Description

Technical Field

[0001] The utility model relates to the technical field of rail transit busbar contact network, and more specifically, to a rigid contact line reinforcement device. Background Art

[0002] In rail transit catenary systems, rigid suspension holds a key position due to its unique advantages. By clamping the contact wires to the busbar, the rigid suspension system not only eliminates axial tension and the risk of wire breakage, but also enjoys industry recognition for its simple structure and minimal maintenance effort. However, with the increasing business of rail transit operations, rigid suspension systems are facing a number of challenges. In particular, mechanical wear between the pantograph and the contact wire has become a key factor restricting the system's stable operation.

[0003] During the operation of electric passenger cars, the sliding contact between the pantograph carbon plate and the contact wire is the key to current collection. However, the inelastic nature of the rigid suspension busbar makes it unable to effectively offset the lifting force of the pantograph, resulting in prominent mechanical wear problems. Especially under dynamic conditions such as train acceleration, the wear problem is more serious. This not only affects the service life of the contact network, but also poses a threat to the safe operation of rail transit. At present, for severely worn contact wires, the main method is to replace the entire anchor section, but this method is not only costly and inefficient, but also affects the operating efficiency of the line. Therefore, the development of a safe, convenient and efficient contact wire partial replacement technology has become a technical problem that urgently needs to be solved in the current rail transit field.

[0034] Figure 1 、 Figure 2 、 Figure 3 This is a structural diagram of a rigid contact line reinforcement device according to an embodiment of the present invention, wherein the rigid contact line reinforcement device comprises:

[0036] Specifically, in one embodiment, two reinforced contact lines 7 are provided, and the two reinforced contact lines 7 are equal in length and of the same model. The length of the reinforced contact line 7 is greater than the length of the wear area on the wear contact line 3 .

[0037] The reinforcement module 2 can be made of aluminum alloy material, such as Figure 5 、 Figure 6 As shown, the straight section 22 and the straight portions of the two warped transition sections 21 are respectively the second straight unit and the first straight unit described below.

[0038] In one embodiment, the tilt transition section 21 includes a tilt unit and a first straight unit, and the tilt unit tilts upward from bottom to top relative to the first straight unit.

[0039] In one embodiment, the angle formed by the warp unit of the warp transition section 21 and the busbar 1 is 2° to 5°, and in one example, is 2.67°.

[0040] Specifically, the nose unit of the nose transition section 21 is an angle nose from bottom to top, and the included angle of the nose unit of the nose transition section 21 is 2.67°. The angle nose of the nose unit from bottom to top refers to the direction from the straight part of the nose transition section 21 to the top of the busbar 1 with the bottom plane of the straight part in the nose transition section 21 as the reference plane, in order to avoid abnormal collision between the carbon slide 10 and the reinforced contact line 7, and ensure smooth transition without damaging the carbon slide 10. Figure 10 As shown, the angle at the end of the busbar 1 is also 2.67°, in order to ensure that the carbon slide plate 10 passes smoothly when passing through the intersection of adjacent anchor sections of the rigid contact line.

[0041] In one embodiment, the straight section 22 includes a second straight unit, and two ends of the second straight unit correspond to the first straight unit in the warped head transition section 21 respectively.

[0046] In one embodiment, the gap 6 is provided between the first straight unit or the second straight unit and the clamping block 4 .

[0047] Specifically, the gap 6 is arranged between the straight section 22 or the straight part in the warp transition section 21 and the clamping block 4, that is, the bottom end of the side wall of the straight part in the straight section 22 or the warp transition section 21 is provided with a gap B edge 62, and the bottom end of the side wall of the clamping block 4 is provided with a gap A edge 61.

The reinforced contact line 7 is placed in the gap 6, and the height value between the two reinforced contact lines 7 and the top of the bus 1 is greater than the height value between the wear contact line 33 and the top of the bus 1.

[0048] In one embodiment, bolts are provided between the connecting block 5 and the clamping block 4 .

[0049] In one embodiment, the clamping block 4 , the straight section 22 and the two tilted transition sections 21 are all provided with hollow holes 9 .

[0050] Specifically, hollow holes 9 are provided on the clamping block 4 , the straight section 22 and the two tilted transition sections 21 , in order to meet the requirements of ease of use such as simplicity, lightness, easy installation and replacement.

[0051] In one embodiment, the length of the reinforcement module 2 may be 50 cm, and the weight of a single component does not exceed 700 g.

[0052] The rigid contact line reinforcement device meets the universal structural installation requirements of different types of rigid suspension contact network busbars 1 when in use, and the reinforcement device must meet the matching requirements of electrical and mechanical performance when connected to the existing busbar 1 when in use;

[0053] When in use, the reinforcement device meets the reinforcement requirements within the range of abnormal wear length of different rigid suspension contact lines, and is compatible with the structural installation forms of different rigid suspension points;

[0054] When using this reinforcement device, it is necessary to focus on the compatibility with the subway pantograph, so as to meet the smooth transition requirements when the pantograph passes through abnormally severe wear locations such as rigid suspension exit and accelerated current section.

