The refrigeration device is characterized in that the compressed air source output pipe orifice of the air compressor (2) is respectively connected with a plurality of vortex tubes (3) which are taken as cooling modules through pipelines, and the cool air output pipe orifice of each vortex tube (3) leads to a corresponding encoder (4). Compared with the prior art, the vortex tube refrigeration system adopted by the utility model not only has the advantages of good refrigeration effect, fast speed, no pollution, simple structure and small volume, but also has no mechanical damage to the cooling modules, no electric power wastage, simple and reliable control as well as fluorine-free coolant realization due to the fact that the refrigeration device takes the self-equipped engine as the power source, takes the air compressor as the air source, and takes the vortex tubes as the cooling modules.
Description
Technical field
The utility model relates to a kind of Refrigeration Technique, particularly a kind of refrigerating plant that is applicable to the cooling of the encoder on the multi-mode steering mobile device.This refrigerating plant is applicable to the refrigerating plant as the cooling of the encoder on the rubber-tyred mobile device of the multi-mode steering in shipyard, steel mill, harbour, engineering machinery, petrochemical industry and the high-speed railway transportation rack device.
Background technology
In using rubber-tyred migration moving being equipped with of multi-mode steering, various needs need to use a kind of bus-type rotary encoder, and this bus-type rotary encoder great majority all can not adapt to the adverse circumstances under the hot environment, the unexpected out-of-work phenomenon of rotary encoder often appears, make equipment impaired, this phenomenon is particularly serious on the molten steel hired car of steel mill especially.
For improving the working environment of encoder, the general following technique measures that adopt of prior art are lowered the temperature to encoder more, as: semiconductor refrigerating or cooling water circulation system.Semiconductor chilling plate has good refrigeration effect, fireballing advantage, but structure relative complex, and reliability is low.And that the cooling water circulation system has is simple in structure, advantage such as pollution-free, but volume is huge relatively.
Summary of the invention
The purpose of this utility model also is in order to improve the working environment of rotary encoder, reduce its environment temperature and provide a kind of structure more reasonable, have good refrigeration effect, speed is fast, pollution-free, simple in structure, volume is little is applicable to refrigerating plant for the cooling of the encoder on the multi-mode steering mobile device.
The purpose of this utility model can realize by following technical measures:
The refrigerating plant of lowering the temperature for the encoder on the multi-mode steering mobile device that is applicable to of the present utility model is included as the engine that turns to mobile device that power is provided, by the air compressor of engine as power source, the compressed gas source output mouth of pipe of described air compressor links to each other with some vortex tubes as cooling module respectively by pipeline, and the cold air output mouth of pipe correspondence of each vortex tube is led to an encoder installed position.
The capacity of air compressor described in the utility model is selected can be selected according to the required capacity of vortex tube.
Principle of the present utility model is to utilize the engine that carries on the mobile device to drive air compressor, and provide the refrigeration source of the gas for vortex tube by air compressor, utilize the cold air of vortex tube output to provide a low temperature environment, thereby guarantee that encoder can operate as normal to encoder.
The utility model adopts the swirl control cooling system not only to have good refrigeration effect, speed is fast, pollution-free, simple in structure, volume is little characteristics compared to existing technology, also the engine of providing for oneself with equipment because of the utility model is power source, is source of the gas with the air compressor machine, is cooling module with the vortex tube, cooling module itself does not have machinery wearing and tearing, unregulated power loss, and control simple dependable performance, realized floride-free refrigeration.

The specific embodiment
The utility model is further described below with reference to embodiment (accompanying drawing):
In the multi-mode steering mobile device of prior art, engine 1 is absolutely necessary, and the utility model makes full use of this power, configuration air compressor 2, give vortex tube 3 air feed with air compressor, make the cold air end of vortex tube supply with some encoders 4 refrigeration respectively.More specifically say (as shown in Figure 1, 2, 3), the refrigerating plant of lowering the temperature for the encoder on the multi-mode steering mobile device that is applicable to of the present utility model is included as the engine 1 that turns to mobile device that power is provided, by the air compressor 2 of engine as power source, the compressed gas source output mouth of pipe of described air compressor 2 links to each other with some vortex tubes 3 as cooling module respectively by pipeline, and the cold air output mouth of pipe correspondence of each vortex tube 3 is led to encoder 4 installed positions.The structure of vortex tube described in the utility model 3 and operation principle are referring to shown in Figure 4.Owing to all be that the compressed air that adopts compressor to provide is braked in most multi-mode steering mobile device, every engine can be installed two air compressors, so, adopted a compressor to give brake pressure container air feed in the utility model, another compressor is given the mode of vortex tube air feed.When multi-mode steering mobile device axis more, under the also more situation of corresponding encoder, the more vortex tube of needs may occur and give the encoder air feed, the not enough situation of air compressor tolerance at this moment can occur, solution can adopt following two kinds: increase air compressor tolerance 1.; 2. replace air supply method.Generally can adopt method 1.But, when increase air compressor tolerance still can not satisfy, then need adopt alternately air supply method.So-called alternately air supply method be give brake pressure container air feed air compressor under the situation that guarantees the brake pressure container pressure, alternately be the vortex tube air feed, be reached for the purpose of encoder refrigeration.
The operation principle of swirl control cooling system is (referring to Fig. 4): rotate at a high speed in vortex tube with the compressed air of 5-7 kilogram and carry out cold and hot exchange at the inlet end of vortex tube, form hot and cold two strands of air-flows, thermal current is discharged from an end with high slightly pressure by vortex tube, temperature can reach 110 ℃, and can carry out adjustment.Cold airflow is discharged from the other end, and cold airflow can reach-45 ℃ extremely low temperature.
