the inner chamber of the seat 3 of weighing is equipped with foam-rubber cushion 38, U type weighbridge 39 and the layer board 42 that is located between the two, set up foam-rubber cushion 38 in order to avoid balanced seat 2 and the seat 3 of weighing to move down, layer board 42 and the inner wall of balanced seat 2 bump repeatedly, resistance when still can increase layer board 42 to move up simultaneously, give the time that staff control balanced seat 2 and seat 3 of weighing stopped moving down, the lower extreme middle part of layer board 42 is equipped with switching post 41, in order to be convenient for accurate weighing, control mechanism 4 and the grab bucket body 5 of seat 3 below of weighing then can regard as a whole, then measure the weight of rubbish through the weight that subsequently increases, the lower extreme of switching post 41 runs through the diapire of seat 3 of weighing and is equipped with control mechanism 4, the accessible is equipped with grab bucket body 5 at control mechanism 4 installation motor cooperation rope or installation pneumatic cylinder's mode control grab bucket body 5, the grab bucket body 5 that uses here is claw-shaped rubbish grab bucket, its jaw claw, the tip, in order to reduce resistance, conveniently insert the material, improve the excavation power.
From the above, the grab bucket body 5 is moved down by the first wire rope 11, then the grab bucket body 5 is opened and closed again by the control mechanism 4 and its internal components, so as to grab part of the garbage, then the first wire rope 11 is moved up a distance, then the components below the bridge crane 1 are quickly stabilized by the balance seat 2, finally the weight of the grab bucket body 5 after grabbing the garbage is weighed by the U-shaped wagon balance 39, so as to obtain the weight of the garbage.
Specifically, referring to fig. 3, four corners of the upper end of the balancing seat 2 are respectively provided with two connecting plates 20, the two connecting plates 20 positioned on the same side are symmetrical along the diagonal line of the upper end of the balancing seat 2, one ends of the two connecting plates 20 positioned on the same side, which are close to each other, are jointly provided with a rotating rod 201, one end of the rotating rod 201, which is close to the first steel wire rope 11, is provided with a second steel wire rope 12 connected to the lower part of the first steel wire rope 11, four equal-length second steel wire ropes 12 are utilized to balance the four corners of the balancing seat 2, so that the stability of the balancing seat 2 and the components below the balancing seat is accelerated, one end of the second steel wire rope 12, which is close to the water inlet pipe 21, is provided with an elastic telescopic rod 13, and the second steel wire rope 12 can be always in a tense state through the elastic telescopic rod 13, the shaking brought by loosening to tightening of the second steel wire rope 12 is reduced, one side, far away from the rotating rod 201, of the elastic telescopic rod 13 is rotationally connected to the upper end of the balance seat 2, in a working state, the rotating rod 201 is inclined towards the direction close to the water inlet pipe 21 and used for enabling the second steel wire rope 12 to be in a tightening state, in an opening operation of the grab bucket body 5, the rotating rod 201 is inclined towards the direction far away from the water inlet pipe 21 and used for enabling the second steel wire rope 12 to be in a tightening state, and the rotating rod 201 is turned up and down under the action of the elastic telescopic rod 13, so that the second steel wire rope 12 is always in a tightening state, and shaking brought by loosening to tightening of the second steel wire rope 12 is reduced;
therefore, when the grab bucket body 5 is lowered by the first steel wire rope 11, the second steel wire rope 12 is in a stretched state by means of the gravity of the grab bucket body 5, so that an acute angle is formed between the connecting plate 20 and the upper end surface of the balance seat 2, and when the grab bucket body 5 moves to a garbage mountain to carry out grabbing work, the rotating rod 201 can outwards turn under the action of the elastic telescopic rod 13, and the second steel wire rope 12 is outwards pulled, so that the second steel wire rope 12 is continuously in the stretched state, and shaking caused by loosening to stretching when the grab bucket body 5 is extracted again later is reduced.
Further, referring to fig. 3, a water inlet pipe 21 communicating with the inner cavity is provided in the middle of the upper end of the balancing seat 2, water is filled in the balancing seat 2, moving grooves 271 are provided in the middle of the rest inner side walls except the top wall and the bottom wall of the inner cavity of the balancing seat 2, a cross groove is formed by the four moving grooves 271 in cooperation with the inner cavity of the balancing seat 2, moving plates 24 are provided in the four moving grooves 271, sealing gaskets 25 are provided at the ends of the four moving plates 24 close to each other, a first spring 23 is provided between the ends of the four moving plates 24 far away from each other and the inner side walls of the moving grooves 271, so as to facilitate buffering of impact force caused by shaking of water, and reduce shaking amplitude of the balancing seat 2 and the components below the balancing seat 2;
therefore, when the balance seat 2 and the lower components thereof shake, the water source in the balance seat 2 also shakes and flows to one side, then the impact force caused by the water is buffered by compressing the first spring 23, then the water is extruded to the other side by the resilience force of the first spring 23, and the balance seat 2 is given a reverse force, so that the shaking amplitude of the balance seat 2 and the lower components thereof is reduced, and the grab bucket body 5 is quickly stabilized.
Therefore, the specific implementation manner of this embodiment is as follows:
when the grab body 5 is lowered, the second steel wire rope 12 is in a tight state by means of the gravity of the grab body 5, then when the grab body 5 moves to a garbage mountain to carry out grabbing work, the rotating rod 201 is turned outwards under the action of the elastic telescopic rod 13, the second steel wire rope 12 is pulled outwards, so that the second steel wire rope 12 is in the tight state continuously, shaking brought by loosening to tightening when the grab body 5 is extracted again later is reduced, then when the grab body 5 grabs garbage upwards, the balance seat 2 and a component below the balance seat inevitably shake, a water source in the balance seat 2 is caused to shake, one side flows, then the impact force brought by water is buffered by the compression spring 23, then the rebound force of the spring 23 is utilized to enable the moving plate 24 and the sealing gasket 25 to extrude water to the other side, the reverse force is given to the balance seat 2, and the shaking amplitude of the balance seat 2 and the component below the balance seat is reduced, and the grab body 5 is stabilized quickly.
