As shown in fig. 1 to 6, the embodiment of the invention provides a mechanical lifting counterweight device, which can lift a weight to be lifted from a low place to a high place, and can also lower the weight from the high place to the low place; it is particularly suitable for lifting operations in construction works of the building type, but it can of course also be applied to operations therein in other contexts.
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 a side wall, the side wall is a rigid side wall, and the bottom wall 110 has a certain elasticity. When a weight to be lifted is placed on the bottom wall 110 in the storage container 100, the bottom wall 110 is placed with the weight to be deformed by the weight force with a small amplitude.
The adjusting assembly comprises an induction plate 200 and a plurality of triggering mechanisms 300, when the storage container 100 is in a lower limit position, the induction plate 200 is located below the storage container 100 and is abutted to the bottom wall 110 of the storage container 100, the induction plate 200 can slide along the vertical direction, the triggering 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 number of the triggering mechanisms 300. In other words, the longer the distance the sensing plate 200 slides, the greater the number of trigger mechanisms 300 that can be triggered; the shorter the distance the sensing plate 200 slides, the fewer the number of trigger mechanisms 300 that can be triggered.
The balancing weights 400 are the same as the triggering mechanism 300 in number, and the balancing weights 400 and the triggering mechanism 300 are in one-to-one correspondence or have a definite correspondence. For example, a single trigger mechanism 300 may control the state of a single weight 400, or a single trigger mechanism 300 may control the state of a plurality of specified weights 400. The top of the mechanical lifting counterweight device is provided with a diverting pulley, a connecting rope 410 is wound on the diverting pulley, and two ends of the connecting rope 410 are respectively connected with the counterweight 400 and the storage container 100. In this embodiment, in order to balance the weight of the storage container 100 and its related structure, a certain number of basic weights are provided in addition to the weights 400 controlled by the trigger mechanism 300, and the mass of the basic weights is substantially equal to the weight of the storage container 100 and its related structure in the empty state, that is, the mass of both ends of the connecting rope 410 is also substantially equal in the empty transportation.
The triggering mechanism 300 has corresponding locking state and unlocking state before and after triggering, and when the triggering mechanism 300 is in the locking state, the downward movement of the balancing weight 400 is limited; in the unlocked state, trigger mechanism 300 does not limit downward movement of weight 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 acted by the gravity of the heavy object, the sensing plate 200 is abutted to the bottom wall 110 of the storage container 100, the bottom wall 110 is not deformed, and the sensing plate 200 is not driven to act. During lifting operation, the lifting weight is firstly placed in the storage container 100, the bottom wall 110 of the storage container 100 deforms under the action of weight gravity, the bottom wall 110 deforms to press the sensing plate 200, the sensing plate 200 slides downwards, and the corresponding number of triggering mechanisms 300 are driven to trigger according to the sliding distance after the sensing plate 200 slides downwards. For the triggered triggering mechanism 300, the triggering mechanism is changed from the locking state to the unlocking state, and the controlled balancing weight 400 is not limited by the triggering mechanism 300 any more so as to be capable of moving downwards; for the non-triggered trigger mechanism 300, it is still in a locked state, which still limits downward movement of the weight 400. At this time, due to the number of the triggering mechanisms 300 to be triggered and the weight of the weight to be lifted, the weight of the weight 400 capable of moving downwards is approximately equal to the weight of the weight to be lifted by reasonably setting the weight of the weight 400. Therefore, in the lifting stage, the driving motor can drive the heavy object to lift with minimum power; in the idle descent phase, the driving motor only drives the balancing weight 400 of minimum mass to rise.
For the fixed balancing weight 400, assuming that the lifting height is 10m, the weight 400 is 1000kg, the weight to be lifted is 500kg, and in a complete lifting process, the total work of the driving motor is as follows: lifting phase 10m (1000 kg-500 kg) 10N/kg + idle descent phase 10m 1000kg 10N/kg = 150KJ.
