Description

Technical Field

[0001] The utility model belongs to the technical field of industrial gas cylinder production, and particularly relates to a gas cylinder assembly jig. Background Art

[0002] A modular nitrogen generator is a molecular sieve-based nitrogen generator. Its principle is to utilize the adsorption properties of high-quality molecular sieves to remove oxygen and impurities from the air, thereby generating high-purity nitrogen. To improve nitrogen production efficiency, modular nitrogen generators are generally equipped with multiple adsorption cylinders. Compressed air passes through the cylinders from bottom to top, where oxygen, carbon dioxide, and moisture are adsorbed, and nitrogen flows out from the top. Switching between multiple adsorption cylinders ensures stable nitrogen production and provides conditions for regeneration after a single adsorption cylinder becomes saturated.

[0003] When assembling a modular nitrogen generator, multiple adsorption cylinders are typically mounted on the same base. Compressed air can enter each adsorption cylinder through a cavity within the base. However, sealing the connection between the adsorption cylinder and the base presents certain difficulties. Since the adsorption cylinder is a slender cylindrical structure, connecting the bottom of the adsorption cylinder to the base in a vertical position requires operation at the bottom of the base. If the slender cylinder is unstable and tilts, it is easy for it to collide with each other and be damaged, endangering the safety of the operators. Therefore, the existing assembly method is to hoist the adsorption cylinder, and two or more operators cooperate to manually lift the base to tighten the bolts. This assembly method is unsafe, inefficient, and cannot be performed by one person, so improvements are needed. Utility Model Content

[0004] In response to the above problems and technical needs, the utility model provides a gas cylinder assembly jig, which can be used to quickly install the base cavity and adsorption cylinder in a static state. The installation does not require the cooperation of multiple people, and one person can complete the operation, which is safer to operate and more efficient to assemble.

[0005] The technical solution of the present utility model is as follows: a gas cylinder assembly jig, including a split support frame, an air intake base and an adsorption cylinder, the air intake base is placed horizontally on the split support frame, the split support frame limits the air intake base, screw holes are provided on the air intake base, the adsorption cylinder is placed vertically on the upper surface of the air intake base, the split support seat supports the air intake base from both ends, the bottom of the air intake base is an assembly space, the adsorption cylinder and the air intake base are connected by screws, and the screws pass through the screw holes from bottom to top to lock the adsorption cylinder; the split support frame includes a first bracket and a second bracket, the first bracket and the second bracket are parallel and symmetrically arranged, and the top surfaces of the first bracket and the second bracket are symmetrically provided with multiple support positions, the air intake base can be embedded and fixed in two opposite support positions, and the assembly space provides space for the screws to assemble from the bottom to the top. In this solution, a split support frame is used to lift the air intake base to keep it stable and horizontal. The air intake base can support the adsorption cylinder on the top to keep the adsorption cylinder in a stable alignment state. The assembly space at the bottom provides space for manual operation. With the support of the split support frame, the air intake base and the adsorption cylinder can maintain a stable suspended alignment state. No auxiliary support is required.

The end support frames are symmetrically provided at both ends of the bottom plate, and the end support frames are arranged obliquely upward. A long support plate is provided on the top of the end support frames. The outer sides of the tops of the two end support frames are connected by an outer baffle. The outer baffle blocks the outer sides of the long support frames on both sides. There is a gap between the inner sides of the two long support frames. One or more short support frames are vertically provided on the inner sides of the outer baffles. The short support frames and the long support frames are located on the same horizontal plane. There are support clips between the long and short support frames, and between the short support frames and the short support frames. The air intake base can be embedded in the support clips. The short and long support frames on both sides form support clips, which can limit the position of the air intake base, so that the air intake base remains in a horizontal and stable state.

[0007] Furthermore, the long and short support plates are each provided with a plurality of assembly positioning holes, the diameter of which is larger than the diameter of the screw holes. When the air intake base is inserted into the support bracket, the assembly positioning holes correspond to the screw holes, and the screw holes can be tightened through the assembly positioning holes.

The bottom of the end arc plate is connected to the base plate and is spaced a certain distance from the end of the base plate. The top of the end arc plate is connected to the long support plate. The side arc plates are connected to the inside and outside of the end arc plate. The inside of the side arc plate is connected to the end arc plate. The bottom of the side arc plate is connected to the base plate, and the top is connected to the long support plate. The end support frame composed of the end arc plate and the side arc plate has high support strength while being lightweight. It is not easy to deform after long-term use.

[0009] Furthermore, both ends of the outer baffle are respectively connected to the top ends of the two outer side arc plates.

[0010] Furthermore, a reinforcement plate is provided on the bottom plate. The reinforcement plate is disposed within the space enclosed by the end guard plate and the two side arc plates, with both ends of the reinforcement plate connected to the inner sides of the two side arc plates.

[0011] Furthermore, the air inlet base includes a substrate and a cavity. The substrate is a straight plate. A rectangular cavity of the same length as the substrate is connected below the substrate. Both ends of the cavity are open. The width of the substrate is greater than the width of the cavity. A row of air inlet holes is provided in the middle of the substrate. The air inlet holes are connected to the cavity. Four screw holes are provided around each air inlet hole, and the screw holes are penetrated through the two side edges of the substrate.

[0012] Furthermore, the circumference of the adsorption cylinder is provided with four reinforcing ridges, the bottom of the reinforcing ridges is provided with mounting holes, the adsorption cylinder is installed corresponding to the air inlet hole, and the four mounting holes correspond one to one to the four screw holes.

[0013] The beneficial effects of the present invention are as follows: the present invention adopts a first bracket and a second bracket with two completely identical structures to support the air intake base. Since the first bracket and the second bracket are split brackets, the distance between them can be adjusted arbitrarily. Therefore, the present bracket can support air intake bases of various length specifications, which is flexible to use and highly practical. The two brackets are supported at both ends of the air intake base, raising the air intake base so that the operator can lock the air intake base from the bottom. The operation can be completed by a single person, which is convenient, safe, and greatly improves the operating efficiency.
