Description

Technical Field

[0001] The utility model relates to the technical field of switch machine installation, and particularly relates to a line marker for the installation of an electro-hydraulic switch machine. Background Art

[0002] The electro-hydraulic switch machine is an advanced turnout operation device in the railway system. It combines electric and hydraulic technologies and is used to efficiently and safely control the switching of railway turnouts to guide trains from one track to another. Its main function is to enable trains to pass through the turnout smoothly and safely, thereby realizing the switching of tracks and the adjustment of train running routes.

[0003] Currently, in signal engineering, as Figure 1 shown, there are two track mounting holes 601 for fixing the external locking device on the track 6. When installing the electro-hydraulic switch machine, the midline of the external locking device is generally determined by taking the midpoint of the rail top surface and the rail web for marking, that is, the midline 10 of the two track mounting holes 601 is determined. Then, the installation position of the L-shaped iron is determined through the midline 10 of the mounting hole, and the marking for drilling holes in the rail web is completed by using the L-shaped iron. The specific construction method is that after the track professional finishes the fine adjustment and handover of the turnout, according to the installation requirements of the installation atlas of the single-opening turnout conversion equipment (ZYJ7) of the integral ballast bed rail, the position of the midline of the external locking device of the electro-hydraulic switch machine is determined. The construction personnel take the midline of the external locking device as the basis to mark the midline position of the long angle iron of the electro-hydraulic switch machine, and then complete the marking for drilling holes in the rail web by using the L-shaped iron. However, the existing tools for measuring the midline of the external locking device are cumbersome to operate and have different measurement accuracies, seriously affecting the installation efficiency of the switch machine and greatly increasing the labor cost of installing the electro-hydraulic switch machine.

Further, when scribing the center line on the track 6, first abut the first suspension portion 11 against the top surface of the track 6 and install the first positioning tube 13 into the left - hand track mounting hole 601. At this time, scribe a line along the first scribing side edge 100 of the first scribing portion 12, and the scribed line is the center line 10 between the two track mounting holes 601. As Figure 6 、 Figure 7 , then abut the second suspension portion 21 against the top surface of the track 6 and install the second positioning tube 23 into the right - hand track mounting hole 601, and scribe a line again through the second scribing side edge 200 of the second scribing portion 22 to judge whether the center lines 10 scribed on both sides coincide. As Figure 8, so as to inspect the center line 10 and achieve accuracy review. The line marker of the present application draws the center line 10 through the first positioning member 1 and conducts a review through the second positioning member 2, realizing secondary measurement and improving the accuracy of line drawing. At the same time, the first positioning member 1 and the second positioning member 2 have simple structures and convenient positioning, and can achieve rapid line drawing and review.

[0051] In this embodiment, it can also be detected through the second marking side 200 of the second marking part 22 to determine whether the drawn center line 10 coincides with the second marking side 200, so as to inspect the center line 10 and achieve accuracy review.

[0052] In one or several embodiments, as Figure 2 shown, where Figure 2 a is the left side view of the first positioning member 1, Figure 2 b is the front view of the first positioning member 1;

[0053] The first suspension part 11 includes a first top plate 110 and a first side plate 120 connected to each other. The first top plate 110 is used to abut against the top surface of the track 6, and one end of the first side plate 120 away from the first top plate 110 is connected to the first marking part 12. Among them, the first side plate 120 is vertically arranged, and the first side plate 120 is connected to one end of the first top plate 110 away from the track 6.

[0055] In an alternative embodiment, as Figure 2 shown, there is an included angle θ1 between the first top plate 110 and the horizontal plane, and the value range of θ1 is 4° to 6°. As Figure 5As shown in the figure, by setting the included angle θ1, after the first top plate 110 abuts against the top surface of the track 6, during the process of placing the first positioning tube 13 into the track mounting hole 601, the first top plate 110 is squeezed by the top surface of the track 6 and will displace upward, thereby generating a downward reaction force on the first top plate 110, and further enabling the first top plate 110 to tightly press the top surface of the track 6, making the first positioning member 1 more firmly fixed on the track 6.

[0056] In an alternative embodiment, as Figure 2 shown, a first buffer pad 14 is further provided on the side of the first scribing plate 140 close to the track 6. Since the web of the rail is uneven, it is easy to cause a gap between the first scribing plate 140 and the web of the rail, and the gap easily affects the scribing accuracy of the first scribing plate 140. The above-mentioned gap is filled by the first buffer pad 14.

One end of the second horizontal plate 230 is connected to the second side plate 220, and the end of the second horizontal plate 230 away from the second side plate 220 is connected to the second scribing plate 240. A second positioning tube 23 is provided on the second scribing plate 240. The side of the second scribing plate 240 away from the second positioning tube 23 is the second scribing side 200. Among them, the second scribing plate 240 is vertically arranged, and the second horizontal plate 230 and the second scribing plate 240 form a bent structure, making the second scribing plate 240 face away from the second side plate 220. After the second top plate 210 abuts against the top surface of the track 6, it is convenient for the second scribing plate 240 to contact the web of the track 6.

[0061] In an alternative embodiment, asFigure 3 As shown, there is an included angle θ2 between the second top plate 210 and the horizontal plane, and the value range of θ2 is 4° to 6°. By setting the included angle θ2, after the second top plate 210 abuts against the top surface of the track 6, during the process of placing the second positioning tube 23 into the track mounting hole 601, the second top plate 210 is squeezed by the top surface of the track 6 and will displace upward, thereby generating a downward reaction force on the second top plate 210, so that the second top plate 210 can tightly press the top surface of the track 6 and make the second positioning member 2 more firmly fixed on the track 6.

