Description
Technical field
The present invention relates to combined plates to lift field, flat more specifically to a kind of ultralong overweight combined plate handling
Balance beam device.
Background technique
Current cabin hatch lid top panel combined plate handling generally hangs wirerope using lifting equipment and passes through matched plate
Card carries out the operation of handling combined plate.As shown in fig. 7, the schematic diagram of existing hoisting structure, the lower part of crane suspension centre (1) is to hang
With wirerope (2), the both ends of wirerope are connected to the first plate suspension centre (3) and the second plate on lifting plate (5) top
On material suspension centre (4).Lifting plate (5) is lifted the both ends of plate (5) by effect of weight during lifting it can be seen from Fig. 7
Often be bent downwardly deformation, plate sling after stay deformation 6, plate sling after arch deformation 7.Due to 400,000 tons of ores in sand form
Shipload cabin hatch board plate is mostly overlength, overweight combination based plate, and the veneer thickness of these combined plates is usually 8-11mm, phase
To relatively thin, as the bending deformation phenomenon generated in Fig. 7 is particularly acute in lifting operation.
Moreover, wirerope allows distracted angle [alpha] to have limitation, usual α in hoisting operation safety operation institute allowed band
≤ 60 ° of angles, thus along lifting plate (5) length direction distribution two groups of boards between spacing i.e. the first plate suspension centre (3) and
Spacing between second plate suspension centre (4) is smaller.Therefore, when lifting plate (5) specification is too long or plate thickness compared with
Bao Shi, since distance is smaller between the first plate suspension centre (3) and the second plate suspension centre (4) of panel length directional spreding,
And the lifting plate (5) for stretching out suspension centre two sides is longer, under the influence of its self weight, lifting plate (5) bending deformation is just further tight
Weight frequently can lead to lifting plate (5) and generate permanent deformation, and since the amount of staying at lifting plate (5) both ends is excessive, often very
Difficulty is sling, or even can lead to occur during handling the danger that plate slides because plate two sides are in outside the effective control range of handling
Danger.

Specific embodiment
As shown in Fig. 1~5, the present invention includes equalizer bar upper beam 8 and the equalizer bar upper beam 8 equalizer bar disposed in parallel
Underbeam 9 is connected with reinforcement structure 10 between the equalizer bar upper beam 8 and the equalizer bar underbeam 9；If the reinforcement structure 10 is
It does slanting steel pipe group is connected with oblique (180 ° of-α) angle transverse direction head and the tail with the oblique angle α each other and is integral.The equalizer bar upper beam 8
It is lightweight square steel tube with the equalizer bar underbeam 9.The 8 top interval of equalizer bar upper beam is set there are two symmetrical first lifting lug
12；Several second lifting lugs 13 are arranged on the equalizer bar underbeam 9,13 lower part of the second lifting lug is connected by two lifting ropes 11
It is connected to board a.
As shown in fig. 6, the board a includes being hinged on the pincers with the caliper 20 for accommodating lifting 5 recess of plate
The top of the nipper 18 of the recess front end of body 20, the nipper 18 is equipped with loser 18a.The nipper 18 by spring 19 with it is described
Caliper 20 connects, and is being kept between the nipper 18 and the lifting plate 5 after lifting as locking state.
Embodiment:
As shown in Figures 1 to 3, a kind of ultralong overweight combined plate handling balances boom device, is made using the square steel tube of light weight
Equalizer bar upper beam 8 and equalizer bar underbeam 9, and use the square steel tube oblique welding equalizer bar upper beam 8 and the equalizer bar underbeam 9
Between reinforcement structure 10 as diamond shape, the reinforcement structure 10 by the connection type between several square steel tubes be Oblique 45 Degree and
Oblique 135 degree laterally join end to end and form a whole, and install two the first lifting lugs 12 in the equalizer bar upper beam 8, and two
First lifting lug 12 is separately mounted at a quarter of the equalizer bar upper beam 8 from left to right and at 3/4ths.Institute
It states equalizer bar underbeam 9 and four the second lifting lugs 13 is installed, four second lifting lugs 13 are separately mounted to the four of 9 lower part of underbeam
Equally divided position, 2 typical lifting ropes 11 of the lower setting of each second lifting lug 13.
As shown in figure 4, the junction structure of the reinforcement structure 10 of diamond shape and the equalizer bar underbeam 9 are as follows: described to add
The left and right ends of strong structure 10 are groove welding position 16, and rear and front end is reinforcement structure surrounding weld seam 17.
When in use, as shown in Figure 1, lifting equipment will be hung using wirerope with the two of the equalizer bar upper beam 8 first
Ear lifting lug 12 connects, and entire ultralong overweight combined plate handling can be balanced boom device and sling, by four the second lifting lugs of underbeam
Lifting rope 11 is installed, connection is horizontal at each lower extreme point of the lifting rope 11 hangs steel plate board a i.e. hoisting tongs at 13.As shown in figure 3, so
Afterwards by it is horizontal hang steel plate and be mounted on need the combined plate corresponding position of handling, balance boom device in ultralong overweight combined plate handling
Under effect, the stress point along panel length direction increases, and four 13 spacing of the second lifting lug are average, each suspension centre mean forced.
Simultaneously as the spacing between two groups of suspension centres increases, the length that plate both ends are stretched out except suspension centre is smaller, is unlikely to generate serious
Stay deformation.
