As shown in fig. 1 to 6, the embodiment of the present invention provides a mechanical lifting counterweight device, which can lift a heavy object to be lifted from a lower position to a higher position, and also can lower the heavy object from the higher position to the lower position; the lifting device is particularly suitable for lifting operation in building construction engineering, and can be applied to operation in other scenes.
Specifically, as shown in fig. 1 to 3, the mechanical lifting counterweight device in this embodiment includes:
the storage container 100, the storage container 100 has a bottom wall 110 and side walls, the side walls are rigid side walls, and the bottom wall 110 has certain elasticity. When a heavy object to be lifted is placed on the bottom wall 110 in the storage container 100, the heavy object placed on the bottom wall 110 is deformed to a small extent by the gravity of the heavy object.
The adjusting assembly comprises an induction plate 200 and a plurality of trigger mechanisms 300, when the storage container 100 is at the lower limit position, the induction plate 200 is located below the storage container 100 and abuts against the bottom wall 110 of the storage container 100, the induction plate 200 can slide along the vertical direction, the trigger mechanisms 300 are triggered when the induction plate 200 slides along the vertical direction, and the sliding distance of the induction plate 200 is positively correlated with the triggering quantity of the trigger mechanisms 300. In other words, the longer the distance that the sensing plate 200 slides, the greater the number of triggering mechanisms 300 that can be triggered; the shorter the distance that the sensor board 200 slides, the smaller the number of trigger mechanisms 300 that can be triggered.
The number of the balance weight blocks 400 is the same as that of the trigger mechanism 300, and the balance weight blocks 400 and the trigger mechanism 300 are in one-to-one correspondence or have a definite correspondence. For example, a single trigger mechanism 300 may control a single weight 400, or a single trigger mechanism 300 may control a plurality of designated weight 400. The top of the mechanical hoisting counterweight device is provided with a steering pulley, a connecting rope 410 is wound on the steering pulley, and two ends of the connecting rope 410 are respectively connected to the counterweight block 400 and the storage container 100. In the present embodiment, in order to balance the weight of the magazine 100 and the related structure thereof, in addition to the clump weight 400 controlled by the trigger mechanism 300, a certain number of foundation weights are provided, and the mass of the foundation weights is substantially equal to the weight of the magazine 100 and the related structure thereof in an unloaded state, that is, the mass of both ends of the connecting rope 410 is substantially equal during unloaded transportation.
The trigger mechanism 300 has corresponding locking state and unlocking state before and after triggering, and when the trigger mechanism 300 is in the locking state, the trigger mechanism 300 limits downward movement of the balancing weight 400; in the unlocked state, the trigger mechanism 300 does not restrict downward movement of the counterweight 400.
In the initial state, the storage container 100 is at the lower limit position, the bottom wall 110 of the storage container 100 is not influenced by the gravity of the heavy object, the sensing plate 200 abuts against the bottom wall 110 of the storage container 100, and the bottom wall 110 is not deformed and does not drive the sensing plate 200 to move. During the jack-up operation, earlier place the area promotion heavy object in storage container 100, storage container 100 diapire 110 takes place deformation under the effect of heavy object gravity, oppresses tablet 200 behind the diapire 110 deformation for tablet 200 slides down, and tablet 200 slides down the back and triggers according to the trigger mechanism 300 of the size drive corresponding quantity of sliding distance. For a triggered trigger mechanism 300, which changes from a locked state to an unlocked state, the counterweight 400 it controls is no longer constrained by the trigger mechanism 300 and can move downward; for the trigger mechanism 300 to be unactuated, it is still in a locked state, which still restricts the downward movement of the weight 400. At this time, since the number of the triggered triggering mechanisms 300 and the weight of the heavy object to be lifted are equal, the mass of the balancing weight 400 capable of moving downward is substantially equal to the weight of the heavy object to be lifted by the belt by reasonably setting the mass of the balancing weight 400. Therefore, in the lifting stage, the driving motor can drive the heavy object to ascend with minimum power; in the idle descent phase, the driving motor drives only the counterweight 400 with the smallest mass to ascend.
