Description

Technical Field

[0001] This invention belongs to the technical field of bridge construction equipment, specifically relating to a bridge outer construction platform for highway bridge construction and its working method. Background Technology

[0002] Highway bridge engineering refers to all work related to the planning, design, construction, maintenance, and repair of structures that cross waterways, valleys, and other transportation routes. Highways pass through rivers, harbors, lakes, reservoirs, irrigation canals, or other bodies of water, or cross deep valleys with significant elevation differences, or cross other transportation routes. Bridges are necessary to maintain smooth traffic flow. In bustling urban areas, elevated highways are sometimes required. For mountain roads, due to the extensive excavation of the roadbed, unstable geological structures, or the need to protect the landscape, elevated bridges are sometimes constructed instead of a roadbed.

[0003] A construction platform in the conventional sense is a steel frame structure system erected by scaffolding, used to assist in the construction of building projects. However, in the construction of bridges, in addition to the steel frame structure system, it is also necessary to install drainage pipes and other power lines on the outside of the viaduct. Therefore, a specially designed mobile construction platform is needed to assist in the construction and facilitate the erection work of the workers.

[0004] Existing bridge external construction platforms are limited by the inclination of the underside of the viaduct platform during use, making it difficult to carry out close-range construction of drainage pipes and other power lines, resulting in low construction efficiency. To address this, we propose a bridge external construction platform for highway bridge construction and its working method. Summary of the Invention

[0005] The purpose of this invention is to provide a bridge outer construction platform and its working method for highway bridge construction.

[0019] As a preferred embodiment of the present invention, a buffer plate is fixedly connected to the top of the mobile platform.

[0020] The working method based on the bridge external construction platform for highway bridge construction includes the following steps:

[0021] S1, Rotational Arrangement:

[0022] Start the rotating motor, and the output end of the rotating motor drives the worm to rotate. The worm meshes with the turbine to drive the turbine to rotate. The turbine drives the rotating arm to rotate, and the rotating arm drives the construction railing to rotate, thus realizing the rotating arrangement of the construction railing.

[0023] S2, Lifting / Moving:

[0024] Activate the pneumatic push rod, and the output end of the pneumatic push rod pushes the third telescopic rod to descend. Then, the second telescopic rod descends in the sliding cooperation of multiple first sliders and multiple first receiving slots, and the third telescopic rod descends in the sliding cooperation of multiple second receiving slots and multiple second sliders, thereby realizing the lifting and lowering movement of the construction railing.

[0025] S3, Deflection Movement:

[0026] Start the rotating gear, and the output end of the rotating gear drives the rotating motor to rotate. The rotating motor drives the driven gear to rotate through meshing with the driven gear. The driven gear drives the first telescopic rod to rotate, the first telescopic rod drives the second telescopic rod to rotate, the second telescopic rod drives the third telescopic rod to rotate, the third telescopic rod drives the mounting plate to rotate, and then drives the fixed block to rotate, so as to realize the offset rotation of the construction railing.

[0027] S4, Promoting Approach:

[0028] Start the drive motor, and the output end of the drive motor drives the lead screw to rotate. The lead screw pushes the support slider to move through the sliding engagement with the support slider. The support slider drives the construction railing to move. With the sliding engagement of the two limit grooves and the two limit blocks, the support slider is guided. At the same time, the two support grooves and the two support blocks slide to provide auxiliary support for the construction railing, so as to achieve the tilting and pushing of the construction railing and the elevated platform to approach each other.

[0029] S5, Auxiliary Support:

[0030] When the construction railing approaches the inclined side of the elevated platform, the rollers roll and fit against the inclined side. During the movement of the entire equipment, the rollers prevent the construction railing from shifting, thus providing auxiliary support for the construction railing.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. In this scheme, the drive motor is started, and the output end of the drive motor drives the lead screw to rotate. The lead screw pushes the support slider to move through the sliding engagement with the support slider. The support slider drives the construction railing to move. With the sliding engagement of two limit grooves and two limit blocks, the support slider is guided. At the same time, the two support grooves and two support blocks slide to provide auxiliary support for the construction railing, so that the construction railing is tilted and pushed close to the elevated platform, so that one end of the construction railing is close to the side end of the elevated platform. This eliminates the influence of the underside inclination of the elevated bridge platform, facilitates the installation of drainage pipes and other power lines, enables close-range construction, and improves construction efficiency.

[0033] 2. In this scheme, the pneumatic push rod is activated, and the output end of the pneumatic push rod pushes the third telescopic rod to descend. Subsequently, the second telescopic rod descends under the sliding cooperation of multiple first sliders and multiple first receiving slots. The third telescopic rod descends under the sliding cooperation of multiple second receiving slots and multiple second sliders, thereby realizing the lifting and lowering movement of the construction railing. By lifting and lowering the construction railing, it is convenient to move the construction personnel to the inclined side of the elevated platform, change the positional relationship between the construction personnel and the inclined side of the push motor, and adapt to different erection needs.

[0034] 3. In this scheme, the rotating gear is activated, and the output end of the rotating gear drives the rotating motor to rotate. The rotating motor, through meshing with the driven gear, drives the driven gear to rotate. The driven gear drives the first telescopic rod to rotate, the first telescopic rod drives the second telescopic rod to rotate, the second telescopic rod drives the third telescopic rod to rotate, and the third telescopic rod drives the mounting plate to rotate, which in turn drives the fixed block to rotate, thereby achieving the offset rotation of the construction railing. This allows the construction railing to be rotated, making it easier to adapt to the proximity of one end of the construction railing to the side of different elevated platforms, facilitating the installation of drainage pipes and other power lines on the side of the elevated platform by workers.

Then, the second telescopic rod 14 descends under the sliding cooperation of multiple first sliders 16 and multiple first receiving slots 13, and the third telescopic rod 17 descends under the sliding cooperation of multiple second receiving slots 15 and multiple second sliders 18, thereby realizing the raising and lowering movement of the construction railing 30. By raising and lowering the construction railing 30, it is convenient to move the construction personnel to the inclined side of the elevated platform 35, change the positional relationship between the construction personnel and the inclined side of the push motor 25, and adapt to different erection needs.

The roller 33 rolls against the inclined side of the elevated platform 35. When the construction railing 30 approaches the inclined side of the elevated platform 35 and comes into contact, the roller 33 rolls against the inclined end. During the movement of the entire equipment, the roller 33 prevents the construction railing 30 from shifting, thereby providing auxiliary support for the construction railing 30.

[0075] S2, Lifting / Moving:

[0076] Activate the pneumatic push rod 19.
