Personnel provide operating platform, so that welding, spray painting etc. be facilitated to operate.
In an embodiment of the invention, the construction of bridge high-altitude is specifically included with mobile climbing frame and forms portion by following
Point：
1, lower part climbing frame
The present invention is whole to be sleeved on bridge cabinet using slidably mode under real use state, bridge cabinet
Aerial setting, lower part climbing frame 1 install (being installed by top climbing frame 2) in the bottom of bridge cabinet.
Lower part climbing frame 1 use truss structural design, one cuboid framework structure of global approximation, lower part climbing frame 1 it is upper
Side is operating platform, the operation such as can weld, paint with auxiliary construction personnel.
Construction personnel needs using welding and spray painting operation by the way of lifting compared with the prior art, energy of the present invention
Safe and reliable, stable standing basis enough is provided for construction personnel, to ensure that construction personnel can be safer, more effectively
It is operated.
2, top climbing frame
The both ends of lower part climbing frame 1 are arranged in top climbing frame 2 and its setting height is higher than lower part climbing frame 1.It is actually using
Under state, the two sides of bridge cabinet are arranged in top climbing frame 2.
To those skilled in the art, the top surface of bridge cabinet is planar structure, still, the two sides of bridge cabinet with
And bottom is special-shaped shape.Since the two sides of bridge cabinet are arranged in top climbing frame 2, top climbing frame 2 uses abnormity
Body framework design.
Specifically, top climbing frame 2 is divided into lower part climbing frame 1 with two for two top climbing frames 2 in one group, same group
Both ends are simultaneously detachably connected with lower part climbing frame 1.
The end of lower part climbing frame 1 is arranged in top climbing frame 2, on the same end of lower part climbing frame 1, top climbing frame 2 can be only
There are two setting one or top climbing frame 2 can be set.When 2 quantity of top climbing frame being arranged on the same end of lower part climbing frame 1
When being one, top climbing frame 2 and the wide setting of lower part climbing frame 1；When the number of top climbing frame 2 being arranged on the same end of lower part climbing frame 1
When amount is two, the setting width of top climbing frame 2 is not more than the half of 1 width of lower part climbing frame.
Top climbing frame 2 is set to the upside of lower part climbing frame 1, uses and is detachably connected between top climbing frame 2 and lower part climbing frame 1
Structure achieves a fixed connection, and top climbing frame 2 is arranged the both ends to lower part climbing frame 1 and is formed with and bridge cabinet with lower part climbing frame 1
The identical avoiding space of substructure shape, such bridge cabinet can be encased in the avoiding space, that is, this hair
Bright set is attached to bridge cabinet.
3, rod assembly
The effect of rod assembly is that the top climbing frame 2 that will set up separately at 1 both ends of lower part climbing frame is attached, so that pull rod
Component, top climbing frame 2 and lower part climbing frame 1 form an entirety, improve overall structural strength of the invention.
Specifically, rod assembly includes drawbar unit, and drawbar unit includes pull rod 4, and the both ends of pull rod 4 are provided with company
The both ends of pull rod 4 are arrived in fishplate bar 5, the fixed setting of connecting plate 5, and pull rod 4 is fixedly connected by connecting plate 5 with top climbing frame 2, and top is climbed
Frame 2, lower part climbing frame 1 and rod assembly are formed with annular enclosed type frame structure, in this manner it is possible to which the present invention is sleeved on bridge
On spar-box body.Suspension arm 3 is provided on top climbing frame 2, the present invention is by installing pulley assembly on suspension arm 3, just
It can be slided on bridge cabinet.
Generally, construction equipment can be placed in the upper side of bridge cabinet, in order to these construction equipments (especially
Higher, the lesser equipment of width of height, such as crane machine) it is avoided, present invention particularly provides following optimization designs：Pull rod
Unit is provided with no less than two and is divided at least two groups, between the projection of two groups of adjacent drawbar units on the operational platform has
Every.In this way, will push the present invention in bridge box body-sliding, if encounter it is above-mentioned to sliding generate obstacle construction equipment (under
Face is referred to as barrier), it is possible to which the one group of drawbar unit that first will be close to barrier is dismantled, main body of the present invention is at it
It still is able to keep higher structural strength under the action of remaining drawbar unit to guarantee that it is smoothly mobile, then in first group of pull rod list
After first across obstacle, first group of drawbar unit is assembled, then successively remove other drawbar units, until whole pull rod lists
Member is across barrier.
For the ease of movement of the present invention on bridge cabinet, the invention proposes the designs of such as flowering structure：In top climbing frame 2
On be provided with suspension arm 3, in being provided with the pulley assembly that can be in rolling contact with the top surface of bridge cabinet on suspension arm 3.
The problem of suspension arm 3 is the maximum component of load-bearing in the present invention, is damaged in order to avoid its stress is excessive,
The present invention, which is defined on the same top climbing frame 2, is provided at least two suspension arms 3, is arranged on the same top climbing frame 2
Whole suspension arms 3 be located in the same plane parallel with operating platform；The suspension being arranged on whole top climbing frames 2
Support arm 3 is respectively positioned in approximately the same plane；Two suspensions branch in the suspension arm 3 being arranged on the same top climbing frame 2, adjacent
Reinforcing rod 6 is provided between arm 3.
Suspension arm 3 is fixedly installed by welding onto top climbing frame 2, or the mode being connected by screw bolts
It is fixedly installed onto top climbing frame 2.As soon as at least two suspension arms 3 are provided on top climbing frame 2, in this way, the present invention
It can be suspended on bridge cabinet by least four suspension arms 3, structure design can not only reduce single suspension arm 3
Stress degree, while can also improve what the present invention was hung on bridge cabinet by way of increasing with bridge cabinet contact point
Stability.
Also, the multiple suspension arms 3 being arranged on the same top climbing frame 2 in the width direction of top climbing frame 2 with
Largest interval mode is arranged at equal intervals, can increase the layout width of suspension arm 3 in this way, further increases the present invention and exists
The stability hung on bridge cabinet.
In order to improve the structural strength of suspension arm 3, the present invention preferentially selects I-steel, on the bottom surface of suspension arm 3
And the two sides for being located at its vertical bar symmetrically offer mounting hole a and are formed with mounting hole group, a mounting hole group is for installing one group
Pulley assembly.The reliability that pulley assembly is arranged on suspension arm 3 is improved in such manner, it is possible to improve.
In the present invention, pulley assembly includes pulley substrate 7, pulley support arm 8, pulley 9, screw rod 10 is turned up and is turned up
Nut 11, there are two pulley support arm 8 includes, two pulley support arms 8 are set to the bottom surface of pulley substrate 7 by welding
On, two pulley support arms 8 are arranged according to the width of pulley 9 using interval mode, and pulley 9 is set between two pulley support arms 8
And it is rotatably installed on pulley support arm 8 by pulley spindle.
Specifically, the axis of pulley spindle is parallel with the length direction of suspension arm 3.
By above structure it is found that being equipped with one group of pulley assembly in a mounting hole group, a mounting hole group is by two
Mounting hole composition, a height-regulating screw rod 10 are assembled with a mounting hole a, therefore, are turned up there are two the settings of screw rod 10, two
