Description
Technical Field
[0001] The invention belongs to the field of electromagnet testing, and in particular relates to an electromagnet testing installation fixture and an installation structure. Background Art
[0002] At present, the maximum speed of domestic medium and low-speed maglev trains is 140km / h. Changes in factors such as vehicle speed and line conditions will significantly change the demand for the suspension guiding force of the electromagnet. Therefore, it is crucial to test the electromagnetic performance of the suspension electromagnet in research, design, production and testing.
[0003] At present, the electromagnetic performance testing equipment of the suspended electromagnet generally fixes the electromagnet directly on the test frame, which makes it inconvenient to adjust the position and gap of the electromagnet relative to the track. In addition, at present, an electromagnet testing device is generally limited to one testing method, such as an electromagnet static testing device and an electromagnet dynamic testing device. It is difficult to obtain performance tests of the electromagnet in different environments and working conditions on one testing device. Summary of the invention
[0004] The technical problem to be solved by the present invention is to provide an electromagnet test installation fixture and an installation structure which can simply and effectively switch the test working conditions.
[0005] The present invention provides an electromagnet test installation fixture, comprising a frame and a longitudinal gap adjustment member, wherein a group of two mutually parallel limit plates II are respectively arranged at both ends of the frame along the longitudinal direction, and the frame is arranged on a test frame connecting plate along the longitudinal direction through the space between the two groups of limit plates II, and the longitudinal gap adjustment member is a linear moving member II arranged on the two limit plates II and facing the test frame connecting plate.
[0006] Furthermore, a guide column is arranged between the two limit plates II, a guide hole cooperating with the guide column is arranged on the test frame connecting plate, and the guide column is arranged parallel to the linear moving part II.
[0007] Furthermore, two linear moving parts II are laterally arranged on the upper edge of the limit plate II close to the electromagnet.
[0008] The electromagnet test installation fixture also includes an electromagnet installation frame slidably arranged on the frame body and a transverse gap adjustment member for adjusting the position of the electromagnet installation frame within the sliding stroke.
[0009] Furthermore, the electromagnet mounting frame includes two sets of L-shaped mounting plates arranged opposite to each other, the electromagnet is mounted between the two L-shaped mounting plates, and the other side of the L-shaped mounting plate is slidably connected to the frame body.
[0010] Furthermore, the frame body is provided with a strip groove, and the L-shaped mounting plate is provided with a bolt that matches the strip groove.
[0011] Furthermore, the lateral gap adjustment member includes a limit plate I arranged on both sides of the frame body in the sliding direction of the electromagnet mounting frame and a linear moving member I arranged on the limit plate I toward the direction of the electromagnet mounting frame.
[0012] Furthermore, the linear moving parts I and II are cylinders, hydraulic cylinders or screws screwed on the limit plates I and II.
[0013] Furthermore, the frame is provided with limit blocks on both sides of the two L-shaped mounting plates.
[0014] The present invention also provides an electromagnet test installation structure, including a test frame and an electromagnet test installation fixture, wherein two test frame connecting plates are relatively arranged on the test frame, and the electromagnet test installation fixture is arranged on the test frame connecting plate through two relatively arranged limit plates II on both sides of its frame.
[0015] The beneficial effect of the present invention is that the present invention uses the frame for installing the electromagnet to be clamped on the test frame connecting plate by two limit plates II, and can provide two test modes for the electromagnet in combination with the longitudinal gap adjustment member: one test mode is a dynamic test mode, and two sets of linear moving parts II limit the upper and lower movement limit travel of the electromagnet test installation fixture and the electromagnet relative to the test frame. At this time, the electromagnet can be dynamically tested for suspension force and guiding force, and the movement travel of the electromagnet is limited, simulating the working state from hovering to suspension when the suspension train starts, and then realizing the suspension force and guiding force data collection in the process of hovering to suspension, providing more scenes for the performance of the electromagnet. The other test mode is a static test mode, that is, the upper and lower linear moving parts II are both in contact with the test frame connecting plate, directly locking the position of the electromagnet test installation fixture relative to the test frame, and at this time, the upper and lower linear moving parts II are adjusted at the same time, and the gap between the electromagnet and the track on the electromagnet test installation fixture can be adjusted, and the adjustment is convenient and quick, realizing the suspension force and guiding force test of the electromagnet under static state.
