Embodiment Construction
[0037] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0038] The cage of the existing construction elevator is equipped with a transmission mechanism, and a rack is installed on the standard joint. The cage moves up and down along the standard joint through the transmission mode of the rack and pinion. After the cage reaches the ground, the cage must cut off the power supply. A preferred embodiment of the present invention provides a power supply device for a construction hoist, which is used for supplying power to an auxiliary electronic system provided in the car when the car is dropped to the ground. refer to figure 1 , in this embodiment, the construction hoist includes: a standard section 1, a bottom cage 2 fixedly arranged on the ground and a hoisting cage 9 that moves up and down along the stan...

The invention discloses a power supply device of a construction lifter. The power supply device comprises a first sensing unit and a second sensing unit. The first sensing unit comprises a power supply adjusting unit and a transmitting coil electrically connected with the output end of the power supply adjusting unit, the power supply adjusting unit is used for converting mains supply provided by a bottom-cage distribution box to high-frequency power, and the transmitting coil is used for converting high-frequency power to an alternating magnetic field. The second sensing unit comprises a receiving coil arranged on a cage and a demodulation unit electrically connected with the receiving coil, the receiving coil is used for generating sensing electromotive force, and the demodulation unit is used for converting sensing electromotive force which is rectified and voltage-stabilized to stabilized-voltage power and providing the stabilized-voltage power for electric equipment. According to the power supply device, the first sensing unit arranged on a bottom cage and the second sensing unit arranged on the cage are used for supplying power in a high-frequency electromagnetic sensing mode when the cage reaches the ground, the requirement for supplying power for the electric equipment in the cage of the construction lifter at a landing point is met, and therefore intelligent monitoring reliability of the construction lifter is improved.
Description
technical field [0001] The invention relates to the field of control of construction elevators, in particular to a power supply device for construction elevators. Background technique [0002] With the continuous development of my country's construction industry and the continuous improvement of the level of construction mechanization, the technical requirements and safety requirements for construction lifting equipment are also getting higher and higher. The construction hoist includes a fence fixed on the ground, which is called a bottom cage in the industry, and an iron cage that can carry people that moves up and down with the standard section is called a hanging cage in the industry. The hanging cage is equipped with a transmission mechanism, and gears are installed on the standard section. The cage runs up and down on the standard section through the rack and pinion transmission mode. All control systems and other electronic devices are installed in the cage. The power...
