The U-shaped bending diameter variation testing apparatus comprises a testing chamber with adjustable temperature and a cable hanging rack which can be horizontally moved, wherein the temperature in the testing chamber with adjustable temperature can be controlled and adjusted from -40 DEG C to 60 DEG C, the cable hanging rack is arranged in the testing chamber with adjustable temperature and used for fixing two ends of the traveling cable, and the traveling cable is bent to be in a U shape.
Description
Technical field
The utility model relates to elevator accessory device field, and particularly a kind of super high speed elevator trailing cable U-shaped bending diameter changes test unit.
Background technology
At present, a kind of super high speed elevator trailing cable of flat is arranged on foreign market, please refer to Fig. 1, trailing cable 1 has a U-shaped bending in the elevator lower end.Determine the factor of flat type trailing cable U-shaped bending diameter size, depend on more than 90% that the Shore A hardness desired value of the PVC sheath material that is overlayed on cable outer layer determines.The Shore A hardness value is large, and the PVC material is just hard, makes flat type trailing cable bending diameter also corresponding large.But hard PVC material commonly used has, its fatal defect---resistance to low temperature is poor.Especially in for mobile occasion situation, environment temperature one is low, the trailing cable U-shaped bending diameter that adopts the large material of Shore A hardness value to make sharply increases, and changes the U-shaped bending diameter of flat type cable moving, thereby causes flat type trailing cable insulated wire cores fracture.And when environment temperature is low, the as easy as rolling off a log cracking of cable cover(ing).Chinese Regional is vast, reaches Sanya, Hainan in the south, and environment temperature almost all remains on 30 ℃ throughout the year, and north is to the Heilungkiang Mo River, and winter, extreme low temperature can reach below-40 ℃.Building in the temperature difference greatly different region like this all may lift-mounting.Therefore, the test that the U-shaped bending is carried out under different temperatures is necessary, and the purpose of this utility model is to change test unit in order to provide a kind of for trailing cable U-shaped bending diameter, to make up the vacancy of market, technology.
The utility model content
The utility model is for the prior art above shortcomings, provide a kind of super high speed elevator trailing cable U-shaped bending diameter to change test unit, in order to the trailing cable U-shaped bending carry out the test under different temperatures, guarantee at different temperature, the variation of trailing cable U-shaped bending diameter is within margin tolerance.
The utility model is achieved through the following technical solutions:
A kind of super high speed elevator trailing cable U-shaped bending diameter changes test unit, for the U-shaped bending to a trailing cable, carries out the test under different temperatures, comprising:
One adjustable temperature experimental cabin, the temperature in the adjustable temperature experimental cabin can be controlled adjustment from-40 degrees centigrade～60 degrees centigrade;
One Cable hanger that can move horizontally, be arranged in the adjustable temperature experimental cabin, in order to the fixing two ends of trailing cable, and the trailing cable bending that takes the shape of the letter U.
Preferably, also comprise reference record equipment, in order to automatically to record the U-shaped bending diameter of the trailing cable under different temperatures;
Preferably, adjustable temperature experimental cabin volume is 10 cubic metres, and trailing cable is 5 meters.
The accompanying drawing explanation
Shown in Fig. 1 is the structural representation of elevator trailing cable;
Shown in Fig. 2 is structural representation of the present utility model;
Shown in Fig. 3 is the change rate curve table of trailing cable U-shaped bending diameter under different temperatures that the utility model records.
Embodiment
Below with reference to accompanying drawing of the present utility model; technical scheme in the utility model embodiment is carried out to clear, complete description and discussion; obviously; as described herein is only a part of example of the present utility model; it is not whole examples; embodiment based in the utility model, the every other embodiment that those of ordinary skills obtain under the prerequisite of not making creative work, belong to protection domain of the present utility model.
For the ease of the understanding to the utility model embodiment, take specific embodiment below in conjunction with accompanying drawing and be further explained as example, and each embodiment does not form the restriction to the utility model embodiment.
Please refer to Fig. 2, a kind of super high speed elevator trailing cable U-shaped bending diameter changes test unit, for the U-shaped bending of a trailing cable is carried out to the test under different temperatures, comprise: an adjustable temperature experimental cabin 2, the temperature in the adjustable temperature experimental cabin can be controlled adjustment from-40 degrees centigrade～60 degrees centigrade; One Cable hanger that can move horizontally 3, be arranged in adjustable temperature experimental cabin 2, in order to the fixing two ends of trailing cable 1, and trailing cable 1 bending that takes the shape of the letter U.
Adjustable temperature experimental cabin 2 mention approximately 10 cubic metres.Temperature in adjustable temperature experimental cabin 2 can be controlled adjustment from-40～60 degrees centigrade of scopes.A trailing cable hanger 3 that can move horizontally is set in cabin.
Get 5M trailing cable 1, after the bending of one-tenth U-shaped, two ends are fixed on Cable hanger.Start test from-30 ℃.Heighten each time 5 ℃, all need to record measured value (can adopt manual record or recording unit record, the utility model does not limit at this), the U-shaped bending diameter is adjusted in the cabin of going forward side by side.Until the temperature adjustment rises to 30 ℃, test finishes.According to each measurement result, be made into " the change rate curve table of trailing cable U-shaped bending diameter under different temperatures ", please refer to Fig. 3, top dotted line is the rate of change upper limit curve of trailing cable U-shaped bending diameter under different temperatures, following dotted line is the rate of change lower limit curve of trailing cable U-shaped bending diameter under different temperatures, and middle solid line is the rate of change mean value of trailing cable U-shaped bending diameter under different temperatures.
Can judge that with reference to " the change rate curve table of trailing cable U-shaped bending diameter under different temperatures " trailing cable is in the different temperatures situation, the changing value of its U-shaped bending diameter as fluctuateed all the time in the margin tolerance of regulation, and cable is qualified.As changing value surpasses margin tolerance, cable is defective.
Through repeatedly select adjusting the sheath material formula, manufacture again different cable sample repetition tests after making sheath material, finally research and develop into the special jacket material that function meets " table one " institute column data.
Table one
The listed Shore durometer number A of table one scope is from 84%～96%.Trailing cable in this scope all can, by-25 ℃ of low temperature brittleness tests, meet the cryogenic property index with material.Wherein Shore durometer number 96% is ultimate value, and its corresponding flat type cable U-shaped bending diameter maximum can be accomplished 1000mm.
The above; it is only preferably embodiment of the utility model; but protection domain of the present utility model does not limit to therewith; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
