Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rail switch installation, and in particular to a rail hole positioning device for a turnout area. BACKGROUND

[0002] In the current rail transit system, the correct installation of the rail switch is crucial for the safe operation of the train. The traditional installation method usually relies on manual operation, using a ruler to mark the drilling position on the rail. Although this method can meet the installation requirements to some extent, it has significant limitations and problems in actual operation.

[0003] Firstly, when manually marking the drilling position on the rail with a ruler, the marking position often has a large error due to the technical level, fatigue level of the operator, and environmental factors. This error directly reflects the position deviation of the drilled hole on the rail, which further causes the holes on the two rails to not correspond accurately, and the parallel installation of the two installation rods cannot be achieved. Secondly, when drilling holes on the rail, the drilling tool is prone to slipping, which cannot provide accurate positioning holes, further increasing the installation error and difficulty.

[0004] In addition, the traditional installation method also has the problem of low efficiency, which requires multiple adjustments and corrections during the installation process, consuming a lot of time and labor cost. Therefore, the existing rail switch installation method needs to be improved to improve the installation accuracy, reduce the operation difficulty, and improve the installation efficiency. CONTENT OF THE INVENTION

[0005] In order to solve the problem of low positioning accuracy of manual drilling with a ruler during the installation of the switch, the present application provides a rail hole positioning device for a turnout area, which can quickly position the rail for drilling and is foldable for easy carrying.

[0006] According to one aspect of the present application, a rail hole positioning device for a turnout area is provided, which includes two sets of folding rods, one end of each set of folding rods being hinged; two sets of magnetic plates, each set of magnetic plates being provided at one end of the corresponding set of folding rods away from the hinge; wherein the magnetic plates are rotationally connected around the end wall of the folding rods, and the magnetic plates are magnetically connected to the rail; an impact locator, hinged to one end of the magnetic plate away from the folding rod; wherein the impact locator swings around the side wall of the magnetic plate.

[0007] In some embodiments, the cross section of the folding rod is semicircular; further comprising: a hinge, around which the two sets of folding rods swing; a sleeve, connected to the end of the folding rod near the hinge by a rope, and connected to the outer wall of one end of the two sets of folding rods.

[0008] In some embodiments, the magnetic plate has a notch at the end away from the folding rod, and the notch is located on the side of the magnetic plate away from the folding rod; the impact positioner is rotatably located on the inner wall of the notch; magnetic strips are provided on both outer walls of the magnetic plate, and the magnetic strips are magnetically connected to the rail.

[0009] In some embodiments, the impact positioner includes: one end of a strip block rotatably disposed on the inner wall of the cut; the strip block is an L-shaped structure, with the opening of the L-shaped structure located away from the rail; a spring plate, one end of which is connected to the inner wall of the opening of the L-shaped structure, and the other end pointing towards the end of the strip block away from the magnetic suction plate; a conical impact block, one end of which is disposed on the side of the spring plate near the opening of the L-shaped structure; and a conical positioning hole, disposed on the side of the opening of the L-shaped structure away from the spring plate; wherein the conical impact block is located inside the conical positioning hole, and the side of the spring plate away from the conical impact block is the striking surface.

[0010] In some embodiments, a first pin hole is provided at one end of the strip block near the cut; a second pin hole is provided on the inner wall of the cut; wherein the first pin hole and the second pin hole are used to connect pins.

[0011] In some embodiments, the end of the folding rod near the magnetic plate is provided with a mounting hole; the L rod has an external thread on its outer circumferential wall at one end; the L rod is located on the side of the folding rod near the rail; the end of the L rod near the external thread passes through the mounting hole and is bolted to the folding rod; the end of the L rod away from the external thread is located on the bottom surface of the rail.

[0012] The embodiments of this application have the following advantages.

[0013] The two folding rods are hinged at one end. Folding around the hinge allows them to be stored as a single rod. After folding, the magnetic plates connect magnetically, making storage easier. When marking holes, the magnetic plates adhere to the rails, preventing the positioning device from slipping due to impacts. After marking one side of the holes, the magnetic plates are swung around the end of the folding rod, causing them to adhere to the rail surface on the other side. This allows for marking holes on the other side of the rail, which is more convenient than manually marking holes with a ruler. Furthermore, the marked holes on both rails correspond perfectly, whereas manual marking is prone to errors.

[0014] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0035] To make the objectives, solutions, and advantages of the technical solutions of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0036] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] As described above, traditional rail drilling requires manual positioning using a ruler, and drilling is necessary on both sides of the rail. The manual positioning with a ruler results in low accuracy.

[0038] To at least partially address one or more of the aforementioned problems and other potential issues, an exemplary embodiment of this application provides a drilling and positioning device for rail 3 in a turnout area, comprising: two sets of folding rods 1, one end of each set of folding rods 1 being hinged; magnetic plates 2, provided in two sets, each set of magnetic plates 2 being disposed at the end of the two sets of folding rods 1 away from the hinge; wherein the magnetic plates 2 are rotatably connected around the end wall of the folding rods 1, and the magnetic plates 2 are magnetically connected to the rail 3; and an impact positioner 4, hinged to the end of the magnetic plates 2 away from the folding rods 1, wherein the impact positioner 4 swings around the side wall of the magnetic plates 2.

