The overall structure principle of the present invention:

Now a hydraulic self-propelled anti-collision wall formwork trolley is provided, which adopts symmetrical arrangement on both sides, integral pouring construction and integral forward-moving construction. It is mainly composed of anti-collision wall formwork, including outer and inner formwork, hanging basket 11, gantry 3, walking wheel 8, telescopic beam, lifting oil cylinder, and demoulding positioning support.

1. The outer formwork and the inner formwork form the forming body required for the concrete of the crash wall. The outer formwork and the inner formwork are integral steel formwork, and a movable tie rod is set between the outer and inner formwork to fix the positions of the two. There is a positioning and demoulding oil cylinder between the outer formwork and the hanging basket. There is a positioning and demoulding cylinder between the inner formwork and the gantry. The outer formwork and the inner formwork are connected with the lifting cylinder through the ear seat.

2. The hanging basket is used for the construction platform of the outer formwork of the anti-collision wall and the positioning and reinforcement of the formwork. The gondola is located below one end of the traverse assembly.

3. The gantry is an overall skeleton, and the left and right sides are connected with telescopic beams, and the walking wheels that move forward and backward are located under the gantry. An oil cylinder for adjusting the position up and down is arranged between the traveling wheel and the gantry. The walking wheel can be located under the gantry, and can carry the whole trolley to move.

4. Under the telescopic beam, there is a hanging basket and the outer formwork carried by the lifting cylinder. The telescopic beam can carry the hanging basket and the horizontal adjustment position of the formwork.

5. The lifting cylinder is a telescopic beam as the movable connecting part between the formwork, which is convenient for the overall positioning adjustment and the demoulding of the formwork.

6. When demoulding, the formwork comes out to the outside, and then lifts upward as a whole through the lifting cylinder, so that the formwork is separated from the concrete.

Operation of the present invention:

The traveling wheel 8 drives the gantry 3 to move on the bridge. After moving to a predetermined position, the first positioning and demolding cylinder 15 and the second positioning and demolding cylinder 17 respectively control the outer formwork 131 and the inner formwork 132 to fold together to form the concrete for the crash wall. The required molded body, and the staff can adjust the second demolding positioning support 16 and the first demolding positioning support 14 between the inner template and the gantry to improve the positioning firmness of the template, and at the same time, the outer template can also be adjusted. The movable tie rod 19 is installed between the inner formwork and the inner formwork to further improve the forming effect. The staff drives the equipment to pour concrete into the formwork bodies on both sides of the gantry 3, and the concrete solidifies and forms into the anti-collision wall in the forming body; when the anti-collision wall is formed stably, The movable tie rod 19 and the demoulding positioning support are disassembled, the equipment drives the positioning demoulding cylinder to retract, and the formwork is protruded to the outside, and then the lifting cylinder is lifted upward as a whole, so that the formwork is separated from the concrete. The walking wheel 8 drives the equipment to move to the next construction point for construction.

When it is necessary to install the railing 24 on the anti-collision wall at one time, the staff puts the railing 24 into the U-shaped inner cavity of the ear seat 18 in advance, drives the synchronous cylinder 20 to retract, and can clamp the railing 24 on the ear seat. within 18. The construction is carried out according to the above-mentioned construction steps of the anti-collision wall. After the anti-collision wall is poured, the synchronous oil cylinder 20 is extended, the toothed plate 23 of the clamp block 21 is slowly moved to the outside, the railing 24 is slowly falling, and finally the railing 24 The support seat at the lower end is immersed in the concrete, and the demoulding operation can be started after the concrete is solidified. In order to prevent the railing 24 from being immersed into the concrete due to its too small mass, the lowering cylinder 25 can be activated, and the lowering cylinder 25 can exert downward pressure on the railing 24, so as to ensure that the supporting seat of the railing 24 and the anti-collision wall are in contact with each other. Concrete completes the immersion installation.
