It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. In the description of the present invention, it is to be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. In addition, in the description of the present invention, "a plurality" means two or more unless specifically limited otherwise.

Example 1: please refer to fig. 1-4;

the utility model provides a following technical scheme: a movable turnover working vehicle for multi-side maintenance of locomotive parts comprises a chassis 1, wherein the lower part of the chassis 1 is provided with a movable travelling wheel 6 for the chassis 1, and two ends of the upper surface of the chassis are respectively provided with a vertical upright post 2; a frame workbench 3 for installing locomotive components to be overhauled is connected between the two upright posts 2; two ends of the frame workbench 3 are fixedly connected with the vertical positioning plates 8 respectively, the outer side of each vertical positioning plate 8 is fixedly connected with a rotating shaft 81, and the rotating shaft 81 is inserted in a shaft hole 21 preset in the upper part of the upright post 2 and used for the frame workbench 3 to rotate;

and a positioning locking device 4 is connected between the upright post 2 and the positioning vertical plate 8 on at least one side of the upright post, and is used for limiting the rotation of the frame workbench 3 to position the frame workbench 3 when the frame workbench 3 rotates to a preset position. In the embodiment, one-side positioning is adopted, and certainly, positioning locking devices 4 are arranged on two sides, so that the fixing is more reliable, but the operation is not as convenient as one-side positioning.

Therefore, the working vehicle can move, and is convenient to transfer among different stations; the workbench can also be rotated, so that the locomotive component to be overhauled can be operated at multiple angles conveniently; and can be positioned, thereby being fixed after being rotated by one operator, freeing both hands to carry out the maintenance operation of locomotive parts.

The positioning and locking device 4 of this embodiment is positioned at one side, and then at least one of the positioning vertical plates 8 at one side is provided with a plurality of positioning holes 82 which are uniformly distributed circumferentially and centered on the rotating shaft 81; a bolt hole 22 which is transversely penetrated is formed in the upright post 2 on the same side with the positioning vertical plate 8 with the positioning hole 82;

the positioning and locking device 4 comprises a bolt component 41; one end of the latch assembly 41 is inserted into both the latch hole 22 and the positioning hole 82 to restrict the frame table 3 from rotating to be positioned.

To facilitate the grasping operation, the latch assembly 41 includes a latch head 411 for simultaneously inserting the latch hole 22 and the positioning hole 82, one end of the latch head 411 is attached to the center of the connecting plate 412, and the other side of the connecting plate 412 is attached to the handle 413.

So far, location locking device 4 is separable with stand 2, and after extracting bolt subassembly 41 at every turn, alignment is swift convenient inadequately when inserting bolt hole 22 once more, removes simultaneously to the spacing of frame workstation 3 and also need not let bolt head 411 break away from bolt hole 22, and only need let bolt head 411 break away from locating hole 82 can.

Thus, for more convenient and quick operation of the latch assembly 41, the positioning and locking device 4 further comprises a spring 42; the spring 42 is sleeved on the plug head 411, and two ends of the spring respectively support the side wall of the upright post 2 and a blocking part preset in the middle of the plug head 411, so as to drive the tail end of the plug head 411 inserted in the plug hole 22 to move towards the positioning vertical plate 8 through the elastic force of the spring 42. The positioning and locking device 4 and the upright post 2 are inseparable at the moment, the bolt assembly 41 does not need to be pushed in operation, the tail end of the bolt head 411 is already supported on the positioning vertical plate 8 in a normal state, and only when the positioning hole 82 rotates to a position coaxial with the bolt hole 22, the tail end of the bolt head 411 is automatically inserted into the positioning vertical plate under the action of the spring 42, so that the operation is more convenient and faster.

The blocking member may be a nut, a retainer ring, or a projection welded to the middle of the plug head 411. Illustratively, the blocking member of this embodiment is a pin 414 transversely inserted through the middle of the latch head 411, and one end of the spring 42 is supported against the pin 414 and extends out of the side wall of the latch head 411.

It can be noted that it is laborious and inconvenient to pull the handle 413 of the latch assembly 41 all the time to overcome the spring force when the frame table 3 is rotated. For convenience, the positioning and locking device 4 further comprises a top rod 43; one end of the top rod 43 is connected to one end of the connecting plate 412, and the other end faces the upright 2, so that when the latch assembly 41 is rotated to support one end of the top rod 43 on the side wall of the upright 2, the end of the latch head 411 is disengaged from the positioning hole 82 to release the positioning of the frame work table 3. On the contrary, when the position limitation is needed, the ejector rod 43 is rotated to the side surface of the upright post 2, and the bolt component 41 can recover to work.

In order to make the push rod 43 adjustable, the push rod 43 includes a screw thread at one end for connecting the end of the push rod 43 with the connecting plate 412 through a screw thread. The top rod 43 is thus articulated and adjustable in length so as to adjust the distance between the end of the latch head 411 when retracted and the vertical plate 8 in which it is positioned.

When in use, a locomotive component to be overhauled is mounted on the frame workbench 3 in advance through bolts through a plurality of bolt holes 31 which are pre-arranged on the frame workbench 3 and fixedly connected with the frame workbench into a whole; that is, when the frame table 3 rotates, the motorcycle part rotates. Then, pulling the handle 413 to overcome the spring force, so that the latch head 411 side is separated from the positioning hole 82, the limit of the frame work table 3 is released, and rotating the handle 413 to enable one end of the push rod 43 to be supported on the upright post 2, thereby releasing the two hands; after the frame workbench 3 is rotated to another angle, the bolt hole 22 at the position is coaxially superposed with the positioning hole 82; the handle 413 is rotated reversely again to make the push rod 43 located at the side of the upright 2, and the end of the pin head 411 is driven to insert into the positioning hole 82 by the elastic force of the spring 42 to complete the positioning. The above operations can be repeated in the process of maintenance, so that the locomotive components can be maintained at different angles.

Thus, according to the present embodiment, the following effects can be obtained:

through hollow frame workstation 3 of putting up on stand 2, adopt location locking device 4 between stand 2 and hollow frame workstation 3, realize the demand of the different angle upsets of part, reach required angle after and carry out location locking through location locking device 4, and then realize the work under the different angle, utilize the universal wheel to realize the removal of dolly again simultaneously, the removal of the part of being convenient for has increased the flexibility. The working difficulty is reduced, the working period is shortened, the overhauling efficiency is effectively improved, the quality hidden danger is avoided, and the like. In a word, this work car has simple structure, convenient operation's characteristics, is fit for popularizing and applying.
