[0030] It should be noted that the two wall panels to be pressed by the open car 3 refer to the inner wall panel 31 and the outer wall panel 32 that have just been overlapped (combined with reference to Figure 2 ), but due to the uneven surfaces of the inner wall panel 31 and the outer wall panel 32, there is a gap between the two in the left and right directions.

[0031] In this embodiment, the assembly device for repairing the side wall of the open car 3 is composed of a mobile flat car 1, a connecting frame 2, abutment members and a pushing member. When it is necessary to press the two wall panels to be pressed on the open car 3, the mobile flat car 1 can be placed on the upper eaves beam of the open car 3, and the first connecting arm 21 of the connecting frame 2 is extended to the inside of the open car 3, and the second connecting arm 22 of the connecting frame 2 is extended to the outside of the open car 3. The mobile flat car 1 can move along the upper eaves beam to drive the connecting frame 2 to reach the vicinity of the two wall panels to be pressed; the abutment members can be installed to move up and down The push piece is mounted on the first connecting arm 21, and can reach the height of the inner wall panel 31 to be pressed by moving up and down. At this time, the push piece can be driven manually to abut the inner wall panel 31; the push piece can be mounted on the second connecting arm 22 and can reach the height of the outer wall panel 32 to be pressed by moving up and down. At this time, the push piece can be driven electrically to push the outer wall panel 32, so that the outer wall panel 32 is deformed inwards, so as to press the outer wall panel 32 against the inner wall panel 31. Thus, the pressing work of the two wall panels is realized to eliminate the gap between the two wall panels, facilitate the formation of the weld at the overlap of the two wall panels, and ensure the welding quality.

[0032] Optionally, see Figure 3 and Figure 4 The first connecting arm 21 is provided with a first elongated hole extending up and down, and a movable seat 211 which can slide up and down is installed in the first elongated hole, and the abutment member is arranged on the movable seat 211; the second connecting arm 22 is provided with a second elongated hole 221 extending up and down, and the pushing member is passed through the second elongated hole 221 and can move up and down relative to the second elongated hole 221.

[0033] For details, please refer to Figure 3 A limiting plate 2111 is provided on the movable seat 211. When the abutting member abuts against the inner wall plate 31, the limiting plate 2111 is used to press against the side of the first connecting arm 21 close to the second connecting arm 22 to limit the abutting member from being separated from the first elongated hole.

[0034] In this embodiment, the movable seat 211 can slide up and down in the first elongated hole, thereby driving the abutment member to move up and down. The movable seat 211 and the first elongated hole have reliable structures, which can ensure the smooth movement of the abutment member. The pushing member is passed through the second elongated hole 221 and can move up and down, that is, the pushing member can be installed on the second connecting arm 22 to move up and down, which has a simple structure and is easy to install.

[0035] Optionally, see Figure 1 The mobile flat car 1 is provided with an electric hoist 4, and a first steel wire rope 41 and a second steel wire rope 42 are wound around the electric hoist 4. The free end of the first steel wire rope 41 is connected to the abutment member, and the free end of the second steel wire rope 42 is connected to the pushing member.

[0036] In this embodiment, the combination of the electric hoist 4, the first steel wire rope 41 and the second steel wire rope 42 can drive the abutment and the pushing member to move up and down. Specifically, when the electric hoist 4 retracts the first steel wire rope 41, the first steel wire rope 41 can immediately lift the abutment and move it upward; when the electric hoist 4 releases the first steel wire rope 41, the abutment can immediately move downward under its own weight; when the electric hoist 4 retracts the second steel wire rope 42, the second steel wire rope 42 can immediately lift the pushing member and move it upward; when the electric hoist 4 releases the second steel wire rope 42, the pushing member can immediately move downward under its own weight. The electric hoist 4 has a stable lifting capacity, which can ensure the safe lifting and lowering of the abutment and the pushing member.

[0037] Optionally, see Figure 1 The movable flat car 1 is provided with a first pulley 5 and a second pulley 6 , the first steel wire rope 41 passes around the first pulley 5 , and the second steel wire rope 42 passes around the second pulley 6 .

