Description
Technical field
The present invention relates to a kind of weight equipment transhipment field, more particularly to a kind of single pile movement system.
Background technology
The manufacture and installation of the single pile segmentation in wind-powered electricity generation manufacturing industry, usually, single pile has all been fabricated inside factory building
Into, but the seldom crane with such large-tonnage in factory building, therefore, realize that the transhipment of single pile is cumbersome in tradition.
In outfield is transported, many large-scale equipments are generally sling part using crane, and one is added on part
A little such as bolt, fulcrums of jack are positioned, when crane slings part, it is easy to because outside strong wind or rope
Unbalance stress cause, rolling for lifting part easily causes collision, or even hurts ground handling operator, and work
After the completion of, also these additional frocks are cut away, brush paint is polished flat and mends, waste time and energy, it is difficult after workpiece positioning
Its position is adjusted.
The utility model of Patent No. 200820010354.4 mentions a kind of three-dimensional positioning vehicle, including pedestal and is connected on pedestal
Roller, be provided with pedestal on lowering or hoisting gear, lowering or hoisting gear and be supported by workbench.Proposed in the patent on a kind of solution
The scheme of problem is stated, traditional crane is replaced using three-dimensional positioning vehicle, replaced with certain risk in the way of ground is transported
Low latitude transhipment, but transhipment when, each dolly is individually controlled, and without fixation track, the tune of the dolly of diverse location
Examination is pretty troublesome, it is necessary to be debugged one by one；And the crooked of carriage walking route is easily caused in operation process, part is small
The overload of car, damages dolly.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of realizes many single pile movement systems of dolly co-operation.
In order to solve the above technical problems, the technical scheme is that：A kind of single pile movement system, its innovative point is：
The walking track walked including some transport carriages set along placed longitudinally single pile lower section and for transport carriage, the transhipment
For rack-and-pinion coordinates between dolly and walking track；
The transport carriage includes main frame and the hydraulic system and control system that are built in main frame；
The walking track is made up of the splicing of some track elements.
Further, the track element includes the base plate and the tooth plate installed in base plate both sides of level laying, the tooth
Plate is vertically-mounted along transport carriage direction of advance both sides, and its flank of tooth is upward.
Further, the main frame is a hollow housing, and its bottom surface is provided with the wheel group with walking rail contact, at it
The two sides of direction of advance are symmetrically installed with the gear coordinated with walking track.
Further, the hydraulic system is successively including pumping source fuel tank, hydraulic pump and the jacking oil circuit being arranged in parallel and drive
Dynamic oil circuit；The jacking oil circuit drives some jacking cylinders being built in main frame, the jacking cylinder to install straight up,
Main frame upper surface is stretched out in its piston rod upper surface, and is moved under hydraulic oil driving；The driving oil circuit drives and is built in master
Hydraulic motor in framework, the hydraulic motor is connected with the gear on main frame, and each gear mesh answers a hydraulic motor.
Further, the control system includes a remote control unit and some is built in inside single transport carriage
Controller, car interior is carried out data transmission using CAN technology.
Further, the jacking oil circuit includes reversing slide valve and some jacking cylinders being arranged in series on the oil circuit,
Also there is a hydraulic lock at described each jacking cylinder position；The driving oil circuit includes reversing slide valve and some is connected on the oil
Hydraulic motor on road.
Further, the base plate upper surface position nearer apart from its front end offers a transverse concave groove A, the base plate
Upper surface end is consequently formed a projection A, and the base plate upper surface position nearer apart from its rear end is corresponding with projection A with one
Transverse concave groove B, similarly, the end of the base plate lower surface forms a raised B corresponding with groove A, and each section of track element is first successively
Tail is connected, composition walking track.
Further, there is a pressure sensor at the jacking cylinder, there is one and pressure sensing on dolly side
The pressure display screen of the connected real-time display pressure value of device.
The advantage of the invention is that：
（1）Because single pile is more huge cylinder, transported using some transport carriages, overcome lifting transhipment and easily shake
The drawbacks of rolling, low latitude operation have potential safety hazard, inefficiency；Single pile for uniformly grow straight shape, each dolly load and other
Operating mode is basically identical, and the dolly on same single pile is jointly controlled using control system, it is ensured that each dolly operating mode is identical, it is to avoid single
Individual dolly load is excessive and damages；Using so that dolly advances in strict accordance with path planned in advance for walking track, prevents
The generation of deviation phenomenon, the walking manner coordinated using rack-and-pinion, dolly is big with the contact area of track, between tooth and tooth
Cooperation will not skid.
（2）Main frame both sides have gear, and the tooth bar with track element both sides coordinates；Main frame bottom has wheel group, with
The contacts baseplate of track element coordinates, and the cooperation of rack-and-pinion provides the power that dolly advances, and wheel group is engaged with base plate,
Reduce the frictional force of walking, carry most of load, while prevent dolly from derailing toppling.
（3）Single car interior realizes jacking cylinder work, drives dolly to advance by a set of hydraulic system；Jacking oil circuit
With driving oil circuit to be arranged in parallel, can individually control, the equipment in each oil circuit realizes jacking cylinder by the way of series connection
The synchronous driving of synchronization of jacking up and gear, it is ensured that uniform jacking and at the uniform velocity advance.
（4）Car interior is carried out data transmission using CAN technology, it is to avoid interference between wire harness and wire harness, section
About the inner space of dolly, is easy to the installation of hydraulic system；Each dolly can be controlled individually, it is also possible to realize wireless connection,
It is easy to, when carrying with root single pile, coordinate between each dolly.
（5）The fit system for being connected by groove and projection between track element, simple structure, installation easy to disassemble.
（6）The setting of pressure sensor and its display device so that the lift-up pressure of jacking cylinder is very clear, helps existing
Staff check jacking cylinder whether overload operation, dangerous situation is found in time.
