Description

Technical Field

[0001] The utility model relates to a storage rack, in particular to a storage device for a subway train bogie. Background Art

[0002] As the number of urban subway vehicles increases, operators need to purchase spare parts for the trains to ensure that new parts can be quickly replaced when a major train failure occurs, thereby ensuring the operation of the subway trains.

[0003] The bogies are usually stored in storage racks. Due to the large size of the bogies, they are usually stored in a single layer. In order to improve space utilization, some other spare parts will be placed on the second layer.

[0004] However, as the number of subway train models increases, the number of spare parts required by operators increases. On the one hand, the number of bogies that need to be stored increases, and the original single-layer storage can no longer meet the requirements. On the other hand, the turnover speed increases. If other spare parts are placed on the upper layer of the bogie, the use of the bogie will remain unchanged.

[0005] In this regard, some technical personnel in this field adopt the method of storing the bogies in two layers. However, due to the large size of the bogies and their heavy weight relative to the storage racks, in order to improve stability when storing in multiple layers, a non-detachable storage rack design has to be adopted, which leads to high costs and reduced loading and unloading efficiency.

[0039] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0040] A subway train bogie storage device, such as Figure 4 As shown, it is assembled from a plurality of storage racks, such as Figure 1 and Figure 3 As shown, the storage rack includes:

[0041] The main frame 4 is planar;

[0042] There are four columns 2, which are distributed at the four corners of the main frame 4 and are vertically arranged with respect to the base surface of the main frame 4;

[0043] There are four wheel pair positioning structures 5, which are distributed on the upper surface of the main frame 4 and are used to position the four wheels of the train bogie respectively;

[0044] Among them, a positioning column 1 is provided on the top of the column 2, and a positioning hole having the same number as the column 2 is provided at the bottom of the main frame 4, and each positioning hole corresponds to each positioning column 1 one by one, and the projection area of the positioning column 1 on the horizontal plane is completely located in the projection area of the positioning hole on the horizontal plane;

[0045] Furthermore, a plurality of lifting rings 3 are provided on the main frame 4 .

[0046] By designing the main frame 4 and the wheelset positioning structure 5, the train bogie can be positioned and fixed, thereby improving stability during multi-layer storage. In addition, multi-layer stacking can be achieved by using the positioning column 1, thereby improving space utilization and loading and unloading efficiency.

[0047] Generally, in some embodiments, Figure 2 As shown, the wheelset positioning structure 5 includes two positioning units that are relatively arranged, and the positioning units include a first support plate 5-1, a second support plate 5-2, a bonding plate 5-3, a first side plate 5-4 and a second side plate. The first support plate 5-1, the second support plate 5-2 and the bonding plate 5-3 are connected in a ring shape end to end, and the bonding plate 5-3 is attached to the main frame 4 and parallel to the horizontal plane. The second support plate 5-2 is vertically arranged and perpendicular to the connecting direction of the two positioning units. The first support plate 5-1 is inclined and forms an angle with the vertical direction. The first side plate 5-4 and the second side plate are arranged close to both sides of the main frame 4, and one edge is connected to the bonding plate 5-3.

[0048] In almost all embodiments, the distance between the first support plates 5 - 1 of the two positioning units is smaller than the distance between the second support plates 5 - 2 .

[0049] In this way, by setting the first support plate 5-1, the second support plate 5-2, the bonding plate 5-3, the first side plate and the second side plate in combination, and coordinating the directions of each plate, the pressure of the train bogie can be released on the main frame, keeping the wheelset positioning structure 5 lightweight, thereby improving stability during multi-layer storage.

[0050] In this embodiment, the bonding plate 5-3 is rectangular, and its two wide sides are respectively connected to the first support plate 5-1 and the second support plate 5-2, and its two long sides are respectively connected to the first side plate 5-4 and the second side plate.

[0051] In some embodiments, the first side panel 5 - 4 and the second side panel are fixed to the main frame 4 by positioning pins, and a row of openings can be provided on the corresponding main frame 4 to match products with different wheelbases.

[0052] In this embodiment, the main frame 4 includes two first longitudinal beams and two transverse beams, and two first longitudinal beams are respectively provided at both ends of the two transverse beams. Among the four columns 2, two columns 2 are arranged on one of the first longitudinal beams, and the other two columns 2 are arranged on the other first longitudinal beam.

[0053] The two cross beams are arranged in parallel, and the distance between the two cross beams is smaller than the distance between the two upright posts 2 arranged on the same first longitudinal beam.

[0054] The lifting rings 3 are arranged at both ends of the first longitudinal beam, so that during lifting, the lifting device can be kept at a greater distance from the lower train bogie, thereby avoiding damage to the lower train bogie.

[0055] A first triangular reinforcement plate 6 is provided between the column 2 and the first longitudinal beam, and a second triangular reinforcement plate 7 is provided between the first longitudinal beam and the cross beam;

[0056] The projection line segments of the first triangular reinforcing plate 6 and the second triangular reinforcing plate 7 on the first longitudinal beam coincide with each other.

[0057] By designing the projection line segments of the first triangular reinforcing plate 6 and the second triangular reinforcing plate 7 on the first longitudinal beam to overlap, and adopting a method of exposing the first longitudinal beam, the stability of the second layer and above storage racks when stacked horizontally can be improved.

[0058] Generally, the distance between the two cross beams is 60% to 80% of the length of the first longitudinal beam.

[0059] Alternatively, in some embodiments, the main frame 4 further includes a second longitudinal beam, both ends of which are respectively connected to two cross beams and are arranged parallel to the first longitudinal beam.

[0060] The operation process of this application is as follows: the operator uses the lifting equipment to lift the bogie into the storage rack, and limits the position of the bogie through the wheelset positioning structure 5 so that it will not move. When stacking is required, the storage rack is lifted using the lifting equipment using the lifting ring 3, so that the positioning hole below the main frame 4 corresponds to the position of the positioning column 1. After falling, the positioning column 1 is inserted into the positioning hole below the main frame 4, so that the upper and lower storage racks are not easily displaced. Then use the lifting equipment to lift the train bogie into the upper storage rack, thereby completing the stacking of the bogie storage rack.
