A kind of bridge pier maintenance mast-up
Technical field
The present invention relates to bridge pier maintenance field, particularly a kind of bridge pier maintenance mast-up.
Background technology
Record according to interrelated data, the current bridge quantity of China has reached more than 50 ten thousand, builds respectively in different times, in recent years bridge to build development especially flourishing.Due to the important component part that bridge is road and rail traffic, its maintenance situation directly determines and affects the unimpeded of road and traffic safety, also namely directly affect economic benefit and the social benefit of road and rail traffic, in national economy, account for very important effect.
In recent years, the bridge of China is faced with the problem same with the bridge of numerous country in the world, that is exactly the growth of large quantities of bridge along with service life, enter " aging " stage fast, it in use, along with the interaction of environmental factor and traffic load, its technology status constantly worsens, and has been difficult to the traffic needs adapting to increasingly be good at.When reaching far away design service life, just there is the phenomenon of endurance quality serious degradation, therefore, being extremely necessary to carry out comprehensive service work to bridge in Partial Bridges.
Now, when overhauling bridge pier, conventional mast-up is manned comprehensively overhauls around bridge pier; But, existing bridge pier maintenance mast-up is generally rectangular structure, collide with when carrying out bridge pier maintenance and particularly overhauling Cylindrical Pier the frame of mast-up or guardrail unavoidably, and the easy like this deformed damaged causing mast-up, has had a strong impact on the application life of mast-up.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of bridge pier maintenance mast-up, and this mast-up is provided with maintenance frame and the universal wheel of arc, not only avoid the colliding with to mast-up when bridge pier overhauls, and increases maintenance area.
In order to realize the object solved the problems of the technologies described above, present invention employs following technical scheme:
A kind of bridge pier maintenance mast-up, particularly overhauls Cylindrical Pier for bridge pier maintenance, it is characterized in that: comprise hoisting ring, base plate, arc guardrail, two nonfloating rails, a movable rail and four universal wheels;
Described base plate is the flat board being provided with an arc side, and the radian of arc guardrail matches with the radian of dull and stereotyped arc side, and arc guardrail is vertically fixed on the arc side of base plate; Two nonfloating rails are vertically fixed on the both sides of base plate respectively and are connected with arc guardrail; The position of movable rail is corresponding with arc guardrail and movable rail both sides connect two nonfloating rails respectively; Movable rail while with a nonfloating rail by gemel connection, another side is connected by door bolt with another nonfloating rail; Four universal wheels are symmetricly set on arc protective marge side;
Described hoisting ring is arranged on the top of two nonfloating rails.
Concrete: described plate upper surface is provided with anti-skidding projection.Anti-skidding projection can be the lines of salient point or projection.
Preferred further, be provided with four road wheels below base plate.This set, facilitates the movement of bridge pier maintenance mast-up.
Using method: during use, after workman enters mast-up by movable rail, utilizing the hoisting ring on nonfloating rail to coordinate rope steadily to be sling by this mast-up, when overhauling bridge pier, making the arc guardrail of this mast-up just to bridge pier; When detecting Cylindrical Pier, because the intrados of arc guardrail and the side of bridge pier match, mast-up can be made more to press close to bridge pier, be not only convenient to the maintenance of workman, and facilitate workman and to place under repair operation; In addition, the corner of arc protective marge side is equipped with universal wheel, no matter be maintenance Cylindrical Pier or rectangular pier, can both be convenient to mast-up and press close to bridge pier motion and prevent colliding with between mast-up and bridge pier, when avoiding lifting, owing to colliding with to the infringement of bridge pier.
These technical schemes also can combine mutually or combine, thus reach better technique effect.
By adopting technique scheme, the present invention has following beneficial effect:
A kind of bridge pier maintenance mast-up of this patent, compared with traditional mast-up, can not only avoid the colliding with to mast-up when bridge pier overhaul, and increases maintenance area and be convenient to mast-up to press close to bridge pier and move; Make mast-up more press close to bridge pier, be not only convenient to the maintenance of workman, and facilitate workman and to place under repair operation; When it also avoid lifting, owing to colliding with to the infringement of bridge pier.

Detailed description of the invention
Below in conjunction with accompanying drawing, further explanation is explained to this patent.But the protection domain of this patent is not limited to concrete embodiment.
Embodiment 1
As shown in the figure, a kind of bridge pier maintenance mast-up of this patent, particularly overhauls Cylindrical Pier for bridge pier maintenance, it is characterized in that: comprise hoisting ring 3, base plate 6, arc guardrail 2, two nonfloating rails 4, movable rail 5 and four universal wheels 1.
Base plate 6 is for being provided with the flat board of an arc side, and the radian of arc guardrail 2 matches with the radian of dull and stereotyped arc side, and arc guardrail 2 is vertically fixed on the arc side of base plate 6; Two nonfloating rails 4 are vertically fixed on the both sides of base plate 6 respectively and are connected with arc guardrail 2; The position of movable rail 5 is corresponding with arc guardrail 2 and movable rail 5 both sides connect two nonfloating rails 4 respectively; Movable rail 5 while with a nonfloating rail 4 by gemel connection, another side is connected by door bolt with another nonfloating rail 4; Four universal wheels 1 are symmetricly set on arc guardrail 2 lateral surface; Hoisting ring 3 is arranged on the top of two nonfloating rails 4.
Wherein, base plate 6 upper surface is provided with anti-skidding projection, and anti-skidding projection can be the lines of salient point or projection; Base plate 6 is provided with four road wheels, this set below, facilitates the movement of bridge pier maintenance mast-up.
During use, after workman enters mast-up by movable rail 5, utilizing the hoisting ring 3 on nonfloating rail 4 to coordinate rope steadily to be sling by this mast-up, when overhauling bridge pier, making the arc guardrail 2 of this mast-up just to bridge pier; When detecting Cylindrical Pier, because the intrados of arc guardrail 2 and the side of bridge pier match, mast-up can be made more to press close to bridge pier, be not only convenient to the maintenance of workman, and facilitate workman and to place under repair operation; In addition, the corner of arc guardrail 2 lateral surface is equipped with universal wheel 1, no matter be maintenance Cylindrical Pier or rectangular pier, can both be convenient to mast-up and press close to bridge pier motion and prevent colliding with between mast-up and bridge pier, when avoiding lifting, owing to colliding with to the infringement of bridge pier.
