Description

Technical Field

[0001] This utility model relates to the field of liquid nitrogen tank transportation technology, specifically to a liquid nitrogen tank transportation device. Background Technology

[0002] Liquid nitrogen tanks are important equipment for storing and transporting liquid nitrogen and are widely used in many fields such as biomedicine, scientific research and industry. Because liquid nitrogen tanks are usually large in size and heavy in weight, they need to be lifted by hoisting equipment to be transported onto transport trolleys during handling, installation and maintenance.

[0003] The traditional method of directly hoisting liquid nitrogen tanks from the ground onto a transport trolley involves using ropes or slings to secure the tanks before hoisting them onto the trolley. This method not only easily causes wear and scratches to the outer shell of the liquid nitrogen tank, affecting its appearance and service life, but also the ropes or slings may slip or come loose during the hoisting process due to uneven force, causing the liquid nitrogen tank to fall and resulting in a serious safety accident.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a liquid nitrogen tank transportation device to solve the problems mentioned in the background art, such as the easy wear and scratches on the outer shell of the liquid nitrogen tank when it is hoisted onto the transport trolley by ropes or slings, and the possibility of uneven force on the ropes or slings during the hoisting process, which may cause them to slip or detach and lead to the liquid nitrogen tank falling.

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Please see Figure 1-5 This utility model provides a technical solution:

[0040] Liquid nitrogen tank transport equipment, including:

[0041] The transport unit 1 is located at the bottom of the liquid nitrogen tank body 100 and is used to transport the liquid nitrogen tank body 100.

[0042] The positioning unit 2 includes a lifting component 21 located at the upper end of the transport unit 1 and outside the liquid nitrogen tank body 100 for limiting and lifting the liquid nitrogen tank body 100, and a locking component 22 located on one side of the transport unit 1 for cooperating with the lifting component to limit the liquid nitrogen tank body 100.

[0043] It should be noted that when the liquid nitrogen tank body 100 placed on the ground needs to be hoisted onto the transport vehicle, the locking component 22 is opened and the lower end of the lifting component 21 is extended to contact the ground. The liquid nitrogen tank body 100 is pushed along the ground to the upper end of the lifting component 21. The lifting component 21 lifts the liquid nitrogen tank body 100 upward, so that the bottom of the lifting component 21 is separated from the ground. Then the locking component 22 is closed, so that the locking component 22 presses against the outside of the liquid nitrogen tank body 100, completing the loading and limiting work of the liquid nitrogen tank body 100. The entire process does not require the liquid nitrogen tank body 100 to be tied, avoiding wear and scratches on the liquid nitrogen tank body 100.

[0044] As an improvement, such as Figure 1-2 As shown, the transport unit 1 includes:

[0045] The support frame 11 is used to support the liquid nitrogen tank body 100;

[0046] Rollers 12 are installed at the lower end of the support frame 11 for transporting the support frame 11;

[0047] The pull rod 13 is fixedly connected to one side of the support frame 11 relative to the locking assembly 22, and is used to move and adjust the support frame 11.

[0048] Furthermore, such as Figure 3-4 As shown, the lifting component 21 includes:

[0049] Two sets of cylinders 211 are provided, which are respectively installed on the bottom sides of the support frame 11;

[0050] The lifting rod 212 is fixedly connected to the drive end of the cylinder 211, and the lifting rod 212 is in an inverted L shape;

[0051] The support plate 213 is located at the lower part of the support frame 11 and is used to support the lower end of the liquid nitrogen tank body 100.

[0052] The first baffle 214 is fixedly connected to the upper end of the support plate 213 near the edge. The first baffle 214 is arc-shaped and is used to limit the liquid nitrogen tank body 100.

[0053] Furthermore, one side of the support plate 213 is provided with an inclined opening 2131 for transitioning the liquid nitrogen tank body 100 from the ground to the upper end of the support plate 213.

[0054] Among them, the first baffle 214 is fixedly connected to a top rod 2141 on one side of the liquid nitrogen tank body 100, which is used to support the first baffle 214.

