Description
Technical field
The present invention relates to a kind of device that is used for the arch bridge inspection.
Background technology
The inspection of bridge comprises current check, makes regular check on, checks period unusually, is the top priority of bridge operation maintenance management, and purpose is the health status of timely discovery, diagnosis bridge.In the actual engineering and since a lot of positions of bridge be not easy near, therefore need accomplish inspection work by the inspection platform that bridge inspection equipment provides.
At present arch bridge has a wide range of applications on the highway of China and railway; Owing to lack advanced maintenance and inspection equipment, a large amount of arch bridges are long neglected and in disrepair, disease in various degree occurred; Directly have influence on the application life and the traveling security of bridge, demand special-purpose maintenance and inspection equipment urgently.
The existing inspection running mechanism that is used for the arch form bridge mainly contains following several kinds of patterns on the engineering at present: the one, adopt stride axis tile formula running mechanism; With the walking of stride walking mechanism axis tile device grip track, the climbing load that this mode can provide is less, and complex structure; Operation easier is big; Need frequent operation when advancing, fault rate is high, and safety is low; The 2nd, adopt the drawing running mechanism of hydraulic jack; Stretching walking through clamp mechanism grip track and hydraulic jack be applicable to that the bigger mechanism of load creeps on arch bridge, but this mode needs also a cover hydraulic system that power is provided; Increased the weight of entire mechanism; And the single operation stroke is limited, and slow walking needs multi-pass operation just can cover whole process to long-span arch bridge.In the face of present arch form bridge is widely used in the Rail Highway traffic, and because the gradient of arch form bridge is big, also high more to the requirement of checkout facility, original inspection running mechanism has been difficult to satisfy the required requirement of walking fast on heavy grade of arch bridge inspection.Therefore the arch form bridge inspection car that needs the extensive use of exploitation ability.
Summary of the invention
The technical problem that the present invention will solve is; Provide a kind of load big, can walk fast, the safe and reliable device that is used for the arch bridge inspection; The walking problem of the arch form bridge inspection car that solution is ubiquitous on arch, make the bridge inspection car can be convenient, on arch bridge, walk quickly and safely.
In order to solve the problems of the technologies described above, the technical scheme that the present invention proposes is: the said device that is used for the arch bridge inspection comprises bridge inspection car, first hoist engine, second hoist engine, first cable wire, second cable wire, walking track and directive wheel; Said first hoist engine and second hoist engine are arranged in respectively along the two ends of bridge to bridge arch; The first cable wire two ends link to each other with the bridge inspection car with first hoist engine respectively; The second cable wire two ends link to each other with the bridge inspection car with second hoist engine respectively, and directive wheel is installed on the bridge arch, and cable wire is walked around from directive wheel; The walking track laying is on bridge arch, and the bridge inspection car follows away orbital motion; When said bridge inspection car moves, be positioned at from the bridge inspection car and receive cable wire pulling bridge inspection car along bridge to the farther end hoist engine startup of distance, other end hoist engine is put cable wire synchronously, realization bridge inspection car moving back and forth on arch.
Said cable wire drives the bridge inspection car and moves under hoist engine drives, only play draw.Said directive wheel is installed on the arch, arranges along bridge arch, and cable wire changes direction through directive wheel, to adapt to different arch forms.Said walking track laying is spliced by the multistage rail on bridge arch, and the bridge inspection car follows away orbital motion, is born the gravity of bridge inspection car by the walking track.
As further improvement of the present invention; Configuration potential energy attenuating device and normally closed type mechanical brake on hoist engine; The potential energy that produces by acceleration of gravity when the potential energy attenuating device is used to reduce bridge inspection vehicle commander distance and moves downward; Strengthen the safety of operation, increased the application life of normally closed type mechanical brake simultaneously; The normally closed type mechanical brake plays braking action, normal operation normally closed type mechanical brake locking hoist engine, and hoist engine can not rotate, and when the bridge inspection car need move, starts the normally closed type mechanical brake, decontrols hoist engine and makes it to rotate pull line.
As a further improvement on the present invention, on the bridge inspection car, load the armstrong's patent brake, guaranteed that the bridge inspection car can be locked the walking track when cutting off the power supply or other abnormal conditions occurring, guaranteed its security.
The device of the arch bridge inspection that the present invention proposes; Adopt hoist engine to reel the type of drive that cable wire drives the bridge inspection car, once-through operation just can realize the long distance running of bridge inspection car on arch, can satisfy the requirement of walking fast of present large-scale arch bridge inspection trolley; On arch bridge, lay the walking track; Bear bridge inspection car weight power by the walking track, cable wire only provides tractive force, and the operation of bridge inspection car is more steadily reliable.In the hoisting equipment set inside potential energy attenuating device, solved when the bridge inspection vehicle commander moves apart from descending and received the acceleration of gravity effect and the more and more faster problem of speed.On the bridge inspection car, disposed the armstrong's patent check mechanism, guaranteed that the bridge inspection car can be fixed on safely on the walking track when outage or other abnormal conditions occurring.Whole apparatus structure is simple, simple operation, safe and reliable, cost is low, is applicable to various arch form bridges.
