Description

Technical Field

[0001] The present application relates to the technical field of operating tools, and in particular to a method for using a rail sawing machine. Background Art

[0002] With the rapid development of high-speed railways and urban rail transit, the speed and quality requirements of rail transit construction are constantly increasing. When laying and repairing tracks, it is often necessary to cut rails, so various types of rail sawing machines have been derived. However, the rail sawing machine bracket in the prior art is usually a split structure, which is prone to vibration errors, or the load-bearing part of the bracket is a plate structure with low rigidity. Under the action of the tensioning force of the transmission device and the centrifugal force of the grinding wheel, the load-bearing part of the bracket is easily deformed, thereby causing cutting deviations, resulting in low cutting accuracy, and the flatness of the cutting plane usually does not reach 0.3mm. Moreover, when the rail sawing machine in the prior art cuts the rails on both sides, sparks will inevitably spray upwards, and the spraying distance is far, and the danger of on-site construction is extremely high. Summary of the invention

[0003] In view of this, the present invention provides a method for using a rail sawing machine, so that the rail sawing machine can improve the cutting accuracy when cutting rails, and can further avoid the phenomenon of sparks generated by cutting spraying upwards, thereby improving the safety of operation.

[0035] In order to make the technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] like Figures 1 to 3As shown, the present invention provides a method for using a rail sawing machine, the rail sawing machine comprising: a driving device 1, an integrated box-shaped bracket 2, a grinding wheel 3 and a support arm 5; the driving device 1 for driving the grinding wheel to rotate is fixed to the rear of the first side surface of the integrated box-shaped bracket 2, and the grinding wheel 3 is installed on the front of the first side surface; a spacing sleeve 21 is arranged at the middle position of the integrated box-shaped bracket 2, and both ends of the spacing sleeve 21 extend outward by a preset length; the end of the support arm 5 is connected to the first end or the second end of the spacing sleeve 21, and the bottom end of the support arm 5 has a rail clamping device 6;

[0037] The method of use comprises the following steps:

[0038] Step 101, clamping the rail clamping device 6 at the bottom end of the support arm 5 at a corresponding position on the rail 101;

[0039] Step 102, setting the support arm 5 to a first state, connecting the first end of the spacer sleeve 21 of the integrated box-type bracket to the end of the support arm 5, starting the driving device 1, and cutting the first side of the rail;

[0040] Step 106, until the entire rail is cut, the driving device is turned off, the rail clamping device 6 is removed, and the cutting operation is completed.

[0041] In the technical solution of the present invention, when the grinding wheel is not worn, the first side of the rail can be cut to the bottom. Through the above steps, the first end of the adjustable sleeve 21 of the integrated box-type bracket is connected to the end of the support arm 5 (refer to Figure 2 , at this time, the grinding wheel 3 and the support arm 5 are respectively located on both sides of the integrated box-shaped bracket 2), and the rail cutting operation is performed on the first side of the rail. During the entire cutting process, since the rail sawing machine bracket 2 is integrated, the split design is avoided, and the vibration error caused by the large number of structures is avoided. By designing it into a box shape, the rigidity is improved on the basis of ensuring the weight, and the error caused by deformation is reduced, thereby significantly improving the cutting accuracy; further, during the entire cutting process, the grinding wheel rotates downward (i.e. Figure 3 The rail is cut in the direction of the middle arrow, so the sparks generated by the grinding wheel are also ejected downwards and will not radiate to the surrounding area.

[0042] In addition, in the technical solution of the present invention, the grinding wheel 3 and the driving device 1 are both located on the first side of the integrated box-type bracket 2, that is, the same side, instead of the grinding wheel 3 and the driving device 1 being respectively located on both sides of the integrated box-type bracket 2, so that the support arm 5 and the integrated box-type bracket 2 can be installed at a short distance, which can effectively reduce the volume of the rail sawing machine, making the structure more compact, lighter and more portable.

