Description

Technical Field

[0001] The utility model relates to the technical field of railway maintenance, and particularly to a replacement device for fouling marks. Background Art

[0002] A fouling mark is a sign used to indicate that when a locomotive or vehicle stops, it is not allowed to cross towards the turnout direction or the line intersection point direction, so as to prevent side collisions between the locomotives and vehicles staying on this line and those on the adjacent line; in addition, on the turnout at the exit of a station, the fouling mark is used to determine the position of the station boundary mark.

[0003] In recent years, during the process of standardization construction, it has been found that the surface of the fouling mark is weathered and damaged and cannot be reprinted, and the height of some fouling marks is insufficient due to the repeated tamping of turnouts to raise the switch ties. To ensure the safety of operating vehicles, guide the traffic flow, prevent collisions, remind of road condition changes and remind new people and other road users, it is necessary to replace the fouling marks in time. The existing replacement methods generally rely on manual prying of ballast or directly pulling out the fouling mark using simple tools such as crowbars and hemp ropes. However, the excavation of ballast is difficult, the amount of ballast prying is large, and it is extremely easy to damage the integrity of the fouling mark and the ballast bed. Summary of the Utility Model

[0044] The present utility model will be further described below in conjunction with the accompanying drawings.

[0045] A foulting mark is a sign used to indicate that when a locomotive or vehicle stops, it is not allowed to cross towards the turnout direction or the line intersection direction to prevent side collisions between the locomotives and vehicles staying on this line and those on the adjacent line; in addition, on the turnout at the exit of a station, the foulting mark is used to determine the position of the station boundary mark.

[0046] In recent years, during the standardization construction process, it has been found that the surface of the foulting mark is weathered and damaged and cannot be reprinted, and the height of some foulting marks is insufficient due to the repeated tamping of turnouts to raise the switch ties. To ensure the safety of operating vehicles, guide the traffic flow, prevent collisions, remind of road condition changes, and remind newbies and other road users, it is necessary to replace the foulting marks in a timely manner. The existing replacement methods generally rely on manually prying open the ballast or directly pulling out the foulting mark using simple tools such as pry bars and hemp ropes. However, the excavation of ballast is difficult, the amount of ballast prying is large, and it is extremely easy to damage the integrity of the foulting mark and the roadbed.

[0047] Embodiment 1

[0048] As Figure 1 、 Figure 8As shown in the figure, to solve the above technical problems, an embodiment of the utility model provides a replacement device for fouling marks, which includes an inner protection cylinder 10, an outer sleeve cylinder 20, a clamping part 30 and a prying component 40; one end of the inner protection cylinder 10 is inserted into the soil layer and sleeved outside the fouling mark 50 to be replaced; one end of the outer sleeve cylinder 20 is inserted into the soil layer and sleeved outside the inner protection cylinder 10; the clamping part 30 is arranged between the inner protection cylinder 10 and the fouling mark 50 to be replaced to connect the inner protection cylinder 10 and the fouling mark 50 to be replaced; the prying component 40 is arranged outside the soil layer and on one side of the outer sleeve cylinder 20. The prying component 40 is detachably connected to the top of the inner protection cylinder 10, and the prying component 40 is configured to be able to drive the inner protection cylinder 10 to leave the soil layer, and the fouling mark 50 to be replaced moves together with the inner protection cylinder 10.

[0049] As can be seen from the above, by arranging the inner protection cylinder 10 outside the fouling mark 50 to be replaced, it plays a protective role for the fouling mark 50 to be replaced, and the prying component 40 directly applies force to the inner protection cylinder 10, which can not only pull the inner protection cylinder 10 and the fouling mark 50 to be replaced out of the soil layer together, but also effectively prevent the fouling mark 50 to be replaced from being further damaged during the process of leaving the soil layer; at the same time, the construction area is small, only the inner protection cylinder 10 and the outer sleeve cylinder 20 need to be sleeved in sequence, and there is no need to dig out the ballast, so that not only the integrity of the ballast bed is less damaged, but also the labor intensity is reduced and the operation efficiency is greatly improved. By arranging the outer sleeve cylinder 20 outside the inner sleeve cylinder, it can not only isolate the inner protection cylinder 10 from the soil layer and the crushed stone layer, which is convenient for pulling out the inner protection cylinder 10, but also provide a guiding function for the installation of the new fouling mark, avoiding incorrect positions and skewing of the new fouling mark after replacement.

