Detailed description of the invention
Technical scheme of the present invention is further illustrated below in conjunction with drawings and Examples.
Seeing figures.1.and.2, shore container crane orderly closedown position is carried out the transformation of crossbeam lengthening, is main purpose of the present invention, and after also not repelling bridge crane displacement, identical transformation is done in other positions simultaneously.
The crucial end being crossbeam 5 of transformation of the present invention, namely head blocks the transport of the reach of part 1, the lengthening section 3 of crossbeam, and lengthening section 3 and head block the docking of truncation surface of part 1, crossbeam 5.
The transportation resources of all material, the reach that head blocks part 1 is key of the present invention, therefore needs home-built equipment frock to be realized.The present invention exactly can under bridge crane need displacement situation, and just need not can realize the transformation that crossbeam lengthens by the main equipment as crane barge, be that the duration is shorter comparatively speaking, the professional technique that expense is lower.
The present invention needs homemade equipment to comprise transport trolley 4 and slippage crane 2.Transport trolley 4 in order to material and frock are transported to crossbeam head, and is used for site operation as workplatform.Slippage crane 2 is front moving devices that crossbeam head blocks part 1.
With reference to Fig. 3 and Fig. 4, slippage crane 2 has two covers, and be arranged on the crossbeam 5 of hoisting crane, both sides are each a set of, and often cover comprises outrigger 21, oil cylinder 22, hand cart 23, chain block 24, shackle 25, channel-section steel 26.
Outrigger 21 is arranged at the top of crossbeam 5 abreast, and its end stretches out the end of crossbeam 5.Preferably, the distance that the end of outrigger 21 stretches out crossbeam 5 is more than or equal to the length of crossbeam lengthening section 3.Arrange channel-section steel 26 in the middle of two outriggers 21, channel-section steel 26 is vertical with outrigger 21.
Oil cylinder 22 is arranged at the initiating terminal of outrigger 21, and can stretch along the length direction of outrigger 21, promotes or pulls head to block the motion of part 1 on outrigger 5.
Lay track inside crossbeam 5, hand cart 23 is arranged on track, and direction along ng a path moves back and forth.Netted reinforcement grid are also set between crossbeam 5 and outrigger 21, are used for strengthening outrigger 21 fixing on crossbeam 5.
Shackle fixed mount is slidably disposed in the end of outrigger, arranges shackle 25 in the clasp of shackle fixed mount, and chain block 24 hangs in shackle 25, namely hangs on below shackle fixed mount.Head blocks part 1 and is hung by hanger, and hanger is arranged on chain block 24.
Transport trolley 4 is arranged on the track inside crossbeam 5, rail same with hand cart 23, is the load transfer device of lengthening section 3, can ensure lengthening section 3 transport and last on move on to and lengthen position.Transport trolley 4 comprises the delivery platform for carrying crossbeam lengthening section 3, and delivery platform is high-temperature operation platform, and for welding job, delivery platform can vertical lift.
Enter shown in Fig. 5, except above-mentioned specialized equipment, the present invention also discloses a kind of Crane Beam lengthening method utilizing the said equipment to carry out, and comprises the following steps:
S1: before construction, needs the parts of interfering with engineering or structure to disassemble, and as dolly, hoist rope and associated components, all needs to depart from the connection blocking part with head.
Auxiliary material and work are placed on hoisting crane main carriage, are placed on transport trolley 4 by lengthening section 3 by S2: provide driving for oneself with hoisting crane, and with traveling crane on trolley track, promote transport trolley 4, all material and frock are transported to crossbeam head with main carriage.Crossbeam head is the preferred location that crossbeam blocks lengthening.
S3: mounting slip crane 2.Slippage crane 2 is a set of on one side, and be made up of outrigger 21, oil cylinder 22, hand cart 23, chain block 24, shackle fixed mount, these assemblies are splits, is easy to install location, does not need special equipment to complete.There is introduction above the concrete structure of slippage crane 2, repeat no more here.
S4: head is blocked part 1 and disconnect with the back segment of crossbeam 5, be connected by hanger, chain block 24 and hand cart 23 with slippage crane 2, specifically, driven by oil cylinder 22, promote hand cart 23 and move forward, head is blocked part 1 and transfer forward, until reach desired location, transfer distance is relevant with concrete extension length, for lengthening section 3 be two or more case distance of positions from, can segmentation complete.
S5: lengthening section 3 is parts that crossbeam lengthens, length 2.5 meters (lengthening according to a case position).Lengthening section 3 is on transport trolley 4, and be positioned at below crossbeam 5, disconnect the back lower place in cross section, by two chain blocks 24, lengthening section 3 can be promoted to lengthening position, namely with chain block 24 it is directly hung in front crossbeam 5 from transport trolley 4 and head blocks between part 1, then butt welding, blocks part 1 by the back segment of lengthening section 3 and crossbeam 5 and head and docks.
S6: check weldquality, and the follow-up work such as polishing, paint, remove tool part, the connection of recovery steel rope and appurtenances etc.
S7: the functional rehabilitation needed because of transformation or extension recover, main finger is positioned at that deceleration on crossbeam is spacing, spacing displacement of stopping, the lengthening of collision avoidance system, and inside machine room because of lengthen need improve, as in hoist rope (even comprising reel), dolly and holder cable dolly (if any) and control system corresponding program setting.
Those of ordinary skill in the art will be appreciated that, above specification sheets is only one or more embodiments in the numerous embodiment of the present invention, and not uses limitation of the invention.Any equalization for the above embodiment changes, modification and the equivalent technical scheme such as to substitute, as long as spirit according to the invention, all will drop in scope that claims of the present invention protect.
