Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, and in particular to a universal operating platform for large-size columns. Background Art

[0002] During the construction of bridges, it is necessary to construct the auxiliary facilities on the top of the column or its surface, so a temporary operating platform needs to be set up around the pier. The size of the operating platform should be compatible with the size of the column, so that technicians can construct the column on the operating platform. However, at present, different sizes of columns often require different sizes of operating platforms to be used, and even new operating platforms need to be modified on site. On the one hand, this greatly reduces the efficiency of construction operations and has low economic benefits. On the other hand, it is easy to cause danger during construction and cause personal harm. Summary of the invention

[0017] The features of the present invention and other related features are further described in detail below through embodiments in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:

[0018] like Figure 1-6 As shown in the figure, marks 1-15 respectively represent: single-sided operating platform 1, operating area 2, platform panel 3, guardrail 4, retractable guardrail 5, bidirectional sliding mechanism 6, slide rail 7, slide rail 8, channel steel 9, pulley 10, pulley 11, guide wheel 12, grid fence body 13, guide rail 14, sliding part 15.

[0019] Example: Figure 1 and Figure 2 As shown, the main body of the universal operating platform for large-size columns in this embodiment includes four single-sided operating platforms 1. The four single-sided operating platforms 1 enclose an operating area for the column, and the space enclosed by the four single-sided operating platforms 1 is consistent with the outer contour shape and size of the column to meet the construction needs of columns of different sizes.

[0020] like Figure 1 As shown, each single-sided operating platform 1 is provided with a platform panel 3, which is the operating area for construction workers, and the construction workers can move freely on the platform panel 3. The single-sided operating platforms 1 in this embodiment are arranged symmetrically in pairs, that is, the structures of the two single-sided operating platforms 1 on opposite sides are the same. Guardrails 4 are provided on one group of two single-sided operating platforms 1 on opposite sides, and retractable guardrails 5 are provided on the other group of two single-sided operating platforms 1 on opposite sides, so as to ensure the safety of construction workers during construction.

[0021] like Figure 2 As shown, slide rails 7 are symmetrically arranged at the bottom of two operating platforms 1 on opposite sides of one group, and slide rails 8 are symmetrically arranged at the bottom of two operating platforms 1 on opposite sides of another group. Both slide rails 7 and slide rails 8 are arranged along the length direction of the single-sided operating platform 1; slide rails 7 and slide rails 8 are in two planes with different height directions. A two-way sliding mechanism 6 is also arranged at the bottom of the single-sided operating platform 1. The two-way sliding mechanism 6 is arranged between two adjacent single-sided operating platforms 1. The two-way sliding mechanism 6 serves as an adjustment mechanism for the single-sided operating platform 1 on the one hand, and can be used to connect each single-sided operating platform 1 on the other hand to ensure the integrity of the universal operating platform.

[0022] Combination Figure 2 and Figure 4 As shown, the two-way sliding mechanism 6 is provided with a pulley 10 and a pulley 11 which are adapted to the slide rail 7 and the slide rail 8 respectively, wherein the pulley 10 is clamped in the slide rail 7 and the two form a sliding fit, and the pulley 11 is clamped in the slide rail 8 and forms a sliding fit. At this time, the distance between a group of single-sided operating platforms 1 on two opposite sides can be adjusted by sliding the pulley 10 of the two-way sliding mechanism 6 in the slide rail 7, and the distance between another group of single-sided operating platforms 1 on two opposite sides can be adjusted by sliding the pulley 11 in the slide rail 8, thereby adjusting the size of the operating area 2 according to the size of the column. Figure 1 and Figure 3 As shown, Figure 1 The size of the middle operating area 2 can be adjusted to Figure 3 to adapt the universal operating platform to switch between larger columns and smaller columns.

[0023] In order to further improve the accuracy and convenience of adjustment, Figure 4 As shown, a guide wheel 12 may be provided in the bidirectional sliding mechanism 6, and the guide wheel 12 may cooperate with the side of the slide rail, so as to limit and guide the sliding of the pulley on the slide rail.

[0024] like Figure 5 As shown, the single-sided operating platform 1 with the guardrail 4 side includes two slide rails 7 spaced apart at the bottom and a channel steel 9 arranged between the two slide rails 7, wherein the slide rails 7 and the channel steel 9 jointly support the platform panel 3. A more important function of the channel steel 9 is to serve as a sliding locking mechanism of the bidirectional sliding mechanism 6, such as Figure 5 As shown, the channel steel 9 is arranged parallel to the slide rail 7 and has the same length, and a plurality of connection holes are arranged in an array on the surface of the channel steel 9; after the pulley 10 of the two-way sliding mechanism 6 slides in the slide rail 7, the pulley 10 can be connected and fixed to the connection hole on the channel steel 9 by screwing the fixing bolts into the locking piece on the body of the two-way sliding mechanism 6, so that the position of the two-way sliding mechanism 6 is fixed, ensuring that after the adjustment of the universal operating platform is completed, its structure is stable and does not shake, thereby ensuring the safety of construction workers during construction. In implementation, the single-sided operating platform 1 with the retractable guardrail 5 is also provided with a channel steel 9 and a corresponding slide rail 8, and the structure is similar to the single-sided operating platform structure on the above-mentioned side.

[0025] like Figure 6 As shown, the retractable guardrail 5 is arranged on the single-sided operating platform 1 on the other side. The retractable guardrail 5 includes three layers of stacked grid fence bodies 13, the top and bottom of the middle grid fence body 13 are respectively provided with guide rails 14, and the top and bottom of the corresponding grid fence bodies on the outside are respectively provided with sliding members 15 carried in the guide rails 14, and the sliding members 15 and the guide rails 14 form a sliding fit, so that the three-layer grid fence body 13 forms a retractable structure. Through the sliding of the sliding member 15 in the guide rail 14, the grid fence bodies 13 on both sides of the stacking can be expanded or retracted to the two sides of the single-sided operating platform 1 from the middle grid fence body 13, thereby meeting the needs of safety protection during the construction of columns of different sizes.

[0026] In the specific implementation of this embodiment: each slide rail and guide rail can be made of channel steel, and the pulley and sliding member can be designed accordingly according to the groove shape of the channel steel.

[0027] Although the above embodiments have described the concepts and embodiments of the present invention in detail with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and changes can still be made to the present invention without departing from the scope of the claims, so they are not described in detail here.
