Detailed Description
In order to make the technical scheme of the present application better understood by those skilled in the art, the present application will be further described in detail with reference to the accompanying drawings.
As shown in fig. 1 to 6, the construction device for energy-saving building provided by the embodiment of the application comprises a tower body 1, and a balance arm 2 and a crane arm hinged on the tower body 1, wherein a first transmission branched chain 10 is arranged at the top end of the tower body 1, the distal end of the balance arm 2 is connected with the distal end of the crane arm 3 through the first transmission branched chain 10, a lifting mechanism 30 is arranged on the crane arm 3, a storage chamber 11 is arranged on the tower body 1, a plurality of balancing weights 12 are stored in the storage chamber 11, a transfer mechanism 20 for driving the balancing weights 12 to move is arranged on the balance arm 2, a second transmission branched chain 13 is arranged between the first transmission branched chain 10 and the transfer mechanism 20, the balance arm 2 is driven to swing upwards through the first transmission branched chain 10 when the crane arm 3 is stressed downwards, and the first transmission branched chain 10 is controlled by the downwards swinging force of the crane arm 3 through the second transmission branched chain 13 to control the distance of the balancing weights 20 entering the storage chamber 11 so as to transfer the weight of at least one balancing weight 12 to adapt to the weight of a lifted object.
Specifically, when the tower crane is used, the lifting mechanism 30 on the lifting arm 3 lifts an object and drives the object to move along the length direction of the lifting arm 3 so as to move the object to a designated construction position, when the object is lifted, the lifting arm 3 mainly bears the gravity of the object, so that the common gravity of the lifting arm 3 and the object can bring a rolling force to the tower body 1, for balancing the gravity, the balance arm 2 is further arranged on the tower body 1, and the balance arm 2 is provided with the balancing weight 12, so that the gravity of the balance arm 2 and the balancing weight 12 and the gravity of the lifting arm 3 and the lifting object can be balanced by taking the tower body 1 as a boundary line, and the rolling force generated by the tower body 1 on one side of the lifting arm 3 is balanced by the rolling force of the balance arm 2 and the balancing weight 12 on the other side, namely, according to the force balancing principle, the condition that the balancing weight 12 and the object are fixed, the length of the balancing weight arm is changed, so that the balancing mechanism 20 arranged in the embodiment of the application can drive the balancing weight 12 to move on the balance arm 2, and the lifting mechanism 30 can drive the object to move on the two sides of the lifting arm 3 to realize the balancing force.
In addition, the gravity of the object lifted by the lifting mechanism 30 is not fixed, and the gravity of the balancing weight 12 arranged on the balance arm 2 is adjusted accordingly, so in the embodiment of the application, the balance arm 2 and the lifting arm 3 are both arranged in a structure capable of swinging, the distal ends of the balance arm 2 and the lifting arm 3 are connected through the first transmission branched chain 10, when in operation, the lifting arm 3 is subjected to the influence of the gravity of the object to generate a lower pendulum, the swinging of the lifting arm 3 drives the first transmission branched chain 10 to move together, the first transmission branched chain 10 transmits the power to the balance arm 2, and the balance arm 2 swings upwards.
In the process of transmitting power, the first transmission branched chain 10 is equivalent to transmitting displacement, but in the lifting range of the tower crane, the lower swing amplitude of the lifting arm 3 is limited by the first transmission branched chain 10, and the swing speed is also limited by the first transmission branched chain 10, so as to avoid damage to the tower crane caused by too high swing speed of the swing amplitude of the lifting arm 3, therefore, in the embodiment of the application, the first transmission branched chain 10 comprises a first chute 100 arranged at the top end of the tower body 1, a first sliding block 101 is horizontally and dynamically arranged in the first chute 100, a first elastic piece is connected between one end of the first chute 100 and one end of the first sliding block 101, the first chute 100 horizontally slides and penetrates through a first connecting rod 102, the distal end of the balance arm 2 is connected with one end of the first connecting rod 102 through a first inhaul cable 103, the distal end of the lifting arm 3 is connected with the other end of the first connecting rod 102 through a second inhaul cable 104, and when the lifting arm 3 does not lift an object, the lifting arm 2 is in a horizontal state.
When the boom 3 swings down, the second stay cable 104 drives the first connecting rod 102 and the first sliding block 101 to move together in the first sliding groove 100 in the direction away from the balance arm 2, so that the first sliding block 101 presses the first elastic piece, the first elastic piece is pressed and elastic force is increased, the swing speed of the boom 3 is limited, when the gravity of the object lifted by the boom 3 is increased, the first elastic piece is compressed more and the elasticity is larger, when the gravity of the object lifted by the boom 3 reaches the maximum in the limit range, the first sliding block 101 is completely stuck on one side, close to the boom 3, of the first sliding groove 100, and therefore the first sliding groove 100 limits the first sliding block 101, namely limits the swing amplitude of the boom 3.
When the first transmission branched chain 10 moves, the second transmission branched chain 13 is driven to move together, the movement of the second transmission branched chain 13 drives the transfer mechanism 20 to enter the storage chamber 11, the gravity of the lifting object of the lifting arm 3 is different, the swing amplitude of the lifting object is also different, so that the distance of the second transmission branched chain 13 driving the transfer mechanism 20 to enter the storage chamber 11 is long or short, the weight of the balancing weight 12 taken away from the storage chamber 11 by the transfer mechanism 20 can be controlled to a certain extent, redundant balancing weights 12 are always stored in the storage chamber 11, and when the lifting device is not operated, all the balancing weights 12 are stored in the storage chamber 11, so that the gravity borne by the tower body 1 can not have deflection problem.