[0039] Optionally, see Figure 3 The abutment member includes a screw rod 7 threadedly connected to the movable seat 211.

[0040] For details, please refer to Figure 3 A horizontally extending through hole is provided in the movable seat 211, and the hole wall of the through hole is formed with an internal thread. The peripheral wall of the screw rod 7 is formed with an external thread matching the internal thread. The external thread and the internal thread match to realize the threaded connection between the movable seat 211 and the screw rod 7.

[0041] In this embodiment, the screw rod 7 is threadedly connected to the movable seat 211. When the screw rod 7 is screwed in the direction of the inner wall panel 31, the end of the screw rod 7 abuts against the inner wall panel 31. The tightening force of the screw rod 7 is reliable to stably abut against the inner wall panel 31.

[0042] Optionally, see Figure 3 An operating wheel 71 is provided at one end of the screw rod 7 away from the second connecting arm 22 .

[0043] In this embodiment, an operating wheel 71 is provided to facilitate operation by personnel to rotate the screw rod 7 in or out.

[0044] Optionally, see Figure 3 , the pushing member includes a hydraulic cylinder 8.

[0045] In this embodiment, the hydraulic cylinder 8 is used as a pushing member. The hydraulic cylinder 8 has a large pushing force, which can ensure the inward deformation of the outer wall panel 32, so that the outer wall panel 32 and the inner wall panel 31 are tightly attached, effectively eliminating the gap between the outer wall panel 32 and the inner wall panel 31.

[0046] Optionally, see Figure 3 A limiting ring rib 81 is formed on the circumferential side of the cylinder body of the hydraulic cylinder 8 , and the limiting ring rib 81 is used to press against the side of the second connecting arm 22 close to the first connecting arm 21 when the hydraulic cylinder 8 pushes the outer wall panel 32 .

[0047] In this embodiment, by providing a limiting ring rib 81, when the hydraulic cylinder 8 pushes the outer wall panel 32, the limiting ring rib 81 is pressed against the first connecting arm 21. This pressing action in turn has a limiting effect on the hydraulic cylinder 8, so that the hydraulic cylinder 8 can stably push the outer wall panel 32 and ensure the pressing effect between the outer wall panel 32 and the inner wall panel 31.

[0048] Optionally, see Figure 1 Note that the connecting frame 2, the abutment member and the pushing member are clamping mechanisms. Two clamping mechanisms are arranged, and the two clamping mechanisms are respectively arranged on the lower sides of the two ends of the mobile flat car 1. With this arrangement, the two clamping mechanisms can respectively and simultaneously clamp the wall panels on the left and right sides of the open car 3, thereby improving the clamping efficiency.

The wheels 13 are used to roll on the upper eaves beam so that the mobile flat car 1 moves along the upper eaves beam.

[0050] In this embodiment, the movement of the mobile flat car 1 along the upper eaves beam can be achieved through the axle 12 and the wheel 13 to avoid placing the assembly device for repairing the side wall of the open car 3 on the ground near the open car 3, thereby reducing the occupation of the ground near the open car 3.

[0051] Optionally, see Figure 5 and Figure 6 The mobile flat car 1 also includes a motor 14, a first sprocket 15, a second sprocket 16 and a chain 17. The motor 14 is installed on the frame 11, the first sprocket 15 is arranged on the output shaft of the motor 14, the second sprocket 16 is arranged on the axle 12, and the chain 17 is wound around the first sprocket 15 and the second sprocket 16.

[0052] In this embodiment, through the motor 14, the first sprocket 15, the second sprocket 16 and the chain 17, when the motor 14 is working, the second sprocket 16 can be driven to rotate through the first sprocket 15 and the chain 17, thereby driving the axle 12 to rotate, and then driving the wheel 13 to rotate, realizing the walking movement of the mobile flat car 1, and the sprocket chain 17 transmission method has a compact structure, which is conducive to reducing the volume of the device.