For the device in the application, the lifting height is 10m, the weight to be lifted is 500kg, and in a complete lifting process, the total work of the driving motor is as follows: lift phase 10m (500 kg-500 kg) 10N/kg + idle descent phase 10m 500kg 10N/kg = 50KJ.
Obviously, the mechanical lifting counterweight device of the application can reduce energy loss during lifting operation.
In short, by arranging the balancing weight 400 and the triggering mechanism 300, the total mass of the balancing weight 400 is approximately the same as the mass of the weight to be lifted, so that the energy loss in the lifting operation is reduced, the energy is saved, and the lifting efficiency is improved.
It should be noted that, for the mechanical lifting counterweight device according to the embodiment of the 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, i.e. the counterweight 400 is located at the lowest position of the whole device, the counterweight 400 needs to be lowered continuously when the storage container 100 is lifted, and therefore, the counterweight 400 needs to have enough lowering space. Based on the above, the mechanical lifting counterweight device in the embodiment of the invention is particularly suitable for lifting operation of an intermediate layer in building construction, a large number of weights are moved to the intermediate layer by a tower crane or other large-scale lifting equipment, and then small numbers of weights are lifted to other layers in a dispersed manner by the device; or enough shafts for the balancing weights 400 to descend are reserved in advance below the installation foundation of the mechanical lifting weight device.
Further, as shown in fig. 2 and 5, the sensing plate 200 may also deflect around its own center on the basis that the sensing plate 200 may slide up and down. For the outer periphery of the sensing plate 200, its movement in the vertical direction can be decomposed into: 1. the entire sensing plate 200 slides up and down; 2. rotation of sensing plate 200 about its own center of gravity causes the outer periphery of sensing plate 200 to move up and down relative to the center of gravity. For example, the left half of sensing plate 200 moves downward relative to the center of sensing plate 200, then the distance of movement of the left half of sensing plate 200 is the distance that sensing plate 200 moves downward as a whole plus the distance that sensing plate 200 deflects downward relative to the center of sensing plate 200; and the distance the right half of the sensing plate 200 moves downward is the distance the sensing plate 200 moves downward as a whole minus the distance the right half of the sensing plate 200 deflects upward relative to the center of the sensing plate 200.
Obviously, 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 reduced, compared to the sensing plate 200 that cannot deflect, so that the number of triggering mechanisms 300 that can be triggered by the left half of the sensing plate 200 with a larger lowering distance is larger, and the number of triggering mechanisms 300 that can be triggered by the right half of the sensing plate 200 with a smaller lowering distance is smaller.
When the mass distribution of the weight placed in the magazine 100 is not uniform, the posture of the entire magazine 100 during the ascent is caused to deflect. By providing the sensing plate 200 to be rotatable, there are more triggering mechanisms 300 that can be triggered on the side with more mass distribution, and there are more balancing weights 400 that can be triggered on the side with less mass distribution, and fewer triggering mechanisms 300 that can be triggered on the side with less mass distribution, and fewer balancing weights 400 that can be triggered on the side, the defects of the magazine 100 due to deflection itself can be reduced/eliminated.
In order to realize deflection of the sensing plate 200, a mounting column is arranged on a mounting basis, the top end of the mounting column is movably connected with the sensing plate 200, and the movable connection can be a spherical hinge in the illustration or other connection modes as long as the sensing plate 200 can deflect relative to the center of the sensing plate.
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 provided on the trigger plate 310, and trigger blocks 320 are slidably provided in the trigger slots 312; when in the locking state, the trigger block 320 protrudes from the trigger slot 312 and stops the balancing weight 400; in the unlocked state, trigger block 320 is retracted within trigger slot 312. The trigger mechanism 300 comprises a threaded shaft 330, a transmission gear 332 and a transmission rack 334, wherein 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; the trigger block 320 is driven to move as the drive rack 334 moves.
