The driving mechanism comprises a compactor 20 and a force taking frame 30, the compactor 20 is installed on the frame 10, the compactor is provided with a hydraulic system and a power system, the force taking frame 30 is arranged on the lower end face of the compactor 20, the force taking frame 30 is provided with an installation part for fixing a steel wire rope 50, and under the driving action of the hydraulic system, a pressure head of the compactor 20 is pressed down and is contacted with a bearing surface of the force taking frame 30 to drive the steel wire rope 50 fixed on the force taking frame 30 to be pulled down. Wherein, hydraulic system includes hydraulic cylinder.
In the embodiment, the hydraulic cylinder is used as motive power, the pulley assemblies formed by the pulleys 40 and the steel wire rope 50 are used for compactly arranging all functional parts in the frame 10, and the stroke of the hydraulic cylinder is amplified by 4 times through the cooperation of the pulley assemblies and the steel wire rope 50, so that the operation of the tipping bucket 60 has the characteristics of stable hydraulic cylinder, controlled whole process and large stroke of the transmission of the steel wire rope 50.
In this embodiment, the number and positions of the pulleys 40 may be appropriately adjusted according to actual needs, and in this embodiment, the pulley assemblies formed by the pulleys 40 are arranged in two sets, where 7 pulleys 40 are arranged in each set of pulley assemblies.
The guide rails comprise a first guide rail 11 and a second guide rail 12 which are vertically arranged and obliquely arranged, the first guide rail 11 and the second guide rail 12 are connected smoothly, a limit beam is arranged at the top of the second guide rail 12, and the tipping bucket 60 moves vertically upwards along the first guide rail 11 under the driving action of the driving mechanism and overturns at the top of the second guide rail 12.
The main forces during the ascent and descent of the dump body 60 will be analyzed, the main forces including:
self-weight W of tipping bucket 1 Gravity W of garbage 2 The method comprises the steps of carrying out a first treatment on the surface of the The lifting force F of the wire rope 50 on the dump body 60; a restraining force P imparted by the track to the first roller 61 of the dump bucket 60; the frame 10 gives a supporting force S to the second roller 62 of the dump box 60; and friction force f when the upper and second rollers of the skip 60 move on the frame 10 and the rail.
The suspension point position of the dump bucket 60 satisfies the following force balance equation,
F*L＜W*L 1 ，
wherein F is the lifting mechanism when the lifting mechanism lifts the empty bucket 60The required lifting force L is the force arm from the lifting force F to the supporting point of the second roller 62 of the tipping bucket 60, W is the self weight of the tipping bucket 60, L 1 Which is the arm of force from the center of the skip 60 to the point of support of the second roller 62. Only when the conditions are met, the phenomenon that the tipping bucket 60 tips over firstly can not occur when the empty tipping bucket 60 is lifted, and the tipping bucket 60 can not tip over when being lowered and reset.
However, if the L value is too small, the restraining force P, the supporting force S and the friction force f acting on the frame 10 are all greatly increased, the strength of the device is increased, and the mechanism consumes more power to overcome the additional balance force added thereby.
In this embodiment, dumping of the dump box 60 is completed by using a closed structure at the upper end of the track, and when the dump box 60 rises to the height of dumping garbage, the first roller 61 of the dump box 60 abuts against the limit beam of the second guide rail 12, and the first roller 61 cannot continue to move upwards; however, the lifted wire rope 50 continues to lift the dump box 60, and at this time, the dump box 60 can only turn upwards with the first roller 61 as a rotation center until the wire rope 50 is pulled to an upper limit position set by the device, thereby dumping garbage. When the dump body 60 is completely unloaded, the ram of the compactor 20 is retrieved, and the dump body 60 is rotationally reset and lowered along the track to the receiving position of the dump body 60.
The lifting and dumping of the garbage by the dump bucket 60 is performed, and the problem of scattering of the garbage and flying of the light garbage exists, in order to solve the problem, the dump bucket lifting mechanism of the embodiment is further provided with a dump bucket cover 70, two sides of one end face of a dump bucket contact surface 701 of the dump bucket cover 70 are provided with support hinge holes 71, the support hinge holes 71 are hinged at the end part of the second guide rail 12 through hinges, and a third roller 72 is installed at the end of the other end of the dump bucket contact surface 701. The dump housing 70 rotates about the support hinge hole 71 as a rotation center by an external force. The third roller 72 is used in combination with the reset groove 63 provided on the dump box 60 to realize the reset operation of the dump box cover 70.
When the butt joint of the dump housing 70 and the dump 60 is completed, the area of the dump contact surface 701 of the dump housing 70 is equal to or larger than the area of the top surface 601 of the dump 60. That is, the tip contact surface 701 of the tip cover 70 completely covers the top surface 601 of the tip 60, and when the tip 60 dumps the garbage, the tip 60, the tip cover 70 and the inlet of the container are completely connected to form a closed space, and the dumped garbage can only enter the container, and basically no large gap exists to enable the garbage to leak. Furthermore, since the air in the container and the garbage in the dump box 60 are subjected to the position exchange in the closed space, the light garbage is blocked in the closed space, and after the air flows smoothly, the light garbage falls into the container.
The lifting method based on the tipping bucket lifting mechanism comprises the following steps:
step one, the pressure head of the compactor 20 starts to be pressed down under the drive of a hydraulic system;
step two, when the lower end surface of the pressing head of the compactor 20 enters the power take-off frame 30 and contacts the load-carrying surface of the power take-off frame 30, the pressing head and the power take-off frame 30 together drive the steel wire rope 50 fixed on the power take-off frame 30 to pull down;
step three, lifting the tipping bucket 60 along the guide rail on the frame 10 by the power take-off frame 30 through the pulley 40 and the steel wire rope 50;
fourth, when the first roller 61 of the skip 60 is lifted to the top end of the second rail 12, the skip 60 is turned over under the limit action of the limit beam as the wire rope 50 is pulled up.
