Description

Technical Field

[0001] This utility model belongs to the field of train loading and unloading technology, and specifically relates to a train loading platform. Background Technology

[0002] In the loading of freight trains, the railway system requires that there be no obstacles within a certain range around the carriages; this range is called the clearance. Due to the existence of the clearance, a gap of approximately 0.9 meters wide exists between the surrounding platform and the freight carriages. This gap not only affects the normal passage of personnel but also poses a safety risk of falls from a height.

[0003] In actual production, temporary platforms are often used to solve this problem. However, temporary platforms are inconvenient to store and difficult to retrieve from indoors. Furthermore, a single platform may not be able to accommodate the gap between the platform and the carriage, resulting in poor adaptability. Utility Model Content

[0004] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a train loading platform that can be folded up or lowered in place, and the platform width can be adjusted according to the gap width between the platform and the carriage.

[0005] The technical solution adopted in this utility model is as follows: A train loading platform includes a steel column and a rotating platform. The steel column is fixed to the platform near the rails, and the rotating platform is rotatably connected to the platform near the rails. A telescopic platform is slidably connected to the rotating platform, and a locking mechanism for locking with the rotating platform is provided on the telescopic platform. Steel cables are connected to both the rotating platform and the telescopic platform, and a steel cable tensioner is connected to the other end of the steel cable for tightening the steel cable. The steel cable tensioner is installed on the steel column.

[0006] The rotating platform of this utility model is directly rotatably connected to the edge of the turntable. When the steel cable is wound up by the steel cable tensioner, the steel cable pulls the rotating platform and the telescopic platform to rotate together to stand upright. This avoids the platform occupying the boundary area and allows the platform to be stored in place, making operation more convenient.

[0007] When the vehicle stops at the platform, the steel cable is lowered via the cable tensioner, and the rotating platform and telescopic platform rotate to a horizontal position. Based on the width of the gap between the platform and the vehicle, the telescopic platform extends a predetermined distance relative to the rotating platform, and then a locking mechanism locks the telescopic platform relative to the rotating platform, creating a passageway. The rotating platform and telescopic platform effectively fill the gap between the platform and the vehicle, preventing obstruction of normal passenger passage and mitigating the safety risks of falls from heights.

[0008] As a preferred embodiment of this utility model, the locking mechanism includes a buckle plate, one end of which is rotatably connected to the edge of the telescopic platform, and the other end of which is fixed with a duckbill plate, which is perpendicular to the buckle plate. A locking groove is provided on the edge of the rotating platform, and the other end of the duckbill plate is engaged in the locking groove. A spring is connected to the duckbill plate, and the other end of the spring is connected to the bottom of the telescopic platform.

[0009] When the telescopic platform needs to be extended or retracted relative to the rotating platform, pull out the latch plate. The duckbill plate rotates with the latch plate and disengages from the locking groove, allowing the telescopic platform to move freely relative to the rotating platform. After the telescopic platform extends the required distance, release the latch plate. Under the restoring force of the spring, the duckbill plate rotates to the position where it engages with the locking groove, thus locking the telescopic platform.

[0010] As a preferred embodiment of this utility model, the buckle plate is connected to a handle for pulling the duckbill out of the buckle groove.

[0011] As a preferred embodiment of this utility model, each of the two telescopic platforms is provided with two locking mechanisms, and locking grooves are provided on both sides of the rotating platform. One end of several duckbill plates on the same side is engaged in the same locking groove. The duckbill plates of the two locking mechanisms on one side can better engage with the locking groove, preventing the telescopic platform from sliding relative to the rotating platform.

[0012] In a preferred embodiment of this invention, the upper surface of the rotating platform is provided with a groove, and a pulley is installed at the bottom of the telescopic platform, with the pulley fitted inside the groove. The groove of the rotating platform limits the movement of the pulley of the telescopic platform, thereby ensuring that the telescopic platform always slides in a straight line on the rotating platform and preventing the telescopic platform from detaching from the rotating platform. Furthermore, the pulley rolls within the groove, which reduces the frictional force when the telescopic platform moves.

