Technical Field

[0001] The utility model relates to a rail vehicle, in particular to a rail lifting vehicle. Background Art

[0002] Rail cars can be used in a variety of environments. In some cases, there is a need to lift and transfer materials. Currently, most of these materials are transferred by forklifts, which requires a high space in the warehouse and is difficult to be widely used. Therefore, a liftable rail car is needed.

[0003] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a rail lift vehicle that has more industrial utilization value. Summary of the invention

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a rail lifting vehicle.

[0005] The utility model discloses a rail lifting vehicle, comprising a vehicle body frame. A driving motor is installed at the bottom of the vehicle body frame through a fixing plate. The driving motor drives a pull rod to move forward and backward. Both ends of the pull rod drive a telescopic frame to move up and down. A supporting frame is installed at the upper end of the telescopic frame.

[0006] This rail lift uses a driving motor to move the pull rod, which causes the telescopic frame to retract, thereby driving the upper support frame to move up and down. The support frame is used to place materials to achieve the purpose of lifting materials up and down.

[0007] Furthermore, a single side of the telescopic frame is composed of at least two groups of cross-connected connecting rods, one end of the two lowest connecting rods is sleeved on the pull rod, and the other end is movably connected to the bottom slot through an axis, and a guide wheel is installed at the end of the pull rod, and the guide wheel is stuck on the inner side of the bottom slot; one end of the two highest connecting rods is movably connected to the upper slot through an axis, and the other end is fixed with an upper cross bar, and guide wheels are installed at both ends of the upper cross bar, and the guide wheels are stuck on the inner side of the upper slot.

[0008] The telescopic frame is composed of crossed connecting rods. When the connecting rods are folded, the upper support frame can be driven to move upward. When the connecting rods are folded up and down, the support frame can be driven to move downward, thereby satisfying the operation of driving the material to be lifted or lowered.

[0009] Furthermore, the ends of the connecting rods are movably connected via shafts.

[0010] The connecting rods are movably connected by shafts so that the connecting rods can rotate based on the shafts.

[0011] Furthermore, a screw sleeve is provided in the middle of the pull rod, and the output shaft of the driving motor is a screw rod.

[0012] The driving motor drives the screw to rotate, and the screw sleeve is fixed on the pull rod. When the screw rotates, the screw sleeve can move forward and backward.

[0013] Furthermore, the support frame includes a cross bar welded at both ends of the upper slot, a limit plate is welded on the cross bar at the outer side of the upper slot, and a pulley is installed between the limit plate and the upper slot through a shaft.

[0014] A pulley is installed between the upper slot of the support frame and the limit plate, and the pulley facilitates the sliding movement of the material.

[0015] Through the above scheme, the present invention has at least the following advantages: this rail lifting vehicle drives the connecting rod to retract through the driving motor, and finally drives the support frame to move up and down. The support frame is used to place materials. The materials can be moved to the placement position after being lifted, thereby improving the efficiency of material transportation, and the transfer of materials can be completed through a set of tracks, effectively saving warehouse space.

DETAILED DESCRIPTION

[0021] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] See also Figure 1 and Figure 2This rail lift has a roller installed under the body frame 1, and the roller is used in conjunction with a guide rail installed on the foundation. There is a horizontal fixed plate on the body frame 1, and a drive motor 2 is fixedly installed on the fixed plate. When the drive motor 2 is working, it drives the pull rod 3 to move inward. When the pull rod 3 is pulled, it drives the telescopic frame to perform a telescopic operation, thereby driving the support frame 4 to move up and down, thereby achieving the purpose of driving the material up and down.

[0023] See also Figure 2 The power of this telescopic frame is provided by a driving motor 2, which drives the pull rod 3 to move inward. There are guide wheels at both ends of the pull rod 3, which are inserted into the bottom slot 6. The lower end of a connecting rod 5 is movably installed on the tail end of the bottom slot 6 through an axis. When the pull rod 3 moves inward, the two connecting rods 5 at the lower end are retracted, which also drives the upper pull rod 5 to retract. One side of the upper pull rod 5 is also movably connected to the tail end of the upper slot 7. An upper cross bar 8 is fixed to the upper end of the pull rod 5 on the other side. The two ends of the upper cross bar 8 are installed at the front end of the upper slot 7 through guide wheels, and cooperate between the pull rods 3 to drive the upper support frame 4 to move, thereby completing the purpose of driving the material up and down.

[0024] The connecting rods 5 are movably connected through shafts, so that all the connecting rods 5 are connected and the linkage between all the connecting rods 5 is achieved.

[0025] There is a screw 10 on the output shaft of the driving motor 2, and the fixed screw sleeve 9 on the pull rod 3 cooperates with the screw 10. When the driving motor 2 rotates, the screw sleeve 9 can be driven to move, thereby driving the pull rod 3 to move.

[0026] The upper cross bar 13 of the left support frame 4 is used to install the upper slot 7 and the limit plate 11. Pulleys 12 are movably installed between the upper slot 7 and the limit plate 11 through an axis. These pulleys 12 are used to support the material plate to facilitate the forward and backward movement of the material plate.