[0016] The longitudinal gap adjustment part has a simple and reliable structure, and it is extremely convenient and quick to switch between the static test mode and the dynamic test mode. The static test mode can effectively ensure that the position of the electromagnet is fixed, while the upper and lower limit moving positions of the electromagnet can be easily adjusted in the dynamic test mode, so that the electromagnet performance test under the simulated train condition is closer to the real hovering condition.

[0030] As attached Figure 1-7 As shown, the electromagnet test mounting fixture 4 is used to install the electromagnet 3, and the electromagnet test mounting fixture 4 is set on the test frame 1. The test frame 1 is also provided with a track 2 corresponding to the electromagnet 3, which is used to test the guiding force and / or suspension force of the electromagnet 3 in combination with the suspension force test component and / or the guide force test component.
[0031] The electromagnet test installation fixture 4 includes a frame 41 and a longitudinal gap adjustment member 44. A group of two mutually parallel limit plates Ⅱ411 are respectively arranged at both ends of the frame 41 along the longitudinal direction. The frame 41 is arranged on the test frame connecting plate 11 along the longitudinal direction through the space between the two groups of limit plates Ⅱ411. The longitudinal gap adjustment member 44 is a linear moving member Ⅱ441 arranged on the two limit plates Ⅱ411 and facing the test frame connecting plate 11.
[0032] As attached Figure 3 and attached Figure 4 As shown in the present invention, the frame 41 for mounting the electromagnet 3 is clamped on the test frame connecting plate 11 by two limit plates II 411, and combined with the longitudinal gap adjustment member 44, two test modes of the electromagnet 3 can be provided:
[0033] One of the test modes is a dynamic test mode, that is, after adjustment, the end width of the two groups of linear moving parts Ⅱ441 is greater than the thickness of the test frame connecting plate 11, and the two groups of linear moving parts Ⅱ441 limit the upper and lower movement limit strokes of the electromagnet test mounting fixture 4 and the electromagnet 3 relative to the test frame 1. The lower linear moving part Ⅱ441 can adjust the maximum shortest distance between the electromagnet test mounting fixture 4 and the track 2, and the upper linear moving part Ⅱ441 can adjust the initial distance of the electromagnet test mounting fixture 4, which is also the maximum longest distance between the electromagnet test mounting fixture 4 and the track 2. At this time, the electromagnet 3 can be dynamically tested for suspension force and guiding force, and the moving stroke of the electromagnet 3 can be limited to simulate the working state from hovering to suspension when the suspended train starts, thereby realizing the suspension force and guiding force data collection in the process from hovering to suspension, providing more scenarios for data collection for the performance of the electromagnet 3.
[0034] Another test mode is a static test mode, that is, after adjustment, the end widths of the two groups of linear moving parts Ⅱ441 are equal to the thickness of the test frame connecting plate 11, that is, the upper and lower linear moving parts Ⅱ441 are both in contact with the test frame connecting plate 11, and the position of the electromagnet test mounting fixture 4 relative to the test frame 1 can be directly locked. At this time, by adjusting the upper and lower linear moving parts Ⅱ441 at the same time, the gap between the electromagnet 3 and the track 2 on the electromagnet test mounting fixture 4 can be adjusted, and the adjustment is convenient and quick, thereby realizing the suspension force and guide force test of the electromagnet 3 under static conditions.
[0035] The longitudinal gap adjustment member 44 has a simple and reliable structure, and it is extremely convenient and quick to switch between the static test mode and the dynamic test mode. In the static test mode, the position of the electromagnet 3 can be effectively guaranteed to be fixed, while in the dynamic test mode, the upper and lower limit moving positions of the electromagnet 3 can be easily adjusted, and the simulation train is closer to the electromagnet performance test in a real hovering state.
