Description

A frequency conversion energy-saving passenger and cargo construction elevator

Technical field:

The utility model relates to a construction elevator, in particular to a frequency conversion energy-saving passenger and cargo construction elevator.

Background technique:

Construction elevators are important equipment in the construction industry and play a huge role in the construction field; with the continuous improvement of production levels, in order to save energy, save labor time, and improve labor efficiency, people have higher requirements for energy saving, performance, and efficiency of construction elevators. Higher and higher. The existing construction elevators are basically driven by electric motors and configured with double cages. The rated load of each cage is 2 tons, and the rated running speed is 35 m/min. When each cage is equipped with a counterweight, the single hoist The motor power of the cage is 22 kW. The characteristic of this kind of construction hoist is that the motor always works at the rated power. However, in actual work, the load of the construction hoist is constantly changing according to the needs. When the load of the construction hoist is less than the rated load, the power used by the construction hoist It cannot reach the rated power, so the energy consumption is relatively high to a certain extent, resulting in a waste of energy. On the other hand, the existing construction elevator works under the rated power, and under the loads of different weights, the impact of the construction elevator cage is relatively large when it starts and stops, and the riding comfort of the personnel is poor.

Invention content:

The purpose of this utility model is to provide a single motor drive under the condition of constant rated load and rated running speed, which can output different power under different weight loads, so as to realize the high power output of small power motors; There are frequency conversion energy-saving passenger and cargo construction elevators that cause energy waste when the power used by the construction elevator does not reach the rated power, and the impact force is large when starting and stopping, and the comfort of the personnel is poor.

The utility model realizes above-mentioned object through following technical scheme:

A frequency conversion energy-saving passenger and cargo construction elevator, which is composed of a hanging cage, a guide rail frame base, a guide rail frame, a driving device, a frequency conversion cabinet, an electric control box, a sky wheel, a balance weight and a transmission rack, and is characterized in that: the guide rail frame base There is a guide rail frame on the top, and the left and right sides of the guide rail frame are symmetrically installed with a transmission rack and a cage, and the drive rack is meshed with the transmission gear on the cage; The drive device is installed on the top, and the frequency conversion cabinet and the electric control box are respectively installed on the corresponding surfaces of the hanging cage on the left and right sides of the guide rail frame; the drive device is connected with the electric control box through the frequency conversion cabinet.

The utility model has the beneficial effects compared with the prior art in that:

The frequency conversion energy-saving passenger and cargo construction elevator is controlled by a frequency conversion system. Under the condition of constant rated load and rated operating speed, the motor outputs different power under different loads, realizing the high power output of the small power motor and avoiding the Existing construction elevators work under the rated power, and when the power used does not reach the rated power, it will cause energy waste; and the existing construction elevators are under different loads, and the impact of the construction elevator cage is relatively large when it starts and stops. The problem of poor riding comfort for personnel. The operation stability of the construction hoist is guaranteed, and at the same time, the construction hoist has the characteristics of simple structure, convenient installation, disassembly and maintenance, easy operation and wide application range.

In the figure: 1. Hanging cage, 2. Guide rail frame base, 3. Guide rail frame, 4. Driving device, 5. Frequency conversion cabinet, 6. Electric control box, 7. Sky wheel, 8. Balance weight, 9. Steel wire rope, 10 , Transmission rack.

Detailed ways:

The frequency conversion energy-saving passenger and cargo construction elevator consists of a hanging cage 1, a guide rail frame base 2, a guide rail frame 3, a driving device 4, a frequency conversion cabinet 5, an electric control box 6, a sky wheel 7, a balance weight 8, a steel wire rope 9 and a transmission rack 10 The guide rail frame base 2 is equipped with a guide rail frame 3, and the left and right sides of the guide rail frame 3 are respectively symmetrically installed with a transmission rack 10 and a hanging cage 1. The top of the hanging cage 1 is equipped with a driving device 4, and the driving device 4 is composed of a motor and a reduction mechanism. Composition, be provided with transmission gear (not drawn among the figure) in the speed reduction mechanism, the transmission rack 10 that the symmetrical installation of guide rail frame 3 left and right sides is respectively meshed with the transmission gear that is provided with in the speed reduction mechanism and is connected.

The sky wheel 7 is installed on the top of the rail frame 3, and the front and rear ends of the rail frame 3 are hoisted with a balance weight 8 by the wire rope 9 through the sky wheel 7, so as to balance the self weight of the hanging cage 1 to the greatest extent. A frequency conversion cabinet 5 and an electric control box 6 are respectively installed on the corresponding surfaces of the hanging cage 1 on the left and right sides of the guide rail frame 3; the driving device 4 is connected with the electric control box 6 through the frequency conversion cabinet 5 (see accompanying drawings 1-3).

When the frequency conversion energy-saving passenger and cargo construction elevator is in operation, the transmission gear of the driving device 4 moves up and down along the transmission rack 10, thereby driving the cage 1 of the construction elevator to move up and down. The operation of the frequency conversion energy-saving passenger and cargo construction elevator is controlled by the frequency conversion cabinet 5, and the motor outputs different power under different loads, so that the construction elevator can be started smoothly no matter whether it is rising or falling, regardless of the load. stop and run.
