Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the field of devices for removing ice and snow from railway tracks using heating methods, and in particular to a heating assembly for an outer locking device of a railway turnout. BACKGROUND

[0002] The statements herein are merely provided to give general background information on the present application, and do not necessarily constitute the prior art.

[0003] A turnout is a line connection device of a railway track structure, and mainly includes a fixed and immovable main track, a movable frog, and an outer locking device. The outer locking device is used to unlock or lock the frog from the main track, so as to change the contact state of the frog and the main track, and enable a locomotive and vehicle to turn into or pass through another track. In winter, ice and snow may block the outer locking device, resulting in that the turnout cannot work normally, and further affecting the normal operation of the railway. An electric heating turnout snow melting device can heat the outer locking device, thereby effectively solving the problem that the turnout cannot work normally due to ice and snow blocking the outer locking device in winter, and plays an important role in railway operation.

[0004] At present, when the electric heating turnout snow melting device is used for snow melting, there are still many limitations. SUMMARY

[0005] In the following, a brief overview of the present application is given to provide a basic understanding of some aspects of the present application. It should be understood that this overview is not an exhaustive overview of the present application. It is not intended to identify key or important parts of the present application nor is it intended to limit the scope of the present application. Its purpose is merely to present some concepts in a simplified form as a prelude to the more detailed description to be discussed later.

[0006] In view of the above problems, embodiments of the present application provide a heating assembly for an outer locking device of a railway turnout, which comprises a locking frame heating assembly for heating a roller type locking frame of the outer locking device of the railway turnout. The locking frame heating assembly comprises two locking frame heating pieces and a heating connecting piece for connecting the two locking frame heating pieces. Each locking frame heating piece is used to heat an extension of a frame body of the roller type locking frame. Each locking frame heating piece comprises a planar heating piece, a heating piece support plate, and a heating mounting piece. The planar heating piece is used to provide heat to heat the extension of the frame body. The heating piece support plate is arranged on a side surface of the extension opposite to the locking frame mounting piece, and the planar heating piece is arranged on a side surface of the heating piece support plate facing the extension. The heating mounting piece is used to abutly mount the heating piece support plate and the extension to the extension.

[0007] The railway turnout outer locking device heating assembly provided by the embodiment of the present application heats the two extension portions of the frame body by the planar heating pieces of the two locking frame heating pieces, can melt the ice and snow on the locking frame of the railway turnout outer locking device, avoids the ice and snow from blocking the locking frame, and has the advantages that, since the planar heating pieces are adopted, the heating area and the heating uniformity can be improved, so that the frame body of the locking frame is uniformly heated, the heating efficiency is improved, the effect of melting the ice and snow is improved, and mechanical damage caused by non-uniform heating is reduced; since the planar heating pieces are arranged on the side surface of the heating piece support plate facing the extension portion, the heating piece support plate and the extension portion are abuttingly mounted on the extension portion by the heating mounting piece, so that the planar heating pieces can directly contact the extension portion, the heat of the planar heating pieces can be directly conducted to the frame body, the heating efficiency is greatly improved, and the snow melting effect is improved.

[0035] In the following, exemplary embodiments of the present application will be described with reference to the drawings. In the description, not all the features of the actual embodiments are described in order to make the description clear and brief. However, it should be appreciated that many embodiment-specific decisions must be made in the process of developing any such actual embodiment in order to implement the specific goals of the developer, such as compliance with those system- and business-related constraints that can vary from one embodiment to another. Moreover, it should be appreciated that, while the development work can potentially be very complex and time-consuming, it would be a routine undertaking for those with ordinary skill in the art having the benefit of this disclosure.

[0036] It should also be noted that, in order not to obscure the application with unnecessary detail, only the structures of the equipment and / or the processing steps that are closely related to the solution according to the present application are shown in the drawings, and other details that are not closely related to the present application are omitted.

[0037] In the related art, the heating piece for heating the locking frame is usually arranged on the side surface of the locking frame. The present inventor has found that, since the side surface of the locking frame is usually not a machining surface, the side surface of the locking frame is not flat enough, and the heating efficiency of the heating piece for heating the locking frame is low, and the effect of melting ice and snow is poor.

