Description

Technical Field

[0001] The present invention relates to the technical field related to rail collection and unloading, and in particular to an automatic rail lifting device. Background Art

[0002] When a long rail transport train unloads a single layer of rails, or simultaneously collects and unloads rails (unloading a new rail on one layer while collecting old rails on the second layer), the first layer of rails rises along a specific transition curve, interfering with the ends of the second layer of rails or the second layer of track beams. Due to the high kinetic energy of the rails during unloading, the impact and friction can severely damage the rail surface and the track beam steel structure, causing economic losses and posing certain safety risks.

[0003] The existing long rail transport vehicle group adopts the method of unloading rails layer by layer when unloading rails, that is, unloading the second layer of rails first, and then opening the second layer of rolling beams to unload the next layer of rails.

[0004] It is not possible to unload one layer of rails separately or collect and unload rails at the same time. When storing old rails on the second layer, the second layer of rails must be unloaded first before the new layer of rails can be unloaded. After unloading the rails, the old rails on the ground need to be collected, which greatly increases the time and labor costs. Summary of the Invention

[0005] The present invention aims to provide an automatic rail lifting device to solve the problem of interference between the rail ends of the first and second layers of rails or the second layer of rolling stock when a long rail transport vehicle group unloads one layer of rails alone or performs rail collection and unloading operations simultaneously, thereby improving the efficiency of loading and unloading rails and reducing safety hazards.

[0006] To this end, the technical solution adopted by the present invention is: an automatic rail lifting device, comprising two columns relatively arranged on the left and right sides of the frame, the columns comprising a fixed column and a rotating column, a crossbeam for lifting the rails is arranged between the fixed column and the rotating column, a lifting structure for lifting the crossbeam is arranged in each of the columns, and a rotating structure for rotating the rotating column is arranged on the rotating column; the lifting structure comprises a first driving member, a vertical pulley arranged at the output end of the first driving member, and a sliding assembly arranged on the vertical pulley and sliding up and down in the column.

[0007] As a preferred embodiment of the above scheme, the column includes a base plate, two sliding rails arranged on the base plate relative to each other in the front and rear directions, and a top plate arranged on the top of the sliding rails. A fixing seat for fixing the first driving member is provided on the base plate, and the fixing seat is arranged between the two sliding rails.

[0008] Further preferably, the vertical pulley includes two vertical plates arranged on both sides of the first driving member and a connecting horizontal plate arranged at the top of the vertical plates, the output end of the first driving member is provided with a connecting pin for connecting the vertical plates, and the sliding assembly includes vertical pulley axles respectively arranged on the two vertical plates and sliding members arranged on the vertical pulley axles for sliding up and down in two sliding rails.

[0009] Further preferably, the rotating structure includes a second driving member arranged below the rotating column, a rotating connecting seat connected to the output end of the second driving member, and a rotating plate arranged on the rotating connecting seat, the rotating plate is arranged on the base plate, and the base plate is provided with a rotating shaft for rotating the rotating plate.

[0010] Further preferably, a first mounting seat for mounting a crossbeam is provided on the rotating column, a second mounting seat for mounting a crossbeam is provided on the fixed column, one end of the crossbeam is provided with a connecting base for being bolted to the first mounting seat, and the other end is connected to the second mounting seat through a placement base provided on the second mounting seat, and the first mounting seat and the second mounting seat are both connected to the vertical plate.

[0011] The beneficial effects of the present invention are as follows: the second layer of rails can be lifted by the lifting structure, so that the second layer of roller beams can be opened, thereby avoiding the collision caused by the second layer of rail ends and the second layer of roller beams invading the first layer of rails during rail unloading movement curve. One layer of rails can be unloaded separately on the long rail transport vehicle, or rail collection and unloading operations can be performed simultaneously. When storing old rails on the second layer, new rails on the first layer can be unloaded without unloading the second layer of rails, thus saving time and labor costs, improving the efficiency of loading and unloading rails, and reducing safety hazards.

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

[0018] like Figure 1-5 As shown, the automatic rail lifting device includes two columns relatively arranged on the left and right sides of the frame, the columns include a base plate 6, two sliding rails 7 relatively arranged on the base plate 6 in the front and rear directions, and a top plate 8 arranged at the top of the sliding rails 7. A fixing seat 9 for fixing the first driving member 4 is provided on the base plate 6, and the fixing seat 9 is arranged between the two sliding rails 7.

