Description

Technical Field

[0001] This utility model relates to the field of liquid nitrogen tank technology, specifically to a protective structure for a liquid nitrogen tank mobile frame. Background Technology

[0002] In fields such as medical treatment, scientific research, and industrial production, liquid nitrogen tanks often need to be moved between different sites using mobile frames. However, existing liquid nitrogen tank mobile frames generally lack effective protective measures, making the tanks very susceptible to damage from impacts during movement.

[0003] Firstly, during movement, the mobile frame experiences vibrations and bumps due to uneven ground, crossing thresholds, or sudden braking. Traditional mobile frames mostly only have simple load-bearing functions and lack dedicated protective structures to buffer these external impacts, causing the liquid nitrogen tank to directly bear the vibrations and resulting in frequent hard collisions between the tank and the mobile frame. Secondly, different tank specifications, i.e., differences in tank diameter, lead to poor compatibility between the fixed load-bearing space of the mobile frame and the liquid nitrogen tank, easily resulting in gaps that cause violent shaking and damage during movement, posing safety hazards. Therefore, considering improving the protective function of the tank during transportation to enhance its adaptability and facilitate the movement and transportation of tanks of different specifications, we propose a protective structure for a liquid nitrogen tank mobile frame.

The two clamping plates are used to clamp the liquid nitrogen tank body.

[0008] A vertical stop block, installed on the horizontal bracket, is used to limit the position of the liquid nitrogen tank body.

[0009] Preferably, a counterweight compartment is installed below the horizontal bracket, and the counterweight compartment is used to hold filler to lower the overall center of gravity.

[0010] Preferably, the clamping plate has an arc-shaped groove in the middle for fitting against the outer wall of the liquid nitrogen tank.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Please see Figures 1-4 The present invention will describe the above technical solution in detail through the following embodiments:

[0027] The protective structure of the liquid nitrogen tank moving frame in this embodiment can keep the tank fixed during the movement of the liquid nitrogen tank and reduce collisions. It includes a horizontal bracket 1 with moving wheels 3 and a clamping and protective part in order to be suitable for transporting tanks of different sizes.

[0028] like Figure 3 and Figure 4 The structure shown includes a clamping and protective part comprising vertically mounted vertical positioning frames 2 around the horizontal bracket 1. The four vertical positioning frames 2 are centrally symmetrically arranged in a square configuration. Two vertical positioning frames 2 form a group, and a screw 7 is inserted between them. In order to maintain the positioning of the screw 7, nuts 8 are threadedly installed at both ends of the screw 7 for fixation.

[0029] To accommodate liquid nitrogen tanks of different diameters, clamping plates 6 are slidably mounted on the screws 7 on both sides, wherein the clamping plates are provided with... Figure 3 The arc-shaped groove shown forms a circular clamping cavity between the two clamping plates 6 to hold the liquid nitrogen tank body 9. The nut 8 threaded on the screw 7 can squeeze the two clamping plates 6 to adjust the relative clamping distance, thus making it suitable for tanks of different specifications. It has strong adjustability and a wide range of applications.

[0030] Considering that the tank body has limited fixing effect at the opening between the two side clamps 6, which can easily damage the curvature of the arc groove, and that the inner wall of the clamp 6 is provided with a rubber pad layer, which can easily cause the tank body to shake in the direction of the two side screws 7, this embodiment has a vertical stop block 5 detachably installed on the horizontal bracket 1 and on the side corresponding to the screw 7. The vertical stop block 5 works with the clamp 6 to complete the fixing.

[0031] Considering that the liquid nitrogen tank has a high center of gravity during movement and is prone to tipping over, this embodiment has a counterweight compartment 4 installed below the horizontal bracket 1. The counterweight compartment 4 can be filled with sand, gravel, or other fillers to lower the overall center of gravity, thereby improving the stability of the frame during movement.

[0032] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