[0038] In view of the above problems, the embodiments of the present application provide a railway turnout outer locking device heating assembly.

[0039] Referring to Figure 1 , the locking frame heating assembly 10 of the railway turnout outer locking device heating assembly provided by the embodiments of the present application is assembled with the roller type locking frame 300 of the railway turnout outer locking device, and a structure schematic diagram after assembly is shown. The railway turnout outer locking device heating assembly can include a locking frame heating assembly for heating the roller type locking frame 300 of the railway turnout outer locking device.

[0040] Referring to Figure 1 and Figure 2 , Figure 2 is Figure 1 a structural schematic view of the locking frame heating assembly 10 shown from another angle, in which the heating connecting member 12 is omitted. Each locking frame heating member 11 can include a planar heating member 111, a heating member support plate 112, and a heating mounting member 113. The planar heating member 111 is configured to provide heat to heat an extension 3011 of the frame body 301. The heating member support plate 112 is arranged on a side surface of the extension 3011 opposite to the locking frame mounting member. The planar heating member 111 is arranged on a side surface of the heating member support plate 112 facing the extension 3011. The heating mounting member 113 is configured to abutly mount the heating member support plate 112 and the extension 3011 to the extension 3011.

[0041] Referring to Figure 1 , Figure 2 and Figure 3 , Figure 3 is Figure 2 a structural schematic view of the locking frame heating assembly 10 shown from another angle, in which the heating connecting member 12 is omitted. Each locking frame heating member 11 can include a planar heating member 111, a heating member support plate 112, and a heating mounting member 113. The planar heating member 111 is configured to provide heat to heat an extension 3011 of the frame body 301. The heating member support plate 112 is arranged on a side surface of the extension 3011 opposite to the locking frame mounting member. The planar heating member 111 is arranged on a side surface of the heating member support plate 112 facing the extension 3011. The heating mounting member 113 is configured to abutly mount the heating member support plate 112 and the extension 3011 to the extension 3011.

[0042] The railway turnout outer locking device heating assembly provided by the embodiments of the present application can provide heat to heat two extensions 3011 of the frame body 301 through two planar heating members 111 of two locking frame heating members 11, can melt ice and snow on the locking frame 300 of the railway turnout outer locking device, and can avoid blocking the locking frame 300 by ice and snow. In addition, the planar heating member 111 is adopted, which is beneficial to improving the heating area and the heating uniformity, thereby ensuring that the frame body 301 of the locking frame 300 is uniformly heated, is beneficial to improving the heating efficiency and the effect of melting ice and snow, and avoids mechanical damage of the railway turnout outer locking device caused by uneven heating. Meanwhile, the planar heating member 111 is arranged on a side surface of the heating member support plate 112 facing the extension 3011, and the heating member support plate 112 and the extension 3011 are abutly mounted to the extension 3011 through the heating mounting member 113, so that the planar heating member 111 can directly contact the extension 3011, and the heat of the planar heating member 111 can be directly conducted to the frame body 301, thereby greatly improving the heating efficiency and the snow melting effect.

[0043] In some embodiments, the railway turnout outer locking device can include locking frames arranged on both sides of the main track and a locking rod 400 arranged below the main track.

[0044] The railway turnout outer locking device can be an HRS type outer locking device. The locking frame of the HRS type outer locking device is a roller type locking frame 300. The roller type locking frame 300 can include a frame body 301 and a frame mounting portion 302 for mounting the frame body 301 to a locking frame mounting member. The locking frame mounting member is, for example, a rail or a support rail. The frame body 301 is generally arranged further away from the locking frame mounting member relative to the frame mounting portion 302. The locking frame mounting member is generally located between the locking frame and a locking lever.

[0045] The frame body 301 can include two oppositely arranged extensions 3011 and a roller 3012 arranged at the lower end of the two extensions 3011.

[0046] In some embodiments, the heating element support plate 112 and the planar heating element 111 have substantially the same shape and size as the side surface of the extension 3011 opposite to the locking frame mounting member, so as to increase the heating area and the heating uniformity of the extension 3011 and improve the heating effect.

