Description

Technical Field

[0001] This utility model relates to the field of acetylene filling technology, specifically to an acetylene safety filling device. Background Technology

[0002] Acetylene is an important industrial gas with wide applications in many fields, such as medical, chemical, and aerospace. Acetylene filling is the process of safely and accurately injecting acetylene from a storage container into a tank to be filled.

[0003] However, existing acetylene filling equipment has some shortcomings. In terms of safety, existing filling equipment often lacks effective protective measures. In the event of an accident during the filling process, such as an acetylene leak or a tank rupture and explosion, the lives of operators may be seriously threatened. Furthermore, existing filling equipment is inadequate in terms of tank fixation and positioning. The tank may shake or shift during filling, affecting the accuracy and stability of the filling process, and may even lead to filling accidents.

[0004] Therefore, this solution proposes an acetylene safety filling device to solve the above problems. Utility Model Content

[0005] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide an acetylene safety filling device.

[0006] To achieve the aforementioned objective, the technical solution of this utility model is implemented as follows: An acetylene safety filling device includes a base, a tank positioning seat is provided at the center of the top of the base, a gantry frame is also installed above the base, a stepping cylinder is installed at the center of the top of the gantry frame, a cylindrical protective cover is installed at the telescopic end of the stepping cylinder, a filling gun is installed at the center of the top of the cylindrical protective cover, the tank positioning seat includes a placement platform installed at the center of the top of the base, two side clamping assemblies are provided at the top of the placement platform, a transverse mounting groove is provided inside the placement platform, and clamping drive components for synchronously driving the side clamping assemblies on both sides to clamp the bottom sides of the tank towards the center are installed inside the transverse mounting groove.

[0007] Preferably, the side clamp assembly specifically includes the following structure:

[0008] A mounting base;

[0009] An arc-shaped clamping plate fixed to the inside of the mounting base.

[0010] Preferably, a flexible padding layer is provided on the inner side of the arc-shaped clamping plate.

[0011] Preferably, the clamping drive specifically includes the following structure:

[0012] A dual-shaft geared motor installed in the center of the horizontal mounting slot;

[0013] The drive screws are respectively connected to the output ends on both sides of the dual-axis geared motor;

[0014] Screw sleeves are threaded onto the drive screws on both sides, and the top walls of the screw sleeves on both sides are connected to the bottom of the side clamping assemblies on both sides.

[0015] Preferably, the filling gun has an inlet pipe connected to its side, which leads to the outside of the cylindrical protective cover and is connected to the output end of the high-pressure acetylene storage tank.

[0016] Preferably, guide posts are provided on both the left and right sides of the top of the cylindrical protective cover, and the top ends of the guide posts slide out of the top of the gantry frame.

[0017] The beneficial effects of this utility model are reflected in:

[0018] Improve security:

[0019] The device features a vertically movable cylindrical protective cover that descends to the top of the tank positioning seat during the filling process, enclosing the acetylene tank inside. This design effectively prevents injuries caused by accidents during filling, such as the dangers of acetylene leakage, providing reliable safety for operators.

[0020] Enhanced stability:

[0021] The tank positioning base further enhances stability during filling. The placement platform provides a stable platform for the tank, while the side clamping components on both sides can clamp the tank from both sides, ensuring that the tank will not shake or shift during the filling process.

[0022] The arc-shaped clamping plate in the side clamping assembly is adapted to the shape of the tank, which can better fit the tank for clamping. The flexible pad on the inner side can not only protect the surface of the tank from scratches, but also increase the friction and stability of the clamping, so that the tank remains stable during the filling process.

[0023] Precise control of the filling process:

[0024] The stepping cylinder installed at the center of the top of the gantry can precisely control the telescopic movement, thereby driving the lifting and lowering of the cylindrical protective cover to achieve precise protection during the liquid filling process.

[0025] The filling gun, installed at the top center of the cylindrical protective cover, is connected to the output end of the high-pressure acetylene storage tank via a side-mounted inlet pipe, enabling accurate injection of acetylene into the tank and ensuring the accuracy and reliability of the filling process.

[0026] In summary, this acetylene safety filling device, through its vertically movable cylindrical protective cover and tank positioning seat design, effectively improves the safety and stability of the filling process. The design concept and functional characteristics of this device make it of significant application value and promotional importance in the field of acetylene filling, helping to reduce the occurrence of safety accidents, improve work efficiency, and ensure the safety of personnel and equipment.
