[0002] The car transfer platform is a steering device for transferring empty cars from heavy car lines to empty car lines, which is suitable for the emptying line of the turn-back dumper and can be arranged indoors or outdoors.

[0003] The above-mentioned technology uses a motor to drive the gear to pull the car compartment, but in the actual process, the impact force generated when the car compartment enters the car transfer platform from the heavy car line is too large, which causes the gear and the connected motor to be easily damaged by impact, resulting in a high failure rate of the car transfer platform during use. UTILITY MODEL CONTENTS

[0007] Preferably, the rebound assembly comprises a plurality of tension springs and a stabilizing plate, the stabilizing plate is installed at the end of the lower guide rail, one end of the tension spring is connected to the stabilizing plate, and the other end of the tension spring is connected to the end of the limiting plate away from the traction rope.

[0008] Preferably, the number of the tension springs is even, and the tension springs are uniformly distributed with the center of the traction rope as the symmetry line.

[0009] Preferably, the number of the walking wheels is greater than or equal to four, and the inner side of the walking wheels is provided with an outwardly extending guide part.

[0010] Preferably, the middle part of the plate body of the blocking plate is provided with a buffer assembly, and the blocking plate is connected with a contact plate through the buffer assembly.

[0011] Preferably, the buffer assembly comprises a mounting cylinder, a connecting rod and a compression spring, the mounting cylinder is mounted in the middle part of the blocking plate, one end of the connecting rod is slidably arranged in the mounting cylinder, the other end of the connecting rod is located outside the mounting cylinder and connected with the lower end of the contact plate, and the compression spring is located between the mounting cylinder and the connecting rod.

[0012] Preferably, both ends of the mounting cylinder are provided with pressure relief openings, and the pressure relief openings are provided with filter plugs.

[0013] The car transfer platform of the tumbler provided by the utility model has the beneficial effects that:

[0014] 1: In the utility model, when the carriages flow out from the heavy car line after completing unloading, the carriages directly pass through the upper guide rails to the upper surface of the mounting plate, and finally stably stop at the tail end of the upper guide rail on the upper surface of the mounting plate after kinetic energy reduction by the buffer assembly. In this process, the large impact force generated during the stopping of the carriages is not directly transmitted to the telescopic member because the telescopic member output end and the limiting plate are connected by a traction rope, so that the impact on the telescopic member is greatly reduced, thereby effectively avoiding the damage of the telescopic member due to excessive impact, and solving the defect that the kinetic energy generated by the impact during the stopping of the carriages cannot be reduced and is transmitted to the electrical devices, causing the motor and gear to be easily damaged.

[0015] 2: In the utility model, the setting of the buffer assembly causes the resistance generated by the compression spring to counteract the kinetic energy generated when the carriages flow into the mounting plate, thereby gradually reducing the kinetic energy when the carriages move, until the contact plate moves to the tail end of the upper guide rail, at which time the contact plate cannot continue to move backward, and the rebound force of the compression spring cannot push the carriages to move forward, that is, the carriages stop at this position and wait to be transported to the empty car line. Therefore, by the setting of the buffer assembly, when the carriages finally stop stably, the kinetic energy carried by the carriages is resisted and reduced by the compression spring, thereby reducing the impact on the mounting plate when the carriages stop on the upper surface of the mounting plate, thereby reducing the impact intensity on the car transfer platform, that is, the risk of damage of the car transfer platform due to excessive impact is reduced to a certain extent.

[0025] Embodiment 2

[0026] Referring to Figures 1-5 , in the case that the other parts are the same as those in embodiment 1, the difference between the embodiment 1 and the embodiment 2 is that:

[0027] The rebound assembly comprises a plurality of tension springs 10 and a stabilizing plate 11 mounted at the end of the lower guide rail 3, one end of the tension spring 10 is connected with the stabilizing plate 11, the other end of the tension spring 10 is connected with the limiting plate 8 away from one end of the traction rope 5, the number of the tension spring 10 is even, the tension spring 10 is evenly distributed with the center of the traction rope 5 as the symmetry line, the number of the walking wheel 2 is greater than or equal to four, the inner side of the walking wheel 2 is provided with an outwardly extending guide portion, the setting of the rebound assembly makes the installation plate 1 automatically move from the empty car line to the heavy car line under the pulling of the tension spring 10 when the installation plate 1 is reset after the carriage is transported to the empty car line, and in this process, the rebound speed of the installation plate 1 can be adjusted by controlling the extension speed of the output end of the telescopic member 4, that is, when the limiting plate 8 on the lower surface of the installation plate 1 is about to contact the positioning plate 9, the extension speed of the output end of the telescopic member 4 is reduced, at this time, the telescopic member 4 controls the installation plate 1 to slowly contact the positioning plate 9 through the traction rope 5, thereby avoiding the phenomenon that the installation plate 1 is violently impacted on the positioning plate 9 by the tension spring 10, thereby avoiding the damage to the equipment caused by the violent impact at this time, the setting of the guide portion of the walking wheel 2 makes the contact between the walking wheel 2 and the lower guide rail 3 more stable.

