It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. The technical solution of the present invention is described in detail below in combination with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0028] See also Figures 1 to 3 This embodiment proposes a train tipping machine safety stopper, including a horizontal force unit 1, a tension transmission unit 2, a stopper 3 and an auxiliary spring force storage unit 4; the horizontal force unit 1 is located in the middle position between the two tracks 6, and the horizontal force unit 1 includes a first roller 11, a roller fixing bracket 12 and a push connecting plate 13; the roller fixing bracket 12 is arranged parallel to the track, and one end of the roller fixing bracket 12 is a U-shaped structure, and a wheel axle is connected inside the U-shaped structure, and the first roller 11 is rotatably connected to the wheel axle; the first roller 11 is used for use with the transfer platform 5 located on one side of the track 6; the other end of the roller fixing bracket 12 is symmetrically hinged to two push connecting plates 13. In order to improve the stability of the device, a fixed box 7 is arranged on the ground between the two tracks 6, and the fixed box 7 is connected to a hinged connecting shaft through a bearing seat, and the roller fixing bracket 12 is rotatably connected to the two push connecting plates 13 through the hinged connecting shaft.

[0029] The tension transmission unit 2 includes a pull rod 22, and both ends of the pull rod 22 are respectively connected with U-shaped fixing clips 21, and both ends of the pull rod 22 are provided with screw threads 24, and the pull rod 22 is threadedly connected with the U-shaped fixing clips 21 at both ends through the screw threads 24; a square 23 is provided on the pull rod 22. The function of the square 23 and the screw thread 24 is to adjust the distance between the U-shaped fixing clips 21 at both ends of the pull rod 22, and then the height of the stopper 3 from the rail surface can be adjusted.

[0030] The U-shaped fixing clip 21 at one end of the pull rod 22 is rotatably connected to the end of the push link plate 13 away from the roller fixing bracket 12 through a pin, and the U-shaped fixing clip 21 at the other end of the pull rod 22 is hinged to the stopper 3 through a hinged link plate assembly; specifically, the hinged link plate assembly includes a horizontal push pull plate 27, a vertical lifting pull plate 26 and a pin-fixing copper sleeve 25; a pin 28 is connected through the pin-fixing copper sleeve 25; one end of the horizontal push pull plate 27 is rotatably connected to the U-shaped fixing clip 21 at the other end of the pull rod 22 through a pin, and the other end of the horizontal push pull plate 27 is rotatably connected to one end of the pin 28; one end of the vertical lifting pull plate 26 is rotatably connected to the stopper 3, and the other end of the vertical lifting pull plate 26 is rotatably connected to the other end of the pin 28. The pin-fixing copper sleeve 25 is arranged at the bottom of the track 6, the stopper 3 and the vertical lifting pull plate 26 are located outside the track 6, and the horizontal push pull plate 27 and the pull rod 22 are arranged inside the track 6. By pushing the pull plate 27 horizontally, the pin fixes the copper sleeve 25 and vertically lifts the pull plate 26, so as to convert the horizontal pulling force into the vertical lifting force.

[0031] One end of the stopper 3 is a fixed counterweight block 31, and one side of the fixed counterweight block 31 can be fixed with different numbers of movable counterweight blocks 32 by means of magnetic attraction or the like to adjust the weight of the stopper 3. The fixed counterweight block 31 of the stopper 3 lifts the other end of the stopper 3 by gravity, and the movable counterweight block 32 can be added to increase the counterweight, and the increase of the counterweight increases the gravity to overcome the friction of the pins at various locations to ensure that the roller fixing bracket 12 of the horizontal force-bearing unit 1 can complete the rebound and extension.

[0032] In order to further overcome the friction of the pins at various locations on the roller fixing bracket 12 of the horizontal force-bearing unit 1 when it can complete the rebound extension, an auxiliary spring force storage unit 4 is added. The auxiliary spring force storage unit 4 is located below the bottom of the other end of the stopper 3; the auxiliary spring force storage unit 4 includes an embedded steel plate 41, a compression spring 42, a pressure plate 43, a positioning shaft 44, a roller bracket 45 and a second roller 46; the embedded steel plate 41 is set on the ground outside the track 6, the bottom end of the compression spring 42 is connected to the embedded steel plate 41, the top end of the compression spring 42 is connected to the pressure plate 43, the bottom of the pressure plate 43 is connected to the positioning shaft 44, and the positioning shaft 44 is located in the compression spring 42; the pressure plate 43 is provided with a roller bracket 45, and the second roller 46 is rotatably connected to the roller bracket 45 through a connecting shaft.

[0033] The working principle of the safety stopper of the train tipping machine described in the utility model is:

[0034] When the transfer platform 5 is aligned in place from one side of the track 6, the first roller 11 of the horizontal force-bearing unit 1 is subjected to the sliding thrust from one side of the transfer platform 5, and the roller fixing bracket 12 rotates around the hinged connection axis, thereby driving the pushing connecting plate 13 to rotate around the hinged connection axis toward the side of the transfer platform 5, forming a horizontal pulling force on the pull rod 22, and the pull rod 22 drives the horizontal pushing pull plate 27 to rotate, thereby driving the vertical lifting pull plate 26 to rotate around the pin shaft 28 toward the side of the auxiliary spring storage unit 4, so that the stopper 3 is in a horizontal state and parallel to the rail surface. At this time, the car body is pushed from the transfer platform 5 into the track 6 normally without obstruction.

[0035] On the contrary, when the car body is pushed into the track 6, the car transfer platform 5 returns, and the stopper 3 is affected by the gravity of the fixed counterweight block 31 and the compression spring 42, and the stopper 3 tilts (the stopper completes the action of preventing the car from sliding), driving the tension transmission unit 2 to generate thrust, pushing the horizontal force unit 1 out, completing the action reset, and this action is repeated to complete the unloading of the train car body.

[0036] The above content is a further detailed description of the utility model in combination with a specific preferred implementation method. It cannot be determined that the specific implementation methods of the utility model are limited to this. For ordinary technicians in the technical field to which the utility model belongs, they can make several simple deductions or substitutions without departing from the utility model, which should be regarded as belonging to the utility model and the scope of patent protection determined by the submitted claims.
