Abstract
The utility model discloses a straight arm frame assembling and disassembling a gantry crane, which is provided with an amplitude pulley block and is characterized by comprising two I-shaped beams, a plurality of pairs of first strut members and a plurality of second strut members, wherein the two I-shaped beams are parallelly arranged; the plurality of pairs of first strut members and the plurality of second strut members are arranged between the two I-shaped beams; each pair of first strut members are arranged crosswise; and two ends of each first strut member and each second strut member are connected with the webs of the two I-shaped beams. The straight arm frame has simple structure and light self weight, and does not need an additional balance device.
Description
Technical field
The utility model relates to the handling door machine, relates in particular to the straight-arm shelf structure of handling door machine.
Background technology
Present domestic stevedoring door machine all adopts four traditional connecting rod forms, the Four-link door facility have the luffing performance good, can bear bigger advantages such as goods beat, but the boom system of Four-link door machine structurally has following defective: from great, need extra balanced system to come balance jib weight, complex structure, accuracy of manufacture requires high.
Summary of the invention
Technical problem to be solved in the utility model be to provide a kind of simple in structure, from the straight-arm frame of the handling door machine of heavy and light.
The technical scheme that the utility model adopted is: a kind of straight-arm frame of handling door machine, on this straight-arm frame, be provided with the luffing assembly pulley, be characterized in, this straight-arm frame comprises two H-girders, many to first strut member and Duo Gen second strut member, two H-girders be arranged in parallel, many first strut member and Duo Gen second strut member are arranged between these two H-girders, each is arranged in a crossed manner to first strut member, and the two ends of each first strut member and each second strut member are connected with the web of two H-girders respectively.
Above-mentioned straight-arm frame, wherein, the length of this straight-arm frame is L, free-ended at distance straight-arm frame
The place is provided with a crossbeam, and the luffing assembly pulley is arranged on this crossbeam.
Above-mentioned straight-arm frame, wherein, the web inboard of each described H-girder is provided with polylith joint backing plate and many reinforced ribs, and described polylith joint backing plate and described many reinforced ribs are along vertical arrangement of web, and are located on the same line; The two ends of each described first strut member respectively with two H-girders on the joint welding with backing connect.
The utlity model has following advantage:
1. simple in structure.
2. from heavy and light, balanced system that need not be extra.
3. the luffing assembly pulley is arranged in apart from straight-arm frame free end approximately
The position of straight-arm frame length overall utilizes the rear portion deadweight of the dead-weight balanced straight-arm frame of free end of straight-arm frame, reduces the weight stress of straight-arm frame.
4. the straight-arm frame adopts the twin I-beam main structure, the longitudinal rib of the second strut member arrangement utilizing web, and both convenient the manufacturing processed, and improved the anti-fatigue performance of straight-arm shelf structure again.
Description of drawings
Fig. 1 is that master of the present utility model looks scheme drawing.
Fig. 2 is a schematic top plan view of the present utility model.
Fig. 3 is the cross sectional representation of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is made and to be further specified.
As illustrated in fig. 1 and 2, the straight-arm frame of handling door machine of the present utility model comprises two H-girders 1, many to first strut member 2 and Duo Gen second strut member 3.Two H-girders 1 be arranged in parallel, many first strut member 2 and Duo Gen second strut member 3 are arranged between these two H-girders 1, each is arranged in a crossed manner to first strut member 2, and the two ends of each first strut member 2 and each second strut member 3 are welded to connect with the web of two H-girders 1 respectively.Preferably, first strut member 2 and second strut member 3 are pipe fitting.
Also be provided with several crossbeams between these two H-girders 1, wherein crossbeam 41 is arranged on the free-ended end of this straight-arm frame, is provided with compensation pulley group 5 on crossbeam 41.The length of this straight-arm frame is L, and another crossbeam 42 is arranged on apart from straight-arm frame free end
The place is provided with luffing assembly pulley 6 on crossbeam 42.
In conjunction with shown in Figure 3, preferably, the web inboard of each H-girder is provided with polylith joint backing plate 11 and many reinforced rib (not shown)s, this polylith joint backing plate and many reinforced ribs are along vertical arrangement of web, and be located on the same line, the two ends of each first strut member 2 respectively with two H-girders on 11 welderings of joint backing plate connect.Joint backing plate 11 had herein both played the effect that connects first strut member, can play the effect of serving as the web waling again, and joint backing plate and reinforced rib are arranged in sustained height, can guarantee that reinforced rib is in web continuity longitudinally.
