Description

Technical Field

[0001] This invention belongs to the field of dialing technology, specifically relating to a novel cantilevered electric dialing device. Background Technology

[0002] When a long rail transport vehicle collects 500m long rails, it must transfer them from the work vehicle group to the rail transport vehicle group. Once the rails arrive at the transport vehicle group, they must be laterally moved to the transport position for easy locking and transport. Typically, the rail-moving device consists of a column and bracket supporting a rail-moving beam. When moving any layer of rails laterally, the beam needs to be adjusted to a specified height before the pawls on the beam operate. One end of the rail-moving beam is a rotating shaft. When the train is unloading rails laterally at the base gantry crane, the rail-moving beam must be rotated 90° to the side of the vehicle to avoid interference.

[0003] Currently, hydraulic systems are typically used as the power source, with each rail-shifting device equipped with a hydraulic station mounted on the car floor. The rail-shifting column has two hydraulic cylinders: one adjusts the crossbeam height, and the other changes the column's rotation angle. Hydraulic motors are mounted on the crossbeam to change the position of the shifting claws for rail shifting. The addition of these hydraulic stations increases the floor space required within the car, and equipping each rail-shifting machine with its own hydraulic station increases production costs, resulting in significant initial investment. Furthermore, the hydraulic system of the rail-shifting machine suffers from substantial energy loss, approximately 30%-40%, and its transmission efficiency is lower than that of mechanical transmissions. Additionally, the system has complex piping, with most hydraulic pipes directly exposed to the air, making it sensitive to varying temperatures and dust levels, affecting rail-taking performance. Hydraulic oil leaks at pipe connections are also frequent. Regular hydraulic oil changes and pipe cleaning are necessary to prevent oil deterioration and corrosion of components such as hydraulic cylinders and motors, resulting in high maintenance costs.

[0004] Currently, the common method involves rotating a guide rail column to drive the guide rail beam, with the guide rail column and base connected by a bushing. Frequent rotation reduces stability. When unloading rails laterally from the gantry crane at the base, the guide rail beam must be manually rotated 90° to the side of the vehicle. Prolonged manual operation is susceptible to fatigue, reducing efficiency, increasing danger, and adding to personnel management costs. Summary of the Invention

[0005] This invention aims to provide a novel cantilevered electric guide rail device that features high working efficiency, low maintenance costs, and low workload. It addresses the problems of increased floor space, large initial investment, low transmission efficiency, and high maintenance costs associated with using a hydraulic system as a power source; poor stability of the guide rail column caused by rotating the guide rail column to drive the guide rail beam; and high workload and low efficiency of manually moving the guide rail beam.

[0006] Therefore, the technical solution adopted by this invention is as follows: a novel cantilevered electric guide rail device, comprising a guide rail column, a guide rail beam that can be lifted and lowered on the guide rail column, a closed bracket supporting the guide rail beam in a transverse state, and an open bracket supporting the guide rail beam in a longitudinal state. The guide rail column includes a column main frame, an electric push rod, and a sliding trolley. The telescopic end of the electric push rod is connected to the sliding trolley via a chain drive, thereby driving the sliding trolley to rise and fall along the central vertical groove of the column main frame. The guide rail beam includes a rotary assembly, a beam main frame, and a guide rail assembly. The rotary assembly is mounted on the sliding trolley and provides rotational drive for the beam main frame. The power system includes a trolley pawl that can be slidably installed at the bottom of the main beam frame and a rail drive motor that provides sliding drive for the trolley pawl. The trolley pawl and the rail drive motor are connected by a chain drive. The closed position bracket includes a closed bracket body, a limiting plate spaced vertically along the bracket body, and an anti-rotation limiting plate that can be flipped and installed on the top of the bracket body. When the rail beam is positioned at the top after the rail shifting is completed, it is locked by the flipped "L"-shaped anti-rotation limiting plate. The top of the open position bracket is provided with a tray that supports the rail beam. The tray is provided with an anti-rotation lock that can limit the rotation of the main beam frame.

[0007] As a preferred embodiment of the above solution, the telescopic end of the electric push rod is installed facing upward in the central vertical groove of the main column frame. The top of the telescopic end of the electric push rod is provided with symmetrical lifting sprockets and a lifting chain. One end of the lifting chain is fixed to the main column frame, and the other end passes around the upper lifting sprocket and connects to the sliding trolley. When the telescopic end of the electric push rod extends or retracts, the sliding trolley is driven to rise or fall through the lifting chain. The chain drive results in low maintenance costs and convenient and quick automated operation.

