Automatic panel trimming and plastering machine for full concrete faced rockfill dam concrete panel construction line

Abstract

The invention discloses an automatic panel trimming and plastering machine for a full concrete faced rockfill dam concrete panel construction line. The automatic panel trimming and plastering machine comprises a main frame, main frame drive devices, trimming and plastering hangers, trimming and plastering devices and trimming and plastering drive devices. The main frame is installed on the main frame drive devices and can move forwards, backwards, upwards and downwards. The multiple trimming and plastering hangers are installed on the main frame. The trimming and plastering devices comprise trimming and plastering rotary shafts and trimming and plastering tools. The trimming and plastering rotary shafts are installed on the trimming and plastering hangers and driven by the trimming and plastering drive devices to rotate. The multiple trimming and plastering tools used for trimming and plastering the concrete face are installed on the trimming and plastering rotary shafts. By the adoption of the automatic panel trimming and plastering machine for the full concrete faced rockfill dam concrete panel construction line, design is reasonable, full-line mechanical construction performed along a slope upwards of the trimming and plastering process of the rockfill dam panel concrete sliding die release concrete face is achieved, standard and mechanical operation of the whole trimming and plastering process is achieved, and the concrete face trimming and plastering quality and efficiency of the machine are remarkably improved.

Description

technical field [0001] The invention relates to a mechanical device for smoothing and smoothing the concrete surface of a rockfill dam after the concrete sliding form construction of the face of the face is demoulded, in particular to an automatic face repairing machine for the entire line of the concrete face of the face rockfill dam. Background technique [0002] Concrete surface repair and plastering after demoulding is a very important link in concrete slipform pouring of face rockfill dams. The construction technology currently used in China and the shortcomings of this technology are described as follows: [0003] 1. Set a plastering platform behind the installed flat-plate sliding form, and the plastering platform and the sliding form move together during the construction of the panel concrete sliding form; [0004] 2. During the construction of the slip form, the surface of the concrete is finished by manual plastering on the plastering platform at the back of the fo...

AI Technical Summary

Problems solved by technology

[0007] 1. Concrete panel construction quality defects: more manpower is required to plaster the surface behind the panel plate sliding form, but the quality of manual repair is not easy to guarantee. After construction, the concrete surface is rough, the finish is very low, and unevenness often occurs. This is manual construction. Quality defects that are not easy to solve;

[0008] 2. The problem of construction progress: the sliding form plastering process consumes a lot of labor, and the construction progress is affected by the labor intensity of the personnel; the whole process is manual operation, and the sliding form shifting speed is too slow;

[0009] 3. Construction safety issues: The sliding form construction plastering process must be manually operated repeatedly, the material handling on the sliding form body is complicated, the staff walks back and forth frequently, and there are many safety hazards;

[0010] 4. The hand-held disc-type troweling machine cannot realize the construction of the whole line section (the entire width of the warehouse is 12m to 15m) in the concrete pouring warehouse of the rockfill face dam, because the slope of the rockfill dam face is between 1:1.5 Above, it is difficult for personnel to stand stably, the potential safety hazard is relatively large, and the quality and safety are not easy to guarantee;

[0011] 5. At present, the mechanical troweling machine used on large canal slopes at home and abroad is still an improved version of the disc troweling machine. Although its trowel is changed from manual push to mechanical pull, its repair on the slope The plastering surface is composed of small strips going up the slope. This small strip is continuously increasing and expanding along the central axis of the channel (walking on the frame as a whole), and the small strips going up the slope are still relying on a small disc trowel. (the disc trowel slides on the frame), so it still cannot realize the construction along the entire line (the entire width of the warehouse is 12m to 15m) on the face plate of the rockfill dam, and it has not been seen so far. Reports on the use of mechanical troweling machines or other mechanical troweling machines on large canal slopes to realize the construction of the entire line in the bunkers where the face of the rockfill dam goes up the slope

[0012] To sum up, the traditional technology of concrete surface repair and plastering after demoulding of rockfill dam slab concrete slipform pouring construction can no longer meet the current requirements for slab construction tasks, and cannot achieve the purpose of high-quality, fast and safe construction of rockfill dam slab concrete pouring. With the rapid development of water conservancy, hydropower and infrastructure construction, traditional technology has been unable to solve a series of increasingly prominent technical problems such as construction period, quality and safety in the concrete pouring construction of face rockfill dams.
