Description

Technical Field

[0001] The utility model relates to the technical field of steel cord production, in particular to a turnover transport frame for I-spool idlers. Background Art

[0002] The steel cord industry requires the use of I-spools for both winding and unwinding. When the I-spools are transferred and transported within or outside the factory, pallets are usually used to stack the I-spools layer by layer and then tie them up and fix them on the outside. Since there is no protective structure on the outside of the I-spools, this storage and transportation method has the probability of causing the exposed I-spools to be damaged by impact, such as deformation or paint damage. Surface damage will cause rust, and rust will make them unusable, so this method results in a waste of cost.

[0003] In the prior art, the turnover basket for monofilament spools with publication number CN116573277A previously proposed by the applicant can ensure that the spools do not collide with each other and the transportation is stable, but the loading process is complicated and it cannot accommodate more spools.

[0028] In order to better understand the technical content of the present invention, specific embodiments are given and described below with reference to the accompanying drawings.

[0029] Combine Figure 1 As shown, the present invention proposes a turnover transport frame for I-spool idlers, comprising a frame body. The frame body is constructed as a rectangular frame with an open top, including a bottom surface and four side surfaces, at least one of which is provided with a frame door 5.

[0030] In this way, the upper end of the frame is open. In addition, the frame door 5 is provided on the side to facilitate the user to stack the I-shaped wheels in the frame in sequence according to a predetermined rule.

[0031] The bottom of the frame door 5 is higher than the bottom surface of the frame body, so when stacking from bottom to top, the I-shaped wheels can easily form a stable stack at the bottom.

[0032] Furthermore, in order to ensure a stable placement of the spool in the frame, the shaft diameter of the spool is defined as D1 and the wheel surface length is defined as L, where the shaft diameter refers to the outer diameter of the shaft at the center of the spool disc, and the wheel surface length refers to the length from the root of the wheel surface to the edge along the diameter direction.

[0033] Combine Figure 5 、 Figure 6 , Figure 7 and Figure 8 As shown, the length A of the frame is set to be equal to or slightly greater than D1 + 2L + n(D1 + L), and the width B of the frame is set to be equal to or slightly greater than D1 + 2L + m(D1 + L), where m and n are positive integers.

[0034] In this way, when stacking empty spools, the latter one is stacked on the wheel surface of the previous one, and the rim is closely attached to the shaft of the previous one. This stacking method can save space to the greatest extent. That is, in the same space, the stacking quantity is large, but it is required that the overall size of the frame cannot be too large, otherwise the stacked spools are likely to loosen and become messy.

[0035] Therefore, when the length A of the frame is equal to D1 + 2L + n(D1 + L) and the width B of the frame is equal to D1 + 2L + m(D1 + L), the spools can be neatly stacked in the frame and each spool does not shake with each other.

[0036] Due to the strict matching of the above-mentioned dimensions of the frame and the spool, there is little space left for the user during stacking. Therefore, the size of the frame can be allowed to be slightly larger than the predetermined size. For example, the length of the frame can be designed as D1 + 2L + nD1 + L < A < D1 + 2.5L + n(D1 + L), and the width of the frame can be designed as D1 + 2L + m(D1 + L) < B < D1 + 2.5L + n(D1 + L). In this way, it is beneficial for the user to stack into the frame.

[0037] In an optional embodiment, m ∈ [4, 10], n ∈ [4, 10]. That is, when m and n are equal to 4, when the length direction of the frame can accommodate five spools, the width direction can also accommodate five spools. 25 spools can be placed in one layer, and 100 spools can be accommodated in four layers.

[0038] Furthermore, the bottom surface 101 and the side surface 102 of the frame are both composed of support columns and a mesh structure arranged between the support columns. The mesh structure is lighter in weight and more elastic than the plate structure, and is not easy to damage the spools.

[0039] Optionally, the mesh structure is formed by welding steel wires that cross each other.

[0040] Combined with Figure 1 and Figure 2 As shown, the frame includes four vertical rods 1, four bottom cross bars 2, three upper cross bars 3 and a plurality of mesh bars It is formed by welding steel wires that cross each other.

[0041] In this way, the frame structure composed of rigid rods and mesh fences has the characteristics of structural stability and light weight.

[0042] Furthermore, a middle crossbar is provided on the side with the frame door 5 , and the middle crossbar is parallel to the bottom crossbar 2 , and the fence 4 is set in a rectangular outline formed by the middle crossbar, the bottom crossbar 2 and the vertical pole 1 .

[0043] The frame door 5 is hingedly connected to the middle crossbar, and a door lock structure 6 is provided on the outside of the vertical pole 1. The door lock structure 6 is used to fix the frame door 5 to the vertical pole 1, so that the frame body forms a rectangular frame with an opening only at the upper end.

[0044] In this way, when the I-wheel is put into the frame or taken out from the frame, when the I-wheel is fully loaded, the door lock structure 6 can be locked, and the I-wheel is in a stable state in the frame and will not collide with the surrounding structures during turnover transportation.

[0045] Combine Figure 3 and Figure 4 As shown, the door lock structure 6 includes a socket 61, a latch 62 and a spring 63. The latch 62 is slidably connected to the socket 61. A socket seat 51 is provided on the outside of the frame door 5. When the frame door 5 is flipped upward to fit with the vertical rod 1, the latch 62 can move toward the frame door 5 and be inserted into the socket seat 51. The spring 63 is configured to make the latch 62 tend to move toward the frame door 5.

[0046] In this way, the latch 62 is extended toward the frame door 5 under normal conditions. Only when the door lock structure 6 needs to be closed, the latch 62 is manually pulled outward so that the head of the latch 62 is retracted into the socket 61. When the hole on the socket 51 of the frame door 5 corresponds to the position of the latch 62, the latch is released. The latch 62 is inserted into the socket 51 under the action of the elastic force of the spring 63, so that the frame door 5 is locked.

[0047] Furthermore, a base 11 is provided at the bottom of the upright 1, and the base 11 allows the bottom surface 101 to have a certain distance from the ground for a forklift to insert. A raised portion 12 is provided at the top of the upright 1 that is higher than the upper cross bar 3. When the frames are stacked, the raised portion 12 of the upright 1 can be inserted into the base 11.

[0048] Combine Figure 9 As shown, the turnover transport frames can be stacked to reduce the floor space, thereby greatly improving the turnover and storage efficiency of the spools.

[0049] In combination with the above embodiments, the turnover transport frame designed by the present invention is composed of rigid rods and mesh fences, with an opening on the top and a frame door on the side. The size of the frame is designed to just accommodate multiple rows of I-shaped wheels with wheel surfaces stacked on each other. Under the same size, when the existing I-shaped wheels are placed on the pallet in a 3*3 arrangement, the transport frame provided by the present application can be placed in a 5*5 arrangement, which is more than twice the capacity of the pallet. At the same time, this transport frame can ensure the stability of transportation, avoid the I-shaped wheels from hitting the external structure and causing deformation and damage, and greatly reduce storage and transportation costs.

[0050] While the present invention has been described above with reference to preferred embodiments, this is not intended to limit the present invention. Persons skilled in the art will readily appreciate that various modifications and variations may be made without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims.