[0047] In some embodiments, the two locking frame heating elements 11 can be symmetrically arranged. The opposite side surfaces of the two heating element support plates 112 can be referred to as inner side surfaces, and the opposite side surfaces of the two extensions 3011 can also be referred to as inner side surfaces. The opposite side surfaces of the two heating element support plates 112 can be referred to as outer side surfaces, and the opposite side surfaces of the two extensions 3011 can also be referred to as outer side surfaces. The inner side surface of the heating element support plate 112 faces the direction close to the inner side surface of the other heating element support plate 112 and does not protrude from the corresponding inner side surface of the extension 3011, thereby avoiding interference with the locking lever 400.

[0048] In some embodiments, the planar heating element 111 can be a planar structure made of a flexible electric heating material, and the planar heating element 111 can generate and release heat outward after being electrified. Since the planar heating element 111 is a planar structure made of a flexible electric heating material, when the heating element support plate 112 and the extension 3011 of the frame body 301 are tightly mounted to the extension 3011 by the heating mounting member 113, the planar heating element 111 can be in close contact with the extension 3011 through slight deformation, thereby improving the heat conduction effect between the planar heating element 111 and the extension 3011 and reducing heat loss.

[0049] The planar heating element 111 can be fixedly arranged on the heating element support plate 112 by means of cementing or hot pressing, thereby facilitating installation, maintenance and replacement.

[0050] Referring to Figure 2 and Figure 3In some embodiments, the heating mounting 113 can include a top baffle 1131 and a bottom baffle 1132. The top baffle 1131 is connected with the upper end of the heating piece support plate 112 and extends along the top surface of the extension part 3011 toward the side where the frame mounting part 302 is located; the bottom baffle 1132 is connected with the lower end of the heating piece support plate 112 and extends along the bottom surface of the extension part 3011 toward the side where the frame mounting part 302 is located; and the top baffle 1131 and the bottom baffle 1132 respectively abut against the top surface and the bottom surface of the extension part 3011. In such embodiments, by abutting against the top surface and the bottom surface of the extension part 3011 through the top baffle 1131 and the bottom baffle 1132, the heating piece support plate 112 is prevented from moving up and down relative to the extension part 3011, and it is ensured that the planar heating piece 111 can abut against the extension part 3011 face to face.

[0051] Referring to Figure 2 and Figure 3 In some embodiments, the heating mounting 113 can further include a top connecting plate 1133 connected with the end of the top baffle 1131 away from the other locking frame heating piece 11 and extending upward, and the top connecting plate 1133 forms a through hole 11330; the heating connecting piece 12 passes through the through hole 11330 of the top connecting plate 1133 of the two locking frame heating pieces 11 to connect the two locking frame heating pieces 11. In such embodiments, since the top baffle 1131 and the bottom baffle 1132 respectively abut against the top surface and the bottom surface of the extension part 3011, the top connecting plate 1133 of the two locking frame heating pieces 11 is connected by the heating connecting piece 12, which is conducive to strengthening the abutting effect of the top baffle 1131 and the bottom baffle 1132 against the top surface and the bottom surface of the extension part 3011, and at the same time, it can also avoid interference with the locking frame 300 and affect the normal use of the locking frame 300.

[0052] Referring to Figure 2 , Figure 3 and Figure 11 , Figure 11 is Figure 1The figure shows a front view of the assembled locking frame heating assembly and the roller-type locking frame of the railway turnout external locking device. In some embodiments, the heating connector 12 may include a rod 120 with a thread on at least one end, at least one nut 121, and a sleeve 122. The rod 120 passes through a through-hole 11330 in the top connecting plates 1133 of the two locking frame heaters 11 and connects to the nut 121. The sleeve 122 is sleeved onto the rod 120 between the top connecting plates 1133 of the two locking frame heaters 11, limiting the minimum distance between the top connecting plates 1133 of the two locking frame heaters 11. In this embodiment, the sleeve 122 limits the minimum distance between the top connecting plates 1133 of the two locking frame heaters 11, preventing deformation of the heater support plate 112 due to overtightening of the rod 120 and nut 121, which could affect the thermal contact between the planar heater 111 and the extension 3011.

