Description

Technical Field

[0001] The present invention relates to the technical field related to the unloading and loading of steel rails, and particularly to an automatic steel rail lifting device. Background Art

[0002] When the long steel rail transport vehicle group unloads a single layer of steel rails or simultaneously performs the operations of unloading and loading rails (while unloading a new layer of steel rails, the old rails are received on the second layer), the steel rails on the first layer will be lifted upward along a certain transition curve, thus interfering with the rail ends of the steel rails on the second layer or the rolling beam on the second layer. Since the kinetic energy of the steel rails is relatively large during rail unloading, the impact friction will seriously damage the surface of the steel rails and the steel structure of the rolling beam, causing economic losses and posing certain safety hazards.

[0003] When the existing long steel rail transport vehicle group unloads rails, it adopts the method of unloading rails layer by layer, that is, first unloads the steel rails on the second layer, and after unloading, the rolling beam on the second layer is opened, and then the steel rails on the first layer are unloaded.

[0004] The operation method that cannot unload a single layer of steel rails or simultaneously perform the operations of unloading and loading rails, and when storing the old rails on the second layer, it is necessary to first unload the steel rails on the second layer before continuing to unload the new rails on the first layer. After the rail unloading is completed, the old rails on the ground also need to be collected, which greatly increases the time cost and labor cost. Summary of the Invention

[0005] The present invention aims to provide an automatic steel rail lifting device to solve the problem that when the long steel rail transport vehicle group unloads a single layer of steel rails or simultaneously performs the operations of unloading and loading rails, the steel rails on the first layer interfere with the rail ends of the steel rails on the second layer or the rolling beam on the second layer, improve the efficiency of rail loading and unloading, and reduce potential safety hazards.

[0006] To this end, the technical solution adopted by the present invention is: an automatic steel rail lifting device, including two columns oppositely arranged on the left and right sides of the vehicle frame. The columns include a fixed column and a rotating column. A cross beam for lifting the steel rails is arranged between the fixed column and the rotating column. A lifting structure for lifting the cross beam is arranged in each column, and a rotating structure for rotating the rotating column is arranged on the rotating column; the lifting structure includes a first driving member, a vertical pulley arranged at the output end of the first driving member, and a sliding assembly that slides up and down in the column and is arranged on the vertical pulley.

[0007] Preferably, as the above solution, the column includes a bottom plate, two sliding tracks oppositely arranged front and back on the bottom plate, and a top plate arranged at the top of the sliding tracks. A fixed seat for fixing the first driving member is arranged on the bottom plate, and the fixed seat is arranged in the middle of the two sliding tracks.

[0008] Further preferably, the vertical pulley includes two vertical plates disposed on both sides of the first driving member and a connecting cross plate disposed at the top of the vertical plates. A connecting pin for connecting the vertical plates is disposed at the output end of the first driving member. The sliding assembly includes vertical pulley shafts respectively disposed on the two vertical plates and sliding members disposed on the vertical pulley shafts for sliding up and down within the two sliding tracks.

[0009] Further preferably, the rotating structure includes a second driving member disposed below the rotating column, a rotating connecting seat connected to the output end of the second driving member, and a rotating plate disposed on the rotating connecting seat. The rotating plate is disposed on the bottom plate, and a rotating shaft for the rotation of the rotating plate is disposed on the bottom plate.

[0010] Further preferably, a first mounting seat for mounting the cross beam is disposed on the rotating column, and a second mounting seat for mounting the cross beam is disposed on the fixed column. A connecting base for bolt connection with the first mounting seat is disposed at one end of the cross beam, and the other end is connected to the second mounting seat through a placing base disposed on the second mounting seat. Both the first mounting seat and the second mounting seat are connected to the vertical plate.

[0011] Advantages of the present invention: The second-layer steel rail is lifted by the lifting structure, so that the second-layer rolling track beam can be opened, avoiding collisions caused by the second-layer steel rail end and the second-layer rolling track beam invading the unloading movement curve of the first-layer steel rail. The first-layer steel rail can be unloaded alone on the long rail transport vehicle or the rail receiving and unloading operations can be carried out simultaneously. When storing the old rails on the second layer, the new rails on the first layer can be unloaded without removing the second-layer steel rails, saving time cost and labor cost, improving the loading and unloading efficiency of the rails and reducing potential safety hazards at the same time.

[0017] The present invention will be further described below with reference to the drawings and embodiments.

[0018] AsFigures 1-5 As shown in Figures 1-5 , the automatic rail lifting device includes two columns relatively arranged on the left and right sides of the vehicle frame. Each column includes a bottom plate 6, two sliding rails 7 arranged front and back on the bottom plate 6, and a top plate 8 arranged at the top of the sliding rails 7. A fixed seat 9 for fixing the first driving member 4 is arranged on the bottom plate 6, and the fixed seat 9 is arranged between the two sliding rails 7.