[0050] It should be noted that there is an annular space between the inner protection cylinder 10 and the fouling mark 50 to be replaced, and the clamping part is located in the annular space; the clamping part can be a wooden wedge, and the annular space is filled with the wooden wedge to lock the inner protection cylinder 10 and the fouling mark 50 to be replaced, ensuring that the fouling mark 50 to be replaced can move together with the inner protection cylinder 10 and be pulled out of the soil layer; in addition, the wooden wedge has an interference fit with the annular space, and the wooden wedge can be a rectangular strip, and its thickness is greater than the gap between the inner protection cylinder 10 and the fouling mark 50 to be replaced. For example, the gap between the inner protection cylinder 10 and the fouling mark 50 to be replaced is 3 mm, and the thickness of the wooden wedge is slightly greater than 3 mm.

[0051] It should also be noted that as Figure 6 、 Figure 7 shown, the inner protection cylinder 10 and the outer sleeve cylinder 20 can be driven into the soil layer by a pile driver 60. The impact force generated by the pile driver 60 itself provides a powerful hammering force, enabling the lower parts of the inner protection cylinder 10 and the outer sleeve cylinder 20 to be quickly and stably inserted into the ground.

[0052] It should also be noted that as Figure 1As shown, the upper surface of the soil layer is covered with a broken soil layer.

[0053] Embodiment 2

[0054] As Figure 1 、 Figure 8 As shown, the fouling mark replacement device includes an inner casing 10, an outer casing 20, a clamping portion 30 and a prying-up assembly 40; one end of the inner casing 10 is inserted into the soil layer and sleeved outside the fouling mark 50 to be replaced; one end of the outer casing 20 is inserted into the soil layer and sleeved outside the inner casing 10; the clamping portion 30 is arranged between the inner casing 10 and the fouling mark 50 to be replaced to connect the inner casing 10 and the fouling mark 50 to be replaced; the prying-up assembly 40 is arranged outside the soil layer and on one side of the outer casing 20, the prying-up assembly 40 is detachably connected to the top of the inner casing 10, and the prying-up assembly 40 is configured to be able to drive the inner casing 10 away from the soil layer, and the fouling mark 50 to be replaced moves together with the inner casing 10.

[0055] As can be seen from the above, by arranging the inner casing 10 outside the fouling mark 50 to be replaced, it plays a protective role for the fouling mark 50 to be replaced, and the prying-up assembly 40 directly applies force to the inner casing 10, which can not only pull the inner casing 10 and the fouling mark 50 to be replaced out of the soil layer together, but also effectively prevent the fouling mark 50 to be replaced from being further damaged during the process of leaving the soil layer; at the same time, the construction area is small, only the inner casing 10 and the outer casing 20 need to be sleeved in sequence, and there is no need to dig out the ballast, so that not only the integrity of the roadbed is less damaged, but also the labor intensity is reduced and the operation efficiency is greatly improved. By arranging the outer casing 20 outside the inner casing, it can not only isolate the inner casing 10 from the soil layer and the crushed stone layer, facilitate the extraction of the inner casing 10, but also provide a guiding function for the installation of the new fouling mark, and avoid the situation that the new fouling mark is incorrectly positioned or skewed after replacement.

[0056] It should be noted that there is an annular space between the inner casing 10 and the fouling mark 50 to be replaced, and the clamping member is located in the annular space; the clamping member can be a wooden wedge, and the annular space is filled with the wooden wedge to lock the inner casing 10 and the fouling mark 50 to be replaced, so as to ensure that the fouling mark 50 to be replaced can move together with the inner casing 10 and be pulled out of the soil layer; in addition, the wooden wedge is in interference fit with the annular space, and the wooden wedge can be a rectangular strip, and its thickness is greater than the gap between the inner casing 10 and the fouling mark 50 to be replaced. For example, the gap between the inner casing 10 and the fouling mark 50 to be replaced is 3 mm, and the thickness of the wooden wedge is slightly greater than 3 mm.

[0057] It also should be noted that as Figure 6 、 Figure 7As shown, the inner casing 10 and the outer casing 20 can be driven into the soil layer by a pile driver 60. The impact force generated by the pile driver 60 itself provides a powerful hammering force, enabling the lower parts of the inner casing 10 and the outer casing 20 to be quickly and stably inserted into the ground. The specific structure and working principle of the pile driver 60 are both prior arts and will not be elaborated in this application.

[0058] It should also be noted that, as Figure 1 shown, the upper surface of the soil layer is covered with a crushed soil layer.

[0059] As Figure 1 shown, in some embodiments, the upper end surface of the inner casing 10 is located above the upper end surface of the warning bumper 50 to be replaced, and the lower end surface of the inner casing 10 is not lower than the lower end surface of the warning bumper 50 to be replaced.

