The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

The rail transporting vehicle is the largest vehicle type in the long steel rail transport vehicle set and is used for bearing steel rails. The rail transport vehicle is provided with a plurality of groups of roller doors, and each group of roller doors comprises two roller door stand columns and a plurality of roller path beams which are oppositely arranged. The roller path beam is rotatably connected with the roller door upright post from top to bottom in sequence. When the roller way beam is in a working position, the roller way beam spans between the two roller door upright posts and can bear a plurality of steel rails. When no steel rail is arranged on the raceway beam, the raceway beam rotates to a non-working position parallel to the length direction of the vehicle body. In order to prevent the raceway beams from swinging and being damaged during the operation of loading and unloading long steel rails, the rail transport vehicle is also provided with a locking device for locking the raceway beams in an operating position and a non-operating position.

When the rail transport vehicle is used for carrying out rail loading operation in a rail plant, workers need to unlock the raceway beams at a non-working position, then push the raceway beams to rotate to a working position, and lock the raceway beams at the working position, and after the raceway beams at the same layer of all the rail transport vehicles are located at the working position and locked, steel rails can be placed on the raceway beams at the layer. Similarly, during rail unloading operation, after a certain layer of steel rails are completely unloaded, workers need to unlock all the raceway beams on the layer at the working positions of the raceway beams on the layer, then push the raceway beams to rotate to the non-working positions, then lock the raceway beams at the non-working positions, and then unload the steel rails on the raceway beams on the next layer.

The raceway beam is an important structure for bearing steel rails on the rail transport vehicle. In order to prevent the offset and the unbalance loading caused by the offset in the steel rail transportation process, the raceway beams are provided with a steel rail spacing device for spacing the steel rails. The rail-transporting vehicle is usually provided with a rail-spacing device only at one roller door, preferably a roller door arranged in the middle. Obviously, in order to better achieve the effect of spacing the rails, a plurality of rail spacing devices may be provided along the extension of the rails, especially when the rails are more, longer and heavier.

However, in the prior art, the steel rail spacing device is turned over and locked by operators in a manual driving mode, the workload of manual operation is large, time and labor are wasted, and the working efficiency is affected. In view of this, the present application provides an automatic spacing device.

The automatic spacing device is arranged on a rail transport vehicle and comprises a mounting base plate, a rotating shaft assembly, a driving mechanism and a blocking mechanism. The rotating shaft assembly comprises a rotating shaft which can be rotatably arranged on the mounting base plate, and a spacing structure and a shaft stop structure are fixedly arranged on the periphery of the rotating shaft; the spacing structure has an action position which is positioned between adjacent steel rails to space the adjacent steel rails and a retraction position which is far away from the steel rails in the rotating process of the rotating shaft; the position of the shaft stop structure when the shaft stop structure rotates to the action position along with the spacing structure is the first position.

The driving mechanism is arranged on the mounting substrate and comprises a first driving device for driving the rotating shaft to rotate.

The lock catch mechanism is arranged on the mounting substrate and comprises a locking structure and a second driving device for driving the locking structure to move; the locking structure has a locked state for blocking the shaft stop structure at the first position to limit the rotation of the rotating shaft during movement, and an unlocked state for releasing the blocking of the shaft stop structure to allow the spacing structure to move along with the rotating shaft from the acting position to the retracting position.

To facilitate a clear understanding of the present application, fig. 1 to 10 show a specific embodiment of an automatic spacing device. The automatic spacing device is mounted on a rail transport vehicle.

Referring to fig. 4 and 2, the automatic spacing device 1 includes a rotating shaft assembly 10, a shaft seat assembly 20, a driving mechanism 30, a blocking mechanism 60, a first mounting plate 50 and a second mounting plate 40. The first mounting plate 50 is fixedly mounted on the raceway beam 2 by bolts, and the extending direction is parallel to the extending direction of the raceway beam 2.

The spindle assembly 10 includes a spindle 101, a stop structure 103, and a spacer structure 102. The rotating shaft 101 is a shaft-like structure extending parallel to the raceway beam 2, and is rotatably mounted on the first mounting plate 50 via the shaft seat assembly 20. The periphery of the rotating shaft 101 is provided with a plurality of spacing structures 102 extending from the rotating shaft 101 along a direction perpendicular to the extending direction of the rotating shaft 101, and the spacing structures 102 are arranged corresponding to the spacing positions between the steel rails arranged side by side on the raceway beams 2. The spacing structures 102 are located between adjacent steel rails when being turned up to the position vertically above the rotating shaft 101 along with the rotation of the rotating shaft 101, and can be used for spacing the steel rails to prevent the steel rails from deviating in the transportation process to cause unbalance loading. This position is called the action position. The spacer 102 is rotated with the shaft 101 to move down and away from the rail, facilitating the loading and unloading of the rail, this position being referred to as the stowed position. In this embodiment, the rotation range of the rotating shaft 101 is 90 degrees, and the stowing position, i.e. the spacing structure 102 moves to the horizontal position. Obviously, as the rotation range of the rotating shaft 101 changes, the retracting position also changes, and the spacing structure 102 in the retracting position does not affect the loading and unloading of the steel rail.

