Abstract
Description
Technical Field
[0001] This utility model belongs to the field of escalator technology, specifically relating to an auxiliary platform for loading and unloading rails on long rail transport trains. Background Technology
[0002] The 32 crane units at the Yucheng base have been completed and put into production. Currently, when the long-rail vehicles are used to lift steel rails, the space for personnel to hide is narrow. When lifting the westernmost rail, personnel need to hold onto the long-rail vehicle for support while simultaneously controlling the crane unit to move the rail horizontally. This process is complex, inefficient, and carries a risk of falls and injuries. The area near the crane units at the Yucheng base has four or five tracks, making it unsuitable for installing long-rail ladders or platforms. Therefore, a safe and stable hiding space is crucial for ensuring the safety, efficiency, and traffic safety of lifting operations.
[0003] However, the implementation of the relevant technologies revealed the following problems with the above-mentioned solutions: existing escalators have low operating efficiency, pose a risk of falls and injuries, and some lines do not meet the conditions for installing long-rail escalators or platforms. Furthermore, installing a rotating platform requires workers to stand on it, placing significant tensile stress on the bearings, which can easily deform and damage the bearings over time, reducing their lifespan. Therefore, this paper proposes an auxiliary platform for loading and unloading rails on long-rail transport trains to solve these problems. Utility Model Content
[0004] This invention proposes an auxiliary platform for loading and unloading rails on long rail transport trains, which solves the problem of bearings being subjected to great tensile force when using rotating platforms on escalators in related technologies.
[0005] The technical solution of this utility model is as follows: an auxiliary platform for loading and unloading rails on long rail transport trains, comprising: a support platform and a ladder for climbing;
[0006] The top of the escalator is equipped with a bearing, and a rotating platform is rotatably mounted on the top of the escalator via the bearing.
[0007] A support plate is fixedly installed inside the support platform. A fixed shaft is rotatably installed inside the support plate. A first lead screw is fixedly installed outside the fixed shaft. A positive and negative threaded sleeve is installed on the external thread of the first lead screw. A second lead screw is installed on the internal thread of the positive and negative threaded sleeve. A support shaft is fixedly installed at one end of the second lead screw.
[0008] A limiting component is fixedly installed at the bottom of the rotating platform, and the limiting component has a groove inside.
[0009] Preferably, a rotating shaft is rotatably mounted on the top of the escalator, and a rotating handrail is rotatably mounted on the outside of the rotating shaft.
[0010] Preferably, a limiting plate is fixedly installed on one side of the rotating handrail, and a locking pin is slidably provided inside the limiting plate, with one end of the locking pin inserted into the interior of the escalator.
[0011] Preferably, a support column is fixedly installed inside the support platform, and the ladder is located inside the support platform.
[0012] Preferably, the first lead screw, the second lead screw, and the positive and negative lead sleeves are all made of high-strength steel.
[0013] Preferably, when the rotating platform rotates 90 degrees, the support shaft can be engaged inside the limiting member.
[0014] The working principle and beneficial effects of this utility model are as follows: the first and second lead screws can support the rotating platform and prevent the bearings from being damaged due to excessive tension. The positive and negative lead sleeves can make the support shaft more securely locked inside the limiting component, thereby preventing the rotating platform from rotating when the worker is working and thus preventing the worker from falling and getting injured. The locking pin can lock the rotating handrail when it is retracted, thereby blocking the retracted rotating platform and preventing the rotating platform from rotating due to accidental contact. The support column can fix the escalator inside the support platform, thereby making the escalator more secure. Attached Figure Description

[0024] Implementation
[0025] Please see Figure 1 -6, an auxiliary platform for loading and unloading rails on long rail transport trains, comprising: a support platform 1 and a ladder for climbing;
[0026] The top of the escalator 2 is provided with a bearing 3, and a rotating platform 4 is rotatably installed on the top of the escalator 2 via the bearing 3.
[0027] A support plate 5 is fixedly installed inside the support platform 1. A fixed shaft 6 is rotatably installed inside the support plate 5. A first lead screw 7 is fixedly installed outside the fixed shaft 6. A positive and negative threaded sleeve 8 is installed on the external thread of the first lead screw 7. A second lead screw 9 is installed on the internal thread of the positive and negative threaded sleeve 8. A support shaft 10 is fixedly installed at one end of the second lead screw 9.
[0028] A limiting component 11 is fixedly installed at the bottom of the rotating platform 4, and a groove 12 is provided inside the limiting component 11.
[0029] The technical solution provided in this embodiment is as follows: In use, the worker first walks onto the platform of the escalator 2, then pulls out the locking pin 16 to rotate the rotating platform 4 ninety degrees through the bearing 3, then moves the first lead screw 7 and the second lead screw 9 through the fixed shaft 6, and then the support shaft 10 is locked inside the limiting member 11. Then, the positive and negative threaded sleeve 8 is rotated to increase the gap between the first lead screw 7 and the second lead screw 9, thereby allowing the first lead screw 7 and the second lead screw 9 to support the rotating platform 4 through the limiting member 11 and the support shaft 10, reducing the force on the bearing 3 when the worker walks onto the rotating platform 4 and increasing the service life of the bearing 3. The space between the support platform 1 and the escalator 2 can also be used to place commonly used tools and equipment for long rail cars and commonly used tools and equipment for hoisting and maintenance, greatly improving the efficiency of safe space utilization in hoisting operations and providing convenient conditions for operation and maintenance.
[0030] Furthermore, a rotating shaft 13 is rotatably installed on the top of the escalator 2, and a rotating handrail 14 is rotatably installed on the outside of the rotating shaft 13.
[0031] Specifically, by rotating the handrail 14 and mounting it on the outside of the rotating shaft 13, the rotating platform 4 can be rotated out when the handrail 14 is rotated, so that the worker can stand on the rotating platform 4 to work.
[0032] Furthermore, a limit plate 15 is fixedly installed on one side of the rotating handrail 14, and a locking pin 16 is slidably provided inside the limit plate 15, with one end of the locking pin 16 inserted into the interior of the escalator 2.
[0033] Specifically, by inserting one end of the locking pin 16 into the interior of the escalator 2, the movement of the rotating handrail 14 can be restricted by the locking pin 16, thereby blocking the retracted rotating platform 4 and preventing the rotating platform 4 from rotating due to accidental contact.
[0034] Furthermore, a support column 17 is fixedly installed inside the support platform 1, and the ladder 2 is located inside the support platform 1.
[0035] Specifically, the escalator 2 can be fixedly installed inside the support platform 1 by the support column 17, thereby making the escalator 2 more stable.
[0036] Furthermore, the first lead screw 7, the second lead screw 9, and the positive and negative threaded sleeves 8 are all made of high-strength steel.
[0037] Specifically, the first lead screw 7, the second lead screw 9, and the positive and negative threaded sleeves 8, all made of high-strength steel, can support the rotating platform 4 and prevent the bearing 3 from being excessively damaged due to tension.
[0038] Furthermore, when the rotating platform 4 rotates 90 degrees, the support shaft 10 can be engaged inside the limiting member 11.
[0039] Specifically, by inserting the support shaft 10 into the limiting member 11, the first lead screw 7 and the second lead screw 9 can support the rotating platform 4 and prevent the rotating platform 4 from bending downward due to tension.
[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
