Description

Technical Field

[0001] The utility model relates to the technical field of electric hook boxes, in particular to an electric hook box device for subways. Background Art

[0002] Since vehicles (urban rail vehicles) need to be uncoupled after running for a period of time, subway project jumpers are mostly installed at the car-end line card brackets at the two ends. When uncoupling, all connectors and car-end line card brackets on the active end need to be removed together (at least two people are required to complete) and fixed to the other connected car end. However, the subway requires that one person can complete the uncoupling, and jumper cables are not allowed to be used. In the past, the only car-end cable jumper method for projects that met the contract requirements was the electric hook head solution, but this solution was expensive. In order to meet the production cycle requirements and achieve the purpose of reducing costs, according to the characteristics of the vehicle end, it is very necessary to design a method to complete the car-end cable jumper through the hook electric hook box. The electric hook box solution is to install the high-voltage current connectors and low-voltage connectors on both sides on two separate boxes respectively.

[0003] In order to ensure the structural strength, the electric hook box currently produced is assembled into a box body with multiple thicker metal plates, but it is heavy as a whole, which increases the difficulty of operation in actual use. At the same time, the outer side is sealed, and the heat dissipation effect of the electric hook box is poor. In addition, the current electric hook box is sealed with sealant, and the sealing effect of the sealant will be reduced due to aging after long-term use, which will affect the internal components of the electric hook box.

[0004] Therefore, it is particularly important to design a subway electric hook box device to solve the above-mentioned defects. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] See also Figure 1-Figure 7 , the utility model provides a technical solution:

[0027] An electric hook box device for subways comprises an electric hook box body 1, a first cover plate 2 is installed at the left end of the top of the electric hook box body 1, a second cover plate 3 is installed at the right side of the electric hook box body 1, first lifting ears 4 are installed at the left and right sides and the bottom end of the back of the electric hook box body 1, a second lifting ear 5 is installed at the front of the electric hook box body 1, a plurality of groups of reinforcing ribs 6 and wire binding rods 7 are installed on the inner side wall of the electric hook box body 1, a terminal row mounting plate 8 is fixedly installed on the front of the interior of the electric hook box body 1, and a mounting frame 9 is installed at the right end of the interior of the electric hook box body 1.

[0028] Firstly, the electric hook box 1 is formed by laser welding of a first welding plate 101, a second welding plate 102, a third welding plate 103 and a fourth welding plate 104. The first welding plate 101, the second welding plate 102, the third welding plate 103 and the fourth welding plate 104 are all stainless steel plates. Compared with the original electric hook box, the electric hook box 1 formed by laser welding of multiple stainless steel plates not only reduces the thickness of the plate, so that the electric hook box 1 itself is lightweight, but also adds reinforcing ribs 6 to avoid deformation of the plate, thereby optimizing the structure. Furthermore, laser welding is used to seal the plates, so that the structure is more reliable and the sealing performance is better.

[0029] Furthermore, multiple groups of heat dissipation holes 105 are opened on the outer sides of the first welding plate 101, the second welding plate 102, the third welding plate 103 and the fourth welding plate 104. Small heat dissipation holes 105 are opened on the outer sides of multiple plates, which can improve the heat dissipation effect of the electric hook box 1 while preventing external debris from entering the inner side of the electric hook box 1.

[0030] Then, the first cover plate 2 and the second cover plate 3 are both aluminum alloy cover plates, and the edges around the inner sides of the first cover plate 2 and the second cover plate 3 are fixedly connected to the electric hook box 1 through the door frame edge 201. The door frame edge 201, the first cover plate 2 and the second cover plate 3 are all provided with mounting holes. The first cover plate 2 and the second cover plate 3 are both aluminum alloy cover plates, which further reduces the weight of the electric hook box 1 and achieves lightweight. At the same time, the first cover plate 2 and the second cover plate 3 are installed through the door frame edge 201, which ensures the installation strength while the door frame edge 201 improves the sealing effect at the door gap.

[0031] Furthermore, the tops of the first cover plate 2 and the second cover plate 3 are fixedly connected with door handles 202, and two sets of anti-slip parts 301 are installed on the second cover plate 3 and the electric hook box body 1. The door handles 202 facilitate the disassembly and assembly of the first cover plate 2 and the second cover plate 3, and the anti-slip parts 301 on the second cover plate 3 and the electric hook box body 1 can be connected by steel wires to improve the fixing effect of the second cover plate 3.

[0032] Secondly, the reinforcing ribs 6 and the wire tying rods 7 are welded to the inner wall of the electric hook box 1. The wire tying rods 7 are designed in a U-shaped structure. Through multiple sets of reinforcing ribs 6, deformation of the plate is avoided and structural optimization is achieved. Multiple sets of wire tying rods 7 provide many wire tying positions.

[0033] Finally, the mounting frame 9 is welded together by a first mounting beam 901, a second mounting beam 902 and a third mounting beam 903. The two ends of the first mounting beam 901 are fixedly connected to the reinforcing rib 6 and the third mounting beam 903 respectively, the two ends of the second mounting beam 902 are fixedly connected to the first mounting beam 901 and the electric hook box 1 respectively, and the two ends of the third mounting beam 903 are fixedly connected to the electric hook box 1. The mounting frame 9, which is welded together by the first mounting beam 901, the second mounting beam 902 and the third mounting beam 903, provides an internal mounting position for the electric hook box 1 while improving the internal structural strength of the electric hook box 1.

[0034] In this embodiment, the implementation scenario is specifically as follows: the stainless steel electric hook box 1 formed by laser welding of the first welding plate 101, the second welding plate 102, the third welding plate 103 and the fourth welding plate 104 not only reduces the thickness of the plate, so that the electric hook box 1 itself is lightweight, but also adds reinforcing ribs 6 on the inner wall of the electric hook box 1 to avoid deformation of the plate, and optimizes the structure. Multiple groups of wire binding rods 7 provide many wire binding positions, and laser welding is used to seal between the plates to make the structure more reliable and the sealing performance better. Small heat dissipation holes 105 are opened on the outer sides of the multiple plates to improve the heat dissipation effect of the electric hook box 1 while preventing external debris from entering the inner side of the electric hook box 1. The first cover plate 2 and the second The cover plates 3 are all aluminum alloy cover plates, which further reduce the weight of the electric hook box 1 and achieve lightweight. At the same time, the first cover plate 2 and the second cover plate 3 are installed through the door frame edge 201. While ensuring the installation strength, the door frame edge 201 also improves the sealing effect at the door gap. The whole operation process is simple and convenient. Compared with the existing subway electric hook box device, the utility model reduces the thickness of the plate through design, so that the electric hook box device itself is lightweight, and then adds reinforcing ribs 6 to avoid deformation of the plate, thereby achieving structural optimization. At the same time, the heat dissipation holes 105 opened on the outside of the electric hook box device have better heat dissipation performance, and laser welding is used for sealing between the plates to make the structure more reliable and greatly improve the sealing performance.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
