The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further.
As depicted in figs. 1 and 2, a kind of sleeper bolt hydraulic spanner comprises frame 1, in frame 1 bottom road wheel 2 is installed, and frame 1 rides on the rail 15 through former and later two travelling wheels.Height adjustment mechanism 14 is installed on road wheel 2, and the height adjustment mechanism 14 in the utility model is made up of upper and lower two spacers and a bolt that runs through two spacers, wherein goes up spacer and is connected with frame 1; Following spacer is connected with road wheel 2; Through regulating bolt, can regulate the distance between the upper and lower spacer, thereby reach the purpose of regulating distance between frame 1 and the road wheel 2; Realize the height adjusting of frame, to adapt to the rail height.In frame 1 bottom connecting rod 16 is installed also; Because rail 15 is normally left and right two on the sleeper; Therefore in use usually need be on another one steel rail with connecting rod 16 overlap joints; Make it form three strong points, play supporting role, make frame stable in the course of the work better like this frame with forward and backward road wheel.Explosive motor 3, duplex pump 4 and hydraulic actuating mechanism are installed on frame 1, and explosive motor 3 can be gasoline engine, and it can self power generation, to satisfy the field work demand.Said hydraulic actuating mechanism is made up of hydraulic pressure cooling system 51, solenoid directional control valve 52 and hydraulic motor 53; The output shaft of explosive motor 3 is connected to duplex pump 4 behind clutch 6, the fluid of duplex pump 4 outputs inputs to hydraulic motor 53 successively after 51 coolings of hydraulic pressure cooling system and solenoid directional control valve 52 switching-overs.On duplex pump 4, also be provided with piloted unload valve; Its role is to control the output pressure size of duplex pump 4; Can control the duty of whole hydraulic system through piloted unload valve, after the off-load of pilot-operated type unloader, whole hydraulic system is all out of service.Be fixed with gear-box 7 in the bottom of hydraulic motor 53; The upper end of quill 8 is installed in the gear-box 7 through bearing; In gear-box 7, be provided with intermeshing idle wheel 9 and sleeve shaft gear 10; Idle wheel 9 is installed on the output shaft of hydraulic motor 53, and sleeve shaft gear 10 is enclosed within on the quill 8, and the revolving force of hydraulic motor 53 outputs passes to quill 8 after idle wheel 9 and sleeve shaft gear 10; Be connected with sleeve assembly 11 at quill 8 lower end screw threads, the rotation of control sleeve assembly 11 during quill 8 rotations.Here the effect of sleeve assembly 11 is to cooperate with the bolt that needs dismounting and it is disassembled, and sleeve assembly 11 can positive and negatively rotate under the drive of quill 8, realizes the purpose of assembling-disassembling bolt.
Operation principle: during work; Explosive motor 3 is through diesel oil or gasoline self power generation and outputting power; Its output shaft is through clutch 6 rear drive duplex pumps 4; Duplex pump 4 converts machine power the pressure of fluid to and exports to hydraulic pressure cooling system 51, and fluid is inputed to solenoid directional control valve 52 after the cooling cooling again in hydraulic pressure cooling system 51, and solenoid directional control valve 52 is transformed into the flow direction of fluid vertical direction and inputs to hydraulic motor 53; Hydraulic motor 53 converts the pressure of fluid 9 rotations of into two idle wheels of machine power rear drive again, and two idle wheels 9 rotate through the quill 8 of corresponding sleeve shaft gear 10 drive both sides respectively again; Because sleeve assembly 11 is to be threaded on the quill 8, therefore when quill 8 rotations, produce relative motion between 11 meetings of sleeve assembly and the quill 8, promptly rotate.Through the rotation of sleeve assembly 11, just can realize installation and removal to bolt, specifically select the installation or removal bolt, be to realize by the forward or reverse of control hydraulic motor 43.After the installation or removal of bolt are accomplished, lift the handle of frame, just can make the lifting of sleeve assembly and separate with bolt, just can equipment be moved to next bolt position then and operate.
Operate and observe pressure condition for ease, pressure sensor 12 also is installed on sleeve assembly 11, this pressure sensor 12 is connected with rack-mounted moment of torsion digital display meter 13 through data wire.Through the pressure size cases of moment of torsion digital display meter 13 on can Real Time Observation sleeve assembly 11, and the gear of regulating explosive motor 3 and hydraulic actuating mechanism satisfies the demands power output.
Need to prove; Above embodiment is only in order to explain the utility model technical scheme but not the restriction technologies scheme; Although the applicant specifies the utility model with reference to preferred embodiment, those of ordinary skill in the art should be appreciated that those technical schemes to the utility model make amendment or be equal to replacement; And do not break away from the aim and the scope of present technique scheme, all should be encompassed in the middle of the claim scope of the utility model.
