[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 The utility model provides an embodiment: a rail locking device for a rail crane, comprising a fixed beam 1 and a moving beam 2, the fixed beam 1 and the moving beam 2 are fixedly connected to the outside with a fixing piece 3, the fixing piece 3 is fixedly connected to the inside with a sleeve 4, the front end right side of the moving beam 2 is fixedly connected to a hydraulic cylinder 5, the inside of the right sleeve 4 is slidably connected to a push rod 6, the inside of the left sleeve 4 is slidably connected to the outside of the push rod 6, the inside of the moving beam 2 is slidably connected to the outside of the push rod 6, and the output end of the hydraulic cylinder 5 is fixedly connected to the right side of the push rod 6.

[0025] Specifically, the fixed beam 1 and the movable beam 2 respectively fix the two fixing parts 3, so that the position of the fixing parts 3 is fixed, the fixing parts 3 fix the sleeve 4, so that the position of the sleeve 4 is fixed, the movable beam 2 and the sleeve 4 limit the push rod 6, so that the push rod 6 is stable when moving, and the movable beam 2 fixes the hydraulic cylinder 5, so that the hydraulic cylinder 5 can stably drive the push rod 6 to move, and move the push rod 6 to the inside of the left sleeve 4, thereby locking the fixed beam 1 and the movable beam 2.

[0026] Reference Figure 1-Figure 3 The left sleeve 4 is internally slidably connected to a limiting block 7, and the left side of the limiting block 7 is fixedly connected to a moving rod 8, the inside of the left sleeve 4 is slidably connected to the outside of the moving rod 8, and the outside of the moving rod 8 is sleeved with a spring 9, the inside of the left sleeve 4 is fixedly connected to the left side of the spring 9, the left side of the limiting block 7 is fixedly connected to the right side of the spring 9, the bottom end of the limiting block 7 is fixedly connected to a sliding rod 10, the inside of the left sleeve 4 is slidably connected to the outside of the sliding rod 10, the inside of the fixing member 3 is rotatably connected to a rotating rod 11, an annular groove 12 is provided on the outside of the left rotating rod 11, the outside of the sliding rod 10 is slidably connected to the inside of the annular groove 12, the right end of the left rotating rod 11 is fixedly connected to a protrusion 13, and a groove 14 is provided on the right side of the right rotating rod 11, the outside of the protrusion 13 is engaged with the inside of the groove 14, and the bottom end of the rotating rod 11 is fixedly connected to a baffle 15.

[0027] Specifically, the left sleeve 4 has a limiting effect on the limit block 7, the moving rod 8 and the sliding rod 10, so that the limit block 7, the moving rod 8 and the sliding rod 10 are stable when moving. The left sleeve 4 and the limit block 7 have a fixing effect on the spring 9, so that the spring 9 can stably perform elastic deformation. The sliding rod 10 slides in the annular groove 12, thereby driving the left rotating rod 11 to rotate. The protrusion 13 on the left rotating rod 11 is engaged with the groove 14 on the right rotating rod 11, so that the rotation of the left rotating rod 11 can drive the right rotating rod 11 to rotate. The fixing member 3 has a limiting effect on the rotating rod 11, so that the rotating rod 11 is stable when rotating.

[0028] Reference Figure 2 and Figure 4 A buffer assembly 16 is provided on the outside of the baffle 15, and the buffer assembly 16 plays a buffering and protective role for the baffle 15. The buffer assembly 16 includes two mounting grooves 1601, and the two mounting grooves 1601 are respectively opened inside the baffle 15. The upper and lower sides of the interior of the mounting groove 1601 are slidably connected to the limiting block 2 1602, and the interior of the mounting groove 1601 is slidably connected to the exterior of the limiting block 2 1602. The adjacent side of the limiting block 2 1602 on the upper and lower sides is fixedly connected with a spring 2 1603, and the separated ends of the limiting blocks 2 1602 on the left and right sides are rotatably connected with a connecting rod 1604, the interior of the mounting groove 1601 is slidably connected to the exterior of the connecting rod 1604, and the separated sides of the connecting rods 1604 on the left and right sides are rotatably connected with a buffer plate 1605.

[0029] Specifically, the mounting groove 1601 limits the limit block 1602 and the connecting rod 1604, so that the limit block 1602 and the connecting rod 1604 will not deviate when moving. The limit blocks 1602 on the upper and lower sides fix the spring 1603, so that the spring 1603 can stably perform elastic deformation. One end of the connecting rod 1604 is rotatably connected to the limit block 1602, and the other end is rotatably connected to the buffer plate 1605, so that when the buffer plate 1605 is subjected to impact force, it can drive one end of the connecting rod 1604 to move, and the other end drives the limit block 1602 to move to the nearby side.

[0030] Working principle: when it is necessary to lock the fixed beam 1 and the movable beam 2, when the movable beam 2 moves to the appropriate position, the hydraulic cylinder 5 is started to drive the push rod 6 to move to the left sleeve 4 for locking, thereby pushing the limit block 7 to move to the left, and then driving the movable rod 8 to move with it, thereby squeezing the spring 9 to make elastic deformation, and then driving the slide bar 10 to move to the left, so that the movement of the slide bar 10 in the annular groove 12 will drive the left rotating rod 11 to rotate, and then the right rotating rod 11 is driven to rotate in the groove 14 by the protrusion 13, thereby driving the baffle 15 to rotate, so that the lifting trolley can pass smoothly. After passing through, the hydraulic cylinder 5 is started to retract the push rod 6, so that the baffle 15 can be driven to return to the previous position by the deadweight of the baffle 15 and the reset activity of the spring 9, so that the lifting trolley can be blocked and protected;

[0031] In addition, when an operational error causes the lifting trolley to hit the baffle 15, the impact force will cause the buffer plate 1605 to move inward, thereby driving one end of the connecting rod 1604 to move with it, and the other end will squeeze the upper and lower limit blocks 1602 to move toward the closer side, thereby squeezing the spring 1603 to make an elastic deformation, so that the reset activity of the spring 1603 can drive the various structures to rebound, thereby buffering the impact force of the lifting trolley.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