[0062] In an alternative embodiment, as Figure 3 shown, a second buffer pad 24 is further provided on one side of the second scribing plate 240 close to the track 6. Since the web of the rail is uneven, it is easy to cause a gap between the second scribing plate 240 and the web of the rail, and the gap easily affects the scribing accuracy of the second scribing plate 240. The second buffer pad 24 is used to fill the above-mentioned gap.

[0063] In an alternative embodiment, the second top plate 210, the second side plate 220, the second horizontal plate 230 and the second scribing plate 240 are integrally provided. Among them, the second top plate 210, the second side plate 220, the second horizontal plate 230 and the second scribing plate 240 are formed by multiple bends of a steel plate, and the thickness of the steel plate is 2 mm.

Then, the long angle steel 7 is connected to the straight stock rail 61. Through the first positioning member 1 and the second positioning member 2 of this embodiment, the center line 10 of the track mounting hole 601 can be quickly and accurately drawn, so as to facilitate the quick installation of the external locking device 8, and the angle steel positioning line 20 of the long angle steel 7 on the track 6 can be determined through the center line 10. Then, the long angle steel positioning hole 602 is drilled on the track 6 through the angle steel positioning line 20 for installing the long angle steel 7.

[0066] Embodiment 2

[0067] On the basis of Embodiment 1, as Figure 3 、 Figures 9 - 12 shown, a scribing device for installing an electro-hydraulic switch machine described in this embodiment further includes an angle steel positioning member 3.

[0070] In this embodiment, as Figure 9 shown, after determining the center line 10 through the first positioning member 1 and the second positioning member 2, place the angle steel positioning member 3 on the track 6, and then move the angle steel positioning member 3 so that the distance L4 between the third scribing side edge 300 and the center line 10 meets the installation specification requirements of the long angle steel, and then scribe a line on the third scribing side edge 300, that is, draw the angle steel positioning line 20.

Among them, the through-hole indicating line 52 is a vertical line drawn on the surface of the L-shaped iron 5, and the through-hole indicating line 52 passes through the center of the through-hole 51. When placing the L-shaped iron 5 on the track 6, when observing from the through-hole 51 that the angle steel positioning line 20 coincides with the through-hole indicating line 52, holes can be drilled on the track 6 along the through-hole 51.

[0072] As Figures 6 - 12 shown, first through the first positioning member 1 and the second positioning member 2, the center line 10 of the track installation hole 601 can be quickly and accurately drawn, and then use the angle steel positioning member 3 of this embodiment to quickly draw the angle steel positioning line 20 according to the center line 10, and then cooperate with the L-shaped iron 5 to drill the long angle steel positioning holes 602 on the track 6.

[0073] Embodiment 3

[0074] On the basis of Embodiment 2, as Figures 6 - 14As shown in the figure, this embodiment discloses a method for using a line marker for the installation of an electro - hydraulic switch machine, including the following steps:

[0075] Step 1: According to the parameters of the 60 kgm track 6, process a set of line markers for the installation of an electro - hydraulic switch machine, such as Figures 2 - 4 ;

[0076] Step 2: As shown in Figure 5 、 Figure 6 After the first positioning tube 13 of the first positioning member 1 is inserted into the track mounting hole 601 according to the two track mounting holes 601 reserved on the track 6, press the first positioning member 1 horizontally onto the track 6. After the first top plate 110 is in close contact with the rail top surface and the first marking plate 140 is in close contact with the rail web, place a level on the first top plate 110 and observe the level on the first top plate 110. After determining the level, use a fine marker to draw a line along the first marking side 100 of the first marking plate 140, and mark the center line 10 of the external locking device 8 on the track 6;

[0077] Step 3: As shown in Figure 7 、 Figure 8 According to the marked center line 10, use the second positioning member 2 in the same process as in Step 2. If the two center lines 10 coincide, the position of the center line 10 is accurately re - checked;

[0078] Step 4: As shown in Figures 9 - 11 According to the re - checked center line 10, use the angle steel positioning member 3 to closely adhere to the rail top surface and the rail web, measure the distance between the long angle steel 7 and the center line 10. After the distance meets the requirements, draw the angle steel positioning line 20 on the track 6 through the angle steel positioning member 3. On the other side, use the same method to draw the angle steel positioning line 20 of another long angle steel 7;

[0079] Among them, as shown in Figure 9 Extend the center line 10 from the rail web to the rail top and keep the center line 10 perpendicular to the length direction of the track 6; and extend the angle steel positioning line 20 from the rail web to the rail top and keep the angle steel positioning line 20 perpendicular to the length direction of the track 6;

[0080] Then measure the distance from the center line 10 at the rail web to the angle steel positioning line 20, set it as L4, and then measure the distance from the center line 10 at the rail top to the angle steel positioning line 20, set it as L5. Then judge whether the error between L4 and L5 meets the specification requirements. If it does not meet the specification requirements, re - draw the line;

[0081] Among them, as shown in Figure 10As shown in the figure, after the angle steel positioning lines 20 on both the left and right sides are completed, measure the distance from the left angle steel positioning line 20 to the center line 10, set it as L6, then measure the distance from the right angle steel positioning line 20 to the center line 10, set it as L7, and then determine whether the error between L6 and L7 meets the specification requirements. If it does not meet the specification requirements, re-mark the lines.

[0082] Step Five: Repeat Step Three and Step Four to complete the marking of the center line 10 of the outer locking devices at the remaining three points and the angle steel positioning lines 20 of the long angle steels 7, and the L-shaped iron completes the marking of drilling holes in the rail waist of the rail.

[0083] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
