In the application process of the novel waterproof cloth laying trolley provided by the embodiment, the hoisting mechanism 1 drives the steel bar mounting frame 3, the turnover mechanism is full of materials and overturns in place, namely, the pressing block touches the turnover in-place travel switch 16, the hoisting mechanism 1 stops working automatically, the positioning oil cylinder 15 pushes the oil cylinder positioning shaft 10 to position the turnover hinging seat 9, meanwhile, the pulley positioning mechanism 11 tightly supports the turnover hinging seat 9, the positioning oil cylinder in-place travel switch 18 can sense that the oil cylinder positioning shaft 10 is in place, specifically, a small-sized control box can be manufactured, wherein a red light indicates that the oil cylinder positioning shaft 10 is not sensed and gives an alarm, a green light indicates that the oil cylinder positioning shaft is normally displayed, the hoisting mechanism 1 releases the pressure, a steel wire rope is manually removed, the two motor driving devices 5 synchronously drive to walk to corresponding positions under manual inching control, the mounting frame steel bar 3 walks simultaneously and gives an alarm sound to walk, the reinforcing steel bar is taken out from the reinforcing steel bar mounting frame 3 manually, the reinforcing steel bar is tied up in the waterproof layer until the reinforcing steel bar is taken out completely and tied up, two motor drive devices 5 drive the reinforcing steel bar mounting frame 3 to walk to the tail end of the cloth-proof trolley, the walking is simultaneously and the alarm sounds, the steel wire rope is installed to the hook pulley manually, the hoisting mechanism 1 moves forwards, the positioning oil cylinder 15 drive oil cylinder positioning shaft 10 return stops, the positioning oil cylinder return stroke switch 17 can be touched when the oil cylinder positioning shaft 10 return, the positioning oil cylinder 15 return detection can be carried out, the hoisting mechanism 1 drives the reinforcing steel bar mounting frame 3 to overturn to the ground, the reinforcing steel bar is installed to the overturning frame manually until the reinforcing steel bar.
In the novel waterproof cloth laying trolley provided by the embodiment, the reinforcing steel bar mounting frame 1 is designed into a mechanism capable of walking in a reciprocating manner, and reinforcing steel bars can be conveyed to corresponding positions through the mounting frame walking mechanism, so that the reinforcing steel bars are prevented from being mounted to the corresponding positions through manual cooperative operation, and the labor intensity of workers is greatly reduced; the time of manual reciprocating walking operation is saved, and the labor production efficiency is greatly improved.
In addition, the novel tarpaulin laying trolley that this embodiment provided can realize the automatic upset of mounting bracket, designs into initial upset mounting bracket and horizontal position and becomes 90, and the pin joint of the articulated seat of upset 9 sets up in one side of the barycenter position partial to walking track assembly of steel bar mounting bracket, and the steel bar mounting bracket is received the automatic upset of action of gravity when initial position, has avoided the manual work to intervene the upset that carries out initial position by force, reduces artifical intensity of labour.
So, the tarpaulin laying trolley that this embodiment provided is in the use, need not to consume huge manpower and carry out the installation of reinforcing bar with the reinforcing bar mounting bracket upset to with the horizontal plane parallel, after the steel bar installation, also need not to consume a large amount of manpowers and promote the reinforcing bar mounting bracket upset to packing up the state, the reinforcing bar mounting bracket can be moved along walking track assembly on the installation bed frame, need not to consume a large amount of manpowers and promote the reinforcing bar mounting bracket, compared with the prior art, it is convenient to use, the flexibility ratio obtains the improvement that is showing, can alleviate required artificial strength in the use, and operating efficiency obtains obviously high, the time cost has been practiced thrift to a great extent.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