The embodiment of the application has the beneficial effects that:
firstly, when the lifting arm 3 is swung downwards by the gravity of a lifted object, the balance arm 2 is driven to swing upwards by the first transmission branched chain 10, the first transmission branched chain 10 can drive the second transmission branched chain 13 to move together by the swinging force of the lifting arm 3, then the second transmission branched chain 13 can drive the transfer mechanism 20 to enter the storage chamber 11, the distance of the transfer mechanism 20 entering the storage chamber 11 is related to the swinging amplitude of the lifting arm 3, and then the transfer mechanism 20 can transfer the balancing weight 12 with proper weight to adapt to the weight of the lifted object, so that the weight of the balancing weight 12 on the balance arm 2 can be adjusted according to the weight of the lifted object.
Secondly, during operation, the weight of the balancing weight 12 moved out of the storage chamber 11 by the transfer mechanism 20 is adapted to the weight of the lifted object, and when not in operation, the transfer mechanism 20 can move the balancing weight 12 into the storage chamber 11 again, so that the gravity of the tower crane does not deviate first when the tower crane is in operation.
Preferably, a second sliding groove 110 is provided on a side wall of the storage chamber 11, a plurality of second sliding blocks 111 are horizontally and dynamically provided in the second sliding groove 110, a plurality of second sliding blocks 111 are in one-to-one correspondence and fixedly connected with a plurality of balancing weights 12, one end of the second sliding groove 110, which faces the balancing arm 2, is of an opening structure, and a first locking mechanism 4 is provided in the balancing weights 12.
When not in operation, the second sliding groove 110 and the second sliding block 111 are locked by the first locking mechanism 4.
In operation, the transfer mechanism 20 enters the storage chamber 11, and the first locking mechanism 4 unlocks the second slide groove 110 and the second slider 111.
In particular, no matter whether the tower crane works or not, the weight of the balancing weight 12 needs to be stably placed at any position, so that in order to facilitate the transfer mechanism 20 to enter the storage chamber 11 and smoothly take away the balancing weight 12, the second sliding chute 110 and the second sliding block 111 provided in the embodiment of the application can jointly limit the position of the balancing weight 12, so that the balancing weight 12 can be moved out of the storage chamber 11 along the horizontal direction under the driving of the transfer mechanism 20, and the first locking mechanism 4 is further arranged between the second sliding chute 110 and the second sliding block 111, in the process of the tower crane work, not only needs to lift objects with different weights, but also can send the objects to a designated position, in the process, the tower crane itself also needs to rotate, because of inertia, a certain degree of shaking and tilting of the tower body 1 can occur, and if the second sliding chute 110 and the second sliding block 111 are used singly, the weight of the balancing weight 12 is limited, and the limiting behavior is obviously unrealistic because of the weight of the balancing weight 12, in the embodiment of the application, the first locking mechanism 4 comprises a first extrusion member 40 arranged in the balancing weight 12, and when the first extrusion member 40 is pressed by the first extrusion member 40 in the first sliding member 40, and the second extrusion member 40 is pressed by the first sliding member 40 and the first sliding member 40 is not pressed by the first sliding member 41, and the second extrusion member 41 is contacted with the first sliding member 41, and the first sliding member 41 is contacted with the first extrusion member 41, and the second extrusion member 41 is limited by the first sliding member 41, and the first sliding member is not pressed by the first sliding member 41 and the first extrusion member 41, the friction between the second runner 110 and the transfer mechanism 20 is reduced so that the weight 12 can be smoothly carried away.
The first extrusion member 40 may be preferably disposed such that first extrusion rods 400 are disposed on both sides of the balancing weight 12 (along both sides of the transfer mechanism 20 in the moving direction in the storage chamber 11), the balancing weight 12 and the first extrusion rods 400 are horizontally slidingly connected, a third elastic member is disposed between the first extrusion rods 400 and the balancing weight 12, then two friction blocks (i.e., first friction members 41) are slidably disposed on the second sliding block 111, one end of each friction block, far away from the second sliding groove 110, is provided with a wedge surface, each first extrusion rod 400 is mounted with a first extrusion block 401, the two first extrusion blocks 401 are in one-to-one correspondence with the two friction blocks, and the first extrusion blocks 401 are also in a wedge structure, so that under the action of the third elastic member, the first extrusion rods 400 drive the first extrusion blocks 401 to extrude the friction blocks, so that the friction blocks are in frictional contact with the inner walls of the second sliding groove 110, and the transfer mechanism 20 can drive the first extrusion blocks 401 to move towards the direction of the non-extrusion blocks through the first extrusion rods 400, so that the friction blocks and the friction blocks between the friction blocks and the inner walls 110 are reduced.

When the balance arm 2 is in the horizontal state, the triggering piece 203 triggers the second locking mechanism 6 to lock the second connecting rod 201 and the third sliding groove 202.
Specifically, when the counterweight 12 is stored in the storage chamber 11, the counterweight 12 needs to be transferred to the balance arm 2 by transferring to balance the gravity borne by the boom 3, when the counterweight is not operated, the driving assembly firstly brings the frame 200 to a part of the storage chamber 11, then the driving assembly stops working, but the driving assembly does not obstruct other driving mechanisms to drive the frame 200 to move, i.e. the frame 200 does not extend into the storage chamber 11 completely, for example, the total length of the frame 200 is 5m, the counterweight can extend into the storage chamber 1130cm first, because the third chute 202 is arranged on the frame 200, if the third chute 202 is fixedly connected to the frame 200, the upper swing of the balance arm 2 drives the frame 200 to swing together through the second connecting rod 201 on the driving assembly, and the storage chamber 11 for storing the counterweight 12 is not suitable to be movably arranged on the tower 1, so that the risk of instability is brought to the tower 1.
