Abstract
The invention discloses a modular bridge erecting mechanism, and belongs to the technical field of bridge erecting equipment. The erecting mechanism comprises a push rod, a support rod, a modular bridge section and a propulsion power unit; one end of the modularized bridge section is horizontally and fixedly connected with the push rod, the other end of the modularized bridge section is movably connected with the end part of the support rod, the propulsion power unit pushes the modularized bridge section to cross obstacles through the push rod along the horizontal direction, the support rod plays a role in rotating a fulcrum and assisting in supporting in the crossing process, and the modularized bridge section is erected after arriving at an opposite bank and being horizontally arranged. The invention can eliminate the bad geological conditions to quickly reach the bridge erection site, and meets the requirement of diversification of bridge erection modes.
Description
Technical Field
The invention relates to the technical field of bridge erection equipment, in particular to a method and a mechanism for erecting modular bridge field emergency rescue.
Background
When a road is interrupted due to a hostile geological disaster accident, a material transportation road is firstly communicated, and the method is mainly realized by a mechanical bridge which is quickly erected and a manually assembled Bailey bridge at present. The mechanical bridge erection has high efficiency, high speed and good maneuvering performance, but when severe disasters occur, the damage to the site road condition and environment is serious, the erection requirement can be met only by preprocessing the site for the mechanical bridge erection, and the actual erection time of the mechanical bridge is influenced to a certain extent; meanwhile, the bearing capacity of the road conditions on the spot in a disaster area is poor, so that the heavy mechanized bridge cannot reach the rescue spot at the first time.
Disclosure of Invention
In view of this, the invention provides a modular bridge erecting mechanism, which can eliminate severe geological conditions and quickly reach a bridge erecting site, and meet the requirement of diversification of bridge erecting modes.
A modularized bridge erecting mechanism comprises a push rod, a support rod, a modularized bridge section and a propulsion power unit;
one end and the push rod level fixed connection of modularization bridge section, the other end of modularization bridge section and the tip swing joint of bracing piece, impel power unit and pass through the push rod along the level and promote modularization bridge section and stride across the obstacle, the bracing piece plays rotation fulcrum and auxiliary stay effect at strideing across the in-process, and arrival of crossing the bank and put the after-erection completion horizontally when modularization bridge section.
Further, in order to reduce the motion friction force between the modular bridge sections and the ground, rollers are installed at the bottoms of the modular bridge sections, and form rolling pairs with the ground.
Further, the propulsion power unit adopts a bulldozer or an excavator.
Has the advantages that:
1. the invention can complete the erection work by horizontally pushing the modular bridge section by the propulsion power unit, the supporting rod plays a role of a lever fulcrum in the erection process, the horizontal thrust is ingeniously converted into the supporting force for the modular bridge section, and the unidirectional erection work can be completed without auxiliary equipment.
2. The mechanism propulsion power unit can be diversified, engineering machinery such as a bulldozer, an excavator and the like on a rescue site can be used as the propulsion power unit to finish modular bridge erection horizontal power sources, and the situation that similar heavy mechanized bridge erection can be finished only by a bridge erection vehicle per se is avoided; the modular bridge erecting mechanism provided by the invention is simple and easy to realize and operate, and has stronger site adaptability.

Detailed Description
The invention is described in detail below by way of example with reference to the accompanying drawings.
As shown in fig. 1 and 2, the invention provides a modular bridge erecting mechanism, which comprises a support rod 1, a push rod 7, a modular bridge section 2, a rotating shaft 3, a roller 4, a roller shaft 5 and a propulsion power unit 6, wherein the modular bridge section 2 is an integrated integral structure, and the length of the modular bridge section is greater than the width of a barrier to be spanned;
one end of the modularized bridge section 2 is fixedly connected with the push rod 7, the other end of the modularized bridge section 2 is hinged with the support rod 1 through the rotating shaft 3, and the bottom surface of the modularized bridge section 2 is provided with the roller 4 through the roller shaft 3, so that the modularized bridge section 2 can move more conveniently under the pushing of the propelling power unit 6.
The erection process is as follows: as shown in fig. 3, when a modular bridge needs to be erected, the propulsion power unit 6 pushes the push rod 7 connected with the propulsion power unit, and a rolling pair is formed between the rolling wheel 4 arranged at the bottom of each of the two ends of the modular bridge section 2 and the ground and advances forwards, as shown in fig. 4 and 5, when the modular bridge section 2 reaches an excavation or damages a bridge, the front end support rod 1 descends and supports the bottom surface of the excavation due to gravity, as shown in fig. 6, the modular bridge section 2 rotates around the rotating shaft 3 of the front end support rod 1 and advances forwards to an opposite bank to complete the erection operation along with the continuous forward propulsion of the propulsion power unit 6.
In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
