Description

Technical Field

[0001] The utility model relates to the technical field of tower lifting equipment, in particular to a tower lifting device. Background Art

[0002] In the process of construction engineering, tower lifting equipment is needed to lift building materials. The utility model patent with patent application number CN202310330491.5 discloses a tower lifting device. The rotation of the counterweight block and the adjustment of the distance between the counterweight block and the adjusting arm can adjust the position of the counterweight block so as to be applicable to more environments and increase the use range of the device. At the same time, the reaction force of the coil spring and the friction resistance between the side wall of the mounting block and the inner wall of the buffer block are used to achieve the buffering effect of the hoisted object. According to the technical scheme disclosed by the utility model, when the existing tower lifting device is used, on the one hand, it cannot automatically adjust the position of the counterweight according to the torque applied to the cross arm, which is not conducive to effectively ensuring the force balance of the tower frame, and thus is not conducive to ensuring the working safety of the tower frame. On the other hand, when the position of the counterweight is adjusted by the screw rod, the screw rod is easily rusted due to rain or damaged by the inertial impact of the counterweight, which is not conducive to ensuring the safety of the screw rod.

[0003] Therefore, how to design a tower lifting device has become our current problem to be solved. Utility Model Content

[0008] Furthermore, the screw rod is installed on the top of the crossbeam, and one end of the screw rod passes through the support block through a bearing and is key-connected to the output shaft of the motor.

[0009] Furthermore, a slot is provided on the inner side of the sleeve, the bottom of the push plate is clamped on the inner side of the slot, both sides of the bottom of the push plate are connected to the inner wall of the slot through springs, the top of the push plate is sleeved on the outer side of the screw rod, and a roller is installed on the inner side of the sleeve, and the roller is clamped on the top of the beam.

[0010] Furthermore, an external thread is provided on the outer side of the screw rod, and an internal thread is provided on the inner side of the push plate. The external thread matches the internal thread. The outer side of the screw rod is sleeved on a telescopic tube. One end of the telescopic tube is bonded to the push plate, and the other end of the telescopic tube is respectively bonded to the support block and the tower.

[0011] Furthermore, the piezoelectric ceramics are mounted on the bottom of the base by bolts, the piezoelectric ceramics are mounted on the four sides of the base respectively, and the voltmeter is mounted on the inner side of the base by bolts.

[0013] Beneficial effects: 1. When the tower lifting device is working, when the crane is used to lift the goods, the base at the bottom of the tower generates different pressures on different piezoelectric ceramics due to the lifting and moving of the goods, which makes the piezoelectric ceramics generate different voltages. After the voltmeter is subjected to the voltage difference of different piezoelectric ceramics, the pointer on the voltmeter deflects, which makes the pointer squeeze the touch-pressure switch, and the touch-pressure switch turns on the motor. The motor drives the push plate through the screw rod, and the push plate drives the frame to move on the beam through the roller, thereby adjusting the position of the counterweight on the beam until the forces on both sides of the tower are balanced, thereby effectively improving the stability of the tower, preventing damage due to unstable forces on the tower, and ensuring the safety of the tower.

[0014] 2. When the tower lifting device is in use, the telescopic tube sleeve is arranged on the outside of the screw rod to prevent rain from reaching the outer side of the screw rod, thereby effectively preventing the screw rod from rusting due to rain and ensuring the service life of the screw rod. At the same time, the telescopic tube can be telescoped according to the position of the push plate. When the screw rod pushes the push plate to move, the push plate pushes the clamping sleeve through the spring. At the same time, the push plate moves on the inner side of the slot. When the screw rod stops rotating, the counterweight drives the clamping sleeve to continue moving under the action of inertia. The clamping sleeve squeezes the push plate through the spring and slows down under the elastic force of the spring until the counterweight stops moving, effectively reducing the impact force of the counterweight on the screw rod and ensuring the safe use of the screw rod.

During operation, when the crane 4 is used to lift the goods, the base 2 at the bottom of the tower 1 generates different pressures on different piezoelectric ceramics 15 due to the lifting and moving of the goods, thereby making the piezoelectric ceramics 15 generate different voltages. After the voltmeter 16 is subjected to the voltage difference of different piezoelectric ceramics 15, the pointer on the voltmeter 16 is deflected, thereby causing the pointer to squeeze the touch-pressure switch 17, and the touch-pressure switch 17 turns on the motor 9. The motor 9 drives the push plate 12 through the screw rod 10, and the push plate 12 drives the frame 6 to move on the beam 3 through the roller 7, thereby adjusting the position of the counterweight 5 on the beam 3 until the forces on both sides of the tower 1 are balanced, thereby effectively improving the stability of the tower 1, preventing damage caused by unstable forces on the tower 1, and ensuring the safety of the tower 1.

At the same time, the telescopic tube 11 can be telescopic according to the position of the push plate 12. When the screw rod 10 pushes the push plate 12 to move, the push plate 12 pushes the card sleeve through the spring 14. At the same time, the push plate 12 moves on the inner side of the card slot 13. When the screw rod 10 stops rotating, the counterweight 5 drives the card sleeve 6 to continue to move under the action of inertia.

The tower 1 is damaged due to unstable force. To ensure the safety of the tower 1, the telescopic tube 11 is sleeved on the outside of the screw rod 10 to prevent rain from reaching the outer side of the screw rod 10, thereby effectively preventing the screw rod 10 from rusting due to rain, thereby ensuring the service life of the screw rod 10.
