Description
Technical field
The utility model is related to a kind of maintenance ladders, and in particular to a kind of bridge outside maintenance ladder.
Background technology
Being significantly increased for volume of transport is crossed recently as me, rate of traffic flow and vehicle capacity are increasing, this
Completely new challenge is formd for the safety of bridge, bridge management appropriate and maintenance can avoid because bridge collapse etc. is asked
Contingency caused by entitled.Therefore, reinforce the daily maintenance of bridge, the service life of bridge can be extended, to save
The expense of secondary construction is saved.Bridge side apparatus for examination and repair is a kind of operation horizontal of the maintenance bridge provided for bridge maintenance personnel
Platform can safely and fast allow service personnel to reach the job position of bridge maintenance in this way, and flow detection or dimension are carried out to bridge
Repair operation.The repair apparatus of current existing daily bridge side, using bearing frame, load-bearing are arranged on the inside of Bridge guardrail
The maintenance ladder stretched out in outside bridge side is installed on frame, in addition also to be placed on bearing frame clump weight to maintenance ladder into
Row support.It is required for loading the clump weight of corresponding weight on bearing frame when using every time, and the movement of bearing frame needs
Clump weight is unloaded, it is not only troublesome in poeration, increase the working strength of operating personnel.
In order to solve the above-mentioned technical problem, inventor devises a kind of bridge outside maintenance dress being supported using vehicle
It sets, including support plate, the top surface of support plate is fixedly connected with the maintenance ladder that can be reached on the outside of bridge railing, support plate
Bottom surface be respectively fixedly connected at least three it is vertically arranged and can be to the support leg that support plate is supported, the top surface of support plate
And it is also fixedly connected with lifting body positioned at the position at the rear of maintenance ladder, the upper horizontal of lifting body is provided with one piece of top
The top of plate, lifting body has a jacking axis that can vertically stretch and be fixedly connected with top plate, when jacking axis
When minimum value in its stroke, the distance between top plate top surface to ground be less than between vehicle chassis to be supported and ground away from
From when jacking axis stretching, top plate can be connected on vehicle chassis to be supported to compress on the ground support plate.Due to inspection
Repairing the part that ladder stretches out in outside bridge railing can not be supported, and operating personnel are susceptible to shaking when upper and lower, so not
There is only security risks, in addition also be easy to cause the fatigue of metal, reduce the service life of maintenance ladder.So maintenance ladder is answered
How to design, can have many advantages, such as that support is firm, usage safety performance is high, this is only further considerable ask
Topic.
Utility model content
In view of the above shortcomings of the prior art, technical problem to be solved in the utility model is：How a kind of is provided
Support is firm, maintenance ladder on the outside of the high bridge of usage safety performance.
In order to solve the above-mentioned technical problem, the utility model uses the following technical solution：
Maintenance ladder on the outside of a kind of bridge, including pedestal are fixedly connected with towards stretching in front of it at the top of pedestal
Bar shaped pedal, along the guardrail extended along its length is respectively fixedly connected with, bar shaped pedal is close for the two sides of bar shaped pedal
The position of its front end is fixedly connected with the cat ladder being arranged straight down, the bottom of cat ladder and is fixedly connected towards the side at its rear
There is a horizontally disposed operating platform, the bottom surface of bar shaped pedal and be fixedly connected with supporting mechanism positioned at the position at cat ladder rear, props up
The lower horizontal of support mechanism is provided with one piece of backing plate, the bottom of supporting mechanism have one can vertically stretch and with pad
The support shaft that plate is fixedly connected, when support shaft is stretched out, backing plate can be connected to the top of bridge railing with to bar shaped pedal into
Row support.
In the present invention, bar shaped pedal stretches out in outside bridge railing, keeps backing plate opposite with the bridge railing of lower section, so
Control supporting mechanism stretches out support shaft afterwards, so that backing plate is connected to the top of bridge railing, is propped up bar shaped pedal by railing
In addition support, has been further added by a supporting point to bar shaped pedal other than pedestal, and this supporting point is close to cat ladder
Position increases the intensity of bar shaped pedal and the stability of cat ladder, improves the service life of bar shaped pedal, avoids cat ladder and goes out
It now shakes, while also improving the safety used.
As an optimization, the cat ladder include two in left-right direction with respect to and vertically arranged side lever, between side lever and edge
Side lever length direction uniform intervals are provided with the cross bar of more left and right settings, and the both ends of cross bar are respectively fixedly connected with one where it
On on the inside of the side lever of side, the upper end of two side levers is respectively fixedly connected on the bottom surface of the bar shaped pedal, the bar shaped pedal
And being offered positioned at the position at the cat ladder rear can be such that operating personnel pass through with the opening I for the cat ladder that crawls toward, the cat ladder position
Side in front of it is horizontally disposed a tool platform, tool platform have the interconnecting piece that is slidably connected respectively with two side levers with
