Description

Technical Field

[0001] This utility model belongs to the technical field of heating devices, specifically relating to a heating device for a turnout locking frame. Background Technology

[0002] The turnout is an important branch point for trains entering the station. Whether the turnout is properly moved (the degree of closeness between the turnout tip or core and the stock rail) directly affects the safety of train operation. In winter, due to snow or ice between the turnout tip or core and the stock rail, the connection is not close enough. Therefore, it is necessary to install a heating device on the lower surface of the turnout locking frame side edge to heat and prevent snow accumulation and icing. The existing heating device is a heating element installed on the lower surface of the turnout locking frame side edge to heat and prevent snow accumulation and icing.

[0003] The existing turnout locking frame is an important component of the turnout switching machine. Preventing snow or ice accumulation in this area is one of the key factors affecting the normal operation of the switching machine. Currently, the heating device for the turnout locking frame in China is basically mature. The CN series turnout locking frame is an imported turnout, and its special structure means that the heating device cannot be installed on the existing domestic turnout locking frame. This prevents the installation of heating strips, causing snow or ice to get stuck between the turnout tip or core and the stock rail, resulting in poor contact and safety issues. It also affects the convenience of installing the heating device on the turnout locking frame. Therefore, this utility model proposes a turnout locking frame heating device. Utility Model Content

[0026] To facilitate the tight fit and heating of the main heating strip 101 and the side edge of the locking frame using the snap-fit ​​mounting assembly, in this embodiment, preferably, the snap-fit ​​mounting assembly includes clamps 1012 disposed at both ends of the main heating strip 101. An aluminum pad 1011 is disposed at the connection between the bottom end of the clamp 1012 and the upper surface of the main heating strip 101. The upper surface of the main heating strip 101 is in close contact with the surface of the aluminum pad 1011, and the lower surface of the main heating strip 101 is in close contact with the inner surface of the clamp 1012. After the aluminum pad 1011 is tightly fitted to the main heating strip 101, the ends of the main heating strip 101 and the aluminum pad 1011 are reinforced and installed by the two clamps 1012, which facilitates the reinforced installation and use.

[0027] In order to facilitate the reinforcement and installation of the clamp 1012 by means of the limiting and reinforcing component, in this embodiment, preferably, the limiting and reinforcing component includes a limiting top plate 1019 integrally disposed at one end of the clamp 1012, and an anti-detachment hook 1018 integrally disposed on the inner side of the other end of the clamp 1012. When the clamp 1012 is engaged with the side edge of the locking frame, the limiting top plate 1019 and the anti-detachment hook 1018 are used to strengthen and fix the installation, which facilitates the reinforcement and use.

[0028] To facilitate the installation of the end of the main heating strip 101 using the closed mounting assembly and to make it easy to fix and use, in this embodiment, preferably, the closed mounting assembly includes a heating strip fork handle 1013 disposed at the connection between the end of the main heating strip 101 and the end of the cable 102. The end of the main heating strip 101 and the inside of the heating strip fork handle 1013 are clamped and installed by means of a clamp and screws. The end of the heating strip fork handle 1013 is fixedly mounted with a mounting frame 1015 by bolts. After the end of the main heating strip 101 is installed inside the heating strip fork handle 1013, the heating strip fork handle 1013 can be installed again by means of the mounting frame 1015.

[0029] To facilitate the adjustment of the mounting frame 1015 after the installation of the fixed hook 1017 using the reinforced hook assembly, so that the heating bar fork core handle 1013 is installed in a certain position, in this embodiment, preferably, the reinforced hook assembly includes a fixed hook 1017 disposed at the end of the mounting frame 1015. A reinforcing threaded rod 1016 passes through the connection between the end of the fixed hook 1017 and the mounting frame 1015. A reinforcing nut 1014 is threadedly connected to the outer surface of the reinforcing threaded rod 1016 at the end surfaces of the mounting frame 1015 and the fixed hook 1017. The fixed hook 1017 and the mounting frame 1015 can be fixed together by the reinforcing threaded rod 1016 and the reinforcing nut 1014, thereby fixing the heating bar fork core handle 1013 in the corresponding position.

