The electric drive module A32, the electric drive module B46 and the electric drive module C49 of the present invention all adopt the prior art, and the electric drive module A32, the electric drive module B46 and the electric drive module C49 all consist of a speed reducer, an electric motor and a control unit.
The pressure sensor 18 of the present invention is known in the art.
The working process of the invention is as follows: in the initial state, the L-plate 10 is retracted to the extreme position on the support plate 8, and the return spring 14 is in the extended state. The top end of the L-plate 10 is lower than the height of the steel bar frame 1.
Firstly, a steel template 3 is hoisted by a tower crane and horizontally arranged on one side of a cast-in-situ wall body reinforcing steel bar frame 1 on a construction floor, and an auxiliary block 2 is matched between the steel template 3 and the root part of the reinforcing steel bar frame 1, so that the steel template 3 has a space between the steel bar frame 1 after being erected, and the reinforcing steel bar frame 1 is completely positioned in a wall body after being poured conveniently.
When the steel formwork 3 is erected by using the invention, the electric driving module C49 is started to drive the winding wheel 47 to pay the steel wire rope 5 for a sufficient length and to move the free end of the steel wire rope 5 over the steel formwork 3 side of the steel frame 1, then the invention is moved to the other side of the steel frame 1 to make the two wedge blocks 23 approach the steel frame 1 along the direction perpendicular to the wall surface of the steel frame 1, the inclined surfaces of the two wedge blocks 23 drive the L-shaped plate 10 and the pull rod 15 to move vertically upwards relative to the supporting plate 8 under the action of the top end of the steel frame 1, the return spring 14 is further stretched, and the limit block 12 is separated from the upper end of the supporting plate 8.
As the present invention continues to approach the steel reinforcing frame 1, when the two wedge-shaped blocks 23 simultaneously pass over the top end of the steel reinforcing frame 1, the L-shaped plate 10 is instantaneously dropped relative to the support rod 26 and supported by the support plate 8 under the restoring action of the restoring spring 14, and the stopper 12 approaches the upper end of the support plate 8, at this time, the four universal wheels 7 on the base 6 are locked to fix the position of the base 6 of the present invention, and the free end of the wire rope 5 is connected with the hanging ring 4 at the distal end of the steel formwork 3, and the wire rope 5 is in a loose state.
The control system controls the electric drive module C49 to operate, the electric drive module C49 drives the winding wheel 47 to rotate, the winding wheel 47 winds the steel wire rope 5 connected with the hanging ring 4 on the steel template 3, the steel wire rope 5 is gradually straightened, and the steel template 3 swings upwards around the contact point of the steel wire rope 5 and the auxiliary block 2 to be erected.
When the steel wire rope 5 is just stretched and the steel formwork 3 is still in a horizontal state, the inclination angles of the two portions of the steel wire rope 5 on the two sides of the fixed pulley A22 may not be equal. If the inclination angle of the wire rope 5 at the side of the movable pulley A27 of the fixed pulley A22 is smaller than the inclination angle of the wire rope 5 at the side of the steel template 3 of the fixed pulley A22, the tension unbalance of the wire rope 5 at the two sides on the two sides of the fixed pulley A22 is caused, so that the fixed pulley A22 drives the abutting block 19 to press the pressure sensor 18 close to the fixed pulley A22 in the fixed seat 17 through the U seat A21 and the supporting block 20, the pressure sensor 18 which is pressed transmits the generated pressure electric signal to the control system, the control system controls the electric drive module A32 and the electric drive module B46 to operate simultaneously, the electric drive module A32 drives the sliding seat A25 to move vertically and downwards in the guide seat A24 through the bevel gear A31, the bevel gear B30 and the two mutually driveably connected screws A28, the inclination angle of the wire rope 5 at the side of the movable pulley A27 of the fixed pulley A22 is increased rapidly and is equal to the inclination angle of the wire rope 5 at the side of the steel template 3 of the fixed pulley A22, so that the two sides of the fixed pulley A22 reach the balance, the stress on the two sides of the pressing block 19 is balanced, so that the tension on the two sides of the steel bar frame 1 generated by pulling the steel wire ropes 5 is indirectly balanced, the steel bar frame 1 cannot be deformed or inclined due to unbalanced stress on the two sides, and the steel bar frame 1 is protected from being damaged.