[0019] The bottom plate 6 is bolted to the vehicle frame of the long rail transport vehicle, which is convenient for the disassembly and maintenance of the column. A plurality of triangular reinforcing ribs for increasing strength are arranged between the bottom plate 6 and the sliding rails 7 to ensure the strength of the sliding rails 7. The first driving member 4 is fixed by the fixed seat 9 arranged between the two sliding rails 7, which facilitates the vertical trolley 5 arranged on the first driving member 4 to slide in the sliding rails 7, and the stability of the vertical trolley 5 during up and down sliding is ensured by means of the sliding rails 7 on both sides. Among them, the first driving member 4 adopts a driving device that makes a linear reciprocating motion, such as a cylinder, an electric cylinder, a hydraulic cylinder, etc. (this is prior art and will not be elaborated here).

[0020] The sliding rails 7 adopt gantry channel steel. Gantry channel steel is a special type of channel steel, which is usually used to make forklift masts, that is, the components on forklifts responsible for fixing goods. The cross-sectional shape of this channel steel is "C", so it is also called C-shaped forklift mast channel steel. It has high strength and high rigidity and can remain stable in various working environments. At the same time, its design takes into account lightweight, effectively reducing the vehicle weight and energy consumption. The gantry channel steel has a long service life, reducing the cost of frequent replacement and maintenance, and the design takes into account the needs of maintenance and upkeep, facilitating users for daily inspection and maintenance.

[0021] The column includes a fixed column 1 and a rotating column 2. A cross beam 3 for lifting the rail is arranged between the fixed column 1 and the rotating column 2. A lifting structure for lifting the cross beam 3 is arranged inside the column. The lifting structure includes a first driving member 4, a vertical trolley 5 arranged at the output end of the first driving member 4, and a sliding assembly arranged on the vertical trolley 5 and sliding up and down inside the column.

[0022] A fixed column 1 and a rotating column 2 are provided, and a cross beam 3 is arranged between the fixed column 1 and the rotating column 2. The rotation of the rotating column 2 drives the cross beam 3 to disengage from the fixed column 1, thereby opening the cross beam 3. At this time, it is convenient for the vehicle to load the rail. When unloading the rail, the cross beam 3 is in a closed state. The cross beam 3 is driven upward by a lifting structure, and the upper-layer rail is driven by the cross beam 3 to leave the raceway beam. At this time, the upper-layer raceway beam is opened, so as to disassemble the lower-layer rail. A vertical pulley 5 and a sliding assembly are provided, so that the up and down movement of the cross beam 3 is smoother and the stability is improved. The cross beam 3 is made of H-shaped steel with the material of Q345B. H-shaped steel has a large bearing capacity and good stability. Q345B is a low-alloy high-strength steel with high strength, good plasticity and weldability, and is suitable for heavy building structures and important load-bearing components.

[0023] A rotating structure for the rotation of the rotating column 2 is arranged on the rotating column 2; the rotating structure includes a second driving member 13 arranged below the rotating column 2, a rotating connecting seat 14 connected to the output end of the second driving member 13, and a rotating plate 15 arranged on the rotating connecting seat 14. The rotating plate 15 is arranged on the bottom plate 6, and a rotating shaft (not shown in the figure) for the rotation of the rotating plate 15 is arranged on the bottom plate 6. The second driving member 13 is fixed on the vehicle frame bottom plate or the vehicle frame column of the track raceway beam.

[0024] By applying a rotating force to the rotating connecting seat 14 through the second driving member 13, the rotating connecting seat 14 is driven to rotate around the rotating shaft. The second driving member 13 can drive the rotating plate 15 to rotate 90°, so that the cross beam 3 rotates 90° and is arranged parallel to the length direction of the rail, avoiding interfering with the loading and unloading of the rail. By driving the rotation of the rotating connecting seat 14 and the rotating plate 15 through the second driving member 13, the cross beam 3 is opened. An arc-shaped sliding groove is arranged on the bottom plate 6, which is convenient for guiding when the rotating plate 15 rotates and can prevent the position of the rotating plate 15 from shifting during rotation, improving the stability of the connection between the rotating plate 15 and the bottom plate 6. The second driving member 13 adopts a driving device that makes a reciprocating rotating motion, such as a rotating hydraulic cylinder, a rotating air cylinder, a rotating electric cylinder, etc. (this is the prior art and will not be elaborated here). Adopting driving devices such as rotating hydraulic cylinders, rotating air cylinders, and rotating electric cylinders is convenient for saving installation space.

[0025] A first mounting seat 16 for mounting the cross beam 3 is arranged on the rotating column 2, a second mounting seat 17 for mounting the cross beam 3 is arranged on the fixed column 1, a connecting base for bolt connection with the first mounting seat 16 is arranged at one end of the cross beam 3, and the other end is connected to the second mounting seat 17 through a placing base 18 arranged on the second mounting seat 17. Both the first mounting seat 16 and the second mounting seat 17 are connected to the vertical plate 10.