[0019] The base plate 6 is bolted to the frame of the long rail transport vehicle, facilitating disassembly and maintenance of the columns. Multiple triangular reinforcement ribs are installed between the base plate 6 and the sliding rails 7 to enhance the strength of the sliding rails 7. A fixing base 9, positioned between the two sliding rails 7, secures the first drive member 4, facilitating the sliding of the vertical trolley 5 mounted on the first drive member 4 within the sliding rails 7. The sliding rails 7 on both sides ensure stability as the vertical trolley 5 slides up and down. The first drive member 4 utilizes a linear reciprocating drive device, such as a pneumatic cylinder, electric cylinder, or hydraulic cylinder (this is prior art and will not be further described here).

[0020] Sliding track 7 utilizes portal channel steel, a special type of channel steel commonly used in forklift masts—the components on forklifts that secure cargo. This channel steel has a C-shaped cross-section and is therefore also called a C-type forklift portal channel. It offers high strength and rigidity, ensuring stability in a variety of operating environments. Furthermore, its design incorporates lightweighting, effectively reducing overall vehicle weight and energy consumption. The portal channel steel boasts a long service life, reducing the cost of frequent replacement and maintenance. Furthermore, the design incorporates maintenance requirements, facilitating routine inspections and maintenance.

[0021] The columns include a fixed column 1 and a rotating column 2. A crossbeam 3 for lifting the rail is provided between the fixed column 1 and the rotating column 2. A lifting structure for lifting the crossbeam 3 is provided in each column. The lifting structure includes a first driving member 4, a vertical pulley 5 provided at the output end of the first driving member 4, and a sliding assembly provided on the vertical pulley 5 and sliding up and down in the column.

[0022] A fixed column 1 and a rotating column 2 are set, and a crossbeam 3 is set between the fixed column 1 and the rotating column 2. The rotation of the rotating column 2 drives the crossbeam 3 to separate from the fixed column 1, thereby opening the crossbeam 3. At this time, it is convenient for the train set to load the rails. When unloading the rails, the crossbeam 3 is in a closed state, and the crossbeam 3 is driven to move upward by the lifting structure. The crossbeam 3 drives the upper rails to leave the roller beam. At this time, the upper roller beam is opened to dismantle the lower rails. A vertical pulley 5 and a sliding assembly are set, and the up and down movement of the crossbeam 3 is smoother, which improves stability. The crossbeam 3 is made of H-shaped steel, and the material is Q345B. H-shaped steel has a large load-bearing capacity and good stability. Q345B is a low-alloy high-strength steel with high strength and good plasticity and weldability. It is suitable for heavy building structures and important load-bearing components.

[0023] The rotating column 2 is provided with a rotating structure for rotating the column 2. The rotating structure includes a second driving member 13 disposed below the rotating column 2, a rotating connection base 14 connected to the output end of the second driving member 13, and a rotating plate 15 disposed on the rotating connection base 14. The rotating plate 15 is mounted on the base plate 6, and the base plate 6 is provided with a rotating shaft (not shown) for rotating the rotating plate 15. The second driving member 13 is fixed to the frame base plate or the track roller beam frame column.

[0024] The second drive member 13 applies a rotational force to the rotating connector 14, thereby driving the rotating connector 14 to rotate about the rotation axis. The second drive member 13 can drive the rotating plate 15 to rotate 90°, thereby causing the crossbeam 3 to rotate 90° and be arranged parallel to the length direction of the rail to avoid interfering with the loading and unloading of the rail. The second drive member 13 drives the rotating connector 14 and the rotating plate 15 to rotate, thereby opening the crossbeam 3. An arc-shaped sliding groove is provided on the base plate 6 to facilitate the guidance of the rotating plate 15 during rotation and to prevent the rotating plate 15 from shifting during rotation, thereby improving the stability of the connection between the rotating plate 15 and the base plate 6. The second drive member 13 uses a drive device that performs reciprocating rotation, such as a rotating hydraulic cylinder, a rotating cylinder, a rotating electric cylinder, etc. (this is existing technology and will not be repeated here). The use of a driving device such as a rotating hydraulic cylinder, a rotating cylinder, and a rotating electric cylinder saves installation space.

