[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments, highlighting the above and other technical features and advantages of the present invention. However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.

[0022] Example:

[0023] like Figures 1-4 As shown, this utility model provides a comb plate for fixing the reinforcing steel bars of the overhead contact line platform of a railway box girder. It includes a comb tooth fixing plate 1, a number of comb tooth components 2 are provided at the bottom of the comb tooth fixing plate 1, and the number of comb tooth components 2 respectively play the role of fixing different groups of reinforcing steel bars. A horizontal component 3 is provided at the top of the comb tooth fixing plate 1. The horizontal component 3 is used to observe the setting state of the comb tooth fixing plate 1. An external connection fixing component 4 is provided at the back of the comb tooth fixing plate 1. The external connection fixing component 4 is used to connect with an external platform and provide support for the comb tooth fixing plate 1.

[0024] The comb tooth fixing plate 1 includes a fixing plate body 11, a comb tooth assembly mounting groove 12, a fixing screw hole 13, and a connecting screw hole 14;

[0025] The comb assembly mounting groove 12 is located at the bottom of the fixing plate body 11, the fixing screw holes 13 are located at both ends of the comb assembly mounting groove 12 and penetrate through the fixing plate body 11, and the connecting screw holes 14 are located at the middle of both ends of the fixing plate body 11. The comb fixing plate 1 is connected to the external connecting fixing component 4 through the connecting screw holes 14, and the comb fixing plate 1 is connected to the comb assembly 2 through the comb assembly mounting groove 12.

[0026] The comb assembly 2 includes comb teeth 21 and fixing screws 22;

[0027] Several sets of comb teeth 21 are arranged side by side inside the comb tooth assembly mounting groove 12. The middle of the comb teeth 21 is provided with a through hole of the same specification as the fixing screw hole 13. The fixing screw 22 passes through the fixing screw hole 13 and is threadedly connected to the comb teeth 21. The comb teeth 21 are provided with several sets of different specifications. The specifications of the several sets of comb teeth 21 increase in sequence according to the fixed width. The surface of the comb teeth 21 is engraved with numerical scales. Different specifications of comb teeth 21 can be selected and combined according to different construction needs to better adapt to different construction needs. When the steel bar is inserted into the comb teeth 21, the numerical scales on the surface of the comb teeth 21 can be used to mark the setting height of different steel bars to facilitate the adjustment of the setting height of the steel bars.

[0028] An anti-slip pad 221 is provided at the end of the fixing screw 22. The anti-slip pad 221 is made of rubber. When the through hole at the center of the comb tooth 21 is not aligned with the fixing screw 22, the fixing screw 22 can make the anti-slip pad 221 abut against the comb tooth 21 through the threaded connection. This limits the setting position of the comb tooth 21 by friction fixation, thereby improving the adaptability of the setting method of the comb tooth 21.

[0029] The leveling component 3 includes a disc level 31 and a horizontal level tube 32;

[0030] Two sets of disc levels 31 are respectively set on the top two sides of the disc level 31, and a horizontal level tube 32 is placed horizontally between the two sets of disc levels 31. The disc level 31 can be used to observe the horizontal state of the comb tooth fixing plate 1, and the horizontal level tube 32 is used to assist in the initial adjustment of the comb tooth fixing plate 1. When adjusting the position of the comb tooth fixing plate 1, first observe the setting position of the horizontal level tube 32 and adjust it, and then observe the disc level 31 to make a second adjustment to the position of the comb tooth fixing plate 1.

[0031] The external connection fixing assembly 4 includes a connecting tube 41, a magnetic suction part 42, and a connecting screw 43;

[0032] The magnetic suction part 42 is fixed to the end of the connecting tube 41. The connecting tube 41 is connected to the external platform by magnetic attraction. The connecting screw 43 passes through the connecting screw hole 14 and is threaded to the magnetic suction part 42. During the initial installation, the magnetic suction part 42 is connected to the external platform by magnetic attraction. The connecting tube 41 is fixed under the support of the magnetic suction part 42. At this time, the connecting screw 43 can fix the comb tooth fixing plate 1 to the end of the connecting tube 41 by threaded connection. At this time, the external connecting fixing component 4 plays a supporting role for the comb tooth fixing plate 1.

[0033] A sleeve hole 421 is provided at the center of the magnetic suction part 42. The sleeve hole 421 is used to connect with an external vertical rod. When there is no adsorption and fixing condition, a vertical rod can be set on the surface of the external platform, and the sleeve hole 421 can be connected with the external vertical rod. The vertical rod provides a fixing point for the magnetic suction part 42 through the cooperation with the sleeve hole 421. At the same time, the setting position of the magnetic suction part 42 can be initially fixed by magnetic attraction.

[0034] This is merely a preferred embodiment of the present invention and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of this invention, all of which will fall within the protection scope of this invention.
