Background technique

At present, the design of highway bridge crash barriers can be roughly divided into three types according to the combination with the beam, namely, ordinary sitting crash barriers, cast-in-place concrete crash barriers with hanging eaves, and prefabricated hanging plate crash barriers. With the improvement of people's aesthetic requirements, the ordinary seated anti-collision barriers can no longer meet the aesthetic needs. The current highway bridge anti-collision barriers mostly use cast-in-place concrete anti-collision barriers with hanging eaves and prefabricated hanging plate anti-collision barriers to show the bridge Design beauty.

The cast-in-place concrete anti-collision barriers with hanging eaves are frequently used, and the cast-in-place construction technology is generally used. When the formwork is installed and disassembled for construction, the construction personnel are working at a high place on the edge, and the construction risk is high, which can easily lead to production safety accidents and affect Construction quality of bridge crash barriers. At present, there is still a lack of a set of safe and mature construction supporting equipment in China. Most of the construction is organized by small cranes. There are many problems such as large investment in personnel, large investment in mechanical equipment, slow construction progress and no effective guarantee for production safety.

Utility model content

The purpose of the utility model is to provide a mobile trolley for the construction of the bridge anti-collision guardrail in view of the problems of inconvenient movement and inability to guarantee the safety of construction workers during the installation and removal of the formwork in the construction of the current bridge anti-collision guardrail.

In order to achieve the above object, the utility model adopts the following technical solutions.

A mobile bridge anti-collision guardrail construction operation trolley, including a truss, a base 4, a counterweight 7, and a crane 8; it is characterized in that:

The truss includes a column 1, a beam 2 and a brace 3, the lower end of the truss column 1 is fixedly connected to the base, the upper end of the truss is fixedly connected to the beam, and the beam 2 and the column 1 are respectively fixed by the braces 3 on both sides;

The beam 2 is divided into cantilevers on both sides with the column 1 as the boundary, an adjustable counterweight 7 is installed on one side, and a walkable crane 8 is installed on the other side.

The utility model further includes the following preferred solutions:

The truss column 1 is fully welded and consolidated with the chassis.

Universal pulley 5 with braking device 6 is installed at the four corners of the base.

The anti-collision limiting device 10 is installed on the upper side of the cantilever two ends of the crane 8.

The crane 8 lifts the guardrail steel formwork 11 through the hook 9, wherein the guardrail steel formwork 11 is formed by fixing the two steel formworks by pulling bolts 16 up and down.

The hanging basket that can be used for going up and down personnel is installed on the outer end of the cantilever of crane 8.

Suspender 12 and vertical pedestrian ladder 13 are installed at the outer end of the cantilever of crane 8, horizontal connecting rod 14 is set at the bottom of boom 12, dense mesh 15 is set up in the middle of connecting rod 14, and the bottom end is arranged full of scaffolding 17.

The utility model is simple in principle and easy to operate. The guardrail formwork can be mechanized, transported and installed through the horizontal movement of the crane, and the formwork can be moved longitudinally by the longitudinal movement of the trolley, so as to achieve the purpose of mechanical form removal and longitudinal translational transportation. At the same time, the hanging basket can be used as The working platform for the construction personnel on the outside ensures the safety of the construction personnel; the application of the anti-collision guardrail construction operation trolley ensures the construction safety, reduces the construction cost, improves the construction efficiency, and has remarkable social and economic benefits.
