Description
Technical field
The present invention relates to pipeline construction equipment, and in particular to a kind of ejector sleeve equipment.
Background technique
Pipeline transportation is one of modern three big means of transportation, since its is high-efficient, at low cost, takes up an area less, not vulnerable to environment
The advantages such as influence, in energy supply, petrochemical industry and resident living system using more and more extensive, be the life of modern city
Order line.Horizontal directional drilling technology is that current pipeline both at home and abroad is laid with most commonly used technology, still, is returned in directional drilling crossing
During dragging, the influence of the factors such as specified pulling force that can bear due to the complexity and drilling rod of geology, however it remains many limits
System, heavy caliber, long range, complicated geological river Horizontal directional through-passing in, the problems such as stifled bit freezing, drilling rod are disconnected de- easily occurs.
For the above status, Germany's sea Rake combination micro-tunneling construction proposes direct paving with the characteristics of two technologies of horizontal directional drill
Tube method, direct laying-out tube process are pipe laying methods more advanced at present, are a kind of novel no-dig technique pipeline construction technology, tool
Have that construction area is few, speed is fast, can retract.Prefabricated pipeline can be laid in single continuous pipeline by direct laying-out tube process
With the help of thrust device " ejector sleeve machine ", into ground handling.However, the above ejector sleeve machine using long stroke, high thrust it is hydraulic
Cylinder directly carries out ejector sleeve, and such hydraulic cylinder has biggish manufacture difficulty and a higher manufacturing cost, and ejector sleeve machine equipment compared with
Greatly, the problems such as construction site needed is larger；The holding tube device that the above ejector sleeve machine uses actively clamps for hydraulic radial, needs to be directed to
The setting compression hydraulic cylinder of property, so that equipment cost further increases.
Summary of the invention
In view of this, the present invention provides a kind of double dynamical ejector sleeve machines.
Its technical solution is as follows:
A kind of double dynamical ejector sleeve machine, key are: including two groups of propulsive mechanisms, propulsive mechanism described in two groups is equipped with same
One holding tube seat；
