Description
Technical field
The utility model belongs to weight-lifting equipment technical field, specifically a kind of hoisting crane test mass device.
Background technology
According to relevant specification of country, standard regulation: at the carrying structure of manufacture, transformation and hoisting crane or parts, after repairing, the hoisting crane of place in operation first, should verify the performance of hoisting crane.For general small-sized portal machine, counterweight is not difficult to solve, but to some goliaths, the goliath that particularly remote districts are used, if power station is a large problem with hoisting crane.The appearance of test mass water bag efficiently solves the problems referred to above, in long-term use, finds that existing test mass water bag also exists larger problem, mainly: one, discharge opening is arranged at water bag bottom, for hoisting of water bag, causes adverse effect; Two, water bag is filled with after water, even just produce slight rocking, because weight is larger, also can produce greater impact power to suspender beam.
Existing suspender girder construction is mostly one-piece construction in addition, and weight one end is all at tens tons, and this shifts just to carrying and has brought very large inconvenience.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of hoisting crane test mass device simple in structure, ingenious, rational is provided, and this device has advantages of good, the detachable convenient transportation of balance.
The technical scheme providing according to the utility model: a kind of hoisting crane test mass device, be characterised in that: comprise suspender beam body, described suspender beam body middle part is fixed with intermediate beam, suspender beam body two ends are respectively equipped with lifting beam, on each lifting beam, all hang and be provided with the first water bag, described intermediate beam bottom is provided with bearing block, bearing block two ends are hung respectively and are provided with second water bag, described the first water bag is identical with the second water bag structure, in the middle of suspender beam body, be formed with lug boss, described lug boss is provided with hanger, hoisting wirerope lower end is connected on described hanger, upper end is connected on hoisting crane suspension centre.
As further improvement of the utility model, between described suspender beam body and lifting beam, be bolted connection, load-bearing ear in lifting beam two ends is provided with bearing pin, and the first water bag is hung on described bearing pin by steel rope.
As further improvement of the utility model, on the load-bearing ear of described lifting beam, be equipped with two suspension centres, each suspension centre is equipped with bearing pin.
As further improvement of the utility model, described the first water bag upper face is provided with water inlet, and lower side is laid with some dragging a little, and bag surface is also provided with bag sheath.
Compared with prior art, advantage is the utility model: in the utility model, load-bearing suspender beam is detachable, conveniently moves transhipment, and the intermediate beam simultaneously adding makes integral structure have good balance quality; Meanwhile, the utility model has also carried out particular design to water bag, so that can effectively keep integrally-built stability in water filling operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, comprise suspender beam body 1, intermediate beam 2, hanger 3, hoisting wirerope 4, bearing pin 5, the first water bag 6, lifting beam 7, bearing block 8, the second water bag 9, bag sheath 10, drag a little 11, water inlet 12 etc.
As Fig. 1, shown in Fig. 2, a kind of hoisting crane test mass of the utility model device, comprise suspender beam body 1, described suspender beam body 1 middle part is fixed with intermediate beam 2, suspender beam body 1 two ends are respectively equipped with lifting beam 7, on each lifting beam 7, all hang and be provided with the first water bag 6, described intermediate beam 2 bottoms are provided with bearing block 8, bearing block 8 two ends are hung respectively and are provided with second water bag 9, described the first water bag 6 is identical with the second water bag 9 structures, in the middle of suspender beam body 1, be formed with lug boss, described lug boss is provided with hanger 3, hoisting wirerope 4 lower ends are connected on described hanger 3, upper end is connected on hoisting crane suspension centre.
Between described suspender beam body 1 and lifting beam 7, be bolted connection, lifting beam 7 two ends load-bearing ears are provided with bearing pin 5, the first water bags 6 and are hung on described bearing pin 5 by steel rope.
On the load-bearing ear of described lifting beam 7, be equipped with two suspension centres, each suspension centre is equipped with bearing pin 5.
Described the first water bag 6 upper faces are provided with water inlet 12, and lower side is laid with somely drags a little 11, and bag surface is also provided with bag sheath 10.
The utility model is when work, lifting beam 7 is definitely installed on suspender beam body 1 two ends in position by bolt and fixed angles, on the load-bearing ear at lifting beam 7 two ends, be fixed with for connecting the bearing pin 5 of track cable, the first water bag 6 is hung on lifting beam 7 by track cable, in when work, can only hang in the every one end of lifting beam 7 according to specific needs and establish a water bag and also can hang in every one end and establish two water bags; Intermediate beam 2 is bolted connection equally on suspender beam body 1, intermediate beam 2 is hung oneself and is provided with the second water bag 9, after carrying out above-mentioned dead work, can in each water bag, carry out water filling operation, owing to being difficult to remain that suspender beam body 1 is all the time in state of equilibrium in the injecting process, so be also provided with, for what adjust water bag position, drag a little 11 on water bag, in the injecting process, can drag a little 11 pairs of water bag positions by tractive and adjust, to guarantee that suspender beam body 1 is all the time in state of equilibrium; The water injection rate simultaneously needing due to water bag is larger, generally all tens tons upper and lower, in order to guarantee that the intensity of water bag is also provided with bag sheath 10 on water bag surface especially.
