head.
The utility model is set to further: described first working head and the second working head are double plunger pipe bending cylinder, and described pin pliers is positioned at the centre position of the first working head and in the same plane with the plunger of the first working head.
The utility model is set to further: described in eject screw rod and comprise screw rod and swivel nut, swivel nut is connected with screw flight, and screw rod is fixed on the second working head and fixed point is positioned at the side of the second working head away from plunger.
Compared with prior art, the utility model has the advantage of, increase extra on architecture basics pin ejecting mechanism is extracted what originally extracted, when dismounting pin, while utilize pin pliers to extract, while utilization ejects screw rod, pin is ejected, make the active force acting on pin add one times, meet job requirements.The machine has the features such as compact conformation, fitting operation convenience, reasonable stress, long service life.

Detailed description of the invention
Referring to figs. 1 through Fig. 3, the utility model acclerating road switch slide plate hydraulic pin remover embodiment is described further.
A kind of acclerating road switch slide plate hydraulic pin remover, comprises hydraulic hand-pump 1, pin 5 extraction mechanism, pin 5 ejecting mechanism.Described pin 5 extraction mechanism comprises the first working head 21, for clamping the pin pliers 22 of pin 5, first working head 21 is double plunger pipe bending cylinder, double plunger pipe bending cylinder is connected by high-pressure oil pipe with hydraulic hand-pump 1, it has two movable plungers, in the same plane with plunger for the centre position of fixing pin pliers 22 plunger.
Described pin 5 ejecting mechanism also comprises the second working head 31, second working head 31 is also double plunger pipe bending cylinder, first working head 21 is all connected with hydraulic hand-pump 1 by high-pressure oil pipe with the second working head 31, and hydraulic hand-pump 1 drives the plunger motion of the first working head 21 and the second working head 31 simultaneously when work.Second working head 31 is provided with and ejects screw rod, and described first working head 21 is all communicated with hydraulic hand-pump 1 by high-pressure hose 11 with the second working head 31.
Wherein, described in eject screw rod and comprise screw rod 32 and swivel nut 33, described screw rod 32 one end is connected with described second working head 31, and described screw rod 32 other end is connected with described swivel nut 33, and as shown in Figure 1, screw rod 32 is positioned at the side of the first working head 21 away from plunger in position.Because the second working head 31 is double plunger pipe bending cylinders, its plunger eject apart from limited, therefore its disposable pin 5 ejected is apart from limited.After ejecting pin 5 one segment distance, plunger reaches range, now handles plunger retraction, and then rotate swivel nut 33 and adjust long by the whole screw rod that ejects, the pin 5 until swivel nut 33 is conflicted, plunger conflict sleeper 4, again handles plunger and stretch out.And so forth, just longer pin 5 can be ejected from sleeper 4.Screw rod 32 should be as far as possible long with the threaded engagement length of swivel nut 33, realizes the whole larger adjustable range ejecting screw rod.
The whole pin removal course of work is as follows, first by pin pliers 22 inlay card of pin 5 extraction mechanism at pin 5 head, then pin 5 ejecting mechanism is placed between side sleeper 4, withstands pin 5 from afterbody.At this time operate hydraulic hand-pump 1, make the plunger motion of the first working head 21 and the second working head 31, one ejects one and extracts, and guarantees the pin 5 in slide plate to extract.Process is simple and convenient, opens oil return valve more afterwards, just can make two double plunger pipe bending cylinder plunger return, and internal construction such as the application number of double plunger pipe bending cylinder is open in the patent of 200720142798.9.
Its acclerating road switch slide plate hydraulic pin remover also has a kind of usage, when needing pin 5 to squeeze into slide plate, first the head ejecting screw rod and pin 5 can be conflicted, then operating hydraulic hand-pump 1 drives the plunger of the second working head 31 to stretch out, pin 5 is squeezed into, this method of work not only can allow acclerating road switch slide plate hydraulic pin remover have the function of nail 5 of pulling pin, and also has the function squeezing into pin 5.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