[0013] As a preferred embodiment of this utility model, both the upper surface of the rotating platform and the upper surface of the telescopic platform are provided with grating plates. The grating plates can play a role in preventing slippage and ensuring the safety of personnel walking on the platform.

[0014] As a preferred embodiment of this utility model, the cable tensioner includes a fixed shaft fixed to a steel column, a rotating sleeve sleeved on the fixed shaft, and a cable groove provided on the rotating sleeve, with the cable wound inside the cable groove. When the rotating sleeve is rotated, the cable is wound inside the cable groove, allowing the rotating platform and the telescopic platform to rotate to a vertical position, achieving the purpose of in-situ storage. As a preferred embodiment of this utility model, the rotating bushing is fixed with a number of pins, and the steel column is provided with a number of pin holes, into which the pins are inserted. After the steel cable is wound to a certain length, the pins on the rotating bushing are inserted into the pin holes on the steel column to fix the rotating bushing. At this time, the rotating platform and the telescopic platform can stay at a certain angle position.

[0015] As a preferred embodiment of this utility model, the number of pins and pin holes are three, and the three pins and three pin holes are evenly distributed around the fixed axis along the circumference.

[0016] As a preferred embodiment of this utility model, a handle is fixed on the rotating bushing. The rotating bushing is operated by the handle, which facilitates operation.

[0017] The beneficial effects of this utility model are as follows: 1. The rotating platform of this utility model is directly rotatably connected to the edge of the turntable. When the steel cable is wound up by the steel cable tensioner, the steel cable pulls the rotating platform and the telescopic platform to rotate together to stand upright. This avoids the platform occupying the boundary area and allows the platform to be stored in place, making the operation more convenient.

[0018] 2. When the vehicle stops at the platform, the steel cable is lowered using the cable tensioner, and the rotating platform and telescopic platform rotate to a horizontal position. Based on the width of the gap between the platform and the vehicle, the telescopic platform extends a predetermined distance relative to the rotating platform, and then the locking mechanism locks the telescopic platform relative to the rotating platform, establishing a passageway. The rotating platform and telescopic platform effectively fill the gap between the platform and the vehicle, preventing obstruction of normal personnel passage and mitigating the safety risks of falls from heights.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other.

[0023] like Figure 1 , Figure 2 and Figure 6 As shown, the train loading platform of this embodiment includes a steel column 1 and a rotating platform 2. The steel column 1 is fixed to the platform near the rails. The rotating platform 2 is rotatably connected to the platform near the rails. A telescopic platform 3 is slidably connected to the rotating platform 2. The telescopic platform 3 is provided with a locking mechanism 4 for locking with the rotating platform 2. Steel cables 5 are connected to both the rotating platform 2 and the telescopic platform 3. The other end of the steel cable 5 is connected to a steel cable tensioner 6 for tightening the steel cable 5. The steel cable tensioner 6 is installed on the steel column 1.

[0024] The rotating platform 2 of this utility model is directly rotatably connected to the edge of the turntable. When the steel cable 5 is wound up by the steel cable tensioner 6, the steel cable 5 pulls the rotating platform 2 and the telescopic platform 3 to rotate together to stand upright. This avoids the platform occupying the boundary area and allows the platform to be stored in place, making the operation more convenient.

[0025] When the vehicle stops at the platform, the steel cable 5 is lowered via the steel cable tensioner 6, causing the rotating platform 2 and the telescopic platform 3 to rotate to a horizontal position. Based on the width of the gap between the platform and the vehicle, the telescopic platform 3 extends a predetermined distance relative to the rotating platform 2, and then the locking mechanism 4 locks the telescopic platform 3 relative to the rotating platform 2, establishing a passageway. The rotating platform 2 and the telescopic platform 3 effectively fill the gap between the platform and the vehicle, preventing obstruction of normal personnel passage and mitigating the safety risks of falls from heights.

