Description

Technical Field

[0001] The utility model belongs to the technical field of superconducting cable laying, in particular to a superconducting cable bracket. Background Art

[0002] With the successive launch of superconducting cable demonstration projects, the installation sites of superconducting cables are closer to engineering application scenarios, making the superconducting cable laying paths more and more complicated, and requiring certain innovations based on the characteristics of superconducting cables. Among them, superconducting cable bending is the most common one. The difference from traditional cables is that: (1) superconducting cables work in a low-temperature environment (usually liquid nitrogen), and there is thermal expansion and contraction before and after cooling, that is, the superconducting cable will have a thermal expansion and contraction displacement of about 3‰ along the entire laying path; (2) the superconducting cable core will become brittle and hard in a low-temperature environment. The double-layer vacuum insulation pipe (hereinafter referred to as the Dewar tube) on the outer layer of the cable core itself has a certain rigidity and elasticity. Therefore, the bending radius of the superconducting cable cannot be too small, and it cannot be subjected to external bumps, otherwise the cable core and the Dewar tube may be damaged.

[0003] Conventional cable trench cable supports are generally angle steels, which may have protrusions and sharp corners on their surfaces, posing a risk of scratches when the superconducting cable is extended or moved. Utility Model Content

[0004] Based on the above problems, the purpose of the present invention is to provide a superconducting cable support that can protect the superconducting cable from damage.

[0005] In order to overcome the deficiencies of the prior art, the technical solution provided by the present invention is:

[0006] A superconducting cable support, comprising:

[0007] base;

[0008] A transverse roller mechanism includes two transverse roller supports arranged on opposite sides of the base and a transverse roller assembly rotatably arranged between the two transverse roller supports, wherein the transverse roller assembly includes at least two transverse rollers whose axes are arranged parallel to each other.

[0009] The vertical roller mechanism comprises two vertical roller assemblies arranged at both ends of the axial direction of the transverse roller assembly, and the vertical roller assembly comprises two vertical rollers rotatably arranged on both sides of the radial direction of the transverse roller.

[0010] In one embodiment, the base includes two symmetrically arranged support plates, and the transverse roller bracket is vertically fixed on the corresponding support plates.

[0012] In one embodiment, at least two connecting plates are connected between the two support plates.

[0013] In one embodiment, a vertical roller bracket is fixed to the upper end of the transverse roller bracket, and the upper end of the vertical roller is rotatably arranged on the vertical roller bracket and the lower end is rotatably arranged on the connecting plate.

[0014] In one embodiment, the transverse roller is dumbbell-shaped.

[0015] In one embodiment, the outer surface of the transverse roller is a curved surface.

[0016] In one embodiment, support shafts are provided at both ends of the transverse roller, and the support shafts are supported on the transverse roller bracket via first bearings.

[0017] In one embodiment, the vertical roller is cylindrical.

[0018] In one embodiment, a rotating shaft is passed through the vertical roller, and the rotating shaft is supported on the vertical roller bracket and the connecting plate via a second bearing.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] 1. The linear movement of the superconducting cable is guided by the transverse roller mechanism, and the turning movement of the superconducting cable is guided by the vertical roller mechanism, which can provide all-round protection for the superconducting cable during laying to avoid damage;

[0021] 2. The transverse roller mechanism includes at least two transverse rollers arranged in parallel above and below.

[0022] 3. The vertical roller mechanism includes four vertical rollers in the front, back, left and right directions, which can limit the superconducting cable in four directions. On the one hand, it ensures that the cable can move smoothly on the cross rollers, and on the other hand, it ensures that the cable is not damaged by sharp corners and rigid materials.

[0033] The above scheme is further described below with reference to specific examples. It should be understood that these examples are intended to illustrate the present invention and are not intended to limit the scope of the present invention. The implementation conditions used in the examples can be further adjusted according to the conditions of the specific manufacturer. The implementation conditions not specified are generally those used in routine experiments.