Specifically, as shown in the figure, the trigger disc 310 in this embodiment is a circular disc body, and the number of the trigger slots 312 is plural and uniformly distributed around the rotation center of the trigger disc 310. Wherein, a trigger block 320 is disposed in a portion of the trigger slots 312, which is staggered with the trigger slots 312 in which no trigger block 320 is disposed in the trigger slots 312, and the trigger slots 312 in which the trigger block 320 is disposed and the trigger slots 312 in which no trigger block 320 is disposed. In the initial state, the threaded shaft 330 is at an upper limit position, the upper end of the threaded shaft 330 abuts against the lower end surface of the sensing plate 200, and the driving rack 334 is located at the trigger slot 312 where the trigger block 320 is not located. The sensing 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, the trigger groove 312 without the trigger block 320 moves towards the trigger groove 312 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 this process, the falling distance of the sensing plate 200 is positively correlated with the weight of the weight to be lifted, the falling distance of the threaded shaft 330 is identical to the falling distance of the sensing plate 200, the number of turns of the driving gear 332 is positively correlated with the falling distance of the threaded shaft 330, the moving distance of the driving rack 334 is positively correlated with the number of turns of the driving gear 332, the number of triggers of the trigger mechanism 300 is positively correlated with the moving distance of the driving rack 334, and the number of balancing weights 400 participating in the lifting operation is identical to the number of triggers of the trigger mechanism 300. That is, the number of weights 400 involved in the lifting operation is positively correlated with the weight of the weight to be lifted.
It should be understood that, in this embodiment, the trigger plate 310 is a circular ring-shaped plate body, and accordingly, the sensing plate 200, the storage container 100, etc. are all in the shape of a disc, a cylinder, etc. Of course, the trigger plate 310 may also be a rectangular plate body, and the sensing plate 200, the storage container 100, etc. may be correspondingly rectangular.
In one embodiment, a first pushing inclined plane 321 is arranged on the upper surface of the trigger block 320, and when the transmission rack 334 moves, the first pushing inclined plane 321 is pushed and the trigger block 320 is driven to move to the unlocking position; a second pushing inclined plane 322 is arranged on one side surface of the trigger block 320, which is opposite to the trigger disc 310, and the balancing weight 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 resilient member is provided between the trigger block 320 and the trigger plate 310, which first resilient member always moves the trigger block 320 towards the locking position or has a tendency to move.
In the lifting process, the transmission rack 334 moves to push the first pushing inclined plane 321, so that the trigger block 320 moves from the locking position to the unlocking position, and at this time, the storage container 100 rises and the balancing weight 400 descends. The magazine 100 is lifted, the sensing plate 200 is reset upwards, the driving rack 334 is reset, and the trigger block 320 is returned from the unlocking position to the locking position under the action of the first elastic member. In the no-load descending process, the balancing weight 400 ascends, when the balancing weight 400 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 balancing weight 400 continues to ascend to the position above the trigger block 320 and is out of 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 piece. In short, by providing the second pushing inclined surface 322 and the first elastic member, the trigger block 320 does not limit the lifting of the balancing weight 400.
In one embodiment, for the sensing plate 200 capable of moving up and down and rotating around the center thereof, one end of the threaded shaft 330, which is close to the sensing plate 200, abuts against the lower end surface of the sensing plate 200, and a second elastic member is further disposed between the threaded shaft 330 and the mounting base, and the elastic force of the second elastic member always makes one end of the threaded shaft 330 abut against the lower end surface of the sensing 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 telescoping 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 sensing plate 200, one end of the transverse connecting rod is connected to the longitudinal connecting rod, and the other end 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 movement in the up-down direction but also movement in the horizontal direction. At this time, the sliding of the connection in the up-down direction is transmitted to the screw shaft 330 through the longitudinal connecting rod and the transverse connecting rod, and the sliding of the connection in the horizontal direction is converted into the sliding of the longitudinal connecting rod in the horizontal direction and the expansion and contraction of the transverse connecting rod, without affecting the screw shaft 330.
In one embodiment, the storage container 100 further comprises a sealing cover 120, and the storage container 100 is located in the sealing cover 120, so as to protect the safety of the lifting operation.