[0053] See also Figure 2 、 Figure 3 as well as Figure 11 In some embodiments, the top baffle 1131 forms an abutting portion 11310, which is used to abut against the top surface of the extension portion 3011. After the locking frame heating component 10 and the locking frame 300 are assembled, due to the existence of the processing gap, there is a gap in the height direction between the heating mounting member 113 of the locking frame heating component 10 and the extension portion 3011 of the locking frame 300 (that is, the sum of the gap between the top baffle 1131 and the top surface of the extension portion 3011, and the gap between the bottom baffle 1132 and the bottom surface of the extension portion 3011). If the rod 120 and the nut 121 are tightened too much, the distance between the two top connecting plates 1133 will be too close, which will cause the two top connecting plates to be locked. The ends of the top baffle 1131 that are separated from each other are tilted upward, affecting the abutment between the top baffle 1131 and the top surface of the extension portion 3011. The embodiment of the present application forms an abutment portion 11310, so that the abutment portion 11310 abuts against the top surface of the extension portion 3011, thereby eliminating the gap in the height direction and ensuring that the top baffle 1131 can abut against the top surface of the extension portion 3011, thereby making the installation of the locking frame heater 11 more stable and preventing the locking frame heater 11 and the locking frame 300 from having relative movement.

[0054] See also Figure 2 and Figure 3In some embodiments, the surface of the abutting portion 11310 facing away from the top baffle 1131 can be a slope, which extends downwardly and inclines away from the other locking frame heating element 11, so that the height of the abutting portion 11310 away from one end of the other locking frame heating element 11 is greater than the height of the abutting portion 11310 close to the other end of the other locking frame heating element 11, so that even when the end of the top baffle 1131 facing away is raised upwardly, the abutting portion 11310 can still abut against the top surface of the extending portion 3011, eliminating the installation instability caused by the machining gap.

[0055] Referring to Figure 2 and Figure 3 In some embodiments, the heating mounting member 113 can further include a side baffle 1134 and a side clamping member 1135. The side baffle 1134 is connected to the middle of the heating element support plate 112 away from the other locking frame heating element 11, and extends along the side surface of the extending portion 3011 (i.e. the outer side surface of the extending portion 3011) to the side where the frame mounting portion 302 is located; the side clamping member 1135 is connected to the side baffle 1134, and is used to clamp against the side surface of the extending portion 3011 facing away from the heating element support plate 112. In such embodiments, after the abutting installation of the heating element support plate 112 on the extending portion 3011, the above arrangement is conducive to preventing the relative movement of the locking frame heating element 11 and the extending portion 3011 in the width direction (i.e. the extending direction of the roller 3012) and the thickness direction (i.e. the direction perpendicular to the extending direction of the roller 3012 and the height direction of the heating element support plate 112), ensuring stable installation.

[0056] In some embodiments, the size of the side baffle 1134 in the height direction of the extending portion 3011 is greater than the size of the side clamping member 1135 in the height direction of the extending portion 3011, and the side baffle 1134 is a slope matched with the side surface of the extending portion 3011, so as to facilitate close contact with the side surface of the extending portion 3011. The side clamping member 1135 can be an L-shaped member.

[0057] Referring to Figure 2 and Figure 3 In some embodiments, the heating mounting member 113 can further include a bottom abutting member 1136 connected to the side of the bottom baffle 1132 close to the other locking frame heating element 11, and used to abut against the side surface of the extending portion 3011 opposite to the side baffle 1134 (i.e. the inner side surface of the extending portion 3011). In such embodiments, after the abutting installation of the heating element support plate 112 on the extending portion 3011, the above arrangement can further prevent the relative movement of the locking frame heating element 11 and the extending portion 3011 in the width direction, further ensuring stable installation.

[0058] In some embodiments, the length of the sleeve 122 is determined according to the distance between the two top connecting plates 1133 and the gap between each side baffle 1134 and the corresponding extension 3011 after the assembly of each lock frame heating element 11 and the extension 3011. It is easy to understand that the length of the sleeve 122 limits the minimum distance between the two top connecting plates 1133. The sleeve 122 determined in the above manner can avoid the deformation of the heating element support plate 112 caused by the over-tight installation of the rod 120 and the nut 121 when the rod 120 and the nut 121 are assembled.

