[0028] Referring to Figure 1 and Figure 2 , an auxiliary device for internal welding repair operation of a coal hopper car provided by an exemplary embodiment of the present disclosure, the auxiliary device for internal welding repair operation of a coal hopper car includes:

[0029] A bracket assembly 1, including a base 11, a side ladder 13 hinged to the base 11, a fixed seat 12 fixed to the base 11, and a support hook 14 detachably connected to the fixed seat 12, the support hook 14 is also detachably connected to the side ladder 13, there are two side ladders 13 and they are distributed oppositely, and the side ladder 13 can only rotate from above the base 11 to a vertical posture;

[0030] A traveling assembly 3, including a downward pressing cross bar 31 hinged to the base 11, a universal wheel 32 fixed to the downward pressing cross bar 31, and a stop bar 33 fixed to the base 11, the downward pressing cross bar 31 has a first posture with the universal wheel 32 above the base 11 and above the stop bar 33, and has a second posture with the universal wheel 32 below the base 11 and below the stop bar 33;

[0031] A platform assembly 2, including a suspension ladder 21 for detachably connecting to two side ladders 13 at the same time, a partition 22 detachably connected to the suspension ladder 21 to form a storage platform, a pedal 23 movably connected to the side ladder 13, and a support member 24 fixed to the side ladder 13 for supporting the pedal 23 to maintain a horizontal posture.

[0032] Exemplarily, referring to Figure 1 and Figure 2 , the base 11 is a plate structure in a horizontal posture, there are two side ladders 13, the two side ladders 13 are respectively hinged to both ends of the base 11, a limit hinge member 5 is fixed to the end of the base 11, there are two limit hinge members 5 at the same end of the base 11, and the two limit hinge members 5 on the same end of the base 11 are arranged on both sides of the base 11. The top end of the limit hinge member 5 extends above the top surface of the base 11, the bottom end of the side ladder 13 extends into the top end of the limit hinge member 5 and is hinged to the limit hinge member 5 through a shaft body, the rotation axis of the side ladder 13 is horizontally arranged, and the limit hinge member 5 limits the position of the side ladder 13, so that the side ladder 13 can only rotate axially at the end of the base 11, and the side ladder 13 can rotate from a horizontal position and against the base 11 to a vertical posture.

[0033] The limit hinge 5 is a plate structure composed of two plates fixed vertically on the top surface of the base 11 and spaced apart. The bottom end of the side ladder 13 extends between these two plate structures and is fixed by a shaft body to achieve rotation. On the side of the limit hinge 5 facing away from the base 11, there is a blocking portion 51 for preventing the side ladder 13 from rotating outward to the outside of the base 11. The blocking portion 51 is located above the end face of the base 11 and transversely blocks the channel between the two plate structures mentioned above. That is, the limit hinge 5 with the blocking portion 51 fixed only allows the side ladder 13 to rotate from the vertical posture to the horizontal posture in the direction of the other side ladder 13. The blocking portion 51 limits the maximum rotatable angle of the side ladder 13 and provides a certain supporting effect for the side ladder 13 in the vertical posture.

[0034] The fixed seat 12 is a frame structure fixed on the top surface of the base 11 and is located at the central position of the top surface of the base 11. The fixed seat 12 has a first socket 121 for accommodating the support hook 14. The first socket 121 includes a counterbore opened at the edge of the top surface of the fixed seat 12, and the counterbore extends vertically downward inside the solid structure of the fixed seat 12. The side ladder 13 has a second socket 131 for accommodating the support hook 14. The second socket 131 includes a sleeve fixedly connected to the side wall of the side ladder 13. The axis of the sleeve in the vertical posture is vertically arranged, and at this time, the sleeves on the two side ladders 13 are respectively fixed on the opposite side walls of the two side ladders 13. The support hook 14 is a rod structure with both ends bent in the same direction. By inserting the two ends of the support hook 14 into the first socket 121 and the second socket 131 respectively, the support hook 14 can be fixed between the side ladder 13 and the fixed seat 12. The side ladder 13 is supported by the support hook 14. Combining with the connection function of the limit hinge 5 and the blocking portion 51 to the side ladder 13, the side ladder 13 can maintain its current posture. By replacing the support hooks 14 with different lengths, different angles of the side ladder 13 can also be adapted.

