Description

Technical Field

[0001] The utility model relates to the technical field of locomotive maintenance auxiliary tools, in particular to a locomotive vehicle coupler auxiliary maintenance device. Background Art

[0002] The coupler is the hook at both ends of the locomotive, used to connect the locomotive and the vehicle or between vehicles, and has functions such as connection, traction, and buffering, which can keep a certain safety distance between vehicles. It is one of the essential components on the locomotive and the vehicle. Since the coupler is subjected to large forces during the operation of the locomotive or vehicle and is an important component to ensure safe driving, it needs to be overhauled and maintained irregularly. In order to adapt to the slight differences in angles and heights caused by track directions, terrain, etc. between the two connected car bodies during operation, the coupler is generally installed in a movable manner and is installed and connected through special coupler seats, coupler beams, etc. When performing overhaul and maintenance, usually the locomotive or vehicle needs to be towed into the overhaul workshop first, and then multiple people cooperate to lift the coupler at a certain angle to check whether the related components such as its connection and support are normal. The coupler has a large overall weight and requires multiple people to cooperate to lift it. Moreover, when overhauling, the vehicle needs to be transferred from the track to the workshop. Therefore, the overhaul process is complex, the efficiency is low, and the human resources consumption is large. Content of the Utility Model

A pushing handle and a hand rod sleeve are also fixedly installed on the maintenance support plate, and an operating hand rod for sleeving and cooperating with the handle sleeve of the jack is partially inserted into the hand rod sleeve.

[0005] As a preferred technical solution, the pushing handle is obliquely arranged on the maintenance support plate, and the hand rod sleeve is fixed on the outer wall of the pushing handle.

[0006] As a preferred technical solution, the maintenance support platform includes two support columns arranged oppositely, a support circular plate is fixedly installed at the top ends of the two support columns, and the jack is fixed on the support circular plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments. In the following detailed description, only some exemplary embodiments of the present utility model are described by way of illustration. It is understood that those of ordinary skill in the art can recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present utility model. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of protection of the claims.

[0017] As Figures 1 to 4 shown, the locomotive and rolling stock coupler auxiliary maintenance device is used to lift the coupler 1 by a certain angle during the overhaul and maintenance of the coupler 1, so as to form a certain gap between the coupler 1 and the coupler seat and the coupler beam, facilitating the inspection and replacement operation of components. The support for the coupler 1 is stable, which helps to improve the operation speed and operation safety. The locomotive and rolling stock coupler auxiliary maintenance device specifically includes a maintenance support plate 2, on which a maintenance support platform is fixedly installed. A jack 3 for jacking up the coupler 1 is fixed on the maintenance support platform. The maintenance support platform raises and fixes the jack 3 to facilitate adapting to the installation height of the coupler 1 and reducing the telescopic stroke of the jack 3 during use.

[0018] One end of the maintenance support plate 2 is provided with moving rollers 4, and some of the moving rollers 4 are located outside the maintenance support plate 2. A pushing handle 5 and a hand rod sleeve 6 are also fixedly installed on the maintenance support plate 2. An operating hand rod 8 for sleeving and cooperating with the handle sleeve 7 of the jack 3 is partially inserted into the hand rod sleeve 6. The pushing handle 5 is arranged in a T-shaped structure and is inclined on the maintenance support plate 2. The hand rod sleeve 6 is fixed on the outer wall of the pushing handle 5, such as being arranged at the rear side of the pushing handle 5. When using the jack 3 to lift the coupler 1, the operating hand rod 8 needs to be taken out of the hand rod sleeve 6 and inserted into the handle sleeve 7, and the operating hand rod 8 is repeatedly operated up and down to realize the telescopic control of the jack 3. After use, the operating hand rod 8 is pulled out of the handle sleeve 7 and inserted into the hand rod sleeve 6 for storage. The operating hand rod 8 can be pressed down synchronously with the pushing handle 5 and does not occupy other positions or spaces on the maintenance support plate 2, facilitating the operation and use of the entire device.

[0019] In this embodiment, the number of movable rollers 4 is two, and two roller support plates 9 are arranged opposite to each other on the maintenance support plate 2 corresponding to each movable roller 4. The movable roller 4 is arranged between the two corresponding roller support plates 9 by rotating the wheel axle. When the movable roller 4 is installed in this way, when the inspection and maintenance work is carried out, the movable roller 4 does not contact the ground, while the maintenance support plate 2 contacts the ground, thereby improving the stability of the support of the jack 3; and when the position needs to be transferred after the inspection and maintenance work is completed, the pushing handle 5 is pressed down to make the maintenance support plate 2 rotate along the wheel axle until it is separated from the ground, and the movable roller 4 contacts the ground, and then the pushing handle 5 is pushed to apply force to achieve the position transfer of the entire device, and the operation is simple and convenient.

[0020] The maintenance support platform of this embodiment includes two support columns 10 arranged opposite to each other, and a support circular plate 11 is fixedly installed on the top of the two support columns 10. The jack 3 is fixed on the support circular plate 11. A gap is formed between the two support columns 10, which can be used to place some long tools, accessories, etc. During the movement of the device and when the maintenance support plate 2 rotates and tilts, the two support columns 10 can form a certain blockage for the long tools, accessories, etc. to prevent them from falling. Two additional stopper columns 12 can also be arranged opposite to each other on the maintenance support plate 2 to prevent the above-mentioned tools, accessories, etc. from falling. Of course, four vertical plates can also be arranged around the maintenance support plate 2 to form a box body to facilitate the placement of some smaller tools or component materials.

[0021] like Figure 4 As shown, when in use, the locomotive or vehicle does not need to be transferred from the track to the maintenance workshop, but the device is moved into the track, and the push handle 5 is controlled and the moving roller 4 is used to move in the track. If there are other people accompanying the cross rail in the track, they can hold the blocking column 12 to help pass, until the jack 3 is directly under the coupler 1, and the jack 3 is started to slightly lift the coupler 1 through the cooperation of the operating handle 8 and the handle sleeve 7.

[0022] The description of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for specific uses.
