Description

Technical Field

[0001] The present invention belongs to the technical field of rail collection and unloading, and particularly relates to a rail anti-overturning and anti-sliding assembly for rail collection and unloading. Background Art

[0002] The rail transport vehicle includes wheels, a flatbed and a lifting device. The wheels cooperate with the rails on the railway to drive the rail transport vehicle to move forward; the flatbed is erected above the wheels and is used to place the rails; currently, for the situation that the rails are overturned and twisted during the collection and unloading process, and the rails slide along the slope during unloading on a slope, at present, a guiding frame is provided at one end of the flatbed, and a guiding groove is provided on the guiding frame. When unloading the rails, one end of the rails on the flatbed is transported into the guiding groove through the lifting device, and the bottom of the rail is in contact with the bottom of the guiding groove, and the rail moves longitudinally in the guiding groove. When one end of the rail contacts the ground, the rail transport vehicle is started to move forward, so that the rail gradually slides out of the guiding groove.

[0003] The width of the guiding groove is greater than the width of the rail. During the process of hoisting the rail into the guiding groove and the rail sliding in the guiding groove, the rail is prone to tilt in the guiding groove, causing the rail head to contact the side wall of the guiding groove; in addition, the length of the rail is relatively long, and at this time, the part of the rail on the flatbed does not tilt, and thus the rail itself twists, resulting in deformation or even overturning of the rail, seriously affecting the continuity and safety of the rail collection and unloading operation, and at the same time, the rail will also be damaged, affecting the quality of the rail; moreover, during the rail unloading process, there is a certain slope, resulting in the rail sliding along the slope, affecting the safety of the rail collection and unloading operation. Summary of the Invention

[0004] The present invention aims to provide a rail anti-overturning and anti-sliding assembly for rail collection and unloading, which integrates the functions of rail anti-overturning and anti-sliding, and has a high safety factor for rail collection and unloading, so as to solve the problems of rail overturning and twisting during the collection and unloading process, and rail sliding along the slope during unloading on a slope.

[0005] To this end, the technical solution adopted by the present invention is as follows: A steel rail anti-turning and anti-sliding assembly for loading and unloading rails, comprising an anti-turning and anti-sliding main frame installed on a long steel rail transport vehicle, a steel rail anti-turning mechanism and a steel rail anti-sliding mechanism installed on the anti-turning and anti-sliding main frame from front to back. The steel rail anti-turning mechanism includes a roller for supporting the longitudinal steel rail, a connecting rod assembly and an anti-turning side arm symmetrically arranged on the left and right sides of the roller. The inner and outer ends of the anti-turning side arm are not on a straight line, and the center is horizontally rotatably installed on the anti-turning and anti-sliding main frame. The anti-turning side arm is linked with the roller through the connecting rod assembly. The connecting rod assembly includes a supporting elastic member, a roller support seat, a rotating arm and a connecting rod. The bottom of the supporting elastic member is installed on the bottom plate of the anti-turning and anti-sliding main frame, and the top is connected to the end of the roller. The large head end of the roller support seat is hinged to the end of the roller and a plane is provided at the lower part. The small head end of the roller support seat extends backward and is fixedly connected with the bottom end of the rotating arm through a connecting rotating shaft passing through the anti-turning and anti-sliding main frame. The front and rear ends of the connecting rod are respectively hinged to the outer end of the anti-turning side arm and the top end of the rotating arm. When the longitudinal steel rail is placed on the roller, the roller sinks under the influence of the gravity of the steel rail, driving the bottom plane of the roller support seat to fit with the bottom plate of the anti-turning and anti-sliding main frame. The rotating arm pushes the outer end of the anti-turning side arm through the connecting rod, so that the anti-turning side arm rotates counterclockwise along the center, and the inner end of the anti-turning side arm approaches the steel rail, realizing the lateral limit of the steel rail. The steel rail anti-sliding mechanism includes an anti-sliding clamp with the jaw facing upward and a hydraulic cylinder for driving the anti-sliding clamp to clamp the lower part of the longitudinal steel rail.

[0006] As a preference of the above solution, a roller is installed at the inner end of the anti-turning side arm to avoid the steel rail from bumping and damaging the components. The included angle θ between the connecting line of the inner and outer end connection points and the center installation point of the anti-turning side arm is 150° - 170°. The inner and outer end points and the center point form a triangular structure, which is more stable and requires less driving force compared with the straight plate structure. The anti-turning and anti-sliding main frame is provided with an anti-turning side arm stop block. When the inner end of the anti-turning side arm approaches the steel rail to the maximum extent, its rear wall just abuts against the anti-turning side arm stop block, so as to maintain the stability of the state of the anti-turning side arms on both sides of the steel rail, and prevent the anti-turning side arms from rotating due to the movement of the steel rail, resulting in a change in the rail limit distance between the two anti-turning side arms and increasing the safety guarantee.

