Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of building engineering construction equipment, and specifically relates to a multi-pile position construction equipment. BACKGROUND

[0002] In the process of foundation reinforcement construction, vibroflotation and column hammer ramming expansion are two common construction methods. Vibroflotation mainly vibrates and impacts the soil layer through a vibrator to make the surrounding soil dense and fill appropriate materials to improve the bearing capacity of the foundation. The column hammer ramming expansion method is to improve the compaction degree of the foundation by high-frequency tamping of fillers, which is suitable for construction scenes requiring higher compaction degree.

[0003] Currently, in actual engineering, vibroflotation construction and column hammer ramming expansion construction often need to use different equipment for operation. For example, vibroflotation construction usually uses special vibroflotation equipment, while column hammer ramming expansion construction needs independent ramming expansion equipment. This equipment separation construction method has the following problems:

[0004] 1. Low equipment utilization and high construction cost: Since vibroflotation construction and column hammer ramming expansion construction require different equipment, the idle rate of the equipment is high, and the equipment purchase and maintenance cost is increased, which increases the overall construction cost.

[0005] 2. Low construction efficiency: The existing construction method usually needs additional machinery and manual operation for equipment replacement and adjustment after completing vibroflotation construction, which increases the time cost of construction.

[0006] 3. Complex operation conversion, affecting project progress: When switching from vibroflotation construction to column hammer ramming expansion construction, the existing equipment needs to be disassembled and adjusted complicatedly, the construction process is not continuous enough, which affects the construction efficiency and quality.

[0007] 4. Low filling material supplement efficiency: In the process of column hammer ramming expansion construction, the supplement of fillers usually depends on manual operation or independent machinery, and the filling process is discontinuous, which affects the construction quality and compaction degree.

A winch is fixedly installed on the tracked machine body 1. The winch is an electric winch with a rated tensile force of not less than 50kN to ensure the stability and reliability of the wire rope during lifting and laying. The drive motor of the winch has a rated power of 15kW and is equipped with an automatic overload protection device to improve safety.

[0033] The equipment also includes a main wire rope 3 and multiple auxiliary wire ropes 5. The main wire rope 3 is made of high-strength galvanized steel wire rope with a diameter of not less than 16mm to ensure good wear resistance and fatigue resistance during long-term construction. The upper ends of the multiple auxiliary wire ropes 5 are all fixedly connected to the main wire rope 3 and are evenly distributed in a parallel arrangement to ensure that the multiple auxiliary wire ropes 5 are evenly stressed and prevent uneven loading. The lower end of the main wire rope 3 is connected to a winch, which controls the unwinding and winding of the main wire rope 3, thereby synchronously controlling the lifting and lowering of the multiple auxiliary wire ropes 5.

[0034] The upper end of the support frame 2 is provided with a guide frame 4 for uniformly separating and guiding the plurality of auxiliary steel wire ropes 5.

A plurality of first pulleys 42 are fixed at the end corners of the fixed frame 41 facing the main steel wire rope 3. The first pulley 42 is installed in a rotatable support structure to ensure that the auxiliary steel wire rope 5 can be flexibly adjusted in angle when passing through the pulley, thereby reducing the stress damage of the steel wire rope.

[0036] As shown in Figure 1 , the support frame 2 is slidably provided with a positioning frame 8 for positioning and guiding the column hammer 7. The material of the positioning frame 8 is high-strength alloy steel, and wear-resistant bushings are added at key positions to reduce sliding friction. The side of the support frame 2 away from the track body 1 is fixed with a hydraulic rod 6 for driving the positioning frame 8 to lift and lower. The rated thrust of the hydraulic rod 6 is not less than 80 kN, which can ensure stable and reliable lifting or lowering. The stroke length of the hydraulic rod 6 is not less than 1.5 m to meet the needs of different construction depths. The hydraulic system is provided with a hydraulic control valve group, which can control the lifting speed of the positioning frame 8 by accurately adjusting the oil pressure, thereby realizing precise construction of the column hammer 7 or the vibrator 9.