When the movable pulley a27 vertically moves downwards, the part of the steel wire rope 5 between the fixed pulley a22 and the winding wheel 47 tends to be loosened, so that the steel wire rope 5 is always kept in a straightening and effective pulling state for the steel formwork 3 at this time, the electric driving module B46 drives the sliding seat B37 to vertically move upwards through the bevel gear C45, the bevel gear D44, the ring sleeve 43, the internal thread sleeve 42 and the screw B41, and the sliding seat B37 drives the movable pulley B40 to quickly tighten the steel wire rope 5 through the U seat C39.
When the steel wire ropes 5 are just straightened and the steel formwork 3 is in a horizontal state, if the inclination angle of the steel wire ropes 5 on the side of the movable pulley A27 of the fixed pulley A22 is larger than that of the steel wire ropes 5 on the side of the steel formwork 3 of the fixed pulley A22, the tension unbalance of the steel wire ropes 5 on the two sides of the fixed pulley A22 can be caused, so that the fixed pulley A22 drives the pressing block 19 to press the pressure sensor 18 in the fixed seat 17 close to the steel formwork 3 through the U seat A21 and the supporting block 20, the pressed pressure sensor 18 transmits a generated pressure electric signal to the control system, the control system controls the electric drive module A32 and the electric drive module B46 to operate simultaneously, the electric drive module A32 drives the A25 to move vertically and quickly upwards in the guide seat A24 through the bevel gear A31, the bevel gear B30 and the two mutually and mutually drivenly connected screws A28, the inclination angle of the steel wire ropes 5 on the side of the movable pulley A27 of the fixed pulley A22 is reduced quickly and is equal to that of the steel wire ropes 5 on the side of the fixed pulley A22, so that the stress on the two sides of the fixed pulley A22 reaches balance rapidly, the stress on the two sides of the pressing block 19 reaches balance, and the tension generated by the pulling of the steel wire ropes 5 on the two sides of the steel bar frame 1 indirectly reaches balance, so that the steel bar frame 1 cannot deform or incline due to the unbalanced stress on the two sides, and the steel bar frame 1 is protected from being damaged.
At the same time of the vertical upward movement of the movable pulley A27, the part of the steel wire rope 5 between the fixed pulley A22 and the winding wheel 47 is also tensed, so in order to ensure that the steel wire rope 5 does not block the vertical upward movement of the movable pulley A27, the electric drive module B46 drives the sliding seat B37 to vertically move downwards through the bevel gear C45, the bevel gear D44, the ring sleeve 43, the internal thread sleeve 42 and the screw B41, and the sliding seat B37 drives the movable pulley B40 to quickly discharge and supplement the tensed steel wire rope 5 through the U seat C39.
With the continuous pulling and standing of the steel formwork 3 by the steel wire rope 5 continuously wound by the winding wheel 47, in the process that the steel formwork 3 is pulled by the steel wire rope 5 to swing from the horizontal state to the vertical state, the inclination angle of the steel wire rope 5 on the steel formwork 3 side of the fixed pulley A22 is gradually changed, so that the stress on two sides of the fixed pulley A22 is unbalanced, the pressing block 19 is caused to press the pressure sensor 18 on one side in the fixed seat 17, the pressed pressure sensor 18 transmits the generated pressure electric signal to the control system, the control system continuously controls the electric driving module A32 and the electric driving module B46 to synchronously operate, the electric driving module A32 drives the movable pulley A27 to quickly adjust the inclination angle of the steel wire rope 5 on the corresponding side of the fixed pulley A22 through a series of transmissions, so that the stress on two sides of the fixed pulley A22 is quickly balanced, and meanwhile, the electric driving the fixed pulley B46 drives the fixed pulley B34 to tighten the slack of the steel wire rope 5 caused by the vertical downward movement of the movable pulley A27 or swing of the steel wire rope 5 through a series of the movable pulley A27 5 the steel wire rope 5 is tensioned for releasing and supplementing due to the vertical upward movement of the movable pulley A27.
Because the moving speed of the movable pulley A27 is twice the moving speed of the movable pulley B40, the releasing length or the tensioning length of the movable pulley B40 to the steel wire rope 5 during the moving is equal to the tensioning length or the releasing length of the movable pulley A27 to the steel wire rope 5 during the moving, so that the steel wire rope 5 is ensured not to block the moving of the movable pulley A27 or the steel wire rope 5 is ensured to be always in a tense state, and the winding wheel 47 is ensured to effectively pull the steel formwork 3 by winding the steel wire rope 5.
