Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of railing base pouring, and particularly relates to a railing base pouring manipulator. BACKGROUND

[0002] The stainless steel railing of a municipal bridge generally comprises a plurality of support legs arranged at a certain interval, and the upper cross bar and the lower cross bar are fixedly connected with the support legs, and a plurality of vertical support rods are arranged between the upper cross bar and the lower cross bar of adjacent support legs, as shown in Figure 1 .

[0003] For the installation and construction of the stainless steel railing of a municipal bridge, there are two common ways, one of which is to first pour a base and pre-bury a steel plate on the base, and then fix the support legs of the stainless steel railing on the pre-buried steel plate through expansion screws; the other way is to first lay a row of reinforced concrete precast ground wraps on the edge of the bridge pavement, as shown in Figure 1 and Figure 2 , the ground wrap is inverted h-shaped, the top is U-shaped groove, the ground wrap is connected with the bridge steel bars by binding, and then the pavement is paved, so that the row of ground wraps becomes the installation base of the stainless steel railing, and then the support legs of the stainless steel railing are fixed on the pre-buried steel plate at the bottom of the U-shaped groove through expansion screws, and finally the U-shaped groove is filled with concrete, so that the stainless steel railing and the ground wraps are well bonded, and the safety factor of the railing is improved.

[0004] Obviously, the railing installed by the above-mentioned second installation method is more reliable in use, but when pouring concrete into the U-shaped groove of the ground wrap, the following problems exist: after the support legs of the stainless steel railing are placed in the U-shaped groove of the ground wrap, a gap G is formed between the lower cross bar and the top surface of the ground wrap, and N support legs divide the installation base formed by a plurality of ground wraps into N-1 filling sections. Due to the above pouring construction space problem, large equipment cannot be used for continuous pouring, and currently manual workers hold flexible pouring pipes to pour each filling section in sequence, which is labor-intensive. In addition, the concrete delivery is not stopped during the transition process, which causes the concrete to fall on the ground during the transition operation process, and the subsequent not only needs manual cleaning, but also wastes concrete. SUMMARY