For the fixed weight 400, assuming that the lifting height is 10m, the weight 400 has a mass of 1000kg, and the weight to be lifted is 500kg, in a complete lifting process, the total work of the driving motor is as follows: lift phase 10m (1000kg-500kg) 10N/kg + no-load-down phase 10m 1000kg 10N/kg 150 KJ.
For the device in the present application, assuming that the lifting height is 10m and the weight to be lifted is 500kg, the total work of the driving motor in one complete lifting process is: lift phase 10m (500kg-500kg) 10N/kg + no-load-down phase 10m 500kg 10N/kg-50 KJ.
Obviously, the mechanical hoisting counterweight device in the application can reduce energy loss in the lifting operation.
In short, through setting up balancing weight 400 and trigger mechanism 300, can make the total mass of balancing weight 400 roughly the same with the quality of treating promoting the heavy object, reduce the energy loss in the middle of promoting the operation from this, practiced thrift the energy, improved lifting efficiency.
It should be noted that, for the mechanical lifting counterweight device in the embodiment of the present invention, since the adjusting mechanism and the counterweight 400 are still located below the storage container 100 when the storage container 100 is at the lower limit position, that is, the counterweight 400 is located at the lowest position of the entire device, since the counterweight 400 needs to continuously descend when the storage container 100 ascends, the counterweight 400 needs to have a sufficient descending space. Based on the above, the mechanical lifting counterweight device in the embodiment of the invention is particularly suitable for lifting operation of the middle layer in building construction, large-batch heavy objects are moved to the middle layer through a tower crane or other large-scale lifting equipment, and then small-batch heavy objects are dispersedly lifted to other layers through the device; alternatively, a sufficient shaft for the counterweight 400 to descend is reserved in advance below the installation base of the mechanical hoisting counterweight device.
Further, as shown in fig. 2 and 5, the sensing plate 200 can also deflect around its center on the basis that the sensing plate 200 can slide up and down. For the outer periphery of the induction plate 200, its movement in the vertical direction can be decomposed into: firstly, the whole induction plate 200 slides up and down; second, the rotation of the sensing plate 200 around its center of gravity causes the outer periphery of the sensing plate 200 to move up and down relative to the center of gravity. For example, if the left half side of the sensing plate 200 moves downward relative to the center of the sensing plate 200, the moving distance of the left half side of the sensing plate 200 is the distance of the entire sensing plate 200 moving downward plus the distance of the left half side of the sensing plate 200 deflecting downward relative to the center of the sensing plate 200; and the distance that the right half of sensing plate 200 moves downward is the distance that sensing plate 200 moves downward as a whole minus the distance that the right half of sensing plate 200 deflects upward with respect to the center of sensing plate 200.
Obviously, compared to the sensing plate 200 that cannot deflect, the distance that the left half of the sensing plate 200 moves downward is significantly increased, and the distance that the right half of the sensing plate 200 moves downward is significantly decreased, so that the left half with the sensing plate 200 descending more distance can trigger a larger number of triggering mechanisms 300, and the right half with the sensing plate 200 descending less distance can trigger a smaller number of triggering mechanisms 300.
When the distribution of the amount of heavy material placed in the magazine 100 is not uniform, the attitude of the entire magazine 100 during the ascent may be deflected. By arranging the sensing plate 200 to be rotatable, the number of the triggering mechanisms 300 that can be triggered on the side with a large mass distribution is larger, the number of the clump weights 400 that can be lifted on the side is also larger, and the number of the triggering mechanisms 300 that can be triggered on the side with a small mass distribution is smaller, the number of the clump weights 400 that can be lifted on the side is also smaller, so that the defects of the magazine 100 caused by self-deflection can be reduced/eliminated.
