Embodiment Construction
[0020] The summary of the invention has described the specific implementation manner of the present invention in detail, does not repeat here, needs to explain as follows: 1. see figure 1 , figure 2 , under normal circumstances, the truncated concrete pile 12 needs to keep the pile main reinforcement 13 with a length of about 500 mm without cutting it. This section of steel reinforcement needs to be embedded in the pile cap that will be poured later. The concrete protective layer (concrete other than the pile main reinforcement) exposes the pile main reinforcement 13, and then the upper pile core concrete is excised from the pile cutting plane 14. The present invention designs 3 hydraulic shears up and down to achieve the purpose of peeling off the concrete protection layer. The concrete protective layer is only 50 mm thick, and the force applied by the hydraulic system 2 does not need to be very large, so the hydraulic shear B11 does not need to design a hydraulic system, an...

The invention relates to a size-adjustable hydraulic shear for cutting a concrete pile head. The hydraulic shear is mainly used for cutting the concrete pile head in the field of constructional engineering. The hydraulic shear mainly comprises a hydraulic shear body A 1, a pin 5, a shaft 6, a hydraulic shear body B 11, a lifting chain 16, a rotary disc 17 and a lifting hook 18. The main working principle of the hydraulic shear is characterized in that 3 hydraulic shears are started to strip a concrete protecting layer, the lower hydraulic shear body A 1 is then started, the pushing drill rod 4 of the hydraulic shear body A 1 continuously pushes into pile core concrete, the annular cutter 3 of the hydraulic shear body A 1 starts working to cut off the uneven concrete protecting layer at a cutting pile plane 14, the pile core concrete above the cutting pile plane 14 is forced to move upwardly, and the concrete above and below the cutting pile plane 14 is separated.
Description
technical field [0001] The invention is mainly used for cutting concrete pile heads in the field of construction engineering. Background technique [0002] The currently authorized and applied for concrete pile cutting equipment patents do not consider the protection of the main reinforcement of the pile, and the plane of the pile cutting is uneven, requiring manual secondary repairs, and the equipment is complicated, and the manufacturing cost and maintenance cost are high. Contents of the invention [0003] The present invention solves the above-mentioned problems. It does not damage the stressed main tendon of the pile and the plane of the truncated pile is neat, no manual secondary trimming is required, and the equipment is simple, and the manufacturing cost and maintenance cost are low; the present invention mainly includes hydraulic shears A ( 1), pin rod (5), shaft (6), hydraulic shear B (11), lifting chain (16), turntable (17), hook (18), hydraulic shear C (25); hy...
