As described in the background section, the body of a piggyback vehicle generally includes a separable tray 4 and a body 1, and the tray 4 can be separated from the body 1 during loading and unloading, so that the road vehicle can be opened and closed, and the tray 4 can be reinstalled on the body 1 after loading and unloading is completed.
In connection with fig. 1-5, for easy separation, a hooking scheme may be adopted between the supporting portion 4 and the body portion 1, the body portion 1 may be provided with a hooking structure 11, and the supporting portion 4 may be hooked in the hooking structure 11, and this connection structure, although easy to separate and install, also results in unreliable connection between the supporting portion 4 and the body portion 1 in the vertical direction, especially when the railway track has undulation, the supporting portion 4 may separate from the body portion 1 by itself, and seriously affects driving safety.
Therefore, the embodiment of the invention provides the locking mechanism 5 of the supporting part 4, which can realize the locking of the supporting part 4 and the body part 1 in the vertical direction during locking so as to ensure the reliable connection and the driving safety of the supporting part 4 and the body part 1, and does not influence the convenience of the separation of the supporting part 4 and the body part 1 during unlocking.
Specifically, the locking mechanism 5 includes: the lock body 51 is hinged, one end part of the lock body 51 is a locking end part 511, the other end part is a first limiting end part 512, the hinge shaft 52 of the lock body 51 is positioned between the locking end part 511 and the first limiting end part 512, and the hinge shaft 52 is fixedly arranged; the first limiting part 53 is fixedly arranged and can be specifically arranged on the body part 1; a drive beam assembly 54 connected to the lock body 51; in the locking state, the first limiting end portion 512 abuts against the first limiting portion 53 from top to bottom, and the locking end portion 511 abuts against the supporting portion 4 to lock the supporting portion 4; in the unlocked state, the driving beam assembly 54 can drive the first limiting end portion 512 to separate from the first limiting portion 53 from bottom to top, and the locking end portion 511 to rotate and separate from the supporting portion 4.
With this structure, as shown in fig. 4 and 5, if there is a separation trend between the supporting portion 4 and the main body portion 1 during locking, the supporting portion 4 will generate an upward force on the locking end portion 511 to drive the locking end portion 511 to rotate counterclockwise, and the supporting force generated by the first limiting portion 53 on the first limiting end portion 512 from bottom to top can block the rotation of the lock body 51 in the counterclockwise direction, so that the position of the locking end portion 511 is unchanged, and reliable locking of the supporting portion 4 can be performed; when unlocking, the driving beam assembly 54 can drive the first limiting end portion 512 to separate from the first limiting portion 53 from bottom to top, the lock body 51 can rotate clockwise, the rotation direction of the lock body is opposite to the stop direction of the first limiting portion 53, the locking end portion 511 and the supporting portion 4 can be smoothly separated, smooth unlocking of the supporting portion 4 can be achieved, and separation of the supporting portion 4 and the body portion 1 is not affected.
Here, the embodiment of the present invention is not limited to the structure of the first limiting portion 53, and may be plate-shaped or block-shaped; similarly, the number of the first limiting portions 53 is not limited in the embodiment of the present invention, and may be one or may include a plurality of independent limiting members, as long as the above-described technical effects can be achieved.
In a detailed embodiment, as shown in fig. 6, the driving beam assembly 54 may include a pushing beam 541, a guide sleeve 542 and a transmission beam 543, where the guide sleeve 542 may be fixedly disposed, specifically may be installed in the body 1 (refer to fig. 8), the pushing beam 541 may be slidably connected to the guide sleeve 542, and one end of the transmission beam 543 may be hinged to the lock body 51, and the other end may be hinged to the pushing beam 541.
Thus, when the push beam 541 is moved upwards by the driving force, the transmission beam 543 hinged to the push beam 541 can convert the linear motion of the push beam 541 into the rotational motion of the lock body 51, so as to transmit the unlocking driving force to the lock body 51, and unlock the lock body 51 can be achieved; when the driving force disappears, the pushing beam 541 can automatically slide down along the guide sleeve 542 by virtue of its own gravity and the like, and drives the lock body 51 to rotate reversely, so as to realize automatic locking of the lock body 51, and of course, the pushing beam 541 can be driven to reset and lock by the reverse driving force provided by an external device.
It should be noted that, the embodiment of the present invention is not limited to the source of the driving force applied to the push beam 541 during unlocking, and a manual driving scheme may be adopted, for example, an unlocking member such as an unlocking lever may be provided, and when unlocking is required, the unlocking member may be manually operated by a worker to generate the driving force for the push beam 541; or an automatic driving scheme can be adopted, at this time, the power sources can be motors, air cylinders, oil cylinders and the like, the power sources can be installed on a vehicle body or ground equipment, the power sources can be specifically selected according to actual conditions, and a transmission mechanism can be further arranged between the power sources and the pushing beams 541 so as to transmit the driving force of the power sources.
