[0002] Train braking is to artificially stop the movement of the train, including slowing it down, not accelerating it or stopping it. Releasing or weakening the braking effect of a braked train or locomotive is called relief.

[0027] Embodiment 1, in combination with the attached Figure 1 A railway locomotive brake system maintenance device comprises a main frame 1, a mounting shaft 2 is arranged on the top of the main frame 1, and a mounting sleeve 3 is sleeved on the shaft body of the mounting shaft 2 near the end thereof, a plurality of radial extension plates 4 are uniformly spaced along the circumference of the mounting sleeve 3, and a tool box 5 for containing maintenance tools is rotatably connected between the outer ends of two corresponding radial extension plates 4;

[0028] As required, the main frame 1 includes a bottom frame 11 , and vertical frames 12 are provided at both ends of the top surface of the bottom frame 11 , and the mounting shaft 2 is provided between the tops of the two vertical frames 12 .

[0029] Furthermore, the stand 12 includes a first diagonal support rod 121 and a second diagonal support rod 122 in an inverted V shape, and the lower ends of the first diagonal support rod 121 and the second diagonal support rod 122 are respectively connected to the two sides of the top surface of the base frame 11.

[0030] As required, the bottom surface of the main frame 1 is provided with running wheels 13 .

[0031] Among them, there is a damped rotation connection between the mounting shaft 2 and the main frame 1 and / or between the mounting shaft 2 and the mounting sleeve 3; specifically, the damping effect of the damped rotation connection can overcome the weight of the toolbox 5; that is, after the radial extension plate 4 carrying the toolbox 5 is actively rotated to any position by humans, after the staff lets go, the toolbox 5 can stay at this position and will not drop due to the weight of the toolbox 5.

[0032] As needed, the damping rotational connection can achieve the damping effect by setting a damping sleeve at the rotational connection, and a braking structure can also be set, such as a brake, a gear assembly, a locking screw, etc. to achieve the damping effect; the specific damping structure is not limited here.

[0033] When in use, the staff can adjust and rotate the radial extension plate 4 according to their own needs to make the required tool box 5 in a suitable position, and then they can easily take out the maintenance tools in the tool box 5; and the setting of multiple tool boxes 5 can realize the function of classifying and placing different types of maintenance tools.

[0034] According to the needs, the number of tool boxes 5 can be three or four.

[0035] In this embodiment, there are three tool boxes 5. For example, one of the tool boxes 5 contains tools for repairing the circuit of the railway locomotive braking system, such as all tools such as a multimeter and an electric pen; one of the tool boxes 5 contains tools for repairing the air circuit of the railway locomotive braking system; and one of the tool boxes 5 contains tools for repairing the mechanical parts of the railway locomotive braking system.

[0036] Embodiment 2, combined with the attached Figure 1-3 , a railway locomotive brake system maintenance device, based on the first embodiment, the tool box 5 includes a box body 51 with a right-angle trapezoidal cross section, and a box cover 52 is hingedly connected to the bottom of the hypotenuse side of the box body 51, and the box cover 52 has a storage cavity;

[0037] A limiting member 53 for limiting the opening angle of the box cover 52 is provided on the bottom surface of the box body 51 .

[0038] Preferably, in the open position, the angle between the inner cover surface of the box cover 52 and the horizontal is 0-30 degrees, and the outer side edge of the inner cover surface of the box cover 52 is lower than the inner side edge of the inner cover surface of the box cover 52.

[0039] Specifically, the top of the box cover 52 and the top of the box body 51 are locked, so that the box cover 52 can be stably in a closed state.

[0040] Specifically, in the open position, the inner side edge of the inner cover surface of the box cover 52 faces the side of the staff's working area.

[0041] This arrangement allows the parts disassembled during the maintenance process using the tools in the toolbox 5 to be placed in the storage cavity of the cover 52 of the toolbox 5, which not only prevents the disassembled parts from being misplaced or lost, but also ensures that the parts and the maintenance tools used for disassembling and assembling the parts are located in the same toolbox 5, and can realize the function of classifying and placing the disassembled parts in correspondence with the maintenance tools used for disassembling and assembling the parts, thereby improving the maintenance efficiency.

[0042] Embodiment 3, in combination with the attached Figure 2-4 , a railway locomotive brake system maintenance device, based on the first or second embodiment, the first diagonal brace rod 121 and the second diagonal brace rod 122 are telescopic rods, the bottoms of the fixed parts of the first diagonal brace rod 121 and the second diagonal brace rod 122 are hinged to the base frame 11, and the tops of the telescopic parts of the first diagonal brace rod 121 and the second diagonal brace rod 122 are connected to the mounting shaft 2 in a damping rotation manner;

[0043] The stand 12 also includes a bidirectional screw rod 123 rotatably connected to both ends of the base frame 11 , both threaded portions of the bidirectional screw rod 123 are provided with a threaded slider 124 , and a driving rod 125 is hinged between the threaded slider 124 and the corresponding diagonal support rod telescopic portion.

[0044] In this way, by rotating the bidirectional screw rod 123, the bidirectional screw rod 123 can drive the corresponding two threaded sliders 124 to move relative to or away from each other. At this time, the inclination angle of the driving rod 125 changes under the action of the threaded slider 124, thereby driving the telescopic portion of the first diagonal support rod 121 and the telescopic portion of the second diagonal support rod 122 to telescope or extend at the same time. At this time, the mounting shaft 2 descends or rises, causing the tool box 5 to descend or rise, thereby enabling the tool box 5 to descend or rise at the position closest to the staff in the horizontal plane, thereby achieving the optimal height for the staff to conveniently take the maintenance tools in the tool box 5.

[0045] As required, the two bidirectional screw rods 123 are coupled with each other through transmission, for example, through a belt set, a chain set, etc.

[0046] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