In order to realize the deflection of the sensing plate 200, a mounting column is provided on the mounting base, and the top end of the mounting column is movably connected with the sensing plate 200, and the movable connection may be a spherical hinge in the illustration or other connection modes as long as the sensing plate 200 can deflect relative to the center thereof.
In one embodiment, as shown in fig. 3 and 4, the trigger mechanism 300 includes a trigger plate 310, a plurality of trigger slots 312 are disposed on the trigger plate 310, and a trigger block 320 is slidably disposed in the trigger slots 312; when the locking state is reached, the trigger block 320 protrudes out of the trigger slot 312 and stops the counterweight 400; in the unlocked state, the trigger block 320 is retracted into the trigger slot 312. The trigger mechanism 300 comprises a threaded shaft 330, a transmission gear 332 and a transmission rack 334, the induction plate 200 slides along the vertical direction to drive the threaded shaft 330 to synchronously slide, the gear is in threaded connection with the threaded shaft 330, and the transmission gear 332 is meshed with the transmission rack 334; when the transmission rack 334 moves, the trigger block 320 is driven to move.
Specifically, as shown in the figure, the triggering plate 310 in this embodiment is a circular ring-shaped plate body, and the number of the triggering grooves 312 is plural, and the grooves are uniformly distributed around the rotation center of the triggering plate 310. The trigger block 320 is disposed in the partial trigger slot 312, and the trigger slot 312 in which the trigger block 320 is not disposed and the trigger slot 312 in which the trigger block 320 is not disposed are staggered. In the initial state, the threaded shaft 330 is at the upper limit position, the upper end of the threaded shaft 330 abuts against the lower end surface of the sensing plate 200, and the transmission rack 334 is located at the triggering slot 312 where the triggering block 320 is not located. The induction plate 200 descends to push the threaded shaft 330 and enable the threaded shaft 330 to descend, the threaded shaft 330 descends to drive the transmission gear 332 to rotate, the transmission gear 332 rotates to drive the transmission rack 334 to rotate around the gravity center of the trigger disc 310 and move to the trigger groove 312 provided with the trigger block 320 from the trigger groove 312 not provided with the trigger block 320, and in the moving process, the transmission rack 334 pushes the trigger block 320 and enables the trigger block 320 to move from the locking position to the unlocking position.
In the process, the descending distance of the sensing plate 200 is in positive correlation with the weight of the heavy object to be lifted, the descending distance of the threaded shaft 330 is the same as the descending distance of the sensing plate 200, the number of rotation turns of the transmission gear 332 is in positive correlation with the descending distance of the threaded shaft 330, the moving distance of the transmission rack 334 is in positive correlation with the number of rotation turns of the transmission gear 332, the triggering number of the triggering mechanisms 300 is in positive correlation with the moving distance of the transmission rack 334, and the number of the counter weights 400 participating in the lifting operation is the same as the triggering number of the triggering mechanisms 300. That is, the number of the balancing weights 400 participating in the lifting operation is positively correlated to the weight of the weight to be lifted.
It is understood that in the present embodiment, the trigger plate 310 is a circular ring-shaped plate body, and accordingly, the sensing plate 200, the storage container 100, and the like are all in a shape of a circle, a cylinder, and the like. Of course, the trigger tray 310 may be a rectangular tray body, and the sensor board 200, the storage container 100, and the like are rectangular correspondingly.
In one embodiment, a first pushing inclined surface 321 is arranged on the upper surface of the trigger block 320, and when the transmission rack 334 moves, the transmission rack pushes the first pushing inclined surface 321 and drives the trigger block 320 to move to the unlocking position; a second pushing inclined plane 322 is disposed on a side of the trigger block 320 opposite to the trigger plate 310, and the counterweight 400 can push the second pushing inclined plane 322 when moving from bottom to top, so that the trigger block 320 moves from the locking position to the unlocking position. A first spring is arranged between the trigger block 320 and the trigger plate 310, which spring always causes the trigger block 320 to move or has a tendency to move towards the locking position.