[0028] The middle part of the plate body of the blocking plate 7 is provided with a buffer assembly, the blocking plate 7 is connected with a contact plate 12 through the buffer assembly, the buffer assembly comprises a mounting cylinder 13, a connecting rod 14 and a compression spring 15, the mounting cylinder 13 is mounted at the middle part of the blocking plate 7, one end of the connecting rod 14 is slidably arranged in the mounting cylinder 13, the other end of the connecting rod 14 is located outside the mounting cylinder 13 and connected with the lower end of the contact plate 12, the compression spring 15 is located between the mounting cylinder 13 and the connecting rod 14, both ends of the mounting cylinder 13 are provided with pressure relief ports, filter plugs 16 are arranged in the pressure relief ports, through the setting of the buffer assembly and the contact plate 12, the contact plate 12 is pushed away from the blocking plate 7 by the buffer assembly before it contacts with the external carriage, when the carriage flows out from the heavy car line and enters the upper guide rail 6 of the installation plate 1, the lower side of the end part of the carriage gradually approaches the upper end of the contact plate 12 and finally pushes the contact plate 12 to move backward, when the contact plate 12 moves, the compression spring 15 in the mounting cylinder 13 is compressed through the connecting rod 14, thereby the resistance generated by the compression spring 15 being continuously compressed counteracts the kinetic energy generated when the carriage flows into the installation plate 1, thereby gradually reducing the kinetic energy when the carriage moves, until the contact plate 12 is moved to the tail end of the upper guide rail 6, at this time, the contact plate 12 cannot continue to move backward, and the rebound force of the compression spring 15 also cannot push the carriage to move forward, that is, the carriage stops here and waits to be transported to the empty car line, thereby through the setting of the buffer assembly, when the carriage is finally stably stopped, the kinetic energy carried by the carriage is resisted and reduced by the compression spring 15, thereby reducing the impact on the installation plate 1 when the carriage stops on the upper surface of the installation plate 1, thereby reducing the impact force on the migration platform, that is, to a certain extent, the risk of damage to the migration platform due to the excessive impact is reduced.

[0029] Principle and advantages: in the use process, when the mounting plate 1 is parked at the positioning plate 9 through the limiting plate 8 under the action of the tension spring 9, the corresponding place is the heavy car line of the outside, and the one end of the lower guide rail 3 close to the telescopic piece 4 corresponds to the empty car line of the outside, and then when the carriage flows out from the heavy car line after completing unloading, the carriage directly enters the upper surface of the mounting plate 1 through the upper guide rail 6, and finally stably parks at the tail end of the upper guide rail 6 on the upper surface of the mounting plate 1 after kinetic energy reduction by the buffer assembly, and in the process, the telescopic piece 4 is not directly transmitted to the telescopic piece 4 due to the soft connection between the output end of the telescopic piece 4 and the limiting plate 8 through the traction rope 5, so that the impact on the telescopic piece 4 is greatly reduced, thereby effectively avoiding the phenomenon that the telescopic piece 4 is damaged due to excessive impact.

[0030] Further, in the above process, when the carriage is parked stably, the output end of the telescopic piece 4 pulls the mounting plate 1 to move to the other end through the traction rope 5, that is, the mounting plate 1 moves to the empty car line of the outside, at this time, the pushing device of the empty car line of the outside gradually approaches the tail end of the carriage, and finally pushes the carriage to move from the mounting plate 1 to the empty car line of the outside, and finally the carriage is moved into the empty car line, at this time, the carriage moving process is completed, and then the mounting plate 1 is reset under the driving of the rebound assembly for the next carriage moving process.

[0031] It should be further pointed out that the setting of the rebound assembly makes the mounting plate 1 move from the empty car line to the heavy car line under the pulling of the tension spring 10 when the mounting plate 1 is reset after transporting the carriage to the empty car line, and in the process, the rebound speed of the mounting plate 1 can be adjusted by controlling the extension speed of the output end of the telescopic piece 4, that is, when the limiting plate 8 on the lower surface of the mounting plate 1 is about to contact the positioning plate 9, the output end of the telescopic piece 4 reduces the moving speed, at this time, the telescopic piece 4 controls the mounting plate 1 to slowly contact the positioning plate 9 through the traction rope 5, thereby avoiding the phenomenon that the mounting plate 1 is violently impacted by the tension spring 10, thereby avoiding damage to the equipment caused by the violent impact at this time, and the setting of the guide part of the walking wheel 2 makes the contact between the walking wheel 2 and the lower guide rail 3 more stable.

[0032] The buffer assembly pushes the contact plate 12 away from the blocking plate 7, and when the carriages flow out from the heavy vehicle line to the upper guide rail 6 of the installation plate 1, the lower side of the end of the carriages gradually approaches the upper end of the contact plate 12 and finally pushes the contact plate 12 to move backward, and when the contact plate 12 moves, the compression spring 15 inside the installation cylinder 13 is compressed through the connecting rod 14, so that as the compression spring 15 is continuously compressed, the resistance generated by the compression spring 15 collides with the kinetic energy generated when the carriages flow into the installation plate 1, thereby gradually reducing the kinetic energy when the carriages move, until the contact plate 12 is moved to the tail end of the upper guide rail 6, at this time the contact plate 12 cannot continue to move backward, and the rebound force of the compression spring 15 cannot push the carriages to move forward, that is, the carriages stop at this place and wait to be transported to the empty vehicle line, so that through the setting of the buffer assembly, when the carriages finally stop stably, the kinetic energy carried by the carriages is resisted and reduced by the compression spring 15, thereby reducing the impact on the installation plate 1 when the carriages stop on the upper surface of the installation plate 1, thereby reducing the impact force on the car transfer platform, that is, to a certain extent, the risk of damage to the car transfer platform due to excessive impact is reduced.

[0033] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