[0026] Specifically, such as Figure 3As shown, the locking mechanism 4 includes a latching plate 41, one end of which is rotatably connected to the edge of the telescopic platform 3, and the other end of which is fixed with a duckbill plate 42. The duckbill plate 42 is perpendicular to the latching plate 41. A locking groove 21 is provided on the edge of the rotating platform 2, and the other end of the duckbill plate 42 is engaged in the locking groove 21. A spring 43 is connected to the duckbill plate 42, and the other end of the spring 43 is connected to the bottom of the telescopic platform 3. The locking groove 21 is a long strip groove arranged along the side of the rotating platform 2.

[0027] When the telescopic platform 3 needs to be extended or retracted relative to the rotating platform 2, the latch plate 41 is pulled outward. The duckbill plate 42 rotates with the latch plate 41 and disengages from the locking groove 21, allowing the telescopic platform 3 to move freely relative to the rotating platform 2. After the telescopic platform 3 extends the required distance, the latch plate 41 is released. Under the restoring force of the spring 43, the duckbill plate 42 rotates to the position where it engages with the locking groove 21, thus locking the telescopic platform 3.

[0028] The buckle plate 41 is connected to a handle 44 for pulling the duckbill plate 42 out of the buckle groove 21.

[0029] The telescopic platform 3 is equipped with two locking mechanisms 4 on each side, and the rotating platform 2 has locking grooves 21 on both sides. One end of several duckbill plates 42 on the same side is engaged in the same locking groove 21. The duckbill plates 42 of the two locking mechanisms 4 on one side can better engage with the locking grooves 21, preventing the telescopic platform 3 from sliding relative to the rotating platform 2.

[0030] Furthermore, the upper surface of the rotating platform 2 is provided with a groove 22, and the bottom of the telescopic platform 3 is equipped with a pulley 31, which is fitted into the groove 22. The groove 22 of the rotating platform 2 limits the pulley 31 of the telescopic platform 3, thereby ensuring that the telescopic platform 3 always slides in a straight line on the rotating platform 2 and preventing the telescopic platform 3 from falling off the rotating platform 2. In addition, the pulley 31 rolls within the groove 22, which can reduce the friction when the telescopic platform 3 moves.

[0031] like Figure 4 As shown, both the upper surface of the rotating platform 2 and the upper surface of the telescopic platform 3 are provided with grating plates 7. The grating plates 7 serve as anti-slip surfaces, ensuring the safety of personnel walking on the platforms.

[0032] Specifically, such as Figure 5 As shown, the cable tensioner 6 includes a fixed shaft 61 fixed to the steel column 1, a rotating sleeve 62 sleeved on the fixed shaft 61, and a cable groove 63 provided on the rotating sleeve 62. One end of the cable 5 is fixed in the cable groove 63 and the cable 5 is wound in the cable groove 63. When the rotating sleeve 62 is rotated, the cable 5 is wound in the cable groove 63, so that the rotating platform 2 and the telescopic platform 3 can rotate to a vertical position, achieving the purpose of in-situ storage.

[0033] To facilitate the fixing of the rotating bushing 62, a number of pins 64 are fixed on the rotating bushing 62, and a number of pin holes 11 are provided on the steel column 1. The pins 64 are inserted into the pin holes 11. After the steel cable 5 is wound to a certain length, the pins 64 on the rotating bushing 62 are inserted into the pin holes 11 on the steel column 1 to fix the rotating bushing 62. At this time, the rotating platform 2 and the telescopic platform 3 can stay at a certain angle position.

[0034] The number of pins 64 and pin holes 11 is three each, and the three pins 64 and three pin holes 11 are evenly distributed around the fixed shaft 61 along the circumference.

[0035] A handle 65 is fixed on the rotating bushing 62. The rotating bushing 62 is rotated by the handle 65, which facilitates operation. When rotating the rotating bushing 62, first pull out the rotating bushing 62 by the handle 65, so that the needle 64 is disengaged from the needle hole 11, and then shake the handle 65 so that the steel cable 5 can be wound in the steel cable groove 63.

[0036] This utility model is not limited to the above-mentioned optional embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that falls within the scope of the claims of this utility model shall be protected by this utility model.
