As described in the background section, the body of a piggyback car generally comprises a separable tray 4 and a body 1, and the tray 4 can be separated from the body 1 to facilitate the opening and closing of a road vehicle when loading or unloading is performed, and the tray 4 can be remounted on the body 1 after the loading or unloading is completed.

With reference to fig. 1-5, for the convenience of separation, a hanging scheme may be adopted between the support portion 4 and the main body portion 1, the main body portion 1 may be provided with a hook structure 11, and the support portion 4 may be hung in the hook structure 11, such a connection structure, although convenient for separation and installation, may also cause the unreliable vertical connection between the support portion 4 and the main body portion 1, and especially when the railway track has undulation, the support portion 4 may be separated from the main body portion 1 by itself, which may seriously affect the driving safety.

Therefore, the embodiment of the utility model provides a locking mechanism 5 of support portion 4, when the locking, can realize support portion 4 and this somatic part 1 locking on the vertical to guarantee the two reliable connection and driving safety, when the unblock, do not influence the convenience of support portion 4 and this somatic part 1 separation again.

Specifically, the locking mechanism 5 includes: the lock comprises a lock body 51 which is hinged, wherein one end of the lock body 51 is a locking end 511, the other end of the lock body 51 is a first limiting end 512, a hinge shaft 52 of the lock body 51 is positioned between the locking end 511 and the first limiting end 512, and the hinge shaft 52 is fixedly arranged; a first limit part 53 fixedly arranged, which can be specifically installed on the body part 1; a drive beam assembly 54 connected to the lock body 51; in the locked state, the first limiting end 512 abuts against the first limiting part 53 from top to bottom, and the locking end 511 abuts against the support part 4 to lock the support part 4; in the unlocked state, the driving beam assembly 54 can drive the first limiting end 512 to be separated from the first limiting part 53 from bottom to top, and the locking end 511 is rotated to be separated from the support part 4.

With such a structure, as shown in fig. 4 and 5, when locking, if there is a separation trend between the holder 4 and the main body 1, the holder 4 will generate an upward force on the locking end 511 to drive the locking end 511 to rotate counterclockwise, and due to the bottom-up supporting force generated by the first limiting part 53 on the first limiting end 512, the lock body 51 can be blocked from rotating counterclockwise, so as to ensure that the position of the locking end 511 is not changed, and the holder 4 can be reliably locked; when the lock is unlocked, the driving beam assembly 54 can drive the first limiting end 512 to be separated from the first limiting part 53 from bottom to top, the lock body 51 can rotate clockwise, the rotating direction of the lock body is opposite to the stopping direction of the first limiting part 53, the locking end 511 and the supporting part 4 can be separated smoothly, the smooth unlocking of the supporting part 4 can be realized, and the separation of the supporting part 4 and the body part 1 is not influenced.

Here, the embodiment of the present invention is not limited to the structure of the first stopper 53, and may be plate-shaped or block-shaped; similarly, the embodiment of the present invention does not limit the number of the first limiting portions 53, and the number of the first limiting portions may be one, or may include a plurality of mutually independent limiting portions, as long as the above technical effects can be achieved.

In a detailed embodiment, as shown in fig. 6, the driving beam assembly 54 may include a push beam 541, a guiding sleeve 542, and a driving beam 543, wherein the guiding sleeve 542 may be fixedly disposed, and specifically, may be installed in the body portion 1 (refer to fig. 8), the push beam 541 and the guiding sleeve 542 may be slidably connected, one end of the driving beam 543 may be hinged to the lock body 51, and the other end may be hinged to the push beam 541.

Thus, when the push beam 541 is moved upwards by a driving force, the transmission beam 543 hinged thereto may convert the linear motion of the push beam 541 into a rotational motion of the lock body 51, so as to transmit the unlocking driving force to the lock body 51, thereby unlocking the lock body 51; when the driving force disappears, the push beam 541 can automatically slide down along the guide sleeve 542 by means of its own gravity, and drive the lock body 51 to rotate in the reverse direction, so as to realize the automatic locking of the lock body 51, or the external device can provide the reverse driving force to drive the push beam 541 to reset and lock.

It should be noted that the embodiment of the present invention does not limit the source of the driving force received by the push beam 541 during unlocking, and the push beam 541 may be driven manually, for example, an unlocking member such as an unlocking lever may be provided, and when unlocking is required, the unlocking member may be operated manually by a worker to generate the driving force for the push beam 541; or, an automatic driving scheme may also be adopted, in this case, the power source may be a motor, an air cylinder, an oil cylinder, or the like, the power source may be mounted on the vehicle body, or may be mounted on the ground equipment, which may be specifically selected according to the actual situation, and a transmission mechanism may also be disposed between the power source and the push beam 541 to transmit the driving force of the power source.

