Description
Technical Field
[0001] This utility model relates to the field of track installation technology, and more specifically, to a marking template for laying sleepers. Background Technology
[0002] Currently, same-side hyperbolic turnouts are rarely installed in China, and the placement of sleepers is the most difficult aspect, especially for large-number turnouts. All sleepers gradually twist relative to each other, so sleeper placement cannot be adjusted based on the straight track as in other turnouts.
[0003] Since there is no unified reference for adjusting all sleepers, a reference can be artificially created and drawn on the sleepers before adjusting them. For this purpose, a layout diagram of the sleepers for the double-curved turnout on the same side can be pre-drawn. Then, two lines can be drawn, passing through all sleepers, and the distance between the center points of the sleepers on these two lines can be marked. Sufficient distance must be maintained between the two lines to ensure the accuracy of sleeper torsion. Based on the layout diagram, this line is drawn on the actual sleepers, thus serving as the reference for sleeper adjustment.
[0004] Ensuring the accuracy of marking lines on sleepers is a pressing problem that needs to be solved. Utility Model Content
[0005] The purpose of this utility model is to provide a marking template for laying sleepers, which can ensure the accuracy of the lines drawn on the sleepers.

[0034] The following describes in detail, with reference to the accompanying drawings, the specific structure of a marking template for laying sleepers provided by this utility model and the corresponding technical effects it brings.
[0035] Go to reference Figures 1-3 The present invention provides a marking template 1 for laying sleepers, comprising a base plate 100, a fixing pin 200, and a movable pin 300. The base plate 100 has a first end 101 and a second end 102 opposite to each other along its own length direction. The base plate 100 is provided with a groove 151 extending along its own length direction, the groove 151 being located between the first end 101 and the second end 102. The base plate 100 has a bottom surface 103 and a top surface 104 opposite to each other along its thickness direction. The bottom surface 103 is used to abut against the sleepers, and the top surface 104 is provided with a scale. The fixing pin 200 is fixed to one end of the base plate 100, and the movable pin slides and moves within the groove 151. The fixing pin 200 and the movable pin 300 are arranged at intervals along the length direction of the base plate 100.
[0036] Understandably, when marking lines on the sleepers, the fixing pins 200 on the base plate 100 can be aligned with the pre-set positioning holes on the sleepers to ensure that the base plate 100 is stably fixed on the sleepers. Then, according to the design drawing, the position of the movable pins 300 can be adjusted to align with the points that need to be marked, thereby ensuring the accuracy of the sleeper marking. Understandably, since the top surface 104 is equipped with a scale, the accuracy of the marking can also be further improved by setting the scale.
[0037] Optionally, in some alternative embodiments, in order to facilitate the installation and removal of the fixing pin 200, the fixing pin 200 can be detachably connected to the base plate 100 by a fastener, wherein the fastener can be a pin fastener or a threaded fastener.
[0038] Of course, in some other embodiments, the fixing pin 200 can also be welded to the substrate 100 to ensure the connection strength between the fixing pin 200 and the substrate 100.
[0039] In detail, in this embodiment, the substrate 100 includes a first connecting plate 110, a second connecting plate 120, a third connecting plate 130 and a fourth connecting plate 140 connected end to end in sequence. The first connecting plate 110 and the third connecting plate 130 are arranged at intervals along the length direction, and the second connecting plate 120 and the fourth connecting plate 140 are arranged at intervals along the width direction of the substrate 100 and extend along the length direction. The fixing pin 200 is fixed to the first connecting plate 110, that is, the first connecting plate 110 is located at the first end 101 of the substrate 100.
[0040] Understandably, the substrate 100 is formed by the first connecting plate 110, the second connecting plate 120, the third connecting plate 130 and the fourth connecting plate 140 connected end to end. That is, the substrate 100 has a through hole in the middle. The through hole can reduce the weight of the substrate 100 and reduce the load on the operator when the operator holds the substrate 100 to scribing.
[0041] Furthermore, the substrate 100 in this embodiment also includes a fifth connecting plate 150. The two ends of the fifth connecting plate 150 are connected to the first connecting plate 110 and the third connecting plate 130, respectively. The fifth connecting plate 150 is provided with a sliding groove 151. It can be understood that the sliding groove 151 is provided on the fifth connecting plate 150.
[0042] Of course, in some other embodiments, the slide 151 may also be provided on the second connecting plate 120 or the fourth connecting plate 140.
[0043] In this embodiment, the two ends of the fifth connecting plate 150 are connected to the middle of the first connecting plate 110 and the middle of the third connecting plate 130, respectively. Therefore, the groove 151 is generally located in the middle of the substrate 100, and when scribing is performed by scribing template 1, the substrate 100 can be kept in a generally flat state.
