Description

Special equipment for construction and maintenance of mobile bridge guardrail

technical field

The invention relates to a new type of construction equipment, in particular to a small construction equipment that can simultaneously provide a mobile construction platform and lift heavy objects.

Background technique

During the construction of the bridge structure guardrail, the construction personnel must operate on the outside of the bridge. In order to complete the construction work, there are usually two solutions: one is to build a scaffold from under the bridge as an operating platform, and the crane on the bridge provides the formwork. The advantage of this scheme is high safety, but the disadvantage is that the guardrail is a linear structure, and the scaffolding that needs to be erected is relatively long, which wastes manpower and material resources when the bridge is high, and there is no support for erecting supports when there are ponds, river ditches, and passages under the bridge The second is to use a crane to hang the gondola from the bridge deck to provide an operating platform for the operator, and another crane to provide the formwork. This solution can solve the defects of the first solution; the disadvantage is that two cranes are required for the construction of the guardrail at the same time, and the cost is relatively high; in addition, the conventional mobile crane has a large volume and weight, and it needs to occupy a large construction space during construction. Unnecessary damage to bridge structures under construction.

The equipment can provide a mobile construction platform and lift heavy objects at the same time.

The technical solution of the present invention is: a mobile bridge guardrail construction and maintenance special equipment, including a frame body with casters, characterized in that: the frame body is provided with a lifting construction platform system for hoisting construction personnel, so The frame body is also provided with a hoisting system for hoisting heavy objects to the lifting construction platform system.

In a preferred embodiment, the upper side of the frame body is laterally provided with support beams and rails whose length is greater than the width of the frame body, and the elevating construction platform system includes The first electric trolley, a first electric hoist is arranged under the first electric trolley, and a hanging basket for construction is hoisted on the first electric hoist; The second electric trolley, a second electric hoist is arranged under the second electric trolley, and a hook for lifting heavy objects is arranged on the second electric hoist.

In a preferred embodiment, brake blocks for preventing the first electric trolley and the second electric trolley from slipping off the rail are provided at both ends of the steel rail.

In a preferred embodiment, the above-mentioned casters are universal wheels.

In a preferred embodiment, the above-mentioned rails are provided with counterweights.

In a preferred embodiment, the above-mentioned frame body is provided with counterweights.

In a preferred embodiment, the control end of the first electric hoist is placed in the hanging basket, and the control end of the second electric hoist is placed on the frame body.

In a preferred embodiment, the above-mentioned frame body includes a chassis, four universal wheels are installed on the lower part of the chassis, four support columns are welded on the upper part of the chassis, and two support beams with steel rails are welded on the support columns. on the upper end.

Compared with the prior art, the present invention has the following advantages: firstly, the structure is simple, easy to use, saves construction space, and is convenient for organizing construction; secondly, it is simple to manufacture and low in cost; thirdly, it is low in energy consumption and achieves the effect of energy saving and emission reduction ; Fourth, it is light in weight, which reduces the possibility of damaging the bridge under construction.
