Embodiment
In brief description of the drawings label 1 be rail, 2 be drift, 3 be shift fork, 4 be hold tightly oil cylinder, 5 be hold tightly seat, 6 be pushing tow oil
Cylinder, 7 be mobile platform, 8 be hydraulic control system.
Pushing tow mobile device is held tightly to the utility model automatic hydraulic with reference to the accompanying drawings and detailed description to make into one
Walk explanation：
Embodiment one：In the present embodiment, as Figure 1-3, a kind of automatic hydraulic holds pushing tow mobile device, including rail tightly
1st, hold-fast body, pipe bending cylinder 6 and mobile platform 7, front end and the mobile platform 7 of the pipe bending cylinder 6 are hinged, pipe bending cylinder 6
Rear end be hinged with hold-fast body, the hold-fast body include hold tightly seat 5, drift 2, shift fork 3 and hold tightly oil cylinder 4, it is described hold tightly
Seat 5 is stuck on rail 1, and the drift 2 is plugged in the R-joining for holding seat 5 and the side of rail 1 tightly, and the middle part of the shift fork 3 is hinged
Hold the rear portion of seat 5 tightly, the front portion of the holding oil cylinder 4 is hinged on the front portion for holding seat 5 tightly, hold rear portion and the shift fork 3 of oil cylinder 4 tightly
In upper articulation, the connecting hole of the lower removable insertion drift 2 of the shift fork 3.
The front and rear of the lower end of the shift fork 3 is set to circular arc.
The mobile platform 7 includes the platform for placing weight, and the mesa base is slided equipped with wheel or on rail
Sliding block.
With the Surface Machining toothing of rail contact aside on the drift 2.
The pipe bending cylinder 6 and holding oil cylinder 4 are all connected with hydraulic control system, and the hydraulic control system includes hydraulic oil
The oil inlet of pump, safety valve, reversal valve and two petroleum pipelines, pipe bending cylinder 6 and holding oil cylinder 4 one end is connected in parallel one of them
The oil inlet of petroleum pipeline, pipe bending cylinder 6 and the holding other end of oil cylinder 4 is connected in parallel on another petroleum pipeline, two pipeline roads
Reversal valve is set, and the oil circuit for controlling two petroleum pipelines by reversal valve commutates, and the piston cross-section for holding oil cylinder 4 tightly is less than pipe bending cylinder
6 piston cross-section.
The utility model automatic hydraulic holds pushing tow mobile device tightly in use, mobile workpiece will be needed to be placed on mobile platform
On 7, by the way that hydraulic control system 8 is to pipe bending cylinder 6 and holds the fuel feeding of oil cylinder 4 tightly, the piston rod for holding oil cylinder 4 tightly stretches out pushing tow first
Shift fork 3 stirs drift 2, drift is inserted the side of rail 1 and holds the gap between seat 5 tightly, so that holding seat 5 tightly passes through drift
2 are clamped rail 1, make the strong point of pipe bending cylinder 6, can pushing tow movement when the piston rod elongation of pipe bending cylinder 6
Platform 7 is moved on rail 1, and when pipe bending cylinder 6 reaches range, hydraulic control system 8 controls pushing tow by reversal valve
Oil cylinder 6 and hold tightly oil cylinder 4 start reverse fuel feeding and oil return, now hold tightly oil cylinder 4 drift 2 is stirred by shift fork 3, make drift 2 with
Seat 5 is held tightly to separate, meanwhile, when pipe bending cylinder 6 receives cylinder, now mobile platform 7 because of pressure-bearing weight transfixion, you can light band
Dynamic hold-fast body is moved forward, and is received after cylinder terminates and is repeated aforesaid operations, and making mobile platform 7, discontinuous is moved forward, each
Secondary displacement is the stroke of pipe bending cylinder 6.
The clamping force of hold-fast body is to follow the size of the jacking force of pipe bending cylinder 6 and change, and its force analysis figure is shown in figure
4, drift 2 the respectively thrust F of shift fork 3, holds the pressure P of the seat 5 and active force N of rail 1 tightly altogether by three active forces, its
Middle N can be analyzed to the bigger explanations of normal pressure N1 and frictional force f1, f1 and hold tighter, f1 size and selection that seat blocks with rail 1 tightly
Material, drift angle, surface roughness and pressure P etc. are relevant, therefore are increasing friction force f1, drift surface and rail contact surface
Toothing is processed, pressure P is relevant with the thrust of pipe bending cylinder 6, and thrust is bigger, and P values are bigger, and f1 follows increase, so jacking force
More clamping force follows increase, it is ensured that skidding is occurred without during pushing tow.
The utility model preferred embodiment is described in detail above in conjunction with accompanying drawing, but the utility model
It is not limited to described embodiment.To those skilled in the art, principle of the present utility model and essence are not being departed from
A variety of changes, modification, replacement and deformation are carried out in the case of god to this embodiment and still falls within protection model of the present utility model
In enclosing.