The beam section of the push beam 541 above the guide sleeve 542 may further be provided with a connection sleeve 541a, as shown in fig. 7, where the connection sleeve 541a may be a U-shaped plate, and a bottom plate portion of the U-shaped plate may be connected to the push beam 541 and may form a support with the guide sleeve 542, so as to serve as a limiting member 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 may be realized by the cooperation of the first limiting end 512 and the first limiting portion 53, so that the connecting sleeve 541a may not exist; or the transmission beam 543 can be used for limiting, the transmission beam 543 and the pushing beam 541 are hinged, and the transmission beam 543 and the pushing beam 541 are usually arranged in an included angle in the actual working process, and can also be used as a limiting component for downward movement of the pushing beam 541.
In the above-mentioned scheme, the transmission beam 543 converts the linear motion of the push beam 541 into the rotational motion of the lock body 51, and in fact, other schemes may be adopted besides this scheme, 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 hinge shaft of the push beam 541 may slide in the guide hole to naturally drive the lock body 51 to rotate, so that conversion from the linear motion into the rotational motion can also be achieved.
Further, an elastic member 541b may be further included, and one end of the elastic member 541b may act on the push beam 541, and the unlocking process is a process in which the deformation amount of the elastic member 541b is increased to gather elastic force. So configured, when the driving force acting on the push beam 541 is lost, the elastic force of the elastic member 541b may be released, so as to cooperate with the gravity of the push beam 541 itself to jointly drive the reset and lock of the lock body 51.
Specifically, the elastic member 541b may be a spring, which may be externally mounted to the push beam 541, and the lower end portion of the push beam 541 may be provided with a support member 541c, and both ends of the spring may respectively act on the guide sleeve 542 and the support member 541 c. The push beam 541 can act as a spring column, which is beneficial to preventing radial movement of the spring in the expansion process, and has positive effects on improving the stability of the structure and the reliability of power transmission; with this structure, in the unlocked state, the push beam 541 can be displaced upward, the elastic member 541b can be compressed, and in the restoration of the lock, the push beam 541 can be displaced downward, and the elastic member 541b can be released.
In fact, in the locked state, the elastic element 541b may have a certain pre-compression amount, that is, the elastic element 541b may still provide a certain elastic force during locking, which has a positive effect on ensuring the stability of the locked state of the lock body 51, and may avoid automatic unlocking of the lock body 51 when the railway vehicle passes through the curve.
To conveniently adjust the pre-compression amount, the support 541c may be a nut, so that the distance between the support 541c and the guide sleeve 542 may be adjusted by changing the position where the nut is screwed, and thus the pre-compression amount of the elastic member 541b in the locked state may be adjusted.
In the unlocked state, the elastic member 541b may be in a stretched state, and at this time, the installation position of the elastic member 541b may be changed, specifically, it may be disposed between the connecting sleeve 541a and the guiding sleeve 542, and both ends thereof may be fixedly connected to the connecting sleeve 541a and the guiding sleeve 542, so as to transmit the tensile force.
The lock body 51 may be provided with a mounting groove 513, and the transmission beam 543 may be hinged in the mounting groove 513, so that the thickness of the locking mechanism provided by the invention in the axial direction of the hinge shaft of the transmission beam 543 and the lock body 51 may be smaller, and the overall structure may be more compact. In addition, the mounting groove 513 may be provided in the transmission beam 543, and then the lock body 51 may be hinged in the mounting groove 513 of the transmission beam 543; alternatively, the mounting groove 513 may not be provided, and in this case, the thickness of the assembly formed by the transmission beam 543 and the lock body 51 in the axial direction of the hinge shaft between the transmission beam 543 and the lock body 51 may be relatively large.
Further, the device may further include a second limiting portion 55 fixedly provided, the second limiting portion 55 may be mounted on the body portion 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 is not repeated 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 in locking the supporting part 4.
In detail, the lock body 51 may include two locking arms disposed at an angle, the two locking arms may be formed in a substantially L shape, and the hinge shaft 52 may be disposed at a junction of the two locking arms, i.e., at a corner of the L shape, wherein an end of one locking arm away from the hinge shaft 52 may be the locking end 511, and an end of the other locking arm away from the hinge shaft 52 may be the first limiting 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 the inner end of the connection, the side where the large included angle is located is the outer end of the connection, and the outer end can be used as the second limiting end 514.
Referring to fig. 4, in the locked state, the first limiting portion 53 may generate a supporting force on the first limiting end portion 512 from bottom to top, the second limiting portion 55 may generate a supporting force on the second limiting end portion 514 from top to bottom, and then the supporting portion 4 is matched with an upward pushing force generated by the locking end portion 511, so that the stress of the lock body 51 may be more balanced; moreover, by the interaction of the three stress points, the hinge shaft 52 is substantially in an unstressed state, which has a positive effect on ensuring the reliability of the locking mechanism.
The locking mechanism provided by the invention can be installed on the body part 1, besides the installation supporting points formed by the guide sleeve 542, the first limiting part 53 and the second limiting part 55, the hinge shaft 52 can also be used as an installation supporting point, specifically, in combination with fig. 7, the outer wall of the hinge shaft 52 can be provided with a slot, the slot can be internally provided with a mounting plate 521 (the connection mode of the mounting plate 521 and the hinge shaft 52 can also be directly welded), the mounting plate 521 can be connected with the body part 1 through a connecting piece in the form of a bolt 522 and the like, and the mounting plate 521 and the body part 1 can be fixedly connected through welding and the like besides the bolt connection.