[0055] The top rod 2141 is fixedly connected to both ends of the guide rod 2241, and the inner side of the bearing frame 11 is provided with a guide rail 111 for guiding the up and down movement of the slider 2142.

[0056] As an improvement, such as Figure 4-5 As shown, the locking assembly 22 includes:

[0057] Card holder 221 is fixedly connected to one side of the support frame 11 opposite to the pull rod 13, and the pull rod 13 is L-shaped;

[0058] A support rod 222 is placed between the card holder 221 and the support frame 11, and a threaded hole 2221 is provided in the middle of the inside of the support rod 222.

[0059] A threaded rod 223 is threadedly connected inside the threaded hole 2221. One end of the threaded rod 223 is fixedly connected to a rotating rod 2231 for adjusting the rotation of the threaded rod 223. A limiting disc 2232 is fixedly connected to one end of the threaded rod 223 relative to the rotating rod 2231.

[0060] A top arc 224 is located at one end of the threaded rod 223 relative to the rotating rod 2231. A retainer 226 is fixedly connected to one side of the top arc 224. A limiting groove 2261 for accommodating the disk is provided inside the retainer 226 and outside the disk.

[0061] Furthermore, the top arc 224 is fixedly connected to a top rod 2141 on one side of the liquid nitrogen tank body 100 and on both sides of the sleeve 226;

[0062] One end of the top rod 2141 relative to the top arc 224 is fixedly connected to a limiting block 2242;

[0063] A guide sleeve 225 is fixedly connected to one side of the support rod 222. The guide sleeve 225 has a guide groove 2251 inside for accommodating and guiding the limiting block 2242.

[0064] It should be noted that: in the specific implementation process of this utility model, if... Figure 1-3 As shown, when it is necessary to hoist the liquid nitrogen tank body 100 placed on the ground into the support frame 11 for transportation, firstly, the support rod 222 is taken out from the card seat 221, and the control cylinder 211 is retracted downwards. The cylinder 211 drives the support plate 213 to move downwards until it contacts the ground through the lifting rod 212. At this time, the liquid nitrogen tank body 100 is pushed towards the support plate 213. The liquid nitrogen tank body 100 moves along the inclined opening 2131 to the top of the support plate 213 and the outer side of the liquid nitrogen tank body 100 contacts the first baffle 214. The control cylinder 211 pushes upwards, and the cylinder 211 drives the support plate 213 to move upwards through the lifting rod 212. The support plate 213 drives the liquid nitrogen tank body 100 at its upper end to move upwards, so that the lower end of the support plate 213 is separated from the ground, completing the work of transporting the liquid nitrogen tank body 100 onto the trolley. The transportation process does not require the use of ropes for hoisting, ensuring that the liquid nitrogen tank body 100 will not be worn or fall off.

[0065] like Figure 1-2 , Figure 4-5 As shown, the support rod 222 is then placed inside the mounting base 221. The rotating rod 2231 is rotated, which drives the threaded rod 223 to rotate within the threaded hole 2221. The threaded rod 223 drives the limiting disc 2232 to rotate within the sleeve 226. Under the action of the tangential force between the threaded rod 223 and the threaded hole 2221, the threaded rod 223 drives the top arc 224 to move through the sleeve 226. The top arc 224 drives the limiting block 2242 to move along the guide groove 2251 through the guide rod 2241, so that the liquid nitrogen tank body 100 is clamped by the top arc 224 and the first baffle 214, which prevents the liquid nitrogen tank body 100 from tipping over during transportation and reduces the risk of transporting the liquid nitrogen tank body 100.

[0066] like Figure 1 As shown, during the lifting and lowering process of the first baffle 214, the first baffle 214 drives the slider 2142 to lift and lower along the guide rail 111 via the push rod 2141, ensuring that the push rod 2141 always presses against the first baffle 214, thereby improving the reliability of the first baffle 214.
