Description
Technical field
The utility model belongs to building hoist technical field more particularly to a kind of efficiency building hoist.
Background technique
Building hoist is commonly used in construction, the vertical transport work of responsible person's goods.It is high-rise with economic development
Build more and more, the effect of building hoist is just particularly important.With the raising of production level, people and to construction
The energy conservation of elevator, efficiency requirements are higher and higher.
What building hoist mechanism generally all configured at present is worm type of reduction gearing and ordinary three-phase synchronous, and is matched
There is frequency converter.There are problems that following 3: 1, worm type of reduction gearing transmission efficiency is lower, only 70-80%, in use not only
Energy waste is big, and calorific value is big, higher to gear reducer lube and cooling requirements.2, ordinary three-phase synchronous is in frequency conversion
Have the shortcomings that weak heat-dissipating, receiving high frequency magnetic field ability is poor, speed adjustable range is narrow when working under power supply environment.3, existing to match frequency converter
Elevator cage decline during, cage potential energy is converted into electric energy by motor.This part electric energy is generally by resistance
Case fever consumption, waste are serious.
Summary of the invention
Place, the utility model provide a kind of efficiency building hoist, will apply in order to overcome the above-mentioned deficiencies of the prior art
Work elevator move downward in potential energy be that electric energy feeds back to power grid, energy conservation and environmental protection, and energy utilization efficiency is high.
To achieve the above objectives, the present invention adopts the following technical solutions: a kind of efficiency building hoist, including hang
Cage, guide rail bracket, driving trolley, retarder, variable-frequency motor and energy feedback frequency converter, the guide rail bracket installation on the base, are hung
Cage and driving trolley are mounted on guide rail bracket and connect, and drive and are carried out between trolley and guide rail bracket by rack and pinion engagement mode
Driving, driving trolley are equipped with variable-frequency motor and retarder, and the output shaft of variable-frequency motor is connect with retarder, is equipped at the top of cage
Energy feedback frequency converter, variable-frequency motor are electrically connected with energy feedback frequency converter.
In the above-mentioned technical solutions, the retarder is the retarder of oblique umbrella tooth or the driving of parallel axes.
In the above-mentioned technical solutions, the pedestal is externally provided with guardrail.
The beneficial effects of the utility model are: being up to using oblique umbrella tooth or the retarder of the driving of parallel axes, transmission efficiency
96%.Temperature rise is low in operational process, low to gear reducer lube and cooling requirements；It is replaced using variable-frequency motor common phase asynchronous
Motor possesses the feature that good heat dissipation, the class of insulation are high, speed adjustable range is big, and than ordinary three-phase synchronous saving energy 10%；
Conventional inverter device is replaced using energy feedback frequency converter, the potential energy during capable of declining cage is electric energy and returns after modulating
It is fed to power grid, the energy can be greatlyd save.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Wherein: 1, guide rail bracket, 2, cage, 3, driving trolley, 4, retarder, 5, variable-frequency motor, 6, energy feedback frequency converter,
7, guardrail, 8, pedestal.
Specific embodiment
With reference to the accompanying drawing and specific embodiment the utility model is described in further detail.
A kind of efficiency building hoist as shown in Figure 1, including cage 2, guide rail bracket 1, driving trolley 3, retarder 4, change
Frequency motor 5 and energy feedback frequency converter 6, the guide rail bracket 1 are mounted on pedestal 8, and cage 2 and driving trolley 3 are mounted on guide rail
It on frame 1 and connects, drives and driven between trolley 3 and 1 frame of guide rail by rack and pinion engagement mode, drive and set on trolley 3
There are variable-frequency motor 5 and retarder 4, the output shaft of variable-frequency motor 5 is connect with retarder 4, and the output shaft and gear of retarder 4 connect
It connects, gear with the rack gear on guide rail bracket 1 by engaging so that the up and down motion of cage is realized, equipped with energy feedback at the top of cage 2
Frequency converter 6, variable-frequency motor 5 are electrically connected with energy feedback frequency converter 6.Variable-frequency motor replaces ordinary three-phase synchronous, possesses scattered
The feature that heat is good, the class of insulation is high, speed adjustable range is big, and than ordinary three-phase synchronous saving energy 10%.It is returned using energy
It presents frequency converter and replaces conventional inverter device, the potential energy during capable of declining cage is electric energy and feeds back to power grid after modulating,
The energy can be greatlyd save.
In the above-mentioned technical solutions, the retarder 4 is the retarder of oblique umbrella tooth or the driving of parallel axes.Transmission efficiency is up to
96%.Temperature rise is low in operational process, low to gear reducer lube and cooling requirements.
In the above-mentioned technical solutions, the pedestal 8 is externally provided with guardrail 7.Guardrail 7 can by cage 2 in lifting process with
Isolation is opened, and someone is in below cage 2 when preventing cage 2 from dropping to bottom.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.