[0043] In addition, preferably, in a specific embodiment of the present invention, Figure 3As shown, the support arm 5 may include a first arm body 51 and a second arm body 52, wherein the bottom end of the first arm body 51 is rotatably connected to the rail clamping device 6, the top end of the first arm body 51 is rotatably connected to one end of the second arm body 52, and the other end of the second arm body 52 is rotatably connected to the first end or the second end of the spacing sleeve 21. Through the above arrangement, the first arm body and the second arm body of the support arm can be rotated or flipped to be in different states to achieve cutting of different sides or different positions of the rail, which is more flexible and convenient for control.

[0044] As an example, in a preferred embodiment of the present invention, Figure 3 As shown, the first state may refer to the support arm 5 being located at the first side of the rail (i.e. Figure 3 The first arm body and the second arm body have an angle opening downward.

[0045] In the technical solution of the present invention, a variety of implementation methods can be used to implement the above-mentioned method of using the rail sawing machine. The technical solution of the present invention will be described in detail below by taking several implementation methods as examples.

[0046] For example, preferably, in a specific embodiment of the present invention, Figures 4 to 6 As shown, the following steps may also be included between step 102 and step 106:

[0047] Step 103, removing the first end of the adjustable sleeve 21 of the integrated box-shaped bracket from the end of the support arm 5;

[0048] Step 104, setting the support arm 5 to the second state, connecting the second end of the adjustable shaft sleeve 21 of the integrated box-shaped bracket to the end of the support arm 5;

[0049] Step 105, adjusting the extension length of the second end of the spacer sleeve 21 so that the grinding wheel corresponds to the cutting seam on the first side of the rail, and cutting the second side of the rail.

[0050] In the cutting operation of the rail, a one-cut method is usually adopted when the grinding wheel is not worn. When the grinding wheel is worn, the rail is often not cut to the bottom on one side. In this case, a double-sided cutting method is used. In the technical solution of the present invention, an integrated box-shaped bracket 2 is provided, and an adjusting sleeve 21 is provided thereon, so that the ends of the support arm can be connected to the first end and the second end of the adjusting sleeve respectively, so as to cut the two sides of the rail respectively. For example, referring to Figure 2 and Figure 3 , the support arm 5 is located at the first side of the rail, and the end of the support arm is connected to the first end of the spacer sleeve 21 (refer to Figure 2, at this time, the grinding wheel 3 and the support arm 5 are respectively located on both sides of the integrated box-shaped bracket 2), so that the first side of the rail can be cut. At this time, the grinding wheel rotates downward (i.e. Figure 3 (in the direction of the arrow in the middle), which can ensure that the spark sprays downward; refer to Figure 5 and Figure 6 , flip the support arm 5 to the second side of the rail, and connect the end of the support arm to the second end of the spacer sleeve 21 (refer to Figure 5 , at this time, the grinding wheel 3 and the support arm 5 are located on the same side of the integrated box-shaped bracket 2), so that the second side of the rail can be cut, and at this time, the grinding wheel can also be ensured to rotate downward (i.e. Figure 6 Therefore, by setting the adjustable sleeve 21 on the integrated box-type bracket, when cutting both sides of the rail, the ends of the support arm 5 are respectively connected to the two ends of the adjustable sleeve 21, so that the grinding wheel can always rotate downward, so that the sparks generated by cutting are sprayed downward, and the safety of the on-site personnel is guaranteed.

[0051] As an example, in a preferred embodiment of the present invention, Figure 6 As shown, the second state may refer to the support arm 5 being located at the second side of the rail (i.e. Figure 6 The left side of the rail in the middle), and the angle between the first arm body and the second arm body opens downward.

[0052] Furthermore, preferably, in a specific embodiment of the present invention, during the time between cutting the first side and the second side of the rail, the drive device 1 can be in an idle state, thereby facilitating the disassembly and assembly of the support arm and the integrated box-type bracket.

[0053] In addition, further, in a preferred specific embodiment of the present invention, the step 105 may further include:

[0054] Step 51, using a tool to adjust the extension length of the second end of the spacing sleeve 21, and measuring the distance between the center of the grinding wheel and the cutting seam on the first side of the rail;

[0055] Step 52, if the distance between the grinding wheel center and the cutting seam on the first side of the rail is zero, then cut the second side of the rail; otherwise, continue to execute step 51.