[0059] Specifically, the assembly of the lock frame heating element 11 and the extension 3011 can be simulated by using three-dimensional software, and the distance between the two top connecting plates 1133 and the gap between each side baffle 1134 and the corresponding extension 3011 in the free state are measured, and the length of the sleeve 122 is determined by subtracting the gap between each side baffle 1134 and the corresponding extension 3011 from the distance between the two top connecting plates 1133 in the free state.

[0060] Referring to Figure 2 In some embodiments, each lock frame heating element 11 can further include an electrical connector 114 and a sealing material 115. The electrical connector 114 is used to electrically connect the power supply wire with the lead wire 1110 of the planar heating element 111, the top of the heating element support plate 112 forms a folded portion 1120, and the lead wire 1110 of the planar heating element 111 extends out of the folded portion 1120 to be connected with the electrical connector 114; and the sealing material 115 is filled at the folded portion 1120 to seal the lead wire 1110. In such embodiments, by providing the folded portion 1120 on the heating element support plate 112, the lead wire 1110 can be extended out of the lock frame heating element 11 to be connected with the electrical connector 114 without affecting the normal operation of the lock frame 300; and filling the sealing material 115 at the folded portion 1120 facilitates the filling operation of the sealing material 115, so that the sealing material 115 is firmly sealed and is not easy to fall off, and has good dustproof and waterproof effects on the outgoing portion of the lead wire 1110.

[0061] The sealing material 115 is, for example, a sealant.

[0062] The folded portion 1120 can be formed on the top of the heating element support plate 112 and close to another lock frame heating element 11, so as to neither affect the normal operation of the lock frame 300 nor affect the structural strength of the heating element support plate 112 itself.

[0063] In some embodiments, the folded portion 1120 can be formed by forming a U-shaped opening on the top of the heating element support plate 112, and folding the U-shaped plate in the U-shaped opening to form an included angle with the plane where the heating element support plate 112 is located.

[0064] In some embodiments, the opening of the folded portion 1120 faces upward to facilitate filling of the sealing material 115.

[0065] In some embodiments, the angle between the plane where the folded portion 1120 is located and the plane where the heating element support plate 112 is located is 20-30°, so that the folded portion 1120 avoids bending of the lead wire 1110 at the folded portion 1120 while not affecting the extension of the lead wire 1110, thereby protecting the lead wire 1110. For example, the angle between the plane where the folded portion 1120 is located and the plane where the heating element support plate 112 is located is 25°.

[0066] Referring to Figure 4 , Figure 4 is Figure 2 FIG. 13 is a structural schematic view of the electrical connector 114 of the locking frame heating element 11 shown in FIG. 1. In some embodiments, the electrical connector 114 can include a first connector 1141, a second connector 1142, a clamping member 1143, a clamping matching member 1144, and a protective sleeve 1145. The first connector 1141 is electrically connected to the lead wire 1110 of the planar heating element 111; the second connector 1142 is electrically connected to the power line; the first connector 1141 and the second connector 1142 are electrically connected by plugging; the clamping member 1143 and the clamping matching member 1144 are respectively arranged on the first connector 1141 and the second connector 1142 or respectively arranged on the second connector 1142 and the first connector 1141, and are used to clamp and match after the first connector 1141 and the second connector 1142 are plugged; and the protective sleeve 1145 is sleeved on the first connector 1141 and the second connector 1142 after the clamping member 1143 and the clamping matching member 1144 are clamped and matched. In such embodiments, after the first connector 1141 and the second connector 1142 are plugged, the clamping member 1143 and the clamping matching member 1144 are clamped and matched, which can prevent the first connector 1141 and the second connector 1142 from being unplugged; the first connector 1141 and the second connector 1142 are electrically connected by plugging, which is convenient for disassembly and maintenance; at the same time, by sleeving the protective sleeve 1145 on the first connector 1141 and the second connector 1142, the plug-in part of the first connector 1141 and the second connector 1142 can be protected, and the plug-in part of the first connector 1141 and the second connector 1142 can be waterproof, dustproof, and protected from natural erosion and aging; and by sleeving the protective sleeve 1145 on the first connector 1141 and the second connector 1142, it is beneficial to avoid accidental disconnection of the plug-in part of the first connector 1141 and the second connector 1142, and to ensure the stability of the plug-in part.