[0060] By defining that the upper end surface of the inner casing 10 is located above the upper end surface of the warning bumper 50 to be replaced and the lower end surface of the inner casing 10 is not lower than the lower end surface of the warning bumper 50 to be replaced, it is ensured that the inner casing 10 completely wraps the warning bumper 50 to be replaced, isolating the warning bumper 50 to be replaced from the soil layer and the crushed stone layer. Thus, not only can the protective effect be improved, but also it can be ensured that the warning bumper 50 to be replaced and the inner casing 10 are pulled out together.

[0061] It should be noted that, as Figure 1 shown, the lower end surface of the inner casing 10 is flush with the lower end surface of the warning bumper 50 to be replaced.

[0062] As Figure 2 shown, in some embodiments, scale marks 120 are provided on the outer wall of the inner casing 10.

[0063] By setting the scale marks 120, it is convenient to check the depth of the inner casing 10 inserted into the soil layer, greatly improving the convenience and practicality, and also ensuring that the lower end surface of the inner casing 10 is not lower than the lower end surface of the warning bumper 50 to be replaced.

[0064] It should be noted that the scale marks 120 can be plastic stickers directly pasted on the outer wall of the inner casing 10 or marked with a cutter. In addition, the scale marks 120 can be in centimeters.

[0065] It should also be noted that the warning bumper is a standard part with fixed dimensions. By measuring the dimensions of the warning bumper exposed on the ground, the depth of the warning bumper buried in the soil layer can be calculated, thereby determining the depth of the inner casing 10 that needs to be buried in the soil layer.

[0066] In some embodiments, the length of the outer casing 20 is not less than the length of the inner casing 10.

[0067] By limiting the length of the inner sleeve to be not less than the length of the inner casing 10, it is ensured that the outer sleeve 20 completely wraps the inner casing 10, isolating the inner casing 10 from the soil layer and the gravel layer, which facilitates the extraction of the inner casing 10.

[0068] It should be noted that, as Figure 1 shown, the length of the outer sleeve 20 is the same as the length of the inner casing 10.

[0069] As Figure 1 shown, in some embodiments, the outer sleeve 20 includes a first sleeve section 210 and a second sleeve section 220; the first sleeve section 210 is located within the soil layer;

[0070] The lower end surface of the second sleeve section 220 abuts against the upper end surface of the first sleeve section 210, and the upper end surface of the second sleeve section 220 is located outside the soil layer; wherein, the upper end surface of the first sleeve section 210 is located below the upper end surface of the inner casing 10, and the lower end surface of the first sleeve section 210 is not lower than the lower end surface of the inner casing 10.

[0071] By setting the outer sleeve 20 as a two-section structure including the first sleeve section 210 and the second sleeve section 220, it is convenient for disassembly and assembly; by limiting the upper end surface of the first sleeve section 210 to be located below the upper end surface of the inner casing 10, after the second sleeve section 220 is removed, it can be ensured that the upper end of the inner casing 10 is exposed, facilitating the connection between the upper end of the inner casing 10 and the prying component 40; by limiting the lower end surface of the first sleeve section 210 to be not lower than the lower end surface of the inner casing 10, it is ensured that the outer sleeve 20 completely wraps the inner casing 10, isolating the inner casing 10 from the soil layer and the gravel layer, which facilitates the extraction of the inner casing 10.

[0072] It should be noted that, as Figure 1 shown, the length of the first sleeve section 210 is less than the length of the inner casing 10, and the lower end surface of the first sleeve section 210 is flush with the lower end surface of the inner casing 10; in addition, the upper end surface of the upper sleeve is located above the soil layer.

[0073] It should also be noted that the first sleeve section 210 is first driven into the soil layer by a pile driver 60. When the upper end surface of the first sleeve section 210 is flush with the upper end surface of the inner casing 10, the second sleeve section 220 is then placed on the upper end surface of the first sleeve section 210, and the first sleeve section 210 is continuously driven into the soil layer by the pile driver 60 with the aid of the second sleeve section 220 until the lower end surface of the first sleeve section 210 is flush with the lower end surface of the inner casing 10.

[0074] As Figure 3As shown, in some embodiments, a plurality of limiting ear plates 2201 are provided on the outer wall of the second sleeve segment 220, and the plurality of limiting ear plates 2201 are arranged circumferentially around the second sleeve segment 220; wherein, the lower end surface of the limiting ear plate 2201 is located below the lower end surface of the second sleeve segment 220.

[0075] The limiting lugs 2201 are provided to limit the second sleeve section 220 , thereby preventing the second sleeve section 220 from sliding relative to the first sleeve section 210 and affecting the insertion of the second sleeve section 220 into the soil layer.

[0076] It should be noted that the ear plate is connected to the second sleeve section 220 by welding.