[0007] Further preferably, four anti-collision rollers are symmetrically installed on the anti-turning and anti-sliding main frame to prevent the side surface of the rail bottom from colliding with the anti-turning and anti-sliding main frame. During the process of loading and unloading the rail, due to the left and right swing of the steel rail, it will cause friction between the steel rail and the box body, generating grooves, and the steel rail may be stuck, which is not conducive to the loading and unloading of the steel rail and affects the service life of the anti-turning device at the same time. Therefore, adding anti-collision rollers can effectively ensure that the steel rail will not directly collide with the anti-turning and anti-sliding main frame and wear when it swings, and avoid the occurrence of the situation where the steel rail is stuck.

[0008] Further preferably, the supporting elastic member includes a spring mounting base and a supporting spring sleeved on the spring mounting base. The spring mounting base includes a base, an upper spring support seat, and a lower spring support seat sleeved on the lower part of the upper spring support seat. The base is fixedly installed on the bottom plate of the anti-overturning and anti-sliding main frame. The upper spring support seat is rotatably installed at the end of the roller, and the lower spring support seat is rotatably installed on the base, forming two rotatable points up and down for the supporting spring, which can make the supporting spring change flexibly, avoiding the situation that the supporting spring can only vertically lift the roller and the roller support seat, resulting in a conflict at the rotating shaft and unable to lift. The design is ingenious and reasonable.

[0009] Further preferably, a spring seat rotating shaft is provided at the bottom of the lower spring support seat, and the base is provided with notches for installing both ends of the spring seat rotating shaft, so that the lower spring support seat has a rotation range of 10° to 40°. The design is reasonable and the structure is flexible.

[0010] Further preferably, a wear plate is provided at the position corresponding to the lower side wall of the rail for the anti-sliding clamp, which can effectively increase the friction between the anti-sliding clamp and the rail. When the telescopic rod of the hydraulic cylinder pushes the jaws of the anti-sliding clamp upward to clamp the lower part of the rail, the design is reasonable.

[0011] The beneficial effects of the present invention are as follows:

[0012] (1) Compared with the current situation that only considers the anti-overturning requirement of the rail, this solution combines the actual slope during rail unloading and needs to prevent the rail from sliding along the slope. An additional rail anti-sliding mechanism is added. By pushing the jaws of the anti-sliding clamp upward by the telescopic rod of the hydraulic cylinder to clamp the lower part of the rail, the situation of the rail sliding along the slope can be effectively avoided, realizing the integration of the functions of anti-overturning and anti-sliding of the rail, and having strong practicability.

[0013] (2) With the help of the gravity of the rail, when the roller sinks, the anti-overturning side arm is linked to retract inward through the connecting rod assembly to limit the lateral movement space of the rail, realizing the automatic inward and outward retraction of the anti-overturning side arm. The concept is ingenious. The inner and outer ends of the anti-overturning side arm are not on the same straight line, and the center is horizontally rotatably installed on the anti-overturning and anti-sliding main frame. The rotating arm pushes the outer end of the anti-overturning side arm through the connecting rod, so that the inner end of the anti-overturning side arm approaches the rail. With little driving force, the rail can be easily limited, effectively preventing the rail from tipping and twisting during the process of unloading and loading the rail. The anti-overturning effect is good, and the safety factor of unloading and loading the rail is high.

[0014] (3) The bottom of the supporting elastic member is installed on the bottom plate of the anti-overturning and anti-sliding main frame, and the top is connected to the end of the roller. The supporting elastic member ensures that the roller returns to its position after sinking and provides a supporting point; the large head end of the roller support seat is hinged to the end of the roller and a plane is provided at the lower part. When the plane fits the bottom plate of the anti-overturning and anti-sliding main frame, the roller support seat provides a supporting point after the roller sinks. In this way, there is a supporting point whether the roller sinks or returns, preventing the roller from being misaligned and fully ensuring the long service life of the overall structure.

[0015] (4) The small end of the roller support seat extends backward and is fixedly connected to the bottom end of the swing arm through a connecting rotating shaft passing through the anti-overturning and anti-sliding main frame, ensuring that the angle between the roller support seat and the swing arm is fixed and can rotate along the connecting rotating shaft. The design is reasonable, and the two ends of the roller support seat adopt a large-small head structure to ensure the structural stability; the front and rear ends of the connecting rod are respectively hinged to the outer end of the anti-overturning side arm and the top end of the swing arm, with flexible rotation and the structure interlocking, showing a clever concept.

[0016] In summary, it has the advantages of strong practicability, good anti-overturning effect, high safety factor for rail loading and unloading, interlocking structure, and clever concept. BRIEF DESCRIPTION OF THE DRAWINGS