[0025] A first mounting seat 16 for mounting the crossbeam 3 is provided on the rotating column 2, and a second mounting seat 17 for mounting the crossbeam 3 is provided on the fixed column 1. One end of the crossbeam 3 is provided with a connecting base for being bolted to the first mounting seat 16, and the other end is connected to the second mounting seat 17 through a placement base 18 provided 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] A connecting plate 20 for connecting the first mounting seat 16 and the second mounting seat 17 is provided on the two vertical plates 10 of the fixed column 1 and the rotating column 2. The first mounting seat 16 and the second mounting seat 17 are connected to the connecting plate 20 by bolts.

[0027] When loading or removing rails, the connection base provided at one end of the crossbeam 3 is connected to the rotating column 2 by bolts, and the other end is placed on the placement base 18, which is connected to the crossbeam 3 to provide support for the crossbeam 3. When the crossbeam 3 is opened or closed, the connection with the second mounting base 17 is more convenient. The base is set in an "L" shape, with the vertical section facilitating the positioning of the crossbeam 3 when connected to the fixed column 1, and the horizontal section providing support for the crossbeam 3.

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

[0029] The vertical plates 10 on both sides are connected to the first driving member 4 through connecting pins. A connecting cross plate 11 is set 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 will not shift during the up and down movement. Vertical pulley axles 19 are set on both sides of the vertical plate 10, and slide in the sliding track 7 through the sliding member 12. The sliding member 12 is guided and limited by the sliding track 7 to prevent the vertical pulley 5 from shifting when moving up and down.

[0030] The two vertical plates 10 are each provided with a connecting tube that is in close contact with the first driving member 4 on one side. A connecting hole for connecting with a connecting pin is opened in the connecting tube. The connecting pin passes horizontally through the connecting holes on both sides and the vertical plates 10, thereby connecting with the vertical pulley 5 to drive the vertical pulley 5 to move up and down.

[0031] The connecting crossbar 11 and vertical plate 10 are welded to enhance strength. The connecting pin consists of a plain round pin, a washer, and a pin. The plain round pin is located at the output end of the first drive member 4, with washers at both ends and locked by a cotter pin. The sliding member 12 is a bearing or sliding wheel to facilitate the sliding of the vertical trolley 5 within the sliding track 7.

[0032] The first and second drive members 4 and 13 are both connected to a controller. The switching of the first and second drive members 4 and 13 is controlled by an electromagnetic reversing valve. The controller is electrically or signal-connected to the electromagnetic reversing valve, the first and second drive members 4 and 13 (this is prior art and will not be described in detail here). The controller controls the opening and closing of the first and second drive members 4 and 13. The controller is a wireless remote control or a control terminal (this is prior art and will not be described in detail here).

[0033] A plurality of automatic lifting devices are used and arranged at intervals on the long rail transport vehicle along the length direction of the rails. When unloading the first layer of rails, the crossbeam 3 is connected to the rotating column 2 and the fixed column 1. The controller controls the plurality of first driving members 4 to start simultaneously, and moves the plurality of crossbeams 3 upward to bring the second layer of rails away from the second layer of roller beams. At this time, the rails are supported by the crossbeam 3, and the second layer of roller beams are opened to unload the first layer of rails, so as to avoid the rail ends of the second layer of rails and the second layer of roller beams invading the unloading motion curve of the first layer of rails during the unloading process of the first layer of rails, resulting in a collision between the first layer of rails and the second layer of roller beams.

[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, and drives the vertical pulley 5 to move downward, the crossbeam 3 follows the vertical pulley 5 to descend, the second layer of rails falls on the second layer of raceway beam, and then the first driving member 4 is closed.

[0035] The invention solves the problem of interference between the first layer rail and the second layer rail end or the second layer rolling beam when the long rail transport train unloads one layer of rails separately or collects and unloads rails at the same time, thereby improving the efficiency of loading and unloading rails while reducing safety hazards.

[0036] When the long rail transport train is not unloading rails or is simultaneously loading and unloading rails, the crossbeam 3 is in the open state to facilitate rail loading. The controller controls the second driving member 13 to drive the rotating column 2 to rotate clockwise, and the crossbeam 3 rotates with the rotating column 2 and separates from the fixed column 1, which is the open state, at which time rail loading can be carried out.

[0037] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