In one embodiment, as shown in fig. 6, a connecting rope 410 is connected to the balancing weight 400, the connecting rope 410 is connected to the storage container 100 through a winding wheel 420, and a coil spring is disposed in the winding wheel 420. For the balancing weight 400 which does not participate in the operation therein, the connecting rope 410 connected with the balancing weight is gradually loosened during the ascending process of the storage container 100, and the loosened connecting rope 410 is wound by the winding wheel 420, so that the phenomenon that the connecting rope 410 is in a disordered state too much after being loosened to influence the operation therein is avoided. For the counterweight 400 involved 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 smaller than the force for promoting the connecting rope 410 to keep in a tight state, at this time, 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 weight 400 is adjustable in mass, thereby enabling adjustment of the lifting range and accuracy of the mechanical lifting weight device.
In the above embodiment, in order to enable the sensing plate 200 to restore the original position after being separated 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 moves the sensing plate 200 upward or has a tendency to move upward.
In the above embodiment, 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 restoration, such as elastic bars, shock absorbing hydraulic cylinders, and the like.
The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The foregoing examples illustrate only a few embodiments of the invention and are described in detail herein without thereby limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.

the balancing weights are the same as the triggering mechanism in number, and are connected with connecting ropes which are connected to the storage container through winding wheels;
The triggering mechanism is provided with a corresponding locking state and unlocking state before and after triggering, and the triggering mechanism limits the downward movement of the balancing weight when the triggering mechanism is in the locking state; when the weight is in the unlocking state, the trigger mechanism does not limit the downward movement of the weight;
The trigger mechanism comprises a trigger disc, a plurality of trigger grooves are formed in the trigger disc, and trigger blocks are slidably arranged in the trigger grooves; when in the locking state, the trigger block protrudes out of the trigger groove and stops the balancing weight; when the trigger block is in the unlocking state, the trigger block is retracted into the trigger groove;
the trigger mechanism comprises a threaded shaft, a transmission gear and a transmission rack, the induction plate slides along the vertical direction to drive the threaded shaft to synchronously slide, the gear is in threaded connection with the threaded shaft, and the transmission gear is meshed with the transmission rack;
When the transmission rack moves, the trigger block is driven to move;
When in lifting operation, the lifting weight is firstly placed in the storage container, the bottom wall of the storage container deforms under the action of the weight gravity, the bottom wall is pressed against the induction plate after deformation, the induction plate slides downwards, and the corresponding number of triggering mechanisms are driven to trigger according to the sliding distance after the induction plate slides downwards; for a triggered triggering mechanism, the triggering mechanism is changed from a locking state to an unlocking state, and a balancing weight controlled by the triggering mechanism is not limited by the triggering mechanism any more so as to be capable of moving downwards; for an unactuated trigger mechanism, it is still in a locked state, which still limits downward movement of the weight; at the moment, the weight of the balancing weights which can move downwards is approximately equal to the weight of the lifted weight by reasonably setting the weight of the balancing weights due to the number of the triggering mechanisms and the weight of the weight to be lifted; therefore, in the lifting stage, the driving motor can drive the heavy object to lift with minimum power; in the no-load descending stage, the driving motor only drives the balancing weight with the minimum mass to ascend.
2. The mechanical lifting weighting device of claim 1, wherein the sensing plate is deflectable about its own center.
3. The mechanical lifting counterweight device according to claim 1, wherein a first pushing inclined plane is arranged on the trigger block, and the first pushing inclined plane is pushed and driven to move towards the unlocking state when the transmission rack moves; a first elastic member is arranged between the trigger block and the trigger disc, and the first elastic member always enables the trigger block to move towards the locking state or has a trend of moving.
4. The mechanical lifting counterweight according to claim 1 wherein the trigger mechanism includes a longitudinal connecting rod and a transverse connecting rod, one end of the longitudinal connecting rod is movably connected to the bottom of the sensing plate, one end of the transverse connecting rod is connected to the longitudinal connecting rod, and the other end is fixedly connected to the threaded shaft.
5. The mechanical lifting weighting device of claim 1 further comprising a closure within which the storage vessel is located.
6. The mechanical lifting counterweight of claim 1, wherein the counterweight is adjustable in weight.