[0008] Further preferably, the main support frame includes left and right mirror-symmetrical column channel steel, a bottom plate at the bottom, and a top plate at the top. An inverted "V" shaped angle steel is welded in the center of the column channel steel to form a sliding groove for the sliding trolley to roll. The V-shaped track is made of angle steel welded inside, so that the device is subjected to more even force during the track shifting process. The unique track design is combined with the characteristics of the sliding trolley rollers. A new structure relying on V-shaped wheels is used to connect the rotary component and the track shifting column. The design structure is ingenious.

[0009] The main support frame is equipped with an electric push rod mounting seat, a chain mounting seat, and a vehicle body connecting seat. The electric push rod mounting seat is provided with a ring frame for the electric push rod to ensure that the electric push rod is installed vertically and that the telescopic end can extend and retract vertically.

[0010] The chain mounting base is provided with two bolt mounting bases spaced apart on the left and right, and is equipped with chain mounting bolts accordingly. The car body connecting base is arranged vertically at intervals to reinforce the rail column and the side wall of the car body, making the structure stable. An electrical control box is installed on the top of the main column frame away from the rail beam to avoid the electrical control box taking up too much space.

[0011] A further preferred embodiment is that the bottom end of the electric push rod is bolted to a fixing plate, and the fixing plate is welded to the base plate, so that the fixed end of the electric push rod is securely installed.

[0012] The telescopic end of the electric push rod is bolted with a sprocket mounting post. The left and right symmetrical lifting sprockets are connected by a sprocket shaft. The sprocket mounting post and the sprocket shaft are fixed with bolts. The structure is interlocked and firmly installed.

[0013] More preferably, the sliding trolley includes a rotary mounting plate, roller mounting plates spaced apart on the left and right, and rollers spaced apart on the roller mounting plates. The concave part in the center of the roller matches the inverted "V" shaped angle steel, so that it can roll up and down along the inverted "V" shaped angle steel, which is a clever design.

[0014] The top of the roller mounting plate is provided with a pin hole for connection with the lifting chain, and the structure is reasonably designed.

[0015] More preferably, the rotary assembly includes a rotary mounting base mounted on a sliding trolley, a rotary drive motor mounted on the rotary mounting base, and a rotary sleeve mounted on the rotary mounting base and connected to the rotary drive motor shaft at one end of the main beam frame. The rotary sleeve is connected to the rotary mounting base bearing. When the rotary drive motor starts, it drives the main beam frame to rotate through the rotary sleeve, and the structure is interlocked.

[0016] More preferably, the rotary mounting base includes a connecting vertical plate, an "L"-shaped rotary base plate, and a rotary horizontal top plate threaded onto the top of the "L"-shaped rotary base plate. The connecting vertical plate vertically connects the rotary horizontal top plate and the horizontal end of the "L"-shaped rotary base plate, thereby forming a frame structure for mounting the rotary sleeve. The frame corners are all supported, making the structure stable.

[0017] The vertical end of the "L"-shaped rotating base plate is bolted to the sliding trolley, ensuring a secure installation.

[0018] The rotating horizontal top plate is provided with threaded holes for installing the rotating drive motor and has through holes for the rotating shaft of the rotating drive motor to pass through, which is a reasonable structural design.

[0019] The corners of the connecting upright plate and the "L"-shaped rotating base plate facing the main beam frame are rounded, and the contact surfaces with the end plates of the main beam frame are threaded with isolation buffer pads to avoid direct collision and interference between the main beam frame and the rotating components when the main beam frame rotates. The structural design is reasonable.

[0020] The top of the vertical end of the "L"-shaped rotary base plate is provided with a top plate mounting plate that is threadedly connected to the rotary horizontal top plate. The top of the rotary horizontal top plate is provided with a mounting block that is bolted to the sliding trolley. Although the rotary horizontal top plate is threadedly installed on the "L"-shaped rotary base plate, the rotary horizontal top plate and the "L"-shaped rotary base plate are still threadedly connected to the sliding trolley respectively to ensure structural stability.