As can be seen from fig. 5, the shaft stop structure 103 is disposed at a position near one end of the rotating shaft 101, and the spacing structure 102 is disposed at opposite sides of the outer periphery of the rotating shaft 101. The extending directions of the shaft stop structure 103 and the spacing structure 102 are perpendicular to the extending direction of the rotating shaft 101 and parallel to each other. When the spacing structure 102 moves with the rotating shaft 101 to the acting position, the position of the shaft stop structure 103 is referred to as a first position, and as shown in fig. 10, the shaft stop structure 103 in the first position is located vertically below the rotating shaft 101. As can be seen from the above description, when the spacer structure 102 is moved to the retracted position, the shaft stopper structure 103 is also moved to the horizontal position. The positions of the axle stop structure 103 and the spacer structure 102 relative to the rotating shaft 101 can be adjusted, but the axle stop structure 103 should be located at a position that does not affect the mounting and dismounting of the steel rail when the spacer structure 102 is in the retracted position.

The spacing structure 102 and the stop structure 103 are disposed on the rotating shaft 101 by welding. Obviously, the spacing structure 102 and the stop structure 103 may be mounted on the rotating shaft 101 by a connection method known to those skilled in the art, such as a threaded connection, an interference fit in a mounting groove formed on the rotating shaft 101, and the spacing structure 102 and the stop structure 103 may also be integrally formed with the rotating shaft 101.

Please refer to fig. 6 and 7. The axle seat assembly 20 includes a base 202 and a seat cover 201. The base 202 is fixed to the first mounting plate 50 by bolts and has a first through-hole. The seat cover 201 is provided on the top of the base 202 and has a second through-groove facing the first through-groove. When the seat cover is installed, the base 202 and the seat cover 201 are fastened by bolts, the first through groove and the second through groove are spliced to form a cylindrical rotating cavity 203, the rotating cavity 203 surrounds the periphery of the rotating shaft 101, and the rotating shaft 101 can rotate in the rotating cavity 203. As can be seen from fig. 4, the automatic spacing device 1 is provided with the same number of shaft seat assemblies 20 as the spacing structures 102, the shaft seat assemblies 20 are arranged in one-to-one correspondence with the spacing structures 102, and the bearing assemblies are arranged near the spacing structures 102 corresponding to the rotating shafts 101. With this arrangement, the weight of the rotating shaft 101 and the spacing structure 102 can be effectively supported while the rotating shaft 101 is supported to rotate. In some other embodiments, the shaft seat assemblies 20 may be uniformly distributed along the extending direction of the rotating shaft 101.

Referring to fig. 4 and 8, the driving mechanism 30 is disposed at the other end of the rotating shaft 101 opposite to the axle stop structure 103, and includes a rotating cylinder, a universal joint 301, and a second mounting plate 40. The second mounting plate 40 is fixed to the raceway beams 2 by welding. The first mounting plate 50 and the second mounting plate 40 are collectively referred to as a mounting substrate. In this embodiment, the first mounting plate 50 and the second mounting plate 40 may be plate-shaped structures separately provided, and in other alternative embodiments, the two may be an integral structure. The rotary oil cylinder is fixed on the second mounting plate 40 through bolts, and the output shaft is parallel to and staggered with the extending direction of the rotating shaft 101. A universal coupling 301 is arranged between the rotating shaft 101 and the rotating cylinder, and two ends of the universal coupling 301 are connected with the rotating oil cylinder and the rotating shaft 101 through keys.

When the steel rail spacing structure is used, the hydraulic system provides power to enable the rotary oil cylinder to rotate in the forward direction, the rotating shaft 101 rotates in the forward direction through the universal coupling 301, and in the rotating process, the spacing structure 102 is turned up from the retracting position to the acting position located between adjacent steel rails, so that spacing of the steel rails is achieved. After the work is finished, the hydraulic system provides power to enable the rotary oil cylinder to rotate reversely, the rotating shaft 101 is enabled to rotate reversely through the universal coupling 301, and the spacing structure 102 is turned down from the acting position to the retracting position far away from the steel rail. In the present embodiment, the rotation is forward rotation, i.e., clockwise rotation in fig. 10, and the rotation is reverse rotation, i.e., counterclockwise rotation.

It should be noted that although the forward rotation in the present embodiment is a clockwise rotation, the forward rotation and the reverse rotation are only for indicating that the two rotation directions are opposite, and do not refer to a specific direction of rotation.

The catch mechanism 60 includes a hydraulic cylinder 601 and a locking structure. The locking structure includes a fixed stop 604 and a movable stop 603. As shown in fig. 9 and 10, the fixed stopper 604 is mounted on the first mounting plate 50 at a right position of the shaft stopper structure 103 at the first position, i.e., at a forward position of forward rotation, so as to prevent the rotating shaft 101 from further forward rotation by the shaft stopper structure 103.