[0026] Connecting plates 20 for connecting the first mounting base 16 and the second mounting base 17 are provided on both vertical plates 10 of the fixed vertical column 1 and the rotating vertical column 2. The first mounting base 16 and the second mounting base 17 are both connected to the connecting plate 20 by bolts.

[0027] When loading or unloading the rail, the connecting base provided at one end of the cross beam 3 is connected to the rotating vertical column 2 by bolts, and the other end is placed on the placing base 18. The placing base 18 is connected to the cross beam 3 to provide support for the cross beam 3. When the cross beam 3 is opened or closed, the connection with the second mounting base 17 is more convenient. The base is set in an "L" shape. The vertical section is convenient for positioning when the cross beam 3 is connected to the fixed vertical column 1, and the horizontal section is used to provide support for the cross beam 3.

[0028] The vertical pulley 5 includes two vertical plates 10 provided on both sides of the first driving member 4 and a connecting cross plate 11 provided at the top of the vertical plate 10. A connecting pin (not shown in the figure) for connecting the vertical plate 10 is provided at the output end of the first driving member 4. The sliding assembly includes vertical pulley shafts 19 respectively provided on the two vertical plates 10 and sliding members 12 provided on the vertical pulley shafts 19 for sliding up and down in the two sliding tracks 7.

[0029] The vertical plates 10 on both sides are connected to the first driving member 4 by connecting pins. A connecting cross plate 11 is provided at the upper end of the vertical plate 10 to increase the strength of the vertical pulley 5 and ensure that the position of the vertical plate 10 does not shift during the up and down movement. Vertical pulley shafts 19 are provided on both sides of the vertical plate 10, and the sliding members 12 slide in the sliding tracks 7. The sliding tracks 7 guide and limit the sliding members 12 to prevent the vertical pulley 5 from shifting in position during the up and down movement.

[0030] On one side of both vertical plates 10 close to the first driving member 4, connecting cylinders in close contact with the first driving member 4 are provided. Connecting holes for connecting with the connecting pins are opened in the connecting cylinders. The connecting pins horizontally pass through the connecting holes on both sides and the vertical plates 10, thereby connecting with the vertical pulley 5 and driving the vertical pulley 5 to move up and down.

[0031] Among them, the connecting cross plate 11 and the vertical plate 10 are welded to improve the strength. The connecting pin is composed of a smooth round pin, washers and a pin. The smooth round pin is provided at the output end of the first driving member 4, washers are provided at both ends, and are locked by the pin. The pin adopts a split pin. The sliding member 12 adopts a bearing or a sliding wheel to facilitate the sliding of the vertical pulley 5 in the sliding track 7.

[0032] Both the first driving member 4 and the second driving member 13 are connected to a controller. The commutation of the first driving member 4 and the second driving member 13 is controlled by an electromagnetic reversing valve. The controller is electrically connected or signal-connected to the electromagnetic reversing valve, the first driving member 4, and the second driving member 13 (this is prior art and will not be elaborated here). The controller controls the opening or closing of the first driving member 4 and the second driving member 13. The controller uses a wireless remote control or a control terminal (this is prior art and will not be elaborated here).

[0033] A plurality of automatic lifting devices are arranged at intervals along the length direction of the rail on the long rail transporter. When unloading one layer of rails, the cross beam 3 is connected to the rotating column 2 and the fixed column 1. The controller controls a plurality of first driving members 4 to start simultaneously, moving multiple groups of cross beams 3 upward to lift the second layer of rails off the second-layer roller beam. At this time, the rails are supported by the cross beam 3. The second-layer roller beam is opened to perform the unloading work of the first layer of rails, avoiding the rail ends of the second layer of rails and the second-layer roller beam from intruding into the unloading movement curve of the first layer of rails, which may cause collisions between the first layer of rails and the second layer of rails or the second-layer roller beam.

[0034] After the unloading operation of the first layer of rails is completed, the controller controls the first driving member 4 to return to its original position. The piston of the first driving member 4 inside the column retracts, driving the vertical pulley 5 body to move downward, and the cross beam 3 follows the vertical pulley 5 body to descend. The second layer of rails falls on the second-layer roller beam, and then the first driving member 4 is closed.

[0035] It solves the interference problem between the rail ends of the first layer of rails and the second layer of rails or the second-layer roller beam when the long rail transport vehicle group unloads the first layer of rails alone or performs the loading and unloading operation simultaneously, improving the loading and unloading efficiency of the rails while reducing potential safety hazards.

[0036] When the long rail transport vehicle group does not perform the rail unloading operation or performs the loading and unloading operation simultaneously, the cross beam 3 is in the open state to facilitate the vehicle to load the rails. The controller controls the second driving member 13 to drive the rotating column 2 to rotate clockwise, and the cross beam 3 follows the rotating column 2 to rotate and disengages from the fixed column 1, which is the open state. At this time, the rail loading operation is performed.