[0021] Preferably, the bottom of the main beam frame is provided with a guide rail groove, and a guide rail sprocket and a guide rail chain are installed in the guide rail groove. The guide rail sprocket is located at both ends of the guide rail groove, and the guide rail chain is installed in a ring on the guide rail sprocket. The top of the trolley pawl is provided with a roller that moves along the guide rail groove, and the front and rear ends of the top are connected to the guide rail chain. The other end of the main beam frame away from the rotary mounting seat is provided with a drive box and a guide rail drive sprocket one, a guide rail drive chain, and a guide rail drive sprocket two, all of which are installed in the drive box. The guide rail drive sprocket one is connected to the shaft of the guide rail drive motor, and the guide rail drive sprocket two is coaxially connected to the guide rail sprocket. The guide rail drive chain connects the guide rail drive sprocket one and the guide rail drive sprocket two. When the guide rail drive motor starts, the guide rail drive chain synchronously drives the guide rail drive sprocket two and the guide rail sprocket to rotate, thereby driving the trolley pawl to move along the guide rail groove. The structure is interlocked.

[0022] Preferably, the limiting plate is rotatably mounted on the bracket body and has a horizontal stop below it, so that the limiting plate cannot be rotated downward from the horizontal state. The anti-rotation limiting plate has an overall "L" shaped structure. When rotated to the horizontal state, it combines with the limiting plate in the highest horizontal state to form a frame that holds the guide beam, thereby avoiding the risk of the guide beam rotating during transportation after the guide is completed.

[0023] The bracket body has a triangular reinforcing plate at the bottom that contacts the vehicle floor, making the structure stable.

[0024] Preferably, the side wall of the main beam near the openable bracket is provided with an "L"-shaped bracket, which, together with the side wall of the main beam, forms a "U"-shaped groove. The tray is generally "L"-shaped, and the horizontal edge is provided with a downward and outward inclined bending structure to avoid serious collisions when the beam rotates. The anti-rotation lock is rotatably installed on the vertical end of the tray. The anti-rotation lock is generally "L"-shaped and can rotate to hook the "U"-shaped groove formed by the "L"-shaped bracket and the side wall of the main beam. The structure is interlocked and reasonably designed.

[0025] The beneficial effects of this invention are:

[0026] (1) Compared with the use of hydraulic system as power source, this solution uses electric push rod, rail drive motor, etc. Electric push rod is used as power source for lifting and lowering rail beam. By changing the extension and retraction of electric push rod, the height of rail beam can be adjusted in time through chain drive. The motor drive equipment is simple and reliable, and easy to maintain and repair. Compared with hydraulic drive, the energy utilization rate is higher. Remote control can realize the functions of automatic rail shifting and automatic lifting and lowering of rail beam, which greatly reduces the workload and reduces the workload.

[0027] (2) Compared with the method of rotating the rail column to drive the rail beam to rotate, the rail column of this solution is fixedly connected to the car body and the rail beam is driven to rotate by the slewing component. The rail column is more stable and ensures the safe operation of the equipment.

[0028] (3) Compared with manual handling of the rail beam, this solution achieves automatic lifting and rotation of the rail beam within a certain range during operation or transportation by using a rotary component and an electric push rod. This eliminates the need for manual assistance in handling the rotating rail beam, significantly reducing the risk to workers and improving work efficiency. The design includes open and closed brackets to ensure that the rail beam is in a non-interference position during rail loading, unloading, collection, and transportation, thereby improving the safety of operators and the service life of the device.

[0029] In summary, the present invention has the advantages of simple and reliable motor-driven equipment, automated operation, strong stability of the guide rail column, and improved operation efficiency. Attached Figure Description

[0055] The telescopic end of the electric push rod 12 is bolted with a sprocket mounting post 123, and the left and right symmetrical lifting sprockets 121 are connected by a sprocket shaft.

[0058] The concave part of the roller 133 in the center matches the inverted "V" shaped angle steel 112, so that it can roll up and down along the inverted "V" shaped angle steel 112.

[0059] The top of the roller mounting plate 132 is provided with a pin hole for connection with the lifting chain 14.

[0060] The guide rail crossbeam 2 consists of a rotary assembly 21, a crossbeam main frame 22, and a guide rail assembly 23.

[0063] One end of the main beam 22 is provided with a rotary sleeve 221 that is mounted on a rotary mounting base 211 and connected to the shaft of the rotary drive motor 212.

[0064] The slewing sleeve 221 is connected to the slewing mounting base 211 bearing.

[0071] The top of the vertical end of the “L”-shaped rotary base plate 211a is provided with a top plate mounting plate 211e that is threadedly connected to the rotary horizontal top plate 211b.

[0072] The top of the rotating horizontal top plate 211b is provided with a mounting block 211f that is bolted to the sliding trolley 13.

[0073] The bottom of the main beam frame 22 is equipped with a guide rail groove.

