Description

Technical Field

[0002] A nitrogen generator is a device that uses air as raw material and uses physical methods to separate oxygen and nitrogen to obtain nitrogen. Nitrogen generators used in industry can be divided into three types according to different classification methods, namely, cryogenic air separation, molecular sieve air separation (PSA) and membrane air separation.

[0003] At present, some nitrogen generators are usually equipped with casters at the bottom of the base to quickly transfer the working position of the nitrogen generator. In order to ensure that the nitrogen generator after the transfer is not affected by external forces and moved again, the casters at the bottom have a braking function, but the staff need to actively operate it. On the one hand, when facing a large nitrogen generator, the stability of the nitrogen generator cannot be guaranteed by supporting it for a long time only by casters. On the other hand, each transfer of the nitrogen generator requires the staff to brake each caster. The operation process is cumbersome and it is easy to miss the caster at a certain position and cause mistakes in the work, which will also affect the stability of the nitrogen generator and bring inconvenience to the normal operation of the nitrogen generator.

[0004] Therefore, it is necessary to provide an improved technical solution to address the above-mentioned deficiencies in the prior art. Utility Model Content

[0031] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0032] Embodiment 1, this embodiment aims to provide a nitrogen generator that is easy to transfer, and its main function is to ensure the stability of the nitrogen generator after the transfer position, to ensure its subsequent stable operation, and at the same time to achieve rapid braking of the nitrogen generator, the operation is simple and fast, there will be no work errors, and the use effect is good.

[0033] Reference Figure 1 , Figure 2 and Figure 3 , including: a machine base 1 and a support leg, a nitrogen generator 2 is placed in the center of the upper surface of the machine base 1, casters 8 are installed at the four corners of the base bottom of the machine base 1, upper eaves 3 and lower eaves 4 are arranged on the sides around the machine base 1, and lifting transmission columns 5 are erected at the four corners of the machine base 1. The four lifting transmission columns 5 rotate synchronously and in the same direction, and the middle part of the lifting transmission column 5 is located between the upper eaves 3 and the lower eaves 4. Specifically, the upper and lower ends of the lifting transmission column 5 pass through the upper eaves 3 and the lower eaves 4 respectively, and the upper and lower ends of the lifting transmission column 5 are both equipped with tapered bearings 9, which are correspondingly nested in the bottom surface of the upper eaves 3 or the lower eaves 4, and the narrow side of the tapered bearing 9 faces upward and the wide side faces downward, and its purpose is to stably support the axial force generated by the lifting transmission column 5 The upper and lower eaves 3 and 4 are both fixed with anti-fall plates 10 by bolts on their bottom surfaces, and the anti-fall plates 10 prevent the tapered bearing 9 from falling from the bottom embedded holes of the upper and lower eaves 3 or 4. The top of the partial lifting transmission column 5 between the upper and lower eaves 3 and 4 is provided with a sprocket 11, and the sprockets 11 on the four lifting transmission columns 5 are linked by a chain 12, that is, the four sprockets 11 are surrounded by the chain 12, and the four sprockets 11 are meshed with the chain 12 at the same time, so that when one of the sprockets 11 rotates, the other three sprockets 11 will also rotate synchronously, and a motor 13 is fixed on the upper surface of one corner of the upper eaves 3 of the machine base 1, so as to drive the lifting transmission column 5 below to rotate by the motor 13.

[0034] Reference Figure 1 , Figure 2 and Figure 3 There are four supporting legs, which are distributed at the four corners of the machine base 1. Specifically, the supporting legs include: an angle plate 6 and a lifting plate 7. The inner angle surface of the angle plate 6 is close to the side of one corner of the lower eaves 4. The lifting plate 7 is horizontally placed on the top of the angle plate 6. The outer surface of the lifting transmission column 5 below the sprocket 11 is processed with a threaded section, and the lifting plate 7 is threadedly mounted on the corresponding lifting transmission column 5. The lifting transmission column 5 is rotated to drive the lifting plate 7 to move up and down along the threaded section. During this period, since the inner angle surface of the angle plate 6 is close to the outer side of the lower eaves 4, the angle plate 6 can limit itself and the lifting plate 7 to follow the rotation of the lifting transmission column 5, so that when the lifting transmission column 5 rotates, it can drive the lifting plate 7 to move up and down, and the angle plate 6 moves with the lifting plate 7.

[0035] In this embodiment, the height of the caster 8 is smaller than the height of the angle plate 6. The purpose is that when the angle plate 6 is lowered to the limit, that is, when the angle plate 6 is close to the upper surface of the lower eaves 4, the angle plate 6 is in contact with the ground, and the caster 8 is in a suspended state, thereby ensuring the stability of the placement of the nitrogen generator 2.

[0036] In actual use, the staff first uses the casters 8 of the machine base 1 to move the nitrogen generator 2 to the designated location. After arriving at the destination, the motor 13 is started, and one of the lifting transmission columns 5 is driven to rotate by the motor 13. The sprocket 11 on the lifting transmission column 5 cooperates with the chain 12 to simultaneously drive the other three sprockets 11. At that time, the four sprockets 11 rotate synchronously in the same direction, and the four lifting plates 7 also move downward synchronously. The four angle plates 6 follow the corresponding lifting plates 7 to move downward until the lifting plates 7 contact the upper surface of the lower eaves 4 of the machine base 1. At this time, the bottom of the angle plate 6 has contacted the ground, and the casters 8 are in a suspended state.

[0037] The nitrogen generator 2 in this embodiment has strong stability. At the same time, the nitrogen generator 2 in this example can achieve rapid braking when it moves to a designated location. The operation is simple and fast, and there will be no working errors, which further ensures the stability of the nitrogen generator 2 and ensures the stable operation of the nitrogen generator 2.

[0038] Embodiment 2 is basically the same as embodiment 1, except that the stability of the transmission of the chain 12 is ensured. Figure 1 and Figure 4 A tensioning member 14 is rotatably provided between the upper eaves 3 and the lower eaves 4. The tensioning member 14 is actually a tubular object. The tensioning member 14 is close to the outer side of the chain 12. The tensioning member 14 is rotatably mounted on the outside of the positioning rod 15, so that there is rolling friction between the tensioning member 14 and the chain 12 to reduce the resistance of the chain 12 during movement. A rotating cap is provided on the top of the positioning rod 15, and the rotating cap is thicker than the positioning rod 15. An external thread is provided on the bottom of the positioning rod 15. A through hole 16 is provided on the surface of the upper eaves 3, and a threaded hole 17 corresponding to the through hole 16 is provided on the surface of the lower eaves 4. The lower end of the positioning rod 15 passes through the through hole 16 and is rotatably inserted into the threaded hole 17. Among them, there are three through holes 16 and threaded holes 17 along the left and right directions of the machine base 1, so as to exchange the position of the tensioning member 14 and improve the tensioning effect of the chain 12.

[0039] It should be understood that the above description is merely exemplary and the embodiments of the present application do not limit this.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