Wherein, the first roller 61 and the second roller 62 of the tipping bucket 60 move upwards along the first guide rail 11 until the top surface 601 of the tipping bucket 60 contacts with the third roller 72 arranged on the tipping bucket contact surface 701 of the tipping bucket cover 70; the dump cover 70 is driven by the lifting of the dump 60 to rotate and fold with the dump 60, and the position of the third roller 72 gradually moves forward and moves into the reset groove 63 of the dump 60; when the first roller 61 of the skip 60 is raised to the top of the second track, the skip 60 and the skip cover 70 are completely closed together. In this embodiment, the tipping bucket cover 70 and the tipping bucket 60 are abutted by the lifting movement of the tipping bucket 60, and the tipping bucket cover 70 and the tipping bucket 60 are folded into a whole after the butt joint, so that the dumping of the garbage is completed. The specific lifting process is shown in detail in fig. 1, 2, 3 and 4.
As shown in fig. 6, as the wire rope 50 is further pulled up, the dump box 60 and the dump box cover 70 are turned over together, and as the turning angle of the dump box 60 increases, the garbage in the dump box 60 enters the container along the discharge path formed by the dump box 60 and the dump box cover 70. When the dump bucket 60 dumps the garbage, the dump bucket 60, the dump bucket cover 70 and the feeding hole of the container are connected into a closed space, and the dumped garbage can only enter the container, so that basically no larger gap exists to enable the garbage to leak and fall.
After the dump bucket 60 is unloaded, the pressure head is recovered, the dump bucket 60 is rotationally reset and descends to the receiving position of the dump bucket along the track, and the method specifically comprises the following steps:
after the dump bucket 60 is unloaded, the dump bucket 60 starts to turn over and reset under the action of self gravity, at this time, the reset groove 63 of the dump bucket 60 is buckled on the third roller 72 of the dump bucket cover 70, and the dump bucket 60 pulls the dump bucket cover 70 to reset and rotate; the third roller 72 on the tipping bucket cover 70 gradually slides out of the reset groove 63 of the tipping bucket 60 along with the rotation and descending of the tipping bucket 60, and stops rotating under the supporting action of the frame 10, and the tipping bucket cover 70 is reset; the dump box 60 continues to descend with the lowering of the wire rope 50 until the resetting is completed.
The key of whether the skip 60 and the skip cover 70 can be rotated and reset is as follows: the restoring rotational torque provided by the dump body 60 is greater than the restoring torque of the dump body cover 70, i.e. the weight and the center of gravity of the dump body cover 70 must be controlled within a certain range, otherwise the dump body 60 and the dump body cover 70 will stay in this position and cannot be restored.
During the resetting, the rotational centers of the dump bucket and the dump cap 70 are not on the same axis. At the initial stage of resetting, the dump truck drags the dump truck cover 70 to rotate, when the gravity center of the dump truck cover 70 rotates through the rotation axis, the dump truck cover 70 rotates and resets under the action of gravity, at this time, the side upper edge of the dump truck 60 supports the hinge mounted on the support hinge hole 71 of the dump truck cover 70 and controls the overturning speed of the dump truck cover 70. At the same time, the third roller 72 of the skip cover 70 gradually slides out of the reset groove 63 of the skip 60 along with the rotation and the descent of the skip 60, and stops rotating under the support of the frame 10, thereby completing the reset. The dump box 60 continues to descend with the lowering of the wire rope 50 until the resetting is completed. The illustrations of the reset procedure and the lifting procedure are reversed, the reset procedure being seen in turn in fig. 6, 4, 3, 2 and fig. 1 of the initial position.
The resetting of the skip 60 is also accomplished under the force and rail constraints described above. When the wire rope 50 is lowered, the first roller 61 of the skip 60 descends along the second track 12 under the combined action of the gravity center and the lifting point; subsequently, the dump box 60 starts to turn over and reset by the center of gravity with the first roller 61 as a fulcrum. Wherein the inclined arrangement of the second guide rail 61 is the key to enabling the resetting of the skip 60. If the first roller 61 falls onto the first guide rail 11, the skip 60 will go down directly without resetting. It is therefore necessary to ensure that the first roller 61 is turned over on the obliquely arranged second guide rail 12 and after turning over, is smoothly moved along the second guide rail 12 to the vertically arranged first guide rail 11, and gradually completes the reset.
The application effectively utilizes the frame, the compactor and the power take-off frame, adopts the hydraulic oil cylinder as power, and uses the stroke amplification effect of the steel wire rope and the pulley assembly, so that the mechanism has the advantages of stable lifting of the hydraulic oil cylinder and no falling prevention device at the power end, and obtains larger lifting stroke of the lifting mechanism; the application fully utilizes gravity, lifting force, supporting force of the rail and restraining force, and obtains excellent anti-falling effect of the lifting end of the tipping bucket steel wire rope. The parts of the whole mechanism are endowed with multiple functions, so that the structure of the mechanism is greatly simplified, the reliability is greatly improved, and the technical problem of loading garbage into the tipping bucket of a large vertical garbage compression process is effectively solved.
The above embodiments are only for illustrating the technical scheme of the present application, but not for limiting the same, and the present application is described in detail with reference to the preferred embodiments. It will be understood by those skilled in the art that various modifications and equivalent substitutions may be made to the technical solution of the present application without departing from the spirit and scope of the technical solution of the present application, and it is intended to cover the scope of the claims of the present application.