[0035] Refer to Figure 1 and Figure 3, a pin shaft 4 is fixed on the base 11. The pin shaft 4 is horizontally arranged and parallel to the rotation axis of the side ladder 13. One end of the pin shaft 4 is fixedly connected to the side wall of the base 11, and the other end extends in a direction away from the base 11. One end of the downward pressing cross bar 31 is fixedly connected with a horizontally arranged sleeve 311. The sleeve 311 is arranged perpendicular to the downward pressing cross bar 31 and sleeved on the pin shaft 4, so as to realize the rotation of the downward pressing cross bar 31 around the pin shaft 4. The stop bar 33 is horizontally arranged and parallel to the rotation axis of the side ladder 13. One end of the stop bar 33 is fixed on the end face of the base 11, and the other end extends outward from the side wall of the base 11 along the length direction of the pin shaft 4. The pin shaft 4 and the stop bar 33 acting on the same downward pressing cross bar 31 are distributed relatively. There is a positioning groove 331 for clamping the downward pressing cross bar 31 below the stop bar 33. By disassembling the sleeve 311 from the pin shaft 4, rotating the downward pressing cross bar 31 and then reinstalling the sleeve 311, the position change of the downward pressing cross bar 31 above and below the stop bar 33 can be realized. When the downward pressing cross bar 31 is located below the stop bar 33, the downward pressing cross bar 31 is placed inside the positioning groove 331. The stop bar 33 provides both vertical and horizontal limits for the downward pressing cross bar 31. At this time, the downward pressing cross bar 31 is in a horizontal posture, and the universal wheel 32 is exposed from below the base 11. When the downward pressing cross bar 31 is located above the stop bar 33, by rotating the downward pressing cross bar 31, the universal wheel 32 can be stopped above the bottom surface of the base 11, so that the base 11 can be stably placed on the ground.

[0036] The suspension ladder 21 is horizontally arranged. Four connecting rods 213 are fixed on the bottom surface of the suspension ladder 21. The four connecting rods 213 extend vertically downward and are distributed at the four sharp corner positions of a rectangle. The end of the side ladder 13 away from its hinge end is recessed inward to form a sinking groove 133 for accommodating the connecting rod 213. After the side ladder 13 rotates to the vertical posture, the suspension ladder 21 is installed by inserting the connecting rod 213 into the sinking groove 133. Similarly to using support hooks 14 with different lengths to adapt to side ladders 13 at different angles, by using suspension ladders 21 with different lengths, or suspension ladders 21 with different distances between the connecting rods 213, side ladders 13 at different angles can be adapted. Referring additionally to Figure 4 , in order to meet the requirements of different working conditions, one end of the suspension ladder 21 has a suspension hook 212 bent into a hook shape, and the bending direction of the suspension hook 212 is opposite to the extending direction of the connecting rod 213.

[0037] A plurality of footrests 211 are fixed on the suspension ladder 21. The footrests 211 are horizontally arranged and perpendicular to the suspension ladder 21. The footrests 211 are spaced along the length direction of the suspension ladder 21. The partition plate 22 is horizontally placed on the suspension ladder 21. The end of the partition plate 22 has a fixing part 221 bent downward for lapping the footrest 211. Both ends of the partition plate 22 have fixing parts 221, so as to provide horizontal limits for the partition plate 22. The fixing part 221 can also be buckled on the footrest 211 to limit the position of the partition plate 22 through the fixing part 221.

[0038] Similar to the hanging ladder 21, a plurality of climbing frames 132 are fixed on the side ladder 13. The climbing frames 132 are in a horizontal posture and perpendicular to the side ladder 13, and the climbing frames 132 are spaced along the length direction of the side ladder 13. Taking the side ladder 13 in a vertical posture as an example for explanation: One end of the pedal 23 is sleeved on the climbing frame 132 with the highest horizontal position, and the other end naturally hangs down under the action of gravity; The support member 24 is a plate-like structure formed by bending both ends to the same side to form a gull-wing structure. Both ends of the support member 24 are fixed to both sides of the side ladder 13 respectively, forming a posture of straddling the top of the side ladder 13. A passage for people to pass through is formed between the support member 24 in a bent posture and the side ladder 13. By rotating the pedal 23, the pedal 23 can be rotated to the top of the support member 24 and abut against the support member 24 when the pedal 23 is in a horizontal posture, and the support member 24 supports the pedal 23 in a horizontal posture.

[0039] In this embodiment, the base 11 is used as a bearing foundation, the side ladder 13 supports the hanging ladder 21, the fixing seat 12 and the support hook 14 fix the side ladder 13 in an upright posture, the partition plate 22 provides a platform for placing objects, and the pedal 23 provides a standing platform for welding operations. By removing the support hook 14, the side ladder 13 is rotated to reduce the vertical height, the downward pressing cross bar 31 is moved below the stop bar 33, and the removed hanging ladder 21 is placed above the base 11, so that the base 11 can move under the action of the universal wheels 32.