[0056] In the technical solution of the present invention, the spacing sleeve 21 can be interference-fitted on the integrated box-shaped bracket. When the ends of the support arm are respectively installed on the two ends of the spacing sleeve, the position of the grinding wheel center is pre-designed to preliminarily ensure that when cutting the second side of the rail, the grinding wheel center corresponds to the cutting seam on the first side. When the actual operation of cutting the rail on both sides is performed, the extension length of the second end of the spacing sleeve 21 is measured and fine-tuned using the tooling to further accurately ensure the cutting seam between the grinding wheel center and the first side of the rail, and ensure the cutting accuracy when cutting on both sides.

[0057] For another example, preferably, in another specific embodiment of the present invention, Figure 7 and Figure 8 As shown, the following steps may also be included between step 102 and step 106:

[0058] Step 103 ′, setting the support arm to the third state, driving the integrated box-shaped bracket 2 and the grinding wheel 3 to change positions, and then cutting the second side of the rail.

[0059] In special cases, if the second side of the rail needs to be cut quickly, in the technical solution of the present invention, in order to improve the cutting efficiency, it is also possible to directly flip the support arm over to the second side of the rail after cutting the first side of the rail without disassembling the support arm on the spacing sleeve, so that the support arm is flipped to the second side of the rail, and at the same time drive the rail sawing machine bracket 2 and the grinding wheel 3 to a position convenient for cutting the second side of the rail, for example, Figure 8 As shown in the figure, the rail saw machine is in a vertical cutting state, which can achieve the continued cutting of the second side of the rail. This process does not require the disassembly of the support arm, and the operation is simple and fast. However, this state will cause the grinding wheel to rotate upward (i.e. Figure 8 Therefore, in order to ensure the safety of on-site construction, the support arm 5 should be disassembled as much as possible to ensure that the sparks are directed downward when the rails are cut on both sides, thereby ensuring safety.

[0060] As an example, in a preferred embodiment of the present invention, Figure 8 As shown, the third state may refer to that the support arm 5 is located at the second side of the rail, and the angle between the first arm body and the second arm body thereof is open forward.

[0061] In addition, preferably, in a specific embodiment of the present invention, Fig. 9As shown, a limiting crossbeam 61 can also be provided on the rail clamping device 6, which is located below the bottom end of the support arm 5 and is used to limit the support arm 5. Since the rail sawing machine is in the vertical cutting state, it is necessary to manually lift the rail sawing machine upward to overcome the self-weight of the rail sawing machine. By providing the limiting crossbeam 61, when the bottom end of the first arm body 51 of the support arm rotates to a certain position relative to the rail clamping device 6, the limiting crossbeam 61 limits the first arm body 51, so that it no longer rotates, thereby preventing the bottom end of the first arm body from rotating infinitely during the cutting process and causing difficulty in control. In addition, the use of the limiting crossbeam 61 to support the support arm can also bear part of the deadweight of the rail sawing machine, thereby achieving the purpose of saving the operator more effort.

[0062] In addition, as an example, in a preferred embodiment of the present invention, Figure 8 and Fig. 9 As shown, the lengths of the first arm body 51 and the second arm body 52 of the support arm 5 have a preset ratio, and the first arm body 51 is longer than the second arm body 52 .

[0063] In the technical solution of the present invention, by reasonably designing the length of the first arm body 51 and the second arm body 52 of the support arm, the length of the first arm body is made longer than the second arm body 52, so that when the rail sawing machine is in the vertical cutting state to cut the second side of the rail, the grinding wheel can be mainly located above the second side of the rail and cut directly downward without causing the grinding wheel to still fall above the first side of the rail, resulting in failure to cut to the bottom or inconvenience in flexible operation.

[0064] To sum up, in the technical scheme of the present invention, by reasonably designing and using the rail sawing machine in the present invention, the rigidity of the rail sawing machine can be improved, errors caused by vibration and deformation can be avoided, and the cutting accuracy can be improved; further, in the process of cutting both sides of the rails, the grinding wheel can be rotated downward to cut the rails, so that sparks are sprayed downward when cutting both sides of the rails, which greatly improves the safety of the rail cutting operation.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
