Description

Technical Field

[0001] This application relates to the field of rail transit maintenance technology, and in particular to rail conveying devices and rail unloading vehicles. Background Technology

[0002] With the increasing intensity and frequency of railway transportation, the available maintenance windows for railway repairs are decreasing. Furthermore, as railway speeds improve, the length of seamless tracks in my country is also gradually increasing. To reduce the time and maintenance windows required for rail replacement, short rails are now typically welded into longer rails offline, which are then transported to the repair section for replacement.

[0003] Because the rails are quite long and a single rail can weigh between half a ton and several tons, manual labor would be too strenuous for unloading and loading them. Therefore, using mechanized methods to transport long rails is the key and challenging aspect of the rail replacement process.

[0004] In the current technology, rail conveying devices mainly work in conjunction with hoisting devices. The hoisting device lifts the rails onto the rail conveying device for transport. However, this structure requires the use of a hoisting device, which is complicated to operate. Furthermore, the rail conveying device relies mainly on the hoisting device to support the rails, thus affecting the efficiency and accuracy of hoisting long rails.

[0005] In view of the above, this application is hereby submitted. Summary of the Invention

[0009] A vertical clamping mechanism is connected to a lateral moving mechanism, forming a space between them for the rail to pass through; it can move vertically above the rail to clamp it to the lateral moving mechanism.

[0010] A rail drive mechanism, connected to a vertical clamping mechanism; when the rail is clamped, it is used to drive the rail to move longitudinally relative to external equipment.

[0024] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

This embodiment provides a rail conveying device.

[0026] Define the width direction of the frame as the transverse direction, the length direction of the frame as the longitudinal direction, and the direction perpendicular to the plane containing the transverse and longitudinal directions as the vertical direction.

[0027] The rail conveying device 3 includes a lateral moving mechanism 301, a vertical pressing mechanism 302, and a rail driving mechanism 304.

[0028] A transverse frame 305 is provided between the transverse moving mechanism 301 and the external equipment. The transverse frame 305 can be moved relative to the external equipment to a preset position to support the rail. A vertical clamping mechanism 302 is connected to the transverse moving mechanism 301, forming a space between them for the rail to pass through. It can move vertically above the rail to clamp it against the transverse moving mechanism 301. A rail driving mechanism 304 is connected to the vertical clamping mechanism 302. Under the clamped rail condition, it drives the rail to move longitudinally relative to the external equipment. It should be noted that the external equipment in this application can be a train frame.

[0029] In practice, a lateral moving mechanism 301 is installed, allowing the rail conveying device to move laterally relative to the external equipment to adjust its position for receiving the rail. After receiving the rail, a vertical clamping mechanism 302 clamps it, and a rail driving mechanism 304 drives the rail longitudinally relative to the external equipment. The rail conveying device provides the power for longitudinal rail unloading, and compared to a robotic arm, it has a simpler structure and lower manufacturing and maintenance costs.

[0030] The rail conveying device has a lateral movement function, which facilitates the acceptance of rails and can also adjust the unloading position; the vertical clamping mechanism 302 can move as a whole, allowing the rail belt clamp to pass directly, improving work efficiency.

[0031] As an embodiment of this application, a rail transport vehicle is provided, which also includes an auxiliary rolling mechanism 303.

[0032] In specific implementation, the auxiliary rolling mechanism 303 can be multiple rollers installed on the transverse moving mechanism 301. The rollers extend in the transverse direction and are parallel to the transverse moving mechanism 301. When the rail is transported, the rollers are used to support the rail and reduce the friction force on the rail when it moves longitudinally.

[0033] The lateral movement mechanism 301 includes a lateral guide rail 311, a base 312, and a base drive member 314.

A lateral slider 313 is disposed on the base 312, and the lateral slider 313 slides in engagement with the lateral guide rail 311. It can move in the lateral direction relative to the lateral frame 305 to a preset position to carry the steel rail transmitted in the longitudinal direction. The base drive member 314 is connected to the base 312 and is used to provide the driving force for the base 312 to move relative to the lateral frame 305.

[0034] In specific implementation, the base drive component 314 drives the base 312 to move along the transverse guide rail 311 set on the transverse frame 305, thereby realizing the transverse movement of the rail conveying device relative to the external equipment, so as to adjust the position for easy acceptance of the rail. The base drive component 314 can be a drive cylinder, or other drive components or drive structures that can provide power.

In specific implementations, the clamping drive component 325 can be a hydraulic cylinder or other drive component or drive structure that can provide power.

[0039] As an embodiment of this application, a rail transport vehicle is provided, and the vertical clamping mechanism 302 further includes a top connecting bracket 326 and a bottom connecting bracket 327.

[0040] The top connecting bracket 326 is disposed on the clamping frame 322; the bottom connecting bracket 327 is disposed on the lateral moving mechanism 301 and is disposed corresponding to the top connecting bracket 326; the bottom end of the clamping drive component 325 is connected to the bottom connecting bracket 327 and the top end is connected to the top connecting bracket 326.

[0041] During implementation, the clamping drive 325 drives the clamping frame 322 to move vertically via the top connecting bracket 326.

[0042] As an embodiment of this application, a rail transport vehicle is provided, and the rail drive mechanism 304 includes a clamping wheel 341 and a clamping wheel drive component 342.

[0043] The clamping roller 341 is mounted on the vertical clamping mechanism 302 via a clamping roller bracket, and the clamping roller 341 is mounted on the clamping bracket; it is used to clamp the rail to the lateral moving mechanism 301; the output end of the clamping roller drive 342 is connected to the clamping roller 341 via a transmission component; in the rail clamping state, it is used to drive the clamping roller 341 to rotate to provide the driving force for the rail to move longitudinally.

[0044] In practice, the clamping wheel drive component 342 can be a drive motor or other drive components capable of driving the clamping wheel 341 to rotate. The clamping wheel drive component 342 and the clamping wheel 341 can be connected by a belt or by other transmission components capable of transmitting power.

[0045] As a specific embodiment, the clamping wheel 341 clamps the rail to the auxiliary rolling mechanism 303 on the lateral moving mechanism 301; in the clamped state, the clamping wheel drive 342 drives the clamping wheel 341 to rotate to provide the driving force for the rail to move longitudinally.