[0077] like Figure 4 , Figure 8 As shown, in some embodiments, the prying assembly 40 includes a support frame 410, a crowbar 420 and a connecting rope 430; a limiting groove 4101 is provided on the support frame 410; the crowbar 420 is movably provided in the limiting groove 4101; one end of the connecting rope 430 is detachably connected to the inner casing 10 and the other end is detachably connected to the crowbar 420.

[0078] By movably setting the crowbar 420 in the limiting groove 4101, the connecting rope 430 is detachably connected to the crowbar 420, and utilizing the principle of leverage, with the limiting groove 4101 as a fulcrum, the staff applies force to the end of the crowbar 420 away from the connecting rope 430, so that the end of the crowbar 420 away from the connecting rope 430 is pressed down, thereby lifting the inner casing 10, and the warning mark 50 to be replaced is pulled out together with the inner casing 10.

[0079] It should be noted that the limiting groove 4101 can be arc-shaped. The crowbar 420 passes through the limiting groove 4101. The limiting groove 4101 limits the crowbar 420, reduces the forward and backward shaking of the crowbar 420 during work, and facilitates the staff to apply force.

[0080] It should also be noted that if Figure 4 As shown, the support frame 410 can be a tripod; the connecting rope 430 can be an open-loop rope or an iron chain; in addition, female buckles and male buckles can be respectively provided at both ends of the connecting rope 430. After the connecting rope 430 passes through the second annular member 4402 and the through hole 110, it is connected to the male buckle through the female buckle.

[0081] In some embodiments, the crowbar 420 assembly further includes a connecting member 440, and the connecting member 440 includes a first annular member 4401 and a second annular member 4402; the first annular member 4401 is sleeved on the crowbar 420; the second annular member 4402 is connected to the outer wall of the first annular member 4401, the second annular member 4402 is parallel to the first annular member 4401, and the second annular member 4402 is for the connecting rope 430 to pass through.

[0082] The crowbar 420 assembly is connected to the connecting rope 430 through the connecting member 440; by sleeving the first annular member 4401 on the crowbar 420, the first annular member 4401 can slide on the crowbar 420 to adjust the position of the first annular member 4401, thereby playing a role in adjusting the torque, ensuring that the staff can pull out the inner casing 10 and the replacement fouling mark 50 with less force, further reducing the labor intensity and improving the work efficiency.

[0083] As Figure 5 、 Figure 8 shown, in some embodiments, a through hole 110 for the connecting rope 430 to pass through is provided at the top of the inner casing 10.

[0084] It should be noted that the through hole 110 provides a structural basis for the installation of the connecting rope 430; the number of the through holes 110 can be four, and the four through holes 110 are arranged at equal intervals circumferentially around the inner casing 10.

[0085] In some embodiments, there is an annular space between the outer sleeve 20 and the inner casing 10, and the annular space is 10 mm.

[0086] The specific process of replacing the fouling mark by the fouling mark replacement device provided by the present utility model is as follows:

[0087] As Figure 6 shown, the inner casing 10 is driven into the soil layer by a pile driver 60 until the lower end surface of the inner casing 10 is flush with the lower end surface of the replacement fouling mark 50, and the inner casing 10 is sleeved outside the replacement fouling mark 50; the clamping member is clamped between the inner casing 10 and the replacement fouling mark 50 to connect the inner casing 10 and the replacement fouling mark 50;

[0088] As Figure 7 shown, the first sleeve section 210 is driven into the soil layer by a pile driver 60 until the upper end surface of the first sleeve section 210 is flush with the upper end surface of the inner casing 10, and the first sleeve section 210 is sleeved outside the inner casing 10;

[0089] The lower end surface of the second sleeve section 220 is abutted against the upper end surface of the first sleeve section 210, and the second sleeve section 220 is driven into the soil layer by a pile driver 60, and the first sleeve section 210 and the second sleeve section 220 move until the upper end surface of the second sleeve section 220 is flush with the upper end surface of the inner casing 10.

[0090] As Figure 8 shown, remove the second sleeve section 220, the upper end of the inner casing 10 is exposed, erect the support frame 410 and the crowbar 420, and both ends of the connecting rope 430 are respectively connected to the inner casing 10 and the crowbar 420; pry the inner casing 10 with the crowbar 420 to pull out the inner casing 10 and the replacement fouling mark 50;

[0091] Insert a new fouling mark into the first sleeve section 210, tamp the soil layer, and fasten the new fouling mark.

[0092] Although the present utility model has been described with reference to the preferred embodiments, various modifications can be made to it and components thereof can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way. The present utility model is not limited to the specific embodiments disclosed in the text, but includes all technical solutions falling within the scope of the claims.