In the lifting and ascending process, the transmission rack 334 moves to push the first pushing inclined surface 321, so that the trigger block 320 moves from the locking position to the unlocking position, at this time, the storage container 100 ascends, and the counterweight block 400 descends. When the storage container 100 is lifted, the sensing plate 200 is reset upwards, the transmission rack 334 is reset, and the trigger block 320 is returned to the locking position from the unlocking position under the action of the first elastic element. In the idle-load descending process, the counterweight block 400 ascends, and when the counterweight block ascends to be in contact with the trigger block 320, the second pushing inclined plane 322 is pushed, so that the trigger block 320 moves from the locking position to the unlocking position, and after the counterweight block 400 continuously ascends to the position above the trigger block 320 and is separated from the contact with the trigger block 320, the trigger block 320 returns to the locking position from the unlocking position under the action of the first elastic member. In short, the trigger block 320 does not limit the lifting of the counterweight 400 by providing the second pushing slope 322 and the first elastic member.
In one embodiment, for the induction plate 200 capable of moving up and down and rotating around its center, one end of the threaded shaft 330 near the induction plate 200 abuts against the lower end face of the induction plate 200, and a second elastic member is further disposed between the threaded shaft 330 and the mounting base, wherein the elastic force of the second elastic member always enables one end of the threaded shaft 330 to abut against the lower end face of the induction plate 200.
Alternatively, as shown in fig. 3 and 4, the trigger mechanism 300 includes a longitudinal connecting rod and a transverse connecting rod, both of which are telescopic structures. The longitudinal connecting rod can slide in the horizontal direction, one end of the longitudinal connecting rod is movably connected to the bottom of the induction plate 200, one end of the transverse connecting rod is connected to the longitudinal connecting rod, and the other end of the transverse connecting rod is fixedly connected to the threaded shaft 330. When the sensing plate 200 is deflected, the movement of the connection of the longitudinal connecting rod and the sensing plate 200 is not only in the up-and-down direction but also in the horizontal direction. The sliding of the connection in the up-down direction is transmitted to the threaded shaft 330 through the longitudinal and transverse links, and the sliding of the connection in the horizontal direction is converted into the sliding of the longitudinal links in the horizontal direction and the telescoping of the transverse links without affecting the threaded shaft 330.
In one embodiment, a closed housing 120 is further included, and the magazine 100 is located within the closed housing 120, thereby protecting the safety of the lifting operation.
In one embodiment, as shown in FIG. 6, a connecting string 410 is connected to the weight 400, the connecting string 410 is connected to the storage container 100 through a take-up reel 420, and a coil spring is disposed in the take-up reel 420. For the balancing weight 400 not participating in the operation, the connecting rope 410 connected with the balancing weight is gradually loosened in the ascending process of the storage container 100, and the loosened connecting rope 410 is wound up by the winding wheel 420, so that the phenomenon that the operation is influenced because the connecting rope 410 is too disordered after being loosened is avoided. For the counterweight 400 participating in lifting, the connecting rope 410 connected with the counterweight is always in a tight state, and the force of the coil spring in the winding wheel 420 is far less than the force for promoting the connecting rope 410 to keep the tight state, so that the winding wheel 420 does not wind, and only serves as a connecting piece between the connecting rope 410 and the storage container 100.
In one embodiment, the mass of the counterweight 400 is adjustable, thereby enabling adjustment of the lifting range and adjustment accuracy of the mechanical lifting counterweight device.
In the above embodiment, in order to allow the sensing plate 200 to recover the initial position after being detached from the magazine 100, a third elastic member is provided between the sensing plate 200 and the mounting base, and the third elastic member always causes or has a tendency to move the sensing plate 200 upward.
In the above embodiments, the first elastic member, the second elastic member and the third elastic member may be springs, or may be other structures having elasticity or capable of achieving elastic return, such as elastic bars, damping hydraulic cylinders, and the like.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent should be subject to the appended claims.
