[0033] Embodiment: This embodiment aims to provide a gantry crane running track end stop structure, the main function of which is to effectively buffer the inertial impact force generated when the gantry crane travels to the end of the track, thereby ensuring the safe travel of the gantry crane.

[0034] Reference Figure 1 、 Figure 2 、 Figure 3As shown, the main components of the end stop structure of the gantry crane walking track are: a blocking plate, a pair of wing plates 3 and a buffer assembly, wherein the blocking plate is divided into two types: a flexible blocking plate 1 and a rigid blocking plate 2. The flexible blocking plate 1 and the rigid blocking plate 2 are both vertically arranged on the end of the I-shaped track, and a U-shaped notch adapted to the top plate of the track is centrally provided at the bottom of the flexible blocking plate 1 and the bottom of the rigid blocking plate 2. The width of the U-shaped notch matches the width of the top plate of the track, so that the lower end of the flexible blocking plate 1 can extend to the position corresponding to the web of the track, and the lower end of the rigid blocking plate 2 contacts the upper plate surface of the bottom plate of the track, wherein the rigid blocking plate 2 is spaced apart on the back of the flexible blocking plate 1 so that the rigid blocking plate 2 is closer to the end of the track; The blocking plate 2 has an impedance block 12 protruding horizontally toward the web of the track. The impedance block 12 can be welded to the rigid blocking plate 2. The top of the impedance block 12 abuts against the lower surface of the top plate of the track, and the bottom abuts against the upper surface of the bottom plate of the track. The impedance block 12 enhances the gripping ability of the rigid blocking plate 2 and the track, so that the rigid blocking plate 2 will not be displaced on the track, thereby ensuring the blocking ability of the rigid blocking plate 2. The lower end of the rigid blocking plate 2 is provided with a positioning plate 7 extending in the front and rear directions, and the positioning plate 7 is fastened to the bottom plate of the track and the hardened ground at the same time by the anchor bolt 8. Specifically, the anchor bolt 8 vertically penetrates the positioning plate 7 and the bottom plate of the track in sequence and is then threadedly connected to the hardened ground, thereby fixing the rigid blocking plate 2 by the anchor bolt 8.

[0035] Wing plates 3 are vertically welded on both sides of the back side of the flexible barrier plate 1. The upper and lower ends of the wing plates 3 are flush with the upper and lower ends of the flexible barrier plate 1 respectively, and buffer slots 5 are vertically opened on the top of the two wing plates 3; a connecting shaft protrudes horizontally toward the web of the track at the joint between the flexible barrier plate 1 and the wing plates 3. The connecting shaft is not shown in the figure. The external rotating sleeve of the connecting shaft is equipped with a roller 4, and the walking surface of the roller 4 is against the lower plate surface of the top plate of the track, so that the flexible barrier plate is prevented from leaving the top plate of the track by the roller 4.

[0036] The buffer assembly includes: a guide column 6, a force transmission plate 9, a pressure plate 10 and a spring 11. The guide column 6 is vertically welded inside the buffer slot 5 and centered. The force transmission plate 9 is obliquely placed between the flexible barrier plate 1 and the rigid barrier plate 2, and the high end of the force transmission plate 9 is facing the flexible barrier plate 1 and the low end is facing the rigid barrier plate 2. The lower end of the force transmission plate 9 is hinged to the rigid barrier plate 2, and the lower end of the force transmission plate 9 is adjacent to the upper plate surface of the track top plate. The pressure plate 10 is horizontally placed between the two wing plates 3 so that the end of the pressure plate 10 is correspondingly slidably mounted on the outside of the guide column 6. The high end of the force transmission plate 9 is also located between the two wing plates 3 so that the high end of the force transmission plate 9 is hinged to the lower plate surface of the pressure plate 10. The spring 11 is located above the pressure plate 10 so that the spring 11 is correspondingly mounted on the outside of the guide column 6.

[0037] When the flexible blocking plate 1 is impacted by the inertia of the gantry crane, the flexible blocking plate 1 will move along the track toward the rigid blocking plate 2, and the high end of the force transmission plate 9 will gradually rise under the action of the flexible blocking plate 1, thereby pushing the pressure plate 10 to move toward the top of the buffer slot 5. During the upward movement of the pressure plate 10, the spring 11 will be squeezed, and the impact on the flexible blocking plate 1 will be buffered by the reaction force of the spring 11 until the wing plate 3 on the back of the flexible blocking plate 1 contacts the rigid blocking plate 2. The gantry crane after buffering is blocked by the rigid blocking plate 2, which can ensure that the gantry crane is successfully blocked and prevent the gantry crane from rushing out of the track. The rigid-flexible blocking method can effectively resist the inertial impact force generated when the gantry crane moves to the end of the track, so as to ensure the safety of the gantry crane and the excellent use effect.

[0038] The stop structure provided in this embodiment effectively buffers the inertial impact force generated when the gantry crane moves to the end of the track, preventing the gantry crane from rushing out of the track, ensuring the safety of the gantry crane's travel, and further ensuring construction safety.

[0039] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are readily apparent to those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
