From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects:
when the railway rotary piggyback transport vehicle is used for loading and unloading a highway truck or a semitrailer, the concave underframe needs to be rotated out for loading and unloading, and after the loading and unloading are completed, the concave underframe is rotated back to the original position, so that the concave underframe is prevented from rotating over and falling off the slideway.
The scheme of the invention is mainly a positioning device which mainly comprises a positioning collision head, a guide support, a spring, a tension spring seat, a driving plate, a fixing plate 27, a vertical plate 26, a first rib plate, a second rib plate and the like. The direction support welding is on the tip chassis, and the guiding hole in the middle of the direction support is the quad slit for the flexible removal and the installation of head are met in the location, and fixed plate 27 is "second" font board, and one end welding is on the tip chassis, and the other end and the cooperation of riser 26 form the mounted position of drive plate, and first gusset and second gusset welding improve structural strength and rigidity on the fixed plate. One of the two tension spring seats is welded on the guide support, and the other tension spring seat is welded on the driving plate.
One end of the driving plate is provided with a strip-shaped hole which is connected with the positioning collision head by a pin shaft and the like, the middle hole is provided with a tension spring seat, and the other hole is used for being connected with the vertical plate and the fixing plate and used as a rotating fulcrum of the driving plate. The driving plate can rotate around the vertical plate and the pin shaft of the fixing plate, the pin shaft at the strip-shaped hole drives the positioning collision head to stretch, and the spring plays a role in resetting.
The positioning collision head comprises a stopping portion 211 and a telescopic portion 212, a mounting hole connected with the drive plate is formed in the stopping portion 211, the telescopic portion 212 is of a square cross-section structure, correspondingly, the guide hole is a square hole, and the part can be guided to stretch in the square hole of the support. When the concave underframe is limited in rotation, the square section part of the positioning collision head is a contact part, so that the concave underframe is prevented from falling out from the end underframe.
The guide supports are welded to the end underframe as the main stressed components, which ensure sufficient strength and rigidity. The protruding end of the guide support is provided with a collision head telescopic hole and a tension spring seat mounting hole.
The working principle of the positioning device is as follows: the positioning collision head is positioned at the normal working position, the spring is provided with a certain initial pretightening force, the positioning collision head extends out of the end surface of the guide support, and the limiting concave bottom frame rotates out. When the concave underframe is used for loading and unloading highway cargos, the end underframe lifting device descends, the movable sliding table descends and rotates, the movable sliding table baffle plate extrudes the drive plate, the drive plate rotates around the rotating point to drive the positioning collision head to retract, and the concave underframe can rotate out. When the loading and unloading are completed, the movable sliding table is rotated back, the movable sliding table baffle plate is separated, the driving plate is restored to the initial state under the action of the spring force, the positioning collision head extends out of the guide support, and the concave bottom frame is limited to rotate out again.
When the piggyback transport vehicle is in a normal state, the rotary positioning device of the concave underframe is in a limiting state, and at the moment, the concave underframe can not be rotated out, so that the operation safety is ensured. When loading and unloading highway freight train or semitrailer, tip chassis plays to rise the device and descends, removes the slip table decline simultaneously, and the concave chassis needs the removal slip table of roll-out side to roll out, and at this moment, removes the slip table baffle extrusion drive plate, makes the drive plate drive the location and meets the head and withdraw, and concave chassis can follow this side and roll out, and opposite side positioner still is in limit state, can not roll over the position and fall out the tip chassis when guaranteeing concave chassis to roll back. When the loading and unloading are completed, the concave underframe is rotated back, the rotated movable sliding table is rotated back, the driving plate is restored to the initial state, the positioning collision head extends out, the concave underframe is limited to rotate again, and the end underframe lifting device lifts. The piggyback car returns to the normal state.
The scheme of the invention is a concave underframe rotary positioning device, which is matched with other mechanical mechanisms to automatically realize unlocking and limiting in the loading and unloading process of a piggyback transport vehicle, and has simple and reliable structure, high operation efficiency and good popularization value.
