The invention discloses a connecting rod leg-imitated type travelling mechanism and method. The connecting rod leg-imitated type travelling mechanism comprises a main body, shafts and connecting rod mechanisms. The connecting rod mechanisms are connected with the shafts through crankshafts and symmetrically distributed on the two sides of the main body. Each connecting rod mechanism on each side comprises a forefoot connecting rod mechanism body and a hindfoot connecting rod mechanism body. The shafts comprise the front shafts and the rear shafts. One end of each crankshaft and the corresponding front shaft are in rotation pair constraint, and the other end of the crankshaft is connected with a corresponding short forefoot connecting rod and a corresponding long hindfoot connecting rod so that the short forefoot connecting rod and the long hindfoot connecting rod can be driven to rotate. The short forefoot connecting rod and a corresponding long forefoot connecting rod are in rotation pair constraint. Each long forefoot connecting rod and the corresponding rear shaft are in rotation pair constraint. The method comprises the following steps that the crankshafts drive the short forefoot connecting rods to start moving, and then other connecting rods are driven to move in sequence, so that the whole travelling mechanism moves forwards. The travelling mechanism is simple in structure, traveling can be completed through the simple crankshaft-connecting rod structure, and the connecting rod mechanisms have the characteristics of being capable of bearing large loads, convenient to manufacture and capable of reducing production cost and later maintenance cost.

The invention relates to a covering device for a bridge expansion joint. The covering device for the bridge expansion joint is used for covering a pavement part of the bridge expansion joint, and comprises a rubber body (9) flush with the horizontal height of the bridge pavement, a support body (8) located inside the rubber body (9), and two extending support pieces (7) capable of moving face to face and reversely and having mutually symmetrical structures in the support body (8), wherein each of the extending support pieces (7) comprises a horizontal extending head part (721) capable of horizontally sliding in a sliding chute (81) of the support body (8), a vertical extending part (72) connected with the horizontal extending head part (721), and a support arm (71) connected with the lower end of the vertical extending part (72) and extending toward an adjacent bridge structure body; support plates (73) abutted with the adjacent bridge structure body are respectively arranged on end parts of the two extending support pieces (7).

The invention provides service life prolonged bridge expansion joint covering equipment which is used for covering the road surface at a bridge expansion joint. The bridge expansion joint covering equipment comprises a rubber body (9) flush with the horizontal height of the bridge road surface, a supporting body (8) located in the rubber body (9) and two extending and supporting parts (7) capable of moving towards each other or away from each other in the supporting body (8) and symmetric in structure, wherein each of the two extending and supporting parts (7) comprises a horizontal extension head part (721) capable of horizontally sliding in a sliding groove (81) of the supporting body (8), a vertical extension part (72) connected with the horizontal extension head part (721) and a supporting arm (71) connected with the lower end of the vertical extension part (72) and extending towards an adjacent bridge structure body; and the ends of the two extending and supporting parts (7) are each provided with a supporting plate (73) used for abutting against the adjacent bridge structure body.

The invention discloses an expansion joint covering device for a municipal bridge, which is used for covering a road surface of a bridge expansion joint. The expansion joint covering device for the municipal bridge comprises a rubber body (9) which is flush with the horizontal level of a bridge road surface, a supporting body (8) which is positioned in the rubber body (9), and two extending supporting pieces (7) which can move in directions facing each other and opposite to each other in the supporting body (8) and are mutually symmetrical in structures, wherein each of the two extending supporting pieces (7) comprises a horizontal extending head part (721) which can horizontally slide in a sliding chute (81) of the supporting body (8), a vertical extending part (72) which is connected with the horizontal extending head part (721), and a supporting arm (71) which is connected with the lower end of the vertical extending part (72) and extends towards an adjacent bridge structure body, wherein a supporting disc (73) which is used for being connected with the adjacent bridge structure body in a propping manner is arranged at the end part of each of the two extending supporting pieces (7).
