Above-mentioned mounting part is provided with the hole, and set bolt passes the hole of fixture, and fixture is fixed on the long stator iron core.
Above-mentioned design failure position is positioned at the edge of the mounting seat plate of long stator iron core, perhaps is arranged near the bottom of fixture or its.
Above-mentioned design failure position utilizes bending process to form, and perhaps forms by being designed to the smallest cross-sectional position, perhaps is designed to stress and concentrates the position to form.
Above-mentioned cable position point is the hook-shaped of opening or the annular of sealing.
The internal diameter of above-mentioned cable position point is greater than the external diameter of cable.
Above-mentioned fixture adopts the nonferromagnetic insulating material.
The utility model long-stator linear motor cable fixture is compared with existing cable fixture, and its advantage is that the utility model adopts nonferromugnetic material, and the influence of having stopped high-intensity magnetic field has corrosion resistance, long service life;
The utility model is provided with the design failure position, and guaranteeing can not influence system safety operation after the component failure, improves the stability of a system;
The utility model is simple in structure, and simple installation is saved cost.

Fig. 2 is the structural representation of the closed ring of a kind of long-stator linear motor cable of the utility model fixture;
Fig. 3 is the structural representation of a kind of long-stator linear motor cable of the utility model fixture.
Embodiment
Specify embodiment of the present utility model below in conjunction with accompanying drawing.
See also shown in Figure 1ly, a kind of long-stator linear motor cable of the utility model fixture 1 comprises the mounting part 13 on top, the design failure position 11 at middle part and the cable position point 12 of bottom; Described mounting part 13 is installed on the set bolt 3 of long stator iron core 4, utilizes set bolt 3 fixing, and this design failure position 11 utilizes bending process to form.
The nonferromugnetic material that adopts in the utility model fixture 1 is the strip stainless steel, and material is cheap; Overpunch at fixture 1, the diameter of the set bolt 3 of the diameter in this hole and long stator iron core 4 is suitable, for reducing influence to environment for use magnetic field, can also adopt macromolecular material such as nylon for example, hard nonferromagnetic and non-conducting material manufacturing, the hole on fixture 1 top is installed on the set bolt 3 of long stator iron core 4, utilizes fixed by nut in set bolt 3.
The middle part of fixture 1 is in the edge of the mounting seat plate of long stator iron core 4, fixture 1 is in this position bending, fixture 1 stretches among two seams between the long stator iron core 4, this bending process has caused the inhomogeneous sudden change of material behavior, weak spot on the intensity of Xing Chenging has formed design failure position 11 naturally herein, the requirement of maximum service life (MSL) need be satisfied in this design failure position 11, this position is uniquely in the fixture 1 to allow to occur the structural destruction position, its theoretical strength is a little less than other any position of fixture 1, purpose is to make fixture 1 in use just in case be damaged, then at first occur in this position, and because fixture 1 destroys in this position, the consequence that causes not answering system operation has any influence.Design failure position 11 also can become the smallest cross-sectional position to form by the Cross-section Design with fixture 1 this position; Or also can concentrate the position to form by fixture 1 this position being designed to stress.According to the shape of fixture 1 and the difference of material, except design failure position 11 being arranged on the middle part of fixture, also design failure position 11 can be arranged on other position of fixture 1, for example can be located at the bottom or near, fixture 1 should lose the effect of contraction to stator cable 2 when need to guarantee lost efficacy taking place, and can not retrained by the shape of stator cable 2 and cause and can't come off or stator cable 2 is left behind; Simultaneously, difference according to shape, material and the processing method of fixture 1, different manufacture methods can be adopted in design failure position 11, for example can be to utilize fixture 1 adding the local damage that stays man-hour, also can be just deliberately to form stress during in design outline to concentrate that for example minimum cross section forms design failure position 11.
The bottom bending of fixture 1 constitutes cable position point 12, this cable position point 12 is set to the hook-shaped of opening, its internal diameter is more bigger than the external diameter of unsettled stator cable 2, can hold cable under the normal condition, design guarantees that normal life cycle internal fixation spare 1 can not destroy, in the time can not meeting the demands under the cost of the strength of materials that adopts in economy, except the planform of non-closed hook, as shown in Figure 2, can also be designed to close-shaped non-open-type to increase the intensity of fixture.
As shown in Figure 3, each has a pair of fixture 1 of the present utility model of the parallel installation in position of unsettled stator cable 2 on the long stator iron core 4, if run into improper load action, the load that fixture 1 is subjected to is region of stress concentration of 11 formation at the design failure position, and contingent structural deterioration will occur on the inflection point, middle part of fixture 1.Thereby when fixture 1 lost efficacy generation, fixture 1 at first ruptured in this position.Fixture 1 is after design failure position fracture, and its top still is fixed on original position by set bolt 3, and the bottom then because action of gravity comes off voluntarily, breaks away from whole system and falls.At this moment, cable relies on another adjacent fixture 1, and the structural strength of itself still can remain on the original place change failed fixture 1 when maintenance test.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute all will be conspicuous.Therefore, protection range of the present utility model should be limited to the appended claims.