[0039] In the above embodiment, one end of the two folding rods 1 is hinged, and the two folding rods 1 are folded around the hinge to be stored into a single rod. After folding, the magnetic plates 2 are connected to each other by magnetic attraction, making it easier to store. At the same time, when marking holes, the magnetic plates 2 are magnetically attracted to the rails 3, which prevents the positioning device from sliding when the positioning device 4 is being struck or impacted during hole marking. After marking holes on one side, the magnetic plates 2 are swung around the end face of the folding rod 1, so that the magnetic plates 2 are magnetically attracted to the surface of the rails 3 on the other side of the folding rod 1, thereby marking holes on the other side of the rails 3. This is more convenient than manually marking holes with a ruler. At the same time, the marked holes on the two rails 3 correspond to each other, while manual hole marking is prone to errors.

[0040] Please see Figures 1-9In some embodiments, the cross-section of the folding rod 1 is semi-circular; it also includes: a hinge 5, with two sets of folding rods 1 swinging around the hinge 5; and a sleeve 6, with a rope connecting one end of the folding rod 1 near the hinge 5 and being engaged with the outer wall of one end of the two sets of folding rods 1.

[0041] In the above embodiment, the cross-section of the folding rod 1 is a semicircle, so that after folding, the folding rod 1 can be closed along the diameter of the semicircle. The sleeve 6 is fitted onto one end of the closed folding rod 1, and the other end of the folding rod 1 is magnetically attracted.

[0042] Please see Figures 1-9 In some embodiments, the magnetic plate 2 has a cutout 21 at the end away from the folding rod 1, and the cutout 21 is located on the side of the magnetic plate 2 away from the folding rod 1; the impact positioner 4 is rotatably located on the inner wall of the cutout 21; magnetic strips 22 are provided on both outer walls of the magnetic plate 2, and the magnetic strips 22 are magnetically connected to the rail 3.

[0043] In the above embodiment, the cutout 21 on the magnetic suction plate 2 is used to install the impact positioner 4. The impact positioner 4 swings after the magnetic suction plate 2 swings, thereby saving a set of magnetic suction plates 2. The swinging motion marks the holes on both sides of the rail 3.

[0044] Please see Figures 1-9 In some embodiments, the impact positioner 4 includes: one end of a strip block 41 rotatably disposed on the inner wall of the cut 21; the strip block 41 has an L-shaped structure, with the opening of the L-shaped structure located away from the rail 3; a spring plate 42, one end of which is connected to the inner wall of the opening of the L-shaped structure, and the other end pointing towards the end of the strip block 41 away from the magnetic suction plate 2; a conical impact block 43, one end of which is disposed on the side of the spring plate 42 near the opening of the L-shaped structure; and a conical positioning hole 44, disposed on the side of the opening of the L-shaped structure away from the spring plate 42; wherein the conical impact block 43 is located inside the conical positioning hole 44, and the side of the spring plate 42 away from the conical impact block 43 is the striking surface.

[0045] In the above embodiment, the spring sheet 42 and the strip block 41 are spaced apart. When the spring sheet 42 is struck, the conical impact block 43 passes through the conical positioning hole 44 and forms a marking point on the surface of the rail 3. The side of the conical impact block 43 near the rail 3 is a hard punch, and the concave point of the marking point can prevent the drill bit from slipping.

[0046] Please see Figures 1-9 In some embodiments, the strip block 41 has a first pin hole 45 at one end near the cut 21; the inner wall of the cut 21 has a second pin hole 46; wherein the first pin hole 45 and the second pin hole 46 are used to connect the pin 47.

[0047] In the above embodiment, when the strip block 41 is at a right angle to the magnetic plate 2, the strip block 41 is limited by inserting the pin 47 into the first pin hole 45 and the second pin hole 46, thereby avoiding the strip block 41 from tilting and causing an error in the distance between the two standard holes.

[0048] Please see Figures 1-9 In some embodiments, the end of the folding rod 1 near the magnetic plate 2 is provided with a mounting hole 11; the L rod 12 has an external thread on its outer circumferential wall at one end; the L rod 12 is located on the side of the folding rod 1 near the rail 3; the end of the L rod 12 near the external thread passes through the mounting hole 11 and is bolted to the folding rod 1; the end of the L rod 12 away from the external thread is located on the bottom surface of the rail 3.

[0049] In the above embodiment, the mounting hole 11 on the folding rod 1 is used to position the folding rod 1 and the rail 3 by the L rod 12 when the folding rod 1 is installed, thereby improving the error caused by the folding rod 1 sliding on the rail 3 when the folding rod 1 is swung to the other side after marking the mark hole on one side.
