Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] Such as figure 1 As shown, the self-unloading energy-saving construction elevator mechanical device includes a cage 1, a motor 2, a frequency converter 3, a transmission mechanism 4, a wire rope 5, a sky wheel 6, a frame body 7, and a counterweight 8. The transmission mechanism 4 includes a gear set 41 with a variable transmission ratio and a rack 42 meshing with an output gear 418 of the gear set 41 .

[0025] A motor 2 , a frequency converter 3 and a gear set 41 are cooperatingly arranged on the hanging cage 1 . Motor 2, frequency converter 3 and gear set 41 rise and fall with the lifting of hanging cage 1.

[0026] The motor 2 is the power unit of the whole device. As a preference, the motor 2 only includes one driving motor, which cooperates with the gear set 41, and can effectively operate through the transformation of the gear set 41, and when...

Abstract

A self-discharging energy-saving mechanical device of a construction hoist belongs to the technical field of construction hoisting equipment and comprises a cage, a motor, a transmission mechanism, a steel wire rope, a hoisting sheave, a rack and a counter weight. The counter weight is connected with the cage via the steel wire rope wound through the hoisting sheave, the transmission mechanism comprises a gear bank and a rack, the transmission ratio of the gear bank can be changed, the rack is meshed with an output gear of the gear bank, and an input end of the transmission mechanism is connected with an output shaft of the motor in a matched manner. The single-drive motor can be used, saves production cost, and further greatly saves energy as compared with a two-drive or three-drive motor. The transmission mechanism is exquisite in design, the transmission ratio can be changed, and accordingly applicability of the self-discharging energy-saving mechanical device is increased. When in assembling and disassembling, a speed shifting mechanism is changed by means of changing the gear bank, so that the construction hoist can effectively operate.

Description

technical field [0001] The invention belongs to the technical field of construction hoisting equipment, and in particular relates to a mechanical device of a self-unloading energy-saving construction hoist. Background technique [0002] The construction hoist is a commonly used construction machine for carrying people and cargo on construction sites. The application of construction elevators improves the production efficiency of construction and saves the labor time of workers. It plays an increasingly important role in multi-storey and high-rise construction sites. [0003] The transmission mechanism of the traditional construction elevator mainly adopts the motor reduction mechanism, which is characterized in that the motor drives the gear for rotary motion, the gear and the rack are meshed, and the gear moves linearly on the rack to drive the hoisting cage. The motors of common construction elevators adopt three-drive, two-drive and single-drive. [0004] The three-driv...
