Description

Technical Field

[0001] The invention relates to the technical field of tunnel construction, and in particular to a concrete vibrating device and a trolley containing the concrete vibrating device. Background Art

[0002] During the concrete pouring process, in order to prevent the concrete from becoming hollow, uneven, honeycombed, or loose, a vibrating device must be used to vibrate the concrete.

[0003] When using large formwork to cast a concrete structure with a certain thickness (such as the second lining of a tunnel), it is generally necessary to install an attached flat plate vibrator on the formwork to vibrate the concrete on the surface of the formwork and use a handheld vibrator to vibrate the concrete deeply through the window opened on the formwork. Since the vibration depth of the attached flat plate vibrator is limited, the vibration depth of the handheld vibrator is sufficient but the vibration range is limited, resulting in many places (such as the vault position) not being effectively vibrated in depth. Therefore, most people use an inserted vibrator installed on the formwork to compensate for the problem of insufficient vibration depth.

[0004] When using an inserted vibrator for vibration, the internal steel mesh of the lining is blocked by the formwork and cannot be seen. It is not possible to see whether the vibrator rod interferes with the steel mesh and other obstacles during the insertion process. If there is interference, there are two risks (high risks) during the insertion of the vibrator: (1) the steel mesh structure is damaged and the lining quality cannot be guaranteed; (2) the driving mechanism of the vibrator or the formwork structure in the trolley is damaged due to obstacles.

[0005] Therefore, it is of great significance to design a vibrating device with a simple structure, which can effectively avoid the steel mesh, has a good vibration effect and is easy to operate. Summary of the invention

[0021] Preferably in the above technical solution, a protective cover for protecting the vibrating device is provided on the outer side of the driving mechanism.

[0022] The application of the technical solution of the present invention has the following beneficial effects:

[0023] (1) The concrete vibrating device of the present invention comprises a vibrating device, a rotating assembly and a mounting frame support. The vibrating device is used to vibrate concrete and can be rotatably arranged on the mounting frame support through the rotating assembly. The effect is: the structure is simple; the rotating assembly drives the vibrating device to rotate, and the relative position of the vibrating device and the mounting frame support is adjusted by the rotating assembly to achieve vibration of different positions of the concrete, which can effectively avoid the steel mesh and is suitable for lining construction with a steel mesh inside. It can not only efficiently vibrate the concrete, but also will not cause damage to the formwork or the vibrating device, and the vibration effect is good and the operation is convenient.

[0024] (2) The structure of the rotating assembly in the present invention is varied, and it is sufficient to realize the rotation of the vibrating device, so as to facilitate the control of the vibrating device to avoid the steel mesh; the preferred rotating assembly includes a rotating support frame, a rotating power member and a turntable, and the design of the turntable can meet the requirements of stable and rapid rotation; the rotating speed and rotation angle of the turntable are controlled by the rotating power member, which is conducive to accurately controlling the position of the vibrating device and achieving high-quality vibration (good vibration effect). The rotating power member can be a component that is easy to operate manually (such as a combination of a rotating rod and a rod sleeve), or it can be a component that uses a telescopic oil cylinder or a telescopic air cylinder to achieve semi-mechanized control.

[0025] (3) The mounting bracket in the present invention is an annular structure, and a first step-shaped portion is provided on the inner wall thereof, and a second step-shaped portion matching the first step-shaped portion is provided on the outer periphery of the turntable (the structures of the first step-shaped portion and the second step-shaped portion can be set according to actual conditions). The mounting bracket and the turntable are rotatably connected through the cooperation of the first step-shaped portion and the second step-shaped portion, the turntable has good rotation stability, and the components are easy to process. The first step-shaped portion and / or the second step-shaped portion are provided with a groove for accommodating lubricating oil, so as to ensure lubrication between the mounting bracket and the turntable and ensure the smooth rotation of the turntable.

[0026] (4) In the present invention, a through hole is provided on the turntable, and the vibrating device can be inserted into the through hole, and the center of the through hole is staggered with the center of the turntable (that is, the vibrating device and the turntable are eccentrically arranged), which is beneficial to driving the vibrating device to effectively avoid the steel mesh when the turntable is rotated, and further facilitates the vibration of concrete. Sealing rings are respectively provided between the turntable and the mounting bracket and between the vibrating device and the turntable to ensure the sealing of the entire trolley template and prevent leakage of slurry.

[0027] (5) The present invention also provides a pressure plate, which forms a receiving cavity for receiving the turntable with the mounting bracket, and the pressure plate and the mounting bracket are combined to limit the position of the turntable, so as to ensure that the turntable is fixed when the turntable can rotate.

[0028] (6) The present invention also includes a limit member for limiting the position of the turntable. The position of the limit member can be selected according to actual needs to limit the turntable. In particular, after the turntable is rotated into place, the turntable is fixedly limited when the vibrating device is vibrating. The rotation of the vibrating device (high-speed rotation) is harmful to people and equipment, thereby improving construction safety performance.

[0029] (7) The present invention also includes a detector for detecting whether there are foreign objects in the concrete, which can quickly determine whether the rotating vibrating device can avoid the steel mesh, thereby improving work efficiency. If there is no foreign object detector (such as an infrared device, etc.), the vibrating device can only determine whether it has effectively avoided the steel mesh by the specific position where it can be inserted into the concrete. If there is a steel mesh, it will continue to rotate to avoid it; if there is no steel mesh, it will continue to vibrate.

[0030] (8) The vibrating device of the present invention can adopt a combination of a driving mechanism and a vibrating rod, the vibrating rod is used to vibrate the concrete, and the driving mechanism is connected to the vibrating rod to provide power for the vibrating rod to extend and retract. A protective cover can also be set on the outside of the driving mechanism to protect the vibrating device. The driving mechanism can adopt structures such as a screw slide, a rack and pinion, etc., which can drive the vibrating rod to be accurately extended and retracted. In addition, the vibrating rod has or is equipped with a power source for vibrating, such as a power source for high-speed rotation (the speed is determined according to actual needs), and the prior art can be referred to. The protective cover can adopt structures such as a bending plate, a folding protective cover, etc., which can be selected according to actual conditions. It is preferred that the driving mechanism and the vibrating rod are installed side by side to effectively save installation space.

The trolley may also be provided with a walking mechanism, a transverse movement mechanism, a lifting mechanism, etc. with reference to the existing lining trolley, so as to facilitate lining construction.
