Description
Technical field
This utility model relates to the rail jack of high-speed railway construction, uses more particularly, it relates to a kind of
Floating structure bears the hydraulic tool for taking up tracks of unbalance loading.
Background technology
Rail jack, applies to carry out, during trackage is laid and safeguarded, the special tool keeped in repair that raises track
Tool, it is adaptable to the track of rail, track lifting of turnout junction operation, manually plunger displacement pump drives piston to rise,
Drive track lifting lever, make operation take turns fast servo in the track lifting of the track lifting lever front end of rail foot, reach
To track lifting operation purpose.Rail jack mainly has hydraulic tool for taking up tracks and tooth bar rail jack, and hydraulic tool for taking up tracks leads to
Often having underframe, track lifting actuator and hydraulic control device, both are connected with each other and each undertake corresponding
Function.
The complete machine of hydraulic tool for taking up tracks of the prior art mainly by hydraulic system (include hand piston pump,
Hydraulic cylinder and hydraulic circuit) and the part composition such as track lifting parts (such as raise track hook), pass through hands
The hands operation hydraulic system of admiring of dynamic plunger displacement pump drives piston in hydraulic cylinder to rise, thus drives track lifting hook
The rail position that jacking is suitable, reaches the purpose of track lifting operation, and the pressure-relief valve in hydraulic tool for taking up tracks is permissible
After operation completes, hydraulic system is carried out release.
As it is shown in figure 1, be that CN1114395 Chinese invention patent discloses a kind of cunning at Authorization Notice No.
Posture hydraulic tool for taking up tracks, for provide a kind of simple, compact, volume is little, good from heavy and light, serviceability
Rail jack, propose the present invention, it is by working cylinder, fuel tank, plunger displacement pump, oil circuit, control valve and cunning
Posture actuator forms, and slide frame type actuator is made up of chassis and track lifting hook, and chassis is provided with band
