The construction of the secondary lining of the tunnel ensures the permanent stability, safety and beauty of the tunnel during the operation process, and is also an engineering measure as a safety reserve.

[0003] In the construction of the secondary lining of railways, highways, subways and water conservancy tunnels, formwork trolleys are usually used. The formwork trolley is composed of a gantry, formwork, traveling, hydraulic, electrical and vibrators, etc. Among them, the ramming of the top arch cannot be operated manually by inserting, and only relying on the flat attached vibrator is prone to defects such as incomplete vibration and cavities, and it needs to be vibrated multiple times during tunnel construction. The loading and unloading of the vibrator will consume a lot of time.

[0004] Therefore, there is an urgent need for a vibrator that is convenient to connect and easy to insert into the top arch. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a quick-connect plug-in vibrator for the top arch of a formwork trolley to solve the above problems.

[0006] To achieve the above object, the utility model provides a quick-connect plug-in vibrator for the top arch of a formwork trolley, which includes a bracket. The top of the bracket is open. An electric push rod is arranged inside the bracket. The top of the electric push rod is provided with a vibrating rod, and the vibrating rod is connected to the push rod of the electric push rod. A support plate is arranged on the top of the bracket. A plurality of fixing plates are arranged on the support plate, and the plurality of fixing plates are evenly distributed around the bracket. Fixing holes are arranged on the fixing plates;

[0007] Around the pouring window of the top arch of the formwork trolley, there are connecting plates corresponding to the fixing plates. Connecting holes are arranged on the connecting plates, and a pin shaft is inserted into the connecting holes. The diameter of the pin shaft is adapted to the connecting holes and the fixing holes.

[0008] Furthermore, a hinge seat is arranged on the top of the electric push rod. The hinge seat is rotatably connected to the push rod of the electric push rod, and the vibrating rod is arranged on the hinge seat.

[0009] Furthermore, a clamping plate is arranged on the top of the bracket. The support plate is arranged on the clamping plate, and the support plate is connected to the clamping plate by bolts.

[0010] Furthermore, the top of the hinge seat is cylindrical and has the same diameter as the vibrating rod, and the hinge seat is connected to the vibrating rod through a pipe clamp.

[0011] The utility model has the following beneficial effects:

[0012] The utility model realizes the quick connection between the vibrator and the crown arch through a pin shaft, a connecting plate and a fixing plate, which is convenient for the adjustment and multiple use of the vibrator, and realizes the insertion of the vibrating rod through an electric push rod, improves the construction efficiency and reduces the personnel burden.

[0016] To achieve the above-mentioned purpose and effect, the technical means and structure adopted by the utility model are described in detail in terms of its features and functions in combination with the attached drawings for the preferred embodiments of the utility model.

[0017] As shown in the atta Figure 1-2 As shown in the figure, the utility model provides a quick-connection plug-in vibrator for the crown arch of a formwork trolley, which includes a bracket 1. The bracket 1 is U-shaped, and an electric push rod 2 is arranged inside the bracket 1. The sleeve of the electric push rod 2 is fixedly connected to the inner wall of the bracket 1. A motor for driving the electric push rod 2 is arranged on one side of the bottom of the electric push rod 2. A vibrating rod 3 is arranged on the push rod of the electric push rod 2, so as to change the position of the vibrating rod 3 through the telescopic movement of the electric push rod 2. A support plate 4 surrounding the bracket 1 is arranged on the top of the bracket 1. A plurality of fixing plates 5 are evenly distributed around the bracket 1 on the support plate 4, and fixing holes are arranged on the fixing plates 5;

[0018] A plurality of connecting plates 6 corresponding to the fixing plates 5 are arranged around the pouring window of the crown arch of the formwork trolley. Connecting holes are arranged on the connecting plates 6, and a pin shaft 7 is inserted into the connecting holes. The diameter of the pin shaft 7 is adapted to the connecting holes and the fixing holes.

[0019] During actual use, the staff first lift the bracket 1 to align the fixed plate 5 on the bracket 1 with the connecting plate 6 around the pouring window. Then, the pin shafts 7 on multiple connecting holes are sequentially inserted into the fixing holes, so that the bracket 1 is relatively fixed to the formwork trolley. Next, the electric push rod 2 is started, and the push rod on the electric push rod 2 extends, so that the vibrating rod 3 extends into the crown arch from the pouring window. Finally, the vibrating rod 3 is started for vibration.

[0020] When it is necessary to adjust the vibration position or end the vibration, it is only necessary to stop the vibrating rod 3 and retract the push rod on the electric push rod 2, and then pull out the pin shaft 7 out of the fixing hole, and the rapid disassembly of the device can be realized.

[0021] In another embodiment, a hinge seat 8 is provided at the top of the electric push rod 2. The hinge seat 8 is rotatably connected to the push rod of the electric push rod 2. The vibrating rod 3 is a high-frequency built-in vibrating rod, and the vibrating head of the vibrating rod 3 is arranged on the hinge seat 8 and connected to the hinge seat 8 through a pipe clamp 9. In this way, during vibration, the staff can adjust the angle of the vibrating head to ensure the vibration effect.

[0022] In another embodiment, a clamping plate surrounding the bracket 1 is provided at the top of the bracket 1. The support plate 4 is arranged on the clamping plate and connected to the clamping plate by bolts. Thus, in different projects, different support plates 4 can be replaced according to the actual situation, so that the fixed plate 5 on the device can adapt to the connecting plates 6 around the pouring windows under different working conditions.

[0023] The above are only the preferred embodiments of the present utility model, not all embodiments. Anyone should know that the structural changes made under the inspiration of the present utility model, as long as they have the same or similar technical solutions as the present utility model, all belong to the protection scope of the present utility model.
