The invention relates to a free combined-type multi-lifting-point crane carriage which is characterized by comprising a plurality of lifting units and a driving device, wherein every two adjacent lifting units are connected with each other by a detachable connecting component; each detachable connecting component comprises a connecting beam and a connecting frame component; each connecting frame component comprises a mounting plate; two connecting frame plates arranged in parallel are arranged on each mounting plate; a connecting beam mounting groove is formed between the two connecting frame plates on each mounting plate; each connecting beam is arranged in the corresponding connecting beam mounting groove; a pin shaft passes through the part between each connecting beam and the corresponding connecting frame plate; the outer side of each connecting frame plate is provided with a fixed shaft plate by a connecting bolt component; each pin shaft is provided with a fixed shaft groove in the position corresponding to that of each fixed shaft plate. After the technical scheme is adopted, the defects of an existing crane carriage with an integral structure are fundamentally solved, and the free combined-type multi-lifting point crane carriage is relatively simple in structure; the production demand can be met by the common processing equipment; the free combined-type multi-lifting point crane carriage is relatively convenient to install and use; furthermore, the free combined-type multi-lifting point crane carriage is high in universality and convenient to maintain and replace, and the maintenance cost is lowered.
Description
Technical field
The invention belongs to hoisting crane manufacturing technology field, particularly relate to a kind of structural shape for many suspension centres crane carriage.
Background technology
At present, crane carriage is generally integral structure, and a plurality of fixed point lifting mechanisms are installed on crane carriage, to the crane carriage of a plurality of lifting mechanisms is installed, has many limitation:
1, aspect difficulty of processing, the trolley frame Product Precision of whole processing is relatively high, but higher to the requirement of equipment, equipment investment is large.
2,, aspect integral frame, crane carriage can not be disassembled, oad more greatly, thereby it is high to cause traffic cost to hand over;
3, aspect Installation and Debugging, integrally-built wherein dolly integral body is heavier, and volume is larger, in installation, debugging, relatively wastes time and energy.
4, aspect dolly safeguards, more difficult, and maintenance cost is higher, for example when breaking down, part need to carry out field-strip to whole dolly, extend maintenance cycle, in addition, do not there is convertibility, even if can change certain lifting mechanism on dolly, when actual job, be also more difficult.
Summary of the invention
The present invention provides a kind of many suspension centres of free modular crane carriage for solving the technical matters existing in known technology; The present invention has fundamentally solved many defects that existing integrally-built crane carriage exists, and it is structurally simpler, is installing and is using convenient; And commonality is high, convenient maintenance and replacement, the maintenance cost that reduced.
The technical scheme that the present invention takes for the technical matters existing in solution known technology is:
A kind of many suspension centres of free modular crane carriage, it is characterized in that: described crane carriage mainly comprises several liftings unit and actuating device, between adjacent lifting unit, by detachable coupling assembling, connect, each lifting unit comprises two end carriages that be arranged in parallel, installation car wheels on two end carriages; Between two above-mentioned end carriages, girder is installed, on described girder, lifting mechanism is installed; Described detachable coupling assembling comprises tie-beam, link span assembly, wherein said link span part assembly comprises adapter plate, adapter plate be provided with the connection frame plate be arrangeding in parallel, between two connection frame plates, formed tie-beam mounting groove, described tie-beam is placed on tie-beam mounting groove, described tie-beam is coated with bearing pin with being connected between frame plate, and the outside of described connection frame plate is provided with dead axle plate by tie bolt assembly, and corresponding dead axle Board position bearing pin is provided with dead axle groove.
The present invention can also adopt following technical measures:
Between described connection frame plate and tie-beam, be provided with adjusting pad.
On described actuating device, be shaped with the interface general with each wheel group.
Advantage and good effect that the present invention has are: because the present invention is by technique scheme, adopt multi-point combination mode, fundamentally solved many defects that existing integrally-built crane carriage exists, it is structurally simpler; In processing, be more prone to, adopt common process equipment just can meet Production requirement; Installing and using convenient; And commonality is high, convenient maintenance and replacement, one of them unit do not affect other unit normal operation after damaging, thereby have reduced maintenance cost.
