Detailed Description

The utility model is further illustrated with reference to the following figures and examples.

As shown in fig. 1 to 4, a mobile operation trolley capable of lifting materials comprises a rectangular chassis frame 1, rollers 2 respectively mounted at the bottoms of four corners of the chassis frame, upright posts 3 mounted at four corners of the chassis frame, a cross beam 4 mounted at the tops of the four upright posts and enclosing into a rectangle, an operation platform 5 mounted on the cross beam, and fences 6 mounted around the operation platform. Two parallel obliquely climbing rails 7 are arranged on the outer sides of two stand columns positioned on the same side, the top ends of the rails extend to an operation platform, an upper material rack 8 capable of climbing and descending along the rails is arranged on the rails, a lower pulley 9 is arranged on a chassis frame and close to the side of the rails, an upper pulley 10 is correspondingly arranged on a cross beam above the lower pulley, a winch 11 is arranged on the chassis frame and far away from the side of the rails, a winch steel rope 12 sequentially bypasses the lower pulley and the upper pulley and then is connected with the upper material rack, steel wheels capable of advancing along the rails are arranged at the bottom of the upper material rack, the upper material rack can climb along the rails under the driving of the winch, materials required by construction are conveyed to the operation platform, and labor and time are saved. The design of this embodiment is that double track way single hoist engine material loading mode also can set up double track way double hoist engine mode, sets up two sets of hoist systems that are parallel, connects the both ends of material loading frame with two parallel wire rope, makes the material loading frame climb more steadily. And a vertical ladder 13 with a protective cage 14, which is lifted from the chassis frame to the operation platform, is arranged on the outer sides of the two upright posts on the other side relative to the track, so that constructors can go up and down along the vertical ladder and can be protected by the protective cage, and the up-and-down safety is ensured. The operation platform is provided with the rail all around, can ensure the safety of operation construction. The four corners of the chassis frame are respectively externally connected with outwardly extending supporting leg cross beams 15, downward supporting legs 16 are arranged at the bottoms of the supporting leg cross beams, and the supporting legs 16 are supported on the ground after the operation trolley moves to a specified construction position, so that the stability of the operation trolley is ensured, and the operation trolley cannot move. The supporting surface of the chassis frame is lengthened by the extended supporting leg cross beams, so that the supporting is more stable, and the operation trolley is effectively prevented from inclining or toppling. The connecting structure of the supporting leg cross beam and the supporting leg can be made into a structure as shown in fig. 5, the outer end of the supporting leg cross beam 15 is connected with the top end of the supporting leg 16 through a first bolt 22, and when the operation trolley needs to be moved, the supporting leg is rotated and lifted to be away from the ground so as not to influence the movement of the operation trolley. In this case, the height of the legs should be greater than the diameter of the rollers. After the operation trolley moves to the right position, the supporting legs are rotated to be erected on the ground, and the first bolt is screwed. The connecting structure of the supporting leg cross beam and the supporting leg can be manufactured into a structure shown in fig. 6, the supporting leg cross beam 15 and the supporting leg 16 are fixedly welded, the ground feet 23 are embedded in the ground of a construction point, and the supporting leg and the ground feet are stably connected through second bolts 24. In this case, the height of the legs should be smaller than the diameter of the roller. A transverse supporting rod 17 and a cross supporting rod 18 are connected between two adjacent upright columns to enhance the connection strength and the structural stability between the upright columns. Bamboo plywood 19 is laid on the work platform to prevent slipping. A motor 20 for driving the rollers to move and a steering wheel 21 for controlling the rollers to rotate are arranged on the chassis frame, and the steering wheel controls the rollers to rotate through a steering system. The steering system adopts the vehicle steering system in the prior art, the connection control mode of the steering wheel and the steering system and the connection control mode of the steering system and the rollers are both in the prior art, and the vehicle steering system can be designed and manufactured by technicians in the field according to the prior art.
