A walking trolley for rapid construction of culverts according to claim 8, characterized in that one end of the sliding rod (81) passes through the sliding sleeve (8), and the sliding rod (81) passes through the first Four springs (82) are connected with the sliding sleeve (8); the sliding sleeve (8) is fixedly connected with a fixed block, and the frame body (1) is arranged on the fixed block and the limit ball (83) between; the slide bar (81) includes a limiting portion (85), and the grooves (84) are arranged on both sides of the limiting portion (85), when the limiting ball (83) and the limiting portion ( 85) when in contact, one end of the limit ball (83) is located outside the sliding sleeve (8). 10. A method for using a walking trolley for rapid construction of a culvert, characterized in that, using the walking trolley for rapid construction of a culvert according to claim 9 comprises the following steps: When the width of the frame (1) needs to be increased: Select the connecting frame (2) of the specified size, and move one end of the connecting block (7) into the slot (21) by moving the connecting frame (2). With the movement of the connecting block (7), the tapered sleeve ( Under the action of 72), the block (62) is driven to move inward, and the first spring (61) is compressed, so that the tapered sleeve (72) moves between the block (62) and the slide plate (6). The sliding plate (6) is in contact with the connecting block (7), so that the first spring (61) is in a compressed state, and after the tapered sleeve (72) contacts the block (62), the adjacent connecting frame (2) connection work, so as to realize the increase of the width of the frame body (1); When the width of the frame body (1) needs to be reduced: By moving the connecting frame (2), the connecting block (7) continues to move into the slot (21), so that the first spring (61) is further compressed, and under the action of the tapered block (75), the block ( 62) Move inward to compress the first spring (61), move the tapered block (75) between the tapered sleeve (72) and the block (62), and move the connecting frame (2) outward to make The tapered block (75) is engaged in the tapered sleeve (72), so that the third spring (73) is compressed, and the tapered block (75) drives the tapered sleeve (72) to move out of the slot (21), thereby realizing The disassembly work of the adjacent connecting frame (2), thereby completing the reduction of the width of the frame body (1); When the frame body (1) and the connecting frame (2) need to be connected: By moving the connecting frame (2), the through hole of the connecting frame (2) is moved to the limit hole (12) side of the frame body (1), and the sliding sleeve (8) is inserted into the through hole and the limit hole (12). ), as the slide rod (81) is pressed, the limit ball (83) moves into the groove (84), so that the sliding sleeve (8) penetrates the through hole and the limit hole (12), and the fourth spring Drive the slide bar (81) to move under the action of (82), so that the limit ball (83) moves to the outside of the sliding sleeve (8), and the fixed block and the limit ball (83) cooperate with each other to realize the connection between the frame body (1) and The connection of frame (2); Start the first oil cylinder (32) and the second oil cylinder (42), the first oil cylinder (32) drives the outer formwork (3) to rotate through the first parallelogram support, and the second oil cylinder (42) drives the inner formwork through the second parallelogram support (4) Rotate, the outer formwork (3) and the inner formwork (4) cooperate with each other, thereby complete the pouring work of the body of wall (51).