The hydraulic cylinder 601 is fixed to the first mounting plate 50, and the rotating shaft 101 and the hydraulic cylinder 601 are respectively located above and below the first mounting plate 50. The hydraulic cylinder 601 comprises a piston rod 602, and the piston rod 602 is moved by the hydraulic cylinder 601 in a direction parallel to the extending direction of the rotating shaft 101. The first mounting plate 50 is provided with a through guide groove extending in a direction parallel to the extending direction of the rotating shaft 101. The movable stopper 603 is connected to the piston rod 602 by a screw thread, and extends from the guide groove to above the first mounting plate 50. The movable stop 603 during the movement of the piston rod 602 may be moved to the left position of the stopper structure 103 in the first position, i.e. the rear position of the forward movement. The movable stop 603 and the fixed stop 604 cooperate to stop the shaft stopper structure 103 and limit the rotational movement of the shaft stopper structure 103, so as to limit the rotation of the rotating shaft 101 and the spacer structure 102, so as to stably and reliably maintain the spacer structure 102 at the acting position, and the state of the locking mechanism 60 is referred to as a locking state.

When the movable stopper 603 moves away from the left position of the shaft stopper structure 103 in the first position under the driving of the piston rod 602, the locking of the shaft stopper structure 103 is released, and the rotating shaft 101 can freely move in the opposite direction, i.e. the spacer structure 102 can move from the acting position to the retracted position. The state of the catch mechanism 60 at this time is referred to as an unlocked state.

Obviously, when the arrangement relationship between the spacing structure 102 and the shaft stopper structure 103 and the rotation direction of the rotating shaft 101 are changed, the arrangement positions of the fixed stopper 604 and the movable stopper 603 are also changed adaptively. In summary, the following conditions are satisfied: the fixed stopper 604 is disposed at a position forward in the moving direction of the stopper structure 103 at the first position, and the movable stopper 603 is driven by the hydraulic cylinder 601 to be close to and away from a position rearward in the moving direction of the stopper structure 103 at the first position.

As another embodiment of the locking mechanism, the catch mechanism 60 includes a second drive device and a locking structure that includes a U-shaped structure relative to the first and second striker plates. When the locking structure is moved close to the axle stop structure 103 in the first position by the second driving means, the first and second shutters may be moved to the left and right positions of the axle stop structure 103 in fig. 10. The first baffle and the second baffle cooperate to block the blocking structure 103, so as to limit the rotational movement of the blocking structure 103, and therefore the rotation of the rotating shaft 101 and the spacing structure 102, so as to stably and reliably maintain the spacing structure 102 at the acting position, and the state of the blocking mechanism 60 is referred to as a locking state. When the locking structure moves away from the shaft stopper structure 103 located at the first position under the driving of the second driving device, the locking of the shaft stopper structure 103 is released, the rotating shaft 101 can rotate freely, that is, the spacer structure 102 can move from the acting position to the retracted position, and at this time, the state of the lock mechanism 60 is referred to as an unlocked state.

As another embodiment of the locking mechanism, the catch mechanism 60 includes a locking structure that is swingably mounted to the second mounting plate 40, the locking structure moving between a locked state and an unlocked state during swinging, and a second drive means.

The hydraulic system has small volume and light weight; the driving force is large, and the hydraulic cylinder 601 is adopted as a first driving device and the rotary cylinder is adopted as a second driving device in the embodiment, so that the hydraulic cylinder is suitable for heavy-load direct driving and the like. Obviously, the first driving device and the second driving device can also adopt motors.

The automatic spacing device 1 further comprises a controller for controlling the movement of the first and second driving means and a remote control. The remote controller is provided with an operating device for inputting an operating instruction by a user, is in signal connection with the controller in a wired or wireless mode, transmits a control instruction to the controller, and controls the first driving device and the second driving device to work. The automatic spacing device 1 can be controlled by a remote controller in the operation process, so that an operator can remotely operate at a safe position to eliminate potential safety hazards; and can control the spacer of a plurality of cars simultaneously through electronic technology, raise the efficiency, labour saving and time saving.

As shown in fig. 1 to 3, in this embodiment, the automatic spacing device 1 is disposed on the raceway beam 2, so that the limited space on the raceway beam 2 can be reasonably utilized, the function of spacing the rails is realized, and the structure is reasonable and reliable. As a further alternative, the automatic spacing device 1 is a device separate from the raceway beams 2. The first mounting plate 50 and the second mounting plate 40 are of an integral structure and are disposed between the roller door columns.

The automatic spacing device 1 is the same as the raceway beams 2, is rotatably arranged between the roller door columns, has a working position spanning between the two roller door columns, and rotates to a non-working position parallel to the length direction of the vehicle body. In order to prevent the automatic distancing means 1 from swinging and damaging during the operations of loading and unloading long rails, the rail transport vehicle is also provided with locking means for locking the automatic distancing means 1 in the operative position and in the inoperative position. In the embodiment in which the automatic distancing means 1 are provided on the raceway beams 2, the automatic distancing means 1 and the raceway beams 2 share the same locking means. In the embodiment in which the automatic spacing device 1 is provided separately from the raceway beams 2, the automatic spacing device 1 is provided with a locking device separately with reference to the raceway beams 2.

The invention also provides an embodiment of the rail transport vehicle, which comprises the automatic spacing device in the embodiment.