The beam section of the push beam 541 above the guiding sleeve 542 may further be provided with a connecting sleeve 541a, as shown in fig. 7, the connecting sleeve 541a may be a U-shaped plate, a bottom plate portion of the U-shaped plate may be connected with the push beam 541 and may form a support with the guiding sleeve 542 to serve as a limiting component for downward movement of the push beam 541, and the transmission beam 543 may be hinged between two side plate portions of the U-shaped plate.

In fact, the downward movement limitation of the push beam 541 can also be realized by the cooperation of the first limitation end 512 and the first limitation portion 53, so that the connection sleeve 541a can also be absent; alternatively, the driving beam 543 may be used for limiting, the driving beam 543 and the pushing beam 541 are hinged, and the driving beam 543 and the pushing beam 541 are usually disposed at an included angle in the actual working process, and the driving beam 543 may also be used as a limiting component for downward movement of the pushing beam 541.

In the above-mentioned solution, the linear motion of the push beam 541 is converted into the rotational motion of the lock body 51 through the transmission beam 543, and in fact, other solutions may be adopted besides this solution, for example, a guide hole may be provided on the lock body 51, the push beam 541 may be hinged in the guide hole, and when the push beam 541 generates an axial displacement, the hinged shaft of the push beam 541 may slide in the guide hole to naturally drive the lock body 51 to rotate, so that the conversion from the linear motion to the rotational motion may also be realized.

Further, an elastic member 541b may be further included, and one end of the elastic member 541b may interact with the push beam 541, and the unlocking process is a process of increasing a deformation amount of the elastic member 541b to gather an elastic force. With this arrangement, when the driving force applied to the push beam 541 disappears, the elastic force of the elastic member 541b can be released to cooperate with the gravity of the push beam 541 itself to drive the lock body 51 to be reset and locked.

Specifically, the elastic member 541b may be a spring, which may be externally sleeved on the push beam 541, and a supporting member 541c may be disposed at a lower end of the push beam 541, and both ends of the spring may respectively interact with the guide sleeve 542 and the supporting member 541 c. The push beam 541 can serve as a spring column, so that the radial movement of a spring in the expansion process can be prevented, and the positive effects of improving the structural stability and the power transmission reliability are achieved; with this structure, the push beam 541 can be displaced upward and the elastic member 541b can be compressed in the unlocked state, and the push beam 541 can be displaced downward and the elastic member 541b can be released when the locking is restored.

In fact, in the locked state, the elastic member 541b may have a certain pre-compression amount, that is, the elastic member 541b may still provide a certain elastic force when being locked, which has a positive effect on ensuring the stable locked state of the lock body 51, and may avoid the automatic unlocking of the lock body 51 when the rail vehicle passes through a curve.

To conveniently adjust the pre-compression amount, the supporting member 541c may be a nut, so that the distance between the supporting member 541c and the guide sleeve 542 can be adjusted by changing the screwing position of the nut, and thus the pre-compression amount of the elastic member 541b in the locked state can be adjusted.

In the unlocked state, the elastic member 541b may be actually in a stretched state, and the installation position of the elastic member 541b may be changed, and specifically, the elastic member may be disposed between the connection sleeve 541a and the guide sleeve 542, and both ends of the elastic member may be fixedly connected to the connection sleeve 541a and the guide sleeve 542 so as to transmit the pulling force.

The lock body 51 can be equipped with mounting groove 513, and transmission roof beam 543 can articulate in this mounting groove 513, like this, the utility model provides a locking mechanism can be less at the transmission roof beam 543 with the epaxial thickness of the articulated shaft of lock body 51, overall structure can be more compact. Besides, the installation groove 513 can be arranged in the transmission beam 543, and then the lock body 51 can be hinged in the installation groove 513 of the transmission beam 543; alternatively, the installation groove 513 may not be provided, and in this case, the thickness of the assembly formed by the driving beam 543 and the lock body 51 in the axial direction of the hinge shaft of the driving beam 543 and the lock body 51 may be relatively large.

Further, a second limiting portion 55 may be further included, the second limiting portion 55 may be mounted on the main body 1, and the structure and the like of the second limiting portion 55 may be similar to those of the first limiting portion 53, which will not be described repeatedly herein; the lock body 51 may further include a second limiting end 514, and in the locked state, the second limiting end 514 may abut against the second limiting portion 55 from bottom to top.

In this way, in the locked state, the lock body 51 can form a three-point supporting scheme, the stress of the lock body 51 is more balanced, and the lock body 51 is more reliable for locking the support part 4.

In detail, the lock body 51 may include two angled lock arms, which may form a substantially L-shape, and the hinge shaft 52 may be disposed at a connection point of the two lock arms, i.e., a corner of the L-shape, wherein an end of one lock arm away from the hinge shaft 52 may be the lock end 511, and an end of the other lock arm away from the hinge shaft 52 may be the first limit end 512; a small included angle (<180 degrees) and a large included angle (>180 degrees) are formed between the two locking arms, wherein the side where the small included angle is located is an inner end portion of the connection, the side where the large included angle is located is an outer end portion of the connection, and the outer end portion can be used as the second limiting end portion 514.
