Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, and in particular to a movable viaduct anti-collision wall construction platform and a construction method thereof. Background Art

[0002] As a protective structure on the outside of the bridge, the crash wall plays an important role in safety. The construction process includes steel bar binding, formwork installation, concrete pouring, concrete curing and other processes. When installing the formwork, the inner and outer formworks need to be hoisted and moved to both sides of the steel cage. The construction workers adjust the positions of the inner and outer formworks until they are aligned and then fixed with connectors, which makes the workflow too complicated, the formwork holes difficult to align, and manual operations prone to errors.

[0003] Patent application No. 202410859519.9 discloses an integrated crash barrier construction trolley, which adjusts the trolley posture through an automatic leveling system; realizes the installation and removal of the template through the template mechanism; pours concrete through the electronically controlled material distribution mechanism; demolds after the strength meets the requirements, lifts the template mechanism through the lifting mechanism, performs template grinding and other processes, and lowers the template mechanism after completion; and drives the above-mentioned mechanism as a whole to move along the length direction of the crash barrier through the walking mechanism to reach the next construction position. However, the above-mentioned patent mentions a solution in which the template is integrally connected to the hydraulic cylinder, which can improve the installation accuracy, but it also makes it impossible to separate the template from the construction trolley. It is necessary to wait for the previous crash barrier to be poured and dried before the template can be removed for the construction of the next crash barrier, which takes up the operation time of the construction trolley, is not conducive to continuous operation, and affects construction efficiency.

[0076] Specifically, the clamp arm assembly moves inward, the caliper 14 is clamped with the fixed plate 3, the clamping cylinder 15 pushes the caliper 14 out, and the caliper 14 pushes the fixed plate 3, so that the template is close to the steel cage 26 and the template is kept under pressure. At the same time, the top of the outer plate 8 is clamped with the top of the inner plate 9, and the rotary cylinder drives the rotary joint 12 to extend until the rotary joint 12 is plugged and fixed with the screw column 11, and the rotary motor drives the rotary joint 12 to rotate, so that the screw column 11 is screwed into the screw hole 10.

[0077] S7: The clamping arm assembly moves outward to release the clamping connection with the fixing plate 3, and the locking assembly moves upward to release the locking of the fixing hole 4. The lifting mechanism 1 controls the frame to rise, driving the clamping arm assembly to move upward and separate from the template, thereby completing the installation of the template and the steel cage 26.