[0055] When in use, the reinforcement device should comply with the insulation limits of the contact network equipment: 115mm for live metal to ground wire; 100mm for live metal to cement components.

[0057] Figure 11 This is a flowchart of a rigid contact line reinforcement method according to an embodiment of the present invention, comprising:

[0058] Step S101, testing the contact line on the test busbar to confirm the wear area of the worn contact line on the busbar;

[0059] Step S102, installing reinforcement modules on both sides of the busbar;

[0060] Step S103, using a reinforcement module to fix reinforced contact lines on both sides of the busbar in a mirrored manner, and then adjusting the reinforced contact lines so that the reinforced contact lines are parallel to the worn contact lines;

[0061] Figure 12 This is a flow chart illustrating the implementation of the carbon slide in the present invention, which sequentially contacts the worn contact line, the reinforced contact line, and the worn contact line. As the train moves, the top of the carbon slide slides from an unworn position on the worn contact line to the reinforced contact line and then back to an unworn position on the worn contact line, avoiding the worn area of the worn contact line.

[0062] Preferably, there are two reinforced contact lines, which are placed on both sides of the wear contact line.

[0063] Preferably, the height between the two reinforced contact lines and the top of the busbar is greater than the height between the worn contact line and the top of the busbar, and the ends of the two reinforced contact lines cooperate with the carbon slide plate.

[0064] When performing maintenance work, confirm the wear area of the wear contact line 3 on the bus 1, and use the above-mentioned reinforcement module 2 to install two reinforced contact lines 7 on both sides of the bus 1 in a mirrored manner. The two reinforced contact lines 7 are parallel to the wear contact line 3, and the wear area on the wear contact line 3 is located between the two reinforced contact lines 7. The height value between the two reinforced contact lines 7 and the top of the bus 1 is greater than the height value between the wear contact line 3 and the top of the bus 1. The ends of the two reinforced contact lines 7 are jointly matched with the carbon slide plate 10 of aluminum alloy material, so that the top of the carbon slide plate 10 slides from the wear contact line 3 to the reinforced contact line 7 and then to the wear contact line 3 to avoid the wear area of the wear contact line 3.

[0065] Preferably, the ends of the reinforced contact line are arranged to be raised from bottom to top, the middle portion is a smooth portion, and the raised ends at both ends are mirror-imaged relative to the center line of the reinforced contact line.

[0066] Preferably, the end of the carbon slide passes through the end warping at one end of the reinforced contact line, the smooth portion, and the end warping at the other end in sequence to achieve contact between the carbon slide and the reinforced contact line.

[0067] Preferably, the distance between the carbon slide plate and the reinforcement contact line is smaller than the distance between the carbon slide plate and the wear contact line.

[0068] Preferably, the carbon slide plate is lifted and lowered by a lifting unit.

[0069] Preferably, when installing the reinforcement module, it is necessary to ensure that both the front and rear ends of the reinforcement contact line are beyond the abnormal wear zone.

[0070] Preferably, the reinforced contact lines are of equal length and the same type, so that the worn contact lines are suspended.

[0071] Preferably, the carbon slide plate is made of aluminum alloy.

[0072] The end of each reinforced contact line 7 is set to be raised from bottom to top, and the raised ends are mirror-imaged relative to the center line of the reinforced contact line 7. The end of the carbon slide 10 is sequentially passed through the raised end, the smooth part, and the raised end of the other end of the reinforced contact line 7 to achieve contact between the carbon slide 10 and the reinforced contact line 7. It should be noted that due to the different shapes of raised and smooth shapes on the reinforced contact line 7 and the distance between the raised end and the wear contact line 3, the carbon slide 10 adopts a lifting mechanism to achieve its lifting.

[0073] The length of the reinforced contact line must be greater than the length of the wear area on the wear contact line 3. In addition, when installing the above-mentioned reinforcement module 2, it is necessary to ensure that the front and rear ends of the reinforced contact line 7 on the reinforcement module 2 are beyond the abnormal wear area.

[0074] The present application mainly aims to install two new contact lines of equal length and the same model on the left and right sides of the contact line that has undergone abnormal wear, namely the worn contact line 3 section, in a mirrored manner, namely the reinforced contact line 7, so as to suspend the worn contact line 3, that is, the distance between the carbon slide plate 10 and the reinforced contact line 7 is smaller than the distance between the carbon slide plate 10 and the worn contact line 3; so that the carbon slide plate 10 no longer continues to have sliding friction with the worn contact line 3 in this section, but instead simultaneously has sliding friction with the reinforced contact line 7, ultimately achieving the function and effect of enhancing the service life of the local contact line in this section.

[0075] The utility model has the following beneficial effects:

[0076] 1. Easy to operate: When in use, the reinforcement device meets the reinforcement requirements within the abnormal wear length range of different rigid suspension contact lines, and is compatible with the structural installation forms of different rigid suspension points.

[0077] 2. Versatility: The rigid contact line reinforcement device has multiple hollow holes, which can meet the universal structural installation requirements of different types of rigid suspended contact network buses when used.