[0036] A guide post 412 is also provided between the two limit plates II 411, and a guide hole 111 cooperating with the guide post 412 is provided on the test frame connecting plate 11, and the guide post 412 is provided in parallel with the linear moving member II 441. In this embodiment, by providing the guide post 412 on the frame body 41 and the guide hole 111 on the test frame connecting plate 11, the electromagnet test installation fixture 4 has a guiding function during the up and down movement or adjustment process, and will not be excessively displaced in a large range of the front, back, left and right directions, thereby simplifying the difficulty of position adjustment of the electromagnet test installation fixture 4. At the same time, in the dynamic test mode, it is ensured that the electromagnet test installation fixture 4 can only move in a linear suspension manner without deviation to the left and right.
[0037] Two linear moving parts II441 are laterally arranged on the upper edge of the limit plate II411 close to the side of the electromagnet 3. In this embodiment, by arranging two linear moving parts II441 on the upper side, the limiting stability of the linear moving part II441 on the test frame connecting plate 11 can be improved in the static mode, thereby ensuring the position stability of the electromagnet test mounting fixture 4 and the horizontal stability of the electromagnet test mounting fixture 4 in the initial state in the dynamic mode.
[0038] In one of the embodiments, the electromagnet test mounting fixture 4 also includes an electromagnet mounting frame 42 slidably set on the frame body 41 and a lateral gap adjustment member 43 for adjusting the position of the electromagnet mounting frame 42 within the sliding stroke, which can be used to adjust the position of the electromagnet 3 relative to the track 2, facilitate the position adjustment of the electromagnet 3, and provide electromagnet 3 performance tests under various working conditions.
[0039] The electromagnet mounting frame 42 includes two sets of L-shaped mounting plates arranged opposite to each other, and the two L-shaped mounting plates are used to install the electromagnet 3. The other side of the L-shaped mounting plate is slidably connected to the frame body 41, and the transverse gap adjustment member 43 is directly installed on the frame body 41. The transverse gap adjustment member 43 includes a limit plate Ⅰ431 arranged on both sides of the frame body 41 in the sliding direction of the electromagnet mounting frame 42 and a linear moving member Ⅰ432 arranged on the limit plate Ⅰ431 in the direction of the electromagnet mounting frame 42. The linear moving member Ⅰ432 directly contacts the electromagnet mounting frame 42, pushes and limits the movement of the electromagnet mounting frame 42, and then adjusts the transverse position of the electromagnet 3. It can adapt to the installation and adjustment of electromagnets 3 of different widths and sizes, and has a simple structure and convenient and quick operation. Specifically, a strip groove 413 is arranged on the frame body 41, and a bolt matching the strip groove 413 is arranged on the L-shaped mounting plate.
[0040] The linear moving part I432 and the linear moving part II441 are cylinders, hydraulic cylinders or screws screwed on the limit plate I431 and the limit plate II411. Preferably, the linear moving part I432 and the linear moving part II441 are screwed on the screws and have a self-locking function. The position can be fixed directly by self-locking after adjustment, and the structure is simple and reliable, the operation is convenient, and the cost is low.
[0041] The frame 41 is provided with limit blocks 414 on both sides of the two L-shaped mounting plates. By providing the limit blocks 414, when the electromagnet 3 is adjusted in the lateral direction, there will be no deviation in another direction, thus simplifying the adjustment difficulty.
[0042] The present invention also provides an electromagnet test installation structure, including a test frame 1 and an electromagnet test installation fixture 4, wherein two test frame connecting plates 11 are relatively arranged on the test frame 1, and the electromagnet test installation fixture 4 is arranged on the test frame connecting plate 11 through two relatively arranged limit plates II 411 on both sides of its frame body 41.
[0043] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