[0044] In detail, in this embodiment, the movable pin 300 is also fitted with a baffle 310. The size of the baffle 310 is larger than the size of the slide groove 151. The baffle 310 is fixedly connected to the movable pin 300. The baffle 310 can be welded or snapped to the movable pin 300.
[0045] Understandably, in some embodiments, the scribing template 1 also includes a locking member for connecting with the movable pin 300. The locking member is used to lock or unlock the movable pin 300 to the substrate 100. For example, the locking member can be a nut. The movable pin 300 has external threads. When locking, the locking member can be screwed into the movable pin 300, and the locking member abuts against the end face of the substrate 100, thereby locking the movable pin 300 to the substrate 100. When unlocking, simply move the locking member to disengage it from the substrate 100, thus unlocking the movable pin 300 from the substrate 100.
[0046] Specifically, the fixing pin 200 is welded to the middle of the substrate 100 in its width direction. In this embodiment, the fixing pin 200 is welded to the middle of the width direction of the first connecting plate 110 to ensure that the fixing pin 200 and the movable pin 300 are spaced apart in the length direction of the substrate 100.
[0047] To ensure the strength of the substrate 100, the first connecting plate 110, the second connecting plate 120, the third connecting plate 130, the fourth connecting plate 140 and the fifth connecting plate 150 are integrally formed.
[0048] Optionally, in some embodiments, in order to further improve the strength of the substrate 100, a reinforcing plate is provided between the second connecting plate 120 and the fifth connecting plate 150, and a reinforcing plate is also provided between the fourth connecting plate 140 and the fifth connecting plate 150.
[0049] At least one of the top surfaces 104 of the second connecting plate 120 and the fourth connecting plate 140 is provided with a scale. In this embodiment, both the top surfaces 104 of the second connecting plate 120 and the fourth connecting plate 140 are provided with scales. By setting the scales, the marking personnel can be prompted about the marking length when marking lines, thus ensuring the marking accuracy of the workers.
[0050] Optionally, the ruler is attached to the top surface 104 of the second connecting plate 120, or the ruler is attached to the top surface 104 of the fourth connecting plate 140. That is, in this embodiment, the top surface 104 of the second connecting plate 120 is attached with a ruler, and the top surface 104 of the fourth connecting plate 140 is attached with a ruler.
[0051] Optionally, in some other embodiments, the scale is engraved on the top surface 104 of the second connecting plate 120, or the scale is engraved on the top surface 104 of the fourth connecting plate 140. That is, the top surface 104 of the second connecting plate 120 is engraved with a scale, and the top surface 104 of the fourth connecting plate 140 is engraved with a scale. In other words, the top surface 104 of the second connecting plate 120 is engraved with a scale, and the top surface 104 of the fourth connecting plate 140 is engraved with a scale.
[0052] In this embodiment, in order to facilitate the operator to hold the marking template 1, the top surface 104 of the substrate 100 is provided with a handle 160. Specifically, in this embodiment, multiple handles 160 are provided, and the multiple handles 160 are arranged at intervals along the length direction of the substrate 100.
[0053] It should be noted that "multiple" in this embodiment can be understood as two or more quantities. Of course, in some embodiments, the number of handles 160 can also be one.
[0054] One end of the handle 160 is connected to the second connecting plate 120, and the other end of the handle 160 is connected to the fourth connecting plate 140.
[0055] To ensure the connection strength between the handle 160 and the substrate 100, the handle 160 is welded to the substrate 100.
[0056] In summary, the marking template 1 for laying sleepers provided in this embodiment of the present invention includes a base plate 100, a fixing pin 200, and a movable pin 300. The base plate 100 has a first end 101 and a second end 102 opposite to each other along its own length direction. The base plate 100 is provided with a groove 151 extending along its own length direction. The groove 151 is located between the first end 101 and the second end 102. The base plate 100 has a bottom surface 103 and a top surface 104 opposite to each other along its thickness direction. The bottom surface 103 is used to abut against the sleeper. The top surface 104 is provided with a scale. The fixing pin 200 is fixed to one end of the base plate 100. The movable pin slides and engages with the groove 151 and can move within the groove 151. The fixing pin 200 and the movable pin 300 are arranged at intervals along the length direction of the base plate 100. When marking lines on the sleepers, the fixing pins 200 on the base plate 100 can be aligned with the pre-set positioning holes on the sleepers to ensure that the base plate 100 is stably fixed on the sleepers. Then, according to the design drawing, the position of the movable pins 300 can be adjusted to align with the points to be marked, thereby ensuring the accuracy of the sleeper marking. It is understandable that since the top surface 104 is equipped with a scale, the accuracy of the marking can also be further improved by setting the scale.
[0057] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
