As shown in figures 1-5, the bridge construction operation platform convenient to install comprises a J-shaped descending ladder cage 1, wherein the J-shaped descending ladder cage is opposite to the position and shape of a bridge guardrail, so that the descending ladder cage is hooked on the bridge guardrail. Descending ladder cage 1 is formed by the steel pipe connection for the installation slides the subassembly to support and connect construction platform 5, form the ladder that the workman climbed from top to bottom on the descending ladder cage.

The inner of descending ladder cage 1 is equipped with and slides subassembly 2, slides subassembly 2 and 6 sliding fit of bridge railing, realizes the free slip of descending ladder cage on bridge railing. The construction position can be adjusted at will, and the hanging basket is dismantled and fixed without repeated up and down operation of workers so as to adjust the construction position.

The sliding assembly 2 comprises an outer pulley, an upper pulley and an inner pulley, wherein the outer pulley, the upper pulley and the inner pulley are arranged in a front-back mode, and sliding stability is guaranteed. The cooperation of the outside of outer pulley and bridge railing 6, the cooperation of the upside of upper pulley and bridge railing 6, the cooperation of interior pulley and bridge railing 6's inboard realizes down trilateral sliding fit of ladder cage and bridge railing, guarantees gliding reliable and stable.

The outer pulley and the inner pulley are all obliquely arranged and are low-end in contact with the bridge guardrail 6, so that the inner and outer pulleys are matched with the inclined plane of the inner end and the outer end of the bridge guardrail, and the pulleys are prevented from generating large bending moment. The outer pulley is located the downside of electronic box, takes place to interfere with the electronic box when avoiding outer pulley walking, and the electronic box is the block terminal of electric appliances such as street lamp on the bridge railing.

The lower extreme welding of down ladder cage 1 has fixed plate 3, and fixed plate 3 is used for personnel's the construction of standing, makes things convenient for the workman to repair the outside of guardrail, guarantees that the outward appearance of guardrail is neat, image good.

Articulated through the hinge on the fixed plate 3 have returning face plate 4 to returning face plate 4 is relative with the ladder of descending ladder cage 1, when the workman need be down on the construction platform, opens the returning face plate, opens a passageway that can pass through, makes personnel can be smoothly down to the construction platform.

Wear to be equipped with the bayonet lock on the down ladder cage 1, bayonet lock and 4 card settings of returning face plate cooperate, when the workman carries out the guardrail repaiies, block the returning face plate with the bayonet lock, avoid its activity, guarantee the fixed of returning face plate, when the workman need pass through the fixed plate, take the bayonet lock out, make the returning face plate freely overturn.

The construction platform 5 comprises a rear frame 51, a front frame 52, an end frame 53 and a base frame 54. The rear frame 51, the front frame 52 and the end frame 53 are side rectangular frames formed by connecting steel pipes, and the steel pipes arranged diagonally are arranged inside the side rectangular frames to enclose and shield workers. The bottom frame 54 is a bottom rectangular frame formed by connecting steel pipes, and a walking plate 55 is arranged on the bottom rectangular frame and used for standing construction of personnel.

The left end and the right end of the rear frame 51 are hinged with the end frame 53 through pipe hinges, the lower end of the rear frame 51 is hinged with the rear end of the bottom frame 54 through pipe hinges, the front end of the bottom frame 54 is hinged with the front frame 52 through pipe hinges, and the end frame 53 is detachably connected with the bottom frame 54 and the front frame 52 respectively.

Because the construction platform is arranged below the bridge, the construction platform with the fixed structure cannot be installed on the bridge guardrail, the foldable structure is adopted, the construction platform is unfolded when the descending ladder cage is hoisted, and the descending ladder cage can be simply and quickly placed on the bridge guardrail. And then the construction platforms are combined and connected to form a stable construction platform.

The pipe hinge part comprises two pipe clamps, the pipe clamps are used for clamping and fixing steel pipes on two hinged frames, and the two pipe clamps are hinged through a rotating shaft to realize hinged connection of the two frames. The clamping sleeve 56 is welded on the end frame 53, the clamping end 57 is welded on the descending ladder cage 1, the front frame 52 and the bottom frame 54, and the clamping end 57 extends into the clamping sleeve 56 and is connected with the clamping sleeve 56 through the fixing bolt 58, so that the detachable connection of the construction platform is realized.

Because construction platform extends to the below of bridge, can be under construction the drain pipe, improve operation platform's functionality and utilization ratio.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