In the process that the steel formwork 3 is pulled by the steel wire rope 5 to be vertical, the movable pulley A27 and the movable pulley B40 move cooperatively to ensure that the stress on the two sides of the fixed pulley A22 is always kept balanced, so that the stress on the two sides of the steel bar frame 1 is always kept balanced in the installation process of the steel formwork 3, and the steel formwork 3 cannot be deformed or inclined due to unbalance of the stress on the two sides.
When the steel formwork 3 is pulled by the steel wire rope 5 to finish the erection, the control system controls the electric drive module A32, the electric drive module B46 and the electric drive module C49 to stop running. And then, the auxiliary block 2 is pulled away, the vertical steel template 3 is fixedly installed after the auxiliary block 2 is pulled away, and the steel wire rope 5 is detached from the hanging ring 4 of the steel template 3 after the steel template 3 is fixedly installed. By manually pushing the tie rod 15 upwards, the tie rod 15 via the tension spring plate 13 moves the L-plate 10 vertically upwards and away from the top end of the steel reinforcement frame 1, so that the two wedges 23 are disengaged from the top end of the steel reinforcement frame 1, and then the universal wheel 7 is unlocked and pushes the base 6 away from the steel reinforcement frame 1, so that the two wedges 23 completely pass over the steel reinforcement frame 1. When the two wedge-shaped blocks 23 completely cross the steel bar frame 1, the pull rod 15 is pulled downwards, the pull rod 15 drives the L-shaped plate 10 to reset relative to the supporting plate 8, the reset spring 14 restores to the original state, and the limiting block 12 abuts against the top end of the supporting plate 8.
In the process of erecting steel wire ropes 5 by pulling the steel templates 3, the tower crane does not need to continuously participate, the tower crane can participate in other operations in the installation process of the steel templates 3, and the utilization rate of the tower crane is effectively improved.
In conclusion, the beneficial effects of the invention are as follows: the invention erects the steel formwork 3 which is horizontally placed at one side of a steel frame 1 of a cast-in-place wall body of a construction floor by a tower crane in a mode of driving a winding wheel 47 to wind a steel wire rope 5 by an electric driving module C49 to one side of the steel frame 1, in the process of erecting the steel formwork 3, the inclination angle of the steel wire rope 5 which is horizontally placed at one side of the steel frame 1 of the construction floor by the tower crane is continuously changed by a fixed pulley A22 in the invention, so that the pulling force and the stress direction of the steel wire rope 5 at the two sides of the steel formwork 3 are continuously changed by the fixed pulley A22, the fixed pulley A22 drives a pressure-resisting block 19 to extrude a pressure sensor 18 at one side of the inner wall of a fixed seat 17 through a U seat A21 and a supporting block 20 due to the unbalance stress, the extruded pressure sensor 18 feeds back signals to the electric driving module A32 through a control system, the electric driving module A32 drives a movable pulley A27 which is installed on the sliding seat A25 to move along the direction which is vertical to the axis of the fixed pulley A22 and the axis of the fixed pulley B34 and acts on the steel wire rope 5 which the fixed pulley A22 is positioned at one side of the fixed pulley B34, the inclination angle of the steel wire rope 5 of the fixed pulley A22 positioned on one side of the fixed pulley B34 is constantly kept equal to that of the steel wire rope 5 on the other side, so that the fixed pulley A22 is always kept in stress balance on two sides in the process of installing the steel formwork 3, the two sides of the steel bar frame 1 indirectly supporting the fixed pulley A22 are further guaranteed to be in stress balance, and deformation or inclination of the steel bar frame 1 due to unbalanced stress on two sides in the process of installing the steel formwork 3 is avoided.
In the process of vertically installing the steel formwork 3, the steel formwork 3 is vertically installed by fully utilizing the existing reinforcing steel frame 1 as a support, and equipment cost is reduced without additionally adding equipment. Meanwhile, the tower crane can be withdrawn after the steel template 3 is lifted and placed on a construction floor by the tower crane, the participation of the tower crane is not needed in the whole erection installation process of the steel template 3, the use of the tower crane in other operations is not influenced, and the utilization rate of the tower crane is greatly improved.
