Description

TECHNICAL FIELD

[0001] The utility model belongs to civil engineering technical field, concretely relates to a soft ground vibroflotation system based on excavator drive. BACKGROUND

[0002] The soft ground vibroflotation reinforcement technology belongs to the civil engineering field, is widely used in foundation engineering construction, and is used for improving the bearing capacity of soft ground and reducing ground settlement.In traditional construction, the vibroflotation device usually needs to be operated by means of a crawler crane or a truck crane, the vibroflotation device is connected to the jib by a steel wire rope, and reinforcement work is completed by cooperating with an external power source.However, this traditional construction method has many limitations and problems.

[0003] At present, the soft ground vibroflotation reinforcement construction usually needs to rent a crawler crane or a truck crane to lift and position the vibroflotation device.For example, the rental cost of a 25-ton crane is about 1600 yuan / class.In addition, the power source of the vibroflotation device is usually a hydraulic power pack, a generator or a temporary power cable connection for power supply.Although power grid power supply has relatively low comprehensive cost, the use of long-distance cable or hydraulic oil pipe in the construction site will affect the construction convenience, and the laying and management of the line increase the additional work burden.

[0004] In the connection of the vibroflotation device and the hoisting equipment, the steel wire rope is easy to be wound due to the torque effect in the vibroflotation operation, which reduces the operation safety and increases the safety hidden danger in the construction process.Usually, a person needs to be arranged to pull the anti-twist rod of the vibroflotation device through a long rope, and anti-twist plates are welded on both sides of the lower end of the vibroflotation device to reduce the torsion of the vibroflotation device in the operation process.However, this method not only increases the complexity of manual operation, but also affects the construction efficiency.

[0005] In addition, since the traditional hoisting equipment uses a steel wire rope for soft connection, when only relying on the self-weight of the vibroflotation device to complete the down-penetration operation in short pile construction, the vibroflotation effect is limited by the weight of the equipment, which cannot meet some construction requirements. UTILITY MODEL CONTENTS

[0006] In view of the problems existing in the prior art, the purpose of the utility model is to provide a soft ground vibroflotation device system based on excavator drive, which can realize the optimization of the connection mode and operation process of the vibroflotation device, improve the construction safety and efficiency, reduce the dependence on external equipment, and better meet the actual needs of soft ground reinforcement construction.

[0007] To achieve the above purpose, the utility model provides the following technical scheme:

[0008] A soft ground vibroflotation device system based on excavator drive, comprising a machine body, a machine arm is arranged on the machine body, a connecting piece is connected to the movable end of the machine arm, and a vibroflotation device body is connected to the bottom of the connecting piece.

[0009] The connecting piece comprises a top base and a pin joint column, and the top base is connected to the movable end of the machine arm through the pin joint column;

[0010] The bottom of the top base is connected with a bottom base, and the bottom base is connected to the vibrator body through bolts.

[0011] Further, the top base comprises a bottom plate, and symmetrical side plates are fixedly connected to the upper end face of the bottom plate, and pin joint holes are formed through the side faces of the side plates.

[0012] The movable end of the machine arm is located in the side plates, and the pin joint column penetrates into the pin joint holes.

[0013] Further, the side plates and the bottom plate are fixedly connected with a reinforcing plate.

[0014] Further, the bottom base comprises a connecting plate connected to the bottom plate.

[0015] The upper end face of the bottom plate is symmetrically provided with a first connecting hole, and the upper end face of the connecting plate is provided with a second connecting hole corresponding to the first connecting hole.

[0016] Further, the lower end face of the connecting plate is fixedly connected with a control bin, the control bin is fixedly connected with a valve block outside the side, and a hydraulic oil hole is formed through the side face of the valve block.

[0017] Further, the bottom of the control bin is fixedly connected with a bolt joint, and lock grooves are formed at equal intervals around the central axis outside the bolt joint, and a bolt hole is formed through the bottom of the lock grooves.

[0018] Further, a mounting process hole is formed through the center of the upper end face of the connecting plate.

[0019] Compared with the prior art, the utility model has the beneficial effects that:

[0020] Firstly, the traditional soft foundation vibroflotation reinforcement technology often relies on large lifting equipment, resulting in high construction cost and complex operation. However, the present application can realize accurate control of the vibrator body by using an excavator as a driving device, thereby reducing the dependence on traditional lifting equipment. The machine arm on the machine body realizes flexible movement in multiple directions through a hydraulic control system, can freely adjust the position of the vibrator according to the site conditions, significantly reduces the demand for lifting equipment on the construction site, thereby effectively reducing the equipment rental cost and reducing the construction cost.

[0021] Secondly, the steel wire rope connection mode is often used in the prior art to fix the vibroflot, which is easy to be wound by vibration and has certain safety hazards. The application optimizes the connection mode, connects the top seat and the side plate by the pin joint column, avoids the winding risk of the steel wire rope, and improves the stability and safety of the equipment during the vibroflotation operation. The pin joint column is made of hardened steel material, which not only improves the wear resistance, but also ensures the firmness of the connection, avoids the problems such as loosening and falling of the vibroflot during the operation, and greatly improves the safety of the operation.

[0022] Furthermore, in the prior art, the self-weight of the vibroflot is insufficient to complete the effective reinforcement of the short pile, which limits the operation efficiency. The base of the application is connected with the vibroflot body by bolts, so that the vibroflot body can be stably fixed on the connecting piece, and through the precise control of the arm, the vibroflot can be operated at different pile foundation depths, which can better complete the short pile construction and speed up the process of foundation reinforcement, and ensure the construction quality.

[0023] Finally, the electric control system of the traditional equipment is often exposed to the external environment and is easy to be affected by factors such as moisture and dust, which leads to frequent equipment failures. In order to solve this problem, the control bin is fixed at the lower end of the connecting plate, and the control system is effectively protected through sealing design. The electrical control equipment is integrated in the control bin, and the electrical connection between the valve block and the control bin inside provides stable and reliable power supply and control signals for the system. The design ensures that the control system can stably operate in harsh construction environment, reduces the occurrence of equipment maintenance and failure, and improves the overall reliability of the system.
