Description

Technical Field

[0001] The utility model relates to the technical field of air separation cold box maintenance, and more specifically, to an auxiliary dismantling device for an external scaffolding of an air separation cold box. Background Art

[0002] The air separation cold box external scaffolding auxiliary removal device is a mechanical device or tool combination specially used to assist in the removal of the external scaffolding of the air separation cold box. The air separation cold box is a key component in the air separation unit, used to cool and liquefy air for subsequent separation and extraction. Due to the complex structure and large size of the cold box, scaffolding is often required on its outside for installation, maintenance or removal.

[0003] Among them, patent number CN202121022776.5 in the prior art discloses a scaffolding dismantling device. In actual use, relying on a longer lever arm, the operator manually presses the first clamp body and the second clamp body so that the first clamp seat and the second clamp seat abut against each other, and the steel pipe constituting the scaffolding is placed between the first clamp seat and the second clamp seat. The operator can use this device to quickly disassemble and assemble the scaffolding. However, this prior art requires the user to press each lever arm with his hand when using it, which is more laborious and easy to cause hand discomfort, affecting the disassembly efficiency. Therefore, it needs further improvement. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides an auxiliary dismantling device for an external scaffolding of an air separation cold box, aiming to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an auxiliary dismantling device for an external scaffolding of an air-separation cold box, comprising a base for support, on which a dismantling assembly is arranged; the dismantling assembly comprises a top rod arranged at one end of the base, one end of the top rod is movably connected to a first axle pin through an axle pin, and one side of the first axle pin is provided with a second axle pin movably connected to the top rod through an axle pin; one end of the first axle pin is movably connected to a first clamping rod through an axis, and one end of the second axle pin is movably connected to a second clamping rod through an axle pin; one end of the first clamping rod and the second clamping rod are both provided with clamping blocks, the two clamping blocks are respectively detachably connected to the first clamping rod and the second clamping rod, and an anti-slip strip is provided on the outer side of each clamping block.

[0006] It can be seen that in the above technical solution, the first axial pin member and the second axial pin member are driven to move by the displacement of the push rod. When the first axial pin member and the second axial pin member are displaced, the first clamp rod and the second clamp rod are driven to rotate by the traction force when the push rod is displaced, thereby making the clamping blocks on the first clamp rod and the second clamp rod close to each other, making it easy to get stuck on the bolts fixing the scaffolding, thereby facilitating its disassembly.

[0007] Optionally, in a possible implementation, an electric push rod for driving the push rod to move is provided at one end of the push rod, an upper cover is provided at the top of the base and located outside the first shaft pin and the second shaft pin, a first locking sleeve is provided at one end of the base, a second locking sleeve is provided at one end of the upper cover, the upper cover is detachably connected to the base, the second locking sleeve and the first locking sleeve are both sleeved on the electric push rod and threadedly connected to the electric push rod, a handle for holding is provided on the base, and one end of the first clamping rod and the second clamping rod are both movably connected to a limiting cylinder installed on the base through a shaft pin;

[0008] It can be seen that in the above technical solution, the displacement of the push rod is driven by the electric push rod, which makes it easy to connect various structures. The setting of the handle makes it convenient for the user to hold the handle with one hand and the electric push rod with the other hand, thereby improving the stability during disassembly. The setting of the first locking sleeve and the second locking sleeve facilitates the positioning of the electric push rod during installation, thereby ensuring the stability of the electric push rod during installation.

[0009] Technical effects and advantages of the utility model:

[0010] By setting up the dismantling assembly, the overall design is simple and the structure is reasonable. Through the corresponding coordinated use of various structures, the displacement of the top rod drives the displacement of the first shaft pin and the second shaft pin. When the first shaft pin and the second shaft pin are displaced, the first clamping rod and the second clamping rod are driven to rotate by the traction force when the top rod is displaced, and then the clamping blocks on the first clamping rod and the second clamping rod are made close to each other, which is easy to be clamped on the bolts fixing the scaffolding, so as to facilitate its disassembly. At the same time, it is also used for the device to quickly cover the scaffolding bolts.

[0011] At the same time, the displacement of the push rod is driven by the electric push rod, which makes it easy to connect various structures. The setting of the handle makes it convenient for the user to hold the handle with one hand and the electric push rod with the other hand, thereby improving stability during disassembly.