[0074] The guide rail sprocket 222 and guide rail chain 223 are installed inside the guide rail groove.

[0075] The sprocket 222 is located at both ends of the sprocket groove.

[0076] The guide chain 223 is mounted in a ring shape on the guide sprocket 222.

[0077] The top of the trolley pawl 231 is provided with a roller that moves along the slide rail groove, and the front and rear ends of the top are connected to the slide rail chain 223.

[0078] The other end of the main beam frame 22 away from the slewing mounting base 211 is equipped with a drive box 226 and a guide rail drive sprocket 1 227, a guide rail drive chain 224, and a guide rail drive sprocket 225, all of which are installed in the drive box 226.

[0080] The dial drive chain 224 connects to dial drive sprocket one 227 and dial drive sprocket two 225.

[0081] The guide rail assembly 23 consists of a trolley pawl 231 that can be translatably mounted at the bottom of the main beam frame 22 and a guide rail drive motor 232 that provides translational drive for the trolley pawl 231.

[0082] The trolley pawl 231 and the guide rail drive motor 232 are connected by chain drive.

[0083] When the dial drive motor 232 starts, the dial drive chain 224 synchronously drives the dial drive sprocket 225 and the dial sprocket 222 to rotate, thereby driving the trolley pawl 231 to move along the dial slide groove.

[0084] The closed bracket 3 consists of a closed bracket body 31, a limiting plate 32 spaced vertically along the bracket body 31, and an anti-rotation limiting plate 33 that can be flipped and installed on the top of the bracket body 31.

[0085] When the guide beam 2 is positioned at the top level after guide rail adjustment, it is locked in place by the flipped-over "L"-shaped anti-rotation limit plate 33.

[0086] The limiting plate 32 can be flipped and installed on the bracket body 31, and a horizontal stop 321 is provided below it, so that the limiting plate 32 cannot be flipped downward from the horizontal state.

[0087] The anti-rotation limiting plate 33 has an overall "L" shape structure. When flipped to the horizontal state, it combines with the limiting support plate 32 of the highest horizontal state to form a frame that holds the guide rail beam 2.

[0088] The bottom of the bracket body 31 is provided with a triangular reinforcing plate that contacts the vehicle floor.

[0089] The top of the openable bracket 4 is provided with a tray 41 that supports the dial rail beam 2.

[0090] The tray 41 is equipped with an anti-rotation lock 411 that can limit the rotation of the main beam 22.

[0091] The main beam 22 has an "L"-shaped bracket 228 on its side wall near the open position bracket 4, which forms a "U"-shaped groove with the side wall of the main beam 22.

[0092] The tray 41 is L-shaped, and the horizontal edge has a downward and outward bending structure.

[0093] The anti-rotation lock 411 can be rotatably installed on the vertical end of the tray 41.

[0094] The anti-rotation lock 411 has an overall "L" shaped structure. When the main beam 22 is in the open position, the anti-rotation lock 411 can rotate to hook the "U" shaped groove formed by the "L" shaped bracket 228 and the side wall of the main beam 22.

[0095] The specific operating steps are as follows: Before the rail shifting operation, control the rail shifting beam 2 to rise above the height of the retrieved rails. After the rails are retrieved into position, lower the rail shifting beam 2 to the corresponding baffle of the closed position bracket 3, and control the pulley claw 231 to shift the two rails to the predetermined positions. If jamming occurs during the shifting process, control the rail shifting beam 2 to rise, using the annular groove at the bottom of the pulley claw 231 to hook the rails and lift them to a certain height before continuing the shifting. After the shifting is completed, raise the rail shifting beam 2 to the next level height to prepare for shifting the next pair of rails.

[0096] When the gantry crane at the base is unloading rails laterally, the guide beam 2 is stopped. The guide beam 2 is raised to the highest point, at which point the end of the guide beam 2 is higher than the upper end of the closed position bracket 3. The rotary drive motor 212 is used to rotate the guide beam 2 by 90°. The guide beam 2 can be prevented from descending due to the self-locking effect of the threaded electric push rod 12.

[0097] The rail shifting beam is parked during rail loading at the base and rail unloading on the line. During rail loading at the base and rail unloading on the line, the rail shifting beam 2 does not participate in the operation. The rail shifting beam 2 can be lowered to its lowest point, and the pulley claw 231 is aligned with the claw mounting hole on the steel floor. The pulley claw 231 is inserted into the claw mounting hole. At this time, the upper part of the rail shifting beam 2 is lower than the bottom of one layer of rail, and no interference occurs.
