Description

Technical Field

[0001] This utility model relates to the technical field of special gas cabinet equipment, and in particular to a cylinder replacement device for a special gas cabinet and a special gas cabinet. Background Technology

[0002] Specialty gas holders are critical equipment used for storing and transporting special gases (such as high-purity, toxic, or flammable gases), and are widely used in precision manufacturing industries such as semiconductors and photovoltaics. Their core function is to achieve a stable supply of gas from cylinders through a closed system, while ensuring operational safety and equipment durability.

[0003] The existing method of changing gas cylinders in special gas holders requires personnel to remove empty cylinders from inside the equipment and then manually move full cylinders to a designated location through narrow passages. Furthermore, the movement of empty / full cylinders requires multiple angle adjustments to complete the movement path in and out of the cabinet.

[0004] However, the existing operating method has the following drawbacks:

[0005] 1. Operating inside the equipment is in a confined space, which can lead to insufficient operating space and inconvenience.

[0006] 2. Replacing the gas cylinder will damage the sheet metal structure at the bottom of the special gas cabinet, causing paint peeling, etc. After the paint peels off, there is a risk of rust after long-term use of the equipment.

[0007] 3. During the replacement of the gas cylinder, due to the relatively tall size of the cylinder, improper operation may cause collisions and damage to the components on the panel inside the special gas cabinet.

[0008] Currently, no effective solutions have been proposed for the problems of inconvenient replacement operations and the potential damage to the special gas holder during the replacement process in related technologies. Utility Model Content

[0114] The cylinder and bracket 110 can be moved back and forth by the cooperation of the lifting slide rail 310 and the lifting slider 320. In addition, the telescopic buffer 350 arranged in the first telescopic connector 330 and the second telescopic connector 340 can make the cylinder and bracket 110 descend slowly, thereby preventing the cylinder from shaking or even tipping over. At the same time, during the slow descent of the cylinder and bracket 110, the cooperation of the lifting slide rail 310 and the lifting slider 320 can prevent the cylinder from shaking randomly during the landing process.

[0115] After the gas cylinder and bracket 110 are placed on the ground, the staff opens the clamp and removes the gas cylinder from the bracket 110. Then, the full gas cylinder is placed on the bracket 110 and fixed to the bracket 110 with the clamp.

[0116] Finally, the staff lifted the bracket 110 upwards, causing it to leave the ground, and then pushed it to move it into the interior of the special gas cabinet, thus replacing the gas cylinder.

[0117] The advantages of this embodiment are that the cylinder support component is connected to the special gas cabinet through horizontal and vertical moving components, allowing the operator to pull the cylinder support component out of the special gas cabinet, thereby solving the problems of insufficient space and inconvenience in operation inside the special gas cabinet; in addition, the vertical moving component allows the cylinder support component to descend or rise slowly, thereby preventing the cylinder from shaking or even tipping over during the lifting and lowering process; furthermore, during the slow descent of the cylinder and cylinder support component, the vertical moving component can prevent the cylinder from shaking randomly when it lands.

[0118] Example 2

The fixed bracket is installed on the inner bottom wall of the special gas cabinet by means of welding, riveting, or bolting; the first end of the rotating rod is rotatably connected to the fixed bracket by means of bearings, etc., and the second end of the rotating rod is connected to the locking member 420.

[0125] It should be noted that the rotating connector 410 includes, but is not limited to, the adapter frame.

[0126] In some of these embodiments, the rotating connector 410 includes, but is not limited to, a rotating shaft.

[0127] Specifically, the locking member 420 is connected to the rotating rod by welding, riveting or bolting, and the locking member 420 is set with a convex plate structure. The protruding part of the locking member 420 can be embedded in the groove of the horizontal slide rail member 220, thereby fixing the horizontal slide rail member 230, and thus fixing the position of the bracket member 110 inside the special gas cabinet.

[0128] In some embodiments, the locking member 420 includes, but is not limited to, a convex plate.

[0129] The usage method of this embodiment is as follows:

[0130] When it is necessary to pull the bracket 110 out of the special gas cabinet, the operator rotates the locking part 420 to disengage the locking part 420 from the horizontal slide rail 220.

[0131] After the gas cylinder on the bracket 110 is replaced, the staff pushes the bracket 110 into the interior of the special gas cabinet and fixes the bracket 110 by rotating the locking part 420 so that the locking part 420 is embedded in the groove of the horizontal slide rail 220.

[0132] The advantage of this embodiment is that by setting a locking component inside the special gas cabinet, the position of the bracket inside the special gas cabinet can be fixed, thereby preventing the gas cylinder from shaking inside the special gas cabinet.