[0034] See also Figure 1 , is a superconducting cable support of the utility model, comprising a base, a transverse roller mechanism and a vertical roller mechanism.

[0035] The base includes two symmetrically arranged support plates 1. Preferably, the support plates 1 are L-shaped. The base can be a profile or a component made of non-magnetic steel or non-metallic material.

[0036] In order to improve the stability of the base structure, two connecting plates 4 are connected between the two support plates 1. It should be understood that in other embodiments, a greater number of connecting plates 4 can be connected between the two support plates 1, and the present invention does not impose any limitation thereto.

[0037] The transverse roller mechanism includes two transverse roller brackets 2 arranged on opposite sides of the base, and a transverse roller assembly rotatably arranged between the two transverse roller brackets 2. The transverse roller brackets 2 are plate-shaped members and are vertically fixed to the support plate 1. The transverse roller assembly includes two transverse rollers 3 arranged with their axes parallel to each other. The transverse roller brackets 2 can be profiles or components made of non-magnetic steel or non-metallic materials.

[0038] During superconducting cable laying, the superconducting cable is placed between two transverse rollers 3. The lower transverse roller 3 supports the main body of the superconducting cable, while the upper transverse roller 3 prevents the cable from bowing due to local bulging during extension, thus ensuring a smooth transition to the upper limit. It should be understood that in other embodiments, a greater number of transverse rollers may be provided as needed to accommodate the laying of superconducting cables of varying heights, and this is not a limitation of the present invention.

[0039] like Figure 2As shown, the cross roller 3 is in the shape of a dumbbell with a thin middle and thick ends, so as to limit the transportation of the superconducting cable. The outer surface of the cross roller 3 is an arc surface, which can avoid damage to the superconducting cable. The material of the cross roller 3 is a non-metallic material with a certain compression elasticity, which can increase the contact area with the cable and reduce the force on the cable.

[0040] In order to facilitate the rotational connection between the transverse roller 3 and the transverse roller bracket 2, support shafts 3-1 are provided at both ends of the transverse roller 3, and the support shafts 3-1 are supported on the transverse roller bracket 2 via first bearings.

[0041] The vertical roller mechanism includes two vertical roller assemblies arranged at the axial ends of the transverse roller assembly. Each vertical roller assembly includes two vertical rollers 5 rotatably arranged on both sides of the radial direction of the transverse roller 3. Specifically, the vertical rollers 5 are rotatably arranged on the front and rear sides of the transverse roller bracket 2 in the moving direction of the superconducting cable.

[0042] In order to facilitate the installation of the vertical roller 5, a vertical roller bracket 6 is fixed to the upper end of the transverse roller bracket 2. The vertical roller bracket 6 can be a profile or a component, and the material is non-magnetic steel or non-metallic material.

[0043] The vertical roller 5 is cylindrical, with a rotating shaft passing through it. The two ends of the rotating shaft are supported on the vertical roller bracket 6 and the connecting plate 4 respectively through the second bearing. The vertical roller 5 is made of non-metallic material with a certain degree of compression elasticity, which increases the contact area with the cable and reduces the stress on the cable.

[0044] The working principle of this utility model is:

[0045] When laying the cable, the superconducting cable is placed between the two transverse rollers 3. The transverse roller 3 at the bottom supports the main body of the superconducting cable, and the transverse roller 3 at the top can play the role of smooth transition of the upper limit. When the superconducting cable turns, the vertical roller assemblies on both sides can guide and protect the superconducting cable in four directions of front, back, left and right to ensure smooth cable laying.

[0046] In summary, the cable support can ensure the smooth laying of superconducting cables, improve work efficiency, and reduce cable damage.

[0047] The above examples are intended only to illustrate the technical concepts and features of this utility model. Their purpose is to enable those familiar with the art to understand the content of this utility model and implement it accordingly. They are not intended to limit the scope of protection of this utility model. Any equivalent changes or modifications based on the spirit of this utility model shall be included in the scope of protection of this utility model.