[0030] The reinforcement and stabilization mechanism includes a limiting and locking component disposed at the end of the reinforcement hook assembly. The limiting and locking component contains the reinforcement and stabilization component, which can engage and install the fixed hook 1017 during installation. The reinforcement and stabilization mechanism strengthens and fixes the end of the fixed hook 1017 to the track, thereby stabilizing and reinforcing it for heating.

[0031] In order to facilitate the locking and securing of the fixed hook 1017 by means of the limiting and locking assembly, and to reinforce the locking and securing by the thickened hook plate 103 during the installation, in this embodiment, preferably, the limiting and locking assembly includes a thickened hook plate 103 integrally disposed at the end of the fixed hook 1017. The thickened hook plate 103 has a limiting groove 1034 inside, and the fixed hook 1017 is locked, installed and secured by the thickened hook plate 103.

[0032] To facilitate reinforcing the installation of the fixed hook 1017 after it has been engaged with the thickened hook plate 103 at the end, in this embodiment, the reinforced and stabilizing component preferably includes a limiting moving tooth plate 1033 installed inside the limiting groove 1034. The surface of the thickened hook plate 103 is threadedly connected to a threaded post 1031. The end of the threaded post 1031 is mounted to the interior of the limiting moving tooth plate 1033 via a bearing. A fixed tooth plate 1032 is integrally provided at a position symmetrical to the end of the thickened hook plate 103 and the limiting moving tooth plate 1033. When the fixed hook 1017 is engaged, the end of the fixed hook 1017 is reinforced and engaged by the thickened hook plate 103, and the threaded post 1031 is rotated to cause the limiting moving tooth plate 1033 to press against the surface of the track. The fixed tooth plate 1032 on the other side contacts the other side of the track surface, thereby facilitating the reinforcing installation.

[0033] The working principle and usage process of this utility model are as follows: When using this turnout locking frame heating device, first clean the debris at the installation location to avoid affecting the installation. After cleaning, when installing, close the aluminum pad 1011 on the end surface of the main heating strip 101. Then, install the clamp 1012 at the end of the aluminum pad 1011 and the main heating strip 101. The clamp 1012 is used to engage the aluminum pad 1011 and the main heating strip 101 on the front surface of the locking frame side edge. When engaged, the top of the clamp 1012 is limited to the top of the locking frame side edge by the limiting top plate 1019. The anti-detachment hook 1018 is engaged in the corresponding slot on the side of the locking frame side edge, thereby reinforcing the main heating strip 101 and the aluminum pad 1011 with the locking frame side edge through the two clamps 1012.

[0034] The fixing hook 1017 is then engaged again at the corresponding installation location on the track. The engagement of the fixing hook 1017 does not affect the normal operation of the track. After the fixing hook 1017 is installed, the heating strip turnout core handle clip 1013 is positioned in the installation location by adjusting the mounting frame 1015 through the reinforcing threaded rod 1016 and the reinforcing nut 1014 at the end of the fixing hook 1017. After adjustment, the reinforcing nut 1014 is rotated again to reinforce it, thus securing the heating strip turnout core handle clip 1013 in the installation location. This facilitates the fixed installation of the main heating strip 101, making it convenient for heating and use. After the main heating strip 101 is installed, the cable 102 is connected to a power source to energize and heat the main heating strip 101. When the main heating strip 101 is heated, it heats the turnout locking frame, preventing snow accumulation and icing from causing danger, thereby improving the convenience of installing the main heating strip 101 on the turnout locking frame.

[0035] Finally, after the fixed hook 1017 is engaged with the corresponding installation position on the track, the fixed tooth plate 1032 is brought into contact with the upper surface of one side of the track again, the thickened hook plate 103 is engaged with the bottom end of one side of the track, and the threaded column 1031 is rotated to drive the limiting moving tooth plate 1033 to move within the limiting groove 1034 until the limiting moving tooth plate 1033 is moved and pressed tightly against the lower surface of one side of the track. This makes it easy to reinforce the fixed hook 1017 after it is engaged and installed, and it is not easy to loosen when subjected to force after installation. The reinforced installation improves the reinforcement and fixation of the fixed hook 1017 by the heating device body 100 during installation and use.

[0036] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
